Obstetric medicine is an emerging area of interest within Internal Medicine in Europe. Despite that, "OM" is still an unpopular concept and an unrecognised subspecialty in South Europe. A considerable number of internists and medical specialists deal with maternal medical problems in association with obstetricians and other specialists on a daily basis. Due to their interest and mostly part-time dedication to maternal care, a growing mass of physicians are getting specific training in the field either locally or, less frequently, abroad, and are also building specific clinics, inpatient care services and other new bonds with obstetricians in numerous tertiary care centres. In this article, we aim to describe the state of the growing field of obstetric medicine in Portugal, Italy, France and Spain, the particular clinical, educational and academic efforts and steps that have recently been developed by internists in each country, as well as planned initiatives for the future.

Objectives: Primary Sjögren's syndrome (pSS) is one of the most common autoimmune diseases, mainly affecting women during the fourth decade of life. During pregnancy, the presence of anti-Ro/SSa and anti-La/SSb antibodies increases the risk of congenital heart block (CHB). Foetal and pregnancy outcomes in pregnant women with pSS compared with the general population are difficult to evaluate because of confounding factors including age and body mass index (BMI).Method: The aim of this case-control study was to analyse the impact of pSS in pregnant women on foetal and pregnancy outcomes.Results: We enrolled 19 women with pSS (54 pregnancies) matched by age and BMI to 216 controls. Patients with pSS delivered significantly earlier (38 weeks + 3 days vs. 39 weeks + 2 days) and experienced more spontaneous abortions [< 22 weeks of gestation (WG)] than the controls [n = 16/54 (30.0%) vs. n = 1/216 (0.4%); p < 0.00001]. Preterm delivery (≤ 37+6 WG) was significantly higher in the pSS group than in the control group (29% vs. 12%, p = 0.04). pSS activity significantly affected the birthweight percentile, which was lower in pregnancies occurring after the diagnosis of pSS than in those occurring before (32.43 ± 21.57 vs. 60.46 ± 27.37; p = 0.008). No case of CHB was observed.Conclusions: pSS is responsible for an increased risk of spontaneous abortion. The duration of pregnancy is lower in patients with than without pSS, with more premature deliveries. Pregnancies that occur after the onset of the disease result in lower birthweight percentile children than when pSS is not clinically overt. [ABSTRACT FROM AUTHOR]

Objectives: Previous studies have shown antiphospholipid antibodies (aPL) to be prevalent in primary systemic vasculitides; however, the possible clinical impact of aPL positivity in such patients has not been explored in depth. The aims of this study were to determine the prevalence of aPL in patients with Takayasu's arteritis (TA) and to ascertain whether aPL positivity was predictive of a worse clinical outcome in TA. Method: Clinical data were collected retrospectively on 22 TA patients over an 11-year period. Data collected included the presence of lupus anticoagulant (LA) and immunoglobulin (Ig)G and IgM anticardiolipin antibody (aCL) titres. Adverse clinical outcomes included cerebrovascular accident (CVA), transient ischaemic attack (TIA), loss of vision, vascular lesions (carotid, femoral, renal, coronary, or other vessels) requiring stenting, angioplasty, or other surgical intervention, aortic valve replacement, end-stage renal failure or death. Results: Persistently positive aPL or a concurrent diagnosis of antiphospholipid syndrome (APS) was found in 45% (n = 10) of TA patients while 55% (n = 12) had TA alone. LA was present in a significant proportion of TA patients with aPL (p = 0.002). Vascular complications occurred in 70% (n = 7) of TA patients with aPL and in 25% (n = 3) of TA patients without aPL (p = 0.035). LA was associated with a higher prevalence of vascular complications. Conclusions: Persistently positive aPL are present in a significant proportion of TA patients. This study shows that vascular complications and need for intervention are more prevalent in TA patients with aPL, particularly those with LA. Prospective studies are needed to determine the long term prognosis in such patients. [ABSTRACT FROM AUTHOR]

Résumé Introduction Les anomalies de l'hémostase chez le patient lupique sont majoritairement de nature thrombotique mais plus rarement hémorragique. Observation Nous rapportons le cas d'un homme de 25 ans présentant un syndrome d'activation macrophagique révélateur d'un lupus érythémateux systémique et compliqué secondairement d'un syndrome hémorragique avec un allongement du temps de thrombine et du temps de céphaline activée, corrigés in vitro par l'ajout de protamine, confirmant ainsi la présence d'un anticoagulant « héparine-like ». Le bilan d'hémostase s'est normalisé après traitement spécifique du lupus. Conclusion Cette anomalie rare du bilan d'hémostase est connue dans les hémopathies et cancers solides. Il s'agit de la première description au cours d'un lupus. Après un an de recul, aucun diagnostic d'hémopathie ou de néoplasie solide n'a été porté. Abstract Introduction In systemic lupus erythematosus, hemostasis disorders are mainly thrombotic, but more rarely hemorrhagic. Case report A 25-year-old man presented with a macrophagic activation syndrome revealing a systemic lupus erythematosus, secondarily complicated by a hemorrhagic syndrome ; biological investigations revealed an increase thrombin time and an activated partial thromboplastin time, normalized by protamin neutralization in vitro, thus confirming the presence of a heparin-like anticoagulant. The hemostasis balance normalized after the specific treatment of lupus. Conclusion This rare anomaly of hemostasis balance has been described in blood cancers and solid cancers. This is the first description of a case associated with an autoimmune connective tissue disorder such as lupus. After one year of follow-up, no diagnosis of blood or solid cancer was made.

Antiphospholipid syndrome (APS) is a chronic autoimmune disease involving vascular thrombosis and/or obstetric morbidity and persistent antibodies to phospholipids or certain phospholipid-associated proteins. It is a rare condition in adults and even rarer in children. The diagnosis of APS can be facilitated by the use of classification criteria based on a combination of clinical and biological features. APS may be rapidly progressive with multiple, often synchronous thromboses, resulting in life-threatening multiple organ failure. This form is known as "catastrophic antiphospholipid syndrome" (CAPS). It may be primary or associated with systemic lupus erythematosus (associated APS) and in very rare cases with other systemic autoimmune diseases. General practitioners and paediatricians may encounter APS in patients with one or more vascular thromboses. Because APS is so rare and difficult to diagnosis (risk of overdiagnosis) any suspected case should be confirmed rapidly and sometimes urgently by an APS specialist. First-line treatment of thrombotic events in APS includes heparin followed by long-term anticoagulation with a VKA, usually warfarin. Except in the specific case of stroke, anticoagulants should be started as early as possible. Any temporary discontinuation of anticoagulants is associated with a high risk of thrombosis in APS. A reference/competence centre specialised in autoimmune diseases must be urgently consulted for the therapeutic management of CAPS. [ABSTRACT FROM AUTHOR]

