Enfrentamento da hanseníase em tempos de COVID-19: uma experiência exitosa de implantação de um sistema de rastreamento em área endêmica do Nordeste / Coping with leprosy in times of COVID-19: a successful experience of implementing a tracking system in an endemic area in the Northeast / Enfrentando la lepra en tiempos de COVID-19: una experiencia exitosa de implementación de un sistema de rastreo en un área endémica del Nordeste

Introdução: A COVID-19 (coronavirus disease 2019) trouxe inúmeros desafios e sobrecarga ao Sistema Único de Saúde (SUS), gerando dificuldades no enfrentamento das outras enfermidades endêmicas e negligenciadas no território brasileiro, entre elas a hanseníase. Objetivo: Relatar a experiência de enfrentamento da prevalência oculta de hanseníase por uma equipe de atenção primária à saúde do interior do estado de Sergipe durante a pandemia de COVID-19. Métodos: O projeto foi desenvolvido entre os meses de setembro de 2020 e janeiro de 2021 e caracterizou-se pela oferta de exame dermatológico aos indivíduos que buscaram atendimento na unidade de saúde do bairro Cidade Nova, em Estância, Sergipe. Confirmado o diagnóstico de hanseníase, foi introduzido o tratamento com esquema de poliquimioterapia da Organização Mundial da Saúde (PQT-OMS) e os contatos foram examinados, respeitando-se as medidas sanitárias de prevenção à contaminação pela COVID-19. Resultados: No período analisado, foram avaliados 235 indivíduos, sendo feitos seis diagnósticos clínicos de hanseníase (2,5%), entre os quais um em menor de 15 anos de idade. No município, durante todo o ano de 2020, registrou-se o total de nove casos novos de hanseníase. Sem o projeto, o coeficiente de detecção de casos novos de hanseníase no município seria de 4,3/100 mil habitantes e, com o projeto, esse coeficiente foi três vezes superior (12,9/100 mil habitantes). Conclusão: A oferta de exame dermatoneurológico durante consultas médicas de rotina em áreas vulneráveis permitiu evidenciar a prevalência oculta de hanseníase no bairro Cidade Nova, Estância. Além disso, ações dessa natureza permitem o diagnóstico precoce, evitando-se a evolução para incapacidades físicas.

Introduction: COVID-19 (coronavirus disease 2019) has brought numerous challenges and burdens on the Unified Health System (SUS, acronym in Portuguese), creating difficulties for the facing of other endemic diseases in the Brazilian territory, such as leprosy. Objective: To report an experience of coping with the hidden prevalence of leprosy by a primary health care team in the countryside of the state of Sergipe during the COVID-19 pandemic. Methods: The project was developed from September 2020 to January 2021 and was characterized for offering a dermatological examination to individuals seeking care at the health unit in the Cidade Nova neighborhood, Estância, Sergipe. For confirmed cases, treatment was instituted and household contacts were examined, respecting the measures to prevent contamination by COVID-19. Results: In the analyzed period, 235 individuals were evaluated, with six diagnoses of leprosy (2.5%), one under the age of 15. In 2020, the municipality registered nine total cases. Without the project, the detection rate of new leprosy cases in the municipality would have been 4.3/100,000 inhabitants and, with the project, this coefficient was three times higher (12.9/100,000 inhabitants). Conclusion: The offer of dermato-neurological exams during routine medical appointments made it possible to show the hidden prevalence of leprosy in the neighborhood of Cidade Nova, Estância. In addition, actions of this nature allow early diagnosis, preventing the occurrence of physical disabilities.

Conclusión: La oferta de exámenes dermatoneurológicos durante las consultas médicas de rutina permitió mostrar la prevalencia oculta de la lepra en el barrio Cidade Nova, Estância. Además, acciones de esta naturaleza permiten un diagnóstico precoz, evitando la aparición de discapacidades físicas.

Pure neural leprosy or amyloid neuropathy? Systematic review and clinical case report.

