Abstract

fetched live from OpenAlex

PURPOSE OF REVIEW: To summarize this year's relevant literature on the causes and mechanisms of autoimmune gastritis. RECENT FINDINGS: It is increasingly recognized that parietal cell antibodies, previously assumed exclusive to autoimmune gastritis, are associated with Helicobacter pylori infection. Successful H. pylori eradication with antibiotic treatment decreases antiparietal cell antibodies. Interestingly, vitamin B(12) deficiency, previously associated with autoimmune gastritis, is increasingly described in the elderly, irrespective of H. pylori status. Autoimmune gastritis that mostly affects patients of Scandinavian descent, was reported this year from China, and corpus predominant gastritis (autoimmune associated) was reported from Japan. It is difficult to evaluate the role played by genetics, increased use of proton pump inhibitors, and H. pylori infection, as current patient work-up does not regularly include screening for parietal cell and intrinsic-factor antibodies. As these clinicopathologic changes are seen in both H. pylori-positive patients, and in H. pylori-naïve patients, the debate continues for mechanisms involved in H. pylori-naïve patients. SUMMARY: The clinical features commonly associated with autoimmune gastritis are increasingly seen in the elderly, irrespective of H. pylori status. Though some patients are genetically predisposed, long-term proton pump inhibitor use increases the prevalence of clinicopathologic features irrespective of genetic tendency.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
