Hepatitis virus and hepatocellular carcinoma in Brazil: a report from the State of Espírito Santo

Introduction Few studies have examined hepatocellular carcinoma (HCC) in Brazil, and the incidence and risk factors for this type of malignancy vary greatly geographically. In this paper, we report several risk factors associated with HCC diagnosed at the University Hospital in Vitória, ES, Brazil. Methods We reviewed 274 cases of HCC (January 1993 to December 2011) in which hepatitis B (HBV) and C (HCV) virus infection and chronic alcoholism were investigated. A diagnosis of hepatocellular carcinoma was confirmed by histology or by the presence of a characteristic pattern on imaging. Results HCC with associated liver cirrhosis was noted in 85.4% of cases. The mean ages of men and women were 56.6 years and 57.5 years, respectively. The male-to-female ratio was 5.8:1. Associated risk factors included the following: HBV, 37.6% (alone, 23.4%; associated with chronic alcoholism, 14.2%); HCV, 22.6% (alone, 13.5%; associated with chronic alcoholism, 9.1%), chronic alcoholism, 17.1%, non-alcoholic steatohepatitis, 2.6% and cryptogenic, 19.3%. The male-to-female ratio was higher in cases associated with HBV or chronic alcoholism compared with HCV-associated or cryptogenic cases. In 40 cases without associated cirrhosis, the male-to-female ratio and mean age were lower than those in cirrhosis-associated cases. Conclusions These results demonstrate that the main risk factor associated with HCC in the State of Espírito Santo is HBV. Chronic alcoholism is an important etiological factor, alone or in association with HBV or HCV infection. .

Etiology of liver cirrhosis in Brazil: chronic alcoholism and hepatitis viruses in liver cirrhosis diagnosed in the state of Espfrito Santo

OBJECTIVES: To report the etiology of liver cirrhosis cases diagnosed at the University Hospital in Vitoria, Espirito Santo, Brazil. METHODS: The medical charts of patients with liver cirrhosis who presented to the University Hospital in Vitoria were reviewed. Chronic alcoholism and the presence of hepatitis B or C infections (HBV and HCV, respectively) were pursued in all cases. RESULTS: The sample consisted of 1,516 cases (male:female ratio 3.5:1, aged 53.2±12.6 years). The following main etiological factors were observed: chronic alcoholism alone (39.7%), chronic alcoholism in association with HBV or HCV (16.1 %), HCV alone (14.5%) and in association with alcoholism (8.6%) (total, 23.1 %), and HBV alone (13.1%) and in association with alcoholism (7.5%, total 20.6%). The remaining etiologies included cryptogenic cases (9.8%) and other causes (6.0%). The mean patient age was lower and the male-to-female ratio was higher in the cirrhosis cases that were associated with alcoholism or HBV compared with other causes. Intravenous drug abuse and a history of surgery or blood transfusion were significantly associated with HCV infection. Hepatocellular carcinoma was present at the time of diagnosis in 15.4% of cases. Chronic alcoholism associated with HCV infection was significantly associated (p<0.001) with reduced age (at the time of cirrhosis diagnosis) and increased prevalence of hepatocellular carcinoma (p = 0.052). CONCLUSION: Alcoholism, HCV and HBV are the main factors associated with liver cirrhosis in the state of Espirito Santo. Chronic alcoholism associated with HCV infection reduced the age of patients at the time of liver cirrhosis diagnosis.

Tipologia de Lesch em alcoolistas no Brasil / Lesch's Typology in Brazilian alcoholic patients

OBJETIVOS: Alcoolismo é uma doença heterogênea, com apresentações clínicas, resultados terapêuticos e recaídas variáveis, indicando vulnerabilidades biológicas diferentes. A Tipologia de Lesch distingue quatro categorias de alcoolismo: Tipo I - graves sintomas de abstinência; Tipo II - álcool como solução para conflitos; Tipo III - álcool para "tratamento" de desordens psiquiátricas; Tipo IV - alterações neurológicas antes do uso de álcool. Este estudo verificou a aplicabilidade de uma classificação do tipo clínico de alcoolismo pela Tipologia de Lesch em um ambulatório público brasileiro de atendimento especializado de alta demanda. MÉTODO: Estudo seccional descritivo, que classificou pacientes do ambulatório de alcoolismo do Hospital Universitário da Universidade Federal do Espírito Santo de acordo com a Tipologia de Lesch. RESULTADOS: A diferenciação pela Tipologia de Lesch foi facilmente conduzida em um serviço ambulatorial público de alta demanda. De 170 pacientes, 21,2 por cento foram classificados como Tipo I; 29,4 por cento, Tipo II; 28,8 por cento, Tipo III e 20,6 por cento, Tipo IV. Embora os diferentes tipos de alcoolismo tenham diferentes apresentações clínicas, o padrão de ingestão alcoólica, idade da primeira ingestão e tempo de abstinência não diferiram entre os tipos de alcoolismo. CONCLUSÃO: A distinção do tipo clínico de alcoolismo de acordo com a Tipologia de Lesch foi considerada aplicável em um ambulatório público brasileiro de grande demanda, sendo os dados encontrados semelhantes aos relatados em estudos realizados em diferentes países. A aplicação dessa classificação poderá definir mudanças nas estratégias de enfrentamento individualizadas do alcoolismo, sendo, entretanto, necessários estudos de seguimento para avaliar os resultados terapêuticos das mesmas.

