Early detection of comorbidity in psoriasis: recommendations of the National Conference on Healthcare in Psoriasis

Alcohol abuse and discretionary habits in psoriatic patients: impact on IL-17 and IL-23 inhibitor response

BACKGROUND

Alcohol abuse is correlated with the onset and worsening of psoriasis, but its effects, as for smoking, on biological therapies are still poorly investigated.

MATERIALS AND METHODS

This study aimed to determine the prevalence of alcohol abuse and other discretionary habits (such as smoking and sedentary lifestyle) in patients with psoriasis treated with topicals, conventional systemic and biologic therapies. The second objective is to investigate the impact of discretionary habits, focusing on alcohol abuse, on the response to biological therapy. To identify alcohol dependence, the CAGE questionnaire was distributed among patients of our clinic.

RESULTS

305 patients were included with 18% at high risk of alcohol abuse. Clinically, guttate psoriasis and psoriatic arthritis were more common in patients at higher risk of alcohol abuse. Furthermore, patients with an alcohol problem who started biological therapy reported a higher PASI than those who drank less. None of the considered variables seemed to correlate with discontinuation of medication or with lower achievement of the analyzed outcomes (PASI100, PASI90, and PASI≤3). There was a stronger association between alcohol dependence and patients receiving conventional therapy than with patients receiving biologics.

CONCLUSIONS

The efficacy of biologicals did not seem to be impacted by alcohol consumption, smoking, or sedentary lifestyle.

Discontinuation of Fumaric Acid Esters is Affected by Depressive Symptomatology: A Retrospective Analysis

Fumaric acid esters (FAEs) remain a widespread therapy option for moderate-to-severe psoriasis. However, drug survival of FAEs is limited by adverse events (AEs) or inadequate treatment response. Depressive disturbances are highly prevalent in psoriasis patients and are hypothesized to be associated with the reporting of AEs and therapy discontinuation. This study's aim was to analyze whether psoriasis patients with comorbid depressive symptomatology are more likely to discontinue treatment with FAEs due to AEs and/or inadequate treatment response. Data were retrospectively extracted from the records of patients starting therapy with FAEs in the Department of Dermatology, University Hospital Essen, Germany between 2017 and 2022, covering the first 52 weeks of treatment. Psoriasis severity and depressive symptomatology, as well as AEs and therapy discontinuation, were analyzed. Psoriasis patients (N = 95, 47.37% female) with depressive symptomatology (42.11%) were more likely to discontinue therapy due to patient-reported AEs, while the total number of reported AEs was not associated with depression. The results support the hypothesis that among psoriasis patients with depressive symptoms, the associated introspection and somatization may result in increased sensitivity for AEs and thus in quicker therapy discontinuation. In these patients, the occurrence of nocebo effects should be minimized, e.g. by special communication techniques.

Global prevalence of metabolic syndrome in patients with psoriasis in the past two decades: current evidence

Patients with psoriasis are at an increased risk of metabolic syndrome (MetS); however, a systematic analysis of its global prevalence has not been performed to date. Here, we performed a systematic review and meta-analysis to assess the prevalence of MetS among patients with psoriasis. We searched five databases from inception through September 2021 and used the Agency for Healthcare Research and Quality (AHRQ) and Newcastle-Ottawa Scale (NOS) tools to assess observational study quality. Stata SE 15.1 was used to perform the data analysis. Subgroup, meta-regression and sensitivity analyses were used to evaluate interstudy heterogeneity. Publication bias was evaluated using Egger's and Begg's linear tests. The global prevalence of MetS in patients with psoriasis was 32% (95% confidence interval [CI], 0.26-0.38). The prevalence in adults was 32% (95% CI, 0.29-0.36), while that in children and adolescents was 9% (95% CI, 0.00-0.18). Latin America had the highest prevalence of 47% (95% CI, 0.43-0.51), whereas North America had the lowest prevalence of 26% (95% CI, 0.16-0.37). Patients with psoriasis vulgaris (29%; 95% CI, 0.23-0.35) or severe psoriasis (37%; 95% CI, 0.27-0.46) had a higher prevalence of MetS than those with other psoriasis types. These findings suggest that MetS should be appropriately recognized and managed in patients with psoriasis. More population-based prospective observational studies are required to elucidate the mechanisms underlying the coexistence of MetS in patients with psoriasis.

