Serum leucine-rich alpha-2 glycoprotein levels for predicting active ultrasonographic findings in intestinal lesions of patients with Crohn’s disease in clinical remission

This study aimed to investigate the cutoff value of leucine-rich alpha-2 glycoprotein (LRG) in predicting active intestinal ultrasonography (IUS) findings in patients with Crohn’s disease (CD) in clinical remission. Data were retrospectively collected from patients with CD evaluated using LRG and un...

Sumario:This study aimed to investigate the cutoff value of leucine-rich alpha-2 glycoprotein (LRG) in predicting active intestinal ultrasonography (IUS) findings in patients with Crohn’s disease (CD) in clinical remission. Data were retrospectively collected from patients with CD evaluated using LRG and undergoing IUS from September 2020 to August 2022. Patients with a Harvey–Bradshaw Index of ≤4 were included and those who underwent intestinal resection were excluded. Bowel wall thickness and stratification and blood flow signal using superb microvascular imaging (SMI) were used to assess ultrasonography findings. SMI signals were categorized into 4 grades following the Limberg score. Receiver operating characteristic curves were constructed and the area under the curve was calculated to determine the LRG cutoff values for predicting active IUS findings and were compared with those of C-reactive protein. This study included 213 patients. The LRG cutoff values to predict active bowel wall thickness, loss of bowel wall stratification, and SMI of ≥1, ≥2, and 3 were 14.6 μg/mL, 14.6 μg/mL, 14.6 μg/mL, 14.6 μg/mL, and 16.9 μg/mL, respectively, with significantly higher areas under the curve in SMI of ≥1 and 3 than in C-reactive protein. The best LRG cutoff value for predicting active IUS findings was 14.6 μg/mL in patients with CD in clinical remission, suggesting that LRG is better than C-reactive protein for detecting active IUS findings in CD.
