ABSTRACT
Introduction: At the National Institute of Respiratory Disease, information on secondary pharmacoresistance is available since 1991. Considering the importance of this topic as indicator of the efficiency in antituberculous treatment, information was revised from 1991-1993 and from 1994-1996 and compared with that from 1997-2000. Objective: To estimate the incidence and prevalence as well as the tendency to pharmacoresistance in patients registered at the National Institute of Respiratory Disease and to determine the geographical distribution and evaluate treatment efficiency at the health units. Material and methods: Used terms are defined: pharmacoresistance, multiresistance, treatment efficiency, relapse and retreatment. Information was revised on 1,705 tuberculosis patients is registered at the Clinical research Department of the National Institute of Respiratory Disease, of which 1,459 were pulmonary and 246 extrapulmonary. Of the pulmonary patients, 275 clinical charts were registered as relapses or retreatment corresponding to categories II and IV of the World Health Organization and results on drug sensitivity to sort them by year and federative entity. Results: Prevalence of pharmacoresistance during the period 1997-2000 was 15.8% higher than during the period 1994-1996 (13.0%). Discussion: Information gathered from the treatment history of patients reveals that pharmacoresistance is originated by medical error and deficient organization in the treatment of tuberculosis. Conclusions: The solution to abate pharmacoresistance in tuberculosis is that both authorities and health staff should assume their compromise at national level, on the one hand, to strengthen the Short Course Directly Observed Therapy or with Short Course Strictly Observed Therapy, which has had good results in treatment efficiency, and on the other, to stimulate State officials to organize and equip their administrative units (sanitary jurisdiction) making them able to comply with the activities of the Tuberculosis Control Program and those of general health.REFERENCES
