OBJECTIVE: To study the change in endogenous hydrogen sulfide (H2S) in patients with acute pancreatitis and its relationship to coagulation function.
METHODS: A prospective case control study was conducted. Forty patients with mild acute pancreatitis (MAP group) and 40 with severe acute pancreatitis (SAP group) admitted to Yiwu Central Hospital in Zhejiang Province from December 2002 to March 2015 were enrolled. Forty healthy persons served as control (healthy control group). Blood was collected to determine the levels of H2S, blood coagulation factor Ⅷ (FⅧ), von Willebrand factor (vWF), plasminogen (PLG), antithrombin (AT), platelet count (PLT), tissue factor (TF), tumor necrosis factor-α (TNF-α), and protease activated receptor-1 (PAR-1). The correlations among the above parameters were analyzed.
RESULTS: There was no statistical significance in sex, age, body weight and time of disease among three groups, indicating it was comparable among the groups. Compared with healthy control group, the levels of H2S, FⅧ, vWF, TF, TNF-α, and PAR-1 in MAP and SAP groups were significantly elevated [H2S (μmol/L): 67.42±6.34, 112.47±12.69 vs. 42.57±4.18, FⅧ: (67.5±5.8)%, (82.3±4.7)% vs. (57.2±6.4)%, vWF: (112.6±9.7)%, (142.5±12.5)% vs. (76.4±8.2)%, TF (ng/L): 45.27±4.34, 64.76±6.25 vs. 18.15±1.89, TNF-α (ng/L): 197.67±13.62, 324.72±25.54 vs. 20.08±2.57, PAR-1 (fluorescence intensity): 32.16±4.43, 56.12±7.07 vs. 12.27±2.12, all P < 0.01], and PLG and AT activity were significantly decreased [PLG: (52.4±4.7)%, (36.7±3.2)% vs. (62.1±5.6)%, AT: (43.2±6.9)%, (35.5±5.4)% vs. (53.6±6.1)%, all P < 0.01]. The changes in the parameters in SAP group were more remarkable than those in MAP group (all P < 0.01). PLT in SAP group was significantly lower than that in healthy control and MAP groups (×109/L: 8.5±1.1 vs. 15.7±2.8, 12.4±1.9, both P < 0.01). H2S was positively correlated with FⅧ, vWF, TF, TNF-α, and PAR-1 (r value was 0.56, 0.61, 0.72, 0.66, 0.64, respectively, all P < 0.01), and it was negatively correlated with PLG and AT (r value was -0.64, -0.57, both P < 0.01).
CONCLUSION: As an inflammatory factor, endogenous H2S deteriorates coagulation function in patients with acute pancreatitis by up-regulating TF, TNF-α, and PAR-1.