Metabolic comorbidities of psoriasis (Review)

Psoriasis is a chronic inflammatory and immune-mediated condition, which is no longer considered as being limited to the skin, but may affect the entire body. Epidemiological studies have shown that certain disorders, including obesity, diabetes, liver abnormalities, elevated lipid levels in the blood and metabolic syndrome, may occur more frequently in patients with psoriasis compared with the general population. As psoriasis is a chronic disease, the frequently associated comorbidities must be identified early to ensure timely treatment and, possibly, their prevention. Comorbidities often manifest clinically 1-2 years after the onset of psoriasis and are commonly seen in patients with severe forms of the disease. The association between psoriasis and its comorbidities is not coincidental, but rather based on common pathophysiological mechanisms and risk factors that underlie the increased frequency of comorbidities in patients with psoriasis. The aim of the present review was to emphasize the important role of dermatologists in the early recognition of comorbidities in patients with psoriasis, with a focus on metabolic comorbidities, precisely because the dermatologists are usually the first medical contact due to the predominance of skin lesions. Therefore, these specialists have the responsibility to inform patients on the association between psoriasis and possible multiple comorbidities, devise prevention and treatment plans, or even redirect patients to other specialists.

Common Fundamentals of Psoriasis and Depression

Psoriasis is an inflammatory, immune-mediated disease that is frequently associated with psychological comorbidities such as depression. The stigma patients feel because of the appearance of their skin may contribute to the high psycho-social burden of psoriasis. However, there is emerging evidence that overlapping biological mechanisms are, to a substantial degree, responsible for the close interaction between psoriasis and depression. Increased proinflammatory mediators, such as C-reactive protein or interleukin-6, are present in both psoriasis and depression, indicating that inflammation may represent a pathophysiological link between the diseases. Anti-inflammatory biologic therapies treat the clinical manifestations of psoriasis, but might also play a significant role in reducing associated depressive symptoms in patients with psoriasis. Comparison between single studies focusing on the change in depressive symptoms in psoriasis is limited by inconsistency in the depression screening tools applied.

A brief screening tool for depression in psoriasis patients: The Two Questions Test in clinical practice

Patients suffering from chronic inflammatory diseases such as psoriasis are prone to develop depressive symptoms. However, within the time constraints of dermatological clinics, depressive symptoms in psoriasis patients are often overlooked and thus underdiagnosed. The Two Questions Test may serve as a quick screening tool for an initial assessment of depressive burden in these patients. We evaluated its usefulness in the clinical context analyzing the records of patients starting systemic treatment for psoriasis with a selective interleukin (IL)23- or IL17A-inhibitor. In a total sample of N = 139 patients, baseline Two Questions Test scores were analyzed together with measures of psoriatic and psychiatric symptoms. In addition, the development of the Two Questions Test scores over the course of the first 28 weeks of treatment was assessed. No association was found between the Two Questions Test scores and skin symptoms measured by the Psoriasis Area and Severity Index and the visibility of skin lesions. However, skin related quality of life analyzed with the Dermatology Life Quality Index was associated with the Two Questions Test scores. In addition, the longitudinal analysis revealed improvement in Two Questions Test outcomes over the course of patients' treatment. These results indicate the Two Questions Test's usefulness both as an initial screening tool of depressive symptoms, as well as in its use as a sensitive tool for the repeated assessment of depressive symptoms in psoriasis patients.

