ABSTRACT

As hepatites virais, principalmente as causadas pelos vírus A, B e C, são muito prevalentes no mundo inteiro. As formas crônicas das hepatites B e C são as mais comuns no nosso meio e acarretam importantes conseqüências, tanto sociais quanto econômicas . Sendo assim, é importante que o clínico, independente de sua área, saiba diagnosticar e encaminhar pacientes infectados. Este artigo tem como objetivo revisar os algoritmos diagnósticos das hepatites e expor os tratamentos atualmente preconizados para as formas crônicas destas afecções (hepatites B e C).

ABSTRACT

Retrospective study in Clinicopathology of 66 surgical liver tissue from adult Thai patients admitted at Rajavithi Hospital, in Bangkok, during December 2002-September 2003 (10 month periods). The main purposes are: 1) To find the correlation of HBV, HCV with CH, LC, HCC. 2) To compare the correlation of Hepatocyte, AFP, CEA (IHC) in malignant cells, which one is the best usage to confirm the diagnosis of HCC in both primary and metastasis. 3) To review the clinicopathology of all these 66 liver samples. The results were significant correlation of HBsAg (serology) with HCC (p = 0.010), and also significant correlation of HBsAg (IHC in liver tissue) with CH, LC (p = 0.038, 0.021 respectively). Although no significant correlation (p > 0.05) of HCV (positive anti HCV) with CH, LC, HCC; the causes due to the small sample sizes and short period study are possibly bias factors. The authors concluded that Hepatocyte or Hep-Par I is the best immunocellular marker for malignant liver cells both in primary and metastasis (p < 0.001). The AFP, CEA show no correlation (p = 0.999, 0.670). The authors found other interesting non-viral related liver disease, common, uncommon, tumor and tumor-like (pseudotumor) lesions in the liver from the present study. The results of significant correlation of HBV (HBsAg) with CH, LC, HCC is one good evidence to further support The National HBV Vaccine Program for the uninfected population, which has been sponsored by the Thai Government, The Ministry of Public Health since 1992 and be one of the best and successful Thai Public-Health Policy.

ABSTRACT

El uso correcto de los métodos serológicos disponibles para el diagnóstico correcto de las Hepatitis Virales, nos permite evaluar su evolución, su seguimiento y aún su respuesta al tratamiento en el caso de Hepatitis Crónica como la Hepatitis B. Los conocidos paneles de diagnóstico de Hepatitis Viral, deben ser analizados en el contexto de la evaluación de cada caso clínico en particular. Siendo así debemos considerar que para la evaluación de un caso de hepatitis viral aguda, los marcadores serológicos que nos pueden ayudar a establecer la etiología de la misma en más del 80/100 de los casos, va dirigida a investigar la presencia de anticuerpos IgM contra el virus de la hepatitis A y el Anticore IgM de hepatitis B así como el HBsAg. No se requiere de rutina en la evaluación inicial la detección del virus de la hepatitis C...

ABSTRACT

AIMS: To evaluate clinicopathological spectrum of nonalcoholic steatohepatitis (NASH) METHODOLOGY: Total 210 patients with chronic liver disease were evaluated. Detailed history has taken with clinical examination, laboratory investigations, radiological findings and liver biopsy whenever possible. RESULTS: From 210 patients of chronic liver disease, 13 (6.19%) were diagnosed to have NASH (M:F = 9:4, age range 37-72 years, mean age 55.4 +/- 9 years). Of 13 patients, four were referred for asymptomatic enzyme elevation, nine had right hypochondriac pain. Risk factors were diabetes in four cases, obesity four, steroid treatment two and hyperlipidemia in three cases. Laboratory investigations showed abnormal liver enzymes in all the cases. Ultrasonography and CT scan was helpful in predicting fatty liver. Liver biopsy showed steatosis with inflammation in all, fibrosis in two and cirrhosis in one patient. CONCLUSION: NASH is an important form of chronic liver disease, and is characterised by hepatomegaly, elevated liver enzymes. It is essential to diagnose this condition due to its progression to liver fibrosis and cirrhosis in some patients.

ABSTRACT

La Asociación Chilena de Hepatología creó un registro de casos nuevos de hepatitis crónicas diagnosticadas con biopsia hepática entre los años 1994 y 1996. Se registran y clasifican de acuerdo a su etiología 106 pacientes altamente seleccionados con hepatitis crónica provenientes de la regiones metropolitana, quinta y segunda. De acuerdo a la etiología: 13 por ciento criptogénicas y 7 por ciento Virus B. La presencia de cirrosis al diagnóstico fue de 30 por ciento para las de origen viral C y 24 por ciento para las de origen autoinmune lo que podría afectar la respuesta a las alternativas terapéuticas. De acuerdo a estos resultados, deberíamos promover el diagnóstico más temprano en pacientes con alteraciones de laboratorio asintomáticas o notificando a los donantes de sangre en los que detecta alguna infección viral. En ausencia de otras instancias que realicen este tipo de evaluaciones, sugerimos repetir o mantener registros en lo posible de cobertura nacional, tanto para los pacientes con hepatitis crónica como para otras patologías hepáticas.

