Background: As lack of awareness of rare diseases (RDs) among healthcare professionals results in delayed diagnoses, there is a need for a more efficient approach to RD training during academic education. We designed an experimental workshop that used role-play simulation with patient educators and focused on teaching "red flags" that should raise the suspicion of an RD when faced with a patient with frequently encountered symptoms. Our objective was to report our experience, and to assess the improvement in learners' knowledge and the satisfaction levels of the participants.Results: The workshop consisted of 2 simulated consultations that both started with the same frequent symptom (Raynaud phenomenon, RP) but led to different diagnoses: a frequent condition (idiopathic RP) and an RD (systemic sclerosis, SSc). In the second simulated consultation, the role of the patient was played by a patient educator with SSc. By juxtaposing 2 seemingly similar situations, the training particularly highlighted the elements that help differentiate SSc from idiopathic RP. When answering a clinical case exam about RP and SSc, students that had participated in the workshop had a higher mean mark than those who had not (14 ± 3.7 vs 9.6 ± 5.5 points out of 20, p = 0.001). Participants mostly felt "very satisfied" with this training (94%), and "more comfortable" about managing idiopathic RP and SSc (100%). They considered the workshop "not very stressful" and "very formative" (both 71%). When asked about the strengths of this training, they mentioned the benefits of being put in an immersive situation, allowing a better acquisition of practical skills and a more interactive exchange with teachers, as well as the confrontation with a real patient, leading to a better retention of semiological findings and associating a relational component with this experience.Conclusions: Through the use of innovative educational methods, such as role-play simulation and patient educators, and by focusing on teaching "red flags", our workshop successfully improved RP and SSc learning in a way that satisfied students. By modifying the workshop's scenarios, its template can readily be applied to other clinical situations, making it an interesting tool to teach other RDs. [ABSTRACT FROM AUTHOR]

Background: Bradykinin-mediated angioedema (AE) is a complication associated with thrombolysis for acute ischemic stroke. Risk factors are unknown and management is discussed.Objectives: To clarify risk factors associated with bradykinin-mediated AE after thrombolysis for acute ischemic stroke.Methods: In a case-control study conducted at a French reference centre for bradykinin angiœdema, patients with thrombolysis for acute ischemic stroke and a diagnosis of bradykinin-mediated angiœdema, were compared to controls treated with thrombolysis treatment without angiœdema.Results: Fifty-three thrombolysis-related AE were matched to 106 control subjects. The sites of attacks following thrombolysis for ischemic stroke mainly included tongue (34/53, 64%) and lips (26/53, 49%). The upper airways were involved in 37 (70%) cases. Three patients required mechanical ventilation. Patients with bradykinin-mediated angiœdema were more frequently women [33 (62%) vs. 44 (42%); P = 0.01], had higher frequency of prior ischemic stroke [12 (23%) vs. 9 (8%); P = 0.01], hypertension [46 (87%) vs. 70 (66%); P = 0.005], were more frequently treated with angiotensin-converting enzyme inhibitor [37 (70%) vs. 28 (26%); P < 0.001] and were more frequently hospitalized in intensive care medicine [ICU; 11 (21%) vs. 5 (5%); P = 0.004]. In multivariate analysis, factors associated with thrombolysis-related AE were female sex [odds ratio (OR), 3.04; 95% confident interval (CI), 1.32-7.01; P = 0.009] and treatment with angiotensin-converting enzyme inhibitors [(OR), 6.08; 95% (CI), 2.17-17.07; P < 0.001].Conclusions: This case-control study points out angiotensin-converting enzyme inhibitors and female sex as risk factors of bradykinin AE associated with thrombolysis for ischemic stroke.

