Histiocytosis X--an immune deficiency disease? Studies on antibody-dependent monocyte-mediated cytotoxicity

Br J Dermatol. 1981 Jul;105(1):13-8. doi: 10.1111/j.1365-2133.1981.tb00877.x.


Six children with histiocytosis X, all in clinical remission, were investigated for antibody-dependent cytotoxicity mediated by monocytes and neutrophils. Monocytes demonstrated a reduced cytotoxicity and a normal Fc receptor activity. Judged by light microscopy the monocytes were normal. Preincubation with the patient's serum did not influence the cytotoxicity of normal monocytes. Neutrophils from patients with histiocytosis X showed a normal cytotoxic activity. We postulate a functional defect of the mononuclear phagocyte system in histiocytosis X.
