Abstract
Intravenous immune globulins (IVIG) are increasingly used in Kawasaki-like cases possibly related to coronavirus disease 2019 (COVID-19), generally with striking clinical response. We describe a teenager presenting febrile cholestasis, along with coronary aneurysm and other criteria fulfilling incomplete Kawasaki disease. The girl was treated with high dose acetylsalicylic acid and IVIG transfusion. Laboratory work-up revealed hepatitis antibodies. However, this result was obtained after IVIG and is considered as passively transferred IgG’s from blood donors. Especially during COVID-19 pandemic, clinicians should be familiar with unusual Kawasaki presentations as febrile cholestasis, as well as inconclusive serology after the desired IVIG therapy.
