Abstract
Context
Intravenous immunoglobulin (IVIG) resistance and coronary artery lesions (CALs) prediction are pivotal topic of interests in Kawasaki disease (KD). However, data on the predictive value of lipid profile for both IVIG resistance and CALs are limited.
Purpose
To investigate the predictive validity of lipid profile for IVIG resistance and CALs in KD.
Design
Prospective cohort study.
Setting
West China Second University Hospital.
Patients
363 KD patients were divided into the initial IVIG-resistant group and initial IVIG-responsive group; repeated IVIG-resistant group and repeated IVIG-responsive group; CAL+ group and CAL- group.
Main Outcome Measures
Validity of lipid profile in predicting IVIG resistance and CALs.
Results
TG was significantly higher whereas TC, HDL-C, LDL-C as well as Apo A were significantly lower in initial IVIG-resistant subjects, with cut-off values of 1.625 mmol/L, 3.255 mmol/L, 0.475 mmol/L, and 1.965 mmol/L and 0.665 g/L, yielding sensitivities of 52%, 70%, 52%, 61%, 50%, and specificities of 68%, 53%, 78%, 71%, 81%, respectively. TC, LDL-C, and Apo A levels were significantly lower in repeated IVIG-resistant subjects, with cut-off values of 3.20 mmol/L, 1.78 mmol/L, 0.605 g/L, producing sensitivities of 91%, 70%, 57% and specificities of 55%, 67%, 70%, respectively. Apo-A level was significantly lower in the CAL group, with cut-off value of 0.805g/L, yielding sensitivity of 66% and specificity of 54%.
Conclusions
Lipid profiles were significantly dysregulated in KD patients suffering IVIG resistance and CALs. Some of them, such as LDL-c and Apo-A, could serve as complementary laboratory markers for predicting both IVIG resistance and CALs.
