IMPORTANCE: Observational studies have reported that statin use may be associated with improved outcomes of various infections. Ventilator-associated pneumonia (VAP) is the most common infection in the intensive care unit (ICU) and is associated with substantial mortality. OBJECTIVE: To determine whether statin therapy can decrease day-28 mortality in patients with VAP. DESIGN, SETTING, AND PARTICIPANTS: Randomized, placebo-controlled, double-blind, parallelgroup, multicenter trial performed in 26 intensive care units in France from January 2010to March 2013. For power to detect an 8%absolute reduction in the day-28 mortality rate,we planned to enroll 1002 patients requiring invasive mechanical ventilation for more than 2 days and having suspected VAP, defined as a modified Clinical Pulmonary Infection Score of 5 or greater. The futility stopping ruleswere an absolute increase in day-28 mortality of at least 2.7% with simvastatin compared with placebo after enrollment of the first 251 patients. INTERVENTIONS: Participants were randomized to receive simvastatin (60mg) or placebo, started on the same day as antibiotic therapy and given until ICU discharge, death, or day 28, whichever occurred first. MAIN OUTCOMES AND MEASURES: Primary outcomewas day-28 mortality. Day-14, ICU, and hospital mortality rates were determined, as well as duration of mechanical ventilation and Sequential Organ Failure Assessment (SOFA) scores on days 3, 7, and 14. RESULTS: The study was stopped for futility at the first scheduled interim analysis after enrollment of 300 patients, of whom all but 7% in the simvastatin group and 11% in the placebo group were naive to statin therapy at ICU admission. Day-28 mortality was not lower in the simvastatin group (21.2% [95% CI, 15.4% to 28.6%) than in the placebo group (15.2% [95% CI, 10.2% to 22.1%]; P = .10; hazard ratio, 1.45 [95% CI, 0.83 to 2.51]); the between-group difference was 6.0% (95% CI, -3.0% to 14.9%). In statin-naive patients, day-28 mortality was 21.5% (95% CI, 15.4% to 29.1%) with simvastatin and 13.8% (95% CI, 8.8% to 21.0%) with placebo (P = .054) (between-group difference, 7.7% [95% CI, -1.8% to 16.8%). There were no significant differences regarding day-14, ICU, or hospital mortality rates; duration of mechanical ventilation; or changes in SOFA score. CONCLUSIONS AND RELEVANCE: In adults with suspected VAP, adjunctive simvastatin therapy compared with placebo did not improve day-28 survival. These findings do not support the use of statins with the goal of improving VAP outcomes. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01057758.

Rosai-Dorfman disease (RDD) is a rare non-Langerhans histiocytosis that usually presents with lymphadenopathy. Although isolated involvement of the CNS was considered to be uncommon, numerous cases have been reported in recent years. For RDD of the CNS, the treatment consists, in general, of surgery. In cases of partial resection or relapse, chemotherapy regimens, corticosteroids, and/or radiotherapy have yielded negative results. The authors describe the case of a 57-year-old man with a history of chronic Q fever who presented with aphasia and partial seizure. Computed tomography of the brain revealed a left frontotemporal lesion that was suggestive of a meningioma. The lesion was partially resected and histopathological evaluation revealed the presence of RDD. Nineteen months later, a Jacksonian seizure prompted MRI evaluation, which disclosed a local recurrence of the tumor. Computed tomography and FDG-PET demonstrated that the RDD involved no other site, but the presence of ileitis, noted on ileoscopy, led to the diagnosis of Crohn disease. Treatment with the purine analog azathioprine was initiated, leading to an objective and sustained response in both the RDD tumor and ileitis over 35 months of follow-up. This case report highlights the potential use of a purine analog in cases of relapsing RDD of the CNS and a possible common defect of macrophage regulation in RDD, Crohn disease, and Q fever.

Tracheobronchial stenosis (TBS) is noted in 12-23% of patients with granulomatosis with polyangiitis (GPA), and includes subglottic stenosis and bronchial stenosis. We aimed to analyse the endoscopic management of TBS in GPA and to identify factors associated with the efficacy of endoscopic interventions.We conducted a French nationwide retrospective study that included 47 patients with GPA-related TBS.Compared with patients without TBS, those with TBS were younger, more frequently female and had less frequent kidney, ocular and gastrointestinal involvement and mononeuritis multiplex. Endoscopic procedures included 137 tracheal and 50 bronchial interventions, mainly endoscopic dilatation, local steroid injection and conservative laser surgery, and less frequently stenting. After the first endoscopic procedure, the cumulative incidence of endoscopic treatment failure was 49% at 1 year, 70% at 2 years and 80% at 5 years. Factors significantly associated with a higher cumulative incidence of treatment failure were a shorter time from GPA diagnosis to endoscopic procedure [hazard ratio (HR) 1.08 (95% CI 1.01, 1.14); P = 0.01] and a bronchial stenosis [HR 1.96 (95% CI 1.28, 3.00); P = 0.002]. A prednisone dose 30 mg/day at the time of the procedure was associated with a lower cumulative incidence of treatment failure [HR 0.53 (95% CI 0.31, 0.89); P = 0.02].TBS represents severe and refractory manifestations with a high rate of restenosis. High-dose systemic CSs at the time of the procedure and increased time from GPA diagnosis to bronchoscopic intervention are associated with a better event-free survival. In contrast, bronchial stenoses are associated with a higher rate of restenosis than subglottic stenosis.