Introduction: Modifiable cardiovascular risk factors (CVRF) are highly prevalent in SubSaharan African communities. In these countries the burden of CVRF during early pregnancy has been poorly documented., Aim: The objective of this study was to describe the frequency of CVRF in pregnant women before the 20th week of gestation in Benin., Methods: Consecutive pregnant women with a gestational age < 20th week were included in 30 maternity clinics in Benin. Univariate and multivariate analyses were used to determine characteristics associated with CVRF., Results: 1244 pregnant women were included (680 (54.7%) in urban areas and 584 (45.3%) in rural areas). The median age was 26 years. The frequencies of high blood pressure (HBP), obesity and diabetes were 18.9%, 15.0% and 3.1% respectively. Very few women (25.3%) were aware of the HBP disorder. HBP was associated with an age ≥ 35 years (OR = 1.7, 95%CI:1.1-2.7), a rural setting (OR = 2.6; 95%CI:1.9-3.5), an insufficient consumption of fruits and vegetables (OR = 3.2; 95%CI:2.0-5.3) and a history of at least 2 fetal losses (OR = 1.9; 95% CI [1.4-2.7]). The risk of being overweight was associated with an age >24 years old (OR = 1.6; 95%CI:1.1-2.2) conversely a rural setting was protective (OR = 0.7; 95%CI:0.5-0.9). Obesity was associated with an age > 35 years old (OR = 4.1; 95%CI:2.5-6.8) and a rural setting (OR = 0.3; 95%CI: 0.2-0.5)., Conclusion: The frequency of CVRF in women before 20th week of gestation was high. Most of the women were unaware of the disorder. Thus the screening of CVRF among women of reproductive age might be relevant., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Tchibozo et al.

Objectives: Giant cell arteritis (GCA) often features upper respiratory tract (URT) and orofacial manifestations, which signal the involvement of external carotid artery branches. In this study, we aimed to describe the frequency of various URT/orofacial symptoms at GCA onset, as well as the main characteristics of patients presenting these symptoms., Methods: We included all patients who were newly diagnosed with GCA between 1976 and April 2022 at the Internal Medicine Department of a tertiary-care hospital. Ten URT or orofacial symptoms were prospectively examined systematically in each patient. We used multivariate analyses to identify the GCA characteristics, including URT/orofacial symptoms, associated with temporal artery biopsy (TAB) positivity., Results: At least 1 URT/orofacial symptom was present in 68.6% of the 599 patients (3 or more symptoms in 30% of cases). Jaw claudication, maxillary pain, and pain during mouth opening were the most prevalent symptoms. Dry cough was recorded in 17% of cases. GCA patients with URT/orofacial symptoms had more clinical abnormalities of the temporal artery bed and ischaemic ophthalmological complications, but less large-vessel vasculitis according to imaging. The likelihood of a positive TAB was increased in patients with an abnormal temporal artery upon clinical examination (OR 4.16; CI 2.75-6.37, p < 0.001) or jaw claudication (OR 2.18; CI 1.35-3.65, p = 0.002), and decreased in those with hoarseness (OR 0.47; CI 0.26-0.87, p = 0.02) or earache (OR 0.54; CI 0.31-0.95, p = 0.03). Isolated URT/orofacial presentation (i.e., without headache or visual signs) accounted for 5.2% of the entire cohort., Conclusions: Oral-facial symptoms were present in two-thirds of GCS cases. Thus, they could serve as leading clinical clues for a GCA diagnosis, and are a risk factor for permanent visual loss. Several URT/orofacial symptoms such as jaw claudication, hoarseness, and earache influenced the likelihood of a positive TAB. Isolated URT/orofacial presentation of GCA is a rare but potentially challenging occurrence.

Background: Complementary and alternative medicine (CAM) is composed of a wide range of interventions and frequently used in parallel with conventional medicine. The aim of this study was to assess the prevalence, modalities, and association factors of CAM utilization in patients treated for systemic lupus erythematosus, primary Sjögren's syndrome, or systemic sclerosis., Patients and Methods: This was a prospective single-center observational study conducted in a French university hospital center. Inclusion criteria were patients followed for systemic lupus erythematosus, primary Sjögren's syndrome, or systemic sclerosis. Data were collected with a survey which assessed sociodemographic, disease characteristics, CAM use details, life quality, and anxiety score., Results: A total of 121 patients were included, mostly women (87%), with an average age of 56 years. Proportion of patients seeking CAM was 55%. A total of 186 CAM interventions were recorded: most common were osteopathy, homeopathy, and acupuncture. Patients were looking for well-being (22%), reducing their fatigue (18%) and pain (33%). Concerning physical and mental feeling after CAM use, a subjective improvement was reported in 89% of cases. In multivariate analysis, CAM use by patient was associated with these 3 variables: coming from a Western culture, being professionally active, and having a poor quality of life and anxiety scores., Conclusion and Outlook: This is the first study to focus on CAM use in patients followed for three AID in a French rural region. The current challenge is to enrich conventional medicine with CAM that is effective and safe through supervised programs to move toward an integrative medicine., Die Komplementär- und Alternativmedizin (CAM) umfasst ein breites Spektrum an Interventionen und wird häufig parallel zur konventionellen Medizin angewendet. Das Ziel dieser Studie war die Beurteilung der Prävalenz, Modalitäten und Assoziationsfaktoren der CAM-Anwendung bei Patienten, die wegen systemischem Lupus erythematodes, primärem Sjögren-Syndrom oder systemischer Sklerose behandelt werden.Es handelte sich um eine prospektive monozentrische Beobachtungsstudie, die an einem französischen Universitätsklinikum durchgeführt wurde. Eingeschlossen wurden Patienten, die dort wegen systemischem Lupus erythematodes, primärem Sjögren-Syndrom oder systemischer Sklerose in Behandlung waren. Die Datenerhebung erfolgte mittels eines Fragebogens, der soziodemografische Merkmale, Krankheitsmerkmale, Einzelheiten der CAM-Anwendung, Lebensqualität- und Angst-Scores umfasste.Insgesamt wurden 121 Patienten randomisiert, überwiegend Frauen (87%); das Durchschnittsalter betrug 56 Jahre. Der Anteil der Patienten, die CAM wünschten, betrug 55%. Insgesamt 186 CAM-Interventionen wurden erfasst; am häufigsten Osteopathie, Homöopathie und Akupunktur. Den Patienten ging es dabei um das Wohlbefinden (22%) sowie die Linderung von Müdigkeit (18%) und Schmerzen (33%). Hinsichtlich des physischen und psychischen Befindens nach der CAM-Anwendung berichteten 89% der Befragten über eine subjektiv empfundene Verbesserung. In multivariaten Analysen war die CAM-Anwendung pro Patient mit den folgenden 3 Variablen assoziiert: aus einer westlichen Kultur stammend, berufstätig sowie schlechte Lebensqualität- und Angst-Scores.Dies ist die erste Studie zur CAM-Anwendung bei Patienten, die im ländlichen Raum in Frankreich wegen einer von drei Autoimmunerkrankungen behandelt werden. Die aktuelle Herausforderung lautet, der konventionellen Medizin in supervidierten Programmen wirksame und sichere CAM-Interventionen an die Seite zu stellen, um zu einer integrativen Medizin zu gelangen., (© 2024 S.

