Health-Related Quality of Life and CD4 cells status of Patients receiving Antiretroviral Therapy in Nigeria
Main Article Content
Abstract
Background: The goals of antiretroviral therapy (ART) are to improve patient's health-related quality of life (HRQOL) and restore immunologic function among others.
Objectives: The study evaluated HRQOL and CD4-cells response of HIV-infected patients at months 0 and 6 of receiving ART in Maitama District Hospital Abuja, Nigeria.
Methods: HRQOL of a cohort of 150 HIV-infected patients was evaluated at months 0 and 6 of receiving ART using Medical Outcomes Study Short Form-36 (MOS SF-36) which has 8 domains. These include physical functioning, physically and emotionally related role limitations, social functioning, pain, energy/fatigue, emotional well-being and general health. A paired samples t-test was used to compare the HRQOL scores and CD4 cells count of participants at months 0 and 6. Wilcoxon's signed-ranks test was used to compare HRQOL of male and female participants. At two-tailed test, p value of <0.05 was considered significant.
Results: The mean age (±SD) of the 150 participants at ART initiation was 34.3 ± 8.4 years; 59.3% were females. The mean (±SD) HRQOL of participants increased significantly from 71.9% ± 20.9 at ART initiation to 89.7% ± 10.6 after 6 months of ART (p<0.05). The change in all SF-36 domains was statistically significant (p<0.05) except for the domains of role limitation due to emotional problems, social functioning and pain. The improvement in the mental component score (MCS) was significant (p<0.05) unlike that of the physical component (PCS). The difference in the HRQOL of male and female participants at months 0 and 6 was not significant. The mean CD4 cell count (±SD) increased from 185.7 ±91.0 cells/mm3 at month 0 to 199.0 ±104.7 cells/mm3 after 6months of ART; though this increase was not statistically significant.
Conclusion: There was significant improvement in the mean HRQOL scores of participants which was not associated with significant improvement in the CD4 cells status after six months of ART. The evaluation of HRQOL alongside the clinical and immunological parameters when monitoring treatment outcomes is recommended.
