Trends and spatial patterns of mortality related to neglected tropical diseases in Brazil

We analysed nationwide trends and spatial distribution of NTD-related mortality in Brazil. We included all death certificates in Brazil from 2000 to 2011, in which NTDs were recorded as any causes of death. A total of 100,814/12,491,280 (0.81%) death certificates were identified, which mentioned at least one NTD. Age-adjusted NTD-related mortality rates showed a significant decrease over time (annual percent change [APC]: − 2.1%; 95% CI: − 2.8 to − 1.3), with decreasing mortality rates in the Southeast, South, and Central-West regions, stability in the Northeast region, and increase in the North region. We identified spatial and spatiotemporal high-risk clusters for NTD-related mortality in all regions, with a major cluster covering a wide geographic range in central Brazil. Despite nationwide decrease of NTD-related mortality in the observation period, regional differences remain, with increasing mortality trends especially in the socioeconomically disadvantaged regions of the country. The existence of clearly defined high-risk areas for NTD-related deaths reinforces the need for integrated prevention and control measures in areas with highest disease burden

Temporal trends of leprosy in a Brazilian state capital in Northeast Brazil: epidemiology and analysis by joinpoints, 2001 to 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

Seroprevalence of Toxoplasma gondii IgG antibody in HIV/AIDS-infected individuals in Maputo, Mozambique

OBJETIVO Avaliar a prevalência de anticorpos IgG anti- Toxoplasma gondii em pessoas infectadas pelo HIV/Aids e a associação de variáveis demográficas e sociais. MÉTODOS Estudo transversal que incluiu a análise de dados sociodemográficos e laboratoriais de 200 pessoas infectadas por HIV/Aids, atendidas em unidade laboratorial em 2010 na Província de Maputo, Moçambique. Os dados foram coletados por meio de questionário autopreenchido por todos os participantes. Para a análise de anticorpos, amostras de plasma coletadas foram confirmadas para testagem de IgG anti- T. gondii por hemaglutinação. RESULTADOS A soroprevalência de IgG anti- T. gondii foi de 46,0% (IC95% 39,2;52,9), 39,3% (IC95% 29,5;50,0) em homens e de 50,9% (IC95% 41,9;59,8) em mulheres, sem diferença entre sexo (OR 1.30; IC95% 0.95;1.77; p = 0.12). A idade variou de 10 a 60 anos, com maior prevalência de infecção em grupos etários mais idosos, mas sem haver diferença significativa entre eles. Ter consumo regular de carne de gado bovino (OR 1,74; IC95% 1,04;2,89, p = 0,05), possuir criação de gatos/cães (OR 6,18; IC95% 3,60;10,62, p < 0,000) e ter contato regular com a terra (OR 3,38; IC95% 2,19;5,21, p < 0,000) estiveram significativamente associados ao risco de infecção latente. CONCLUSÕES A infecção por toxoplasmose apresenta alta prevalência na população de Moçambique, cujo risco amplia-se pelos aspectos culturais e comportamentais. A toxoplasmose pode ser responsável pela grande carga de morbimortalidade associada a lesões meningoencefálicas em pessoas com HIV/Aids no país.OBJETIVO Evaluar la prevalencia de anticuerpos IgG anti- Toxoplasma gondii en personas infectadas por VIH/SIDA y la asociación de variables demográficas y sociales. MÉTODOS Estudio transversal que incluyó el análisis de datos sociodemográficos y de laboratorio de 200 personas infectadas por VIH/SIDA, atendidas en unidad de laboratorio en 2010 en la Provincia de Maputo, Mozambique. Los datos fueron colectados por medio de cuestionario auto llenado por todos los participantes. Para el análisis de anticuerpos, las muestras de plasma colectadas fueron confirmadas para evaluación anti- T. gondii por hemaglutinación. RESULTADOS La seroprevalencia de IgG anti- T. gondii fue de 46% (IC95% 39,2;52,9), 39,3% (IC95% 29,5;50,0) en hombres y de 50,9% (41,9-59,8%) en mujeres, sin diferencia entre sexo (OR 1.30; IC95% 0.95;1.77; p = 0.12). La edad varió de 10 a 60 años, con mayor prevalencia de infección en grupos etarios más ancianos, pero sin haber diferencia significativa entre ellos. Consumir carne de ganado bovino regularmente (OR 1,74; IC95% 1,04;2,89, p = 0,05), poseer cria de gatos/perros (OR 6,18; IC95% 3,60;10,62, p < 0,000) y tener contacto regular con la tierra (OR 3,38; IC95% 2,19;5,21, p < 0,000) estuvieron significativamente asociados al riesgo de infección latente. CONCLUSIONES La infección por toxoplasmosis presenta alta prevalencia en la población de Mozambique, cuyo riesgo se amplía por los aspectos culturales y de comportamiento. La toxoplasmosis puede ser responsable por la gran carga de morbi-mortalidad asociada a lesiones meningoencefálicas en personas con VIH/SIDA en el país.OBJECTIVE To analyze the prevalence of IgG antibodies to Toxoplasma gondii in patients infected with HIV/AIDS and the association of demographic and social variables. METHODS Descriptive cross-sectional study that included the analysis of sociodemographic data and laboratory findings of 200 patients infected with HIV/AIDS treated in a laboratory unit in Maputo, Mozambique, in 2010. Individual data for all participants were collected with a self-administered questionnaire. Plasma samples were tested for IgG testing of anti- T. gondii using hemagglutination for the analysis of antibodies. RESULTS The seroprevalence of IgG anti- T. gondii was 46.0% (95%CI 39.2;52.9), 39.3% (95%CI 29.5;50.0) in men and 50.9% (95%CI 41.9;59.8) in women, with no difference between sex (OR 1.30; 95%CI 0.95;1.77; p = 0.12). Ages ranged from 10 to 60 years, with a higher prevalence of infection in older age groups, but with no significant difference between them. Regularly consuming cattle meat (OR 1.74; 95%CI 1.04;2.89, p = 0.05), breeding cats/dogs (OR 6.18; 95%CI 3.60;10.62, p < 0.000) and having regular contact with soil (OR 3.38; 95%CI 2.19;5.21; p < 0.000) were significantly associated with risk of latent infection. CONCLUSIONS Toxoplasmosis is an infection with high prevalence in Mozambique. Cultural and behavioral aspects increase the risk. Toxoplasmosis can be responsible in our environment by the great burden of morbidity and mortality associated with meningoencephalic injuries in patients with HIV/AIDS

