Natural rubber latex allergy in a health-care population in Wales
1Department of Dermatology, University Hospital of Wales, Box 100, Heath Park, Cardiff CF14 4XW, UK.
Background:
Type 1 natural rubber latex (NRL) allergy prevalence rates quoted vary due to the different populations studied and methodologies used for assessment and investigation of NRL allergy.
Objectives:
To investigate the rate of type 1 allergy to NRL in health-care workers (HCWs) in a single NHS trust in Wales.
Methods:
A response rate of 3716 of 5548 (67%) of the employees was obtained with a latex allergy questionnaire administered by the occupational health departments. Type 1 NRL allergy was diagnosed by correlating clinical symptoms, skin prick testing and IgE RAST to latex in the dermatology department.
Results:
The period prevalence (1998-2001) for type 1 clinical latex allergy in HCWs was 25 of 4439 (0.56%). Of the 25 positive HCWs, 18 (72%) were nurses.
Conclusions:
The low prevalence rate of type 1 NRL allergy should not lead to underestimating the importance of clinically significant NRL allergy and the risks that need to be minimized.
