The epidemiology of hand eczema in the general population - prevalence and main findings

Hand strength and dexterity in individuals with hand eczema

BACKGROUND

Patients with hand eczema often describe symptoms such as pain, clumsiness and difficulty flexing their fingers, thus impairing the function of the hand.

OBJECTIVE

The aim of this study was to investigate whether hand eczema is associated with a measurable impairment of hand strength and dexterity. We also studied the relationship between hand function and the ability to perform activities of daily living (ADL), pain level and quality of life measured with the Dermatology Life Quality Index (DLQI).

METHODS

Twenty-one participants with ongoing hand eczema were examined with well-established methods for measuring hand grip strength, pinch strength and dexterity. A questionnaire was designed to investigate perceived ability to perform ADL. The participants were also asked to grade their current pain level, and the DLQI was used to assess the participants' quality of life. A group of 12 participants was reinvestigated when healed.

RESULTS

The participants demonstrated a significant improvement in all functional tests when healed. There was a strong correlation between ADL and both dexterity and hand grip strength. There was also a strong correlation between ADL and pain. All participants reported some difficulty performing ADL.

CONCLUSIONS

Our results suggest that ongoing hand eczema may lead to a measurable decrease of strength and dexterity of the hand, leading to an impairment of the ability to perform ADL and consequently to a poorer quality of life.

The Efficacy of Colloidal Oatmeal Cream 1% as Add-on Therapy in the Management of Chronic Irritant Hand Eczema: A Double-Blind Study

BACKGROUND

Irritant contact dermatitis (ICD) is the most frequent cause of hand eczema (HE). There is promising evidence with the use of topical oatmeal compounds in the management of inflammation- and itch-responses associated with diverse dermatologic conditions. This study aimed to evaluate the clinical benefit of colloidal oatmeal cream in the management of chronic irritant HE.

METHODS

From October 2018 to November 2019, 79 patients with diagnosis of chronic irritant HE were allocated into either intervention or control groups by block randomization method. Besides fluocinolone 0.025% ointment for the first 2 weeks of treatment period, patients in the intervention and control groups were asked to use colloidal oatmeal 1% cream or base cream for additional 4 weeks as monotherapy. Changes in the HE severity based on the hand eczema severity index (HESCI) score, pruritus severity based on the visual analogue scale (VAS), and impact of skin disorder on patients quality of life based on the Dermatology Life Quality Index (DLQI) from baseline to weeks 2, 4, and 6 were assessed in the study groups.

RESULTS

Fifty subjects, 26 in intervention and 24 in control, completed the course of the study. The results indicated, though relatively comparable decrease in mean HESI and VAS scores was observed in both groups by the end of week 2, thereafter until end of the study a non-return of symptoms to baseline conditions was observed in the intervention group, while there was a significant return of symptoms to baseline conditions in the control group (p value<0.001 in both conditions). Further, a noticeable improvement in the DLQI score was seen in the intervention group compared with the control group (p value<0.001).

CONCLUSION

Findings demonstrate that colloidal oatmeal, a natural product with proven barrier protection, moisturization, anti-inflammatory, and soothing properties, can have ameliorative effects on eczema severity symptoms in patients with chronic irritant HE.

Expression of retinoid receptors in hand eczema

BACKGROUND

Hand eczema is the most common occupational skin disease. The etiology is multifactorial. Systemic alitretinoin, a pan-retinoic receptor agonist, has proven efficacy in the treatment of recalcitrant chronic hand eczema; however, its precise mechanism of action in hand eczema is not fully understood.

AIMS

Assessment of the level of expression of retinoid receptors (RAR and RXR) in the skin of patients with hand eczema in an attempt to explain their possible role in the pathogenesis of the disease.

METHODS

Thirty patients with hand eczema and 30 age- and sex-matched healthy controls were included. Full clinical examination was done, and tissue levels of retinoic acid receptor (RAR) and retinoid x receptor (RXR) were measured by quantitative real-time PCR (qRT-PCR).

RESULTS

The levels of RAR and RXR expression were significantly downregulated in the patient group compared to the control group; (P < 0.001) for both. In addition, there was a statistically significant negative correlation between Osnabrück Hand Eczema Severity Index (OHSI) and the levels of RAR and RXR expression (P < 0.001).

CONCLUSION

Deficient retinoid receptor expression has a primary role in the pathogenesis, clinical phenotype, and severity of hand eczema and sheds light on the mechanism of action of retinoids in the treatment of chronic hand eczema.

Hand eczema among Dutch beekeepers - a cross-sectional study

BACKGROUND AND OBJECTIVES

Studies of beekeepers have mostly focused on contact allergy to propolis. The overall prevalence of hand eczema (HE) in beekeepers has not been studied. Our objectives were to gain insight into the prevalence of HE in the Dutch beekeeper population; to define the impact of beekeeping activities on HE and vice versa; and to determine associated factors.

