EADV Task Force Pruritus White Paper on chronic pruritus and chronic prurigo: Current challenges and future solutions

Chronic pruritus (CP) is frequent in general medicine and the most common complaint in general dermatology. The prevalence of CP is expected to rise in the future due to the ageing population. The clinical presentation, underlying aetiology and treatment strategy of CP are heterogeneous. Also, individual treatment aims and physical, psychic and economic burdens of patients might vary. Chronic prurigo (CPG) is the most severe disease in the chronic pruritus spectrum, being associated with long-standing scratch-induced skin lesions and a therapy refractory itch-scratch-cycle. It is thus important to raise disease awareness for CP and CPG in the general public and among decision-makers in the health system. Further, there is a need to support a rational clinical framework to optimize both diagnostics and therapeutics. Currently, there is still a shortcoming regarding approved therapies and understanding CP/CPG as severe medical conditions. Therefore, the EADV Task Force Pruritus decided to publish this white paper based on several consensus meetings. The group consented on the following goals: (a) ensure that CP is recognized as a serious condition, (b) increase public awareness and understanding of CP and CPG as chronic and burdensome diseases that can greatly affect a person's quality of life, (c) clarify that in most cases CP and CPG are non-communicable and not caused by a psychiatric disease, (d) improve the support and treatment given to patients with CP to help them manage their disease and (e) publicize existing therapies including current guidelines. We aim to point to necessary improvements in access and quality of care directed to decision-makers in health policy, among payers and administrations as well as in practical care.

Dermatological patients with itch report more stress, stigmatization experience, anxiety and depression compared to patients without itch: Results from a European multi-centre study

BACKGROUND

Itch as the most common symptom in dermatology has been shown to be related to psychological factors such as stress, anxiety and depression. Moreover, associations were found between perceived stigmatization and itch. However, studies investigating the differences between patients with dermatoses with and without itch regarding perceived stress, stigmatization, anxiety and depression are missing. Therefore, one of the aims of the second study of the European Society for Dermatology and Psychiatry (ESDaP study II) was to investigate these relationships in a large cohort of patients with different itchy dermatoses.

RESULTS

3399 patients with 14 different itchy dermatoses were recruited at 22 centres in 17 European countries. They filled in questionnaires to assess perceived stigmatization, stress, signs of clinically relevant anxiety or depression, itch-related quality of life, the overall health status, itch duration, frequency and intensity. The most significant association between the severity of itching and the perception of stress was observed among individuals with rosacea (correlation coefficient r = 0.314). Similarly, the strongest links between itch intensity and experiences of stigmatization, anxiety, and depression were found in patients with seborrheic dermatitis (correlation coefficients r = 0.317, r = 0.356, and r = 0.400, respectively). Utilizing a stepwise linear regression analysis, it was determined that within the entire patient cohort, 9.3% of the variation in itch intensity could be accounted for by factors including gender, levels of anxiety, depression, and perceived stigmatization. Females and individuals with elevated anxiety, depression, and perceived stigmatization scores reported more pronounced itch intensities compared to those with contrary attributes.

CONCLUSION

This study underscores the connection between experiencing itch and its intensity and the psychological strain it places on individuals. Consequently, psychological interventions should encompass both addressing the itch itself and the interconnected psychological factors. In specific cases, it becomes imperative for dermatologists to direct individuals towards suitable healthcare resources to undergo further psychological assessment.

[Stigmatization and social anxiety in patients with skin diseases]

Stigmatization of patients with skin diseases has only recently attracted more attention in research. However, both external stigmatization by society and self-stigmatization by the affected patients are widespread in patients with skin diseases. Many studies show that in this group of patients, the experience of both kinds of stigmatization is associated with psychosocial burden, such as social anxiety. This is often independent of the visibility of skin lesions. The psychosocial burden of affected individuals may lead to psychological comorbidities, such as depression or anxiety disorders, making it important to screen patients in dermatologic settings for the presence of these conditions. Interventions to reduce external and self-stigmatization have been developed, but more randomized controlled trials are needed to test the effects of such interventions.

