Relaxation therapies in the treatment of psoriasis and possible pathophysiologic mechanisms

The immunomodulatory effects of social isolation in mice are linked to temperature control

Living in isolation is considered an emerging societal problem that negatively affects the physical wellbeing of its sufferers in ways that we are just starting to appreciate. This study investigates the immunomodulatory effects of social isolation in mice, utilising a two-week program of sole cage occupancy followed by the testing of immune-inflammatory resilience to bacterial sepsis. Our results revealed that mice housed in social isolation showed an increased ability to clear bacterial infection compared to control socially housed animals. These effects were associated with specific changes in whole blood gene expression profile and an increased production of classical pro-inflammatory cytokines. Interestingly, equipping socially isolated mice with artificial nests as a substitute for their natural huddling behaviour reversed the increased resistance to bacterial sepsis. Together these results suggest that the control of body temperature through social housing and huddling behaviour are important factors in the regulation of the host immune response to infection in mice and might provide another example of the many ways by which living conditions influence immunity.

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.

Clinical, Pathological and Immunohistochemical Effects of Arsenical-Ferruginous SPA Waters on Mild-To-Moderate Psoriatic Lesions: A Randomized Placebo-Controlled Study

Thermalism and spa treatments are traditionally considered effective in a number of dermatologic inflammatory conditions, yet there is scarce evidence about spring water effectiveness on psoriasis in a daily setting. We enrolled 34 patients with mild-to-moderate psoriasis in a double-blind, randomized, placebo-contralaterally-controlled trial, to evaluate Levico and Vetriolo arsenical-ferruginous water effectiveness on psoriatic lesions by daily 20-minute wet packing for 12 consecutive days. Clinical, histopathologic and immunohistochemical parameters were considered. A statistically significant difference between spa water-treated lesions and placebo-treated lesions in the same patients was demonstrated for histopathologic and immunohistochemical parameters. Since iron ions have an antiproliferative effect on epithelia, and magnesium ions have an anti-inflammatory effect, Levico and Vetriolo water effectiveness on psoriasis could be addressed to their content of these ions.

Complementary Psychocutaneous Therapies in Dermatology

The skin and the nervous system develop side by side in the fetus and remain intimately interconnected and interactive throughout life. Because of the skin-nervous system interactions, there is a significant psychosomatic or behavioral component to many dermatologic conditions. This permits complementary nonpharmacologic psychotherapeutic interventions, such as acupuncture, aromatherapy, biofeedback, cognitive-behavioral therapy, hypnosis, placebo, and suggestion, to have positive impacts on many dermatologic diseases. Complementary pharmacologic psychotherapeutic interventions, such as herbs and supplements, also may help improve some dermatologic disorders.

Biofeedback, cognitive-behavioral methods, and hypnosis in dermatology: is it all in your mind?

Biofeedback can improve cutaneous problems that have an autonomic nervous system component. Examples include biofeedback of galvanic skin resistance (GSR) for hyperhidrosis and biofeedback of skin temperature for Raynaud's disease. Hypnosis may enhance the effects obtained by biofeedback. Cognitive-behavioral methods may resolve dysfunctional thought patterns (cognitive) or actions (behavioral) that damage the skin or interfere with dermatologic therapy. Responsive diseases include acne excoriée, atopic dermatitis, factitious cheilitis, hyperhidrosis, lichen simplex chronicus, needle phobia, neurodermatitis, onychotillomania, prurigo nodularis, trichotillomania, and urticaria. Hypnosis can facilitate aversive therapy and enhance desensitization and other cognitive-behavioral methods. Hypnosis may improve or resolve numerous dermatoses. Examples include acne excoriée, alopecia areata, atopic dermatitis, congenital ichthyosiform erythroderma, dyshidrotic dermatitis, erythromelalgia, furuncles, glossodynia, herpes simplex, hyperhidrosis, ichthyosis vulgaris, lichen planus, neurodermatitis, nummular dermatitis, postherpetic neuralgia, pruritus, psoriasis, rosacea, trichotillomania, urticaria, verruca vulgaris, and vitiligo. Hypnosis can also reduce the anxiety and pain associated with dermatologic procedures.