[Treatment of psoriasis with secukinumab : Practical guidance]

BACKGROUND

Moderate to severe plaque psoriasis can be treated effectively with immunomodulating biologicals such as the interleukin-17A inhibitor secukinumab. In practice, however, questions often arise as to how to proceed in special situations, such as infections, comorbidity, pregnancy, or surgery.

OBJECTIVES

To address frequent questions about the treatment of plaque psoriasis with secukinumab in a consensus document of German psoriasis experts that supplements current guidelines.

METHODS

In a virtual expert meeting in May 2020, practical aspects of the treatment of psoriasis were discussed based on the experience of the participants and on current literature. The results of this discussion were summarized in the present consensus document.

RESULTS

This article provides practical guidance on case history, documentation of previous therapies, severity of psoriasis, and comorbidities before starting therapy with secukinumab. For patients treated with secukinumab, the course of action in case of vaccinations, chronic or acute infections, surgical interventions, special manifestations of psoriasis, and comorbidities including history of cancer and autoimmune disorders is discussed. Questions regarding family planning and health policy regulations are also addressed.

DISCUSSION

The recommendations for the treatment of psoriasis with secukinumab summarized in this consensus document may contribute to achieve optimal therapy for patients and to improve their quality of life.

Screening for depression in psoriasis patients during a dermatological consultation: A first step towards treatment

BACKGROUND AND OBJECTIVES

Depression is a highly prevalent comorbidity in psoriatic patients. The aim of this prospective study was to follow up psoriasis patients at risk for depression and to evaluate individual pathways to mental health care and the efficacy of depression screening in a real-life setting.

PATIENTS AND METHODS

In this prospective multicenter study, 355 patients with psoriasis were screened for depressive symptoms with the revised Beck Depression Inventory (BDI-II). General practitioners of patients at risk for depression were asked for further evaluation. One year later, information on mental health care provision was gathered.

RESULTS

130 patients were screened positive for depressive symptoms, and 71 patients were followed-up (follow-up rate: 54.6 %). Psychiatric treatment was recommended for 28.2 % and accepted by 23.9 % of patients. Parameters of disease activity of psoriasis (PASI: 3.1, ∆: -1.7, P = 0.018), quality of life (Dermatology Life Quality Index [DLQI]: 6.5, ∆: -2.8, P = 0.005), and depressive symptoms (BDI-II: 13.2, ∆: -8.3, P < 0.001) improved significantly. Decrease of the BDI-II score was more pronounced in patients with higher PASI decrease.

CONCLUSIONS

Screening for depressive symptoms led to increased utilization of mental health care and improvement of psoriasis, depressive symptoms, and quality of life. Thus, such screening should be implemented in routine care to optimize patient management.

Biologics recommendations for patients with psoriasis: a critical appraisal of clinical practice guidelines for psoriasis

PURPOSE

This review article serves to assess the consistency of recommendations from guidelines on biologic agents for psoriasis, based on the quality evaluation of psoriasis Clinical Practice Guidelines (CPGs).

METHODS

We conducted a systematic literature search to identify CPGs that provide recommendations on diagnosis and treatment for psoriasis. Four reviewers performed a quality assessment of the included CPGs with the Appraisal of Guidelines Research and Evaluation II (AGREE II) Instrument.

RESULTS

A total of 51 sets of CPGs from 22 medical societies or separate working groups fulfilled the inclusion criteria. The overall quality of the eligible sets of guidelines was moderate to high, with an overall average score of 55%The highest domain scores were Score and Purpose (70%) and Clarity of Presentation (68%). A total of 95 biologic agent recommendations were extracted from the 18 recommended CPGs.Three biologic agents (Etanercept, Adalimumab, Ustekinumab) were recommended for pediatric patients. Three biologic agents (Adalimumab, Ustekinumab, Secukinumab) were recommended as first-line biologic agents for adults with psoriasis.

CONCLUSION

The overall methodological quality of CPGs for psoriasis is medium to high. More attention should be paid to applicability in guideline development. The recommendations and the basis for them among various sets guidelines were almost consistent.

