Factors Associated with Affective Symptoms and Quality of Life in Patients with Atopic Dermatitis

Facets of shame and their impact on quality of life in patients with atopic dermatitis and psoriasis

Shame is a complex emotion with different facets. Skin shame is a specific aspect of body shame, which involves the skin perceived as inferior or flawed. Its role in atopic dermatitis (AD) and psoriasis is not well investigated. This explorative study pursued three objectives: First, the comparative analysis of shame and its facets in AD and psoriasis. Second, analysis of the association of skin shame with other shame facets, depression, and anxiety. Third, exploration of the unique impact of shame and its different facets on quality of life (QoL) in AD and psoriasis patients. This cross-sectional online survey encompassing German-speaking patients included several self-report measures on skin and general shame, depression, and anxiety as well as the Dermatology Life Quality Index (DLQI), Patient-Oriented Eczema Measure (POEM), and Psoriasis Symptoms and Signs Diary (PSSD). Data from 413 adult participants with AD (N = 162) or psoriasis (N = 251) were analyzed. There were no significant differences in skin or general shame, depression, or anxiety between those with AD or psoriasis. Skin shame as well as other aspects of shame were associated with younger age, female sex, depression, anxiety, and QoL. Analysis of AD and psoriasis subsamples revealed significant correlations of disease severity with skin shame, depression, anxiety, and DLQI. Hierarchical linear regression analyses indicated that skin shame was the second most important determinant of QoL after self-assessed disease severity. Systematic consideration of shame in AD and psoriasis is necessary in order to effectively reduce disease burden and enhance QoL.

Impact on Major Life-changing Decisions in Patients with Atopic Dermatitis

Atopic dermatitis (AD) is a chronic skin disease that significantly affects patients' quality of life. While other dermatological conditions like psoriasis are known to impact major life-changing decisions (MLCD), no prior studies have evaluated this in AD. A descriptive cross-sectional study was conducted in patients with AD of at least 6 months' duration. Sociodemographic and clinical characteristics of the patients, as well as severity from both the physician's and patient's point of view, were assessed using different rating scales such as the Eczema Area and Severity Index (EASI). Subsequently, patients were divided according to disease severity into severe AD (EASI ≥ 21) or mild-moderate AD (EASI < 21). Life decisions were evaluated across several areas, including work, education, social life, reproduction, recreation, housing, and lifestyle, using a 4-point Likert scale. A total of 104 patients, with an average disease duration of 20.36 years, were included. The results showed significant MLCD impairment, especially in clothing choices (52.9%), lifestyle (48.1%), and sports activities (41.4%). Severe AD was associated with greater social and emotional challenges, such as difficulties in social interactions (48.6% vs 26.1%) and romantic relationships (48.5% vs 18.8%) compared with mild-moderate AD. These findings highlight the profound impact of AD on daily life, emphasizing the need for comprehensive management strategies that address physical, psychological, and social aspects.

The APOLO Study: A Cross-Sectional Analysis of Disease Characteristics and Patient Burden in Moderate-to-Severe Atopic Dermatitis in Portugal

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a substantial impact on patients' quality of life (QoL). This study aimed to characterize the burden of moderate-to-severe AD in the Portuguese population, focusing on patients' QoL and socioeconomic activities while describing their treatment patterns and healthcare resource use.

METHODS

This multicenter, cross-sectional, and non-interventional study in eight Portuguese referral AD centers recruited patients over 12 years old, seeking first-time AD care. Patients over 16 years old were analyzed, and data on demographics, clinical characteristics, treatment patterns, healthcare resource utilization, and burden of disease via patient-reported outcomes (PROs) were collected.

RESULTS

With a predominantly White cohort, a mean age of 30.0 years, and balanced gender distribution, the study highlighted the significant impact of moderate-to-severe AD on patients' QoL, with a mean Dermatology Life Quality Index score of 15.19. High levels of itch, lesional skin severity, sleep disturbance, and pain contributed to the substantial burden of disease. Productivity was impaired in 40.0% of patients and daily activities were disrupted in 50.0%. Average body surface area involvement was 45.82%, with a mean of 6.49 AD flares in the previous year. Dermatologists played a pivotal role in the patient journey, contributing significantly to the diagnosis (55.9%) and referral process (70.9%). Treatment patterns highlighted a historical reliance on topical therapies and an evolving landscape with post-visit inclusion of advanced therapies such as dupilumab (38.5%), conventional immunosuppressants like cyclosporine (31.2%), and baricitinib (6.8%).