OBJECTIVE: To review the literature and to report a clinical case with initial suspicion of pure neural leprosy and final diagnosis of amyloid neuropathy. METHODS: The study was conducted in two stages. In stage one, a systematic literature review was carried out, with searches performed in the PubMed, Medline, and Lilacs databases, as well as in the leprosy sectoral library of the Virtual Health Library, using the following descriptors: neuritic leprosy, pure neural leprosy, primary neural leprosy, pure neuritic leprosy, amyloid polyneuropathy, amyloid neuropathies, and amyloid polyneuropathy. The search was carried out on May 28, 2020. Clinical trials, cohort studies, cross-sectional studies, clinical cases, and case studies published in Portuguese, English or Spanish between 2010 and 2020 were included. Stage two reports a case with initial suspicion of pure neural leprosy. Laboratory tests, electroneuromyography, ultrasound, and biopsy of the sural nerve were requested. RESULTS: Twenty-three scientific texts were included. No publications were found that contained both topics together. The challenging diagnosis of pure neural leprosy and the possibility of using auxiliary resources in diagnosis were the most emphasized themes in the studies. In the clinical case, the patient's electroneuromyography showed sensitive and motor polyneuropathy of the lower limbs, which was predominantly sensory and axonal, symmetrical, of moderate intensity, and the mixed type (axonal-demyelinating). Ultrasonography of the sural nerve revealed changes in the contour of the deep fibular nerves; biopsy of the sural nerve showed an accumulation of amorphous eosinophilic material in the nerve path, and Congo red stain showed apple-green birefringence of the deposit under polarized light. The final diagnosis was amyloid neuropathy. CONCLUSIONS: The final clinical diagnosis was amyloid neuropathy. The diagnosis of pure neural leprosy in endemic areas in Brasil is still a challenge for the health system.

Epidemiological, neurofunctional profile and prevalence of factors associated with the occurrence of physical disabilities due to leprosy in a reference center in Northeast Brasil: a sectional study.

OBJECTIVE: To describe the epidemiological and neurofunctional profile, as well as the prevalence of factors associated with the occurrence of physical disabilities due to leprosy in a reference center in Northeast Brasil. METHODS: A cross-sectional study including 50 leprosy patients diagnosed in Juazeiro-Bahia. Variables analyzed: sex, age, history of leprosy in the family, time to diagnosis, clinical form, operational classification, degree of disability, eyes-hand-foot score, peripheral nerve function, muscle strength and sensitivity. Descriptive statistics and inferential statistics (χ² test or Fisher's exact, Poisson regression with robust estimation and prevalence reason were used. Significance of 5%). RESULTS: An equal distribution was found between men and women of economically active age and low education; multibacillary forms in men (64%) and paucibacillary forms in women (60%). 78% of individuals had some degree of disability and 64% had a compromised ulnar nerve. Plantar sensitivity was decreased in 66% of patients. The predictors of disability were: age ≥45 years (PR 1.44; p=0.005), no education (PR 1.21; p=0.013) and OMP score ≥6 (PR 1.29; p<0.001). CONCLUSION: The findings show the importance of monitoring neural functions and developing measures that allow early diagnosis, the opportune method and the prevention of disabilities, especially in the male population.

Leprosy in Brazil in the 21st century: analysis of epidemiological and operational indicators using inflection point regression

Abstract The objective of this study was to analyze the trend of epidemiological and operational indicators of leprosy in Brazil, from 2001 to 2017. This was a time series study involving nine indicators. The inflection point regression model was used. Decreasing trends were observed for the following: general detection (−4.8%), children under 15 (−3.7%), prevalence (−7.0%), and grade 2/million inhabitants (−3.5%). The proportion of individuals with grade 2 disability showed an upward trend (2.0%) from 2001 as well as contacts examined from 2003 (5.0%). The proportions of cure and of individuals with a degree of disability assessed at the time of the diagnosis and the cure showed a stationary behavior. Although advances are noted, there are still challenges to be overcome.

Epidemiological, temporal and spatial dynamics of leprosy in a municipality in northeastern Brazil (2008-2017): an ecological study.

INTRODUCTION: Leprosy is a chronic infectious disease caused by Mycobacterium leprae.This study aimed to analyze the epidemiological, temporal, and spatial dynamics ofleprosy in a municipality in northeastern Brazil. METHODS: This is an ecological study on new leprosy cases in the population of Arapiraca (Alagoas, Northeast Region, Brazil), from 2008 to 2017. Data extracted from a national database were analyzed forepidemiological indicators, factors associated with physical disabilities, and spatialanalysis in the neighborhoods of Arapiraca. RESULTS: A total of 292 new cases of leprosy were recorded, particularly occurring among the following groups: women, the age group of 46-59 years, brown-skinned individuals, people with less than eight years of schooling, and urban residents; the new cases were also predominantly the tuberculoid form and were of the paucibacillary classification of the disease. Almost 1/3 of the people had some degree of physical disability, which was mainly associated with the group 60 years of age and older, black ethnicity, and the multibacillary clinical form of leprosy. The joinpoint regression showed a stationary temporal behavior of indicators. There was a heterogeneous spatial distribution with active transmission areas, especially in the neighborhoods Primavera, Baixão, Ouro Preto, and downtown. CONCLUSIONS: The epidemiological indicators revealed complexity in the process of leprosy development. These spatial and temporal studies are relevant to help in the planning, monitoring, and guidance of interventions in the municipality. The spatial analysis showed heterogeneous distribution in the analyzed neighborhoods.

