Anxiety, depression, psychosomatic symptoms and autonomic nervous function in patients with chronic urticaria

Association of Sleep Duration and Weekend Catch-Up Sleep with Suicidal Ideation among Adolescents with Atopic Dermatitis

Atopic dermatitis (AD) is a prevalent allergic disease in children that often causes sleep disturbance and which is associated with diminished quality of life and heightened susceptibility to depression and suicidality. In this study, we investigate the relationship between weekend catch-up sleep (WCUS) and mental health in a sample of 71,434 adolescents with AD and 221,057 without AD using multivariate logistic regression analysis. We hypothesized that adolescents with AD experience shorter total and daytime sleep due to pruritus, with compensatory longer WCUS. We found that the lifetime prevalence of AD was 24.4%, and that adolescents with AD slept less overall, with significantly shorter weekday and weekend sleep durations but longer weekend catch-up sleep (WCUS). Sleep dissatisfaction was markedly higher in the AD group. Interestingly, our results suggest that prolonged WCUS is a protective factor against suicidal ideation in adolescents with AD. The study highlights the importance of addressing sleep patterns in adolescents with AD to enhance mental health. Overall, our findings indicate a need for increased awareness and intervention strategies to ensure sufficient sleep and reduce the risk of suicidal ideation in this population.

Prevalence, Clinical Manifestations, Treatment, and Clinical Course of Chronic Urticaria in Elderly: A Systematic Review

Purpose

Data specific to the epidemiology, clinical features, and management of chronic urticaria (CU) in the geriatric population remain limited and not well understood. We aim to systematically review the prevalence, clinical manifestations, treatment, and clinical course of elderly patients with CU.

Patients and methods

Original articles that included data of elderly (aged >60 years) with CU that were published until February 2021 were searched in PubMed, Scopus, and Embase using predfefined search terms. Related articles were evaluated according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations.

Results

Among the included 85 studies and 1,112,066 elderly CU patients, most (57.4%) were women. The prevalence of elderly CU in the general population ranged from 0.2–2.8%, and from 0.7–33.3% among all CU patients. Compared to adult CU, elderly CU patients had a higher percentage of wheal alone (73.9%), and lower rate of positive autologous serum skin test and atopy. Gastrointestinal diseases were the most common comorbidity (71.9%), and there was a high rate of malignancies and autoimmune diseases. Second generation H₁-antihistamines were commonly used, and achievement of complete control was most often reported. Omalizumab was prescribed in 59 refractory patients, and a significant response to treatment was reported in most patients. The treatment of comorbidities also yielded significant improvement in CU.

Conclusion

Elderly CU was found to be different from adult CU in both clinical and laboratory aspects. H₁- antihistamines are effective as first-line therapy with minimal side-effects at licensed doses. Treatment of secondary causes is important since the elderly usually have age-related comorbidities.

Epidemiology of urticaria in China: a population-based study

Background:

Urticaria is a common skin disease characterized by episodes of wheals, and it has a negative effect on patients’ quality of life. Large-scale population-based epidemiological studies of urticaria are scarce in China. The aim of this survey was to determine the prevalence, clinical forms, and risk factors of urticaria in the Chinese population.

Methods:

This survey was conducted in 35 cities from 31 provinces, autonomous regions, and municipalities of China. Two to three communities in each city were selected in this investigation. Participants completed questionnaires and received dermatological examinations. We analyzed the prevalence, clinical forms, and risk factors of urticaria.

Results:

In total, 44,875 questionnaires were distributed and 41,041 valid questionnaires were collected (17,563 male and 23,478 female participants). The lifetime prevalence of urticaria was 7.30%, with 8.26% in female and 6.34% in male individuals (P < 0.05). The point prevalence of urticaria was 0.75%, with 0.79% in female and 0.71% in male individuals (P < 0.05). Concomitant angioedema was found in 6.16% of patients. Adults had a higher prevalence of urticaria than adolescents and children. Living in urban areas, exposure to pollutants, an anxious or depressed psychological status, a personal and family history of allergy, thyroid diseases, and Helicobacter pylori infection were associated with a higher prevalence of urticaria. Smoking was correlated with a reduced risk of urticaria.

Conclusion:

This study demonstrated that the lifetime prevalence of urticaria was 7.30% and the point prevalence was 0.75% in the Chinese population; women had a higher prevalence of urticaria than men. Various factors were correlated with urticaria.

Explore the Underlying Mechanism Between Atopic Dermatitis and Major Depressive Disorder

Adult patients with atopic dermatitis (AD) present relatively higher rates of major depressive disorder (MDD). However, the underlying mechanism is largely unknown. Here, we first conducted a systematic literature-based data mining to identify entities linking AD and MDD, including proteins, cells, functional classes, and small molecules. Then we conducted an AD-RNA expression data-based mega-analysis to test the expression variance of the genes that were regulators of MDD. After that, a Fisher Exact test-based pathway enrichment analysis (PEA) was performed to explore the AD-driven MDD-genetic regulators’ functionality. We identified 22 AD-driven entities that were up-stream MDD regulators, including 11 genes, seven small molecules, three functional classes, and one cell. AD could exert a promoting effect on the development of MDD. Four of the 11 genes demonstrated significant expression changes in AD patients in favor of the development of MDD. PEA results showed that AD mainly drives cytokine/chemokine regulation and neuroinflammatory response-related pathways to influence the pathological development of MDD. Our results supported the promotion role of AD in the pathological development of MDD, including the regulation of multiple genetic regulators of MDD involved in cytokine/chemokine regulation and inflammatory response.

