    Abstract: CONTEXT: Portal hypertension plays an important role in the pathogenesis of ascites. OBJECTIVES: To evaluate the hepatic venous pressure gradient and the presence of ascites in cirrhotic patients. METHODS: Eighty-three patients with cirrhosis were evaluated. All of the patients were submitted to ultrasonography to identify ascites and to a hepatic hemodynamic investigation to determine the hepatic venous pressure gradient. RESULTS: In the population evaluated, ascites was observed in 70 patients (84.3%), and the mean hepatic venous pressure gradient was 15.26 ± 6.46 mm Hg. There was no statistically significant difference (P = 0.061) between the means of hepatic venous pressure gradient in patients with (14.70 ± 6.43 mm Hg) and without ascites (18.64 ± 5.78 mm Hg). When using a cut-off point of 8 mm Hg in order to assess the risk of developing ascites, patients with hepatic venous pressure gradient above 8 mm Hg were found to have a relative risk of 0.876 (CI = 0.74-1.03), (P = 0.446) of progressing to ascites. CONCLUSIONS: The pressure level of 8 mm Hg, as determined by the hepatic venous pressure gradient, does not define the presence or absence of ascites in the cirrhotic patient, and in view of the similarity between mean pressures in patients with or without peritoneal effusion, it is impossible to define a cut-off point for the emergence of such complication.

    Abstract: BACKGROUND: Hepatitis B and C viruses and human immunodeficiency virus share the same route of transmission, and the prevalence of HBV and HCV infection in patients infected with HIV is greater than it is in the general population. AIM: To determine the prevalence of hepatitis B and C markers in a population of patients with HIV as well as the risk factors involved. PATIENTS AND METHODS: From 5,870 registration forms of patients with HIV of an Infectology Unit, 587 were randomly selected. From these, the 343 which had investigated the presence of any hepatitis B (HBsAg, anti-HBc or anti-HBs) or C (anti-HCV) marker were retrospectively analyzed. RESULTS: HBsAg was positive in 14/306 (4.6%), anti-HBs was positive in 40/154(26.0%), and anti-HBc in 79/205 (38.5%). The anti-HCV test was reactive in 126/330 (38.2%). HBV and HCV co-infection was observed in 7 of the 296 patients who had both HBsAg and anti-HCV tests (2.4%). For those who were HBsAg positive, the main exposure factor was homosexual intercourse (50.0%). For those who were anti-HCV reactive, the main risk factor was intravenous drug use (75.3%). In the HIV mono-infected (185 patients), the most prevalent exposure risk factor was promiscuous heterosexual practices or sexual intercourse with a spouse infected with HIV (83 patients - 44.9%). CONCLUSION: In our environment HBV-HIV and HCV-HIV co-infections are frequent, a greater relevance being observed in the association between HCV and HIV.

    Abstract: CONTEXTO: Tanto a hepatite crônica pelo vírus C quanto a doença hepática gordurosa não-alcoólica são reconhecidas como causas frequentes de doença hepática nos países ocidentais. É comum observar a concomitância das duas doenças e a influência da esteatose na resposta virológica sustentada dos pacientes com hepatite crônica pelo vírus C. OBJETIVO: Avaliar a resposta virológica sustentada nos pacientes com hepatite crônica pelo vírus C de acordo com a presença de esteatose. MÉTODOS: Foram avaliados, retrospectivamente, 160 pacientes com hepatite crônica C. Dados demográficos, como sexo, idade, índice de massa corpórea, presença de diabetes mellitus e hipertensão arterial sistêmica, genótipo do vírus e uso de interferon peguilado foram analisados, bem como o estadiamento e a presença de esteatose, quando da histologia. RESULTADOS: A maioria dos pacientes era masculina (57,5%), com média de idade de 48 anos ± 9,7. O genótipo mais frequente foi o 3 (56,9%) e, na avaliação histológica, foi observada esteatose em 65% dos pacientes (104/160). A resposta virológica sustentada nos pacientes com esteatose foi de 38,5%, sendo de 32,1% nos pacientes sem esteatose (P = 0,54). Quando se analisaram possíveis fatores associados à presença de esteatose, somente índice de massa corpórea e hipertensão arterial sistêmica estiveram associados de forma significativa. Quando se avaliaram em regressão logística os fatores que influenciaram a resposta virológica sustentada, genótipo e uso de interferon peguilado mostraram-se fatores independentes associados à resposta. CONCLUSÃO: A presença de esteatose hepática não influenciou a resposta virológica sustentada de pacientes com hepatite crônica pelo vírus C tratados com interferon e ribavirina.

