RESUMO
Data about the impact of Belimumab on corticosteroid sparing in real life are scarce. To assess the corticosteroid-sparing effect among patients with systemic lupus erythematosus (SLE) treated with Belimumab in real-life settings. Multicentric observational retrospective study including patients with SLE and having received Belimumab for at least 6 months between 2011 and 2020, in eight French hospitals. "Low dose" referred to patients receiving up to 7.5 mg of prednisone a day and "Very low dose" to those receiving strictly ≤ 5 mg prednisone a day The primary endpoint was the reduction of daily prednisone dose after six months of Belimumab. The secondary endpoint was a change in the proportion of patients with low or very low dose of prednisone as well as those without prednisone during the Belimumab course. Censoring occurred for patients who stopped Belimumab. Bivariate analyses were performed using the Wilcoxon signed-rank test. The threshold for statistical significance was set at p < 0.05. Thirty patients were included. All were female with a median age of 38 years. A significant reduction in prednisone dose was observed at month 6 (10 [7-20] vs 6.75 [2-9] mg, p < 0.0001), continued until month 12 (10 [7-20] mg vs 5 [0-7.12] mg, p < 0.001) and was sustained until month 24. The proportion of patients with very low dose of prednisone and those without prednisone progressively increased during the Belimumab course. Introducing Belimumab in patients with SLE, in real-life conditions, is associated with early and sustained corticosteroid-sparing effect.
RESUMO
BACKGROUND: Polyclonal hypergammaglobulinaemia (PH) represents a classic diagnosis problem in internal medicine. However, there is no consensus threshold for PH. The aim of this study was to define a threshold for PH. METHODS: We conducted a retrospective multicentric study using laboratory biological databases between 1 January 2016 and 31 December 2016 in two university hospitals and one non-university hospital. All patients 18 years old or over and with at least one serum protein electrophoresis (SPE) available in 2016 were included. Exclusion criteria were monoclonal, biclonal, or oligoclonal spikes or, in case of hypogammaglobulinaemia, proven free light chain gammopathy. The main endpoint was to define the threshold values for PH in this population. Another objective was to define the 95th percentile of the distribution. RESULTS: 20 766 SPEs were included in this cohort. The PH threshold on 95th percentile was 18.9 g/L. The threshold varied according to geographical areas. CONCLUSIONS: This is the first study to scientifically define a PH threshold. The main limitation is that our threshold is only biological. The study was not designed to associate this threshold with a clinically active disease. In conclusion, while the 19 g/L cut-off seems the most relevant threshold, but it will need to be validated by prospective studies.

Rationale: The relationship between the initial treatment strategy and survival in pulmonary arterial hypertension (PAH) remains uncertain. Objectives: To evaluate the long-term survival of patients with PAH categorized according to the initial treatment strategy. Methods: A retrospective analysis of incident patients with idiopathic, heritable, or anorexigen-induced PAH enrolled in the French Pulmonary Hypertension Registry (January 2006 to December 2018) was conducted. Survival was assessed according to the initial strategy: monotherapy, dual therapy, or triple-combination therapy (two oral medications and a parenteral prostacyclin). Measurements and Main Results: Among 1,611 enrolled patients, 984 were initiated on monotherapy, 551 were initiated on dual therapy, and 76 were initiated on triple therapy. The triple-combination group was younger and had fewer comorbidities but had a higher mortality risk. The survival rate was higher with the use of triple therapy (91% at 5 yr) as compared with dual therapy or monotherapy (both 61% at 5 yr) (P < 0.001). Propensity score matching of age, sex, and pulmonary vascular resistance also showed significant differences between triple therapy and dual therapy (10-yr survival, 85% vs. 65%). In high-risk patients (n = 243), the survival rate was higher with triple therapy than with monotherapy or dual therapy, whereas there was no difference between monotherapy and double therapy. In intermediate-risk patients (n = 1,134), survival improved with an increasing number of therapies. In multivariable Cox regression, triple therapy was independently associated with a lower risk of death (hazard ratio, 0.29; 95% confidence interval, 0.11-0.80; P = 0.017). Among the 148 patients initiated on a parenteral prostacyclin, those on triple therapy had a higher survival rate than those on monotherapy or dual therapy. Conclusions: Initial triple-combination therapy that includes parenteral prostacyclin seems to be associated with a higher survival rate in PAH, particularly in the youngest high-risk patients.

