OBJECTIVE Infection by Helicobacter pylori has been epidemiologically linked to some extradigestive conditions, including ischemic heart disease. Diabetic patients are an at-risk population for cardiovascular and thrombo-occlusive cerebral disease. The aim of the study was to examine a possible relationship between H. pylori infection and cardiovascular or(More)
BACKGROUND Although the clinical manifestations of chronic urticaria (CU) are similar in most patients, a variety of factors should be taken into consideration. In general, the cause of CU cannot be determined in most patients, and it is considered idiopathic. In the past several years, relationships between some patients with CU and hepatitis C or(More)
BACKGROUND Helicobacter pylori infection is associated with low-grade gastric MALT lymphoma, and available data support that the eradication of the H. pylori can cause histological regression of the lymphoma. PATIENTS AND METHODS Nine patients with low-grade gastric MALT lymphoma were treated with amoxicillin, metronidazole, and omeprazole for 14 days in(More)
We report a patient with cirrhosis and hepatopulmonary syndrome. This syndrome is an entity characterized by anomalies in the arterial oxygenation in patients with chronic hepatic disease and/or portal hypertension and demonstration of pulmonary vasodilatation (PV) in absence of primary cardiac or pulmonary disease. We show that the finding of PV with(More)
BACKGROUND/AIMS To establish rapid urease test utility for initial diagnosis of Helicobacter pylori infection in gastric ulcer patients and to determine the best site for sampling for gastric biopsies. METHODOLOGY Seventy consecutive gastric ulcer patients were prospectively studied. All these patients underwent three biopsies from both antrum and body(More)
Allicin and allyl-methyl plus methyl-allyl thiosulfinate from acetonic garlic extracts (AGE) have been isolated by high-performance liquid chromatography. These compounds have shown inhibition of the in vitro growth of Helicobacter pylori (Hp), the bacterium responsible for serious gastric diseases such as ulcers and even gastric cancer. A chromatographic(More)
BACKGROUND Serology is a good alternative, minimally invasive, diagnostic and screening test for Helicobacter pylori infection. Several immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) commercial kits have been evaluated. Information on IgA ELISAs is relatively poor, and on the combined use of IgG and IgA ELISAs very scarce. OBJECTIVE We(More)
We made a retrospective study of 233 episodes of spontaneous bacterial peritonitis that were treated at our Service between January 1980 and September 1996 in order to analyze the clinical presentation, microbiological data, possible pathogenic factors, treatment, and evolution of this clinical entity. Ascites, abdominal pain, and fever were the most(More)
BACKGROUND Localized low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma can regress after Helicobacter pylori eradication, but IgV(H) gene monoclonality may persist. We studied the long-term histological and molecular follow-up of 24 patients and the possible association of t(11;18) with the persistent monoclonality. PATIENTS AND METHODS(More)
OBJECTIVE The epidemiology of Helicobacter pylori infection is still under investigation, and the exact source of infection and its mode of transmission are still unknown. The purpose of this prospective study was to determine whether medical professionals in Spain, especially gastroenterologists and gastrointestinal endoscopists, have a higher prevalence(More)