Oral health conditions in leprosy cases in hyperendemic area of the Brazilian Amazon

Leprosy is a hyperendemic chronic condition in the Rondônia State . Despite the significant impact of oral health on the quality of life and clinical evolution of leprosy patients, systematic evaluation of oral health status has been neglected. To analyze the dental-clinical profile, self-perceived oral health and dental health service access of leprosy cases in the municipality of Cacoal in Rondônia State , North Brazil, from 2001 to 2012. A descriptive, cross-sectional study design was performed based on dental evaluation and standardized structured instruments. We investigated clinically assessed and self-perceived oral health status, as well as dental health service access. A total of 303 leprosy cases were included; 41.6% rated their oral health as good, and 42.6% reported being satisfied with their oral health. Self-reported loss of upper teeth was 45.5%. The clinical evaluation revealed that 54.5% had active caries. Most (97.7%) cases reported having been to the dentist at least once in their life and 23.1% used public health services. The poor standard of oral health in this population may increase the risk for leprosy reactions, consequently reducing quality of life. Low access to public health dental services and poor self-perceived oral health reinforce the need to achieve comprehensive health care in this population

Mortality related to tuberculosis-HIV/AIDS co-infection in Brazil, 2000-2011: epidemiological patterns and time trends

Co-infection of tuberculosis (TB)-HIV/AIDS is a persistent public health problem in Brazil. This study describes epidemiological patterns and time trends of mortality related to TB-HIV/AIDS co-infection. Based on mortality data from 2000-2011 (almost 12.5 million deaths), 19,815 deaths related to co-infection were analyzed. The average age-adjusted mortality rate was 0.97 deaths/100,000 inhabitants. The highest mortality rates were found among males, those in economically productive age groups, black race/color and residents of the South region. There was a significant reduction in the mortality coefficient at the national level (annual average percent change: -1.7%; 95% CI: -2.4; -1.0), with different patterns among regions: increases in the North, Northeast and Central regions, a reduction in the Southeast and a stabilization in the South. The strategic integration of TB-HIV/AIDS control programmes is fundamental to reduce the burden of mortality related to co-infection in Brazil

Coinfecção Trypanosoma cruzi/HIV: revisão sistemática (1980 - 2010)