PATIENTS AND METHODS

We used a cross-sectional online survey. Dutch beekeepers answered questions on beekeeping activities, the prevalence and characteristics of HE, including severity, and the impact of the disease on beekeeping.

RESULTS

We analyzed 833 surveys (12 % of Dutch beekeepers). The one-year prevalence of HE was 13.2 %, and the lifetime prevalence was 20.5 %. In 28 patch-tested beekeepers with hand eczema, eight (28.6 %) were allergic to propolis. Atopic dermatitis was the only variable associated with HE: the odds ratio was 4.53 (95 % confidence interval 2.78-7.38). One in three beekeepers reported that HE was caused or worsened by beekeeping, although only 3.8 % reported working less at beekeeping because of HE, and the impact of HE on beekeeping activities (as perceived by beekeepers) is low.

CONCLUSIONS

In this sample of Dutch beekeepers, hand eczema was more prevalent than in the general population, but seems to have had little impact on the beekeeping activities of the majority of beekeepers.

Development of a Conceptual Model of Chronic Hand Eczema (CHE) Based on Qualitative Interviews with Patients and Expert Dermatologists

INTRODUCTION

Chronic hand eczema (CHE) is a relapsing inflammatory dermatologic disease. Signs and symptoms can have a significant impact on patients' health-related quality of life (HRQoL). The aim of this study is to characterize the core signs, symptoms and impacts of CHE to develop a conceptual model.

METHODS

A structured literature search and qualitative interviews with 20 adult CHE patients in the US and 5 expert dermatologists were conducted to explore the patient experience of CHE signs, symptoms and impacts. Findings were used to support the development of a conceptual model.

RESULTS

There was a paucity of CHE qualitative research in the literature, supporting the need for the prospective qualitative research. The primary signs and symptoms identified from the literature review and interviews included itch, dryness, cracking, pain, thickened skin and bleeding. The most salient impacts included embarrassment and appearance concerns, frustration, impacts on work and sleep disturbance. Saturation was achieved for all signs, symptoms and impact concepts.

CONCLUSIONS

Findings from this literature review and in-depth qualitative interviews supported the development of a comprehensive conceptual model documenting the signs, symptoms and impacts relevant to CHE patients. Such a model is of considerable value given the lack of existing studies in the literature focused on the qualitative exploration of the CHE patient experience. Limitations included the patient sample being only from the US and not including some CHE subtypes.

Efficacy and Safety of Alitretinoin Therapy in Korean Elderly Patients with Chronic Hand Eczema: A Retrospective Single Center Study

Background

Chronic hand eczema (CHE) tends to be refractory to conventional therapy. Previous clinical trials have found that alitretinoin is an effective and well-tolerated treatment for CHE. However, there is a relative lack of data on the effectiveness of alitretinoin in elderly patients.

Objective

The aim of this study was to investigate the efficacy and safety of oral alitretinoin in elderly patients with moderate to severe CHE in Korea.

Methods

We retrospectively investigated 46 CHE patients who were treated with either 10 mg or 30 mg of alitretinoin between June of 2016 and July of 2018. The physician's global assessment (PGA) was used to evaluate treatment efficacy. All adverse events were retrospectively evaluated with respect to laboratory testing, including complete blood cell count, fasting blood chemistry, lipid profile, and liver and thyroid function tests.

Results

The mean patient age in this study was 71.0±5.1 years. The treatment period was over eight weeks. A total of 38 of 46 patients (82.6%) exhibited clinical improvement with PGA ratings of ‘clear’ or ‘almost clear.’ There were 13 patients (28.3%) who experienced an adverse effect, with the most common being headache (13.0%) and gastrointestinal symptoms (8.7%) followed by xerosis (6.5%). A total of 13 patients developed or exhibited worsening hypertriglyceridemia (28.3%).

Conclusion

Alitretinoin can be considered a safe and effective treatment option in elderly patients with moderate to severe CHE.

[Prevention of hand eczema]

Apart from endogenous factors, hand eczema is often caused by irritant or allergic contact dermatitis related to occupational or non-occupational exposure to skin hazards. This enables several complementary approaches on the level of primary, secondary and tertiary prevention. A high priority is set on identification and subsequent reduction or elimination of causative exposures. Important preventive approaches include legal regulations, technical and organizational measures as well as correct use of adequate personal protective equipment (e.g. protective gloves). Interventions based on health education are conducted to improve individual protective behaviour. Even though evidence-based proof of effectiveness is limited, preventive measures are considered of particular importance for avoidance of occupational hand eczema and its adverse sequelae. Therefore, a complex, step-wise approach to occupational skin diseases has been established in Germany. In recent years, the positive impact of secondary and tertiary preventive measures of this approach has been demonstrated.

