Plasma 6-keto-PGF1 alpha, thromboxane B2 and PGE2 during diabetic ketoacidosis

In 10 patients admitted to hospital with diabetic ketoacidosis plasma prostanoids 6-keto-PGF alpha, thromboxane B2 and PGE2 were studied before treatment and following recovery. During ketoacidosis the median plasma 6-keto-PGF1 alpha and PGE2 were significantly increased compared to those of a normal reference group: 5.2 pg/ml and 3.9 pg/ml versus 1.7 pg/ml and 0.4 pg/ml (p less than 0.01 and p less than 0.05). In response to therapy both prostanoids decreased significantly towards a normal level, 6-keto-PGF1 alpha: 0.5 pg/ml p less than 0.01 and PGE2: 0.08 p less than 0.05 respectively. The changes in plasma 6-keto-PGF1 alpha were negatively correlated to changes in pH, rho: -0.7788 p = 0.0135, whereas the changes in PGE2 were positively correlated to serum creatinine at admittance, rho: 0.6976, p = 0.0368 and to the amount of intravenous fluid and insulin used during treatment, rho: 0.7500 p = 0.0126 and rho: 0.8424, p = 0.0023 respectively. Plasma thromboxane B2 concentrations were not elevated and did not change after treatment of the ketoacidosis.