CONCLUSION

This study unveils the intricate landscape of moderate-to-severe AD in Portugal, highlighting a substantial unmet need for optimal disease management. The role of dermatologists is crucial, yet limited adoption of advanced therapies in the face of significant disease burden prompts critical reflection.

Atopic dermatitis: pathogenesis and therapeutic intervention

The skin serves as the first protective barrier for nonspecific immunity and encompasses a vast network of skin-associated immune cells. Atopic dermatitis (AD) is a prevalent inflammatory skin disease that affects individuals of all ages and races, with a complex pathogenesis intricately linked to genetic, environmental factors, skin barrier dysfunction as well as immune dysfunction. Individuals diagnosed with AD frequently exhibit genetic predispositions, characterized by mutations that impact the structural integrity of the skin barrier. This barrier dysfunction leads to the release of alarmins, activating the type 2 immune pathway and recruiting various immune cells to the skin, where they coordinate cutaneous immune responses. In this review, we summarize experimental models of AD and provide an overview of its pathogenesis and the therapeutic interventions. We focus on elucidating the intricate interplay between the immune system of the skin and the complex regulatory mechanisms, as well as commonly used treatments for AD, aiming to systematically understand the cellular and molecular crosstalk in AD-affected skin. Our overarching objective is to provide novel insights and inform potential clinical interventions to reduce the incidence and impact of AD.

Baricitinib as monotherapy and with topical corticosteroids in moderate-to-severe atopic dermatitis: a systematic review and meta-analysis of dose-response

Introduction

Atopic dermatitis (AD) is a chronic inflammatory skin disorder that affects millions worldwide, presenting challenges in managing symptoms and quality of life. Current treatments include topical corticosteroids (TCS), but novel approaches, such as Janus kinase (JAK) inhibitors, show promise. Baricitinib, a selective JAK1 and JAK2 inhibitor, targets cytokines involved in AD and offers potential benefits beyond traditional therapies.

Methods

A systematic review and meta-analysis of randomized controlled trials (RCTs) was performed to evaluate the efficacy and safety of baricitinib in treating moderate-to-severe AD. We followed PRISMA guidelines and assessed data from PubMed, Cochrane Central, ScienceDirect, and ClinicalTrials.gov up to August 2024. The analysis included trials comparing baricitinib to placebo, with or without TCS, evaluating outcomes such as Investigator's Global Assessment (IGA) scores, Eczema Area and Severity Index (EASI) scores, and safety profiles.

Results

Six RCTs involving 2,595 participants met the inclusion criteria. Baricitinib demonstrated significant improvements in IGA scores, EASI scores, Dermatology Life Quality Index (DLQI), and other outcome measures compared to placebo. The efficacy was consistent across different dosages (1 mg, 2 mg, 4 mg) and whether baricitinib was used with or without TCS. Safety analyses revealed a significant increase in treatment-emergent adverse events (TEAEs), particularly with the 2 mg and 4 mg dosages and with TCS.

Conclusion

Baricitinib, both alone and in combination with TCS, significantly improves symptoms and quality of life in patients with moderate-to-severe AD, with efficacy consistent across dosages. The safety profile is overall acceptable, though a significant increase in TEAEs was observed, particularly with higher dosages and when used with TCS. Ongoing monitoring of TEAEs is recommended, and future trials with longer follow-up periods are suggested to better understand long-term outcomes.

A Systematic Review of 207 Studies Describing Validation Aspects of the Dermatology Life Quality Index

This study systematically analysed peer-reviewed publications describing validation aspects of the Dermatology Life Quality Index (DLQI) and used Naicker's Critically Appraising for Antiracism Tool to assess risk of racial bias. Seven online databases were searched from 1994 until 2022 for articles containing DLQI validation data. Methodology followed PRISMA guidelines, the protocol was registered in PROSPERO, and articles reviewed independently by two assessors. Of 1,717 screened publications, 207 articles including 58,828 patients from >  49 different countries and 41 diseases met the inclusion criteria. The DLQI demonstrated strong test-retest reliability; 43 studies confirmed good internal consistency. Twelve studies were performed using anchors to assess change responsiveness with effect sizes from small to large, giving confidence that the DLQI responds appropriately to change. Forty-two studies tested known-groups validity, providing confidence in construct and use of the DLQI over many parameters, including disease severity, anxiety, depression, stigma, scarring, well-being, sexual function, disease location and duration. DLQI correlation was demonstrated with 119 Patient Reported Outcomes/Quality of Life measures in 207 studies. Only 15% of studies explicitly recruited minority ethnic participants; 3.9% stratified results by race/ethnicity. This review summarizes knowledge concerning DLQI validation, confirms many strengths of the DLQI and identifies areas for further validation.

