The association between psoriasis and hypertension: a systematic review and meta-analysis of observational studies

Synergistic impact of psoriasis and hypertension on all-cause mortality risk: A prospective cohort study

BACKGROUND

The linkage between psoriasis and hypertension has been established through observational studies. Despite this, a comprehensive assessment of the combined effects of psoriasis and hypertension on all-cause mortality is lacking. The principal aim of the present study is to elucidate the synergistic impact of psoriasis and hypertension on mortality within a representative cohort of adults residing in the United States.

METHODS

The analysis was conducted on comprehensive datasets derived from the National Health and Nutrition Examination Study spanning two distinct periods: 2003-2006 and 2009-2014. The determination of psoriasis status relied on self-reported questionnaire data, whereas hypertension was characterized by parameters including systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg, self-reported physician diagnosis, or the use of antihypertensive medication. The assessment of the interplay between psoriasis and hypertension employed multivariable logistic regression analyses. Continuous monitoring of participants' vital status was conducted until December 31, 2019. A four-level variable amalgamating information on psoriasis and hypertension was established, and the evaluation of survival probability utilized the Kaplan-Meier curve alongside Cox regression analysis. Hazard ratios (HRs) and their associated 95% confidence intervals (CIs) were computed to scrutinize the correlation between psoriasis/hypertension and all-cause mortality.

RESULTS

In total, this study included 19,799 participants, among whom 554 had psoriasis and 7,692 had hypertension. The findings from the logistic regression analyses indicated a heightened risk of hypertension among individuals with psoriasis in comparison to those devoid of psoriasis. Throughout a median follow-up spanning 105 months, 1,845 participants experienced all-cause death. In comparison to individuals devoid of both hypertension and psoriasis, those with psoriasis alone exhibited an all-cause mortality HR of 0.73 (95% CI: 0.35-1.53), individuals with hypertension alone showed an HR of 1.78 (95% CI: 1.55-2.04), and those with both psoriasis and hypertension had an HR of 2.33 (95% CI: 1.60-3.40). In the course of a stratified analysis differentiating between the presence and absence of psoriasis, it was noted that hypertension correlated with an elevated risk of all-cause mortality in individuals lacking psoriasis (HR 1.77, 95% CI: 1.54-2.04). Notably, this association was further accentuated among individuals with psoriasis, revealing an increased HR of 3.23 (95% CI: 1.47-7.13).

CONCLUSIONS

The outcomes of our investigation demonstrated a noteworthy and positive association between psoriasis, hypertension, and all-cause mortality. These findings indicate that individuals who have both psoriasis and hypertension face an increased likelihood of mortality.

Managing the Patient with Psoriasis and Metabolic Comorbidities

Epidemiological data demonstrate strong associations between psoriasis and metabolic comorbidities, including obesity, hypertension, diabetes mellitus, dyslipidemia, and non-alcoholic fatty liver disease. The presence of metabolic comorbidities significantly influences the selection and effectiveness of pharmacological treatments. Some drugs should be prescribed with caution in patients with metabolic comorbidities because of an increased risk of adverse events, while others could have a reduced effectiveness. The aim of this narrative review is to highlight the challenges that healthcare professionals may face regarding the management of psoriasis in patients with metabolic comorbidities. In the first part of the article, the epidemiological association between psoriasis and metabolic comorbidities and their pathogenetic mechanisms is summarized. The second part describes the efficacy and safety profile of conventional and biologic drugs in patients with selected metabolic comorbidities including obesity, non-alcoholic fatty liver disease/hepatic steatosis, and diabetes. Finally, the role of pharmacological and non-pharmacological interventions, such as diet, alcohol abstinence, physical activity, and smoking avoidance is discussed. In conclusion, the choice of the best approach to manage patients with psoriasis with metabolic comorbidities should encompass both tailored pharmacological and individualized non-pharmacological interventions.

Unveiling the role of IL-17: Therapeutic insights and cardiovascular implications

Interleukin-17 (IL-17), a pivotal cytokine in immune regulation, has attracted significant attention in recent years due to its roles in various physiological and pathological processes. This review explores IL-17 in immunological context, emphasizing its structure, production, and signaling pathways. Specifically, we explore its involvement in inflammatory diseases and autoimmune diseases, with a notable focus on its emerging implications in cardiovascular system. Through an array of research insights, IL-17 displays multifaceted functions yet awaiting comprehensive discovery. Highlighting therapeutic avenues, we scrutinize the efficacy and clinical application of four marketed IL-17 mAbs along other targeted therapies, emphasizing their potential in immune-mediated disease management. Additionally, we discussed the novel IL-17D-CD93 axis, elucidating recent breakthroughs in their biological function and clinical implications, inviting prospects for transformative advancements in immunology and beyond.

Alcohol consumption and risk of psoriasis: Results from observational and genetic analyses in more than 100,000 individuals from the Danish general population

Background

Psoriasis is associated with high alcohol consumption, but the causality of this relationship is unclear.

Objective

We aimed to use a Mendelian randomization approach to investigate the causal effects of alcohol on incident psoriasis.

Methods

We included 102,655 adults from the prospective Copenhagen studies. All participants filled out a questionnaire on alcohol consumption, were physically examined, and had blood drawn for biochemical and genetic analyses. We created a genetic instrument based on the number of fast-metabolizing alleles in alcohol dehydrogenase 1B and alcohol dehydrogenase 1C, known to be associated with alcohol consumption, to test whether alcohol consumption was causally associated with psoriasis.

Results

Observationally, we found an increased risk of incident psoriasis among individuals with high alcohol consumption compared to those with low alcohol consumption with a hazard ratio of 1.30 (95% confidence interval 1.05-1.60) in the fully adjusted model. Using genetic data to predict alcohol consumption to avoid confounding and reverse causation, we found no association between number of fast-metabolizing alleles and risk of psoriasis.

Limitations

Alcohol consumption was self-reported and psoriasis was defined using the International Classification of Diseases 10th revision and 8th revision codes.

Conclusion

Alcohol consumption is observationally but not causally associated with incident psoriasis.

Hypertension and Cardiovascular Outcomes in Inflammatory and Autoimmune Diseases: A Systematic Review and Meta-analysis

PURPOSE

This review aimed to investigate the prevalence of hypertension and cardiovascular (CV) complications in various inflammatory and autoimmune diseases (IAD).

RECENT FINDINGS

Despite recent improvements in the management of IAD, patients with IAD still have an increased CV mortality and CV complications, mostly related to CV risk factors such as hypertension and inflammation. We systematically searched MEDLINE and EMBASE libraries for controlled studies involving hypertension and CV complications in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriasis including psoriatic arthritis (PsA), Sjogren's syndrome (SS), or antineutrophil cytoplasmic antibody-associated vasculitis (AAV) between January 2000 and March 2022. We extracted data on the prevalence of hypertension and CV complications. Then, random-effects meta-analyses and exploratory multivariate meta-regression were performed to explore factors related to the prevalence of hypertension. Of 2726 studies screened, 122 were selected for the meta-analysis. The prevalence of hypertension was higher among patients with IAD than controls, with an overall unadjusted odds ratio (OR) [95% confidence interval] of 1.67 [1.58-1.76] and an adjusted OR of 1.36 [1.24-1.50]. All diseases were found to be associated with increased risk of hypertension: SLE, adjusted OR 3.40 [1.93-6.00]; psoriasis, OR 1.32 [1.16-1.51]; PsA, OR 1.49 [1.15-1.94]; RA, OR 1.28 [1.04-1.58]; SS, OR 2.02 [1.19-3.44]. Age and female sex were significantly associated with hypertension in patients with IAD. The risk of CV complications was increased: ischemic heart disease, adjusted OR 1.38 [1.21-1.57]; cerebrovascular disease, OR 1.37 [1.03-1.81]; heart failure, OR 1.28 [1.05-1.55]; atherosclerotic plaques presence, OR 2.46 [1.84-3.29]. The prevalence of hypertension and CV complications is higher among patients with IAD. Screening and management of hypertension appears to be of paramount importance in these patients.

