Perfil sociodemográfico e laboratorial dos pacientes submetidos à hemodiálise em um centro de referência do Estado do Ceará / Sociodemographic and laboratory profile of patients undergoing hemodialysis in a reference center in the State of Ceará / Perfil sociodemográfico y de laboratorio de dos pacientes sometidos a hemodiálisis en un centro de referencia del Estado de Ceará

A Doença Renal Crônica (DRC) é uma importante redução da função renal que causa alterações no metabolismo dos indivíduos. Para acompanhar a progressão da DRC e prevenir possíveis complicações, foi realizada uma pesquisa para avaliar o perfil sociodemográfico, bioquímico e hematológico de pacientes com Insuficiência Renal Crônica (IRC) submetidos a hemodiálise. Esta pesquisa foi quantitativa, descritiva e transversal de caráter retrospectivo, realizada por meio da análise de dados secundários contidos nos prontuários dos pacientes. A coleta de dados ocorreu no Centro de Hemodiálise da cidade de Russas, no Ceará. A amostra foi constituída por 161 pacientes com DRC, sendo 63,35% do sexo masculino e 85,71% pardos, com uma idade média de 54,39 anos. Desses, 63,97% tinham entre 2 e 10 anos de tratamento e 57,76% possuíam ensino fundamental incompleto. 19,25% residiam em Russas. Resultados: Após a hemodiálise, os resultados mostraram 44 mg/dL de Ureia, 48,44% dos pacientes com valores normais. A hemoglobina e hematócrito médios foram 11,8 g/dL e 33,7%, respectivamente, sendo que 63,35% tiveram valores reduzidos. 85,10% dos pacientes tiveram contagem de plaquetas normal, 72,04% níveis adequados de ferro e albumina, 52,79% tiveram níveis elevados de ferritina, 23,61% redução de transferrina e níveis lipídicos satisfatórios. 79,50% apresentaram níveis séricos de potássio dentro da normalidade, 12,42% de fósforo acima do normal, 85,09% de cálcio dentro dos valores normais, 39,13% de PTHi normais e 86,33% de glicose dentro dos valores considerados normais. Com base nos resultados, concluiu-se que todos os pacientes em tratamento hemodialítico apresentam diversas alterações em decorrência da DRC e do próprio processo de tratamento. Portanto, a realização de exames para avaliar ou monitorar possíveis complicações da IRC é essencial para criar estratégias e intervenções mais eficazes, que melhorem a assistência prestada a esses pacientes e, consequentemente, da qualidade e expectativa de vida dos mesmos.

Chronic Kidney Disease (CKD) is an important reduction in kidney function that causes changes in the metabolism of individuals. To monitor the progression of CKD and prevent possible complications, a survey was carried out to assess the sociodemographic, biochemical and hematological profile of patients with Chronic Renal Failure (CRF) undergoing hemodialysis. This research was quantitative, descriptive and cross-sectional with a retrospective character, carried out through the analysis of secondary data contained in the patients' medical records. Data collection took place at the Hemodialysis Center in the city of Russas, Ceará. The sample consisted of 161 patients with CKD, 63.35% male and 85.71% brown, with an average age of 54.39 years. Of these, 63.97% had between 2 and 10 years of treatment and 57.76% had incomplete primary education. 19.25% resided in Russas. Results: After hemodialysis, the results showed 44 mg/dL of Urea, 48.44% of patients with normal values. Average hemoglobin and hematocrit were 11.8 g/dL and 33.7%, respectively, with 63.35% having reduced values. 85.10% of the patients had normal platelet counts, 72.04% had adequate levels of iron and albumin, 52.79% had high levels of ferritin, 23.61% had reduced transferrin and satisfactory lipid levels. 79.50% had serum levels of potassium within the normal range, 12.42% of phosphorus above normal, 85.09% of calcium within normal values, 39.13% of PTHi normal and 86.33% of glucose within the values considered normal. Based on the results, it was concluded that all patients on hemodialysis have several changes due to CKD and the treatment process itself. Therefore, carrying out tests to assess or monitor possible complications of CRF is essential to create more effective strategies and interventions that improve the care provided to these patients and, consequently, their quality and life expectancy.

