Asthma related to cleaning agents: a clinical insight

 Cleaning workers are exposed to many substances ans irritants.Today post is from bmj.org.

In recent years, there has been a growing concern about the potential role of exposure to cleaning products in the initiation and aggravation of asthma. 

Epidemiological surveys have consistently documented increased prevalence3–5 and incidence6–8 rates of asthma in workers exposed to cleaning materials and/or disinfectants, especially in domestic cleaners3,4 and healthcare workers.

 In addition, some studies have reported an increased risk of work-related asthma symptoms in exposed workers.

However, there is still limited knowledge on the specific exposures and pathophysiological mechanisms involved in cleaning-related asthma.

Cleaning materials typically contain a wide variety of ingredients, some of which are respiratory irritants, such as chlorine-releasing agents and ammonia, while others are potential airway sensitizers.
 Asthma in cleaners has been mostly associated with the irritant effects of cleaning products, which may exacerbate asthma and, at high exposure levels, cause acute irritant-induced asthma (or ‘reactive airways dysfunction syndrome’)

Nevertheless, occasional case reports have ascribed occupational asthma (OA) due to specific airway hypersensitivty to components of detergents or disinfectants.2 Overall the determinants of cleaning-related asthma symptoms remain largely uncertain since most...