Cardiovascular Considerations and Implications for Treatment in Psoriasis: An Updated Review

Psoriasis, a prevalent chronic inflammatory skin disorder affecting 2-3% of the global population, has transcended its dermatological confines, revealing a profound association with cardiovascular diseases (CVD). This comprehensive review explores the intricate interplay between psoriasis and cardiovascular system, delving into genetic links, immune pathways, and adipose tissue dysfunction beyond conventional CVD risk factors. The pathophysiological connections unveil unique signatures, distinct from other inflammatory skin conditions, in particular psoriasis-specific genetic polymorphisms in IL-23 and TNF-α have consistently been linked to CVD. The review navigates the complex landscape of psoriasis treatments, addressing challenges and future directions in particular relevance to CVDs in psoriasis. Therapeutic interventions, including TNF inhibitors (TNFi), present promise in reducing cardiovascular risks, and methotrexate could constitute a favourable choice. Conversely, the relationship between IL-12/23 inhibitors and cardiovascular risk remains uncertain, while recent evidence indicates that Janus kinase inhibitors may not carry CVD risks. Emerging evidence supports the safety and efficacy of IL-17 and IL-23 inhibitors in patients with CVDs, hinting at evolving therapeutic paradigms. Lifestyle modifications, statins, and emerging therapies offer preventive strategies. Dedicated screening guidelines for CVD risk assessment in psoriasis are however lacking. Further, the impact of different disease phenotypes and treatment hierarchies in cardiovascular outcomes remains elusive, demanding ongoing research at the intersection of dermatology, rheumatology, and cardiology. In conclusion, unraveling the intricate connections between psoriasis and CVD provides a foundation for a holistic approach to patient care. Collaboration between specialties, advancements in screening methodologies, and a nuanced understanding of treatment impacts are essential for comprehensive cardiovascular risk management in individuals with psoriasis.

Impact of Biologic Therapy on Key Cardiovascular Risk Parameters in a Psoriatic Cohort-a Retrospective Review

BACKGROUND

Psoriasis is a risk factor for cardiovascular disease. Biologic agents have revolutionised psoriatic skin control. This study aims to assess the change in cardiovascular risk factors in a cohort of patients treated with 1 year of continuous biologic treatment.

METHODS

A retrospective medical record review was conducted of consecutive patients receiving biologic therapy for chronic plaque psoriasis in a single dermatology centre at a major tertiary hospital in Australia. The effect of biologic therapy on psoriasis was assessed using a psoriasis area severity index (PASI). Cardiovascular risk factors included systolic blood pressure (SBP), diastolic BP (DBP), heart rate (HR) and body mass index (BMI). Measurements at baseline and 1-year follow-up were compared using paired t-tests.

RESULTS

A total of 106 patients were reviewed with a median age of 44 years, and 63% of the patients were male. At baseline, mean BMI was 30 (SD 7), mean SBP was 129 (SD 17), mean DBP was 81 (SD 9) and mean HR was 82 (SD 14). Over 12 months, the PASI was reduced from 17.4 (SD 8.5) to 1.4 (SD 1.7, p < 0.001) indicating skin improvement. There was no significant difference from baseline in SBP (difference 2.3 mmHg, 95% CI - 1.4-5.9), DBP (0.6 mmHg, 95% CI - 1.2-2.5), BMI (difference - 0.1 kg/m2, 95% CI - 0.9-0.7) or HR (difference 1.3, 95% CI - 3.9-6.4).

CONCLUSION

In patients with psoriasis, markers of cardiovascular disease risk did not improve after 1 year of biologic therapy despite significant improvements in psoriasis skin severity.

Drug survival of biologics and non-biologics in patients affected by palmoplantar psoriasis: a "real-world", mono-center experience

BACKGROUND

Data on the treatment of palmoplantar psoriasis (PP) are very limited as these patients are often excluded from clinical trials. Moreover, this form of psoriasis is often resistant to treatment, making its clinical management complex.

METHODS

Primary endpoint was to evaluate the clinical and demographic characteristics and the drug survival of both biological and non-biological drugs in a population affected by PP. Secondary endpoint was to highlight any differences between the hyperkeratotic and pustular variant. We analyzed data from 233 psoriasis patients with palmoplantar involvement, with or without chronic plaque psoriasis. We performed a drug-survival analysis with the aid of Kaplan-Meier survival and a multivariate analysis to highlight the influence of certain variables on treatment persistence using a Cox regression model.

RESULTS

The drug-survival analysis revealed that biologic drugs compared to non-biologic drugs are associated with a higher persistence in treatment (59.73 vs. 43.56%); in particular, anti-IL23 drugs were found to be the drugs with the best drug-survival overall (67.94% of patients at 60 months are still on these drugs). Furthermore, our multivariate analysis shows that when compared with biological drugs, non-biological drugs are associated with an increased risk of treatment discontinuation (HR = 1.95 [95% CI: 1.41-2.68], P = 0.001).

CONCLUSIONS

Our study confirms the difficulty of treating PP and shows that biologic drugs are associated with longer persistence in treatment than non-biologics in both PP's variants, not because of their higher effectiveness but because of their better safety profile.

Predictive Performances of Blood-Count-Derived Inflammatory Markers for Liver Fibrosis Severity in Psoriasis Vulgaris

Psoriasis is an immune-mediated, chronic disorder that significantly alters patients' quality of life and predisposes them to a higher risk of comorbidities, including liver fibrosis. Various non-invasive tests (NITs) have been validated to assess liver fibrosis severity, while blood-count-derived inflammatory markers have been proven to be reliable in reflecting inflammatory status in psoriatic disease. The fibrosis-4 (FIB-4) index became part of the newest guideline for monitoring psoriasis patients undergoing systemic treatment. Patients with psoriasis vulgaris and fulfilling inclusion criteria were enrolled in this study, aiming to assess for the first time in the literature whether such inflammatory markers are useful in predicting liver fibrosis. Based on internationally validated FIB-4 index values, patients were divided into two study groups: a low risk of significant fibrosis (LR-SF) and a high risk of significant fibrosis (HR-SF). Patients from HR-SF were significantly older and had higher values of the monocyte-to-lymphocyte ratio (MLR) (p < 0.001), which further significantly correlated with fibrosis severity (p < 0.001). Platelet-to-lymphocyte ratio (PLR), systemic immune inflammation index (SII), platelet-to-white blood cell ratio (PWR), and aggregate index of systemic inflammations (AISI) significantly correlated negatively with liver fibrosis (p < 0.001). PWR proved to be the most reliable inflammatory predictor of fibrosis severity (AUC = 0.657). MLR, PWR, and AISI were independent inflammatory markers in multivariate analysis (p < 0.001), while the AST to platelet ratio index (APRI) and AST to ALT ratio (AAR) can be used as additional NITs for significant liver fibrosis (p < 0.001). In limited-resources settings, blood-count-derived inflammatory markers such as MLR, PWR, and AISI, respectively, and hepatic indexes APRI and AAR prove to be of particular help in predicting significant liver fibrosis.

The Association of Psoriasis, Diabetes Mellitus, and Hypertension: A Meta-Analysis

Psoriasis is a systemic disease affecting various organs; however, it is usually thought of as a skin disease. A multidisciplinary approach is needed for better outcomes. The current meta-analysis assessed the association between diabetes mellitus, high blood pressure, and psoriasis. We searched four databases, including Cochrane Library, PubMed, MEDLINE, and Google Scholar, for relevant articles using the following keywords: psoriasis, hypertension, high blood pressure, cardiovascular risk factors, and diabetes mellitus. The author's name, year, and country of publication, diabetes, and hypertension among patients with psoriasis and control subjects were collected and entered into a Microsoft Excel sheet. Out of 1209 articles retrieved, 903 articles remained after duplication removal. From the 82 full texts screened, only seven studies fulfilled the inclusion and exclusion criteria. Psoriasis was associated with diabetes and hypertension: odds ratio 1.38, 95% CI 1.17-1.64; P-value 0.0002, chi-square 224.93, and odds ratio 1.60, 95% CI 1.41-1.81, P-value 0.00001, chi-square 226.59, respectively. Substantial heterogeneity was observed (I2 for heterogeneity, 97%, P < 0.001). A broad approach is needed to address the associated comorbidities and select the appropriate therapeutic approach. Randomized controlled trials investigating the best drugs for the treatment of psoriasis and its associated cardiovascular risk factors are needed.

