Clinical Pathologic Profiles of Reveal Age-Specific Peaking with Concomitant Chronic Gastric Inflammation, Robust Immunity, and Tissue Alterations Implying Potential Predisposition to Malignancy in Ha'il, Saudi Arabia.

() is a significant global health issue causing chronic gastritis, peptic ulcers, and gastric malignancies. Unfortunately, many, particularly in the Middle East, continue to exhibit alarming rates of prevalence. This study aimed to elucidate local epidemiological patterns of and examine its histopathological impact on the gastric mucosa. This retrospective-cross-sectional study included 805 symptomatic adults (329 males, 476 females) who underwent endoscopic evaluation at King Salman Hospital, Ha'il, Saudi Arabia. Biopsies from the antrum and body were processed using routine formalin fixation and paraffin embedding. Staining with hematoxylin-eosin (H&E) and Giemsa permitted assessment of chronic gastritis and detection of . Data were evaluated by IBM SPSS (version 23, IBM Corp., Armonk, NY) for associations among infection, histopathology, and patient characteristics. A total of 727 (90.3%) were -positive with marginally higher rates in females (91.2%) than males (89.0%). Infection spanned all age groups, reaching 100% in males aged 60-80 years. Overall chronic GI complications were identified in 726 (99.9%), with chronic gastritis being the most profound histopathologically (19.3%). Lymphoid aggregates in 93.0% biopsies reflected a pronounced immune response. Advanced lesions, including metaplasia (0.8%), atrophy (0.3%), and lymphoma (0.1%), were uncommon, though indicative of potential malignant progression. Despite both sexes exhibiting universal symptoms of gastritis, dyspepsia, and heartburn, there were no statistically significant gender-based differences ( > 0.05); specifically, post- signs such as vomiting, nausea, weight loss, bleeding or hematemesis occurred equally in all. Histopathology consistently revealed chronic active gastritis with glandular distortion, lymphoplasmacytic infiltration, and occasional mucosal erosions. Giemsa staining further confirmed abundant spiral shapes underscoring a high bacterial load. These findings highlight the age-specific persistently elevating rates of significantly associated with chronic gastric inflammatory complications. Although advanced gastric lesions remain rare, reflecting regional epidemiology, early screening, and sleeve treatment efforts, the potential for malignant transformation makes it imperative for continued vigorous eradication, therapy, and vigilant follow-up to avert severe disease outcomes.
