Contact Allergens in Medical Devices: A Cause for Concern?
In spite of the medical benefit of professional medical products, there is a opportunity for these items to trigger adverse skin reactions in some sufferers. Results from a European retrospective study, published in the European Journal of Allergy and Scientific Immunology, display that approximately just one quarter of clients with suspected allergic call dermatitis were referred for patch screening for get hold of allergic reactions related with clinical gadgets, highlighting the possibility of a significant prevalence of get in touch with allergens in these gadgets.
“We uncovered it essential to publish these results, because up until finally now no clear figures have been documented concerning this certain scientific issue,” explained analyze writer Olivier Aerts, MD, a researcher in the make contact with allergy unit at the College Clinic Antwerp, Antwerp, Belgium, in an interview with Medscape Health care Information.
For the review, Aerts and colleagues done a retrospective evaluation of healthcare product end users with suspected allergic contact dermatitis. All patients experienced been patch tested at a tertiary European clinic among 2018 and 2020.

The cohort bundled clients who professional suspected get hold of allergy from medical adhesives (n = 57), gloves (n = 38), topical and surface clinical equipment (n = 38), glucose sensors and insulin pumps (n=74), and prostheses (n = 75). Other health care merchandise involved with speak to allergy in a further 44 sufferers integrated surgical glues, face masks, compression stockings, condoms, and suture supplies.
Over-all, 326 sufferers had been patch-tested for the duration of the 30-month examine time period. Roughly 25.8% of all people — such as 299 older people and 27 children — were being referred for call allergy involved with health-related gadgets.
Acrylates had been the most often encountered speak to allergens and ended up observed in diabetic issues units and healthcare adhesives. Likely pores and skin sensitizers incorporated colophonium-connected substances, D-limonene, isothiazolinone derivatives, salicylates, and sulphites, all of which have been determined across most goods.
In accordance to the investigators, lots of of the labels for the professional medical products created no mention of the possible pores and skin sensitizers, apart from in the scenarios of some topical and surface disinfectants. And a lot of topical items are usually promoted as professional medical gadgets somewhat than cosmetics, additional complicating labeling challenges, in accordance to Aerts.
“What ought to be accomplished to enable any affected person suffering from allergic contact thanks to professional medical devices is that these gadgets ought to be labeled with all their parts, or at the really minimum with the opportunity skin sensitizers these may possibly contain,” Aerts explained. He included that manufacturers should “set up much more cooperation with doctors/dermatologists who appraise these types of clients,” a cooperation that often exists with cosmetic providers.
Aerts noted that when it really is important for patch testers and dermatologists to be knowledgeable of the prevalence of allergic get hold of dermatitis in health care machine end users, firms producing these equipment need to also be aware of these potential issues. “On top of that, legislators/regulators ought to maybe concentrate some extra on the cutaneous aspect effects these items might provoke,” he claimed, “as this awareness may well hopefully also provide as a stimulant to perform far more clinical allergy exploration in this discipline.”
Leonard Bielory, MD, an allergist at Robert Wooden Johnson University Medical center in Rahway, New Jersey, told Medscape Health-related Information that the conclusions are “alarming” and should really heighten clinicians’ recognition of the chance of allergic get hold of dermatitis amid medical unit end users.
Bielory, who was not involved in the investigation, famous that the conclusions from this examine could not be totally generalizable to the US, presented the study was executed in Europe. “In contrast to other international locations, the US is pretty conscientious about allergic responses to objects becoming used in hospitals,” he added, “or these kinds of that the issue listed here is that several of these items would be an adverse reaction, which you have to report.” He advised that additional analysis in this subject is wanted to identify the prevalence of feasible skin sensitizers in products exclusively formulated and marketed in the US.
The review experienced no precise funding. Aerts and Bielory have disclosed no appropriate financial relationships.
