An unusual case of hyper-production of IgE, treated by plasmapheresis.
A 15-year-old boy with severe inflammatory skin lesions from an early age was found to have extremely elevated serum IgE levels (up to 376.000 IU/ml). His skin showed positive direct immunofluorescence for IgE and he had peripheral and bone marrow eosinophilia. No evidence for atopic disease was found, but he suffered intestinal helminthic infection of moderate intensity. He showed a somewhat depressed cell mediated immune response but a normal polymorphonuclear function. Various treatments that included anti-inflammatory, anti-allergic, anti-parasitic, anti-mycotic and PUVA therapy did not significantly improve his condition A therapeutic test using plasmapheresis produced marked, though short-lived clinical improvement. We believe that this case might result from the superimposition of the stimulatory effects of intestinal helminthiasis on a background of intrinsic hyper-production of IgE.
