Severe primary HIV-1 infection among black persons in Barbados

ABSTRACT

Descriptions of primary HTV-1 infection have so far been based on Caucasians living in industrialized nations. Due to studies of leptospirosis in predominantly black population of Barbados, serum was available for patients admitted with acute febrile illnesses to the Queen Elizabeth Hospital (QEH). By searching the medical records of 510 adult patients with known HIV-1 infection we identified 10 patients who had stored serum from an admission for an acute febrile illness that predated or coincided with their first HIV-1-positive test. Serological testing confirmed primary HIV-1 infection in 9 and was suggestive in the 10th patient. The clinical features of these 10 patients were in keeping with previous descriptions of primary HIV-1 infection but differed from leptospirosis cases seen at the QEH. One patient died during the seroconversion illness and another died 3 months after seroconversion. The findings suggest that severe primary HIV-1 infection could be a relatively uncommon occurence, that the condition may be misdiagnosed, and that cases may not occur until the AIDS epidemic is established.(AU)
