. Background and reasonAt present, the infection of dengue fever patients increases every year. The minor symptoms of complications on the various systems to severe symptoms and even death. The complications is the key.The incidence of bleeding, such as bleeding under the skin, gums, or gastrointestinal tract. Which some have bleeding and death. Pathogenesis of bleeding in patients with dengue hemorrhagic fever caused by low platelet.Platelet dysfunction (platelet dysfunction) coronary dysfunction (vasculopathy) the coagulopathy (coagulopathy). From work experience, education, research and articles. Found that patients infected with dengue fever several items.Activated partial thromboplastin time (APTT) alone, without the prothrombin time (PT) usually causes prolonged APTT caused by asymmetry of the system. And coagulation fibrinolysis which caused attention that the reason why patients with dengue hemorrhagic fever with prolonged APTT.A preliminary study on laboratory and found that in patients infected with dengue prolonged APTT only found fibrinogen level. Lower and lower heparin rise, can cause hypothesis that there are heparin-like substance.
.Objective to find out the causes of the hardening of the blood prolonged APTT in patients with dengue, what caused it. Especially that about which there are heparin-like substance or
.Methods: study patients with dengue fever admitted in the hospital.Siriraj Hospital. Since 14 may 2557 - 13 may 2558 causes that make the hardening of the blood prolonged APTT study. Prospective (cohort) study analyzed using SPSS version 17
.The study in patients with dengue hemorrhagic fever all 8 people (male = 4 female = 4) the average age 31 years showed aPTT prolong 5 (62.5%), average value. APTT = 34.41 sec (minimum, maximum 27.60 sec = = 48.00 sec) found in patients 5. Further examination showed low level fibrinogen 2 (40%) the fibrinogen level = 92.9 150.6, mg / dl. The average fibrinogen level = 232.70 mg / dl detected with heparin higher number 4 (80%) mean heparin level = 0.22 unit (minimum = 0 unit maximum = 0.5 unit) to analyze the relationship between the level of blood aPTT hardening and heparin level. Use Pearson correlation found that the significant (2-tailed) = 0.037 (P < 0.05) relationship between
.Conclusion patients with dengue hemorrhagic fever with unusual blood clotting aPTT prolong alone were found to have significantly higher levels heparin level real
