RESUMO

ABSTRACT Background: To analyze the effectiveness and the safety of Sofosbuvir-based regimens to treat patients with chronic hepatitis C virus (HCV) infection and chronic kidney disease (CKD). Methods: A retrospective, observational study in patients with chronic HCV infection and CKD treated with Sofosbuvir-based regimens was performed. Liver fibrosis, comorbidities, HCV genotype and sustained virological resposnse (SVR) at 12th week post-treatment were evaluated. Kidney function was accessed by serum creatinine and glomerular filtration rate (GFR). The assumed level of significance was 5 %. Results: Thirty-five patients were treated. The mean age was 52.1 ± 10.9 years, 19 (54.3 %) were women, 32 (91.4 %) were already kidney transplanted and 3 (8.6 %) were on hemodialysis. The SVR by intention to treat was 88.6 %. The mean GFR was 65.8 ± 28.6 and 63.7 ± 28.3 ml/min pre- and post-treatment respectively (p > 0.05). Treatment was interrupted in 1 (2.85 %) patient due to anemia and in 2 (5.7 %) due to loss of kidney function. Conclusion: Sofosbuvir-based regimens are effective to treat HCV in patients with CKD. In patients with mild CKD this type of therapy seems to be safe.

RESUMO

ABSTRACT BACKGROUND: Chronic hepatitis C (CHC) can progress to cirrhosis and its complications as hepatocellular carcinoma, leading to morbidity and mortality. To know the profile of patients with CHC virus is fundamental to optimize management. OBJECTIVE: To describe the profile of patients with CHC in a public health program in Southern Brazil. METHODS: A retrospective study was carried out in patients with CHC who underwent treatment against hepatitis C virus in a dispensation and pharmaceutical assistance center of the Public Health Department of the State of Rio Grande do Sul, South Brazil. All medical records of patients attended between December/2015 and December/2016 were evaluated. RESULTS: A total of 1,431 records of patients with CHC were evaluated. Males were the most prevalent (802; 56%) patients. The mean age was 58.6±9.9 years, ranging from 18 to 89 years. Genotype 1 was the most frequent (866;60.5%) of the patients. Ninety (6.3%) patients were transplanted from a solid organ, and of these, 73 (5.1%) were transplanted from the liver. The fibrosis evaluation was performed in 1,300 (90.8%) patients. Of these, 566 (39.6%) were evaluated through liver biopsy. Regarding the degree of fibrosis, 779 (54.4%) presented fibrosis grade 4 (cirrhosis). The genotype 3 was the most associated with fibrosis grade 4, and genotype 1 was associated with high viral load. CONCLUSION: The present study made possible the evaluation of the characteristics of patients with CHC in a public health program in South Brazil. There was a predominance of CHC in males, and the mean age was 59 years. They presented a predominance of genotype 1, higher viral load in patients with genotype 1 and greater degree of fibrosis in patients with genotype 3.


RESUMO CONTEXTO: A hepatite crônica C (HCC) pode evoluir para cirrose e suas complicações como carcinoma hepatocelular, acarretando morbimortalidade. Conhecer o perfil dos pacientes portadores do vírus da HCC é fundamental para o melhor manejo do tratamento. OBJETIVO: Descrever o perfil dos pacientes portadores de HCC em um programa de saúde pública do sul do Brasil. MÉTODOS: Foi realizado um estudo retrospectivo onde foram incluídos os pacientes com HCC que realizaram o tratamento contra o vírus C em um polo de dispensação e assistência farmacêutica da Secretaria Estadual da Saúde do Estado do Rio Grande do Sul, Brasil. Foram avaliados todos os prontuários dos pacientes tratados entre dezembro/2015 e dezembro/2016. RESULTADOS: Foram avaliados 1.431 registros de pacientes portadores de HCC. O sexo masculino foi o mais prevalente (802; 56%) pacientes. A idade média dos pacientes foi de 58,6±9,9 anos, com variação de 18 a 89 anos. O genótipo 1 foi o mais frequente, em 866 (60,5%) dos pacientes. Noventa (6,3%) pacientes eram transplantados de órgão sólido, sendo que 73 (5,1%) eram transplantados de fígado. A avaliação de fibrose foi realizada em 1.300 (90,8%) pacientes. Dentre estes, 566 (39,6%) foram avaliados através de biópsia hepática. Em relação ao grau de fibrose, 779 (54,4%) apresentavam fibrose grau 4 (cirrose). Os genótipos foram analisados em relação aos diferentes graus de fibrose, sendo observado que o genótipo 3 está associado com o grau 4 de fibrose. O genótipo 1 está associado com alta carga viral. CONCLUSÃO: O presente estudo possibilitou a avaliação do perfil dos pacientes portadores de HCC em um programa de saúde pública do Brasil. Houve uma predominância de HCC no sexo masculino, e a média de idade foi de 59 anos. Apresentam um predomínio do genótipo 1, maior carga viral nos pacientes portadores do genótipo 1 e maior grau de fibrose nos portadores de genótipo 3.

