Abstract

Objective: To investigate the incidence and clinical features in patients with cytomegalovirus (CMV)-positive antigenemia during high dose corticosteroid therapy for collagen vascular diseases, and risk factors associated with it. Patients and methods: We examined retrospectively 35 consecutive patients for the presence of CMV-positive pp65 antigenemia. The patients were admitted to Saka General Hospital from 2000 to 2003, and were administered more than 0.5 mg/kg of body weight/day of peroral prednisolone for collagen vascular diseases. Characteristics of patients with and without CMV-positive antigenemia were compared. Results: CMV-positive antigenemia was detected in 14 patients (40.0%), including six with microscopic polyangitis, three with rheumatoid arthritis, and five with other conditions. Three patients (8.6%) were diagnosed as having a CMV disease: pneumonitis or encephalitis. Symptoms and laboratory findings, including slight fever and a low increase in levels of hepatic enzymes and cytopenia, were observed in 10 of the 14 patients. Two patients died of CMV diseases refractory to ganciclovir. Ages of more than 70 years old were associated with the presence of CMV-positive antigenemia (relative risk = 4.5, 95% confidence interval = 1.14-17.6). Conclusion: CMV infection diagnosed by CMV pp65 antigenemia assay is not rare during high dose corticosteroid therapy for collagen vascular diseases, and advanced age is considered a risk factor for it. It has a variety of symptoms and laboratory findings, which are mild and nonspecific to this type of infection, and they may not be clearly noted as clinical signs of CMV infection, even in patients with CMV diseases whose prognoses can be unsatisfactory. During high dose corticosteroid therapy for collagen vascular diseases, careful attention should be paid to CMV infection.
