Psoriasis is associated with lipid abnormalities at the onset of skin disease

Biomarkers of subclinical atherosclerosis in patients with psoriatic arthritis

Background: Psoriatic arthritis (PsA) is a chronic immune-mediated disease. It is associated with an increase in cardiovascular risk factors (obesity, hypertension, diabetes, and dyslipidemia), giving a higher risk of major adverse cardiovascular events. Patients with PsA have an increased incidence of subclinical atherosclerosis and endothelial dysfunction. The aim of this study is to perform a review of the biomarkers of subclinical atherosclerosis in patients with PsA.

Methods: A search was performed in the electronic databases (PubMed, Web of Science, Scopus, and Embase) up until July 2017. Studies were considered if they included data on biomarkers of subclinical atherosclerosis in PsA, and each article was then reviewed for quality and clinical relevance. After completing the literature search, all screened literature was summarized and discussed in our study group (CaRRDs study group).

Results: The initial search produced 532 abstracts, which were limited to 258 potentially relevant articles by preliminary review of the titles and by excluding review articles and case reports (n=274). A further 102 articles were deemed ineligible after examining the abstracts. Full texts of the remaining 156 articles were retrieved. Most articles were excluded because they were not relevant to the biomarkers of subclinical atherosclerosis in psoriasis and/or PsA. In the end, 54 articles were deemed eligible for this review.

Conclusion: Patients with PsA showed more severe atherosclerotic disease compared with patients with only psoriasis. This may have been due to the higher systemic inflammatory burden from the combination of both diseases. In patients with PsA some molecules may be considered as markers of atherosclerotic disease, and their detection may be a prognostic marker, in addition to imaging procedures, for the development of atherosclerotic disease, and could be suitable for the management of patients with PsA.

Methylenetetrahydrofolate Reductase C677T Gene Polymorphism as Risk Factor for Psoriasis in Saudis

Methylenetetrahydrofolate reductase (MTHFR) has been linked with the etiopathogenesis of psoriasis with inconsistent results. Methylenetetrahydrofolate reductase C677T polymorphism was evaluated in 106 Saudi psoriasis vulgaris patients and 280 matched healthy controls using PCR-RFLP (restriction fragment length plymorphism) technique. The cardiovascular risk factors were also compared in cases and controls. Allele T and genotypes CT and TT were found to be increased while allele C and genotype CC significantly decreased in psoriasis patients as compared with controls (P < .001). These results showed that the T-allele and T-containing genotypes (TT, CT) of MTHFR C677T are significantly linked with psoriasis susceptibility while C-allele and CC genotype are protective for it. Body mass index, fasting glucose, total cholesterol, low-density lipoprotein, triglycerides, and C-reactive protein, known markers for cardiovascular diseases, were found to be significantly elevated in the patient group as compared with the controls. It is concluded that the MTHFR C677T polymorphism increases psoriasis risk in Saudi patients.

High burden of the metabolic syndrome and its component disorders in South Africans with psoriasis

BACKGROUND

Psoriasis is associated with cardiometabolic diseases (CMDs) in Caucasians, but no data is available from sub-Saharan populations on either CMD prevalence or psoriasis risk factors. Our aim was to investigate the prevalence of CMDs in a predominantly non-Caucasian cohort of South Africans with psoriasis and to determine the principal risk factors associated with psoriasis.

METHODS

This was a cross-sectional case-control study of adult psoriasis patients (n = 103) and controls (n = 98), comparing sociodemographic, anthropometric, clinical, and biochemical characteristics. The groups were matched for gender, ethnicity, and body mass index (BMI).

RESULTS

The prevalence of metabolic syndrome (MetS) (52.4% vs. 33.7%; P = 0.007), type 2 diabetes (T2D) (25.2% vs. 4.1%; P < 0.0001), and hypertension (70.9% vs. 46.6%; P = 0.001) were all higher in the psoriasis group. High-sensitivity CRP was higher in psoriasis patients than controls (4.70 (2.00, 10.9) vs. 2.00 (1.10, 4.80) ng/ml; P < 0.0005). Multivariable logistic regression analysis showed that severe psoriasis was independently associated with MetS (odds ratio [95% CIs]: 4.42 [1.72, 11.4]; P = 0.002), T2D (11.3 [3.07, 41.3]; P = 0.0002), and hypertension (2.48 [0.97, 6.32]; P = 0.05), whilst for psoriasis the principal risk factors were smoking (3.87 [1.97, 7.63]; P < 0.0001) and hsCRP (1.05 [1.00, 1.10]; P = 0.029), with completion of high school (0.23 [0.11, 0.48]; P < 0.0001) being protective.

