Adrenal insufficiency associated with cytomegalovirus infection in two infants

Adrenal insufficiency associated with cytomegalovirus (CMV) is a well-described condition in adults with AIDS, however there is little information about CMV-associated adrenal insufficiency in childhood. The cases of two infants with negative HIV serology, presenting with CMV-associated adrenal insufficiency, are described. Clinical findings and therapeutic interventions are discussed with reference to the affinity of CMV infection for the adrenal gland. The differential diagnosis of adrenal insufficiency in newborns and infants should include CMV infection, and clinical suspicion of CMV-associated adrenal insufficiency should lead to early initiation of appropriate adrenal substitution therapy and ganciclovir antiviral therapy. Timely therapy for CMV-associated adrenal insufficiency can be lifesaving.
