Geography and public health: analysis of the epidemiological dynamics of meningitis in Brazil, between 2010 and 2019.

OBJECTIVE: To analyze the spatiotemporal epidemiological dynamics of meningitis in Brazil, between 2010 and 2019. METHODS: Descriptive ecological study with cases and deaths due to meningitis in Brazil (2010-2019) in the National Notifiable Diseases Information System (Sistema de Informações de Agravos de Notificação - SINAN). The following analyses were performed: (I) frequency analyses of cases and deaths, prevalence rates, mortality, lethality, Fisher's exact test, and chi-square test; (II) Prais-Winstein regression; and (III) Global, Local Moran's index, and Kernel density. RESULTS: 182,126 cases of meningitis were reported in Brazil, of which 16,866 (9.26%) resulted in death, with prevalence rates of 9.03/100,000 inhabitants, mortality of 0.84/100,000 inhabitants, and lethality of 9.26%. There was a noted trend of decreasing prevalence rates (-9.5%, 95% confidence interval - 95%CI -13.92; -4.96, p<0.01) and mortality (-11.74%, 95%CI -13.92; -9.48, p<0.01), while lethality remained stable (-2.08%, 95%CI -4.9; 0.8; p<0.1941). The majority of cases were viral meningitis (45.7%), among 1-9 years old (32.2%), while the highest proportion of deaths was due to bacterial meningitis (68%), among 40-59 years old (26.3%). In the Moran and Kernel maps of prevalence and mortality rates, municipalities in the South, Southeast, and the capital of Pernambuco in the Northeast stood out with high rates; as for lethality, the North, Northeast, and Southeast coastal areas were highlighted. CONCLUSION: A decrease in meningitis cases and deaths was found in this study; however, the lethality rate was higher in areas with lower prevalence, emphasizing the need to enhance actions for identifying, monitoring, and providing health care for cases, as well as expanding vaccination coverage.

Impact of cholecystectomy on the gut-liver axis and metabolic disorders.

Cholecystectomy is considered as a safe procedure to treat patients with gallstones. However, epidemiological studies highlighted an association between cholecystectomy and metabolic disorders, such as type 2 diabetes mellitus and metabolic dysfunction-associated steatotic liver disease (MASLD), independently of the gallstone disease. Following cholecystectomy, bile acids flow directly from the liver into the intestine, leading to changes in the entero-hepatic circulation of bile acids and their metabolism. The changes in bile acids metabolism impact the gut microbiota. Therefore, cholecystectomized patients display gut dysbiosis characterized by a reduced diversity, a loss of bacteria producing short-chain fatty acids and an increase in pro-inflammatory bacteria. Alterations of both bile acids metabolism and gut microbiota occurring after cholecystectomy can promote the development of metabolic disorders. In this review, we discuss the impact of cholecystectomy on bile acids and gut microbiota and its consequences on metabolic functions.

RESUMO Objetivo: Analisar a dinâmica epidemiológica espaçotemporal das meningites no Brasil, entre os anos de 2010 e 2019. Métodos: Estudo ecológico descritivo com os casos e óbitos por meningites no Brasil (2010-2019) no Sistema de Informações de Agravos de Notificação. Realizaram-se (I) análises de frequências dos casos e óbitos, taxas de prevalência, mortalidade, letalidade, testes de exato de Fisher e qui-quadrado; (II) regressão de Prais-Winsten; e (III) índice de Moran global, local e densidade de Kernel. Resultados: Notificaram-se 182.126 casos de meningites no Brasil, dos quais 16.866 (9,26%) evoluíram para óbito, com taxas de prevalência de 9,03/100.000/habitantes, mortalidade de 0,84/100.000/habitantes e letalidade de 9,26%. Destaca-se a tendência de decrescimento das taxas de prevalência (−9,5%, intervalo de confiança de 95% — IC95% −13,92; −4,96, p<0,01) e mortalidade (−11,74%, IC95% −13,92; −9,48, p<01,01), enquanto a letalidade se manteve estacionária (−2,08%, IC95% −4,9; 0,8; p<0,1941). A maioria dos casos foi de meningites virais (45,7%), entre 1 e 9 anos (32,2%), enquanto a maior parcela dos óbitos foi por meningites bacterianas (68%), entre 40 e 59 anos (26,3%). Nos mapas de Moran e Kernel das taxas de prevalência e mortalidade, destacaram-se com altas taxas os municípios do sul, sudeste e a capital de Pernambuco, no nordeste; já na letalidade, evidenciaram-se o norte, o nordeste e o litoral do sudeste. Conclusão: Encontrou-se decréscimo dos casos e óbitos por meningites neste estudo, entretanto a taxa de letalidade foi maior em áreas com menor prevalência, reforçando a necessidade do aprimoramento das ações de identificação, vigilância e assistência em saúde dos casos, bem como da ampliação da cobertura vacinal.

