In H pylori-associated atrophy,

hypochlorhydria has a role in www.selleckchem.com/products/shp099-dihydrochloride.html iron deficiency (ID) through changes in the physiology of iron-complex absorption. The aims were to evaluate the association between H pylori-associated hypochlorhydria and ID in children.\n\nMethods Symptomatic children (n=123) were prospectively enrolled. Blood, gastric juice and gastric biopsies were taken, respectively, for haematological analyses, pH assessment and H pylori determination, and duodenal biopsies for exclusion of coeliac disease. Stool samples were collected for parasitology/microbiology. Thirteen children were excluded following parasitology and duodenal histopathology, and five due to impaired blood analysis.\n\nResults Ten children were hypochlorhydric (pH>4) and 33 were H pylori positive. In H pylori-positive children with pH>4 (n=6) serum iron and transferrin saturation levels % were significantly lower (p<0.01) than H pylori-positive children with pH <= 4. No differences in ferritin, or total iron binding capacity, were observed. In H pylori-negative children with pH>4, iron and transferrin saturation were not significantly different from children with pH <= 4.\n\nConclusions

Low serum iron and transferrin in childhood H pylori infection is associated with hypochlorhydria. In uninfected children, hypochlorhydria was not associated with altered serum iron parameters, indicating a combination of H pylori infection and/or inflammation, and IPI-145 hypochlorhydria has a role in the aetiology of ID. Although H pylori-associated hypochlorhydria is transient during acute gastritis, this alters iron homeostasis with clinical impact in developing countries with a high H pylori prevalence.”
“Carcinosarcoma is an uncommon biphasic malignant neoplasm consisting of both carcinomatous and sarcomatous components. We report a case of an 84-year-old male with multiple carcinosarcomas occurring in the esophagus and stomach. Endoscopically, a bulky pedunculated polypoid lesion was observed in

the middle of the esophagus and a huge discoid lesion in the lesser curvature. The patient received esophageal endoscopic mucosal resection, and the Selleckchem GSK1838705A specimen measured 4×2.5×1.5 cm. Microscopically, the esophageal tumor consisted of several polymorphic spindle cells mixed with squamous cells, while the gastric biopsies revealed carcinomatous cells with evident abnormal karyokinesis and polymorphous spindle cells. Immunohistochemically, the resected tumor stained positively for the epithelial markers, epithelial membrane antigen (EMA) and cytokeratin 19 (CK 19), and the mesenchymal markers, smooth muscle actin (SMA) and vimentin. The gastric lesion stained positively for CK AE1/AE3, actin and vimentin, but was negative for EMA. Both lesions were positive for neuron specific enolase (NSE), demonstrating neuroendocrine differentiation. The patient succumbed seven months after being discharged from hospital.