CONCLUSIONS

In this population, psoriasis is characterized by a high burden of CMDs, particularly in those subjects with severe psoriasis. Inflammation plays a role in the etiology of psoriasis, whilst smoking and poor education further increase disease risk.

Association between physical activity and risk of prevalent psoriasis: A MOOSE-compliant meta-analysis

Psoriasis is a common chronic relapsing immune-mediated inflammatory disease, whose prevalence has increased in recent years. Some physicians believe that physical activity is associated with numerous health-related benefits in adults with dermatoses. While numerous studies have suggested an association between psoriasis and physical activity, others have yielded contradictory results. The aim of our study was to evaluate the association between the level of physical activity and prevalence of psoriasis.A comprehensive search of the literature was performed from January 1970 to February 2017 using EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials electronic databases. Studies published in English were reviewed to identify the contribution of intensity of physical activity on the prevalence of psoriasis.The search strategy yielded 1100 relevant studies, among which 13 observational studies were included. We found that patients with psoriasis exercise significantly less vigorously than controls (relative risk [RR]: 0.76; 95% confidence interval [CI]: 0.67-0.85; P < .00001). Predominantly, these patients exercised at moderate intensity (RR: 0.40; 95% CI: 0.18-0.90; P = .03). Some patients had lesser degree of movement, and some exercised strenuously. There were no significant differences observed in the intensity of exercise performed by controls (RR: 0.90; 95% CI: 0.46-1.77; P = .76). The 3 studies found the frequency of regular exercise differed significantly between patients with psoriasis and controls (RR: 0.88; 95% CI: 0.82-0.95; P = .0007).Different severities of psoriasis have different influences on patients' physical activity levels. Patients with a higher proportion of psoriatic lesions and self-awareness were associated with lower-intensity exercises. Our meta-analysis highlights the fact that intense physical activity may lower the prevalence of psoriasis.

Psoriasis as a cardiovascular risk factor: updates and algorithmic approach

Although psoriasis is predominantly a chronic inflammatory skin disorder, it has been known to be associated with cardiovascular disease. Patients with psoriasis, particularly with moderate to severe forms, present an increased rate of cardiovascular mortality, myocardial infarction and stroke. However the pathophysiology of the relationship between psoriasis and cardiovascular risk and comorbidities has not yet completely known. Chronic inflammation may be considered a solid link between psoriasis and related cardiovascular events. Several cytokines and inflammatory cells play a pivotal role in the development of psoriatic lesions, resulting in angiogenesis and endothelial dysfunction. Furthermore, the imbalance between oxidative stress and antioxidant mechanisms in psoriatic patients may contribute to explain the pathogenesis of increased reactive oxygen species and the formation of atherosclerotic plaque. Other mechanistic pathways which may be involved in this relationship include cardiovascular effects of medications, a common genetic background and a higher prevalence of cardiovascular risk factors, which are often under-diagnosed and under-treated in psoriatic patients. Indeed, the early detection of specific markers of cardiovascular impairment, such as N-terminal pro B-type natriuretic peptide, homocysteine and YKL-40, may enable psoriatic patients at higher cardiovascular risk to be identified as soon as possible. This review examines the increased cardiovascular risk profile and high prevalence of cardiovascular disease associated with psoriasis, focusing on pathogenic links between psoriasis and atherosclerosis, serological markers of cardiovascular involvement and the implications of antipsoriatic therapies on cardiovascular risk and proposes a flow chart, that every dermatologist should follow to screen psoriatic patients.

Prevalence of smoking, alcohol consumption and metabolic syndrome in patients with psoriasis

BACKGROUND

Coexistence of obesity, hypertension, insulin resistance and dyslipidemia is defined as metabolic syndrome (MBS), which is among the important risk indicators for cardiovascular diseases, diabetes and stroke. Smoking and alcohol consumption are the other factors which lead to an increase in the risk of cardiovascular disease.

