Risk factors for latex sensitization among health care workers

Health care workers, children with spina bifida and rubber industry workers show higher prevalence of latex sensitization compared to the general popu lation, and they are considered at-risk groups. Our aim was to establish th e prevalence of latex allergy among health care workers at the Clinica Univ ersitaria of Navarra and to analyze potential risk factors, including perso nal and family history of atopy, sex, as well as factors leading to enhance d exposure to latex such as being a nurse, belonging to surgical department s, having undergone previous surgery and the number of gloves employed per week. Health care workers (n = 1, 150) (doctors, nurses, assistant nurses, laboratory technicians and practicing medical and nursing students) were ev aluated using a questionnaire and skin prick test (SPT). Serum specific IgE was determined by CAP-FEIA (Pharmacia, Sweden) in those with positive SPT: The participation index was 26.17%: 301 volunteers answered the questionna ire and underwent SPT: Fifteen subjects presented positive SPT to latex it was found that 5% of the health care workers from the Clinica Universitaria were sensitized to latex allergens. Thirteen were females and two males. M ean age was 38.4 (+/-7.09) years. Nine were nurses, three assistant nurses, one nursing student and two medical doctors. Eight belonged to medical, fi ve to surgical and two to laboratory departments. There were no significant differences among the subjects in the prevalence of latex sensitization. F ourteen reported symptoms related to latex, mostly pruritus, dryness and/or redness of the hands (n = 12) and rhinitis (n = 6). Only one subject repor ted no symptoms when using latex products. Eight were atopic; personal hist ory of atopy was the only significant (odds ratio = 5.10, p <0.01) risk fac tor for latex sensitization. It was concluded that atopic health care worke rs show a more increased risk of latex sensitization than those who are non atopic.
