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
Data regarding the safety of co-administration of ibrutinib with anticoagulants in real-life settings are scarce. Using a nationwide database, we conducted a nested case-control study in a cohort of new users of ibrutinib to assess the risk of clinically relevant bleeding (CRB) associated with anticoagulation. Cases were patients with a diagnosis of CRB, defined as hospitalization with a diagnosis of bleeding. The date of CRB constituted the index date. Up to four controls were matched on sex, age at index date and duration of follow-up. The risk of CRB associated with anticoagulation in patients receiving ibrutinib was estimated using conditional logistic regression models, providing odds ratios (OR) adjusted for risk factors of bleeding. Among 614 cases and 2407 matched controls, the risk of CRB was significantly higher in patients receiving both ibrutinib and anticoagulants (adjusted OR [aOR] 2.54, confidence interval [CI] 95% [1.94; 3.32]). When considering anticoagulant class, aOR was 1.99 (CI 95% [1.19; 3.33]) for VKA, 2.48 (CI 95% [1.76; 3.47]) for direct oral anticoagulants and 3.40 (CI 95% [2.01; 5.75]) for parenteral anticoagulants. In conclusion, this study found a 2.5-fold increased risk of CRB in patients receiving both ibrutinib and anticoagulants in real-life settings, and similar aOR among oral anticoagulants.

BACKGROUND: The landscape of polyarteritis nodosa (PAN) has substantially changed during the last decades. Recent data regarding causes, characteristics, and prognosis of systemic PAN in the modern era are lacking. METHODS: This retrospective study included patients with systemic PAN referred to the French Vasculitis Study Group between 2005 and 2019. Characteristics, associated conditions and outcomes were collected, and predictors of relapse and death were analyzed. RESULTS: 196 patients were included. Main clinical symptoms were constitutional (84%), neurological (59%), skin (58%) and musculoskeletal (58%) manifestations. Secondary PAN accounted for 55 (28%) patients, including myelodysplastic syndrome (9%), solid cancer (7%), lymphoma (4%) and autoinflammatory diseases (4%). No patient had active HBV infection. All treated patients (98.5%) received glucocorticoids (GCs), alone (41%) or in combination with immunosuppressants (59%), with remission achieved in 90%. Relapses were independently associated with age >65 years (HR 1.85; 95% CI1.12-3.08), gastrointestinal involvement (1.95; 95% CI1.09-3.52) and skin necrotic lesions (HR 1.95; 95%CI 1.24-3.05). One-, 5- and 10-year overall survival rates were 93%, 87% and 81%, respectively. In multivariate analyses, age >65 years (HR 2.80; 95%CI 1.23-6.37), necrotic purpura (HR 4.16; 95%CI 1.62-10.70), acute kidney injury (HR 4.89; 95% 1.71-13.99) and secondary PAN (HR 2.98; 95%CI 1.29-6.85) were independently associated with mortality. CONCLUSION: Landscape of PAN has changed during the last decades, with the disappearance of HBV-PAN and the emergence of secondary PAN. Relapse rate remains high, especially in aged patients with gastrointestinal and cutaneous necrosis, as well as mortality.

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.

OBJECTIVES: GCA is a large vessel vasculitis for which triggering factors remain unknown. Clonal haematopoiesis (CH) was associated with atherosclerosis through the induction of inflammation in myeloid cells, and data suggest that CH expansion and inflammation may support each other to induce a pro-inflammatory loop. Our objective was to describe the impact of JAK2p.V617F-mutated myeloproliferative neoplasms (MPNs) on GCA and to screen MPN-free patients for CH mutations. METHODS: We performed a retrospective case-control study comparing the characteristics of 21 GCA patients with MPN and 42 age- and gender-matched GCA patients without MPN. Also, 18 GCA patients were screened for CH through next-generation sequencing (NGS). RESULTS: The most frequent associated MPN was essential thrombocythaemia (ET; n = 11). Compared with controls, GCA patients with MPN had less-frequent cephalic symptoms (71.4 vs 97.6%; P = 0.004) and higher platelet counts at baseline [485 × 109/l (interquartile range 346-586) vs 346 (296-418); P = 0.02]. There was no difference between groups for other clinical features. Overall survival was significantly shorter in patients with MPN compared with controls [hazard ratio 8.2 (95% CI 1.2, 56.6); P = 0.03]. Finally, screening for CH using NGS in 15 GCA patients without MPN revealed CH in 33%. CONCLUSION: GCA patients with MPN display higher platelet counts and shorter overall survival than controls. This association is not fortuitous, given the possible pathophysiological relationship between the two diseases. CH was found in one-third of GCA patients, which may be higher than the expected prevalence for a similar age, and should be confirmed in a larger cohort.

