Nutritional aspects of people affected by leprosy, between 2001 and 2014, in semi-arid Brazilian municipalities. / Aspectos nutricionais de pessoas acometidas por hanseníase, entre 2001 e 2014, em municípios do semiárido brasileiro.

The study aimed to characterize food insecurity, nutritional status, and eating habits of people affected by leprosy. This is a descriptive cross-sectional study based on a census population. We evaluated 276 cases, reported in the Notifiable Diseases Information System, between 2001 and 2014, in the municipalities of Vitória da Conquista and Tremedal, in the state of Bahia. Food insecurity was estimated according to the Brazilian Food Insecurity Scale. We collected weight and height measurements, meal frequency, and household, socioeconomic, psychosocial and clinical variables. The prevalence of food insecurity was 41.0% among the study population - 28.3% mild, 8.0% moderate and 4.7% severe. Overweight/obesity was estimated in 60.1% of the study participants, and excessive salt intake was reported by 8.6%. Beans and red meat were the most regularly consumed foods; there was low consumption of milk, raw and cooked vegetables, and fruits. This population presented high food insecurity prevalence, inadequate eating habits and nutritional status, reflecting nutritional vulnerability. The insertion of nutritional assistance in the leprosy control programmes is recommended, to improve health care.

Epidemiology and Spatiotemporal Patterns of Leprosy Detection in the State of Bahia, Brazilian Northeast Region, 2001⁻2014.

The detection of leprosy cases is distributed unequally in Brazil, with high-risk clusters mainly in the North and Northeast regions. Knowledge on epidemiology and spatiotemporal patterns of leprosy occurrence and late diagnosis in these areas is critical to improve control measures. We performed a study including all leprosy cases notified in the 417 municipalities of Bahia state, from 2001 to 2014. New case detection (overall and pediatric <15 years) and grade 2 disability (G2D) rates were calculated and stratified according to socio-demographic variables. Spatial analyses were performed to detect high-risk areas for occurrence and late diagnosis. A total of 40,060 new leprosy cases was reported in the period (mean = 2861 cases/year), 3296 (8.2%) in <15-year-olds, and 1921 (4.8%) with G2D. The new case detection rate was 20.41 cases/100,000 inhabitants (95% CI: 19.68⁻21.17). A higher risk was identified in older age groups (RR = 8.45, 95% CI: 7.08⁻10.09) and in residents living in the state capital (RR = 5.30, 95% CI: 4.13⁻6.79), in medium-sized cities (RR = 2.80; 95% CI: 2.50⁻3.13), and in the west (RR = 6.56, 95% CI: 5.13⁻8.39) and far south regions of the state (RR = 6.56, 95% CI: 5.13⁻8.39). A higher risk of G2D was associated with male gender (RR = 2.43, 95% CI: 2.20⁻2.67), older age (RR = 44.08, 95% CI: 33.21⁻58.51), Afro-Brazilian ethnicity (RR = 1.59; 95% CI: 1.37⁻1.85), living in medium-sized cities (RR = 2.60; 95% CI: 2.27⁻2.96) and residency in the north (RR = 5.02; 95% CI: 3.74⁻6.73) and far south (RR = 7.46; 95% CI: 5.58⁻9.98) regions. Heterogeneous space⁻time patterns of leprosy distribution were identified, indicating high endemicity, recent transmission, and late diagnosis. This heterogeneous distribution of the disease was observed throughout the study period. Leprosy remains a relevant public health problem in Bahia state. The disease has a focal distribution. We reinforce the importance of integrating surveillance, prevention and control actions in regions of higher risk of leprosy detection and late diagnosis, and in the most vulnerable populations.

