Abstract 210: Kawasaki Disease in Patients Older Than 10-years Old in a Children’s Hospital In Mexico City
Background: Kawasaki Disease (KD) is an acute febrile illness characterized by systemic vasculitis of unknown etiology. Cardiac sequelae, such as coronary artery aneurysms (CAA), are one of the most important aspects of this disease. Actually KD is most frequently presented in children younger than 5-years old.
Objective: To describe the clinical and laboratory features, cardiac sequelae and outcome in children older than 10-years old with KD who were attended at the Instituto Nacional de Pediatría in Mexico City.
Methods: An observational, descriptive, retrospective and transversal case study. We reviewed the medical records of patients older than 10-years diagnosed with KD from August 1995 to May 2014, and analyzed gender, age, clinical manifestations, hemoglobin, leucocyte count, platelet count, ESR, CRP, albumin, sodium, potassium, AST, ASL, time from the onset of the symptoms to diagnosis, treatment used, the development of CAA and outcome in the acute phase of the disease.
Results: We studied 18 cases of KD in patients older than 10-years old, 72.2% (13 of 18) were male with a mean age of 154 months (range 120 to 200). The time from the onset of the fever to diagnosis was 10.6 ± 5.8 days, (range 3 to 21 days). Skin lesions were the most common manifestation of KD and cervical lymphadenopathy was the least common clinical feature. 2 patients presented with KD shock syndrome. Complete KD was diagnosed in only 50% (9 of 18) of our cases. 16 patients received IVGG, 2 patients required a second GGIV dose and 10 patients also received steroids. 6 of 18 patients (30%) developed CAA. There were no deaths in our group.
Conclusions: KD in patients older than 10-years old represent a clinical challenge because in the majority of the cases they presented with an atypical clinical picture which contribute to a delayed diagnosis. Also there is an increased risk of developing cardiac complications and CAA in this group of patients.