[Spatial modeling of leprosy in the state of Bahia, Brazil, (2001-2015) and social determinants of health]. / Modelagem espacial da hanseníase no estado da Bahia, Brasil, (2001-2015) e determinantes sociais da saúde.

This work analyzes the spatial distribution of leprosy in Bahia and associated social determinants. It is an ecological study, with leprosy data from 2001-2015. Three epidemiological indicators were selected: coefficient of detection in the general population and in children under 15 and the rate of new cases with grade II physical disability. These indicators were flattened by the Local Empirical Bayesian Model and Global and Local Moran statistics were applied. The independent variables were selected from the IBGE-2010 Census. Multivariate regressions were employed, followed by spatial regression. Leprosy exhibited a heterogeneous distribution in the state, with concentration in the north-west axis and the south region. For the general detection coefficient, five variables composed the final model: demographic density, urban population proportion, per capita income, proportion of extremely poor and households with over three people per dormitory. The illiteracy proportion made up the final model for the grade II rate of physical disability. No determinants of the occurrence of the disease were identified in children under 15. The modeling used contributed to demonstrate the spatial heterogeneity and social determinants of the disease in Bahia, revealing the complexity of the problem.

O trabalho analisa a distribuição espacial da hanseníase na Bahia e os determinantes sociais relacionados. Estudo ecológico com dados de hanseníase do período 2001-2015. Três indicadores epidemiológicos foram selecionados: coeficiente de detecção na população geral e em menores de 15 anos e a taxa de casos novos com grau II de incapacidade. Os indicadores foram suavizados pelo Modelo Bayesiano Empírico Local e aplicou-se estatística de Moran Global e Local. As variáveis independentes foram selecionadas a partir do Censo IBGE-2010. Regressões multivariadas foram empregadas, seguidas de regressão espacial. Observou-se distribuição heterogênea no estado, com concentração no eixo norte-oeste e região sul. Para o coeficiente de detecção geral, cinco variáveis compuseram o modelo: densidade demográfica, proporção da população urbana, renda per capita, proporção de extremamente pobres e domicílios com mais de três pessoas por dormitório. A proporção de analfabetismo compôs o modelo final para a taxa de grau II de incapacidade física. Não foram identificados determinantes da ocorrência da doença em menores de 15 anos. A modelagem utilizada contribuiu para demonstrar a heterogeneidade espacial e os determinantes sociais da doença na Bahia, colocando em evidência a complexidade do problema.

Epidemiological monitoring of leprosy indicators in Sergipe (2001-2015): segmented regression analysis.

This study analyzed the trend of leprosy indicators in Sergipe, between 2001 and 2015. It was a time series study that analyzed the trend for general detection coefficient, children under 15 years of age, and new cases with grade 2 disability. The joinpoint model was used. Two (2.6%) municipalities had an increasing trend in general detection coefficient, five (6.6%) had an increasing trend in detection rate in children under 15, and 19 (25.3%) had an increasing trend in detection coefficient of new leprosy cases with grade 2 disability. The findings suggest maintenance of the chain of transmission.

Leprosy and social deprivation: Definition of priority areas in an endemic state Northeastern Brazil. / Hanseníase e carência social: definição de áreas prioritárias em estado endêmico do Nordeste brasileiro.

INTRODUCTION: Leprosy is a disease that reserves close relation with social and economic conditions. Brazil is the only country that has not yet reached the goal of eliminating the disease as a public health problem. OBJECTIVE: This study aimed to analyze social deprivation in the municipalities of Bahia and its relation with the detection of new cases of leprosy in the population. METHODS: It is an ecological study conducted in the state of Bahia, from 2001 to 2015. Variables analyzed: detection rate of new cases, social deprivation index (SDI) and Hansen's disease in children under 15 years of age. The SDI was built on four variables: socioeconomic performance index, per capita income, proportion of extremely poor, and household density. For spatial analysis, local empirical bayesian modeling and global and local Moran statistics were used. Statistical analysis used multivariate, spatial and logistic regression, odds ratio calculation and analysis of variance. RESULTS: Leprosy showed heterogeneous distribution in the state, with concentration in the north-west and south axis. 60.4% (n = 252) of the municipalities presented very low life conditions. An association was observed between living conditions and the detection of leprosy, with higher coefficients in the municipality group with better living conditions (p < 0.001). CONCLUSION: It was concluded that the worst conditions acted as an impediment to the diagnosis, while increasing the risk of illness. Good conditions have the opposite effect.