Incapacidades físicas em pessoas que concluíram a poliquimioterapia para hanseníase em Vitória da Conquista, Bahia, Brasil / Physical disabilities after multidrug therapy for leprosy in Vitória da Conquista, Bahia State, Brazil

Objetivo: Estimar a prevalência de incapacidades físicas e fatores associados, em pessoas que concluíram a poliquimioterapia (PQT) para hanseníase. Métodos: Realizou-se estudo transversal (n=222) no município de Vitória da Conquista-Bahia-Brasil, incluindo casos de hanseníase notificados de 2001-2014. As incapacidades físicas foram avaliadas por meio de aplicação de instrumento e avaliação do grau de incapacidade (GI) e do escore olho-mão-pé (OMP). Resultados: A prevalência de incapacidades físicas foi de 64,8% (n=144), e de GI 2 foi de 17,1% (n=38). As incapacidades físicas associaram-se de forma significante com analfabetismo (RP = 1,27; IC 95% = 1,05­1,54), classificação operacional multibacilar (RP = 1,26; IC 95% = 1,01­1,57), ocorrência de episódios reacionais (RP =1,41; IC 95% = 1,14­1,74) e dor/espessamento neural (RP = 1,3; IC 95% = 1,02­1,64). Houve piora do GI em 34 (32,1%) dos casos, considerando o momento do diagnóstico à alta. Conclusões: As incapacidades físicas, inclusive as com deformidades, constituem um importante problema no contexto individual e coletivo dos casos que seguem no pós-alta da PQT. Ressalta-se a necessitando de maior monitoramento e cuidado longitudinal, no sentido de prevenir sequelas específicas da doença.

Objective: To estimate the prevalence of physical disabilities and associated factors in people who completed multidrug therapy for leprosy. Method: A cross-sectional study (n = 222) was carried out in the city of Vitória da Conquista-Bahia-Brazil, including cases of leprosy reported from 2001-2014. Physical disabilities were assessed through instrument application and assessment of the degree of disability (GI) and the eye-hand-foot score (EHF). Results: The prevalence of physical disabilities was 64,8% (n = 144), and GI 2 was 17,1% (n = 38). Physical disabilities were significantly associated with illiteracy (RP = 1,27; 95% CI = 1,05-1,54), multibacillary operational classification (RP = 1,26; 95% CI = 1,01 -1,57), reactional episodes (RP = 1,41; 95% CI = 1,14 ­ 1,74) and pain / neural thickening (RP = 1,3; 95% CI = 1,02-1,64 ). There was worsening of GI in 34 (32,1%) of the cases, considering the time of diagnosis at discharge. Conclusions: Physical disabilities, including those with deformities, constitute an important problem in the individual and collective context of the cases that follow in the post-discharge of MDT. The need for greater monitoring and longitudinal care, in order to prevent specific sequalae of the disease.

Resumo Introdução A hanseníase é uma condição negligenciada, com alta carga de morbimortalidade, especialmente em áreas mais desfavoráveis. O objetivo deste estudo foi analisar as tendências e os padrões espaço-temporais da mortalidade relacionada à hanseníase no estado da Bahia, 1999-2014. Objetivo Analisar tendências e padrões espaço-temporais da mortalidade relacionada à hanseníase no Estado da Bahia de 1999 a 2014. Método Estudo de base populacional com dados secundários de mortalidade. Incluíram-se todos os óbitos em que a hanseníase foi mencionada como causa de morte. Resultados Foram registrados 1.152.262 óbitos, dos quais a hanseníase foi identificada em 481 (0,04%) casos, resultando em coeficiente bruto médio anual de mortalidade de 0,21 óbito/100 mil habitantes (intervalo de confiança [IC] de 95%: 0,13-0,29). Hanseníase não especificada (87,73%, ou 422/481) e complicações da hanseníase (6,44%, ou 31/481) foram as formas clínicas mais comumente mencionadas. O risco de óbito relacionado à hanseníase foi maior entre os homens (risco relativo [RR]: 2,38; IC 95%: 0,19-0,46), em idosos (RR: 74,79; IC 95%: 9,57-582,20) e na região oeste do Estado (RR: 4,08; IC 95%: 2,33-7,15). A mortalidade apresentou tendência temporal de aumento significativo no período ( Average Annual Percentual Change [AAPC] 7,3; IC 95%: 4,5 a 10,3), assim como a mortalidade proporcional (AAPC 5,3; IC 95%: 2,2 a 8,3). Conclusões A hanseníase representa uma causa negligenciada de óbito no Estado da Bahia. Apresenta tendências espaço-temporais desiguais nas regiões de saúde, com riscos associados, principalmente, à população masculina e idosa.

