Postal questionnaire study of disability associated with latex allergy among health care workers in Finland.

In this study, the association between natural rubber latex (NRL) sensitization and work ability index (WAI) among health care workers was investigated. Furthermore, the diagnostic sensitivity and specificity of a postal questionnaire as a screening device of NRL allergy was evaluated. The study population consisted of 32 female health care workers with an occupational latex allergy, and 51 control subjects who were individually matched for age and occupation. A self-administered two-part questionnaire, including seven items of a work ability index (WAI), as well as questions on glove-related symptoms, was mailed to the subjects. The median age for NRL allergic subjects was 40 years (range 23-62), and the diagnosis of occupational latex allergy had been made six years (range 2-16) before the present study. The WAI scores were on average lower among the sensitized subjects as compared with their nonsensitized controls. Even after removing the contribution of the presence of allergic eczema, diagnosed by a physician, from the original WAI score, the proportion of NRL allergic subjects and the control subjects in the good work ability category were 34% and 53%, respectively. Ten health care workers (31%) had changed occupation and one early retirement had occurred after sensitization to NRL. The sensitivity and specificity of the present self-administered questionnaire as an indicator for latex allergy was 84% and 98%, respectively. In conclusion, there is a clear association between NRL allergy and a decrease in the WAI among health care workers, which cannot be explained by age, gender, profession, or history of atopy.

Glove-related rhinopathy among hospital personnel.

Hypersensitivity to natural rubber latex (NRL) in health care personnel exposed to powdered latex gloves appears as conjunctivitis, rhinitis, nasal congestion, cough, dyspnea, or bronchial asthma in approximately 30% of all cases with latex allergy while most of the patients have contact urticaria. The purpose of the present study was to determine the prevalence of latex-induced allergic rhinitis in health care workers using NRL gloves on a daily basis. Clinical examination accompanied by skin prick test (SPT) with latex glove extracts and common aeroallergens, measurements of specific IgE to NRL, and lung function tests were performed in 25 symptomatic workers and 11 latex-exposed asymptomatic controls. Sensitization to NRL was detected using SPT in one (4%) of 25 symptomatic workers but not in any of the asymptomatic controls. Positive SPT to aeroallergens was demonstrated in 8/25 symptomatic workers and 6/11 controls. Measurements of forced vital capacity, forced expiratory volume in I sec, and bronchial methacholine challenge did not show any significant differences between the study groups. In conclusion, NRL-aeroallergen-induced occupational rhinitis may occur among physicians and nurses who have a frequent use of latex gloves on a daily basis at hospital work. However, a relatively low prevalence of NRL-induced occupational rhinitis is associated with profuse consumption of no-powder sterile gloves.

Glove-induced dermal and respiratory symptoms among health care workers in one Finnish hospital.

To evaluate the prevalence of skin and respiratory symptoms associated with the use of protective gloves in health care workers, an inquiry study was carried out on 534 hospital employees who used protective latex or vinyl gloves on a daily basis at work. The prevalence of skin disorders related to the usage of gloves was 56%. Rhinorrhea or nasal congestion was present in 13% of the workers who used powdered disposable gloves. The prevalence of both skin and respiratory symptoms was significantly higher among the workers who used gloves > 2 hours a day (p < 0.001). The skin disorders were more common in young employees. The findings indicate that most of the symptoms were caused by irritation or an immediate, IgE-mediated allergy. We conclude that there is a positive correlation between the duration of daily glove usage at work and the skin and respiratory symptoms. In order to reduce skin disorders associated with the daily use of gloves, it is necessary to develop safer materials in the glove manufacturing process.

Detection of airborne natural rubber latex by immunoelectrophoresis, RAST inhibition, and immunospot method.

Occupational dermal and respiratory allergies caused by natural rubber latex (NRL) have been encountered with increasing frequency in health care workers. In order to measure the amount of airborne NRL, area and personal air sampling was performed in three hospital laboratories where workers used latex gloves. The total dust levels in laboratory air samples were lower than 0.17 mg/m3. RAST inhibition suggested that NRL antigens may exist both in the area and personal samples. Immunospot measurements, rocket immunoelectroporesis, and rocket radioimmunoelectrophoresis did not show any NRL activities in laboratory airsamples, although they were able to detect immunoactive material in positive control filter specimens. We conclude that the airborne NRL concentration was undetectable in daily hospital laboratory environment where workers used disposable NRL gloves. Airborne NRL, however, can be measured by using immunological assays.