Positive change in hand care habits using therapeutic patient education in chronic hand eczema

BACKGROUND

Chronic hand eczema (CHE) is a major burden for patients. Maintenance treatment involves prevention measures limiting detrimental behaviour and aggravating factors.

OBJECTIVE

To evaluate the effect of a standardised care program including therapeutic patient education (TPE) on hand care behaviours, clinical severity, quality of life, and work productivity.

METHODS

A single-centre study was conducted prospectively. Together with the prescription of a topical steroid, patients participated in individual TPE sessions. Evaluations were performed initially and repeated three months after the therapeutic intervention. They included a structured analysis of hand care behaviours, the assessment of the mTLSS (modified Total Lesion Symptom Score), DLQI (Dermatology Life Quality Index), and WPAI (Work Productivity and Activity Impairment).

RESULTS

Seventy-one patients were included (30 men, 42.3%). Three months after completion of the standardised care program, hand care behaviours such as hand washing and rinsing, hand drying, wearing protective gloves, using moisturizing creams, and following specific treatments and recommendations for CHE improved significantly in the 58 patients who completed the study and were associated with a significant improvement in the mTLSS, DLQI, and WPAI scores.

CONCLUSIONS

TPE helps patients change their hand care behaviours and adopt skin protection measures, and may improve CHE severity, quality of life, and work productivity.

A behaviour change package to prevent hand dermatitis in nurses working in health care: the SCIN cluster RCT

BACKGROUND

Although strategies have been developed to minimise the risk of occupational hand dermatitis in nurses, their clinical effectiveness and cost-effectiveness remain unclear.

OBJECTIVES

The Skin Care Intervention in Nurses trial tested the hypothesis that a behaviour change package intervention, coupled with provision of hand moisturisers, could reduce the point prevalence of hand dermatitis when compared with standard care among nurses working in the NHS. The secondary aim was to assess the impact of the intervention on participants' beliefs and behaviour regarding hand care, and the cost-effectiveness of the intervention in comparison with normal care.

DESIGN

Cluster randomised controlled trial.

SETTING

Thirty-five NHS hospital trusts/health boards/universities.

PARTICIPANTS

First-year student nurses with a history of atopic tendency, and full-time intensive care unit nurses.

INTERVENTION

Sites were randomly allocated to be 'intervention plus' or 'intervention light'. Participants at 'intervention plus' sites received access to a bespoke online behaviour change package intervention, coupled with personal supplies of moisturising cream (student nurses) and optimal availability of moisturising cream (intensive care unit nurses). Nurses at 'intervention light' sites received usual care, including a dermatitis prevention leaflet.

MAIN OUTCOME MEASURE

The difference between intervention plus and intervention light sites in the change of point prevalence of visible hand dermatitis was measured from images taken at baseline and at follow-up.

RANDOMISATION

Fourteen sites were randomised to the intervention plus arm, and 21 sites were randomised to the intervention light arm.

BLINDING

The participants, trial statistician, methodologist and the dermatologists interpreting the hand photographs were blinded to intervention assignment.

NUMBERS ANALYSED

An intention-to-treat analysis was conducted on data from 845 student nurses and 1111 intensive care unit nurses.

RESULTS

The intention-to-treat analysis showed no evidence that the risk of developing dermatitis was greater in the intervention light group than in the intervention plus group (student nurses: odds ratio 1.25, 95% confidence interval 0.59 to 2.69; intensive care unit nurses: odds ratio 1.41, 95% confidence interval 0.81 to 2.44). Both groups had high levels of baseline beliefs about the benefits of using hand moisturisers before, during and after work. The frequency of use of hand moisturisers before, during and after shifts was significantly higher in the intensive care unit nurses in the intervention plus arm at follow-up than in the comparator group nurses. For student nurses, the intervention plus group mean costs were £2 lower than those for the comparator and 0.00002 more quality-adjusted life-years were gained. For intensive care unit nurses, costs were £4 higher and 0.0016 fewer quality-adjusted life-years were gained.

HARMS

No adverse events were reported.

LIMITATIONS

Only 44.5% of participants in the intervention plus arm accessed the behaviour change package.

CONCLUSION

The intervention did not result in a statistically significant decrease in the prevalence of hand dermatitis in the intervention plus group.

FUTURE WORK

Participants had a high level of baseline beliefs about the importance of using hand moisturisers before, during and after work. Future research should focus on how workplace culture can be changed in order for that knowledge to be actioned.

