In this randomized trial, patients with vasculitides who were in complete remission after initial induction therapy received either rituximab at intervals or daily azathioprine. More patients had ...sustained remission with rituximab than with azathioprine.
Granulomatosis with polyangiitis (formerly called Wegener’s granulomatosis), microscopic polyangiitis, and renal-limited antineutrophil cytoplasm antibody (ANCA)–associated vasculitides are the main ANCA-associated vasculitis variants.

A staged therapeutic strategy that combines glucocorticoids and cyclophosphamide to induce remission has dramatically improved survival over the past few decades, but with frequent early and late side effects. The results of two trials (RAVE and RITUXVAS) showed that rituximab was not inferior to daily oral or pulse intravenous cyclophosphamide for the induction . . .
Early identification of ultra-risk diffuse large B-cell lymphoma (DLBCL) patients is needed to aid stratification to innovative treatment. Previous studies suggested high baseline total metabolic ...tumor volume (TMTV) negatively impacts survival of DLBCL patients. We analyzed the prognostic impact of TMTV and prognostic indices in DLBCL patients, aged 60 to 80 years, from the phase 3 REMARC study that randomized responding patients to R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) into maintenance lenalidomide or placebo. TMTV was computed on baseline positron emission tomography/computed tomography using the 41% maximum standardized uptake value method; the optimal TMTV cutoff for progression-free (PFS) and overall survival (OS) was determined and confirmed by a training validation method. There were 301 out of 650 evaluable patients, including 192 patients classified as germinal center B-cell–like (GCB)/non-GCB and MYC/BCL2 expressor. Median baseline TMTV was 238 cm3; optimal TMTV cutoff was 220 cm3. Patients with high vs low TMTV showed worse/higher Eastern Cooperative Oncology Group performance status (ECOG PS) ≥2, stage III or IV disease, >1 extranodal site, elevated lactate dehydrogenase, International Prognostic Index (IPI) 3-5, and age-adjusted IPI 2-3. High vs low TMTV significantly impacted PFS and OS, independent of maintenance treatment. Although the GCB/non-GCB profile and MYC expression did not correlate with TMTV/survival, BCL2 >70% impacted PFS and could be stratified by TMTV. Multivariate analysis identified baseline TMTV and ECOG PS as independently associated with PFS and OS. Even in responding patients, after R-CHOP, high baseline TMTV was a strong prognosticator of inferior PFS and OS. Moreover, TMTV combined with ECOG PS may identify an ultra-risk DLBCL population. This trial was registered at www.clinicaltrials.gov as #NCT01122472.
•Early identification of ultra-risk DLBCL patients is needed to aid stratification to alternative treatment approaches.•High baseline TMTV (±ECOG) was a strong prognosticator of inferior PFS and OS in REMARC patients post-R-CHOP, irrespective of maintenance.

Objective
To investigate a new therapeutic strategy, with rapid corticosteroid dose tapering and limited cyclophosphamide (CYC) exposure, for older patients with systemic necrotizing vasculitides ...(SNVs; polyarteritis nodosa PAN, granulomatosis with polyangiitis Wegnener's GPA, microscopic polyangiitis MPA, or eosinophilic GPA Churg‐Strauss EGPA).
Methods
A multicenter, open‐label, randomized controlled trial comprising patients ≥65 years old and newly diagnosed as having SNV was conducted. The experimental treatment consisted of corticosteroids for ∼9 months and a maximum of six 500‐mg fixed‐dose intravenous (IV) CYC pulses, every 2–3 weeks, then maintenance azathioprine or methotrexate. The control treatment included ∼26 months of corticosteroids for all patients, combined with 500 mg/m2 IV CYC pulses, every 2–3 weeks until remission, then maintenance for all patients with GPA or MPA and for those with EGPA or PAN with a Five‐Factors Score (FFS) of ≥1. Randomization used a 1:1 ratio computer‐generated list and was performed centrally with sealed opaque envelopes. The primary outcome measure was ≥1 serious adverse event (SAE) occurring within 3 years of followup. Secondary outcome measures included remission and relapse rates.
