Pulmonary hypertension in connective tissue diseases: What every CTD specialist should know - but is afraid to ask!

Pulmonary hypertension (PH) is a possible complication of connective tissue diseases (CTDs), especially systemic sclerosis (SSc), systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD). It is defined by an elevation of the mean pulmonary arterial pressure above 20mmHg documented during a right heart catheterization (RHC). Due to their multiorgan involvement, CTDs can induce PH by several mechanisms, that are sometimes intricated: pulmonary vasculopathy (group 1) affecting arterioles (pulmonary arterial hypertension, PAH) and possibly venules (pulmonary veno-occlusive-like disease), left-heart disease (group 2), chronic lung disease (group 3) and/or chronic thromboembolic PH (group 4). PH suspicion is often raised by clinical manifestations (dyspnea, fatigue), echocardiographic data (increased peak tricuspid regurgitation velocity), isolated decrease in DLCO in pulmonary function tests, and/or unexplained elevation of BNP/NT-proBNP. Its formal diagnosis always requires a hemodynamic confirmation by RHC. Strategies for PH screening and RHC referral have been extensively investigated for SSc-PAH but data are lacking in other CTDs. Therapeutic management of PH depends of the underlying mechanism(s): PAH-approved therapies in group 1 PH (with possible use of immunosuppressants, especially in case of SLE or MCTD); management of an underlying left-heart disease in group 2 PH; management of an underlying chronic lung disease in group 3 PH; anticoagulation, pulmonary endartectomy, PAH-approved therapies and/or balloon pulmonary angioplasty in group 4 PH. Regular follow-up is mandatory in all CTD-PH patients.

Steroid hormones in systemic sclerosis: associations with disease characteristics and modifications during scleroderma renal crisis.

OBJECTIVE: The renin-angiotensin-aldosterone system (RAAS) and glucocorticoids (GCs) are involved in vascular remodeling and fibrosis, but have not been extensively studied in systemic sclerosis (SSc). Our aim was to investigate the RAAS and GC hormones in SSc patients. METHODS: Serum levels of renin (dosage and activity), aldosterone and its precursors (DOC, B, 18-OH-DOC, 18-OH-B), and GCs (cortisol, cortisone, 11-deoxycortisol, 18-OH-F) were assessed in 122 SSc patients and 52 healthy controls. After applying stringent inclusion criteria aimed at ensuring accurate hormone assessments (exclusion of interfering drugs, strict sampling conditions), we analyzed RAAS hormones in 61 patients, and GCs in 96 patients. Hormone levels were compared between patients and controls; and associations with disease characteristics were assessed in patients. RESULTS: Regarding RAAS hormones, SSc patients displayed significantly lower aldosterone levels (although within normal range), similar renin levels, and higher B levels than controls. Abnormal RAAS hormone levels were associated with a more severe SSc phenotype (lung and skin fibrosis, heart and pulmonary vascular involvements, inflammation). Regarding GC hormones, SSc patients had higher levels of cortisol, 11-desoxycortisol (precursor) and 18-OH-F (metabolite) but lower levels of cortisone (inactive counterpart) than controls.RAAS hormone levels were assessed in 5 SSc patients before and during scleroderma renal crisis (SRC): concentrations varied considerably between patients, but consistently included normal/increased aldosterone levels and elevated renin levels. CONCLUSION: RAAS and GC hormones are abnormally produced in SSc patients, especially in patients with severe SSc and during SRC. This could suggest a participation of these hormonal systems in SSc pathogenesis.

Atteintes coronariennes et artérite a cellules géantes : à propos de 2 cas et revue de la littérature.