Abstract Background Leprosy is a neglected condition with a high mortality burden, especially in poorer areas. The objective of this study was to analyze temporal trends and spatiotemporal patterns of mortality related to leprosy in the state of Bahia, 1999-2014. Objective To analyze the spatiotemporal trends and patterns of mortality associated with leprosy in the state of Bahia, Brazil, from 1999 to 2014. Method Population-based study utilizing secondary mortality data including all deaths, in which leprosy was mentioned, recorded in the state of Bahia from 1999 to 2014. Results From a total of 1,152,262 deaths, leprosy was identified in 481 (0.04%) cases, resulting in a mean annual gross mortality rate of 0.21 deaths/100,000 inhabitants (95% confidence interval [CI]: 0.13-0.29). Unspecified leprosy (87.73%; 422/481) and leprosy complications (6.44%; 31/484) were the most commonly reported clinical forms. Risk of death associated with leprosy was higher among men (relative risk [RR]: 2.38; 95% CI; 0.19-0.46), elderly (RR: 74.79; 95% CI; 9.57-582.20), and in the eastern region of the state (RR: 4.08; 95% CI; 2.33-7.15). Overall mortality rates showed a significant increase during the observation period (Average Annual Percentage Change [AAPC] 7.3, 95% CI; 4.5-10.3), as well as proportional mortality (AAPC 5.3; 95% CI; 2.2-8.3). Conclusions Leprosy is a neglected cause of death in the state of Bahia. The disease presents unequal regional spatiotemporal trends, with risks associated mainly in males and older age groups.

Leprosy and gender in Brazil: trends in an endemic area of the Northeast region, 2001-2014.

OBJECTIVE To analyze, stratifield by gender, trends of the new case leprosy detection rates in the general population and in children; of grade 2 disability, and of proportion of multibacillary cases, in the state of Bahia, Brazil from 2001 to 2014. METHODS A time series study based on leprosy data from the National Information System for Notifiable Diseases. The time trend analysis included Poisson regression models by infection points (Joinpoint) stratified by gender. RESULTS There was a total of 40,054 new leprosy cases with a downward trend of the overall detection rate (Average Annual Percent Change [AAPC = -0.4, 95%CI -2.8-1.9] and a non-significant increase in children under 15 years (AAPC = 0.2, 95%CI -3.9-4.5). The proportion of grade 2 disability among new cases increased significantly (AAPC = 4.0, 95%CI 1.3-6.8), as well as the proportion of multibacillary cases (AAPC = 2.2, 95%CI 0.1-4.3). Stratification by gender showed a downward trend of detection rates in females and no significant change in males; in females, there was a more pronounced upward trend of the proportion of multibacillary and grade 2 disability cases. CONCLUSIONS Leprosy is still highly endemic in the state of Bahia, with active transmission, late diagnosis, and a probable hidden endemic. There are different gender patterns, indicating the importance of early diagnosis and prompt treatment, specifically in males without neglecting the situation among females.

[Programmatic vulnerability in leprosy control: gender-related patterns in Bahia State, Brazil]. / Vulnerabilidade programática no controle da hanseníase: padrões na perspectiva de gênero no Estado da Bahia, Brasil.