BACKGROUND: Palliative biliary drainage in patients with unresectable malignant biliary obstruction (MBO) frequently leads to biliary stent infection (BI), which could impact medical care. The aim of this study was to assess the risk factors for BI occurrence in patients after stenting procedure and the impact of BI on patient survival. METHODS: All consecutive patients hospitalized from 2014 to 2018 for MBO and biliary stenting were retrospectively included. Demographic, clinical, and microbiological characteristics of each BI episode during a 1-year follow-up were described. Documented BI was defined as the association of BI episode and confirmed blood stream infection (BSI). Univariate and multivariate analyses were performed to evaluate risk factors for the first BI occurrence. RESULTS: Among 180 patients, 56% were men (mean age of 69±12), and 54% have pancreatic cancer, 16% biliary cancer, 2% hepatic cancer, and 28% lymph node or metastatic compression; metallic stent was placed in 92%. A total of 113 BI episodes occurred in 74 patients, 55% of the first episodes occurring within 3 months after stenting. BI was documented in 56% of the episodes. Enterobacteriaceae were the most frequent pathogens found, while no yeasts were documented. Mortality rate in patients with BI was 64%. Multivariate analysis showed a significant difference in BI occurrence for two criteria: WHO score 3-4 (OR=8.79 [1.79-42.89]; p=0.007) and transpapillary stenting location (OR=3.72 [1.33-10.44]; p=0.013). CONCLUSION: Since transpapillary stenting is a risk factor for BI, preserving the papilla as much as possible is a priority so as to avoid BI.

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.

BACKGROUND: Scedosporium species and Lomentospora prolificans (S/L) are the second most common causes of invasive mold infections following Aspergillus in lung transplant recipients. METHODS: We assessed the current practices on management of S/L colonization/infection of the lower respiratory tract before and after lung transplantation in a large number of lung transplant centers through an international practice survey from October 2016 to March 2017. RESULTS: A total of 51 respondents from 45 lung transplant centers (17 countries, 4 continents) answered the survey (response rate 58%). S/L colonization was estimated to be detected in candidates by 48% of centers. Only 18% of the centers used a specific medium to detect S/L colonization. Scedosporium spp. colonization was a contraindication to transplantation in 10% of centers whereas L prolificans was a contraindication in 31%; 22% of centers declared having had 1-5 recipients infected with S/L in the past 5 years. CONCLUSIONS: This survey gives an overview of the current practices regarding S/L colonization and infection in lung transplant centers worldwide and underscores the need of S/L culture procedure standardization before implementing prospective studies.

The Intergroupe Francophone du Myélome conducted a randomized trial to compare bortezomib-thalidomide-dexamethasone (VTD) with bortezomib-cyclophosphamide-dexamethasone (VCD) as induction before high-dose therapy and autologous stem cell transplantation (ASCT) in patients with newly diagnosed multiple myeloma. Overall, a total of 340 patients were centrally randomly assigned to receive VTD or VCD. After 4 cycles, on an intent-to-treat basis, 66.3% of the patients in the VTD arm achieved at least a very good partial response (primary end point) vs 56.2% in the VCD arm (P = .05). In addition, the overall response rate was significantly higher in the VTD arm (92.3% vs 83.4% in the VCD arm; P = .01). Hematologic toxicity was higher in the VCD arm, with significantly increased rates of grade 3 and 4 anemia, thrombocytopenia, and neutropenia. On the other hand, the rate of peripheral neuropathy (PN) was significantly higher in the VTD arm. With the exception of hematologic adverse events and PN, other grade 3 or 4 toxicities were rare, with no significant differences between the VTD and VCD arms. Our data support the preferential use of VTD rather than VCD in preparation for ASCT. This trial was registered at www.clinicaltrials.gov as #NCT01564537 and at EudraCT as #2013-003174-27.

Age is a well-known factor in solid tumours linked to lower adherence to guidelines. Scarce data exist for haematologic malignancies such as multiple myeloma (MM). The aim of the study was to investigate the relationships among age, adherence to guidelines in MM, and overall survival (OS).The Poitou-Charentes cancer registry has exhaustively registered incident cases of MM from 2008 to 2010. Diagnosis, staging, prognosis, and first-line treatment were compared to the international guidelines. Three hundred and sixty-seven patients aged 36 to 93 years were included. Compliance to diagnostic procedure was 98%, staging 62%, prognosis 30%, and first-line treatment 89%. Cytogenetic analysis was compliant in 37%. Younger age was the strongest factor associated with compliant provision of care (odds ratio 14.4 [6.1-33.8] for <66 years and 2.3 [0.9-6.1] for 66-74 years; P < .0001). The second independent factor was active versus smouldering myeloma (odds ratio 3.5 [1.6-7.3]; P = .0009). Adherence to guidelines is related with OS in multivariate analysis hazard ratio: 1.6 [1.0-2.5]; P = .03. Age is linked with inadequate provision of care in myeloma, particularly prognosis and first-line treatment. Compliance to guidelines seems to be related to OS taking into account the main prognostic factors. Future guidelines should stress the point that age and frailty need to be taken into account in myeloma care.

