Nitric oxide and indicators of oxidative stress in patients with exacerbation of chronic pancreatitis

: The aim of the study was to compare the level of nitric oxide to clinical and laboratory criteria for acute CP, and indicators of oxidative stress in CP. A total of 129 patients with CP (96 males and 33 females), mean age 46,9 +/- 9,2 years, were distributed to the groups with uncomplicated and complicated course. A study of nitric oxide in the blood as an additional criterion for acute CP. Found it significantly increased in patients with CP compared with control values. The content of nitric oxide in the blood during uncomplicated CP was 149,07 +/- 15,4 umol/l, with complicated course increased to 211,5 +/- 17,7 umol/l, which is significantly higher than that in uncomplicated CP (p = 0,042). A significant increase of NO level in the amplification of pain intensity (10-point analogue scale), and also obtained a direct correlation between these criteria (r = 0,69, p = 0,01). Received a significant increase in levels of nitric oxide with an increase in pancreas head size, revealed a direct correlation between these parameters (r = 0,59, p = 0,04). The obtained results allowed using nitric oxide as a criterion of acute HP. For diagnostic levels of nitric oxide made its rise above 120 mmol/liter. Sensitivity and specificity improvement of nitric oxide above 120 umol/L were 97% and 57% respectively when compared with the pain syndrome and 42% and 62% respectively when compared to pancreas head size. Were studied AAO and MDA indices. A significant increase in MDA (t = 2,58, p = 0,012), indicating that activation of LPO. There was a significant increase of MDA in the amplification of the intensity of pain, and also obtained a direct correlation between these criteria (r = 0,30, p = 0,03). Identified a direct correlation between levels of MDA and nitric oxide (r = 0,63, p = 0,01). Study of the level of nitric oxide can be used as an additional criterion of exacerbation of CP. In patients with CP enhanced LPO processes, as evidenced by the increase of MDA in patients with high levels of nitric oxide in the blood. Growth of LP may be an additional pathophysiological factor amplifying damaged pancreas.