RESUMO
OBJECTIVES: In severe rapidly progressive SSc, autologous haematopoietic stem cell transplantation (AHSCT) allows significant improvements in overall and event-free survival. We undertook this study to identify, appraise and synthesize the evidence on health-related quality of life (HRQoL) before and after AHSCT for SSc. METHODS: We performed a systematic review of the literature, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, in PubMed and ScienceDirect from database inception to 1 February 2019. All articles with original HRQoL data were selected. RESULTS: The search identified 1080 articles, of which 8 were selected: 3 unblinded randomized controlled trials [American Scleroderma Stem Cell versus Immune Suppression Trial (ASSIST), Autologous Stem Cell Transplantation International Scleroderma, Scleroderma: Cyclophosphamide or Transplantation), 3 uncontrolled phase I or II trials and 2 cohort studies. HRQoL data from 289 SSc patients treated with AHSCT and 125 treated with intravenous CYC as a comparator with median 1.25-4.5 years follow-up were included. HRQoL was evaluated with the HAQ Disability Index (HAQ-DI; 275 patients), the 36-item Short Form Health Survey (SF-36; 249 patients) and the European Quality of Life 5-Dimensions questionnaire (EQ-5D; 138 patients). The quality of the studies was moderate to low. AHSCT was associated with significant improvement in the HAQ-DI (P = 0.02-<0.001), SF-36 Physical Component Summary score (P = 0.02-<0.0001) and EQ-5D index-based utility score (P < 0.001). The SF-36 Mental Component Summary score improved in the ASSIST (n = 19) and one small retrospective cohort (n = 30 patients, P = 0.005) but did not improve significantly in 2 randomized controlled trials (n = 200 patients, P = 0.1-0.91). CONCLUSION: AHSCT in severe SSc patients is associated with significant and durable improvement in physical HRQoL.

OBJECTIVE: This study aimed to describe severe infections in patients treated with tocilizumab for systemic diseases other than rheumatoid arthritis. METHODS: Data from patients receiving at least 2 doses of tocilizumab for systemic diseases other than rheumatoid arthritis between January 1, 2012, and July 1, 2020, in the region Poitou-Charentes (France) were retrospectively collected from medical records. Psoriatic arthritis and systemic juvenile idiopathic arthritis were also excluded as usually treated with similar modalities to rheumatoid arthritis. RESULTS: Of 37 patients, mainly suffering from giant cell arteritis, 25 patients (68%) had at least 1 infectious event and 15 severe infections occurred in 6 patients (3.2/100 patient-years), mainly bacterial. Lower respiratory tract and skin were the main sites. Severe bacterial infections were associated with a marked biological inflammatory syndrome, even under a cycle of administration of tocilizumab. Two severe zonas and 1 severe diverticulitis occurred. No tuberculosis or viral hepatitis reactivation was observed. CONCLUSION: The incidence rate of severe infections was 3.2/100 patient-years and seems lower than that reported in rheumatoid arthritis. C-reactive protein dosage could be helpful for the diagnosis of bacterial infectious adverse events in patients on tocilizumab. Further larger studies are needed to confirm these results to assess potential risk factors for severe infections.
RESUMO
Immune checkpoint inhibitors (ICIs) have become the standard of care for several types of cancer due to their superiority in terms of survival benefits in first- and second-line treatments compared to conventional therapies, and they present a better safety profile (lower absolute number of grade 1-5 adverse events), especially if used in monotherapy. However, the pattern of ICI-related adverse events is totally different, as they are characterized by the development of specific immune-related adverse events (irAEs) that are unique in terms of the organs involved, onset patterns, and severity. The decision to resume ICI treatment after its interruption due to irAEs is challenged by the need for tumor control versus the risk of occurrence of the same or different irAEs. Studies that specifically assess this point remain scarce, heterogenous and mostly based on small samples of patients or focused only on the recurrence rate of the same irAE after ICI resumption. Moreover, patients with grade ≥3 irAEs were excluded from many of these studies. Herein, we provide a narrative review on the field of safety of ICI resumption after interruption due to irAE(s).
RESUMO
Data on venous thromboembolic events (VTEs) in patients receiving immune checkpoint inhibitors (ICIs) are scarce and conflicting. This study investigated the risk of reporting VTEs associated with ICIs in comparison with all other anticancer drugs. The World Health Organization pharmacovigilance database (VigiBase), comprising >30 million individual case safety reports, was queried. All reports on patients with cancer, involving at least one anticancer drug as a suspect or interacting drug and registered from January 1, 2008, to May 31, 2021, were included. The association between ICIs and the risk of reporting VTEs was estimated using the reporting odds ratio (ROR) as a measure of disproportionality with all other anticancer drugs as comparators. RORs were estimated as crude and adjusted RORs for age, sex, and other medications (excluding anticancer drugs) associated with risk of VTEs. Among 1,196 patients experiencing VTEs after ICI treatment, the median age was 65 years and 57.6% were men. Anti-PD-1 agents (62.5%) were the most frequently reported. ICIs were not associated with higher reporting of VTEs when compared with other anticancer drugs (crude ROR 0.63, 95% confidence interval (CI) 0.60 to 0.67 and adjusted ROR 0.70, 95% CI 0.65-0.74). No signal of disproportionate reporting was found when considering each class of ICIs. In conclusion, ICIs were not associated with higher reporting of VTEs, in comparison with all other anticancer drugs in a large-scale pharmacovigilance database. Owing to the limitations inherent to pharmacovigilance studies, prospective studies, including an adequate comparison group, are needed to assess the risk of VTEs in ICI-treated patients.