ABSTRACT

Entre el 70 por ciento de las causas de enfermedad crónica de los niños en América Latina, se deben a la atresia de vías biliares extrahepáticas (AVBEH) y a la colestasis intrahepática. La mayoría de los niños con AVBEH nacen con buen peso y pueden permanecer eutróficos si se les hace a tiempo una portoentero-anastomosis y reciben un apoyo nutricional adecuado; si esto no ocurre, alrededor de los 3 a 4 meses de edad, el niño ya presenta algún grado de desnutrición. La colestasis intra-hepática, al contrario de la AVBEH, es causa de retardo del crecimiento in útero. Otras patologías causales de hepatopatía crónica como: hepatitis, enfermedad metabólica, fibrosis quística, anomalías vasculares, malformaciones, toxicas y tumores, entre otras, también pueden producir déficit nutricional en el transcurso de los años. Las diferencias en la severidad del déficit nutricional se deben fundamentalmente a la etiología de la enfermedad hepática: los niños que sufren de colestasis intrahepática son los más afectados por los problemas de malabsorción de grasas, de ácidos grasos, de ácidos grasos esenciales y de vitaminas liposolubles. Aquellos con AVBEH con corrección quírurgica antes de 1 1/2 meses de vida, tienen por lo general menos alteraciones en el crecimiento. La hepatitis idiopática y la fibrosis congénita del hígado cursan sin modificacioes del estado nutricional. Estas patologías aparecen con menor frecuencia en el sexo femenino. La edad de inicio de la enfermedad también es importante, ya que los niños que adquieren la enfermedad en edades más tempranas presentan un mayor deterioro nutricional. Las alteraciones en los mecanismos de digestión y absorción de las grasas conducen a un déficit grave de vitaminas liposolubles y de ácidos grasos esenciales (AGE), con repercusión sobre el crecimiento, la peroxidación de lípidos celulares, los procesos de sintesis y reparación de tejidos, la respuesta inmunológica y los procesos inflamatorios. Todo lo anterior condiciona mayor susceptibilidad a las infecciones y en consecuencias más hospitalizaciones y deterioro de la calidad de vida. Los objetivos del soporte nutricional son: prevenir un deterioro hepático mayor, prevenir precozmente las complicaciones, vigilar y asegurar un crecimiento y desarrollo adecuado y garantizar mayor calidad de vida para el paciente y su familia

ABSTRACT

Con objeto de estudiar el comportamiento de los perfiles de glucosa e insulina en pacientes con hepatitis crónica por virus C (HCV), se incluyeron once pacientes con edad promedio de 47.5 años e índice de masa corporal de 23.8 por ciento 1.4. Cinco de ellos eran diabéticos. Su diabetes apareció años después de la hepatitis. El grupo control estuvo compuesto por 12 sujetos sanos con edad promedio de 42.8 años e índice de masa corporal de 24.1 ñ 1.2. Los pacientes tuvieron hepatitis crónica con diferentes grados de daño hepático, pero sin cirrosis. Las cifras de glucosa en ayunas fueron 119.9 ñ 43.4 mg/dL para el grupo de pacientes y 91.9 ñ 3.6 mg/dL para el control. Los niveles de insulina de ayunas fueron 28.1 ñ 17 µU/mL para el grupo de pacientes y 12.9 ñ 3.9 µU/mL para el control. Los valores posprandiales de insulina fueron 38.5 ñ 38 µU/mL para el grupo de pacientes y 51.04 ñ 27 µU/mL para el control. Los valores poprandiales de glucosa fueron 146.9 ñ 118 mg/dL para el grupo de pacientes y 104 ñ 15 mg/mL para el control. En cuanto a la glucosa y a la insulina, el grupo de pacientes no mostró diferencias significativas cuando sus valores de ayuno se compararon versus los posprandiales, contrario a lo que sucedió en el control (p < 0.01 y p< 0.005). Se sugiere que en pacientes con HCV se efectúen periódicamente mediciones de glucemia de ayuno y posprandiales para detectar oportunamente alteraciones de hiperglucemia

ABSTRACT

Eighteen patients with cirrhosis Child-Pough A, eight infected with hepatitis C virus, were studied. Urinary excretion of Ù aminolevulinic acid, porphobilinogen, coproporphyrins, uroporphyrins and fecal excretion of coproporphyrins and protoporphyrins were measured. Red blood cell protoporphyrin was also measured. There were no differences in the measured parameters between patients with or without hepatitis C virus infection. No patient had uroporphyrin excretion values over the normal range. Some patients had slight elevations in some parameters, but always below the values observed in porphyrias. In these group of patients, hepatitis C virus infection of its associated liver diasease do not cause detectable alterations in porphyrin metabolism

