30 mg/kg/dose (Max: 1 gram/dose) IV or IM once daily for 1 to 3 days. High-dose pulse steroids may be considered as an alternative to a second infusion of IVIG or for retreatment of patients who have had recurrent or recrudescent fever after additional IVIG, but should not be used as routine primary therapy with IVIG in patients with Kawasaki disease. Corticosteroid treatment has been shown to shorten the duration of fever in patients with IVIG-refractory Kawasaki disease or patients at high risk for IVIG-refractory disease. A reduction in the frequency and severity of coronary artery lesions has also been reported with pulse dose methylprednisolone treatment.
There is some evidence that sun exposure can accelerate steroid-induced skin atrophy, the development of which can be limited by protecting the skin, particularly the face and arms, from the sun. Daily use of a broad-spectrum sunscreen (UVB and UVA block) and appropriate protective clothing is recommended. 10 , 12 - 14 Patients on corticosteroids should also be encouraged to regularly use moisturisers on their arms and legs, as these may reduce bruising and tearing of the skin from minor trauma. 11 Evidence suggests that topical tretinoin can increase the epidermal thickness of sun-damaged atrophic skin, but long-term use may be necessary. 14 In dermatological practice, topical retinoids are used to help reverse skin atrophy caused by sun exposure or corticosteroid use.