Results
Among the 108 patients randomized, 4 were excluded (early consent withdrawal or protocol violation). Mean ± SD age at diagnosis was 75.2 ± 6.3 years. Analysis at 3 years included 53 patients (21 GPA, 21 MPA, 8 EGPA, and 3 PAN) in the experimental arm and 51 patients (15 GPA, 23 MPA, 6 EGPA, and 7 PAN) in the conventional arm. In total, 32 (60%) versus 40 (78%) had ≥1 SAE (P = 0.04), most frequently infections; 6 (11%) versus 7 (14%) failed to achieve remission (P = 0.71); 9 (17%) versus 12 (24%) died (P = 0.41); and 20 (44%) of 45 versus 12 (29%) of 41 survivors in remission experienced a relapse (P = 0.15).
Conclusion
For older SNV patients, an induction regimen limiting corticosteroid exposure and with fixed low‐dose IV CYC pulses reduces SAEs in comparison to conventional therapy, and does not affect the remission rate. Three‐year relapse rates remain high for both arms.
Adult-onset Still disease (AOSD) is a rare systemic inflammatory disorder. A few patients develop organ complications that can be life-threatening. Our objectives were to describe the disease course ...and phenotype of life-threatening AOSD, including response to therapy and long-term outcome.
A multicenter case series of intensive care medicine (ICU) patients with life-threatening AOSD and a systematic literature review.
Twenty patients were included. ICU admission mostly occurred at disease onset (90%). Disease manifestations included fever (100%), sore throat (65%), skin rash (65%), and arthromyalgia (55%). Serum ferritin was markedly high (median: 29,110 ng/mL). Acute respiratory failure, shock and multiple organ failure occurred in 15 (75%), 10 (50%), and 7 (35%) cases, respectively. Hemophagocytosis was demonstrated in eight cases. Two patients died. Treatment delay was significant. All patients received corticosteroids. Response rate was 50%. As second-line, intravenous immunoglobulins were ineffective. Anakinra was highly effective. After ICU discharge, most patients required additional treatment. Literature analysis included 79 cases of AOSD with organ manifestations, which mainly included reactive hemophagocytic syndrome (42%), acute respiratory failure (34%), and cardiac complications (23%). Response rate to corticosteroids was 68%. Response rates to IVIgs, cyclosporin, and anakinra were 50%, 80%, and 100%, respectively.
AOSD should be recognized as a rare cause of sepsis mimic in patients with fever of unknown origin admitted to the ICU. The diagnosis relies on a few simple clinical clues. Early intensive treatment may be discussed. IVIgs should be abandoned. Long-term prognosis is favorable.
Abstract
Objective
In a previous controlled trial, 1-year adjunction of AZA to glucocorticoids (GC) for patients with non-severe, newly diagnosed eosinophilic granulomatosis with polyangiitis (EGPA) ...failed to lower remission failure, vasculitis relapse and isolated asthma/rhinosinus exacerbation rates, or cumulative GC use at month (M) 24. The aim of this study was to analyse longer-term outcomes to determine whether subsequent vasculitis relapse or isolated asthma/rhinosinus exacerbation (IARE) rates differed.
Methods
After M24, patients were followed prospectively, being treated based on physicians’ best judgment. Flares and reasons for increased GC dose or immunosuppressant use were recorded, and reviewed according to randomization group to distinguish vasculitis relapses from IAREs according to EGPA Task Force recommendations.
Results
Fifty EGPA trial participants were followed for a median (interquartile range) of 6.3 (5.4–7.6) years; two (4%) died 11 months post-inclusion. By M24, vasculitis had relapsed in 21/49 (43%) patients and 14/50 (28%) had IAREs. Another patient died 4.8 years post-inclusion (infection). Among nine patients with subsequent vasculitis relapses, three had a major relapse and three had their first relapse after M24; among 25 patients with later IAREs, 17 occurred after M24. At 5 years, respective vasculitis relapse and IARE rates were 48% (95% CI 34.0, 62.6) and 56% (95% CI 41.7, 70.8), with no between-arm differences (P = 0.32 and 0.13). No entry clinical or biological parameter was associated with these outcomes during follow-up.
Conclusion
These results confirmed that 1-year AZA and GC induction obtained good overall survival but no long-term benefit for non-severe EGPA patients. Vasculitis relapses, occurring mostly during the first 2 years, and IAREs, occurring throughout follow-up, require other preventive treatments.

Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare life-threatening thrombotic microangiopathy requiring urgent therapeutic plasma exchange (TPE). However, the exact impact of a ...slight delay in TPE initiation on the subsequent patients' outcome is still controversial.
We aimed to study the frequency, short-term neurological consequences, and determinants of diagnostic delay in iTTP.
