Biofeedback treatment of atopic dermatitis: controlled case studies of eight cases

Integrative Treatment Approaches with Mind-Body Therapies in the Management of Atopic Dermatitis

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a complex pathophysiology characterized by intense pruritus, often associated with psychological stress and atopic and non-atopic comorbidities that significantly reduce quality of life. The psychological aspects of AD and the interaction between the mind and body via the skin-brain axis have led to an interest in mind-body therapies (MBT). The aim of this article is, therefore, to reinforce the importance of psychodermatological care in AD. We performed a focused literature review on holistic practices or integrative MBT in AD, including education, cognitive behavioral therapy, habit reversal, meditation, mindfulness, hypnotherapy, eye movement desensitization and reprocessing, biofeedback, progressive muscle relaxation, autonomous sensory meridian response, music therapy, massage, and touch therapy. A multidisciplinary holistic approach with MBT, in addition to conventional pharmacologic antipruritic therapies, to break the itch-scratch cycle may improve AD outcomes and psychological well-being. Although there is a paucity of rigorously designed trials, evidence shows the potential benefits of an integrative approach on pruritus, pain, psychological stress, anxiety, depressive symptoms, and sleep quality. Relaxation and various behavioral interventions, such as habit reversal therapy for replacing harmful scratching with massaging with emollient 'plus', may reduce the urge to scratch, while education may improve adherence to conventional therapies.

Experiences with the first eczema school in the United States

Patient education programs are beneficial in the treatment of chronic diseases. In Germany, France, and other countries worldwide, educating children, adolescents, and adults plus the parents of children with atopic dermatitis (AD) leads to better coping with the skin disease, as well as to a reduction in the severity of the skin symptoms and signs. The results in Europe led to the idea to also establish an eczema school in the United States. In the style of the German eczema school, an eczema school was founded in 2014 at Temple University, Philadelphia, PA. Since then, a team consisting of a dermatologist, psychologist, nutritionist, and nurse practitioner has offered an eczema school to interested patients with AD and their families three times a year. This patient education program consists of three weekly 2-hour sessions, which address proper skin care, the itch-scratch cycle, healthy nutrition, and the role of stress in AD. The current review summarizes the first experiences with the education program in the United States.

The Role of Psychological Stress in Skin Disease

Background:

Numerous case reports and studies have suggested that psychological stress may have a role in the onset or exacerbation of a variety of skin diseases.

Objective:

We review the literature pertaining to the role of psychological stress in the exacerbation of psoriasis, urticaria, eczematous dermatitis, herpesvirus infections, and other skin diseases; discuss potential mechanisms of stress-induced skin disease; and review studies and case reports of psychotherapeutic interventions that have been found helpful in the therapy of skin diseases.

Conclusions:

There is evidence linking psychological stress to exacerbation of certain skin diseases. Both the clinical and the basic science evidence, however, can be hard to interpret in light of the difficulty of defining and quantifying psychological stress as well as the questions regarding the etiologic significance of neuroimmunologic findings in skin diseases.

Cognitive Behavioural Stress Management as Treatment of Atopic Dermatitis: A Case Study

A 37-year-old male with a 13-year history of atopic dermatitis (AD) was treated with cognitive behavioural stress management. Self-rated stress and extent of AD rash decreased from baseline to the end of treatment, and gains were maintained at follow-up. A significant correlation between stress and extent of AD rash was observed. Discussion focused on the possible role of stress induced immunosuppression on exacerbations of AD, and the need for controlled trials evaluating the treatment procedures used in the current study.

Further exploring the brain-skin connection: stress worsens dermatitis via substance P-dependent neurogenic inflammation in mice

A neurogenic component in atopy and allergy is evident and potentially of great pathogenic relevance. Stress was recently shown to activate elements of this component and is vividly discussed as a cause of exacerbation. However, to date, scientific proof of stress-induced neuronal plasticity and neuro-immune interaction in atopy or allergy remains lacking. Here we show early evidence that exposure to sound stress and atopic dermatitis-like allergic dermatitis (AD) equipotently raise the number of cutaneous nerve fibers containing the prototypic stress neuropeptide substance P (SP) in mice. Stress increases AD readout parameters by at least 30% (eosinophil infiltration, vascular cell adhesion molecule-positive blood vessels, epidermal thickness). This dramatic pathologic exacerbation is associated with increased neurogenic inflammation (degranulated mast cells; interstitial neuropeptidergic dense core granules, mast cell apoptosis, endothelial gaping). Key features of AD exacerbation could not be induced in mice lacking the neurokinin-1 SP receptor (NK1). Interestingly, stress had no significant additional effect on CD4+ cell number, but shifted the cytokine profile toward TH2 in skin. Thus, we conclude that stress primarily exacerbates AD via SP-dependent cutaneous neurogenic inflammation and subsequent local cytokine shifting and should be considered as a therapeutic target, while it offers a convincing pathogenic explanation to affected patients and their frustrated physicians alike.

