Optimized anti-tuberculosis duration for drug-susceptible pulmonary tuberculosis-diabetes mellitus comorbidities: study protocol for a multicenter randomized controlled trial
Abstract
Background: The coexistence of tuberculosis (TB) and type 2 diabetes mellitus (DM) presents unique challenges in treatment optimization and management, given the mutual exacerbation of disease processes.
Objective: This multicenter, open-label, randomized controlled trial aims to evaluate the efficacy and safety of two different treatment durations (6-month versus 9-month regimens) regimen for patients with drug-susceptible pulmonary tuberculosis (DS-PTB) and concurrent type 2 diabetes (DM).
Methods: Patients with DS-PTB and type-2 DM from 22 hospitals in China are enrolled. They are randomized in a 1:1 ratio into either the 6-month regimen arm(2HRZE/4HR) or the 9-month regimen arm(2HRZE/7HR). At the end of the intensive phase (the 8th week), patients in both arms who with sputum positive smear will extent one more month of intensive treatment. The primary outcome is the proportion of unfavorable outcomes at 24 months after randomization. Secondary outcomes include treatment success rate at the end of treatment, proportion of recurrence at 24 months after randomization, time to recurrence after treatment completion, proportion of intensive phrase extension, occurrence of adverse events grade 3 or above during treatment.
Discussion: The study focuses on assessing the optimal treatment duration to maximize treatment success while minimizing recurrence and adverse events. The trial is expected to provide vital insights into the appropriate treatment duration for patients with…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
