RESUMO
OBJECTIVE: To compare the long-term efficacy and safety of azathioprine (AZA), 18-month fixed-schedule rituximab (RTX), 18-month tailored RTX and 36-month RTX in preventing relapses in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis who achieved a complete remission after induction therapy. Patients treated with 36-month RTX received either a fixed or a tailored regimen for the first 18 months and a fixed regimen for the last 18 months (36-month fixed/fixed RTX and 36-month tailored/fixed RTX, respectively). METHODS: The Maintenance of Remission using Rituximab in Systemic ANCA-associated Vasculitis (MAINRITSAN) trials sequentially compared: 18-month fixed-schedule RTX versus AZA (MAINRITSAN); 18-month fixed-schedule RTX versus 18-month tailored-RTX (MAINRITSAN2); and extended therapy to 36 months with four additional RTX infusions after MAINRITSAN2 versus placebo (MAINRITSAN3). Patients were then followed prospectively through month 84 and their data were pooled to analyse relapses and adverse events. The primary endpoint was relapse-free survival at month 84. RESULTS: 277 patients were enrolled and divided in 5 groups: AZA (n=58), 18-month fixed-schedule RTX (n=97), 18-month tailored-RTX (n=40), 36-month tailored/fixed RTX (n=42), 36-month fixed/fixed RTX (n=41). After adjustment for prognostic factors, 18-month fixed-schedule RTX was superior to AZA in preventing major relapses at month 84 (HR 0.38, 95% CI 0.20 to 0.71). The 18-month tailored-RTX regimen was associated with an increased risk of major relapse compared with fixed-schedule regimen (HR 2.92, 95% CI 1.43 to 5.96). The risk of major relapse was similar between 36-month fixed/fixed and 18-month fixed-RTX (HR 0.69, 95% CI 0.38 to 1.25). CONCLUSIONS: According to these results, it appears that the 84-month remission rate is higher with an 18-month fixed RTX regimen compared with AZA and 18-month tailored RTX. Also, extending RTX to 36 months does not appear to reduce the long-term relapse rate compared with the 18-month fixed RTX regimen. However, as this study was underpowered to make this comparison, further prospective studies are needed to determine the potential long-term benefits of extending treatment in these patients.

Combining drugs could be an effective option for treating multirefractory ITP, that is, patients not responding to rituximab, thrombopoietin receptor agonists (TPO-RA) and splenectomy. We conducted a retrospective, multicenter, observational study including multirefractory ITP patients who received a combination of a TPO-RA and an immunosuppressive drug. We included 39 patients (67% women, median age 59 years [range 21-96]), with a median ITP duration of 57 months [3-393] and a median platelet count at initiation of 10 × 109 /L [1-35]. The combination regimen was given for a median duration of 12 months [1-103] and included eltrombopag (51%) or romiplostim (49%), associated with mycophenolate mofetil (54%), azathioprine (36%), cyclophosphamide (5%), cyclosporin (3%) or everolimus (3%). Overall, 30 patients (77%) achieved at least a response (platelet count ≥30 × 109 /L and at least doubling baseline during at least 3 months), including 24 complete responses (platelet count >100 × 109 /L during at least 3 months) with a median time to response of 30 days [7-270] and a median duration of response of 15 months [4-63]. Severe adverse event related to ITP treatment was observed in 31%. In conclusion, this study confirms that some patients with multirefractory ITP can achieve long lasting response with this combination.