OBJECTIVE

To investigate the prevalence of metabolic syndrome, smoking and alcohol consumption in psoriasis patients and the relationship between disease severity and these factors.

METHODS

This cross-sectional study enrolled 563 patients with chronic plaque-type psoriasis, all of which completed a questionnaire and underwent a complete physical examination. Data about MBS components, psoriasis severity/duration, smoking and alcohol consumption, and cardiovascular diseases were recorded.

RESULTS

A total of 563 patients with ages ranging from 18 to 78 years were evaluated. Metabolic syndrome was found in 12.6% of the patients [central obesity (38.7%), hypertension (14.3%), dyslipidemia (18.6%), diabetes (9.2%)], while 50.3% had smoking, and 3.3% had alcohol consumption. Patients with metabolic syndrome were older and more likely to have a longer disease duration than those without metabolic syndrome (p<0.05 for each). The prevalence of metabolic syndrome was higher in women than in men. Psoriasis was more severe in patients with central obesity, diabetes and smoking than in those without (p<0.05 for each).

STUDY LIMITATIONS

Retrospective design.

CONCLUSIONS

Our results indicate that MBS is a risk factor for psoriasis patients with advanced age. The relationship between disease severity and obesity, diabetes, and smoking in psoriasis patients indicates that the patients should be informed about the potential metabolic risks and receive therapies for behavioral changes besides anti-psoriatic treatment in order to minimize these risks.

Effectiveness of Lipid-Lowering Statin Therapy in Patients With and Without Psoriasis

BACKGROUND

Psoriasis is associated with dyslipidemia and metabolic syndrome, and has been linked to an increased cardiovascular risk. The aim of this study was to compare baseline characteristics and effects of statin therapy on lipid levels and cardiovascular outcomes in patients with and without psoriasis.

METHODS

This post-hoc analysis assessed patients from one primary cardiovascular prevention statin trial (Collaborative AtoRvastatin Diabetes Study [CARDS]) and two secondary cardiovascular prevention statin trials (Treating to New Targets [TNT] and Incremental Decrease in End Points Through Aggressive Lipid Lowering [IDEAL]). Baseline characteristics, lipid changes from baseline, and cardiovascular event rates were analyzed. TNT and IDEAL data were pooled.

RESULTS

Baseline characteristics and lipid profiles differed minimally in patients with and without psoriasis. In CARDS and TNT/IDEAL, similar apolipoprotein B, total cholesterol, and low-density lipoprotein cholesterol reductions occurred with statin therapy in patients with or without psoriasis. High-dose atorvastatin significantly reduced cardiovascular events vs. standard/low-dose statins in patients without psoriasis in TNT/IDEAL; similar numeric differences in event rates were observed in patients with psoriasis.

CONCLUSIONS

In this post-hoc analysis, statins improved lipid levels and cardiovascular outcomes in patients with and without psoriasis, supporting statin use in patients with psoriasis. Trial registration (ClinicalTrials.gov) NCT00327418, registered 16 May, 2006; NCT00327691, registered 16 May, 2006; NCT00159835, registered 8 September, 2005.

Excessive angiogenesis associated with psoriasis as a cause for cardiovascular ischaemia

Psoriasis, a common disease affecting 2%-3% of the UK population, produces significant impairment of quality of life and is an immense burden on sufferers and their families. Psoriasis is associated with significant cardiovascular comorbidity and the metabolic syndrome. Angiogenesis, a relatively under-researched component of psoriasis, is a key factor in pathogenesis of psoriasis and also contributes to the development of atherosclerosis. Vascular endothelial growth factor (VEGF) is a well-established mediator of pathological angiogenesis which is upregulated in psoriasis. It is possible that, in patients with psoriasis, cutaneous angiogenesis may be both a marker for systemic vascular pathology and a novel therapeutic target. In this viewpoint study, the role of VEGF-mediated angiogenesis as a cause for cardiovascular events in patients with psoriasis is explored.

