How might collagenous gastritis be treated?

To our knowledge, there is currently no establishted method of treatment for collagenous gastritis (CG).[1][2] Various therapies have been attempted with some success.[3]

Some individuals with CG and celiac disease have reportedly had some relief of symptoms with gluten-free diets; however, this might have been related to the celiac disease rather than the CG itself. Budesonide has been used to treat collagenous colitis (a related disorder), and some symptomatic relief in individuals with CG treated with this medication has also been reported.[3] In a recent case report, symptoms of a young adult with CG stabilized with treatment of 10 mg of rabeprazole taken in the morning and evening before eating. Once his condition stabilized the dose was reduced to 10 mg once a day before breakfast. With this treatment and lifestyle improvements this patient's symptoms greatly improved.[2] As a result, it has been suggested that proton pump inhibitors, like rabeprazole, may be beneficial in treating this disorder.[2]