Sustained response off treatment (SROT) after thrombopoietin receptor agonist (TPO-RA) discontinuation has been reported in immune thrombocytopenia (ITP). This prospective multicenter interventional study enrolled adults with persistent or chronic primary ITP and complete response (CR) on TPO-RAs. The primary end point was the proportion of patients achieving SROT (platelet count >30 × 109/L and no bleeding) at week 24 (W24) with no other ITP-specific medications. Secondary end points included the proportion of sustained CR off-treatment (SCROT, platelet count >100 × 109/L and no bleeding) and SROT at W52, bleeding events, and pattern of response to a new course of TPO-RAs. We included 48 patients with a median age of 58.5 years; 30 of 48 had chronic ITP at TPO-RA initiation. In the intention-to-treat analysis, 27 of 48 achieved SROT, 15 of 48 achieved SCROT at W24; 25 of 48 achieved SROT, and 14 of 48 achieved SCROT at W52. No severe bleeding episode occurred in patients who relapsed. Among patients rechallenged with TPO-RA, 11 of 12 achieved CR. We found no significant clinical predictors of SROT at W24. Single-cell RNA sequencing revealed enrichment of a tumor necrosis factor α signaling via NF-κB signature in CD8+ T cells of patients with no sustained response after TPO-RA discontinuation, which was further confirmed by a significant overexpression of CD69 on CD8+ T cells at baseline in these patients as compared with those achieving SCROT/SROT. Our results strongly support a strategy based on progressive tapering and discontinuation of TPO-RAs for patients with chronic ITP who achieved a stable CR on treatment. This trial was registered at www.clinicaltrials.gov as #NCT03119974.

OBJECTIVES: While chest high-resolution CT (HRCT) is correlated to severity and prognosis in asthma, it has not been studied in eosinophilic granulomatosis with polyangiitis (EGPA). Our objective is to study the prognostic value of baseline HRCT in EGPA patients. METHODS: Retrospective, multicentre observational study in three French hospitals, including EGPA patients with available chest HRCT before any systemic treatment. Two experienced radiologists blinded to clinical data evaluated HRCT images using semi-quantitative scoring. HRCT characteristics were correlated with clinical features and outcome. RESULTS: Among 46 patients, 38 (82.6%) had abnormal parenchymal findings on HRCT, including bronchial wall thickening (69.6%), mosaic perfusion (63.0%), ground-glass opacities (32.6%), bronchiectasis (30.4%), mucous plugging (21.7%) and consolidations (17.4%). Patients were clustered into three groups depending on HRCT features: ground-glass pattern, i.e. with ground-glass opacities with or without bronchial abnormalities (group 1, 28.3%), bronchial pattern (group 2, 41.3%) and extra-pulmonary pattern with no significant abnormality (group 3, 30.4%). Group 2 showed less frequent cardiac involvement (31.6 vs 46.2 and 42.9% in groups 1 and 3), more frequent positive ANCA (52.6 vs 0.0 and 14.3%) and higher eosinophil count (median 7510 vs 4000 and 4250/mm3). Group 1 showed worse prognosis with more frequent steroid-dependency (58.3 vs 11.1 and 28.6%) and requirement for mepolizumab (25.0 vs 11.1 and 7.1%). Conversely, group 2 showed a better outcome with higher rates of remission (88.9 vs 41.6 and 71.4%). CONCLUSION: Chest HRCT at diagnosis of EGPA may have prognostic value and help clinicians better manage these patients.