Double trouble: psoriasis and cardiometabolic disorders

Psoriasis (PsO) is a chronic immune-mediated inflammatory skin disorder associated with numerous co-morbidities. This descriptive review focuses on the cardiometabolic co-morbidities of PsO with reference to the epidemiology and pathogenetic mechanisms linking PsO and cardiometabolic disease (CMD). Registry-based studies have shown PsO to be associated with an increased risk of cardiovascular morbidity and mortality. Factors linking PsO and CMD include: chronic inflammation, obesity, classic cardiovascular risk factors, and the effects of systemic therapy used to treat PsO. Chronic inflammation is associated with PsO itself, and with obesity. Adipose tissue is responsible for the secretion of various adipokines, which together with pro-inflammatory cytokines arising from the psoriatic plaque, contribute to the proinflammatory and pro-atherogenic environment. Systemic therapy aimed at decreasing inflammation has been shown to improve CMD in PsO. Screening for and treating CMD and initiating lifestyle modifications will remain the most important interventions until further data emerge regarding the effect of systemic therapy on CMD progression.

Concentration of selenium, zinc, copper, Cu/Zn ratio, total antioxidant status and c-reactive protein in the serum of patients with psoriasis treated by narrow-band ultraviolet B phototherapy: A case-control study

BACKGROUND

Psoriasis is a common, an inflammatory skin disease. Trace elements may play an active role in the pathogenesis of psoriasis.

OBJECTIVE

The aim of this study was to estimate the concentration of selenium (Se), zinc (Zn), copper (Cu) and Cu/Zn ratio as well as total antioxidant status (TAS) and c-reactive protein (CRP) in the serum of patients with psoriasis.

METHODS

In this case-control study sixty patients with psoriasis and fifty-eight healthy people were examined. Serum levels of Se, Zn and Cu were determined by atomic absorption spectrometry. Cu/Zn ratio was calculated. TAS was measured spectrophotometrically. CRP was analyzed by immunoturbidimetric method. Clinical activity of psoriasis was evaluated using Psoriasis Area and Severity Index (PASI).

RESULTS

Serum concentration of Se in patients with psoriasis (71.89±16.90μg/L) was lower as compared to the control group (79.42±18.97μg/L) and after NB-UVB. Cu level of patients was higher (1.151±0.320mg/L) as compared to controls (1.038±0.336mg/L), but Zn level did not differ. We observed higher Cu/Zn ratio (p<0.05) in examined patients than in the control group and after NB-UVB. We found decrease TAS before and after NB-UVB. CRP levels was found to be normal range. A significant correlation coefficient between CRP and Cu/Zn was observed.

CONCLUSIONS

The study showed some disturbances in the serum levels of trace elements and TAS in psoriatic patients.

Associations between body mass index and severity of psoriasis

Objective

Compared with healthy people, overweight and obesity are more commonly found among those suffering from skin conditions such as psoriasis. The present study was an attempt to survey the relationship between obesity and intensity of psoriasis.

Patients and methods

A total of 42 patients with psoriasis who were referred to Farshchian Hospital, Hamadan, participated in this cross-sectional descriptive–analytical study. Patients were classified into mild, moderate and severe based on the intensity of the disease measured by Psoriasis Area and Severity Index (PASI). Body mass index (BMI), waist size, age, gender, smoking and drinking habits of the participants were measured and compared.

Results

A total of 15 (35.07%) patients had mild psoriasis, 9 (21.4%) patients had moderate psoriasis and 18 (42.9%) patients suffered from severe psoriasis. Mean BMI of mild psoriasis patients was 25.86±5.93 kg/m², and this figure for the moderate and severe psoriasis patients was 30.85±3.77 kg/m² and 26.96±5.68 kg/m², respectively (P=0.096). Mean waist size of the mild psoriasis patients was 91.54±11.49 cm, and for moderate and severe patients, it was 99±8.39 cm and 92.17±10.73 cm, respectively (P=0.211).

Conclusion

The results of this study showed no significant difference between mean value of body mass index, waist size, age and gender in mild, moderate and severe groups of the psoriasis patients.

