Hypercoagulation and elevation of blood triglycerides are characteristics of Kawasaki disease

Area of Science:

• Pediatric Cardiology
• Biochemistry
• Hematology

Background:

• Kawasaki disease (KD) poses significant risks for cardiovascular damage in children.
• Hypertriglyceridemia and hypercholesteremia are known cardiovascular risk factors, yet their role in KD remains understudied.
• Limited research exists on blood lipid metabolism alterations in pediatric patients with KD.

Purpose of the Study:

• To investigate and analyze blood lipid profiles and coagulation status in children diagnosed with Kawasaki disease.
• To compare lipid metabolism and coagulation markers between KD patients, healthy children, and those with bacterial infections.

Main Methods:

• Plasma and serum triglyceride and cholesterol levels were measured in 20 KD patients, 10 healthy children (HC), and 10 children with bacterial infections (BT).
• Lipid species were profiled using electrospray ionization mass spectrometry.
• Blood coagulation parameters were analyzed, with statistical analysis performed using one-way ANOVA.

Main Results:

• Significantly elevated plasma triglyceride (TG) levels were observed in KD patients, while serum TG levels showed no significant change.
• All 19 identified TG molecular species were increased in KD and BT patients, with a more pronounced elevation in KD.
• Major molecular species of plasma phosphotidylcholine and lyso-phosphotidylcholine were decreased in KD and BT patients.
• KD patients exhibited pronounced hypercoagulation.

Conclusions:

• The findings suggest hyperlipidemia, particularly elevated triglycerides, contributes to hypercoagulation in KD, increasing cardiovascular damage risk.
• Evaluating blood lipid levels in severe KD cases offers valuable insights for guiding treatment and predicting patient prognosis.
• Further investigation into lipid metabolism in KD is warranted for improved clinical management.
