Chronic Atrophic Gastritis
Conditions
Brief summary
To evaluate the efficacy and safety of umbilical cord blood mononuclear cells in the treatment of chronic atrophic gastritis.
Interventions
2 times gastric submucosal injection of mononuclear cells (10\^8) at 1 month interval
Orally delivered tablets for 7 months. Take it according to the instructions.

Patients without contraindications to submucosal injection of umbilical cord blood derived mononuclear cells.
Exclusion criteria
1. Patients with gastric ulcer, erosive gastritis, active upper gastrointestinal bleeding, gastric varices, or other gastric tumors. 2. Patients who are taking or have taken proton pump inhibitors, antibiotics, glucocorticoids, nonsteroidal anti-inflammatory drugs and immunosuppressants in the last six months. 3.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline OLGA/OLGIM stages of gastric mucosa | At the first, seventh and thirteenth month of treatment | Assessment of OLGA/OLGIM stages by GI pathologists. The obtained biopsy specimens will be scored using visual analogue scale (0, 1, 2, 3 points for none, mild, moderate and severe, respectively) to evaluate gastroatrophy and gastrointestinal metaplasia |
| Change from baseline gastric mucosal status under gastroscope | At the first, seventh and thirteenth month of treatment | Assessment of Kimura-Takemoto classification by endoscopy. The variation of atrophy can reflect the extent and degree of atrophy. The severity of atrophy increases gradually with C1-C2-C3-O1-O2-O3. Cases of closed-type gastric mucosa atrophy have an atrophic boundary between the fundic mucosa and the pyloric mucosa in the antrum or less curvature of the gastric body. Cases of open-type gastric mucosa atrophy have an atrophic boundary in the lateral wall or greater curvature of the gastric body. C, closed; O, open |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline blood test result | At the first, seventh and thirteenth month of treatment | Assessment of Gastrin-17 and Pepsinogen I/II |
| Incidence of adverse reactions | Through follow-up period completion, an average of 1 year | Assessment of incidence of adverse reactions |