Genetic insights into the risk of metabolic syndrome and its components on psoriasis: A bidirectional Mendelian randomization

The role of metabolic syndrome (MetS) on psoriasis has been explored only in observational studies. We conducted this bidirectional Mendelian randomization (MR) to clarify the causal relationship between MetS and its components and psoriasis. The genetic instruments of MetS and its five components (waist circumference [WC], hypertension, fasting blood glucose [FBG], triglycerides [TG], and high-density lipoprotein cholesterol [HDL-C]) were obtained from public genome-wide association studies (GWAS). Outcome datasets for psoriasis were collected from the FinnGen Biobank Analysis Consortium. The main method was inverse variance weighting, complemented by sensitivity approaches to rectify potential pleiotropy. MetS, WC, and hypertension increase the risk of psoriasis (MetS, odd ratios [OR] = 1.17, 95% confidence interval [CI] 1.08-1.27, p = 1.23e-04; WC, OR = 1.65, 95% CI  1.42-1.93, p = 1.06e-10; hypertension, OR = 2.02, 95% CI 1.33-3.07, p = 0.0009). In the reverse analysis, no causal association between psoriasis and MetS and its five components was identified. We provide novel genetic evidence that MetS, WC, and hypertension are risk factors for the development of psoriasis. Early management of MetS and its components may be an effective strategy to decrease the risk of psoriasis.

Baseline Characteristics of Canadian Patients in the Psoriasis Longitudinal Assessment and Registry (PSOLAR)

BACKGROUND

The Psoriasis Longitudinal Assessment and Registry (PSOLAR) is a global, prospective, longitudinal, disease-based registry. It serves as a post-marketing safety commitment with a focus on patients with moderate to severe plaque psoriasis who are candidates for systemic therapy.

OBJECTIVES

To describe the baseline disease demographics and clinical characteristics of a Canadian subgroup of participants enrolled in PSOLAR.

METHODS

Baseline demographic/disease characteristics, medical histories, and previous psoriasis treatments for Canadian patients in PSOLAR were summarized using descriptive statistics.

RESULTS

There were 1896 patients analyzed in the Canadian subgroup at 37 clinical sites, accounting for 15.7% of the global PSOLAR population. Baseline disease and clinical characteristics were as expected for a moderate to severe psoriasis population and were generally similar to the global PSOLAR population. Two distinctions were noted in the Canadian subgroup versus those enrolled globally: a higher proportion of patients were overweight/obese (84.7% vs. 80.4%) and male (61.4% vs. 54.7%). In addition, the Canadian subgroup had numerically higher historical peak disease activity (PGA score 3.35 vs. 3.1) and longer disease duration (22.3 years vs. 17.5 years). Canadian PSOLAR patients reported a variety of comorbidities, including psoriatic arthritis (31.5%), hypertension (34.6%), hyperlipidemia (24.3%), mental illness (24.1%), and inflammatory bowel disease (1.6%).

CONCLUSION

The Canadian subgroup of PSOLAR patients was generally similar to those enrolled globally with respect to baseline disease demographics and clinical characteristics. Multiple comorbidities are noted in the Canadian subgroup, underscoring the need for a holistic approach to the treatment of psoriatic patients.

Subclinical high-resolution chest CT scan features in psoriasis

BACKGROUND

Although psoriasis is considered a systemic disease, no clear association has been established between psoriasis and lung diseases. This study aims to detect and describe subclinical pulmonary involvement in psoriasis patients with various degrees of cutaneous manifestations.

METHODS

Adult psoriasis patients with no known active pulmonary disease or respiratory symptoms were screened for subclinical pulmonary manifestations and possible parenchymal changes using high-resolution computed tomography (HRCT) scan of the chest. Patients were classified according to the severity of skin manifestations. The clinical characteristics and radiographic findings of these patients were evaluated.

RESULTS

Fifty-nine patients with psoriasis were included, among which 47 (79.7%) had abnormal HRCT scan features. Micronodules were the most common detected lung lesions (66.1%), followed by nonspecific interstitial changes (32.2%), including pleuro-parenchymal band/atelectasis, scarring, and focal ground-glass opacities. Other HRCT findings included emphysematous changes and calcified granulomas. Abnormal HRCT findings correlated with older age and duration of psoriasis but not with the severity of skin manifestations.

CONCLUSIONS

Micronodules and minor focal nonspecific interstitial changes were the most detected lung alterations in patients with psoriasis. These findings of the pilot study highlight a possible pulmonary involvement in patients with psoriasis. Larger multicenter studies are needed to clarify these findings further.

LIMITATIONS

A major limitation of the study, is the lack of a control group with similar radiologic findings of different conditions done in the same geographical region.

Psoriatic erythroderma: comparative patient profile and association with psoriatic arthritis

Background: Psoriatic erythroderma is rare and the most severe form of psoriasis characterized by involvement of 80-90% of body surface area. Aims: to compare clinical and demographic characteristics of patients with psoriasis, depending on presence of psoriatic erythroderma in medical history; to assess the association between psoriatic arthritis and a history of psoriatic erythroderma. Materials and methods: patients aged 18 years and older with a duration of psoriasis of 10 years, from the psoriasis patients registry were included. Comparison of continuous quantitative variables was performed using t-test or Mann-Whitney U-test. The 2 test or Fisher's exact test was used to compare qualitative binary variables. The odds ratio of psoriatic arthritis in patients with and without a history of psoriatic erythroderma was calculated, unadjusted and adjusted for other independent variables. Results: The number of patients included in the analysis was 1,870. A history of psoriatic erythroderma (PE) had 227 (12.1%) of them. There were no significant differences in patient age at inclusion to the registry (47.113.1 years vs. 47.713.3 years), and prevalence of PE among men and women (12.6% vs. 11. 4%). Higher prevalence of arterial hypertension (47.9% vs 32.7%), angina pectoris (6.4% vs. 1.9%), myocardial infarction (3. 2% vs. 1.0%), biliary dyskynesia (14.3% vs. 3.9%), fatty liver (12.2% vs. 7.7%), cholelithiasis (8. 6% vs. 3.6%), and toxic liver disease (2.2% vs. 0.5%) among patients with vs without history of PE was found. Psoriatic arthritis was diagnosed in 67.0% patients with a history of psoriatic erythroderma. The odds of having psoriatic arthritis in patients with a history of psoriatic erythroderma were 4 times higher than in patients without erythroderma: 4.043 [2.975-5.493]. When adjusted for sex, age, duration of psoriasis, and body mass index, the odds ratio and statistical significance were maintained: 4.064 [2.939-5.619]. Conclusions: compared to patients without PE those with a history of psoriatic erythroderma have a greater comorbidity burden: a higher prevalence of cardiovascular diseases, diseases of the liver and biliary tract. A significant association between psoriatic arthritis and a history of PE was established.

