Immuno-hematological parameters among adult HIV patients before and after initiation of Dolutegravir based antiretroviral therapy, Addis Ababa, Ethiopia.

BACKGROUND

Immuno-hematological abnormalities are common among HIV infected individuals as well as patients with highly active antiretroviral therapy (HAART). However, the immuno-hematological outcome of Dolutegravir based antiretroviral therapy (ART) usage is not well investigated.

OBJECTIVES

To assess hematological and immunological parameters among adult HIV patients before and after initiation of Dolutegravir based ART regimen at St. Peter Specialized Hospital, Addis Ababa, Ethiopia.

METHODS

A cross-sectional study was conducted from May to July 2021 at St. Peter Specialized Hospital among adult HIV patients. A total of 422 HIV patients on Dolutegravir based ART (combination of Dolutegravir/lamivudine/tenofovir disoproxil fumarate (DTG/3TC/TDF)) for a minimum of 3 months were selected using convenient sampling methods. Socio-demographic as well as clinical data of the participants was obtained using pre-tested structured questionnaires and a review of medical records. Hematological parameters such as CBC was obtained using Beckman coulter automated hematology analyzer and immunological parameters such as CD4 count were determined using BD FACS presto. Statistical analysis of the data was done using SPSS version 21. Paired t-test was used to compare dependent variables before and after initiation of the new HAART and binary logistic regression was used to determine predictors of immuno-hematological abnormalities. P-value < 0.05 was considered as statistically significant.

RESULTS

Of 422 adult HIV patients, about 273(64.7%) were females. The mean age of study participants was 42.2 years (±10.4SD). The mean white blood cell (WBC) count, red blood cell (RBC) count, hemoglobin (Hb), platelet distribution width (PDW), CD4 count, as well as lymphocyte percentage, neutrophil percentage, and platelet counts (PLT) were increased significantly(P<0.05) after 3 months of the Dolutegravir based therapy. While, red cell distribution width (RDW) and mean cell hemoglobin (MCH) were decreased (P<0.05) after the treatment. Other hematological parameters such as mean cell volume (MCV), hematocrit (HCT), mean cell hemoglobin concentration (MCHC), mean platelet volume (MPV) and platelet distribution width (PDW) showed no significant change. On the other hand, the most common hematological abnormalities identified after the new HAART were anemia (12.1%); followed by Leucopenia (11.3%), neutropenia (6%), and thrombocytopenia (4%). Anemia was associated with female sex (AOR = 7.8, 95% CI: 1.9-32.2, P<0.005) and WHO clinical stage III/IV (AOR = 16, 95% CI: 10.63-66.46, P<0.01).

CONCLUSION

There was a significant change in certain immuno-hematological parameters such as WBC count, RBC count, PLT count, Hb, PDW, CD4 count, lymphocyte and neutrophil percentage after initiation of the Dolutegravir based therapy. Anemia was the most common hematological abnormality. Further studies are required to fully comprehend the outcome of the new treatment regimen on immuno-hematological parameters.