La Enfermedad Renal Crónica (ERC) es una reducción importante de la función renal que provoca cambios en el metabolismo de los individuos. Para monitorizar la evolución de la ERC y prevenir posibles complicaciones, se realizó una encuesta para evaluar el perfil sociodemográfico, bioquímico y hematológico de los pacientes con Insuficiencia Renal Crónica (IRC) en hemodiálisis. Esta investigación fue cuantitativa, descriptiva y transversal con carácter retrospectivo, realizada a través del análisis de datos secundarios contenidos en las historias clínicas de los pacientes. La recolección de datos ocurrió en el Centro de Hemodiálisis de la ciudad de Russas, Ceará. La muestra estuvo constituida por 161 pacientes con ERC, 63,35% del sexo masculino y 85,71% pardos, con una edad media de 54,39 años. De estos, 63,97% tenían entre 2 y 10 años de tratamiento y 57,76% tenían primaria incompleta. El 19,25% residía en Russas. Resultados: Posterior a la hemodiálisis los resultados arrojaron 44 mg/dL de Urea, 48,44% de los pacientes con valores normales. La hemoglobina y el hematocrito medios fueron 11,8 g/dl y 33,7 %, respectivamente, con un 63,35 % con valores reducidos. El 85,10% de los pacientes presentaba plaquetas normales, el 72,04% presentaba niveles adecuados de hierro y albúmina, el 52,79% presentaba niveles elevados de ferritina, el 23,61% presentaba transferrina reducida y niveles satisfactorios de lípidos. El 79,50% presentaba niveles séricos de potasio dentro de la normalidad, el 12,42% de fósforo por encima de lo normal, el 85,09% de calcio dentro de los valores normales, el 39,13% de PTHi normal y el 86,33% de glucosa dentro de los valores considerados normales. Con base en los resultados, se concluyó que todos los pacientes en hemodiálisis tienen varios cambios debido a la ERC y al propio proceso de tratamiento. Por tanto, la realización de pruebas para evaluar o monitorizar las posibles complicaciones de la IRC es fundamental para crear estrategias e intervenciones más eficaces que mejoren la atención a estos pacientes y, en consecuencia, su calidad y esperanza de vida.

O ensino da saúde coletiva no Brasil: uma revisão integrativa / Teaching public health in Brazil: an integrative review

RESUMO O ensino da saúde coletiva no Brasil contribui para o desenvolvimento técnico-científico do campo, transcendendo a mera abordagem de programas de saúde de forma fragmentada. Assim, objetivou-se neste estudo compreender a operacionalização do ensino em saúde coletiva, na graduação e pós-graduação stricto sensu, no Brasil. Trata-se de uma revisão integrativa de literatura a partir da busca nas bases de dados PubMed, Scopus, PsycINFO, Literatura Latino-americana e do Caribe em Ciências da Saúde (Lilacs), Scientific Electronic Library Online (SciELO) e Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde (Bireme). Foram analisados 21 artigos por título, autor, ano, caracterização e/ou objetivo, metodologia e principais resultados. Conclui-se que a institucionalização de cursos de pós-graduação no campo da saúde coletiva seguiu o movimento educacional da universidade e a Reforma Sanitária Brasileira, ao passo que cursos de graduação só ocorreram na última década. O marco constitucional de 1988 define o ordenamento de recursos humanos para a formação profissional no e para o sistema de saúde no País.

ABSTRACT The teaching of public health in Brazil contributes to the technical-scientific development of the field, transcending the mere approach of health programs in a fragmented way. Thus, the objective of this study was to understand the operationalization of teaching in public health, in the stricto sensu undergraduate and graduate programs, in Brazil. This is an integrative literature review based on a search in PubMed, SCOPUS, PsycINFO, Latin American and Caribbean Health Sciences (LILACS), Scientific Electronic Library Online (SciELO) databases, and the Latin American and Caribbean Center on Health Sciences Information (BIREME). Twenty-one articles were analyzed by title, author, year, characterization and/or objective, methodology, and main results. It is concluded that the institutionalization of graduate courses in the field of public health followed the educational movement of the university and the Brazilian Health Reform, while undergraduate courses only took place in the last decade. The 1988 constitutional framework defines the ordering of human resources for professional training in and for the country's health system.

Seroprevalence and risk factors of Chagas disease in a rural population of the Quixeré municipality, Ceará, Brazil.

