Fatal Chickenpox in a Patient With Nephrotic Syndrome

BACKGROUND: We report our experience with two patients with adult onset of chickenpox in the setting of longstanding steroid therapy for nephrotic syndrome. Ours is a 430-bed tertiary care teaching hospital, The Wellesley Hospital, Toronto, Ontario. Both patients presented as self-referrals to the emergency department. METHODS: The clinical suspicion of chickenpox was rapidly confirmed in both cases by a Tzanck smear preparation, by viral cultures of the vesicle, serology, and skin biopsy. In both patients therapy with high dose acyclovir, 10 mg/kg q8h, intravenously, was instituted based on clinical presentation. RESULTS: Delay in clinical recognition and treatment in our first case resulted in death due to multiorgan failure (MOF). Improved awareness and rapid treatment of the second patient had a favorable outcome with no sequelae. CONCLUSIONS: Chickenpox is not only a childhood illness. Although rare in the adult population, it is associated even in the nonimmunocompromised host with increased morbidity and mortality. Steroid therapy predisposes to early dissemination and a potentially fatal outcome. Adults with immunosuppression should receive prompt systemic treatment with acyclovir.