Vitamin D status in Psoriasis: impact and clinical correlations

Psoriasis is a continuing, periodic, immune‑mediated, fiery skin disease branded by hyper proliferation of epidermal keratinocytes and accompanying with inflammatory cellular infiltrate in both dermis and epidermis. Immunomodulation could be an important effect of vitamin D in Psoriasis. This case-control study was designed to measure serum 25-hydroxy vitamin D levels in patients with psoriasis and healthy controls and to find out clinical correlation, if any. Six hundred two (n = 602) subjects (285 cases and 317 controls) were taken for the study. Cases and controls were frequency matched with respect to age and gender. Various demographic and clinical details were taken using a questionnaire. Chemiluminescence Micro Particle Immunoassay was used to estimate serum 25-hydroxy vitamin D levels. The vitamin D deficiency in psoriasis patients was 60.0% vs. 17.5% in controls (P < 0.001) with mean vitamin D levels of 28.3 ± 13.9 ng/ml in psoriasis patient’s vs. 37.9 ± 9.7 ng/ml in controls. Vitamin D deficiency was found to be associated with psoriasis independently of gender, age, smoking status, family history, hypertension, chronic medication, nail changes, duration of symptoms and severity of disease. Vitamin D levels were seven times lower in patients with Psoriasis as compared to controls. Reduced vitamin D levels are related to duration and clinical severity of the disease. Early detection of vitamin D deficiency and timely intervention could lead to better clinical outcome and improved quality of life in psoriasis patients.

Psoriasis and Cardiometabolic Diseases: Shared Genetic and Molecular Pathways

A convincing deal of evidence supports the fact that severe psoriasis is associated with cardiovascular diseases. However, the precise underlying mechanisms linking psoriasis and cardiovascular diseases are not well defined. Psoriasis shares common pathophysiologic mechanisms with atherosclerosis and cardiovascular (CV) risk factors. In particular, polymorphism in the IL-23R and IL-23 genes, as well as other genes involved in lipid and fatty-acid metabolism, renin–angiotensin system and endothelial function, have been described in patients with psoriasis and with cardiovascular risk factors. Moreover, systemic inflammation in patients with psoriasis, including elevated serum proinflammatory cytokines (e.g., TNF-α, IL-17, and IL-23) may contribute to an increased risk of atherosclerosis, hypertension, alteration of serum lipid composition, and insulin resistance. The nonlinear and intricate interplay among various factors, impacting the molecular pathways in different cell types, probably contributes to the development of psoriasis and cardiovascular disease (CVD). Future research should, therefore, aim to fully unravel shared and differential molecular pathways underpinning the association between psoriasis and CVD.

The risk of organ-based comorbidities in psoriasis: a systematic review and meta-analysis

Background

The close relationship between psoriasis and concomitant diseases is widely accepted. However, a comprehensive analysis of organ-based comorbidities in psoriasis is still lacking.

Objective

The authors aimed to present the risk of organ-based comorbidities in psoriasis by comparing the general population.

Methods

The authors retrieved a search of Pubmed, EMBASE, and Cochrane databases for studies reporting organ-based comorbidities in psoriasis versus the general population. Observational studies that met the following criteria were assessed: 1) Psoriasis diagnosis; 2) Cardiovascular or kidney or liver or respiratory or cerebrovascular outcomes; 3) Comparison group of individuals without psoriasis. Pooled Relative Risks (pRRs) and 95% Confidence Intervals (CIs) were calculated by using the random-effect model.

Results

Fifteen observational studies with 216,348 psoriatic patients and 9,896,962 individuals from the general population were included. Psoriasis showed a greater risk of organ-based comorbidities. Compared to the general population, pRR for all organ-based comorbidities was 1.20 (95% CI 1.11‒1.31) in psoriasis, and pRR was lower in mild 0.61 (95% CI 0.46‒0.81) than in moderate/severe patients. pRR was 1.20 (95% CI 1.11‒1.30) for cardiovascular, 1.56 (95% CI 1.20‒2.04), and 1.75 (95% CI 1.33‒2.29) for cerebrovascular and liver diseases, respectively. pRR for coexisting renal and cardiovascular events was 1.09 (95% CI 1.01‒1.18). pRR for coexisting renal and cerebrovascular events was 1.28 (95% CI 0.99‒1.66). pRR for coexisting renal and liver diseases was 1.46 (95% CI 1.10‒1.94). pRR for coexisting cardiovascular and liver diseases was 1.41 (95% CI 1.11‒1.80).

Study limitations

There is heterogeneity.

Conclusion

Psoriasis has a higher risk of single and multiple organ-based comorbidities than the general population. The present study will further improve attention to psoriasis as a systemic inflammatory disease.

Cardiometabolic multimorbidity is common among patients with psoriasis and is associated with poorer outcomes compared to those without comorbidity

BACKGROUND

Associations between cardiometabolic multimorbidity and response to therapy in psoriasis are unknown.

OBJECTIVE

Determine the associations of multimorbidity with response to biologic treatment in psoriasis patients.

METHODS

CorEvitas Psoriasis Registry participants who initiated biologic therapy and had 6-months follow-up were stratified by 0, 1, 2+ comorbidities (diabetes, hypertension, hyperlipidemia). Adjusted odds ratios (95% CIs) were calculated overall and separately by biologic class (TNFi, IL-17i, IL-12/23i + IL-23i), to assess the likelihood of achieving response for the 1 and 2+ groups vs. 0.

RESULTS

Of 2,923 patients, 49.5%, 24.7% and 25.8% reported 0, 1 and 2+ comorbidities, respectively. Overall, likelihood of PASI75 was 18% (OR =0.82; 95%CI: 0.67, 1.00) and 23% (OR =0.77; 95%CI: 0.63, 0.96) lower in those with 1 and 2+ comorbidities, respectively, vs. 0. In those who initiated IL-17i, odds of PASI75 and PAS90 were 34% (OR =0.66; 95%CI: 0.48-0.91) and 35% (OR =0.65; 95%CI: 0.47-0.91) lower in the 2+ multimorbidity cohort. No significant associations were found among users of TNFi or IL-12/23i + IL-23i groups in the multimorbidity group.

LIMITATIONS

Patients may not be representative of all psoriasis patients.

CONCLUSION

Multimorbidity in psoriasis may decrease the likelihood of achieving treatment response to biologic therapy and should be considered when discussing treatment expectations with patients.

Psoriasis and Cardiovascular Diseases: An Immune-Mediated Cross Talk?

Psoriasis is a chronic immune-mediated inflammatory skin disease, characterized by well-demarcated scaly, erythematous, infiltrated plaques. The cutaneous-to-systemic expansion of the inflammation in psoriasis leads to the concept of “psoriatic march” or “inflammatory skin march”. Accordingly, psoriasis is thought to be a systemic inflammatory disease associated with numerous comorbidities. Indeed, it’s currently considered an independent risk factor for cardiovascular diseases. Here, we discuss the current knowledge on TNF-α and IL-23/IL-17 mediated pathways linking the psoriatic plaque to the cardiovascular compartment. We further argue the possible involvement of the endothelial compartment in the psoriatic plaque- cardiovascular system crosstalk.

Interleukin 17, the double-edged sword in atherosclerosis

Cardiovascular diseases, including atherosclerosis, are the number one cause of death worldwide. These diseases have taken the place of pneumonia and other infectious diseases in the epidemiological charts. Thus, their importance should not be underestimated. Atherosclerosis is an inflammatory disease. Therefore, immunological signaling molecules and immune cells carry out a central role in its etiology. One of these signaling molecules is interleukin (IL)-17. This relatively newly discovered signaling molecule might have a dual role as acting both pro-atherogenic and anti-atherogenic depending on the situation. The majority of articles have discussed IL-17 and its action in atherosclerosis, and it may be a new target for the treatment of patients with this disease. In this review, the immunological basis of atherosclerosis with an emphasis on the role of IL-17 and a brief explanation of the role of IL-17 on atherosclerogenic disorders will be discussed.

Psoriasis and metabolic syndrome: implications for the management and treatment of psoriasis

Psoriasis is a chronic systemic inflammatory disorder associated with several comorbidities in addition to the characteristic skin lesions. Metabolic syndrome (MetS) is the most frequent comorbidity in psoriasis and a risk factor for cardiovascular disease, a major cause of death among patients with psoriasis. Although the exact causal relationship between these two disorders is not fully established, the underlying pathophysiology linking psoriasis and MetS seems to involve overlapping genetic predispositions and inflammatory pathways. Dysregulation of the IL‐23/Th‐17 immune signalling pathway is central to both pathologies and may be key to promoting susceptibility to metabolic and cardiovascular diseases in individuals with and without psoriasis. Thus, biological treatments for psoriasis that interrupt these signals could both reduce the psoriatic inflammatory burden and also lessen the risk of developing atherosclerosis and cardiometabolic diseases. In support of this hypothesis, improvement of skin lesions was associated with improvement in vascular inflammation in recent imaging studies, demonstrating that the beneficial effect of biological agents goes beyond the skin and could help to prevent cardiovascular disease. This review will summarize current knowledge on underlying inflammatory mechanisms shared between psoriasis and MetS and discuss the most recent clinical evidence for the potential for psoriasis treatment to reduce cardiovascular risk.

