Abstract: Dengue hemorrhagic fever (DHF) is an epidemic viral disease. The exact mechanism attributable to platelet and vascular dysfunctions is still obscure. Plasma 6-keto-PGF1a (6KPGF1), the stable metabolite of PGI2 was determined in 60 DHF patients and in 11 non-DHF (NDHF) patients with fever of over 38.5 degrees C to compare with that of 33 normal children (NC) in the same age group (2-15 years). Among 60 DHF patients, 32 had blood obtained during impending shock, whereas blood samples of the remainder were taken during normotension. Their plasma 6 KPGF1 values (mean +/- SE) were 201.06 +/- 12.42 and 132.87 +/- 13.08 pg/ml respectively. All patients had serology positive for acute dengue viral infection. The plasma 6 KPGF1 (mean +/- SE) of 33 NC and 11 - NDHF subjects were 149.82 +/- 4.93 and 108.69 +/- 14.53 respectively. The plasma 6KPGF1 levels of 32 DHF patients with impending shock were significantly higher than those of 28 normotensive DHF patients (p less than 0.005), 33 NC (p less than 0.005) and 11 - NDHF patients (p less than 0.005). However the levels in 28 normotensive DHF patients are not statistically different from the values of 33 NC and 11 - NDHF patients. It is concluded that there is a tendency of excessive PGI2 production in DHF patients during hypotensive crisis.