RESUMO

BACKGROUND: Spontaneous bacterial peritonitis is a serious complication in cirrhotic patients, and changes in the microbiological characteristics reported in the last years are impacting the choice of antibiotic used for treatment. OBJECTIVE: The aim of the present study is to evaluate the changes in the epidemiology and bacterial resistance of the germs causing spontaneous bacterial peritonitis over three different periods over 17 years. METHODS: All cirrhotic patients with spontaneous bacterial peritonitis and positive culture of ascites fluid were retrospectively studied in a reference Hospital in Southern Brazil. Three periods were ramdomly evaluated: 1997-1998, 2002-2003 and 2014-2015. The most frequent infecting organisms and the sensitivity in vitro to antibiotics were registered. RESULTS: In the first period (1997-1998) there were 33 cases, the most common were: E. coli in 13 (36.11%), Staphylococcus coagulase-negative in 6 (16.66%), K. pneumoniae in 5 (13.88%), S. aureus in 4 (11.11%) and S. faecalis in 3 (8.33%). In the second period (2002-2003), there were 43 cases, the most frequent were: Staphylococus coagulase-negative in 16 (35.55%), S. aureus in 8 (17.77%), E. coli in 7 (15.55%) and K. pneumoniae in 3 (6.66%). In the third period (2014-2015) there were 58 cases (seven with two bacteria), the most frequent were: E. coli in 15 (23.1%), S. viridans in 12 (18.5%), K. pneumoniae in 10 (15.4%) and E. faecium 5 (7.7%). No one was using antibiotic prophylaxis. Considering all staphylococci, the prevalence increased to rates of the order of 50% in the second period, with a reduction in the third period evaluated. Likewise, the prevalence of resistant E. coli increased, reaching 14%. CONCLUSION: There was a modification of the bacterial population causing spontaneous bacterial peritonitis, with high frequency of gram-positive organisms, as well as an increase in the resistance to the traditionally recommended antibiotics. This study suggests a probable imminent inclusion of a drug against gram-positive organisms in the empiric treatment of spontaneous bacterial peritonitis.

RESUMO CONTEXTO: A peritonite bacteriana espontânea é uma complicação séria em pacientes cirróticos e as alterações nas características microbiológicas relatadas nos últimos anos podem afetar a escolha do antibiótico utilizado no tratamento. OBJETIVO: Os objetivos do presente estudo são avaliar as mudanças na epidemiologia e perfil de resistência bacteriana dos germes causadores de peritonite bacteriana espontânea em três períodos diferentes ao longo de 17 anos. MÉTODOS: Todos os pacientes cirróticos com peritonite bacteriana espontânea e cultura positiva de fluido ascítico foram estudados retrospectivamente em um hospital de referência no Sul do Brasil. Foram avaliados três diferentes períodos selecionados de forma randômica: 1997-1998, 2002-2003 e 2014-2015. Os organismos infecciosos mais frequentes e a sensibilidade in vitro a antibióticos foram registados. RESULTADOS: No primeiro período (1997-1998) houve 33 casos; os mais comuns foram: E. coli em 13 (36,1%), Staphylococcus coagulase-negativo em 6 (16,7%), K. pneumoniae em 5 (13,9%), S. aureus em 4 (11,1%) e S. faecalis em 3 (8,3%). No segundo período (2002-2003), houve 43 casos, os mais frequentes foram: Staphylococus coagulase-negativo em 16 (35,5%), S. aureus em 8 (17,8%), E. coli em 7 (15,5%) e K. pneumoniae em 3 (6,7%). No terceiro período (2014-2015), houve 58 casos (sete com duas bactérias), os mais frequentes foram: E. coli em 15 (23,1%), S. viridans em 12 (18,5%), K. pneumoniae em 10 (15,4%) e E. faecium 5 (7,7%). Nenhum paciente estava usando profilaxia antibiótica. Quando considerados todos os estafilococos, a prevalência aumentou para taxas da ordem de 50% no segundo período, apresentando redução no terceiro período avaliado. Do mesmo modo, a prevalência de E coli resistente aumentou, chegando a 14%. CONCLUSÃO: Houve modificação da população bacteriana causadora de peritonite bacteriana espontânea, com alta frequência de organismos gram-positivos, bem como aumento da resistência aos antibióticos tradicionalmente recomendados. Este estudo sugere uma provável inclusão iminente de um medicamento contra organismos gram-positivos no tratamento empírico da peritonite bacteriana espontânea.