Associations of self-reported skin symptoms with age, sex, and living with a partner: Findings from a representative survey in view of the biomedical and the biopsychosocial model

Introduction

Social and demographic characteristics are crucial determinants of health. The objective of this contribution is to study the associations of skin symptoms and sociodemographic variables in the general population, and to discuss these findings in view of the biomedical and the biopsychosocial models of skin diseases.

Methods

A national face-to-face household survey with a representative sample of the German general population assessed 19 self-reported skin symptoms (N = 2,487). Associations with age, sex, and living situation (alone vs. with partner) were analyzed using logistic regression analyses.

Results

The frequencies of pimples and biting of the nails decreased by approximately 30% per age decade, and oily skin, the feeling of disfigurement, excoriations, and sun damages decreased by 8%-15% per age decade. Dryness of the skin increased by 7% per decade. Sensitive skin and dryness were approx. twice as likely in females as in males. Dryness of the skin, itch, and excoriations were 23%-32% more frequent in participants living without a partner.

Discussion

The biomedical model explains some of the findings well (e.g., reduction of pimples with age). The interpretation of other results is facilitated by the biopsychosocial model (e.g., association of living without a partner and itch). This suggests a stronger integration of psychological and social factors into the understanding and treatment of symptoms of the skin.

Interest in a short psychological intervention in patients with psoriasis: a cross-sectional observational study at a German clinic

Introduction

Utilization of health services is not only associated with the kind of illness one has, but also with patient characteristics like age, sex or psychological variables. Psoriasis (PS) is a chronic inflammatory skin condition, in which psychological interventions were shown to be beneficial regarding not only psychological variables, but also regarding the skin status. The present study investigated with regard to which patient characteristics PS-patients with interest in participation in a short psychological intervention differ from PS-patients without interest.

Methods

This cross-sectional questionnaire study was conducted at a German rehabilitation clinic. At the beginning of their stay at the clinic, 127 PS-patients filled in questionnaires to assess the severity of their PS, stress, illness perceptions, mindfulness, anxiety, and depression. Interest in taking part in a short psychological intervention was assessed using a dichotomous item. The statistical analysis comprised group comparisons using t-tests of patients with and without interest to take part in a short psychological intervention.

Results

Sixty-four of the participants were male (50.4%). Participants were 50.7 ± 10 years on average (range: 25-65). 50.4% of them had a mild, 37.0% a moderate, and 12.6% a severe PS. Results indicated that patients with interest in a short psychological intervention were younger, reported to have more skin symptoms due to their PS (higher skin-related illness identity), were more anxious and depressed, but less stressed and less mindful than patients without interest.

Conclusion

This study shows that in PS-patients with certain characteristics, it might help to raise awareness on the relationship between psychological factors and symptoms of the skin disease in order to motivate this group of patients to take part in psychological interventions to improve their skin condition. Further studies are needed to investigate whether patients who show interest in a psychological intervention also actually take part in the intervention and profit from it.Clinical Trial Registration: DRKS00017426.

Body dysmorphia in common skin diseases: Results of an observational, cross-sectional multi-centre study among dermatological out-patients in 17 European countries

BACKGROUND

Body dysmorphic disorder (BDD) is a common psychiatric disorder associated with high costs for healthcare systems as patients may repeatedly ask for different, often not effective interventions. BDD symptoms are more prevalent in patients with dermatological conditions than the general population, but there are no large sample studies comparing the prevalence of BDD symptoms between patients with dermatological conditions and healthy skin controls.

OBJECTIVES

To compare the prevalence of BDD symptoms between patients with different dermatological conditions and healthy skin controls and to describe sociodemographic, physical and psychological factors associated with BDD symptoms to identify patients who may have a particularly high chance of having this condition.

METHODS

This observational cross-sectional, comparative multi-centre study included 8295 participants: 5487 consecutive patients with different skin diseases (56% female) recruited among dermatological out-patients at 22 clinics in 17 European countries and 2808 healthy skin controls (66% female). All patients were examined by a dermatologist. BDD symptoms were assessed by the Dysmorphic Concern Questionnaire (DCQ). Sociodemographic data, information on psychological factors and physical conditions were collected. Each patient was given a dermatological diagnosis according to ICD-10 by a dermatologist.