The aim of this study was to analyze operational indicators and time trends in leprosy control from a gender perspective in Bahia State, Brazil, from 2001 to 2014. This was a time series study based on epidemiological data on leprosy from the Brazilian National System of Diseases of Notification, using joinpoint Poisson and polynomial regression. Of the 40,054 new cases of leprosy, 47.1% of the recorded contacts were not examined, with a significant upward trend, especially in women (average annual percentage change - AAPC = 5.6; 95%CI: 3.5; 7.7) when compared to men (AAPC = 3.0; 95%CI: 0.5; 5.6). The proportion of cure in the 2003-2014 cohort was 85%, with a downward trend, especially in men (AAPC = -0.5; 95%CI: -0.9; 0.0), compared to women (AAPC = -0.4; 95%CI: -0.7; -0.1). Treatment dropout rate was 5.5%, with a more significant downward trend in women (AAPC = -4.9; 95%CI: -8.7; -1.1) than in men (AAPC = -2.7; 95%CI: -4.4; -1.0). Relapse was recorded in 3.8% of all the entries during the same period; women showed a significant downward trend (AAPC = -2.2; 95%CI: -3.3; -1.0) and men a significant upward trend (AAPC = 4.9; 95%CI: 2.9; 6.8). Polynomial regression analysis was consistent with joinpoint regression. Leprosy in Bahia State shows operational indicators with significant magnitude and time trends, especially in the male population. Health services' insufficient performance in conducting contact surveillance and longitudinal care reveal various dimensions of vulnerability.

Dos 40.054 casos novos de hanseníase analisados, 47,1% dos contatos registrados não foram examinados, mas com tendência significativa de aumento, de forma mais acentuada entre as mulheres (variação percentual anual média - AAPC = 5,6; IC95%: 3,5; 7,7) em comparação aos homens (AAPC = 3,0; IC95%: 0,5; 5,6). A proporção de cura na coorte 2003-2014 foi de 85%, com tendência de redução mais acentuada nos homens (AAPC = -0,5; IC95%: -0,9; 0,0), comparados às mulheres (AAPC = -0,4; IC95% -0,7; -0,1). A proporção de casos em abandono de tratamento no período foi de 5,5%, com tendência de redução mais significativa entre mulheres (AAPC = -4,9; IC95%: -8,7; -1,1) do que em homens (AAPC = -2,7; IC95%: -4,4; -1,0). Recidiva foi verificada em 3,8% de todas as entradas do período; as mulheres apresentaram tendência de redução significativa (AAPC = -2,2; IC95%: -3,3; -1,0) e os homens, de crescimento significativo (AAPC = 4,9; IC95%: 2,9; 6,8). A análise por regressão polinomial foi consistente com a análise de joinpoints. A hanseníase no Estado da Bahia apresenta indicadores operacionais com magnitude e tendência temporal significativas, em especial entre a população masculina. O desempenho insuficiente dos serviços de saúde em realizar a vigilância de contatos e a longitudinalidade do cuidado revelam diferentes dimensões de vulnerabilidade.

ABSTRACT OBJECTIVE To analyze, stratifield by gender, trends of the new case leprosy detection rates in the general population and in children; of grade 2 disability, and of proportion of multibacillary cases, in the state of Bahia, Brazil from 2001 to 2014. METHODS A time series study based on leprosy data from the National Information System for Notifiable Diseases. The time trend analysis included Poisson regression models by infection points (Joinpoint) stratified by gender. RESULTS There was a total of 40,054 new leprosy cases with a downward trend of the overall detection rate (Average Annual Percent Change [AAPC = -0.4, 95%CI -2.8-1.9] and a non-significant increase in children under 15 years (AAPC = 0.2, 95%CI -3.9-4.5). The proportion of grade 2 disability among new cases increased significantly (AAPC = 4.0, 95%CI 1.3-6.8), as well as the proportion of multibacillary cases (AAPC = 2.2, 95%CI 0.1-4.3). Stratification by gender showed a downward trend of detection rates in females and no significant change in males; in females, there was a more pronounced upward trend of the proportion of multibacillary and grade 2 disability cases. CONCLUSIONS Leprosy is still highly endemic in the state of Bahia, with active transmission, late diagnosis, and a probable hidden endemic. There are different gender patterns, indicating the importance of early diagnosis and prompt treatment, specifically in males without neglecting the situation among females.