[Screening for mental comorbidities in dermatology : Successful implementation of a screening for mental comorbidities in the field of inpatient dermatological treatment]

BACKGROUND

Anxiety and depression are common in the field of inpatient somatic treatment. Especially in dermatology in which the treatment of chronic diseases is very common and the risk of stigmatization by society is particularly high, mental disorders appear in every third patient. Dermatological diseases and mental disorders often negatively interact with each other leading to increased morbidity. Dermatological guidelines recommend early detection, but this is often not adequately done in practice.

MATERIALS AND METHODS

We present the implementation of an easy screening for mental comorbidities in the field of inpatient dermatological treatment by using a short questionnaire. This so-called Patient Health Questionnaire‑4 (PHQ-4) consists of four questions regarding anxiety disorders and depression. Upon reaching a certain number of points, a psychosomatic consult is automatically requested. As a result the patient's stress is relieved and the necessary holistic treatment becomes possible.

RESULTS

In 2019, 83% of inpatients in our clinic were screened using the PHQ‑4; 98 psychosomatic consults were performed.

CONCLUSION

Our findings so far have shown the benefit of the screening with a minimal investment of time. We recommend its comprehensive use in the field of inpatient dermatological treatment.

Skin and metabolic syndrome: A review of the possible associations

Metabolic syndrome (MeTS) is a well-known health-related problem with several end-organ damages and the resulted side effects such as rising in the blood glucose and lipid and blood pressure. Although MeTS might show several skin symptoms such as acanthosis nigricans, skin tags, acne, and androgenic alopecia, it could also be implicated in the pathophysiology of numerous dermatologic disorders. Furthermore, some dermatologic drugs might be implicated in the incidence or exacerbation of MeTS. Consequently, MeTS and skin problem could interfere closely with each other and each one could predispose the patient to the other one and vice versa. Remembering these close relationships help us to have better therapeutic choices regarding each inflammatory skin conditions. Moreover, some of the skin symptoms should be followed cautiously to define the underlying MeTS.

Content and value of rehabilitation in dermatology

The therapy of chronic skin diseases is challenging for both the dermatologist and the patient. Current standards of therapy and individual circumstances of the patient have to be considered. Furthermore, chronic skin diseases are often associated with comorbidities that require treatment adapted to the individual. Therefore, optimal education of the patient and a holistic concept of therapy are needed, in many cases in collaboration with various medical disciplines. In this case, rehabilitation provides an opportunity to address important aspects such as comorbidities, psychosocial burden and limitations at work, in addition to treating the underlying disease. This article describes the differences between acute and rehabilitation health care in dermatology, and illustrates the importance of rehabilitation in dermatology, based on examples of chronic inflammatory skin diseases, chronic pruritus and dermato-oncological diseases.

Metabolic Syndrome and Psoriasis: A Case-Control Study in Kabul, Afghanistan

BACKGROUND

Psoriasis is a chronic inflammatory disease that is not limited to the skin. Recently, numerous studies have shown a positive association between metabolic syndrome and psoriasis.

OBJECTIVE

The current study aimed to examine the association of metabolic syndrome with psoriasis in an Afghan population.

METHODS

This was a case- control study including 114 patients with psoriasis and 114 controls aged ≥18 years admitted to the dermatology department of Maiwand Teaching Hospital in Kabul, Afghanistan. Height, weight, blood pressure, and waist circumference were measured in all subjects. Blood glucose, triglyceride, cholesterol, and high-density lipoprotein cholesterol levels were tested following overnight fasting. The modified National Cholesterol Education Program - Adult Treatment Panel III criteria were used for the diagnosis of metabolic syndrome.