The Diagnostic Workup in Chronic Spontaneous Urticaria-What to Test and Why

BACKGROUND

In chronic spontaneous urticaria (CSU), the guidelines recommend very limited diagnostic procedures during the routine workup, although additional investigations might be indicated in some patients with CSU. For physicians treating patients with CSU, it is often difficult to decide which diagnostic tests are useful.

OBJECTIVE

To provide recommendations on what diagnostic tests should be performed on which patients with CSU.

METHODS

We performed an extensive literature search on the respective topics and identified relevant questions that should prompt diagnostic procedures based on the published evidence and expert consensus among all authors.

RESULTS

We provide questions, diagnostic testing, where appropriate, and recommendation that should be included when assessing the history of a patient with CSU, to explore and rule out differential diagnoses, to assess patients for underlying causes and modifying conditions, to explore patients for comorbid diseases and consequences of having CSU, and to assess patients for CSU components that can help to predict their disease course and response to treatment.

CONCLUSIONS

Here, we provide physicians treating patients with CSU with information about which clues should lead to which tests and why.

Association of Chronic Spontaneous Urticaria With Anxiety and Depression in Adolescents: A Mediation Analysis

Background: Chronic spontaneous urticaria (CSU) is related to psychiatric comorbidities. It is not clear whether the relationship is affected by modifiable factors. Objectives: To investigate whether the effect of CSU on anxiety and depression in adolescents is mediated by the symptoms of itching and sleep disturbance. Methods: Questionnaire survey was conducted among newly enrolled college students. Dermatologists diagnose skin diseases, including CSU, during health examination. Anxiety and depression were measured by the Generalized Anxiety Disorder Scale and Patient Health Questionnaire, respectively. Sleep quality was measured by the Pittsburgh Sleep Quality Index. The symptoms of itching were measured by the numeric rating scale. According to the hypothesis, the mediating effect model was put forward and the structural equation model is used to build the mediation effect model. The mediation effect model was proposed according to the hypothesis and established using a structural equation model. Results: A total of 2,358 students with no history of systemic disease and no pruritus disease (except CSU) were included in the analysis. A total of 393 CSU patients were included, and 1,965 healthy controls were selected based on age and sex matching. CSU was significantly associated with both anxiety and depression when the symptoms of itching and sleep quality were not modeled. A mediation model was proposed as CSU → itching → sleep disturbance → anxiety or depression. Itching and sleep quality mediated 65.4 and 77.6% of CSU's effects on anxiety and depression, respectively, and CSU had no significant direct effect on anxiety or depression in the mediation models. Conclusions: The associations of CSU with anxiety and depression were mediated by the symptoms of itching and sleep disturbance. Effectively reducing the symptoms of itching thereby could increase natural sleep, which can further treat the emotional disorders among patients with CSU.

Improving of psychological status and inflammatory biomarkers during omalizumab for chronic spontaneous urticaria

Background:

Depression and anxiety are the most common psychiatric comorbidities in chronic spontaneous urticaria (CSU). Omalizumab is a monoclonal antibody approved for CSU treatment. We evaluated the prevalence of anxiety and depression in CSU patients before and after treatment with omalizumab.

Materials & methods:

A total of 30 patients were enrolled in the study: 15 patients affected by CSU and treated with omalizumab and the other 15 healthy subjects did not receive any systemic therapy. All patients were evaluated using Hospital Anxiety and Depression Scale, CRP and erythrocyte sedimentation rate, at baseline and after 6 months.

Results:

The omalizumab group after 6 months of therapy had a decrease of all the scores and biomarkers.

Conclusion:

Omalizumab allowed an improvement of urticaria and mental comorbidities.

Depression and anxiety are the most common psychiatric comorbidities in chronic spontaneous urticaria (CSU). We evaluated the prevalence of anxiety and depression in CSU cases and serum levels of inflammatory biomarkers in CSU patients affected also by psychiatric disorders before and after treatment with omalizumab. Omalizumab induced an improvement of urticaria and concurrent mental comorbidities.

Health-related behaviors and mental health states of South Korean adolescents with atopic dermatitis

Atopic dermatitis (AD) is a common chronic skin disease with a negative influence on adolescent mental health state. We aimed to identify the influencing factors for mental health in adolescents with AD. We used data from the 13th Korean Youth Risk Behavior Web-based Survey (KYRBS) conducted in 2017. KYRBS data were obtained from a stratified, multistage, clustered sample. Participants responded to the question "have you ever been diagnosed with AD by a doctor?" and several yes/no questions about stress, depressive symptoms and suicidal ideation. Among 62 276 participants, the proportion of adolescents with AD was 25.0%. Compared with adolescents without AD, those with AD were significantly more likely to experience stress, depressive symptoms and suicidal ideation (P < 0.001) at rates of 59.1%, 27.8% and 13.9%, respectively. In the multivariate logistic regression model, subjective unhappiness was most strongly associated with stress in subjects with AD (adjusted odds ratio [aOR], 7.34; 95% confidence interval [CI], 5.87-9.18), while depression (aOR, 9.83; 95% CI, 7.85-11.32) and suicidal ideation (aOR, 5.70; 95% CI, 5.01-6.48) were reciprocally the most important risk factors in adolescents with AD. AD in adolescents is associated with a higher prevalence of stress, depressive symptoms and suicidal ideation. It is important for pediatricians to watch for these risks and to screen for suicidality in adolescents with AD.

