Association of polymorphisms of IL and CD14 genes with acute severe pancreatitis and septic shock.
OBJECTIVE
To investigate IL-1beta+3 594 in the 5th intron, IL-10-1 082 and CD14-159 polymorphisms in patients with acute pancreatitis (AP) and septic shock.


METHODS
The study included 215 patients (109 with acute severe pancreatitis (SAP), 106 with acute mild pancreatitis (MAP)) and 116 healthy volunteers. Genomic DNA was prepared from peripheral blood leukocytes. Genotypes and allele frequencies were determined in patients and healthy controls using restriction fragment length polymorphism analysis of PCR products.


RESULTS
The frequencies of IL-1beta+3 594T, IL-10-1082G and CD14-159T allele were similar in patients with mild or severe pancreatitis and in controls. Within SAP patients, no significant differences were found in the allele distribution examined when etiology was studied again. Patients with septic shock showed a significantly higher prevalence of IL-10-1082G allele than those without shock (chi2= 5.921, P = 0.015).


CONCLUSIONS
IL-10-1082G plays an important role in the susceptibility of SAP patients to septic shock. Genetic factors are not important in determination of disease severity or susceptibility to AP.
