SALAZAR LEZAMA, MIGUEL ÁNGEL et al. RESULTADOS DE TRATAMIENTO DE TUBERCULOSIS RESISTENTE EN 91 PACIENTES DEL INSTITUTO NACIONAL DE ENFERMEDADES RESPIRATORIAS: 2001-2003. Rev. Inst. Nal. Enf. Resp. Mex. [online]. 2004, vol.17, n.1, pp.15-21. ISSN 0187-7585.

Background: Tuberculosis (TB) persists as a public health world-wide problem. The principal human concern is to cure, relieve the suffering and reduce the mortality caused by this disease. A serious problem is the increasing prevalence of multidrug-resistant tuberculosis which contributes to the failure to erradicate TB. This requires an approach based on political, social and economic responsibility focused on the patient for TB control. Methods: We analyzed ninety-one files of patients with multidrug-resistant tuberculosis that were referred to the Institute by health services of different states and Mexico City. The cases were classified according to the criteria established by the World Health Organization (WHO). Results: In Group 1, the success rate was 63%, in Group 2 was 100% and in Group 3 was 41.8%. In the three groups the rate of success was 49%. After analyzing data by state, the worst results were from Morelos with 0%, Puebla 25%, Mexico state 38% and Mexico City with 58% (7 of 12). The best results were from Veracruz with 77%, Guerrero 75% and Chiapas 71%. This makes evident that the distance from the reference center is not a risk factor for treatment failure. Conclusions: It is imperative to prevent new cases of multidrug-resistant tuberculosis by increasing the rate of cure and to reduce the dissemination of the disease by efficiently treating all new cases.
