Psoriasis: depression, anxiety, smoking, and drinking habits

The prevalence of anxiety in respiratory and sleep diseases: A systematic review and meta-analysis

BACKGROUND

Anxiety is common in those with chronic physical health conditions and can have significant impacts on both quality of life and physical health outcomes. Despite this, there are limited studies comprehensively investigating the prevalence of anxiety in respiratory and sleep medicine settings. This systematic review and meta-analysis aims to provide insight into the global prevalence of anxiety symptoms/disorders in respiratory and sleep medicine outpatients.

METHODS

PubMed, Embase, Cochrane, PsycINFO and Google Scholar databases were searched from database inception to January 23, 2023 for studies assessing the prevalence of anxiety in adult (≥16 years) respiratory and sleep medicine outpatients. Data was screened and extracted independently by two investigators. Anxiety was measured using various self-report questionnaires, structured interviews, and/or patient records. Using CMA software for the meta-analysis, a random-effects model was used for pooled estimates, and subgroup analysis was conducted on relevant models using a mixed-effects model.

RESULTS

116 studies were included, featuring 36,340 participants across 40 countries. The pooled prevalence of anxiety was 30.3 % (95%CI 27.9-32.9 %, 10,679/36,340). Subgroup analysis found a significant difference across type of condition, with pulmonary tuberculosis the highest at 43.1 % and COVID-19 outpatients the lowest at 23.4 %. No significant difference was found across anxiety types, country or age. Female sex and the use of self-report measures was associated with significantly higher anxiety estimates.

CONCLUSIONS

Anxiety is a common experience amongst patients in respiratory and sleep medicine outpatient settings. Thus, it is crucial that anxiety identification and management is considered by physicians in the field.

REGISTRATION

The protocol is registered in PROSPERO (CRD42021282416).

Factors associated with a better treatment efficacy among psoriasis patients: a study based on decision tree model and logistic regression in Shanghai, China

BACKGROUND

Many effective therapies for psoriasis are being applied in clinical practice in recent years, however, some patients still can't achieve satisfied effect even with biologics. Therefore, it is crucial to identify factors associated with the treatment efficacy among psoriasis patients. This study aims to explore factors influencing the treatment efficacy of psoriasis patients based on decision tree model and logistic regression.

METHODS

We implemented an observational study and recruited 512 psoriasis patients in Shanghai Skin Diseases Hospital from 2021 to 2022. We used face-to-face questionnaire interview and physical examination to collect data. Influencing factors of treatment efficacy were analyzed by using logistic regression, and decision tree model based on the CART algorithm. The receiver operator curve (ROC) was plotted for model evaluation and the statistical significance was set at P < 0.05.

RESULTS

The 512 patients were predominately males (72.1%), with a median age of 47.5 years. In this study, 245 patients achieved ≥ 75% improvement in psoriasis area and severity index (PASI) score in week 8 and was identified as treatment success (47.9%). Logistic regression analysis showed that patients with senior high school and above, without psoriasis family history, without tobacco smoking and alcohol drinking had higher percentage of treatment success in patients with psoriasis. The final decision tree model contained four layers with a total of seventeen nodes. Nine classification rules were extracted and five factors associated with treatment efficacy were screened, which indicated tobacco smoking was the most critical variable for treatment efficacy prediction. Model evaluation by ROC showed that the area under curve (AUC) was 0.79 (95%CI: 0.75 ~ 0.83) both for logistic regression model (0.80 sensitivity and 0.69 specificity) and decision tree model (0.77 sensitivity and 0.73 specificity).

CONCLUSION

Psoriasis patients with higher education, without tobacco smoking, alcohol drinking and psoriasis family history had better treatment efficacy. Decision tree model had similar predicting effect with the logistic regression model, but with higher feasibility due to the nature of simple, intuitive, and easy to understand.

Quantitative analysis of social influence and digital piracy contagion with differential equations on networks

Illegal file sharing of copyrighted contents through popular file sharing networks poses an enormous threat to providers of digital contents, such as, games, softwares, music and movies. Though empirical studies of network effects on piracy is a well-studied domain, the dynamics of peer effect in the context of evolving social contagion has not been enough explored using dynamical models. In this research, we methodically study the trends of online piracy with a continuous ODE approach and differential equations on graphs to have a clear comparative view. We first formulate a compartmental model to study bifurcations and thresholds mathematically. We later move on with a network-based analysis to illustrate the proliferation of online piracy dynamics with an epidemiological approach over a social network. We figure out a solution for this online piracy problem by developing awareness among individuals and introducing media campaigns, which could be a valuable factor in eradicating and controlling online piracy. Next, using degree-block approximation, network analysis has been performed to investigate the phenomena from a heterogeneous approach and to derive the threshold condition for the persistence of piracy in the population in a steady state. Considering the dual control of positive peer influence and media-driven awareness, we examine the system through realistic parameter selection to better understand the complexity of the dynamics and suggest policy implications.

Resting-state fMRI reveals changes within the anxiety and social avoidance circuitry of the brain in mice with psoriasis-like skin lesions

Psoriasis is an autoimmune skin disease that often co-occurs with psychological morbidities such as anxiety and depression, and psychosocial issues also lead psoriasis patients to avoid other people. However, the precise mechanism underlying the comorbidity of psoriasis and anxiety is unknown. Also, whether the social avoidance phenomenon seen in human patients also exists in psoriasis-like animal models remains unknown. In the present study, anxiety-like behaviours and social avoidance-like behaviours were observed in an imiquimod-induced psoriasis-like C57-BL6 mouse model along with typical psoriasis-like dermatitis and itch-like behaviours. The 11.7T resting-state functional magnetic resonance imaging showed differences in brain regions between the model and control group, and voxel-based morphometry showed that the grey matter volume changed in the basal forebrain region, anterior commissure intrabulbar and striatum in the psoriasis-like mice. Seed-based resting state functional connectivity analysis revealed connectivity changes in the amygdala, periaqueductal gray, raphe nuclei and lateral septum. We conclude that the imiquimod-induced psoriasis-like C57-BL6 mouse model is well suited for mechanistic studies and for performing preclinical therapeutic trials for treating anxiety and pathological social avoidance in psoriasis patients.

Global Prevalence of Anxiety in Adult Cardiology Outpatients: A Systematic Review and Meta-analysis

Anxiety and anxiety disorders are associated with adverse cardiovascular outcomes, and reduced quality of life. Despite this, no comprehensive study on the global prevalence of anxiety symptoms and disorders among adult cardiology outpatients exists. This systematic review and meta-analysis aims to provide cardiologists with a precise estimate of the prevalence of anxiety in their outpatient clinics. PubMed, Embase, Cochrane and PsycINFO databases and Google Scholar were searched from database inception to January 23, 2023. Data characteristics were extracted independently by 2 investigators. Ninety-three studies, n = 36,687 participants across 31 countries, were included. Global prevalence of anxiety symptoms/disorders was 28.9% (95%CI 25.7-32.4; 8927/36, 687; I2 = 97.33; n = 93). The highest rates were found in patients presenting with hypertension, 43.6%. Subgroup analyses revealed higher prevalence estimates when using self-report screening compared to gold-standard diagnostic interview. When using diagnostic interview, the highest rates were reported in outpatients with undifferentiated chest pain/palpitations, 19·0%. Panic disorder was the most frequent diagnosis 15.3%, and rates were significantly higher in patients with undifferentiated chest pain/palpitations compared to ischemic heart disease. Higher rates of anxiety were found in studies of outpatients from developing countries, and female outpatients tended to have higher rates compared to males. Anxiety occurred frequently among cardiology outpatients and at a higher rate than estimated in the general population. Given the impact anxiety has on patient outcomes, it is important that effective identification and management strategies be developed to support cardiologists in identifying and treating these conditions in their clinics.

