ZusammenfassungDurch das COVID-19-Register (www.covid19-rheuma.de) der Deutschen Gesellschaft für Rheumatologie erfolgte erstmalig die Erfassung und systematische Evaluation einer viralen Infektion bei Patienten mit entzündlich rheumatischen Erkrankungen (ERE). Hierdurch war und ist eine schnelle Generierung von wissenschaftlichen Daten möglich, welche helfen, die Betreuung von Patienten mit ERE im Rahmen der Pandemie zu verbessern. Neben der Bestätigung allgemeiner Risikofaktoren – auch für Patienten mit ERE – wie Patientenalter und Komorbiditäten (z. B. kardiovaskuläre, chronische Lungen- und Nierenerkrankungen) konnten die Einnahme von Glukokortikoiden und die Krankheitsaktivität der rheumatischen Erkrankung als krankheitsspezifische Risikofaktoren für die Notwendigkeit einer stationären Behandlung wegen COVID-19 identifiziert werden. Auswertungen der kontinuierlich wachsenden Kohorte von Patienten mit entzündlich rheumatischen Erkrankungen und einer COVID-19-Infektion erlauben, Handlungsempfehlungen für die Betreuung der Patienten auf eine bessere Evidenz zu stützen. Die Kooperation mit internationalen rheumatologischen Registern (z. B. europäisches COVID-19-Register für ERE) ermöglicht Analysen aggregierter Kohortendaten von Patienten mit entzündlich rheumatischen Erkrankungen und einer SARS-CoV-2-Infektion für internationale Vergleiche und statistisch noch besser abgesicherte Aussagen.

ObjectivesSystemic sclerosis is a heterogeneous, multisystem disease. It can occur at any age, but most patients develop the disease between the age of 40 to 50 years. There is controversial evidence on whether/how the age at disease onset affects their clinical phenotype. We here investigate the relationship between age at disease onset and symptoms in a large cohort of SSc patients (lcSSc, dcSSc and SSc-overlap syndromes).MethodsClinical data of the registry of the German Network for Systemic Scleroderma including 3281 patients were evaluated and subdivided into three age groups at disease onset (60 years).ResultsAmong all SSc patients, 24.5% developed their first non-Raynaud phenomenon symptoms at the age 60 years), except for gastrointestinal and musculoskeletal involvement. No significant difference was found for the use of corticosteroids. However, significantly, fewer patients older than 60 years received immunosuppressive treatment.ConclusionIn this large registry, ∼25% of patients developed SSc at an age above 60 years with an increased frequency of lcSSc. In this age group, an onset of internal organ involvement was significantly accelerated across all three subsets. These findings suggest that, in the elderly cohort, more frequent follow-up examinations are required for an earlier detection of organ complications.

IntroductionSeveral risk factors for severe COVID-19 specific for patients with inflammatory rheumatic and musculoskeletal diseases (RMDs) have been identified so far. Evidence regarding the influence of different RMD treatments on outcomes of SARS-CoV-2 infection is still poor.MethodsData from the German COVID-19-RMD registry collected between 30 March 2020 and 9 April 2021 were analysed. Ordinal outcome of COVID-19 severity was defined: (1) not hospitalised, (2) hospitalised/not invasively ventilated and (3) invasively ventilated/deceased. Independent associations between demographic and disease features and outcome of COVID-19 were estimated by multivariable ordinal logistic regression using proportional odds model.Results2274 patients were included. 83 (3.6%) patients died. Age, male sex, cardiovascular disease, hypertension, chronic lung diseases and chronic kidney disease were independently associated with worse outcome of SARS-CoV-2 infection. Compared with rheumatoid arthritis, patients with psoriatic arthritis showed a better outcome. Disease activity and glucocorticoids were associated with worse outcome. Compared with methotrexate (MTX), TNF inhibitors (TNFi) showed a significant association with better outcome of SARS-CoV-2 infection (OR 0.6, 95% CI0.4 to 0.9). Immunosuppressants (mycophenolate mofetil, azathioprine, cyclophosphamide and ciclosporin) (OR 2.2, 95% CI 1.3 to 3.9), Janus kinase inhibitor (JAKi) (OR 1.8, 95% CI 1.1 to 2.7) and rituximab (OR 5.4, 95% CI 3.3 to 8.8) were independently associated with worse outcome.ConclusionGeneral risk factors for severity of COVID-19 play a similar role in patients with RMDs as in the normal population. Influence of disease activity on COVID-19 outcome is of great importance as patients with high disease activity—even without glucocorticoids—have a worse outcome. Patients on TNFi show a better outcome of SARS-CoV-2 infection than patients on MTX. Immunosuppressants, rituximab and JAKi are associated with more severe course.

Objective.Scleroderma renal crisis (SRC) is a severe life-threatening manifestation in patients with systemic sclerosis (SSc). However, the knowledge about risk factors for SRC is limited. We determined here the frequency of SRC and identified risk factors for the prediction of SRC.Methods.Based on regular followup data from the German Network for Systemic Scleroderma, we used univariate and multivariate generalized estimating equations to analyze the association between clinical variables, SSc subsets, therapy [i.e., angiotensin-converting enzyme inhibitors (ACEi), corticosteroids], and the occurrence of SRC.Results.Data of 2873 patients with 10,425 visits were available for analysis with a mean number of registry visits of 3.6 ± 2.8 and a mean time of followup of 3.6 ± 3.8 years. In total, 70 patients developed SRC (70/2873, 2.4%). Of these patients, 57.1% (40/70) were diagnosed with diffuse cutaneous SSc, 31.4% (22/70) with limited cutaneous SSc, and 11.4% (8/70) with SSc-overlap syndromes. Predictive independent factors with the highest probability for SRC were positive anti-RNA polymerase antibodies (RNAP), a history of proteinuria prior to SRC onset, diminished DLCO, and a history of hypertension. Interestingly, positive antitopoisomerase autoantibodies did not predict a higher risk for SRC. Further, patients with SRC were significantly more frequently treated with ACEi and corticosteroids without being independently associated with SRC.Conclusion.In this cohort, SRC has become a rare complication. By far the highest risk for SRC was associated with the detection of anti-RNAP and proteinuria.

Objectives To evaluate the influence of the SARS-CoV-2 pandemic on the adherence of patients with inflammatory rheumatic diseases (IRD) to their immunomodulatory medication during the three-month lockdown in Germany. Methods From 16th March until 15th June 2020, IRD patients from private practices and rheumatology departments were asked to answer a questionnaire addressing their behaviour with respect to their immunomodulating therapy. Eight private practices and nine rheumatology departments that included rheumatology primary care centres and university hospitals participated. A total of 4252 questionnaires were collected and evaluated. Results The majority of patients (54%) were diagnosed with RA, followed by psoriatic arthritis (14%), ankylosing spondylitis (10%), connective tissue diseases (12%) and vasculitides (6%). Most of the patients (84%) reported to continue their immunomodulatory therapy. Termination of therapy was reported by only 3% of the patients. The results were independent from the type of IRD, the respective immunomodulatory therapy and by whom the patients were treated (private practices vs rheumatology departments). Younger patients ( Conclusion The data show that most of the patients continued their therapy in spite of the pandemic. A significant change in behaviour with regard to their immunomodulatory therapy was not observed during the three months of observation. The results support the idea that the immediate release of recommendations of the German Society of Rheumatology were well received, supporting the well-established physician–patient relationship in times of a crisis.

IntroductionWhether patients with inflammatory rheumatic and musculoskeletal diseases (RMD) are at higher risk to develop severe courses of COVID-19 has not been fully elucidated. Aim of this analysis was to describe patients with RMD according to their COVID-19 severity and to identify risk factors for hospitalisation.MethodsPatients with RMD with PCR confirmed SARS-CoV-2 infection reported to the German COVID-19 registry from 30 March to 1 November 2020 were evaluated. Multivariable logistic regression was used to estimate ORs for hospitalisation due to COVID-19.ResultsData from 468 patients with RMD with SARS-CoV-2 infection were reported. Most frequent diagnosis was rheumatoid arthritis, RA (48%). 29% of the patients were hospitalised, 5.5% needed ventilation. 19 patients died. Multivariable analysis showed that age >65 years (OR 2.24; 95% CI 1.12 to 4.47), but even more>75 years (OR 3.94; 95% CI 1.86 to 8.32), cardiovascular disease (CVD; OR 3.36; 95% CI 1.5 to 7.55), interstitial lung disease/chronic obstructive pulmonary disease (ILD/COPD) (OR 2.79; 95% CI 1.2 to 6.49), chronic kidney disease (OR 2.96; 95% CI 1.16 to 7.5), moderate/high RMD disease activity (OR 1.96; 95% CI 1.02 to 3.76) and treatment with glucocorticoids (GCs) in dosages >5 mg/day (OR 3.67; 95% CI 1.49 to 9.05) were associated with higher odds of hospitalisation. Spondyloarthritis patients showed a smaller risk of hospitalisation compared with RA (OR 0.46; 95% CI 0.23 to 0.91).ConclusionAge was a major risk factor for hospitalisation as well as comorbidities such as CVD, ILD/COPD, chronic kidney disease and current or prior treatment with GCs. Moderate to high RMD disease activity was also an independent risk factor for hospitalisation, underlining the importance of continuing adequate RMD treatment during the pandemic.

