A Study on the Short - Course Treatment Regimen Containing Pretomanid for Diabetes Mellitus Complicated With Rifampicin - Resistant/Multidrug - Resistant Pulmonary Tuberculosis

Обзор

The treatment of rifampicin-resistant/multidrug-resistant pulmonary tuberculosis (RR-TB) is characterized by a long treatment course, a high incidence of adverse reactions, a low cure rate, and a high recurrence rate. This is related to the large number of drugs in the RR-TB treatment regimen, the high incidence of adverse reactions, and the long treatment course, which lead to poor patient compliance. There is an urgent need for new, effective, safe, and short-course anti-drug-resistant regimens. A 6-month short-course oral regimen containing pretomanid was launched in 2020 and was approved for marketing in China in March 2025. Currently, there have been multi-center studies on the treatment of rifampicin-resistant/multidrug-resistant pulmonary tuberculosis with the pretomanid regimen initiated by investigator-initiated trials (IIT) in China, but there are no studies on special populations. The diabetic population belongs to a special population, has a relatively high incidence rate in China, and is at high risk of tuberculosis. During the treatment process, they may be more likely to experience adverse reactions and poor outcomes than ordinary patients. This study is a prospective cohort clinical study. It is planned to enroll patients aged ≥12 years with RR/MTB-TB complicated by diabetes at our center. Guided by the results of rapid molecular drug susceptibility testing, both groups will be treated with a regimen consisting of bedaquiline, pretomanid, linezolid, and moxifloxacin for 6 months. The experimental group will be diabetic patients, and the control group will be non-diabetic patients. The efficacy and safety of the two groups will be evaluated to provide a basis for the treatment of a new short-course drug-resistant regimen for RR/MDR-TB in special populations in China.