Drug Target Identification and Drug Repurposing in Psoriasis through Systems Biology Approach, DNN-Based DTI Model and Genome-Wide Microarray Data

Psoriasis is a chronic skin disease that affects millions of people worldwide. In 2014, psoriasis was recognized by the World Health Organization (WHO) as a serious non-communicable disease. In this study, a systems biology approach was used to investigate the underlying pathogenic mechanism of psoriasis and identify the potential drug targets for therapeutic treatment. The study involved the construction of a candidate genome-wide genetic and epigenetic network (GWGEN) through big data mining, followed by the identification of real GWGENs of psoriatic and non-psoriatic using system identification and system order detection methods. Core GWGENs were extracted from real GWGENs using the Principal Network Projection (PNP) method, and the corresponding core signaling pathways were annotated using the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Comparing core signaling pathways of psoriasis and non-psoriasis and their downstream cellular dysfunctions, STAT3, CEBPB, NF-κB, and FOXO1 are identified as significant biomarkers of pathogenic mechanism and considered as drug targets for the therapeutic treatment of psoriasis. Then, a deep neural network (DNN)-based drug-target interaction (DTI) model was trained by the DTI dataset to predict candidate molecular drugs. By considering adequate regulatory ability, toxicity, and sensitivity as drug design specifications, Naringin, Butein, and Betulinic acid were selected from the candidate molecular drugs and combined into potential multi-molecule drugs for the treatment of psoriasis.

Association between pregnancy, and lactation after delivery and depressive symptoms in premenopausal Korean women and multilevel approach according to household composition: Result from the Korea Community Health Survey in 2019

OBJECTIVE

To evaluate the association between pregnancy, lactation after delivery and depressive symptoms in Korean women and to explore the associations according to household composition.

METHODS

We included 34,321 premenopausal women from the Korea Community Health Survey in 2019, a population-based cross-sectional study. We categorized the premenopausal women into 3 groups by questions about whether they were currently in menstruation: reference (women who were not pregnant or lactating after delivery), pregnancy, and lactation after delivery. Depressive symptoms (PHQ-9 ≥ 5) were assessed through questionnaires with trained interviewers. Multiple logistic regression analysis were performed.

RESULTS

Among 34,321 participants, 20,790 (60.6 %) had depressive symptoms. In the fully adjusted model, we found a significant association between mild depressive symptoms in lactated women after delivery (odds ratio [OR], 95 % confidence interval [CI] = 1.32 [1.04-1.65]) compared to a reference. Compared to reference, the association between women who were lactation after delivery and depressive symptoms was particularly noticeable in women living in families of 2-generation (OR, 95 % CI = 1.29 [1.00-1.65]) and 3-generation (OR, 95 % CI = 2.53 [1.31-4.89]).

LIMITATIONS

We utilized self-reported data on pregnancy and lactation after delivery, this exposure variable may be underestimated.

CONCLUSION

Our study observed associations between lactated women after delivery and depressive symptoms. This association was more pronounced in women living in 3-generation.

Effects of online care on functional and psychological outcomes in patients with psoriasis: A randomized controlled trial

BACKGROUND

The impact of online care on patients' functional and psychological outcomes is critical to determine yet still unknown.

OBJECTIVE

To evaluate how a novel online health model that facilitates physician-patient collaboration compares with in-person care for improving functional status and mental health of patients with psoriasis.

METHODS

This 12-month randomized controlled equivalency trial randomly assigned patients with psoriasis 1:1 to receive online or in-person care. Functional impairment and depression were assessed at baseline and at 3-month intervals using the 5-level EuroQol-5 Dimensions index and Patient Health Questionnare-9.

RESULTS

Overall, 296 patients were randomly assigned to the online or in-person groups. The between-group difference in overall improvement in the EuroQol Visual Analogue Scale was -0.002 (95% confidence interval, -2.749 to 2.745), falling within an equivalence margin of ±8. The between-group difference in overall improvement in the 5-level EuroQol-5 Dimensions index was 0 (95% confidence interval, -0.003 to 0.003), falling within an equivalence margin of ±0.1. The between-group difference in overall improvement in Patient Health Questionnare-9 score was -0.33 (95% CI, -1.20 to 0.55), falling within an equivalence margin of ±3.

LIMITATIONS

Slightly different attrition rates between online and in-person arms (11% vs 9%), but no impact on outcomes.

CONCLUSION

The online health model was equivalent to in-person care for reducing functional impairment and depressive symptoms in patients with psoriasis.

Psoriasis and Post-Surgical Infections in Primary Total Knee Arthroplasty: An Analysis of 10,727 Patients

BACKGROUND

Psoriasis is a dermatologic condition characterized by erythematous plaques that may increase wound complications and deep infections following total knee arthroplasty (TKA). There is a paucity of evidence concerning the association of this disease and complications after TKA. This study aimed to determine if patients who have psoriasis vs non-psoriatic patients have differences in demographics and various comorbidities as well as post-operative infections, specifically the following: (1) wound complications; (2) cellulitic episodes; and (3) deep surgical site infections (SSIs).

METHODS

We identified 10,727 patients undergoing primary TKA utilizing an institutional database between January 1, 2017 and April 1, 2019. A total of 133 patients who had psoriasis (1.2%) were identified using International Classification of Diseases, Tenth Revision codes and compared to non-psoriatic patients. The rate of wound complications, cellulitic episodes, and deep SSIs were determined. After controlling for age and various comorbidities, multivariate analyses were performed to identify the associated risks for post-operative infections.

RESULTS

Psoriasis patients showed an increased associated risk of deep SSIs (3.8%) compared to non-psoriasis patients (1.2%, P = .023). Multivariate analyses demonstrated a significant associated risk of deep SSIs (odds ratio 7.04, 95% confidence interval 2.38-20.9, P < .001) and wound complications (odds ratio 4.44, 95% confidence interval 1.02-19.2, P = .047).

CONCLUSION

Psoriasis is an inflammatory dermatologic condition that warrants increased pre-operative counseling, shared decision-making, and infectious precautions in the TKA population given the increased risk of wound complications and deep SSIs. Increased vigilance is required given the coexistence of certain comorbidities with this population, including depression, substance use disorder, smoking history, gastroesophageal reflux disease, and inflammatory bowel disease.

Psychopathology and Alexithymia in Patients with Moderate-to-Severe Psoriasis: Development of a Novel Index with Prognostic Value

BACKGROUND

Psoriasis is a chronic, relapsing, inflammatory disease with a high risk of developing mental health difficulties.

OBJECTIVE

The purposes of the study were to evaluate in moderate-to-severe psoriasis (a) the prevalence of depression and psychopathology, (b) the relationship between depression, psychopathology symptoms, and alexithymia, including its three dimensions, difficulty in identifying feelings (DIF), difficulty in describing feelings (DDF), and externally oriented thinking (EOT), and (c) to establish a novel index for the development of depression according to patients' psychopathological profile.

METHODS

In 104 patients, alexithymia was evaluated with the Toronto Alexithymia Scale (TAS-20), depression with the Beck Depression Inventory (BDI), and psychopathology with the Brief Symptom Inventory SCL-90 (SCL90). A psychopathology index that combines information from the BDI and SCL90 scales was constructed and the performance of the index with alexithymia was examined.