RESULTS

The participation rate of invited dermatological patients was 82.4% on average across all centres. BDD symptoms were five times more prevalent in patients with dermatological conditions than in healthy skin controls (10.5% vs. 2.1%). Patients with hyperhidrosis, alopecia and vitiligo had a more than eleven-fold increased chance (adjusted Odds Ratio (OR) > 11) of having BDD symptoms compared to healthy skin controls, and patients with atopic dermatitis, psoriasis, acne, hidradenitis suppurativa, prurigo and bullous diseases had a more than six-fold increased chance (adjusted OR > 6) of having BDD symptoms. Using a logistic regression model, BDD symptoms were significantly related to lower age, female sex, higher psychological stress and feelings of stigmatisation.

CONCLUSIONS

This study reveals that clinical BDD symptoms are significantly associated with common dermatological diseases. As such symptoms are associated with higher levels of psychological distress and multiple unhelpful consultations, general practitioners and dermatologists should consider BDD and refer patients when identified to an appropriate service for BDD screening and management.

Mindfulness as Predictor of Itch Catastrophizing in Patients With Atopic Dermatitis: Results of a Cross-Sectional Questionnaire Study

Itch and worry about itch are predominant symptoms in atopic dermatitis (AD). Mindfulness refers to paying attention in a certain way, non-judgementally and on purpose. In patients with chronic pain, which shares several similarities with chronic itch, a significant relationship between pain intensity, mindfulness and pain catastrophizing has been found. The aim of this study was to investigate whether itch intensity and mindfulness are related to itch catastrophizing in AD patients. Participants receiving treatment for AD (n = 155; 58 male; mean age: 46.5 ± 12 years) completed measures of itch-related catastrophizing (Itch Cognitions Questionnaire; ICQ) and mindfulness (Comprehensive Inventory of Mindfulness; CHIME) during their stay at a rehabilitation center in Borkum, Germany. In addition to other variables, their average itch intensity during the last 2 weeks was assessed by means of a visual analog scale. A positive relationship between itch intensity and itch catastrophizing was found (r = 0.409; p < 0.01). Moreover, the mindfulness scales “acting with awareness,” “accepting and non-judgemental orientation,” and “non-reactive orientation” were negatively related to itch catastrophizing. A linear regression analysis revealed that itch intensity in combination with “acting with awareness” was able to explain more than 27 % (corrected R² = 0.274; p < 0.001) of the variance of itch catastrophizing. Thus, itch intensity and certain facets of mindfulness were associated with itch catastrophizing in AD patients. Psychological interventions aiming to increase acting with awareness might have a buffering effect on itch catastrophizing, which in turn could lead to lower itch intensity in patients with AD. Future RCTs should test this hypothesis.

Investigation of predictors of interest in a brief mindfulness-based intervention and its effects in patients with psoriasis at a rehabilitation clinic (SkinMind): an observational study and randomised controlled trial

INTRODUCTION

Psoriasis (PS) is a chronic inflammatory skin disease accompanied by reduced quality of life. Mindfulness is the ability to focus on the present moment without evaluation. Findings on the effects of 8-week mindfulness trainings in patients with PS reveal positive effects on the severity of the disease and quality of life. However, it remained unclear what distinguishes patients with PS interested in psychological interventions from those without interest and whether also a shorter, namely 2-week mindfulness-based intervention is beneficial in this patient group. This will be investigated with this study.

METHODS AND ANALYSES

Data will be collected at a rehabilitation clinic in Germany. The study is divided into two parts: study 1a is an observational study. Its aim is to investigate whether sociodemographic, skin-related and psychological factors are significant predictors of interest in a brief psychological intervention in 127 patients with PS. Study 1b is a randomised controlled trial, in which 60 patients (retrieved from study 1a) will be randomised to an intervention or control group (treatment as usual). The main outcome variables are mindfulness and self-compassion. In addition, mediation analyses will be used in an explorative manner to test whether there is a relationship between mindfulness/self-compassion and the severity of PS and whether it is mediated by itch catastrophising and fear of negative evaluation (first model) or perceived stress (second model).

ETHICS AND DISSEMINATION

The study protocol has been approved by the University of Giessen. Study results will be disseminated by publication of the results at (inter) national conferences and in scientific journals.