Effects of Stress on Itch

PURPOSE

Psychological stress and ensuing modulation of the immune and nervous systems can have a significant impact on itch. Stress can exacerbate itch and vice versa, resulting in a vicious cycle that can greatly impair a patient's quality of life. This review summarizes the association between stress and itch, elucidates the mechanism by which these two phenomena influence one another, and explores treatment modalities that aim to reduce stress-induced itch.

METHODS

A complete search of the PubMed and Google Scholar databases was completed and literature pertinent to this review was compiled.

FINDINGS

Both acute and chronic stress can significantly affect itch in healthy individuals and in those diagnosed with itchy skin diseases as well as systemic diseases, thus resulting in a vicious cycle in which stress exacerbates itch and vice versa. The mechanisms by which stress induces or aggravates itch include both central and peripheral activation of the hypothalamic-pituitary-adrenal axis and sympathetic nervous system. Activation of these systems, in turn, affects the mast cells, keratinocytes, and nerves that secrete neuropeptides, such as substance P, nerve growth factor, acetylcholine, histamine, and itchy cytokines. A dysfunctional parasympathetic response is thought to be involved in the chronic stress/itch response. Brain structures associated with emotion, such as the limbic system and periaqueductal gray, which work on the descending facilitation of itch, play a significant role in stress-induced itch.

IMPLICATIONS

As specific brain structures are associated with stress, drug treatments targeting these areas (ie, γ-aminobutyric acid-ergic drugs, serotonin and norepinephrine reuptake inhibitors) may help to modulate itch. Stress can also be combatted using nonpharmacologic treatments such as cognitive-behavioral therapies and stress-relieving holistic approaches (eg, yoga, acupuncture).

A Meta-Analysis of Observational Studies on the Association of Chronic Urticaria With Symptoms of Depression and Anxiety

Background: Chronic urticaria (CU) is a frequently occurring skin condition associated with many psychological factors, but the effect size of associations varied in literature.

Objectives: To perform a systematic review and meta-analysis on the associations of CU with the symptoms of depression and anxiety.

Methods: According to a pre-specified protocol, we systematically searched articles published in PubMed, Web of Science, CNKI, and CQVIP databases between January 2000 and January 2019. Pooled estimates in terms of odds ratios (ORs) or standardized mean differences (SMDs) were calculated according to outcome measures. Subgroup analysis by disease subtypes and tool of measurement, and sensitivity analysis were performed. Risk of bias and quality of studies were evaluated.

Results: Twelve studies were selected for the systematic review. The ORs were 3.99 [95% confidence interval (CI): 3.24–4.91, P < 0.001] for anxiety and 2.94 (95% CI: 2.42–3.58, P < 0.001) for depression. The SMDs of severity were 0.98 for anxiety (95% CI: 0.76–1.200, P < 0.001) and 0.84 for depression (95% CI: 0.59–1.10, P < 0.001). Subgroup analysis by disease subtypes and tool of measurement showed variations in effect size, where chronic spontaneous urticaria showed greater effects on anxiety (OR = 6.62, 95% CI: 3.67–11.95, P < 0.001) and depression (OR = 6.13, 95% CI: 2.31–16.31, P < 0.001). Sensitivity analysis demonstrated consistent results.

Conclusion: CU is associated with higher risks of anxiety and depression.

Patients with chronic urticaria have a higher risk of psychiatric disorders: a population-based study

BACKGROUND

The prevalence of psychiatric comorbidities in patients with chronic urticaria (CU) in a national population is largely unknown.

OBJECTIVES

To investigate the prevalence of psychiatric disorders and psychiatric medication use in patients with CU in Taiwan.

METHODS

Data were sourced from Taiwan's National Health Insurance Research Database for 2011. Patients who had a primary/secondary International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code of 708·1, 708·8 or 708·9 during 2011 with at least two outpatient visits and an antihistamine prescription were identified as CU cases. Patients with CU were classified into three disease severity groups according to their medication types. Psychiatric disorders were identified by patients having three outpatient visits with a primary or secondary diagnosis of a given psychiatric disease. Psychiatric medication use was defined by having at least four outpatient visits with prescriptions for anxiolytics, antidepressants or sleeping pills in 2010 or 2011.

RESULTS

Of the 167 132 patients with CU, 82·5% had mild CU, 17·0% had moderate CU and 0·4% had severe CU. Patients with CU had a higher prevalence of psychiatric disorders and psychiatric medication prescription than control groups. The relative risk (RR) of psychiatric disorders was 1·43 for patients with mild, 1·50 for patients with moderate and 2·32 for patients with severe CU vs. the controls (P < 0·001). For psychiatric medication prescription, the RRs were 1·95, 2·70 and 2·09, respectively, vs. controls (P < 0·001).

