Reactivation of cytomegalovirus infection (firstreport) associated with drug hypersensitivitysyndrome: case report

A 23-year-old man developed drug hypersensitivitysyndrome associated with reactivation of a cytomegalovirusinfection during treatment with carbamazepine for epilepsy.

The man started receiving carbamazepine 200 mg/day and,15 days later, developed fever and a skin eruption. He stoppedcarbamazepine immediately after he developed the eruption.On admission, he had a reduced general condition with atemperature between 39 and 40°C. He also had erythroderma,facial oedema and painful bilateral inflammatorylymphadenopathy predominately affecting his cervical,inguinal and axillary areas. Laboratory tests revealed anelevated WBC count of 13 000/mm3 with 2000 eosinophils.Histological examination of the eruption revealed keratinocyticnecrosis and superficial dermal oedema with polynucleareosinophils and neutrophils. He was diagnosed with drug-induced hypersensitivity syndrome.

On the second day of hospitalisation, the man startedreceiving corticosteroids 60 mg/day. His fever resolved and hislymphadenopathy and erythroderma abated within 1 week.However, he developed jaundice and right upper abdominalpain. Laboratory tests revealed the following results: ALT4208 IU/L, AST 4500 IU/L, γ-glutamyl transferase 261 IU/L,alkaline phosphatase 525 IU/L and total bilirubin 60 mg/L. Viralhepatitis was suspected, and his corticosteroid dosage wastapered. Serological tests showed signs of cytomegalovirusreactivation in addition to previous infections with Epstein-Barr virus, human hepatitis-6 virus and hepatitis A. Hisjaundice gradually improved and, on the 10th day ofcorticosteroid tapering, his transaminase levels normalised.However, 3 days after his jaundice resolved, he developed amaculopapular exanthema which rapidly progressed to anerythroderma similar to the one he had on admission.Corticosteroid tapering was halted at a dosage of 45 mg/daywhich he continued receiving for 1 month. After his skineruption lost its redness and his laboratory results normalised,the corticosteroid dosage was tapered and he experienced nofurther relapses within 5 months.