The color of skin: red diseases of the skin, nails, and mucosa

Red color is pervasive in local and systemic skin conditions. It is a color that often reflects variations of dermal blood flow and extends beyond the rubor and calor of inflammation. The pathophysiology of red skin involves remote and local chemical mediators that dilate arteriolar smooth muscle and increase blood flow to superficial vessels and capillary beds. Incident light hits hemoglobin, which preferentially absorbs light of shorter wavelengths, such as blue, and reflects warmer colors. Due to its pervasiveness and consistency, red color is a useful descriptive factor in helping narrow a differential diagnosis. Red skin disorders include a variety of conditions involving endocrine mediators, cardiovascular responses, and the disruption of the skin barrier. An understanding of the blood's role in these disorders equips clinicians to generate differential diagnoses through the lens of pathophysiology. Dermatologists can improve management by considering red skin as part of systemic disease rather than as an isolated incident.

[Hand eczema registries: Background, value and future prospects : Registry data in hand eczema research]

BACKGROUND

Population-based studies on hand eczema (HE) show a 1-year prevalence up to 10.0% of which 5-7% are severe chronic HE (CHE) which can severely impair the life of those affected. Registry data can help to investigate and optimize burden of disease as well as healthcare of HE in a real-life setting.

OBJECTIVES

To assess how data from registries have been used in studies concerning HE. What is the benefit of registry data and which limitations occur when researchers use registry data in their studies?

MATERIALS AND METHODS

This is a review of publications where registry data were used in studies concerning HE. Most of the publications included in this review are from Germany, but some studies are from other countries like Denmark and Switzerland.

RESULTS

Currently, only Germany and Switzerland have established a disease-specific registry for CHE. The chronic hand eczema registry with the acronym CARPE assesses the characteristics of CHE as well as treatment and course of the diseases in a real-life setting. In Denmark, data from public registries (Danish National Board of Industrial Injuries Registry) were used to identify patients with occupational HE in order interview them using a questionnaire. In Saarland and north Bavaria, registries for occupational skin diseases were established in the 1990s, and more than 90% of the patients registered in these had HE.

CONCLUSION

Diseases registries for HE can generate considerable data to describe characteristics of HE patients in a dermatological setting as well as the treatments prescribed. The completeness of data can be assessed in disease registries, while this is not possible when using public registry data.

Factors influencing prognosis for occupational hand eczema: new trends

BACKGROUND

Variables traditionally reported to influence the prognosis of occupational hand eczema (OHE) are atopic dermatitis (AD) and contact sensitization. However, recent studies indicate that lifestyle factors may be of major importance.

OBJECTIVES

To identify factors influencing the prognosis in a cohort of patients with recognized OHE.

METHODS

In this register-based cohort study, individuals with hand eczema recognized as occupational disease in the period January 2010-December 2011 were identified using files from Labor Market Insurance Denmark and included in the study. At baseline, information on sex, age, occupation, wet work, AD and contact sensitization was collected. In 2015 participants received a questionnaire with questions about lifestyle factors, current occupation and healing of OHE.

RESULTS

In total, 2703 patients received the questionnaire; 1491 responded to the question about healing of OHE and were included in the study. Altogether, 19·3% of patients reported complete healing at follow-up. Current tobacco smoking and a high level of stress were factors inversely associated with healing of hand eczema (P < 0·001 and P = 0·030, respectively), while a high level of exercise was significantly related to healing of eczema (P = 0·011). Change of profession was a favourable prognostic factor, while age, sex, AD, contact sensitization and education did not significantly influence prognosis.

CONCLUSIONS

Traditionally important risk factors such as AD and contact sensitization had no marked influence on prognosis, while lifestyle factors were of major importance. Our findings indicate that risk factors may vary over time, allowing for new perspectives on prevention. What's already known about this topic? Occupational hand eczema has a relapsing course and a poor overall prognosis. Atopic dermatitis and contact sensitization have previously been reported as risk factors for a poor prognosis. What does this study add? The results indicate that lifestyle factors are of importance for the prognosis of occupational hand eczema. Traditionally reported risk factors such as atopic dermatitis and contact sensitization do not currently influence prognosis.

Interventions for hand eczema

BACKGROUND

Hand eczema is an inflammation of the skin of the hands that tends to run a chronic, relapsing course. This common condition is often associated with itch, social stigma, and impairment in employment. Many different interventions of unknown effectiveness are used to treat hand eczema.

OBJECTIVES

To assess the effects of topical and systemic interventions for hand eczema in adults and children.