RESULTS

In total, 51.8% of the cases and 44.7% of the controls were male. The average age of participants was 33.4±13.1 years in the case group and 41.1±15.4 years in the control group. The average duration of disease for psoriasis was 4.2 years with 5.6 years SD. The average PASI was 10.8 with 5.1 SD. More than half of the cases (62.3%) had moderate to severe psoriasis and 37.7% had mild psoriasis. The prevalence of metabolic syndrome was higher among patients with psoriasis compared to controls (36.8% vs 21.1%) with OR of 2.18 (p=0.009). In addition, overweight/obesity was more prevalent among cases compared to controls (65.8% vs 41.2%) with OR of 2.74 (p<0.001), whereas the waist circumference was not significantly different between the two groups. Furthermore, the mean levels of total cholesterol, triglyceride, and fasting blood glucose were also higher among patients with psoriasis compared to controls.

CONCLUSION

The results of the study confirm the association between psoriasis and metabolic syndrome. Hence, screening psoriatic patients for metabolic syndrome should be considered.

A Belgian consensus on the definition of a treat-to-target outcome set in psoriasis management

OBJECTIVE

Treat-to-target (T2T) is an algorithm to reach a predefined outcome. Here, we define a T2T outcome for moderate-to-severe psoriasis vulgaris.

METHODS

Briefly, the study included a literature review, discussions with key opinion leaders, recruitment of additional dermatologists with experience in managing moderate-to-severe psoriasis, 3 eDelphi survey rounds and a patient focus group. Relevant topics were selected during discussions prior to the survey for the statements. Surveys were based on the eDelphi methodology for consensus-building using a series of statements. Consensus was defined as at least 80% of participants agreeing. A psoriasis patient focus group provided feedback on topic selection and outcome.

RESULTS

A total of 5 discussions were held, and 3 eDelphi rounds were conducted with an average of 19 participants per round. The T2T outcome was set assuming shared decision between patient and dermatologist, awareness and referral for comorbidities by the dermatologist and appropriate treatment adherence by the patient. We defined 'ideal' and 'acceptable' targets; the latter referring to conditions restricting certain drugs. The T2T outcome was multidimensional, including ≥ ΔPASI90/75 or PGA ≤ 1, itch VAS score ≤ 1, absence of disturbing lesions, DLQI ≤ 1/3, incapacity daily functioning VAS score ≤ 1, safety ≤ mild side-effects and full/mild tolerability of treatment for the ideal and acceptable target, respectively. Finally, time to achieve the T2T outcome was set at 12 weeks after initiation for all treatments. At all times, safety should not exceed the presence of mild side-effects.

CONCLUSION

With this novel T2T composite outcome for psoriasis, clinicians and patients can make shared decisions on the treatment goals they envisage, as a guidance for future treatment steps - leading to a tight control management of the disease.

Design, Antileishmanial Activity, and QSAR Studies of a Series of Piplartine Analogues

Piplartine is an alkamide found in different Piper species and possesses several biological activities, including antiparasitic properties. Thus, the aim of the present study was to evaluate a series of 32 synthetic piplartine analogues against the Leishmania amazonensis promastigote forms and establish the structure-activity relationship and 3D-QSAR of these compounds. The antileishmanial effect of the compounds was determined using the MTT method. Most compounds were found to be active against L. amazonensis. Among 32 assayed derivatives, compound (E)-(−)-bornyl 3-(3,4,5-trimethoxyphenyl)-acrylate exhibited the most potent antileishmanial activity (IC50 = 0.007 ± 0.008 μM, SI > 10), followed by benzyl 3,4,5-trimethoxybenzoate (IC50 = 0.025 ± 0.009 μM, SI > 3.205) and (E)-furfuryl 3-(3,4,5-trimethoxyphenyl)-acrylate (IC50 = 0.029 ± 0.007 μM, SI > 2.688). It was found that the rigid substituents contribute to increasing antiparasitic activity against L. amazonensis promastigotes. The presence of the unsaturated heterocyclic substituent in the phenylpropanoid chemical structure (furfuryl group) resulted in a bioactive derivative. Molecular simplification of benzyl 3,4,5-trimethoxybenzoate by omitting the spacer group contributed to the bioactivity of this compound. Furthermore, bornyl radical appears to be important for antileishmanial activity, since (E)-(−)-bornyl 3-(3,4,5-trimethoxyphenyl)-acrylate exhibited the most potent antileishmanial activity. These results show that some derivatives studied would be useful as prototype molecules for the planning of new derivatives with profile of antileishmanial drugs.