RESUMO

INTRODUCTION: Many patients coinfected with the human immunodeficiency virus (HIV) and hepatitis C virus (HCV) are using highly active antiretroviral therapy (HAART) and HCV therapy with peginterferon (PEG-IFN) and ribavirina (RBV) because the use of direct-acting antivirals is not a reality in some countries. To know the impact of such medications in the sustained virological response (SVR) during HCV treatment is of great importance. METHODOLOGY: This was a retrospective cohort study of 215 coinfected HIV/HCV patients. The patients were treated with PEG-IFN and RBV between 2007 and 2013 and analyzed by intention to treat. Treatment-experienced patients to HCV and carriers of hepatitis B were excluded. Demographic data (gender, age), mode of infection, HCV genotype, HCV viral load, hepatic fibrosis, HIV status, and type of PEG were evaluated. One hundred eighty-eight (87.4%) patients were using HAART. RESULTS: SVR was achieved in 55 (29.3%) patients using HAART and in 9 (33.3%) patients not using HAART (p = 0.86). There was no difference in SVR between different HAART medications and regimens using two reverse transcriptase inhibitor nucleosides (NRTIs) or the use of protease inhibitors and non-NRTIs (27.1% versus 31.5%; p = 0.61). The predictive factors for obtaining SVR were low HCV viral load, non-1 genotype, and the use of peginterferon-α2a. CONCLUSIONS: The use of HAART does not influence the SVR of HCV under PEG-IFN and RBV therapy in HIV/HCV coinfected patients.

RESUMO

UNLABELLED: Although the protease inhibitors have revolutionized the therapy of chronic hepatitis C (CHC), the concomitant use of pegylated-interferon (PEG-IFN) and ribavirin (RBV) is associated to a high rate of adverse effects. In this study, we evaluated the consequences of PEG-IFN and RBV and their relationship with mortality in patients with cirrhosis. METHODS: Medical records of CHC who underwent treatment with PEG-IFN and RBV in a public hospital in Brazil were evaluated. All the patients with cirrhosis were selected, and their clinical and laboratory characteristics, response to treatment, side effects and mortality were evaluated. RESULTS: From the 1,059 patients with CHC, 257 cirrhotic patients were evaluated. Of these, 45 (17.5%) achieved sustained viral response (SVR). Early discontinuation of therapy occurred in 105 (40.8%) patients, of which 39 (15.2%) were due to serious adverse effects. The mortality rate among the 257 cirrhotic patients was 4.3%, occurring in 06/242 (2.4%) of the Child-A, and in 05/15 (33.3%) of the Child-B patients. In conclusion, the treatment of patients with cirrhosis due to HCV with PEG-IFN and RBV shows a low SVR rate and a high mortality, especially in patients with liver dysfunction.

RESUMO

Elucidation of the natural history of chronic hepatitis C (CHC) and the identification of risk factors for its progression to advanced liver disease have allowed many physicians to recommend deferral treatment (triple therapy) in favour of waiting for new drug availability for patients who are at low risk of progression to significant liver disease. Newer generation drugs are currently under development, and are expected to feature improved efficacy and safety profiles, as well as less complex and shorter duration delivery regimens, compared to the current standards of care. In addition, patients with cirrhosis and prior null responders have a low rate (around 15%) of achieving sustained virological response (SVR) with triple therapy, and physicians must also consider the decision to wait for new treatments in the future for these patients as well. Naïve patients are the most likely to achieve a close to 100% SVR rate; therefore, it may be advisable to recommend that patients with mild to moderate CHC should wait for the newer therapy options. In contrast, patients with advanced fibrosis and cirrhosis will be those with the greatest need for expedited therapeutic intervention. There remains a need, however, for establishing definitive clinical management guidelines to maximize the benefit of waiting for new drugs and minimize risk of side effects and non-response to the current triple therapy.

