Caracterización epidemiológica de pacientes con cirrosis en una consulta de gastroenterologia en Pereira, Colombia, 2009-2012 / Epidemiologic characterization of the patients with cirrhosis treated in an outpatient clinic of gastroenterology in Pereira, Colombia, 2009-2012

Este estudio soporta sus bases en la necesidad de obtener datos claros que correspondan a la realidad de la población de la zona centro occidental de nuestro país, con el fin de aclarar el panorama con respecto a la cirrosis, condición asociada a múltiples factores que influyen, tanto en su origen y evolución, como en su pronóstico. Para ello realizamos un estudio descriptivo de cien pacientes con diagnóstico de cirrosis que consultaron al servicio de gastroenterología durante el período comprendido entre enero de 2009 hasta julio de 2012. Para un mejor análisis, el estudio se desarrolló conformando categorías epidemiológicas, etiológicas, de descompensación, de pronóstico y de muerte. La información se recolectó directamente de las historias clínicas de los pacientes y se completó con entrevistas, diligenciando un instrumento en el cual se reunían las variables necesarias para el análisis. A los pacientes que carecían de algunos datos imagenológicos se les realizaron estudios de extensión como ecografía hepática y doppler portal. Luego de la recolección de los datos, se realizó una descripción detallada de las variables propuestas encontrando algunas con mayor significancia estadística, las cuales se llevaron a análisis bivariado y multivariado. Se encontró una gran diversidad en esta población; la mayoría de los pacientes procedían de áreas urbanas; la relación de género fue 1:1. El alcohol fue el principal factor etiológico para el desarrollo de esta patología, lo cual concuerda con otros países Latinoamericanos. La causa autoinmune viene en incremento, acá ocupó un segundo puesto, seguida de la etiología viral.

The following research supports its bases in the necessity of dependable epidemiological data corresponding to population reality in the western center region of our country, in order to clarify the public health outlook for cirrhosis, understanding it as an associated condition with multiple influencing factors, both in its origin and its development, as well as in its prognosis. For this research we carry out a descriptive study with one hundred patients diagnosed with cirrhosis who consulted for a gastroenterology service in a period from January 2009 to July 2012. For a better analysis, the research was developed by creating the following categories: Epidemiological, etiological, by decompensation, by prognosis, and by death. The information was directly gathered from patient’s medical records and completed with interviews, in that way we earn an instrument which gathered the needed variables for analysis. Extension studies like hepatic ultrasound and portal Doppler were realized to patients without some imagenological information. After data garner, a detailed description of previously variables was performed, finding some of them with higher statistical significance, which were analyzed by a bivariate and multivariate system. A great variety was found in this population; most of patients came from urban areas; the relation in gender was 1:1. Consumption of alcohol was the main etiological factor to develop this pathology. Previous information matched with described data from other Latin-American countries. Autoimmune cause should be taken into account because is increasing and occupied a second place in the research, followed by infectious viral etiology.

Alterações iniciais da fibrose septal por Capillaria Hepatica (Bancroft, 1893) em ratos / Initial changes of septal fibrosis Capillaria hepatica (Bancroft, 1893) in rats

espaço-porta é o local de origem da fibrose em muitas doenças crônicas hepáticas. Essa área do fígado participa da drenagem linfática hepática e abriga diversos elementos celulares potencialmente fibrogênicos. Estudos sobre a fibrose hepática relacionados à infecção experimental de ratos pelo helminto Capillaria hepatica têm demonstrado que a fibrose começa em áreas portais com a distribuição de septos que sulcam o parênquima hepático se desenvolvendo em áreas próximas ao espaço de Disse. Entretanto, apesar de esta fibrose ocorrer de forma paralela aos sinusóides, estudos têm revelado que não apenas as células estreladas hepáticas participam da fibrose septal, mas também outros tipos celulares residentes nos espaços-porta. Diante destes aspectos, o presente estudo desenvolveu-se com o intuito de investigar a contribuição das células potencialmente fibrogênicas dos espaços-porta, nas fases iniciais da infecção, onde a fibrose se concentra. Para isso, foram utilizados fragmentos de fígado, em blocos parafinados, disponíveis nos arquivos do Laboratório de Patologia Experimental (CPqGM/Fiocruz) provenientes de ratos infectados com 800 ovos de Capillaria hepatica e foi possível observar que ocorreu a proliferação de colangiócitos e a concentração de miofibroblastos em áreas portais, além da ativação de células estreladas hepáticas, sendo todos os resultados vistos por meio da coloração de rotina HE, Picro-sírius vermelho e imunohistoquímica para α-actina de músculo liso, CD31 e GFAP.

