In a study of feasibility of treatment of smear
positive patients with Short Course Chemotherapy (SCC) regimens
under District TB Programme (DTP) conditions in a city, adverse
drug reactions in terms of frequency of episodes, incidence in the
cohort of patients, time of occurrence, major adverse reactions
requiring modification of chemotherapy and or symptomatic treatment,
Patients were allocated to one of the two 8 month
SCC regimens i.e., Regimen 'A' 1 SHRZ/6TH, Regimen 'B' 2SHR/6TH.
Overall incidence of adverse drug reaction in cohort of 265 patients
was 37%, 9% of which were considered as major in nature. 34 episodes
of such reactions resulted in modification of chemotherapy in 15
patients during intensive phase. Though gastro intestinal symptoms
were predominant, cutaneous toxicity was the pre eminent cause of
modification of regimen. No case of exfoliative dermatitis occurred.
A total of 333 episodes of adverse drug reactions of minor nature
occurred; 50% being gastro intestinal symptoms followed by cutaneous
symptoms. More than 70% of all adverse drug reactions of intensive
phase occurred in the first half of the period. There was no significant
difference between the two regimens in the incidence of adverse
drug reactions of either major or minor in nature.
SCC is being implemented in a phased manner in
the DTP. Before introducing SCC in large number of districts, it
would be prudent to find out whether SCC would be acceptable to
both doctor and patient in terms of adverse drug reactions.
It can, therefore, be concluded that adverse reactions may not be
a major constraint for inclusion of SCC under DTP for treating sputum
positive tuberculosis patients provided that additional resources
and man power are allocated to the DTCs to manage patients in the
centre and extend effective guidance to staff working in peripheral