RESULTS

Female patients and active smokers score higher on BDI and SCL90 scales. Overweight patients tend to score arithmetically higher. The psychopathology index developed correlates significantly with age, DIF, DDF, and TAS-20. DIF, DDF, and TAS-20 are significant predictors of the psychopathology index. Patients with alexithymia/possible alexithymia are six times as likely to score higher in one of the psychopathology scales.

CONCLUSIONS

Alexithymia is a significant factor in the development of psychopathology in psoriasis patients. The use of the proposed novel psychopathology index could be essential in order to identify patients with moderate-to-severe psoriasis who are more likely to experience depression and psychopathology. This could have an impact on the decision-making of psoriasis treatment and monitoring of the patient.

Orchestrated Cytokines Mediated by Biologics in Psoriasis and Its Mechanisms of Action

Psoriasis is an autoimmune disease mediated by disturbed T cells and other immune cells, and is defined by deep-red, well-demarcated skin lesions. Due to its varied etiologies and indefinite standard pathogenesis, it is challenging to consider the right treatment exclusively for each psoriasis patient; thus, researchers yearn to seek even more precise treatments other than topical treatment and systemic therapy. Using biologics to target specific immune components, such as upregulated cytokines secreted by activated immune cells, is the most advanced therapy for psoriasis to date. By inhibiting the appropriate pro-inflammatory cytokines, cellular signaling can be altered and, thus, can inhibit further downstream inflammatory pathways. Herein, the roles of cytokines with their mechanisms of action in progressing psoriasis and how the usage of biologics alleviates cellular inflammation are discussed. In addition, other potential pro-inflammatory cytokines, with their mechanism of action, are presented herein. The authors hope that this gathered information may benefit future research in expanding the discovery of targeted psoriasis therapy.

Perception of the threat, mental health burden, and healthcare-seeking behavior change among psoriasis patients during the COVID-19 pandemic

This study aimed to investigate the perceived threat, mental health outcomes, behavior changes, and associated predictors among psoriasis patients during the COVID-19 pandemic. The COVID-19 has been known to increase the health risks of patients with psoriasis owing to patients’ immune dysregulation, comorbidities, and immunosuppressive drug use. A total of 423 psoriasis patients not infected with COVID-19 was recruited from the Department of Dermatology, National Taiwan University Hospital Hsin-Chu Branch, Chang Gung Memorial Hospital, and China Medical University Hospital from May 2020 to July 2020. A self-administered questionnaire was used to evaluate the perceived threat, mental health, and psychological impact on psoriasis patients using the Perceived COVID-19-Related Risk Scale score for Psoriasis (PCRSP), depression, anxiety, insomnia, and stress-associated symptoms (DAISS) scales, and Impact of Event Scale-Revised (IES-R), respectively. Over 94% of 423 patients with psoriasis perceived threat to be ≥ 1 due to COVID-19; 18% of the patients experienced psychological symptoms more frequently ≥ 1, and 22% perceived psychological impact during the pandemic to be ≥ 1. Multivariable linear regression showed that the higher psoriasis severity and comorbidities were significantly associated with higher PCRSP, DAISS, and IES-R scores. The requirement for a prolonged prescription and canceling or deferring clinic visits for psoriasis treatment among patients are the two most common healthcare-seeking behavior changes during the COVID-19 pandemic. Psoriasis patients who perceived a higher COVID-19 threat were more likely to require a prolonged prescription and have their clinic visits canceled or deferred. Surveillance of the psychological consequences in psoriasis patients due to COVID-19 must be implemented to avoid psychological consequences and inappropriate treatment delays or withdrawal.

Stigmatization in Patients With Psoriasis: A Mini Review

Psoriasis is a chronic and recurrent immune-related skin disease that often causes disfigurement and disability. Due to the visibility of lesions in patients and inadequate understanding of dermatology knowledge in the general public, patients with psoriasis often suffer from stigma in their daily lives, which has adverse effects on their mental health, quality of life, and therapeutic responses. This review summarized the frequently used questionnaires and scales to evaluate stigmatization in patients with psoriasis, and recent advances on this topic. Feelings of Stigmatization Questionnaire, Questionnaire on Experience with Skin Complaints, and 6-item Stigmatization Scale have been commonly used. The relationship between sociodemographic characteristics, disease-related variables, psychiatric disorders, quality of life, and stigmatization in patients with psoriasis has been thoroughly investigated with these questionnaires. Managing the stigmatization in patients with psoriasis needs cooperation among policymakers, dermatologists, psychologists, psychiatrists, researchers, and patients. Further studies can concentrate more on these existing topics, as well as other topics, including predictors of perceived stigmatization, stigmatization from non-patient groups, influence of biologics on stigmatization, and methods of coping with stigmatization.

How do mindfulness-based programmes improve anxiety, depression and psychological distress? A systematic review

This study aimed to systematically review studies which conducted a controlled mediation analysis in order to examine the potential mechanisms which underlie mindfulness-based programme’s (MBPs) effects on anxiety, depression and psychological distress in any health or mental health population. Searches of six databases (Medline (Ovid), PsycINFO, Cochrane Central Register of Controlled Trials, EMBASE, Cinahal Plus and Cochrane Reviews) were undertaken in September 2020. After removing duplicates, 2052 records were screened, of these 1822 were excluded based on the abstract and 230 were further assessed for eligibility against the full study inclusion criteria. Full texts were acquired for the 11 studies which met the inclusion criteria. The quality of the methodologies of each of these 11 studies were assessed using the Cochrane risk of bias tool (Higgins et al., 2011). The quality of the findings from each study relating to the hypothesised mechanisms of action of the MBP reviewed were evaluated using Alsubaie et al. (2017)’s framework for abstracting and interpreting mechanistic study quality, derived from recommendations made by Kazdin (2007, 2009). We found preliminary evidence that MBCT/MBSR treatment effects on anxiety and depression may be mediated by hypothesised mechanisms, such as mindfulness, rumination, worry, self-compassion, cognitive reactivity, aversion, attention regulation skills and positive affect. An overall lack of methodological rigour does preclude us from making any definitive conclusions on causality. The results from this study do however provide some insights into what the potential causal pathways connecting MBPs with improved anxiety and depression might be.

A real-world economic analysis of biologic therapies for moderate-to-severe plaque psoriasis in Italy: results of the CANOVA observational longitudinal study

BACKGROUND

Psoriasis is a chronic immune-mediated inflammatory skin disease which can also involve joints. It is often associated with burdensome comorbidities which negatively impact prognosis and quality of life (QoL). Biologic agents have been shown to be effective in controlling disease progression, but their use is associated with higher costs compared with traditional systemic treatments. The economic analysis of the CANOVA (EffeCtiveness of biologic treAtmeNts for plaque psOriasis in Italy: an obserVAtional longitudinal study of real-life clinical practice) study aims to assess the costs and cost-effectiveness of biologics in a real-world context in Italy.

METHODS

The annualised overall direct costs of moderate-to-severe plaque psoriasis management, the annualised cost of biologic drugs and the cost per responder in the Italian National Health System perspective were assessed. More specifically, the cost per response and cost per sustained response of the most prescribed biologic therapies for the treatment of moderate-to-severe plaque psoriasis within the CANOVA study were assessed using the Psoriasis Area Severity Index (PASI) at several score levels (75, 90 and 100%).

RESULTS

The most frequently used biologic therapies for plaque psoriasis were secukinumab, ustekinumab, adalimumab originator, and ixekizumab. Cost of biologics was the driver of expenditure, accounting for about 98% of total costs. Adalimumab originator was the biologic with the lowest cost per responder ratio (range: €7848 - €31,378), followed by secukinumab (range: €9015 - €33,419). Ustekinumab (range: €11,689 - €39,280) and ixekizumab (range: €11,092 - €34,289) ranked respectively third and fourth, in terms of cost-effectiveness ratio. As concerns the cost per sustained response analysis, secukinumab showed the lowest value observed (€21,375) over the other options, because of its high response rate (86% vs. 60-80%), which was achieved early in time.