INTRODUCTION: The co-infection Trypanosoma cruzi/HIV has been described as a clinical event of great relevance. The objective of this study wasto describe clinical and epidemiological aspects published in literature. METHODS: It is a systematic review of a descriptive nature from the databases Medline, Lilacs, SciELO, Scopus, from 1980 to 2010. RESULTS: There were 83 articles (2.8 articles/year) with a total of 291 cases. The co-infection was described in 1980 and this situation has become the defining AIDS clinical event in Brazil. This is the country with the highest number of publication (51.8%) followed by Argentina (27.7%). The majority of cases are amongst adult men (65.3%) native or from endemic regions with serological diagnosis in the chronic stage (97.9%) and indeterminate form (50.8%). Both diseases follow the normal course, but in 41% the reactivation of the Chagas disease occurs. The most severe form is the meningoencephalitis, with 100% of mortality without specific and early treatment of the T. cruzi. The medication of choice was the benznidazole on doses and duration normally used for the acute phase. The high parasitemia detected by direct or indirect quantitative methods indicated reactivation and its elevation is the most important predictive factor. The lower survival rate was related to the reactivation of the Chagas disease and the natural complications of both diseases. The role of the antiretroviral treatment on the co-infection cannot yet be defined by the knowledge currently existent. CONCLUSIONS: Despite the relevance of this clinical event there are still gaps to be filled.INTRODUÇÃO: A coinfecção Trypanosoma cruzi/HIV vem sendo sistematicamente descrita como um evento clínico de grande relevância. O objetivo deste estudo foi descrever aspectos clínicos e epidemiológicos publicados na literatura científica. MÉTODOS: Trata-se de revisão sistemática, de natureza descritiva, a partir da busca nas bases Medline, Lilacs, SciELO, Scopus, de 1980 a 2010. RESULTADOS: Identificou-se 83 artigos (2,8 artigos/ano), com um total de 291 casos registrados. A coinfecção foi descrita em 1980 e, no Brasil, tornou-se evento clínico definidor de AIDS. Este é o país com maior número de publicações (51,8%), seguido pela Argentina (27,7%). A maioria dos casos é de homens adultos (65,3%), naturais ou procedentes de regiões endêmicas, com diagnóstico sorológico, na fase crônica (97,9%) e na forma indeterminada (50,8%). As duas doenças evoluem naturalmente, mas em 41% dos casos ocorreu reativação da doença de Chagas. A forma mais grave é a meningoencefalite, com 100% de letalidade nos casos sem tratamento específico e precoce do T. cruzi. O medicamento indicado foi benznidazole, nas doses e duração utilizadas na fase aguda em imunocompetentes. O diagnóstico da reativação foi comprovado por alta parasitemia, detectada por métodos diretos ou indiretos quantitativos, sendo a sua elevação considerada fator preditivo para reativação. A menor sobrevida nacoinfecção esteve relacionada à reativação da doença de Chagas e às complicações naturais de ambas as doenças. O papel do tratamento antirretroviral sobre a evolução da coinfecção ainda não pode ser definido pelo conhecimento existente. CONCLUSÕES: Apesar da relevância deste evento clínico, ainda persistem lacunas a serem preenchidas.76277

Ampliação da sobrevida em crianças com AIDS no Brasil: resultados do segundo estudo nacional de 1999 a 2002

The objective of this study is to characterize survival in children with AIDS diagnosed in Brazil between 1999-2002, compared with the first national study (1983-1998). This national retrospective cohort study examined a representative sample of Brazilian children exposed to HIV from mother-to-child transmission and followed through 2007. The survival probability after 60 months was analyzed by sex, year of birth and death, clinical classification, use of antiretroviral therapy (ART) and prophylaxis for opportunistic diseases. 920 children were included. The survival probability increased: comparing cases diagnosed before 1988 with those diagnosed from 2001-2002 it increased by 3.5-fold (from 25% to 86.3%). Use of ART, initial clinical classification, and final classification were significant (p < 0.001) predictors of survival. Issues regarding quality of records and care were identified. The results point to the success of the Brazilian policy of providing ART. The improvement of clinical status contributes to quality of life, while indicating challenges, particularly practices to improve long-term care.Este estudo caracteriza a sobrevida em crianças com AIDS no Brasil entre 1999-2002, contextualizando com o primeiro estudo nacional (1983-1998). Trata-se de coorte histórica, com crianças expostas ao HIV por transmissão vertical e acompanhadas até 2007. A probabilidade de sobrevivência em 60 meses foi analisada segundo sexo, ano de nascimento e de óbito, classificação clínica, uso de terapia antirretroviral (TARV) e de profilaxia para doenças oportunistas. No total, 920 crianças foram incluídas. A probabilidade de sobrevivência foi ampliada 3,5 vezes nos dois períodos avaliados, passando de 25% antes de 1988 para 86,3% no período de 2001-2002. Uso de TARV, classificação clínica inicial e atual/final foram preditores que influíram significativamente (p < 0,001) para a ampliação da sobrevida. Os resultados deste estudo indicam o sucesso da política brasileira para a abordagem das crianças infectadas com HIV. A melhora do estado clínico contribuiu para melhora da qualidade de vida, mas sinaliza-se para a necessidade de incorporação de práticas pautadas na integralidade do cuidado

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 nonsignificant 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

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

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.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.