Psoriasis Severity-A Risk Factor of Insulin Resistance Independent of Metabolic Syndrome

Background: It is still debatable whether psoriasis increases cardiovascular risk indirectly since it is associated with metabolic syndrome or is an independent cardiovascular risk factor. The aim of this study was to evaluate psoriasis severity as an independent predictor of insulin resistance (IR) irrespective of the presence of metabolic syndrome (MetS). Methods: This was a case control study including 128 patients stratified into two groups: patients with psoriasis and metabolic syndrome vs. patients with psoriasis and no metabolic syndrome. MetS was diagnosed according to ATP III criteria with homeostatic model assessment of insulin resistance (HOMA-IR), as well as a homeostatic model assessment of beta cell function (HOMA-β) were calculated. Results: Compared to subjects without metabolic syndrome, patients with metabolic syndrome had a significantly higher Psoriasis Area Severity Index (PASI) values (p < 0.001). The strongest correlation was established for HOMA-IR and the PASI index (p < 0.001), even after adjustment for body mass index (BMI) in regression analysis model. In patients without MetS and severe forms of disease, the HOMA-IR and HOMA-β values were significantly higher compared to mild forms of disease (p < 0.001 for all) while in subjects with MetS no difference was established for HOMA-IR or HOMA-β based on disease severity. Conclusions: Psoriasis severity is an independent risk factor of HOMA-IR, the strongest association being present in the non-MetS group, who still had preserved beta cell function suggesting direct promotion of atherosclerosis via insulin resistance depending on the disease severity, but irrespective of the presence of metabolic syndrome.

Systemic Inflammation and Cardiovascular Comorbidity in Psoriasis Patients: Causes and Consequences

Psoriasis is a common inflammatory skin disease characterized by the appearance of red scaly plaques that can affect any part of the body. High prevalence, chronicity, disfiguration, disability, and associated comorbidity make it a challenge for clinicians of multiple specialties. Likewise, its complex pathogenesis, comprising inflammation, hyperproliferation, and angioneogenesis, intrigues numerous scientific disciplines, namely, immunology. From a clinical perspective, the severity of psoriasis is highlighted by its increased mortality, with cardiovascular diseases contributing the highest excess risk. From a scientific point of view, psoriasis has to be considered a systemic inflammatory condition, as blood biomarkers of inflammation are elevated and imaging techniques document sites of inflammation beyond the skin. While the association of psoriasis with cardiovascular diseases is now widely accepted, causes and consequences of this association are controversially discussed. This review comments on epidemiologic, genetic, and mechanistic studies that analyzed the relation between psoriasis and cardiovascular comorbidity. The hypothesis of psoriasis potentially being an independent cardiovascular risk factor, driving atherosclerosis via inflammation-induced endothelial dysfunction, will be discussed. Finally, consequences for the management of psoriasis with the objective to reduce the patients’ excess cardiovascular risk will be pointed out.

Multidisciplinary Management of Spondyloarthritis-Related Immune-Mediated Inflammatory Disease

Introduction

Immune-mediated inflammatory diseases (IMIDs) are chronic autoimmune conditions that share common pathophysiologic mechanisms. The optimal management of patients with IMIDs remains challenging because the coexistence of different conditions requires the intervention of several specialists. The aim of this study was to develop a series of statements defining overarching principles that guide the implementation of a multidisciplinary approach for the management of spondyloarthritis (SpA)-related IMIDs including SpA, psoriasis, psoriatic arthritis, Crohn’s disease, ulcerative colitis and uveitis.