INTRODUCTION: This study estimated the seroprevalence and risk factors of Chagas disease (CD) in a population of the Quixeré municipality, Ceará. METHODS: We conducted serological methods to detect the Trypanosoma cruzi infection. The other variables were evaluated by a standardized questionnaire. RESULTS: The estimated prevalence of CD was 3.7%. Male sex, age >40 years, being farmers, low education level, origin from rural areas, and being born in Quixeré were significantly associated with infection. CONCLUSION: CD persists in this rural population of Northeast Brazil. Poverty, low education, and limited information regarding CD are critical issues that need to be addressed.

Prevalência da Infecção pelo Trypanosoma cruzi em Doadores de Sangue / Prevalence of Trypanosoma Cruzi Infection in Blood Donors

Resumo Fundamento A doença de Chagas (DC) é considerada um problema de saúde pública na América Latina. A região nordeste, principalmente o estado do Ceará, ainda representa grande preocupação em termos de risco de transmissão da doença. Objetivo Estimar a prevalência de T. cruzi em doadores de sangue do estado do Ceará. Métodos Trata-se um de estudo retrospectivo descritivo realizado no período de 2010 a 2015, a partir de dados registrados no sistema informatizado do Centro de Hematologia e Hemoterapia do Ceará (HEMOCE). Resultados Dos 763.731 potenciais doadores de sangue, 14.159 foram considerados impedidos de fazer a doação devido à sorologia, sendo que 1.982 (0,33%) o foram devido à positividade/inconclusão para doença de Chagas. Compareceram à Hemorrede para a repetição 425 indivíduos, sendo confirmados 28,2% (120/425) como impedidos de doar devido a DC. Conclusão Não houve redução significativa das sorologias positivas/inconclusivas no período entre 2010-2015, porém foi observada redução em relação a 1996/1997 no estado. A determinação da prevalência da doença de Chagas em bancos de sangue pode ser relevante como indicador do risco de transmissão transfusional em determinada região. Novos testes sorológicos para triagem com melhor acurácia são necessários, reduzindo o descarte desnecessário de bolsas de sangue, os custos para o Sistema Único de Saúde e a insegurança para os pacientes e familiares.

Abstract Background Chagas disease (CD) is considered a public health problem in Latin America. The northeastern region, especially the state of Ceará, still represents a major concern in terms of the risk of transmission of CD. Objective To estimate the prevalence of T. cruzi in blood donors from the state of Ceará. Methods This is a retrospective descriptive study that was performed in the period from 2010 to 2015 from data recorded in the computerized system of the Hematology and Hemotherapy Center of Ceará (HEMOCE in Portuguese). Results Of the 763,731 potential blood donors, 14,159 were serologically ineligible; 1,982 (0.33%) were serologically ineligible due to positive / inconclusive diagnosis for CD. A total of 425 individuals came to the HEMOCE to repeat the test, with 28.2% (120/425) declared ineligible for donations due to CD. Conclusion No significant reduction of positive / inconclusive serology was observed in the period between 2010 and 2015, but a reduction was observed when compared to 1996/1997 in the state. The determination of the prevalence of CD in blood banks may be relevant as an indicator of the risk of CD transmission through blood transfusions in a given region. New serological tests for triage with better accuracy in screening are needed, in an attempt to reduce the unnecessary disposal of blood bags, reduce costs for the Brazilian Unified Health System, and diminish insecurity for the patient and family members.

Burden of schistosomiasis-related mortality in Brazil: epidemiological patterns and spatial-temporal distribution, 2003-2018.

OBJECTIVE: To characterise the epidemiological patterns and the spatial-temporal distribution of schistosomiasis-related mortality in Brazil from 2003 to 2018. METHODS: A national population-based ecological study that used official data from the Mortality Information System. The data included all deaths recorded in Brazil from 2003 to 2018 in which schistosomiasis was mentioned in the death certificate as an underlying or associated cause of death (multiple causes). The municipalities of residence were used as units of geographic analysis, and standardised and smoothed mortality rates (per 100 000 inhabitants) were calculated using the local empirical Bayes method. Spatial autocorrelation was evaluated using global and local Moran indexes. To analyse the spatial dependence, the Getis-Ord G and Gi* statistics were used. RESULTS: During the study period, 18 421 113 deaths were recorded in Brazil. Schistosomiasis was mentioned in 11 487 deaths (proportional mortality: 0.06%); for 8141 deaths (70.87%), it was listed as the underlying cause, and for 3346 deaths (29.13%), it was listed as an associated cause. The mean mortality rate was 0.38 deaths/100 000 inhabitants. Individuals ≥ 70 years of age (RR: 115.34, 95% CI: 68.56-194.03) and residents in the Northeast region (RR: 10.81, 95% CI: 5.95-19.66) presented higher risks related to schistosomiasis. Municipalities with high mortality rates were identified in all regions, and high-risk clusters were found in municipalities located in the Northeast and Southeast regions of the country. CONCLUSIONS: Schistosomiasis remains an important cause of death in persistently endemic areas in Brazil, particularly in those with a high prevalence of the disease and a marked parasite load.