CONCLUSION

Biologic therapy is a valuable asset for the treatment of moderate-to-severe plaque psoriasis. Concomitant assessment of treatment costs against the expected therapeutic response over time can provide physicians and payers additional insights which can complement the traditional risk-benefit profile assessment and drive treatment decisions.

Self-practice among patients with psoriasis: University hospital experience

OBJECTIVES

This study aimed to assess the self-care practices of patients with psoriasis and factors affecting them.

METHODS

A cross-sectional study was conducted on 110 adult patients with confirmed diagnosis of psoriasis. Each patient underwent a personal structured interview with the physician using two predetermined questionnaires, one for assessing self-care practices and another for evaluating patients' knowledge of their disease and sociodemographic and clinical features.

RESULTS

Most studied patients had poor level of self-care practices and knowledge. Patients' level of self-care was positively associated with the level of the knowledge of their disease. Poor level of self-care practice was significantly associated with low level of education, disease severity, and Psoriasis Area and Severity Index score.

CONCLUSION

Patients with low level of education or disease knowledge will mostly have poor self-care behavior.

Alcohol misuse is associated with poor response to systemic therapies for psoriasis: findings from a prospective multicentre cohort study

BACKGROUND

Factors that might influence response to systemic treatment for moderate-to-severe psoriasis are varied, and generally, are poorly understood, aside from high bodyweight, suggesting that other unidentified factors may be relevant in determining response to treatment. The impact of alcohol misuse on treatment response has not been previously investigated.

OBJECTIVES

To investigate whether alcohol misuse is associated with poor response to treatment for psoriasis.

METHODS

This was a prospective cohort study in which response to systemic therapies was assessed using the Psoriasis Area and Severity Index (PASI). The CAGE (Cut down, Annoyed, Guilty, Eye opener) questionnaire was used to screen for alcohol misuse. A multivariable factional polynomial linear regression model was used to examine factors associated with change in PASI between baseline and follow-up.

RESULTS

The cohort comprised 266 patients (biologic cohort, n = 134; conventional systemic cohort, n = 132). For the entire cohort, the median (interquartile range) PASI improved from 13 (10·0-18·3) at baseline to 3 (1·0-7·5) during follow-up. A higher CAGE score [regression coefficient: 1·40, 95% confidence interval (CI) 0·04-2·77]; obesity (1·84, 95% CI 0·48-3·20); and receiving a conventional systemic rather than a biologic therapy (4·39, 95% CI 2·84-5·95) were significantly associated with poor response to treatment; whereas a higher baseline PASI (-0·83, 95% CI -0·92 to -0·74) was associated with a better response to treatment.

CONCLUSIONS

The poor response to therapy associated with alcohol misuse and obesity found in people with psoriasis calls for lifestyle behaviour change interventions and support as part of routine clinical care. Targeting interventions to prevent, detect and manage alcohol misuse among people with psoriasis is needed to minimize adverse health consequences and improve treatment response.

Examining Individual Differences in Wellbeing, Anxiety and Depression in Psoriasis Using a Clinically Modified Buddhist Psychological Model

Psoriasis patients can experience a range of psychosocial difficulties, which can lead to issues with wellbeing, anxiety and depression. Mindfulness-based interventions have positive impacts on these outcomes; however, there is a need to identify the mechanisms of action of such interventions. This study attempts to do so by examining individual differences in psoriasis patients' wellbeing, anxiety and depression using a clinically modified Buddhist psychological model (CBPM). Psoriasis patients (N = 285) and (N = 209) completed measures of each CBPM component at time 1 and 2. SEM analyses found that a direct and mediated effect of CBPM model was a good fit to the participant's data. This study suggests that non-attachment, aversion, acceptance and self-compassion could have a direct effect on the wellbeing, anxiety and depression of psoriasis patients and an indirect effect through reduced worry and rumination. This study provided preliminary evidence for the CBPM as being a useful explanatory framework of psoriasis patients' anxiety, depression and wellbeing.

Alcohol in Psoriasis-From Bench to Bedside

Alcohol affects the symptoms, compliance and comorbidities as well as the safety and efficacy of treatments in psoriatic patients. In this review, we aim to summarize and link clinical observations with a molecular background, such as signaling pathways at the cellular level and genetic variations, and to provide an overview of how this knowledge could influence our treatment selection and patient management.

Neuroimmune Mechanisms as Novel Treatment Targets for Substance Use Disorders and Associated Comorbidities

Recent studies examining the neurobiology of substance abuse have revealed a significant role of neuroimmune signaling as a mechanism through which drugs of abuse induce aberrant changes in synaptic plasticity and contribute to substance abuse-related behaviors. Immune signaling within the brain and the periphery critically regulates homeostasis of the nervous system. Perturbations in immune signaling can induce neuroinflammation or immunosuppression, which dysregulate nervous system function including neural processes associated with substance use disorders (SUDs). In this review, we discuss the literature that demonstrates a role of neuroimmune signaling in regulating learning, memory, and synaptic plasticity, emphasizing specific cytokine signaling within the central nervous system. We then highlight recent preclinical studies, within the last 5 years when possible, that have identified immune mechanisms within the brain and the periphery associated with addiction-related behaviors. Findings thus far underscore the need for future investigations into the clinical potential of immunopharmacology as a novel approach toward treating SUDs. Considering the high prevalence rate of comorbidities among those with SUDs, we also discuss neuroimmune mechanisms of common comorbidities associated with SUDs and highlight potentially novel treatment targets for these comorbid conditions. We argue that immunopharmacology represents a novel frontier in the development of new pharmacotherapies that promote long-term abstinence from drug use and minimize the detrimental impact of SUD comorbidities on patient health and treatment outcomes.

Comparison of Different Nutritional and Lifestyle Factors between Glaucoma Patients and an Age-Matched Normal Population

PURPOSE

To compare nutritional and lifestyle factors between glaucoma patients and an age-matched control group.

METHODS

One hundred and ninety (190) glaucoma patients were enrolled in this study. The control group comprised 97 age-matched participants. Data on physical activity, nicotine smoking, and several nutritional habits like coffee and alcohol consumption as well as high-salt and high-protein intake were collected using a standardised questionnaire.

RESULTS

Age and gender were not statistically significantly different between the groups. There was a tendency for higher physical activity in the glaucoma group in comparison to the control group (47.3 vs. 35.4%; p = 0.056). Statistically significantly more glaucoma patients were nonsmokers (n = 169; 89.4%) compared to the control group (n = 64; 66.7%; p = 0.001). Glaucoma patients were also more often teetotal compared to the control group (21.6% compared to 14.4%; p < 0.001). Similarly, more glaucoma patients drank larger amounts of coffee in comparison to the control group (p = 0.001). One hundred and seventy-six (96.7%) glaucoma patients and 88 (90.7%) control subjects had high-protein intake (p = 0.035). High-salt intake was significantly lower in the glaucoma group (69.3 vs. 73.2%; p = 0.018). Of the 190 glaucoma patients, 81 had early visual field impairments (MD > - 6 dB) and 109 patients had moderate (MD between - 6 dB and - 12 dB) to severe (MD < - 12 dB) visual field defects. The severity of visual field defects, whether early, moderate, or severe, had no statistically significant impact on lifestyle parameters.

