Esomeprazole with aspirin versus clopidogrel for prevention of recurrent gastrointestinal ulcer complications.

Background And Aims: The role of clopidogrel in patients at risk for gastrointestinal complications is uncertain, although it has been recommended for patients who have gastrointestinal intolerance to aspirin. We tested the hypothesis that clopidogrel is as effective as esomeprazole and aspirin in preventing recurrences of ulcer complications.

Methods: This was a prospective, double-blind, randomized, controlled study of 170 patients who developed ulcer bleeding after the use of low-dose aspirin between November 2002 and January 2005.

Hepatitis B virus infection in dialysis patients.

Hepatitis B virus (HBV) infection remains a major issue among dialysis patients. It is associated with a high risk of hepatic complication. The liver disease runs a unique clinical course in dialysis patients, as it can progress with modest hepatic inflammation and prominent fibrosis.

Hepatitis B associated fulminant polyarteritis nodosa: successful treatment with pulse cyclophosphamide, prednisolone and lamivudine following emergency surgery.

For hepatitis B virus associated polyarteritis nodosa, alpha interferon and plasma exchanges have been proposed to be the first-line treatment. We report a case of hepatitis B surface antigen (HBsAg)-positive fulminant polyarteritis nodosa with predominant gastrointestinal involvement who showed good response to pulse cyclophosphamide, prednisolone, and lamivudine therapy. The patient, a 22-year-old man, presented with a short history of epigastric pain.
