PURPOSE: Cytomegalovirus (CMV) infection in non-immunocompromised adults can sometimes induce hematological and immunological disorders that may mislead diagnosis. METHODS: Case reports of hospitalized non-immunocompromised adults with positive serology for CMV including the presence of immunoglobulin M or seroconversion were assessed in a retrospective study (1981-1998). We focused on clinical and biological abnormalities showing the role of CMV in disruption of functioning of hematological and immunological systems. RESULTS: Among 115 patients, lymphoma-like syndrome with large adenopathies and/or splenomegaly was diagnosed in eight patients, uncovering underlying CMV infection. Lymphoma was accompanied by hematoma in two patients. Three patients presented leg purpura (with thrombotic thrombocytopenic purpura in one case), one patient had cutaneous vasculitis and on other a Still's disease. Blood abnormalities were mononucleosis (64%), anemia (20%), and thrombopenia (25%) often of peripheral or hemolytic origin or due to hypersplenia. Electrophoresis of serum proteins showed an increase in immune globulins in 56% of the cases and monoclonal abnormality in nine cases. Immunological assessment was conducted in 18 patients. At least one abnormality was depicted in ten patients, consisting of either antinuclear, anti-platelet or anti smooth muscle antibodies, cryoglobulinemia, rheumatoid factor, or reduced complement fixation. CONCLUSION: Testing for CMV infection can be of value in case of blood or immunological disorders associated with clinical or biological signs. Although hematological disorders occur early, they are rarely severe. Immunological disorders are rarely symptomatic, but often raise issues regarding the potential genesis of immune diseases in at-risk patients.