Chronic Plaque Psoriasis in Poland: Disease Severity, Prevalence of Comorbidities, and Quality of Life

The epidemiology of psoriasis has not been widely assessed in Polish population so far. This study aimed to investigate psoriasis epidemiological situation by evaluating disease course and severity, management, comorbidities, environmental factors, and knowledge about this disorder among psoriatic patients in Poland. A cross-sectional cohort population-based study enrolled 1080 psoriatic patients and 1200 controls. The mean age of psoriasis onset was 27.6 years; 78.24% had type I psoriasis. Positive family history of psoriasis was reported in 44.81% of patients, whereas itch was reported in vast majority of patients (83.33%). Based on PASI score moderate psoriasis was the most common in studied group (mean 12.63 ± 9.33, range 0−67.2). The DLQI score (12.01 ± 7.41, range 0−30.0) indicated a very large effect of psoriasis on the quality of life. Hypertension was the most prevalent comorbidity (33.80%), followed by obesity (16.85%) and dyslipidemia (11.85%). Stress was the foremost cause of disease exacerbation (66.20%); however, infections (44.07%) and seasonal changes (45.09%) had also an impact on the course of psoriasis. Psoriatic patients were more often smokers (37.59%) vs. general population (27.50%; p < 0.0001). In conclusion, epidemiological studies help clinicians in better disease and patient understanding, which may translate into better management and patient compliance.

The Effects of Modified Intermittent Fasting in Psoriasis (MANGO): Protocol for a Two-Arm Pilot Randomized Controlled Open Cross-over Study

BACKGROUND

Psoriasis is a complex disease associated with multiple comorbidities, including metabolic syndrome and leaky gut syndrome. Dietary lifestyle interventions have been reported to affect the disease in terms of lesional severity. It remains unclear how diets affect these comorbidities and the general health in psoriasis patients. Modified intermittent fasting (MIF) on 2 nonconsecutive days has shown beneficial effects on metabolic parameters. A significant advantage of MIF over the currently investigated dietary changes is its feasibility.

OBJECTIVE

Here, we aim to study the effects of MIF on skin, gut, and metabolic health in psoriasis patients.

METHODS

A 2-arm pilot randomized controlled open cross-over study will be performed in 24 patients with psoriasis. Patients will be randomized 1:1 to either start with 12 weeks of MIF and go on a subsequent regular diet for another 12 weeks or start with 12 weeks of regular diet and do subsequent MIF for 12 weeks. The following parameters will be assessed: demographics, disease phenotype, medical and familial history, psoriasis severity, dermatology-specific and general quality of life, nutritional and physical habits, mental and intestinal health, intestinal and cutaneous integrity, inflammatory and metabolic markers, and satisfaction.

RESULTS

A total of 24 participants have been enrolled in the study. The final visit is foreseen for June 2021.

CONCLUSIONS

The aim is to uncover the effects of MIF on psoriasis severity and gut health integrity through clinical and molecular investigation. More precisely, we want to map the evolution of the different markers, such as psoriasis severity, permeability, and inflammation, in response to MIF as compared to a regular diet,. Understanding how dietary lifestyles can affect epithelial lineages, such as the skin and gut, will greatly improve our understanding of the development of psoriasis and may offer a nonpharmacological venue for treatments.

Chronic Inflammation as the Underlying Mechanism of the Development of Lung Diseases in Psoriasis: A Systematic Review

Psoriasis is a systemic inflammatory disease caused by dysfunctional interactions between the innate and adaptive immune responses. The systemic inflammation in psoriasis may be associated with the development of comorbidities, including lung diseases. In this review, we aimed to provide a summary of the evidence regarding the prevalence of lung diseases in patients with psoriasis and the potential underlying mechanisms. Twenty-three articles published between March 2010 and June 2021 were selected from 195 initially identified records. The findings are discussed in terms of the prevalence of asthma, chronic obstructive pulmonary disease, interstitial lung disease, obstructive sleep apnea, pulmonary hypertension, and sarcoidosis in psoriasis. A higher prevalence of lung diseases in psoriasis has been confirmed in asthma, chronic obstructive pulmonary disease, obstructive sleep apnea, and pulmonary hypertension. These conditions are important as they are previously unrecognized causes of morbidity and mortality in psoriasis. The development of lung diseases in patients with psoriasis can be explained by several mechanisms, including common risk factors, shared immune and molecular characteristics associated with chronic inflammation, as well as other mechanisms. Understanding the prevalence of lung diseases in psoriasis and their underlying mechanisms can help implement appropriate preventative and therapeutic strategies to address respiratory diseases in patients with psoriasis.

The difference of lipid profiles between psoriasis with arthritis and psoriasis without arthritis and sex-specific downregulation of methotrexate on the apolipoprotein B/apolipoprotein A-1 ratio

BACKGROUND

Methotrexate (MTX) has a protective effect against cardiovascular diseases (CVD), but the mechanism is unclear.

OBJECTIVE

To investigate the effect of MTX on lipid profiles and the difference between psoriasis without arthritis (PsO) and psoriatic arthritis (PsA).

METHODS

In this prospective study, we recruited 288 psoriatic patients (136 PsA and 152 PsO) who completed 12 weeks of MTX treatment. Total cholesterol (TC), triglycerides (TG), lipoprotein A [LP(a)], high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein (LDL), apolipoprotein A1 (ApoA1), and ApoB were measured.

RESULTS

Compared with sex- and age-matched healthy controls, psoriatic patients had significantly (p < 0.0001) higher levels of proatherogenic lipids and lower levels of anti-atherogenic lipids. PsA patients had a higher ApoB/ApoA1 ratio than PsO patients (p < 0.05). Stepwise regression analysis found a positive correlation between the inflammatory marker hCRP and the Psoriasis Area Severity Index (PASI), ApoB/ApoA1 ratio, BMI, and smoking. ApoB was positively associated with concomitant arthritis, diabetes, and hypertension. MTX decreased the levels of pro-atherogenic and anti-atherogenic lipids. However, a significant reduction of the ApoB/ApoA1 ratio by MTX was only observed in male patients.

CONCLUSION

PsA patients had a significantly higher percentage of concomitant disease than PsO. The decrease of MTX on CVD might be related with sex.

Hepatic steatosis as measured by the computed attenuation parameter predicts fibrosis in long-term methotrexate use

INTRODUCTION

To determine predictors of hepatic steatosis by the computed attenuation parameter (CAP) and fibrosis via transient elastography (TE) in persons on methotrexate (MTX) therapy with rheumatologic and dermatologic diseases.

METHODS

A single-centred retrospective cohort study was performed. Patients on >6 months of MTX for a rheumatologic or dermatologic disease who had undergone TE from January 2015 to September 2019 were included. Multivariate analysis was performed to determine predictors of steatosis and fibrosis.

RESULTS

A total of 172 patients on methotrexate were included. Psoriasis was the most frequent diagnosis (n = 55), followed by rheumatoid arthritis (n = 45) and psoriatic arthritis (n = 34). Steatosis (CAP ≥245 dB/m) was present in 69.8% of patients. Multivariate regression analysis revealed that diabetes mellitus (OR 10.47, 95% CI 1.42-75.35), hypertension (OR 5.15, 95% CI 1.75-15.38), and BMI ≥30 kg/m2 (OR 16.47, 95% CI 5.56-45.56) were predictors of steatosis (CAP ≥245 dB/m). Predictors of moderate to severe fibrosis (Metavir ≥F2 = TE ≥8.0 kPa) by multivariate regression analysis included moderate to severe steatosis (CAP ≥270 dB/m) (OR 8.36, 95% CI 1.88-37.14), diabetes mellitus (OR 2.85, 95% CI 1.09-7.48), hypertension (OR 5.4, 95% CI 2.23-13.00), dyslipidemia (OR 3.71, 95% CI 1.50-9.18), and moderate alcohol use (OR 3.06, 95% CI 1.2-7.49).