SEARCH METHODS

We searched the following up to April 2018: Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, AMED, LILACS, GREAT, and four trials registries. We checked the reference lists of included studies for further references to relevant trials.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared interventions for hand eczema, regardless of hand eczema type and other affected sites, versus no treatment, placebo, vehicle, or active treatments.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Primary outcomes were participant- and investigator-rated good/excellent control of symptoms, and adverse events.

MAIN RESULTS

We included 60 RCTs, conducted in secondary care (5469 participants with mild to severe chronic hand eczema). Most participants were over 18 years old. The duration of treatment was short, generally up to four months. Only 24 studies included a follow-up period. Clinical heterogeneity in treatments and outcome measures was evident. Few studies performed head-to-head comparisons of different interventions. Risk of bias varied considerably, with only five studies at low risk in all domains. Twenty-two studies were industry-funded.Eighteen trials studied topical corticosteroids or calcineurin inhibitors; 10 studies, phototherapy; three studies, systemic immunosuppressives; and five studies, oral retinoids. Most studies compared an active intervention against no treatment, variants of the same medication, or placebo (or vehicle). Below, we present results from the main comparisons.Corticosteroid creams/ointments: when assessed 15 days after the start of treatment, clobetasol propionate 0.05% foam probably improves participant-rated control of symptoms compared to vehicle (risk ratio (RR) 2.32, 95% confidence interval (CI) 1.38 to 3.91; number needed to treat for an additional beneficial outcome (NNTB) 3, 95% CI 2 to 8; 1 study, 125 participants); the effect of clobetasol compared to vehicle for investigator-rated improvement is less clear (RR 1.43, 95% CI 0.86 to 2.40). More participants had at least one adverse event with clobetasol (11/62 versus 5/63; RR 2.24, 95% CI 0.82 to 6.06), including application site burning/pruritus. This evidence was rated as moderate certainty.When assessed 36 weeks after the start of treatment, mometasone furoate cream used thrice weekly may slightly improve investigator-rated symptom control compared to twice weekly (RR 1.23, 95% CI 0.94 to 1.61; 1 study, 72 participants) after remission is reached. Participant-rated symptoms were not measured. Some mild atrophy was reported in both groups (RR 1.76, 95% CI 0.45 to 6.83; 5/35 versus 3/37). This evidence was rated as low certainty.Irradiation with ultraviolet (UV) light: local combination ultraviolet light therapy (PUVA) may lead to improvement in investigator-rated symptom control when compared to local narrow-band UVB after 12 weeks of treatment (RR 0.50, 95% CI 0.22 to 1.16; 1 study, 60 participants). However, the 95% CI indicates that PUVA might make little or no difference. Participant-rated symptoms were not measured. Adverse events (mainly erythema) were reported by 9/30 participants in the narrow-band UVB group versus none in the PUVA group. This evidence was rated as moderate certainty.Topical calcineurin inhibitors: tacrolimus 0.1% over two weeks probably improves investigator-rated symptom control measured after three weeks compared to vehicle (14/14 tacrolimus versus 0/14 vehicle; 1 study). Participant-rated symptoms were not measured. Four of 14 people in the tacrolimus group versus zero in the vehicle group had well-tolerated application site burning/itching.A within-participant study in 16 participants compared 0.1% tacrolimus to 0.1% mometasone furoate but did not measure investigator- or participant-rated symptoms. Both treatments were well tolerated when assessed at two weeks during four weeks of treatment.Evidence from these studies was rated as moderate certainty.Oral interventions: oral cyclosporin 3 mg/kg/d probably slightly improves investigator-rated (RR 1.88, 95% CI 0.88 to 3.99; 1 study, 34 participants) or participant-rated (RR 1.25, 95% CI 0.69 to 2.27) control of symptoms compared to topical betamethasone dipropionate 0.05% after six weeks of treatment. The risk of adverse events such as dizziness was similar between groups (up to 36 weeks; RR 1.22, 95% CI 0.80 to 1.86, n = 55; 15/27 betamethasone versus 19/28 cyclosporin). The evidence was rated as moderate certainty.Alitretinoin 10 mg improves investigator-rated symptom control compared with placebo (RR 1.58, 95% CI 1.20 to 2.07; NNTB 11, 95% CI 6.3 to 26.5; 2 studies, n = 781) and alitretinoin 30 mg also improves this outcome compared with placebo (RR 2.75, 95% CI 2.20 to 3.43; NNTB 4, 95% CI 3 to 5; 2 studies, n = 1210). Similar results were found for participant-rated symptom control: alitretinoin 10 mg RR 1.73 (95% CI 1.25 to 2.40) and 30 mg RR 2.75 (95% CI 2.18 to 3.48). Evidence was rated as high certainty. The number of adverse events (including headache) probably did not differ between alitretinoin 10 mg and placebo (RR 1.01, 95% CI 0.66 to 1.55; 1 study, n = 158; moderate-certainty evidence), but the risk of headache increased with alitretinoin 30 mg (RR 3.43, 95% CI 2.45 to 4.81; 2 studies, n = 1210; high-certainty evidence). Outcomes were assessed between 48 and 72 weeks.

