Anxiety, depression, and stress in Korean patients with chronic urticaria

Quality of life measurement in urticaria: Position statement of the European Academy of Dermatology and Venereology Task Forces on Quality of Life and Patient-Oriented Outcomes and Urticaria and Angioedema

The European Academy of Dermatology and Venereology (EADV) Task Forces on quality of life (QoL) and patient-oriented outcomes and on urticaria and angioedema recommendations for the assessment of Health-related (HR) QoL in all patients with urticaria in research and practice are as follows: to use the DLQI for adults and the CDLQI for children as dermatology-specific and the CU-Q2oL as a disease-specific HRQoL instruments in urticaria; to use generic instruments to provide comparison of data on urticaria with non-dermatologic diseases, or to compare with healthy volunteers or the general population; to select validated HRQoL instruments with appropriate age limits; to present exact numeric data for HRQoL results; correct title of any HRQoL instrument should be used, along with its correct abbreviation and the reference to its original publication, where possible. The EADV TFs discourage the use of non-validated HRQoL instruments and modified HRQoL instruments that have not undergone standard validation.

Vaccine hesitancy in patients presenting to a specialized allergy center: clinical relevant sensitizations, impact on mental health and vaccination rates

Introduction

The COVID vaccination program with new types of vaccinations and early reports of allergic reactions to vaccines led to vaccination hesitancy in patients with allergies. In this study, we aimed to characterize patients who present at an allergy center with specific questions regarding risk assessment to COVID vaccines in comparison to regular allergy center patients.

Methods

A total of 50 patient charts of patients with risk assessment for COVID vaccination (COV group) and 50 regular allergy center patients (ALL group) were assessed for documented allergies, comorbidities, total IgE, and tryptase levels and hospital anxiety and depression score (HADS). Skin prick testing (SPT) with additives of COVID vaccines [polyethylene glycol (PEG), polysorbate] were performed if indicated based on medical history.

Results

Patients who presented for examination prior to a possible COVID vaccination were mostly female (86%) and had more frequently reported allergic reactions to drugs in the past, but only in a minor group (28%) were the reactions qualified as anaphylaxis. The group COV patients scored significantly higher in the HADS for anxiety and depression than the regular group ALL patients. The same trend was observed when data were corrected for gender. It is worth noting that patients without any prior contact to COVID vaccines scored comparable regarding anxiety to patients with prior reaction to COVID vaccinations, but significantly higher in the depression score. In 19 patients (38%) who met the indications for SPT for the suspicious contents PEG and Polysorbate 80, the tests did not show a positive result. Furthermore, 84% of patients underwent the prick test, but only 15% of patients who received consultation alone agreed to vaccination at our center. No vaccination-related event was documented in these patients.

Discussion

In conclusion, vaccination hesitancy was frequently elicited by negative experiences with drugs and putative drug allergies. Female patients predominate in this patient group, and the anxiety and depression scores were significantly elevated. Allergological workup, including SPT, led to a high rate of subsequent vaccinations, whereas a discussion with the patients about risks and individualized advice for vaccination without testing only rarely resulted in documented vaccinations.

Does chronic urticaria affect quality of sleep and quality of life?

Background

Urticaria affects a wide range of daily activities and social relationships. It has a severe impact on quality of life (QOL) and causes psychological problems.

Objective

was to assess the impact of chronic urticaria (CU) on quality of sleep, the levels of depression, anxiety, QOL and their interaction with each other and their relation to disease related factors.

Patients and methods

The study included 25 patients with CU and 25 healthy controls. Urticaria Activity Score (UAS) was used for objective evaluation of the intensity of urticaria. Patients completed a 10-cm visual analogue score (VAS) indicating the overall severity of their itching over the previous 2 weeks. The Dermatology Life Quality Index (DLQI) was used to evaluate patients' QOL. Patients were also assessed for anxiety and depression with the Hospital Anxiety and Depression Scale (HADS). Pittsburgh Sleep Quality Index (PSQI) was used for evaluation of sleep quality and sleep disturbances.

Results

In our CU patients the mean of UAS7 score was 39.72 ± 2.76 and the mean of VAS score was 28 ± 1.34. The mean of DLQI score was 24.8 ± 4.37 indicating severe impact of QOL. CU patients had higher total HADS score when compared to controls; 72% of the patients had depression and 92% had anxiety. By using PSQI, CU patients had significantly longer sleep latency onset, shorter total sleep duration, lower sleep efficiency and higher PSQI scores compared to controls.

Conclusion

CU highly affects the QOL of patients and is associated with higher levels of anxiety, depression and poor sleep quality.

