Trends in hepatitis C-related mortality in Switzerland.

In order to accurately assess the burden of hepatitis C (HCV) and develop effective interventions, we must understand the magnitude and trends of mortality related to the disease. In the United States, HCV-related mortality is continuously increasing. We have no comparable data for Switzerland and other European countries, although a modelling study predicted a similar increase. We analysed time trends (1 January 1995-31 December 2014) in HCV-specific mortality rates in the Swiss general population using the death registry of the Swiss Federal Statistical Office (SFSO). We compared HCV-related mortality to HIV-related and hepatitis B (HBV)-related mortality. To determine potential under-reporting in HCV-related mortality, we probabilistically linked the SFSO data to persons who died in the Swiss Hepatitis C Cohort Study (SCCS). SFSO data showed that HCV-related mortality more than doubled between 1995 and 2003, but has since stabilized at ~2.5/100 000 person-years. Since 2000, HCV-related mortality has been higher than HIV-related mortality and was about fivefold higher in 2014. HBV-related mortality remained low at ~0.5/100 000 person-years. Of 4556 persons in the SCCS, 421 have died and 86.2% could be linked to the death registry. According to the SCCS, 133 deaths were HCV-related. HCV was not mentioned on the SFSO death certificate of 45% of these (n = 60/133). In conclusion, HCV-related mortality remained constant, possibly because quality of care was high, or because of under-reporting or because mortality has not yet increased. However, HCV-related mortality is now much higher than HIV- and HBV-related mortality, and under-reporting was common.

Critical review of the use of erythropoietin in the treatment of anaemia during therapy for chronic hepatitis C.

Combined pegylated interferon (PegIFN) and ribavirin represents the standard therapy for patients with chronic hepatitis C (CHC), which allows for sustained viral response (SVR) in up to 90% of patients depending on certain viral and host factors. Clinical studies have demonstrated the importance of adherence to therapy, that is, the ability of patients to tolerate and sustain a fully dosed therapy regimen. Adherence is markedly impaired by treatment-related adverse effects. In particular, haemolytic anaemia often requires dose reduction or termination of ribavirin treatment, which compromises treatment efficacy. Recent evidence points to a beneficial role of recombinant erythropoietin (EPO) in alleviating ribavirin-induced anaemia thereby improving quality of life, enabling higher ribavirin dosage and consequently improving SVR. However, no general consensus exists regarding the use of EPO for specific indications: its optimal dosing, treatment benefits and potential risks or cost efficiency. The Swiss Association for the Study of the Liver (SASL) has therefore organized an expert meeting to critically review and discuss the current evidence and to phrase recommendations for clinical practice. A consensus was reached recommending the use of EPO for patients infected with viral genotype 1 developing significant anaemia below 100 g/L haemoglobin and a haematocrit of <30% during standard therapy to improve quality of life and sustain optimal ribavirin dose. However, the evidence supporting its use in patients with pre-existing anaemia, non-1 viral genotypes, a former relapse or nonresponse, liver transplant recipients and cardiovascular or pulmonary disease is considered insufficient.

Expert clinical management of autoimmune hepatitis in the real world.

BACKGROUND: High-quality data on the management of autoimmune hepatitis (AIH) are scarce. Despite published guidelines, management of AIH is still expert based rather than evidence based. AIM: To survey expert hepatologists, asking each to describe their practices in the management of patients with AIH. METHODS: A survey questionnaire was distributed to members of the International AIH Group. The questionnaire consisted of four clinical scenarios on different presentations of AIH. RESULTS: Sixty surveys were sent, out of which 37 were returned. None reported budesonide as a first line induction agent for the acute presentation of AIH. Five (14%) participants reported using thiopurine S-methyltransferase measurements before commencement of thiopurine maintenance therapy. Thirteen (35%) routinely perform liver biopsy at 2 years of biochemical remission. If histological inflammatory activity is absent, four (11%) participants reduced azathioprine, whereas 10 (27%) attempted withdrawal altogether. Regarding the management of difficult-to-treat patients, mycophenolate mofetil is the most widely used second-line agent (n = ~450 in 28 centres), whereas tacrolimus (n = ~115 in 21 centres) and ciclosporin (n = ~112 in 18 centres) are less often reported. One centre reported considerable experience with infliximab, while rescue therapy with rituximab has been tried in seven centres. CONCLUSIONS: There is a wide variation in the management of patients with autoimmune hepatitis even among the most expert in the field. Although good quality evidence is lacking, there is considerable experience with second-line therapies. Future prospective studies should address these issues, so that we move from an expert- to an evidence- and personalised-based care in autoimmune hepatitis.