AUTHORS' CONCLUSIONS

Most findings were from single studies with low precision, so they should be interpreted with caution. Topical corticosteroids and UV phototherapy were two of the major standard treatments, but evidence is insufficient to support one specific treatment over another. The effect of topical calcineurin inhibitors is not certain. Alitretinoin is more effective than placebo in controlling symptoms, but advantages over other treatments need evaluating.Well-designed and well-reported, long-term (more than three months), head-to-head studies comparing different treatments are needed. Consensus is required regarding the definition of hand eczema and its subtypes, and a standard severity scale should be established.The main limitation was heterogeneity between studies. Small sample size impacted our ability to detect differences between treatments.

Using Patch Testing to Improve Therapeutic Outcome in the Treatment of Hand Eczema in Vietnamese Patients

BACKGROUND:

Hand eczema is a common chronic and relapsing skin disease with various clinical features. Hand eczema aetiology can be allergic contact dermatitis (ACD), irritant contact dermatitis (ICD), atopic dermatitis (AD) and unknown or combination causes. If the causative agents are not detected treatment of hand eczema will be a failure. A patch test can be useful to detect causative agents in suspected allergic contact hand eczema. Then patients will avoid contacting them. This results in the improvement of hand eczema. In Vietnam, patch test has not been used before, so we conduct this study.

AIM:

To identify causative allergens by using patch test with 28 standard allergens in consecutive patients.

METHODS:

A group of 300 HE patients from the National Hospital of Dermatology and Venereology (NHDV) in Vietnam were enrolled in this study. They were divided into 4 groups-ACD, ICD, AD and unknown aetiology. The patient was patch tested with 28 standard allergens to identify the causative agents.

RESULTS:

Among the 300 HE enrolled patients, ACD accounted for 72.7%, AD and ICD had the same rate of 12.7%. 39.3% of the patients had a positive patch test. Reaction to nickel sulfate was the most common (10.3%), followed by potassium dichromate (9.7%), cobalt (4%) and fragrance mix (3.1%). About one-third of the cases had relevant clinical reactions correlated with the contact agents and clinical history. Males reacted to cement, thiuram mix and formaldehyde more than females, while females reacted to a nickel more than males.

CONCLUSIONS:

Hand eczema has variable clinical features and diverse aetiology. ACD is an important cause of hand eczema that can be managed with a patch test to detect causative allergens. Nearly 40% of HE cases had positive patch test. Relevant patch test reactions were seen in one-third of the patients. We propose using patch test detect causative agents in suspected allergic contact hand eczema. Then patients will avoid contacting them. This results in the improvement of hand eczema.

Vesicular hand dermatitis

Vesicular hand dermatitis is a type of eczema involving the fingers, hands, and sometimes the feet. It is common in primary care, requiring prompt treatment to prevent chronicity. The cause is often unknown, making the condition challenging to treat. Management consists of avoiding irritants and using emollients and topical corticosteroids.

Quality of Life in Hand Eczema Questionnaire: Validation of the Japanese version of a disease-specific measure of quality of life for hand eczema patients

Hand eczema (HE) is a common skin disease that impairs health-related quality of life (HRQOL). Impairments in HRQOL have already been reported in Japanese HE patients using the Skindex-16. Recently, an instrument to measure disease-specific HRQOL in HE patients was developed by an international expert group, consisting of domains for: (i) symptoms; (ii) emotions; (iii) functioning; and (iv) treatment and prevention. The objective of this study is to translate the English-language version of the Quality of Life Hand Eczema Questionnaire (QOLHEQ) to Japanese and then to validate the Japanese version. The Japanese version of the QOLHEQ, the Dermatological Life Quality Index (DLQI) and a questionnaire regarding basic demographic information, including patient ratings of HE severity, were distributed to Japanese HE patients. Additionally, a dermatologist evaluated patients' HE severity using the Physician Global Assessment. A total of 124 patients with a mean age of 43.7 years were included in the analysis, and 78% of the sample was female. Cronbach's alphas for the domains symptoms, emotions, functioning, and treatment and prevention were 0.76, 0.89, 0.88 and 0.81, respectively. The total QOLHEQ score showed a strong correlation with the DLQI, a moderate correlation with patient-rated severity and weak correlations with dermatologist-rated severity and the number of consultations. The Japanese version of the QOLHEQ showed excellent reliability and high validity. The Japanese version of the QOLHEQ is ready for use in epidemiological studies to evaluate HRQOL impairments in HE patients.