Role of stress in skin diseases: A neuroendocrine-immune interaction view

Psychological stress is a crucial factor in the development of many skin diseases, and the stigma caused by skin disorders may further increase the psychological burden, forming a vicious cycle of psychological stress leading to skin diseases. Therefore, understanding the relationship between stress and skin diseases is necessary. The skin, as the vital interface with the external environment, possesses its own complex immune system, and the neuroendocrine system plays a central role in the stress response of the body. Stress-induced alterations in the immune system can also disrupt the delicate balance of immune cells and inflammatory mediators in the skin, leading to immune dysregulation and increased susceptibility to various skin diseases. Stress can also affect the skin barrier function, impair wound healing, and promote the release of pro-inflammatory cytokines, thereby exacerbating existing skin diseases such as psoriasis, atopic dermatitis, acne, and urticaria. In the present review, we explored the intricate relationship between stress and skin diseases from a neuroendocrine-immune interaction perspective. We explored the occurrence and development of skin diseases in the context of stress, the stress models for skin diseases, the impact of stress on skin function and diseases, and relevant epidemiological studies and clinical trials. Understanding the relationship between stress and skin diseases from a neuroendocrine-immune interaction perspective provides a comprehensive framework for targeted interventions and new insights into the diagnosis and treatment of skin diseases.

The Effectiveness and Safety of Cupping Therapy on CV8 Shenque for Urticaria; a Protocol for Systematic Review and Meta-Analysis

Purpose

Urticaria is a common mast-cell-driven disease that poses a great burden on patients and society. Suggested therapeutic methods include avoidance of triggers and the use of medications, such as H1-antihistamines; however, limitations remain regarding efficacy, dealing with comorbidities, and adverse events. Cupping therapy (CT) at CV8 Shenque has been used in traditional Chinese medicine for the treatment of various dermatological diseases, including urticaria. The efficacy of the treatment has been revealed by previous clinical trials and case reports. This study was performed to provide a protocol for a systematic review and meta-analysis to analyze the effectiveness and safety of CT at CV8 Shenque for urticaria patients.

Patients and Methods

Searches of electronic databases using manual searches and contact with the corresponding authors will be performed using predefined criteria for all randomized controlled trials on CT at CV8 Shenque for urticaria patients. Every part of the process will be conducted by two independent researchers, with conflicts being solved by a third author. The primary outcomes will be symptom scores, quality of life, and effective rate. Secondary outcomes will be adverse events and diagnostic test results. RevMan 5.4 software will be used to perform the meta-analysis. The Cochrane Collaboration "Risk of bias" tool will be used for risk of bias judgments.

Results

Our study will evaluate the effectiveness and safety of CT at CV8 Shenque as a treatment option for urticaria.

Conclusion

This systematic review is the first to investigate the effect of CT at CV8 Shenque for urticaria patients. Our study will provide objective evidence of an alternative approach to urticaria for clinicians and patients.

Palmatine treats urticaria by reducing inflammation and increasing autophagy

Introduction

Chronic spontaneous urticaria (CSU) is mainly manifested as wheals and erythema on the skin accompanied by itching, which will cause emotional anxiety and seriously affect the quality of life in patients. Palmatine (PAL) is a main chemical component of Yajieshaba, which has been found to effectively alleviate the symptoms of food allergy. However, its role and mechanism in CSU remain unclear. The present study aimed to investigate the protective effect of PAL on CSU rats.

Methods

We replicated the CSU rat model by intraperitoneal injection of ovalbumin (OVA) in rats on days 0, 2, 4, and 14, with a double dose given on the last challenge. PAL, loratadine and saline were given by gavage from day 5 to day 14. We observed the skin pathologic changes, mast cell degranulation, immune factor levels, inflammatory response and autophagy-related protein expression in CSU rats.

Results

We found PAL treatment to be effective in alleviating CSU-like skin lesions and reducing itching and mast cell degranulation in rats. Compared with the OVA group, the levels of immune and inflammatory factors were significantly reduced, neutrophil recruitment was alleviated, suggesting a reduced inflammatory response. The autophagy results showed that PAL further increased the expression of LC3, Beclin-1 and p-LKB1, p-AMPK, Atg5, Atg12 and Atg5-Atg12, while P62 and p-p70S6K1 expression decreased. They collectively suggested that autophagic flux was activated after PAL treatment. However, there was an increase in the expression of LC3I, probably due to the fact that PAL induced its accumulation in order to provide substrate for the generation of more LC3II.

Discussion

Overall, PAL had a protective effect on CSU in normal rats, activated the expression of autophagy and improved the inflammatory response.

