Multicenter Study Comparative StudyAn assessment of the management of acute bleeding varices: a multicenter prospective member-based study.
Bleeding from esophagogastric varices is a major complication of portal hypertension. Despite recent practice guidelines for the management of bleeding esophageal or gastric varices, the widespread application of these measures by gastroenterologists has not been evaluated. The purpose of this study was to continue the concept of membership-based research within diverse practice settings by expanding the American College of Gastroenterology (ACG) GI Bleeding Registry to assess the management and outcome of acute variceal bleeding. ⋯ Acute variceal hemorrhage occurs more often in patients with Child's B and C cirrhosis. Endoscopic banding is the most common single endoscopic intervention. Adjunctive pharmacotherapy is prevalent acutely and after stabilization. Both morbidity and mortality may be lower than reported in previous studies.

Randomized Controlled Trial Comparative Study Clinical TrialVitamin E and vitamin C treatment improves fibrosis in patients with nonalcoholic steatohepatitis.
Nonalcoholic steatohepatitis (NASH) is a common cause of liver disease. Although usually indolent, this disease can progress to cirrhosis in some patients. There is currently no proven medical therapy for the treatment of NASH. The aim of our study was to evaluate the efficacy of combination alpha-tocopherol (vitamin E) and vitamin C in reducing histologic inflammation and fibrosis. ⋯ Forty-five patients completed 6 months of therapy without significant side effects. Vitamin treatment resulted in a statistically significant improvement in fibrosis score (p=0.002). No changes were noted in inflammation with treatment. Vitamin E and vitamin C, in the doses used in this study, were well tolerated and were effective in improving fibrosis scores in NASH patients. No improvement in necroinflammatory activity or ALT was seen with this combination of drug therapy. A larger, multicenter, longer-term trial with vitamin E and vitamin C seems to be warranted.

Randomized Controlled Trial Comparative Study Clinical TrialNurse-administered propofol versus midazolam and meperidine for upper endoscopy in cirrhotic patients.
Upper GI endoscopy is often performed in patients with chronic liver disease to screen for esophageal and gastric varices. Propofol is currently under evaluation as an alternative to the combination of midazolam and meperidine for sedation during endoscopic procedures. The purpose of this study was to compare nurse-administered propofol to midazolam and meperidine for sedation in patients with chronic liver disease undergoing diagnostic upper GI endoscopy. ⋯ Propofol sedation administered by registered nurses in the setting of adequate patient monitoring is efficacious and well tolerated in patients with liver disease who are undergoing variceal screening by upper endoscopy. Patients were more satisfied with the quality of sedation, and return to baseline function was usually sooner compared to results achieved with midazolam/meperidine. Propofol offers advantages over meperidine/midazolam in cirrhotic patients.

Comparative StudyOverlapping upper and lower gastrointestinal symptoms in irritable bowel syndrome patients with constipation or diarrhea.
Distinguishing between irritable bowel syndrome (IBS) and functional dyspepsia can be challenging because of the variations in symptom patterns, which commonly overlap. However, the overlap is poorly quantified, and it is equally uncertain whether symptom patterns differ in subgroups of IBS arbitrarily defined by primary bowel patterns of constipation (IBS-C) and diarrhea (IBS-D). We aimed to determine and to compare the distribution of GI symptoms, both, upper and lower, among IBS-C and IBS-D patients. ⋯ Upper GI symptoms consistent with functional dyspepsia were more frequent in IBS-C. Although there was considerable overlap of upper and lower GI symptoms in patients with IBS-C and IBS-D, the former had more frequent lower abdominal pain and bloating.
