Clinical-epidemiological characteristics and temporal trend of new cases of grade 2 disability leprosy in the state of Maranhão, Brazil, 2011- 2020.

MAIN RESULTS: Out of 2,147 grade 2 disability leprosy cases, the majority were male, of mixed race/skin color, multibacillary and borderline. The São Luís regional health unit showed a falling trend. IMPLICATIONS FOR SERVICES: The results can guide strategies for the leprosy control program in the state, aiming at new approaches towards early diagnosis, treatment and prevention of disabilities. PERSPECTIVES: Further studies are needed, such as spatial distribution of cases and detection rates of leprosy in children under 15 years of age, in order to gain a better understanding of the epidemiological profile of leprosy in Maranhão. OBJECTIVE: to describe the clinical and epidemiological characteristics of new cases of grade 2 disability leprosy and to analyze its trend in the state of Maranhão, from 2011 to 2020. METHODS: this was a descriptive cross-sectional and ecological time-series study, using data from the Notifiable Health Conditions Information System. A descriptive analysis of the event was carried out according to the sociodemographic and clinical-laboratory characteristics of the cases. The temporal trend of event incidence was analyzed using Prais-Winsten regression. RESULTS: of the 2,147 cases, 71.5% were male, 48.9% had up to 8 years of schooling, 66.5% were of mixed race/color, 95.5% had the multibacillary form, 58.8% were borderline, 32.3% had negative bacilloscopy at diagnosis. There was a stationary trend in the state and a falling trend in the São Luís Health Region (annual percentage change = -64.4%; 95% confidence interval: -73.7;-51.9). CONCLUSION: incidence trend was stable in the state of Maranhão and falling in São Luís.

Leprosy prevalence spatial distribution and trend in a health region in Northeast Brazil, 2008-2017: an ecological study.

MAIN RESULTS: A total of 4,029 leprosy cases were notified. Mean prevalence varied between 2.0 and 11.5 cases/10,000 inhab. Spatial distribution of the cases was heterogeneous and there was a falling prevalence trend over the years studied. IMPLICATIONS FOR SERVICES: These findings point to the need to strengthen active tracing strategies and expand health actions and services targeting leprosy, with the aim of increasing detection and early treatment of cases. PERSPECTIVES: It is important to carry out epidemiological investigations on the spatial distribution and prevalence of leprosy in other health regions in the state, in order to identify other areas with greater vulnerability to leprosy. OBJECTIVE: to analyse the spatial distribution and trend of leprosy in municipalities of a health region in a Northeast Brazilian state. METHODS: this was an ecological time-series study based on compulsory notification of leprosy cases by the municipalities covered by the Imperatriz-MA Regional Health Management Unit, between 2008 and 2017; prevalence and mean prevalence for the period were calculated; spatial analysis of the area was carried out and maps were generated using ArcGis 10.5. Prais-Winsten regression was used for trend analysis. RESULT: 4,029 cases of the disease were identified, and average prevalence ranged from 2.0 to 11.5 cases/10,000 inhabitants-year. The overall trend was downward. Governador Edson Lobão had the highest prevalence, 11.5 cases/10,000 inhabitants, and Lajeado Novo had the lowest prevalence, 2.0 cases/10,000 inhabitants. CONCLUSION: spatial distribution of leprosy cases was heterogeneous in the municipalities studied and prevalence had a falling trend.

Factors associated with multibacillary leprosy in a region of northeastern Brazil.

INTRODUCTION: The analysis of factors associated with multibacillary leprosy is important for the development of strategies to mitigate the disease, which persists as a public health problem in Brazil and the world. The objective of this study was to verify the associations between sociodemographic and clinical-epidemiological variables and multibacillary leprosy in the state of northeastern Brazil. METHODOLOGY: This is a cross-sectional, analytical, and retrospective study, with a quantitative approach, carried out in 16 municipalities in the southwest of Maranhão State, northeastern Brazil. All cases of leprosy reported between January 2008 and December 2017 were considered. Sociodemographic and clinical-epidemiological variables were analyzed using descriptive statistics. The identification of the risk factors associated with multibacillary leprosy was conducted using Poisson regression models. The prevalence ratios and respective 95% confidence intervals were estimated using regression coefficients at a 5% significance level. RESULTS: A total of 3,903 leprosy cases were analyzed. Individuals older than 15 years, males, with less than 8 years of education, with level I, II, or "not evaluated" disability, and with type 1 or 2 or both reactional states were more likely to have multibacillary leprosy. Therefore, these characteristics may be considered risk factors. No protective factors were identified. CONCLUSIONS: The investigation revealed important associations between risk factors and multibacillary leprosy. The findings can be considered during the creation of strategies to control and combat the disease.

