Abstract:

Two latex antigens, one extracted from surgical gloves (GE) and the other from the sap of Hevea brasiliensis plant (RPE) were characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and two-dimensional gel electrophoresis. These antigens were used to detect latex specific IgE and IgG antibodies by enzyme-linked immunosorbent assay (ELISA) in the sera of patients with meningomyelocele (spina bifida) and of normal controls. Of the 36 patients studied, 26 had wheal-and-flare skin-prick test reactivity to latex antigen with 11/26 having had a history of anaphylaxis to latex products. Twenty three of the 26 sera from skin-test positive patients and 10/11 patients with history of anaphylaxis demonstrated significant levels of latex specific IgE and IgG in the sera, whereas only 1/14 normals showed significant antibodies to latex. The remaining 10 patients, all skin-test negative with latex antigens, showed only low levels of antibodies. The findings indicate that the ELISA used in the present study employing partially characterized antigens has sensitivity and specificity to detect latex specific antibodies in the sera of suspected patients and can be used for presumptive diagnosis of latex allergy.