    Abstract: RESUMO CONTEXTO: A doença hepática gordurosa não-alcoólica (DHGNA) é a doença hepática mais prevalente no mundo. Nos Estados Unidos, a DHGNA já é a segunda causa de transplante hepático. O espectro da doença abrange desde a esteatose simples, que apresenta curso benigno, até esteato-hepatite não-alcoólica (EHNA), que pode progredir para cirrose e suas complicações. O desenvolvimento de métodos não invasivos para o diagnóstico e estadiamento da EHNA e da fibrose hepática visa diminuir a necessidade de biópsia hepática, um procedimento invasivo e não raro associado a complicações. OBJETIVO: Analisar o desempenho do índice triglicerídeo-glicose (TyG Index) para o diagnóstico e estadiamento da DHGNA em pacientes obesos. MÉTODOS: Este é um estudo transversal retrospectivo. Foram analisados todos os prontuários de pacientes candidatos a cirurgia bariátrica em um hospital de referência do Sul do Brasil e calculado o TyG Index, um escore composto por dois exames laboratoriais (triglicerídeos e glicose de jejum), realizados previamente à cirurgia. O desempenho do TyG Index em relação aos achados anatomopatológicos hepáticos foi avaliado, e calculada a curva ROC para avaliação de esteatose simples, EHNA e fibrose hepática. O NAFLD Fibrosis Score (NFS) também foi avaliado. RESULTADOS: Foram avaliados 423 pacientes. O melhor ponto de corte do TyG Index para a exclusão de esteatose simples significativa (grau 2-3) foi de 8,76, com sensibilidade 67,6%, especificidade 65,1%, valor preditivo positivo (VPP) 46,3%, valor preditivo negativo (VPN) 81,8%, acurácia 65,8% e AUROC 0,66 (P=0,005). Na avaliação de EHNA significativa (grau 2-3), o melhor ponto de corte foi de 8,82 com sensibilidade 57,3%, especificidade 58,6%, VPP 33,7%, VPN 78,8%, acurácia 58,8% e AUROC 0,58 (P=0,022). Em relação à fibrose avançada (grau 3-4), o melhor ponto de corte do TyG Index foi de 8,91 com sensibilidade 61,8%, especificidade 62,5%, VPP 13,8%, VPN 94,4%, acurácia 62,4% e AUROC 0,69 (P 〈 0,001). Ao analisarmos o desempenho do NFS no diagnóstico de fibrose avançada, o ponto de corte de 〈 -1,455 excluiu fibrose avançada com sensibilidade 59,4%, especificidade 51%, VPP 11%, VPN 92,4% e acurácia 51,7%. Entretanto, o ponto de corte de 0,676 para fibrose avançada apresentou sensibilidade de 21,9%, especificidade 83%, VPP 11,7%, VPN 91,2% e acurácia 77,3%. A AUROC foi de 0,54 (P=0,480). CONCLUSÃO: O TyG Index não apresentou bom desempenho para o diagnóstico e estadiamento da esteatose simples e da EHNA. Entretanto, foi capaz de excluir fibrose avançada em pacientes obesos candidatos a cirurgia bariátrica.

    Abstract: Contexto O transplante é a única cura para a cirrose descompensada. O Model for End-Stage Liver Disease (MELD) é usado na alocação de órgãos. Objetivos Comparar a sobrevida da população listada para transplante nas eras pré e pós-MELD e estimar sua sobrevida a longo prazo. Métodos Este é um estudo retrospectivo, de cirróticos listados para transplante nas eras pré e pós-MELD. Curvas de sobrevida foram criadas através do modelo de Kaplan-Meier. O modelo de Cox foi utilizada para determinar fatores de risco para mortalidade. Os modelos exponencial, Weibull, log-normal e Gompertz foram usados para estimar sobrevida de longo prazo. Resultados Incluíram-se 162 pacientes listados na era pré-MELD e 184 listados na pós-MELD. A curva de Kaplan-Meier para os pacientes listados na era pós-MELD foi melhor que a da pré-MELD (P = 0,009). Esta diferença permaneceu nas estimativas de longo prazo, com sobrevida de 53,54% em 5 anos e de 44,64% em 10 anos para pacientes listados na era pós-MELD e de 43,17% e 41,75% no período pré-MELD. A era em que os pacientes eram listados (P = 0,010) e o MELD de inscrição (P 〈 0,001) estiveram associados de maneira independente à sobrevida, com razão de riscos de 0,664 (intervalo de confiança-IC 95% = 0,487-0,906) e de 1,069 (IC 95% = 1,043-1,095). Conclusões A política de transplantes baseada no escore MELD é superior à baseada no tempo de espera em lista, promovendo melhor sobrevida, mesmo em longo prazo.