BackgroundAt the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease 2019 (COVID-19) pandemic, the influence of anti-inflammatory therapy on the course of SARS-CoV-2 infection in patients with inflammatory rheumatic diseases (IRD) was unknown. In the meantime, several data indicate an association of severe courses of COVID-19 with the use of rituximab (RTX).ObjectivesTo gather further knowledge about SARS-CoV-2 infections in RTX-treated IRD patients, data from the German COVID-19-IRD-registry were analysed.MethodsHospitalisation was used as a surrogate of COVID-19 severity. Baseline characteristics, disease features, medication and outcome of COVID-19 were compared in RTX-treated inpatients and outpatients.ResultsIn total, 3592 cases were reported in the registry, which included 130 RTX patients (3.6%) for our analysis. RTX-treated inpatients were older than RTX-treated outpatients (median age 63 y vs 56 y, p=0.007). Patients with granulomatosis with polyangiitis treated with RTX (n=32) showed a significant higher COVID-19 related hospitalisation rate (33% vs 11%, p=0.005), which was not the case for patients with rheumatoid arthritis (49% vs 50%). Cardiovascular comorbidities were reported more frequently in hospitalised RTX-treated patients (20% vs. 6%, p=0.032). More than 50% of the RTX-treated inpatients developed COVID-19 related complications, e.g. acute respiratory distress syndrome. The median time period between the last RTX treatment and SARS-CoV-2 infection was shorter in inpatients than in non-hospitalised patients (3 (range 0-17) vs. 4 months (range -29), p=0.039). The COVID-19 related mortality rate was 14% (n=19) in RTX-treated IRD patients. In RTX-treated inpatients and outpatients, there were no relevant differences with respect to the use of concomitant glucocorticoids or other disease modifying anti-rheumatic drugs, disease activity, median last RTX dose or median number of immunomodulatory drugs prior to RTX treatment.ConclusionIn addition to general risk factors, such as age and comorbidities, it is already known that IRD patients treated with RTX show a higher rate of severe COVID-19. In our registry, RTX-treated patients with granulomatosis with polyangiitis appear to be at even higher risk to develop severe COVID-19 compared to other IRD. Moreover, the shorter the time since the last RTX treatment, the higher seems to be the risk of developing severe COVID-19. This might be explained by a more profound B-cell depletion in the first weeks after RTX treatment warranting further studies.Disclosure of InterestsNone declared

BackgroundSARS-CoV-2 vaccines offer the most effective way to reduce the risk of severe COVID-19. Recent data indicate sufficient immune response after vaccination in most patients with inflammatory rheumatic diseases (IRD) on immunomodulatory treatments.ObjectivesTo investigate the clinical profile of SARS-CoV-2 breakthrough infections among double and triple vaccinated patients with IRD.MethodsData from the German COVID-19-IRD registry, collected by treating rheumatologists between February 2021 and January 2022 were analysed. Patients double or triple vaccinated against COVID-19 ≥14 days prior to proven SARS-CoV-2 infection were identified, and type of IRD, vaccine, immunomodulation, comorbidities and outcome of the infection were compared with 737 unvaccinated IRD-patients with COVID-19.ResultsIn total, 271 cases of breakthrough infections were reported, 250 patients (91%) had received two doses of vaccines, 21 (9%) patients three. More than 70% of the patients received Pfizer/Biontech vaccine for the first, second and third vaccination. The median time from second/third vaccine dose to infection was 148 days (range 14-302) days. Most of the patients were diagnosed with inflammatory joint diseases (Table 1). Most of the patients were treated with methotrexate (Table 1). The use of Januskinase inhibitors(i) was more frequently reported in double vaccinated patients (10.4% vs 4.8%), whereas tumor necrosis (TNF)i were reported more often in triple vaccinated patients (33.3% vs. 22.8). Hospitalisation rate was higher in unvaccinated IRD-patients than in vaccinated ones, while fatality rate was similar in unvaccinated and double vaccinated patients. Although the rate of comorbidities and median age were higher in triple-vaccinated patients, infected patients showed a lower rate of hospitalisation, neither COVID-19 related complications, nor the need of oxygen treatment or death.Table 1.Profile of vaccinated IRD patientsunvaccinated2ndvaccination3rdvaccinationNumber (737)%Number (250)%Number (21)%Age56 (18-93)57 (22-90)63 (35-88)Female47864.915863.21361.9BMI26.8 (17-53)26.7 (17-55)25.4 (18-41)Inflammatory rheumatic disease (multiple selections possible)Inflammatory joint diseases56175.918674.41676.2Connective tissue diseases10112.8301229.6Vasculitis719.6228.8314.3Other IRD638.52911.614.8Immunomodulation (multiple selections possible)Glucocorticoid21228.86726.8523.8Methotrexate27036.69036838.1Azathioprine192.672.8//Cyclosporine30.410.4//Leflunomide506.872.8//Hydroxychloroquine7910.7239.214.8Sulfasalazine202.793.6//JAKi547.32610.414.8TNFi15821.45722.8733.3Abatacept91.231.2//Rituximab212.8114.414.8Other biologics597.93212.829.6Mycophenolate15241.6//Immunoglobulines20.310.4//Apremilast40.5////Cyclophosphamide10.110.4//No immunomodulation7410228.814.8No/low disease activity62584.822389.21885.7Moderate/high disease activity10213.82710.8314.3ComorbiditiesCardiovascular diseases32944.6130521361.9Diabetes mellitus7610.32510//Osteoporosis435.8218.429.5Chronic renal failure405.4166.4419Cancer/history of cancer152.0104314.3COPD253.4104//ILD162.272.8//Bronchial asthma344.6166.4//Pregnancy70.910.414.8No comorbidity25434.59738.8523.8Complications due to COVID-19Hospitalisation13518.32911.629.5Oxygen treatment11415.5249.6//Invasive ventilation253.493.6//Death162.272.8//ConclusionIn this cohort of triple-vaccinated IRD patients no fatal courses and no COVID-19 related complications were reported, although median age and rate of comorbidities were higher compared to double-vaccinated and unvaccinated patients. These results support the general recommendations to reduce the risk of severe COVID-19 disease by administering three doses of vaccine, especially in patients with older age, presence of comorbidities, and on immunomodulatory treatment.Disclosure of InterestsNone declared

BackgroundJuvenile systemic sclerosis (jSSc) is an orphan autoimmune disease with a prevalence of 3 in 1 000 000 children. Information on long-term development of organ involvement and clinical characteristics of jSSc patients in adulthood are lacking. It was believed that patients in adult cohorts may represent a survival biased population.ObjectivesTo assess differences in clinical characteristics of jSSc-onset patients from the pediatric age group, with a mean disease duration of 3 years, compared to the adult age jSSc-onset group, with a mean disease duration of 18.5 years.MethodsWe extracted clinical data at time of inclusion into the cohorts from the Juvenile Scleroderma Inception Cohort (jSScC) and data from juvenile-onset adult SSc patients from the European Trials and Research Group (EUSTAR) cohort. We compared the clinical characteristics of the patients by descriptive statistics.ResultsWe extracted data of 187 jSSc patients from the jSScC and 236 patients from EUSTAR. The mean age at time of assessment was 13.4 years old in the jSScC and 32.4 years old in EUSTAR. The mean disease duration since first non-Raynaud was 3.0 years in jSScC and 18.5 years in the EUSTAR (Table 1).We found significant differences between the cohorts. There were more female patients in EUSTAR (87.7% versus 80.2%, p=0.04). More patients had diffuse subtype in jSScC (72.2% versus 40%, pTable 1.Clinical characteristics of juvenile onset SSc patients at time point of the inclusion into the juvenile scleroderma inception (jSScC) cohort and in the adult EUSTAR- cohortjSScCEUSTAR CohortP valueNumber of patients1872360.04Age in years, mean (SD)13.4 (3.6)32.4 (15.4)Female patients, n (%)150 (80.2%)207 (87.7%)jSSC Subtype, n (%)diffuse135 (72.2%)87 (38.1%)limited52 (27.8%)121 (53.3%)Age at Raynaud onset in years, mean (SD)10.0 (3.9)13.7 (9.1)Age at non-Raynaud onset in years, mean (SD)10.3 (3.9)11.7 (3.7)Duration since first Raynaud symptoms in years, mean (SD)3.4 (2.7)20.6 (15.9)Duration since first non-Raynaud symptoms in years, mean (SD)3.0 (2.7)18.5 (15.6)Raynaud´s, n (%)170 (90.9%)222 (94.9%)ANA positive, n (%)166 (91.7%)210 (92.9%)0.99Anti-Scl 70 positive, n (%)62 (34.4%)73 (33.3%)0.68Modified Rodnan Skin Score, mean (SD)5%Data missingModified Rodnan Skin Score, mean (SD)14.2 (11.7)12.1 (14.5)0.02Digital ulceration, n (%)At the time of inclusion33 (17.8)21 (26.6%)0.01In the past history100 (54.1%)34 (43%)Telangiectasia62 (37.4%)42 (53.2%)0.04FVC, mean (SD)84.1 (18.6)84 (22.4)0.96DLCO, mean (SD)75.4 (19.2)86.3 (19.9)Arterial hypertension, n (%)10 (5.4%)20 (8.5%)0.26Renal crisis, n (%)03 (1.3%)0.26Esophageal involvement, n (%)63 (33.7%)149 (63.7%)Intestinal involvement, n (%)62 (33.2%)56 (23.8%)0.04Articular involvement, n (%)34 (18.3%)27 (11.6%)0.06Muscular involvement, n (%)31 (19.3%)46 (19.8%)0.45ConclusionPatients with jSSc-onset who are currently adult age (defined as >18 years of age) are less frequently male and from the diffuse subset, have lower mRSS, less digital ulcers and intestinal involvement. This might represent a combination of both survival bias and/or be explained by the longer observation time with less active disease (i.e. natural progression decreased mRSS over time). Further long-term observational studies with jSSc patients are required to address this issue.Disclosure of InterestsNone declared

ObjectivesPatients with inflammatory rheumatic diseases (IRD) infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be at risk to develop a severe course of COVID-19. The influence of immunomodulating drugs on the course of COVID-19 is unknown. To gather knowledge about SARS-CoV-2 infections in patients with IRD, we established a registry shortly after the beginning of the pandemic in Germany.MethodsUsing an online questionnaire (www.COVID19-rheuma.de), a nationwide database was launched on 30 March 2020, with appropriate ethical and data protection approval to collect data of patients with IRD infected with SARS-CoV-2. In this registry, key clinical and epidemiological parameters—for example, diagnosis of IRD, antirheumatic therapies, comorbidities and course of the infection—are documented.ResultsUntil 25 April 2020, data from 104 patients with IRD infected with SARS-CoV-2 were reported (40 males; 63 females; 1 diverse). Most of them (45%) were diagnosed with rheumatoid arthritis, 59% had one or more comorbidities and 42% were treated with biological disease-modifying antirheumatic drugs. Hospitalisation was reported in 32% of the patients. Two-thirds of the patients already recovered. Unfortunately, 6 patients had a fatal course.ConclusionsIn a short time, a national registry for SARS-CoV2-infected patients with IRD was established. Within 4 weeks, 104 cases were documented. The registry enables to generate data rapidly in this emerging situation and to gain a better understanding of the course of SARS-CoV2-infection in patients with IRD, with a distinct focus on their immunomodulatory therapies. This knowledge is valuable for timely information of physicians and patients with IRD, and shall also serve for the development of guidance for the management of patients with IRD during this pandemic.

