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.
Author comment: Serological tests suggested thepossibility of an interaction between the viral infection andthe drug-induced hypersensitivity syndrome. The score ofintrinsic imputability for carbamazepine causing the drug-induced hypersensitivity was I4 (very likely), and the scores forsymptoms and chronology were S3 and C3, respectively(probable). Systemic corticosteroid therapy may have beenthe reason for viral reactivation.Jamali M, et al. Carbamazepine hypersensitivity syndrome associated withcytomegalovirus reactivation.

» Editorial comment: A search of AdisBase and Medline didnot reveal any previous case reports of cytomegalovirusinfection associated with carbamazepine. The WHO AdverseDrug Reactions database contained one report ofcytomegalovirus virus infection associated with carbamazepine.
