“…Recent studies carried out with the Suruí ethnical group in Rondônia, however, have indicated that there may be errors in the diagnostic classification of TB cases in indigenous children 16,17 . In the studies cited, the authors discuss that in approximately 1/3 of the cases registered in under 15 year-old individuals, treatments were initiated without the complete exploration of all diagnostic investigation possibilities.…”

With the intention of improve knowledge on the epidemiological situation of tuberculosis (TB) among vulnerable populations in Brazil, our objective was to analyze sociodemographic characteristics and operational indicators related to TB control, comparing indigenous and non-indigenous people, in Rondônia. We conducted a retrospective and descriptive epidemiological study of new TB cases reported between 1997, January 1st and 2006, December 31st. We excluded duplicate records and those for whom the results of treatment was change in diagnosis and transfer. TB cases were classified into two categories: indigenous and non-indigenous people and analysis was performed according to sex, age, origin (urban /rural), State of residence, clinical form, diagnostic tests, monitoring indicators and results of treatment. Altogether 4832 cases were reported, with 322 cases (6.7%) in indigenous people. There was a male predominance (ratios: 1.7 to 1.3 in non-indigenous and indigenous people). The majority of cases for indigenous people (82.6%) was in rural area and there was high concentration of cases (36.0%) in children < 15 years. The analysis of diagnostic tests showed a predominance of smear positive in non-indigenous (56.1%) and smear negative and smear not performed in indigenous people (31.7% and 35.4% respectively, P value=0.0001). There was difference in the monitoring in relation to smear of second month (6.1% positivity, P value = 0.0001) and exam at least one contact (69.6%, P value = 0.017) for non-indigenous. On the other hand, DOTS was more associated with indigenous people cases (23.6%, P value = 0.0001). Stands out the predominance of cure in both groups, with bigger concentration in indigenous people (90.4%, P value = 0.0001) and higher rate of noncompliance in non-indigenous (14.7%, P value = 0.0001). The approach showed useful for elucidate inequalities and has exceeded the usual analysis carried out surveillance on services that aim to delineate the epidemiological situation based only on rates or absolute values.

“…Aprofundando o debate, Basta et al 9 constataram incidência média de TB, no período 1991-2002, acima de 2.500/100.000 entre os indígenas da etnia Suruí. Outro estudo baseado na busca ativa de sintomáticos respiratórios revelou a presença de uma cepa de Mycobacterium tuberculosis resistente à rifampicina e à isoniazida, demonstrou o envolvimento de quatro diferentes tipos de micobactérias na transmissão da doença e detectou ainda a presença de micobactérias ambientais em 12,8% das amostras de escarro examinadas nas aldeias analisadas 16,17 .…”

This study analyzed the spatial and temporal distribution of crude and adjusted rates of incidence of tuberculosis (TB) between 1997 and 2006, identifying areas of greatest risk to the indigenous and non-indigenous population of Rondônia State, Brazil. An ecological study was conducted analyzing municipalities and Indian reserves, using the local empirical Bayesian method. The crude average rate of incidence of TB among the non-indigenous population was 35.6/100,000 inhabitants, while for the indigenous population it was 415.0/100,000. Rates greater than 600/100,000 were reported in the Karipuna, Sete de Setembro, Igarapé, Ribeirão and Karitiana reserves. We observed a greater number of cases in under 15 year-olds with little schooling in contrast to the situation in the non-indigenous population. After making adjustments, the rates in some Indian reserves exceeded 240/100,000 inhabitants, while in coinciding municipalities incidence was between the range of 61-120/100,000. The Bayesian method led to decreased overall heterogeneity in rates. Evidence suggests that the indigenous population is more vulnerable to contracting TB and highlighted areas that require further attention to ensure the adequate control of TB in Rondônia.

ObjectiveTo describe the radiological findings of pulmonary tuberculosis in indigenous patients from the city of Dourados, MS, Brazil, according to age and sex.Materials and MethodsChest radiographic images of 81 patients with pulmonary tuberculosis, acquired in the period from 2007 to 2010, were retrospectively analyzed by two radiologists in consensus for the presence or absence of changes. The findings in abnormal radiographs were classified according to the changes observed and they were correlated to age and sex. The data were submitted to statistical analysis.ResultsThe individuals’ ages ranged from 1 to 97 years (mean: 36 years). Heterogeneous consolidations, nodules, pleural involvement and cavities were the most frequent imaging findings. Most patients (55/81 or 67.9%) were male, and upper lung and right lung were the most affected regions. Fibrosis, heterogeneous consolidations and involvement of the left lung apex were significantly more frequent in males (p < 0.05). Presence of a single type of finding at radiography was most frequent in children (p < 0.05).ConclusionBased on the hypothesis that indigenous patients represent a population without genetically determined resistance to tuberculosis, the present study may enhance the knowledge about how the pulmonary form of this disease manifests in susceptible individuals.