OBJECTIF: Caractériser les profils épidémiologiques et la distribution spatio-temporelle de la mortalité liée à la schistosomiase au Brésil de 2003 à 2018. MÉTHODES: Une étude écologique nationale basée sur la population qui a utilisé les données officielles du système d'information sur la mortalité. Les données incluaient tous les décès enregistrés au Brésil de 2003 à 2018 dans lesquels la schistosomiase était mentionnée dans le certificat de décès comme cause sous-jacente ou associée (causes multiples) de décès. Les municipalités de résidence ont été utilisées comme unités d'analyse géographique et les taux de mortalité normalisés et lissés (pour 100.000 habitants) ont été calculés à l'aide de la méthode empirique locale de Bayes. L'autocorrélation spatiale a été évaluée à l'aide d'indices de Moran globaux et locaux. Pour analyser la dépendance spatiale, les statistiques de Getis-Ord G et Gi* ont été utilisées. RÉSULTATS: Au cours de la période d'étude, 18.421.113 décès ont été enregistrés au Brésil. La schistosomiase a été mentionnée dans 11.487 décès (mortalité proportionnelle: 0,06%); pour 8.141 décès (70,87%), elle a été répertoriée comme la cause sous-jacente et pour 3.346 décès (29,13%), comme cause associée. Le taux de mortalité moyen était de 0,38 décès/100.000 habitants. Les personnes âgées de ≥70 ans (RR: 115,34 ; IC95%: 68,56 à 194,03) et les résidents de la région du Nord-Est (RR: 10,81 ; IC95%: 5,95 à 19,66) présentaient des risques plus élevés liés à la schistosomiase. Des municipalités présentant des taux de mortalité élevés ont été identifiées dans toutes les régions et des grappes à haut risque ont été trouvées dans des municipalités situées dans les régions du nord-est et du sud-est du pays. CONCLUSIONS: La schistosomiase reste une cause importante de mortalité dans les zones d'endémie persistante du Brésil, en particulier dans celles à forte prévalence de la maladie et à forte charge parasitaire.

Epidemiology and predictors of occurrence of SCHISTOSOMA MANSONI infection in a low-endemicity area in northeast Brazil

In Latin America 96% of the cases of schistosomiasis occur in Brazil in low-socioeconomic status populations. The epidemiological characteristics and occurrence predictors of Schistosoma mansoni infection were determined in the Bananeiras community, located in Capistrano, a town in Ceará state, Brazil. Sanitary, environmental, socioeconomic, and behavioral data were collected using a semi-structured questionnaire. An investigation to assess S. mansoni infection was conducted using the Kato-Katz and Point-of-Care Circulating Cathodic Antigen (POC-CCA) methods. From the 258 subjects were analyzed, 54.3% (n=140) were women, median age 30 years. Thirty-three (12.8%) individuals were positive by either egg- and/or CCA-positivity. The highest positivity rate was found in the 30-39 year old group. There was no piped water supply, sewage network or municipal refuse collection service. Most individuals were illiterate or had not finished elementary school (66.3%). About 29.1% of the families had a monthly income below one Brazilian minimum wage and 91.1% reported contact with natural water sources. We found an association between infection and age group of 20-40 years, illiteracy, household with 7 inhabitants or more, household with up to 3 rooms and an outhouse. Contrarily, being 40 years old or older and household with up to 6 inhabitants were not risk factors. Schistosomiasis remains a public health problem in this municipality, evidencing a strong association with low socioeconomic conditions and high vulnerability. These findings reinforce the importance of identifying the factors associated with the infection for more effective guidance in actions in control programs targeting schistosomiasis prevention and control.

