Predictors of Mortality in Long-Term Follow-Up of Patients with Terminal Alcoholic Cirrhosis: Is It Time to Accept Remodeled Scores?

OBJECTIVE: To identify the prognostic score that is the best predictor of outcome in patients hospitalized with decompensated liver cirrhosis. MATERIAL AND METHODS: In this prospective study, 126 patients were enrolled and followed up for 29 months. For each patient, prognostic scores were calculated; these included the Child-Turcotte-Pugh score (CTP score), CTP creatinine-modified I score, CTP creatinine-modified II score, Model for End-Stage Liver Disease (MELD score), MELD model for end-stage liver disease sodium-modified score, Integrated MELD score, updated MELD score, United Kingdom MELD, and the MELD score remodeled by serum sodium index (MESO index). Cox regression analysis was used to assess the ability of each of the scores for predicting mortality in patients with alcoholic cirrhosis. Their discriminatory ability was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS: The updated MELD score had the highest predictive value (3.29) among the tested scores (95% CI: 2.26-4.78). ROC curve analysis demonstrated that the MELD score of 22.50 (AUC = 0.914, 95% CI: 0.849-0.978; p < 0.001) had the best discriminative ability for identifying patients with a high risk of mortality; the next best was the MESO index of 16.00 (AUC = 0.912, 95% CI: 0.847-0.978; p < 0.001). CONCLUSION: The risk of mortality was highest in patients with the highest updated MELD score, and those with MELD scores >22.50 and a MESO index >16.00.

The activities of acid DNase and 5'nucleotidase in erosive reflux esophagitis and Barrett's epithelium.

BACKGROUND/AIMS: The study examines the relationship between activity of acid DNase and 5'nucleotidase (5'NT) and histological changes in reflux esophagitis. METHODOLOGY: Thirty-three patients were examined, 15 of whom with mild esophagitis, 12 with severe esophagitis and 6 with Barrett's epithelium. Patients were classified into 3 groups, according to Ismail-Beigi histological criteria: mild esophagitis group (ME); severe esophagitis group (SE); Barrett's esophagitis group (BE). DNase and 5'NT levels were measured biochemically both in healthy and injured tissue samples. RESULTS: Difference of acid DNase and 5'NT activity in healthy tissue versus injured tissue samples was the lowest in ME group: 0.55±4.47 U/g for acid DNase and 11.56±37.11 U/g for 5'NT, the difference increased to 4.43±1.64 U/g for acid DNase and 105.57±54.11 U/g for 5'NT in the SE group, while 6.07±2.92 U/g for acid DNase and 109.83±14.02 U/g for 5'NT as the highest levels were measured in the BE group. Difference in BE group is statistically significantly higher (p <0.05) compared to the ME group, confirmed by ANOVA with Dunnett's post hoc test. CONCLUSIONS: The study shows significant decrease of apotosis level that is detectable even before metaplasia was morphologically defined.

Clinical diagnostic problems associated with cecal ameboma: case report and review of the literature.

Amebiasis is uncommon in developed countries. Its clinical presentation can be variable and non-specific, and the diagnosis can be easily overlooked. Among the wide variety of clinicopathologic manifestations of the intestinal amebiasis, amebomas occur rarely, resulting from the formation of annular colonic granulation tissue, usually in the cecum or ascending colon. This report describes the case of a 65-year-old female who presented with a painful mass in the right hypochondrium and intermittent abdominal cramping, associated with defecation difficulty. Radiologic examination depicted thickening of the cecal wall and its ring-like stenosis in association with a mesenteric reaction. Because of concentric thickening of the cecal wall and the mass-like appearance, a preliminary clinical diagnosis of cecal cancer was made, and the patient was referred to the Clinic for surgical treatment. Histologic examination of the surgical specimen after segmental colectomy confirmed the diagnosis of cecal ameboma. The authors conclude that multiple granulomas of amebic trophozoites can be better recognized after PAS staining, and that the pathognomonic feature of protozoa-ingested red blood cells was also seen in the surgical specimen.
