✦ Synopsis


A patient with ataxia telangiectasia was treated with recombinant interleukin-2 (rIL-2) and the resulting immunological effects evaluated. The patient lacked IL-2 production, and immnnoglobulin synthesis was also impaired. Treatment with IL-2 selectively increased serum IgM without any significant side effects. Therapy also restored B-cell function in vitro, IgM production as well as the proliferative response to Staphylococcus aureus strain Cowan I. These results suggest that IL-2 treatment may correct both T-cell and B-cell defects.