OBJECTIVE: Alcohol dependence is a heterogeneous disease with a clear variability in clinical, therapeutic results and relapses, indicating different biological vulnerability. Lesch et al (1988) distinguished four categories of alcohol dependence: Type I - severe symptoms of abstinence; Type II - alcohol as a solution for conflicts; Type III - alcohol as self-medication for psychiatric symptoms; Type IV - history of neurological lesions preceding the development of alcohol dependence. This study examined the applicability of a classification of the clinical type of alcoholism according to Lesch's Typology in a high demanding Brazilian public outpatient service for alcohol dependence. METHOD: Alcoholics from a Brazilian public outpatient service for treatment of alcoholism of the School of Medicine of the Federal University of Espírito Santo were classified into categories according to Lesch's Typology. RESULTS: Differentiation by Lesch's Typology was easily conducted in a high demanding public outpatient service. Of 170 alcoholics, 21.2 percent were classified as Type I; 29.4 percent, Type II; 28.8 percent, Type III; 20.6 percent, Type IV. Although different types of alcoholism have different clinical presentations, patients showed similar pattern of alcohol intake, age for the first use of alcohol and withdrawal. CONCLUSION: Distinguishing clinical types of alcohol dependence according to Lesch's Typology was considered applicable in a high demanding Brazilian public outpatient service, in which the results were similar to those reported in studies realized in other countries. The application of this classification may provide significant changes in strategies for individualized approaches that may be of a great importance in the treatment of alcohol dependence. However, the therapeutic results of these changes will need to be evaluated in follow-up studies.

Pancreatite crônica: resultados do tratamento cirúrgico em 74 pacientes / Results of the surgical management of 74 patients with Chronic pancreatitis

OBJETIVO: Analisar as indicações, técnicas e resultados do tratamento cirúrgico de 74 pacientes operados por complicações da pancreatite crônica. MÉTODO: Foram pacientes consecutivos, estudados prospectivamente pelo preenchimento de um protocolo individual, no período de 1971 a 2000. Foram realizadas cirurgias de derivação e ressecção. O acompanhamento foi feito pelo agendamento de consultas no ambulatório, por convocação por cartas e telefonemas. RESULTADOS: Dos 270 pacientes com pancreatite crônica, acompanhados pelo Serviço, 74 (27,4 por cento) foram operados. Destes 74 pacientes, 97,7 por cento eram do sexo masculino e a idade variou de 15 a 63 anos, com média de 39,4 anos para alcoolistas e 33,1 para aqueles com outras etiologias. O alcoolismo foi a causa da doença em 68 pacientes (90,5 por cento) e os outros casos estiveram relacionados a hiperparatiroidismo(1), pancreatite hereditária (1), fibrose retroperitoneal (1) e em três casos a etiologia não foi definida. As seguintes causas únicas ou associadas definiram a indicação cirúrgica:1. dor em 44,6 por cento dos pacientes; 2. compressão de vias biliares em 28,4 por cento; 3. pseudocistos em 12,2 por cento; 4. fístulas internas em 10,8 por cento. Cinqüenta pacientes (67,5 por cento) foram submetidos a operações de derivação e 24 (32,5 por cento) a cirurgias de ressecção. Oito pacientes derivados (16,0 por cento) complicaram, ocorrendo três óbitos; dez ressecados (41,6 por cento) complicaram, com cinco óbitos. Os óbitos estiveram relacionados a abscessos, às deiscências e às hemorragias cirúrgicas. CONCLUSÕES: As cirurgias de derivação mostraram-se mais seguras e as complicações que evoluíram com infecção foram as mais graves e ocorreram com mais freqüência nas ressecções.

BACKGROUND: To evaluate the indications, methods and results of the surgical treatment of 74 patients operated on for chronic pancreatitis complications. METHOD: Consecutive patients' charts were studied prospectively, during the years of 1971 to 2000. Surgery was indicated for pain, billiary tract stricture, pseudocysts, pancreatic ascitis and pancreaticopleural fistulas. Pancreaticojejunal anastomosis, billiary tract derivations and resections were performed. Follow-up was achieved through ambulatorial appointments or by mail and telephone calls. RESULTS: Of 270 patients listed with chronic pancreatitis, 74 (27.4 percent) were operated on. 97.7 percent of them were males. Patients varied in age from 15 to 63 years old, with an average of 39.4 years for alchoolists and 33.1years for those with pancreatitis of other etiologies. The disease was caused by alchool in 68 patients (90.5 percent). The other causes were: hyperparathyroidism (1), hereditary pancratitis (1), retroperitoneal fibrosis(1) and in three patients the etiology was unknown. Indications for surgery were: 1. Pain in 44.6 percent of the patients; 2. Billiary tract stricture (28.4 percent); 3.Pseudocysts (12.2 percent); 4. Pancreatic ascitis and pancreaticopleural fistulas (10.8 percent). Derivations were performed in 50 patients (67.5 percent), and resections in 24 (32.5 percent). Complications ocurred in eight patients with five hospital deaths related to abscesses, suture leaking and surgical bleeding. CONCLUSIONS: There was less morbidity and mortality for derivations and than after resections.