Introduction: Giant cell arteritis (GCA) is complicated in 10 to 20% of cases by permanent visual ischemia (PVI). International guidelines advocate the use of intravenous pulse of methylprednisolone from 250 to 1000mg per day, for three days, followed by oral prednisone at 1mg/kg per day. The aim of this study is to assess whether this strategy significantly reduces the risk of early PVI of the second eye, compared with direct prednisone at 1mg/kg per day., Methods: We conducted a multicentre retrospective observational study over the past 15 years in 13 French hospital centres. Inclusion criteria included: new case of GCA; strictly unilateral PVI, prednisone at dose greater than or equal to 0.9mg/kg per day; for the intravenous methylprednisolone (IV-MP) group, total dose between 900 and 5000mg, close follow-up and knowledge of visual status at 1 month of treatment, or earlier, in case of contralateral PVI. The groups were compared on demographic, clinical, biological, iconographic, and therapeutic parameters. Statistical analysis was optimised using propensity scores., Results: One hundred and sixteen patients were included, 86 in the IV-MP group and 30 in the direct prednisone group. One patient in the direct prednisone group and 13 in the IV-MP group bilateralised, without significant difference between the two strategies (3.3% vs 15.1%). Investigation of the association between IV-MP patients and contralateral PVI through classical logistic regression, matching or stratification on propensity score did not show a significant association. Weighting on propensity score shows a significant association between IV-MP patients and contralateral PVI (OR=12.9 [3.4; 94.3]; P<0.001). Improvement in visual acuity of the initially affected eye was not significantly associated with IV-MP (visual acuity difference 0.02 vs -0.28 LogMar), even in the case of early management, i.e., within the first 48hours after the onset of PVI (n=61; visual acuity difference -0.11 vs 0.25 LogMar). Complications attributable to corticosteroid therapy in the first month were significantly more frequent in the IV-MP group (31.8 vs 10.7%; P<0.05)., Discussion: Our data do not support the routine use of pulse IV-MP for GCA complicated by unilateral PVI to avoid bilateral ophthalmologic damage. It might be safer to not give pulse IV-MP to selected patients with high risks of glucocorticoids pulse side effects. A prospective randomised multicentre study comparing pulse IV-MP and prednisone at 1mg/kg per day is desirable., (Copyright © 2023 Société française de rhumatologie. Published by Elsevier Masson SAS.

Introduction: Biopsy-proven giant cell arteritis (GCA) occasionally presents without acute-phase reaction. In this setting, GCA may be initially overlooked and glucocorticoid treatment unduly delayed, potentially increasing ischemic risk., Patients and Methods: From an inception cohort of patients with newly diagnosed, biopsy-verified GCA, we retrieved all cases without elevation of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level before starting glucocorticoid treatment. We compared the baseline features and outcomes of these patients and two additional patients recruited after GCA diagnosis with those of 42 randomly selected patients with high baseline ESR and CRP., Results: Of 396 patients, 14 (3.5%) had lower baseline values of both ESR and CRP. Lower baseline ESR and CRP were associated with fewer American College of Rheumatology criteria met (p < 0.001, 95% CI - 1.1; - 0.9), and less jaw claudication (p = 0.06, 95% CI 0.8; 44.9), but similar rates of permanent blindness (p = 1.0). Patients with lower ESR and CRP also showed obvious differences regarding mean blood cell counts and mean hemoglobin level, but also less anti-cardiolipin antibody positivity (p = 0.04, 95% CI 0.8; ∞ ) and hepatic cholestasis (p = 0.03, 95% CI 1.0; 422). Patients with lower ESR and CRP had fewer GCA relapses (p = 0.03, 95% CI - 1.1; - 0.1), fewer glucocorticoid-induced complications (p = 0.01, 95% CI - 2.0; - 0.1), and successfully stopped glucocorticoids sooner than the other patients (18.3 months vs 34 months in average, p = 0.02, 95% CI - 27;- 0.9)., Conclusion: Biopsy-proven GCA presenting with lower ESR and CRP is not an exceptional occurrence. It is clinically less typical but carries similar ischemic risk to other forms of the disease. Conversely, the late GCA prognosis of these patients is excellent., (© 2023.

Background: The prevention of catastrophic antiphospholipid syndrome (CAPS), a rare complication of antiphospholipid syndrome (APS), is a major goal., Objectives: We analyzed its precipitating factors, focusing on anticoagulation immediately before CAPS episodes., Methods: We retrospectively analyzed patients in the French multicenter APS/systemic lupus erythematosus database with at least 1 CAPS episode. Then we compared each patient with known APS before CAPS with 2 patients with non-CAPS APS matched for age, sex, center, and APS phenotype., Results: We included 112 patients with CAPS (70% women; mean age, 43 ± 15 years). At least 1 standard precipitating factor of CAPS was observed for 67 patients (64%), which were mainly infections (n = 28, 27%), pregnancy (n = 23, 22%), and surgery (n = 16, 15%). Before the CAPS episode, 67 (60%) patients already had a diagnosis of APS. Of the 61 treated with anticoagulants, 32 (48%) received vitamin K antagonists (VKAs), 23 (34%) heparin, and 2 (3%) a direct oral anticoagulant. They were less likely than their matched patients with APS without CAPS to receive VKA (48% vs 66%, p = .001). Among those treated with VKA, 72% had a subtherapeutic international normalized ratio (ie, <2) versus 28% in patients with APS without CAPS (p < .001). Finally, excluding pregnant patients (n = 14) for whom we could not differentiate the effect of treatment from that of pregnancy, we were left with 47 cases, 32 (68%) of whom had recently begun a direct oral anticoagulant, planned bridging therapy, or had VKA treatment with international normalized ratio <2., Conclusion: These results strongly suggest that suboptimal anticoagulation management can trigger CAPS in patients with thrombotic APS., Competing Interests: Declaration of competing interests There are no competing interests to disclose., (Copyright © 2023 International Society on Thrombosis and Haemostasis.

