ABSTRACT

Background: Rubber additives are common causes of allergic contact dermatitis (ACD) worldwide, yet data from Turkey remain

Objectives: To evaluate the prevalence of rubber additive sensitisation and its clinical/occupational relevance in a tertiary re ferral centre.

Methods: A retrospective study on 2687 consecutively patch-tested patients with rubber additives at our allergy unit between 1996 and 2023.

Results: Rubber sensitisation was found in 10.6%, with a slight increase after 2010. Male predominance was noted (female: male=1:2.3). Thiurams and carbamates were the most frequent sensitizers. ACD was diagnosed in 7.9%, primarily caused by gloves (85.5%). Hands were most commonly affected (94.4%). Logistic regression analysis showed that thiuram and carba mate sensitisation was significantly associated with hand eczema, while benzothiazole derivatives were linked to foot eczema. Airborne ACD occurred in 4.2%, mainly in healthcare workers. Hand eczema with and without wrist extension was observed with similar frequency. Occupational ACD accounted for 79.3% of cases, especially among construction (56.8%) and healthcare workers (14.8%), with a relative increase in the latter group after 2015.

Conclusions: The high prevalence of sensitisation from rubber gloves is concerning. Legal measures are urgently needed, includ ing safer additives and clearer glove labelling. Patch testing remains essential, even without the classic glove-pattern distribution.

Summary

The present guideline summarizes all aspects of patch testing for the diagnosis of contact allergy in patients suspected of suffering, or having been suffering, from allergic contact dermatitis or other delayed-type hypersensitivity skin and mucosal conditions. Sections with brief descriptions and discussions of different pertinent topics are followed by a highlighted short practical recommendation. Topics comprise, after an introduction with important definitions, materials, technique, modifications of epicutaneous testing, indi vidual factors influencing the patch test outcome or necessitating special considerations, children, patients with occupational contact dermatitis and drug eruptions as special groups, patch testing of materials brought in by the patient, adverse effects of patch testing, and the final evaluation and patient counselling based on this judgement. Finally, short reference is made to aspects of (continuing) medical education and to electronic collection of data for epidemiological surveillance.

Key words: contact allergy; guideline; patch testing; review.

ABSTRACT

Introduction:

The human skin acts as a pro‑ tective barrier against external pathogens and hosts a diverse microbiome consisting of bacte‑ ria, fungi, viruses, and archaea. Disruptions to the skin microbiome can impact immune func‑ tion, leading to inflammatory and autoimmune conditions. The importance of pH for the micro‑ biome is paramount. Cosmetic skincare prod‑ ucts interact with the skin microbiome and skin pH, playing a key role in maintaining microbial balance. Research suggests that products with non-physiological pH levels may disrupt the skin microbiota. Our clinical study aimed to evaluate the effects of low-pH cosmetic products (pH<5) on the skin microbiome, contributing to improved skin health.

Methods: The clinical study focused on evalu‑

ating the skin microbiome diversity following

the application for 28 days of four different low

pH cosmetic products (vitamin C, resveratrol, a

collagen mask, and a native algae mask) on the

forearms of post-menopausal women with skin

pH>5.5.

Results:

The diversity of the natural skin microbiome increased consistently through‑ out the study, evident in both the untreated area and after the application of the Vitamin C Concentrate, Resveratrol Concentrate, Colla‑ gen Mask, and Native Algae Mask, as indicated by Shannon’s diversity index. The native algae mask notably reduced the Corynebacterium genus and significantly lowered the pH. The skin pH changes corresponded with microbiota stability.

Conclusions:

In conclusion, enhanced diver‑ sity of the natural skin microbiome was observed over the study duration. None of the investi‑ gational products caused significant disruption to the skin microbiome diversity, as evidenced by the stable Shannon’s diversity index and relative abundance of specific genera. Notably, the native algae mask significantly decreased the presence of the opportunistic pathogenic Corynebacterium genus, which is likely attribut‑ able to a minor reduction in skin pH following extended product use. The findings suggest that the use of low-pH skincare products, like the native algae mask, do not disrupt skin micro‑ biome diversity and may have the potential to positively impact skin microbiome diversity and health by reducing certain pathogenic microbial

Key Summary Points

Why carry out this study?

This study investigated the intricate relation‑ ship between cosmetic skincare products, the skin microbiome, and skin health. It evaluated the impact of low-pH skincare products on skin microbiome diversity and skin barrier function.

What was learned from this study?

The diversity of the skin microbiome increased following the application of vita‑ min C concentrate, resveratrol concentrate, a collagen mask, and a native algae mask, as demonstrated by Shannon’s diversity index. The native algae mask notably decreased the genus Corynebacterium and lowered the pH, with the pH changes aligning with micro‑ biota stability. Low-pH skincare products maintain skin microbiome diversity and health by reducing pathogenic microbial populations, promot‑ ing a positive impact on skin microbiome health.
