Varicella-zoster Infection in Adults with Cystic Fibrosis: Role of Acyclovir

Abstract

Of 159 adult patients with cystic fibrosis, 5 were documented to have varicella-zoster infection that resulted in an infective pulmonary exacerbation that required intravenous acyclovir and additional antibiotic treatment. Stable serial pulmonary function values were observed over a 1-year period in 4 patients and no complications resulted from treatment. Early treatment with acyclovir in combination with appropriate antibiotics may prevent pulmonary deterioration in adult patients with cystic fibrosis who develop varicella-zoster infection.