BACKGROUND: The presence of Janus Kinase 2 (JAK2) V617F mutation represents a major diagnostic criterion for detecting myeloproliferative neoplasms (MPN) and even in the absence of overt MPN, JAK2 V617F mutation is associated with splanchnic vein thrombosis. However, the actual prevalence and diagnostic value of the JAK2 V617F mutation in patients with cerebral venous thrombosis (CVT) are not known. The aims of this study were to assess the prevalence of JAK2 V617F mutation in a large group of consecutive CVT patients, to detect clinical, biological, and radiological features associated with the mutation, and to determine the long-term venous thrombosis recurrence rate in CVT patients with JAK2 mutation but without overt MPN in order to recommend the best preventive treatment. METHODS: This was a prospective study conducted on consecutive patients with a first-ever radiologically confirmed CVT. JAK2 V617F mutation analysis was assessed in all the study subjects. JAK2 V617F-positive patients were followed up to detect new venous thrombotic events. RESULTS: Of the 125 included subjects, 7 were found to have JAK2 V617F mutation (5.6%; 95% CI 2.3-11.2). Older age (p = 0.039) and higher platelet count (p = 0.004) were independently associated with JAK2 V617F positivity in patients without overt MPN. During a mean follow-up period of 59 (SD 46) months, 2 JAK2 V617F-positive patients presented with 4 new venous thromboembolic events. CONCLUSIONS: Screening for the JAK2 V617F mutation in CVT patients seems to be useful even in the absence of overt MPN and/or in the presence of other risk factors for CVT because of its relatively high prevalence and the risk of thrombosis recurrence.

INTRODUCTION: To assess frequency and methods of PID (primary immune deficiency) screening among patients with bronchiectasis by pneumologists in clinical practice. METHODS: All the patients hospitalized in the department of pneumology of the Poitiers University Hospital between April 2013 and April 2020 with a diagnosis of bronchiectasis on chest computerized tomography were included. Patients aged 70 and over and those with already known PID were excluded. Primary endpoint was the proportion of patients having had serum immunoglobulin (Ig) assay and serum protein electrophoresis (SPE) analysis. Secondary endpoints were factors associated with prescription of SPE and/or Ig assay, proportion of patients with newly diagnosed PID and their characteristics and factors associated with repeated courses of antibiotics. RESULTS: Among the 133 patients included, 43% had SPE+Ig assay, 34% SPE only and 23% neither. The proportion of patients with asthma was higher in the "SPE+Ig assay" group (33.3%) compared to the "SPE only" (11.1%) and the "Neither SPE nor Ig assay" groups (6.4%) (P=0.002). Four patients were newly diagnosed for PID of whom 3 had subclass IgG deficiency. Factors associated with repeated courses of antibiotics were generalized bronchiectasis (P=0.02) and asthma (P=0.04). CONCLUSION: PID is underscreened by pneumologists among patients with bronchiectasis. Association of SPE+Ig assay+IgG subclass assay appears as the most accurate combination.

BACKGROUND: Immune checkpoint inhibitors (ICI) have transformed cancer treatment over the last decade. Alongside this therapeutic improvement, a new variety of side effects has emerged, called immune-related adverse events (irAEs), potentially affecting any organ. Among these irAEs, myocarditis is rare but life-threatening. METHODS: We conducted a multicenter cross-sectional retrospective study with the aim of better characterizing ICI-related myocarditis. Myocarditis diagnosis was based on the recent consensus statement of the International Cardio-Oncology Society. RESULTS: Twenty-nine patients were identified, from six different referral centers. Most patients (55%) were treated using anti-programmed-death 1, rather than ICI combination (35%) or anti-programmed-death-ligand 1 (10%). Transthoracic echocardiography was abnormal in 52% of them, and cardiac magnetic resonance showed abnormal features in 14/24 patients (58%). Eleven patients (38%) were classified as severe. Compared with other patients, they had more frequently pre-existing systemic autoimmune disease (45% vs 6%, p=0.018), higher troponin level on admission (42-fold the upper limit vs 3.55-fold, p=0.001), and exhibited anti-acetylcholine receptor autoantibodies (p=0.001). Seven patients (24%) had myocarditis-related death, and eight more patients died from cancer progression during follow-up. Twenty-eight patients received glucocorticoids, 10 underwent plasma exchanges, 8 received intravenous immunoglobulins, and 5 other immunosuppressants. ICI rechallenge was performed in six patients, with only one myocarditis relapse. DISCUSSION: The management of ICI-related myocarditis may be challenging and requires a multidisciplinary approach. Prognostic features are herein described and may help to allow ICI rechallenge for some patients with smoldering presentation, after an accurate evaluation of benefit-risk balance.

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.
