ABSTRACT
OBJECTIVE: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) primarily affects small vessels. Large-vessel involvement (LVI) is rare. We aimed to describe the characteristics of LVI, to identify associated risk factors, and to describe its therapeutic management. METHODS: This multicenter case-control (1:2) study included patients with AAV according to the ACR/EULAR classification and LVI as defined by the Chapel Hill nomenclature, together with controls matched for age, sex, and AAV type. RESULTS: We included 26 patients, 15 (58 %) of whom were men, with a mean age of 56.0 ± 17.1 years. The patients had granulomatosis with polyangiitis (n = 20), or microscopic polyangiitis (n = 6). The affected vessels included the aorta (n = 18; 69 %) supra-aortic trunks (n = 9; 35 %), lower-limb arteries (n = 5; 19 %), mesenteric arteries (n = 5; 19 %), renal arteries (n = 4; 15 %), and upper-limb arteries (n = 2; 8 %). Imaging showed wall thickening (n = 10; 38 %), perivascular inflammation (n = 8; 31 %), aneurysms (n = 5; 19 %), and stenosis (n = 4; 15 %). Comparisons with the control group revealed that LVI was significantly associated with neurological manifestations (OR=3.23 [95 % CI: 1.11-10.01, p = 0.03]), but not with cardiovascular risk factors (OR=0.70 [95 % CI: 0.23-2.21, p = 0.60]), or AAV relapse (OR=2.01 [95 % CI: 0.70-5.88, p = 0.16]). All patients received corticosteroids, in combination with an immunosuppressant in 24 (92 %), mostly cyclophosphamide (n = 10, 38 %) or rituximab (n = 9, 35 %). CONCLUSION: Regardless of distinctions based on vessel size, clinicians should consider LVI as a potential manifestation of AAV, with the aorta commonly affected. The risk of developing LVI appears to be greater for clinical phenotypes of AAV with neurological involvement. Standard AAV treatment can be used to manage LVI.

INTRODUCTION: Pulmonary arterial hypertension (PAH) is a severe complication of connective tissue disease (CTD). Data on use of prostanoids in this particular subset of patients are lacking. We aimed to describe the characteristics of patients with PAH-CTD treated with prostanoids and the outcomes under treatment. METHODS: In this multicenter retrospective study, all patients treated with prostanoids since 2006 were included. Data on PAH and CTD were collected at the time of prostanoid introduction and under treatment. RESULTS: Twenty-one patients were included, of whom 20 (95%) had limited cutaneous systemic sclerosis. Nineteen patients were treated with oral monotherapy or combination before addition of prostanoid. Treprostinil was the most used molecule (57% of patients). At the time of prostanoid introduction, 90% of patients were considered at high risk for death. Among patients who had right heart catheterization during follow-up, there was no significant difference in haemodynamics. No extrarespiratory worsening of the CTD was reported. The 1-year survival under prostanoid was 62%. In univariate analysis, NYHA functional class was associated with survival under treatment. CONCLUSION: This study provides original data on use of prostanoids in a cohort consisting mainly of systemic sclerosis. It underlines the difficulty to achieve a standardized assessment in this subset of patients. Safety profile was comparable with data reported in idiopathic PAH.

Objective: To compare the clinical presentation and outcome of giant cell arteritis (GCA)-related aortitis according to the results of temporal artery biopsy (TAB).Method: Patients with GCA-related aortitis diagnosed between 2000 and 2017, who underwent TAB, were retrospectively included from a French multicentre database. They all met at least three American College of Rheumatology criteria for the diagnosis of GCA. Aortitis was defined by aortic wall thickening > 2 mm on computed tomography scan and/or an aortic aneurysm, associated with an inflammatory syndrome. Patients were divided into two groups [positive and negative TAB (TAB+, TAB-)], which were compared regarding aortic imaging characteristics and aortic events, at aortitis diagnosis and during follow-up.Results: We included 56 patients with TAB+ (70%) and 24 with TAB- (30%). At aortitis diagnosis, patients with TAB- were significantly younger than those with TAB+ (67.7 ± 9 vs 72.3 ± 7 years, p = 0.022). Initial clinical signs of GCA, inflammatory parameters, and glucocorticoid therapy were similar in both groups. Coronary artery disease and/or lower limb peripheral arterial disease was more frequent in TAB- patients (25% vs 5.3%, p = 0.018). Aortic wall thickness and type of aortic involvement were not significantly different between groups. Diffuse arterial involvement from the aortic arch was more frequent in TAB- patients (29.1 vs 8.9%, p = 0.03). There were no differences between the groups regarding overall, aneurism-free, relapse-free, and aortic event-free survival.Conclusion: Among patients with GCA-related aortitis, those with TAB- are characterized by younger age and increased frequency of diffuse arterial involvement from the aortic arch compared to those with TAB+, without significant differences in terms of prognosis.