RESUMO OBJETIVO Analisar, segundo gênero, as tendências temporais dos coeficientes de detecção de casos novos de hanseníase na população geral e em crianças, do coeficiente de grau 2 de incapacidade física e da proporção de casos multibacilares no estado da Bahia, no período de 2001 a 2014. MÉTODOS Estudo de série temporal baseado em dados epidemiológicos relativos à hanseníase oriundos do Sistema de Informação de Agravos de Notificação. A análise de tendência temporal incluiu modelos de regressão de Poisson por pontos de inflexão (Joinpoint), considerando-se a dimensão de gênero. RESULTADOS Dos 40.054 casos notificados no período, verificou-se tendência de redução no coeficiente de detecção geral (Average Annual Percent Change [AAPC] = -0,4; IC95% -2,8-1,9) e aumento em menores de 15 anos sem significância estatística (AAPC = 0,2; IC95% -3,9-4,5). Para o coeficiente de detecção com grau 2 de incapacidade física, a tendência foi de aumento significativo (AAPC = 4,0; IC95% 1,3-6,8), assim como nos casos multibacilares (AAPC = 2,2; IC95% 0,1-4,3). A análise estratificada por gênero indicou tendência de redução dos coeficientes de detecção entre as mulheres e de manutenção entre os homens, sem significância estatística. Em relação ao coeficiente de detecção em menores de 15 anos, a tendência de redução é mais acentuada nas mulheres do que entre os homens. As mulheres apresentaram tendência mais acentuada de aumento na proporção de casos multibacilares e do coeficiente de detecção de grau 2 de incapacidade. CONCLUSÕES O estado da Bahia mantém alta endemicidade, transmissão ativa, diagnóstico tardio e provável endemia oculta de hanseníase. Há um padrão diferencial segundo gênero, tornando central o diagnóstico e tratamento oportuno com estratégias diferenciadas para os homens, sem desconsiderar a situação entre as mulheres.

Social determinants of leprosy in a hyperendemic State in North Brazil.

OBJECTIVE: To identify the socioeconomic, demographic, operational, and health service-related factors associated with the occurrence of leprosy in a hyperendemic State in North Brazil. METHODS: This is an ecological study based on secondary data from the Sistema de Informações de Agravos de Notificação in municipalities of the State of Tocantins from 2001 to 2012. Units of analysis were the 139 municipalities of the State. Negative binomial log linear regression models were used to estimate incidence rate ratios. RESULTS: In bivariate analysis, the incidence rate ratios were significantly higher for municipalities with higher income ratio of the poorest 20.0% (1.47; 95%CI 1.19-1.81) and better Municipal Human Development Index (1.53; 95%CI 1.14-2.06). In multivariate analysis, the incidence rate ratios were significantly higher in municipalities with higher proportion of immigrants (1.31; 95%CI 1.11-1.55) and higher proportion of households with waste collection (1.37; 95%CI 1.11-1.69). There was a significant reduction in the incidence rate ratio with increased coverage of the Bolsa Família Program (0.98; 95%CI 0.96-0.99). CONCLUSIONS: Control programs need to focus on activities in municipalities of greater social vulnerability with intersectoral investment for the improvement of the living conditions of the population. OBJETIVO: Identificar fatores socioeconômicos, demográficos, operacionais e de serviços de saúde associados à ocorrência da hanseníase em um estado hiperendêmico do norte do Brasil. MÉTODOS: Estudo ecológico com dados secundários do Sistema de Informações de Agravos de Notificação em municípios do estado do Tocantins de 2001 a 2012. As unidades de análise foram os 139 municípios do estado. Modelos de regressão log linear binomial negativa foram utilizados para estimar as razões de taxas de incidência. RESULTADOS: Na análise bivariada, a razão de taxa de incidência foi significativamente maior para os municípios com maior razão de renda dos 20,0% mais pobres (1,47; IC95% 1,19-1,81) e melhor Índice de Desenvolvimento Humano Municipal (1,53; IC95% 1,14-2,06). Na múltipla, a razão de taxa de incidência foi significativamente superior em municípios com maior concentração de imigrantes (1,31; IC95% 1,11-1,55) e proporção de domicílios com coleta de lixo (1,37; IC95% 1,11-1,69). Houve redução significativa da razão de taxa de incidência com o aumento da cobertura do programa bolsa família (0,98; IC95% 0,96-0,99). CONCLUSÕES: Os programas de controle precisam focar as atividades em municípios de maior vulnerabilidade social com investimentos intersetoriais para a melhoria das condições de vida da população.

