Comparison of sucralfate and ranitidine in the treatment of chronic nonerosive gastritis. A randomized, multicenter trial

Clinical Practice Guideline for Gastritis in Korea

Gastritis is a disease characterized by inflammation of the gastric mucosa. It is very common and has various classification systems such as the updated Sydney system. As there is a lot of evidence that Helicobacter pylori infection is associated with the development of gastric cancer and that gastric cancer can be prevented by eradication, H. pylori gastritis has been emphasized recently. The incidence rate of gastric cancer in Korea is the highest in the world, and due to the spread of screening endoscopy, atrophic gastritis and intestinal metaplasia are commonly diagnosed in the general population. However, there have been no clinical guidelines developed in Korea for these lesions. Therefore, this clinical guideline has been developed by the Korean College of Helicobacter and Upper Gastrointestinal Research for important topics that are frequently encountered in clinical situations related to gastritis. Evidence-based guidelines were developed through systematic review and de novo processes, and eight recommendations were made for eight key questions. This guideline needs to be periodically revised according to the needs of clinical practice or as important evidence about this issue is published in the future.

Is there still a role for sucralfate in the treatment of gastritis?

The endoscopic diagnosis of gastritis is usually made when a patient develops symptoms and undergoes an upper gastrointestinal endoscopy. There are often obvious aetiological causes such as smoking, alcohol Helicobacter pylori infection or drug treatment. Lifestyle changes can sometimes improve symptoms but often patients will be treated with a proton pump inhibitor. The stomach mucosa produces a protective mucous to prevent damage cause by gastric acid and exogenous agents can disrupt this layer. Repair of this protective layer can be enhanced by reduction in gastric acid secretion using H2 receptor antagonist or proton pump inhibitors or by cytoprotective drugs such as misoprostol, sucralfate, aluminium ions or bismuth subsalts. Sucralfate is a complex polymer which at a low pH changes its chemical configuration and binds to serum protein to form a protective layer protecting the mucosa against further injury. Cytoprotective drugs were the first line treatment for peptic disease including gastritis for many years but since the launch of cimetidine in 1976 and the subsequent launch of omeprazole in 1988, their use has slowly declined. First line treatment for patients with symptomatic gastritis after removal of potential causative factors is likely to be a proton pump inhibitor in 2019. This is despite the fact that there is some evidence that sucralfate is superior than a H2 receptor antagonist in the endoscopic healing rates in patients with gastritis. The logical treatment choice in patients with resistance symptoms is a combination of a proton pump inhibitor and sucralfate but evidence is lacking. Until such evidence is available In the meantime, we would suggest that there is a role for sucralfate in the treatment of intransigent gastritis and that mucosal protection should be considered even ahead of acid suppression given its favourable safety and toxicity profile.

Troxipide in the management of gastritis: a randomized comparative trial in general practice

Background. A trial of empirical acid-suppressive therapy is the usual practice for most patients with symptoms of gastritis in primary care. Aim. To assess the relative efficacy of Troxipide and Ranitidine in patients with endoscopic gastritis over a four-week period. Methods. In all, 142 patients were randomized to Troxipide (100 mg tid) or Ranitidine (150 mg bid) for a period of four weeks. The severity of the signs of endoscopic gastritis at baseline and week 4 using a four-point scale and the subjective symptom severity at baseline and week 2 & week 4 using a Visual analog scale (VAS) were documented. Results. Troxipide was found to be superior to Ranitidine for both, the complete resolution and improvement of endoscopic gastritis. Higher proportion of patients showed complete healing of erosions (88.14%), oozing (96.77%), and edema (93.88%) with Troxipide as compared to Ranitidine (P < .01). Patients receiving Troxipide also showed a greater improvement in the VAS scores for abdominal pain, bloating, and heartburn (P < .01). Both the drugs were found to be well tolerated. Conclusion. In patients with endoscopic gastritis, Troxipide, with its superior rate of improvement, resolution of signs, and subjective clinical symptoms, can be considered as an alternative to the commonly used antisecretory agents.

Post-cholecystectomy alkaline reactive gastritis: a randomized trial comparing sucralfate versus rabeprazole or no treatment

OBJECTIVE

At present there are no well-established pharmacological approaches in the management of post-cholecystectomy alkaline reactive gastritis. The aim of this study was to assess the effect of sucralfate versus rabeprazole or no treatment on dyspeptic symptoms and endoscopic/histological signs in a population of patients with a history of cholecystectomy and evidence of alkaline reactive gastritis.

METHODS

Sixty dyspeptic patients fulfilling the following criteria of inclusion took part in this study: (1) a history of cholecystectomy; (2) no use of anti-inflammatory steroidal and non-steroidal drugs, or abuse of alcohol; (3) evidence of abundant gastric bile reflux at endoscopy; (4) endoscopic signs of chronic gastritis; (5) histological signs of chronic gastritis; and (6) absence of Helicobacter pylori infection. Dyspeptic symptoms were evaluated by means of a self-administered validated questionnaire. Patients included in the study were randomly assigned to one of three treatment groups for 3 months: sucralfate, rabeprazole, observation. Patients were re-evaluated at the end of the treatment.

RESULTS

Sucralfate and rabeprazole therapies were both able to significantly reduce epigastric pain, heartburn, bloating and halitosis. Endoscopic/histological signs were lower in both treatment groups compared to the observation group.

CONCLUSION

Both sucralfate and rabeprazole therapies are effective treatment options in the patients with alkaline gastritis when compared with observation.

Follow-up of endoscopic gastritis after healing with sucralfate or an H2-receptor antagonist

48 patients in whom previous endoscopic signs of chronic gastritis had been abolished by treatment with either 1 g sucralfate three times daily or 40 mg famotidine at night were followed up for 3 months without further therapy. Cumulative endoscopic relapse rates at 3 months were 21.7% in the sucralfate group and 57.1% in the famotidine group (p = 0.017). All patients with endoscopic recurrence of gastritis also reported recurrence of dyspeptic symptoms of various degrees. Most patients with endoscopic relapse had persisting histologic gastritis, but up to 67% of subjects with histologic gastritis at the time of initial endoscopic healing did not have subsequent endoscopic or clinical recurrence. It is concluded that gastritis, especially if histologically active, tends to recur quickly after endoscopic healing and that early relapses are significantly more frequent after treatment with an H2 blocker than after sucralfate.