Common autoimmune diseases and urticaria: the causal relationship from a bidirectional two-sample mendelian randomization study

Objective

The immune response assumes a pivotal role in the underlying mechanisms of urticaria pathogenesis. The present study delves into an investigation of the genetic causal connections between urticaria and prevalent autoimmune afflictions, notably rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ulcerative colitis (UC), and Crohn's disease (CD).

Methods

A bidirectional two-sample Mendelian randomization (MR) analysis was conducted to investigate the causal relationships involving four autoimmune diseases and urticaria. The genome-wide association study (GWAS) summary data of four autoimmune disease were sourced from the IEU OpenGWAS database. The GWAS summary data for urticaria were derived from the Finnish consortium dataset. The principal analytical approach employed in this study was the random-effects inverse variance weighted (IVW) method. Subsequently, a series of sensitivity analyses were performed, encompassing assessments of heterogeneity, horizontal pleiotropy, outliers, "Leave-one-out" analyses, and tests for adherence to the assumption of normal distribution.

Results

The random-effects IVW analysis indicate a positive genetic causal association between RA and urticaria (P < 0.001, OR 95% CI = 1.091 [1.051-1.133]). Conversely, SLE, UC, and CD do not exhibit a significant genetic causal relationship with urticaria. The reverse MR analysis reveals a positive genetic causal linkage between urticaria and SLE (P = 0.026, OR 95% CI = 1.289 [1.031-1.612]). However, the analysis demonstrates no substantial genetic causal relationship between urticaria and RA, UC, or CD. Importantly, the genetic causal assessment absence of heterogeneity, horizontal pleiotropy, and outliers. Furthermore, it remains unaffected by any individual single nucleotide polymorphism (SNP), demonstrating adherence to a normal distribution.

Conclusion

This investigation establishing RA as a predisposing factor for urticaria. Moreover, urticaria as a plausible risk determinant for SLE. Heightened vigilance is recommended among RA patients to monitor the manifestation of urticaria within clinical settings. Similarly, individuals afflicted by urticaria should duly acknowledge the prospective susceptibility to SLE.

Occurrence and risk factors of mental disorders in patients with chronic urticaria

This study aimed to evaluate the prevalence and risk factors of mental disorders in patients with chronic urticaria (CU) in a cohort of adult outpatients. Mental disorders occurred in almost one-sixth of the patients with CU, depression (9.7%), and anxiety (5.0%) being the most prevalent conditions. Furthermore, a significant difference in impairment of quality of life was seen between patients with mental disorders compared to patients without. Although, the prevalence of mental disorders in patients with CU is high, larger clinical studies are needed to investigate and understand the association and risk factors of mental disorders in patients with CU.

Causal relationship between gut microbiota and urticaria: a bidirectional two-sample mendelian randomization study

Background

Cumulative evidence showed an association between gut microbiota and urticaria, but the causal relationship between them is unclear. We aimed to verify whether there is a causal relationship between the composition of gut microbiota and urticaria and explore whether the causal effect was bidirectional.

Methods

We obtained genome-wide association studies (GWAS) summary data of 211 gut microbiota and urticaria from the most extensive available GWAS database. A bidirectional two-sample mendelian randomization (MR) study was used to test the causal relationship between the gut microbiota and urticaria. The MR analysis was primarily performed with the inverse variance weighted (IVW) method, and MR-Egger, weighted median (WM), and MR-PRESSO were performed as sensitivity analyses.

Results

The Phylum Verrucomicrobia (OR 1.27, 95%CI 1.01 to 1.61; p = 0.04), Genus Defluviitaleaceae UCG011 (OR 1.29, 95%CI 1.04 to 1.59; p = 0.02), and Genus Coprococcus 3 (OR 1.44, 95%CI 1.02 to 2.05; p = 0.04) was a risk effect against urticaria. And Order Burkholderiales (OR 0.68, 95%CI 0.49 to 0.99; p = 0.04) and Genus Eubacterium xylanophilum group (OR 0.78, 95%CI 0.62 to 0.99; p = 0.04) were negatively associated with urticaria, suggesting a protective effect. At the same time, urticaria had a positively causal effect on gut microbiota (Genus Eubacterium coprostanoligenes group) (OR 1.08, 95%CI 1.01 to 1.16; p = 0.02). These findings showed no influence by heterogeneity or horizontal pleiotropy. Moreover, most sensitivity analyses showed results consistent with those of IVW analysis.

Conclusion

Our MR study confirmed the potential causal relationship between gut microbiota and urticaria, and the causal effect was bidirectional. Nevertheless, these findings warrant further examination owing to the unclear mechanisms.