Spatial patterns of new leprosy cases in a northeastern state of Brazil, 2011-2021.

OBJECTIVE: To analyze the spatial patterns of leprosy in Pernambuco from 2011 to 2021. METHODS: This is an ecological epidemiological study, carried out with data from the Notifiable Diseases Information System, based on new cases of leprosy among inhabitants of Pernambuco, between 2011-2021. An empirical Bayesian analysis of local and spatial dependence was performed with the global and local Moran indices. RESULTS: 25,008 new cases of leprosy were registered with an annual case detection rate in the general population of 16.51 cases/100,000 inhabitants - which is considered high. Among those younger than 15 years of age, there were 5.16 cases/100,000 inhabitants (high) and 0.89/100,000 inhabitants with degree II of physical disability (low); there were also many high-risk cases with an overall Moran index of 0.33 (p<0.001), active transmission (0.26; p<0.001), and subsequent diagnosis of the disease (0.12; p<0.006), as well as distribution in macro-region 1 and macro-region 4. CONCLUSION: There was a heterogeneous spatial distribution in the state, showing two overviews, the first being the presence of municipalities with high risk of disease transmission and the second with clusters of silent municipalities, reinforcing the character of leprosy neglect as a major public health problem. This study brings reflections for leprosy control actions, due to the identification of priority areas to combat this disease in Pernambuco.

Factors associated with severe forms and deaths from schistosomiasis and application of probabilistic linkage in databases, state of Pernambuco, Brazil, 2007-2017. / Fatores associados às formas graves e aos óbitos por esquistossomose e aplicação do linkage probabilístico nas bases de dados, Pernambuco, 2007­2017.

OBJECTIVE: To verify the agreement of data on severe forms and deaths from schistosomiasis recorded in the Brazilian Notifiable Diseases Information System and the Mortality Information System, sociodemographic variables with the occurrence of severe forms and deaths, and the temporal trend of the disease in the state of Pernambuco, Brazil. METHODS: This is an ecological, descriptive, time series study with data on severe forms and deaths from schistosomiasis in Pernambuco, from 2007 to 2017. For the linkage between databases, a function was developed in python programming language, using the Soundex method. To identify sociodemographic and health factors that correlated with the dependent variables, Pearson's correlation test was applied. For trend analysis, linear regression was applied. RESULTS: We identified 9,085 severe cases, 1,956 deaths, and 186 cases in the linkage. The correlation between the average positivity rate with the general water supply and waste collection was 0.22 and 0.26 respectively. We verified a correlation of the average cumulative mortality rate with water supply by well or spring (r=0.27), water supply by the general network (r=0.3), waste collection (r=0.42), and road urbanization (r=0.29). We found 3,153 severe forms in 2007 with a decrease trend and 205 deaths in 2010, without a trend pattern. CONCLUSION: There is a need for greater investments in disease control and in the quality of information, especially in the record of severe forms, considering that, due to the pathophysiology of the disease, death only occurs when the individual develops the chronic form, and its notification on the Notifiable Diseases Information System is imperative.

OBJETIVO: Verificar a concordância dos dados relacionados às formas graves e aos óbitos por esquistossomose registrados no Sistema de Informação de Agravos de Notificação e no Sistema de Informação Sobre Mortalidade, as variáveis sociodemográficas com a ocorrência das formas graves e óbitos e a tendência temporal da doença em Pernambuco. MÉTODOS: Trata-se de um estudo ecológico, descritivo, de série temporal com dados referentes às formas graves e aos óbitos por esquistossomose em Pernambuco, de 2007 a 2017. Para o linkage entre as bases de dados, foi desenvolvida uma função em linguagem python de programação, utilizando o método soundex. Para identificar fatores sociodemográficos e sanitários que se correlacionaram com as variáveis dependentes, foi aplicado o teste de correlação de Pearson. Para a análise de tendência, aplicou-se a regressão linear. RESULTADOS: Identificaram-se 9.085 casos graves, 1.956 óbitos e 186 casos no linkage. A correlação entre a taxa média de positividade com o abastecimento hídrico rede geral e coleta de lixo foi 0,22 e 0,26 respectivamente. Houve correlação da taxa média de mortalidade acumulada com abastecimento hídrico por poço ou nascente (r=0,27), abastecimento hídrico por rede geral (r=0,3), coleta de lixo (r=0,42), urbanização das vias (r=0,29). Ocorreram 3.153 formas graves em 2007, com tendência a redução, e 205 óbitos em 2010, sem um padrão de tendência. CONCLUSÃO: Há necessidade de maiores investimentos no controle da doença e na qualidade da informação, especialmente no registro das formas graves, pois, dada a fisiopatologia da doença, o óbito só ocorre quando o indivíduo desenvolve a forma crônica, sendo imperativo sua notificação no Sistema de Informação de Agravos de Notificação.