Methods

A Delphi consensus-based approach was used to identify a core set of statements. The process included development of initial questions by a steering committee, an exhaustive search of the literature using complementary approaches to identify potential statements and two Delphi voting rounds for finalization of the statements.

Results

Consensus was achieved on the related nature of IMIDs, the existence of a high prevalence of multiple IMIDs in a single patient and the fact that a multidisciplinary approach can result in a more extensive evaluation and comprehensive approach to treatment. The goals of a multidisciplinary team should be to increase diagnosis of concomitant IMIDs, improve the decision-making process, and increase patient satisfaction and adherence. Early referral and diagnosis, early recognition of concomitant IMIDs and optimizing treatment to improve patient quality of life are some of the advantages of using multidisciplinary teams. To be effective, a multidisciplinary team should be equipped with the appropriate tools for diagnosis and follow-up, and at a minimum the multidisciplinary team should include a dermatologist, gastroenterologist and rheumatologist; providing psychologic support via a psychologist and involving an ophthalmologist, general practitioners and nurses in multidisciplinary care is also important.

Conclusion

The present Delphi consensus identified a set of overarching principles that may be useful for implementation of a multidisciplinary approach for the management of SpA-related IMIDs.

Metabolic syndrome and the skin: a more than superficial association. Reviewing the association between skin diseases and metabolic syndrome and a clinical decision algorithm for high risk patients

There is ongoing scientific interest regarding comorbidities associated with the metabolic syndrome (MeTS). MeTS comprises a combination of parameters that predispose individuals to the development of type 2 diabetes and cardiovascular disease (CVD). Three or more of the following criteria are necessary: fasting glucose > 110 mg/dl (5.6 mmol/l), hypertriglyceridemia > 150 mg/dl (1.7 mmol/l), HDL levels < 40 mg/dl (men)/< 50 mg/dl (women), blood pressure > 130/85 mmHg, waist circumference (values for Mediterranean populations > 94 cm (men)/> 89 cm (women). In this review we attempted to summarize relevant data by searching dermatological literature regarding associations between various skin conditions and MeTS. A multitude of studies was retrieved and a further goal of the present article is to present plausible mechanistic connections. The severity of skin conditions like psoriasis has been linked with MeTS. Parameters of MeTS like insulin resistance are present in patients with early onset androgenic alopecia, hidradenitis suppurativa acne and rosacea. Since MeTS can lead to CVD and type 2 diabetes early detection of patients would be very important. Also therapeutic intervention on MeTS could lead to improvement on the severity of skin conditions. This reciprocal relationship between skin diseases and MeTS in our opinion holds great interest for further investigation.

Evaluation of abdominal fat index by ultrasonography and its relationship with psoriasis and metabolic syndrome

Introduction

Accumulating evidence indicates that psoriasis is associated with obesity and metabolic syndrome. Psoriasis and obesity share similar inflammatory mediators, and obesity may potentiate some inflammatory cytokines seen in psoriasis. Body fat distribution, particularly visceral adipose tissue (VAT), is an important factor in metabolic syndrome and atherosclerotic diseases. An association has been demonstrated between psoriasis and abdominal VAT measured by computed tomography (CT).

Aim

To measure abdominal VAT noninvasively by ultrasonography (USG) in patients with psoriasis and investigated its relation to psoriasis and metabolic syndrome.

Material and methods

The study population consisted of 41 psoriasis patients and 41 control subjects matched for age, sex, and body mass index. The maximal preperitoneal fat thickness (Pmax) at the anterior surface of the liver and the minimal subcutaneous fat thickness (Smin) of the abdomen were measured by USG. The abdominal fat index (AFI = Pmax/Smin ratio) was calculated and the results were compared between groups.

Results

The rate of metabolic syndrome was significantly higher in psoriasis patients (p = 0.0018). The mean AFI was similar in both groups. AFI was not associated with psoriasis in subjects with metabolic syndrome (p = 0.495) or with Psoriasis Area and Severity Index (r = 0.123, p = 0.443).

