Prognostic markers in HIV mono-and co-infected individuals: A study from Karachi–Pakistan

摘要

Background Multiple infections are the most common problem among HIV infected individuals. The prognostic impact of these co infections in HIV-population in resource-limited countries like Pakistan has not been fully elucidated. The aim of this study was to assess CD4 and hemoglobin (Hb) levels in patients with HIV mono infection and HIV co-infection with Hepatitis C (HCV), Hepatitis B (HBV) and Mycobacterium tuberculosis (MTB). Methods A total of 207 HIV positive patients were assessed for CD4 cells count and hemoglobin levels after confirmation of HIV by rapid tests as well as PCR. CD4 counts were performed via flow cytometry whereas hemoglobin levels were performed by Sysmex K-4500 auto-analyzer. Results Out of 207 patients, 22 patients were found to be HIV mono-infected, while 185 patients were HIV positive along with co-infections of MTB or HCV or HBV. We found significant positive correlation between HB levels and CD4 count across the studied group (r = 0.30 in HIV mono-infected group, r = 0.23 in HIV co-infected group, p Conclusion This study documents the prognostic value of hemoglobin assessment in HIV patients. The results indicate that decreasing Hb levels correlate with decreasing CD4 counts. It is emphasizing that Hb measurement may be used as an inexpensive surrogate marker as compared to CD4 analysis for disease progression in HIV patients. In addition, low Hb levels may also indicate presence of under lying co-infections, particularly, with M. tuberculosis (MTB).