The occurrence and course of immune-mediated diseases (IMDs) following COVID-19 vaccination has been little explored so far. We retrieved, among adult patients hospitalized at the Internal Department of a French university hospital up to May 2022, all those who had developed, or relapsed to, an IMD less than 3 weeks following COVID-19 vaccination, without other triggers. Twenty-seven (24 new-onset) post-COVID-19 vaccine IMDs were recorded. They comprised giant cell arteritis or polymyalgia rheumatica ( n = 16, HLA-DRB1*04 in 58% of 12 assessed GCA cases), immune-mediated necrotizing myositis or acute rhabdomyolysis, systemic vasculitis, immune thrombocytopenic purpura, rheumatoid arthritis, anti-synthetase syndrome, and adult-onset Still's disease. The causative vaccines were mRNA-based (20 cases) or viral vector-based (7 cases). The IMD typically occurred after the first vaccine dose, with an average delay of 8 (5 SD) days. The patients' mean age was 67 years, and 58% were women. The IMDs had protracted courses in all but three of the patients and typically required high-dose glucocorticoids, in combination with immunomodulators in 13 patients. One patient died of intractable rhabdomyolysis, whereas five suffered permanent damage from IMDs. Eleven patients with well-controlled IMDs completed their COVID-19 vaccination schedule, and two suffered mild IMD relapses. There is a risk of IMDs, notably GCA/PMR, and muscle disorders, following COVID-19 vaccination. Such adverse reactions typically occurred after the first dose, raising concern about subsequent COVID-19 vaccinations. However, early re-challenge in well-controlled IMDs appeared safe.

Background: Prospective data about the risks of thrombotic and severe haemorrhagic complications during pregnancy and post partum are unavailable for women with antiphospholipid syndrome. We aimed to assess thrombotic and haemorrhagic events in a prospective cohort of pregnant women with antiphospholipid syndrome., Methods: This multicentre, prospective, observational study was done at 76 centres in France. To be eligible for this study, women had to have diagnosis of antiphospholipid syndrome; have conceived before April 17, 2020; have an ongoing pregnancy that had reached 12 weeks of gestation; and be included in the study before 18 weeks of gestation. Exclusion criteria were active systemic lupus erythematosus nephropathy, or a multifetal pregnancy. Severe haemorrhage was defined as the need for red blood cell transfusion or maternal intensive care unit admission because of bleeding or invasive procedures, defined as interventional radiology or surgery, to control bleeding. The GR2 study is registered with ClinicalTrials.gov, NCT02450396., Findings: Between May 26, 2014, and April 17, 2020, 168 pregnancies in 27 centres met the inclusion criteria for the study. 89 (53%) of 168 women had a history of thrombosis. The median term at inclusion was 8 weeks gestation. 16 (10%) of 168 women (95%CI 5-15) had a thrombotic (six [4%] women; 95% CI 1-8) or severe haemorrhagic event (12 [7%] women; 95% CI 4-12). There were no deaths during the study. The main risk factors for thrombotic events were lupus anticoagulant positivity at inclusion (six [100%] of six women with thrombosis vs 78 [51%] of 152 of those with no thrombosis; p=0·030) and placental insufficiency (four [67%] of six women vs 28 [17%] of 162 women; p=0·013). The main risk factors for severe haemorrhagic events were pre-existing maternal hypertension (four [33%] of 12 women vs 11 [7%] of 156 women; p=0·014), lupus anticoagulant positivity at inclusion (12 [100%] of 12 women vs 72 [49%] of 146 women; p<0·0001) and during antiphospholipid history (12 [100%] of 12 women vs 104 [67%] of 156 women; p=0·019), triple antiphospholipid antibody positivity (eight [67%] of 12 women vs 36 [24%] of 147 women; p=0·0040), placental insufficiency (five [42%] of 12 women vs 27 [17%] of 156 women; p=0·038), and preterm delivery at 34 weeks or earlier (five [45%] of 11 women vs 12 [8%] of 145 women; p=0·0030)., Interpretation: Despite treatment adhering to international recommendations, a proportion of women with antiphospholipid syndrome developed a thrombotic or severe haemorrhagic complication related to pregnancy, most frequently in the post-partum period. Lupus anticoagulant and placental insufficiency were risk factors for these life-threatening complications. These complications are difficult to prevent, but knowledge of the antenatal characteristics associated with them should increase awareness and help physicians manage these high-risk pregnancies., Funding: Lupus France, association des Sclérodermiques de France, association Gougerot Sjögren, Association Francophone contre la Polychondrite chronique atrophiante, AFM-Telethon, the French Society of Internal Medicine and Rheumatology, Cochin Hospital, the French Health Ministry, FOREUM, the Association Prix Veronique Roualet, and UCB., Competing Interests: Declaration of interests NC-C has received an unrestricted research grant from UCB to her institution.

Objective: Stroke caused by giant cell arteritis (GCA) is a rare but devastating condition and early recognition is of critical importance. The features of GCA-related stroke were compared with those of GCA without stroke and atherosclerosis-related or embolic stroke with the aim of more readily diagnosing GCA., Methods: The study group consisted of 19 patients who experienced GCA-related strokes within an inception cohort (1982-2021) of GCA from the internal medicine department, and the control groups each consisted of 541 GCA patients without a stroke and 40 consecutive patients > 50 years of age with usual first ever stroke from the neurology department of a French university hospital. Clinical, laboratory, and imaging findings associated with GCA related-stroke were determined using logistic regression analyses. Early survival curves were estimated using the Kaplan-Meier method and compared using the log rank test., Results: Amongst 560 patients included in the inception cohort, 19 (3.4%) developed GCA-related stroke. GCA-related stroke patients had more comorbid conditions (p = 0.03) and aortitis on imaging (p = 0.02), but less headache (p < 0.01) and scalp tenderness (p = 0.01). Multivariate logistic regression analysis showed that absence of involvement of the anterior circulation (OR = 0.1 - CI: 0.01-0.5), external carotid ultrasound (ECU) abnormalities (OR = 8.1 - CI: 1.3-73.9), and C-reactive protein (CRP) levels > 3 mg/dL (OR = 15.4 - CI: 1.9-197.1) were independently associated with GCA-related stroke. Early survival of GCA-related stroke patients was significantly decreased compared with control stroke patients (p = 0.02) and GCA patients without stroke (p < 0.001)., Conclusions: The location of stroke and assessment of ECU results and CRP level could help improve the prognosis of GCA-related stroke by bringing this condition to the clinician's attention more quickly, thus shortening diagnostic delay., (Copyright © 2022.

