This paper reviews briefly the clinical manifestations, diagnosis, prognosis and treatment of acute hepatitis B virus infection.

We compared a multiplex polymerase chain reaction assay and a shell vial assay for the detection of herpesviruses infection in 13 Cuban patients who had received kidney transplants. Cytomegalovirus and human herpesvirus 6 were detected in these patients.

A technique was applied to detect early fluorescent antigens (DEFA) of cytomegalovirus (CMV) using the E13 monoclonal antibodies in 52 immuno-compromised patients hospitalized in the Nephrology Institute of Havana. Of the 75 urine or blood (buffy coat) samples taken, 15 were found positive to CMV. Using classical diploid human fibroblast isolation technique, 12 CMV strains were isolation of previously detected positive samples by DEFA. In addition, CMV was isolated from one sample reported to be negative by DEFA. A coincidence of 80% was found between both techniques. With the ELISA test, all the sample studied have IgG antibodies to CMV.