Purpose: The purpose of this study was to evaluate the safety of antithrombotic treatments prescribed during pregnancy in patients with antiphospholipid syndrome (APS). Methods: This international, multicenter study included two cohorts of patients: a retrospective French cohort and a prospective US cohort (PROMISSE study). Inclusion criteria were (1) APS (Sydney criteria), (2) live pregnancy at 12 weeks of gestation (WG) with (3) follow-up data until six weeks post-partum. According to APS standard of care, patients were treated with aspirin and/or low-molecular weight heparin (LMWH) at prophylactic (pure obstetric APS) or therapeutic doses (history of thrombosis). Major bleeding was defined as abnormal blood loss during the pregnancy and/or post-partum period requiring intervention for hemostasis or transfusion, or during the peripartum period greater than 500mL and/or requiring surgery or transfusion. Other bleeding events were classified as minor. Results: Two hundred and sixty-four pregnancies (87 prospectively collected) in 204 patients were included (46% with history of thrombosis, 23% with associated systemic lupus). During pregnancy, treatment included LMWH (n=253; 96%) or low-dose aspirin (n=223; 84%), and 215 (81%) patients received both therapies. The live birth rate was 89% and 82% in the retrospective and prospective cohorts, respectively. Adverse pregnancy outcomes occurred in 28% of the retrospective cohort and in 40% of the prospective cohort. No maternal death was observed in either cohort. A combined total of 45 hemorrhagic events (25%) occurred in the retrospective cohort, but major bleeding was reported in only six pregnancies (3%). Neither heparin nor aspirin alone nor combined therapy increased the risk of hemorrhage. We also did not observe an increased rate of bleeding in the case of a short interval between last LMWH (less than 24 hours) or aspirin (less than f ive days) doses and delivery. Only emergency Caesarean section was significantly associated with an increased risk of bleeding (odds ratio (OR) 5.03 (1.41-17.96); p=.016). In the prospective cohort, only one minor bleeding event was reported (vaginal bleeding). Conclusion: Our findings support the safety of antithrombotic therapy with aspirin and/or LMWH during pregnancy in high-risk women with APS, and highlight the need for better treatments to improve pregnancy outcomes in APS.

Background/Purpose Long-term anticoagulation is the standard treatment for thrombotic antiphospholipid syndrome (APS). However, in daily practice, the question of withdrawing anticoagulation may arise, without any evidence-based recommendations. This study aimed to assess outcomes in APS patients after anticoagulation withdrawal. Methods Thrombotic APS patients followed in our centre, whose anticoagulation was withdrawn after APS diagnosis, were retrospectively selected, and were match-controlled with patients under anticoagulation, based on sex, age, APS clinical phenotype and disease duration. Results Thirty cases with anticoagulation withdrawal were included. Median follow-up was 51 months (12–124). The risk of thrombotic relapse was higher in cases compared to controls (7.3% versus 1.5% patient-year (p = 0.01); hazard ratio 4.8; 95% confidence interval (1.4–16.7)). Male gender, anti-β2GP1 and triple positivity at inclusion were predictive factors for thrombotic relapse. Conversely, aspirin prescription was a protective factor against relapses. Persistence of LA, anti-β2GP1 and triple positivity over time were associated with a higher risk of thrombosis and aPL disappearance with a lower risk. Conclusion In our study, anticoagulation withdrawal was associated with an increased risk of thrombotic relapse. Our findings emphasize the influence of anti-β2GP1 and triple positivity persistence over time on the risk of relapse and the benefit of aspirin prescription when anticoagulation has been withdrawn.

Introduction The long-term risk of first thrombosis and benefit of prophylaxis in antiphospholipid antibody (aPL) carriers without history of thrombosis or obstetrical morbidity is poorly known. This study aimed to evaluate the long-term rate and risk factors associated with a first thrombosis in those patients. Patients and methods After a prior study ended in December 2005 and was already published, we extended the follow-up period of our cohort of aPL carriers. Results Ninety-eight of the 103 patients of the previous study were included. The annual first thrombosis rate was 2.3% per patient-year during a median of 13 years (6–17). None of the baseline characteristics was predictive of risk of first thrombosis, but persistent aPL over time were associated with an increased risk. The stronger association was found in triple aPL-positive carriers: OR 3.38 (95% CI: 1.24–9.22). Of note, conversely to our previous findings, no benefit of aspirin prophylaxis was observed. Conclusion The risk of first thrombosis in aPL carriers without history of thrombosis or obstetrical morbidity was significant, persisted linearly over time and was associated with persistent aPL. This risk was especially increased in triple aPL-positive carriers, in whom a close follow-up seems to be necessary. Nevertheless, the benefit of aspirin prophylaxis remained unclear.