Immune checkpoint inhibitor (ICI)-related cytopenias have been poorly described. This study aimed to further characterize ICI-related cytopenias, using the French pharmacovigilance database. All grade ≥ 2 hematological adverse drug reactions involving at least one ICI coded as suspected or interacting drug according to the World Health Organization criteria and reported up to 31 March 2022, were extracted from the French pharmacovigilance database. Patients were included if they experienced ICI-related grade ≥ 2 cytopenia. We included 68 patients (75 ICI-related cytopenias). Sixty-three percent were male, and the median age was 63.0 years. Seven patients (10.3%) had a previous history of autoimmune disease. Immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA) were the most frequently reported (50.7% and 25.3%, respectively). The median time to onset of ICI-related cytopenias was 2 months. Nearly half were grade ≥ 4, and three patients died from bleeding complications of refractory ITP and from thromboembolic disease with active AIHA. Out of 61 evaluable responses, complete or partial remission was observed after conventional treatment in 72.1% of ICI-related cytopenias. Among the 10 patients with ICI resumption after grade ≥ 2 ICI-related cytopenia, three relapsed. ICI-related cytopenias are rare but potentially life-threatening. Further studies are needed to identify risk factors of ICI-related cytopenias.
RESUMO
BACKGROUND: Trephine bone marrow biopsy (BMB) in internal medicine has only been studied in fever of unknown origin and inflammation of unknown origin. The aim was to assess BMB diagnostic yield according to main indications and patient characteristics in internal medicine. Quality of BMB and contribution of bone marrow aspiration (BMA) to BMB were also analyzed. METHODS: BMB performed in the internal medicine department of Poitiers university hospital between January 2000 and December 2015 were retrospectively analyzed. Patient characteristics, BMB indications, quality parameters, and results were collected from medical records. Contributive BMB was BMB allowing accurate final diagnosis. Diagnostic yield was the proportion of contributive BMB among total BMB performed. RESULTS: A total of 468 BMBs conducted for primary diagnostic purpose from 468 patients were analyzed. Cytopenia(s) and the indication 'adenopathy and/or splenomegaly and/or hepatomegaly' represented 70% of the indications. Overall BMB diagnostic yield was 32.7%, lymphoma being the main histologic finding (31%). Among indications, cytopenia(s) had the highest diagnostic yield (49.1%). Isolated fever of unknown origin had low diagnostic yield (5.6%). Factors independently associated with contributive BMB were: anemia, neutropenia, circulating immature granulocytes or blasts, monoclonal gammopathy, period of BMB processing, quality of BMB, and immunohistochemestry (IHC) analysis. Concomitant BMA improved diagnostic yield by 5.5%, mostly for myelodysplastic syndromes. CONCLUSION: Cytopenia(s), blood cythemias and monoclonal gammopathy are indications with the highest diagnostic yield. Concomitant BMA and IHC analysis should be systematically performed to increase BMB diagnostic yield in internal medicine.