We report a case of a 76-year-old woman with isolated unilateral Raynaud phenomenon revealing giant-cell arteritis with diffuse arterial lesions and bilateral renal artery stenosis. Doppler ultrasonography showed bilateral stenosis of the subclavian and axillary arteries. Angio-CT PET enlightened diffuse arterial lesions, mainly involving the aorta and the brachial and femoral arteries as well as bilateral renal ostial stenosis with right kidney ischemia. Diagnosis of giant-cell arteritis was made on the temporal artery biopsy. Corticosteroid therapy led to rapid clinical and radiological improvement. Clinical manifestations of giant-cell arteritis may be atypical. Diffuse arterial disease may exist in the absence of cephalic symptoms or significant inflammatory biological features. Ostial renal artery stenosis may induce potentially threatening renal ischemia.

OBJECTIVES: Ischaemic digital ulcers (DUs) are a common complication of systemic sclerosis (SSc). This study aimed to characterize patients with SSc and ongoing DUs treated with the endothelin receptor antagonist bosentan in clinical practice in France. METHOD: An observational, retrospective, longitudinal study was conducted in 10 French expert centres. Medical records from randomly selected adult SSc patients who received treatment with bosentan for DU prevention from March 2007 to December 2010 were analysed. The primary objective was to determine the profile of patients at treatment initiation. Secondary objectives were to monitor bosentan dosing, treatment schedule, and reasons for treatment termination. RESULTS: The study included 89 patients (mean age 52 years, 69% female, 44% diffuse cutaneous SSc). At bosentan treatment initiation, the mean duration of Raynaud's phenomenon was 15 ± 12 years, and the mean time since first episode with DU was 6.5 ± 7 years. Most patients had a history of at least two episodes with DUs, separated by < 12 months (61%), and had received intravenous iloprost (63%). Previous DU complications included auto-amputation (8%), surgical amputation (6%), osteitis (6%), and gangrene (4.5%). Active smokers (25%) had a history of significantly more surgical amputation (p = 0.004) and osteitis (p = 0.004) than non-smokers. At least one active DU at bosentan initiation was detected in 82% of patients. Bosentan was used according to prescription guidelines and was well tolerated; six patients (7%) withdrew from treatment because of raised liver enzymes. CONCLUSIONS: Patients treated with bosentan for DU prevention in France have severe, refractory, ongoing ulcerative disease. Active smoking was correlated to a history of DU complications. Tolerance of bosentan was comparable to previous studies.

Lenalidomide is an immunomodulating drug structurally similar to thalidomide. It is indicated for patients with relapsing or refractory multiple myeloma in combination with dexamethasone, and for patients with myelodysplastic syndromes associated with a deletion 5q cytogenetic abnormality. It is also used to treat other myelodysplastic syndromes such as myelofibrosis and lymphoma. We report a case of organizing pneumonia leading to acute respiratory distress syndrome (ARDS) after long-term administration of lenalidomide, along with a review of the literature.

Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) treatment strategy is based on immunosuppressive agents. Little information is available concerning mycophenolic acid (MPA) and the area under the curve (AUC) in patients treated for AAV. We evaluated the variations in pharmacokinetics for MPA in patients with AAV and the relationship between MPA-AUC and markers of the disease. MPA blood concentrations were measured through the enzyme-multiplied immunotechnique (C(0), C(30), C(1), C(2), C(3), C(4), C(6) and C(9)) to determine the AUC. Eighteen patients were included in the study. The median (range) MPA AUC(0-12) was 50·55 (30·9-105·4) mg/h/l. The highest coefficient of determination between MPA AUC and single concentrations was observed with C(3) (P < 0·0001) and C(2) (P < 0·0001) and with C(4) (P < 0·0005) or C(0) (P < 0·001). Using linear regression, the best estimation of MPA AUC was provided by a model including C(30), C(2) and C(4): AUC = 8·5 + 0·77 C(30) + 4·0 C(2) + 1·7 C(4) (P < 0·0001). Moreover, there was a significant relationship between MPA AUC(0-12) and lymphocyte count (P < 0·01), especially CD19 (P < 0·005), CD8 (P < 0·05) and CD56 (P < 0·05). Our results confirm the interindividual variability of MPA AUC in patients treated with MMF in AAV and support a personalized therapy according to blood levels of MPA.