Trypanosoma cruzi seroprevalence among solid organ donors in Ceará State, Brazil.

INTRODUCTION: The transmission of Chagas disease (CD) through blood transfusion, organ transplantation, and oral transmission has gained greater visibility as a result of intensified vector control activities in endemic regions and to control CD in non-endemic regions. In Brazil, Ceará is one of the states that perform the most organ transplants. Therefore, the objective of this study was to assess the prevalence of Trypanosoma cruzi infection in organ donor candidates. METHODS: A retrospective analysis was performed on data from potential organ donors at the Center of Transplantation of the State of Ceará from 2010 - 2015. RESULTS: Data from a total of 2,822 potential donors were obtained, of which 1,038 were effective donors and 1,784 were excluded, likely due to lack of family authorization or medical contraindication. The prevalence of T. cruzi infection among these potential donors was 1.3% (n = 29). The majority of infected donors were males aged 41 - 60 years, residing in the interior of the state. Interestingly, 72.4% (n = 21) had positive or inconclusive serology for additional infections, such as cytomegalovirus, hepatitis B and C, and toxoplasmosis. Probability analysis revealed that stroke was the most common cause of death among potential donors with CD. CONCLUSIONS: There was a high prevalence of CD and other coinfections among potential solid organ donors in Ceará, and statistical tests have shown that these individuals are at increased risk of stroke when compared to potential non-reactive donors. This work highlights the importance of screening DC infection in potential donors.

Trypanosoma cruzi seroprevalence among solid organ donors in Ceará State, Brazil

Abstract INTRODUCTION: The transmission of Chagas disease (CD) through blood transfusion, organ transplantation, and oral transmission has gained greater visibility as a result of intensified vector control activities in endemic regions and to control CD in non-endemic regions. In Brazil, Ceará is one of the states that perform the most organ transplants. Therefore, the objective of this study was to assess the prevalence of Trypanosoma cruzi infection in organ donor candidates. METHODS: A retrospective analysis was performed on data from potential organ donors at the Center of Transplantation of the State of Ceará from 2010 - 2015. RESULTS: Data from a total of 2,822 potential donors were obtained, of which 1,038 were effective donors and 1,784 were excluded, likely due to lack of family authorization or medical contraindication. The prevalence of T. cruzi infection among these potential donors was 1.3% (n = 29). The majority of infected donors were males aged 41 - 60 years, residing in the interior of the state. Interestingly, 72.4% (n = 21) had positive or inconclusive serology for additional infections, such as cytomegalovirus, hepatitis B and C, and toxoplasmosis. Probability analysis revealed that stroke was the most common cause of death among potential donors with CD. CONCLUSIONS: There was a high prevalence of CD and other coinfections among potential solid organ donors in Ceará, and statistical tests have shown that these individuals are at increased risk of stroke when compared to potential non-reactive donors.

Identification of Biomphalaria sp. and other freshwater snails in the large-scale water transposition project in the Northeast of Brazil.

The wide eco-bio-social intervention generated by the SaoFrancisco River Integration Project (PISF) may contribute to the dispersion or introduction of schistosomiasis intermediate hosts in areas without prior recording. The objective was to characterize the limnic malacofauna and its distribution along watersheds involved in the PISF. A cross-sectional study based on the collection of mollusks from 33 water bodies, from Aurora, Brejo Santo, Jaguaretama, Jaguaribara, Jati e Mauriti municipalities in the Ceara (CE) State was developed. The conchological characteristics were used to identify snails at the genus level. The snails of the genus Biomphalaria were analyzed for the presence of Schistosoma mansoni cercariae and the molecular identification (only mollusks from Brejo Santo-CE) for differentiation between species. The following species were found: Biomphalaria sp.; Drepanotrema sp.; Melanoides sp.; Physa sp.; and Pomacea sp. Pomacea sp. (75.8%) and Biomphalaria sp. (72.7%) were the most prevalent species. All municipalities showed Biomphalaria sp. Biomphalaria straminea (Porcos Stream) and Biomphalaria kuhniana was identified in the Boi 1 and Cipo reservoirs (Brejo Santo). The evaluated municipalities under the influence of the PISF present areas with potential for schistosomiasis transmission. It is necessary to intensify control actions and health surveillance in these areas.

Insect vectors of Chagas disease (Trypanosoma cruzi) in Northeastern Brazil.

