Poor response to Methotrexate, AZA, and Etanercept. Most patients are doing better on low dose prednisone+ MMF+ Hydroxychloroquine. 2/14 (14%) needed a bilateral lung transplant. |

Good response to pulse steroids followed by MMF+ low dose oral steroids. C2-was treated with repeated pulse steroids, oral high and low dose steroids and now with adalimumab and methotrexate for arthritis. |
