BACKGROUND: Better understanding of HIV-2 infection is likely to affect the patient care in areas where HIV-2 is prevalent. In this study, we aimed to characterize the clinical presentations among HIV-1, HIV-2 and HIV-1/2 dual seropositive patients.

METHODS: In a cross-sectional study, newly diagnosed HIV patients attending the HIV outpatient clinic at Hospital Nacional Simão Mendes in Guinea-Bissau were enrolled. Demographical and clinical data were collected and compared between HIV-1, HIV-2 and HIV-1/2 dual seropositive patients.

RESULTS: A total of 169 patients (76% HIV-1, 17% HIV-2 and 6% HIV 1/2) were included in the study between 21 March 2012 and 14 December 2012. HIV-1 seropositive patients were younger than HIV-2 and HIV-1/2 seropositive patients, but no difference in sex was observed. Patients with HIV-1 and HIV-1/2 had a lower baseline CD4 cell count than HIV-2 seropositive patients (median CD4 cell count 185, 198 and 404 cells/μl, respectively (p value 0.001 and 0.05). HIV-1 seropositive patients had a lower BMI and a higher prevalence of weight loss, skin rash and productive cough than HIV-2 seropositive patients (p value 0.03, 0.002, 0.03 and 0.04). Only four cases (2%) of pulmonary tuberculosis (TB) were diagnosed. One patient (1/96, 1%) was tested positive for cryptococcal antigen.

CONCLUSION: HIV-1 and HIV-1/2 seropositive patients have lower CD4 cell counts than HIV-2 seropositive patients when diagnosed with HIV with only minor clinical and demographic differences among groups. Few patients were diagnosed with TB and cryptococcal disease was not found to be a major opportunistic infection among newly diagnosed HIV patients.