Extended, strategic therapy for recalcitrant mind/body healing: an integrative model

The development of the power therapies, behavioral medicine, and short term interventions have reported such success even with trauma cases that it is relevant to question the justification for lengthy psychotherapy. Yet some patients with complex mind/body conditions impervious to medical treatment/hypnosis may require extended, multi-modal, integrative therapy. This paper details a single complex case of paruresis as a prototype for illustrating a holographic treatment model for recalcitrant conditions: Component features of the proposed model presented include: 1) the sequential utilization of hypnobehavioral and analytic approaches; 2) uncovering work providing access to the somatic ego state associated with the illness condition; 3) the extended treatment time frame required for deep psycho-physiological change; and 4) the stages of counter-transference expectably evoked by such patients (e.g. urgency, exuberant optimism, frustration, discouragement), and the transformation of such reactions to achieve maximum therapeutic efficacy.

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.

Adjusting to disfigurement: processes involved in dealing with being visibly different

This paper reviews current psychological understandings of the process of adjustment to acquired and congenital disfiguring conditions, such as burns, dermatological diseases, and cleft palate. It is primarily aimed at researchers and clinicians interested in understanding and ameliorating the psychosocial impact of such disfigurements. The literature was accessed using psychological, medical, and nursing databases. The research indicates that the experience of disfigurement is multifaceted, involving individual and societal factors. The adjustment process involves the way that disfigured people interpret their disfigurement, their self, and their encounters with others. These interpretations are likely to be influenced by the interaction between various underlying cognitive self-schemas and the social context. Efficacious interventions provide disfigured people with practical strategies to deal with social encounters and/or tackle underlying cognitive processes. However, many of the studies examined were methodologically limited or uninformed by psychological theory. Future research is needed to gain a better appreciation of the experience of living with a disfigurement and to inform the development of effective clinical interventions. In particular, there is a need for studies using longitudinal and qualitative methologies, as this would foster greater understanding of the psychological and emotional processes involved in adjusting to disfiguring conditions.

Empirical findings on the use of hypnosis in medicine: a critical review

Recent changes in health care have been characterized by an increased demand for empirically supported treatments in medicine. Presently, there is moderate support for the integration of hypnotic techniques in the treatment of a number of medical problems. This critical review of the research literature focuses on the empirical research on the effectiveness of hypnotic treatments as adjuncts to medical care for anxiety related to medical and dental procedures, asthma, dermatological diseases, gastrointestinal diseases, hemorrhagic disorders, nausea and emesis in oncology, and obstetrics/gynecology. Wider acceptance of hypnosis as an intervention to assist with medical care will require further research.

Systemic aspects of psoriasis. An integrative model based on intestinal etiology

Psoriasis can best be understood from a multifactorial approach that recognizes the systemic aspects of the disorder. Among the various factors thought to be involved in the etiology and pathogenesis of psoriasis, bowel pathology has assumed a noteworthy position in the literature. This article reviews the psoriasis/bowel connection with regard to abnormal bowel structure and physiology in psoriasis patients. Clinical implications of bowel involvement in psoriasis are discussed within the framework of an integrative medicine model that emphasizes natural therapeutics for addressing the systemic aspects of the illness.

Influence of a mindfulness meditation-based stress reduction intervention on rates of skin clearing in patients with moderate to severe psoriasis undergoing phototherapy (UVB) and photochemotherapy (PUVA)

OBJECTIVE

This study tests the hypothesis that stress reduction methods based on mindfulness meditation can positively influence the rate at which psoriasis clears in patients undergoing phototherapy or photochemotherapy treatment.

