Hypothesis

What are the reasons for clinical deterioration in tuberculosis patients undergoing antitubercular treatment in a high HIV-1 prevalence setting?

Conclusion

New AIDS defining illnesses, drug resistant M.tb, and other drug resistant bacteria are significant reasons for clinical deterioration in HIV-1 co-infected patients receiving antitubercular treatment.

Supporting Evidence

  • 296 out of 352 TB patients were admitted to the hospital, accounting for 17% of total medical admissions.
  • Mortality among TB patients admitted to hospital was 16%.
  • 72% of TB patients had an additional illness to tuberculosis.

Takeaway

This study looked at why some people with tuberculosis get worse while being treated, especially those who also have HIV. It found that other illnesses and drug-resistant bacteria are big problems.

Methodology

A prospective observational study conducted at GF Jooste Hospital, collecting data on TB diagnosis, treatment, HIV-1 status, and reasons for clinical deterioration.

Potential Biases

Referral bias due to strict admission criteria may affect the generalizability of the findings.

Limitations

The study design within routine care in a busy setting may lead to referral bias and underestimation of the problem.

Participant Demographics

83% of TB patients were HIV-1 co-infected, with a median CD4 count of 89 cells/mm3.