Introduction: Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are inflammatory rheumatic diseases common in people over the age of 50 years. Seasonal influenza vaccination (IV) is strongly recommended in this population, among whom it is considered to be effective and well tolerated. IV-induced GCA or PMR are thought to be exceptional., Patients and Methods: We retrieved all post-IV cases from an inception cohort of patients with newly diagnosed GCA. We also included two patients with post-IV PMR and reviewed all published reports of post-IV GCA or PMR, with selection of cases demonstrating disease onset within 1 month following IV. We compared the results of HLA-DRB1 typing, performed in seven patients with post-IV GCA or PMR, with those of 11 GCA patients with familial aggregation and 16 randomly selected GCA patients without a reported trigger., Results: Of 358 GCA recruited since 2002, 10 (2.8%) qualified for post-IV GCA, of whom two also showed familial aggregation. Thirty-two patients (19 with GCA and 13 with PMR) including our patients were reviewed; their mean age was 71.8 ± 7.4 years and the M/F ratio was 0.8. Six patients (19%) had a history of PMR. Patients with post-IV GCA/PMR had the DRB1*13:01 haplotype more frequently compared to those with familial GCA (5/7 vs. 2/11, p = 0.048) or with GCA without a known trigger (3/16, p = 0.026). Post-IV PMR generally appeared self-limited, whereas post-IV GCA often displayed a more protracted course (chronic relapsing disease in one-third of the patients)., Conclusion: Post-IV onset of GCA/PMR is not an exceptional occurrence and may be part of the spectrum of the autoimmune syndrome induced by adjuvants (ASIA). IV can trigger GCA or PMR, especially in persons at higher spontaneous risk, such as those with a personal or familial history of GCA/PMR. Whether the presence of the DRB1*13:01 allele further increases the risk of post-IV GCA/PMR through a stronger vaccine-induced immune reaction deserves further investigation. Unlike PMR, GCA can be a serious complication of IV., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Background: Maternal mortality is a public health issue, particularly in low- and middle-income countries (LMIC). Sub-Saharan Africa (SSA) is the region most affected worldwide by maternal mortality, and preeclampsia is one of the main causes. We performed a systematic review of observational studies to identify the impact of cardiovascular risk factors on preeclampsia in SSA with a more representative sample., Methods: Databases: PubMed and Google Scholar were searched to identify published studies. Studies were included if they reported results on the link between at least one cardiovascular risk factor and preeclampsia. Relevant studies quality was assessed with the Newcastle-Ottawa Scale (NOS). Odds ratios and relative risk (RR) were reported with their confidence intervals., Results: Twelve articles (8 case-controls, 3 cohorts, 1 cross-sectional) were included in this review, with a total of 24,369 pregnant women. Cardiovascular risk factors such as chronic hypertension, overweight, obesity, diabetes and alcohol were significantly associated with a high risk of preeclampsia. Very few data were available concerning some risk factors. None of the articles reported tobacco consumption as a preeclampsia risk factor. There is a lack of data from French-speaking SSA countries., Conclusion: Cardiovascular risk factors increase the risk of preeclampsia. Our results suggest the need for prospective cohort studies to ascertain this association in order to reduce maternal mortality due to preeclampsia.

Background: Abdominal symptoms in patients with primary Sjögren syndrome (pSS) are poorly documented. The objective of the study was to describe the abdominal symptoms of patients with pSS and to assess their association with characteristics of the disease., Methods: One hundred and fifty patients with pSS were evaluated using a composite global symptom score for abdominal symptoms and their severity. Data concerning the clinical and biological characteristics of pSS and abdominal disorders were also collected., Results: Of the patients with pSS, 95% suffered from abdominal symptoms (median global symptom score 7.5 ± 5.5 points out of 30). More than half of the patients experienced abdominal tension (68%), upper abdominal pain (54%), abdominal discomfort (58%) and/or constipation (54%). Regarding the pSS activity, in relation to European League Against Rheumatism (EULAR) Sjögren syndrome disease activity index score items, general and central nervous system involvement wereassociated with a high global symptom score. The EULAR Sjogren Syndrome Patient Reported Index (ESSPRI) symptom score was positively correlated with the global symptom score (p < 0.01). Multivariate analysis showed a significant association between a high global symptom score and SSA seronegativity, gastroparesis, and ESSPRI score (p < 0.01 for each)., Conclusions: The majority of patients with pSS suffered abdominal symptoms. There is currently no therapeutic recommendation because of the lack of information on the underlying pathophysiological mechanisms., Trial Registration: NCT03157011 . Date of registration: July 17, 2017.

Background: Giant cell arteritis (GCA) is a disease that relapses often, and some patients run a refractory course. Although prompt recognition of resistant GCA is a major issue, there is no well-recognized, baseline risk factor for poor response to glucocorticoid (GC) treatment., Methods: We included all patients consecutively diagnosed with GCA and homogeneously treated since 1976 in a single department and regularly followed-up for at least 18 months. Using a set of customized criteria defining response to GCs, we separated patients into highly responsive, usually responsive, dependent on GCs, and resistant to GCs. We determined which of the baseline variables were associated with GC-resistance and conducted factor analyses of mixed data and decision tree analyses. We also determined whether being GC-resistant was associated with poorer tolerance to GCs and higher death rates., Results: In all, 455 patients were followed for 93.4 ± 67.6 (standard deviation) months; 41 (9%) and 21 (4.6%) patients developed GC-dependent and GC-resistant disease, respectively. Factor analyses suggested an association between clinical pattern and degree of responsiveness to GCs; The decision tree analyses, built on an age at GCA onset 〈 66 years and body weight 〉 71 kg, delineated a high risk profile (44% of the patients who featured both characteristics were GC-resistant vs. less than 3% who featured neither, p < 0.001). Infections were more prevalent in the GC-resistant or GC-dependent patients, but without decreasing their survival., Conclusion: Extra-cranial, large-vessel GCA may be associated with prolonged GC requirements. A simple combination of age and body weight defined a subgroup of patients at high risk for developing GC resistance. Our findings need confirmation in prospective controlled studies., Competing Interests: Declaration of Competing Interest None of the authors declare any conflicts of interest., (Copyright © 2020 Elsevier Inc.

