[Immunological disorders in a patient with Whitaker syndrome (author's transl)].

: Some immunological parameters have been examinated in a 13-year-old girl with Whitaker syndrome and in her closest blood-relatives. Absolute and percentage values of T and B lyphocytes were normal, whereas mitogen responsiveness was over normal range before therapy had begun. This phenomen did not appear if the cultures were carried out in presence of autologous serum. Neutrophil function was defective in responsiveness to chemotactic stimulation, but NBT reduction as well as bactericidal activity were normal. Defects both in mitogen responsiveness and chemotaxis have been pointed out in the parents and in the patient's twin brother. The immunologic disorders observed are discussed in the light of the clinical and functional pecularities of Whitaker's syndrome.
