title: Effect of early hemofiltration on pro- and anti-inflammatory responses and multiple organ failure in severe acute pancreatitis.
abstract: The effects of early hemofiltration on the serum levels of cytokines, pro- and anti-inflammatory balance and organ function in pigs with severe acute pancreatits (SAP) were studied. SAP pig model was induced by retrograde injection of artificial bile into the pancreatic duct. The pigs were randomly divided into SAP hemofiltration treatment group (HF group, n=8) and SAP non-hemofiltration treatment group (NHF group, n=8). In the HF group, the animals were subjected to high-volume and zero-balance hemofiltration therapy. The results showed that as compared with NHF group, MAP, CVP and PaO2/FiO2 were significantly increased (P<0.01), while HR, urinary protein content, serum ALT level, pulmonary coefficient and lung wet/dry ratio obviously decreased (P<0.05) in HF group. Under a light microscope, the pulmonary histologic scoring was lower that in HF group (P<0.01) and the lesions of renal and liver tissues were milder. However, there was no significant difference in the pancreatic histologic scoring between the two groups. Six h after establishment of the model, the serum levels of TNF-alpha, IL-1beta were lower, while the IL-10/ TNF-alpha ratio was higher in HF group (all P<0.05). It was suggested that early hemofiltration could effectively remove the serum cytokines TNF-alpha and IL-1beta in SAP pigs, elevate the ratio of IL-10/TNF-alpha, improve hemodynamics and alleviate the lesions of lung, kidney and liver tissues.