Background:Patients with inflammatory rheumatic diseases (IRD) and infection with SARS-CoV-2 may be at risk to develop a severe course of COVID-19. To gather knowledge about SARS-CoV-2 infections in IRD patients, a national registry was established to elucidate IRD specific profiles of COVID-19.Objectives:To identify risk factors for hospitalisation.Methods:Patients from the German registry on SARS-CoV-2 infection in IRD were analysed. Patients are enrolled with a pre-existing IRD and a positive lab-result for a SARS-CoV-2 infection. The main outcome parameter was hospitalisation versus non-hospitalisation. Multivariable logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI). Covariates included in the model were age group, gender, key comorbidities (cardiovascular, lung diseases, chronic renal insufficiency), prior and/or current use of glucocorticosteroids (GC) or NSAIDs and remission.Results:Until May 17th, 2020, data from 192 IRD patients with SARS-CoV-2 infection were reported (67 males; 124 females; 1 diverse). 64 patients were hospitalised, 21 patients were ventilated non-invasively/invasively and 15 patients died.Baseline characteristics are shown in table 1, stratified into the patient groups non-hospitalisation, hospitalisation without ventilation, and hospitalisation with ventilation. Non-hospitalised patients were younger, had less comorbidities and were less often treated with GC. In the group of hospitalised patients compared to non-hospitalised patients more patients were male (42% vs 32% male) with an even higher proportion in the ventilated patient group (57% male).In the multivariable logistic regression model, age>65 years (OR 5.1; 95%CI 2.3-11.4), cardiovascular comorbidity (OR 2.3; 95%CI 1.0-5.0), and prior and/or current treatment with GC (OR 2.6; 95%CI 1.2-5.4) were independently associated with hospitalisation.Parameter, N (%)Non-hospitalisation128 (66.7)Hosp. without ventilation42 (22.4)Hosp. with ventilation21 (10.9)Age [years], mean (SD)53.8 (13.4)65.2 (15.5)69.7 (9.9)Female87 (68.5)28 (65.1)9 (42.9)RA60 (46.9)24 (55.8)12 (57.1)Psoriasis23 (18)3 (7)3 (14.3)Axial spondyloarthritis14 (10.9)2 (4.7)0Lupus7 (5.5)1 (2.3)0Remission of IRD67 (52.3)23 (53.5)4 (19)Number of comorbidities, mean (SD)1 (1.2)1.8 (1.4)2.4 (1.5)Cardiovascular disease42 (32.8)25 (58.1)16 (76.2)Pulmonary disease16 (12.5)8 (18.6)8 (38.1)Chronic renal insufficiency5 (3.9)7 (16.3)4 (19)Cancer2 (1.6)4 (9.3)2 (9.5)Obesity (BMI>30)23 (18)5 (11.6)3 (14.3)Diabetes3 (2.3)7 (16.3)4 (19)Other comorbidities20 (15.6)9 (20.9)6 (28.6)csDMARD (without HCQ)59 (46.1)25 (58.1)8 (38.1)HCQ13 (10.2)1 (2.3)2 (9.5)bDMARD48 (37.5)15 (34.9)8 (38.1)tsDMARD5 (3.9)1 (2.3)1 (4.8)Glucocorticosteroids47 (37)29 (67.4)13 (61.9)NSAIDs21 (16.4)5 (11.6)1 (4.8)Conclusion:As has been described for COVID-19 in general, also in IRD male gender may be associated with a more severe course of the infection as the descriptive analysis of data shows.

The current COVID-19 pandemic inherits an unprecedented challenge for the treating rheumatologists. On the one hand, antirheumatic drugs can increase the risk of infection and potentially deteriorate the course of an infection. On the other hand, an active inflammatory rheumatic disease can also increase the risk for an infection. In the recommendations of the German Society for Rheumatology (www.dgrh.de), it is recommended that our patients continue the antirheumatic therapy to maintain remission or low state of activity despite the pandemic. In this study, patients with inflammatory rheumatic disease were asked in the first weeks of the pandemic on their opinion of their immunomodulating therapy. The result shows that over 90% of the patients followed the recommendation of the rheumatologist to continue the antirheumatic therapy, and only a small percentage of the patients terminated the therapy on their own. This result was independent of the individual anti-rheumatic therapy. Taken together, the results of this study illustrate not only the trustful patient-physician partnership in a threatening situation but also the high impact of state-of-the art recommendations by the respective scientific society.

Der Morbus Whipple (MW) ist eine seltene chronische Multiorganerkrankung, welche durch Tropheryma whipplei (TW), ein ubiquitar vorkommendes Bakterium, ausgelost werden kann. TW kann in den betroffenen Geweben durch einen histologischen Nachweis von PAS(„periodic acid-Schiff reaction“)-positiven Makrophagen und in der Polymerasekettenreaktion (PCR) nachgewiesen werden. Klinisch gepragt wird der MW haufig durch eine gastrointestinale Klinik (Diarrhoe, kolikartige Bauchschmerzen, Gewichtsverlust). Arthritiden werden haufig beobachtet, sodass eine initiale Fehldiagnose einer seronegativen rheumatoiden Arthritis mit konsekutiver immunsuppressiver Therapie nicht selten ist. Der MW kann sich unterschiedlich manifestieren und mit einer Beteiligung weiterer Organsysteme einhergehen (z. B. kardiale oder neurologische Beteiligung), was den klinischen Verdacht bzw. die Diagnosestellung erschwert. Die hier beschriebenen 3 Falle mit unterschiedlicher fuhrender Symptomatik (initiale Fehldiagnose einer seronegativen rheumatoiden Arthritis, Spondylarthritis und eines Morbus Still) illustrieren den Facettenreichtum des MW und sollen demonstrieren, dass die dem Bereich der Gastroenterologie zugeordnete und v. a. mit gastrointestinaler (GI) Symptomatik assoziierte Erkrankung auch ohne diese Beschwerden auftreten kann. Bei klinischem Verdacht sollte der Erregernachweis aus dem jeweils symptomatischen Organ angestrebt werden. Die 01/2015 publizierte Deutsche S2k-Leitlinie zu gastrointestinalen Infektionen und MW fasst den aktuellen Kenntnisstand zum MW zusammen. Als Primartherapie kommen liquorgangige Antibiotika zum Einsatz, typischerweise Ceftriaxon, gefolgt von einer mehrmonatigen Cotrimoxazol-Therapie.

ObjectivesThe aim of this study was to adapt the Systemic Sclerosis Quality of Life Questionnaire (SScQoL) into six European cultures and validate it as a common measure of quality of life in systemic sclerosis (SSc).MethodsThis was a seven-country (Germany, France, Italy, Poland, Spain, Sweden and UK) cross-sectional study. A forward–backward translation process was used to adapt the English SScQoL into target languages. SScQoL was completed by patients with SSc, then data were validated against the Rasch model. To correct local response dependency, items were grouped into the following subscales: function, emotion, sleep, social and pain and reanalysed for fit to the model, unidimensionality and cross-cultural equivalence.ResultsThe adaptation of the SScQoL was seamless in all countries except Germany. Cross-cultural validation included 1080 patients with a mean age 58.0 years (SD 13.9) and 87% were women. Local dependency was evident in individual country data. Grouping items into testlets corrected the local dependency in most country specific data. Fit to the model, reliability and unidimensionality was achieved in six-country data after cross-cultural adjustment for Italy in the social subscale. The SScQoL was then calibrated into an interval level scale.ConclusionThe individual SScQoL items have translated well into five languages and overall, the scale maintained its construct validity, working well as a five-subscale questionnaire. Measures of quality of life in SSc can be directly compared across five countries (France, Poland Spain, Sweden and UK). Data from Italy are also comparable with the other five countries although require an adjustment.