'The psychosocial burden of alopecia areata and androgenetica': a cross-sectional multicentre study among dermatological out-patients in 13 European countries

BACKGROUND

Hair diseases play an important burden on patients' lives, causing significant emotional and psychosocial distress. However, the impairment due to different hair conditions, such as alopecia areata (AA) and androgenetic alopecia (AGA), has rarely been compared.

OBJECTIVE

The aim of this study was to assess the psychological burden of subgroups of patients with different hair diseases and to compare them to a healthy population.

METHODS

In this study, we analysed a subgroup of patients with hair diseases from patients of a large multicentre study including 3635 dermatological patients and 1359 controls from 13 European countries. In the subgroup of patients with hair diseases, we analysed the socio-demographic characteristics, the stress level, and the impact of hair diseases on quality of life (QoL), anxiety, and depression and we compared them among patients with AA, AGA and healthy controls.

RESULTS

The study population included 115 patients (77% women, 23% men) with hair diseases, 37 of whom with AA and 20 with AGA. Patients with hair diseases had a lower education level than healthy controls (medium educational level: 43% vs. 28%). Overall, 41% of the patients reported stressful life events during the last 6 months compared with 31% of the controls. Patients with the same age, sex, depression level and comorbidities had a worse QoL when suffering from AA than from AGA (Mean Dermatology Life Quality Index score: 5.8 vs. 2.5).

CONCLUSION

Patients with hair diseases are more anxious, depressed and have a lower QoL than controls.

Itch induction by audiovisual stimuli and histamine iontophoresis: a randomized, controlled noninferiority study

BACKGROUND

Previous research has mainly used skin-manipulating methods to induce itch. In comparison, itch induced by audiovisual stimuli lacks direct skin manipulation.

OBJECTIVES

The aim of this double blind, noninferiority study was to test the experimental hypothesis that itch induced by audiovisual stimuli is noninferior to itch induced by histamine iontophoresis in case of priming and without priming.

METHODS

In 80 of 160 healthy volunteers itch was induced by histamine iontophoresis, while in the other 80 itch was induced by audiovisual stimulation. Forty people in each group experienced either an initial resting phase or dermal priming. Itch intensity was measured by visual analogue scales, while scratch duration and frequency were video-recorded and evaluated by two independent raters. In addition, itch quality and location were measured by self-report.

RESULTS

Itch induced by audiovisual stimuli was inferior to itch induced by histamine iontophoresis in the absence of dermal priming. However, in the case of priming, maximal itch induced by audiovisual stimuli was not inferior to maximal itch induced by histamine iontophoresis. Additionally, differences in itch quality and location were observed.

CONCLUSIONS

The finding that maximal audiovisually-induced itch was comparable with maximal histamine itch only after priming emphasizes that attention plays a dominant role in mentally-induced itch. The comparability of maximal histamine and audiovisually-induced itch in the case of priming opens up new research opportunities. What's already known about this topic? Itch is a multidimensional sensation that is altered by, among other things, attention. To induce itch in basic research, different methods are used, which are partially invasive or cause skin manipulation. Noninvasive audiovisual stimuli can be used to induce itch. What does this study add? This study investigated whether itch induced by audiovisual stimuli is noninferior to itch induced by histamine iontophoresis. Itch induced by audiovisual stimuli is noninferior with regard to maximal intensity in the case of priming. Noninferiority was not shown in the case of no priming, emphasizing the role of attention in itch induction. Histamine and audiovisually-induced itch differ in terms of quality and location, but not in affective reaction.

The self-assessed psychological comorbidities of prurigo in European patients: a multicentre study in 13 countries

BACKGROUND

Prurigo is defined by the presence of chronic pruritus and multiple localized or generalized pruriginous lesions.

OBJECTIVE

The aim of this study was to assess the psychological burden of prurigo in patients of European countries.

METHODS

In this multicentre European study, 3635 general dermatology outpatients and 1359 controls were included. Socio-demographic data and answers to questionnaires (regarding quality of life, general health, anxiety and depression and suicidal ideation) were collected.

