Cytomegalovirus mononucleosis in a healthy adult: association with hepatitis, secondary Epstein-Barr Virus antibody response and immunosuppression

Abstract

A 35 year old previously healthy physician had clinical manifestations of a mononucleosis illness complicated by arthralgia, vesicular pharyngitis and hepatitis. Initially, the patient had cytomegalovirus (CMV) viremia (predominantly in polymorphonuclear leukocytes) followed by the presence of CMV in the urine, throat and semen. He also had an antibody response to the Epstein-Barr virus which appeared to be a secondary type. During the acute phase of illness, only 7 per cent of the patient's lymphocytes formed spontaneous T cell rosettes as compared to a normal value of 65 to 70 per cent. Concurrently, evidence of abnormal delayed hypersensitivity was manifested by the loss of reactivity to mumps skin test antigen. All clinical and laboratory abnormalities except for the persistence of CMV in the pharynx, urine and semen returned to normal after resolution of the clinical illness.