Objective: To compare characteristics, pregnancies and treatments during pregnancies of seronegative and seropositive antiphospholipid syndrome (APS), to analyse factors associated with obstetrical outcome., Patients and Methods: Inclusion criteria were: (1) thrombotic and/or obstetrical APS (Sydney criteria); (2) absence of conventional antiphospholipid antibodies (APL); (3) at least one persistent non-conventional APL among IgA anticardiolipin antibodies, IgA anti-B2GPI, anti-vimentin G/M, anti-annexin V G/M, anti-phosphatidylethanolamine G/M and anti-phosphatidylserine/prothrombin G/M antibodies. The exclusion criteria were: (1) systemic lupus erythematosus ( SLE) or SLE-like disease; and (2) other connective tissue disease., Results: A total of 187 women (mean 33±5 years) with seronegative APS were included from 14 centres in Austria, Spain, Italy, Slovenia and France and compared with 285 patients with seropositive APS. Seronegative APS has more obstetrical rather than thrombotic phenotypes, with only 6% of venous thrombosis in comparison to seropositive APS. Cumulative incidence of adverse obstetrical events was similar in seronegative and seropositive APS patients, although higher rates of intrauterine deaths (15% vs 5%; p=0.03), of preeclampsia (7% vs 16%, p=0.048) and lower live birth term (36±3 vs 38±3 weeks of gestation; p=0.04) were noted in seropositive APS. The cumulative incidence of adverse obstetrical events was significantly improved in treated versus untreated seronegative APS (log rank<0.05), whereas there was no difference between patients who received aspirin or aspirin-low-molecular weighted heparin combination., Conclusion: Several non-criteria APL can be detected in patients with clinical APS features without any conventional APL, with various rates. The detection of non-criteria APL and thus the diagnosis of seronegative APS could discuss the therapeutic management similar to seropositive APS, but well-designed controlled studies are necessary., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: We examined the initial features, course, and prognosis of giant cell arteritis (GCA) in patients ≥ 85 years of age (≥85 year) and compared them to those of younger patients., Methods: The present retrospective study included all patients who were newly diagnosed with GCA in the Internal Departments of two French University Hospitals from 1976 or 1998 to 2017 and who were followed up for at least 6 months. Logistic regression analyses were conducted to identify baseline and prognostic characteristics associated with being ≥85 year., Results: Of the 865 patients assessed in this study, 87 were ≥85 year. Compared to younger patients, patients ≥ 85 year had more comorbid conditions (odds ratio [OR] = 1.11-1.74, p < 0.01), less often exhibited polymyalgia rheumatica (PMR; OR = 0.33-0.96, p = 0.04), and more often developed permanent visual loss (OR = 1.29-3.81, p < 0.01). The older patients also showed less dependence on glucocorticoid (GC) medications (OR = 0.23-0.94, p = 0.04), had fewer relapses (OR = 0.31-0.87, p = 0.015), less often recovered from GCA (OR = 0.22-0.69, p < 0.01), and more often died during treatment (OR = 1.45-4.65, p = 0.001) compared to younger patients. Being ≥85 year was the only factor associated with an increased 1-year mortality (hazard ratio = 1.77-5.81, p = 0.0001) for the whole cohort., Conclusions: GCA in very elderly patients was characterized by a higher rate of severe ischemic complications and an increased risk for early death compared to younger patients. Thus, there is a need for the early diagnosis of GCA and close clinical monitoring in this unique population., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Nonadherence to treatment is a major cause of lupus flares. Hydroxychloroquine (HCQ), a major medication in systemic lupus erythematosus, has a long half-life and can be quantified by high-performance liquid chromatography. This international study evaluated nonadherence in 305 lupus patients with flares using drug levels (HCQ < 200 ng/ml or undetectable desethylchloroquine), and self-administered questionnaires (MASRI < 80%). Drug levels defined 18.4% of the patients as severely nonadherent. In multivariate analyses, younger age, nonuse of steroids, higher body mass index, and unemployment were associated with nonadherence by drug level. Questionnaires classified 23.4% of patients as nonadherent. Correlations between adherence measured by questionnaires, drug level, and physician assessment were moderate. Both methods probably measured two different patterns of nonadherence: self-administered questionnaires mostly captured relatively infrequently missed tablets, while drug levels identified severe nonadherence (i.e., interruption or erratic tablet intake). The frequency with which physicians miss nonadherence, together with underreporting by patients, suggests that therapeutic drug monitoring is useful in this setting.

Objective: We investigated the development of giant cell arteritis (GCA) in patients with prior diagnoses of isolated polymyalgia rheumatica and/or peripheral arthritis (PMR/PA), and the potentially relevant characteristics of both illnesses in such patients., Methods: We retrospectively compared the features of 67 patients at the onset of PMR/PA, and their outcomes, to those of a random group of 65 patients with PMR/PA who did not develop late GCA. We also compared the features and outcomes of patients with late GCA to those of a random sample of patients with more usual GCA (65 with concurrent PMR/PA and 65 without)., Results: Patients with late GCA represented 7.4% of all patients with GCA included in a large hospital-based inception cohort. PMR/PA preceded overt GCA by 27 months on average. Permanent visual loss developed in 10 patients, including 8 of 48 (17%) patients featuring cranial arteritis. A questionable female predominance was the only distinguishing feature of PMR/PA evolving into GCA; late GCA more often featured subclinical aortitis (OR 6.42, 95% CI 2.39-17.23; p < 0.001), headache (OR 0.44, 95% CI 0.19-1.03; p = 0.06), and fever (OR 0.29, 95% CI 0.13-0.64; p = 0.002) less often compared to the more usual form of GCA. Patients with either form of GCA experienced similar outcomes., Conclusion: A cranial arteritis pattern of late GCA is associated with a significant risk for ischemic blindness. However, compared to the usual form of GCA, late GCA is often less typical, with a higher frequency of silent aortitis. Patients with relapsing/refractory PMR may not be at increased risk for late GCA.

Although a glucocorticoid (GC)-sparing strategy is needed for patients with giant cell arteritis (GCA) suffering from refractory disease or serious treatment-related complications, evidence of efficacy in this setting of immunosuppressive drugs and biotherapies is lacking. Herein, we evaluated the GC-sparing effects and tolerability of addition of dapsone (DDS) to prednisone therapy in patients with GCA. We retrospectively assessed data on 18 GCA patients who received DDS as a first-line treatment (DDS-1 group) and 52 patients who received it as a second- or third-line treatment for refractory GCA, with or without excessive GC-related toxicity (DDS-2 group). Of these 70 patients, 63 belonged to an inception cohort of 478 patients, whereas the remaining 7 were referred to our department for resistant GCA. In all, 52 patients were assessable for DDS efficacy. The baseline characteristics of the DDS-1 patients were similar to those of 395 GCA patients (control group) who received prednisone alone. DDS-1 patients had a more sustained decrease in GC dose with a lower mean prednisone dose at 12 months, and they comprised higher proportions who achieved GC withdrawal within the first year, who stopped prednisone treatment, and who recovered from GCA (P < 0.001 for each variable). Patients in the DDS-2 group achieved a mean rate of prednisone reduction of 65% and a prednisone dose reduction of 16.9 ± 13.3 mg/d. The monthly decreases in the prednisone dose were 2.4 and 1.25 mg in DDS-1 and DDS-2 patients, respectively. DDS-induced side effects were recorded in 44 (64%) assessable patients. These side effects led to lowering of the DDS dose by 25 mg/d in 11 (16%) patients and permanent cessation of DDS in 14 patients (20%), due to allergic skin rash in 7, agranulocytosis in 2, icteric hepatitis in 2, and excessive hemolysis in 2 patients. DDS is a potent GC-sparing agent in GCA that should be evaluated in prospective studies. However, DDS use should be restricted to refractory GCA patients due to its toxicity, and close clinical and laboratory monitoring for 3 months is necessary., Competing Interests: The authors have no funding and conflicts of interest to disclose.

