[Follow-up of symptoms, parameters of respiratory function, and data on specific sensitization in a group of subjects with latex-induced asthma and rhinitis].
We re-investigated 13 workers 6 years (SD 2) after the first diagnosis of asthma or rhinitis caused by latex, to update the exposure to latex, the eventual symptoms, respiratory function (spirometry and metacholine PD20 FEV1), skin prick test to common allergens and latex, RAST to latex, total IgE levels and eosinophils count in the blood. At the follow up, all the workers stopped wearing powdered latex gloves, but for 10 an indirect exposure to latex was still possible. All cases referred improvement of respiratory symptoms at work, but 7 workers occasionally complained of mild symptoms. No statistically significant variations of respiratory function test and of the immunological parameters were found. The workers with persistent respiratory symptoms at work had a longer duration of symptoms before the diagnosis (p = 0.02), if compared with workers without symptoms.