INTRODUCTION: Coronaritis is a rare but serious complication of giant-cell arteritis (GCA), with an estimated prevalence of less than 1%, however difficult to establish, and of early onset. METHODS: We describe 2 cases of GCA presenting with coronaritis and present a review of the literature on this complication. RESULTS: The first patient presented with stable angina on common trunk coronaritis with ostial stenosis. Corticosteroid combined with tocilizumab from the outset resulted in improvement. Angioplasty was performed at 6months with good outcome. The second patient presented with asymptomatic tritruncular ostial coronaritis. Corticosteroid allowed clinic-biological improvement of GCA. Two years later, he presented relapse with an acute coronary syndrome, with favorable evolution after angioplasty, increase of corticosteroids and addition of tocilizumab. CONCLUSION: Patients presented were successfully treated with corticosteroids combined with tocilizumab and angioplasty of their coronary stenoses. Efficacy of tocilizumab in GCA has not been evaluated especially on coronaritis due to the rarity of this complication. Our experience and the cases reported in the literature suggest good results of angioplasty in this indication. Studies with long-term follow-up will be necessary to evaluate the risk of restenosis.

[Systemic sclerosis-related interstitial lung disease: Diagnostic and therapeutic strategy in the light of recent clinical trials]. / Pneumopathie interstitielle diffuse associée à la sclérodermie systémique : prise en charge diagnostique et thérapeutique à la lumière des essais thérapeutiques récents.

Systemic sclerosis (SSc) is an autoimmune disease associated to fibrotic manifestations. Interstitial lung disease (SSc-ILD), one of the main fibrotic features of SSc, is the first cause of SSc-related death. The management of SSc-ILD has recently benefited from the results of key randomised controlled trials. French authorities have approved Nintedanib for the treatment of SSc-ILD, and tocilizumab has recently been approved by the Food and Drug Administration (FDA) in the United-States (US). These recent approvals challenge the management of this fibrotic manifestation of SSc. This narrative literature review, at the crossroad of internal medicine and pulmonology, discusses what could be an up-to date approach, in terms of diagnostic and therapeutic strategies for SSc-ILD, in the light of the results from recent clinical trials.

[Telomeropathies: A study of 15 cases]. / Téloméropathies de recrutement hématologique : étude de 15 cas.

INTRODUCTION: Telomeres are composed of a repeated sequence of double-stranded nucleotides TTAGGG and numerous proteins including the Shelterin complex. Their main role is to maintain the stability of the genome during cell replication through a mechanism of copying the repeted sequence by the telomerase complexe. All the diseases involving a deregulation of this complex are now grouped together under the term telomeropathies. They are difficult to diagnose and manage. Our objective was to describe the clinico-biological characteristics and treatments used, in patients affected by telomeropathies previously seen by an hematologist followed at the Lille University Hospital Center. METHODS: This is a retrospective, single-center study carried out within the department of internal medicine-clinical immunology, Reference center for rare autoimmune and systemic diseases at Lille University Hospital Center between 2005 and 2020 including all patients followed for telomeropathy. RESULTS: Probands and relatives were included. Fifteen patients were studied from 10 independant families. Sixty percent had an heterozygous TERC gene mutation. Sixty seven percent had haematological diseases including macrocytosis, anemia and/or thrombocytopenia, 20 % had a fibrotic hepatic disease, 27 % had a fibrotic pulmonary disease. Lymphocyte immunophenotyping showed a double negative T lymphocyte population with γδ TCR expression in 5 (33 %) patients. Forty-seven percent of the patients had not received any treatment. Twenty-seven percent were on androgen therapy. Twenty percent had received cyclosporine and 13 % anti-lymphocyte serum in the context of initial misdiagnosis. CONCLUSION: It is important to be aware of the complexity of telomeropathies, a differential diagnosis of immune aplastic anemia, in order to optimize management and avoid inappropriate treatments. Allografting of hematopoietic stem cells is the only potentially curative treatment. Our analysis found particularities in immunophenotyping lymphocyte not previously described to our knowledge, whose physiopathological imputability remains to be demonstrated.

Electro-clinical presentation of hereditary transthyretin related amyloidosis when presenting as a polyneuropathy of unknown origin in northern France.

