Serum adiponectin levels are significantly lower in NAFLD patients with elevated liver enzymes. Non-alcoholic steatohepatitis patients show lower levels of adiponectin with higher grades of inflammation.

Helicobacter pylori is now regarded as a major gastroduodenal pathogen that is etiologically linked with duodenal and gastric disease. It has been suggested recently as an important factor for nongastroenterologic conditions such as coronary heart disease and diabetes mellitus. In this study, we planned to investigate the prevalence of H. pylori in diabetic patients and to evaluate five different diagnostic tests. Group I consisted of 67 patients with type II diabetes mellitus and seventy-three aged-matched health people served as control in group II. Group I was divided in two subgroups with good (Group IA) and poor (Group IB) glycemic control. H. pylori was diagnosed by five different tests: 1) biopsy, 2) culture, 3) gram staining, 4) imprint cytology and 5) brushing cytology. The usefulness of each test for each group was statistically compared. There was a higher prevalence for H. pylori in diabetic patients. This study showed that two positive out of five tests was most reliable for predicting the H. pylori in diabetic and nondiabetic patients. In conclusion, the prevalence of H. pylori is high in diabetic patients. Peristaltic activity, and impaired nonspecific immunity must be evaluated as risk factors in diabetics. We recommend that the 'gold standard' should be regarded as two positive out of these five different tests.

Pantoprazole-based 1-week triple therapy was well tolerated and the ulcer healing rate was high (85%). Relatively low H. pylori eradication rates may be attributed to rising antibiotic resistance over recent years. A large scale, comparative study with other PPI-based regimens is warranted based on the results of this open study with the pantoprazole-based regimen.

Thrombocytopenia is a frequent complication of cirrhosis. Its pathogenesis is not well known, but it has been suggested that splenic congestion induced by portal hypertension may be a major contributory factor. However, the available data regarding the effect of portal decompression either by surgical shunts or transjugular intrahepatic portosystemic shunt (TIPS) on peripheral platelet count in cirrhotics is conflicting. We studied the effects of TIPS on platelet count and mean platelet volume, following a successful TIPS placement. The platelet count had a tendency to decrease but was not statistically significant (120,100 +/- 72,100/mm3 before TIPS vs 99,800 +/- 51,400/mm3 after TIPS). The mean platelet volume remained essentially unchanged (9.8 +/- 1.5 fL before TIPS and 9.9 +/- 1.5 fL after TIPS). These results confirm that TIPS has an unpredictable effect on platelet count in cirrhotic patients with thrombocytopenia. The lack of a consistent increase in the peripheral mean platelet volume following TIPS placement suggests that TIPS is unable to significantly enhance the release of platelets sequestered in the splenic compartment in portal hypertension.