CONCLUSION

Contrary to our original hypothesis that glaucoma patients would tend to follow an unhealthier lifestyle than the control group, the opposite was seen. Presumably, the cause of this healthier lifestyle is the desire to contribute positively through the course of the disease.

Association of Skin Psoriasis and Somatic Comorbidity With the Development of Psychiatric Illness in a Nationwide Swedish Study

Importance

Psoriasis is a complex systemic disease with skin involvement, somatic comorbidity, and psychiatric illness (PI). Although this view of psoriasis is widely accepted, potential synergies within this triad of symptoms have not been adequately investigated.

Objectives

To investigate the independent association of skin psoriasis and somatic comorbidity with the development of PI and to assess whether skin psoriasis and somatic comorbidity act synergistically to produce a risk of PI that is greater than the additive associations.

Design, Setting, and Participants

Participants were enrolled between January 2005 and December 2010, in this retrospective matched case-control study using secondary (ie, administrative), population-based registry data from Swedish patients in routine clinical care. The dates of analysis were March 2017 to December 2019. Participants were patients with skin psoriasis and control participants without psoriasis matched on age, sex, and municipality, who were all free of preexisting PI.

Exposures

Presence of skin psoriasis and somatic comorbidity (captured through the Charlson Comorbidity Index and the Elixhauser Comorbidity Index).

Main Outcomes and Measures

Risk of PI onset (composite of depression, anxiety, and suicidality) is shown using Kaplan-Meier curves stratified by the presence of skin psoriasis and somatic comorbidity. Adjusted associations of skin psoriasis and somatic comorbidity with the development of PI were analyzed using Cox proportional hazards regression models, including interactions to assess synergistic associations. The 3 components of PI were also assessed individually.

Results

A total of 93 239 patients with skin psoriasis (mean [SD] age, 54 [17] years; 47 475 men [51%]) and 1 387 495 control participants (mean [SD] age, 54 [16] years; 702 332 men [51%]) were included in the study. As expected, patients with skin psoriasis were more likely to have somatic comorbidity and PI than control participants. Compared with those without skin psoriasis or somatic comorbidity, patients with psoriasis without somatic comorbidity had a 1.32 times higher risk of PI onset (hazard ratio [HR], 1.32; 95% CI, 1.27-1.36; P < .001), whereas patients with psoriasis with somatic comorbidity had a 2.56 times higher risk of PI onset (HR, 2.56; 95% CI, 2.46-2.66; P < .001). No synergistic associations of skin psoriasis and somatic comorbidity with the development of PI were found (HR, 0.93; 95% CI, 0.81-1.04; P = .21).

Conclusions and Relevance

This study found that somatic comorbidity appeared to alter PI onset even more than skin psoriasis. The observed association of skin psoriasis and somatic comorbidity with the development of PI reinforces the need for proactive, holistic treatment of patients with psoriasis.

Treatment of psoriasis - unburdened by fear during SARS-CoV2 menace

In a matter of mere months, humanity was unexpectedly struck by the appearance of SARS-CoV-2, shifting our perception as medical practitioners regarding our day-to-day activity. One especially disconcerting change was patient addressability to medical facilities, as well as access to proper healthcare in various fields. As these changes occurred rapidly, dermatologists too had to adapt by means of teledermatology, giving us back the ability to reach, treat, and comfort our patients. Among the individuals requiring special dermatological attention are those suffering from psoriasis, especially considering that the biological therapies employed in treating this debilitating disease become questionable in the circumstance of the current pandemic. As more evidence surfaces concerning the pathophysiology of SARS-CoV-2, we become closer to understanding which therapies may interfere with its clearance, and which are actually safe to use. This review aims to answer the question, are biological therapies warranted in the treatment of psoriasis during the COVID-19 outbreak, or should they be discontinued?

Association Between the Mental Health of Patients With Psoriasis and Their Satisfaction With Physicians

Importance

How patients' mental health is associated with their satisfaction with physicians is rarely studied among adults with skin conditions.

Objective

To examine the association between mental health comorbidities in patients with psoriasis and their satisfaction with physicians.

Design, Setting, and Participants

This retrospective survey analysis used 14 years of nationally representative longitudinal data on adults in the United States with psoriasis from the 2004-2017 Medical Expenditure Panel Survey. Statistical analysis was performed from October 1, 2018, to December 1, 2019. Mental health comorbidities were measured by performance on the Kessler 6-Item Psychological Distress Scale (score range, 0-24, where a score ≥13 is considered an indicator of a serious mental illness and significant psychological distress) and the Patient Health Questionnaire 2 (score range, 0-6, where a score ≥3 is considered a positive screening result for a depressive disorder).

Main Outcomes and Measures

Patient satisfaction with physician, measured by the patient-physician communication composite score.

Results

A weighted total of 8 876 767 US adults with psoriasis (unweighted total, 652 patients) (weighted; 54% women; mean [SEM] age, 52.1 [0.7] years) were analyzed; 27% of adults had moderate or severe symptoms of psychological distress, and 21% had moderate or severe symptoms of depression. Patients with moderate or severe psychological distress symptoms were less satisfied with their clinicians compared with those with no or mild psychological distress symptoms (mean Kessler 6-Item Psychological Distress Scale scores for no or mild symptoms, 14.3 [95% CI, 14.2-14.4]; moderate symptoms, 13.2 [95% CI, 13.0-13.4]; and severe symptoms, 13.1 [95% CI, 12.5-13.7]; P < .001). In addition, compared with patients with no or mild psychological distress symptoms, patients with moderate psychological distress symptoms were 2.8 times more likely to report low patient satisfaction (adjusted odds ratio, 2.8 [95% CI, 1.5-4.9]; P = .001), and patients with severe psychological distress symptoms were 2.3 times more likely to report low patient satisfaction (adjusted odds ratio, 2.3 [95% CI, 1.1-4.7]; P = .03). Furthermore, patients with moderate or severe depression symptoms were less satisfied with their clinicians compared with those with no or mild depression symptoms (mean Patient Health Questionnaire 2 scores for no or mild symptoms, 14.3 [95% CI, 14.2-14.4]; moderate symptoms, 13.2 [95% CI, 12.9-13.6]; and severe symptoms, 13.0 [95% CI, 12.6-13.4]; P = .002). In addition, compared with patients with no or mild depression symptoms, patients with moderate depression symptoms were 4.6 times more likely to report low patient satisfaction (adjusted odds ratio, 4.6 [95% CI, 2.1-10.0]; P < .001).

Conclusions and Relevance

This study suggests that patients with greater psychological distress and depression report lower satisfaction with their clinicians than those without such mental health symptoms. Clinicians need to be adaptable and supportive when communicating with patients with mental health comorbidities. Evaluating clinician performance solely based on patient satisfaction can be problematic and incomplete.

Epidemiology of depression and anxiety in patients with psoriatic arthritis: A systematic review and meta-analysis

OBJECTIVE

To conduct a systematic review and meta-analysis of the prevalence, incidence, and medication treatment of depression and anxiety among patients with psoriatic arthritis (PsA).

METHODS

We searched Medline, Embase, Cochrane Database of Systematic Reviews, CINAHL and PsycINFO for full-length studies that: utilized an observational design; included patients with PsA with/without a comparator group; evaluated depression and/or anxiety as an outcome, comorbidity, or predictor of a health outcome; and reported relevant estimates. We pooled estimates using random effects models.