CONCLUSIONS

Patients with CU had a higher prevalence and risk of psychiatric disorders and psychiatric medication prescription than control groups. What's already known about this topic? Previous studies have shown a high prevalence of psychiatric comorbidities in patients with chronic urticaria (CU), with rates ranging from 35% to 60%. Anxiety, depression and somatoform disorders have been reported as the most prevalent mental disorders in patients with CU. What does this study add? Patients with CU had a higher prevalence of psychiatric disorders and psychiatric medication use than control groups in the general population. The relative risk (RR) of psychiatric disorders was 1·43 for those with mild CU, 1·50 for those with moderate CU and 2·32 for those with severe CU vs. controls. The RR for psychiatric medication use was 1·95 for those with mild CU, 2·70 for those with moderate CU and 2·09 for those with severe CU vs. controls. Mental health evaluations and management are important elements in CU management.

The vicious cycle of itch and anxiety

Chronic itch is associated with increased stress, anxiety, and other mood disorders. In turn, stress and anxiety exacerbate itch, leading to a vicious cycle that affects patient behavior (scratching) and worsens disease prognosis and quality of life. This cycle persists across chronic itch conditions of different etiologies and even to some extent in healthy individuals, suggesting that the final common pathway for itch processing (the central nervous system) plays a major role in the relationship between itch and anxiety. Pharmacological and nonpharmacological treatments that reduce anxiety have shown promising anti-itch effects. Further research is needed to establish specific central mechanisms of the itch-anxiety cycle and provide new targets for treatment.

Sense of coherence as a protective factor in chronic urticaria

INTRODUCTION

Chronic urticaria (CU) seems to be perceived as a psychodermatological disorder. Different psychological factors play an important role in CU triggering and course. One of them is a sense of coherence (SOC), which is believed to be a protective factor against anxiety and depression.

AIM

To investigate quality of life (QoL) in CU patients and to compare selected psychological parameters (anxiety, depression and sense of coherence) between CU individuals and the control group.

MATERIAL AND METHODS

The study comprised 46 female patients with chronic urticaria and 33 healthy females as a control group. The following methods were employed: Urticaria Activity Score (UAS), Hospital Anxiety and Depression Scale (HADS), Sense of Coherence Questionnaire (SOC-29) and Dermatology Life Quality Index (DLQI).

RESULTS

The CU patients presented a significantly higher anxiety level in comparison to the control group (z = 4.488; p < 0.001). There were no statistically significant differences regarding depression intensity and SOC. In both groups anxiety and depression negatively correlated with global SOC and all its components. Disease severity positively correlated with QoL (ρ = 0.46, p < 0.01) and negatively with global SOC (ρ = -0.33, p < 0.05).

CONCLUSIONS

Bearing in mind higher prevalence of anxiety and depressive symptoms in our CU group, it would be useful to perform screening of these aspects in all CU patients and subsequently develop respective psychological interventions, based on enhancement of personal resources.

Association of atopic dermatitis with depressive symptoms and suicidal behaviors among adolescents in Korea: the 2013 Korean Youth Risk Behavior Survey

BACKGROUND

Atopic dermatitis (AD) is a chronic skin disease which has been known to negatively influence the mental health of patients. However, only a few studies have explored the prevalence of psychiatric problems among AD patients, particularly among adolescents. In this study, we aimed to assess the association of AD with depressive symptoms and suicidal behaviors among adolescents by analyzing data from the 2013 Korean Youth Risk Behavior Survey, a nationwide web-based survey.

METHODS

Data from 72,435 adolescent middle and high school students in Korea were analyzed. Students self-reported AD diagnosed by a doctor and yes-or-no answers to questions about depressive symptoms and suicide ideation, suicide planning, and suicide attempts were analyzed. Relationships between AD and depressive symptoms or suicidal behaviors were tested by logistic regression models after controlling for potential confounding factors.

RESULTS

The proportion of adolescents who had AD was 6.8%. The proportion of adolescents reporting depressive feelings was 31.0%, suicide ideation was 16.3%, suicide planning was 5.8%, and suicide attempts was 4.2%. Compared to adolescents without AD, adolescents with AD were significantly more likely to experience depressive feelings (odds ratio [OR]: 1.27, 95% confidence interval [Cl]: 1.19-1.36), suicide ideation (OR: 1.34, 95% Cl: 1.24-1.45), suicide planning (OR: 1.46, 95% Cl: 1.32-1.65), and suicide attempts (OR: 1.51, 95% Cl: 1.33-1.72). In the multivariate model, the relationships between AD and suicide ideation (OR: 1.26, 95% Cl:1.16-1.36), suicide planning (OR: 1.28, 95% Cl:1.14-1.44), and suicide attempt (OR: 1.29, 95% Cl:1.13-1.49) were statistically significant.

CONCLUSION

Adolescents who have AD are associated with a higher prevalence of depression symptoms and suicidal behaviors. Adolescent AD patients may need interventions from clinicians and caregivers that use a holistic approach to prevent psychological comorbidities, although further research is needed to clarify this relationship.

Temperament and character profiles of patients with chronic idiopathic urticaria

Introduction

Psychosocial factors have been implicated as being important in the onset and/or exacerbation of urticaria.

Aim

To examine both personality factors of patients with chronic idiopathic urticaria (CIU) and the correlations between illness duration, severity of itching, urticaria activity score (UAS) and temperament-character dimensions.

Material and methods

A total number of 70 CIU patients and 60 healthy individuals were included in the study. The Temperament and Character Inventory (TCI) was administered individually. The relationship between UAS, illness duration and severity of pruritus and TCI subscales were evaluated.