Background:Patients with rheumatic and musculoskeletal diseases (RMD) might have an increased risk for infection due to their immunomodulatory treatment, secondary to their disease and comorbidities. Recent studies suggest a decreased risk of severe COVID-19 in RMD-patients treated with biologics.Objectives:The aim of this study was to assess courses of RMD patients treated with TNF-inhibitors (TNF-I) included in the German COVID-19 registry.Methods:In the German physician-reported COVID-19-RMD registry, patients with an RMD and confirmed SARS-CoV-2-infection were documented (data entered between March 30, 2020 and January 30, 2021). We analysed TNF-I treated patients, their course and outcome of the infection. Data were compared to RMD-patients treated with other immunomodulatory drugs (OID) than TNF-I.Results:A total of 269 patients were treated with a TNF-I (57% female) compared to 874 patients who were treated with OID (68% female). Median age was 52 years (range: 19-87) in the TNF-I-group versus 58 years (range: 18-91) in the OID-group. Rheumatoid arthritis was the most common diagnosis (38% in TNF-I-group vs. 52% in the OID-group), followed by ankylosing spondylitis (32% vs. 6%), psoriatic arthritis (22% vs. 11%) and other RMD (9% vs. 31%). Adalimumab (35%) and etanercept (35%) were the most frequently used TNF-I (tab. 1). Glucocorticoids (GC) were used in 22% of TNF-I-treated patients and in 42% of the OID-group.Under TNF-I, stable disease was reported prior to the SARS-CoV-2-infection in 53% of the patients (OID-group: 47%), followed by low disease activity in 35% (OID: 34%), moderate disease activity in 6% (OID: 12%) and high disease activity in 4% (OID: 3%). Most frequent comorbidities were arterial hypertension (29% under TNF-I vs. 35% under OID), diabetes (8% vs. 11%) and cardiovascular diseases (7% vs. 12%).The most common reported COVID-19 symptoms were dry cough (57% vs. 55%), fever (53% vs. 61%) and fatigue (50% vs. 49%). Hospitalization due to SARS-CoV infection was required in only 12% of the TNF-I-treated cases vs. in 29% in the OID-group. Oxygen treatment was necessary in 5% of the patients under TNF-I compared to 22% under OID and invasive ventilation in 2% in the TNF-I-group compared to 6% under OID. Most notably, no fatal courses of COVID-19 were reported among the 269 RMD-patients treated with TNF-I versus 49 deaths in the 874 cases (5.6%) treated with OID. Focussing on the hospitalizated TNF-I patients, the rate of concomitant GC use (pConclusion:High or moderate RMD-disease activity is an important factor associated with severity of COVID-19 including mortality. In this large cohort RMD patients treated with TNF-I show a low hospitalisation rate and no fatal course. This is reassuring for patients and treating rheumatologists to use TNF-I to control RMD disease activity. The use of glucocorticoids and high disease activity seem to counteract possible protective effects of TNF-I.Table 1.TNF inhibition (269)Other immunomodulation (874)Total patientsRate (%)Total patientsRate (%)Disease activitystable1415340847low933529934Moderate15610812High104293Comorbiditiescardiovascular diseases18710412arterial hypertension772930335bronchial asthma124657COPD/interstitial lung disease1148610chronic renal failure93779Osteoporosis135678Diabetes2289211COVID-19 related symptomsFever1425347855dry cough1525753061Expectoration3112839muscular pain973628032Fatigue1355042449Headache1013823727shortness of breath491824528no symptoms239566COVID-19 outcomeOutpatients2378861971Inpatients321225529need of oxygen treatment18718922invasive ventilation52496fatal course00496TNF inhibitorsAdalimumab9535Infliximab239Certolizumab3312Golimumab249Etanercept9435GC and disease activity in TNF-I treated patientsTNF-I inpatients treated with GC18/3256p< 0.001TNF-I outpatients treated with GC42/23718TNF-I inpatients with high disease activity4/3213TNF-I outpatients with high disease activity6/2376p= 0.005Acknowledgements:The authors would like to thank all physicians and personnel involved in the documentation of the cases in our registry.Disclosure of Interests:None declared

Background:Tocilizumab (TCZ) showed trends for improving skin fibrosis and prevented progression of lung fibrosis in patients with systemic sclerosis (SSc) in placebo-controlled randomised clinical trials (RCTs). However, safety and effectiveness of TCZ beyond these selected and enriched clinical trial populations in SSc is still unknown.Objectives:To assess safety and effectiveness of TCZ treatment compared to standard of care in SSc patients from the large, multicentre, observational, real-life EUSTAR network/database using propensity score matching.Methods:SSc patients from the EUSTAR network/database, who fulfilled the ACR/EULAR 2013 classification criteria, with a baseline and a follow-up visit at 12±3 months, receiving TCZ or standard of care (controls), were selected. The following variables were used for the propensity score matching (1:1): age at diagnosis, gender, disease subtype, baseline modified Rodnan skin score (mRSS), forced vital capacity (FVC), and diffusing capacity for carbon monoxide (DLCO), co-therapy with immunosuppressives, disease duration, and year of treatment. Primary endpoints were mRSS and FVC at 12±3 months follow-up compared between the groups, using paired t-tests. Secondary endpoints were the percentage of progressive/regressive patients for skin and lung at 12±3 months follow-up according to standard definitions (1,2). Sensitivity analyses assessed pre-processing decisions (selection of most recent vs. random observation for control patients with multiple suitable time intervals), as well as the matching method (optimal vs. exact matching). Missing values were addressed with 100-fold multiple imputation using chained equations. Safety data were analysed in all patients. The study including the statistical analysis plan was pre-registered at www.drks.de (DRKS-ID: DRKS00015537).Results:We identified 93 SSc patients treated with TCZ and 2370 SSc patients with standard of care who fulfilled the inclusion criteria. Forty nine (57.7%) of the TCZ treated patients were diffuse, eight patients were not classified, disease duration was (mean±SD) 6.35±5.40 years, their baseline mRSS was 15.05±10.85, and 76 (81.7%) received immunosuppressive therapy in addition to TCZ.Through multiple imputation and propensity score matching, 100 imputed sets of 93 pairs of TCZ/controls were generated. Comparison between groups showed consistent effects of TCZ across all pre-defined primary and secondary endpoints: mRSS was lower in the TCZ group (mean difference (95% confidence interval (CI)) -1.8 (-4.79 to 1.19), p=0.24, Figure 1A). Similarly, FVC % predicted was higher in the TCZ group mean difference (2.25, 95% CI -4.57 to 9.06), p=0.51, Figure 1B). Considering secondary endpoints, the percentage of skin progressors as well as lung progressors at follow up was lower in the TCZ group (odds ratio OR 0.67 (95% CI 0.07 to 6.41), p=0.74 and OR 0.53 (95% CI 0.16 to 1.7); p=0.2, respectively. Consistently, the percentage of regressors for skin (OR 1.6 (95% CI 0.56 to 4.54), p=0.38) and for lung (OR 1.74 (95% CI 0.66 to 4.58), p=0.26) was higher in TCZ. These results were robust regarding the sensitivity analyses. Safety analysis confirmed previously reported adverse event profiles.Conclusion:In this large, observational, controlled, real-life EUSTAR study, effectiveness of TCZ did not reach statistical significance compared to standard of care treatment but showed consistent positive effects of TCZ on skin and lung fibrosis across all pre-defined primary and secondary endpoints confirming data from recent RCTs.References:[1]Prediction of improvement in skin fibrosis in diffuse cutaneous systemic sclerosis: a EUSTAR analysis.

Background: Gastroesophageal reflux (GER) is common in SSc and thus treatment with anti-acid therapy (AAT) is frequent. An association between GER and SSc-ILD progression has been hypothesized. However, outcomes of AAT on disease progression in SSc-ILD has only sparsely been studied. Methods: The German Network for Systemic Scleroderma (DNSS), which includes SSc pts. prospectively, was analyzed for SSc-ILD. Those without SSc progression at ILD 1st diagnosis were categorized in AAT vs. no-AAT users and outcome was assessed. Results: SSc-ILD was reported in 1886 out of 4306 pts. 929 of SSc-ILD pts had no disease progression at ILD 1st diagnosis. 514 used AAT while 415 did not. Baseline characteristics were similar with regards to age, gender, BMI, time since SSc diagnosis, mRSS, esophageal involvement and steroid use. Significant differences in no-AAT vs. AAT were found for lung function (PFT: DLCO 63% vs. 58%, p Conclusions: This current analysis suggests, that AAT use may be correlated with ILD progression in SSc. Yet, results may have been biased by differences in baseline PFT and favorable survival effects have to be respected. Prospective trials are needed to assess the impact of AAT in SSc-ILD.

Background: Data from prospective clinical trials support the use of immunomodulatory therapies (IT) for treatment of SSc-ILD. However, outcomes for SSc-ILD in respect to IT use in large real-life cohorts has only sparsely been reported. Methods: The German Network for Systemic Scleroderma (DNSS), which includes SSc pts. prospectively, was analyzed for SSc-ILD. Patients were categorized in IT vs. no-IT users and outcome was assessed. Results: SSc-ILD was reported in 1886 out of 4306 pts. 1109 used IT while 777 did not. Baseline characteristics at ILD diagnosis were similar with regards to gender, FVC (no IT 82% vs. IT 78%, p=0.117) and use of PH drugs. Significant differences in no-IT vs. IT were found for age, time since SSc diagnosis (10 vs. 7 years p Conclusions: In this large real-life cohort of SSc-patients, the use of immunomodulatory therapies had no significant impact on outcomes in SSc-ILD. Yet, differences in baseline characteristics have to be taken into account.

Background SSc is a heterogeneous multisystem connective tissue disease. The majority of patients (pts) develop initial clinical symptoms between the ages of 30-50 years (yrs). It is not yet known whether the age of onset has an influence on the development of a distinct clinical phenotype. Objectives Investigating the relationship between age at disease onset and the development of clinical characteristics using data of the German Network for Systemic Scleroderma. Methods We evaluated 2928 patient data, subdivided them into 3 age groups at disease onset ( 60 years) and correlated the age at disease onset with specific clinical characteristics. Results Overall, 24% of pts developed first non-RP symptoms at the age of 60yrs developed significantly (p Conclusion In this registry, approximately one quarter of pts developed SSc at an age above 60yrs, predominantly having a lcSSc subtype. Although these pts have been diagnosed with the mild form of SSc, pts with a lcSSc subtype at a higher age (>60yrs) had more frequent a PH and showed a more rapid disease progression than the youngest pts. These findings may have an important influence on recommendations on diagnosis, frequency of follow-ups and therapy of SSc in different age groups.