RESUMO

INTRODUCTION: Liver biopsy is a complementary method for diagnosis, staging and therapeutic guidance in liver diseases, where chronic viral hepatitis are the most acknowledged causes for the indication of histopathological study. The objective is to assess the patients' profile as well as the indication and results of percutaneous liver biopsies in a tertiary hospital. MATERIAL AND METHODS: A descriptive, cross-section study was carried out through the review of medical charts (retrospective cohort) of patients submitted to blind percutaneous liver biopsies (PLB) at a hospital in Porto Alegre, South Brazil, from October 1993 to December 2011. RESULTS: 1,955 PLB were carried out, the mean patients' age was 44.8 years old, and 1,127 (57.65%) were men. Chronic hepatitis C was the main indication (60.5%), followed by HCV-HIV coinfection (12.2%) and chronic hepatitis B (3.5%). Seven cases (0.3%) had complications, without deaths. CONCLUSION: PLB is a safe method and continues to be an important option to assist patients with chronic liver disease.

RESUMO

CONTEXT: The progression of liver fibrosis in patients coinfected by hepatitis C virus and human immunodeficiency virus (HCV/HIV) has been increasingly studied in the past decade. Studies made before the highly active antiretroviral therapy suggest that HIV can change the natural history of the HCV infection, leading to a faster progression of the liver fibrosis. OBJECTIVE: To evaluate and compare the fibrosis progression in two groups of patients (HCV/HIV coinfected and HCV monoinfected) METHODS: Seventy patients HCV monoinfected and 26 patients HCV/HIV coinfected who had not undertaken HCV treatment and were submitted to serial percutaneous liver biopsies were retrospectively evaluated. There was no difference in the fibrosis progression between the two groups. CONCLUSION: The fibrosis grade evolution was not worse in the coinfected patients. The immunosuppression absence and the shortest time period between the biopsies in the coinfected group are possible explanations.

Contexto A progressão da fibrose hepática em pacientes coinfectados pelos vírus da hepatite C (VHC) e da imunodeficiência humana (VHC/HIV) tem sido mais estudada na última década. Estudos realizados antes da terapia antiretroviral de alta potência (HAART) sugerem que o HIV pode mudar a história natural da infecção pelo VHC, levando a uma progressão mais rápida da fibrose hepática. Objetivo Avaliar e comparar a progressão de fibrose em duas populações de pacientes (coinfectados VHC/HIV e monoinfectados VHC). Métodos Foram avaliados retrospectivamente 70 pacientes monoinfectados VHC e 26 coinfectados VHC/HIV nunca tratados para o VHC e que haviam realizado duas biopsias hepáticas seriadas. Não houve diferença na progressão de fibrose entre os dois grupos. Conclusão A evolução do grau de fibrose não foi pior nos pacientes coinfectados. A ausência de imunodepressão e o menor intervalo de tempo entre as biopsias no grupo de coinfectados são possíveis justificativas. .

RESUMO

The incidence of acute hepatitis C has decreased in the world. However, new cases are still reported. The objective of this study was to obtain data of acute hepatitis C in Brazil and to identify risk factors of transmission, diagnostic criteria, clinical presentation, evolution, and treatment. A questionnaire was sent to all members of the Brazilian Society of Hepatology. Sixteen centers participated with a total of 170 cases between 2000 and 2008. Among them, 37 had chronic renal failure on hemodialysis and were evaluated separately. The main diagnostic criterion in non-uremic patients was ALT (alanine aminotransferase) elevation associated with risk factors. In patients with chronic renal failure, anti-hepatitis C virus (HCV) seroconversion was the most frequent criterion. Among the 133 non-uremic patients the main risk factors were hospital procedures, whereas in hemodialysis patients, dialysis was the single risk factor in 95% of the cases. Jaundice was more frequent in non-uremic patients (82% vs. 13%; P < 0.001) and ALT levels were higher in these individuals (P < 0.001). Spontaneous clearance was more frequent in non-uremic patients (51% vs. 3%; P < 0.001). Sixty-five patients were treated: 39 non-uremic patients and 26 on dialysis. Sustained virological response rates were 60% for non-uremic and 58% for uremic patients (P = 0.98). There was no association of these rates with the study variables. These findings show that cases of acute hepatitis C are still occurring and have been related predominantly to hospital procedures. Measures to prevent nosocomial transmission should be adopted rigorously and followed to minimize this important source of infection observed in this survey.

