valacyclovir and Heart-Failure

A 97-year-old lady was hospitalized for left leg cellulitis. Comorbidity included hypertension and congestive heart failure. While in hospital, she developed a painless vesicular rash localized to the territory of the left trigeminal nerve (third branch), which evolved to pustules and crusts (Figure 1). A chickenpox-like disseminated eruption of vesicles followed within 4 days, with the same evolution pattern (Figure 2).The diagnosis of disseminated zoster was suspected. A PCR analysis confirmed the presence of varicella-zoster-virus (VZV) in an abdominal vesicle. The patient was treated with oral valacyclovir for 7 days. Clinical examination, laboratory tests (including HIV serology), and a chest radiograph revealed no evidence of underlying immunodeficiency or malignancy.

This study reports the development of lymphocytic myocarditis in a bilateral lung allograft recipient. A 23-year-old woman developed congestive heart failure and severe left ventricular dysfunction 32 months after a bilateral lung allograft for cystic fibrosis. She had taken oral acyclovir for infectious mononucleosis that was diagnosed 11 months previously. Her viral load for Epstein-Barr virus (EBV) increased, and an echocardiogram revealed a left ventricular ejection fraction of 25% and endomyocardial biopsy revealed lymphocytic myocarditis. She received valacyclovir (1 g x 3 times daily) and made a full recovery 6 months later.