METHODS

Thirty-seven patients with psoriasis about to undergo ultraviolet phototherapy (UVB) or photochemotherapy (PUVA) were randomly assigned to one of two conditions: a mindfulness meditation-based stress reduction intervention guided by audiotaped instructions during light treatments, or a control condition consisting of the light treatments alone with no taped instructions. Psoriasis status was assessed in three ways: direct inspection by unblinded clinic nurses; direct inspection by physicians blinded to the patient's study condition (tape or no-tape); and blinded physician evaluation of photographs of psoriasis lesions. Four sequential indicators of skin status were monitored during the study: a First Response Point, a Turning Point, a Halfway Point, and a Clearing Point.

RESULTS

Cox-proportional hazards regression analysis showed that subjects in the tape groups reached the Halfway Point (p = .013) and the Clearing Point (p = .033) significantly more rapidly than those in the no-tape condition, for both UVB and PUVA treatments.

CONCLUSIONS

A brief mindfulness meditation-based stress reduction intervention delivered by audiotape during ultraviolet light therapy can increase the rate of resolution of psoriatic lesions in patients with psoriasis.

Factors influencing psoriasis: an analysis based upon the extent of involvement and clinical type

A variety of external stimuli are accepted as important in modifying the severity of psoriasis. We sought to determine whether there is any difference in the influence of external factors on psoriasis in relation to extent of involvement or clinical type. A total of 870 psoriasis patients seen between 1982 and 1995 were categorized as mild, moderate, or severe on the basis of extent of the disease, and as guttate, nummular/plaque, or exfoliative/generalized pustular according to clinical type. We then performed a questionnaire survey concerning the influence of external factors such as seasonal changes, sunlight, stress, and pregnancy. These data sets were combined and analysed. The majority of patients stated favorable effects of summer, sunlight, and pregnancy and adverse effects of winter and stress. A statistically significant correlation was noted between the extent of psoriasis and the proportion of patients stating that their disease worsened at times of psychological stress (p < 0.01). We confirmed that psoriasis patients with more extensive involvement experience greater fluctuations in their condition, notice these changes, and therefore relate them to psychological stress.

Psychologic effects of vitiligo: a critical incident analysis

BACKGROUND

Qualitative and quantitative studies have shown that cutaneous diseases can have significant effects on psychologic well-being and social functioning in a variety of interpersonal situations.

OBJECTIVE

Our purpose was to assess the nature and extent of the social and psychologic difficulties associated with vitiligo using a combination of qualitative and quantitative methods.

METHODS

Six hundred fourteen members of the U.K. Vitiligo Society completed a questionnaire that included the 12-item version of the General Health Questionnaire (GHQ) and an open-ended question concerning the effects of the disease on their life.

RESULTS

Thirty-five percent of the respondents scored above the threshold on the GHQ. Analysis of the qualitative data indicated that vitiligo affects lives in a variety of ways consistent with perceived stigma and that some categories of response (such as avoidance of activities and negative reactions by others) were associated with higher GHQ scores.

CONCLUSION

Many persons with vitiligo show indications of significant distress that are related to specific types of social encounters and emotional disturbance.

The relationship between stress and the onset and exacerbation of psoriasis and other skin conditions

The role of stressful life events in the progress of various skin conditions was studied retrospectively in patients who presented with either psoriasis (where there is some agreement about the importance of stress), urticaria, acne, alopecia and non-atopic eczema (where there is some uncertainty regarding the role of stress), or malignant melanoma, fungal infection, basal cell carcinoma and melanocytic naevi (where stress is considered less relevant). When patients in the three groups were matched for age, those with psoriasis were more likely to report that the experience of stress pre-dated the onset and exacerbations of their condition than patients with other skin diseases. For the psoriasis patients the most common types of life events were family upsets (such as bereavements), and work or school demands, but chronic difficulties were also common. There was no relationship between the severity of stress and time to onset or exacerbations. The results support the notion that stress is more likely to be associated with the onset of psoriasis than other conditions, but also that there may be considerable individual variation in the ability to cope, suggesting that psychological interventions may be helpful for particular patients.

