The first-three year report of the Tuberculosis Control Project, Lumbini, Rupandehi

Abstract

The Tuberculosis Control Project, Lumbini, Rupandehi (TCPLR) is a bilateral cooperative venture between two NGO's, the Nepal Anti-Tuberculosis Association (NATA) and the Japan Anti-Tuberculosis Association (JATA), which consists of planning and implementing pilot tuberculosis control activities in Lumbini, Rupandehi district in Nepal, aiming at achieving high cure rate of newly detected smear-positive pulmonary tuberculosis patients before introducing DOTS strategies. Between December 1993 and July 1996, 349 tuberculosis (TB) cases were enrolled in the TCPLR. The categories of cases were as follows: 138 cases (40%) of new smear-positive pulmonary TB [new Sm(+) PTB], and 54 cases (15%) of smear positive pulmonary TB other than new Sm(+) PTB [other Sm(+) PTB] including such cases as continued treatment and relapse, 106 cases (30%) of new smear-negative TB [new Sm(-) TB], and 51 cases (15%) of other smear-negative TB other than New Sm(-) PTB [other Sm(-) TB]. The number and proportion of new Sm(+) PTB cases enrolled in the project have been increasing [6 cases (23%) for the first year, 102 cases (54%) for the third year] although the proportion is still low (40% overall). The regimens of chemotherapy in the initial intensive and the continuation phases of treatment according to the categories of TB were as follows: New Sm(+) PTB; 2HRZE(S)/6HE, other Sm(+) PTB; 2HRZES/1HRZE/5HRE, and Sm(-) TB; 2HRZ/6HE. The proportion of cases treated by the appropriate regimen of chemotherapy has increased. The cohort analysis of the treatment outcome of the cases enrolled in the project showed the following. The proportion of cured cases plus smear-unconfirmed cases completing treatment among new Sm(+) PTB was 74% overall, however, the proportion of defaulters increased in the third year. The proportion of cured cases plus smear-unconfirmed cases completing treatment among other Sm(+) PTB cases was 66% overall, which is slightly lower than that of new Sm(+) PTB cases, however, the difference was not so marked. The proportion of treatment completed cases among smear-negative pulmonary TB cases was 77% overall, however, proportion of defaulters increased in the third year. The treatment outcome in this report was obtained before the adoption of DOTS strategies: However, it showed that cure and treatment completion rates were comparable to those obtained in the SEARO countries which adopt DOTS strategies. The treatment outcome could be improved after the introduction of DOTS strategies in 1997.
