ABSTRACT

BACKGROUND/AIMS: Helicobacter pylori infection is the most common cause of gastroduodenal diseases. The role H. pylori eradication in functional dyspepsia patients is contradictory. We performed this study to determine the effects of H. pylori eradication in functional dyspepsia patients with respect to physiological and histological parameters including esophageal sphincter functions. METHODOLOGY: We studied 20 functional dyspepsia patients, whose H. pylori infection was confirmed by histology and urease test. We also confirmed eradication using the same methods after three months. We performed 24-hour esophageal pH monitoring, esophageal manometry, meal stimulated gastrin release test and measured dyspepsia severity score and gastric emptying time before and three months after eradication. Eradication regimen consisted of omeprazol 20 mg b.i.d., clarithromycin 500 mg b.i.d. and metranidazol 500 mg b.i.d., for two weeks. Gastric inflammation and H. pylori density within biopsy samples from the antrum (n = 4), corpus (n = 4), cardia (n = 2), fundus (n = 2), duodenum (n = 2) and distal esophagus (n = 1) were assessed. RESULTS: Dyspepsia severity score (P < 0.001), meal stimulated gastrin levels, upper (P = 0.01) and lower (P = 0.06) sphincter pressures were decreased after eradication irrespective of gastric histology; but gastric emptying times (P = 0.87) and pH < 4.5% reflux (P = 0.91) were not changed significantly. CONCLUSIONS: H. pylori eradication results in decreased esophageal sphincter pressures irrespective of gastric histology in functional dyspepsia patients. These decreases are not associated with increased objective reflux or reflux symptomatology. The clinical significance of these finding deserves further evaluations.

ABSTRACT

Anemia and thrombocytopenia in a patient with parvovirus B-19 and hepatitis C infection is reported. A seven month-pregnant 20 year-old patient had been first found to be anemic and thrombocytopenic 40 days before admission to our hospital and she had been given methylprednisolone and red cell transfusions. She gave birth to a healthy baby after only eight months of pregnancy. Ten days after delivery she was admitted to our hospital because of anemia and thrombocytopenia which did not respond to treatment. On admission, the blood count showed hemoglobin 8.1 g/dL, hematocrit 23.7%, white blood cells 11,200/microL, platelets 1000/microL, and reticulocytes 0.6%. Bone marrow smear and biopsy revealed erythroblastopenia and the absence of megakaryocytes. Liver enzymes were also high (alanine aminotransferase 1469 Units/L and aspartate aminotransferase 981 Units/L). In serologic studies PVB-19 IgM was found to be positive and hepatitis C virus RNA was detected. Red cell and platelet values returned to normal levels after cessation of methylprednisolone and concomitantly PVB-19 IgG was found positive in association with IgM in repeated determinations. PVB-19 was thought to be responsible for both anemia and thrombocytopenia.