Increase and decrease of delayed cutaneous reactions obtained by hypnotic suggestions during sensitization. Studies on dinitrochlorobenzene and diphenylcyclopropenone

Cutaneous reactivity to challenge with dinitrochlorobenzene (DNCB) and diphenylcyclopropenone (DCP) was studied in 16 volunteers following hypnotic suggestions to increase and decrease response during sensitization. The immunoreactivity to DNCB and DCP was modulated by direct suggestions and guided imagery under hypnosis. The volunteers were highly susceptible subjects selected by means of the Harvard Group Scale of Hypnotic Susceptibility, Form A. Measurement of skin reactions to the challenge 1 month after sensitization was performed double blindly. Results showed a significant (P < 0.01) difference in visually scored reactions to DCP and DNCB between the group instructed to increase reaction to DCP and decrease reaction to DNCB and the group given the opposite instructions. A non-significant difference (P = 0.055) in skin thickness measured by ultrasound was found between the two groups. The study supports previous reports of experimental modulation of immunoreactivity and indicates that the specific immunological processes involved in the development of allergic reactions may be susceptible to psychological factors.

Psoriasis patient support group and self-care efficacy as an adjunct to day care center treatment

Patients treated with chronic disabling psoriasis often have psychosocial concerns that need to be addressed. The weekly patient support group at Stanford, led by a psychiatrist, is an integral part of the Psoriasis Day Care program. Although not considered group therapy in the traditional sense due to its self-selective nature, the support group aims to reduce feelings of isolation and to enhance coping skills and self-efficacy. In this setting, patients explore their feelings about psoriasis enabling them to better adapt to a visible disease. Common topics for discussion include lifestyle changes, stressful relationships, associated emotional reactions, occupational limitations, and treatment concerns. Components of the Psoriasis Day Care Center that enhance treatment response and responsibility for self-care include: health education, psychosocial support systems, stress reduction, and enhanced coping skills acquired through shared experiences with other patients and medical personnel.

A psychocutaneous profile of psoriasis patients who are stress reactors. A study of 127 patients

Psoriasis is a chronic, relapsing, cutaneous condition with a 1%-2% prevalence in the general population. About 40% of psoriatics report that psychosocial stress significantly exacerbates their condition. However, the clinical characteristics of the subgroup of psoriatic patients who are stress reactors have not been delineated. At a practical clinical level it is therefore difficult to implement specific psychosocial treatments among the psoriatic population. In this study, we compared the psychocutaneous characteristics of patients who reported that stress exacerbated their psoriasis, i.e., the high stress reactors (N = 64) to the subgroup who reported no significant association between stress and their psoriasis, i.e., the low stress reactors (N = 63). The high stress reactors had more disfiguring disease clinically (p less than 0.02); psychologically they tended to rely more upon the approval of others (p less than 0.05) and experienced more psoriasis-related daily stress (p less than 0.005). The high stress reactors also reported more flare-ups of their psoriasis during the 6 months prior to admission (p less than 0.05). We have shown that the high stress reactors can be clinically delineated from the low stress reactors. Certain psychosocial interventions will most likely decrease the morbidity associated with psoriasis among the high stress reactors, and may possibly even result in a decline in the number of major flare-ups of the psoriasis.

Stress and psoriasis: the importance of insight and empathy in prognosis

The literature concerning the relationship between psoriasis and stress is reviewed. It is concluded that emotional stress is a significant precipitating factor. Treatment of stress is prognostically beneficial when patients understand the stress flare phenomenon and gain insight into the nature of any emotional trauma they have suppressed. Details of such insight are given and a consultation setting is described that has helped gain such rapport. It is shown that a significantly improved prognosis follows early and complete clearing of the rash.
