# Treatment of asymptomatic tuberculosis: Protocol for a systematic review of treatment strategies, regimens, and clinical outcomes

## TL;DR

This paper outlines a systematic review protocol to evaluate treatment strategies for asymptomatic tuberculosis, aiming to guide future clinical practices.

## Contribution

The study introduces a systematic review protocol to assess treatment regimens and outcomes for asymptomatic TB patients.

## Key findings

- The review will analyze treatment outcomes such as success rates and adverse events in asymptomatic TB.
- It will identify gaps in current treatment strategies to inform simplified or tailored regimens.
- Findings will support evidence-based decisions for global TB control.

## Abstract

Asymptomatic tuberculosis (TB) is increasingly recognised through active case finding and prevalence surveys. However, treatment strategies for this patient group remain poorly defined, and there is no consensus on optimal regimens, duration, or outcomes.

We will conduct a systematic review of observational and interventional studies reporting anti-TB treatment in patients with asymptomatic TB. Databases including MEDLINE, Embase, Scopus, Web of Science, CINAHL, and the Cochrane Library will be searched without language restrictions. Outcomes of interest include favourable outcome rate, treatment coverage, success rate, relapse, mortality, loss to follow-up, adverse events, and patient-reported outcomes such as pill burden and treatment discontinuation. Study selection, data extraction, and quality assessment will be performed independently by two reviewers, following PRISMA guidelines. Where appropriate, meta-analyses will be conducted using a random-effects model.

This review will provide a comprehensive synthesis of current evidence on the treatment of asymptomatic TB. It aims to inform future clinical and public health strategies, including the potential for simplified or shortened treatment regimens tailored to this population. By identifying gaps and inconsistencies in current practice, the findings will support evidence-based decision-making and contribute to global TB control efforts.