Results

The CIU group had significantly higher scores of novelty seeking and lower scores of cooperativeness, reward dependence and self-directedness than the control group.

Conclusions

The current study shows that CIU patients have distinctive temperament and character dimensions when compared with the control group. We suggest that evaluation and treatment of CIU should also include psychosomatic approaches in clinical practice.

Chronic urticaria due to autoreactivity to progesterone

A 23-year-old, regularly menstruating woman presented with recurrent urticarial eruptions, which occurred premenstrually. A skin prick test was positive for progesterone, but the urticaria was unresponsive to standard treatments. The patient was treated with goserelin (Zoladex), which suppressed her menstrual cycle, leading to the resolution of her symptoms. Subsequent flares were controlled by further goserelin injections, and the urticaria is currently in remission. However, the risks of inducing menopause artificially are significant, and alternative long-term solutions may need to be considered in the event of a relapse.

Psychosocial factors and chronic spontaneous urticaria: a systematic review

BACKGROUND

Chronic spontaneous urticaria (CSU) is one of the most costly allergic conditions challenging physicians as well as patients and their families. Despite evident lacunae in the understanding of the pathogenesis, at least some findings suggest that psychosocial factors likely contribute to the development and exacerbation of CSU. We aim to assess the contribution of psychological factors to CSU.

METHODS

Systematic search of PubMed and OVID/Medline databases was conducted from 1 January 1935 to 1 January 2012. Studies selected include original research in English, Spanish and French exploring the association between CSU and psychosocial factors. Two investigators independently reviewed all titles and abstracts to identify potentially relevant articles and resolved discrepancies by repeated review and discussion and arbitration of a third reviewer. Quality of systematic reviews and meta-analyses was assessed using a measure based on the Newcastle-Ottawa Scale and psychological conditions of CSU patients.

RESULTS

We identified 114 eligible studies spanning 77 years and featuring 17 reviews, 67 studies related to neither CSU nor psychosocial factors, and eight studies that provided either no prevalence estimates or insufficient sample size. Pooling effect sizes using random effects, analyses revealed that, despite large heterogeneity (I(2) of 97.60%), psychosocial factors had a prevalence of 46.09% (95% confidence interval, 44.01%, 48.08%).

CONCLUSION

Future research needs to better establish the contribution of psychosocial factors to the pathogenesis and exacerbation of CSU, and explore the possible benefit of behavioural interventions to the development of new management strategies.

[Selected psychosomatic aspects of dermatologic practice]

In recent years, mental disorders and diseases have moved more and more into the focus of public attention and play an increasingly larger role in clinical practice. Dermatologists are familiar with the relationship between psyche and skin, but they not are only confronted with patients whose mental illness afflicts the skin, but also by those with problems of coping with serious and/or stigmatizing skin diseases. Furthermore, there are psychological influences on the course of various dermatologic diseases. The present article provides an overview over the complex interactions between mental and cutaneous disease and presents treatment options.

Specificity in the association of anxiety, depression, and atopic disorders in a community sample of adolescents

The specificity of relationships between anxiety and depressive symptoms, with each of the major atopic disorders of asthma, allergic rhinitis (AR), and atopic dermatitis (AD) was systematically investigated within a single study sample. Participants included 367 adolescents who participated in a community, longitudinal study investigating risk factors for the development of psychiatric and physical health problems. Mental health symptoms were assessed at 7, 9, 11, and 13 years of age. Lifetime history of atopic disorders was assessed by parent report at age 13. Analysis of variance was used to investigate the specificity of the associations between anxiety and depression, and each of the atopic disorders. Results indicated that anxiety was associated with a lifetime history of atopic disorders as a group. The association was significantly strengthened when controlling for depression and externalizing psychiatric symptoms. Among atopic disorders, "pure" anxiety was associated with asthma and AR, and having both asthma and AR strengthened the association compared to having either disorder alone. The association of "pure" anxiety with asthma and AR is consistent with existing data suggesting a relationship between anxiety and respiratory disorders. Having both asthma and AR appeared to confer an additive "dose effect" on the strength of the association. The lack of an association with depression suggests that other factors may contribute to the differential expression of anxiety and depression with atopic disorders. Findings demonstrate the importance of assessing the impact of co-morbid psychiatric symptoms and atopic disorders within individual studies to determine the specificity of underlying relationships between these conditions.

Chronic idiopathic urticaria and anxiety symptoms

Chronic idiopathic urticaria (CIU) is a frequently disabling disease with a negative influence on the quality of life, and can cause psychopathological symptoms, such as anxiety. Our aim is to study further anxiety symptoms on CIU patients. Both CIU patients and the control group were studied by means of validated scales for psychopathology symptoms, psychological variables and quality of life. In this study, we reported high levels of anxiety symptoms. We found statistically significant correlations between anxiety symptoms, some personality dimensions, insecure attachment styles, alexithymia and with some quality of life dimensions. CIU patients exhibit high levels of psychological distress that could potentiate difficulties at several domains, namely social, emotional, general health perception and interpersonal relationships.