BACKGROUND: Adverse pregnancy outcomes in women with primary Sjögren's syndrome have only been evaluated retrospectively using heterogeneous methods and with contradictory results. We aimed to describe adverse pregnancy, delivery, and birth outcome risks in pregnant women with primary Sjögren's syndrome compared with those of a matched general population in France, and to identify factors predictive of disease flares or adverse pregnancy outcomes. METHODS: We conducted a multicentre, prospective, cohort study in France using the GR2 (Groupe de Recherche sur la Grossesse et les Maladies Rares) registry. Women from the GR2 study were eligible if they had conceived before March, 2021, had primary Sjögren's syndrome according to the American College of Rheumatology and European Alliance of Associations for Rheumatology (EULAR) 2016 classification criteria, and had an ongoing pregnancy at 12 weeks of gestation. In women who entered in the registry with pregnancies before 18 weeks of gestation, we sought to identify factors associated with primary Sjögren's syndrome flare (≥3-point increase in EULAR Sjögren's Syndrome Disease Activity Index [ESSDAI] score) or adverse pregnancy outcomes (fetal or neonatal death, placental insufficiency leading to a preterm delivery [<37 weeks of gestation], or small-for-gestational-age birthweight). A matched controlled study compared adverse pregnancy, delivery, and birth outcome rates between pregnant women with primary Sjögren's syndrome from the GR2 registry and matched controls from the general population included in the last French perinatal survey (Enquête Nationale Périnatale 2016). FINDINGS: 1944 pregnancies were identified in the GR2 cohort, of which 106 pregnancies in 96 women with primary Sjögren's syndrome were included in this analysis. The median age at pregnancy onset was 33 years (IQR 31-36). 87 (83%) of 105 pregnancies (with ethnicity data) were in White women, 18 (17%) were in Black women; 92 (90%) of 102 had previous systemic activity (ESSDAI score of ≥1; data missing in four pregnancies), and 48 (45%) of 106 had systemic activity at inclusion. Of 93 pregnancies included at week 18 of gestation or earlier, primary Sjögren's syndrome flares occurred in 12 (13%). No baseline parameters were associated with primary Sjögren's syndrome flare. Four twin pregnancies and one medical termination were excluded from the adverse pregnancy outcome analysis; of the remaining 88, adverse pregnancy outcomes occurred in six (7%). Among pregnancies in women with data for antiphospholipid antibodies (n=55), antiphospholipid antibody positivity was more frequent among pregnancies with adverse outcomes (two [50%] of four pregnancies) compared with those without adverse outcomes (two [4%] of 51 pregnancies; p=0·023). Anti-RNP antibody positivity was also more frequent among pregnancies with adverse outcomes than those without, although this was not statistically significant. In the matched controlled study, adverse pregnancy outcomes occurred in nine (9%) of 105 pregnancies in women with primary Sjögren's syndrome and 28 (7%) of the 420 matched control pregnancies; adverse pregnancy outcomes were not significantly associated with primary Sjögren's syndrome (odds ratio 1·31, 95% CI 0·53-2·98; p=0·52). INTERPRETATION: Pregnancies in women with primary Sjögren's syndrome had very good prognoses for mothers and fetuses, with no overall increase in adverse pregnancy outcome risk compared with the general population. Women with antiphospholipid antibodies or anti-RNP antibodies require close monitoring, because these factors might be associated with a higher risk of adverse pregnancy outcomes.

Aseptic abscess (AA) syndrome is a rare type of inflammatory disorder involving polymorphonuclear neutrophils (PMNs), often associated with inflammatory bowel disease (IBD). This study sought to describe the clinical characteristics and evolution of this syndrome in a large cohort. We included all patients included in the French AA syndrome register from 1999 to 2020. All patients fulfilled the criteria outlined by André et al. in 2007. Seventy-one patients were included, 37 of which were men (52.1%), of a mean age of 34.5 ± 17 years. The abscesses were located in the spleen (71.8%), lymph nodes (50.7%), skin (29.5%), liver (28.1%), lung (22.5), and rarer locations (brain, genitals, kidneys, ENT, muscles, or breasts). Of all the patients, 59% presented with an associated disease, primarily IBD (42%). They were treated with colchicine (28.1%), corticosteroids (85.9%), immunosuppressants (61.9%), and biologics (32.3%). A relapse was observed in 62% of cases, mostly in the same organ. Upon multivariate analysis, factors associated with the risk of relapse were: prescription of colchicine (HR 0.52; 95% CI [0.28-0.97]; p = 0.042), associated IBD (HR 0.57; 95% CI [0.32-0.99]; p = 0.047), and hepatic or skin abscesses at diagnosis (HR 2.14; 95% CI [1.35-3.40]; p = 0.001 and HR 1.78; 95% CI [1.07-2.93]; p = 0.024, respectively). No deaths occurred related to this disease. This large retrospective cohort study with long follow up showed that AA syndrome is a relapsing systemic disease that can evolve on its own or be the precursor of an underlying disease, such as IBD. Of all the available treatments, colchicine appeared to be protective against relapse.
RESUMO
BACKGROUND: Neurological complications of systemic lupus erythematosus (SLE) are wide and may rarely involve the peripheral nervous system. However, no case of meningoradiculitis has been well-detailed. METHODS: We report a patient with lupus-associated meningoradiculitis. RESULTS: A 57-year-old woman had SLE without neurological involvement, treated with hydroxychloroquine, methotrexate, and prednisone for 10 years. Six months after the drug discontinuation for SLE, she acutely developed gait instability, paresthesia, and neuropathic pain of the four limbs. The neurological examination and nerve conduction studies were consistent with radiculopathies. Cerebrospinal fluid (CSF) analysis showed lymphocytic meningitis. The spinal magnetic resonance imaging (MRI) revealed thickening and an enhancement of the lumbosacral roots consistent with meningoradiculitis. The extensive investigations did not argue for a differential diagnosis of SLE. The patient dramatically improved upon corticosteroids. At the last follow-up, the patient still reported mild paresthesia but the clinical examination, the CSF, and the spinal MRI were normal. CONCLUSION: This well-detailed case of meningoradiculitis broadens the spectrum of neurological complications in SLE. Early recognition of such complications might lead to efficient immunotherapy.