RESULTS

Of 683 titles identified in our search, 18 studies met inclusion criteria. The pooled prevalence proportion for depression based on 11 studies was 17% (95% confidence interval [CI], 13% to 21%). In addition, a meta-analysis of four studies comparing the prevalence of depression in patients with PsA to those without PsA yielded a pooled odds ratio (OR) of 1.68 (95% CI, 1.37 to 2.08). The incidence of depression in PsA patients compared to the general population yielded a pooled incidence rate of 21.27 (95% CI, 16.28 to 26.27) per 1,000 person-years and a pooled incidence rate ratio of 1.44 (95% CI, 1.20 to 1.73). The pooled prevalence proportion of anxiety based on seven studies was 19% (95% CI, 11% to 29%) and a meta-analysis of two studies comparing the prevalence of anxiety in patients with PsA to those without PsA yielded a pooled OR of 1.49 (95% CI, 1.39 to 1.59). Only a small proportion of patients, between 2.4% and 13.5%, were reported to be taking antidepressant or antianxiety medications.

CONCLUSIONS

We identified substantial prevalence of depression and anxiety as well as elevated incidence of depression among patients with PsA. These findings should raise awareness of the importance of mental health care in this population.

Does illness perception associate with disease symptoms in Behçet's disease?

This study aims to assess the relationship between illness perception and disease course and symptoms in Behçet disease (BD). One hundred ten consecutive BD patients (F/M 50/60, mean age 38.5 ± 9.88 years) and 57 patients with Psoriasis as a disease control group (F/M 28/29, mean age 48.12 ± 15.52) are included in this cross-sectional study. Illness perception is evaluated using a revised version of the Illness Perception Questionnaire (IPQ-R). In IPQ-R, the identity score reflecting the number of symptoms is higher in BD patients with musculoskeletal involvement than the others (6.77 ± 2.91 vs. 5.08 ± 3.3, respectively, p = 0.007). The consequences score for musculoskeletal involvement (19.52 ± 7.03) and timeline (acute/chronic) score for eye involvement (26.67 ± 4.32) are also higher compared to patients without them (16.37 ± 5.82 and 22.09 ± 8.68) (p = 0.011 and p = 0.038), reflecting negative beliefs about the illness. The score of psychological attribution is higher in patients with psoriasis than BD (p = 0.039), whereas the other subgroup scores are lower in patients with psoriasis compared to those of BD (p < 0.05). This study provides a patient's perspective in the disease management process of BD using the IPQ-R questionnaire. A patient's own personal beliefs and emotional responses to their symptoms might affect the outcome measures, especially with musculoskeletal symptoms and eye involvement in BD. However, psychological attribution is found to be a prominent issue in psoriasis.

Timing of quality of life improvements in psoriatic patients treated with different systemic therapies

Psoriasis impacts the quality of life (QoL) by disrupting overall health and social life. Thus, the use of a QoL evaluation item is crucial in assessing a therapeutic regimen. Also, faster improvements in QoL lead to better patient compliance, but very few studies compare psoriasis traditional and biologic therapies timing. To evaluate how much different systemic therapies improve disease severity and QoL, a retrospective analysis was performed on 56 patients. Subjects were administered different drugs and their vital statistics, psoriasis area severity index (PASI) and PSOdisk were collected at baseline and after 30 days. We found a moderate correlation between PASI and PSOdisk score with (r): .62. In terms of clinical scores improvement after 30 days, Ustekinumab turned out to be the fastest therapy available, while cyclosporine, among the systemic therapies available, appeared as highly competitive if not better than other biologic therapies.

Guselkumab improves work productivity in patients with moderate-to-severe psoriasis with or without depression and anxiety: results from the VOYAGE 2 comparator study versus adalimumab

Purpose: To evaluate the impact of guselkumab on work productivity, including absenteeism and presenteeism, in psoriasis patients with and without depression/anxiety.Methods: VOYAGE 2 is a randomized, double-blind, placebo-controlled, and comparator-controlled, phase 3 trial that compared guselkumab with adalimumab in patients with moderate-to-severe psoriasis. Absenteeism was evaluated among patients who reported that their skin prevented work/study based on the Dermatology Life Quality Index (DLQI) work/study domain (score = 3) at baseline. Presenteeism was assessed by summarizing mean changes in four Work Limitations Questionnaire (WLQ) domain scores at week 24. Analyses were compared between treatments and stratified by depression/anxiety status at baseline.Results: At week 24, 82.1% and 50.0% in the guselkumab and adalimumab groups, respectively, reported a DLQI work/study score = 0 (no effect of skin on work/study) (p < .001). Mean changes (improvements) were greater in guselkumab-treated versus adalimumab-treated patients in the work limitations domains of Physical Demands (-6.9 vs. -3.3, p < .05), Mental-Interpersonal (-6.3 vs. -3.2, p < .06), and Output Demands (-6.2 vs. -2.2, p < .05). Improvements were consistent in patients with and without depression/anxiety.Conclusions: Psoriasis patients treated with guselkumab had significantly better improvements in absenteeism and presenteeism compared with those treated with adalimumab, regardless of depression/anxiety status.

Association of Psoriasis with Psychiatric Hospitalization in United States Children and Adults

BACKGROUND

Psoriasis is associated with psychosocial distress. Little is known about the relationship between psoriasis and mental health (MH) emergencies.

OBJECTIVE

To examine the associations of psoriasis and MH hospitalizations in the USA.

METHODS

Data from the 2002-2012 National Inpatient Sample were analyzed, including an approximately 20% sample of all US hospitalizations (n = 87,053,155 children and adults).

RESULTS

Hospitalization for MH disorders occurred more commonly in those with psoriasis compared to those without psoriasis (4.04 vs. 2.21%). In multivariable logistic regression models, psoriasis was associated with higher odds of admission for any MH disorder overall (adjusted odds ratio [95% confidence interval]: 2.32 [2.24-2.41]), as well as 9 of the 15 MH-specific disorders examined. Associated MH disorders included: anxiety, schizophrenia, personality disorder, depression, substance use disorders, history of MH disorder, alcohol-related disorders, adjustment disorders, and cognitive disorders. Children with versus those without psoriasis were also more likely to have a primary hospitalization for any MH disorder (2.82 [2.24-3.56]). Psoriasis inpatients were also more likely to have a primary hospitalization for any MH disorder compared to those with alopecia areata (1.99 [1.45-2.74]) or hidradenitis suppurativa (3.97 [3.49-4.52]). Psoriasis patients hospitalized with any MH disorder had higher mean [95% confidence interval] cost of inpatient care (USD 11,004 [10,846-11,241] vs. 9,547 [8,730-10,364]; p < 0.0001) compared to those without psoriasis, with USD 1,610,860 excess costs annually, with the majority of the costs coming from depression and mood disorders.

CONCLUSIONS

Children and adults with psoriasis had increased hospitalization for multiple MH disorders, which were associated with a considerable financial burden.

Correlation Between Quality of Life and Depression Among Persons Suffering from Psoriasis

Introduction:

Chronic dermatitis is a major sociomedical issue still being marginalized due to generally accepted view that skin diseases are less of a health problem than is the case with diseases of other organs and organ systems for they are not life-threatening. Measurement of quality of life of persons suffering from psoriasis could become an important factor in assessing the success of treatment and modern aspect of integration of the diseased into the planning of therapeutic procedures, monitoring of their outcomes and improving the quality of treatment.

Aim:

To determine the quality of life and the degree of depression of persons with psoriasis, as well as to make a correlation between the two.

Patients and methods:

A descriptive and analytical study of cross-sectional character has been performed. The sample consisted of N = 56 respondents with medically verified diagnosis of psoriasis that was treated at the Clinic for Skin and Venereal Diseases of the Clinical Centre of the University of Sarajevo. Criteria for involvement of participants: respondents are to be over 18 years of age with verified medical diagnosis of psoriasis, and to voluntarily consent for inclusion in the research. The research instruments consisted of standardized questionnaires: the WHO-BREF Quality Questionnaire and the Beck Depression Inventory.