Clinical and epidemiological profile of leprosy patients attended at Ceará, 2007-2011.

BACKGROUND: Leprosy is an infectious chronic condition associated with potentially serious physical, social and psychological impacts. OBJECTIVES: To characterize the clinical and epidemiological profile of leprosy patients treated from 2007 to 2011 in the University Hospital of Ceará, Northeastern Brazil. METHODS: This is a retrospective and descriptive study. The study population consisted of residents in the state of Ceará treated in a dermatology clinic between 2007-2011. Clinical and epidemiological data analyzed were obtained from medical records and from the database of national Information System for Notifiable Diseases. RESULTS: 475 cases were analyzed, mostly women (51.8%), aged 45-59 years (35.0%) - mean of 45.2 years at diagnosis - with 6.3% of children under 15 , with low education (73.7%), white color (68.8%), residency in the city of Fortaleza (82.3%), and no defined work occupation (59.6%). At diagnosis, most patients were multibacillary (MB) (65.5%), had borderline clinical form (48.0%), and 22.7% had physical disability (8.0% with grade 2), predominantly in MB cases (p <0.001). We observe worsening of disability in 5.1% of cases post-MDT. The proportion of cases with reactional episodes was 42.7%, mainly during MDT (51.2%). CONCLUSION: This is the first study conducted in this hospital context, revealing late diagnosis, high burden of disease, hidden endemicity, and high social vulnerability in the state of Ceará. This study reinforces the need to strengthen health care network for timely diagnosis and treatment, aiming at longitudinality of assistance.

Temporal trends of leprosy in a Brazilian state capital in Northeast Brazil: epidemiology and analysis by joinpoints, 2001 to 2012. / Tendência temporal da hanseníase em uma capital do Nordeste do Brasil: epidemiologia e análise por pontos de inflexão, 2001 a 2012.

The objective of this study was to characterize epidemiological and temporal trends of leprosy in the city of Fortaleza, Ceará, Brazil, from 2001 to 2012. A total of 9,658 new cases were reported. Their temporal trend was analyzed by the jointpoint regression model. The overall detection rate showed a declining trend, with annual percent change (APC) of -4.0 and 95% confidence interval (95%CI) -5.6 - -2.3. The detection rate in children under 15 years of age (APC = -1.4; 95%CI -5.4 - 2.8) and the detection rate of disability grade 2 (APC = -0.8; 95%CI -4.5 - 3.1) were stable. The proportion of female patients was descending (APC = -1,5; 95%CI -2.3 - -0.8). The proportion of multibacillary cases from 2005 to 2012 (APC = 1.4; 95%CI 0.6 - 2.3) and among them, lepromatous cases from 2004 to 2012 (APC = 6.0; 95%CI 3.4 - 8.6) were increasing. There was stability in the proportion of cases with grade 1 (APC = 1.4; 95%CI -0.9 - 3.7) and grade 2 disability (APC = 3.7; 95%CI -0.1 - 7.8). Despite the trend towards a reduction in detection, the disease transmission persists in the city. The data also suggest late diagnosis.

Physical disabilities at diagnosis of leprosy in a hyperendemic area of Brazil: trends and associated factors.

