Familial Kawasaki disease and acute glomerulonephritis: case report and review of literature.

We report two siblings, a 6-year-old boy and his 4-year-old sister who were admitted with fever for 15 days and features of Kawasaki disease. After admission to the hospital, both patients developed red urine and headache. Blood pressure was found to be high in relation to blood pressure percentiles for both patients. Urine analysis showed the features of acute glomerulonephritis with normal urine output and renal function. A multidisciplinary discussion with the paediatric nephrologist, rheumatologist and cardiologist was conducted, and intravenous immunoglobulins, aspirin, pulsed methylprednisolone and antihypertensive therapy were added to the treatment plan with a good outcome.