Acupuncture Decreases Risk of Hypertension in Patients with Chronic Spontaneous Urticaria in Taiwan: A Nationwide Study

Patients with chronic spontaneous urticaria (CSU) have a higher risk of developing hypertension. This study aimed to determine whether acupuncture could decrease the risk of hypertension in patients with CSU. We enrolled patients newly diagnosed with CSU between 1 January 2008, and 31 December 2018, from the Taiwanese National Health Insurance Research Database. The claims data were assessed from the index date to 31 December 2019. A Cox regression model was used to compare the hazard ratios (HRs) of the two cohorts. The cumulative incidence of hypertension was estimated using the Kaplan-Meier method. After propensity score matching with a 1:1 ratio, 43,547 patients with CSU who received acupuncture were matched with 43,547 patients with CSU who did not receive acupuncture in this study. After considering potential confounding factors, patients who received acupuncture had a significantly lower risk of hypertension than those in the control group (adjusted hazard ratio = 0.56, 95% confidence interval = 0.54-0.58). Patients who received medications combined with acupuncture tended to have the lowest risk of hypertension. This study revealed that acupuncture decreases the risk of hypertension in patients with CSU in Taiwan. The detailed mechanisms can be further clarified through prospective studies.

Why a Complete Response Is the Treatment Aim in Chronic Spontaneous Urticaria

This study investigated the association between urticaria activity and health-related quality of life (HRQoL). Patient evaluations from the ligelizumab Phase 2b clinical trial (N = 382) were pooled (NCT02477332). Daily patient diaries assessed urticaria activity, sleep and activity interference, the dermatology life quality index (DLQI), and work productivity and activity impairment-chronic urticaria (WPAI-CU). The number of DLQI scores, weekly sleep interference scores (SIS7), weekly activity interference scores (AIS7), and overall work impairment (OWI) evaluations with a complete response per weekly urticaria activity score (UAS7) using bands (0, 1-6, 7-15, 16-27, and 28-42) were reported. Over 50% of the patients had a mean DLQI of > 10 at baseline, indicating a significant effect of chronic spontaneous urticaria (CSU) on their HRQoL. Complete response (UAS7 = 0) evaluations corresponded with no impacts on other patient-reported outcomes. In total, 91.1% of UAS7 = 0 evaluations corresponded to DLQI scores of 0-1, 99.7% to SIS7 scores of 0, 99.7% to AIS7 scores of 0, and 85.3% to OWI scores of 0. This was significantly different compared with the UAS7 = 1-6 evaluations (61.9%, 68.5%, 67.7%, and 65.4%, respectively; p < 0.0001). Complete responses to treatment were associated with no impairments on the dermatology-QoL, no interferences with sleep and activity, and significantly improved capacities to work compared to patients who continued to have signs and symptoms, even for those with minimal disease activity.

Neuro-Immuno-Psychological Aspects of Chronic Urticaria

Urticaria is a condition characterized by the development of itchy wheals (hives), angioedema, or both. The pathophysiology of chronic spontaneous urticaria (CSU) is still poorly understood. It is suggested that there is no dominant and independent mechanism of CSU; however, there are different immunological and non-immunological abnormalities that act simultaneously or/and follow each other resulting in clinical symptoms. The latest hypothesis points out that mast cells (MCs) to be activated via autoantibodies in autoallergic or autoimmune mechanism mediators released from degranulated MCs are responsible for the vasoactive and neurospecific effect in CSU. According to many clinical observations, it is suggested that psychological stress can be both a triggering factor in the onset of CSU and a modulating one in the course of the disease and therapy effectiveness. Of importance, the mechanistic background of the psychological stress response in the skin has not yet been fully elucidated. However, of note, a variety of inflammatory mediators, neuropeptides, and neurotransmitters facilitate this phenomenon. This review presents recent findings on the neuro-immuno-psychological aspects of CSU, highlighting an emerging role of neuro-immune interactions. It also points out the usefulness of psychological tools employment for the baseline diagnosis of perceived stress level and the presence of its symptoms. Furthermore, it proposes the implementation of non-invasive interventions to reduce psychological stress and anxiety. A bio-psycho-social approach including psychological support and patient education seems to be as important as traditional pharmacotherapy for CSU. It facilitates the effective control of active disease and a prolonged remission time in this disease.

