Polymorphisms in the mannose‐binding lectin gene as determinants of age‐defined risk of coronary artery lesions in Kawasaki disease

Abstract

Our findings indicate that MBL has an ambiguous role in Kawasaki disease and contributes differently to the pathophysiologic development of CALs, being protective in infants but potentially harmful in patients of older age. The data also imply that the standard treatment of intravenous immunoglobulins to reduce the development of lesions may not be as effective in the very young as it is in the older patients. For the very young, alternative or adjuvant treatment may be indicated, particularly in infants who are MBL-deficient.