Portal space is the local of origin for fibrosis in many chronic liver diseases. This area is involved with lymph drainage and contains several cell types, potentially fibrogenic. Experimental studies related to hepatic fibrosis during Capillaria hepatica infection in rats have suggested that the septal fibrosis indeed takes origin from portal spaces, with the distribution of the septs in the parenchymal region in proximity areas of Disse space. However, despite this fibrosis occurs in parallel to sinusoids, studies have revealed that not only the hepatic stellate cells participate in septal fibrosis, but also other resident cell types in the portal spaces. In face these aspects, the goal of present study was investigate the contribution of the cells potentially fibrogenic in the portal space, in the early phases of the infection. For this, blocks in paraffin available of the liver of rats infected with 800 eggs of Capillaria hepatica archived in the Laboratory of Experimental Pathology (Research Center Gonçalo Moniz, Fiocruz - BA), were utilized and it was observed that proliferation of colangiocytes and concentration of myofibroblasts occurred portal areas, in addition to the activation of hepatic stellate cells. All results were analised by routine staining HE, Sirius red and immunohistochemistry for α-SMA, GFAP and CD31.

Análise dos escores de gravidade como preditores na mortalidade em cirróticos hospitalizados / Evaluation of the prognostic scores to predict mortality in hospitalized cirrhotic patient

Introdução: Diversos índices têm sido propostos na avaliação da gravidade da doença hepática. Objetivo: Analisar os escores de Child-Turcote- Pugh (CTP), APACHE II, MELD e SOFA como índices prognósticos de mortalidade hospitalar em pacientes cirróticos. Metodologia: Foram avaliados prospectivamente todos os cirróticos que se internaram em enfermaria provenientes da emergência de um Hosputal Geral de Porto Alegre, em um período de 6 meses. Os escores CTP, MELD, APACHE II e SOFA foram registrados, bem como o desfecho (alta ou óbito). O nível de significância adotado foi de 5%. Resultados: Foram avaliados 61 cirróticos. Quarenta e três eram homens (70%). A média de idade foi de 54,7±11,7 anos. Álcool e/ou o vírus da hepatite C (HCV) foram responsáveis pela etiologia de 50 (82%) casos. Quanto ao CTP, houve 7 (32%) mortes naqueles CTP A ou B, e 11 (38%) naqueles C (p=0,27). A mediana do escore MELD foi de 15, sendo que houve 3 (11%) mortes naqueles com MELD < 15 e 15 (45%) naqueles com MELD ≥15 (p=0,02). A mediana do escore APACHE II foi de 9, sendo que houve 0 morte naqueles com índice < 9 e 18 (41%) naqueles com índice ≥9 (p<00,1). Em relação ao SOFA, a média foi de 3,6±1,8 naqueles vivos versus 5,6±2,6 naqueles que foram a óbito durante a internação (p=0,005). A mortalidade hospitalar foi de 29% (18 casos). Conclusões: Os escores MELD, APACHE II e SOFA se mostraram bons preditores de mortalidade em cirróticos hospitalizados, mas não a classificação de CTP.

Introduction: A number of indexes have historically been proposed to assess the severity of liver disease. Aim: To evaluate the Child-Turcote-Pugh (CTP), APACHE II, MELD and SOFA scores as prognostic indexes of in-hospital mortality among cirrhotic patients. Methods: This is a prospective analysis of all cirrhotic patients who were admitted to a general hospital of Porto Alegre in a period of 6 months. CTP, MELD, APACHE II and SOFA scores were analyzed, as well as the outcome (discharge or death). The level of significance was 5%. Results: A total of 61 cirrhotic patients were evaluated. Forty-three patients were males (70%) and the mean age was 54.7±11.7 years. Alcohol and/or hepatitis C virus (HCV) were the ethiological agents in 50 (82%) cases. Concerning CTP scores, there were 7 (32%) deaths among CTP A or B and 11 (38%) deaths among CTP C (p=0.27). The median for the MELD scores was 15, and there were 3 (11%) deaths among those with MELD < 15 and 15 (45%) deaths among those with MELD ≥15 (p=0.02). The median for the APACHE II scores was 9, and there were no deaths (0) among patients with indexes ≥9 (p<00.1). Concerning the SOFA, the mean was 3.6±1.8 among living patients versus 5.6±2.6 among those who progressed to death during the hospitalization (p=0.005). The overall in-hospital mortality rate was 29% (18 cases). Conclusions: MELD, APACHE II, and SOFA scores proved to be good predictors of mortality of hospitalized cirrhotic patients, but the CTP did not.