Clinical Factors and Biomarkers Associated with Depressive Disorders in Older Patients Affected by Chronic Kidney Disease (CKD): Does the Advanced Glycation End Products (AGEs)/RAGE (Receptor for AGEs) System Play Any Role?

Depressive disorders are highly prevalent among subjects suffering from chronic kidney disease (CKD). The aim of the present study is to evaluate clinical and biochemical factors associated with depressive disorders in a sample of older CKD patients, with a focus on advanced glycation end products (AGEs) and their soluble receptors (sRAGEs). A total of 115 older subjects affected by CKD (stages 3 to 5, not in dialysis) were selected for this study. These patients were divided into two groups according to the presence of depressive disorders defined by a score ≥ 10 on the 30-item Geriatric Depression Scale (GDS). The two groups were compared by independent sample t tests for continuous variables and χ2 tests for qualitative ones. Significant variables at univariate analyses were then inserted as predictors of a binary logistic regression model, with the presence or absence of depressive disorders as a dependent variable. The binary logistic regression model showed that patients with concomitant depressive disorders were more frequently of female gender (p < 0.01) and had lower MCP1 (p < 0.01) and AGE circulating levels (p < 0.01) than their counterparts. Depressive disorders in older CKD patients are more prevalent in women and seem to be inversely associated with systemic inflammation and circulating AGEs.

Mental health in patients affected by atopic dermatitis: which effects of treatment with dupilumab?

Atopic dermatitis (AD) is an inflammatory skin disease. Patients with AD are prone to develop anxiety and mood disorders. Aim of this study is to investigate if treatment with dupilumab may improve mental health status of patients affected by AD. A total of 66 patients with severe AD were included: 24 subjects were candidate or have just started (one month) treatment with dupilumab, and 42 have been in treatment for one year. 25.8%, 30.3%, and 45.5% of the total sample showed, respectively, clinically significant anxiety, depression, and symptoms of Internet addiction. Patients with anxiety symptoms resulted to have more severe AD, more sleep problems ( P  = 0.028), less quality of life ( P  = 0.001), more severe depressive symptoms ( P  < 0.001), to be more frequently women ( P  = 0.016), to be less frequently treated with dupilumab for one year ( P  = 0.025). Similarly, patients with clinically significant depressive symptoms resulted to have more severe AD, more sleep problems ( P  = 0.003), less quality of life ( P  < 0.001), more severe anxiety symptoms ( P  < 0.001), to be less frequently treated with dupilumab for one year ( P  = 0.008). Patients with AD treated for one year with dupilumab showed a better mental health profile in terms of less severe anxiety and depression with respect to their counterparts.

Pruritus and Pain Constitute the Main Negative Impact of Atopic Dermatitis® From the Patient's Perspective: A Systematic Review

Atopic Dermatitis® (AD) is an inflammatory skin disease characterized by intense itching and highly visible signs, representing a great burden to the patient. Despite its straightforward diagnosis, AD severity and burden can be underestimated in routine clinical practice. This review aims to determine the impact of AD on patients' lives, establish which domains of life are most affected, and identify symptom drivers of AD burden. A systematic literature review was conducted in Pubmed/Medline, Web of Science, and Scopus following Cochrane and PRISMA recommendations. Observational studies published in English or Spanish between January 1, 2018, and August 31, 2022, evaluating the impact of AD and its symptoms from the patient's perspective, were included. Reviewed studies were assessed for quality following the STrengthening the Reporting of OBservational studies in Epidemiology Checklist. A total of 28 observational studies evaluating the impact of AD and its symptoms from the patient's perspective were included in the review. All domains of the AD patient's life were found to be greatly affected, including health-related quality of life (HRQoL), emotional health, sleep disorders, work impairment, health care resource utilization, cognitive function, and development of comorbidities. The more severe the disease, the greater the impact, worsening in patients with moderate and severe AD. Pruritus and pain are reported to be the disease symptoms with the greatest impact. In conclusion, AD impacts several domains of patients' lives, especially HRQoL and mental health. Pruritus and pain are identified as the main drivers of AD impact, suggesting that optimal symptom control may reduce the burden and improve disease management.