Relevance of psychiatry in dermatology: Present concepts

Skin is an organ that has a primary function in tactile receptivity and reacts directly upon emotional stimuli. Dermatological practice involves a psychosomatic dimension. A relationship between psychological factors and skin diseases has long been hypothesized. Psychodermatology addresses the interaction between mind and skin. It is divided into three categories according to the relationship between skin diseases and mental disorders. This article reviews different dermatological conditions under each of the three categories namely psychosomatic disorders, dermatological conditions due to primary and secondary psychiatric disorders. Dermatological conditions resulting from psychiatric conditions like stress/depression and those caused by psychiatric disorders are discussed. This review intends to present the relationship between the 'skin' and the 'mind' specifically from the dermatology point of view. The effects on the quality of life as a result of psychodermatological conditions are highlighted. A multidisciplinary approach for treatment from both dermatologic and psychiatric viewpoints are suggested.

Ekbom syndrome: the challenge of "invisible bug" infestations

Ekbom Syndrome is synonymous with delusory parasitosis, a belief that one's body is infested by invisible bugs. Persons suffering from this syndrome often claim to feel dermal sensations and to visualize the bugs, although no one else can see them. Ekbom Syndrome is a delusional condition; it is intractable and cannot be corrected by argument or evidence. Ekbom Syndrome sufferers exhibit a range of predictable behaviors in their attempts to eliminate their infestations, including seeking identifications and treatment from physicians and entomologists. Frequently they also experience comorbid psychological conditions. Because this is a delusional affliction, successful treatment typically requires neuroleptic medications, necessitating intervention by medical professionals.

The levels of depression, anxiety and quality of life in patients with chronic idiopathic urticaria

BACKGROUND

Chronic idiopathic urticaria (CIU) is associated with severely impaired quality of life (QoL).

OBJECTIVE

To determine the levels of depression, anxiety and QoL in CIU patients.

PATIENTS AND METHODS

This study included 73 patients with CIU, and 34 healthy subjects matched for age and sex were used as controls. The levels of depression, anxiety and QoL were assessed with the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI) and the World Health Organization Quality of Life Assessment-Brief (WHOQOL-BREF), respectively. The reliability and validity of the Turkish versions of these instruments have been examined.

RESULTS

When compared with healthy controls, patients with CIU had significantly higher BDI and BAI scores and significantly lower physical health and psychological health subscale scores of the WHOQOL-BREF. BDI, BAI and all domains of WHOQOL-BREF were unrelated to age, duration of illness, urticaria activity score (UAS) and visual analogue score (VAS). There was a negative significant correlation between all domains of WHOQOL-BREF and BDI and BAI.

CONCLUSION

Our data confirm that QoL is markedly reduced in CIU patients. Physical health and psychological health were found to be the areas QoL most affected in CIU patients. And also we have found that CIU patients frequently suffer from depression and anxiety. The severity of these parameters was found to be positively correlated with the extent of QoL decrease.

Relationship between anger and pruritus perception in patients with chronic idiopathic urticaria and psoriasis

BACKGROUND

There is evidence that chronic idiopathic urticaria (CIU) and psoriasis are associated with personality based difficulties in emotional regulation particularly with regard to the feeling of anger. This deficit in emotional awareness could lead to the phenomenon that emotions are rather experienced in bodily symptoms such as pruritus.

AIM

We investigated whether there is a relationship between pruritus as major symptoms in CIU and psoriasis and the experience of negative emotions.

SETTING

Forty-one CIU patients and 44 psoriasis patients treated at Bonn University Hospital and 49 healthy controls were included.

METHOD

Patients and controls were compared on questionnaires measuring alexithymia (TAS-20), emotional distress (SCL-90-R) and anger (STAXI). In skin-disordered patients, separate stepwise regressions with pruritus severity as dependent variable and questionnaires, skin status, duration, sex and age as independent variables were calculated.

RESULTS

CIU and psoriasis patients showed higher alexithymia, emotional distress, depression, anxiety and state anger compared with controls. State anger was the only significant predictor of pruritus severity in CIU explaining 19% of variance. Depression was the only significant predictor of pruritus severity in psoriasis explaining 12% of variance.

CONCLUSIONS

Our findings suggest a relationship between pruritus severity and anger in CIU. Furthermore, our results indicate a relationship between pruritus severity and depression in psoriasis.

Axis I and Axis II diagnoses in patients with chronic idiopathic urticaria

OBJECTIVE

This study presents the current prevalence of Axis I and Axis II psychiatric diagnoses and factors associated with the existence of Axis I psychiatric disorders in patients with chronic idiopathic urticaria (CIU).

METHOD

The study sample was composed of 89 patients with CIU and 64 control subjects. Axis I and Axis II psychiatric disorders were ascertained by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition and the Structured Clinical Interview for DSM, Revised Third Edition Personality Disorders, respectively.

RESULTS

Of patients with CIU, 44 (49.4%) had at least one Axis I diagnosis, and 40 (44.9%) had at least one personality disorder. The most common Axis I disorder was obsessive-compulsive disorder (25.8%), and the most common Axis II disorder was obsessive-compulsive (30.3%) personality disorder in patients with CIU. Obsessive-compulsive disorder, major depression, obsessive-compulsive and avoidant personality disorders were more prevalent in patient group compared to control group. Obsessive-compulsive and avoidant personality disorders were related to the existence of Axis I disorders in patients with CIU.

CONCLUSION

Psychiatric morbidity seems to be a frequent healthy problem in patients with CIU.

Psychiatric morbidity and quality of life in patients with chronic idiopathic urticaria

BACKGROUND

Chronic idiopathic urticaria (CIU) is a frequently occurring disease that has a great impact on the health-related quality of life (HRQL) of patients and seems to be associated with a number of psychological factors.