CONCLUSIONS

In patients on MTX for rheumatologic and dermatologic diseases, hepatic steatosis as measured by CAP was common and moderate to severe steatosis predicted moderate to severe fibrosis.

Antihypertensive drug use and psoriasis: A systematic review, meta- and network meta-analysis

AIMS

Diverse genetic and/or external factors may induce psoriasis. Drug exposure is 1 such prominent external factor; antihypertensive drugs are reportedly associated with psoriasis, but study results have been inconsistent. In this context, we investigated the associations between antihypertensive drugs and incidence if psoriasis via a systematic literature review and meta-analysis.

METHODS

Literature search in databases such as PubMed, Embase and Web of Science was conducted on 8 January 2021, and obtained data were pooled for meta- and network meta-analysis. Fixed- or random effect models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for evaluating the strength of the associations between antihypertensive drugs and psoriasis incidence. In addition to meta-analysis, Bayesian network meta-analysis was performed. ResultsThirteen eligible studies were included for meta-analysis with 6 378 116 individuals and 8 studies for network meta-analysis with 5 615 918 individuals. All antihypertensive drugs were significantly associated with psoriasis incidence. In a meta-analysis, the pooled ORs were 1.67 (95% CI: 1.31-2.13) for angiotensin-converting enzyme (ACE) inhibitors, 1.40 (95% CI: 1.20-1.63) for β-blockers, 1.53 (95% CI: 1.23-1.89) for calcium-channel blockers (CCBs), and 1.70 (95% CI: 1.40-2.06) for thiazide diuretics. For the comparative risks of psoriasis among antihypertensive drugs in the network meta-analysis, ORs were 2.09 (95% CI: 1.39-3.18) for ACE inhibitors, 1.35 (95% CI: 0.99-1.91) for BBs, 1.53 (95% CI: 1.07-2.24) for CCBs and 1.80 (95% CI: 1.23-2.66) for thiazide diuretics.

CONCLUSION

This study confirmed the associations between antihypertensive drugs and psoriasis; ACE inhibitors, BBs, CCBs and thiazide diuretics increased the risk of psoriasis. Therefore, antihypertensive drug users should be carefully monitored for psoriasis.

Occult Blood in Feces Is Associated with Increased Risk of Psoriasis

BACKGROUND

The fecal immunochemistry test (FIT) has been proposed as a surrogate marker of intestinal inflammation. Psoriasis is a chronic inflammatory skin disease that is linked to underlying systemic inflammatory conditions, including inflammatory bowel disease.

METHODS

We investigated the association between occult blood in feces and the risk of psoriasis using data from the National Health Insurance System. This study was conducted involving 1,395,147 individuals who underwent health examinations from January 2009 to December 2012 and were followed up until the end of 2017.

RESULTS

The incidence of psoriasis (per 1,000 person-years) was 3.76 versus 4.14 (FIT-negative versus FIT-positive group) during a median follow-up of 6.68 years. In the multivariable-adjusted model, the hazard ratios for psoriasis were 1.03 for one positive FIT result, 1.12 for two positive FIT results, and 1.34 for three positive FIT results compared with negative FIT results.

CONCLUSION

The risk of psoriasis was significantly increased in patients with positive FIT results compared to the FIT-negative population.

Impact of Interleukin-17 Inhibitor Therapy on Arterial Intima-media Thickness among Severe Psoriatic Patients

BACKGROUND

Psoriasis is frequently accompanied by cardiovascular diseases based on the shared immunopathogenic pathway. Authors determined the effect of interleukin (IL)-17 inhibitor therapy on arterial intima-media thickness (IMT) among severe psoriatic patients.

METHODS

Thirty-one severe psoriatic patients were enrolled. Twenty received secukinumab and 11 received ixekizumab. Before treatment initiation and after 6 months, the carotid-brachial-femoral IMT, the Psoriasis Area Severity Index (PASI), the Dermatology Life Quality of Index (DLQI) and the EuroQol Visual Analogue Scale (EQ VAS) were evaluated.

RESULTS

After 6 months, significant ameliorations were observed in PASI (p < 0.001) from 18 to 0, in DLQI (p < 0.001) from 17 to 0, in EQ VAS (p < 0.001) from 60 to 90, in right carotid IMT (p < 0.001) from 1.1 mm to 0.8 mm, in left carotid IMT (p < 0.001) from 1.1 mm to 0.7 mm, in right brachial IMT (p < 0.001) from 0.75 mm to 0.6 mm, in left brachial IMT (p < 0.001) from 0.8 mm to 0.5 mm, in right femoral IMT (p < 0.001) from 0.9 mm to 0.7 mm and in left femoral IMT (p < 0.001) from 0.8 mm to 0.7 mm.

CONCLUSIONS

By reducing the inflammation of the vascular wall, anti-IL-17 therapy may have a beneficial long-term effect on cardiovascular complications of systemic inflammation.

Cardiovascular disease prevention in individuals with underlying chronic inflammatory disease

PURPOSE OF REVIEW

Patients with chronic inflammatory disease have an increased risk of cardiovascular disease. This article reviews the current evidence of cardiovascular prevention in three common systemic inflammatory disorders (SIDs): psoriasis, rheumatoid arthritis, and systemic lupus erythematosus.

RECENT FINDINGS

General population cardiovascular risk assessment tools currently underestimate cardiovascular risk and disease-specific risk assessment tools are an area of active investigation. A disease-specific cardiovascular risk estimator has not been shown to more accurately predict risk compared with the current guidelines. Rheumatoid arthritis-specific risk estimators have been shown to better predict cardiovascular risk in some cohorts and not others. Systemic lupus erythematosus-specific scores have also been proposed and require further validation, whereas psoriasis is an open area of active investigation. The current role of universal prevention treatment with statin therapy in patients with SID remains unclear. Aggressive risk factor modification and control of disease activity are important interventions to reduce cardiovascular risk.

SUMMARY

A comprehensive approach that includes cardiovascular risk factor modification, control of systemic inflammation, and increased patient and physician awareness is needed in cardiovascular prevention of chronic inflammation. Clinical trials are currently underway to test whether disease-specific anti-inflammatory therapies will reduce cardiovascular risk.

Effects of tobacco and vaping on the skin

Cigarette and electronic cigarette use are significant public health concerns across the United States. Tobacco use remains the single most preventable cause of morbidity and mortality in the world. Electronic cigarettes initially emerged as a better alternative to conventional cigarettes and for promoting smoking cessation; however, current evidence reveals similar deleterious health implications caused by both products on almost all organ systems, including the skin. Recognition of the cutaneous manifestations associated with cigarette and electronic cigarette use is essential for dermatologists in current clinical practice. Dermatologists play a vital role in educating and counseling patients on smoking cessation. We specifically highlight the cutaneous consequences of conventional cigarette smoking and electronic cigarettes on dermatologic disease.

Psoriasis and Cardiovascular Disease: Novel Mechanisms and Evolving Therapeutics

PURPOSE OF REVIEW

Psoriasis is a chronic inflammatory skin condition that is associated with increased cardiovascular risk compared to those without psoriasis. This review will cover emerging mechanisms of cardiovascular risk, key pathways targeted with biologic therapies, and the current evidence on therapies to modulate this risk in patients with psoriasis.