Background Pulmonary involvement is the leading cause of death in SSc and can manifest as interstitial lung disease (ILD), pulmonary hypertension (PAH) or a combination (ILD-PH). Aim of this analysis was to determine prevalence, clinical characteristics and outcomes of different forms within the German SSc Network. Objectives Methods SSc patients were analyzed for pulmonary involvement, clinical characteristics and outcome. Results There were 3699 pts in 42 centers with a mean follow up time of 34.4±12.6 months. At baseline, ILD was frequent (29.5%), while ILD-PH and PAH had lower prevalences (7.5%, 6.1%). At the end of follow up, 32% of SSc pts had ILD, 13% ILD-PH and 7% PAH. ILD and ILD-PH were more frequent in the diffuse form (47%, 12%), while PAH did not differ between subforms. Significant differences in baseline characteristics between PAH vs. ILD-PH vs. ILD were found for age (62, 59, 54 years), sex (males: 15%, 22%, 24%) and smoking prevalence (non-smokers 49%, 63%, 57%). Mean DLCO and FVC were 56%/93% for PAH, 49%/78% for ILD-PH and 56%/81% for ILD. Significant decreases for DLCO (≥15%) and FVC (≥10%) were found in 45%/26% in PAH, 45%/26% for ILD-PH and 36%/16% in ILD. All-cause mortality was 8.1% for the total cohort and differed significantly between patients without pulmonary involvement (4%), ILD (7.8%), PAH (14.2%), and ILD-PH (21%, p Conclusion ILD is the most prevalent pulmonary involvement in SSc, while PH-ILD is associated with the most detrimental survival. Significant differences in baseline characteristics of types of pulmonary SSc involvement may help to identify patients at risk in the future.

ObjectivesTo investigate the influence of vasodilator drugs on the occurrence of features depending on myocardial ischaemia/fibrosis (ventricular arrhythmias, Q waves, cardiac blocks, pacemaker implantation, left ventricular ejection fraction (LVEF) Methods601 patients with SSc were enrolled from 1 December 2012 to 30 November 2015 and had a second visit 0.5–4 years apart. 153 received no vasodilators; 448 received vasodilator therapy (ie, calcium channel blockers and/or ACE inhibitors or angiotensin II receptor blockers or combinations of them), 89 of them being also treated with either endothelin receptor antagonists or PDE5 inhibitors or prostanoids. Associations between the occurrence of myocardial disease manifestations and any demographic, disease and therapeutic aspect were investigated by Cox regression analysis. A Cox frailty survival model with centre of enrolment as random effect was performed.ResultsDuring 914 follow-up patient-years, 12 ventricular arrhythmias, 5 Q waves, 40 cardiac blocks, 6 pacemaker implantations and 19 reduced LVEF and/or congestive heart failure (CHF) occurred. In multivariate Cox regression analysis, vasodilator therapy was associated with a lower incidence of ventricular arrhythmias (p=0.03); low-dose acetylsalicylic acid (ASA) with a lower incidence of cardiac blocks and/or Q waves and/or pacemaker implantation (p=0.02); active disease with a higher incidence of LVEF ConclusionsThe present study might suggest a preventative effect on the occurrence of distinct myocardial manifestations by vasodilator therapy and low-dose ASA.

Background:Elderly rheumatoid arthritis (RA) patients are generally at increased risk of serious infections (SI). At the same time, treatment with bDMARDs has been associated with a higher SI risk than treatment with csDMARDs (1). However, long-term use of bDMARDs did not increase the risk of SI in a small group of elderly patients over 65 (2). The extent to which elderly patients are exposed to a higher SI risk when treated with JAK inhibitors (JAKi) is an open question.Objectives:To assess the effects of bDMARDs and specifically JAKi on the risk of SI in elderly patients with RA.Methods:The German register RABBIT is a prospective, longitudinally followed cohort of RA patients enrolled with a new start of a DMARD after at least one csDMARD failure. This analysis comprises patients over 70 years of age who were enrolled between 01/2007 and 04/2020 and had at least one follow-up.Results:Of 13,491 patients followed-up in RABBIT, 2274 with an age > 70 years were included in the analysis. 626 SI were observed in 425 of these patients. Baseline characteristics at start of the respective DMARD are shown in Table 1. In most characteristics, patients on JAKi were more comparable to patients under bDMARDs than to those on csDMARDs. JAKi patients received glucocorticoids (GC) less frequently than patients on other treatments. The HR for SI was lower than 1 in patients receiving bDMARDs or JAKi compared to csDMARDs, but without statistical significance (Figure 1). GC use (HR 1.6, 95% CI: 1.2 – 2.2 for ≤ 10 mg/d), higher DAS28-ESR values (HR 1.1, 95% CI: 1.0 – 1.2 per 1 point increase), COPD or pulmonary fibrosis (HR 1. 8, 95% CI: 1.3 – 2.4), chronic kidney disease (HR 1.5, 95% CI: 1.2 – 1.9) and diabetes mellitus (HR 1.3, 95% CI: 1.0 – 1.7) were associated with an increased risk of SI. Better physical capacity was associated with a decreased risk of SI (HR 0.9, 95% CI: 0.88 – 0.98 for a 10 point increase).Table 1.Patient characteristics by treatment at baselineParametercsDMARDsTNFiRTXABAIL-6iJAKiN=758N=840N=209N=147N=212N=108Age (years)75.9 (3.9)75.5 (3.6)74.8 (3.6)76.1 (3.9)75.9 (3.7)76.7 (3.7)Male sex184 (24.3)220 (26.2)50 (23.9)36 (24.5)46 (21.7)28 (25.9)Ever smoker249 (32.8)287 (34.2)77 (36.8)50 (34)73 (34.4)39 (36.1)Disease duration (years)7.9 (8.8)12.3 (11.4)17 (11.1)12.8 (10)13.8 (11.7)11.9 (10.9)Seropositivity487 (64.3)671 (79.9)201 (96.2)126 (85.4)182 (85.8)79 (73.5)Number of previous DMARDs1.4 (0.7)2.5 (1.3)4.2 (1.8)3.6 (1.9)3.3 (1.8)2.6 (1.5)DAS28-ESR4.6 (1.2)5.1 (1.2)5.4 (1.3)5.3 (1.3)5.3 (1.3)5 (1.2)Proportion of full physical function64.8 (23.1)57.1 (23.6)50.4 (23.7)52.9 (23.5)55.3 (24.1)55.2 (23.7)Number of comorbidities3.1 (2.5)3.8 (2.6)4.2 (2.6)4.6 (2.9)3.6 (2.4)3.8 (2.2)No comorbidity52 (6.9)29 (3.5)4 (1.9)4 (2.7)9 (4.2)5 (4.6)Three and more comorbidities385 (50.8)528 (62.9)147 (70.3)107 (72.8)131 (61.8)76 (70.4)COPD or pulmonary fibrosis69 (9.1)89 (10.6)29 (13.9)26 (17.7)12 (5.7)11 (10.2)Chronic kidney disease94 (12.4)151 (18)28 (13.4)21 (14.3)39 (18.4)22 (20.4)Diabetes mellitus151 (19.9)172 (20.5)31 (14.8)23 (15.6)42 (19.8)25 (23.1)GCs (last 6 months)347 (45.8)526 (62.6)143 (68.8)82 (56.2)127 (59.9)44 (40.7)GCs (447 (58.9)384 (45.7)101 (48.2)88 (60)118 (55.8)72 (66.7)GCs (5-9mg)252 (33.3)375 (44.6)81 (38.7)43 (29)72 (34.2)27 (25.1)GCs (>=10mg)59 (7.8)82 (9.8)274 (13.1)16 (11)21 (10)9 (8.2)Results are presented as mean ± SD for continuous variables and number (percentage) for discrete variables.Figure 1.Hazard ratios for serious infections with 95% confidence intervalsConclusion:Treatment with JAKi as well as treatment with bDMARDs was not associated with an increased risk of SI in elderly patients above 70 years of age.

Background:The current pandemic constitutes an entirely new situation for patients as well as physicians. The insecurity of the early phase, shutdowns, increasing infection rate and appearing SARS-CoV2 mutations have created a situation that makes live difficult especially for chronic diseases i.e. patients with rheumatic and musculoskeletal diseases (RMD) and their treating physicians. The psychosocial burden that is created by this special situation is completely unknown and is estimated to be higher in patients than in the general population.Objectives:In order to measure the impact on our patients, the German COVID19-Rheuma patient survey was set up in April 2020, during Germany’s first shut down.Methods:The German COVID19-Rheuma patient survey is a patient reported longitudinal online survey where patients with RMD who registered between April and July 2020 are asked on a monthly base using an online survey on social, personal, medical factors, whether a COVID19 infection occurred, isolation measures were changed and scores regarding stress and anxiety are recorded. Between April and July 2020, 637 patients registered and completed a first survey. Up to January 2021, about 400 patients are still enrolled.Here we present an interim analysis of the first 6 months regarding patients that were enrolled in April and May during the first shut-down. This first analysis compares the situation in the first lockdown to July, a phase with very low infection numbers in Germany, and to November, the beginning of the second lockdown.Results:150 patients (87% female) were enrolled in April/early May 2020. Mean age was 48 years (range 11-89). The majority of patients suffered from rheumatoid arthritis (51%), followed by psoriatic arthritis (17%), other spondyloarthropathies (10%) and connective tissue diseases (10%).The majority of patients received antirheumatic therapies: 32% glucocorticoids (GC), 31% cDMARDs, 21% TNF inhibitors, 7% Jak inhibitors, and 9% other biologicals. Of the patients treated with GC, 25% were on GC monotherapy.In the first lockdown, 26% of patients were working remotely and 24% were self-isolating (doubles included). Additionally, 48% were using masks that were not mandatory at that time and 41% were using disinfection in a regular manner. The rates for remote work and self-isolation did not change significantly over time while the mask use increased to 98% with the official obligation to do so. The use of disinfectants increased to 88% in November.Regarding disease activity, no change in patient global assessment could be observed over time (4.3 ± 2.5 vs. 4.0 ±2.6 and 4.0 ± 2.5). Self-reported pain was also stable over time as were sleep disturbances. While 48.2% of patients who were receiving physiotherapy paused in April, only 10 and 14% did so in July and November, respectively. 11% of the patients paused their medication in the first lockdown, whereas only 2.75% did so in July and 3.4% in November. Contact with the treating rheumatologist was maintained over time in the majority of cases.Conclusion:While in the beginning of the pandemic the insecurity was considerable and the concern that the fear for infection would lead to inadequately treated patients with RMDs, we here show for the first time that on the one hand our patients were timely in taking adequate measures to keep themselves safe (e.g. self-isolating, mask use) and adapted to the clinical situation in not pausing their medication. Altogether, in this alert cohort, the pandemic did not lead to an increase of patient-reported disease activity in the first six months.Acknowledgements:Thanks goes to all patients who participated in the study.Disclosure of Interests:None declared