INTRODUCTION: Tocantins State in north Brazil remains endemic for leprosy, with high detection rates and occurrence of disabilities at diagnosis. We analyzed trends and identified factors associated with the occurrence of disability at diagnosis. METHODS: We analyzed data from the Notifiable Diseases Information System (SINAN). We included new leprosy cases resident in Tocantins, diagnosed between 2001 and 2012. RESULTS: During the study period, there were 14,532 new leprosy cases residing in Tocantins. Of these, 12,328 (84.9%) were assessed for degree of disability at diagnosis: 9,166 (74.4%) with Grade 0; 2,498 (20.3%) with Grade 1; and 664 (5.4%) with Grade 2 disability. The proportion of disability Grade 2 remained stable over time. Factors associated with Grade 2 at diagnosis included: male gender (RR = 2.24; CI: 1.89 - 2.65), age ≥ 45 years (RR = 5.31; CI: 3.21 - 8, 29), illiteracy (RR = 6.70; CI: 3.75 - 11.95), diagnosis made through mass campaigns (RR = 2.40; CI: 1.50 - 3.85), and residency in rural areas (RR = 1.28; CI: 1.06 - 1.5). Grade 2 disabilities at diagnosis were also more common in the presence of ≥ 5 five skin lesions (RR = 4.42, CI: 3.74 - 5.21), leprosy reactions (RR = 2.78; CI: 2.31 - 3.33), multibacillary disease (RR = 7.43; CI: 6.11 - 9.04), and lepromatous clinical form (RR = 16.53, CI: 12.10 - 20.60). CONCLUSIONS: The leprosy control programme should focus on socio-economically disadvantaged and difficult-to-reach population groups. Leprosy mass campaigns and other collective examinations, to be integrated with other disease control programmes, may be an effective means to reduce disability degree at diagnosis.

Spatial patterns of leprosy in a hyperendemic state in Northern Brazil, 2001-2012.

OBJECTIVE: To describe the spatial patterns of leprosy in the Brazilian state of Tocantins. METHODS: This study was based on morbidity data obtained from the Sistema de Informações de Agravos de Notificação (SINAN - Brazilian Notifiable Diseases Information System), of the Ministry of Health. All new leprosy cases in individuals residing in the state of Tocantins, between 2001 and 2012, were included. In addition to the description of general disease indicators, a descriptive spatial analysis, empirical Bayesian analysis and spatial dependence analysis were performed by means of global and local Moran's indexes. RESULTS: A total of 14,542 new cases were recorded during the period under study. Based on the annual case detection rate, 77.0% of the municipalities were classified as hyperendemic (> 40 cases/100,000 inhabitants). Regarding the annual case detection rate in < 15 years-olds, 65.4% of the municipalities were hyperendemic (10.0 to 19.9 cases/100,000 inhabitants); 26.6% had a detection rate of grade 2 disability cases between 5.0 and 9.9 cases/100,000 inhabitants. There was a geographical overlap of clusters of municipalities with high detection rates in hyperendemic areas. Clusters with high disease risk (global Moran's index: 0.51; p < 0.001), ongoing transmission (0.47; p < 0.001) and late diagnosis (0.44; p < 0.001) were identified mainly in the central-north and southwestern regions of Tocantins. CONCLUSIONS: We identified high-risk clusters for transmission and late diagnosis of leprosy in the Brazilian state of Tocantins. Surveillance and control measures should be prioritized in these high-risk municipalities.

Leprosy-related mortality in Brazil: a neglected condition of a neglected disease.

BACKGROUND: Leprosy is a public health problem and a neglected condition of morbidity and mortality in several countries of the world. We analysed time trends and spatiotemporal patterns of leprosy-related mortality in Brazil. METHODS: We performed a nationwide population-based study using secondary mortality data. We included all deaths that occurred in Brazil between 2000 and 2011, in which leprosy was mentioned in any field of death certificates. RESULTS: Leprosy was identified in 7732/12 491 280 deaths (0.1%). Average annual age-adjusted mortality rate was 0.43 deaths/100 000 inhabitants (95% CI 0.40-0.46). The burden of leprosy deaths was higher among males, elderly, black race/colour and in leprosy-endemic regions. Lepromatous leprosy was the most common clinical form mentioned. Mortality rates showed a significant nationwide decrease over the period (annual percent change [APC]: -2.8%; 95% CI -4.2 to -2.4). We observed decreasing mortality rates in the South, Southeast and Central-West regions, while the rates remained stable in North and Northeast regions. Spatial and spatiotemporal high-risk clusters for leprosy-related deaths were distributed mainly in highly endemic and socio-economically deprived regions. CONCLUSIONS: Leprosy is a neglected cause of death in Brazil since the disease is preventable, and a cost-effective treatment is available. Sustainable control measures should include appropriate management and systematic monitoring of leprosy-related complications, such as severe leprosy reactions and adverse effects to multidrug therapy.
