Abstract: Objective To investigate the clinical manifestations, diagnosis and treatment of Kawasaki disease complicated with pancreatitis and low T3 syndrome. Methods The clinical data of Kawasaki disease complicated with pancreatitis and low T3 syndrome in one child were retrospectively analyzed, and the relevant literature was reviewed. Results A 4-year-old girl presented with Kawasaki disease and pancreatitis was treated at our facility. During her stay, she developed Kawasaki disease shock syndrome, low T3 syndrome, and gamma globulin resistance. After two times of gamma globulin and hormone therapy, she had no fever, but she still constantly complained abdominal pain. Through the treatment of fasting, water prohibition, suppression of pancreatic enzyme secretion, and gastrointestinal nutrition by nose jejunum tube implantation, the child was recovered and discharged. The prognosis of the child was good after six months’ follow-up. Conclusion Kawasaki disease complicated with pancreatitis and low T3 syndrome suggests a critical condition requiring early identification, intervention and follow-up of echocardiography and thyroid function.