Untargeted serum metabonomics study of psoriasis vulgaris based on ultra-performance liquid chromatography coupled to mass spectrometry

Psoriasis is a common, chronic, systemic inflammatory skin disease, the etiology and pathogenesis is unclear. An untargeted high-throughput metabonomics method based on liquid chromatography coupled to mass spectrometry was applied to study the serum metabolic changes in psoriasis vulgaris patients, and to discover serum potential biomarkers for identification, diagnosis and exploring pathogenesis of psoriasis. The serum metabolic profiles from 150 subjects (75 psoriasis patients and 75 healthy controls) were acquired, the raw spectrometric data were processed by multivariate statistical analysis, and 44 potential biomarkers were screened out and identified. The potential biomarkers were mainly involved in glycerophospholipid metabolism, sphingolipid metabolism, arachidonic acid metabolism, bile acid biosynthesis, indicated the pathogenesis of psoriasis may be related to the disturbed metabolic pathways.

Systemic Inflammation, Oxidative Damage to Nucleic Acids, and Metabolic Syndrome in the Pathogenesis of Psoriasis

In the pathogenesis of psoriasis, systemic inflammation and oxidative stress play mutual roles interrelated with metabolic syndrome (MetS). This study aims to map the selected markers of inflammation (C-reactive protein (CRP)), oxidative damage to nucleic acids (DNA/RNA damage; 8-hydroxy-2'-deoxyguanosine, 8-hydroxyguanosine, and 8-hydroxyguanine), and the parameters of MetS (waist circumference, fasting glucose, triglycerides, high-density lipoprotein (HDL) cholesterol, diastolic and systolic blood pressure) in a group of 37 patients with psoriasis (62% of MetS) and in 43 healthy controls (42% of MetS). Levels of CRP, DNA/RNA damage, fasting glucose, and triglycerides were significantly elevated in patients. MetS in conjunction with psoriasis was associated with high levels of CRP, significantly higher than in control subjects without MetS. Patients with MetS exhibited further DNA/RNA damage, which was significantly higher in comparison with the control group. Our study supports the independent role of psoriasis and MetS in the increase of CRP and DNA/RNA damage. The psoriasis contributes to an increase in the levels of both effects more significantly than MetS. The psoriasis also diminished the relationship between CRP and oxidative damage to nucleic acids existent in controls.

Combined Transcriptomic Analysis Revealed AKR1B10 Played an Important Role in Psoriasis through the Dysregulated Lipid Pathway and Overproliferation of Keratinocyte

RNA-seq has enabled in-depth analysis of the pathogenesis of psoriasis on the transcriptomic level, and many biomarkers have been discovered to be related to the immune response, lipid metabolism, and keratinocyte proliferation. However, few studies have combined analysis from various datasets. In this study, we integrated different psoriasis RNA-seq datasets to reveal the pathogenesis of psoriasis through the analysis of differentially expressed genes (DEGs), pathway analysis, and functional annotation. The revealed biomarkers were further validated through proliferation phenotypes. The results showed that DEGs were functionally related to lipid metabolism and keratinocyte differentiation dysregulation. The results also showed new biomarkers, such as AKR1B10 and PLA2G gene families, as well as pathways that include the PPAR signaling pathway, cytokine-cytokine receptor interaction, alpha-linoleic acid metabolism, and glycosphingolipid biosynthesis. Using siRNA knockdown assays, we further validated the role that the AKR1B10 gene plays in proliferation. Our study demonstrated not only the dysfunction of the AKR1B10 gene in lipid metabolizing but also its important role in the overproliferation and migration of keratinocyte, which provided evidence for further therapeutic uses for psoriasis.

Prevalence of metabolic syndrome in patients with psoriasis: a hospital-based cross-sectional study

BACKGROUND:

Emerging epidemiological evidence suggests independent associations between psoriasis and metabolic syndrome. Objectives: The aim of the study was to examine the prevalence of metabolic syndrome and its components in patients with psoriasis, and to assess which factors may predict metabolic syndrome in these patients.

METHODS:

A hospital-based, cross-sectional study with 244 psoriatic patients and 163 control subjects with skin diseases other than psoriasis was conducted at the Clinic of Dermatovenerology, Clinical Center of Serbia, Belgrade, from October 2011 to October 2012. Metabolic syndrome was defined using the revised National Cholesterol Education Program Adult Treatment Panel III. Severity of psoriasis was measured by Psoriasis Area and Severity Index and Body Surface Area.

