BackgroundAlthough anti-retroviral therapy has generally improved the survival of HIV infected patients in many developing countries including Ghana, specific socio-demographic factors could still influence outcome of treatment. This study was designed to identify patient-specific factors that could influence the immune recovery of absolute CD4 count in HIV infected patients.

FindingsHospital records were extracted from two health facilities in Ghana. The impact of socio-demographic factors type of ART and baseline category of CD4 counts were assessed at six monthly interval using robust linear mixed models.

ResultsA total of 214 follow up records were reviewed at Komfo Anokye Teaching Hospital KATH and the Kumasi South Hospital KSH. One hundred 46.7 % were from KATH and 114 53.3 % were from KSH. There was a general increase in the level of CD4 counts with time, however this increase significantly slowed down with subsequent reviews p < 0.001. On the average the rate of CD4 count recovery slowed down by 43.6 cells-µl for every 6 months of follow up SE = 7.69; p < 0.001. Similarly the recovery of CD4 counts in subjects with an initial high baseline CD4 counts decreased by 192.6 cells-µl SD error = 42.3, p value ≤0.001. All other variables were not significantly associated with recovery of CD4 counts.

ConclusionOur study has demonstrated the well-known phenomenon of CD4 counts increasing after administration of ARTs. CD4 counts increased more rapidly in those with relatively lower initial counts, catching up with those with high CD4 count by 2 years post treatment.