Psychological and educational interventions for atopic eczema in children

BACKGROUND

Psychological and educational interventions have been used as an adjunct to conventional therapy for children with atopic eczema to enhance the effectiveness of topical therapy. There have been no relevant systematic reviews applicable to children.

OBJECTIVES

To assess the effectiveness of psychological and educational interventions in changing outcomes for children with atopic eczema.

SEARCH STRATEGY

We searched the Cochrane Skin Group Specialised Register (to September 2004), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 2, 2005), MEDLINE (from 1966-2005), EMBASE (from 1980 to week 3, 2005 ), PsycINFO (from 1872 to week 1, 2005). On-line: National Research Register, Meta-register of Controlled Trials, ZETOC alerts, SIGLE (August 2005).

SELECTION CRITERIA

RCTs of psychological or educational interventions, or both, used to manage children with atopic eczema.

DATA COLLECTION AND ANALYSIS

Two authors independently applied eligibility criteria, assessed trial quality and extracted data. A lack of comparable data prevented data synthesis.

MAIN RESULTS

Five RCTs met the inclusion criteria. Some included studies required clearer reporting of trial procedures. Rigorous established outcome measures were not always used. Interventions described in all 5 RCTs were adjuncts to conventional therapy. Four focused on intervention directed towards the parents; data synthesis was not possible. Psychological interventions remain virtually unevaluated by studies of robust design; the only included study examined the effect of relaxation techniques (hypnotherapy and biofeedback) on severity. Three educational studies identified significant improvements in disease severity between intervention groups. A recent German trial evaluated long term outcomes and found significant improvements in both disease severity (3 months to 7 years, p=0.0002, 8 to 12 years, p=0.003, 13 to 18 years, p=0.0001) and parental quality of life (3 months to 7 years, p=0.0001, 8 to 12 years p=0.002), for children with atopic eczema. One study found video-based education more effective in improving severity than direct education and the control (discussion) (p<0.001). The single psychological study found relaxation techniques improved clinical severity as compared to the control at 20 weeks (t=2.13) but this was of borderline significance (p=0.042).

AUTHORS' CONCLUSIONS

A lack of rigorously designed trials (excluding one recent German study) provides only limited evidence of the effectiveness of educational and psychological interventions in helping to manage the condition of children with atopic eczema. Evidence from included studies and also adult studies indicates that different service delivery models (multi-professional eczema school and nurse-led clinics) require further and comparative evaluation to examine their cost-effectiveness and suitability for different health systems.

Nonpharmacologic treatments in psychodermatology

The author believes that psychocutaneous medicine has indeed come of age and is being incorporated into mainstream medical practice. Patients presenting to dermatologists today are more sophisticated and are frequently dissatisfied with traditional medical therapies. They actively seek alternative approaches and adjuncts to standard treatments. In contrast to many other "alternative" (or) "holistic" treatments offered through non-medical venues, dermatologists can assure their patients that controlled studies support the efficacy of psychocutaneous techniques in improving many dermatologic conditions. Psoriasis, rosacea, herpes simplex, body dysmorphic disorder, acne, eczema, urticaria, neurotic excoriations, excoriated acne, trichotillomania, dysesthetic syndromes, and delusions parasitosis are included in this incomplete list. The author believes it is helpful for both the patient and therapist to define concrete and realistic goals for psychocutaneous intervention. Concrete observable or measurable goals can help the patient and clinician gauge therapeutic progress and success. Specifically, goals can include reduction in pruritus (rating severity from 1-10), decreased scratching activity, decreased plaque extent or thickness, decreased number of urticarial plaques, decreased flushing, decreased anxiety, decreased anger, decreased social embarrassment, decreased social withdrawal, and improved sleep. More global goals can include an improved sense of well-being, increased sense of control, and enhanced acceptance of some of the inevitable aspects of a given skin disease. Cure should never be a goal, because most disorders amenable to psychocutaneous techniques are chronic in nature; thus, cure as an endpoint would only lead to disappointment. The author encourages dermatologists to align themselves with what he euphemistically calls "a skin-emotion specialist." The skin-emotion specialist may be a psychiatrist, psychologist, social worker, biofeedback therapist, or other mental health or behavioral specialist. Patients are more likely to accept a referral to a "skin-emotion specialist," because this term destigmatizes psychologic interventions. Incorporating these techniques and specialists into a clinical practice will expand therapeutic horizons and improve the quality of life of many of the patients afflicted with chronic skin disease. A final caveat must be offered about attempting to make prognostic statements regarding the likelihood of therapeutic success. Although all patients can potentially benefit from psychocutaneous interventions, those with severe psychopathology and poor pretreatment functional status are likely to be more difficult to treat and to achieve less optimal outcomes. Patients with personality disorders such as borderline, narcissistic, and schizotypal disorders, and patients with any active psychotic process certainly constitute a more resistant and difficult population with whom therapeutic success is less likely. These patients, however, are often the ones in the greatest subjective distress and certainly can profit from any of the described interventions. Quoting W. Mitchell Sams, Jr., "although the physician is a scientist and clinician, he or she is and must be something more. A doctor is a caretaker of the patient's person--a professional advisor, guiding the patient through some of life's most difficult journeys. Only the clergy share this responsibility with us." This commitment is and must always be the guiding force in the provision of comprehensive and compatient patient care.

