Evaluation of serum neutrophil gelatinase-associated lipocalin (NGAL), asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) levels, and their relations with disease type and activity in inflammatory bowel diseases

Serum NGAL, ADMA and SMDA levels are increased in patients with IBD, and serum NGAL, ADMA and SMDA concentrations are significantly higher in active IBD patients than inactive IBD patients. Our results suggest these biomarkers may serve in estimating IBD activity and severity.
