Questionnaire PLD-complaint-specific assessment identifies need for therapy in polycystic liver disease: A multi-centric prospective study.

BACKGROUND AND AIMS: Polycystic liver disease (PLD) can lead to extensive hepatomegaly. Symptom relief is the primary goal of the treatment. The role of the recently developed disease-specific questionnaires for identification of the thresholds and the assessment of therapy needs further investigation. METHODS: A five-year prospective multi-centric observational study in 21 hospitals in Belgium gathered a study population of 198 symptomatic PLD-patients of whom the disease-specific symptom questionnaire PLD-complaint-specific assessment (POLCA) scores were calculated. The thresholds of the POLCA score for the need for volume reduction therapy were analyzed. RESULTS: The study group consisted of mostly (82.8%) women with baseline mean age of 54.4 years ±11.2, median liver volume expressed as height-adjusted total liver volume(htLV) of 1994 mL (interquartile range [IQR] 1275; 3150) and median growth of the liver of +74 mL/year (IQR +3; +230). Volume reduction therapy was needed in 71 patients (35.9%). A POLCA severity score (SPI) ≥ 14 predicted the need for therapy both in the derivation (n = 63) and the validation cohort (n = 126). The thresholds to start somatostatin analogues (n = 55) or to consider liver transplantation (n = 18) were SPI scores of ≥14 and ≥ 18 and the corresponding mean htLVs were 2902 mL (IQR 1908; 3964) and 3607 mL (IQR 2901; 4337), respectively. Somatostatin analogues treatment resulted in a decrease in the SPI score -6.0 versus + 4.5 in patients without somatostatin analogues (p < 0.01). Changes in the SPI score were significantly different between the liver transplantation group and no liver transplantation group, +4.3 ± 7.1 versus -1.6 ± 4.9, respectively, (p < 0.01). CONCLUSION: A polycystic liver disease-specific questionnaire can be used as a guide on when to start a volume reduction therapy and to assess the effect of treatment.

Predicted effects of treatment for HCV infection vary among European countries.

BACKGROUND & AIMS: The dynamics of hepatitis C virus (HCV) infection, as well as screening practices and access to therapy, vary among European countries. It is important to determine the magnitude of the effects of such differences on incidence and mortality of infection. We compared the dynamics of infection and screening and treatment practices among Belgium, France, Germany, Italy, Spain, and the United Kingdom. We also assessed the effects of treatment with pegylated interferon and additional effects of triple therapy with protease inhibitors. METHODS: We created a country-specific Markov model of HCV progression based on published epidemiologic data (on HCV prevalence, screening, genotype, alcohol consumption among patients, and treatments) and reports of competitive and hepatocellular carcinoma mortality for the 6 countries. The model was used to predict the incidence of HCV-related cirrhosis and its mortality until 2021 for each country. RESULTS: From 2002 to 2011, antiviral therapy reduced the cumulative incidence of cirrhosis by 7.1% and deaths by 3.4% overall. Reductions in incidence and mortality values ranged from 4.0% and 1.9%, respectively, in Italy to 16.3% and 9.0%, respectively, in France. From 2012 to 2021, antiviral treatment of patients with HCV genotype 1 infection that includes protease inhibitor-based triple therapy will reduce the cumulative incidence of cirrhosis by 17.7% and mortality by 9.7% overall. The smallest reduction is predicted for Italy (incidence reduced by 10.1% and mortality by 5.4%) and the highest is for France (reductions of 34.3% and 20.7%, respectively). CONCLUSIONS: Although HCV infection is treated with the same therapies in different countries, the effects of the therapies on morbidity and mortality vary significantly. In addition to common guidelines that are based on virologic response-guided therapy, there is a need for public health policies based on population-guided therapy.

Resource use and cost of hepatitis C-related care.

BACKGROUND: Chronic hepatitis because of the hepatitis C virus (CHC) is a major health problem that can lead to decompensated cirrhosis, hepatocellular carcinoma, and eventually death, all of which are associated with significant healthcare costs. AIM: To update the cost of care of CHC according to the different severity stages of the disease in a west European country (Belgium). METHODS: Medical records of 157 patients, who were referred to the medical specialist at different stages of disease, were reviewed to identify the medical costs over a follow-up period of 3 years or 2 years in the case of liver transplantation (LT). Six disease stages were defined on the basis of histology (Metavir classification) and/or clinical data. RESULTS: In comparison with mild disease, the cost increased 1.6 times in the case of decompensated cirrhosis, 1.9 times in the case of hepatocellular carcinoma, and 3.4 in the case of LT. The costs for medication, hospitalization, and ambulatory care were, respectively, on the one hand, 81, 8, and 11% for mild disease and, on the other, 18, 79, and 3% for LT. In the case of a sustained viral response, the cost of follow-up within 3 years decreased by 45% for patients with mild and moderate disease. CONCLUSION: Antiviral treatment is the most important factor governing cost in mild and moderate disease, but once complications of CHC occur, hospitalization costs far exceed the cost of antiviral therapy. Already during the first 3 years of follow-up, sustained viral response decreased the cost significantly. Treatment of patients with CHC in an early stage has the potential to be cost-effective.