RESULTS:

The adjusted odds ratios (ORs) and 95% confidence intervals (CI) for psoriasis patients vs. non-psoriasis patients were 2.66 (95% CI, 1.58-4.42) for metabolic syndrome, 3.81 (95% CI, 2.30-6.31) for hypertension, 2.29 (95% CI, 1.39-3.78) for central obesity, 1.92 (95% CI, 1.08-3.41) for hyperglycemia, 1.87 (95% CI 1.18-2.96) for low high-density lipoprotein cholesterol level, and 1.42 (95% CI, 0.87-1.04) for hypertrigliceridemia. We failed to find any statistically significant association between the metabolic syndrome and clinical severity of psoriasis. Later onset and longer duration of psoriasis were predicting factors for metabolic syndrome in our patients. Study limitations: The cross-sectional design of the study does not allow us to draw directional causal inferences concerning the association between psoriasis and metabolic syndrome. Factors such as diet, alcohol consumption or mental health, which have not been evaluated in this study, may be confounders in this relation.

CONCLUSION:

A higher prevalence of metabolic syndrome and its components in patients with psoriasis than in controls, regardless of disease severity, emphasizes the need for early treatment and follow-up of all psoriatic patients with respect to metabolic diseases.

Psoriasis-associated vascular disease: the role of HDL

Psoriasis is a chronic inflammatory systemic disease with a prevalence of 2-3%. Overwhelming evidence show an epidemiological association between psoriasis, cardiovascular disease and atherosclerosis. Cardiovascular disease is the most frequent cause of death in patients with severe psoriasis. Several cardiovascular disease classical risk factors are also increased in psoriasis but the psoriasis-associated risk persists after adjusting for other risk factors.Investigation has focused on finding explanations for these epidemiological data. Several studies have demonstrated significant lipid metabolism and HDL composition and function alterations in psoriatic patients. Altered HDL function is clearly one of the mechanisms involved, as these particles are of the utmost importance in atherosclerosis defense. Recent data indicate that biologic therapy can reverse both structural and functional HDL alterations in psoriasis, reinforcing their therapeutic potential.

Increased Risk of Atrial Fibrillation and Thromboembolism in Patients with Severe Psoriasis: a Nationwide Population-based Study

Psoriasis increases the risk of atrial fibrillation (AF) and thromboembolic events (TE). There is limited information on the effect of psoriasis severity on AF and TE. In this study, psoriasis patients were enrolled from the Korean National Insurance Service-National Sample Cohort (2004–2008). Diagnosis and disease severity were determined from claims data. Newly diagnosed non-valvular AF and TE were identified during a 9.6-year follow-up. The effect of psoriasis severity on AF and TE was evaluated. We identified 13,385 psoriasis patients (1,947 with severe psoriasis). Severe psoriasis significantly increased the risk of AF (adjusted hazard ratio [HR_adjust] 1.44 [95% confidence interval (CI) 1.14–1.82], p = 0.002) and TE (HR_adjust 1.26 [95% CI 1.07–1.47], p = 0.005); mild psoriasis did not show any significant effects. Results were similar after propensity-score matching. Risk increments of AF and TE were prominent in patients with greater cardiovascular risk. A possible limitation of our study is that it has a retrospective design, and the effect of unmeasured confounders and risk of misclassification could bias the results. To conclude, our results showed that severe, but not mild, psoriasis significantly increased AF and TE risk. AF surveillance and active stroke prevention would be beneficial in such cases.

Psoriasis and Cardiovascular Risk-Do Promising New Biomarkers Have Clinical Impact?

