Secondary hemophagocytic lymphohistiocytosis possibly induced by interferon beta-1a therapy.

A 57-year old woman with a history of multiple sclerosis, treated with interferon beta-1a in the last 5 months, was referred for hyperpyrexia (>40°C) that persisted for 15 days. At admission, there was elevation of transaminases, anemia (hemoglobin 8.9 g/dL), thrombocytopenia (platelet 135,000/mm3), and hypofibrinogenemia (fibrinogen 1.26 g/L). C-reactive protein was 10.7 mg/dL, lactate dehy...

Measles and Secondary Hemophagocytic Lymphohistiocytosis

To the Editor: We found interesting the article by Lupo et al. about a case of fatal measles in an immunocompetent 29-yearold woman (Fatal measles without rash in immunocompetent adult, France; http://dx.doi.org/10.3201/ eid1803.111300). Perhaps, however, the possible diagnosis of secondary hemophagocytic lymphohistiocytosis (HLH) should also have been considered in that setting. HLH is a poten...

Interferon beta-1a–induced morphea

IL-4: Interleukin 4 IFN-b: Interferon beta IFN-b1a: Interferon beta-1a MS: Multiple sclerosis SSc: Systemic sclerosis Th2: T helper 2 INTRODUCTION Interferon beta-1a (IFN-b1a) is a cytokine therapy used in the treatment of relapsing-remitting multiple sclerosis. The most common adverse injection site reactions include local erythema, pain, and induration. Other less frequently encountered react...

Beta-Blocker Therapy and Hemophagocytic Lymphohistiocytosis: A Case Report

Objective. The aim of this paper is to describe a fatal case of hemophagocytic lymphohistiocytosis (HLH) in a patient with severe heart failure, who was treated with low-dose propranolol. Patient and Interventions. We report on a 7-month-old boy with Downs syndrome who was born with an unbalanced, left dominant atrioventricular septal defect and aortic coarctation. Despite coarctation repair an...
