Evaluation of the Drug-Resistant Tuberculosis Surveillance System, Brazil, 2013-2017. / Avaliação do Sistema de Vigilância da Tuberculose Drogarresistente, Brasil, 2013-2017.

OBJECTIVE: to evaluate the Brazilian Drug-Resistant Tuberculosis Surveillance System (DRTB-SS). METHODS: this was an evaluative study, following Centers for Disease Control and Prevention guidelines, using national data from the Special Tuberculosis Treatment Information System (SITETB), and the Notifiable Diseases Information System (SINAN), from 2013 to 2017. RESULTS: average data completeness was 95% (schooling [89.1%; 5,417/6,078], nationality [94.7%; 5,754/6,078], race/skin color [99.1%; 6,023/6,078], type of resistance [98.6%; 5,995/6,078], clinical form [100%; 6,078/6,078], and HIV test [87%; 5,289/6,078]); average proportion of cases with sputum cultures performed was 65.7% (culture 1 [94.8%; 5,764/6,078], culture 2 [69.8%; 4,241/6,078], culture 3 [54.7%, 3,324/6,078], and culture 4 [43.6%; 2,652/6,078]); DRTB-SS reported 52% (1,197/2,300) of multi-resistant cases estimated by the World Health Organization in 2015, 41.3% (990/2,400) in 2016, and 45.8% (1,100/2,400) in 2017. CONCLUSION: low DRTB-SS sensitivity suggests the need for improved access to DRTB diagnosis.

Febre maculosa na Região Metropolitana de Belo Horizonte, Minas Gerais - Brasil: Descrição dos casos e dos ambientes prováveis de infecção, 2017 / Spotted fever in the Metropolitan Region of Belo Horizonte, Minas Gerais - Brazil: Description of cases and probable environments of infection, 2017

Objetivo: investigar os casos de febre maculosa, verificar os aspectos relacionados à assistência à saúde e caracterizar o perfil epidemiológico desses e do ambiente de infecção. Métodos: estudo descritivo dos casos confirmados de FM entre janeiro e novembro de 2017. Foi elaborado um formulário semiestruturado para coleta dos dados. Para as análises epidemiológicas, foram utilizados os programas EpiInfoTM 7 e Qgis® 2.18.1. Foram calculadas frequências, medidas de tendência central, dispersão e indicadores de oportunidade de assistência. Nos ambientes prováveis de infecção, foram realizadas coletas de carrapatos que foram identificados e submetidos à pesquisa de Rickettsia do grupo da FM. Resultados: foram confirmados 15 casos de FM; desses, a maioria foi do sexo masculino (93%) com média de 42 anos de idade; 10 evoluíram para óbito. Todos apresentaram febre, 13(87%) cefaleia e 12(80%) mialgia. Apresentaram mediana e média de evolução para óbito pela doença de 6 dias (1 a 9), oportunidades de hospitalização, tratamento, diagnóstico e notificação de 4,5(0 a 8); 7(0 a 26); 9(DP±6) e 33(DP±45) dias, respectivamente. Para assistência à saúde, 14(93%) casos procuraram atendimento mais de duas vezes, com tempo de internação de 4,5 dias (0 a 8 dias). O hospital foi o serviço procurado, exclusivamente, no quarto atendimento. Dengue e FM foram as hipóteses diagnósticas mais frequentes. Foram coletados 250 espécimes de carrapatos em quatro municípios, sendo em um município identificado Amblyomma sculptum naturalmente infectados. Conclusões: foram assinaladas condições assistenciais pouco sensíveis à ocorrência da FM, o que, provavelmente, colaborou para ocorrência de óbitos, além da necessidade de sensibilização de equipes de saúde e vigilância quanto à ocorrência da FM na região.