Hereditary angioedema (HAE) is a rare disease associated with either a quantitative or qualitative deficiency in C1-inhibitor (C1-INH) or normal C1-INH. HAE with normal C1-INH is associated in 20% of cases with mutations in the gene for factor XII (FXII) or FXII-HAE. A recent review described 41 families, including 14 German and 15 Spanish families. We have constructed a register of French patients and their characteristics. A national survey was launched through the French National Center of Reference for Angioedema (CREAK) to study the clinical, biological and therapeutic characteristics of patients with HAE linked to a mutation of FXII gene. Fifty-seven patients were identified from 24 different families. In most cases they were young women (mean age at diagnosis: 31 years, mean age at first symptom: 21 years, female/male ratio: 76%). Twenty-one per cent of the patients experienced angioedema attacks only during pregnancy or when on oestrogen contraception. Sixty-three per cent had attacks at all times, but they were more severe during these same periods. Male carriers of the mutation were more frequently asymptomatic than females ( P = 0·003). C1-INH concentrate and icatibant were both effective for treating attacks. The prophylactic use of tranexamic acid led to a 64% decrease in the number of attacks. This is one of the largest series reported of HAE patients with FXII mutation. The therapeutic management appeared to be identical to that of HAE with C1-INH deficiency. [ABSTRACT FROM AUTHOR]

Background: Hereditary angioedema (HAE) with normal CI inhibitor (Cllnh) associated with the c.983C>A and c.983C>G mutations of the F12 gene (FXIIHAE) is a rare condition, and presents with highly variable clinical expression. On the basis of data gathered from a large carrier cohort, we assessed the modifiers affecting the clinical phenotype. Methods: We analyzed clinical and biological data recorded from 118 mutation carriers (80 symptomatic and 38 asymptomatic), 58 noncarrier relatives from 40 families, and 200 healthy donors. Disease severity was scored in relation to frequency and location of edema, as well as age at disease onset. To predict FXII-HAE disease severity, we analyzed the biological phenotype [Cllnh, C4, spontaneous amidase, angiotensin-I-converting enzyme (ACE), aminopeptidase P (APP), and carboxypeptidase N/M (CPN)] by means of logistic regression (Akaike information criterion) and odds ratio (OR). Results: Meaningful variables contributed to FXII-HAE, with the kinin catabolism enzymes ACE and CPN exhibiting a significant inverse relationship with disease severity (OR = 0.36, 95% CI 0.23-0.59, P < 0.001; OR = 0.58, 95% CI 0.36-0.91, P < 0.05, respectively). CPN activities were 37.5 (28.5-41.3) nmol/ml/ min and 38.5 (32.8-15.6) for FXII-HAE asymptomatic and symptomatic carriers, respectively, and 37.9 (30.5-43.7) nmol/ml/min for noncarriers. Angiotensin-Iconverting enzyme activities were 58 (44-76) and 49 (35-59) nmol/ml/min for FXII-HAE asymptomatic and symptomatic carriers, respectively, and 56 (49-66) nmol/ml/min for noncarriers. Conclusions: The FXII-HAE is associated with modifiers, for example kinin catabolism enzymes, ACE and CPN, different from those recognized in HAE with Cllnh deficiency. [ABSTRACT FROM AUTHOR]

Levamisole (an increasingly frequent contaminant of cocaine) can cause antineutrophil cytoplasmic antibody-associated vasculitis. Dermatologists should consider a diagnosis of cocaine/levamisole-associated cutaneous vasculopathy syndrome in cases of purpura of the ears and/or extensive retiform purpura in drug users. We report a case of particularly severe levamisole-induced necrotic purpura and immunological abnormalities in a 40-year-old woman. [ABSTRACT FROM AUTHOR]

Angioedema ( AE) is a clinical syndrome characterized by localised swelling lasting several hours. The swelling is often recurring and can be lethal if it is located in the laryngeal region. Much progress has been made recently in the treatment of acute episodes, but no consensus has been reached on maintenance treatment. We have performed a national retrospective observational study to assess the use of tranexamic acid ( TA) as maintenance treatment for non-histaminergic AE [hereditary AE ( HAE) or idiopathic non-histaminergic AE]. Records for 64 cases were collected from 1 October 2012 to 31 August 2013; 37 of these were included (12 HAE with C1-inhibitor deficiency, six with HAE with normal C1-inhibitor and 19 idiopathic non-histaminergic AE). When treated with TA over six months, the number of attacks was reduced by 75% in 17 patients, 10 patients showed a lower level of reduction and 10 had the same number of attacks. In no instances were symptoms increased. No thromboembolic events were observed, and the main side effects were digestive in nature. Thus, TA, which is well tolerated and inexpensive, appears to be an effective maintenance treatment for some patients with HAE or idiopathic non-histaminergic AE. [ABSTRACT FROM AUTHOR]