OBJECTIVE: The detection of somatic mutations among the genes of myeloid cells in asymptomatic patients-defining clonal haematopoiesis of indeterminate potential (CHIP)-is associated with a predisposition to cardiovascular events (CVEs) in the general population. We aimed to determine whether CHIP was associated with CVEs in SLE patients. METHODS: The study is an ancillary study of the randomized, double-blind, placebo-controlled, multicentre PLUS trial conducted from June 2007 through August 2010 at 37 centres in France, involving 573 SLE patients. The search for somatic mutations by high-throughput sequencing of 53 genes involved in clonal haematopoiesis was performed on genomic DNA collected at PLUS inclusion. CHIP prevalence was assessed in SLE and in a retrospective cohort of 479 patients free of haematological malignancy. The primary outcome was an incident CVE in SLE. RESULTS: Screening for CHIP was performed in 438 SLE patients [38 (29-47) years, 91.8% female]. Overall, 63 somatic mutations were identified in 47 patients, defining a CHIP prevalence of 10.7% in SLE. Most SLE patients (78.7%) carried a single mutation. Most variants (62.5%) were located in the DNMT3A gene. CHIP frequency was related to age and to age at SLE diagnosis, and was associated with a lower frequency of aPLs. CHIP occurred >20 years earlier (P < 0.00001) in SLE than in controls. The detection of CHIP at inclusion was not found to be associated with occurrence of CVEs during follow-up [HR = 0.42 (0.06-3.21), P = 0.406]. CONCLUSION: The prevalence of CHIP is relatively high in SLE for a given age, but was not found to be associated with incident CVEs.

OBJECTIVE: The optimal induction therapy for severe glomerulonephritis of ANCA-associated vasculitis (AAV) is debated. We compared the efficacy of glucocorticoid and rituximab (RTX) or CYC induction therapy for severe AAV-related glomerulonephritis and evaluated the potential benefit of plasma exchange (PE) as adjunct therapy to CYC. METHODS: This retrospective, multicentre study included AAV patients with severe renal active disease (serum creatinine level ≥350 µmol/l and/or estimated glomerular filtration ratio ≤15 ml/min/1.73 m2). Propensity-score analysis was used to adjust for potential confounders. RESULTS: Between 2005 and 2017, 153 patients with AAV-related glomerulonephritis were studied (96 [60%] men; mean [s.d.] age 63 [13.1] years): 19 (12%) were treated with RTX and 134 (88%) with CYC. Remission rates did not differ between RTX- and CYC-treated groups. Although more patients with RTX than CYC were dialysis-free at month (M) 12 (79% vs 68%), the difference was not significant after adjustment. Among 134 patients with CYC-treated glomerulonephritis, 76 (57%) also had PE. M3 and M6 remission rates were comparable for weighted CYC groups with or without PE. For weighted groups, the dialysis-free survival rate with CYC was higher with than without PE at M6 (72% vs 64%; odds ratio 2.58) and M12 (74% vs 60%; odds ratio 2.78) reaching statistical significance at M12. CONCLUSION: We could not find any difference between RTX and CYC as induction therapy for patients with severe AAV-related glomerulonephritis. In patients receiving CYC induction regimen, the addition of PE conferred short-term benefits with higher dialysis-free rate at M12.