Background:Gastroesophageal reflux disease (GERD) occurs frequently in patients with systemic sclerosis (SSc) and SSc-associated interstitial lung disease (SSc-ILD). PPI use has to been shown to improve survival in patients with idiopathic pulmonary fibrosis, whereas to date there are no data on the use of PPI in SSc-ILD.Objectives:This study was aimed to assess whether use of PPI is associated with progression of SSc-ILD and survival.Methods:We retrospectively analysed 1931 patients with SSc and SSc-ILD from the German Network for Systemic Sclerosis (DNSS) database (2003 onwards). Kaplan–Meier analysis compared overall survival (OS) and progression-free survival (PFS) in patients with vs. without GERD (SSc and SSc-ILD), and PPI vs. no PPI use (SSc-ILD only). Progression was defined as a decrease in either % predicted forced vital capacity ≥10% or single-breath diffusing capacity for carbon monoxide ≥15%, or death.Results:GERD was not associated with decreased OS or PFS in patients with either SSc or SSc-ILD. In patients with SSc-ILD, PPI use was associated with improved OS vs. no PPI use after 1 year (98.4% [95% confidence interval: 97.6–99.3]; n=760 vs. 90.8% [87.9–93.8]; n=290) and after 5 years (91.4% [89.2–93.8]; n=357 vs. 70.9% [65.2–77.1]; n=106; pConclusion:GERD had no effect on survival in SSc or SSc-ILD. PPIs improved survival in patients with SSc-ILD; however, controlled, prospective trials are needed to confirm this finding.Disclosure of Interests:Michael Kreuter Speakers bureau: Boehringer, Consultant of: Boehringer, Grant/research support from: Boehringer, Francesco Bonella Speakers bureau: Boehringer, Roche, GSK, Consultant of: Boehringer, Roche, GSK, Grant/research support from: Boehringer, Kuhr Kathrin: None declared, Jörg Henes Speakers bureau: Abbvie, Boehringer, Chugai, Roche, Janssen, Novartis, SOBI, Pfizer and UCB, Consultant of: Boehringer, Celgene, Chugai, Roche, Janssen, Novartis, SOBI, Grant/research support from: Chugai, Roche, Janssen, Novartis, SOBI, Pfizer, Elise Siegert: None declared, Gabriela Riemekasten Speakers bureau: Novartis, Janssen, Roche, GSK, Boehringer, Consultant of: Janssen, Actelion, Boehringer, Norbert Blank Consultant of: Sobi, Novartis, Roche, UCB, MSD, Pfizer, Actelion, Abbvie, Boehringer, Grant/research support from: Novartis, Sobi, Christiane Pfeiffer: None declared, Ulf Müller-Ladner: None declared, Alexander Kreuter Speakers bureau: MSD, Boehringer, InfectoPharm, Paid instructor for: MSD, PETER KORSTEN Consultant of: Glaxo, Abbvie, Pfizer, BMS, Chugai, Sanofi, Lilly, Boehringer, Novartis, Grant/research support from: Glaxo, Aaron Juche: None declared, Marc Schmalzing Speakers bureau: Chugai Roche, Boehringer, Celgene, Medac, UCB, Paid instructor for: Novartis, Abbvie, Astra Zeneca, Chugai Roche, Janssen, Consultant of: Chugai Roche, Hexal Sandoz, Gilead, Abbvie, Janssen, Boehringer, Margitta Worm Speakers bureau: Boehringer, Ilona Jandova Speakers bureau: Boehringer, Novartis, Abbvie, Laura Susok Speakers bureau: MSD, Novartis, BMS, Sunpharma, Consultant of: MSD, Tim Schmeiser Consultant of: Abbvie, Boehringer, Novartis, UCB, Claudia Guenther Paid instructor for: Advisory Board Boehringer January 2020, Employee of: Novartis 2002-2005, Gernot Keyszer Consultant of: Boehringer, Jan Ehrchen Speakers bureau: Boehringer, Janssen, Chugai, Sobi, Employee of: Pfizer, Actelion (now Janssen), Andreas Ramming Speakers bureau: Boehringer, Gilead, Janssen, Pfizer, Roche, Consultant of: Boehringer, Pfizer, Grant/research support from: Novartis, Pfizer, Ina Kötter Speakers bureau: several companies, Consultant of: several companies, Grant/research support from: several companies, Hanns-Martin Lorenz Speakers bureau: Abbvie, Astra Zeneca, Actelion, Alexion Amgen, Bayer Vital, Baxter, Biogen, Boehringer, BMS, Celgene, Fresenius, Genzyme, GSK, Gilead, Hexal, Janssen, Lilly, Medac, MSD, Mundipharm, Mylan, Novartis, Octapharm, Pfizer, Roche Chugai, Sandoz, Sanofi, Shire SOBI, Thermo Fischer, UCB, Grant/research support from: basic research studies: Pfizer, Novartis, Abbvie, Gilead, Lilly, MSD, Roche Chugai, Pia Moinzadeh Speakers bureau: Boehringer, Actelion, Grant/research support from: Actelion, Nicolas Hunzelmann Speakers bureau: Boehringer Janssen, Roche, Sanofi, Consultant of: Boehringer

Background:Gastroesophageal reflux (GER) is common in SSc and thus treatment with anti-acid therapy (AAT) is frequent. An association between GER and the development / progression of SSc-ILD has been hypothesized. However, outcomes of AAT on disease progression in SSc-ILD has only sparsely been studied.Objectives:Methods:The German Network for Systemic Scleroderma (DNSS), which includes SSc pts. prospectively, was analyzed for SSc-ILD. Those without progression at ILD 1stdiagnosis were categorized in AAT vs. no-AAT users and disease outcome was assessed.Results:SSc-ILD was reported in 1165 (28.2%) out of 4131 pts. 712 of SSc-ILD pts had no disease progression at ILD 1stdiagnosis. 567 used AAT while 145 did not. Baseline characteristics were similar between groups with regards to age (mean 54.7 years), BMI, time since SSc diagnosis and immunosuppressant use. Significant differences in no-AAT vs. AAT were found for gender (male 18% vs. 25%, p=0.05), SSc subtype (p=0.002, diffuse more common in AAT), lung function (DLCO 66% vs. 58%, p=0.001; FVC 86% vs. 77%, p=0.001), mRSS (8 vs. 11.5, pConclusion:While results may have partially been biased by differences in baseline characteristics, this current analysis disfavors the approach of AAT use for SSc-ILD.Disclosure of Interests:Michael Kreuter Grant/research support from: Roche, Boehringer, Consultant of: Roche, Boehringer, Speakers bureau: Boehringer, Roche, Francesco Bonella Grant/research support from: Boehringer, Consultant of: Boehringer, Roche, Bristol MS, Galapagos, Speakers bureau: Boehringer, Roche, Gabriela Riemekasten Consultant of: Cell Trend GmbH, Janssen, Actelion, Boehringer Ingelheim, Speakers bureau: Actelion, Novartis, Janssen, Roche, GlaxoSmithKline, Boehringer Ingelheim, Pfizer, Ulf Müller-Ladner Speakers bureau: Biogen, Jörg Henes Grant/research support from: Novartis, Roche-Chugai, Consultant of: Novartis, Roche, Celgene, Pfizer, Abbvie, Sanofi, Boehringer-Ingelheim,, Elise Siegert Grant/research support from: Actelion, Consultant of: AEC, Speakers bureau: NA, Claudia Guenther: None declared, Ina Koetter Grant/research support from: Novartis, Roche, Speakers bureau: Abbvie, Actelion, Celgene, MSD, UCB, Sanofi, Lilly, Pfizer, Novartis, Chugai, Roche, Boehringer, Norbert Blank Speakers bureau: Actelion, Roche, Boehringer, Pfizer, Chugai, Christiane Pfeiffer: None declared, Marc Schmalzing: None declared, Gabriele Zeidler: None declared, PETER KORSTEN Grant/research support from: Novartis, Juarms GmbH, Consultant of: Abbvie, Pfizer, Lilly, BMS, Speakers bureau: Abbvie, Pfizer, chugai, BMS, Lilly, Sanofi aventis, Laura Susok: None declared, Aaron Juche: None declared, Margitta Worm Consultant of: Mylan Gemany, Bencard Allergie, BBV Technologies S.A., Novartis, Biotest, Sanofi, Aimmune Therapies, Regeneron, Speakers bureau: ALK-Abello, Novartis, Sanofi, Biotest, Mylan, Actelion, HAL Allergie, Aimmune Bencard Allergie, Ilona Jandova: None declared, Jan Ehrchen: None declared, Cord Sunderkoetter: None declared, Gernot Keyszer: None declared, Andreas Ramming Grant/research support from: Pfizer, Novartis, Consultant of: Boehringer Ingelheim, Novartis, Gilead, Pfizer, Speakers bureau: Boehringer Ingelheim, Roche, Janssen, Tim Schmeiser Speakers bureau: Actelion, UCB, Pfizer, Alexander Kreuter Speakers bureau: Sanofi, Abbvie, Merck Sharp&Dohme, Boehringer, Kathrin Kuhr: None declared, Hanns-Martin Lorenz Grant/research support from: Consultancy and/or speaker fees and/or travel reimbursements: Abbvie, MSD, BMS, Pfizer, Celgene, Medac, GSK, Roche, Chugai, Novartis, UCB, Janssen-Cilag, Astra-Zeneca, Lilly.