    Abstract: Bacterial infections are among the main causes of death in patients with cirrhosis. While there are unquestionable benefits of using albumin in patients with spontaneous bacterial peritonitis, the benefits of albumin are controversial for those with extraperitoneal infections. The aim was to compare the use of albumin associated to antibiotics and antibiotics alone in cirrhotic patients with extraperitoneal infections. Methods A systematic review was performed using MEDLINE and Embase databases. Randomized controlled trials comparing albumin associated to antibiotics and antibiotics alone in cirrhotic patients with extraperitoneal infections were considered eligible, as long as at least one of the following outcomes was evaluated: mortality and renal dysfunction. Meta‐analysis was performed using the random effects model, through the Mantel–Haenszel method. The study protocol was registered at PROSPERO platform (CRD42018107191). Results The literature search yielded 812 references. Three randomized controlled trials fulfilled the selection criteria and were included in this meta‐analysis. There was no evidence of significant difference between the groups regarding mortality in 30 days (risk ratio [RR] = 1.62, 95% confidence interval [CI] : 0.92–2.84, P = 0.09, I 2 = 0%) or in 90 days (RR = 1.27, 95% CI: 0.89–1.83, P = 0.19, I 2 = 0%). Regarding renal dysfunction, there was also no evidence of significant difference between the groups (RR = 0.55, 95% CI: 0.25–1.19, P = 0.13, I 2 = 0%). Conclusion There is no evidence of significant benefits of using albumin for cirrhotic patients with extraperitoneal infections regarding mortality or renal dysfunction.

    Abstract: BACKGROUD: Hepatic steatosis is a common finding in patients with hepatitis C, mainly virus C genotype 3. Steatosis in these cases might be associated with antiviral treatment response and with prognosis of chronic hepatitis. AIMS: To determine the presence of steatosis and non-alcoholic steatohepatitis in chronic hepatitis C and its correlation with genotype and hepatic fibrosis. PATIENTS AND METHODS: One hundred and twenty patients with chronic hepatitis C were retrospectively evaluated; genotype was done in 102 patients. All specimens were stained with hematoxylin-eosin, picrosirius and perls. Staging of hepatitis C was scored by Brazilian Classification and the diagnosis of non-alcoholic steatohepatitis by the American Association for the Study of Liver Diseases criteria RESULTS: Steatosis was found in 65 of 120 cases (54.2%); it was mild in 37/65 (56.9%), moderate in 12/65 (18.5%) and severe in 10/65 (15.4%). In relation to fibrosis, 80 of 120 patients had mild fibrosis F0-F2 (66.6%) and 40 (33.3%) had more advanced fibrosis (F3 or F4). Steatosis was associated with genotype 3 (76.7%) in comparison with other genotypes (49,0%). There were no relationship between steatosis and advanced fibrosis F3/F4 (52,5%) or mild fibrosis (54,4%). Non-alcoholic steatohepatitis was diagnosed in 8/120 cases (6.7%) and was significantly associated with hepatitis C virus genotype 3 and with advanced fibrosis (F3 and F4) CONCLUSIONS: The presence of steatosis and non-alcoholic steatohepatitis in chronic hepatitis C are associated to genotype 3; moreover non-alcoholic steatohepatitis was correlated with more advanced fibrosis.

    Abstract: BACKGROUND: The immune activation provoked by the hepatitis C virus can be deleterious in patients with human immunodeficiency virus, favouring the destruction of CD4 cells. By the other side, the immune restoration observed after the onset of antiretroviral therapy can be partially obscured in patients with the hepatitis C virus. AIM: The objective of the present study was to evaluate the impact of coinfection by hepatitis C virus and the human immunodeficiency virus in the cellular immunity. METHODS: Two groups of patients were considered: coinfected patients were prospectively evaluated in the gastroenterology clinic at "Hospital Nossa Senhora da Conceição", Porto Alegre, RS, Brazil (group 1 - 385 patients), and monoinfected patients by human immunodeficiency virus based on the review of the charts from the infectious diseases clinic (group 2 - 198 patients). Demographic (gender, race, age) CD4 and CD8 cell count, CD4/CD8 index and human immunodeficiency virus viral load were evaluated. A 5% significance level was adopted. RESULTS: There were no difference between the parameters evaluated: mean CD4 count (374,7 ± 215,7 x 357,5 ± 266,0), CD8 (1.512,4 ± 7.274,6 x 986,7 ± 436,4) and HIV viral load (83.744,2 ± 190.292,0 x 104.464,0 ± 486.880,5) respectively in both groups evaluated, as well as the proportion of patients with CD4/CD8 rate below 1. CONCLUSION: Coinfection by both viruses did not have a negative impact in relation to monoinfection by human immunodeficiency virus, and the immune profile was similar in all groups.
