BackgroundThe number of people infected with tuberculosis continues to rise world-wide. Rifampicin-containing treatment regimens can achieve high cure rates. Intermittent drug treatment delivered in the community has the potential to improve adherence to treatment.ObjectivesThe objective of this review was to compare the effectiveness of rifampicin-containing short-course chemotherapy regimens, given two or three times a week, with similar regimens given daily in patients with pulmonary tuberculosis.Search StrategyWe searched the Cochrane Infectious Diseases Group trials register, the Cochrane Controlled Trials Register, Medline, and reference lists of articles. We contacted experts in the field.Selection CriteriaRandomised and quasi-randomised trials of any multi-drug regimen containing rifampicin in patients with confirmed pulmonary tuberculosis. Treatment had to be given up to three times a week for up to nine months, with any initial daily dosing period not more than one month, and was compared to daily dosing throughout for the same period.Data Collection And AnalysisTwo reviewers independently assessed trial eligibility and quality.Main ResultsOne trial involving 399 patients was included. The trial compared treatment three times per week with daily treatment for six months. There was no difference in cure rate (198 out of 199 people in the intermittent group compared to all 200 in the daily group), but 5 patients relapsed in the group receiving intermittent therapy compared to one in the group receiving the daily regimen.Reviewer's ConclusionsThere is not enough evidence to assess the equivalence of effect between fully intermittent, rifampicin-containing short-course chemotherapy and similar daily therapy in patients with pulmonary tuberculosis. Larger randomised studies are required to establish the effectiveness of fully intermittent, short-course chemotherapy.
