Serum phospholipase A2 and pulmonary changes in acute fulminant pancreatitis.
Twenty-three patients with acute fulminant pancreatitis were studied. The diagnosis was confirmed at laparotomy in every case. Blood samples for the assay of phospholipase A2 were collected for 14 days, and the pulmonary status of the patients was followed by monitoring the blood gases and the inspired oxygen fraction and studying a derived variable, the alveolar to arterial oxygen tension difference--the arterial oxygen tension ratio (A--aDo2/PaO2). The serum phospholipase A2 activities correlated with the changes in pulmonary function and with the outcome of the disease. Eight patients succumbed and they showed higher phospholipase A2 activities and A--aDo2/PaO2 ratios than the five patients who survived after major complications and the ten patients who survived without major complications. The results suggest that in acute fulminant pancreatitis serum phospholipase A2 activity correlates with the severity of the pulmonary changes. Furthermore, it seems to reflect the prognosis.
