Unexpected death in an infant with AIDS: disseminated cytomegalovirus infection with pancarditis.

Cardiac involvement in patients with acquired immunodeficiency syndrome (AIDS) is being reported with increasing frequency, although the factors responsible for the cardiac abnormalities are rarely identified. We report a case of sudden and unexpected death of an infant with AIDS in whom histologic and virologic studies documented generalized infection with cytomegalovirus (CMV), including pancarditis, sialitis, nephritis, colitis, hepatitis, prostatitis, orchitis, myositis, pneumonitis, and meningoencephalitis. CMV was isolated from four of five tissues cultured. Lymphocytic infiltration in the region of the sinoatrial node could have been responsible for the development of a fatal cardiac arrhythmia, and the autopsy failed to reveal any other cause of death in this infant. Children infected with the human immunodeficiency virus (HIV) need to be closely monitored for cardiac complications bearing in mind that opportunistic infections in AIDS patients may cause cardiac involvement that is atypical or that is overshadowed by the primary manifestations of the infection.
