Correlation between 13C-urea breath test value and severity of gastric mucosal lesions

AIM: To explore the correlation between ¹³C-urea breath test (UBT) value and severity of gastric mucosal lesions.

METHODS: Seventy-four patients who underwent the ¹³C-UBT and gastroscopy within 1 week were included in the study. The severity of gastric mucosal lesions was graded pathologically. The correlation between ¹³C-UBT value and the score of gastric mucosal lesions was analyzed.

RESULTS: ¹³C- UBT value was positively correlated with the severity of chronic inflammation (r = 0.9958, P = 0.0001), atrophy (r = 0.2498, P = 0.0318) and intestinal metaplasia (r = 0.2784, P = 0.02) in the gastric antrum mucosa, but not positively with that of active gastritis in the same site (r = 0.1979, P = 0.09). ¹³C-UBT value was positively correlated with the severity of active inflammation (r = 0.6223, P = 0.0001), chronic inflammation (r = 0.5480, P = 0.0001) and atrophy (r = 0.6014, P = 0.0001) in the gastric angle mucosa, but not positively with that of intestinal metaplasia in the same site (r = 0.1308, P = 0.27). ¹³C- UBT value was not positively correlated with the severity of active inflammation (r = 0.2039, P = 0.08), chronic inflammation (r = 0.0966, P = 0.41), atrophy (r = 0.1369, P = 0.24), or intestinal metaplasia (r = 0.1837, P = 0.12) in the gastric body mucosa. ¹³C-UBT value was positively correlated with the severity of active inflammation (r = 0.9958, P = 0.0001), chronic inflammation (r = 0.9843, P = 0.0001), atrophy (r = 0.9921, P = 0.0001) and intestinal metaplasia (r = 0.9934, P = 0.0001) in the whole gastric mucosa.

CONCLUSION: ¹³C-UBT value positively correlates with severity of gastric mucosal lesions. ¹³C-UBT quantitative detection may be used clinically to assess the severity of gastric mucosal lesions.