Sleep Quality as a Predictor of Quality-of-Life and Emotional Status Impairment in Patients with Chronic Spontaneous Urticaria: A Cross-Sectional Study

Chronic Spontaneous Urticaria (CSU) leads to a decreased quality of life in patients because of pruritus and skin lesions. However, there is still little evidence on the impact that a worse sleep quality could have on the quality of life and emotional disorders in these patients. The aims of the present study are to analyze the potential impact of sleep quality on the quality-of-life and emotional status of patients with CSU. A cross-sectional study of 75 CSU patients was performed. Socio-demographic variables and disease activity, quality of life, sleep, sexual disfunction, anxiety, depression and personality traits were collected. A majority of 59 of the patients suffered from poor sleep quality. Sleep quality impairment was associated with worse disease control, greater pruritus and swelling and poorer general and urticaria-related quality-of-life (p < 0.05). Patients with poor sleep quality showed an increased prevalence of anxiety (1.62-fold) and depression risk (3.93-fold). Female sexual dysfunction, but not male, was found to be linked to poorer sleep quality (p = 0.04). To conclude, sleep quality impairment in patients with CSU is related to poor quality-of-life, worse disease control and higher rates of anxiety and depression. Global management of the disease should take sleep quality into account to improve the care of CSU patients.

Acupuncture combined with pricking and cupping therapy is effective in patients with chronic spontaneous urticaria

OBJECTIVE

To determine the effects of acupuncture combined with pricking and cupping therapy on the balance of Th1/Th2 cytokines in patients with chronic spontaneous urticaria (CSU).

METHODS

The medical records of 75 patients with CSU treated in The First Affiliated Hospital of Hebei College of Traditional Chinese Medicine from January 10, 2021 to January 10, 2022 were collected and analyzed retrospectively. Among them, 35 patients treated with traditional therapy were assigned to a control group, and 40 patients treated with acupuncture combined with pricking and cupping therapy to an observation group. The clinical efficacy and adverse reactions in the two groups were compared after therapy. The two groups were also compared in terms of the levels of immunoglobulin (Ig)-E, interleukin (IL)-4 and interferon-γ (INF-γ) before and after therapy. In addition, the visual analogue scale (VAS) for pruritus was adopted for recording the pruritus degree of patients before and after therapy. The Dermatology Quality of Life Index (DLQI) was adopted to compare the quality of life between the two groups before and after therapy. The Hamilton anxiety scale (HAMA) and Hamilton depression rating scale (HAMD) were adopted for comparison of the anxiety and depression between the two groups before and after therapy. Moreover, the Pittsburgh sleep quality index (PSQI) was used to compare sleep quality between the two groups before and after therapy.

RESULTS

The control group showed a significantly lower total response rate than the observation group (P<0.05). Compared with the control group, the observation group showed significantly lower levels of IgE and IL-4, and a higher IFN-γ level and had significantly lower pruritus-VAS, DLQI, HAMA, HAMD and PSQI scores (P<0.05). Additionally, the two groups were not greatly different in adverse reactions (nausea, sleepiness, ecchymosis and dizziness) (P>0.05).

CONCLUSION

Acupuncture combined with pricking and cupping therapy is highly effective in CSU, because it can significantly alleviate the symptoms as well as negative emotions, and improve the quality of life, sleep quality and the balance of Th1/Th2 cytokine in patients.

Comorbidities of Chronic Urticaria: A glimpse into a complex relationship

Chronic Urticaria (CU) is a chronic inflammatory, predominantly mast cell-driven disease, characterized by the development of wheals and/or angioedema for more than 6 weeks. It affects approximately 1%-5% of the total population worldwide and imposes a substantial burden on health-related quality of life, significantly affecting patients' daily life. The economic impact on the health system is also not negligible, with an estimated cost per patient per year of approximately 2.000 $ in the United States. Although the underlying pathophysiology is not fully explored, autoimmune mechanisms have been proposed, including type I ("autoallergy" by means of autoantibodies to self-antigens) and type IIb (autoimmunity). Atopic, autoimmune, and psychiatric disorders are prevalent comorbidities in both children and adults with Chronic Spontaneous Urticaria (CSU). Although malignancies, cardiovascular diseases and other comorbidities have also been reported as associated diseases in patients with CSU, data remain scarce. It is still unknown whether the aforementioned comorbidities share common pathophysiological mechanisms with specific endotypes of CSU. The current review aims to overview current data on comorbidities of CU, and furthermore to comment on the potential linked pathways underlying these diseases.

Chemometrics assisted untargeted metabolomic analysis to explore metabolic alterations in chronic urticaria via LC/Q-TOF/MS/MS

Chronic urticaria (CU) is a common disease characterized by the development of recurrent itchy blisters and/or angioedema lasting longer than 6 weeks. The evidence-based diagnosis of CU is described in the most recent urticaria guideline. Metabolomics has the potential to offer diagnostic biomarkers for the detection and prognosis of diseases and predict the efficacy and safety of pharmaceutical interventions. Determining the variation in metabolites found in the plasma of CU patients (n = 20) and 20 controls has therefore been the goal of this investigation. Samples were analyzed using liquid chromatography quadrupole time-of-flight mass spectrometry after applying acetonitrile precipitation. For the purpose of identifying and characterizing metabolites, the METLIN database was utilized. According to results, 21 metabolites were found to be significantly (VIP score > 0.7, p < .05 and fold analysis >1.5) altered. Differentiations between each group were successful via both OPLS-DA and ROC analysis. While plasma allantoate, homogentisate, indole acetate, proline, phenylalanine levels decreased in CU patients compared to healthy subjects, tryptophan, spermidine, phenyl pyruvate, oleic acid, lysine, valine, ornithine, histidine, glutamate, leucine, kynurenine, hypoxanthine, tyrosine, glucose, creatine and cortisol levels were significantly increased. Diagnosis of CU could be achieved by evaluating the metabolic profile of patients.

