Latex hypersensitivity in Department of Veterans Affairs health care workers: glove use, symptoms, and sensitization

Characterization of Cleaning and Disinfection Product Use, Glove Use, and Skin Disorders by Healthcare Occupations in a Midwestern Healthcare Facility

Healthcare facility staff use a wide variety of cleaning and disinfecting products during their daily operations, many of which are associated with respiratory or skin irritation or sensitization with repeated exposure. The objective of this study was to characterize the prevalence of cleaning and disinfection product use, glove use during cleaning and disinfection, and skin/allergy symptoms by occupation and identify the factors influencing glove use among the healthcare facility staff. A questionnaire was administered to the current employees at a midwestern Veterans Affairs healthcare facility that elicited information on cleaning and disinfection product use, glove use during cleaning and disinfection, skin/allergy symptoms, and other demographic characteristics, which were summarized by occupation. The central supply/environmental service workers (2% of the total survey population), nurses (26%,), nurse assistants (3%), and laboratory technicians (5%) had the highest prevalence of using cleaning or disinfecting products, specifically quaternary ammonium compounds, bleach, and alcohol. Glove use while using products was common in both patient care and non-patient care occupations. The factors associated with glove use included using bleach or quaternary ammonium compounds and using cleaning products 2-3 or 4-5 days per week. A high frequency of glove use (≥75%) was reported by workers in most occupations when using quaternary ammonium compounds or bleach. The use of alcohol, bleach, and quaternary ammonium compounds was associated with skin disorders (p < 0.05). These research findings indicate that although the workers from most occupations report a high frequency of glove use when using cleaning and disinfection products, there is room for improvement, especially among administrative, maintenance, and nursing workers. These groups may represent populations which could benefit from the implementation of workplace interventions and further training regarding the use of personal protective equipment and the potential health hazards of exposure to cleaning and disinfecting chemicals.

Conversion to Low-Protein, Powder-Free Surgical Gloves: Is it Worth the Cost?

This study was conducted to determine changes in overall costs associated with conversion to powder-free gloves including cost of workers' compensation cases for natural rubber latex (NRL)-related symptoms and health care workers' glove satisfaction. The study, a 2–year, longitudinal design with retrospective and prospective aspects, was developed to determine health care worker use of powder-free, low-protein NRL gloves, sensitization, cost, and glove satisfaction. Informed consent was obtained from 103 health care workers. Prior to glove conversion, nearly one-half (44%, 36 of 82) of the operating room staff reported symptoms related to NRL exposure. At the end of the 14–month data collection period, only 27% (22 of 82, McNemar test = .007) reported symptoms related to NRL exposure. Additionally, a cost savings of $10,000 per year for gloves was evident with reports of increased user satisfaction. This study demonstrated that conversion to the use of powder-free, low-protein NRL gloves not only reduces health care worker NRL symptoms, but also positively affects the costs of glove purchases and workers' compensation.

Current asthma and asthma-like symptoms among workers at a Veterans Administration Medical Center

INTRODUCTION

Healthcare workers are at increased risk for respiratory disorders. The purpose of our respiratory health survey was to estimate the prevalence of current asthma and asthma-like symptoms and their association with workplace exposures and tasks among healthcare workers at a Veterans Administration (VA) Medical Center.

MATERIAL AND METHODS

Information on respiratory health and work characteristics, including tasks performed, products used, and exposures, were collected by questionnaire from a convenience sample of workers employed at the VA Medical Center during 2012-2014. Associations of asthma and asthma-like symptoms with cleaning and disinfecting tasks and products as well as exposure to dampness and molds, and construction dust were evaluated using log-binomial regression.

RESULTS

The prevalence of current asthma was 17.6% and almost half of all workers reported asthma-like symptoms. We observed elevated prevalence of current asthma among the VA healthcare workers compared to the U.S. general and working adult populations. Asthma and asthma-like symptoms were significantly associated with mold, dampness, and construction material exposures; cleaning and disinfecting products; and cleaning or disinfecting tasks.

CONCLUSIONS

Workplace exposures and tasks associated with current asthma and asthma-like symptoms were identified but further research is needed to investigate the temporal association between workplace exposures and current asthma and asthma-like symptoms.

Latex gloves allergy in dental workers, Iran

Dermal-respiratory reactions to latex glove is a common problem and sometimes life threatening. Some of the health related past histories such as hand dermatitis, atopy and food allergy increase the probability of these reaction. The purpose of this study was to evaluate reactions to latex gloves amongst dental workers in military dental health centers. In this cross-sectional descriptive survey, dental workers with minimum three months length of employment and most often use of latex gloves were asked to fill standard questionnaire regarding latex related clinical manifestation and personal medical history and predisposing factors. Those with clinical problems did Skin Prick Test (SPT). In this study 330 personnel were assessed. The mean age and length of employment was 31.6 and 8 years, respectively. The most occupation was dentistry. A total of 232 subjects (70.3%) reported latex gloves-allergic symptoms. 72 (21.8%) of persons have history of atopy and food allergy was seen in 114 (34.5%). 63 (19.1%) of subjects reported history of hand dermatitis. All of these had positive regression with allergic responses. Among 73 (34%) symptom positives, 28 (38%) had positive result of SPT. In this survey, the prevalence of allergic reactions is higher than similar studies, which may be due to type of gloves, lack of preemployment assessments and other factors. Because of relationship between allergic reactions to latex gloves and some medical histories, it seems to be necessary for preemployment evaluation and periodic health surveillance of dental workers.

