Clinical Presentation and Cardiovascular Outcome in Complete versus Incomplete Kawasaki Disease

Objective: To compare the demographic, clinical, and laboratory features of incomplete and complete presentations of Kawasaki disease. Methods: A retrospective review of the electronic case records between January 2000 and December 2015 in a tertiary care referral center of Sohar, Oman. Results: 31 out of 64 children (48.4%) had incomplete presentation. Children with incomplete presentation had higher incidence of skin rash, lymphadenopathy and conjunctivitis. They took a longer time to show clinical response to intravenous immunoglobulin [mean (SD) 52.6 (17.4) h vs 40.1 (16.4) h, P=0.005], and had prolonged hospitalization [mean (SD) 6.2 (2.5) d vs 4.6 (1.7) d, P=0.009]. Conclusions: Children with incomplete presentation of Kawasaki disease tend to have prolonged hospitalization but short- and long-term coronary outcomes appear to be similar.