INTRODUÇÃO: A hanseníase é uma doença que guarda estreita relação com as condições sociais e econômicas. O Brasil é o único país que ainda não alcançou a meta de eliminação da doença como problema de saúde pública. OBJETIVO: Este trabalho teve como objetivo analisar a associação entre a carência social dos municípios baianos e a detecção de casos novos de hanseníase na população, como instrumento para a definição de áreas prioritárias para intervenção. METODOLOGIA: Trata-se de um estudo ecológico realizado no estado da Bahia, no período de 2001 a 2015. Variáveis analisadas: coeficiente de detecção casos novos, índice de carência social (ICS) e hanseníase em menores de 15 anos. O ICS foi construído com base em quatro variáveis: índice de performance socioeconômica, renda per capita, proporção de extremamente pobres e densidade domiciliar. Na análise espacial, foram utilizadas modelagem bayesiana empírica local e estatística de Moran global e local. Na análise estatística, foram empregados regressão multivariada, espacial e logística, cálculo do odds ratio e análise de variância. RESULTADOS: A hanseníase apresentou distribuição heterogênea no estado, com concentração no eixo norte-oeste e sul. Dos municípios, 60,4% (n = 252) apresentaram muito baixa condição de vida. Observou-se associação entre as condições de vida e a detecção da hanseníase, com maiores coeficientes no grupo de município com melhor condição de vida (p < 0,001). CONCLUSÃO: As piores condições atuaram como um impeditivo ao diagnóstico, ao mesmo tempo que ampliaram o risco de adoecimento. As boas condições possuem efeito inverso.

Leprosy in the elderly population of an endemic state in the Brazilian Northeast (2001-2017): epidemiological scenario

Abstract This ecological study aims to analyze both the tendency and the characteristics of leprosy in the elderly population in the state of Bahia, 2001-2017. The tendency was analyzed through joinpoint regression. Epidemiological variables were also included in the study. The average detection rate was 38.73/100,000, with prevalence of men (45.19/100,000). A downward trend occurred in both genders, from 2004, with a greater magnitude in women (annual percent change [APC] = −3.4%). Men presented higher proportions of the multibacillary forms and physical disabilities. The epidemiological scenario indicates the need of implementation of actions that stimulate early diagnosis and treatment of the elderly population.

Observou-se associação entre as condições de vida e a detecção da hanseníase, com maiores coeficientes no grupo de município com melhor condição de vida (p < 0,001). Conclusão: As piores condições atuaram como um impeditivo ao diagnóstico, ao mesmo tempo que ampliaram o risco de adoecimento. As boas condições possuem efeito inverso.

ABSTRACT: Introduction: Leprosy is a disease that reserves close relation with social and economic conditions. Brazil is the only country that has not yet reached the goal of eliminating the disease as a public health problem. Objective: This study aimed to analyze social deprivation in the municipalities of Bahia and its relation with the detection of new cases of leprosy in the population. Methods: It is an ecological study conducted in the state of Bahia, from 2001 to 2015. Variables analyzed: detection rate of new cases, social deprivation index (SDI) and Hansen's disease in children under 15 years of age. The SDI was built on four variables: socioeconomic performance index, per capita income, proportion of extremely poor, and household density. For spatial analysis, local empirical bayesian modeling and global and local Moran statistics were used. Statistical analysis used multivariate, spatial and logistic regression, odds ratio calculation and analysis of variance. Results: Leprosy showed heterogeneous distribution in the state, with concentration in the north-west and south axis. 60.4% (n = 252) of the municipalities presented very low life conditions. An association was observed between living conditions and the detection of leprosy, with higher coefficients in the municipality group with better living conditions (p < 0.001). Conclusion: It was concluded that the worst conditions acted as an impediment to the diagnosis, while increasing the risk of illness. Good conditions have the opposite effect.

Trend of leprosy detection rate in Brazil, 1990 to 2016.

The objective of this study was to describe the trend of detection of the disease in Brazil from 1990 to 2016. The joinpoint regression model was used. There was a significant trend of decreased detection in the country (average annual percent change -1.8%) and in the South (average annual percent change=-3.5%) and Southeast regions (average annual percent change=-4.5%). The Northeast (average annual percent change=0.2%), the Central-West (average annual percent change=-1.5%), and the North (average annual percent change=-2.6%) showed a stationary trend (p>0.05). Eleven states showed a decreasing trend. Alagoas (average annual percent change=2.1%) and Rio Grande do Norte (average annual percent change=1.4%) presented significant increase (p<0.001). The heterogeneous pattern of trend between regions and states shows that efforts are needed to eliminate the disease.
