Exploring diseases burden in HIV population: Results from the CHAO (Comorbidities in HIV/AIDS outpatients) cross-sectional study in Kenya

Background: Africa is the epicenter of the HIV epidemic, with over two-thirds of the global population living with HIV. It is also facing a dramatic increase in non-communicable diseases (NCDs) amidst its aging population. This necessitates a healthcare approach that addresses both infectious diseases and NCDs in HIV-positive individuals. In Kenya, with 1.4 million HIV-positive people, efforts include widespread ART access and integrating HIV services into the health system. Challenges remain in healthcare infrastructure, particularly in rural areas. The Comorbidities in HIV/AIDS Outpatients (CHAO) Project, funded by the Italian Cooperation Agency, aims to improve understanding and management of comorbidities in HIV patients, highlighting the need for cost-effective healthcare strategies to address this dual burden. Methods: The CHAO (Comorbidities in HIV/AIDS Outpatients) project conducted a cross-sectional epidemiological study across 25 clinics in Meru County, Kenya. The study included comprehensive surveys and screenings for various comorbidities among HIV-positive patients receiving treatment, utilizing both clinical evaluations and laboratory tests to assess the prevalence of infectious diseases and NCDs. Results: A total of 1051 HIV-positive individuals were included in the study: 75 % females, 25 % males, median age 47 years, the majority (96 %) on long-term ART, mostly Dolutegravir-based (95 %). 55.4 % had at least one comorbidity, with NCDs such as dyslipidemia (21.22 %) and hypertension (20.17 %) being the most prevalent. The study also noted significant occurrences of communicable diseases, including syphilis (5.23 %), hepatitis B (2.19 %), and hepatitis C (0.29 %). The prevalence of comorbidities varied with age, highlighting the impact of aging on disease burden. Discussion: The high prevalence of comorbidities among HIV-positive patients in Meru County underscores the need for integrated healthcare strategies that address both infectious diseases and NCDs. The findings advocate for systematic screening and management of comorbidities within HIV care programs, emphasizing the need for holistic health approaches to improve outcomes for this population.