RECENT FINDINGS

Recent scientific work has highlighted mechanisms that contribute to this enhanced risk, including the role of vascular endothelial dysfunction, platelet activation, dyslipidemia, and increased cardiometabolic comorbidities. Newer biologic and targeted synthetic therapies have transformed psoriasis treatment with high rates of clinical remission and durable skin disease control now possible. Epidemiological evidence suggests that many of these therapies may lower cardiovascular risk in psoriasis, although prospective interventional data is lacking (or mixed). Recently, caution has also been raised that some treatments may negatively affect cardiovascular risk. Overall, the current data suggests a positive or neutral ability to reduce cardiovascular risk for TNF, IL-17A, and IL-12/23p40 inhibitors, but current evidence remains conflicting for anti-IL-23/p19 and JAK inhibitors. More studies that include prospective cohorts, larger number of patients, treatment duration, and validated surrogate outcomes are needed to better evaluate the role of biologic therapies on cardiovascular risk in psoriasis.

A transcriptome-wide association study identifies novel susceptibility genes for psoriasis

Although more than 80 psoriasis genetic risk loci have been reported through genome-wide association studies (GWASs), the genetic mechanism of psoriasis remains unclear. To identify novel candidate genes associated with psoriasis and reveal the potential effects of genetic factors in the development of psoriasis, we conducted a transcriptome-wide association study (TWAS) based on summary statistics from GWAS of psoriasis (5175 cases and 447 089 controls) and gene expression levels from six tissues datasets (blood and skin). We identified 11 conditionally independent genes for psoriasis after Bonferroni corrections, such as the most significant genes UBLCP1 (PYFS = 2.98 × 10-16), and LCE3C (PSNSE = 9.72 × 10-12, PSSE = 6.24 × 10-12). The omnibus test identified additional 5 genes associated with psoriasis via the joint association model from multiple reference tissues. Among the 16 identified genes, 5 genes (CTSW, E1F1AD, KLRC3, FIBP, and EFEMP2) were regarded as novel genes for psoriasis. We evaluated the 16 candidate genes by querying public databases and identified 11 differentially expressed genes and 8 genes proved by the knockout mice models. Through GO enrichment analyses, we found that TWAS genes were enriched in the known GO terms associated with skin development, such as cornified envelope (P = 4.80 × 10-8) and peptide cross-linking (P = 1.50 × 10-7). Taken together, our results detected multiple novel candidate genes for psoriasis, providing clues for understanding the genetic mechanism of psoriasis.

Association between Atopic Dermatitis and Hypertension: A Systematic Review and Meta-Analysis

BACKGROUND

Previous studies found conflicting results about the association of atopic dermatitis (AD) with hypertension.

OBJECTIVES

Determine whether AD and AD severity are associated with hypertension.

METHODS

A systematic review was performed of published studies in MEDLINE, EMBASE, Scopus, Web of Science, and GREAT databases. At least 2 reviewers conducted title/abstract, full-text review, and data extraction. Quality of evidence was assessed using the Newcastle-Ottawa Scale.

RESULTS

Fifty-one studies met inclusion criteria; 19 had sufficient data for meta-analysis. AD was associated with higher odds of hypertension compared to healthy controls (increased in 9 of 16 studies; pooled prevalence: 16.4% vs 13.8%; random-effects regression, pooled unadjusted odds ratio [OR][95% confidence interval <CI95>]: 1.16 [1.04-1.30]), but lower odds of hypertension compared to psoriasis (decreased in 5 of 8 studies; 15.4% vs 24.8%; 0.53 [0.37-0.76]). In particular, moderate-severe AD were associated with hypertension compared to healthy controls (increased in 4 of 6 studies; 24.9% vs 14.7%; 2.33 [1.10-4.94]). Hypertension was commonly reported as an adverse-event secondary to AD treatments, particularly systemic cyclosporine A. Limitations include lack of longitudinal studies or individual-level data and potential confounding.

CONCLUSIONS

AD, particularly moderate-to-severe disease, was associated with increased hypertension compared to healthy controls, but lower odds than psoriasis.

microRNAs involved in psoriasis and cardiovascular diseases

Psoriasis is a chronic inflammatory disease involving the skin. Both genetic and environmental factors play a pathogenic role in psoriasis and contribute to the severity of the disease. Psoriasis, in fact, has been associated with different comorbidities such as diabetes, metabolic syndrome, gastrointestinal or kidney diseases, cardiovascular disease (CVD), and cerebrovascular diseases (CeVD). Indeed, life expectancy in severe psoriasis is reduced by up to 5 years due to CVD and CeVD. Moreover, patients with severe psoriasis have a higher prevalence of traditional cardiovascular (CV) risk factors, including dyslipidemia, diabetes, smoking, and hypertension. Further, systemic inflammation is associated with oxidative stress increase and induces endothelial damage and atherosclerosis progression. Different miRNA have been already described in psoriasis, both in the skin tissues and in the blood flow, to play a role in the progression of disease. In this review, we will summarize and discuss the most important miRNAs that play a role in psoriasis and are also linked to CVD.

Association of Metabolic Comorbidities with Pediatric Psoriasis: A Systematic Review and Meta-Analysis

Background

An evident relationship has been shown between psoriasis and metabolic comorbidities. However, the results in pediatric psoriasis vary from study to study, and no meta-analysis exists on the association of metabolic comorbidities with pediatric psoriasis.

Objective

To evaluate the association between psoriasis and metabolic comorbidities in pediatric patients.

Methods

We searched articles published in PubMed, EMBASE, and Cochrane Library databases from inception to April 30, 2019. All observational studies reporting the prevalence of obesity or metabolic comorbidities in pediatric patients with psoriasis were included.

Results

The meta-analysis included 16 unique studies meeting the inclusion criteria. The pooled odds ratios in pediatric patients with psoriasis was 2.40 (95% confidence interval [CI], 1.60~3.59) for obesity (13 studies), 2.73 (95% CI, 1.79~4.17) for hypertension (8 studies), 2.01 (95% CI, 1.09~3.73) for diabetes mellitus (8 studies), 1.67 (95% CI, 1.42~1.97) for dyslipidemia (7 studies), and 7.49 (95% CI, 1.86~30.07) for metabolic syndrome (4 studies).

Conclusion

Pediatric patients with psoriasis showed a significantly higher prevalence of obesity, hypertension, diabetes, dyslipidemia, and metabolic syndrome. Adequate monitoring and timely management of metabolic comorbidities should be considered in these patients.

Selenium nanoparticles produce a beneficial effect in psoriasis by reducing epidermal hyperproliferation and inflammation

Background

Psoriasis is a chronic autoimmune skin disease characterized by hyperproliferation of keratinocytes. Wide treatment options used to treat psoriasis is associated with various adverse effects. To overcome this nanoformulation is prepared. Selenium is an essential trace element and plays major role in oxidation reduction system. Toxicity and stability limits the applications of selenium. Toxicity can be reduced and stabilized upon preparation into nanoparticles.

Results

Selenium nanoparticles (SeNPs) exhibit potent apoptosis through the generation of reactive oxygen species (ROS) with cell cycle arrest. SeNPs topical gel application produced significant attenuation of psoriatic severity with the abrogation of acanthosis and splenomegaly. SeNPs reduced the phosphorylation and expressions of MAPKs, STAT3, GSK-3β, Akt along with PCNA, Ki67, and cyclin-D1.

Conclusion

SeNPs inhibit various inflammation and proliferation mediated pathways and could be an ideal candidate for psoriasis therapy.

Materials and methods

SeNPs were characterized and various techniques were used to determine apoptosis and other molecular mechanisms. In vivo studies were performed by inducing psoriasis with imiquimod (IMQ). SeNPs were administered via topical route.

Graphic Abstract

Psoriasis: Comorbidities

Psoriasis has long been known as a disease with many complications, but was attributed to diet and obesity. However, in recent years, psoriasis itself has been recognized as a series of systemic inflammatory diseases, and that the cytokines involved can induce a variety of other diseases. Individuals with psoriasis were also found to have higher incidences of cerebral and cardiovascular diseases and a younger age at death compared to healthy individuals. However, no clear guidelines have been defined regarding how much vascular lesion testing should be performed in patients with psoriasis. In this report, I attempt to unravel the objective data on psoriasis and its complications from various reviews and reports, and introduce the impact of biologics, which are currently the main treatment for psoriasis, on cardiac vascular disease.