Conclusions

This is the first study to evaluate abdominal VAT by USG. Computed tomography may be more reliable than USG, but its high cost and radiation exposure are major disadvantages. Further studies are required to determine the relationships between psoriasis and VAT.

Pediatric Psoriasis Comorbidity Screening Guidelines

Importance

Psoriasis is a complex inflammatory skin condition associated with serious medical comorbidities in adults, including obesity, hypertension, dyslipidemia, type 2 diabetes mellitus, psoriatic arthritis, nonalcoholic fatty liver disease, depression, anxiety, and decreased quality of life. Because psoriasis begins in childhood in almost one-third of patients, early identification of risk may be critical to minimizing effects on future health.

Objective

To develop the first set of guidelines for comorbidity screening for patients with pediatric psoriasis based on current evidence.

Evidence Review

A literature review was performed using PubMed from January 1999 through December 2015. Limiting the search to human studies published in English and removing reviews and editorials produced 153 relevant manuscripts. An expert panel in psoriasis, pediatric dermatology, pediatric rheumatology, pediatric gastroenterology, pediatric endocrinology, and adult and pediatric cardiology used the patient-centered Strength of Recommendation Taxonomy (SORT) method to evaluate and grade the quality of evidence.

Findings

Because of the limited number of pediatric studies published on these topics, the strength of the panel's recommendations is classified as SORT level C expert consensus recommendations. The majority of recommendations coincide with those endorsed by the American Academy of Pediatrics for the general pediatric patient but with added attention to signs and symptoms of arthritis, depression, and anxiety. The panel also identified key areas for further investigation.

Conclusions and Relevance

Patients with pediatric psoriasis should receive routine screening and identification of risk factors for associated comorbidities. These guidelines are relevant for all health care providers caring for patients with pediatric psoriasis, including primary care clinicians, dermatologists, and pediatric specialists. Because these are the first pediatric guidelines, re-review and refinement will be necessary as studies further detail, and possibly stratify, risk in affected children.

The German National Program on Psoriasis Health Care 2005-2015: results and experiences

In 2005, the first national psoriasis survey in Germany revealed large deficits in health care particularly in patients with moderate to severe disease. The consecutive goal was to improve health care for psoriasis countrywide. For this, a large-scale national program was initiated starting with a comprehensive analysis of structures and processes of care for psoriasis. Patient burden, economic impact and barriers to care were systematically analyzed. In order to optimize routine care, a S3 guideline, a set of outcomes measures and treatment goals, were developed. Implementation was enforced by the German Psoriasis Networks (PsoNet) connecting the most dedicated dermatologists. The annual National Conference on Health Care in Psoriasis established in 2009 consented National Health Care Goals in Psoriasis 2010-2015 and defined a set of quality indicators, which are monitored on a regular basis. Currently 28 regional networks including more than 800 dermatologists are active. Between 2005 and 2014 7 out of 8 quality indicators have markedly improved, and regional disparities were resolved. e.g., mean PASI (Psoriasis Area Severity Index) dropped from 11.4 to 8.1 and DLQI (Dermatology Life Quality Index) from 8.6 to 5.9. A decade of experience indicates that a coordinated nationwide psoriasis program based on goal orientation can contribute to better quality of care and optimized outcomes.

The role of hormones in the pathogenesis of psoriasis vulgaris

Psoriasis vulgaris is a chronic, common skin disease, which affects the patient’s quality of life to the highest degree. Several exogenous factors and endogenous hormonal changes may act as triggers for psoriasis.

The skin possesses a true endocrine system, which is very important in multiple systemic diseases. A number of conditions are associated with psoriasis, and its severity can also be influenced by hormones. Even though the sex hormones and prolactin have a major role in psoriasis pathogenicity, there are a lot of other hormones which can influence the psoriasis clinical manifestations: glucocorticoids, epinephrine, thyroid hormones, and insulin.
