Work-related asthma from cleaning agents versus other agents.

Area of Science:

• Occupational Health
• Pulmonology
• Environmental Health

Background:

• Epidemiologic studies frequently link cleaning agents to work-related asthma (WRA).
• Clinical data on WRA caused by cleaning products remain limited.
• This study investigates clinical features of WRA associated with cleaning product exposure.

Purpose of the Study:

• To compare socio-demographic and clinical characteristics of WRA patients exposed to cleaning products versus non-cleaning products.
• To identify common cleaning agents implicated in WRA.
• To analyze patient demographics and clinical outcomes in a tertiary care setting.

Main Methods:

• Analysis of a database of 208 probable WRA patients referred to a Canadian tertiary care asthma center (2000-2014).
• Utilized Chi-squared and independent samples t-tests for categorical and continuous data analysis.
• Compared WRA cases attributed to cleaning agents against those with other exposures.

Main Results:

• 11% of WRA cases (22 patients) were linked to cleaning product exposure, including occupational asthma (OA) and work-exacerbated asthma (WEA).
• Cleaning agent-exposed WRA patients showed a higher proportion of females (82% vs 35%), healthcare workers (41% vs 4%), and workers' compensation claims (86% vs 64%).
• Surfactants, alcohols, disinfectants, and acids were the most frequent cleaning agent exposures; specific agents were often unidentified due to multiple exposures.

Conclusions:

• Patients with WRA from cleaning agent exposure in a tertiary clinic share similar clinical characteristics with those from other causes.
• Key exposures include surfactants, alcohols, disinfectants, and acids.
• WRA from cleaning products presents distinct demographic patterns, notably higher prevalence in females and healthcare workers.