Acupuncture and Related Therapies for Chronic Urticaria: A Critical Overview of Systematic Reviews

Background. Chronic urticaria (CU) can severely impair the quality of life. Acupuncture and related therapies have been widely used in the treatment of CU in China. This study aimed to summarize and critically evaluate the methodological and reporting quality of relevant systematic reviews (SRs) and present objective and comprehensive evidence on the effectiveness and safety of acupuncture and related therapies for CU. Methods. Eight electronic databases were searched from inception to October 2021 for SRs examining acupuncture and related therapies for CU, and gray literature was manually searched. Two authors independently identified SRs and extracted data. The methodological and reporting quality of these SRs were assessed by the Assessment of Multiple Systematic Reviews 2 (AMSTAR 2) tool and preferred reporting items for SRs and meta-analyses (PRISMA, 2020), respectively. In addition, the risk of bias in systematic reviews (ROBIS) was used to evaluate the risk of bias. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework was applied to evaluate the quality of evidence for outcome measures. Results. In total, 23 SRs, including a total of 11 outcome indicators, were published before October 2021. The AMSTAR-2 results showed that the methodological quality of all SRs was critically low; items 2, 3, 7, 9, 10, and 16 were found to have particularly low quality. For PRISMA, the reporting quality of the included SRs was unsatisfactory, and major reporting flaws were observed in the search strategy, synthesis method, certainly assessment, reporting biases, registrations, and financial support of the included SRs. For ROBIS, 22 SRs (95.65%) had a high risk of bias. Among the 55 outcomes assessed using the GRADE framework, there were 3 (5.45%) outcomes with moderate-quality evidence, 6 (10.91%) outcomes with low-quality evidence, and 46 (83.64%) outcomes with very low-quality evidence. We found the moderate quality of evidence indicating that the total effective rate and curing rate of the acupuncture group were higher than those of the western medicine group, and the recurrence rate was lower than that of the western medicine group. Conclusions. Acupuncture and related therapies for the treatment of CU are supported by low-quality evidence-based medicine. However, considering the poor quality of these SRs, we suggest that studies with more rigorous designs, larger sample sizes, and higher methodological and reporting quality are necessary to provide stronger evidence. Registration. The protocol for this study has been registered (PROSPERO registration number: CRD42021259131).

The burden of symptomatic patients with chronic spontaneous urticaria: a real-world study in Korea

BACKGROUND/AIMS

Chronic spontaneous urticaria (CSU) poses a considerable burden both on the quality of life (QoL) of individual patients and on healthcare systems. Real‑world data evaluating the disease burden of CSU are limited in this country. This study evaluated the disease burden and healthcare resource utilization (HRU) among symptomatic CSU patients.

METHODS

This multicenter, noninterventional, retrospective, and cross-sectional study assessed CSU patients symptomatic for more than 6 months despite step-wise H1-antihistamine medications. Primary outcomes included Urticaria Activity Score over 7 days (UAS7) and Chronic Urticaria QoL scale (CU-QoL). Secondary outcomes included EuroQol 5-Dimension 5-Level (EQ-5D-5L), Dermatology Life Quality Index (DLQI), association of disease activity with QoL, medications used for the past 6 months, and HRU.

RESULTS

Five hundred patients with CSU were enrolled. Mean disease duration was 3.7 years. Based on UAS7, 22.2% of patients were in well-controlled status and 31.2%, 28.4%, and 18.2% of them had mild, moderate, and severe disease, respectively. Mean CU-QoL and DLQI scores were 57.5 ± 29.7 and 10.2 ± 7.6, respectively, while the EQ-5D-5L utility score was 0.8 ± 0.2. H1-antihistamines were prescribed to 95% of patients, while omalizumab was prescribed to 33% of patients. Most patients (98%) had outpatient visits in the past 6 months. Negative correlations were noted between UAS7 and CU-QoL, EQ-5D-5L, EQ-5D-5L visual analog scale scores, but a positive correlation was noted with DLQI score (p < 0.001 for all). The number of outpatient department visits increased with disease activity (p = 0.001).