BACKGROUND: Giant cell arteritis (GCA) is frequently associated with aortic involvement that is likely to cause life-threatening structural complications (aneurysm, dissection). Few studies have investigated the occurrence of these complications, and no predictive factor has been identified so far. The aim of this study was to investigate factors associated with the risk of aortic complications in a cohort of GCA aortitis. METHODS: Data of all patients managed with aortitis (CT or 18 FDG PET) at the diagnosis of GCA in five hospitals from May 1998 and April 2019 were retrospectively collected. Clinical features were compared according to the presence of aortitis symptoms. The predictive factors of occurrence or aggravation of aortic structural abnormalities were investigated. RESULTS: One hundred and seventy-one patients with GCA aortitis were included; 55 patients (32%) had symptoms of aortitis (dorsal/lumbar/abdominal pain, aortic insufficiency) at diagnosis. The median follow-up was 38 months. Aortic complications occurred after a median time of 32 months. There were 19 new aortic aneurysms or complications of aneurysm and 5 dissections. Survival without aortic complication was significantly different between the symptomatic and non-symptomatic groups (Log rank, p = 0.0003). In multivariate analysis the presence of aortitis symptoms at diagnosis (HR 6.64 [1.95, 22.6] p = 0.002) and GCA relapse (HR 3.62 [1.2, 10.9] p = 0.02) were factors associated with the occurrence of aortic complications. CONCLUSION: In this study, the presence of aortitis symptoms at the diagnosis of GCA aortitis and GCA relapse were independent predictive factors of occurrence of aortic complications during follow-up.

OBJECTIVE: To investigate differences between childhood (cPAN)- and adult-onset polyarteritis nodosa (aPAN) patients. METHODS: cPAN patients' clinical findings at onset and outcomes were compared to those of aPAN patients from the French Vasculitis Study Group registry matched for year of enrollment and initial systemic versus cutaneous disease. Their information on medications, disease activity and damage were collected. Kaplan-Meier relapse-free survival curves and the log-rank test were used to analyze cPAN versus aPAN differences for predefined outcomes. RESULTS: Twenty-one children with systemic and 13 with cutaneous PAN were compared with 84 systemic- and 27 cutaneous-matched aPAN patients. Median follow-up exceeded 5â¯years for both groups. At study entry, mononeuritis multiplex was less frequent in systemic cPAN than systemic aPAN (Pâ¯=â¯0.04), and purpura and myalgias were less frequent in cutaneous cPAN than cutaneous aPAN (Pâ¯<â¯0.03). During follow-up, systemic cPAN relapsed more often than matched systemic aPAN (Pâ¯<â¯0.0001), while relapse rates were similar for cutaneous disease (Pâ¯>â¯0.05). Mostly minor relapses, predominantly involving the skin, occurred in all 4 groups. At last visit, damage accrual was comparable for cPAN and aPAN patients, but fewer systemic cPAN patients were treatment-free (15% versus 42%; Pâ¯=â¯0.03). Two (6%) cPAN and 8 (7%) aPAN patients died. CONCLUSION: Systemic PAN is equally severe in children and adults and carries a higher risk of relapse. The main cutaneous PAN features seem not to be influenced by age at disease onset.

