  Abstract 

Childhood tuberculosis (TB) is a common clinical condition in low- and middle-income nations like India where TB is endemic. Different guidelines vary in the recommendations on treatment regimes for childhood TB. Apart from clinical outcomes the decision to use one regimen over another also has an implication in the form of health system burden. The evidence summary presents the comparison between the intermittent regimens with the daily anti-TB regimen for childhood TB.

  Background Top


The World Health Organisation, British Thoracic Society and the Revised National Tuberculosis Control Programme (RNTCP), India, guidelines recommend daily or thrice weekly intermittent therapy for childhood tuberculosis. On the other hand the American Thoracic Society and the Centers for Disease Control and Prevention (CDC), recommends a daily or twice-weekly regimen.

Such differences in guidelines have meant clinicians prescribing a myriad of regimens with varying efficacy and safety. The control of childhood TB is an important part of the global "Stop TB" strategy. Even small incremental efforts to control childhood TB are important since prevalence of childhood TB in a community is a potent indicator of ongoing TB transmission.

How was the study done?

Researchers in The Cochrane Collaboration conducted a systematic review and meta-analyses [1] comparing the safety and efficacy of the of intermittent, short-course anti-TB regimens (twice- or thrice weekly) with daily short-course anti-TB regimens in the treatment of childhood TB (5 months-15 years).

What did the study find?

After searching for relevant studies, researchers identified four randomized controlled trials enrolling 563 children for the comparison between intermittent twice weekly versus daily anti-TB treatment. No randomized controlled trials which compared between the thrice weekly anti-TB short-course regimen and the daily treatment regimen for childhood TB were found. A summary of what the researchers found is depicted in [Table 1]. Researchers found no difference between twice weekly and daily intermittent childhood TB regimens for achieving cure, adherence to treatment, and death from any cause or treatment limiting adverse events. The research evidence is generally of very low quality. This means we are very uncertain about the differences in estimates for the outcomes in the form of cure; all cause death, relapse, adherence to treatment and treatment-limiting adverse events between intermittent twice weekly and the daily schedule for treating childhood TB.

Implications for clinical practice

There is insufficient evidence to support or refute the usage of either regimens in actual practice.

Implications for research

The review points to the need for conducting properly designed randomised controlled trials in high TB-transmission settings, in low- and middle-income countries in order to resolve the issue of different regimens in various national and international guidelines for treating childhood TB.

Conclusion

Trials conducted till now are insufficient to either support or refute the use of either schedule of anti-TB drugs for childhood TB. More research is needed to answer which is better than the other in terms of outcomes.

This evidence summary is based on the following systematic review

Bose A, Kalita S, Rose W, Tharyan P. Intermittent versus daily therapy for treating tuberculosis in children. Cochrane Database of Systematic Reviews 2014, Issue 1. Art. No.: CD007953. DOI: 10.1002/14651858.CD007953.pub2

What is a systematic review?

A systematic review seeks to answer a well-formulated and specific question by identifying, critically appraising, and summarizing the results of all relevant studies, published and unpublished, according to explicit and transparent methods. Systematic reviews of randomized controlled trials, like the current one, occupy the highest position in the hierarchy of evidence.

How was quality of evidence assessed?

The quality of evidence has been assessed using methods developed by the GRADE working group (www.gradeworkinggroup.org). The WHO Guidelines Review Committee also uses the GRADE system.
