Necrotizing autoimmune myopathy (NAM) is a group of acquired myopathies characterized by prominent myofiber necrosis with little or no muscle inflammation. Recently, researchers identified autoantibodies (aAb) against 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) in patients with NAM, especially in statin-exposed patients. Here we report what is(More)
OBJECTIVE To analyze the characteristics, outcomes, and predictive factors of disease-modifying antirheumatic drug (DMARD) use in 48 patients with antisynthetase syndrome [characterized by myositis, interstitial lung disease (ILD), arthritis, Raynaud's phenomenon (RP), and/or mechanic's hands] and the presence of anti-histidyl-transfer RNA synthetase(More)
Histiocytoses are a group of heterogeneous diseases that mostly comprise Langerhans cell histiocytosis (LCH) and non-LCH. The association of LCH with non-LCH is exceptional. We report 23 patients with biopsy-proven LCH associated with Erdheim-Chester disease (ECD) (mixed histiocytosis) and discuss the significance of this association. We compare the(More)
OBJECTIVE Erdheim-Chester disease (ECD) is a rare form of non-Langerhans' cell histiocytosis that may present with pulmonary involvement. We undertook the current study to evaluate the characteristic features of pulmonary involvement in ECD, in the largest single-center series of patients reported to date. METHODS We performed a retrospective study of the(More)
Two patients with AIDS developed microscopically verified focal cryptococcal lymphadenitis while treated with highly active anti-retroviral therapy for 8 and 15 months. Both were treated with fluconazole as a secondary prophylaxis for prior cryptococcal meningitis. Cryptococcus neoformans did not grow. Amphotericin was ineffective. Anti-inflammatory drugs(More)
OBJECTIVE To analyze the factors associated with response to anti-tumor necrosis factor (anti-TNF) treatment and compare the efficacy and safety of infliximab (IFX) and adalimumab (ADA) in patients with refractory noninfectious uveitis. METHODS This was a multicenter observational study of 160 patients (39% men and 61% women; median age 31 years(More)
Cancer can occur in patients with inflammatory myopathies. This association is mainly observed in dermatomyositis, and myositis-specific antibodies have allowed us to delineate patients at an increased risk. Malignancy is also reported in patients with necrotizing autoimmune myopathies, but the risk remains elusive. Anti-signal recognition particle or(More)
Up to 50% patients with sarcoidosis display extra-pulmonary disease. However, initial and isolated (ie, without lung disease) acute muscular involvement associated with pseudo-malignant hypercalcemia is very uncommon. We report on 3 cases of life-threatening hypercalcemia revealing florid and isolated acute sarcoid-like myositis.All patients complained of(More)
OBJECTIVE Immunosuppressive therapy may trigger hepatitis B virus (HBV) reactivation for increased morbidity and mortality. We aimed to describe HBV reactivation in patients receiving treatment for immune-mediated inflammatory diseases (IMIDs) and to evaluate a predefined algorithm for its prevention. METHODS Physicians submitted data for patients(More)