Treatment of acne vulgaris by biofeedback relaxation and cognitive imagery

A multielement intervention involving biofeedback-assisted relaxation and cognitive imagery treatment of acne vulgaris was investigated in this study with 30 patients receiving medical dermatological treatment. Patients were matched on age, sex, and pre-treatment acne severity and randomly assigned to groups. Treatment consisted of 12 sessions over six weeks and resulted in a significant reduction in acne severity as compared to the attention-comparison and medical control groups. Treatment group patients continuing home practice until follow-up maintained their gains, whereas those who discontinued failed to maintain gains.

Clinical psychology in the management of pediatric skin disease

The role of psychological factors in certain dermatological conditions is not disputed; however, these processes have been much more thoroughly explored in adult populations than in pediatric populations. Therefore, this article reviews relevant adult and child studies. This article explores three aspects of psychological functioning as they relate to dermatological conditions and their treatment, specifically stress and emotional regulation, behavioral and environmental issues, and compliance. The goal of this article is to give the practicing dermatologist a working overview of psychological factors in pediatric skin disease which will facilitate good communication with families around these issues and referral for adjunctive psychological treatment as needed.

Psychodermatology: an update

It has been estimated that in at least one third of dermatology patients, effective management of the skin disorder involves consideration of associated emotional factors. This article provides an overview of psychodermatology with a focus on the more recent literature and an emphasis on the clinical aspects and psychologic therapies for (1) cutaneous associations of psychiatric disorders and (2) psychiatric associations of certain cutaneous disorders that are known to be influenced by psychosomatic factors. This article also provides an update on the use of psychotropic drugs (i.e., the antianxiety, antidepressant, and antipsychotic agents) for the treatment of mental disorders that occur in conjunction with cutaneous conditions. Some of their other pharmacologic properties, such as the antihistaminic and analgesic effects of some antidepressant agents are also reviewed.

Hypnotherapy as a treatment for atopic dermatitis in adults and children

Eighteen adults with extensive atopic dermatitis, resistant to conventional treatment, were treated by hypnotherapy, with statistically significant benefit (P < 0.01) measured both subjectively and objectively, which was maintained at up to 2 years where results were available. Twenty children with severe, resistant atopic dermatitis were treated by hypnosis. All but one showed immediate improvement, which was maintained at the following two clinic appointments. In 12 children, replies to a questionnaire at up to 18 months after treatment, showed that 10 had maintained improvement in itching and scratching, nine in sleep disturbance, and seven maintained improvement in itching and scratching, nine in sleep disturbance, and seven maintained improvement in mood.

Psychotherapy for intractable inflammatory dermatoses

BACKGROUND

Most patients with inflammatory dermatoses respond to conventional treatment. Recalcitrance may indicate underlying emotional factors after infection, contact allergy, and noncompliance have been ruled out. Psychiatric treatment has been reported to be effective.

OBJECTIVE

The purpose was to determine whether insight-oriented psychotherapy, by effecting last change, would provide long-term cutaneous and psychiatric improvement.

