BACKGROUND: Drug-resistant tuberculosis (DR-TB) poses a significant threat to global TB control and remains a major public health issue. This study aims to evaluate treatment outcomes and identify risk factors for unfavorable outcomes in patients with multi-DR-TB (MDR-TB) treated at a major reference hospital in Istanbul.
METHODS: We conducted a retrospective analysis of 413 patients with rifampicin-resistant and MDR-TB who received treatment between January 1, 2013, and December 31, 2023, at the University of Health Sciences Süreyyapaşa Chest Diseases Training and Research Hospital. Patients were treated following the World Health Organization and national guidelines, with regimens tailored to individual drug resistance profiles and side effect management. Demographic data, comorbidities, microbiological follow-up, drug resistance patterns, treatment regimens, and radiological findings were analyzed.
RESULTS: Treatment success was achieved in 350 patients (84.74%). Thirty-two patients (7.74%) were lost to follow-up, and 32 patients (7.74%) died. Logistic regression analysis identified several factors associated with unfavorable treatment outcomes: comorbidities (odds ratio [OR]: 7.555, P = 0.001), quinolone resistance (OR: 3.695, P = 0.030), and bronchiectasis (OR: 4.126, P = 0.013). Additional significant factors included male gender (P = 0.007), foreign-born status (P = 0.013), age over 35 years (P = 0.002), previous treatment history (P = 0.058), and drug side effects (P = 0.012).
CONCLUSION: The long-term regimen for MDR-TB was found to be highly successful, with an 84.74% treatment success rate. Effective treatment regimens, close patient follow-up, early recognition of side effects, and comprehensive management are crucial for achieving successful outcomes. Identifying and addressing risk factors such as comorbidities, drug resistance, and specific patient demographics can further improve treatment success rates. This study underscores the importance of tailored treatment strategies and robust patient management in combating MDR-TB.