Whipple's disease (WD) is a rare, chronic multiorgan disease which can caused by Tropheryma whipplei, a ubiquitous gram positive bacterium. Detection of T. whipplei is mostly performed histologically using periodic acid-Schiff (PAS) staining in affected tissues to visualize characteristic PAS-positive macrophages and by the polymerase chain reaction (PCR). Clinically, WD is often characterized by gastrointestinal symptoms (diarrhea, colic-like abdominal pain and weight loss). Arthritis is a common presentation of WS, often leading to a misdiagnosis of seronegative rheumatoid arthritis and as a consequence to immunosuppressive therapy. The clinical presentation of WD is highly polymorphic affecting different organ systems (e. g. cardiac or neurological manifestation) and making an appropriate clinical diagnosis and even the diagnostic process itself difficult. This article reports on three cases presenting with completely different leading symptoms (initially misdiagnosed as seronegative rheumatoid arthritis, spondyloarthritis and adult onset of Still's disease, respectively) that illustrate the rich diversity of WD. The cases were chosen to draw attention to the fact that although WD is mainly associated with the field of gastroenterology and gastrointestinal (GI) involvement is common, it may appear without GI symptoms. In cases of a clinical suspicion of WD, diagnostic efforts should be made to detect the bacterium in the affected organ. The German S2k guidelines on GI infections and WD published in January 2015 summarized the current state of the art for WD. The currently recommended primary treatment is antibiotics that can infiltrate the cerebrospinal fluid, e. g. ceftriaxone, followed by cotrimoxazole, which should be maintained over several months.

To determine the type and frequency of physical therapy (PT) prescribed by physicians for patients in the registry of the German Network for Systemic Sclerosis.The data for 4,252 patients were analyzed using descriptive statistics, chi-square tests, and odds ratios (ORs).Overall, 37.4% of patients (1,590 of 4,252) received PT at the end of a yearly follow-up. The most frequently used type of PT was lymphatic drainage (n = 1,061, 36.8%), followed by exercise therapy (n = 1,047, 36.3%) and heat therapy (n = 689, 23.9%). More than three-fourths of treated patients (82%) received 1 or 2 different forms of PT simultaneously. The prescription of PT was associated with the extent of skin fibrosis as measured by the modified Rodnan skin thickness score (10 [41.8% of patients], 11-20 [55.8% of patients], and21 [63.9% of patients]; P0.001). Patients with musculoskeletal involvement (e.g., arthritis, muscle weakness, joint contractures, tendon friction rubs) had a higher chance of receiving PT than patients without these symptoms, with corresponding ORs ranging from 1.96 (95% confidence interval [95% CI] 1.69-2.28) for joint contractures to 3.83 (95% CI 2.89-5.08) for arthritis. When comparing the type of PT prescription across the initial and all follow-up visits from 2003 to 2017, significant alterations with a decreasing frequency of patients receiving PT could be observed (P = 0.001).To our knowledge, this is the first study reporting the use of PT in patients with systemic sclerosis (SSc) in a large cohort. Although SSc is characterized by considerable disability and restriction of motion,40% of patients received PT.

Background Systemic sclerosis (SSc) is a very heterogeneous multisystem connective tissue disease. The majority of affected patients develop initial clinical symptoms between the age of 30 to 50 years. It is not known whether an ageing population affects the clinical phenotype of SSc. Objectives To investigate the relationship of the age at disease onset and clinical characteristics in SSc patients using the registry of the German Network for Systemic Scleroderma. Methods Clinical data of the patient registry, currently including 4021 patients, were evaluated. Three age ranges at disease onset ( 60 years) were correlated with clinical characteristics. Results Among all SSc patients, 27% of patients developed first non-raynaud symptoms at the age 60 years developed significantly (p Conclusions In this registry, nearly one third of patients developed SSc at an age above 60 years. These are mostly of the limited cutanous subtype with frequent PH. These findings have an important influence on recommendations on diagnosis and theray of SSC. Disclosure of Interest None declared

Background: Pulmonary involvement is the leading cause of death in SSc and can manifest as interstitial lung disease (ILD), pulmonary hypertension (PAH) or a combination (ILD-PH). Aim of this analysis was to determine prevalence, clinical characteristics and outcomes of these different forms within the German SSc Network. Methods: SSc pts were analyzed for pulmonary involvement, clinical characteristics and outcome. Results: There were 3699 pts in 42 centers with a mean follow up time of 34.4±12.6 months. At baseline, ILD was frequent (29.5%), while ILD-PH and PAH had lower prevalence (7.5%, 6.1%). At the end of follow up, 32% of SSc pts had ILD, 13% ILD-PH and 7% PAH. ILD and ILD-PH were more frequent in the diffuse form (47%, 12%), while PAH did not differ between subforms. Significant differences in baseline characteristics between PAH vs. ILD-PH vs. ILD were found for age (62, 59, 54 years), sex (males: 15%, 22%, 24%) and smoking prevalence (non-smokers 49%, 63%, 57%). Mean DLCO and FVC were 56% / 93 % for PAH, 49% / 78% for ILD-PH and 56% / 81% for ILD. Significant decreases for DLCO (≥15%) and FVC (≥10%) were found in 45% / 26% in PAH, 45% / 26% for ILD-PH and 36% / 16% in ILD. All-cause mortality was 8.1% for the total cohort and differed significantly between patients without pulmonary involvement (4%), ILD (7.8%), PAH (14.2%), and ILD-PH (21%, p Conclusions: ILD is the most prevalent pulmonary involvement in SSc, while PH-ILD is associated with the most detrimental survival. Significant differences in baseline characteristics of types of pulmonary SSc involvement may help identify patients at risk in the future.

Background: Interstitial lung disease (ILD) is common in patients with systemic sclerosis (SSc), significantly limiting quality of life and survival. Data on clinical correlations between lung function, SSc phenotypes and early diagnosis of pulmonary involvement are sparse. Methods: SSc patients within the German Network for Systemic Scleroderma were analyzed for the relationship of DLCO and clinical characteristics at baseline and follow up. Results: DLCO measurements were available for 1917 SSc patients with a total of 5597 clinical visits. At baseline, 64% of the patients had DLCO levels Conclusions: Impairment of DLCO is more common and more pronounced in patients with dcSSc and SSc-Overlap Syndrome compared to lcSSc. DLCO alone may be useful for diagnosing and monitoring pulmonary involvement in SSc.

Background Systemic sclerosis (SSc) is a chronic fibrosing autoimmune disease which leads to severe musculoskeletal dysfunction, disability and contractures. Little is known on the type and extent of physical therapy (PT) prescribed to SSc patients in daily practice. Objectives To determine the type and frequency of PT received by SSc patients. Methods The data of 3430 clinically well defined SSc patients registered in the database of the German Network for Systemic Sclerosis were analyzed using SPSS. Results 48,5% (1662/3430) of the patients were treated with PT. The most frequently used form of PT was lymphatic drainage (23,6%/876), followed by physical exercise therapy (22%/817) and paraffin wax bath (10,5%/389). About half of the patients (46,9%) received two or three different forms of PT simultaneously. The prescription of PT did not correlate with the SSc subtype, as 49,5% (503/1016) of dcSSc patients, 50,3% (850/1689) of lcSSc patients and 45,7% (143/313) of SSc-Overlap patients received PT. PT was significantly more often prescribed to patients with pulmonary fibrosis in 51,1% (617/1208), synovitis in 61,6% (299/485) and CK elevation in 61,1% (174/285) (p=0,001–0,029). PT did not correlate with the extent of skin fibrosis as measured by mRSS. Interestingly, patients with joint contractures (45,5%) (388/853) or tendon friction rubs (40,6%) (114/281) received significantly less often PT (p=0,006/ 0,045). Comparing the prescription of PT during the initial period 2003–2008 (49,1%; 1937/3942) with the follow up period 2009–2013 (45,3%; 2217/4899), a significant decrease of PT prescription was observed (p Conclusions Although SSc is characterized by considerable disability and restriction of motion, less than 50% of patients received PT. The significant decrease in PT prescription during recent years may reflect lack of knowledge how to prescribe PT and more restrictive insurance regulations. Disclosure of Interest None declared

Background Lung involvement, i.e. interstitial lung disease (ILD) and pulmonary hypertension (PH), is common in patients with systemic sclerosis (SSc), significantly limiting quality of life and survival. Data on clinical correlations between lung function and clinical subsets of SSc are sparse. Objectives To investigate the relationship of DLCO and clinical characteristics in patients SSc patients within the registry of the German Network for Systemic Scleroderma. Methods Clinical data of the patient registry, currently including DLCO data of 1917 patients were evaluated. In total, these patients were clinically evaluated 5997 times (i.e., at the first visit and during follow-up visits). At the initial visit and during follow-up DLCO levels were correlated with clinical characteristics. Results At initial presentation, 64% of the patients had DLCO levels CI 1.7–2.5) and SSc-Overlap patients (OR, 1.55; p Conclusions Impairment of pulmonary function as determined by diffusing capacity DLCO is more common and more pronounced in patients with dcSSc and SSc-Overlap Syndrome compared to lcSSc. DLCO may be useful for diagnosing and monitoring pulmonary involvement in SSc. Disclosure of Interest None declared

