A prospective study of cytomegalovirus (CMV) infections has been carried out in 28 renal graft recipients. The protocol called for frequent blood and urine sampling during the first year after transplantation, but death or graft loss caused earlier termination in nearly half the patients. In this material 5/7 (71%) susceptible patients developed primary infections and 20/21 experienced a secondary infection (95%). Viruria was detected in 79% and viremia in 43%. The type of blood cell responsible for the viremic phase was studied by separating the blood cells on a density gradient. The polymorphonuclear cell fraction was the most common source of virus but virus could also be recovered from the mononuclear cell fraction. As some samples that were freeze-thawed repeatedly never yielded virus, it would appear that viable cells are needed for virus isolation. In both primary and secondary infections isolation of CMV from blood cells often preceded the isolation of CMV from urine. Among variables tested for a possible relationship to the occurrence of CMV viremia the only one to display such an association was the time at which rejection episodes occurred. In 19/28 such episodes recorded in 19 patients there was a temporal relationship to viremia (p less than 0.03). Seven of the patients experienced clinical symptoms suggestive of CMV infection as fever, cough, myalgia, arthralgia, chest pain and pneumonia. Laboratory signs included elevated amino acid transferase levels, leukopenia and thrombocytopenia and a specific anti-CMV antibody response.

We reviewed the thirty cases of cytomegalovirus infections with occurred in previously healthy patients, hospitalised for fever from 1981 to 1992. Pregnant women, transplant recipients, HIV infected persons and all immunocompromised subjects were excluded. We observed 34 cases (18 women, 16 men) whose mean age was 34 years (17 to 79). Fever appeared progressively (73%), persisted more than 15 days (87%) and was well tolerated. The main functional symptoms were headaches, myalgia (53%), profuse sweat (50%), abdominal pain, diarrhea, recent loss of weight, dry cough (51%). Splenomegaly was present in 24% of the cases. Chest X ray was always normal. Differential blood count was always inverse and an authentic mononucleosis syndrome was present in 91%: it appeared mainly 13 days after onset of symptoms. Hepatic abnormalities were nearly constant, especially cytolytic (97%) (transaminases three or four times upper the normal limit) but also cholestatic (62%). Thrombopenia has been noticed once (48,000/mm3). Serological diagnosis was confirmed with Elisa test (anti CMV Ig M: 30 cases) or complement fixation test (seroconversion: one, significant increase of the titers: two). CMV viremia, studied in seven patients, was positive in three. Spontaneous or treated (NSAI in 30%) outcome was nearly always favourable (97%). Two patients presented severe complications: meningo encephalitis and spleen rupture. CMV infection in previously healthy patients has to be suspected, without waiting for the mononucleosis syndrome, in view of a prolonged, well tolerated febrile illness, without pharyngitis, associated with hyperlymphocytosis and mild cytolysis. A careful follow-up is needed to detect the rare but severe complications.