INTRODUCTION: Hereditary transthyretin related amyloidosis (h-ATTR) classically presents as a small fiber neuropathy with positive family history, but can also be revealed by various other types of peripheral neuropathy. OBJECTIVE: To describe the initial electro-clinical presentation of patients from in a single region (northern France) of h-ATTR when it presents as a polyneuropathy of unknown origin. METHOD: We reviewed the records of patients referred to two neuromuscular centers from northern France with a peripheral neuropathy of unknown origin who were subsequently diagnosed with h-ATTR. RESULTS: Among 26 h-ATTR patients (10 Val30Met, 16 Ser77Tyr), only 14 patients had a suspicious family history (53.8%). The electro-clinical presentation was mostly a large-fiber sensory motor polyneuropathy (92.3%), which could be symmetric or not, length-dependent or not, or associated with nerve entrapment or not. Demyelinating signs were observed in 17 patients (70.8%), among whom nine fulfilled the criteria for a definite diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy (37.5%). CONCLUSION: h-ATTR may have a wide spectrum of clinical profiles, and should be considered in the screening of polyneuropathies of unknown origin.

[Impact of disease on daily activities, emotions and quality of life of patients with hereditary angioedema]. / Impact de l'angiœdème héréditaire sur les activités de la vie quotidienne, la sphère émotionnelle et la qualité de vie des patients.

INTRODUCTION: Hereditary angioedema (HAE) is characterized by recurrent attacks of swelling of various locations and severity. An impaired quality of life of patients with HAE has been reported by several studies. We aimed at examining the overall impact of the disease in patients followed for type I HAE, particularly its impact on daily life activities, emotions and quality of life. METHODS: A questionnaire was distributed to patients consulting for type I HAE, collecting demographics, disease characteristics, impact on professional life, Hospital Anxiety and Depression score (HAD), SF-36 score and the McMaster Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR). RESULTS: The 33 patients included reported an average of 5.17 attacks over the last year. Stress was the main trigger A long-term treatment was reported by 58% of patients, 72% received specific treatment in the event of a serious attack. Sick days were reported by 33% of patients during their studies, and by 34% during work. One patient suffered from depressive symptoms and ten from anxious symptoms, according to the HAD score. The areas most impacted on the SF-36 score were general health and vitality. The mean score for MACTAR was low. CONCLUSION: HAE still has a significant impact on the daily and emotional lives of patients, despite the availability of prophylactic and crisis treatments.

Raising rare disease awareness using red flags, role play simulation and patient educators: results of a novel educational workshop on Raynaud phenomenon and systemic sclerosis.

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.

Early-onset granulomatous arthritis, uveitis and skin rash: characterization of skin involvement in Blau syndrome.

BACKGROUND: Blau syndrome (BS) is a rare monogenic autoinflammatory disease caused by NOD2 mutations. BS classically presents in early childhood as a triad of granulomatous polyarthritis, uveitis and skin involvement. Joint and ocular involvement have been characterized by several cohort studies but only very little data are available on skin lesions. OBJECTIVES: We aimed to provide a detailed clinical and microscopic analysis of skin manifestations and to study whether they may contribute to an early diagnosis. METHODS: We conducted a retrospective multicentre study in a French cohort of 21 patients diagnosed with genetically confirmed BS. RESULTS: Skin involvement was the first clinical manifestation of BS in 15/16 patients with dermatological manifestations. The presence of skin lesions was associated with significant shorter age at diagnosis (P = 0.03) and diagnostic delay (P = 0.04). Dermatological assessment allowed an earlier diagnosis (P = 0.001) and reduces the diagnostic delay (P = 0.007). Early skin lesions had a homogeneous, stereotypical clinical presentation, namely non-confluent erythematous or pigmented millimetric papules in 13/14(93%) patients. In contrast, skin lesions occurring during later disease stages had a more heterogeneous clinical presentation, including ichthyosiform dermatosis, panniculitis, livedoid lesions and vasculitis. Whatever their time of occurrence and the clinical aspect, all biopsied showed histologically presence of granuloma. CONCLUSION: Skin involvement in BS is the earliest clinical manifestation of the BS in the large majority of patients. The recognition of dermatological manifestations as granulomatous skin lesions and early dermatological expertise are the key to an early diagnosis of BS. In view of our results, it seems reasonable to propose a simplified view of skin lesions of BS in which the granuloma is the key structure.

Survival and prognosis factors in systemic sclerosis: data of a French multicenter cohort, systematic review, and meta-analysis of the literature.

