Positive effect of erythrocyte-delivered dexamethasone in ataxia-telangiectasia Objective: Ataxia-telangiectasia (AT) is a rare, devastating neurodegenerative disease presenting with early-onset ataxia, oculocutaneous telangiectasia, immunodeficiency, radiosensitivity, and proneness to cancer. In a previous phase 2 study, we showed that 6 monthly infusions of autol-ogous erythrocytes loaded with dexamethasone (EryDex; EryDel, Urbino, Italy) were effective in improving neurologic impairment in young patients with AT. The present article reports the results of the extension of this study for an additional 24-month period. Methods: After the end of the first trial, 4 patients continued to be treated with monthly EryDex infusions for an additional 24 months, and their clinical outcome was compared with that of 7 age-matched patients who stopped the treatment after the first 6 infusions. The protocol included serial assessment of ataxia (by International Cooperative Ataxia Rating Scale) and adap-tive behavior (by Vineland Adaptive Behavior Scales) and clinical and laboratory tests revealing treatment- and steroid-dependent adverse effects, if present