Results:

Median value of scores relating to quality of life of persons with psoriasis from our sample was highest in the domain of social interaction and amounted to 72 (51.50-81.00); the domain of physical health was 63 (39.50-75.00); the psychological condition was 63 (44.00-75.00); and the environmental domain was 63 (44.00-73.50). Depression of persons with psoriasis showed correlation with domains of quality of life. The depression proved correlated with the respondents’: physical health (rho = -0.793 p = 0.0001); psychological health (rho = -0.842 p = 0.0001); social interactions (rho = -0.598 p = 0.0001); as well as with attitude towards the environment (rho = -0.709 p = 0.0001). Gender, age, education, marital or employment status did not prove statistically significant for influencing occurrence of the depression.

Conclusion:

Given that median scores of all four domains of the quality of life of persons suffering from psoriasis were in the higher half of classification scale, the quality of their life can be considered as satisfactory. The degree of depression and the domain of quality of life are in negative correlation with psoriasis.

Comparison of mental health outcomes among adults with psoriasis on biologic versus oral therapies: a population-based study

PURPOSE

We sought to compare the impact of biologic versus oral therapies on mental health outcomes among adult U.S. residents with moderate-to-severe psoriasis.

METHODS

We performed a nationwide, cross-sectional study comparing 2,303,534 (weighted) adults with moderate-to-severe psoriasis on biologic versus oral therapies and their associated mental health outcomes using the 2003-2015 Medical Expenditure Panel Survey (MEPS). Mental health outcomes were measured with the Kessler 6 (K6), a validated measure of psychological distress, and Patient Health Questionnaire 2 (PHQ2), a screening tool for depression.

RESULTS

The mean K6 score for residents on biologic therapies was significantly lower than that of residents on oral therapies (2.72 [95% CI: 2.27-3.17] versus 3.70 [95% CI: 3.27-4.12]; p < .001). The mean PHQ2 score for residents on biologic therapies was also significantly lower than that of residents on oral therapies (0.540 [95% CI: 0.390-0.690] versus 0.890 [95% CI: 0.749-1.031]; p < .001). Based on adjusted multivariable linear regression models, biologic therapy was associated with significant reductions in K6 (p < .001) and PHQ2 (p = .016) scores compared to oral therapy.

CONCLUSIONS

Therapeutic choices for psoriasis impact mental health outcomes. Biologic therapy is associated with reductions in psychological distress and depression as compared to oral therapy in the U.S. adult moderate-to-severe psoriasis population.

Improvement of depressive symptoms in patients with moderate-to-severe psoriasis treated with ustekinumab: an open label trial validated using beck depression inventory, Hamilton depression rating scale measures and 18fluorodeoxyglucose (FDG) positron emission tomography (PET)

BACKGROUND

Psoriasis is a chronic skin disease associated with psychiatric co-morbidities, especially depression. Early detection of psychological vulnerability in patients with psoriasis seems to be of great clinical importance and significantly impacts the quality of life of the patients.

OBJECTIVES

We sought to clarify the association between psoriasis and depressive symptoms in patients with moderate-to-severe psoriasis, and to determine the risk factors for depressive symptoms and analyze the effect of ustekinumab on the symptoms. We also aimed to evaluate the changes in glucose metabolism using ¹⁸fluorodeoxyglucose (FDG) positron emission tomography (FDG-PET).

METHODS

Fifteen patients with moderate-to-severe psoriasis scheduled to be treated with ustekinumab were enrolled. At baseline and after achieving a 75% reduction in the Psoriasis Area and Severity Index (PASI) score (PASI75), all patients underwent a psychiatric interview and FDG-PET. Fifteen healthy volunteers were enrolled for comparison.

RESULTS

Patients with moderate-to-severe psoriasis were more depressed than those in the control group were (p < .05). The severity of psoriasis at baseline did not correlate with the depression symptoms. Treatment with ustekinumab significantly reduced the depressive symptoms, as verified using Beck Depression Inventory and Hamilton Depression Rating Scale psychiatric interviews (p < .05). However, FDG-PET of the brain showed no significant difference before and after PASI75 achievement using ustekinumab injection.

CONCLUSIONS

Patients with moderate-to-severe psoriasis are at an increased risk for depressive symptoms, and treatment with ustekinumab may be beneficial. FDG-PET does not reflect the changes in depressive symptoms in such patients.

Psoriasis Treatments: A Review of the Current Research Pipeline

Psoriasis treatment is aimed at suppressing skin lesions and preventing relapses. Although in the last decade biological therapies have revolutionized the pharmacologic treatment armamentarium for psoriasis, many patients are still inadequately controlled with currently available therapeutics. An advanced understanding of the immunopathogensis of psoriasis has led to development of new drugs that refine existing treatments or target novel molecular and immunologic pathways. Here we review the most promising topical, oral, and injectable psoriasis treatments in the research pipeline, including agents that target cytokines interleukin (IL)-12/23, tumor necrosis factor-α, IL-20, IL-17, IL-22, inhibitors of calcineurin, phosphodiesterase type 4, protein kinase C, Janus kinase, p38 kinase, purine nucleotide phosphorylase, adenosine receptor agonists, and recombinant chaperonin protein. These targeted therapeutics offer the potential for greater clinical efficacy and less toxicity than traditional agents. As the number of treatment options continues to expand, clinicians will have more diverse opportunities to help patients achieve better psoriasis control.

Epidemiology and Clinical Features of Adult Patients with Psoriasis in Malaysia: 10-Year Review from the Malaysian Psoriasis Registry (2007-2016)

Background

Psoriasis is a chronic inflammatory skin disease affecting 2-3% of the general population.

Aim

To evaluate the epidemiology and clinical characteristics of patients with psoriasis who seek treatment in outpatient dermatology clinics throughout hospitals in Malaysia.

Materials and Methods

Data were obtained from the Malaysian Psoriasis Registry (MPR). All patients (aged 18 and above) who were notified to the registry from July 2017 to December 2017 were included in this study.

Results

Among 15,794 patients, Malays were the most common (50.4%), followed by Chinese (21.4%), Indian (17.6%), and others (10.6%). The mean age onset of psoriasis for our study population was 35.14 ± 16.16 years. Male to female ratio was 1.3 : 1. 23.1% of patients had positive family history of psoriasis. The most common clinical presentation was chronic plaque psoriasis (85.1%), followed by guttate psoriasis (2.9%), erythrodermic psoriasis (1.7%), and pustular psoriasis (1.0%). Majority of our patients (76.6%) had a mild disease with BSA < 10%. 57.1% of patients had nail involvement, while arthropathy was seen in 13.7% of patients. Common triggers of the disease include stress (48.3%), sunlight (24.9%), and infection (9.1%). Comorbidities observed include obesity (24.3%), hypertension (25.6%), hyperlipidemia (18%), diabetes mellitus (17.2%), ischaemic heart disease (5.4%), and cerebrovascular disease (1.6%). The mean DLQI (Dermatology Life Quality Index) was 8.5 ± 6.6. One-third (33.1%) of the patients had a DLQI score of more than 10, while 14.2% of patients reported no effect at all.

Conclusion

Our study on the epidemiological data of adult patients with psoriasis in Malaysia showed a similar clinical profile and outcome when compared to international published studies on the epidemiology of psoriasis.