Background Hereditary angioedema attacks can be induced or worsened by oral contraceptive containing oestrogens. Objectives The purpose of this study was to assess the impact of progestin contraceptives on angioedema attacks. Methods We conducted a French retrospective, multi-centre study of progestin contraception in women with non-allergic angioedema, including hereditary angioedema type I, II and III and idiopathic angioedema. Patients were classified into four groups according to frequency of attacks. We evaluated the effects of progestin on the mean number of attacks and compared the number of patients in each group before and under progestin contraception. The influence of hormonal factors on the course of angioedema was also assessed. Results Fifty-five women were included: mean age was 32.1 years (16-52) and mean follow-up 32.4 months ( SD:29). Fourteen women were classified as type I (25.4%), two as type II (3.6%) and 19 as type III (34%) and 20 were idiopathic (36%). Seventeen patients were taking a low dose progestin-only pill ( POP), 24 antigonadotropic progestins ( AGP) and 14 both successively. Total or partial improvement was observed in 81.8% (45/55) of the patients and more frequently in those on an AGP agent (34 patients, 89.5%) than on POP (19 patients, 61.3%) ( P = 0.013). Conclusions & Clinical Relevance This is the first study evaluating the interest of antigonadotropic progestin contraception in a series of women with non-allergic angioedema. Progestins, especially antigonadotropic progestins, appear to convey a marked benefit in most cases. Antigonadotropic progestins could thus be recommended as adjuvant treatment in childbearing women with non-allergic angioedema. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the expression and activation of mitogen-activated protein kinases in patients with early arthritis who are disease-modifying antirheumatic drug (DMARD) naïve.Methods: A total of 50 patients with early arthritis who were DMARD naïve (disease duration <1 year) were prospectively followed and diagnosed at baseline and after 2 years for undifferentiated arthritis (UA), rheumatoid arthritis (RA) (1987 American College of Rheumatology (ACR) and 2010 ACR/European League Against Rheumatism (EULAR) criteria), or spondyloarthritis (SpA). Synovial biopsies obtained at baseline were examined for expression and phosphorylation of p38, extracellular signal regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) by immunohistochemistry and digital analysis. Synovial tissue mRNA expression was measured by quantitative PCR (qPCR).Results: ERK and JNK activation was enhanced at inclusion in patients meeting RA criteria compared to other diagnoses. JNK activation was enhanced in patients diagnosed as having UA at baseline who eventually fulfilled 1987 ACR RA criteria compared to those who remained UA, and in patients with RA fulfilling 2010 ACR/EULAR criteria at baseline. ERK and JNK activation was enhanced in patients with RA developing progressive joint destruction. JNK activation in UA predicted 1987 ACR RA classification criteria fulfilment (R(2)=0.59, p=0.02) after follow-up, and disease progression in early arthritis (R(2)=0.16, p<0.05). Enhanced JNK activation in patients with persistent disease was associated with altered synovial expression of extracellular matrix components and CD44.Conclusions: JNK activation is elevated in RA before 1987 ACR RA classification criteria are met and predicts development of erosive disease in early arthritis, suggesting JNK may represent an attractive target in treating RA early in the disease process.

Objective To evaluate rituximab (RTX) in primary Sjögren's syndrome (pSS) with peripheral nervous system (PNS) involvement. Methods Patients with pSS and PNS involvement who were included in the French AIR registry were analysed. Results 17 patients (age 60 years (44-78 years); 14 were female) were analysed. Neurological improvement was noted in 11 patients (65%) at 3 months. Rankin scale decreased from 3 (1-5) to 2 (1-5), 2 (1-5) and 2 (1-6) after 3, 6 and 9 months (p=0.02). European Sjögren's Syndrome Disease Activity Index decreased from 18 (10-44) to 11 (5-20), 11 (5-29) and 12 (5-30) after 3, 6 and 9 months (p<0.05). RTX was effective in neurological involvement in 9/10 patients with vasculitis or cryoglobulinaemia (90%) (group 1) at 3 months and in 2/7 cases (29%) without cryoglobulinaemia and vasculitis (p=0.03). Rankin and European Sjögren's Syndrome Disease Activity Index scales decreased significantly in group 1. Conclusion RTX seems effective in cryoglobulinaemia or vasculitis-related PNS involvement in pSS. [ABSTRACT FROM AUTHOR]