RESUMO Objetivo: Analisar os padrões espaciais da hanseníase em Pernambuco no período de 2011 a 2021. Métodos: Trata-se de um estudo epidemiológico ecológico, realizado com dados do Sistema de Informações de Agravos de Notificação com base nos casos novos de hanseníase em residentes de Pernambuco, entre 2011-2021. Foi realizada uma análise bayesiana empírica local e de dependência espacial com os índices de Moran global e local. Resultados: Foram registrados 25.008 casos novos de hanseníase com coeficiente médio anual de detecção de casos novos na população geral de 16,51 casos/100 mil habitantes — classificado como alto. Na população menor de 15 anos, ocorreu 5,16 casos/100 mil habitantes (muito alto) e 0,89/100 mil habitantes com grau II de incapacidade física (baixo) com aglomerados de alto risco para ocorrência com índice global de Moran de 0,33 (p<0,001), transmissão ativa (0,26; p<0,001) e diagnóstico tardio da doença (0,12; p<0,006), localizados na macrorregião 1 e na macrorregião 4. Conclusão: Houve uma distribuição espacial heterogênea no estado, evidenciando dois panoramas, o primeiro, a presença de municípios com alto risco de transmissão da doença e, o segundo, aglomerados de municípios silenciosos reforçando o caráter de negligência da hanseníase como grande problema de saúde pública. Este estudo traz reflexões para ações de controle da hanseníase, dada a identificação de áreas prioritárias para o enfrentamento dess/a doença em Pernambuco.

Infant mortality in a Brazilian Northeast State between 2009 and 2018: a temporal space approach / Mortalidade infantil em um estado do Nordeste Brasileiro entre os anos de 2009 e 2018: uma abordagem espaço temporal

Abstract Objective: to present the epidemiological profile of infant mortality and neonatal and post neonatal components, in addition to the temporal dynamics of these events in Pernambuco State between 2009 and 2018. Methods: descriptive, ecological, temporal space study of infant mortality in Pernambuco between 2009 and 2018. Epidemiological and temporal space characteristics were described using the Sistema de Informação sobre Mortalidade (Mortality Information System) and the Sistema de Informação sobre Nascidos vivos.(Information System on Live Births) as data sources. Results: there were 19,436 infant deaths in the period; 13,546 (69.7%) in the neonatal period and 5,890 (30.3%) in the post neonatal period. Male (55.4%), non-white children (74.7%) with low birth weight (63.5%) predominated; mothers were aged between 20 and 29 years (46.6%), with 8-11 years of schooling (43.9%) and preterm pregnancy (65.2%). Although the infant mortality rate decreased during the analyzed decade, high rates persisted in cities in the Sertão (backwoods) and Vale do São Francisco and Araripe macroregions of health services. Conclusions: even though infant mortality declined over the years studied, it is necessary to achieve better rates and confront inequalities and other obstacles that perpetuate the event in Pernambuco State.

Foram descritas características epidemiológicas e espaço temporais, tendo como fonte de dados o Sistema de Informação sobre Mortalidade e o Sistema de Informação sobre Nascidos vivos. Resultados: ocorreram 19.436 óbitos infantis no período, sendo 13.546 (69,7%) no período neonatal e 5.890 (30,3%) no período pós neonatal. Predominaram crianças do sexo masculino (55,4%), não brancas (74,7%), com baixo peso ao nascer (63,5%), sendo as mães com idade entre 20 e 29 anos (46,6%), com escolaridade entre oito e 11 anos (43,9%) e com gestação pré-termo (65,2%). Houve decréscimo da taxa de mortalidade infantil durante a década analisada, entretanto elevadas taxas persistiram em municípios das Macrorregiões de saúde Sertão e Vale do São Francisco e Araripe. Conclusões: a mortalidade infantil apresentou cenário de queda ao longo dos anos estudados, todavia é necessário o alcance de melhores taxas, o enfrentamento às desigualdades e a outros entraves que perpetuam o evento no estado de Pernambuco.