OBJECTIVE: To estimate the frequency and severity of anal incontinence and vesico-sphincter events, associated factors, and impact on the quality of life of patients with systemic sclerosis. METHODS: Questionnaires assessing anal incontinence (Miller score), vesico-sphincter events (Urogenital Distress Inventory) and quality of life [Short Form Health Survey 36v2 (SF-36), and Hospital Anxiety and Depression Scale] were mailed to 139 patients with systemic sclerosis at the university hospitals of Besançon and Poitiers, France. Clinical data were collected from the medical records to identify risk factors. RESULTS: Among the 121 (87%) responders, severe vesico-sphincter events or severe anal incontinence occurred in 3.4% and 12.4% of cases, respectively. Frequent urination (66.3%) and anal incontinence to gas (50.4%) were the most frequent symptoms. Anal incontinence was associated positively with vesico-sphincter events, unrelated to obstetrical factors. No correlations were seen with age, sex, or systemic sclerosis characteristics. In multivariate analysis, moderate or severe vesico-sphincter events was associated with higher anxiety and depression scores and lower SF-36 scores; the same results were observed for anal incontinence, but did not reach significance. CONCLUSION: Vesico-sphincter events and anal incontinence are common in systemic sclerosis, and sometimes severe, with a potential negative impact in quality of life. These results will be confirmed by a case-control study with dynamic and manometric assessment, and could legitimate a systematic screening to ensure early therapy and multidisciplinary individual management.

Translational research plays a crucial role in bridging the gap between fundamental and clinical research. The importance of integrating research training into medical education has been emphasized. Predictive factors that help to identify the most motivated medical students to perform academic research are unknown. In a cross-sectional study on a representative sample of 315 medical students, residents and attending physicians, using a comprehensive structured questionnaire we assessed motivations and obstacles to perform academic research curricula (ie, research initiation fellowship, Master 1, Research Master 2, and PhD). Independent predictive factors associated with high "motivation score" (top quartile on motivation score ranging from 0 to 10) to enroll in academic research curricula were derived using multivariate logistic regression analysis. Independent predictors of high motivation score for performing Master 1 curriculum were: "considering that the integration of translational research in medical curriculum is essential" (OR, 3.79; 95% CI, 1.49-9.59; Pâ=â0.005) and "knowledge of at least 2 research units within the university" (OR, 3.60; 95% CI, 2.01-6.47; Pâ<â0.0001). Independent predictors of high motivation score for performing Research Master 2 curriculum were: "attending physician" (OR, 4.60; 95% CI, 1.86-11.37; Pâ=â0.001); "considering that the integration of translational research in medical curriculum is essential" (OR, 4.12; 95% CI, 1.51-11.23; Pâ=â0.006); "knowledge of at least 2 research units within the university" (OR, 3.51; 95% CI, 1.91-6.46; Pâ=â0.0001); and "male gender" (OR, 1.82; 95% CI, 1.02-3.25; Pâ=â0.04). Independent predictors of high motivation score for performing PhD curriculum were: "considering that the integration of translational research in medical curriculum is essential" (OR, 5.94; 95% CI, 2.33-15.19; Pâ=â0.0002) and "knowledge of at least 2 research units within the university" (OR, 2.63; 95% CI, 1.46-4.77; Pâ=â0.001). This is the first study that has identified factors determining motivations and barriers to carry out academic research curricula among undergraduate and postgraduate medical students. Improving these 2 areas will certainly have an impact on a better involvement of the next generation of physicians in translational medicine.

