Gastric ulcer and duodenitis associated with coinfection of human herpesvirus-8 and cytomegalovirus in a renal transplant recipient: a case report.

Abstract

BACKGROUND:

The coinfection between cytomegalovirus (CMV) and either human herpesvirus-6 (HHV-6) or HHV-7 in renal transplant recipients is well known; however, there have been few reports of coinfection of CMV associated with HHV-8. This paper presents a first case of acute gastric ulcer and duodenitis associated with CMV and HHV-8 coinfection after renal transplantation.

CASE PRESENTATION:

A 33-year-old male with a history of kidney transplantation was admitted to hospital because of postural epigastric pain. The recipient was CMV seropositive prior to transplantation and received trimethoprim-sulfamethoxazole without universal prophylaxis. Approximately 5 months after renal transplant, the recipient complained postural epigastric pain. An endoscopy revealed diffuse ulcerative lesions in the lower body and in the antrum of the stomach, as well as several erythematous mucosal lesions in the duodenum. Histopathologic examination identified CMV inclusions consistent with invasive CMV disease and immunohistochemical staining showed positive results for HHV-8 and CMV. No tumorous diseases such as Kaposi's sarcoma were detected. After 3 weeks of intravenous ganciclovir treatment, we observed that serum CMV PCR remained within the normal range and clinical symptoms improved. A follow-up endoscopy performed 3 weeks later showed that the severity of the above mentioned lesions had improved.

CONCLUSIONS:

We report the first case of a renal transplant recipient diagnosed with acute gastric ulcer and duodenitis associated with coinfection of CMV and HHV-8. Ganciclovir appears to be effective in diseases associated with coinfection of CMV and HHV-8.