We conducted a retrospective monocentric study including patients with a first acute episode of iTTP (2005-2020) classified into 2 groups: delayed (>24h from first hospital visit, group 1) and immediate diagnosis (≤24h, group 2).
Among 42 evaluated patients, 38 were included. Eighteen cases (47%) had a delayed diagnosis (median: 5 days). The main misdiagnosis was immune thrombocytopenia (67%). The mortality rate was 5% (1 death in each group). Neurological events (stroke/TIA, seizure, altered mental status) occurred in 67% vs 30% patients in group 1 and 2, respectively (p = 0.04). Two patients in group 1 exhibited neurological sequelae. The hospital length of stay was longer in group 1 (p = 0.02). At the first hospital evaluation, potential alternative causes of thrombocytopenia were more prevalent in group 1 (33% vs 5%, p = 0.04). Anemia was less frequent in group 1 (67% vs 95%, p = 0.04). All patients had undetectable haptoglobin levels. By contrast, 26% of schistocytes counts were <1%, mostly in group 1 (62% vs 11%, p = 0.01).
Diagnostic delay is highly prevalent in iTTP, with a significant impact on short-term neurological outcome. In patients with profound thrombocytopenia, the thorough search for signs of incipient organ dysfunction, systematic hemolysis workup, and proper interpretation of schistocytes count are the key elements of early diagnosis of TTP.

The aim of the study was to describe the evolution of mortality and cause-specific mortality over time in patients with systemic necrotizing vasculitides (SNV), including polyarteritis nodosa (PAN), ...granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA).
Patients with SNV from the French Vasculitis Study Group registry were divided into 5 groups according to the date of diagnosis: <1980, 1980–1989, 1990–1999, 2000–2010, and ≥ 2010. The causes of death were classified as vasculitis, infection, cardiovascular, malignancy, miscellaneous, or unknown.
Among the 2217 patients included (PAN 16.1%, GPA 41.7%, EGPA 22.6%, MPA 19.6%), overall incidence of death was 2.26 per 100 person-years. The overall survival improved during each period considered. The 5-year survival rate increased from 72.2% (95% confidence interval CI 59.7–87.2) for patients diagnosed before 1980 to 94.5% (95% CI 90.4–98.8) after 2010 (p < 0.001). Periods of diagnosis, age, and male gender were independently associated with a poor survival with a non-significant difference between vasculitis. The incidence of mortality between the 1980s and after 2010 significantly decreased for vasculitis-related (p = 0.03) and cardiovascular-related deaths (p = 0.04). Incidence of death by infection remained stable between the 1980s and the 2000s but no death by infection occurred after 2010. The incidence of death by malignancy remained stable over time.
Overall survival of SNV patients has improved since the 1980s with the decrease of vasculitis- and cardiovascular-related deaths, but cancer-related mortality remained stable. These results highlight malignancy as the current target to improve the overall prognosis.
•Overall survival of SNV patients has dramatically improved since the 1980s.•Vasculitis-related mortality is nowadays rare reflecting the progress in the treatment of SNV.•Side effects of immunosuppressive drugs reflect the current target in SNV.
Triplet-drug regimen bortezomib-thalidomide-dexamethasone (VTD) and bortezomib-lenalidomide-dexamethasone (VRD) are considered as standard of care induction prior autologous stem-cell transplantation ...(ASCT) in myeloma. In addition to improve response rate, induction therapy should preserve an adequate stem-cell collection. In the present retrospective study, we analyzed stem-cell collection in 325 newly diagnosed myeloma patients who received either VTD or VRD induction before ASCT. Stem-cell mobilization consisted of intravenous cyclophosphamide plus G-CSF. Plerixafor was administered preemptively to rescue mobilization. In comparison with VTD, VRD induction was associated with a more frequent use of plerixafor (19.3% versus 5.4%, p = 0.004) and with an increased number of apheresis to reach adequate collection (>2 apheresis required in 42.3% versus 30.2%, p = 0.05). Moreover, more patients experienced collection failure in the VRD group (6% versus 1.8%, p = 0.004). The median number of CD34-positive cells (×10
/kg) was lower in the VRD group: 8.5 versus 9.3 (p = 0.05) in the VTD group. The vast majority of patients underwent ASCT (93% versus 98%, in VRD and VTD group, respectively). These data highlight the need of optimal stem-cell collection strategy, especially in the context of tandem transplantation and incorporation of anti-CD38 monoclonal antibody into induction.
