Subjects meeting the study inclusion/exclusion criteria will be randomized equally to receive either:
1. Prednisone 0.5 mg kg/day for 6-months (MAX dose 30 mg per day) or
2. Methotrexate 15-20 mg po, sc, or IM once a week for 6-months + Folic Acid 2 mg OD for 6 months + Prednisone 20 mg day for 1 month, then 10 mg OD for 1 month, then 5 mg OD for one month then STOP