The pleuro-pulmonary signs of ankylosing spondylitis are generally asymptomatic, typically represented by biapical lung fibrosis. To our knowledge, the severe bronchiolitis which is sometimes observed in other spondyloarthropathies has not been described in ankylosing spondylitis. We report two cases of severe chronic bronchiolitis in ankylosing spondylitis patients. Their clinical and radiological presentation were similar, characterized by progressive deterioration of stage III-IV dyspnea, non-reversible obstructive ventilatory defect, and CT scan showing air trapping with mosaic attenuation and ground-glass opacity in expiration. Lung biopsies confirmed the diagnosis of severe follicular bronchiolitis in one patient and constrictive bronchiolitis is suspected in the other. Only the patient with follicular bronchiolitis responded positively to treatment with low doses of macrolides.

Cardiopulmonary involvement in adult-onset Still's disease is not as common as cutaneous and articular involvement. Pleuropericarditis is the most frequent thoracic manifestation. Although difficult, diagnosis of other thoracic manifestations, which may reveal the disease, is crucial, due to the high risk to life and the efficacy of new immunosuppressive agents. The pathophysiology involves essentially immunological factors, Still's disease being increasingly seen as an autoimmune inflammatory disease. Pro-inflammatory cytokines such as interleukine (IL) 1, 6 and 18 play a crucial role in macrophage activation, which is central in the pathophysiology of adult Still's disease. The classification of cardiopulmonary manifestations is based on anatomy. Cardiac lesions may involve all the tissues of the heart and the pulmonary arteries. Respiratory lesions may involve the pleura, the lung parenchyma (organizing pneumonitis, infiltrative lung disease, alveolar damage, amyloidosis), and the respiratory muscles, including the diaphragm. Finally, some manifestations may be provoked by the treatment itself. Steroids, the first-line treatment, are very effective in pleuropericarditis. Methotrexate used to be prescribed when steroids failed, but biotherapies such as IL1 and IL6 inhibitors have transformed the prognosis of forms resistant to these drugs.

BACKGROUND: The aims of the present study were to determine both clinical manifestations and outcome of anti-PL7 patients with antisynthetase syndrome (ASS). METHODS: The medical records of 15 consecutive anti-PL7 patients with biopsy proven ASS were retrospectively analyzed without prior selection. RESULTS: Anti-PL7 patients exhibited polymyositis (n=14) and dermatomyositis (n=1); extra-pulmonary manifestations of ASS included: Raynaud's phenomenon (40%), mechanic's hands (33.3%), joint impairment (26.7%), pericardial effusion (20%) and esophageal/gastrointestinal involvement (20%). The outcome of myositis was as follows: remission/improvement (91.7%) and deterioration (8.3%). Fourteen patients (93.3%) experienced interstitial lung disease (ILD). ILD preceded ASS diagnosis (n=5), was identified concomitantly with ASS (n=8) and occurred after ASS diagnosis (n=1). Patients could be divided into 3 groups according to their presenting lung manifestations: acute onset of lung disease (n=1), progressive onset of lung signs (n=11) and asymptomatic patients exhibiting abnormalities consistent with ILD on PFT and HRCT-scan (n=2). No patient had resolution of ILD, whereas 64.3% and 35.7% experienced improvement and deterioration of ILD, respectively. ILD resulted in respiratory insufficiency requiring O2 therapy in 14.3% of cases. Two patients died. Predictive parameters of ILD deterioration were: DLCO<45% at ILD diagnosis and HRCT-scan pattern of usual interstitial pneumonia (UIP). CONCLUSION: Our series mainly underscores that ILD is frequent in anti-PL7 patients, leading to high morbidity. Our study further suggests that patients with predictive factors of ILD deterioration may require more aggressive therapy, especially the group of patients with DLCO<45% at ILD diagnosis and UIP pattern on HRCT-scan.

