Impact of daily wearing of fabric gloves on the management of hand eczema: A pilot study in health-care workers

Longitudinal analysis of the skin microbiome in association with hand eczema, hand hygiene practices and moisturizer use

BACKGROUND

The skin microbiota maintains a physical and immunological barrier to the environment. Little is known about how the microbiome changes over time or the effect of hand hygiene practices and moisturizer use.

OBJECTIVES

To assess sex-specific changes in skin bacteria over time, and how the microbiome is related to self-reported hand eczema, hand hygiene practices and use of moisturizers.

METHODS

Swab samples from the dorsal hand were collected at baseline and 6.5 years later during the COVID-19 pandemic, in 168 participants from the RHINESSA study in Bergen, Norway. The skin samples were analysed by 16S rRNA amplicon sequencing.

RESULTS

The alpha diversity of the hand microbiome increased from baseline to follow-up, and beta diversity differed by sex at both time points. The relative abundance increased for several bacteria from baseline to follow-up, with sex-specific differences. Current hand eczema and aggravating hand eczema during the COVID-19 pandemic were associated with an increase in Staphylococcus. High hand washing frequency at home was associated with lower alpha diversity and with higher abundance of Staphylococcus, Corynebacterium, Finegoldia, and Pseudomonas and lower abundance of Propionibacterium and Pelomonas. The alpha diversity increased with increasing time passing between hand washing and sampling, whereas more frequent moisturizer use was associated with significantly lower alpha diversity, and a change in abundance for some bacteria, such as more Pseudomonas.

CONCLUSIONS

This longitudinal study revealed an overall increase in skin microbial diversity over a 6-year period, which was unexpected since follow-up was performed during the COVID-19 pandemic when vigorous hand hygienic practices were introduced. Sex-specific differences were identified at both time points. Individuals with hand eczema seem to develop a more dysbiotic skin bacterial community over time. Hand washing and use of moisturizers, with typically gender-specific habitual patterns, may lead to change in bacterial composition.

Evaluation of comfort gloves made of semipermeable and textile materials in patients with hand dermatoses: Results of a controlled multicenter intervention study (ProTection II)

BACKGROUND

Comfort gloves are used in the management of hand dermatoses.

OBJECTIVES

To compare the acceptance and tolerability of comfort gloves made of different materials in patients with hand dermatoses and their effects on skin lesions.

METHODS

In a prospective multicenter study, 284 patients with hand dermatoses were invited to wear either a cotton glove (COT) or a semipermeable Sympatex glove underneath a cotton glove (SYM/COT) for two subsequent phases of 19 consecutive nights each. A total of 88 controls were asked not to wear any comfort gloves overnight. The severity of skin lesions over time was examined. Questionnaires were used to assess health-related quality of life (HRQoL) and acceptance and tolerability of the gloves.

RESULTS

The hand dermatoses improved in all groups. No substantial intergroup differences regarding severity and HRQoL were observed. SYM/COT received better ratings regarding climate conditions and tactility while COT showed superiority in fit, wearing comfort, and practicality.

CONCLUSIONS

We confirmed that SYM/COT and COT are well tolerated and accepted suggesting that SYM/COT is a good alternative for COT as comfort gloves in patients with hand dermatoses. Individual requirements, needs, and preferences may direct the material choice.

Effects of impermeable and semipermeable glove materials on resolution of inflammation and epidermal barrier impairment after experimental skin irritation

BACKGROUND

Semipermeable membranes might be suitable for glove liners or comfort gloves in individuals with irritant contact dermatitis (ICD).

OBJECTIVES

To evaluate the effects of different glove materials on inflammation and epidermal barrier impairment after experimental skin irritation.

METHODS

Nine test areas on the volar forearms of 24 healthy volunteers were irritated with sodium lauryl sulfate (1%) and afterward covered for 6 days (6 or 8 h/day) with semipermeable Sympatex (SYM), vinyl (OCC), combinations of vinyl with Sympatex (SYM/OCC) or cotton (COT/OCC), or left uncovered (CON). Up to day 10, measurements of transepidermal water loss (TEWL), erythema (a*), skin humidity (SH) and visual scoring (VS) were applied.

RESULTS

No significant differences in skin parameters were found between COT/OCC and SYM/OCC as well as between each of the combinations and CON. SYM, COT/OCC and SYM/OCC led to better results for most skin parameters than OCC alone.

CONCLUSIONS

Occlusive material has a negative impact on skin barrier recovery and inflammation after skin irritation whereas SYM is not inferior to uncovered areas indicating good tolerability. Altogether, the data suggest that SYM is a useful alternative to COT as material for glove liners and comfort gloves in ICD patients.

Effects and acceptance of semipermeable gloves compared to cotton gloves in patients with hand dermatoses: Results of a controlled intervention study

BACKGROUND

Semipermeable gloves might be an alternative to cotton gloves in management of hand dermatoses.

OBJECTIVES

To compare acceptance and tolerability of gloves made of cotton or a semipermeable Sympatex membrane in patients with hand dermatoses and their effect on skin lesions when worn overnight.

METHODS

199 patients with work-related symmetrical hand dermatoses were asked to wear a cotton glove (COT) on one hand and a Sympatex glove underneath a cotton glove (SYM/COT) on the other hand for nineteen consecutive nights. The severity of skin lesions was regularly examined. A questionnaire on acceptance and tolerability was used in a subset of 126 patients.

RESULTS

Data on skin lesions were available for 183 participating patients (92%). The severity did not differ substantially between hands covered with SYM/COT or COT over time. Questionnaire data were available for 120 patients (95%). SYM/COT received better ratings regarding climate conditions while COT showed superiority in wearing comfort, practicality and appearance.

CONCLUSIONS

Both SYM/COT and COT were well tolerated and accepted in patients with hand dermatoses. Hence, SYM/COT may serve as suitable alternative for COT as comfort gloves supporting therapeutic efforts. The observed slight differences may influence the decision when selecting the glove type. This article is protected by copyright. All rights reserved.

Skin Microbiome in Patients with Hand Eczema and Healthy Controls: A Three-week Prospective Study

The pathogenesis of chronic hand eczema remains unclear. Insights into the skin microbiome in hand eczema and its potential relevance to disease severity may help to elucidate the underlying mechanisms of hand eczema. The aim of this study was to characterize the microbiome in patients with hand eczema and healthy controls. A 5-visit prospective study was conducted over a period of 3 weeks. At each visit, bacterial swabs were taken from the hands of patients with hand eczema and controls. The microbiome was examined using DNA extraction and 16S rRNA amplicon sequencing (V3–V4 regions). Fifty patients with hand eczema and 50 controls were included (follow-up rate=100%). The baseline bacterial α-diversity was reduced on the hands of patients with hand eczema compared with controls (effect size=–0.31; 95% confidence interval (95% CI) –0.50; –0.11; p = 0.003). The dysbiosis on the patients’ hands was stable over the study period, was associated with disease severity, and was characterized by reduced bacterial diversity and different bacterial community compositions.