Leprosy in the context of the Family Health Strategy in an endemic scenario in Maranhão: prevalence and associated factors. / Hanseníase no contexto da Estratégia Saúde da Família em cenário endêmico do Maranhão: prevalência e fatores associados.

This study aimed to describe the prevalence of leprosy and verify the factors associated with multibacillary clinical types in a Family Health Strategy priority setting to control and monitor the disease in northeastern Brazil. This cross-sectional study used data from the Notifiable Diseases Information System related to leprosy cases notified in Imperatriz, Maranhão, between 2008 and 2017. The prevalence was determined yearly and for the period. Poisson regression models with a significance level of 5% were employed to associate the variables and the multibacillary clinical types. Most of the 2,476 leprosy cases analyzed referred to multibacillary clinical types. The prevalence ranged from 7.8 and 15.6/10,000 inhabitants, with high and very high endemicity levels. The variables male, age groups between 30 and 59 years and ≥60 years, schooling <8 years, level 2 physical disability, types 1 and 2 reactive episodes, and urban residence area showed significant associations (p≤0.05) with multibacillary clinical types. Such findings can serve as a basis for elaborating and implementing leprosy control and surveillance measures, gearing actions to the most vulnerable groups, and becoming more effective.

A prevalência variou entre 15,6 e 7,8/10 mil habitantes, encontrando-se níveis alto e muito alto de endemicidade. As variáveis sexo masculino, faixas etárias entre 30 e 59 anos e ≥60 anos, escolaridade <8 anos, grau 2 de incapacidade física, episódio reacional tipos 1 e 2 e zona de residência urbana apresentaram associações significativas (p≤0,05) com as formas clínicas multibacilares. Tais achados podem servir de base para elaboração e implementação de medidas de controle e vigilância da hanseníase, direcionando as ações para os grupos mais vulneráveis e tornando-se mais efetivas.

Spatial-temporal analysis of leprosy in a priority Brazilian northeast municipality for disease control.

OBJECTIVES: to analyze the spatial-temporal distribution of leprosy in a priority municipality for leprosy control. METHODS: ecological study, conducted in a city in the Northeast of Brazil, whose analysis units were census sectors. The study used compulsory notification data for cases registered between 2008 and 2017. TerraView software and the Batch Geocode tool was used for geocoding. The detection of spatial-temporal agglomerations of high relative risks was done by scanning statistics. RESULTS: the spatial-temporal distribution of cases was heterogeneous, creating four agglomerations of high relative risks in the urban area of the municipality between the years 2008 and 2012; and annual prevalence rates classified from high to hyperendemic. CONCLUSIONS: areas of higher risk and concentration of the disease in space-time were linked to the characteristics of high population density and social vulnerability of these spaces, raising the prioritization of health professionals' actions, systems, and services for control, and monitoring the disease.

Estratégias de controle e vigilância de contatos de hanseníase: revisão integrativa / Strategies for control and surveillance of leprosy contacts: integrative review

RESUMO A pesquisa objetivou analisar as evidências científicas disponíveis sobre controle e vigilância epidemiológica de contatos de hanseníase. Trata-se de uma revisão integrativa norteada pela pergunta: qual a produção científica sobre controle e vigilância epidemiológica de contatos de hanseníase? Incluíram-se estudos primários, publicados em inglês, português ou espanhol nas bases de dados PubMed, Lilacs e Cinahl, entre 2008 e 2018, disponíveis na íntegra. A amostra foi composta por 19 estudos. Identificaram-se três categorias temáticas: fatores de risco para infecção e adoecimento entre os contatos de hanseníase, vigilância ativa de contatos de hanseníase e novas estratégias de controle e vigilância de contatos de hanseníase. Os resultados mostraram estudos voltados à prevenção e controle da hanseníase entre os contatos, entretanto, as evidências apontam novas estratégias que podem ser incorporadas à prática clínica visando à eliminação da hanseníase como problema de saúde pública no País.

ABSTRACT The objective of this research was to analyze the available scientific evidence on control and epidemiological surveillance of leprosy contacts. This is an integrative review guided by the question: what is the scientific production on control and epidemiological surveillance of leprosy contacts? Primary studies published in English, Portuguese, or Spanish in the PubMed, Lilacs, and Cinahl databases from 2008 to 2018, available in full, were included. The sample consisted of 19 studies. Three thematic categories were identified: risk factors for infection and illness among leprosy contacts, active surveillance of leprosy contacts, and new strategies for control and surveillance of leprosy contacts. The results showed studies focused on the prevention and control of leprosy among contacts, however, the evidence points to new strategies that may be incorporated into clinical practice aiming at the elimination of leprosy as a public health problem in the Country.
