Aspectos epidemiológicos da tuberculose na população indígena Suruí, Amazônia, Brasil

Abstract

Tuberculosis persists as a serious public health problem in Brazil. Prevalence rates are alarming in certain social groups, including indigenous peoples. This article presents an epidemiological analysis of records for the Suruí Indians available at the Tuberculosis Control Program in the Municipality of Cacoal, Rondônia. The study includes a descriptive statistical analysis of cases reported from 1975 to 2002. There is evidence that the Suruí have an increased risk of acquiring and dying from tuberculosis as compared to other indigenous groups in Rondônia as well as non-Indians. The average incidence coefficient for tuberculosis in the Suruí was 2518.9 per 100,000 inhabitants in the period 1991-2002. It was observed that 45% of the cases were diagnosed in children < 15 years old. Over half of the cases (63.3%) were reported in men. Only 43.2% of the cases were confirmed by sputum microscopy. The use of PPD skin tests, histopathological exams or bacteriological culture were not reported throughout the period. Attention is called to the need for prevention and control measures specifically tailored to the reality of indigenous peoples.

Detection of Mycobacterium tuberculosis in sputum from Suruí Indian subjects, Brazilian Amazon

“…As it has been noted elsewhere, this village complex that maintains intense social exchange, not only concentrates nearly all TB cases identified in this survey (Basta et al 2006), but it also accounts for close to half of all prior cases reported among the Suruí (Basta et al 2004). Although at present this constitutes the largest Suruí village, concentrating circa 20% of the total population, further studies remain to be done in order to clarify MTB transmission patterns in this population.…”

“…The average incidence of TB among the Suruí between 1991 and 2002 was 2,518.9 per 100,000 inhabitants, almost 50 times higher than the regional average, with nearly half the cases diagnosed in children < 15 years old (Basta et al 2004).…”

“…Recent studies show that the incidence and case fatality rates for tuberculosis in the Brazilian Amazon may be over ten times higher among Indians than those observed among non-Indians living in the same region (Sousa et al 1997, Escobar et al 2001, Garnelo et al 2003, Basta et al 2004.…”

Perfil Epidemiológico da Tuberculose no Município de João Pessoa – PB, entre 2007 - 2010

“…(BASTA et al, 2004 Quanto à distribuição etária, a população mais acometida foi a adulta, com 1.475 ocorrências (80,6%). Apesar de que, em termos absolutos, a maioria dos casos ocorreu em indivíduos com idades entre 20 -29 anos (27,5%), a maior taxa de incidência ocorreu na faixa etária de 30 -39 anos (104,1/100 mil).…”

Padrões radiológicos da tuberculose pulmonar em indígenas Suruí de Rondônia, Amazônia

“…Embora, a forma pulmonar da doença tenha sido a mais freqüente, aproximadamente 25% dos indivíduos que iniciaram tratamento no período não foram radiografados. Além disso, o rendimento da baciloscopia foi baixo e apenas 40% dos casos foram confirmados com base no isolamento bacilo 4 .…”
