Lung Health and the Microbiome in Botswana: The Go-hema Cohort
Official title: Determinants of Lung Health Among Batswana Adults With and Without HIV: the Go-Hema Study
Run by Duke University · NCT07699614 · Data updated 2026-11-12
We are testing how lung function patterns and the microbiome relate to COPD and related lung issues in adults in Botswana, including people with HIV.

Is this trial a fit for you?
✓Likely a good fit
Adults 35 years or older in Botswana with documented HIV status who can provide informed consent and perform spirometry.
✕Probably not a fit
Individuals who do not have COPD or related lung function impairment, or those unable to complete spirometry, may see no direct benefit.

What this trial studies
This is a prospective cohort study in Botswana that aims to characterize abnormal lung function patterns and explore associations between the host microbiome and COPD outcomes. Researchers will use multi-omics approaches to analyze data from adults with and without HIV to understand how microbiome interactions may influence lung health and disease progression. The study focuses on data collection from local health facilities in Gaborone to improve understanding of COPD in a population underrepresented in current research. Findings could help inform more equitable approaches to COPD prevention and therapy for populations similar to Botswana.
Why it matters
Potential benefit: If successful, the study could improve understanding of COPD drivers in Botswana and contribute to developing tailored prevention and treatment strategies for populations with high HIV prevalence.
How similar studies have gone: Previous studies in other regions have linked microbiome patterns with COPD, but this cohort addresses a population that has been underrepresented in such research.
