Hypothesis
What are the predominant Mycobacterium tuberculosis strains and their drug susceptibility patterns in Kampala, Uganda?
Conclusion
The TB epidemic in Kampala is mainly caused by the T2 family of strains, which are not associated with drug resistance or HIV sero-status.
Supporting Evidence
- 241 out of 344 isolates were of the T2 family, making it the predominant strain.
- Resistance to isoniazid was found in 8.1% of strains, while all rifampicin-resistant strains were multi-drug resistant.
- 92 patients (26.7%) were HIV sero-positive, with no significant association between strain types and HIV status.
Takeaway
In Kampala, a lot of people have tuberculosis caused by a specific type of germ called T2, and this type doesn't seem to be affected by whether someone has HIV or not.
Methodology
This was a cross-sectional study of newly diagnosed sputum smear-positive patients aged ≥ 18 years, with 344 isolates genotyped and drug susceptibility tested.
Potential Biases
Potential bias in participant selection as only those who consented to HIV testing were included.
Limitations
The study may not represent all TB cases in Uganda as it focused on a specific peri-urban area.
Participant Demographics
The sample included 344 patients, with 47.4% female and 52.6% male, median age 32 years.
