Method: This retrospective cohort study was conducted from April 2010–September 2013 at ART clinic of Hawassa University referral hospital.

Results: mean CD4+ cells count shows significant increment at 6, 12, 18 and 24 months after ART treatment among patients having VL <5 (log10) compared to those VL ≥5 (p=0.04; 0.002; < 0.0001; 0.001) respectively.

But, in relative to younger patients, their CD4 cells recovery is insignificantly sluggish. CD4+ cells and body weight of concordant positive responders show significant rising trend at 6, 12, 18, 24 months when compared to discordant responders + concordant non-responders, and p-value: (0.003 vs. 0.05; <0.0001 vs. 0.04; 0.001 vs.0.008; 0.001 vs.0.03) respectively. Moreover logistic regression models were applied and significant factors associated with discordant immuno-virological response were patient’s body weight (AOR=0.14; 95% CI: 0.03-0.7; p=0.02) and residence (AOR=20.3; 95% CI: 2.2-188; p=0.008). Conclusion: Immuno-virological response assessment is a critical tool for addressing treatment outcome, regimen change and patient’s management for those peoples living with HIV using ART. Therefore we recommend that treatment response decision should include both CD4+ cells count and viral load concurrently.},