Epidemiological studies suggest an increased prevalence of cardiovascular disease (CVD) in patients with psoriasis (PS). Therefore, emphasis has lately been laid on the necessity for clinical evaluation of the risk of CVD in these patients. The systemic inflammatory markers C-reactive protein (CRP) and interleukin- (IL-) 6, which have long been used to predict future CVD in the general population, are increased manyfold in patients with PS. Lipid abnormalities characterized by elevated triglycerides, low HDL cholesterol, and higher concentrations of LDL cholesterol and its oxidized form are also prevalent in patients. There is a need for additional laboratory markers for the assessment of cardiovascular status of patients with PS. Due to frequent comorbid overweight and obesity, biologically active compounds produced by adipocytes may have an impact on monitoring the status of the cardiovascular system of patients with PS. For this purpose, two adipokines, adiponectin and leptin, have been most extensively studied. The review focuses on some inflammatory and oxidative stress aspects in patients with PS through the analysis of the impact of prominent adipokines and oxidized low-density lipoprotein (oxLDL) to assess their eligibility for clinical practice as markers of CVD risk in patients with PS.

Association of Metabolic Syndrome in Chronic Plaque Psoriasis Patients and their Correlation with Disease Severity, Duration and Age: A Case Control Study from Western Maharashtra

INTRODUCTION

Psoriasis is a chronic systemic inflammatory disease where the skin and the joints are the primary targets. Despite the fact that psoriasis carries minimal risk of mortality, it is associated with significant morbidity which may have a significant impact on quality of life of patients. Globally, psoriasis has been reported to be associated with Metabolic Syndrome (MS) including obesity, dyslipidemia, diabetes and hypertension. Association of MS and its various components with psoriasis has been consistently reported in various studies, but there is a paucity of data on this association from the Indian subcontinent.

AIM

To compare the prevalence of MS in patients with psoriasis and controls and to determine association of MS with age of patient, severity and duration of psoriasis.

MATERIALS AND METHODS

A hospital based case control study on 95 psoriasis patients and 95 age and sex matched controls. MS was diagnosed by the presence of three or more of the South Asian Modified National Cholesterol Education Program's Adult Panel III SAM-NCEP criteria. Clinical, biometric and necessary laboratory evaluations were performed. Statistical analysis was performed by using Statistical Package for the Social Sciences (SPSS version 16.0). Data was compared between cases and controls using unpaired t-test and chi-square test and odds ratio with 95% confidence interval.

RESULTS

MS was significantly more common in psoriatic patients than in controls (38.9%vs 21.05%, odds ratio 2.39, 95% confidence interval, 1.26-4.55; p-value=0.007). Psoriatic patients had higher prevalence of hypertriglyceridemia (45.2%vs.11.5%), decreased HDL cholesterol (27.3%vs.4.2%), abdominal obesity (32.6% vs.15.7%) and elevated blood pressure (18.9%vs.5.2%) whereas no association observed for elevated blood sugar level (12.6%vs.5.2%). MS was present in psoriasis cohort irrespective of severity and duration of psoriasis. (p-value 0.123, 0.596 respectively). MS was more prevalent in elderly individuals with psoriasis (51.1%vs.28% p-value=0.008; Odds ratio 3.12, 95% confidence interval 1.32-7.35).

CONCLUSION

Significant association between psoriasis and MS was noted and it was independent of disease duration and severity. Elderly psoriatic patients were more prone for developing MS. We suggest that all patients of psoriasis, irrespective of disease, duration and severity, should be screened for MS to prevent significant morbidity and mortality associated with it.

Psoriasis and comorbid diseases: Epidemiology

Psoriasis is a common chronic inflammatory disease of the skin that is increasingly being recognized as a systemic inflammatory disorder. Psoriatic arthritis is a well-known comorbidity of psoriasis. A rapidly expanding body of literature in various populations and settings supports additional associations between psoriasis and cardiometabolic diseases, gastrointestinal diseases, kidney disease, malignancy, infection, and mood disorders. The pathogenesis of comorbid disease in patients with psoriasis remains unknown; however, shared inflammatory pathways, cellular mediators, genetic susceptibility, and common risk factors are hypothesized to be contributing elements. As additional psoriasis comorbidities continue to emerge, education of health care providers is essential to ensuring comprehensive medical care for patients with psoriasis.

Tofacitinib for the treatment of psoriasis

INTRODUCTION

The identification of a number of psoriasis-susceptibility genes and a better understanding of the pathogenesis of the intracellular metabolic pathways, have generated new perspectives on psoriasis treatment, in particular new compounds that inhibit certain intracellular proteins involved in the immune response. In contrast to biologic agents, these compounds block intracellular targets such as transcriptional factors or enzymes.

