We report a 38-year-old patient affected by refractory adult onset Still's disease who achieved a prolonged remission following CD34-selected ABMT. The conditioning regimen was based on the use of CY and anti-thymocyte globulin. A 3.0 and 2.0 log reduction of T (CD3+) and B (CD19+) lymphocytes, respectively, was obtained using a Ceprate device to select CD34+ cells from PBSC.

In the pre-transplant period (1994-1998) the patient had a chronic persistent disease course with frequent and recurrent systemic articular flares and loss of some functional abilities, despite daily prednisone, pulses of CY and immunosuppressive therapy (CYA or MTX). At the time of ABMT the patient had become non-ambulatory.

Within 3 weeks of ABMT the patient showed a marked decrease in joint swelling, and morning stiffness. Joint pain and systemic symptoms disappeared, the patient was able to walk and run and gained general well being. ESR, C-reactive protein and WBC count were significantly decreased, while Hb level increased.

This partial remission persisted for at least 1 year after ABMT, although at 15 months of follow-up a reappearance of moderate synovitis in the knees and wrists was noted.

Our data further showed that both patient BM microenvironment and stem-progenitor cell function (as assessed by LTC-IC assay) were damaged even 1 year after CD34-selected ABMT, suggesting that the persistence of these alterations could have facilitated the favorable outcome of the disease following ABMT.