Objectives: The multisystem manifestations of SSc can greatly impact patients' quality of life. The aim of this study was to identify factors associated with disability in SSc. Methods: SSc patients from the prospective DeSScipher cohort who had completed the scleroderma health assessment questionnaire (SHAQ), a disability score that combines the health assessment questionnaire and five visual analogue scales, were included in this analysis. The effect of factors possibly associated with disability was analysed with multiple linear regressions. Results: The mean SHAQ and HAQ scores of the 944 patients included were 0.87 ( s . d . = 0.66) and 0.92 ( s . d . = 0.78); 59% of the patients were in the mild to moderate difficulty SHAQ category (0 ⩽ SHAQ < 1), 34% in the moderate to severe disability category (1 ⩽ SHAQ < 2) and 7% in the severe to very severe disability category (2 ⩽ SHAQ ⩽ 3). The means of the visual analogue scales scores were in order of magnitude: overall disease severity (37 mm), RP (31 mm), pulmonary symptoms (24 mm), gastrointestinal symptoms (20 mm) and digital ulcers (19 mm). In multiple regression, the main factors associated with high SHAQ scores were the presence of dyspnoea [modified New York Heart Association (NYHA) class IV (regression coefficient B = 0.62), modified NYHA class III (B = 0.53) and modified NYHA class II (B = 0.21; all vs modified NYHA class I)], FM (B = 0.37), muscle weakness (B = 0.27), digital ulcers (B = 0.20) and gastrointestinal symptoms (oesophageal symptoms, B = 0.16; stomach symptoms, B = 0.15; intestinal symptoms, B = 0.15). Conclusion: SSc patients perceive dyspnoea, pain, digital ulcers, muscle weakness and gastrointestinal symptoms as the main factors driving their level of disability, unlike physicians who emphasize objective measures of disability.

Mit Certolizumab pegol (CDP870) steht seit Oktober 2009 ein neuer TNF-α-Blocker zur Behandlung der rheumatoiden Arthritis zur Verfugung. Durch eine Modifizierung des Antikorperfragments durch das Anhangen von Polyethylenglykol (PEG) konnte im Tierversuch ein besseres Eindringen in entzundliches Gewebe nachgewiesen werden. In zwei individuellen Patientenkasuistiken konnte bei therapierefraktaren Arthritiden eine Remission unter dem pegylierten Certolizumab erreicht werden.

44 patients underwent bone marrow transplantation (BMT) for treatment of severe aplastic anaemia or haematological malignancies. During their post-transplant phase all patients had erythroblasts and granulocytic precursors in their peripheral blood. 15 patients died between day +6 and +346 after BMT and autopsies were performed. The sections of all 15 patients revealed extramedullary haemopoiesis in the spleen. Extramedullary haemopoiesis in the liver was found only in those patients who died early (between d +6 and d +21 after BMT). Medullary haemopoiesis, normally only occurring in the vertebral body, was also observed in the shaft of the femur. The present data show that after BMT all tissues with a haemopoietic matrix in ontogenesis can be repopulated with haemopoiesis in the early phase of reconstitution, possibly to compensate for the haemopoietic insufficiency after conditioning therapy. The expansion of haemopoiesis in the later period of up to 1 year after BMT, remains to be explained.

Graft-versus-host disease (GvHD) prophylaxis using methotrexate (23 patients) and T-cell depletion of the graft (40 patients) was compared in 63 allogeneic bone marrow transplantations (BMT) for leukaemia. T-cell depletion significantly reduced (p = 0.001) the incidence of GvHD from 68% to 11% and the GvHD-associated mortality from 79% to 5%. Actuarial disease-free survival for low-risk patients (57% with T-cell depletion and 47% with MTX) was not significantly improved, due to graft failure and possibly due to a higher leukaemic relapse rate after T-cell depletion. Prevention of graft failure after T cell-depleted BMT is essential and could also reduce the risk of leukaemic relapse by improved engraftment.

Objective Although gastrointestinal tract dysfunction is a common feature in patients with systemic sclerosis (SSc; scleroderma), few studies have addressed the pathogenetic mechanisms of gastrointestinal tract involvement in SSc. We previously showed that severe fibrosis and increased expression of profibrotic cytokines are important hallmarks in the gastric wall of patients with SSc. The aim of the present study was to investigate whether immune and/or microvascular abnormalities may account for tissue damage in gastric wall specimens obtained from patients with SSc. Methods Gastric biopsy samples from 27 patients with SSc and 15 healthy control subjects were analyzed by immunohistochemistry for CD45/leukocyte common antigen, CD3/T cells, CD4/T helper cells, CD8/cytotoxic T cells, CD20/B cells, CD14/monocytes, CD68/macrophages, cell adhesion molecules CD11a/lymphocyte function−associated antigen 1 (LFA-1), CD49d/very late activation antigen 4 (VLA-4), CD54/intercellular adhesion molecule 1 (ICAM-1), CD106/vascular cell adhesion molecule 1 (VCAM-1), CD31/platelet endothelial cell adhesion molecule 1, and vascular endothelial growth factor (VEGF). Results T cell infiltration was a prominent finding in gastric specimens from patients with SSc. The CD4+/CD8+ T cell ratio was significantly increased in SSc specimens compared with controls. T cells were found in both lymphocyte aggregates and diffuse infiltrates and strongly expressed the activation markers VLA-4, LFA-1, and ICAM-1. Endothelial cells showed corresponding surface activation with strong expression of VCAM-1 and ICAM-1. Mature B cells were frequently observed arranged in aggregates and rarely were seen in a diffuse pattern. Most lymphocyte aggregates lacked monocyte/macrophages. No difference in microvascular density was observed between SSc specimens and controls. Both SSc and control specimens showed weak or no expression of VEGF. Conclusion Our findings provide the first evidence that endothelial/lymphocyte activation leading to prominent CD4+ T cell infiltration may play a key pathogenetic role within the gastric wall of patients with SSc and may represent an important therapeutic target.

History and clinical findings A 53-year-old patient had a prosthetic valve (St. Jude Medical 25) 9 years ago because of a Staphylococcus aureus endocarditis with severe aortic regurgitation. An initially mild, progressively more severe, aortic regurgitation then developed as a result of an empty paravalvular abscess cavity, requiring another valve replacement. Fever started on the 3rd postoperative day and persisted despite combined treatment with beta-lactam antibiotics and aminoglycoside. Investigations At first no infectious focus could be identified radiologically or by echocardiography. But transoesophageal echocardiography revealed vegetations in the old abscess cavity. Several blood cultures were negative, while serological tests gave markedly raised antibody titers against Coxiella burnetii. Diagnosis, treatment and course Assuming Coxiella burnetii endocarditis the patient was given doxycycline, 2 x 100 mg daily and cotrimoxazole, 1 x 960 mg daily. The fever subsided and the vegetations had disappeared after four weeks. Because of the high risk of recurrence the antibiotic treatment was to be continued for two years. Conclusion Coxiella burnetii should be considered as a possible cause of fever of unknown origin, especially in patients with existing or operated cardiac valvar defects, when endocarditic vegetations have been demonstrated and several blood cultures have been negative.

Between April 1982 and December 1986, HLA-identical bone marrow transplantations were performed on 25 patients with Philadelphia chromosome-positive chronic myelocytic leukaemia (CML), 18 in the chronic phase, 7 in acceleration or blast crisis. Twelve of the 18 patients (67%) in the chronic phase are still alive a median period of 570 days after transplantation, but only two of the seven (29%) in acceleration or blast crisis a median period of 227 days after transplantation (P less than 0.025). The duration of the chronic phase was of great importance for survival after transplantation: 86% of patients in the chronic phase for less than two years survived, but all patients in the chronic phase for over two years died (P less than 0.001). CML relapses occurred in one patient in a late chronic phase and in two in an advanced stage of the disease. These results confirm the unfavorable outcome of bone marrow transplantation in the accelerated phase or blast crisis, as well as in the late chronic phase. Since at present there are no reliable risk factors for the occurrence of acceleration or blast crisis, bone marrow transplantation should be undertaken as early as possible in the chronic phase of CML.

HISTORY AND ADMISSION FINDINGS An 85-year-old woman was admitted because of frequent syncopes. She also reported slight weight loss, cough and dyspnoea. Chest auscultation revealed slight stridor and a cardiac arrhythmia, with an irregular ventricular rate between 120 and 140 beats/min. INVESTIGATIONS She had a thrombocytopenia (96 platelets/nl), and the ECG and long-term monitoring showed a tachyarrhythmia with atrial fibrillation, a bifascicular block (left anterior hemiblock and right bundle branch block), as well typical signs of sick-sinus syndrome with short periods of bradycardic sinus rhythm and pauses of up to 6 s on rhythm change. Echocardiography indicated moderately reduced left ventricular function. Chest radiogram revealed tracheal narrowing by a retrosternal goitre. No evidence of tumour was found on bronchoscopy. DIAGNOSIS, TREATMENT AND COURSE A VVI pacemaker was implanted. When the platelet count dropped to 30/nl idiopathic thrombocytopenic purpura was suspected, but administration of high doses of corticoids and immunoglobulin was without effect. Another echocardiogram, performed because of chest pain suspicious of pulmonary embolism, revealed a large bowl-shaped right ventricular thrombus with floating parts. Demonstration of anticardiolipin antibodies established the diagnosis of antiphospholipid syndrome (APLS), thought to be secondary to thyroid cancer suspected from the computed tomography. The patient died 2 months later from recurrent pulmonary embolism and progressive liver failure. Autopsy revealed a not previously diagnosed tracheal carcinoma with metastases to the thyroid, as well as haematogenous metastatic foci within the right ventricular thrombus. INTERPRETATION In case of thrombocytopenia of uncertain aetiology APLS should be included in the differential diagnosis, even in the absence of any early or acute thrombosis. If anticardiolipin antibodies and/or lupus anticoagulant are demonstrated, malignant neoplasm should be considered in addition to autoimmune disease.