A novel dermo-cosmetic product containing thermal spring water, sucralfate, copper sulfate, and zinc sulfate in the management of hand eczema

Background

The regular use of cosmetic products plays a role in the management of hand eczema (HE) and aids in improving barrier function reducing dryness, roughness, pruritus and improving quality of life (QoL). The aim of this open-label study was to assess the efficacy and the reparative effect of a dermo-cosmetic product on subjects suffering from HE after 7 and 21 days of daily application.

Methods

The product was a water-in-oil (W/O) emulsion containing the active ingredients Avène thermal spring water, sucralfate, and copper and zinc sulfates. In total, 32 subjects suffering from either contact dermatitis or climatic dermatitis participated in the trial. The modified total lesion symptom score and physician global assessment scores were used to describe the severity of HE. The safety of the product was assessed through clinical scoring. The subjective tolerance, and acceptance, were documented using a self-assessment questionnaire completed by the subjects. The impact of the dermatosis on QoL was evaluated using the Dermatology Life Quality Index.

Results

After 7 days of application, both the physician and subjects noticed a significant improvement in HE. The formula was very well tolerated and accepted. These benefits were correlated with a significant improvement in QoL.

Conclusion

The W/O emulsion used in this study demonstrated real benefits for the subjects suffering from contact dermatitis and climatic dermatitis.

Study protocol: efficacy of oral alitretinoin versus oral cyclosporine A in patients with severe recurrent vesicular hand eczema (ALICsA): a randomised prospective open-label trial with blinded outcome assessment

INTRODUCTION

Systemic treatment with alitretinoin is registered for all clinical types of severe chronic hand eczema. However, it is especially effective in the hyperkeratotic subtype and less effective in non-hyperkeratotic forms. Cyclosporine A (cyclosporine) is prescribed for hand eczema in daily practice as well. It has shown to be particularly effective in patients with vesicular hand eczema. The primary objective of this study is to compare efficacy of alitretinoin and cyclosporine in the treatment of severe recurrent vesicular hand eczema.

METHODS AND ANALYSIS

This is an investigator-initiated randomised prospective open-label trial with blinded outcome assessment. Severity assessments and laboratory measurements will be conducted corresponding to daily practice. The study population will consist of 72 adult patients (age 18-75 years) with severe recurrent vesicular hand eczema. Patients are treated with either (group I) alitretinoin 30 mg once daily or (group II) cyclosporine with a starting dose of 5 mg/kg/day and a decrease in dosage after 8 weeks to 3-3.5 mg/kg/day. The treatment period is 24 weeks for both drugs. Primary endpoint for efficacy is response to treatment, defined as an improvement of ≥2 steps on a Physician Global Assessment, using a validated Photoguide, after 24 weeks of treatment. Secondary endpoints are improvement of Hand Eczema Severity Index, Quality of Life in Hand Eczema Questionnaire and a Patient Global Assessment. Adverse events and time to response will be registered. Furthermore, cost-utility, quality-adjusted life years and cost-effectiveness will be assessed with the EQ-5D-5L questionnaire while monitoring costs.

Presenteeism in a Dutch hand eczema population-a cross-sectional survey

BACKGROUND

Presenteeism (attending work despite complaints and ill health, which should prompt rest and absence) has been overlooked in the field of hand eczema.

OBJECTIVES

To examine the 1-year prevalence of presenteeism related to hand eczema in a population of hand eczema patients who visited a tertiary referral centre. Secondary objectives: to identify intrinsic/extrinsic reasons for presenteeism and to evaluate associated factors.

METHODS

This was a cross-sectional questionnaire study. Presenteeism was defined as "going to work despite feeling you should have taken sick leave because of hand eczema". Respondents answered questions about socio-demographic factors, clinical features, occupational characteristics, and hand eczema related to occupational exposure.

RESULTS

Forty-one per cent (141/346) of patients who had both worked and had hand eczema during the past 12 months reported presenteeism. The most often reported reasons were: "Because I do not want to give in to my impairment/weakness" (46%) and "Because I enjoy my work" (40%). Presenteeism was associated with: mean hand eczema severity; absenteeism because of hand eczema; improvement of hand eczema when away from work; and high-risk occupations.

CONCLUSIONS

In this study, presenteeism was common and predominantly observed in patients with more severe hand eczema and occupational exposure. The most frequently reported reasons for presenteeism were of an intrinsic nature.

Investigating the therapeutic potential of a probiotic in a clinical population with chronic hand dermatitis

BACKGROUND

Hand dermatitis or hand eczema (HD) is one of the most common dermatologic conditions. Lesions, scaling, pruritus and pain are chronic and relapsing. Improved HD has been reported with the probiotic composed of Lactobacillus acidophilus CL1285, Lactobacillus casei LBC80R and Lactobacillus rhamnosus CLR2 (Bio-K+).