BACKGROUND: Data on survival and prognosis factors in incident cohorts are scarce in systemic sclerosis (SStc). To describe survival, standardized mortality ratio (SMR), and prognosis factors in systemic sclerosis (SSc), we analyzed a multicenter French cohort of incident patients and performed a systematic review of the literature and meta-analysis. METHODS: A multicenter, French cohort study was conducted between January 1, 2000, and December 31, 2013. Patients were followed-up until July 1, 2016. A systematic review of the literature was carried out in MEDLINE and EMBASE up to July 2017. Meta-analysis was performed using all available data on SMR and hazard ratios of prognosis factors. RESULTS: A total of 625 patients (493 females, 446 lcSSc) were included. During the study period, 104 deaths (16.6%) were recorded and 133 patients were lost to follow-up. Overall survival rates at 1, 3, 5, and 10 years from diagnosis were 98.0%, 92.5%, 85.9%, and 71.7% respectively in the French cohort. Overall SMR was 5.73 (95% CI 4.68-6.94). Age at diagnosis > 60 years, diffuse cutaneous SSc, scleroderma renal crisis, dyspnea, 6-min walking distance (6MWD), forced vital capacity < 70%, diffusing capacity of the lungs for carbon monoxide < 70%, pulmonary hypertension (PH), telangiectasia, valvular disease, malignancy, anemia, and CRP > 8 mg/l were associated with a poorer survival after adjustment. Eighteen studies (11,719 patients) were included in the SMR meta-analysis and 36 studies (26,187 patients) in the prognosis factor analysis. Pooled SMR was 3.45 (95%CI 3.03-3.94). Age at disease onset, male sex, African origin, diffuse cutaneous SSc, anti-Scl70 antibodies, cardiac and renal involvement, interstitial lung disease, PH, and malignancy were significantly associated with a worse prognosis. Anti-centromere antibodies were associated with a better survival. CONCLUSIONS: Overall, our study highlights a high mortality rate in SSc patients and confirms previously described prognosis factors related to skin extension and organ involvement while identifying additional prognosis factors such as autoantibody status, telangiectasia, 6MWD, and valvular disease.

French expert opinion for the management of juvenile dermatomyositis.

A guideline group consisting of a pediatric rheumatologist, internists, rheumatologists, immunologists, a physiotherapist and a patient expert elaborated guidelines related to the management of juvenile dermatomyositis on behalf of the rare autoimmune and autoinflammatory diseases network FAI2R. A systematic search of the literature published between 2000 and 2015 and indexed in PubMed was undertaken. Here, we present the expert opinion for diagnosis and treatment in juvenile dermatomyositis.

Combined pulmonary fibrosis and emphysema in systemic sclerosis: A syndrome associated with heavy morbidity and mortality.

BACKGROUND: The syndrome of combined pulmonary fibrosis and emphysema (CPFE) primarily due to tobacco smoking has been reported in connective tissue disease, but little is known about its characteristics in systemic sclerosis (SSc). METHODS: In this retrospective multi-center case-control study, we identified 36 SSc patients with CPFE, and compared them with 72 SSc controls with interstitial lung disease (ILD) without emphysema. RESULTS: Rate of CPFE in SSc patients with CT scan was 3.6%, and 7.6% among SSc patients with ILD. CPFE-SSc patients were more likely to be male (75 % vs 18%, p < 0.0001), smokers (83 % vs 33%, p < 0.0001), and to have limited cutaneous SSc (53 % vs 24% p < 0.01) than ILD-SSc controls. No specific autoantibody was significantly associated with CPFE. At diagnosis, CPFE-SSc patients had a greater decrease in carbon monoxide diffusing capacity (DLCO 39 ± 13 % vs 51 ± 12% of predicted value, p < 0.0001) when compared to SSc-ILD controls, whereas lung volumes (total lung capacity and forced vital capacity) were similar. During follow-up, CPFE-SSc patients more frequently developed precapillary pulmonary hypertension (PH) (44 % vs 11%, p < 10-4), experienced more frequent unscheduled hospitalizations (50 % vs 25%, p < 0.01), and had decreased survival (p < 0.02 by Kaplan-Meier survival analysis) as compared to ILD-SSc controls. CONCLUSIONS: The CPFE syndrome is a distinct pulmonary manifestation in SSc, with higher morbidity and mortality. Early diagnosis of CPFE by chest CT in SSc patients (especially smokers) may result in earlier smoking cessation, screening for PH, and appropriate management.