Objectives: Idiopathic inflammatory myopathies (IIM) are heterogeneous autoimmune diseases with wide clinical spectrum that may lead to delayed diagnosis. The aim of this study was to examine the impact of IIM-specific dot-blot assay on diagnostic process of patients presenting with muscular or systemic symptoms evocating of IIM., Methods: We collected all the prescriptions of an IIM specific dot-blot assay (8 autoantigens including Jo-1, PL-7, PL-12, SRP, Mi-2, Ku, PM/Scl and Scl-70) over a 38-month period., Results: 316 myositis dot-blot assays (MSD) were performed in 274 patients (156 women, mean age 53±10.6 years) referring for muscular and/or systemic symptoms suggesting IIM. The timing of dot prescription through the diagnostic process was highly variable: without (35%), concomitantly (16%) or after electromyographic studies (35%). Fifty-nine patients (22%) had IIM according to Bohan and Peter's criteria. Among them, 29 (49%) had positive dot (8 Jo-1, 6 PM-Scl, 5 PL-12, 5 SRP, 2 Mi-2, 2 PL-7 and 1 Ku). Various other diagnoses were performed including 35 autoimmune disease or granulomatosis (12%), 19 inflammatory rheumatic disease (7%), 16 non inflammatory muscular disorders (6%), 10 drug-induced myalgia (4%), 11 infectious myositis (4%). Except 11 borderline SRP results and one transient PM-Scl, MSD was positive only in one case of IIM. Dot allowed clinicians to correct diagnosis in 4 cases and improved the diagnosis of IIM subtypes in 4 cases., Conclusions: This study reflects the interest of myositis dot in the rapid diagnosis process of patients with non-specific muscular symptoms leading to various diagnoses including IIM.

Objective: To determine the risk factors for permanent visual loss (PVL) in patients with biopsy-proven giant cell arteritis (GCA) and the usefulness of the factors in clinical practice., Methods: From 1976 through 2015, the clinical charts and laboratory results of 339 patients with biopsy-proven GCA were recorded prospectively at the time of diagnosis. We used multivariable logistic regression analysis to determine which of 24 pretreatment characteristics were associated with PVL., Results: Visual ischemic manifestations occurred in 108 patients, including PVL in 53 (16%), bilaterally in 15 patients (28%). The independent predictors associated with an increased risk of PVL were age (OR 1.06, 95% CI 1.01-1.12, p = 0.01), a history of transient visual ischemic symptoms (OR 2.62, 95% CI 1.29-5.29, p < 0.01), and jaw claudication (OR 2.11, 95% CI 1.09-4.10, p = 0.03). The presence of fever (OR 0.30, 95% CI 0.14-0.64, p < 0.01) and rheumatic symptoms (OR 0.23, 95% CI 0.10-0.57, p = 0.001) were associated with a markedly reduced risk of developing visual loss (3.7% if features were both present). No laboratory variables were independently associated with PVL., Conclusion: The visual ischemic risk of untreated GCA can be readily estimated upon simple clinical findings, but not laboratory variables. However, we did not identify a subgroup of patients carrying no risk of developing visual loss. Glucocorticoid treatment remains, therefore, urgent for any patient with a high clinical suspicion index.

Objective: To investigate association between genetic polymorphisms of GST, CYP and renal outcome or occurrence of adverse drug reactions (ADRs) in lupus nephritis (LN) treated with cyclophosphamide (CYC). CYC, as a pro-drug, requires bioactivation through multiple hepatic cytochrome P450s and glutathione S transferases (GST)., Methods: We carried out a multicentric retrospective study including 70 patients with proliferative LN treated with CYC. Patients were genotyped for polymorphisms of the CYP2B6, CYP2C19, GSTP1, GSTM1 and GSTT1 genes. Complete remission (CR) was defined as proteinuria ≤0.33g/day and serum creatinine ≤124 µmol/l. Partial remission (PR) was defined as proteinuria ≤1.5g/day with a 50% decrease of the baseline proteinuria value and serum creatinine no greater than 25% above baseline., Results: Most patients were women (84%) and 77% were Caucasian. The mean age at LN diagnosis was 41 ± 10 years. The frequency of patients carrying the GST null genotype GSTT1-, GSTM1-, and the Ile→105Val GSTP1 genotype were respectively 38%, 60% and 44%. In multivariate analysis, the Ile→105Val GSTP1 genotype was an independent factor of poor renal outcome (achievement of CR or PR) (OR = 5.01 95% CI [1.02-24.51]) and the sole factor that influenced occurrence of ADRs was the GSTM1 null genotype (OR = 3.34 95% CI [1.064-10.58]). No association between polymorphisms of cytochrome P450s gene and efficacy or ADRs was observed., Conclusion: This study suggests that GST polymorphisms highly impact renal outcome and occurrence of ADRs related to CYC in LN patients.

In European multicenter study, we aimed to describe the real-life hydroxychloroquine use in APS patients during pregnancy and determine its benefit in refractory obstetrical APS. We analyzed the outcome of pregnancies treated by hydroxychloroquine in patients with APS or asymptomatic antiphospholipid (aPL) antibodies carriers. Thirty patients with APS with 35 pregnancies treated by hydroxychloroquine were analyzed. Comparing the outcome of pregnancies treated by the addition of hydroxychloroquine to previous pregnancies under the conventional treatment, pregnancy losses decreased from 81% to 19% (p<0.05), without differences in the associated treatments. The univariate analysis showed that the previous intrauterine deaths and higher hydroxychloroquine amount (400mg per day) were the factors associated with pregnancy outcome. Considering 14 patients with previous refractory obstetrical APS (n=5 with obstetrical and thrombotic primary APS and n=9 with purely obstetrical APS), all with previous pregnancy losses under treatment (aspirin with LMWH in 11 cases and LMWH in 3 cases), the addition of hydroxychloroquine resulted in live born babies in 11/14 (78%) cases (p<0.05). Our study shows the benefit of hydroxychloroquine addition in patients with refractory obstetrical APS and raises the need of prospective studies to confirm our preliminary study., (Copyright © 2015 Elsevier B.V.