RESUMO

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.

RESUMO

CONTEXT: It has been suggested that coinfected patients HCV/HIV must be treated with pegylated interferon associated to ribavirin (PEG+RBV), because of better taxes of sustained virological response when compared to those treated with conventional interferon associated to ribavirin (IFN+RBV). There are few studies in the literature comparing these two treatments options in this population. OBJECTIVE: To evaluate the sustained virological response to the treatment with IFN+RBV versus PEG+RBV in coinfected patients HCV/HIV genotype 1, in a public health program. METHODS: It is a cohort study, where the data of the coinfected patients treated with IFN+RBV (before 2002) or PEG+RBV (from 2002) during 48 weeks in the Brazilian Health Ministry program were reviewed. Demographic characteristics were evaluated (age, gender and weight), CD4 cell count and histopathology - inflammatory activity (A) and fibrosis grade, by METAVIR classification. The significance level adopted was 5%. RESULTS: Eighty one patients were evaluated, 22 treated with IFN+RBV and 59 treated with PEG+RBV. Both were similar relating to age, gender, weight, CD4 cell count and fibrosis grade. Those treated with IFN+RBV presented a greater proportion of A2+A3 patients than those treated with PEG+RBV (P<0.01). The sustained virological response was 14% versus 23% in those using IFN+RBV or PEG+RBV respectively (P = 0.54). The Odds Ratio was 1.9 (0.5 to 7.3). CONCLUSION: Coinfected patients HCV/HIV genotype 1 treated with PEG+RBV presented 1.9 more chance to obtain sustained virological response than those treated with IFN+RBV, however without statistical significance.

RESUMO

Ictiose adquirida é um distúrbio raro da queratinização, associado a diversas doenças, como neoplasias. Aqui relatamos o caso de uma paciente que se apresentou com ictiose de início recente e no decorrer da investigação foi descoberta hepatite B crônica e linfoma de Hodgkin. Não encontramos relatos da associação destas três entidades na literatura.

RESUMO

CONTEXTO: Tem sido sugerido que os pacientes coinfectados por vírus da hepatite C e da imunodeficiência humana (VHC/HIV) devam ser tratados com interferon peguilado associado à ribavirina (PEG+RBV) porque as taxas de resposta virológica sustentada seriam maiores do que aquelas obtidas com interferon convencional associado à ribavirina (IFN+RBV). No entanto, há escassez de trabalhos na literatura comparando as duas opções de tratamento nesta população de pacientes, em especial fora do cenário de ensaios clínicos. OBJETIVO: Avaliar a resposta virológica sustentada ao tratamento com IFN+RBV versus PEG+RBV em pacientes coinfectados pelo vírus da hepatite C genótipo 1 e vírus da imunodeficiência humana (VHC-1/HIV), no âmbito do programa do Ministério da Saúde. MÉTODOS: Trata-se de estudo de coorte misto, onde foram revisados prontuários de pacientes coinfectados por VHC-1/HIV tratados com IFN+RBV (antes de 2002) ou PEG+RBV (a partir de 2002) pelo período de 48 semanas, no âmbito da Secretaria da Saúde do Estado do Rio Grande do Sul. Foram avaliadas as características demográficas (idade, gênero e peso), contagem de células CD4 e histopatologia - atividade inflamatória (A) e fibrose - segundo classificação METAVIR. O nível de significância adotado na análise estatística foi de 5 por cento. RESULTADOS: Foram avaliados 81 pacientes coinfectados por VHC-1/HIV, 22 que utilizaram IFN+RBV e 59 que utilizaram PEG+RBV por 48 semanas. Os grupos eram semelhantes no que tange à média de idade, gênero, peso, contagem de células CD4 e grau de fibrose. Os pacientes que utilizaram IFN+RBV apresentaram maior atividade histológica com proporção de A2+A3 que superava aqueles que utilizaram PEG+RBV (P<0,01). A resposta virológica sustentada foi 14 por cento no grupo que utilizou IFN+RBV e 23 por cento naqueles que utilizaram PEG+RBV (P = 0,54), com Odds Ratio de 1,9 (0,5 a 7,3). CONCLUSÃO: Os pacientes coinfectados por HCV-1/HIV tratados com PEG+RBV apresentaram...