Background: Pulmonary hypertension (PH) complicating systemic sclerosis (SSc)-related interstitial lung disease (ILD) is usually associated with a poor prognosis. However, data are either lacking or scarce on prognostic factors in this condition. The objectives of this study were to compare the survival of patients with ILD-associated PH (PH-ILD) or pulmonary arterial hypertension (PAH) and to determine whether the severity of PH has prognostic value in SSc-associated PH-ILD.Methods: Consecutive patients with SSc and PH-ILD (n = 47) or PAH (n = 50) confirmed by right-sided heart catheterization were included in a cross-sectional analysis. PH was classified as mild (mean pulmonary arterial pressure [mPAP] ≤ 35 mm Hg) or moderate to severe (mPAP > 35 mm Hg).Results: As compared with patients with PAH, subjects with PH-ILD were younger, were more frequently men with a history of smoking, had more frequently diffuse SSc, less frequently anticentromere antibodies, and a lower FVC/diffusing capacity of lung for carbon monoxide (DLCO) ratio. They had a worse prognosis than patients with PAH (3-year survival of 47% vs 71%, respectively; P = .07). Patients with mild PH-ILD had similar poor outcomes when compared with those with moderate to severe PH-ILD. Pericardial effusion (hazard ratio [HR], 2.44; P = .04) and lower DLCO (HR, 0.96; P = .01) were the only independent factors predictive of a poor survival in the PH-ILD group.Conclusions: Patients with SSc with PH-ILD had a different phenotype and a worse prognosis than those with SSc and PAH. Lower DLCO and presence of pericardial effusion were predictive of a poor outcome in PH-ILD, whereas mPAP seemed to have no prognostic significance. [ABSTRACT FROM AUTHOR]

Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by arterial and/or venous thromboses and/or pregnancy-associated morbidity. Some patients develop only obstetric complications (obstetric APS), but data on the frequency of thrombotic events during the follow-up of these patients are scarce. This study was undertaken to evaluate the rate of thrombotic events after obstetric APS diagnosis according to the 2006 revised criteria. In total, 32 obstetric APS patients were retrospectively studied, with mean follow-up of 50 ± 37 months. After delivery, aspirin was prescribed to all patients as primary thrombosis prevention. The thrombosis rate was 3.3/100 patient-years and was 4.6, 4.5 and 10/100 patient-years when we considered at least two antiphospholipid antibody positivities (among lupus anticoagulant, anticardiolipin and anti-β2-glycoprotein-I), antinuclear antibody positivity or systemic lupus erythematosus-associated APS patients, respectively. The thrombosis rate was high after obstetric APS diagnosis, even for patients taking aspirin. Larger, prospective studies are needed to confirm this high frequency and determine the associated risk factors. [ABSTRACT FROM AUTHOR]

Objective: Little is known about systemic sclerosis (SSc)-related myopathy. We aimed to compare the clinical and immunological features of SSc patients with or without associated myopathy. Methods: Forty SSc patients with myopathy, defined by myalgia or muscle weakness associated with creatine kinase (CK) more than five times the upper limit range or myopathic electromyography (EMG) or abnormal myopathology, were identified from the records of four French hospital centres. For each patient, we selected two SSc controls matched for cutaneous SSc form, sex, age at SSc onset, and disease duration. We performed a case-control study testing clinical and immunological SSc-related features for association with myopathy by conditional logistic regression. Results: Muscle and SSc features of patients with myopathy did not differ significantly among the four centres of origin. Only four (10%) patients with SSc-associated myopathy had anti-polymyositis-scleroderma (PM-Scl) antibodies. Case-control univariate analysis revealed that reduced forced vital capacity (FVC) [odds ratio (OR) 3.0, 95% confidence interval (CI) 1.3-34.9], heart involvement, defined as clinical congestive heart failure, left ventricular ejection fraction (LVEF) < 60%, arrhythmia or conductive abnormalities (OR 2.9, 95% CI 1.3-6.5), and scleroderma renal crisis (OR 3.0, 95% CI 1.3-34.9) were significantly more frequent in patients with myopathy than in controls. Two autoantibodies were more frequent in patients with myopathy: anti-PM-Scl (OR 5.0, 95% CI 1.1-23.9) and anti-RNP (OR 6.9, 95% CI 1.1-64.4). Multivariate analysis retained two variables associated positively with myopathy [reduced FVC (OR 3.1, 95% CI 1.3-9.8) and heart involvement (OR 2.5, 95% CI 1.1-7.1)], while anti-centromere antibodies were associated negatively (OR 0.11, 95% CI 0.03-0.53). Conclusion: Heart monitoring of SSc patients with myopathy should be undertaken regularly because of the association of myocardial and skeletal myopathies in such patients. [ABSTRACT FROM AUTHOR]