PURPOSE

Investigation of the therapeutic potential of this probiotic as the sole systemic treatment for adults with nonacute HD.

SUBJECTS AND METHODS

A single-center study documented clinical ratings and patient-reported outcomes in adults with chronic HD. The probiotic was taken orally for 12 weeks, adjunctive to standard topical treatments and preventative measures.

RESULTS

Most of the 30 subjects with mild to severe HD were compliant with the probiotic. Around 22 of the 30 subjects were able to complete the study, and of these subjects, an improvement was noted in 19. One required systemic therapy, and one subject was not able to tolerate the probiotic and therefore discontinued the study. 23% of the subjects achieved clear or almost clear hands by the end of 12 weeks. Pruritus, which was a common complaint at baseline, was improved with 59% of symptomatic patients within 2 weeks.

CONCLUSION

It is feasible and safe to administer Bio-K+ for HD. Clinicians saw an improvement in most subjects' hands, and cases of significant improvement in dermatitis were documented. Pruritus was the most rapidly relieved symptom, as reported by patients.

Hand eczema as a risk factor for food allergy among occupational kitchen workers

BACKGROUND

An increasing number of studies in children is highlighting the importance of transdermal routes of exposure to food allergens through damaged skin in the pathogenesis of food allergies. However, data on this in adults are limited. A few case-series studies has documented development of food allergy among kitchen workers with hand eczema after direct contact exposure to foods.

METHODS

To explore the significance of hand eczema as a risk factor for food allergies in adults at the epidemiological level, we performed a cross-sectional web-based questionnaire survey on kitchen workers whose exposures were classed as occupational (cooks and food handlers, n = 1592) or non-occupational (housewives, n = 1915). Logistic regression was used to explore the association between the presence/severity of hand eczema and the risk of food allergy after adjustment for potential confounders.

RESULTS

Current hand eczema and current diagnosed food allergy were more common among occupational kitchen workers (OKW) than among non-occupational kitchen workers (NOKW) (32.3%-vs-29.9% and 9.9%-vs-3.8%, respectively). Current hand eczema was significantly associated with increased risk of current diagnosed food allergy in OKW (adjusted odds ratio 2.4, 95% CI 1.6-3.7). Those with more severe hand eczema were more likely to suffer from allergic symptoms for foods, and diagnosed food allergy.

CONCLUSIONS

This study illustrates a significant public health problem in the adult population, documenting a major impact of hand eczema on the ongoing adult food allergy epidemic.

An observer-blinded randomized controlled pilot trial comparing localized immersion psoralen-ultraviolet A with localized narrowband ultraviolet B for the treatment of palmar hand eczema

BACKGROUND

Hand eczema is a common inflammatory dermatosis that causes significant patient morbidity. Previous studies comparing psoralen-ultraviolet A (PUVA) with narrowband ultraviolet B (NB-UVB) have been small, nonrandomized and retrospective.

OBJECTIVES

To conduct an observer-blinded randomized controlled pilot study using validated scoring criteria to compare immersion PUVA with NB-UVB for the treatment of chronic hand eczema unresponsive to topical steroids.

METHODS

Sixty patients with hand eczema unresponsive to clobetasol propionate 0·05% were randomized to receive either immersion PUVA or NB-UVB twice weekly for 12 weeks with assessments at intervals of 4 weeks. The primary outcome measure was the proportion of patients achieving 'clear' or 'almost clear' Physician's Global Assessment (PGA) response at 12 weeks. Secondary outcome measures included assessment of the modified Total Lesion and Symptom Score (mTLSS) and the Dermatology Life Quality index (DLQI).

RESULTS

In both treatment arms, 23 patients completed the 12-week assessment for the primary outcome measure. In the PUVA group, five patients achieved 'clear' and eight 'almost clear' [intention-to-treat (ITT) response rate 43%]. In the NB-UVB group, two achieved 'clear' and five 'almost clear' (ITT response rate 23%). For the secondary outcomes, median mTLSS scores were similar between groups at baseline (PUVA 9·5, NB-UVB 9) and at 12 weeks (PUVA 3, NB-UVB 4). Changes in DLQI were similar, with improvements in both groups.

CONCLUSIONS

In this randomized pilot trial recruitment was challenging. After randomization, there were acceptable levels of compliance and safety in each treatment schedule, but lower levels of retention. Using validated scoring systems - PGA, mTLSS and DLQI - as measures of treatment response, the trial demonstrated that both PUVA and NB-UVB reduced the severity of chronic palmar hand eczema.
