Abstract
Severe acute pancreatitis can lead to systemic complications. Here, we explore the mechanisms based on our previous study associated with the deregulation of heme oxygenase-1 (HO-1) and development of severe acute pancreatitis. Acute pancreatitis patients (n = 135) and age- and sex-matched healthy controls (n = 108) were studied. The polymerase chain reaction products were analyzed with an ABI 3130 genetic analyzer and GeneMapper software. A short allele was defined ≤27 dinucleotide (GT) repeats, whereas a long allele was defined >27 GT. Levels of 12 different cytokines in blood serum were measured by enzyme-linked immunosorbent assay. All samples in this study were consistently stored in -80°C. Patients with the long long genotype expressed E-selectin and vascular cell adhesion molecule-1 at statistically significantly higher levels in serum compared with short short genotype or short long genotypes. Vascular cell adhesion molecule-1 and E-selectin serum levels significantly correlate with the total allele length of the HO-1 promoter region. Polymorphism of the GT repeats in the HO-1 promoter region may be a risk factor for developing acute necrotizing pancreatitis due to deregulation of the immune response.