Analysis of the time series of pertussis in Brazil from 2010 to 2019 / Análise da série temporal da coqueluche no Brasil no período de 2010 a 2019

Abstract Objectives: to analyze a decade of spatio-temporal behavior of pertussis in Brazil and its epidemiological characteristics. Methods: ecological time series study of pertussis cases and deaths from the Notifable Diseases Information System in Brazil (2010-2019). The method of generalized linear analysis of Prais-Winsten and the Kernel analysis were used. Results: 32,849 cases were reported, of which 466 (1.42%) evolved to death, with a prevalence of 1.63/100,000 inhabitants and a mortality rate of 0.023/100,000 inhabitants. In the temporal analysis, the cyclical behavior of pertussis was evidenced, with trend variations in the period in 2014. Most cases occurred in children under 1 year of age (60.16%, p<0.01), sex female (55.28%, p=0.066) and white (48.42%, p=0.14). The largest share of deaths was in children aged <1 year (98.07, p<0.01), females (56.01%, p=0.066) and whites (43.78%, p=0.14). In the Kernel of prevalence, the South, Southeast and Northeast regions stood out with high density; while for mortality, the Southeast and Northeast stood out. Conclusions: the cyclical behavior of pertussis was observed, with a decreasing trend in recent years and the concentration of cases in children. This reinforces the importance of strengthening the population's immunization process.

Resumo Contexto: As violências autoprovocadas são caracterizadas por duas formas de autoagressão a suicida e a não suicida, com a busca do indivíduo pelas formas de agressão a si mesmo, sendo um comportamento intencional e agressivo à sua saúde. Objetivo: Analisar os dados de violências autoprovocadas nas regiões brasileiras, no período de 2009-2017 e discutir sobre esse problema no âmbito da saúde pública. Metodologia: Estudo epidemiológico transversal, descritivo, de abordagem quantitativa com as notificações do Sistema de Informação de Agravos e Notificações sobre violências autoprovocadas. Utilizaram-se o Software R e o Microsoft Excel para as análises estatísticas. Resultados: No Brasil a prevalência dos casos de violências autoprovocadas foi de 14,20/100 mil hab. (2009-2017) com a maior prevalência na região Sul, no sexo feminino, na faixa etária de 20-29 anos, com baixa escolaridade e raça/cor parda. A maioria dos casos ocorreram por envenenamento e na residência. Conclusão: O estudo identificou um cenário alarmante dos casos de violências autoprovocadas, principalmente, quando considerada as prevalências nas regiões Sul e Sudeste do Brasil, no público adulto jovem, população economicamente ativa. Tais achados servem para direcionar e subsidiar o planejamento de estratégias preventivas eficazes para a não realização do suicídio; podendo abranger desde a incorporação de ações como a restrição da comercialização de armas, a execução de campanhas de conscientização da população para identificar quais os fatores de risco associados com o comportamento não suicida e suicida e o auxílio aos indivíduos em situação de risco.

Abstract Context: Self-inflicted violence is characterized by two forms of self-harm, suicidal and non-suicidal, with the individual's search for forms of aggression against himself, being an intentional and aggressive behavior to his health. Objective: To analyze data on self-inflicted violence in Brazilian regions, in the period 2009-2017 and to discuss this problem in the context of public health. Methodology: A cross-sectional, descriptive epidemiological study, with a quantitative approach with notifications from the Diseases Information System and Notifications on self-inflicted violence. Software R and Microsoft Excel were used for statistical analysis. Results: In Brazil, the prevalence of cases of self-inflicted violence was 14.20 / 100 thousand inhabitants. (2009-2017) with the highest prevalence in the South, among females, aged 20-29 years, with low education and race / brown skin. Most of the cases occurred due to poisoning and in the residence. Conclusion: The study identified an alarming scenario of cases of self-inflicted violence, especially when considering the prevalence in the South and Southeast regions of Brazil, among young adults, economically active population. Such findings serve to guide and support the planning of effective preventive strategies for not carrying out suicide; it can range from the incorporation of actions such as the restriction of the commercialization of arms, the execution of awareness campaigns of the population to identify which risk factors are associated with non-suicidal and suicidal behavior and the assistance to individuals at risk

Lauric acid bilayer-functionalized iron oxide nanoparticles disrupt early development of freshwater snail Biomphalaria glabrata (Say, 1818).