CONCLUSION

CSU affects QoL, leading to increased HRU, particularly in patients with severe disease.

Type D Personality Is Associated with Poorer Quality of Life in Patients with Chronic Spontaneous Urticaria: A Cross-sectional Study

Type D personality (TDp) is a stable personality type that has been associated with poor quality of life in the general population and in patients with a variety of diseases, such as cancer, cardiac diseases, and dermatological diseases (e.g. psoriasis). To date, the potential association between chronic spontaneous urticaria and TDp has not been studied. The aim of this study is to analyse the impact of TDp on patients with chronic spontaneous urticaria, regarding mood disturbances, quality of life, sexuality, and sleep disturbances. A cross-sectional study including 75 patients with chronic spontaneous urticaria was performed. Data on socio- demographic variables and disease activity, quality of life, sleep, sexual dysfunction, anxiety, depression and TDp were collected using validated questionnaires. TDp was present in 28% (21/75) of the patients. Although TDp was not related to worse disease control, the presence of anxiety and depression was higher in patients with TDp. Regarding quality of life, TDp was associated with poorer quality of life and higher frequency of sleep disturbances. Prevalence of TDp in patients with chronic spontaneous urticaria is similar to that in the general population. It is associated with mood status disturbances and worse quality of life regardless of disease severity, especially in the emotional and psychological domains. This group of patients could benefit from additional psychological support as a complement to their medical treatment.

The Burden on Cohabitants of Patients with Chronic Spontaneous Urticaria: A Cross-Sectional Study

Chronic Spontaneous Urticaria (CSU) has been associated with patients’ poor quality of life. Despite being a chronic disease that could alter the quality of life of the people who live with patients, the potential burden on their cohabitants has not been studied to date. The aim of this study is to analyze the relationship between the patient’s quality of life, disease control, disease duration and family quality of life and the cohabitant’s mood disturbances, sexual dysfunction, type D personality and sleep quality. A cross-sectional study including patients suffering from CSU and their cohabitants was performed. Sociodemographic variables and disease activity, quality of life, sleep, sexual disfunction, anxiety, depression and type D personality were collected using validated questionnaires. Sixty-two subjects, 31 CSU patients and 31 cohabitants, were included in the study. Worse disease control and poorer quality of life in patients were associated with poorer family quality of life and higher rates of anxiety among the cohabitants (p < 0.05). Patients’ poor quality of life was associated with reduced sexual satisfaction among the cohabitants (p < 0.05). Long disease duration (>10 years) was associated with an increased prevalence of type D personality among the cohabitants (prevalence ratio: 2.59, CI 95% 1.03−7.21). CSU seems to have an impact on the quality of life of cohabitants, especially in terms of increased rates of anxiety, poorer quality of life and reduced sexual satisfaction. The prolonged course of the disease could be associated with the increased presence of non-adaptative personality traits.

Multicentric and Observational Study of Omalizumab for Chronic Spontaneous Urticaria in Real-Life in Colombia

Background

Although chronic urticaria (CU) is a common, cause of medical consulting both in general practitioners and allergist specialists worldwide, there is little information about its behavior and management in Latin America. Currently, national and international guidelines recommend using Omalizumab for cases refractory to management with antihistamines. Despite advances in the knowledge of Omalizumab for the management of CU, although there are few studies in underdeveloped countries, there are many studies evaluating the impact of Omalizumab treatment. There is not clinical information related with CSU-Omalizumab in patient settled in the Caribbean area. This research aims to evaluate the management of CU with Omalizumab in a real-life scenario in Colombia.

Methodology

We conducted an observational, descriptive, and retrospective study with patient recruitment between 2014 and 2017 of individuals diagnosed with Chronic Urticaria (CU) treating allergology specialists in five Colombian cities. We included patients with CU who failed to achieve disease control after treatment for 4 weeks with fourfold doses of second-generation H1-antihistamines, as recommended by the EAACI/GA²LEN/EDF/WAO guidelines and who received treatment with Omalizumab.

Results

We included 123 patients, 73.1% (n = 90) were women. The mean age was 47.1 years (Standard Deviation, SD: 16.2). The median of the total months of disease evolution was 30 (IQR = 13–58). 81.3 % (n = 100) of patients were diagnosed with chronic spontaneous urticarial (CSU). 4.8% (n = 6) had inducible CU (CIndU), and 13.8% (n = 17) reported mixed urticaria (spontaneous CU with at least one inducible component). Regarding emotional factors, 34.9% (n = 43) of subjects indicated anxiety symptoms, 34.1% (n = 42) had exacerbations associated with stress, and 14.6% (n = 18) manifested episodes of sadness. The percentage of patients with CSU controlled according to medical criteria at 3 months with Omalizumab were 80% (n = 80/100) and at 6 months 87% (n = 87/100). The frequency of adverse events was 29.2% (n = 36), with headache being the most frequent adverse event.