RESULTS

There were 27 patients with prurigo; of these, 63% were men, and the mean age was 58.6 years. Among patients with prurigo, 10 of 27 (37%) suffered from anxiety and 8 of 27 (29%) from depression. Suicidal ideation was reported in 5 of 27 (19%) patients, and for four of these five patients, suicidal ideation was related to their skin disease. These frequencies were higher in the 10 commonest dermatological diseases (including psoriasis, atopic dermatitis and leg ulcers). The impact on quality of life was severe, with a mean Dermatologic Life Quality Index (DLQI) of 12.4, with an extreme impact on quality of life for 23% of patients and a very large impact for 27% of patients.

CONCLUSION

The psychological comorbidities of prurigo are common, greater than those of other skin diseases, and their impact on quality of life is significant. Thus, it is important to study this condition and to find new treatments.

Dermatologists across Europe underestimate depression and anxiety: results from 3635 dermatological consultations

BACKGROUND

It was recently demonstrated that a significant number of patients with common skin diseases across Europe are clinically depressed and anxious. Studies have shown that physicians not trained as psychiatrists underdiagnose depression. This has not been explored among dermatologists.

OBJECTIVES

To estimate the concordance between clinical assessment of depression and anxiety by a dermatologist and assessment with the Hospital Anxiety and Depression Scale (HADS).

METHODS

The study was an observational cross-sectional multicentre study of prevalent cases of skin diseases in 13 countries in Europe. Consecutive patients were recruited in outpatient clinics and filled in questionnaires prior to clinical examination by a dermatologist who reported any diagnosis of skin disease and signs of mood disorders.

RESULTS

Analysis of the 3635 consultations showed that the agreement between dermatologist and HADS was poor to fair (lower than 0·4) for all diagnosis categories. The true-positive rate (represented by the percentage of dermatologists recognizing signs of depression or anxiety in patients with depression or anxiety as defined by a HADS value ≥ 11) was 44·0% for depression and 35·6% for anxiety. The true negative rate (represented by the percentage of dermatologists not detecting signs of depression or anxiety in non-depressed or non-anxious patients defined by HADS-value < 11) was 88.8% for depression and 85.7% for anxiety.

CONCLUSIONS

Dermatologists in Europe tend to underestimate mood disorders. The results suggest that further training for dermatologists to improve their skills in diagnosing depression and anxiety might be appropriate. When present, the psychological suffering of patients with dermatological conditions needs to be addressed.

Brain Processing of Contagious Itch in Patients with Atopic Dermatitis

Several studies show that itch and scratching cannot only be induced by pruritogens like histamine or cowhage, but also by the presentation of certain (audio-) visual stimuli like pictures on crawling insects or videos showing other people scratching. This phenomenon is coined "Contagious itch" (CI). Due to the fact that CI is more profound in patients with the chronic itchy skin disease atopic dermatitis (AD), we believe that it is highly relevant to study brain processing of CI in this group. Knowledge on brain areas involved in CI in AD-patients can provide us with useful hints regarding non-invasive treatments that AD-patients could profit from when they are confronted with itch-inducing situations in daily life. Therefore, this study investigated the brain processing of CI in AD-patients. 11 AD-patients underwent fMRI scans during the presentation of an itch inducing experimental video (EV) and a non-itch inducing control video (CV). Perfusion based brain activity was measured using arterial spin labeling functional MRI. As expected, the EV compared to the CV led to an increase in itch and scratching (p < 0.05). CI led to a significant increase in brain activity in the supplementary motor area, left ventral striatum and right orbitofrontal cortex (threshold: p < 0.001; cluster size k > 50). Moreover, itch induced by watching the EV was by trend correlated with activity in memory-related regions including the temporal cortex and the (pre-) cuneus as well as the posterior operculum, a brain region involved in itch processing (threshold: p < 0.005; cluster size k > 50). These findings suggest that the fronto-striatal circuit, which is associated with the desire to scratch, might be a target region for non-invasive treatments in AD patients.

The burden of common skin diseases assessed with the EQ5D™: a European multicentre study in 13 countries

BACKGROUND

Generic instruments measuring health-related quality of life (HRQoL), like EQ5D™, enable comparison of skin diseases with healthy populations and nondermatological medical conditions, as well as calculation of utility data.