Iron oxide nanoparticles (IONPs) have been indicated for the control of parasites and intermediate hosts, as well as applications in several sectors of nanomedicine. However, knowledge regarding its toxicity, mechanisms of action and the role of functionalization in gastropods that act as intermediate hosts of neglected disease parasites is still scarce. The present study aimed to evaluate the toxicity of lauric acid bilayer-functionalized IONPs (LA-IONPs), lauric acid isolated (LA) and iron ions in embryos and newly-hatched Biomphalaria glabrata. The snails were exposed to different concentrations of IONPs, LA and iron ions (1.0-97.65 mg L-1) during 144 h (embryos) and 96 h (newly-hatched) and multiple parameters were analyzed, such as mortality, hatching rate, developmental delay, and morphological changes. The results showed that both iron forms (LA-IONPs and iron ions) and LA promoted mortality, hatching inhibition and morphological changes in snail embryos in a concentration-dependent patterns. Embryos also showed iron bioaccumulation after exposure to both iron forms. High toxicity was observed in newly-hatched snails compared to embryos, indicating the protective role of ovigerous masses during the early developmental stages. LA induced high developmental toxicity compared to LA-IONPs and iron ions. Results showed the molluscicide activity of LA-IONPs and isolated LA, indicating their potential use as molluscicide in the snail control program.

PROPER-PRehabilitatiOn Plus Enhanced Recovery after surgery versus enhanced recovery after surgery in gynecologic oncology: a randomized clinical trial.

BACKGROUND: Prehabilitation is a process that occurs before surgery and aims to improve patient functional capacity and enhance surgical recovery. This process includes medical, nutritional, physical, and psychological interventions that may reduce the duration of hospital stay and provide postoperative physical benefits. PRIMARY OBJECTIVE: To evaluate the impact of a prehabilitation program on postoperative recovery time for patients who will undergo gynecological surgery following the Enhanced Recovery After Surgery (ERAS) guidelines. STUDY HYPOTHESIS: A multidisciplinary, preoperative prehabilitation program for patients who will undergo gynecological surgery leads to a reduction in the length of hospital stay and improves patient functional capacity. TRIAL DESIGN: Prospective, interventionist, and randomized controlled trial in a 1:1 ratio, open to multidisciplinary team and patients, blinded to surgeons and anesthesiologists. The control group will undergo ERAS standard preoperative care while the intervention group will have ERAS standard preoperative care plus prehabilitation. MAJOR INCLUSION CRITERIA: Patients scheduled to undergo gynecologic surgery performed by laparotomy with a preoperative schedule that allows prehabilitation intervention for 2 to 3 weeks. PRIMARY ENDPOINT: To compare time between surgery and the day the patient is ready for discharge in patients who underwent the prehabilitation process versus those who did not. Readiness for discharge is defined as the ability to take care of one's-self, to walk alone, and to ingest at least 75% of daily recommended calorie intake. SAMPLE SIZE: 194 participants ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: At present, 30 patients have been recruited. Accrual should be completed by 2023-24. TRIAL REGISTRATION: The study is approved by the IBCC - São Camilo Oncologia ethics committee (reference number 4.256.553) and is registered at clinicaltrials.gov (NCT04596800).

Spatial and temporal analysis of the human immunodeficiency virus in an area of social vulnerability in Northeast Brazil.

Human Immunodeficiency Virus (HIV) infection still represents an important public health problem, because it involves clinical, epidemiological, social, economic and political issues. We analyzed the temporal and spatial pattern of the HIV incidence in an area of social inequality in northeast Brazil and its association with socioeconomic indicators. An ecological study was carried out with a focus on all HIV cases reported in Alagoas State, Northeast Brazil from 2007 to 2016 using its 102 municipalities as the units of our analysis. Data from the Brazilian information systems were used. Georeferenced data were analyzed using TerraView 4.2.2 software, QGis 2.18.2 and GeoDa 1.14.0. Time trend analyses were performed by the Joinpoint Regression software and the spatial analyses included the empirical Bayesian model and Moran autocorrelation. Spatial regression was used to determine the influence of space on HIV incidence rate and socioeconomic inequalities. There was an increasing trend of HIV rates, especially in the municipalities of the interior. Significant spatial correlations were observed with the formation of clusters with emphasis on the coast of the state and in tourist regions. Spatial regression explained 46% of the dependent variable. The HIV incidence rate was positively influenced by rate of primary health care units (P=0.00), and negatively by Gini index (P=0.00) and proportion of heads of household without or low education (P=0.02). We conclude that the relationship found between indicators of better socioeconomic conditions and HIV infection suggests unequal access to the diagnosis of infection. Prevention and control strategies can be established according to each epidemiological reality.