[Exploring illness perceptions of lupus patients for a motivational environment in therapeutic education]. / Exploration des dimensions de la personne lupique pour un environnement motivationnel en éducation thérapeutique du patient.

PURPOSE: Therapeutic education (TE) intends to help patients with systemic lupus erythematosus to better understand their disease and to improve their quality of life. The objective of this study was to assess illness perceptions of the person to provide a motivational environment for TE. METHODS: Systemic lupus erythematosus patients followed in the department of internal medicine in Lille university hospital responded to a questionnaire assessing five dimensions of the person as proposed by Giordan: the cognitive (knowledge), perceptual (fatigue and pain), affective (anxious and depressive symptoms), infra-cognitive (intimate reasoning) and metacognitive (worldview) dimensions. The quality of life was also evaluated. RESULTS: One hundred and twenty-four patients (114 women (92%); mean age 44.3±14.3 years) responded to the questionnaire. Regarding the cognitive dimension: quantity of information at the time of diagnosis was considered insufficient for 57 patients (46%). The median adherence evaluated by a scale had a median 97mm [88-100]. Regarding the perceptual dimension: pain was assessed at 59mm [44-78] and fatigue at 66mm [50-79] at visual scales. Regarding the affective dimension: prevalence of anxiety symptoms was 67% (83/124) and 28% (35/124) for depressive symptoms. Regarding the infra-cognitive dimension 78 patients (63%) had an external control place. Concerning the metacognitive dimension, systemic lupus erythematosus had repercussions on professional and family life. The quality of life was impacted. CONCLUSION: Multiple dimensions of systemic lupus erythematosus patient have to be considered for an optimal motivational environment for the practice of TE.

Efficacy of anti-TNF alpha in severe and refractory major vessel involvement of Behcet's disease: A multicenter observational study of 18 patients.

OBJECTIVE: To describe the outcome and tolerance in patients treated with anti-TNFα in severe and refractory major vessel disease in Behçet's disease (BD). METHODS: A multicenter study evaluating 18 refractory BD patients with major vessel involvement [pulmonary artery (n = 4), aorta (n = 4) or peripheral artery aneurysm (n = 1) and/or pulmonary artery (n = 7), inferior vena cava (n = 5), or intra-cardiac (n = 3) thrombosis or Budd Chiari Syndrome (n = 2)] treated with anti-TNFα agents. RESULTS: Vascular remission was achieved in 16 (89%) patients. The 9 months risk of relapse was significantly higher with conventional immunosuppressants used prior anti-TNFα agents as compared to anti-TNFα therapy [OR = 8.7 (1.42-62.6), p = 0.03]. The median daily dose of corticosteroids significantly decreased at 12 months. Side effects included infection (n = 4) and pulmonary edema (n = 1). CONCLUSION: TNFα-antagonists are safe and might be associated with a decreased risk of relapse at 9 months compared to conventional immunosuppressants in BD patients with major vessels disease.

Bleeding complications and antithrombotic treatment in 264 pregnancies in antiphospholipid syndrome.

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 500 mL 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 five 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. PROMISSE Study ClinicalTrials.gov identifier: NCT00198068.

Disease severity of proliferative lupus nephritis in Maghrebians.