Atopic dermatitis: Pathophysiology, microbiota, and metabolome - A comprehensive review

Atopic dermatitis (AD) is a prevalent inflammatory skin condition that commonly occurs in children. Genetics, environment, and defects in the skin barrier are only a few of the factors that influence how the disease develops. As human microbiota research has advanced, more scientific evidence has shown the critical involvement of the gut and skin bacteria in the pathogenesis of atopic dermatitis. Microbiome dysbiosis, defined by changed diversity and composition, as well as the development of pathobionts, has been identified as a potential cause for recurring episodes of atopic dermatitis. Gut dysbiosis causes "leaky gut syndrome" by disrupting the epithelial lining of the gut, which allows bacteria and other endotoxins to enter the bloodstream and cause inflammation. The same is true for the disruption of cutaneous homeostasis caused by skin dysbiosis, which enables bacteria and other pathogens to reach deeper skin layers or even systemic circulation, resulting in inflammation. Furthermore, it is now recognized that the gut and skin microbiota releases both beneficial and toxic metabolites. Here, this review covers a range of topics related to AD, including its pathophysiology, the microbiota-AD connection, commonly used treatments, and the significance of metabolomics in AD prevention, treatment, and management, recognizing its potential in providing valuable insights into the disease.

Which Factors Are Associated with Persistence of Depressive and Anxiety Symptoms in Patients Affected by Atopic Dermatitis despite 2-Year Treatment with Dupilumab?

Background: Atopic Dermatitis (AD) is a prevalent inflammatory skin disease whose course is often complicated by the presence of concomitant anxiety and depressive disorders. Dupilumab has been demonstrated to be largely effective in AD. The aims of the present study were to (1) to verify the effectiveness of 2-year dupilumab treatment on the depressive and anxiety symptoms of patients affected by AD and (2) to identify predictors of the persistence of psychiatric symptoms despite maintenance treatment with dupilumab. Methods: A total of 331 patients with severe AD were assessed at baseline and at different times over 2 years by a large set of rating scales, including the Eczema Area and Severity Index (EASI), the Hospital Anxiety and Depression Scale (HADS), and the Dermatology Life Quality Index (DLQI). Paired sample t-tests were performed to verify the effectiveness of dupilumab on the severity of AD and mental health items. Two binary logistic regression models were then used to identify the predictors of the persistence of clinically significant depression and anxiety, defined by a score ≥ 8 on each sub-scale of the HADS. Results: After 2 years of treatment with dupilumab, the patients benefited, showing a significant improvement in both the dermatological disease and comorbid depression/anxiety (p < 0.001 for all scales). Overall, 17.5% and 13% of patients, respectively, reported residual depressive and anxiety symptoms after the 2-year treatment with dupilumab. The baseline predictors of the persistence of clinically significant depressive symptoms after the 2-year treatment with dupilumab were found to be a higher body mass index (BMI) (p = 0.012), a lower impact of dermatological disease on quality of life (p = 0.015), and more severe depressive symptoms (p < 0.01), while for anxiety, the only predictor was found to be female gender (p = 0.03). Conclusions: Using a multidisciplinary approach, at baseline, dermatologists should more closely monitor patients who are at a greater risk of maintaining residual psychiatric symptoms despite therapy, such as those with more severe depressive symptoms and those who are overweight.

Burden of Disease in the Real-Life Setting of Patients with Atopic Dermatitis: Italian Data From the MEASURE-AD Study

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory skin disease that negatively impacts the quality of life and work productivity of patients.

OBJECTIVES

We sought to evaluate the real-world burden of AD patients in Italy.

METHODS

This sub-analysis of the MEASURE-AD multicountry study conducted between December 2019-2020 included patients diagnosed with moderate-to-severe AD eligible for or receiving systemic therapy in the previous 6 months. During a single visit, physician and patient-reported questionnaires were used.

RESULTS

A total of 118 adult patients were enrolled and 57.6% (N = 68) of patients had moderate-to-severe AD at the time of enrolment according to the Eczema Area and Severity Index. Sleep disorders interfered with daily function in the previous week in 58.5% (N = 69) of patients, pruritus was severe in 50% (N = 59) and 42.4% (N = 50) reported a flare lasting >7 days in the previous 6 months. According to the Dermatology Quality of Life Index, 37.3% (N = 44) of patients reported a severe impact of AD and approximately 10% had clinical depression/anxiety. Current drug therapy was considered inadequate in controlling AD in 26.3% (N=31) of patients. Work activity impairment was 38.6±31.7% and monthly AD-related expenses were 148.6±134.6 Euros per patient.