Mapping the risk for transmission of urban schistosomiasis in the Brazilian Northeast.

This is an analysis of the risk of schistosomiasis transmission in the city of Recife in the Northeast of Brazil based on the number of schistosomiasis cases (Schistosoma mansoni) registered for the period 2007-2017 together with data resulting from active search of breeding sites of the Biomphalaria snail intermediate host. The analyses were performed using Kernel Density Estimation (KDE), SaTScan and Map Algebra methodology using human socio-demographic data and biotic and abiotic data from the snail breeding sites. Investigating 44 breeding sites resulted in a total of 3.800 snails, 31.8% of which were positive for S. mansoni DNA. These data were considered in relation to total of 652 schistosomiasis cases. The KDE showed two high-risk and two medium-risk clusters, while three significant clusters were identified by SaTScan. Combining these data with the Map Algebra methodology showed that all high-risk neighbourhoods had breeding sites with snails positive for S. mansoni. It was concluded that schistosomiasis transmission cannot be controlled without basic sanitation and sewage management in the presence of Biomphalaria snails. The technique of Map Algebra was found to be fundamental for the analysis and demonstration of areas with a high probability of schistosomiasis transmission.

Severe ischemic colitis following olanzapine use - A case report

Ischemic colitis is the most common subtype of intestinal ischemia usually resulting from vasospasm, vessel occlusion or mesenteric hypoperfusion. Neuroleptics have seldom been linked to ischemic colitis by blocking peripheral anticholinergic and antiserotonergic receptors inducing severe gastrointestinal paresis. We report a young patient with severe ischemic colitis requiring surgery due to necrosis of the bowel. After exclusion of other potential causes, olanzapine was admitted as the cause of ischemia. Clinicians should be aware of how to recognize and treat the potentially life-threatening effects of neuroleptics (AU)

Morbidity of mansoni schistosomiasis in Pernambuco-Brazil: Analysis on the temporal evolution of deaths, hospital admissions and severe clinical forms (1999-2014).

BACKGROUND: Current scientific information reported that due to successive treatments of schistosomiasis cases in endemic areas of Brazil in the last 30 years, there has been a decrease in severe clinical form (hepatosplenic) and mortality from upper gastrointestinal bleeding due to this disease. Against this information, literature data show that the state of Pernambuco presents significant percentage of deaths and hospitalizations due to schistosomiasis, and occurrence of severe clinical forms as schistosomiasis myeloradiculopathy and persistence of localities with high parasite loads. This scenario justified this research which seeking to update the morbidity and mortality of schistosomiasis in Pernambuco. OBJECTIVE: To conduct a temporal analysis on the evolution of deaths, hospital admissions and severe forms of Manson's schistosomiasis over the last 16 years in Pernambuco, Brazil. METHODS: It was performed a gathering secondary data on schistosomiasis, from healthcare information systems and from the records of Hospital das Clínicas, Federal University of Pernambuco (HC-UFPE), covering the period from 1999 to 2014. RESULTS: From 1999 to 2013 were registred 2578 deaths due to schistosomiasis and between 2008 and 2014 were recorded 473 hospitalizations for this disease. Among 1999-2014 were identified 1943 cases of schistosomiasis treated at the Hospital das Clínicas of Pernambuco. Among these cases, 72.6% (n. 1411) of the individuals presented the hepatosplenic clinical form (HE), 60.8% (n. 858) were at the age group 30-59 years (adults) and 58% were female. Among the HE cases, 4.6% (n. 58) had ascites, 43.2% (n. 556) had upper gastrointestinal bleeding and 39.1% (n. 489) had collateral circulation. The pattern of fibrosis in the liver E/EC (advanced fibrosis) and F/FC (very advanced fibrosis) occurred in 65.5% (n. 793) of cases. Between 1999-2014 the evolution curve of severe clinical forms of schistosomiasis remained stable, showing a tendency to decline from 2012. CONCLUSION: When compared to other states of Brazil, Pernambuco shows high numbers of deaths and hospital admissions due to schistosomiasis. The actions of the Schistosomiasis Control Program (PCE) have been developed in a disintegrated, disjointed and discontinuous way, which may explain the magnitude of deaths, hospitalizations and severe forms of the disease in Pernambuco, showing a lack of control and the maintenance of severe frame morbidity of schistosomiasis in this state.