Objective To study the influence of Maghrebian ethnicity on lupus nephritis. Methods We retrospectively reviewed the files of a cohort of 194 patients with proliferative lupus nephritis followed in seven lupus centres belonging to three groups: Europeans living in Belgium/France (E; n = 111); Maghrebians living in Europe, in casu Belgium/France (ME; n = 43); and Maghrebians living in Morocco (MM; n = 40). Baseline presentation was compared between these three groups but complete long-term outcome data were available only for E and ME patients. Results At presentation, the clinical and pathological characteristics of lupus nephritis did not differ between E, ME and MM patients. Renal relapses were more common in ME patients (54%) than in E patients (29%) ( P < 0.01). Time to renal flare and to end-stage renal disease was shorter in ME patients compared to E patients ( P < 0.0001 and P < 0.05, respectively). While proteinuria measured at month 12 accurately predicted a serum creatinine value of less than 1 mg/dl at 7 years in E patients, this was not the case in the ME group, in whom serum creatinine at month 12 performed better. Conclusion Despite a similar disease profile at onset, the prognosis of lupus nephritis is more severe in Maghrebians living in Europe compared to native Europeans, with a higher relapse rate.

Anticoagulation withdrawal in antiphospholipid syndrome: a retrospective matched-control study.

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-ß2GP1 and triple positivity at inclusion were predictive factors for thrombotic relapse. Conversely, aspirin prescription was a protective factor against relapses. Persistence of LA, anti-ß2GP1 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-ß2GP1 and triple positivity persistence over time on the risk of relapse and the benefit of aspirin prescription when anticoagulation has been withdrawn.

[Systemic sclerosis and occupational difficulties: Results of a prospective study]. / Sclérodermie systémique et difficultés professionnelles : résultats d'une enquête prospective.

Between 9000 and 14000 people have systemic sclerosis (ScS) in France. The work is often affected. Our study aims to assess the frequency of professional difficulties (DP) of scleroderma patients, identify these DP, the symptoms involved and the solutions used. A heteroquestionnaire was offered to scleroderma patients the Lille University Hospital. Data were cross-checked with the clinical database of the National Observatory of scleroderma patients. We used 104 questionnaires of which 84% are women. A total of 62.5%, (95% CI [52.5 to 71.8]) patients had experienced DP related to SSc, 55% reported symptoms worsened at work, 41% lower efficiency and a 19% job loss. Symptoms responsible for their DP were mainly asthenia, Raynaud syndrome, arthralgias and finger ulcerations. Only 40% of patients in difficulty were initiating steps with the county home for disabled people and 45% in informing their doctor at work (MT). The MT information absence was related to a misunderstanding of possible aid in 45% of cases, 57% of patients had not found a solution, 41% of them have lost their jobs and 31% of patients in the cohort experienced a drop in income. The impact of SSc the work is important. The aid job retention devices are under-used due to lack of knowledge of steps to take and the role of MT. Taking into account the symptoms responsible for PD must be improved to participate in this retention.

Diagnosis of primary antibody and complement deficiencies in young adults after a first invasive bacterial infection.

OBJECTIVES: Screening for primary immunodeficiencies (PIDs) in adults is recommended after two severe bacterial infections. We aimed to evaluate if screening should be performed after the first invasive infection in young adults. METHODS: Eligible patients were retrospectively identified using hospital discharge and bacteriology databases in three centres during a 3-year period. Eighteen to 40-year-old patients were included if they had experienced an invasive infection with encapsulated bacteria commonly encountered in PIDs (Streptococcus pneumoniae (SP), Neisseria meningitidis (NM), Neisseria gonorrhoeae (NG), Haemophilus influenzae (HI), or group A Streptococcus (GAS)). They were excluded in case of general or local predisposing factors. Immunological explorations and PIDs diagnoses were retrieved from medical records. Serum complement and IgG/A/M testings were systematically proposed at the time of study to patients with previously incomplete PID screening. RESULTS: The study population comprised 38 patients. Thirty-six had experienced a first invasive episode and a PID was diagnosed in seven (19%): two cases of common variable immunodeficiency revealed by SP bacteraemia, one case of idiopathic primary hypogammaglobulinaemia, and two cases of complement (C6 and C7) deficiency revealed by NM meningitis, one case of IgG2/IgG4 subclasses deficiency revealed by GAS bacteraemia, and one case of specific polysaccharide antibody deficiency revealed by HI meningitis. Two patients had previously experienced an invasive infection before the study period: in both cases, a complement deficiency was diagnosed after a second NM meningitis and a second NG bacteraemia, respectively. CONCLUSION: PID screening should be considered after a first unexplained invasive encapsulated-bacterial infection in young adults.
