Response: ​The human microbiome seems to play an important role in health and disease, by influencing host cells and contributing to host immunity. A balanced interplay between host cells and resident bacteria is important, and dysbiosis is linked to several diseases, including skin diseases like atopic dermatitis. Patients with atopic dermatitis suffer from ​frequent skin infections, and their skin microbiome is dominated by S. aureus. Frequent skin infections lead to frequent use of antibiotics, and with worldwide increase in resistant bacteria, a better understanding of the interplay between host and bacteria is paramount in order to develop new treatment strategies.

MedicalResearch.com Interview with: Dr Jill Stocks PhD, Research Fellow Centre for Occupational and Environmental Health, Centre for Epidemiology; NIHR Greater Manchester Primary Care Patient Safety Translational Research Centre, Centre for Primary Care Institute of Population Health, University of Manchester, UK. Medical Research: What is the background for this study? What are the main findings? Dr. Stocks: Reducing healthcare-associated infections has been a priority in the UK over recent decades; and this has been reflected in interventions and guidelines focussing on improving hygiene procedures. During 2004 to 2008 the Cleanyourhands campaign promoted hand hygiene in all NHS trusts. There was anecdotal evidence from dermatologists and occupational physicians that irritant contact dermatitis was on the increase in healthcare workers, and that it was caused by hand hygiene. We investigated whether or not there was an increase in the incidence of irritant contact dermatitis in healthcare workers due to hand hygiene or other types of hygiene coinciding with the interventions and guidelines promoting hygiene. We used reports made by dermatologists to the Occupational and Health reporting network, a voluntary surveillance scheme collecting reports of work-related ill-health. Trends in incidence of irritant contact dermatitis due to hygiene in healthcare workers were compared with trends in control groups (irritant contact dermatitis in workers with other jobs) using a quasi-experimental (interrupted time series) design. We found a 4.5 fold increase in irritant contact dermatitis due to hand hygiene and hygiene in general in healthcare workers between 1996 and 2012. The results also suggested a steepening of the increase in incidence during the rollout period of the Cleanyourhands campaign but the limitations of the data made this less clear cut.
