There is currently no one superior agent used to treat childhood TA. However, individual centres have provided treatment protocols with a high success rate.
In one study, 6 patients between the ages of 12 to 17 years were treated using the following:
|1. If the disease was on only one side of the diaphragm with no pulmonary disease||Oral steroids and oral MTX (12.5mg/m2/week)|
|2. If the disease was more widespread||Oral steroids and oral CYC (1.5-1.7 mg/kg/day) for a total of 12 weeks (max total dose of 150mg/kg) followed by oral MTX as above (12.5mg/m2/week) for 12 to 18 months|
|3. Life threatening disease||Pulse methylprednisolone given for 3 consecutive days|
|4. In patients whose APRs were normal||Oral prednisone started at 1 mg/kg/day for 4 weeks tapered to a maintenance dosage of 5 to 10 mg/day by 12 weeks.|
In the last visit of this study, 5 patients were all found to be symptom-free. During the course of this study, one patient died and one patient had a relapse stenosis of the graft after one year (though found symptom-free later). All patients were still on low-dose alternate-day corticosteroids as of June 1, 2006.