RESUMO

Objetivos: Avaliar a relação entre parâmetros laboratoriais e o grau de fibrose e atividade inflamatória na biópsia hepática. Metodologia: Estudo transversal de análise de dados laboratoriais e histopatológicos obtidos de forma consecutiva em 210 pacientes com infecção por VHC que foram submetidos à biópsia hepática às cegas. Foram avaliados alanina e aspartato-aminotransferase (ALT e AST), plaquetas, albumina, tempo de protrombina (TP) e o índice APRI (AST/plaquetas). O exame histopatológico foi classificado segundo o escore METAVIR. Para análise estatística, foi adotado um nível de significância de 5%. Resultados: A população foi constituída por 109 (51,9%) homens e 101 mulheres. A média de idade foi de 48,47 ± 1,31 anos. Quanto ao TP, albumina e AST isoladamente, não houve correlação com atividade ou fibrose. Houve correlação negativa entre plaquetas e o grau de fibrose. Utilizando os dados combinados através de índices APRI e ALT/plaquetas, as correlações são mais consistentes e significativas. Ambos os índices apresentaram boa correlação com o grau de fibrose. Conclusões: Dentre os parâmetros bioquímicos avaliados no presente estudo, o índice APRI e a relação ALT/plaquetas apresentaram melhor correlação com o grau de fibrose. Entretanto, não houve marcador que mostrasse uma relação sensibilidade/especificidade adequada para não justificar a realização de biópsia hepática (AU)


Objective: To correlate biochemical parameters with liver biopsy findings regarding fibrosis grade and inflammatory activity. Methods: A cross sectional study was designed to access the association of liver tests and histopathological data of 210 patients with hepatitis C virus. Platelets count, alanine and aspartate-aminotransferases (ALT and AST), albumin, the protrombin time (PT) and the APRI score (AST/platelets) were correlated with histopathological findings classified by METAVIR score. A significance level of 5% was used to test the association between variables. Results: There were 109 (51.9%) men and 101 women. The mean age was 48.47 +/- 1.31 years. PT, albumin and AST showed no correlation with inflammatory activity or fibrosis grade. There was a negative correlation between platelets and the fibrosis grade. This correlation was consistent with APRI score and ALT/platelets index. Both scores presented a good correlation with the fibrosis grade. Conclusions: APRI and ALT/platelets score presented significant correlation with the fibrosis grade. However, none of those tests showed sensitivity and specificity enough to replace liver biopsy (AU)

RESUMO

BACKGROUND: Spontaneous bacterial peritonitis is a serious complication in cirrhotic patients, and the changes in the microbiological characteristics reported in the last years are impacting the choice of antibiotic used in the treatment. AIM: To evaluate the change in the epidemiology and antibiotic resistance of the bacteria causing spontaneous bacterial peritonitis in a 7 years period. METHODS: All the cases of cirrhotic patients with spontaneous bacterial peritonitis with positive cultural examination were retrospectively studied. Two periods were evaluated: 1997-1998 and 2002-2003. The most frequent infecting organisms and the sensitivity in vitro to antibiotics were registered. RESULTS: In the first period (1997-1998) there were 33 cases, 3 (9%) with polymicrobial infection. The most common were: E.coli in 13 (36,11%), Staphylococcus coagulase-negative in 6 (16,66%), K. pneumoniae in 5 (13,88%), S. aureus in 4 (11,11%) and S. faecalis in 3 (8,33%). In 2003-2004, there were 43 cases, 2 (5%) with polymicrobial infection. The most frequent were: Staphylococus coagulase-negative in 16 (35,55%), S. aureus in 8 (17,77%), E. coli in 7 (15,55%) and K. pneumoniae in 3 (6,66%). No one was using antibiotic prophilaxys. The prevalence of S. aureus methicillin-resitant to quinolone and trimethoprim-sulfamethoxazole changed from 25% to 50%, and vancomicin was the only one with absolute activity during all the period. In the same way, the prevalence of E. coli resistant to third generation cephalosporin and to quinolone changed from 0% to 16%. CONCLUSION: There was a modification of the bacterial population causing spontaneous bacterial peritonitis, with high frequency of gram-positive organisms, as well as an increase in the resistance to the traditionally recommended antibiotics. This study suggests a probable imminent inclusion of a drug against gram-positive organisms in the empiric treatment of spontaneous bacterial peritonitis.
