SUMMARY. The burden of disease due to chronic viral hepatitis constitutes a global threat. In many Balkan and Mediterranean countries, the disease burden due to viral hepatitis remains largely unrecognized, including in highrisk groups and migrants, because of a lack of reliable epidemiological data, suggesting the need for better and targeted surveillance for public health gains. In many countries, the burden of chronic liver disease due to hepatitis B and C is increasing due to ageing of unvaccinated populations and migration, and a probable increase in drug injecting. Targeted vaccination strategies for hepatitis B virus (HBV) among risk groups and harm reduction interventions at adequate scale and coverage for injecting drug users are needed. Transmission of HBV and hepatitis C virus (HCV) in healthcare settings and a higher prevalence of HBV and HCV among recipients of blood and blood products in the Balkan and North African countries highlight the need to implement and monitor universal precautions in these settings and use voluntary, nonremunerated, repeat donors. Progress in drug discovery has improved outcomes of treatment for both HBV and HCV, although access is limited by the high costs of these drugs and resources available for health care. Egypt, with the highest burden of hepatitis C in the world, provides treatment through its National Control Strategy. Addressing the burden of viral hepatitis in the Balkan and Mediterranean regions will require national commitments in the form of strategic plans, financial and human resources, normative guidance and technical support from regional agencies and research.

SUMMARY. The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 15 countries in Europe, the Middle East and Asia, and the relative impact of two scenarios was considered: [1] increased treatment efficacy while holding the annual number of treated patients constant and [2] increased treatment efficacy and an increased annual number of treated patients. Increasing levels of diagnosis and treatment, in combination with improved treatment efficacy, were critical for achieving substantial reductions in disease burden. A 90% reduction in total HCV infections within 15 years is feasible in most countries studied, but it required a coordinated effort to introduce harm reduction programmes to reduce new infections, screening to identify those already infected and treatment with high cure rate therapies. This suggests that increased capacity for screening and treatment will be critical in many countries. Birth cohort screening is a helpful tool for maximizing resources. Among European countries, the majority of patients were born between 1940 and 1985. A wider range of birth cohorts was seen in the Middle East and Asia (between 1925 and 1995).

Thirty-two patients had surgery for hepatic echinococcal cysts (HEC). Serious complications were observed in 16 patients (50%): cyst recurrence (n = 4), infected residual cyst cavity (n = 7), infected residual cyst cavity with biliary and duodenal fistulae (n = 2), recurrent biliary obstruction following open surgery for a ruptured HEC into the biliary tree (n = 2), delayed rupture of an HEC into the biliary tree following laparoscopic surgery with secondary biliary obstruction (n = 1). These major complications were successfully managed by percutaneous methods in 8 of 16 patients while antihelmintic therapy was sufficient in two patients with a small recurrent cyst and ERCP was used in one patient to relieve biliary obstruction. Surgery was required in two patients only. With a success rate of 87.5%, the nonsurgical approach is the preferred method for treating a post-surgical complication.
