Affecting Factors Unfavorable Treatment Outcomes of Rifampicin-resistant/Multidrug-resistant Tuberculosis Patients Treated with Long-term Regimen.

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.

Nontuberculous mycobacteria isolation from sputum specimens: A retrospective analysis of 1061 cases.

The primary aim of this study was to evaluate the clinical significance of therapeutic drug monitoring (TDM) growths in respiratory samples, and the secondary aim was to evaluate the treatment regimens and treatment outcomes of treatment for TDM disease.

Miliary tuberculosis: Epidemiologicaland clinical analysis of large-case series from moderate to low tuberculosis endemic Country.

The aim of this study was to determine the clinical features, and outcome of the patients with miliary tuberculosis (TB).We retrospectively evaluated 263 patients (142 male, 121 female, mean age: 44 years, range: 16-89 years) with miliary TB. Criteria for the diagnosis of miliary TB were at least one of the followings in the presence of clinical presentation suggestive of miliary TB such as prolonged fever, night sweats, anorexia, weight loss: radiologic criterion and pathological criterion and/or microbiological criterion; pathological criterion and/or microbiological criterion.