CONCLUSIONS

This real-life study documents a high burden of disease in patients with moderate-severe AD in Italy.

Asthma improvement in patients treated with dupilumab for severe atopic dermatitis

Introduction

Atopic dermatitis (AD) is considered a systemic type 2 immune driven disease, and it is associated to many atopic comorbidities including asthma. The aim of our study was to prospectively evaluate the respiratory outcomes in patients with persistent allergic asthma treated with dupilumab due to severe AD (sAD).

Methods

We enrolled eligible patients with sAD for dupilumab treatment from September 2018 to December 2020. We then selected the subgroup of patients sensitized to perennial allergens. Dupilumab's efficacy and safety on AD and comorbid asthma were assessed at baseline, one month, four months, and then every 4 months up to one year.

Results

A total of 437 patients with sAD were enrolled for dupilumab treatment due to sAD, and 273 reached 48 weeks of therapy. Respiratory outcomes were evaluated in the 85 asthmatic patients with positivity only to perennial allergens. Our patients showed statistically and clinically significant improvement in asthma control (Asthma Control Test and Asthma Control Questionnaire) and airway obstruction parameters (FEV1), in addition to the expected AD-related skin outcomes. Specifically, a significant improvement was achieved at the fourth month of dupilumab therapy, and this trend was maintained up to twelve months, regardless of asthma severity.

Conclusions

Our results showed the overall improvement of the clinical picture that dupilumab offers for patients with severe AD and persistent allergic asthma of any severity, highlighting the importance of a global multidisciplinary approach of type 2 driven disease.

Quality of life in children with skin disease: A Spanish sample

INTRODUCTION

The impact of skin diseases on quality of life varies widely, and some can have an impact similar to that of asthma or cystic fibrosis.

MATERIAL AND METHODS

We conducted a cross-sectional, observational and descriptive study with the aim of describing the degree to which quality of life was affected in paediatric patients managed in a dermatology clinic by means of the Children's Dermatology Life Quality Index (CDLQI).

RESULTS

In our study, the skin disease with the greatest impact on quality of life was atopic dermatitis, chiefly on account of symptoms like pruritus and insomnia. It was followed by acne, mainly due to the associated negative feelings (shame, sadness, etc.). Quality of life in patients with viral warts and molluscum contagiosum was mostly affected by the treatment, chiefly based on cryotherapy. Most patients with nevi or café-au-lait spots did not have a decreased quality of life, although up to one third of them had negative feelings in relation to their skin disease.

DISCUSSION

Atopic dermatitis was the common skin disease that caused the greatest impairment in quality of life in our sample, although other diseases also had an impact on different dimensions of quality of life. We ought to underscore the recommendation to use less painful treatments than cryotherapy for viral warts and molluscum contagiosum, as the impairment in quality of life in paediatric patients with these conditions was mainly due to the treatment.

Depressive and Anxiety Disorders in Patients with Inflammatory Bowel Diseases: Are There Any Gender Differences?

Gender differences were identified in the frequency and clinical presentations of inflammatory bowel disease (IBD) and depressive and anxiety disorders, which are more common in IBD patients than in the general population. The present manuscript provides a critical overview of gender differences in the frequency and clinical course of mood and anxiety disorders in IBD patients, with the aim of helping clinicians provide individualized management for patients. All of the included studies found that IBD patients reported a higher frequency of depressive and anxiety disorders than the general population. These findings should encourage healthcare providers to employ validated tools to monitor the mental health of their IBD patients, such as the Patient Health Questionnaire (PHQ-9). In addition, most studies confirm that women with IBD are more likely than men to develop affective disorders and show that up to 65% of women with IBD have depressive and anxiety disorders. Women with IBD require close mental health monitoring and ultimately a multidisciplinary approach involving mental health professionals. Drug treatment in women should be individualized and medications that may affect mental health (e.g., corticosteroids) should be thoroughly reconsidered. Further data are needed to ensure individualized treatment for IBD patients in a framework of precision medicine.