Denture-related hyperplasia: a clinical study of a turkish population group

Inflammatory fibrous hyperplasia (epulis fissuratum) (IFH) and inflammatory papillary hyperplasia (IPH) are oral mucosal diseases caused by ill-fitting denture wearing. A study was carried out on a group of Turkish people consisted of 131 female and 39 male complete denture wearers (n= 170) distributed in two age groups (30-60 and 60-80 years old). The analysis of data collected from patients showed that while the incidence of IFH was higher in women than in men, the incidence of IPH was similar. Most lesions were found in the 30-60 year-old group. The incidence of lesions increased as the denture wearing period increased. Soft tissue growth was the main complaint of the patients with IFH and IPH. In the maxilla, the incidence of IFH was higher than IPH. There was also a significant difference between the distribution of the lesion types in the jaws. There were a larger number of lesions in the maxilla compared to the mandible and most IFH lesions were located in the anterior region of the jaws.

A hiperplasia fibrosa inflamatória (epulis fissuratum) (HFI) e a hiperplasia papilar inflamatória (HPI) são doenças da mucosa causadas por próteses mal-ajustadas. Foi feito um estudo num grupo de pessoas, na Turquia, composto por 131 mulheres e 39 homens (n=170) usuários de próteses totais. O grupo foi subdividido em duas faixas etárias (30 a 60 e 60 a 80 anos). A análise dos dados coletados dos pacientes mostrou que a incidência de HFI foi mais alta entre as mulheres, ao passo que a incidência de HPI foi similar em ambos os sexos. A maioria das lesões foi encontrada no grupo indivíduos de 30 a 60 anos. A incidência das lesões aumentou com o tempo de uso da prótese. A queixa principal dos pacientes com HFI e HPI foi o aparecimento de tecidos moles. A incidência de HFI foi maior do que HPI, na maxila. Houve também diferença significativa de distribuição dos tipos de lesão nos maxilares. Houve maior número de lesões na maxila, em comparação com a mandíbula e a maioria das lesões HFI estava localizada na parte anterior dos maxilares.

[Epidemiological, etiological and evolutionary aspects of children cirrhosis in a develping country: Experience of the pediatric department of SFAX University hospital, Tunisia]

Cirrhosis is rare in pediatrics. The children cirrhosis is particular by the ascendancy of biliairy cirrhosis and cirrhosis due to an innate error of metabolism and by the relative frequency of the cases where an etiological treatment is possible. However in developing countries, the children cirrhosis still put problems of etiological diagnosis and of therapeutic coverage. To study epidemiological and etiological particularities, therapeutic modalities and outcome of cirrhosis in the sooth of Tunisia. We led a retrospective study over 15 years [1990-2004] having allowed to depict 71 cirrhotic children followed in the service of general pediatric department of SFAX University hospital [Tunisia]. Our patients divide up into 36 girls and 35 boys. The age of revelation of the disease was variable [15 days to 15 years]. Jaundice and hepatomegaly were the most two clinical signs frequently found in the clinical exam. On the etiological plan, biliairy cirrhosis [Extra hepatic biliary atresia, dilatation of choledocal cyst, progressive familial intrahepatic cholestasis...] were the most frequent [40%] followed by metabolic cirrhosis[tyrosinemia type I, Wilson disease...] [17%] and post-hepatitic cirrhosis [17%]. In 27%of cases, no etiology was found. Besides the symptomatic treatment, an etiological treatment was tempted in some cases. No patient benefited from hepatic transplantation. The follow-op of the children cirrhosis was grave becaose 30 children [42%] died, 19 children are lost-sight and 22 children [31%] are still alive. The children cirrhosis pose still in our country of the problem of etiological diagnosis because of the not availability of some specific additional exams and especially problems of coverage for lack of a program of hepatic transplantation