OBJECTIVES

To measure HRQoL in patients with common skin diseases and healthy controls across Europe using the EQ5D.

METHODS

This multicentre observational cross-sectional study was conducted in 13 European countries. Each dermatology clinic recruited at least 250 consecutive adult outpatients to complete questionnaires, including the EQ5D.

RESULTS

There were 5369 participants (4010 patients and 1359 controls). Mean ± SD self-rated health state reported by patients was 69·9 ± 19·7; for controls it was 82·2 ± 15·5. When adjusted for confounding factors, including comorbidity, mean patient EQ visual analogue scores were 10·5 points lower than for controls (standardized β = -0·23). Odds ratio with 95% confidence interval for impairment in all five dimensions of EQ5D adjusted for confounders was doubled for patients compared with controls. Patients with hidradenitis suppurativa (HS), blistering conditions, leg ulcers, psoriasis and eczemas had the highest risk for reduction in HRQoL in most dimensions (2-10-fold). Data on differences of impairment by dimensions offer new insights.

CONCLUSIONS

This study confirms the large impact skin conditions have on patients' well-being, differentiating between aspects of HRQoL. Patients with HS, blistering diseases, leg ulcers, infections and most chronic skin diseases reported reduced HRQoL compared with patients with chronic obstructive lung disease, diabetes mellitus, cardiovascular disease and cancers. These findings are important in the prioritization of resource allocation between medical fields and within dermatological subspecialities.

Contagious itch: what we know and what we would like to know

All humans experience itch in the course of their life. Even a discussion on the topic of itch or seeing people scratch can evoke the desire to scratch. These events are coined “contagious itch” and are very common. We and others have shown that videos showing people scratching and pictures of affected skin or insects can induce itch in healthy persons and chronic itch patients. In our studies, patients with atopic dermatitis (AD) were more susceptible to visual itch cues than healthy. Also, personality traits like agreeableness and public self-consciousness were associated with induced scratching in skin patients, while neuroticism correlated with induced itch in healthy subjects. The underlying course of contagious itch is not yet fully understood. It is hypothesized that there are human mirror neurons that are active when we imitate actions and/or negative affect. Until now, there has been only limited data on the mechanisms of brain activation in contagious itch though. We have barely begun to understand the underlying physiological reactions and the triggering factors of this phenomenon. We summarize what we currently know about contagious itch and provide some suggestions what future research should focus on.

Effects of a structured educational intervention on knowledge and emergency management in patients at risk for anaphylaxis

BACKGROUND

Structured educational programmes for patients at risk for anaphylaxis have not yet been established. Patients and caregivers often lack adequate skills in managing the disease.

METHODS

To investigate effects of structured patient education intervention on knowledge, emergency management skills and psychological parameters in patients with previous episodes of anaphylaxis and caregivers of affected children 95 caregivers (11 male, 84 female, mean age 37 years) of affected children and 98 patients (32 male, 66 female, mean age 47.5 years) were randomly assigned to an intervention (IG) or control group (CG) in a multicentre randomized controlled trial. The IG received two 3-h schooling modules of group education; the CG received standard auto-injector training only. Knowledge of anaphylaxis and emergency management competence in a validated training anaphylaxis situation as main outcome measures as well as secondary psychological parameters were assessed at baseline and 3 months after intervention.

RESULTS

In comparison with controls, the intervention led to significant improvement of knowledge from baseline to 3-month follow-up (caregivers: IG 3.2/13.2 improvement/baseline vs CG 0.7/12.6; P < 0.001; patients: IG 3.9/10.8 vs 1.3/12.6; P < 0.001). Moreover, emergency management competence was increased after intervention as compared to controls (caregivers: IG 8.6/11.2 vs CG 1.2/10.8; P < 0.001; patients: 7.1/11.0 vs 1.1/11.1; P < 0.001). Intervention showed significant reduction of caregiver anxiety (-1.9/8.4 vs -0.7/7.5; P < 0.05). There were no significant changes in the depression scores.

CONCLUSION

Structured patient education programmes may be beneficial in the management of anaphylaxis by increasing patients' empowerment to prevent and treat the disease.

