Background

The co-infection of Mycobacterium tuberculosis (M. tuberculosis) and Human Immunodeficiency Virus (HIV) represents a significant battle for public health worldwide. In the West Region of Cameroon, understanding how treatment outcomes for tuberculosis (TB) differ among age groups of HIV patients is essential for improving healthcare strategies. This study aimed to uncover critical data on how age impacts TB treatment success among HIV co-infected individuals.

Methods

A thorough examination was conducted involving 2,455 TB patients from the West Region of Cameroon, who were receiving treatment from January 2015 to December 2019. This comprehensive cross-sectional study analyzed data from the National Tuberculosis Program Registers, utilizing multivariate logistic regression to determine the relationship between treatment outcomes, HIV status, and age.

Results

Alarmingly, those who were co-infected with TB and HIV had significantly lower rates of TB treatment successes. For HIV-positive patients on antiretroviral therapy (ART), the odds of treatment success had an odds ratio (OR) of 0.463. That ratio plummeted to 0.077 for those not undergoing ART, clearly indicating that therapy plays a vital role in recovery. Furthermore, older age correlated with lower treatment success rates, pointing to a troubling trend where individuals aged 25 and older experience the worst outcomes, especially those not on ART.

Conclusion

This study has unveiled a crucial connection between age, HIV status, and TB treatment outcomes. The findings clearly indicate that older HIV-positive patients, particularly those not receiving ART, face ultra-high risks of poor treatment results. To combat this crisis and improve treatment success rates, Cameroon's healthcare strategy must integrate robust TB and HIV services, emphasizing routine follow-ups and patient management.

Global Perspective on TB and HIV Co-Infection

The combination of TB and HIV is a growing concern not only in Cameroon but across developing nations. Globally, TB remains the primary cause of death among HIV patients, and about one-third of HIV patients are believed to be affected by TB. Notably, in 2021, Cameroon had a TB incidence rate of 164 per 100,000 people—a staggering statistic that underscores the urgency for targeted interventions.

The Urgency of Treatment Integration

These findings highlight a critical need for integrated healthcare approaches that can effectively address the complex interactions between TB and HIV, particularly for vulnerable populations such as the elderly. As the study emphasizes, ensuring access to ART immediately upon TB diagnosis could potentially lead to a remarkable 60% reduction in mortality rates.

Call to Action

This study serves as a wake-up call for healthcare authorities to prioritize TB and HIV management in their healthcare policies. Enhancements in diagnostic technology, improved treatment protocols, and increased community awareness are essential to combat this alarming trend of treatment failures among older adults with co-infections. It's time for to take action before we face an even graver public health crisis!