Skin differences, needs, and disorders across global populations

Accurately determining the incidence and prevalence of dermatologic disease in most large populations has been challenging for reasons ranging from the lack of easily quantifiable tests and measures to imprecision around definitions of race, ethnicity, photo skin type, pigmentation, and population groups. Compounding the problems with these categorizations is the fact that skin disease and skin health are affected not just by inherent risk factors but also by habits and environment. Thus, a fundamental question remains as we evaluate the effects of cultural and environmental factors: do genetic factors account for most of the difference that we see in skin types? Is the primary influence the way the skin mediates the environmental insult of UV radiation or how inflammation is handled? Is melanization the primary characteristic that we should measure and consider? This article will provide an introduction to current knowledge and future directions researchers are taking in differentiating both the biological differences of skin and the clinical manifestations of skin disease among the groups described above. This discussion will be followed by a brief overview of cultural practices and environmental factors that are known to have significant impact on skin disease and a summary of the most common conditions that are encountered worldwide.

Latex allergen IgE assays in the assessment of Veterans Affairs health care workers

BACKGROUND

A previous multicenter study of Veterans Affairs health care workers evaluated hospital participants for latex hypersensitivity. Well-defined groups from that study allowed us to explore the diagnostic utility of newer antilatex allergen IgE immunoassays in the present study.

OBJECTIVES

To determine whether an enhanced CAP (ENHCAP) assay or an enzyme-linked immunosorbent assay (ELISA) identifies latex glove symptomatic individuals with antilatex allergen IgE that had not been detected by the CAP assay used in the original study and to determine the specificity of the ENHCAP assay.

METHODS

The ELISA measured IgE antibody to Malaysian nonammoniated natural rubber latex extract (MNA), Hev b1, Hev b5, and Hev b6. Four patient groups were tested: confirmed latex glove allergic, latex glove symptomatic, latex glove sensitized/asymptomatic, and latex glove nonallergic.

RESULTS

The ENHCAP assay and the MNA ELISA were highly concordant with the original CAP assay. In the subgroup with latex glove symptoms that were previously negative by the CAP assay, the ENHCAP assay value was elevated in 7 (11%) of 64 samples, only 3 of which were class 2 or higher. The MNA ELISA result was positive in only 4 (6%) of these 64 samples, and 3 of these were fractionally above the cutoff value for this assay.

CONCLUSIONS

The ENHCAP assay and the MNA ELISA identified a few additional positive individuals in the group that was latex glove symptomatic and originally CAP assay negative. The ENHCAP assay and the MNA ELISA produced only a modest improvement in diagnostic sensitivity over that of the original CAP assay.

Pseudo-Latex Allergy Associated With ???Latex??? Paint Exposure: A Potential Cause of Iatrogenic Disability

OBJECTIVE

We sought to describe outcomes for three health care workers with natural rubber latex (NRL) allergy reporting illness after exposure to latex paint.

METHODS

We undertook a retrospective review of medical and occupational histories, diagnostic, treatment, and work recommendations. Outcomes included lost time, workers compensation indemnity costs, and return to work.

RESULTS

None of the paints contained NRL. Cases 1 and 2 initially were misdiagnosed as suffering allergic reactions to NRL, resulting in 7 and 23 months lost time, $15,790 and $139,000 indemnity costs, respectively, and both failing to return to work. Case 3 was correctly diagnosed as not exposed to NRL, with only several lost days, no indemnity costs, and continued to work.

CONCLUSIONS

The failure to recognize that synthetic paints do not contain NRL can lead to misdiagnosis, inappropriate exposure, and work avoidance recommendations and iatrogenic disability.

Latex allergy and skin

PURPOSE OF REVIEW

In this review we address the prevalence and outcome of latex allergy in health care workers (HCWs). Recent findings in natural rubber latex (NRL) allergens and trials of specific immunotherapy (SIT) are also of interest.

RECENT FINDINGS

A study involving skin prick test (SPT) screening in HCWs in Russia and adjacent countries found a prevalence of latex allergy of 1.9%. Questionnaire studies performed in Wales and in the USA identified prevalence rates of about 0.6%. An intervention undertaken at the Mayo Clinic, in which only gloves with low or undetectable allergen levels were allowed, reduced markedly the incidence of NRL allergy. Two studies, one from Finland and another from Ohio, showed that outcomes in latex-allergic HCWs are generally good. A study involving SPT screening showed that 6% of construction workers had latex allergy. A questionnaire study among allergists practicing in the USA showed that 62% performed latex SPT and 6% reported anaphylaxis, which mostly occurred while using a homemade SPT solution. Hev b 2, Hev b 5, Hev b 6.01 and Hev b 13 produced positive SPT reactions in over 60% of latex-allergic individuals. Topical application of NRL in a murine model of protein contact dermatitis caused a striking increase in prohevein-specific (Hev b 6.01) immunoglobulin E levels, together with a T-helper-2 type dermatitis. A placebo-controlled SIT trial with NRL extract alleviated cutaneous symptoms but caused some systemic reactions in latex-allergic patients.

SUMMARY

Low prevalence rates suggest that the peak of the latex allergy epidemic has already passed in HCWs. Hospital-wide interventions requiring use of low-allergen gloves reduce sensitization and changing gloves to nonlatex ones, or even using low-allergen latex gloves, in the affected individuals appears to confer adequate secondary prevention. In the USA there is an urgent need for standardized latex SPT reagent. Hev b 5 and Hev b 6.01 are major in vivo NRL allergens. Findings in mice suggest that NRL proteins eluting from latex gloves may also cause hand eczema in humans. SIT with NRL extract must still be considered an experimental treatment.