Structured education program improves the coping with atopic dermatitis in children and their parents-a multicenter, randomized controlled trial

OBJECTIVE

The objective of this study was to prove training-specific effects in children with atopic dermatitis (AD) and their parents concerning coping with the disease after their participation in a training program. In the 1-year follow-up, the changes in the training group were compared to the changes in a waiting control group while controlling the effects of the changes in severity scores.

METHODS

One hundred eighty-five children aged 8-12 years and their parents participated in the study. Complete data sets at the 1-year follow-up were available for 185 parent-child pairs (102 training group; 83 waiting control group). In addition to the severity of the AD [measured with the Scoring Atopic Dermatitis (SCORAD)], data on children's itching-scratching cognitions and coping behavior and on parents handling their affected children were used in the analysis. To study whether the intervention group experienced an additional psychological benefit, which is not due to the SCORAD values, analyses of covariance with repeated measures with standardized residual change scores of the SCORAD as covariate were calculated.

RESULTS

The intervention group showed greater improvement in children's coping behavior and in parents' handling their affected children. Additional effects of the training program not due to somatic improvement could be seen in the scales of itching-scratching cognitions and in three of four scales on parents dealing with their affected children.

CONCLUSION

The training program, which was tested in the German Atopic Dermatitis Intervention Study, had effects on almost all explored psychological variables. Therefore, additional psychological benefit in the training group does not only depend on the greater improvement of SCORAD values in this group.

[Psychosomatic dermatology]

Psychosomatic dermatology deals with skin disorders that are substantially influenced by psychosocial causes, sequelae or circumstances or in which these are important in the selection of therapy for the particular patient. In this context, skin diseases have been recognized in a biopsychosocial model for holistic medicine. In a wider sense, psychosomatic dermatology embraces every aspect of intra- and interpersonal problems relating to skin disorders and psychosomatic trigger mechanisms and/or ways of coping with skin disorders. A distinction is made between primarily psychic conflicts, psychosomatic diseases and somatopsychic aspects. Approaches to treatment take account of the doctor (doctor's-assistant)-patient relationship, compliance factors, the dermatosis patient's quality of life and the psychosocial health of the dermatologist, and also steps that can be implemented in the context of the practice management and basic psychosomatic treatment including referral for special psychotherapy.

[Atopic dermatitis and stress? How do emotions come into skin?]

It is widely accepted, that stress can induce or exacerbate atopic dermatitis. The physiological mechanisms that mediate this negative influence of stress on atopic dermatitis are not clearly understood. This topic has been actively investigated in recent years focusing on neuroimmunological, psychoendocrinological studies and examination of integrity and function of skin barrier under stress. Different neuropeptides and neurotrophins seem to play an important role in stress-induced neurogenic inflammation and connection of nervous and immune system. Mast cells play a key role in the development of inflammatory reaction to stress. Skin barrier is altered by stress by means of increased cortisol level. Thereby lamellar body secretion is decreased and epidermal expression of antimicrobial peptides (beta-defensin and cathelicidin) is down-regulated. We review recent investigations in this field.

[Health-related quality of life in dermatologists compared to other physicians]

BACKGROUND

According to recent studies, there may be differences in quality of life for physicians depending on gender and field of medicine. Presently, there are hardly any data with respect to health-related quality of life in dermatologists.

METHODS

Using the SF-36 Health Survey, 112 dermatologists and 113 physicians in other fields of medicine were studied in a cross-sectional study.

RESULTS

Dermatologists' mental health level averaged lower than their physical health level (chi2=28.49; p<.001). The mental and physical health level were higher in female dermatologists than in their male colleagues (e.g., GH: chi2=6.15; p<.05 and MH: chi2=6.83; p<.05). These findings are the opposite of results in other medical specialists. The differences between mental and physical health dimensions on the one hand, and between women and men on the other hand, were found in all age groups.

CONCLUSIONS

In comparison to other medical specialists, dermatologists differ only slightly in their health-related quality of life. Therefore, it may be advisable to implement preventive measures concerning their comparatively low mental health status.

Atopic dermatitis -- topical therapy: do patients apply much too little?

BACKGROUND

The treatment of atopic dermatitis still remains a challenge. Little research has been done on the issue of the extent to which patients correctly use prescribed topical preparations under everyday conditions.

