FOXP3 gene (locus Xp11. 23-q13. 3)[2, 4, 9], leading to failure in immune tolerance. Haematopoietic stem cell transplantation (HSCT) is the only definitive therapy and, even if its success is inconstant, it is considered to be the treatment of choice for the disease [6, 8, 10]. On the other hand, just two cases have been reported as surviving the first decade with a severe form of the disease without HSCT [5, 7]. A 1-month-old male was referred to our department for a severe eczema (Fig. 1), intractable mucous diarrhoea and failure to thrive. Extensive investigations ruled out a severe combined immunodeficiency (SCID). Symptoms were controlled with intravenous immunoglobulin, cyclosporin A, steroids and total parenteral nutrition (TPN)(Fig. 2). During his second year of life, he developed autoimmune diabetes, autoimmune haemolytic anaemia (AHA), inflammatory interstitial pneumonia, alopecia and thyroiditis. Due to the unsatisfactory response to prednisone, oral betamethasone was prescribed, with a dramatically greater efficacy at an equipotent dosage. A bone marrow transplantation was refused by the parents. Flares of dermatitis, AHA and pneumonia occurred after every cold and required increasing doses of steroids, antibiotics and oxygen administration. Cyclosporin A (10 mg/kg/day) did not allow a reduction of steroids and the child developed a Cushing-like aspect. An experimental treatment with fludarabine followed by the infusion of autologous lymphocytes treated in vitro with vincristine and prednisone was repeated twice, allowing a prolonged reduction of steroid dosage (0.5–0.25 mg/day of betamethasone) and fairly good clinical improvement with less frequent and less intense reactivation of symptoms.