INTRODUCTION: Chagas disease remains a public health problem in the rural and urban areas of 19 countries in the Americas. METHODS: The aim of the present study was to investigate the Trypanosoma cruzi infection rate of triatomines collected from both intra- and peridomiciliary areas in eleven municipalities of Southeastern Ceará, Brazil, from 2009 to 2015. RESULTS: A total of 32,364 triatomine specimens, including nymphs and adults, were collected, and 31,736 (98.06%) of these were examined. More nymphs were collected than adults, and the greatest number of triatomines (n = 8,548) was collected in 2010, for which the infection rate was 1.3%, with the highest rate of infections observed for specimens from Quixere. The species collected during the study were identified as Triatoma pseudomaculata, Triatoma brasiliensis, Panstrongylus megistus, Panstrongylus lutzi, and Rhodnius nasutus, with T. pseudomaculata being the most abundant (n = 19,962). CONCLUSIONS: These results verify the presence of triatomines in both intra- and peridomiciliary areas, thereby ensuring persistence of the pathogen and consequently, the disease, as the presence of infected vectors in households is an important risk factor. According to these findings, the Chagas Disease Control Program should intensify its efforts in order to prevent the spread of the disease.

[Satisfaction of Chagas disease patients attended at a pharmaceutical care service in the State of Ceará, Brazil]. / Satisfação dos pacientes com doença de Chagas atendidos por um serviço de atenção farmacêutica no estado do Ceará, Brasil.

In 2005, a pharmaceutical care service was created in the State of Ceará to provide pharmacotherapeutic follow-up for individuals infected with Trypanosoma cruzi (Chagas Disease). After 10 years of operation, an evaluation was conducted to assess the degree of satisfaction of patients treated under the service. This prospective study used a questionnaire comprising the following sections: socioeconomic data; infrastructure, facilities and operations; pharmaceutical care; and importance of the service. Seventy patients of both sexes and over 18 years of age were interviewed between August 2014 and May 2015. As for infrastructure, location and operation, the average grades show a high level of patient satisfaction. Regarding pharmaceutical care, most patients reported being satisfied and considered "being well treated" to be the most important aspect during treatment. In addition, all patients (100%) rated the service as very important and would recommend it to other individuals. Overall, the study showed a high level of patient satisfaction with the service. There is, however, still much to work to be done on this service in order to promote greater access and qualified care to fully achieve a humanized model focused on patient needs.

Detection of schistosomiasis in an area directly affected by the São Francisco River large-scale water transposition project in the Northeast of Brazil

Abstract INTRODUCTION: The development of the São Francisco River Integration Project [Projeto de Integração do Rio São Francisco (PISF)] in the State of Ceará, Brazil, has resulted in environmental and socioeconomic changes with potential risks to public health. We aimed to determine the presence of Schistosoma mansoni infections in schoolchildren (aged 7-14 years) and workers from the construction site in an area under the direct influence of the PISF in the municipality of Brejo Santo-CE, to aid in the prevention and control of schistosomiasis. METHODS: We conducted a cross-sectional study using two S. mansoni-detection methods: detection of S. mansoni eggs by the Kato-Katz parasitological method in stool samples (assessed in triplicate for each sample) and S. mansoni circulating cathodic antigen by the point-of-care immunochromatographic rapid test (POC-CCA) in urine. RESULTS In general, the positivity rates for S. mansoni detection were 1.9% (2/106) among schoolchildren and 2.9% (4/138) among workers. No child had evidence of S. mansoni eggs in their stools; 1.9% tested positive by the POC-CCA method. Among workers, two (1.4%) tested positive by the Kato-Katz test and three (2.2%) by the POC-CCA test. If the POC-CCA test results that were scored as traces were considered negative, then the positivity rates dropped to 0.9% and 0.7% for schoolchildren and workers, respectively. CONCLUSIONS: The active transmission of schistosomiasis in a region covered by the PISF was recognized, reinforcing the necessity to consolidate surveillance and control actions, as well as structural sanitation measures to reverse the social determinants of the disease.