OBJECTIVE: Findings from the WEGENT trial and other short-term studies have suggested that azathioprine (AZA) or methotrexate (MTX) could effectively maintain remission of granulomatosis with polyangiitis (Wegener's) (GPA) or microscopic polyangiitis (MPA). This study was undertaken to examine whether differences in rates of relapse or adverse events would appear after discontinuation of these 2 maintenance regimens, when assessed over a longer followup period. METHODS: Long-term outcomes in patients enrolled in the WEGENT trial were analyzed according to their randomized treatment group (AZA or MTX). Parameters at trial entry were evaluated as potential prognostic factors for death, relapse, or damage in multivariate models. RESULTS: Data from 10 years of followup were available for 112 (88.8%) of the 126 original trial participants. The median followup time was 11.9 years (95% confidence interval [95% CI] 11.3-12.5 years). In patients receiving AZA and those receiving MTX, the 10-year overall survival rates were 75.1% (95% CI 64.8-86.9%) and 79.9% (95% CI 70.3-90.8%) (P = 0.56), respectively, and relapse-free survival rates were 26.3% (95% CI 17.3-40.1%) and 33.5% (95% CI 23.5-47.7%) (P = 0.29), respectively. No between-treatment differences were observed with regard to rates of relapse, adverse events, damage, survival without severe side effects, and survival without relapse and severe side effects. In analyses limited to the 97 patients with GPA, no between-treatment differences in survival rates were observed. The 10-year relapse-free survival rate was lower in patients with GPA than in patients with MPA. However, in the multivariate analysis, anti-proteinase 3 antineutrophil cytoplasmic antibody (ANCA) positivity, and not GPA, was retained as being independently associated with the relapse rate. CONCLUSION: The results of this long-term analysis confirm that AZA and MTX are comparable treatment options for maintaining remission of GPA or MPA. Despite achieving good overall survival with these treatments, relapse rates, adverse events, and damage remain matters of concern and further studies are needed to reduce their frequency in these ANCA-associated vasculitides.

OBJECTIVES: The aim of the study was to compare clinical/imaging findings and outcome in patients with idiopathic (isolated aortitis, IA) and with giant cell arteritis (GCA)-related aortitis. METHODS: Patients from 11 French internal medicine departments were retrospectively included. Aortitis was defined by aortic wall thickening >2mm and/or an aortic aneurysm on CT-scan, associated to inflammatory syndrome. Patients with GCA had at least 3 ACR criteria. Aortic events (aneurysm, dissection, aortic surgeries) were reported, and free of aortic events-survival were compared. RESULTS: Among 191 patients with non-infectious aortitis, 73 with GCA and 44 with IA were included. Patients with IA were younger (65 vs 70 years, p=0.003) and comprised more past/current smokers (43 vs 15%, p=0.0007). Aortic aneurisms were more frequent (38% vs 20%, p=0.03), and aortic wall thickening was more pronounced in IA. During follow-up (median=34 months), subsequent development of aortic aneurysm was significantly lower in GCA when compared to IA (p=0.009). GCA patients required significantly less aortic surgery during follow-up than IA patients (p=0.02). Mean age, sex ratio, inflammatory parameters, and free of aortic aneurism survival were equivalent in patients with IA ≥ 60 years when compared to patients with GCA-related aortitis. CONCLUSIONS: IA is more severe than aortitis related to GCA, with higher proportions of aortic aneurism at diagnosis and during follow-up. IA is a heterogeneous disease and its prognosis is worse in younger patients <60 years. Most patients with IA ≥ 60 years share many features with GCA-related aortitis.

OBJECTIVE: Kawasaki disease (KD) is a vasculitis that mostly occurs in young children and rarely in adults. We analyzed the characteristics of adult-onset KD (AKD) in France. METHODS: We collected retrospective and prospective data for patients with a diagnosis of KD occurring after the age of 18 years. Cases were obtained via various French medical networks and identified from the international literature. RESULTS: We included 43 patients of AKD at 26 institution from 1992 to 2015, with mean (SD) age 30 (11) years (range 18-68) and sex ratio (M/F) 1.2; 34 patients met the American Heart Association criteria and 9 were incomplete AKD. The median time to diagnosis was 13 days (interquartile range 8-21). The main symptoms were fever (100%), exanthema (98%), changes in the extremities (91%), conjunctivitis (77%), oral cavity changes (89%), cervical adenitis (55%) and cardiac abnormalities (45%). Overall, 35% of patients showed large-vessel vasculitis: coronary vasculitis (26%) and coronary aneurysm (19%). Treatment was mostly intravenous immunoglobulins (79%) and aspirin (81%). Four patients showed myocardial infarction due to coronary vasculitis, but none were treated with IVIg because of late diagnosis. After a median follow-up of 5 months (range 1-117), persistent aneurysm was noted in 9% of cases. Damage was significantly lower with early treatment than late or no treatment (p=0.01). CONCLUSION: Given the high frequency of cardiac involvement and complications in this series of AKD, diagnosis and treatment should not be delayed, and early IVIg treatment seems to improve the outcome.