Determinants of quality of life and psychological status in adults with psoriasis

We investigated whether disease severity and clinical manifestations were associated with depression, anxiety, stress and quality of life in adults with psoriasis. Participants were recruited from a dermatology outpatient clinic at a teaching hospital. Information on sociodemographic characteristics, disease severity, presence of arthropathy and head involvement was specifically recorded. Disease severity was assessed using the Psoriasis Area and Severity Index (PASI). Quality of life and psychological symptoms were measured using the Dermatology Life Quality Index (DLQI) and the Depression Anxiety Stress Scale (DASS), respectively. One hundred individuals were recruited. Unadjusted analysis revealed that head involvement was associated with depression [odds ratio (OR) 8.509; 95% confidence interval (CI) 1.077-67.231] and anxiety (OR 6.46; 95% CI 1.401-29.858). Severe disease was associated with a poorer quality of life compared to mild disease (OR 3.750; 95% CI 1.330-10.577). Younger age was associated with an increased risk of depression [mean difference (MD) - 8.640; 95% CI - 16.390 to - 0.890], anxiety (MD - 11.553; 95% CI - 18.478 to- 4.628), stress (MD - 11.440; 95% CI - 19.252 to - 3.628) and severely impaired quality of life (MD - 12.338; 95% CI - 19.548 to - 5.127). Following adjustments for age and disease severity, anxiety, stress and depression remained associated with severely impaired quality of life.

Does message framing affect changes in behavioural intentions in people with psoriasis? A randomized exploratory study examining health risk communication

Message framing is important in health communication research to encourage behaviour change. Psoriasis, a long-term inflammatory skin condition, has additional comorbidities including high levels of anxiety and cardiovascular disease (CVD), making message framing particularly important. This experimental study aimed to: (1) identify whether health messages about psoriasis presented as either gain- or loss-framed were more effective for prompting changes in behavioural intentions (BI), (2) examine whether BI were driven by a desire to improve psoriasis or reduce CVD risk; (3) examine emotional reactions to message frame; and (4) examine predictors of BI. A two by two experiment examined the effects on BI of message frame (loss vs. gain) and message focus (psoriasis symptom reduction vs. CVD risk reduction). Participants with psoriasis (n = 217) were randomly allocated to one of four evidence-based health messages related to either smoking, alcohol, diet or physical activity, using an online questionnaire. BI was the primary outcome. Analysis of variance tests and hierarchical multiple regression analyses were conducted. A significant frame by focus interaction was found for BI to reduce alcohol intake (p = .023); loss-framed messages were more effective for CVD risk reduction information, whilst gain-framed messages were more effective for psoriasis symptom reduction information. Message framing effects were not found for BI for increased physical activity and improving diet. High CVD risk was a significant predictor  of increased BI for both alcohol reduction (β = .290, p < .01) and increased physical activity (β = -.231, p < .001). Message framing may be an important factor to consider depending on the health benefit emphasised (disease symptom reduction or CVD risk reduction) and patient-stated priorities. Condition-specific health messages in psoriasis populations may increase the likelihood of message effectiveness for alcohol reduction.

The impact of biologic agents on health-related quality of life outcomes in patients with psoriasis

INTRODUCTION

Psoriasis is a common, immune-mediated skin disease often associated with significant physical and psychosocial impairment. Antipsoriatic biologic agents offer patients unparalleled treatment potential in regard to greater skin clearance and overall improved quality of life. Evaluation of the therapeutic efficacy of biologic agents on the full psoriasis disease burden must account for their impact on both physical symptoms, as well as patient-reported, health-related quality of life (HRQoL) measurements. Areas covered: Results from numerous clinical trials demonstrate the significant clinical efficacy of biological agents targeting tumor necrosis factor-α (TNF-α) and the interleukin (IL)-12/23 and IL-17 immune pathways. However, relatively limited data is available evaluating their full effect on quality of life outcomes. This review will discuss the most relevant and up-to-date clinical data on HRQoL measurements related to treatment with these aforementioned biologic agents. Expert commentary: Patient-reported outcomes (i.e. Dermatology Life Quality Index) are being used with increasing frequency in clinical trials, and provide valuable information on the impact of psoriasis on numerous aspects of day-to-day living. These outcomes must also be incorporated in clinical practice, in addition to physical assessment of disease severity, treatment decisions, and therapeutic response in the psoriasis patient population.

Uncovering burden disparity: A comparative analysis of the impact of moderate-to-severe psoriasis and hidradenitis suppurativa

BACKGROUND

Psoriasis and hidradenitis suppurativa (HS) exhibit distinct clinical features, but no studies have directly compared the health-related quality of life (HRQoL) in patients with moderate-to-severe manifestations of these conditions.

OBJECTIVE

To determine which disease is associated with more severe HRQoL impairment.

METHODS

Weighted averages of each of the following baseline HRQoL measures were determined and compared between HS and psoriasis populations from 5 clinical trials: Visual Analog Scale (VAS) for pain, Total Work Productivity Impairment, Dermatology Life Quality Index; EuroQOL 5D VAS, and Short Form-36 Health Survey.

RESULTS

Compared with patients with psoriasis, patients with HS reported higher scores for VAS-pain (54.3 vs 36.1 [P < .0001]), Dermatology Life Quality Index (15.3 vs 11.3 [P < .0001]), EuroQOL 5D VAS (58.8 vs 50.8 [P < .0002]), and Total Work Productivity Impairment (35.4 vs 18.2). Patients with HS had lower Short Form-36 Health Survey scores than did patients with psoriasis (physical, 39.6 vs 49.0; mental, 41.5 vs 47.5 [both P < .0001]).

LIMITATIONS

This analysis was performed using published summary data rather than patient-level data, and weighted pooled averages were compared.

CONCLUSIONS

Patients with HS have a higher HRQoL burden than patients with psoriasis. This study clearly documents the needs of patients with HS and the potential impact of medical, scientific, and societal consensus for the development of more effective HS treatments.

Secukinumab sustains good efficacy and favourable safety in moderate-to-severe psoriasis after up to 3 years of treatment: results from a double-blind extension study

BACKGROUND

Secukinumab has demonstrated significant efficacy with a good safety profile through 1 year in plaque psoriasis. Given the chronic nature of this disease, long-term follow-up is needed to evaluate psoriasis therapies fully.

OBJECTIVES

To determine the long-term (3-year) efficacy and safety of secukinumab in moderate-to-severe psoriasis.

METHODS

Patients completing 52 weeks of secukinumab treatment in the SCULPTURE core study entered an extension in which they continued the same double-blind regimens. Dosing regimens included a fixed-interval schedule (FI; every 4 weeks) and retreatment as needed (RAN), in which patients were withdrawn from secukinumab and received placebo until the start of relapse, at which time secukinumab every 4 weeks was reinitiated. The study was registered with number NCT01640951.

RESULTS

In total 168 patients receiving secukinumab 300 mg FI and 172 receiving secukinumab 300 mg RAN entered the extension. Secukinumab 300 mg FI sustained high efficacy: at the end of year 3, the proportion of responders achieving ≥ 90% improvement in Psoriasis Area and Severity Index (PASI 90) was 63·8%, and of PASI 100 responders it was 42·6%. The mean absolute PASI remained low (2-4) from week 52 to week 152 with 300 mg FI, with approximately two-thirds of patients reporting no impact of skin disease on their lives (Dermatology Life Quality Index of 0 or 1). Improvements in overall and subscale scores on all quality-of-life instruments were well sustained. As in the core study, FI dosing was consistently more efficacious than RAN. No new safety signals were identified to year 3.

CONCLUSIONS

Secukinumab 300 mg FI sustained high responses and improved quality of life with no new safety concerns through 3 years.