Clinical Markers of Panic and Generalized Anxiety Disorder: Overlapping Symptoms, Different Course and Outcome

Generalized Anxiety Disorder (GAD) and Panic Disorder (PD) share underlying neurobiological mechanisms and several clinical features which, with medical comorbidities, may increase misdiagnosis and delay proper treatment. The aim of the study was to evaluate the association between clinical/socio-demographic markers and GAD/PD diagnosis. Outpatients (N = 290) with PD or GAD were identified in mental health services in Monza and Milan (Italy). Descriptive analyses and a binary logistic regression model were performed. Post-onset psychiatric (p = 0.05) and medical (p = 0.02) multiple co-morbidities were associated with GAD; treatment with selective serotonin reuptake inhibitors (SSRIs) was associated with PD, while GAD diagnosis was associated with treatment with atypical antipsychotics or GABAergic drugs (p = 0.03), as well as psychodynamic psychotherapy (p < 0.01). Discontinuation of the last pharmacological treatment was associated with GAD diagnosis rather than the PD one (p = 0.02). GAD patients may have a worse prognosis than PD patients because of more frequent multiple co-morbidities, relapses and poorer treatment compliance. The different treatment approaches were consistent with the available literature, while the association between GAD and psychodynamic psychotherapy is an original finding of our study. Further studies on larger samples are necessary to better characterize clinical factors associated with GAD or PD.

Dictamnine ameliorates chronic itch in DNFB-induced atopic dermatitis mice via inhibiting MrgprA3

Chronic itch is the most prominent feature of atopic dermatitis (AD), and antihistamine treatment is often less effective in reducing clinical pruritus severity in AD. Multiple studies have shown that histamine-independent itch pathway is thought to predominate in AD-induced chronic itch. Mas-related G-protein-coupled receptor (Mrgpr) A3⁺ sensory neurons have been identified as one of the major itch-sensing neuron populations, and transient receptor potential (TRP) channel A1 is the key downstream of MrgprA3-mediated histamine-independent itch. MrgprA3-TRPA1 signal pathway is necessary for the development of chronic itch and may be the potentially promising target of chronic itch in AD. Dictamnine is one of the main quinoline alkaloid components of Cortex Dictamni (a traditional Chinese medicine widely used in clinical treatment of skin diseases). However, the anti-inflammatory and anti-pruritic effect of dictamnine on AD have not been reported. In this study, we used the 2,4-dinitrofluorobenzene (DNFB)-induced AD mouse model to observe the scratching behavior, inflammatory manifestations, and to detect the expression of MrgprA3 and TRPA1 in skin and DRG. The data demonstrated that dictamnine effectively inhibited AD-induced chronic itch, inflammation symptoms, epidermal thickening, inflammatory cell infiltration, and downregulated the expression of MrgprA3 and TRPA1. Furthermore, dictamnine restrained the excitability of MrgprA3⁺ and TRPA1⁺ neurons. Molecular docking also indicated that dictamnine has better binding affinity with MrgprA3. These results suggest that dictamnine may inhibit chronic itch caused by AD through the MrgprA3-TRPA1 mediated histamine-independent itch pathway, and may have a potential utility in AD treatment.

Women's quality of sleep and in vitro fertilization success

Women undergoing in vitro fertilization (IVF) are emotionally challenged. Anxiety, depression, and sleep disturbances are common complaints. The impact of these symptoms on IVF outcome is however debated. In this study, we aimed at investigating whether sleep quality and psychological health can affect the chances of success of the procedure. Women undergoing IVF were recruited at the time of oocytes retrieval. Women's sleep quality and psychological health was assessed using the Pittsburgh Sleep Quality Index (PSQI), the Fertility Problem Inventory (FPI), and the Hospital Anxiety and Depression Scale (HADS). Baseline characteristics and results of the three scales were compared between women who did and did not succeed. Overall, 263 women were included, of whom 81 had a clinical pregnancy (31%). As expected, successful women were younger, and their ovarian reserve was more preserved. FPI and HADS scores did not differ. Conversely, a statistically significant difference emerged for the PSQI score, the median [interquartile range] in pregnant and non-pregnant women being 4 [3-5] and 5 [3-7], respectively (p = 0.004). The crude and adjusted OR of pregnancy in women with a PSQI > 5 (indicating impaired sleep quality) was 0.46 (95% CI 0.25-0.86, p = 0.02) and 0.50 (95% CI: 0.26-0.94, p = 0.03), respectively. In conclusion, low sleep quality is common in women scheduled for IVF and could influence the success of the procedure.

