Severe drug rash with eosinophilia and systemic symptoms after treatment with minocycline

Introduction Lung involvement is rarely observed in the DRESS syndrome (Drug rash with eosinophilia and systemic symptoms). We report here a severe minocycline induced hypersensitivity syndrome with initial respiratory distress. Case report A 19 year old man was admitted to the intensive care unit for acute respiratory distress with fever (40 degrees C), lymph node enlargement, hepatomegaly, splenomegaly and eosmophilia (1640/mm(3)). Bilateral alveolar opacities were observed on the chest x-ray. Sedation and mechanical ventilation rapidly became necessary because of severe hypoxaemia (47 mm Hg) and the sudden onset of severe aggressive behaviour. The diagnosis of DRESS was immediately suspected as the patient had been treated for acne with minocycline for 28 days, and IV corticosteroids (2 mmg/kg/day) were initiated. Skin lesions were delayed and appeared 3 days later. The outcome was uncertain for the following 6 weeks with serious disturbance of hepatic and renal function. Serology for human herpes virus (HHV6) was' I initially negative but became positive. One year later, after progressive withdrawal of corticosteroid therapy, the patient had made a complete recovery with no sequelae. Conclusion The DRESS syndrome can cause considerable morbidity with multiple, severe visceral functional disturbances. Respiratory physicians should be aware of this syndrome as lung involvement can be serious and may precede cutaneous symptoms.
