Objectives. To determine the type of chemiluminescent reaction depending on acute pancreatitis severity.
Methods. The patients (n=60, an average age made up 44 years) with an acute pancreatitis in the enzymatic phase were enrolled in the study. The diagnosis was made on the basis of clinical laboratory indices as well as on the data of instrumental investigations, using for estimation an integral disease severity scale and a patient’s general condition. Registering generation rate of active oxygen forms was carried out by means of the method of luminol-dependent chemiluminescence; the indices of spontaneous and induced reaction were estimated.
Results. Activation of the lipid peroxidation processes occurred at mild form of an acute pancreatitis has been established resulting in the elevation of generation of active metabolites, and in particular, of active oxygen forms. The increase of the maximal value of a chemiluminescence by 3,97 fold and the area under the curve by 2,56 fold has been registered against the background of reducing time-to-peak response. In case of moderate forms of acute pancreatitis the changes occurred in chemiluminescent reaction characterized it as hyperoxemic one. The elevation of the reaction intensity by 9,51 times was established against the background of the reducing time-to-peak response by 3,11 fold. A severe form of the disease was characterized by the generation reduction of active oxygen forms against the background of the expressed endointoxication and characterized the chemiluminescent reaction as hypoxemic one. Decrease in the maximal value of a chemiluminescence by 9,30 fold the curve symmetry and reducing time-to-peak response was registered against the background of the elevation area under the curve at a spontaneous reaction by 1,39 fold.
Conclusion. The conducted study confirmed that the changes of chemiluminescent reaction may serve as additional criteria for severity evaluation of an acute pancreatitis. At mild and moderate forms of an acute pancreatitis, the processes of hyperproduction of active oxygen forms predominated. Severe acute pancreatitis is characterized by the production reduction of active oxygen forms that is manifested by hypoxemic type of chemiluminescent reaction.
