chondroitin-sulfates and Gastritis

Gastritis is an inflammation of the gastric mucosa. In this study, we investigated the efficacy of a medical device, Esoxx®, based on hyaluronic acid and chondroitin sulfate on gastritis-related upper abdominal pain/discomfort and endoscopic features. Fifty patients, affected by gastritis, were randomised to receive the medical device or placebo. The primary endpoint was the medical device efficacy on upper abdominal pain/discomfort associated with gastritis and measured by Visual Analogue Scale (VAS). The secondary endpoints were the efficacy of the medical device on gastritis-related mucosal erosions, blood oozing, and hyperemia (redness)/edema, as assessed by endoscopy, and the patients' rating of their compliance with the treatments. A significant reduction in VAS pain was observed in the treatment group after a 5-week treatment, if compared with placebo (p < 0.001). In summary, administration of a medical device, based on hyaluronic acid and chondroitin sulfate, improves gastritis-related upper abdominal pain/discomfort and decreases mucosal erosions, blood oozing, and hyperemia (redness)/edema at 5-week follow-up in patients affected by gastritis.

The sulfated glycosaminoglycan (SGAG) composition of gastric mucosa from 24 patients with chronic superficial gastritis, 2 patients with adenocarcinoma and 36 normal subjects is reported. The mucosa was obtained by endoscopic biopsy and after histopathological examination the SGAG were extracted and characterized. Three different SGAG were isolated: chondroitin 4,6-sulfate, dermatan sulfate and heparan sulfate. Their relative concentrations for the different groups were submitted to analysis of variance by Scheffe's method. Different SGAG compositions were observed in two gastric regions (antrum and body), in chronic superficial gastritis, in adenocarcinoma and in two age groups (less than 40 years and greater than 40 years). These and other results suggest that these macromolecules might be involved in the processes of cell division and aging.