Objectives: To assess the prevalence and patterns of cardiac abnormalities as detected by cardiac magnetic resonance imaging (MRI) in systemic sclerosis (SSc). Methods: Fifty-two consecutive patients with SSc underwent cardiac MRI to determine morphological, functional, perfusion at rest and delayed enhancement abnormalities. Results: At least one abnormality on cardiac MRI was observed in 39/52 patients (75%). Increased myocardial signal intensity in T2 was observed in 6 patients (12%), thinning of left ventricle (LV) myocardium in 15 patients (29%) and pericardial effusion in 10 patients (19%). LV and right ventricle (RV) ejection fractions were altered in 12 patients (23%) and 11 patients (21%), respectively. LV diastolic dysfunction was found in 15/43 patients (35%). LV kinetic abnormalities were found in 16/52 patients (31%) and myocardial delayed contrast enhancement was detected in 11/52 patients (21%). No perfusion defects at rest were found. Patients with limited SSc had similar MRI abnormalities to patients with diffuse SSc. Seven of 40 patients (17%) without pulmonary arterial hypertension had RV dilatation. Conclusions: This study shows that MRI is a reliable and sensitive technique for diagnosing heart involvement in SSc and for analysing its mechanisms, including its inflammatory, microvascular and fibrotic components. Compared with echocardiography, MRI appears to provide additional information by visualising myocardial fibrosis and inflammation. RV dilatation appeared to be non-specific for pulmonary arterial hypertension but could also reflect myocardial involvement related to SSc. Further studies are needed to determine whether cardiac MRI abnormalities have an impact on the prognosis and treatment strategy. [ABSTRACT FROM PUBLISHER]

Objectives: To describe the clinical characteristics and muscle pathological features of patients with systemic sclerosis (SSc) and myopathy and analyse their impact on muscle outcome. Methods: Thirty-five patients with myopathy and available muscle biopsy were restrospectively investigated from the charts of four hospital centres. Results: Twenty-six (74%) cases had diffuse SSc. The median time from SSc diagnosis was 5 years (range 0–23) at myopathy onset. The main myopathological features were mononuclear inflammation (63%), muscle atrophy (60%), necrosis (59%), regeneration (44%), fibrosis (24%) or microangiopathy (27%). After a median follow-up of 4.4 years, 24 patients (69%) showed complete or partial muscle remission. Only histological muscle inflammation was associated with good muscle prognosis in multivariate analysis (odds ratio 44.7, 95% CI 2.8 to 704.7). Patients without muscle inflammation had a poor response to corticosteroids (38% favourable response vs 90% in patients with inflammation). Conclusion: Muscle histopathology is critical in the therapeutic management of SSc-associated myopathy. [ABSTRACT FROM PUBLISHER]

Objective: To determine whether there were any clinical and biological differences between male and female patients with primary Sjogren's syndrome (pSS) in a large bicentric series of patient. Methods: We studied 419 consecutive patients (mean age at onset 53.6 years, mean disease outcome 73 months) with pSS according to American-European criteria, attending two different Departments of Internal Medicine in France. The 42 (9%) male patients in this cohort comprised the male group described in this study. Results: Extraglandular manifestations during the course of the disease were present in 37 (89%) of our male patients with pSS. The extraglandular manifestations were similar among the two groups except that the male patients showed a lower frequency of depression or asthaenia (5% vs. 20%, p = 0.014) compared with the females. A significantly greater percentage of women reported lymphopaenia (26% vs. 8%, p = 0.02) and leucopaenia (18% vs. 3%, p = 0.015) at onset, but thrombopaenia was more common in the male patients (21% vs. 6%, p = 0.001). Lymphoma development was slightly more common in the male patients, but with no statistical significance (10% vs. 3%, p = 0.06), and occurred earlier after the SS diagnosis (log rank test p = 0.04). Conclusion: Although pSS is typically a disease affecting women, clinicians should be aware that it may be diagnosed in male patients. Except for haematological presentation, we could not find any notable differences in clinical and immunological characteristics between male and female patients with pSS. [ABSTRACT FROM AUTHOR]