OBJECTIVES: The specific roles of remission status, lupus low disease activity state (LLDAS), and damage accrual on the prognosis of pregnancies in women with SLE are unknown. We analysed their impact on maternal flares and adverse pregnancy outcomes (APOs). METHODS: We evaluated all women (≥18 years) with SLE enrolled in the prospective GR2 study with an ongoing singleton pregnancy at 12 weeks (one pregnancy/woman). Several sets of criteria were used to define remission, disease activity and damage. APOs included: foetal/neonatal death, placental insufficiency with preterm delivery and small-for-gestational-age birth weight. First trimester maternal and disease features were tested as predictors of maternal flares and APOs. RESULTS: The study included 238 women (98.3% on hydroxychloroquine (HCQ)) with 230 live births. Thirty-five (14.7%) patients had at least one flare during the second/third trimester. At least one APOs occurred in 34 (14.3%) women. Hypocomplementemia in the first trimester was the only factor associated with maternal flares later in pregnancy (P=0.02), while several factors were associated with APOs. In the logistic regression models, damage by SLICC-Damage Index [odds ratio (OR) 1.8, 95% CI: 1.1, 2.9 for model 1 and OR 1.7, 95% CI: 1.1, 2.8 for model 2] and lupus anticoagulant (LA, OR 4.2, 95% CI: 1.8, 9.7 for model 1; OR 3.7, 95% CI: 1.6, 8.7 for model 2) were significantly associated with APOs. CONCLUSION: LA and damage at conception were predictors of APOs, and hypocomplementemia in the first trimester was associated with maternal flares later in pregnancy in this cohort of pregnant patients mostly with well-controlled SLE treated with HCQ.

OBJECTIVE: The aim of this study was to describe the efficacy and safety of rituximab and MTX (RTX/MTX) combination therapy in ANCA-associated vasculitides (AAV). METHODS: A retrospective French nationwide study was conducted in patients with AAV who received RTX/MTX combination therapy for persistently active disease. RESULTS: Seventeen patients were included. All patients had granulomatosis with polyangiitis (GPA), with positive ANCA in 76% of them, mainly with PR3-ANCA specificity. Sixteen patients (94%) had priorly failed to achieve remission with RTX and 11 (65%) with CYC. Patients had experienced a median of 3 (2-4) flares. Manifestations requiring RTX/MTX combination therapy were subglottic or bronchial stenosis in 6 patients (35%), orbital mass in 6 (35%), disabling ENT involvement in 2 (12%), and epiduritis and pachymeningitis in 1 case (6%) each. The median follow-up duration for the RTX/MTX combination therapy was 11 months (11-26 months). At 6 months, global response had been achieved in 15 patients (88%), including partial response in 11 (65%) and complete response in 4 (24%). At last evaluation, global response had been achieved in 16 patients (94%). Seven patients (41%) experienced severe adverse events (grade 3 or 4), including infections in 4 (24%) and hepatitis in 2 (12%). Combination therapy was withdrawn in 4 patients (24%), but never for safety concerns. In contrast, the MTX dose was decreased in 2 patients (12%) because of adverse events. One patient died of an unknown cause. CONCLUSION: RTX/MTX combination therapy could be an effective salvage therapy to treat persistently active GPA with granulomatous manifestations, with an acceptable safety profile.

Data about the presentation and the management of primary immune thrombocytopenia (ITP) in very elderly patients (VEPs; aged ≥80 years) are lacking. The aim of the present study was to describe ITP in this subgroup. The data source was the prospective CARMEN-France registry. Patients included between 2013 and 2018 were selected. ITP presentation and management in VEPs was compared to elderly patients (EPs; aged 65-79 years). We assessed factors associated with bleeding at ITP onset in VEPs. Of 541 patients, 184 were included: 87 in the VEP group and 97 in the EP group. The mean age was 85·7 years in the VEP group. Comorbidities were more frequent in the VEP group (67·4% vs. 47·9%). The median platelet count at ITP onset was similar but severe bleeding tended to be more frequent in VEPs (10·3% vs. 4·1%, P = 0·1) as well as mortality. Exposure to ITP drugs, response to first-line treatment, need of second-line treatment, evolution towards persistency, occurrence of bleeding, infection and thrombosis did not differ between groups. In VEPs, factors associated to bleeding were female sex [odds ratio (OR) 4·75, 95% confidence interval (CI) 1·31-17·32] and platelet count of <20 × 109 /l (OR 10·05, 95% CI 4·83-67·39). Exposure to anticoagulants was strongly associated with severe bleeding (OR 7·61, 95% CI 1·77-32·83).

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.
