The immune profile of contact allergy patients

Nonspecific parameters of antibody-related and cellular immune responses were studied in a group of 30 patients treated for manifest contact allergy to metals (chromium, cobalt, nickel) or non-metals (epoxy resin, rubber) confirmed in each of them by specific patch test positivity. In addition, every patient was tested for the pattern of skin reactivity to the Immunoskintest (USOL, Prague) antigens administered intradermally. The group of 20 metal allergy patients had decreased suppressor index values, enhanced formation of immediate active rosettes and an elevation of serum IgM and IgA immunoglobulins. The remaining 10 patients reacted by a reduced ability of neutrophils to exert phagocytic action on HEMA particles and a decrease in levels of alpha-2-macroglobulins in serum. This may help select a series of suitable immune parameters to be used as prediction tests in the secondary prevention of cases of occupational contact dermatitis.