Objective: investigate the cases of spotted fever, verify aspects related to health care and characterize the epidemiological profile of these and of the environment of infection. Methods: A descriptive study of confirmed cases of SF between January and November 2017. A semi-structured form for data collection was developed. EpiInfoTM 7 and Qgis® 2.18.1. Frequencies, measures of central tendency, dispersion and indicators of opportunity of assistance were calculated. In the probable environments of infection ticks were collected, identified and submitted to Rickettsia research of the SF group. Results: Fifteen SF cases were confirmed; of these, the majority was male (93%) and averaged 42 years old; 10 evolved to death. All presented fever, 13 (87%) headache and 12 (80%) myalgia. They presented an average of evolution to death by SF of 6 days (1 to 9), opportunities for hospitalization, treatment, diagnosis and notification of 4.5(0 to 8); 7(0 to 26); 9(DP± 6) and 33(DP± 45) days respectively. For health care, 14(93%) cases sought care more than twice and were hospitalized for 4.5-days (0 to 8 days). The hospital was the only service exclusively sought in the fourth service. Dengue and SF were the most frequent diagnostic hypotheses. A total of 250 specimens of ticks were collected in four counties, and in one municipality Amblyomma sculptum was identified as naturally infected. Conclusions: It was pointed out that assistance conditions were not very sensitive to the occurrence of SF which probably contributed to the instance of deaths as well as the need for sensitization of health and surveillance teams regarding the appearance of SF in the region.

Spatial and temporal trends of visceral leishmaniasis by mesoregion in a southeastern state of Brazil, 2002-2013.

BACKGROUND: Visceral leishmaniasis (VL) is expanding in Brazil and in other South American countries, a process that has been associated with the urbanization of the disease. This study analyzes the spatial and temporal distribution of VL in the Brazilian state of Minas Gerais and identifies the areas with higher risks of transmission. METHODOLOGY: An ecological study with spatial and time series analyzes of new confirmed cases of VL notified to the Brazilian Notifiable Disease Information System between 2002 and 2013, considering the 12 mesoregions of Minas Gerais. Two complementary methodologies were used: thematic maps of incidence and Poisson (log-linear) generalized linear model. Thematic maps using crude and smoothed cumulative incidences were generated for four trienniums. Poisson Regression measured the variation of the average number of cases from one year to the following, for each mesoregion. PRINCIPAL FINDINGS: The 5,778 cases analyzed revealed a heterogeneous spatial and temporal distribution of VL in Minas Gerais. Six mesoregions (Central Mineira, Jequitinhonha, Metropolitan area of Belo Horizonte, Northwest of Minas, North of Minas, and Vale do Rio Doce) were responsible for the expansion and maintenance of VL, with incidence rates as high as 26/100,000 inhabitants. The Vale do Rio Doce and Jequitinhonha mesoregions showed a considerable increase in the incidence rates in the last period studied. The other six mesoregions reported only sporadic cases and presented low and unsteady incidence rates, reaching a maximum of 1.2/100,000 inhabitants. CONCLUSIONS/SIGNIFICANCE: The results contribute to further the current understanding about the expansion of VL in Minas Gerais and may help guide actions for disease control.

Descentralização e expansão dos tratamentos de leishmaniose visceral (LV) com anfotericina B lipossomal em Minas Gerais, 2008-2012 / Decentralization and expansion of visceral leishmaniasis (VL) treatment with liposomal amphotericin B in Minas Gerais, 2008-2012

Descrever a descentralização e a expansão dos tratamentos da leishmaniose visceral (LV) com anfotericina B lipossomal em Minas Gerais, no período entre 2008 e 2012. Estudo descritivo que avaliou as fichas utilizadas para solicitar o tratamento com o medicamento e casos de LV no Sistema Nacional de Agravos de Notificação (SINAN). Foram avaliadas 646 solicitações de tratamento realizadas por 29 municípios, permitindo o tratamento de 577 pacientes, residentes em 97 municípios. A proporção de pacientes com LV tratados com anfotericina B lipossomal no Estado foi de 22,4%. As principais referências para o tratamento dos pacientes com LV foram as regiões Centro (URS Belo Horizonte) e Norte (URS Montes Claros). A descentralização e a expansão dos tratamentos refletem uma resposta positiva das equipes de assistência e vigilância do Estado e poderão contribuir favoravelmente para a evolução clínica dos casos de LV.

To describe the decentralization and expansion of VL treatment with liposomal amphotericin B in Minas Gerais between 2008 to 2012. This descriptive study evaluated forms used to request drug treatment and VL cases from the Reportable Disease Information System (SINAN). Were evaluated 646 treatment requests performed by 29 municipalities, allowing treatment of 577 patients residing in 97 municipalities. Proportion of patients with VL treated with lipossomal amphotericin B in the State was 22.4%. The main references for treatment of VL patients were Central (URS Belo Horizonte) and North (URS Montes Claros) regions. Decentralization and expansion of treatments reflect a positive response from assistance and surveillance teams of the State and may contribute favorably to clinical outcome of VL cases. Keywords: Visceral leishmaniasis, amphotericin B, decentralization.
