| Abstract: | We report a 2.3-year-old girl with complete lack of adenosine deaminase (ADA) activity who presented with severe atopic dermatitis and insulin-dependent diabetes mellitus but only mild recurrent infections. Abnormalities of immune function included profound depletion of CD8+ lymphocytes, hyperimmunoglobulinaemia E, and very low in vitro proliferative response to mitogens. Treatment with polyethylene glycol-conjugated ADA was followed by rapid amelioration of clinical and immunological conditions. The immunological and clinical features of this child suggest that the clinical spectrum of ADA deficiency may be broader than originally supposed. |
