title: [Natural history of occupational allergy to latex in health care workers].
abstract: The analysis of natural history of allergy to natural rubber latex (NRL) in health care workers, including the influence of exposure cessation on the clinical status and objective allergy markers was the objective of the study. The study covered 58 patients with recognised allergy to NRL. Of this number, 26 were followed up for 2 years after diagnosing NRL allergy. Medical examination, skin prick tests for common allergens and NRL, determination of total serum IgE and NRL-specific IgE antibodies, rest spirometry and non-specific bronchial hyperactivity test with histamine were performed. The retrospective analysis of clinical manifestation of NRL allergy revealed in 36% of patients progression of symptoms from local urticaria and rhinitis to systemic reactions. Two years after the cessation of exposure to NRL, symptoms became less severe in the majority of patients and even a clearance of allergic symptoms was observed, as well as the decrease in doses of inhalative glicocorticosteroids was noted. This was accompanied by the decline in non-specific bronchial hyperactivity. Although the skin prick tests showed the tendency to remain positive, the decrease in the level of specific anti-NRL IgE was found in 10 patients (including the RAST negativisation in one case). In conclusion, clinical progress from NRL-induced contact urticaria and allergic rhinitis to systemic reactions was observed only in part of patients with NRL allergy, which cannot be taken as a rule. Significant reduction of clinical symptoms or even total remission of NRL-allergic symptoms could be observed after exposure cessation.