Psychologic interventions in patients with the chronic dermatologic itch in atopic dermatitis and psoriasis: A step forward with family constellations seminars

Chronic itch is a complex psychophysiological sensation, which can severely affect the quality of life in patients with atopic dermatitis and psoriasis. Itch depends on the irritation of receptors in the skin and the processing of sensory information in the central nervous system. Severe itch leads to activation and later on to disruption of the stress response, resulting in disorders of skin repair, functional and microstructural changes in the areas of the central nervous system that are responsible for the perception of itch. Psychosocial stress can be an essential factor, activating neurohumoral mechanisms which lead to increased itch and scratch, exacerbating skin damage. Patients with chronic itch often have sleep disorders, increased irritability, and depletion of the nervous system. They are characterized by disrupting social relationships, high incidence of anxiety, depressive disorders, and suicidal tendencies. Psychological methods of intervention can effectively influence various mechanisms in the pathogenesis of itch and scratch and improve social functioning in patients with chronic dermatological itch. In this mini-review, we discuss family constellation seminars as an effective method of psychological intervention that can reduce the intensity of itch, and improve sleep and performance in patients with atopic dermatitis and psoriasis. This method is insufficiently described in previous reviews of psychological interventions in atopic dermatitis and psoriasis patients. The positive impact of family constellations seminars in patients with chronic dermatological itch may be related to reducing stress by improving understanding of the family situation, appropriate management of family secrets, and enhancing interactions with the social environment.

An Overview of the Latest Metabolomics Studies on Atopic Eczema with New Directions for Study

Atopic eczema (AE) is an inflammatory skin disorder affecting approximately 20% of children worldwide and early onset can lead to asthma and allergies. Currently, the mechanisms of the disease are not fully understood. Metabolomics, the analysis of small molecules in the skin produced by the host and microbes, opens a window to observe the mechanisms of the disease which then may lead to new drug targets for AE treatment. Here, we review the latest advances in AE metabolomics, highlighting both the lipid and non-lipid molecules, along with reviewing the metabolites currently known to reside in the skin.

Clinical Characteristics of Atopic Dermatitis in Korean School-Aged Children and Adolescents According to Onset Age and Severity

BACKGROUND

Atopic dermatitis (AD) is a heterogeneous disease with different age of onset, disease course, clinical symptoms, severity, and risk of comorbidity. The characteristics of children with AD also vary by age or country. However, little is known about the clinical characteristics of AD in Korean school-aged children and adolescents. Furthermore, there are few studies on phenotypic differences according to onset age. This study aimed to explore the clinical characteristics and phenotypes according to onset age and severity of AD in children and adolescents in Korea.

METHODS

AD patients aged 6-18 years who presented to 18 hospitals nationwide were surveyed. The patients were examined for disease severity by pediatric allergy specialists, and data on history of other allergic diseases, familial allergy history, onset age, trigger factors, lesion sites, treatment history and quality of life were collected. The results of the patient's allergy test were also analyzed. The patients were classified into infancy-onset (< 2 years of age), preschool-onset (2-5 years of age), and childhood-onset (≥ 6 years of age) groups. Study population was analyzed for clinical features according to onset-age groups and severity groups.

RESULTS

A total of 258 patients with a mean age of 10.62 ± 3.18 years were included in the study. Infancy-onset group accounted for about 60% of all patients and presented significantly more other allergic diseases, such as allergic rhinitis and asthma (P = 0.002 and P = 0.001, respectively). Food allergy symptoms and diagnoses were highly relevant to both earlier onset and more severe group. Inhalant allergen sensitization was significantly associated with both infancy-onset group and severe group (P = 0.012 and P = 0.024, respectively). A family history of food allergies was significantly associated with infancy-onset group (P = 0.036). Severe group was significantly associated with a family history of AD, especially a paternal history of AD (P = 0.048 and P = 0.004, respectively). Facial (periorbital, ear, and cheek) lesions, periauricular fissures, hand/foot eczema, and xerosis were associated with infancy-onset group. The earlier the onset of AD, the poorer the quality of life (P = 0.038). Systemic immunosuppressants were used in only 9.6% of the patients in the severe group.

CONCLUSION

This study analyzed the clinical features of AD in Korean children and adolescents through a multicenter nationwide study and demonstrated the phenotypic differences according to onset age and severity. Considering the findings that the early-onset group is more severe and accompanied by more systemic allergic diseases, early management should be emphasized in young children and infants.
