AFP (alpha-fetoprotein) levels are increased during the development of HCC (hepatocellular carcinoma); nonetheless, it can also be produced by non-tumoral hepatocytes in conditions of high cell turnover. Our study aims to provide additional data regarding the causes of elevated AFP in patients with liver cirrhosis due to hepatitis C virus (HCV) infection. We conducted an observational prospective cohort study that included 2068 patients with compensated cirrhosis and chronic hepatitis C genotype 1b infection. The two main inclusion criteria were the presence of advanced liver fibrosis - Metavir stage F4 - diagnosed by FibroMax testing, Fibroscan or liver biopsy, and the presence of detectable HCV RNA in the serum. Plasmatic AFP levels were determined through the electrochemiluminescence method, with a standard value ranging from 0 to 7 ng/ml. All data were obtained from the Romanian National Health Agency. The average AFP serum levels in patients with compensated cirrhosis without HCC were 9.4 ng/ml (range 0.5 ÷ 406 ng/ml); 30.1% of patients had significantly increased levels of AFP (>15 ng/ml). High values of serum AFP in patients with compensated liver cirrhosis without HCC was correlated with more advanced age (p<0.001), severe necroinflammatory activity detected by FibroMax (p<0.001), severe NASH (p<0.001), severe steatosis (p<0.001), low platelets (p<0.001), increased values of AST and ALT (p<0.001).

Intestinal strictures are an important complication of Crohn's disease (CD), with ~40% of patients developing symptomatic obstruction within 10 years of diagnosis. However, there is a paucity of research examining the mechanisms driving the development of fibrotic strictures in CD. The present study aimed to identify the mucosal markers associated with stricturing complications by examining the differences in the gene expression profiles of two patient cohorts: Patients diagnosed with inflammatory CD (n=12) and patients with stricturing CD (n=9). For each patient, a paired sample of inflamed and uninflamed mucosa was isolated and assessed by quantitative PCR using a large panel of genes associated with inflammatory bowel disease. The presents study revealed a significantly increased level of four genes in the mucosa of patients with strictures compared with the inflammatory pattern of the disease: Formyl-peptide receptor 1 [P=0.019; fold change (FC)=11.6], C-C chemokine receptor type 1 (P=0.035; FC=5.44), IFN-γ-inducible protein 10 (P=0.037; FC=3.8) and C-C chemokine ligand 25 (P=0.048; FC=3.56). The augmented expression of these four genes in the CD stricturing phenotype, if confirmed in larger cohorts of patients, could help elucidate the mechanisms leading to disease-associated complications.

Aims. An 84-year-old patient with a history of high blood pressure presented to the emergency room with lower abdominal pain and haematochezia. Methods. Clinical:hemodynamically stable. Biological: WBC 32700/microL, Hb=8.1 g/dL, PLT = 321 000/microL, INR=1.23, CRP = 292 mg/L. CTscan: no contrast extravasation in the digestive tract, infrarenal aortic aneurysm (130 mm cranio-caudal), with parietal thrombus plus a retroaortic abscess with stenosis of the inferior vena cava. Vascular surgery consultation: no surgical indication ->admission to the gastroenterology department. Emergency upper GI endoscopy: adherent clot in the fornix, stasis fluid. 60 cm rectosigmoidoscopy: mucosal lesions suggestive of ischemic colitis. Reevaluation after 12 h: WBC = 26 000/microL, hemoglobin = 7.1 g/dL Results. Re-evaluation of the CT-scan: suspicion of an aorto-duodenal fistula. Second upper GI endoscopy: gastric mucosa, bulb and D2 lined with fresh blood. On withdrawal, an infrapapillary lesion suggestive for an aortoenteric fistula. Duodenoscopesecond look:an erosion with a diameter of 10 mm with a deep punctate hole: most likely aortoenteric fistula. The patient was transferred to cardio-vascular surgery: double-layer duodenorrhaphy and aorto-aortic interposition of a silver Dacron prosthesis were done. Conclusion. The particularity of the case was represented by the rare cause of haemorrhage with difficult diagnosis. The approach and treatment required a multidisciplinary team and a good collaboration. The patient was discharged after 17 days with a good general condition. [ABSTRACT FROM AUTHOR]

Aims. Variceal bleeding is a common and severe cause of hospitalization in cirrhotic patients. We analyzed how the COVID-19 waves modified the outcome of the patients compared to COVID-19 extra-wave intervals. Methods. We retrospectively included all patients hospitalized between March 2020 and December 2021 for variceal bleeding. They were separated in 2 categories: hospitalizations during COVID-19 extrawaves period and the COVID-19 waves. Variables like sex, age, hemoglobin at presentation, endoscopic timing, hemostatic methods, transfusion necessity, duration of hospitalization and mortality were analyzed. Results. Out of 76 patients (2020-2021), 20patients were hospitalized during the COVID-19 waves. The median age did not differ significantly across groups (61 years [IQR: 52-65] vs 58years [IQR: 44-64]), 59 patients being male and 17 being female. The number of admissions for variceal bleeding and gastroscopy requirement and timing were similar regardless of the studied period (p > 0.05). Median hemoglobin admission values were significantly lower in the following subgroups: patients in whom gastroscopy was performed in less than 6 hours or more than 12 hours (p = 0.045) and patients requiring PRBC transfusion (p = 0.018). There were also no differences in duration of hospitalization and mortality between the two studied periods (p>0.05). Conclusions. The number of patients remained relatively constant in both periods. We found no differences in the management and outcomes of patients with variceal bleeding throughout the COVID pandemic. Our results might be influenced by the low number of patients and need confirmation on larger cohorts. [ABSTRACT FROM AUTHOR]