Innate Immune Mechanisms of Arterial Hypertension and Autoimmune Disease

The immune system is indispensable in the development of vascular dysfunction and hypertension. The interplay between immune cells and the vasculature, kidneys, heart, and blood pressure regulating nuclei in the central nervous system results in a complex and closely interwoven relationship of the immune system with arterial hypertension. A better understanding of this interplay is necessary for optimized and individualized antihypertensive therapy. Our review article focuses on innate cells in hypertension and to what extent they impact on development and preservation of elevated blood pressure. Moreover, we address the association of hypertension with chronic autoimmune diseases. The latter are ideally suited to learn about immune-mediated mechanisms in cardiovascular disease leading to high blood pressure.

Chronic Systemic Inflammatory Skin Disease as a Risk Factor for Cardiovascular Disease

Chronic systemic skin disease and cardiovascular disease are multisystem disorders which have been associated with each other for centuries. Recent research has strengthened this association, particularly in systemic inflammatory disease. Here we explore the current literature on psoriasis, hidradenitis suppurativa, lupus erythematosus, acanthosis nigricans, atopic dermatitis, and bullous pemphigoid. Psoriasis is a chronic inflammatory disorder that has been labeled as a risk-modifier for hyperlipidemia and coronary artery disease by the American College of Cardiology ACC lipid guidelines. Cardiovascular disease is also found at a significantly higher rate in patients with hidradenitis suppurativa and lupus erythematosus. Some associations have even been noted between cardiovascular disease and acanthosis nigricans, atopic dermatitis, and bullous pemphigoid. While many of these associations have been attributed to a shared underlying disease process such as chronic systemic inflammation and shared underlying risk factors, these dermatologic manifestations can help to identify patients at higher risk for cardiovascular disease.

Prevalence of Metabolic Syndrome in Chinese Patients With Erythrodermic Psoriasis: A Case-Control Study

Erythroderma psoriasis (EP) is a rare and severe form of psoriasis, which is a chronic inflammatory skin disease that usually occurs simultaneously with cardiovascular disease (CVD). Metabolic syndrome (MetS) is a significant precursor of CVD. This study was to investigate the association between EP and MetS in the Chinese population. We conducted a retrospective study on 86 consecutive patients with EP and 100 healthy controls from Huashan Hospital between 2013 and 2018. Demographic, biochemical parameters for MetS, and other relevant data including the severity of EP, family history of EP, age of onset, and treatment history involved in those individuals were recorded. The prevalence of MetS in erythrodermic psoriatic patients was 88.37%, which was significantly higher than that of controls (P < 0.0001). Erythrodermic psoriatic patients also had a higher prevalence of MetS components, including abdominal obesity, dyslipidemia and hypertension, whereas hyperglycemia was similar. Adjusted for confounding factors, MetS, abdominal obesity, hypertension, smoking and alcohol use were positive independent predictors of EP (odds ratio > 1, P < 0.05). The area under the receiver operating characteristic curve calculated from determined risk factors for predicting the EP's incidence was 0.934 (95% CI 0.902-0.966). There was no correlation between the severity of EP and the prevalence of MetS. Compared with patients with mild EP, patients with moderate-to-severe EP had higher body mass index, waist circumstance and blood pressure (P < 0.05). We concluded that the prevalence of MetS and its components was higher in patients with EP. MetS an independent predictor of EP, which can favor CVD and should be encouraged to correct these cardiovascular risk factors aggressively for managing EP.

GlycA measured by NMR spectroscopy is associated with disease activity and cardiovascular disease risk in chronic inflammatory diseases

GlycA is a biomarker of systemic inflammation, quantifying both the protein concentrations and glycosylation states of several acute phase proteins. GlycA has been shown to be associated with both subclinical atherosclerosis and with cardiovascular disease (CVD). GlycA levels are higher in acute and chronic inflammation. During ongoing systemic inflammatory processes, GlycA specific acute phase reactants and proteins undergo circulating concentration and glycosylation pattern changes, and these alterations are reflected in the GlycA NMR signal. Additionally, levels associate with ongoing disease severity in individuals with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and psoriasis thus capturing active inflammation. Furthermore, in these disease states, GlycA is associated with cardiovascular disease (CVD) independent of traditional risk factors including C-reactive protein (CRP). Finally, GlycA levels decrease with exercise, weight loss, and systemic anti-inflammatory agents. Therefore, GlycA appears to be a promising new composite biomarker of active systemic inflammation including assessing CVD risk in patients with inflammatory diseases.

•

Patients with chronic inflammatory disorders are at increased risk for cardiovascular diseasenot captured by traditional risk factors.

•

GlycA is a biomarker of acute phase reactants by NMR spectroscopy which captures disease activity in human inflammatory diseases.

•

GlycA associates with cardiovascular disease and offers a tool to monitor primary disease activity and assess CVD risk in inflammatory diseases.

The Risk of Systemic Diseases in Those with Psoriasis and Psoriatic Arthritis: From Mechanisms to Clinic

Psoriasis and psoriatic arthritis (PsA) have been recently considered as chronic systemic inflammatory disorders. Over the past decades, enormous evidence indicates that patients with psoriasis and PsA have a higher risk of developing various comorbidities including cardiovascular disease, metabolic disease, cancers, infections, autoimmune disease, and psychiatric diseases. However, reported risks of some comorbidities in those with psoriasis and PsA are somewhat different according to the research design. Moreover, pathomechanisms underlying comorbidities of those with psoriasis and PsA remain poorly elucidated. The purpose of this review is to provide the most updated comprehensive view of the risk of systemic comorbidities in those with psoriasis and PsA. Molecular mechanisms associated with the development of various comorbidities in those with psoriasis and PsA are also reviewed based on recent laboratory and clinical investigations. Identifying the risk of systemic comorbidities and its associated pathomechanisms in those with psoriasis and PsA could provide a sufficient basis to use a multi-disciplinary approach for treating patients with psoriasis and PsA.

Psoriasis and Its Impact on In-Hospital Outcome in Patients Hospitalized with Acute Kidney Injury

BACKGROUND

Psoriasis is a chronic inflammatory disease which affects the body far beyond the skin. Whereas there is solid evidence that chronic skin inflammation in psoriasis drives cardiovascular disease, the impact on renal impairment and acute kidney injury (AKI) is still unclear. We aimed to analyze the impact of psoriasis on the in-hospital outcome of patients hospitalized with AKI.

METHODS

In this retrospective database study, we investigated data on characteristics, comorbidities, and in-hospital outcomes for all hospitalized patients with AKI stratified for concomitant psoriasis, which were collected by the Federal Office of Statistics in Germany between 2005 and 2016.

RESULTS

Among the 3,162,449 patients treated for AKI in German hospitals between 2005 and 2016, 11,985 patients (0.4%) additionally suffered from psoriasis. While the annual number of AKI patients with psoriasis increased significantly from 485 cases (4.0%) in 2005 to 1902 (15.9%) in 2016 (p < 0.001), the in-hospital mortality decreased substantially (from 24.9% in 2005 to 17.4% in 2016; p < 0.001). AKI patients with concomitant psoriasis were younger (70 (IQR; 60-78) vs. 76 (67-83) years; p < 0.001) and were more often treated with dialysis (16.3% vs. 13.6%, p < 0.001). Presence of psoriasis in AKI patients was associated with reduced prevalence of myocardial infarction (OR 0.62; p < 0.001), stroke (OR 0.85; p = 0.013), and in-hospital mortality (OR 0.75; p < 0.001).

CONCLUSIONS

AKI patients with psoriasis were hospitalized in median 6 years earlier than those without. Despite younger age, we detected higher use of kidney replacement therapy in patients with psoriasis, indicating a more severe course of AKI. Our findings might improve management of these patients and contribute evidence for extracutaneous, systemic manifestations of psoriasis.