Analysis of the seroprevalence of and factors associated with Chagas disease in an endemic area in Northeastern Brazil

ABSTRACT INTRODUCTION: Chagas disease (CD) is currently considered a neglected disease; hence, identifying the factors associated with its high prevalence is essential. This study aimed to identify the seroprevalence of and the possible factors associated with CD in inhabitants of the City of Limoeiro do Norte, Northeastern Brazil. METHODS: Between April and November 2013, blood collection was conducted and a semi-structured questionnaire was administered. Blood samples that showed positive or possible serology for anti-Trypanosoma cruzi antibodies based on indirect immunofluorescence, hemagglutination indirect, and an enzyme-linked immunosorbent assay were analyzed. Associations between CD positivity and the study variables were analyzed using prevalence ratios (PR) with 95% confidence intervals (CI). RESULTS: A total of 812 individuals were analyzed, of which T. cruzi seropositivity was determined in 4.2% (34 individuals). Sociodemographic variables showing a significant association with T. cruzi positivity included age >50 years (PR = 27.6; 95% CI = 6.66-114.4), elementary level education (PR = 5.15; 95% CI = 1.83-14.47), and retirement (PR = 7.25; 95% CI = 3.72-14.14). Positivity for T. cruzi was 6.17 times higher in those who had a history of living in rammed earth houses compared with those who did not (95% CI = 2.19-17.37). There was no evidence of vertical transmission in the individuals studied. Among the individuals infected with T. cruzi, the majority reported having a comorbidity (p < 0.01). CONCLUSIONS: This study demonstrated the seroprevalence of CD and identified factors associated with a high prevalence of CD.

Evolução eletrocardiográfica e sorológica de pacientes com doença de Chagas crônica acompanhados por seis anos após o tratamento com benzonidazol / Electrocardiographic and serological evolution of patients with chronic Chagas disease followed-up for six years after treatment with benzonidazole

Introdução: O tratamento com benzonidazol na fase crônica da doença de Chagas ainda permanece controverso. O presente estudo objetiva avaliar a efetividade da quimioterapia com benzonidazol em pacientes chagásicos crônicos por meio de análises sorológica e eletrocardiográfica. Método: Estudo prospectivo histórico, com acompanhamento eletrocardiográfico e sorológico pelos métodos imunoenzimático (ELISA) e de imunofluorescência indireta uma vez por ano, antes e após o tratamento, entre 2005 e 2011. No perfil sociodemográfico dos 30 pacientes acompanhados o predomínio era do sexo masculino, faixa etária entre 25-64 anos, com primeiro grau incompleto e em sua maioria agricultores. Resultados: A análise sorológica por ELISA demonstrou queda significativa da densidade óptica das amostras coletadas antes (2005) e após o tratamento com benzonidazol (2011). Em relação à imunofluorescência indireta, os pacientes se mantiveram inalterados durante o acompanhamento (variação de no máximo uma diluição entre as amostras basal e final). Na avaliação eletrocardiográfica, 76,2% (16/21) dos pacientes apresentaram manutenção dos laudos eletrocardiográficos ao longo do estudo. Conclusão: Foram observadas regressões nas análises sorológicas dos pacientes tratados com benzonidazol, acompanhados por 6 anos, além da manutenção dos padrões eletrocardiográficos iniciais na maioria dos casos, o que pode sugerir um efeito benéfico do fármaco no tratamento desses pacientes na fase crônica da doença de Chagas.

Background: Treatment with benzonidazole in the chronic phase of Chagas disease remains controversial. This study is aimed at evaluating the effectiveness of chemotherapy with benzonidazole in chronic Chagas disease using serological and electrocardiographic analysis. Method: Historical prospective study with electrocardiographic and serological monitoring by enzyme immunoassay (ELISA) and indirect immunofluorescence once a year, before and after the treatment, from 2005 to 2011. In the socio-demographic profile of the 30 patients followed-up, there was a prevalence of males, ages ranged between 25-64 years, incomplete school education and most of them farmers. Results: ELISA serology showed a significant decrease in the optical density of the samples collected before (2005) and after treatment with benzonidazole (2011). Indirect immunofluorescence demonstrated patients remained unchanged during follow-up (maximum variation of one dilution between the baseline sample and 2011). In the electrocardiographic assessment, 76.2% (16/21) of the patients maintained their electrocardiographic reports throughout the study. Conclusion: Patients treated with benzonidazole and followed-up for 6 years presented a regression in serological analysis and maintenance of their baseline ECG patterns in most cases, which may suggest a beneficial effect of the drug in the chronic treatment of Chagas disease.