Background: Neurotrophins play a central role in the development and maintenance of the nervous system. However, neurotrophins can also modulate B and T cell proliferation and activation, especially via autocrine loops. We hypothesized that both serum and lymphocytic neurotrophin levels may be deregulated in systemic Lupus erythematosus (SLE) and may reflect clinical symptoms of the disease., Methods: Neurotrophins in the serum (ELISA tests) and lymphocytes (flow cytometry) were measured in 26 SLE patients and 26 control subjects. Th1 (interferon-γ) and Th2 (IL-10) profiles and serum concentration of BAFF were assessed by ELISA in the SLE and control subjects., Findings: We have demonstrated that both NGF and BDNF serum levels are higher in SLE patients than healthy controls (p=0.003 and p<0.001), independently of Th1 or Th2 profiles. Enhanced serum NT-3 levels (p=0.003) were only found in severe lupus flares (i.e. SLEDAI ≥ 10) and significantly correlated with complement activation (decreased CH 50, Γ=-0.28, p=0.03). Furthermore, there was a negative correlation between serum NGF levels and the number of circulating T regulatory cells (Γ=0.48, p=0.01). In circulating B cells, production of both NGF and BDNF was greater in SLE patients than in healthy controls. In particular, the number of NGF-secreting B cells correlated with decreased complement levels (p=0.05). One month after SLE flare treatment, BDNF levels decreased; in contrast, NGF and NT-3 levels remained unchanged., Conclusion: This study demonstrates that serum and B cell levels of both NGF and BDNF are increased in SLE, suggesting that the neurotrophin production pathway is deregulated in this disease. These results must be confirmed in a larger study with naive SLE patients, in order to avoid the potential confounding influence of prior immune-modulating treatments on neurotrophin levels.

Background: The aim of this paper was to study the evolution of primary Sjögren's syndrome (pSS) immunological profile, its impact on pSS activity and long-term evolution in a bicentric cohort of French patients with pSS (n = 445, mean age 53.6 ± 14 years, mean follow-up 76.1 ± 51 months)., Methods: This is a retrospective cohort study., Results: Two hundred twelve patients were Sjögren's syndrome A (SSA) positive, and 131 were both SSA and Sjögren's syndrome B (SSB) positive. Sixty-eight patients (15%) had cryoglobulinemia. Active systemic profile (i.e., hypergammaglobulinemia, rheumatoid factor (RF), and anti-Sjögren's syndrome A (anti-SSA), anti-Sjögren's syndrome B (anti-SSB) positivity), associated with multisystemic involvement, leads to an increased utilization of corticosteroid and hydroxychloroquine. Multivariate analysis pointed out independent statistical association between hypergammaglobulinemia, anti-SSA, anti-SSB, and RF. Cryoglobulinemia is associated with multi-systemic involvement, lymphoma, and pSS-related death., Conclusion: The subset of patients with active immunological profile is characterized by systemic complications leading to immunosuppressive drug utilization and polyclonal B-cell activation profile.

Background: Neurotrophins (NTs) are able to activate lymphocytes and fibroblasts; they can modulate angiogenesis and sympathic vascular function. Thus, they can be implicated in the three pathogenic processes of systemic sclerosis (SSc). The aims of this study are to determine blood levels of Nerve Growth Factor (NGF), Brain-Derived Neurotrophic Factor (BDNF) and Neurotrophin-3 (NT-3) in SSc and to correlate them with clinical and biological data., Methods: Serum samples were obtained from 55 SSc patients and 32 control subjects to measure NTs levels by ELISA and to determine their relationships with SSc profiles., Findings: Serum NGF levels were higher in SSc patients (288.26 ± 170.34 pg/mL) than in control subjects (170.34 ± 50.8 pg/mL, p<0.001) and correlated with gammaglobulins levels and the presence of both anti-cardiolipin and anti-Scl-70 antibodies (p<0.05). In contrast, BDNF levels were lower in SSc patients than in controls (1121.9 ± 158.1 vs 1372.9 ± 190.9 pg/mL, p<0.0001), especially in pulmonary arterial hypertension and diffuse SSc as compared to limited forms (all p<0.05). NT-3 levels were similar in SSc and in the control group (2657.2 ± 2296 vs 2959.3 ± 2555 pg/mL, NS). BDNF levels correlated negatively with increased NGF levels in the SSc group (and not in controls)., Conclusion: Low BDNF serum levels were not previously documented in SSc, particularly in the diffuse SSc subset and in patients with pulmonary hypertension or anti-Scl-70 antibodies. The negative correlation between NGF and BDNF levels observed in SSc and not in healthy controls could be implicated in sympathic vascular dysfunction in SSc.

Objective: To review personal and published observations of giant cell (temporal) arteritis (GCA) or polymyal-gia rheumatica (PMR) with familial or conjugal aggregation and emphasise on epidemiological, clinical and genetic features of such cases., Methods: We pooled data obtained from all cases of GCA or PMR with familial aggregation recruited in the department since 1976 and those from reports of familial or conjugal GCA or PMR published in the French-English literature since 1970., Results: During the study period, we diagnosed 460 patients (128 with isolated PMR, 227 with isolated GCA, 105 with PMR/CGA). No conjugal couples were observed in the whole series. No familial cases were identified among PMR patients, whereas the prevalence of familial GCA was 1 in 83 (1 in 250 to 500 expected by chance), as we identified 4 patients (brother-brother, sister with history of affected sister, and daughter with priory affected mother). An additional pair of sisters with TA, recruited several months after diagnosis, is also presented. Pooling data from 85 patients (74 with GCA) including our patients, representing 32 families and 8 conjugal pairs, enabled us to draw the following observations: 1) partial or full agreement in the clinical picture (GCA, PMR, or GCA/PMR) was observed in 96% of the siblings pairs, suggesting a common pathogenic mechanism; 2) five kindred were described in whom at least three members were affected; 3) the lag between manifested diseases in familial or conjugal pairs averaged 5.7 years, with synchronous or close disease occurrence in only 26% of the pairs; 4) 18 of 32 assessed patients (56%) carried the DR4 antigen., Conclusion: Our survey on familial aggregation of GCA and PMR accumulated data pointing to a genetic predisposition. However, environmental contagious factors could have trigger synchronous disease onset in up to one-fourth of the cases.