METHODS

On the basis of emotional distress attributed to a recalcitrant inflammatory dermatosis, four patients were referred for psychiatric evaluation. The effect of adding insight-oriented psychotherapy as the only change in the treatment regimen of each patient was studied. Each patient served as his or her own control.

RESULTS

In each patient clearing of the previously recalcitrant dermatosis accompanied psychiatric improvement.

CONCLUSION

In selected cases of recalcitrant inflammatory dermatoses, insight-oriented psychotherapy may provide lasting cutaneous improvement and improved life adjustment and psychologic well-being.

Role of emotional factors in adults with atopic dermatitis

BACKGROUND

The role of anger in the onset or perpetuation of episodes of atopic dermatitis in adults has long been considered an important factor. The objective was to investigate whether atopic patients feel ineffective in dealing with anger and assertiveness when compared with psoriasis patients and control patients.

METHODS

Thirty-four adult patients with atopic dermatitis were compared to 28 patients with psoriasis and 32 controls, dental patients without major skin disease. Standard measures of anxiety, anger, assertion, depression, and locus of control as well as a measure of anger effectiveness, designed for this study, were used.

RESULTS

There were significant differences between atopic dermatitis patients and controls in that atopics felt angry more readily but were less likely to express it, were more anxious and less assertive, and felt less effective in expressing anger. The only difference between psoriasis patients and controls was less ability to express anger. Atopic patients were more chronically anxious than those with psoriasis.

CONCLUSIONS

Adult atopic dermatitis patients are often chronically anxious and feel ineffective in handling anger which suggests that psychological interventions may prove helpful.

Treatment of eczema by EMG biofeedback and relaxation training: a multiple baseline analysis

Five adults who suffered from eczema for at least five years were treated in a multiple baseline design with EMG biofeedback and progressive relaxation. Treatment consisted of five weekly EMG training sessions combined with regular home practice of relaxation. Three dependent measures were used to assess treatment effects: (1) daily self-monitoring of symptom irritation levels, (2) pre and post assessments of eczema affected areas and (3) the Spielberger Trait Anxiety Questionnaire which was also administered on a pre-post basis. Results showed clinically meaningful improvements in all five participants which were maintained at a two month follow-up. A second follow-up two years later showed that three of subjects were asymptomatic. The other two subjects could not be located. Taken together, the study provides evidence that EMG biofeedback combined with home practice of progressive relaxation can help to reduce the severity of eczema and the irritation associated with the disorder.

Psychological and behavioral factors in dermatitis

Dermatitis and eczema are described in terms of physiological, psychological, and behavioral characteristics in the sparse psychological literature on this phenomenon. Knowledge is quite limited. Lacking are prospective studies that might demonstrate whether the psychological and behavioral characteristics ate etiological and not merely descriptive. Given the number of persons estimated to experience symptoms of dermatitis (7 to 24 per 1000), further research is warranted on the relationship among dermatitis, scratching, and the psychological factors of stress, aggression, hostility, or other moods. Methodological suggestions and an experimental design are proposed.

The relation of stress and family environment to atopic dermatitis symptoms in children

The relation of stress and family environment to symptom severity in children with atopic dermatitis (AD) was examined. Forty-four children with severe AD and their families completed questionnaires measuring life events, chronic everyday problems and family environment. Measures of symptom severity were collected during medical evaluation and included an estimate of body surface affected by AD, course of AD symptoms over time, medication usage, and scratching intensity during the day and night. Regression analyses indicated that the measures of stress and family environment were important predictors of symptom severity even after controlling for demographic and medical status variables such as age and serum IgE level. These results have important implications for health care professionals working with children who have AD. Future research directions in the area of stress and AD are discussed.

An overview of atopic dermatitis: toward a bio-behavioural integration

Atopic dermatitis (AD) is a chronic, pruritic skin inflammation with suspected pathophysiological and psychological mechanisms. These factors are reviewed along with related treatment approaches. Current medical intervention for AD is palliative and only partially effective. Although encouraging, psychological treatment is not well developed and has not been adequately evaluated. It is concluded that multidisciplinary research is needed so that improved understanding and treatment of AD can be achieved.

A case study of pruritic eczema treated by relaxation and imagery

A 25-yr.-old white, married female was treated for chronic pruritic eczema through the use of frontalis EMG, relaxation, and imagery training. The biofeedback readings, ratings of the pruritus (0 to 5) and ratings of skin smoothness (0 to 5) were made over 10 sessions. Although the EMG measures did not decrease significantly, the rash disappeared completely. A 1-yr. follow-up confirmed disease control.
