Initiation of MDR TB treatment: is hospitalization worth?

BACKGROUND: The treatment for MDR TB is quite prolonged and associated with adverse effects and hence costly. AIM: The aim of study was to study the side-effects of reserve line drugs developing in initial seven days of starting therapy, so as to weigh the need for admission for initiation of treatment against heavy economic burden by admission of huge number of MDR TB patients, and to identify the factors which may have an effect on the number of patients developing side-effects METHODS: All MDR TB patients (930) admitted during study period, who were initiated on Cat IV treatment for MDR TB under RNTCP were questioned daily for any side-effects throughout the day, during initial seven days of treatment. RESULTS: On day one, 342 (36.8%) patients developed side-effects, on 2nd day 456 (49%), on day 3 356 (38.3 %), on fourth day 257 (27.6%), then on fifth day only 172 (18.5 %) patients respectively had reported side-effects. Further decline of side-effects was reported on sixth day 94(10.1%) and seventh day 39(4.2%). Number of events also decreased from 669 on dayl and 965 on day 2, to only 61 on day 7 of treatment. Most of the patients had nausea, vomiting, pain abdomen, restlessness, dizziness, insomnia and headache. Patients with low Hemoglobin had more side-effects from day 2 onwards (p<0.05).Age, BMI, gender and co-morbidities had no significant effect on side-effects in these patients. CONCLUSION: Many patients report side-effects initially on treatment, which gradually decrease from day 4 onwards , so hospitalization for atleast seven days during initiation of Cat IV may not be required in all the patients.

Sputum smear positivity at two months in previously untreated pulmonary tuberculosis patients.

BACKGROUND AND OBJECTIVES: In pulmonary tuberculosis, bacteriological status at two months affects subsequent treatment and prognosis. The effect on treatment outcome and risk factors for sputum conversion at two months treatment in previously untreated pulmonary tuberculosis (PTB) patients was studied in the following report. METHODS: A 1:1 case-control study was performed from June 2006 to February 2008 on patients in the Revised National Tuberculosis Control Program in a tertiary level institute in Delhi, India. Patients with previously untreated PTB with sputum smear positive at 2months of treatment (cases) were compared with those who achieved conversion (controls). RESULTS: In 74 cases and 74 controls, independent risk factors for sputum smear positive at two months were: illness for >2months, presence of cavity or extensive disease on chest X-ray, and interruption in intensive phase of treatment. Patients with smear positive at 2 or 3months of treatment were more likely to fail or default from treatment. Aforesaid factors were also associated with sputum culture positive status at 2months in univariate analysis. Patients who interrupted treatment ⩾3 times in the first two months were more likely to be culture positive at two months and had a higher rate of default and failure. CONCLUSIONS: Illness for more than 2months, presence of cavity or extensive disease on chest X-ray, and interruption in intensive phase of treatment are independent risk factors for sputum smear positivity at two months, which in turn is associated with poor treatment outcomes. Patients with these factors merit special attention under the national program.