ABSTRACT

Chronic hepatitis and particularly viral hepatitis representes the most frequent indication for hepatic ponction biopsy. The increased frequency of this pathology has retriggered the interest of pathologists for new classifications. In this work, we insist on the interest of a precise morphological study of biopsical material and likewise the interest of a good classification for a better follow up of these patients the follow up compilsory because of the possible evolution towards the cirrhosis or even hepatocellular carcinoma

ABSTRACT

A case of an acute exacerbation of liver injury in a chronic HBV infected young male is reported. The correlation between the severe symptomatic hepatitis is done with the histopathologic findings of extense areas of bridging necrosis on the liver biopsy. The serological pattern for markers of HBV (Bhs Ag +, anti Hbs -, HBeAg -,antiHBe +, anti Hbc IgG + and IgM -) confirm a chronic infection, and the authors propose that the episode of severe hepatitis relates to the recent spontaneous seroconvertion of HbeAg to anti Hbe. Other causes of hepatitis were excluded, and the control liver biopsy (6 months later) showed normalization of hepatic architecture and absence of markers of viral replication in tissue and serum. A review of literature is done in an attempt do elucidate the diagnostic possibilities in this cases, with emphasis on new immunoassays useful in differentiating between acute hepatitis B and acute exacerbation of a chronic hepatitis by the same virus.

ABSTRACT

We performed a clinico-pathological study of 163 untreated cases of chronic hepatitis C. Eighty five percent of the patients were clinically asymptomatic and their physical examinations showed unremarkable or minimal changes at the time of the liver biopsy. Liver function tests tended to present slight abnormalities, involving mild elevations of the activity of the aminotransferases and gamma-glutamil transferase levels. In spite of these mild abnormalities, advanced chronic liver disease was histologically detected in eighty nine percent of the patients, mainly showing chronic active hepatitis. The most characteristic histological finding was an interlobular bile duct damage, which correlated with the presence of lymphoid aggregates in the portal tracts and with the development of fibrosis.

ABSTRACT

Introduçao. A hepatite crônica pelo vírus C apresenta tendência evolutiva para cirrose hepática e hepatocarcinoma. Tratamento, com drogas antivirais, está indicado numa tentativa de modificar a evoluçao da doença. Objetivo. Avaliar a resposta de pacientes com hepatite crônica ou cirrose pós-hepatite C ao tratamento com interferon alfa recombinante e identificar os fatores associados com boa resposta terapêutica. Métodos. Foram estudados 38 pacientes com hepatite crônica ativa ou cirrose pelo vírus C, tratados com 2,5 a 3,0MU de interfon três vezes por semana, por períodos de 6 a 12 meses. Considerou-se resposta completa e duradoura quando a ALT e AST se mantinham normais por período de seis meses após o término do tratamento, e resposta completa com recidiva naqueles em que houve elevaçao das enzimas após a suspensao da droga. Resultados. Houve normalizaçao da ALT e AST em 17 dos 38 pacientes (44,7 por cento). Deste grupo, 9/17 tiveram resposta completa e duradoura, e em 8/17 houve aumento das enzimas após a interrupçao do tratamento. Houve uma tendência de melhor resposta ao interferon nos pacientes jovens e naqueles com hepatite crônica ativa (ao invéz da cirrose). Os efeitos colaterais mais frequentes foram febre (80 por cento), mialgia (60 por cento), astenia (50 por cento), cefaléia (40 por cento) e artralgia (36 por cento). Conclusoes. O tratamento com interfon alfa recombinante mostrou resposta satisfatória e duradoura em 23 por cento dos casos, com melhor resultado em pacientes jovens e sem cirrose associada.

ABSTRACT

1. Immunocytochemical procedures have played an increasingly larger role in the identification of infectious disease agents in tissue sections owing to the increased availability and specificity of antibody reagents, the great sensitivity of the methods, and the relative facility with which the studies are performed. 2. Immunocytochemical methods can be applied to routine formalin-fixed tissue for the detection of infectious agents such as viruses, bacteria, fungi, and protozoa among other microorganisms for diagnostic and research purposes

ABSTRACT

Ainda sao raros os casos de infeccao por hepatite C (HCV)na regiao central do Brasil. Neste estudo, 2.350 doadores voluntarios de sangue foram avaliados, resultando em prevalencias para o anti-HCV de 2,2 (por cento), pelo ELISA de segunda geracao, e de 1,4 por cento, apos o ensaio confirmatorio "line immunoassay". Anticorpos contra os antigenos "core", NS4 e NS5 do HCV foi observada em 76,6 (por cento) dos doadores anti-HCV positivos. A positividade da reacao em cadeia da polimerase (PCR) mostrou-se relacionada a reatividade aos diferentes antigenos do HCV no "line immunoassay". A maioria dos doadores positivos tiveram historia previa de exposicao parenteral. A combinacao de ALT>50 UI/1 e positividade ao anti-HBc parece nao ser eficaz como marcadores indiretos para a infeccao pelo HCV, entretanto a dosagem do ALT e a deteccao de anti-HCV sao indicadas na triagem de doadores de sangue brasileiros.