AIMS

To investigate what quantity of topical preparations is applied by outpatients in daily routine treatment over a 26-week period and to what extent this consumption is related to the course of the severity of patients' skin conditions.

METHODS

Thirty adult outpatients (20 female and 10 male) with atopic dermatitis were examined at four different times during 26 weeks. For treatment and skin care these patients were given a topical glucocorticoid preparation (prednicarbate) and the corresponding emollient.

RESULTS

The average severity rating (SCORAD) was 29.6 (before therapy 33.9, after 26 weeks 27.4). The SCORAD indices improved by a mean of 6.5 points (p<0.05).

CONCLUSION

Patients who applied the correct amount of the prednicarbate-containing preparations (not less than 90% of 0.5 g/dm(2)) to the areas of affected skin showed a significant improvement in SCORAD indices across the four measuring times.

[Prevalence of psychosomatic disorders in dermatologic patients. Experiences in 2 dermatology clinics with a liaison therapy model]

INTRODUCTION

The prevalences and differences of biopsychosocial disorders were investigated in the dermatologic clinics of Erfurt and Giessen, where a liaison-therapy model has been established. Different dermatological diseases were compared by a variety of psychological tests, and patients with the same diagnosis were compared between the two clinics.

PATIENTS AND METHODS

We examined 406 patients for psychosomatic problems with diagnostic interviews and psychometric tests. The coping of skin disease questionnaire (CSD) and the Symptom Checklist (SCL-90R) served as diagnostic measures. Between 1995-2000, 71 patients were seen in Erfurt and 335 in Giessen. The distribution of skin diseases and the psychosomatic disorders are shown by ICD-10 diagnoses.

RESULTS

The comparison of an East and a West German city showed no significant differences in the whole group or the parallel groups using the CSD and SCL-90R. There was only a tendency to a greater reduction of quality of life in Erfurt. Patients with glossodynia evaluated themselves in all psychometric tests as very "normal". By contrast, patients suffering from alopecia and acne felt very helpless and seemed to have a need of greater psychosocial care.

CONCLUSIONS

The biopsychosocial characteristics of the patients treated in the dermato-psychosomatic units in Erfurt and Giessen show no significant differences. Patients with diseases such as alopecia and acne are underestimated in regard to the need for additional psychosocial care. The liaison therapy model is an effective approach to diagnose psychosomatic-dermatological disorders and decide if further psychosomatic treatment is indicated.

Psychological factors associated with hand dermatoses: which subgroup needs additional psychological care?

BACKGROUND

The aetiology of hand dermatoses (HD) is very heterogeneous. Psychological influences on severity and coping in hand eczema have been only rarely investigated.

OBJECTIVES

To investigate whether psychological factors correlate with somatic factors, in order to be able to estimate the possible need for psychosocial treatment of these patients.

METHODS

In a cross-sectional study 101 hand dermatosis patients (49F, 52M) with psoriasis (n = 26), vesicular hand eczema (n = 33) or contact dermatitis (n = 42) were examined with regard to dermatological [diagnosis, severity, Erlanger Atopy Score (EAS)], allergic (patch test) and psychological aspects [Coping with Chronic Skin Diseases questionnaire (CSD), Allover Depression Scale (ADS), Social Readjustment Rating Scale (SRRS), questionnaire for measuring Factors of Aggression (FAF)],and Visual Analogue Scales (VAS) concerning itching, scratching and impairment. Subgroups of high stress responders (high-SR) vs. low stress responders (low-SR) were also examined.

RESULTS

Of the patients with HD, 47.52% are convinced that 'stress' influences the course of their disease. Analysis of variance shows that the subjective reaction to stress (high-SR) correlates with higher severity scores, more itching, higher depression scores and more life events. High-SRs were younger and the onset of the disease was earlier compared with patients without a subjective reaction to stress (low-SR). In the CSD those with especially high-SR but negative patch-test results stated significantly higher values for itching, helplessness and search for information.

CONCLUSIONS

Psychological factors should be taken into consideration in the treatment of patients with HD. High-SR patients with a negative patch-test seem to require more adjuvant psychological care.
