    Abstract: Heterozygotes for Z or S alleles of alpha-1-antrypsin (AAT) have low serum AAT levels. Our aim was to compare the risk of hepatocellular carcinoma (HCC) in patients with liver cirrhosis carrying the SERPINA1 MM, MZ and MS genotypes. The study groups consisted of 1119 patients with liver cirrhosis of various aetiologies, and 3240 healthy individuals served as population controls. The MZ genotype was significantly more frequent in the study group (55/1119 vs. 87/3240, p 〈 0.0001). The MS genotype frequency was comparable in controls (32/119 vs. 101/3240, p = 0.84). MZ and MS heterozygotes had lower serum AAT level than MM homozygotes (medians: 0.90 g/L; 1.40 g/L and 1.67 g/L; p 〈 0.001 for both). There were significantly fewer patients with HCC in the cirrhosis group among MZ and MS heterozygotes than in MM homozygotes (5/55 and 1/32 respectively, vs. 243/1022, p 〈 0.01 for both). The risk of HCC was lower in MZ and MS heterozygotes than in MM homozygotes (OR 0.3202; 95% CI 0.1361–0.7719 and OR 0.1522; 95% CI 0.02941–0.7882, respectively). Multivariate analysis of HCC risk factors identified MZ or MS genotype carriage as a protective factor, whereas age, male sex, BMI and viral aetiology of cirrhosis increased HCC risk.

    Abstract: Introduction: Cytomegalovirus disease affecting the gastrointestinal tract is a rare but severe disease presenting particularly in people under immunosuppression, solid organ transplant recipients and AIDS patients with CD4 count under 100/mm3. When colon or small intestine are affected, the disease may be complicated by severe bleeding. CMV therapy includes antivirals and, in case of bleeding, methods of therapeutic endoscopy or interventional radiology. Case description: We present a case of a 74-year-old woman 3 years after kidney transplantation owing to vascular nephrosclerosis, treated with belatacept, mycophenolate mophetile and prednisone. She was admitted to hospital for acute dyspnoea. During hospitalisation, she presented with intestinal bleeding, but the endoscopic intervention at the first colonoscopy was not successful. She was referred to the Department of Hepatogastroenterology of the Institute of Clinical and Experimental Medicine and subsequent colonoscopy revealed a 15 cm long part of ileum with ulcerations as the source of bleeding. The histological assessment described a severe CMV enteritis. The CMV DNA blood level established by PCR was higher than 10 000 000 U/ml. The patient was treated with intravenous ganciclovir and she underwent selective embolization of the inferior mesenteric artery with an excellent clinical effect. Conclusions: CMV enteritis may be associated with a high mortality. The approach to therapy is multidisciplinary and needs collaboration of gastroenterologist, endoscopist and interventional radiologist. Key words: CMV – GIT bleeding – immunosuppression – transplantation