Idiopathic hypertrophic cranial pachymeningitis (IHCP) is a rare clinical entity, characterized by a chronic inflammation causing thickening of the dura. Adequate therapeutic management is still a matter of debate. We present a patient with an IHCP, non-responsive to corticotherapy. Oral methotrexate was introduced (12.5 mg weekly) and total remission was observed after 6 weeks, both clinically and after neuro-imaging. We conclude that methotrexate can be effective and a therapeutical option in patients with IHCP who are resistant to corticotherapy or present major side-effects of chronic corticosteroids use.

OBJECTIVE: To describe the response to first-line immunosuppressive therapy with or without pulmonary vasodilators in pulmonary arterial hypertension (PAH) associated with systemic lupus erythematosus (SLE) or mixed connective tissue disease (MCTD). METHODS: Twenty-three consecutive patients with SLE- or MCTD-associated PAH treated with first-line immunosuppressive therapy either alone (n = 16) or in combination with pulmonary vasodilators (n = 7) were evaluated according to clinical and hemodynamic criteria before and after immunosuppressive therapy. Responders were defined as patients in New York Heart Association (NYHA) functional class I or II with hemodynamic improvement after the last pulse of cyclophosphamide. RESULTS: Among the 16 patients treated with first-line immunosuppressive therapy alone, 8 (50%) were responders. These patients had a significantly improved NYHA functional class, 6-minute walking distance, and mean pulmonary artery pressure. Patients in NYHA functional class I or II and/or a cardiac index >3.1 liters/minute/m(2) at baseline were more likely to benefit from immunosuppressive therapy. Six of the 8 nonresponders subsequently improved with pulmonary vasodilators. Among the 7 patients who were initially treated with immunosuppressive therapy and pulmonary vasodilators, 4 (57.1%) were responders. CONCLUSION: PAH associated with SLE or MCTD may respond to a treatment combining cyclophosphamide and glucocorticoids. Patients who could benefit from this immunosuppressive therapy could be those who have less severe disease at baseline. For patients with more severe disease, pulmonary vasodilators should be started, possibly in combination with immunosuppressants. In any case, clinical and hemodynamic evaluations are mandatory to monitor the response and adapt the treatment. These retrospective and uncontrolled data need to be confirmed by randomized controlled trials. [ABSTRACT FROM AUTHOR]

One hundred and three consecutive asymptomatic anti-phospholipid (aPL) antibody-positive carriers, taking aspirin (n = 75) or not (n = 28), were studied retrospectively to determine whether aspirin could provide primary prevention of anti-phospholipid syndrome (APS) symptoms. All patients positive for anti-cardiolipin antibodies (aCL; >25 UGPL or UMPL) and/or lupus anti-coagulant were followed for a mean of 64 ± 24.7 months. Among aPL-positive patients, 37 had systemic lupus erythematosus (SLE), 20 had prolonged activated partial thromboplastin times, 19 had other connective tissue diseases, 16 had autoimmune thrombocytopenia (AIT), 11 had diverse diseases. Nineteen patients experienced thrombotic event(s) during follow-up. Clinical features, biological parameters and hydroxychloroquine use were comparable for the two groups, but thrombotic events differed (log-rank test; P = 0.02). Four of the 10 SLE patients not taking aspirin developed thrombosis compared with 3/27 SLE patients taking aspirin (log-rank test; P = 0.03). Anti-phospholipid -positive patients with AIT developed fewer thromboses while taking aspirin (log-rank test; P = 0.01). In conclusion, aPL-positive SLE and AIT patients should take aspirin to prevent APS manifestations. Prospective therapeutic trials are needed to confirm aspirin's prophylactic role in such patients.

