Histopathological Findings in Adult Patients With Dyspepsia and Their Association With Helicobacter pylori Infection

BACKGROUND

Helicobacter pylori infection is prevalent among Saudi adults and has been linked to gastric cancer and other tumor-like conditions. We aimed to explore the pathological characteristics of endoscopic gastric biopsies among symptomatic adult Saudi patients and their relation to H. pylori infection.

RESULTS

Among 151 gastric biopsies, gastritis was detected in 97 (64.2%) cases, chronic active gastritis in 26 patients (17.2%), duodenitis in 20 (13.2%) patients, and total metaplasia in 14 (9.3%) patients. H. pylori was detected in 83 cases (55%), with a recurrence or reinfection rate of 9.8%. The patients with H. pylori infection were considerably young (median age: 34 (IQR: 15) vs. 35.5 (IQR: 11), p = 0.024) and had a low frequency of epigastric pain (78.3% vs. 91.2%, p = 0.031), reflux/regurgitation (7.2% vs. 20.6%, p = 0.016), and dysphagia (4.85% vs. 14.7%, p = 0.037). However, they exhibited a higher incidence of chronic active gastritis (96.2% vs. 3.8%, p < 0.001) and intestinal metaplasia (85.7% vs. 14.3%, p = 0.015). Young age (OR = 1.09, 95% CI = 1.02-1.16, p = 0.011) and H. pylori infection (OR = 30.85, 95% CI = 3.26-291.60, p = 0.003) were identified as a positive predictor of intestinal metaplasia while heartburn (OR = 0.08, 95% CI = 0.01-0.58, p = 0.012) was a negative predictor.

CONCLUSION

H. pylori infection is prevalent among Saudi adults experiencing upper gastrointestinal symptoms and is associated with intestinal metaplasia. Infection rate and intestinal metaplasia were higher in patients with milder symptoms. Therefore, screening for H. pylori is highly recommended for Saudi individuals with upper gastrointestinal symptoms. Old age and H. pylori infection were identified as positive predictors of intestinal metaplasia, emphasizing the importance of early detection and management of H. pylori infection in the Saudi population.

Urinary Orosomucoid - 2 and Soluble CD14 as Potential Biomarkers for Assessment of Disease Activity in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is the most common inflammatory joint disease leading to severe disability and premature mortality. Current blood biomarkers for assessing RA activity are invasive and are not highly sensitive or specific to changes in disease activity. Therefore, there is a need for new biomarkers that can accurately indicate disease activity. The present study evaluated the use of urinary orosomucoid (ORM) - 2 and soluble CD14 (sCD14) as non-invasive biomarkers for precise assessment of disease activity of RA, in order to improve treatment outcomes in RA patients. The study included 36 female patients with RA, were divided into three groups of mild, moderate and severe disease activity according to disease activity score 28 (DAS 28) based on erythrocyte sedimentation rate (ESR) and were compared to control group. Urinary levels of ORM-2 and sCD14 were measured by ELISA. All patients showed significant increase in urinary ORM-2 and sCD14 levels in comparison to controls. There were significant positive correlations of urinary ORM-2 and sCD14 levels with DAS28score and also with the conventional blood biomarkers (C- reactive protein (CRP) and ESR). The receiver operating characteristic curve analysis revealed that both urinary ORM-2 and sCD14 have higher predictive value for disease activity than CRP and ESR. In conclusion, Urinary ORM-2 and sCD14 levels were increased in patients with RA and were correlated with the disease activity. Thus, the urinary biomarkers might be able to replace blood measures for RA activity as they could provide non-invasive and precise assessment of disease activity in RA patients.