OBJECTIVES

To determine the prevalence of psychiatric morbidity in patients with CIU and to determine HRQL of CIU patients compared with controls.

METHODS

A semistructured interview form, a generic form of the HRQL questionnaire (Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]), and the Structured Clinical Interview for DSM-IV Axis Disorders (SCID-I) were administered to CIU patients who presented to the Allergy Department of the University of Istanbul (from January 1 to April 30, 2005). Healthy subjects matched sociodemographically with the study group were used as the control group.

RESULTS

Eighty-four CIU patients and 75 controls were included in the study. The mean +/- SD age of the study participants was 36.83 +/- 10.26 years, and 84% were women. The mean +/- SD duration of the disease was 6.34 +/- 7.2 years, and symptoms were intermittent in 51%. The SCID-I revealed a psychiatric diagnosis in 60% of the patients. In terms of the distribution of psychiatric diagnoses, the most frequently occurring diagnosis was depressive disorders (40%). Most patients (81%) believed that their illnesses were due to stress. The subdomains on the SF-36 measurements were significantly lower than those of the control subjects (P < or = .005). The physical function, vitality, and mental health subdomains of the SF-36 in the patients with a psychiatric diagnosis were significantly lower (P < .05).

CONCLUSION

These findings suggested that psychiatric morbidity is high among ICU patients and is detrimental to their quality of life.

Psychodermatology: a guide to understanding common psychocutaneous disorders

OBJECTIVE

This review focuses on classification and description of and current treatment recommendations for psychocutaneous disorders. Medication side effects of both psychotropic and dermatologic drugs are also considered.

DATA SOURCES

A search of the literature from 1951 to 2004 was performed using the MEDLINE search engine. English-language articles were identified using the following search terms: skin and psyche, psychiatry and dermatology, mind and skin, psychocutaneous, and stress and skin.

DATA SYNTHESIS

The psychotropic agents most frequently used in patients with psychocutaneous disorders are those that target anxiety, depression, and psychosis. Psychiatric side effects of dermatologic drugs can be significant but can occur less frequently than the cutaneous side effects of psychiatric medications. In a majority of patients presenting to dermatologists, effective management of skin conditions requires consideration of associated psychosocial factors. For some dermatologic conditions, there are specific demographic and personality features that commonly associate with disease onset or exacerbation.

CONCLUSIONS

More than just a cosmetic disfigurement, dermatologic disorders are associated with a variety of psychopathologic problems that can affect the patient, his or her family, and society together. Increased understanding of biopsychosocial approaches and liaison among primary care physicians, psychiatrists, and dermatologists could be very useful and highly beneficial.

Psychiatric and psychological co-morbidity in patients with dermatologic disorders: epidemiology and management

Psychiatric and psychological factors play an important role in at least 30% of dermatologic disorders. In many cases the impact of the skin disorder upon the quality of life is a stronger predictor of psychiatric morbidity than the clinical severity of the disorder as per physician ratings. Furthermore, in certain disorders such as acne and psoriasis, the psychiatric co-morbidity, which can be associated with psychiatric emergencies such as suicide, is an important measure of the overall disability experienced by the patient. The severity of depression and increased suicide risk are not always directly correlated with the clinical severity of the dermatologic disorder. Consideration of psychiatric and psychosocial factors is important both for the management, and for some aspects of secondary and tertiary prevention of a wide range of dermatologic disorders. It is useful to use a biopsychosocial model which takes into account the psychological (e.g. psychiatric comorbidity such as major depression and the impact of the skin disorder on the psychological aspects of quality of life) and social (e.g. impact upon social and occupational functioning) factors, in addition to the primary dermatologic factors, in the management of the patient. Some dermatology patients are likely to benefit from psychotherapeutic interventions and psychotropic agents for the management of the psychosocial comorbidity, in addition to the standard dermatologic therapies for their skin disorder.

The relation of psychogenic excoriation with psychiatric disorders: a comparative study

Psychogenic excoriation (PE), characterized by excessive scratching or picking of the skin, is not yet recognized as a symptom of a distinct DSM-IV disorder. It is a chronic disorder with a high rate of psychiatric comorbidity. The purpose of this study was to compare patients diagnosed with PE and patients with another dermatological disease in terms of comorbid psychiatric disorders. Thirty-one consecutive subjects were recruited from an outpatient dermatology clinic. The control group was composed of 31 patients with chronic urticaria. All subjects were interviewed using the Structured Clinical Interview for DSM-III-R (SCID-I), Beck Depression Inventory (BDI), Hamilton Anxiety Rating Scale (HARS), and Yale-Brown Obsession and Compulsion Scale (Y-BOCS) and also completed a semistructured questionnaire. Current major depressive syndrome was the most common psychiatric disorder in the PE group. There was a statistically significant difference between the two groups in terms of current major depressive syndrome (PE group 58.1%, control group 6.5%, P<.01). In the PE group, 45.2% of subjects were diagnosed with obsessive compulsive disorder (OCD), while the rate of OCD was only 3.7% in the control group (P <.01). The PE group scored significantly higher on the BDI, HARS, and Y-BOCS. The results of this study point to the close relationship of PE to depression and OCD.