The article examines whether forkhead box class O (FoxO) transcription factors are differentially inactivated in rheumatoid arthritis (RA) synovial tissue and whether this inactivation correlates with laboratory and clinical parameters of disease activity. The study found that all 3 FoxO family members examined were phosphorylated in both RA and osteoarthritis (OA) synovial tissue, specifically, the inactivation of FoxO4 was enhanced in macrophages from RA synovial tissue.

Muckle-Wells syndrome (MWS) is a dominantly inherited autoinflammatory disease characterized by rashes, fever, arthralgia, sensorineural deafness, and the possible development of systemic AA amyloidosis. We used anakinra to treat a 22-year-old patient with MWS who had deafness and a high serum level of C-reactive protein (CRP). Following treatment with anakinra, the patient's CRP level normalized, and she recovered from deafness. The fact that this occurrence has never been previously reported strengthens the role of anakinra in MWS but also raises new questions about the physiopathology of such deafness.

The aim of this study is to determine prevalence, clinical significance of antiphospholipid antibodies (aPL) including anticardiolipin antibodies (aCL), anti-β2GP1 and lupus anticoagulant (LA) in a cohort of 74 patients with primary Sjögren's syndrome (pSS) according to revised European criteria. aPL were found in 25 (34%) patients; IgG in 23 (12 had low titres, six moderate titres and five high titres) and IgM in five (three and two had respectively moderate and high titres). Eight (11%) patients were found to have LA; anti-β2GP1 antibodies were detected only in three (4%) patients. Only two patients with LA, aPL and β2GP1 had recurrent venous thrombosis. One patient with moderate titres of aPL exhibited recurrent spontaneous foetal losses. Peripheral neuropathies without cryoglobulinemiawere more frequent in the aPL group. Other systemic involvements of pSS were the same in both groups with or without aPL. Patients with aPL have more concurrentimmunological diseases such as thyroiditis and primary biliary cirrhosis and a higher prevalence of hypergammaglobulinemia (P < 0.05). Even if aPL prevalence reached 30% in pSS, titres were usually low, with a close correlation with hypergammaglobuliremia but not with antiphospholipid syndrome, which is related to positivity of both LA and aPL.

Background and objectives The angiogenic factors angiopoietin-1 (Ang-1) and Ang-2 are differentially expressed in the serum and synovial fluid of patients with different forms of arthritis. Ang-1 and Ang-2 contribute to inflammation and joint destruction in rheumatoid arthritis (RA), but the underlying mechanisms for their differential expression and their consequences for synovial Tie2 activation are unknown. Here the authors examined relationships between synovial expression of Ang-1 and Ang-2, and Tie2 activation in patients with RA and psoriatic arthritis (PsA), and the expression of transcription factors (TF) regulating Ang expression. Materials and methods Ang-1, Ang-2, Tie2 and phosphorylated (p) active Tie2 expression was examined by immunohistochemistry combined with digital image analysis in synovial biopsies from 20 RA and 19 PsA patients. Relationships between Ang expression and Tie2 activation were compared. analysis was conducted to identify possible TF candidates in the Ang-1 promoter, using four different TF binding site prediction programmes. RA synovial expression of TF and Ang-1 was examined in publicly available gene expression data sets. Candidate TF were characterised by immunohistochemistry. Results Synovial Ang-1 expression was elevated approximately fourfold in patients with RA (p<0.05), while Ang-2 expression was similar in RA and PsA. The ratio of Ang-1 expression to Ang-2 was increased in RA (integrated optical density±SEM, 4.87±1.02) versus PsA (0.57±0.20) (p<0.001), and Ang-1 expression inversely correlated with Ang-2 expression in RA synovial tissue (r=−0.784, p<0.005). Tie2 activation was enhanced in RA (0.62±0.10) compared to PsA (0.18±0.11) (p<0.05), and a strong positive correlation was observed between Tie2 engagement and the ratio of Ang-1/Ang-2 expression (r=0.786, p<0.01). Expression of three potential Ang-1 TF, USF-1, NF-YA and Elf-1 correlated strongly with Ang-1 expression in RA synovial tissue (p<0.05) and were readily detected by immunohistochemistry. Conclusions In RA, synovial Tie2 engagement is driven primarily by enhanced local Ang-1 production. Expression of Ang-1 is differentially regulated in RA and PsA, correlating with enhanced expression of putative Ang-1 TF in RA. [ABSTRACT FROM PUBLISHER]
