Title in Portuguese
Tuberculose resistente nos indivíduos HIV positivos em cinco municípios da Baixada Santista - SP
Keywords in Portuguese

Tuberculose
Abstract in Portuguese
Desde o início dos anos 90 vários estudos relatam aumento do número de casos de Mycobacterium tuberculosis resistentes às drogas tuberculostáticas, inclusive nos países desenvolvidos, com alta prevalência entre os pacientes HIV+. Objetivos: avaliar a frequência de resistência, o perfil de sensibilidade do Mycobacterium tuberculosis às drogas e os fatores predisponentes à resistência entre os indivíduos HIV positivos nos municípios de Santos, São Vicente, Cubatão, Praia Grande e Guarujá. Métodos: Levantamento dos prontuários de 301 pacientes que apresentaram resultado de cultura positivo e teste de sensibilidade às drogas tuberculostáticas entre 1993 e 2003. Resultados: A resistência às drogas foi diagnosticada em 57 pacientes (18,9%) com a seguinte distribuição: 32 (10,6%) apresentaram TB multirresistente (resistência a pelo menos rifampicina e isoniazida); 4 (1,3%) casos apresentaram resistência a duas ou mais drogas e 21 (7%) monorresistência. A resistência adquirida foi observada em 70,1% dos casos. Não houve associação entre tuberculose resistente e as variáveis: alcoolismo, uso de drogas injetáveis, contagem de CD4+, falta de domicílio e uso de antiretrovirais. As variáveis estatisticamente associadas a TB resistente foram: tratamento anterior com tuberculostáticos, tempo de diagnóstico de HIV e hospitalização prévia. Em análise multivariada apenas tratamento anterior, ajustado por faixa etária, mostrou-se estatisticamente associado (OR=5,49: IC95% 2,60-11,60). Conclusões: A ocorrência de resistência em 18,9% dos casos e multirresistência em aproxidamamente 10% confirmam a relevância deste problema entre pacientes HIV + na Baixada Santista. Entre os fatores de risco analisados apenas tratamento anterior com tuberculostáticos esteve estatisticamente associado.

Abstract in English
Since the early 90's, several studies have reported an increase in the number of drug resistance Mycobacterium tuberculosis cases, even in developed countries, with high prevalence between HIV positive patients. Objective: to evaluate the sensitivity patterns of M. tuberculosis , the rate of resistance and its predisposing factors among HIV positive patients in Santos, São Vicente, Cubatão, Praia Grande e Guarujá. Methods: Review of the medical charts of 301 patients who had positive cultures for M. tuberculosis and sensitivity tests from 1993 to 2003. Results: resistance occurred in 57 patients (18,9%), with the following pattern: 32 (10,6%) exhibited multidrug-resistant tuberculosis (resistance to at least rifampicin and isoniazid); 4 (1,3%) cases exhibited resistance to two or more drugs and 21 (7%) exhibited resistant strains to a single drug. Acquired resistance was observed in 70,1% cases. Drug resistance tuberculosis wasn't associated with: alcohol abuse, injecting drug use, CD4+ lymphocytes count, homelessness and antiretroviral use. The variables statistically significantly associated with drug resistance were: previous tuberculosis treatment, duration of HIV diagnoses and previous hospitalization. In logistic regression analysis only previous tuberculosis treatment, adjusted by age, remained as independent risk factor (OR=5,49: IC95% 2,60-11,60). Conclusion: drug resistance to at least one drug in 18,9% and multidrug resistance in 10,6% of the cases point out the importance of this problem in HIV patients at Baixada Santista. Of the analyzed risk factors only previous tuberculosis treatment was statistically significantly associated.
