Introduction. Moldova is the European country with the highest incidence of hepatocellular carcinoma (HCC) in both sexes. There is, however, no data comprehensively describing the presentation and the risk factors of HCC in the country. We decided to analyze cases of HCC recently received in a tertiary healthcare Institution from Chisinau, the Moldovian capital. Methods. A series of 148 primary liver tumors including 139 cases of HCC were retrospectively analyzed for demographic features, serological and biochemical data, and clinical presentation. Results. The mean age of patients was 59 ± 10 years (range: 19-66) with a M:F sex ratio of 1.9. Tumors appeared on full-blown liver cirrhosis in 83% of cases and were composed of multiple nodules at diagnosis in 36% of patients. Serum Alpha-fetoprotein was exceeding 10ng/mL in 76% of cases. Liver tumor and hepatitis were co-discovered in 34% of cases. More than 81% of hepatocellular carcinomas were associated with at least one hepatitis virus. Carriers of anti-hepatitis C virus were predominating (55% of cases) over patients seropositive for hepatitis B virus surface antigen (36%). Half of the latter were also infected with hepatitis Delta virus. In total, dual or triple infections were present in 24% and 7% of cases. Conclusions. The burden of infections with hepatitis viruses is particularly important in Moldova and corresponds to a situation commonly observed in countries of the Southern hemisphere. A pro-active policy of screening for persistent liver infection targeting population at risk of HCC (> 50 years) and coupled with the distribution of antivirals in positive cases should be rapidly implemented in Moldova to reduce incidence or primary liver cancer.

Ever since the first liver transplant in the Republic of Moldova in 2013 we have performed 30 liver transplantations, the first having been performed in collaboration with the surgical team from Romania, led by Professor Irinel Popescu. The serious deficit of available cadaveric organs has forced us to begin with right hemi-liver transplantation from a living donor. In one third of liver transplantations we used right hemi-liver graft from a living donor, and in 2/3 of cases whole liver graft was harvested from brain-dead donors. The indication for surgical intervention in most cases was hepatic cirrhosis of viral aetiology in terminal stages, three cases of hepatocellular carcinoma, and one case for each of primary biliary cirrhosis, drug-induced toxic hepatitis, and liver retransplantation caused by hepatic arterial thrombosis. 10 cadaveric grafts were harvested from elderly donors ( 65 years). In the early postoperative period, four recipients died (2 live donor graft recipients and 2 graft recipients from donors with brain death). Causes of death were: intracerebral haemorrhage in the early postoperative period - 1, acute graft rejection - 1, hepatic artery thrombosis - 1, primary graft dysfunction - 1. There were no deaths during the late postoperative period. Of the complications that occurred during the early postoperative period we can highlight acute graft rejection -2, hepatic arterial thrombosis - 1, intraabdominal postoperative haemorrhage - 1, hepatic artery thrombosis -1, biliary peritonitis - 1, primary graft dysfunction -1, seizures -1. Complications during the postoperative period: biliary peritonitis after choledochal drainage removal - 1, "small-for-size" - 2. The accumulated experience and the use of modern technologies has allowed us to reduce the postoperative mortality rate, as well as the rate of occurring complications, in order to transfer this surgical intervention from the category of exclusivity operations to the category of daily interventions.

This subject underlines the most important perioperative factors that predispose to early post-liver transplant respiratory complications. Despite advances in surgical techniques and anesthesiological management the lung may still suffer throughout the perioperative period from various types of injury, with different ensuing ventilatory impairments, and different clinical outcomes. The incidence, etiology, pathophysiological features, clinical manifestations, preventing measures, and outcomes of post-operative respiratory disorders in this setting are also reported.

SUMMARY. The aim of the work was to study the BEA score (Baseline Event-anticipation score) and its correlation with biological signs of liver laboratory syndromes in the patients with chronic hepatitis B and Delta.There were investigated prospectively 58 Caucasian patients with chronic hepatitis B and Delta (CHD), 28 women and 30 men, and 10 Caucasian patients with viral liver cirrhosis Delta (LCD). BEA score was estimated using the online calculator (http://hepatitis-delta.org/physicians-and-scientists/calculators/).There was estimated the BEA score and the indicators of the biological liver syndromes were studied. The correlation analysis was performed (after Spearman) between the score values of BEA parameters and the biological liver syndromes.It was established the direct correlation of the BEA score with the values of the levels of serum gamma-glutamyl transferees and with the serum total bilirubin in patients with HCD. In patients with LCD there was determined direct correlation of the BEA score with the total bilirubin and inverse correlation with the serum albumin values.We recommend modifying the BEA score by adding the albumin and GGT as predictors for developing complications related to liver disease.
