RESUMO
BACKGROUND & AIMS: Adherence to antiviral treatment is important to achieve sustained virological response (SVR) in chronic hepatitis C (CHC). We evaluated the efficiency of a multidisciplinary support programme (MSP), based on published HIV treatment experience, to increase patient adherence and the efficacy of pegylated interferon alfa-2a and ribavirin in CHC. METHODS: 447 patients receiving antiviral treatment were distributed into 3 groups: control group (2003-2004, n=147), MSP group (2005-2006, n=131), and MSP-validation group (2007-2009, n=169). The MSP group included two hepatologists, two nurses, one pharmacist, one psychologist, one administrative assistant, and one psychiatrist. Cost-effectiveness analysis was performed using a Markov model. RESULTS: Adherence and SVR rates were higher in the MSP (94.6% and 77.1%) and MSP-validation (91.7% and 74.6%) groups compared to controls (78.9% and 61.9%) (p<0.05 in all cases). SVR was higher in genotypes 1 or 4 followed by the MSP group vs. controls (67.7% vs. 48.9%, p=0.02) compared with genotypes 2 or 3 (87.7% vs. 81.4%, p=n.s.). The MSP was the main predictive factor of SVR in patients with genotype 1. The rate of adherence in patients with psychiatric disorders was higher in the MSP groups (n=95, 90.5%) compared to controls (n=28, 75.7%) (p=0.02). The cost per patient was 13,319 in the MSP group and 16,184 in the control group. The MSP group achieved more quality-adjusted life years (QALYs) (16.317 QALYs) than controls (15.814 QALYs) and was dominant in all genotypes. CONCLUSIONS: MSP improves patient compliance and increases the efficiency of antiviral treatment in CHC, being cost-effective.

BACKGROUND/AIMS: Since few data are available concerning the clinical course of decompensated hepatitis C virus (HCV)-related cirrhosis, the aim of the present study was to define the natural long-term course after the first hepatic decompensation. METHODS: Cohort of 200 consecutive patients with HCV-related cirrhosis, and without known hepatocellular carcinoma (HCC), hospitalized for the first hepatic decompensation. RESULTS: Ascites was the most frequent first decompensation (48%), followed by portal hypertensive gastrointestinal bleeding (PHGB) (32.5%), severe bacterial infection (BI) (14.5%) and hepatic encephalopathy (HE) (5%). During follow-up (34+/-2 months) there were 519 readmissions, HCC developed in 33 (16.5%) patients, and death occurred in 85 patients (42.5%). The probability of survival after diagnosis of decompensated cirrhosis was 81.8 and 50.8% at 1 and 5 years, respectively. HE and/or ascites as the first hepatic decompensation, baseline Child-Pugh score, age, and presence of more than one decompensation during follow-up were independently correlated with survival. CONCLUSIONS: Once decompensated HCV-related cirrhosis was established, patients showed not only a very high frequency of readmissions, but also developed decompensations different from the initial one. These results contribute to defining the natural course and prognosis of decompensated HCV-related cirrhosis.