Psychiatric dysfunction in connective tissue diseases: association with Sjögren's syndrome

Abstract We studied 217 patients with connective tissue disease (CTD), comprising 55 patients with primary Sjögren's syndrome (SS), 34 with secondary SS, and 128 without SS. Psychiatric manifestations were investigated using three questionnaires: the Arthritis Impact Measurement Scale 2 (AIMS2), the Cornell Medical Index (CMI), and the Beck Depression Inventory (BDI). Stratified analysis revealed that the frequency of a neurotic state (levels III + IV in CMI) in both primary SS patients (53%; 29% + 24%) and secondary SS patients (67%; 41% + 26%) was significantly greater than in CTD patients without SS (34%; 20% + 14%) (P < 0.05 and P < 0.001, respectively). The median and Q1-Q3 BDI scores in secondary SS patients (7.5 and 4.0-20.0) were significantly higher than those in CTD patients without SS (5.0 and 1.0-10.0) (P < 0.05). Neither the frequency of a neurotic state nor the BDI score differed significantly between patients with primary SS and those with secondary SS. Regression analysis showed significant correlations between the AIMS2 level-of-tension scale and CMI classifications (rs = 0.676, P < 0.001), and between the AIMS2 mood scale and BDI score (rs = 0.679, P < 0.001). SS should always be borne in mind when patients with sicca syndrome and multifarious psychiatric complaints are examined.

Psychocutaneous disorders

Dermatologic conditions are commonly associated with psychiatric sequella, eg, urticaria, alopecia, psoriasis, or acne. Moreover, the onset and course of dermatologic disorders may be significantly influenced by stress, emotional disturbances, or psychiatric disorder. Compulsions involving the skin, excoriations, or hair pulling (trichotillomania) are the more frequently encountered problems. In some cases, skin conditions are self-induced or reflect signs or symptoms of an underlying psychiatric disorder, including psychosis or obsessive-compulsive disorder. Additionally, skin lesions have been frequently described in case reports of factitious dermatitis. Finally, adverse effects of psychotropic drugs may cause dermatologic side effects, mostly idiosyncratic skin eruptions. These problems are discussed with emphasis on clinical features, comorbidity, and psychiatric management.

Anxiety, depression and psychosomatic symptoms in patients with atopic dermatitis: comparison with normal controls and among groups of different degrees of severity

Atopic dermatitis is a common skin disorder. The age distribution is mainly located from infancy to adolescence, which period is the most important for forming character or effecting their psychological condition. We used three types of psychological tests to investigate anxiety, depression and psychosomatic symptoms in 45 patients with atopic dermatitis and 34 normal controls. These tests consisted of the manifest anxiety scale (MAS), self-rating depression scale (SDS) and Cornell Medical Index (CMI). On the MAS, the atopic dermatitis group did not show any statistical difference from normal controls. However, the SDS and the CMI produced statistically significant differences (P < 0.05 and P < 0.01, respectively). Furthermore, we classified their symptom in three degrees of severity (mild: 15; moderate: 14; severe: 16). Patients with mild symptoms did not show any statistical difference from normal controls on the three tests. Patients with moderate symptoms showed a statistically significant difference from normal controls on the SDS (P < 0.01) and the CMI (P < 0.05), but not on the MAS. Finally, patients with severe symptoms (in-patients) produced somewhat lower test scores than those with moderate symptoms. We conclude that the patients with atopic dermatitis were more depressive and psychosomatic symptom-prone than normal controls, and suggest that some patients with atopic dermatitis should be treated both dermatologically and psychiatrically.

A combination therapy of psychotropic drugs and antihistaminics or antiallergics in patients with chronic urticaria

The efficacy of psychotropic drugs in combination with antihistaminics or antiallergics in patients with chronic urticaria was investigated. Forty patients, who had had urticaria for at least one month and showed insufficient suppression of symptoms for more than one month while being treated with antihistaminics or antiallergics, were divided into two groups on the basis of their score on three kinds of psychological tests: a manifest anxiety test, a self-rating depression scale and the Cornell medical index. One group had a high score, the other a low score. We investigated both groups with or without psychotropics in combination with antihistaminics or antiallergics. Incidence of urticaria and degree of improvement were examined after 2 and 6 months. There was no statistical difference between the groups after 2 months. After 6 months, the members of the low-score group treated with psychotropics showed a little better prognosis than those not treated. However, the high-score group treated with psychotropics showed a statistically significant decrease of incidence and increase in degree of improvement (P < 0.01). In conclusion, it is suggested that a long-term combination therapy with psychotropics is effective in suppressing urticaria for patients who are anxious, depressive and psychosomatic symptom-prone, and moderately effective for those with a low score in these areas.

Psychosomatic treatment of a case of chronic urticaria

A 35-year-old Japanese woman presented with urticaria in January of 1992. As her symptoms gradually became worse, she came to our hospital in March of that year. I treated her with various combinations of antihistaminics and antiallergics. However, her symptoms did not respond and continued to deteriorate. Although her blood was analyzed in an attempt to identify antigenic or physical factors, no positive data were obtained. Because three kinds of psychological tests showed that the patient was highly anxious and depressive, I additionally treated her with psychotropics and psychotherapy in May of 1994. After a month, the symptoms began to disappear. She has since been free from the symptoms while taking medicine only twice a week. Our group recently presented the efficacy of psychotropics in patients with chronic urticaria. This case suggests that highly anxious or depressive cases with chronic urticaria should be treated not only dermatologically, but also psychologically.