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is a treatment option for relapsed anaplastic large cell lymphoma (ALCL) in children, but reports on its efficacy in this disease are still limited. We analyzed data concerning 34 patients under 18 years of age prospectively registered in the French SFGM-TC database, who had undergone an allo-SCT for the treatment of ALK+ ALCL between 1993 and 2011. At transplant, 28 patients (82.4%) were in CR, whereas 6 exhibited detectable disease. Conditioning regimens were mostly myelo-ablative (n=31). With a median follow-up of 6 years, 5-year overall and event-free survival rates were 70% (SE=8%) and 58% (SE=9%), respectively. The 5-year cumulative incidence of relapse and treatment-related mortality was 18% (SE=7%) and 24% (SE=8%), respectively. Six patients had relapsed (median time, 141 days (35-235)). A durable CR had been obtained in 4/6 patients after injection of donor lymphocytes (n=1) or vinblastine-corticosteroid therapy (n=3). Ten patients had died, eight due to transplant toxicity and two due to progressive disease. Allo-SCT is an efficient treatment for pediatric patients with high-risk relapsed ALK+ ALCL. However, the overall morbidity of allo-SCT raises questions about its place, given the efficacy of targeted agents currently under development in this disease.

To study the effect of age on the risk-benefit balance of abatacept in RA.Data from the French orencia and RA registry, including a 2-year follow-up, were used to compare the effectiveness and safety of abatacept according to age.Among the 1017 patients, 103 were very elderly (75 years), 215 elderly (65-74), 406 intermediate aged (50-64) and 293 very young (<50). At baseline, elderly and very elderly patients had longer disease duration, higher CRP levels and higher disease activity. These age groups showed a lower incidence of previous anti-TNF therapy and less common concomitant use of DMARDs, but a similar use of corticosteroid therapy. After adjusting for disease duration, RF/ACPA positivity, use of DMARDs or corticosteroids and previous anti-TNF treatment, the EULAR response (good or moderate) and the remission rate were not significantly different between the four age groups. At 6 months, the very elderly had a significantly lower likelihood of a good response than the very young (odds ratio = 0.15, 95% CI: 0.03, 0.68). The decrease in DAS28-ESR over the 24-month follow-up period did not differ by age. Increasing age was associated with a higher rate of discontinuation for adverse events, especially severe infections (per 100 patient-years: 1.73 in very young, 4.65 in intermediates, 5.90 in elderly, 10.38 in very elderly; P < 0.001).The effectiveness of abatacept is not affected by age, but the increased rate of side effects, especially infections, in the elderly must be taken into account.

The use of plasma exchanges (PLEX) in systemic necrotizing vasculitides (SNV) still need to be codified. To describe indications, efficacy and safety of PLEX for the treatment of SNV, we conducted a multicenter retrospective study on patients with ANCA-associated vasculitis (AAV) or non-viral polyarteritis nodosa (PAN) treated with PLEX. One hundred and fifty-two patients were included: GPA (n = 87), MPA (n = 56), EGPA (n = 4) and PAN (n = 5). PLEX were used for rapidly progressive glomerulonephritis (RPGN) in 126 cases (86%), alveolar hemorrhage in 64 cases (42%), and severe mononeuritis multiplex in 23 cases (15%). In patients with RPGN, there was a significant improvement in renal function compared to baseline value (P < 0.0001), the plateau being reached at month 3 after PLEX initiation, and estimated glomerular filtration rate improved especially as the number of PLEX increased. In patients with alveolar hemorrhage, mechanical ventilation was discontinued in all patients after a median time of 15 days. Patients treated for mononeuritis multiplex showed improvement of severe motor weakness. After a median follow of 22 months, 18 deaths (12%) were recorded, mainly in patients with RPGN and within the first 6 months. Incidence of end-stage renal disease and/or death was similar between groups of different baseline renal function, but was increased in MPO-ANCA compared to PR3-ANCA. Adverse events attributable to PLEX were recorded in 63%. No death occurred during PLEX. This large series describes indications, efficacy and safety of PLEX in daily practice. Randomized controlled studies are ongoing to define optimal indications, PLEX regimen and concomitant medications.

Haploidentical allogeneic stem cell transplantation (CST) has globally taken off in the past decade. It appears to be a valid alternative to other sources of stem cells; however, further research is necessary to validate the use of this approach in standard patient care. In the attempt to harmonize clinical practices between different French transplantation centers, the French Society of Bone Marrow Transplantation and Cell Therapies (SFGM-TC) set up its fourth annual series of workshops which brought together practitioners from all of its member centers. These workshops took place in September 2013 in Lille. This is part two of the recommendations regarding allogeneic stem cell transplantation from an HLA-haploidentical related donor.

In the attempt to harmonize clinical practices between different French transplantation centers, the French Society of Bone Marrow Transplantation and Cell Therapy (SFGM-TC) set up the fourth annual series of workshops which brought together practitioners from all member centers and took place in September2013 in Lille. Here, we report our recommendations regarding the use of donor lymphocyte injection (DLI) in the prophylactic, pre-emptive and curative settings. This work has been limited to allogeneic stem cell transplantations from an HLA-matched (10/10) or -one antigen-mismatched (9/10) donor.