BACKGROUND: Imatinib mesylate is a potent inhibitor of platelet-derived growth factor and transforming growth factor-ß signalling pathways which may play a role in systemic sclerosis (SSc)-associated skin changes. OBJECTIVES: We aimed primarily at assessing the efficacy of imatinib mesylate in scleroderma skin fibrosis. METHODS: We performed a phase II double-blinded trial on patients with scleroderma with either morphoea involving > 20% of body surface area or SSc with extensive skin involvement: modified Rodnan Skin Score (mRSS) ≥ 20/51. Each patient was randomized to receive either imatinib mesylate 400 mg or placebo daily for a total of 6 months, and then was followed up 6 months after therapy discontinuation. Skin fibrosis was assessed by mRSS and measurement of the dermal thickness using skin biopsies performed at inclusion and at 6 months of treatment. In addition, quality of life (Dermatology Life Quality Index and modified Health Assessment Questionnaire for Scleroderma) was recorded at each visit, and pulmonary function before and after intervention. RESULTS: Twenty-eight patients were included in the study with a mean age of 48·9 years (range 30-71): 25 had a diagnosis of a SSc and three of diffuse cutaneous scleroderma. Demographic data, frequency of organ involvement of SSc and mRSS were comparable between groups. At 6 months, the proportion of variation of mRSS from inclusion was not statistically significantly different between the two groups (median +0·10 in imatinib group vs. -0·16 in placebo group, P = 0·098). Similarly, changes in dermal thickness, quality of life and diffusion capacity for carbon monoxide were not significantly different between groups. CONCLUSIONS: This study failed to demonstrate the efficacy of imatinib 400 mg daily to improve skin fibrosis of diffuse scleroderma after 6 months of treatment based on validated outcome measurements.

The aims of the present study were to: compare the characteristics between antisynthetase syndrome (ASS) patients with anti-Jo1 antibody and those with anti-PL7/PL12 antibody. The medical records of 95 consecutive patients with ASS were reviewed. Seventy-five of these patients had anti-Jo1 antibody; the other patients had anti-PL7 (n=15) or anti-PL12 (n=5) antibody. At ASS diagnosis, the prevalence of myalgia (p=0.007) and muscle weakness (p=0.02) was significantly lower in the group of anti-PL7/PL12-positive patients than in those with anti-Jo1 antibody; median value of CK (p=0.00003) was also lower in anti-PL7/PL12 patients. Anti-Jo1 positive patients developed more rarely myositis resolution (21.3% vs. 46.2%); in addition, the overall recurrence rate of myositis was higher in anti-Jo1 positive patients than in patients with anti-PL7/PL12 antibody (65.9% vs. 19.4%). Anti-Jo1-positive patients, compared with those with anti-PL7/PL12 antibody, more often experienced: joint involvement (63.3%vs. 40%) and cancer (13.3% vs. 5%). By contrast, anti-PL7/PL12 positive patients, compared with those with anti-Jo1 antibody, more commonly exhibited: ILD (90% vs. 68%); in anti-PL7/PL12 positive patients, ILD was more often symptomatic at diagnosis, and led more rarely to resolution of lung manifestations (5.6% vs. 29.4%). Finally, the group of anti-PL7/PL12 positive patients more commonly experienced gastrointestinal manifestations related to ASS (p=0.02). Taken together, although anti-Jo1 positive patients with ASS share some features with those with anti-PL7/PL12 antibody, they exhibit many differences regarding clinical phenotype and long-term outcome. Our study underscores that the presence of anti-Jo1 antibody results in more severe myositis, joint impairment and increased risk of cancer. On the other hand, the presence of anti-PL7/PL12 antibody is markedly associated with: early and severe ILD, and gastrointestinal complications. Thus, our study interestingly indicates that the finding for anti-Jo1 and anti-PL7/PL12 antibodies impacts both the long-term outcome and prognosis of patients with ASS.

Hypothesizing a pathophysiological role of anti-topoisomerase I antibodies (anti-topo I) through autoantibody-dependent cell-mediated cytotoxicity (ADCC) and cytotoxic effectors expressing receptors for the Fc portion of IgG in systemic sclerosis (SSc), 267 SSc patients (56 with anti-topo I and 102 with anti-centromere antibodies (ACA)) were genotyped for the functional FCGR3A-V158F polymorphism. A descriptive analysis of patients according to their clinical and immunological status and FCGR3A-158 V/F genotypes was performed using multiple correspondence analysis. This descriptive analysis revealed an association between the FCGR3A-158 VV genotype and the presence of anti-topo I. By contrast, no relationship was found between FCGR3A polymorphism and the presence of ACA. SSc patients with anti-topo I appear to be more frequently homozygous for the high-affinity FcγRIIIA-coding allele, suggesting that some autoantibodies may be pathogenic through ADCC.