Conclusions

This real-life study with Omalizumab at CU describes percentages of effectiveness and safety similar to those observed in pivotal and real-life studies conducted in other regions around the world.

Salivary Cortisol Values and Personality Features of Atopic Dermatitis Patients: A Prospective Study

BACKGROUND

Atopic dermatitis (AD) patients commonly experience psychological stress and impaired psychosocial functioning.

OBJECTIVE

The aim of this study was to compare patients' salivary cortisol levels with AD severity and other associated stress-related psychological measures/parameters.

METHODS

This prospective study analyzed salivary cortisol levels (enzyme-linked immunosorbent assay) in 84 AD patients (42 symptomatic patients and 42 asymptomatic patients). Each subject filled out the Perceived Stress Scale (PSS), Brief Illness Perception Questionnaire, and the Crown-Crisp Experiential Index, which concerns personality features.

RESULTS

Increased cortisol values were found in both groups and were not dependent on disease severity (Scoring Atopic Dermatitis [SCORAD]) and PSS. Patients with severe AD had significantly lower cortisol levels than those with moderate and mild AD (P = 0.042). The PSS levels were not dependent on SCORAD but correlated with the perceived effect of AD on emotional states (Illness Perception Questionnaire 8), personality traits, anxiety, and depression (P < 0.001).

CONCLUSIONS

The severity of perceived stress in AD patients is not adequately measured by salivary cortisol levels nor SCORAD; it does, however, correlate with the impact of AD on patients' emotional states and personality features (anxiety, depression). All AD patients, regardless of disease severity, should be assessed for impacts of stress, and a multidisciplinary approach should address mental wellness.

Itch in Adult Population with Type 2 Diabetes Mellitus: Clinical Profile, Pathogenesis and Disease-Related Burden in a Cross-Sectional Study

BACKGROUND

Despite growing interest in itch, data regarding itch in type 2 diabetes mellitus (DM2) are still limited, and mostly based on outdated studies. This study aimed to evaluate the clinical characteristics of itch in the adult population with DM2 and explore potential underlying causes.

METHODS

The study group consisted of 109 adult patients with DM2. Standardized questionnaires were completed in order to assess the itch intensity [Numerical Rating Scale (three days, 24hours) (NRS)] and the Four-item Itch Questionnaire (4IIQ) and to assess the psychological impact of itch [ItchyQoL, Six-Item Stigmatization Scale (6-ISS), Hospital Anxiety and Depression Scale (HADS)]. Skin dryness was evaluated clinically and by non-invasive assessment of epidermis moisturizing. Neuropathy was assessed using the clinical Katzenwadel neuropathy scale.

RESULTS

Itch occurred in 35.8% of adult patients with DM2, with NRSmax three days 6.31 ± 2.16 and 8.1 ± 3.5 points in 4IIQ. Itchy patients have had significantly higher FPG levels compared with the non-itchy population (p = 0.01). Patients with itch had a significantly higher possibility of neuropathy compared with non-itchy subjects (p < 0.01). Skin xerosis was significantly more advanced in patients with itch compared to those without (p < 0.01). The mean ItchyQol score was assessed as 41.2 ± 13.4 points, indicating mild life quality impairment and correlated positively with itch intensity. Itchy subjects had significantly higher scores in both anxiety and depression dimensions of HADS (in each p < 0.01).

CONCLUSIONS

We suggest that the primary cause of itch is prolonged poor diabetes control with altered glucose and insulin levels, subsequently causing skin dryness and neuropathy in long-lasting DM2.

Management of psychocutaneous disorders: A practical approach for dermatologists

Psychodermatology is a growing specialty which is gaining momentum in different parts of the world. It focuses on the connection between skin and psyche. Psychocutaneous conditions are characterized by those disorders where stress is the key element in exacerbating skin conditions or flare ups of dermatoses like psoriasis and atopic dermatitis. There is a direct relationship of stress with the course, and prognosis of the skin disease. In some situations, there is no skin condition but the lesions are self-inflicted and such disorders are always associated with underlying psychopathology or psychological conflicts. Sometimes emotional problems are more prominent as a result of having skin disease, and the psychological consequences may be more severe than the physical symptoms. Management of these conditions require a combination of psychpharmacology, psychotherapy, and liaison clinics of psychiatry and dermatology. This review focuses on the common management approach which can be adopted by dermatologists in treating patients with psychodermatological disorders, improving doctor-patient relationship and therapeutic bond.