AREAS COVERED

Tofacitinib is a small molecule that acts as a reversible, competitive inhibitor of ATP in the ATP binding site of JAK proteins, determining their inactivation, thus prevents the downstream activation of the STAT proteins, which are then unable to up-regulate the pro-inflammatory genes implicated in psoriasis. The authors present an overview of Phases I - III clinical trials of tofacitinib for psoriasis based on peer-reviewed literature.

EXPERT OPINION

In clinical practice, it is important to assess the response of psoriasis to tofacitinib and identify possible clinical, genetic, and immune biomarkers to predict the response. Comorbidities associated with psoriasis, in particular metabolic syndrome and obesity, are also an important aspect of using tofacitinib in clinical practice. There are some evidences that a drug such as tofacitinib could be used to improve not only psoriasis, but also some of its important comorbidities.

Diagnosis and underdiagnosis of comorbidities in psoriasis patients - need for a multidisciplinary approach

BACKGROUND:

Psoriasis is an immune-mediated disease that manifests predominantly in the skin, although systemic involvement may also occur. Although associated comorbidities have long been recognized and despite several studies indicating psoriasis as an independent risk factor for cardiovascular events, little has been done in general medical practice regardind screening. In the United States, less than 50% of clinicians are aware of these recommendations.

OBJECTIVE:

To identify the prevalence of these comorbidities in 296 patients followed up at a university dermatology clinic.

METHODS:

Systematically investigated comorbidity frequencies were compared with general practitioners' registry frequencies. Clinical features correlated with comorbidities were also investigated.

RESULTS:

High prevalences of systematically investigated comorbidities such as hypertension (30%) and dyslipidemia (26.5%) were documented. Conversely, data from general practitioners' records showed that 33% of dyslipidemia cases were undiagnosed and indicated possible underdiagnosis of some comorbidities. Furthermore, an association was found between: the number of comorbidities and psoriasis duration, age and high body mass index an association was found between the number of comorbidities and psoriasis duration, age, high body mass index, waist circumference or waist-to-hip ratio. (p<0.05).

CONCLUSION:

Disease duration, age and high body mass index, waist circumference or waist-to-hip ratio are possible criteria for choosing which patients should be screened for comorbidities. Underdiagnosis of comorbidities by general practitioners highlights the need for a multidisciplinary approach in psoriasis management.

Lipoprotein Metabolism and Inflammation in Patients With Psoriasis

Psoriasis is a chronic inflammatory disease associated with a variety of co-morbid conditions, including cardiovascular disease. Advancements in our understanding of the cellular and molecular mechanisms of psoriasis have led to a better understanding regarding its pathogenesis, which in turn has stimulated ongoing research to identify the underlying pathophysiology responsible for the increased risk of cardiovascular events associated with psoriasis. Although not yet fully elucidated, emerging evidence points to immune-mediated inflammation as a process that contributes to endothelial cell dysfunction, dyslipidemia, and atherosclerosis as key processes influencing cardiovascular disease in psoriasis. In particular, the dyslipidemia present in psoriasis may be associated with altered lipoprotein function and increased atherogenicity. Here, we review how the cytokine networks involved in lipoprotein metabolism and inflammation could impact on the cardiovascular disease risk for patients with psoriasis.

The Association between Symptoms of Dry Eye Syndrome and Metabolic Outcome in a General Population in Korea

Dry eye syndrome (DES) is recognized as a public health concern. One of the pathophysiologies in the development of DES is inflammation, and metabolic syndrome (MetS), which is highly prevalent in the general population, is a well-known chronic and systemic inflammatory condition. Despite the increasing interest regarding a relationship between DES and MetS, information is lacking on the association between DES and MetS and its individual components. We investigated the association between DES symptoms and MetS and its components among adults aged ≥ 19 years using population-based data from the Korea National Health and Nutrition Examination Survey V. A sample group of 15,294 adults (42.67% men and 57.33% women) completed household interviews in which they provided blood (for high-density lipoprotein cholesterol, triglyceride, and glucose) and anthropometric measurements (including waist circumference, weight, and height) to define MetS. We also collected information regarding sociodemographic and behavioral risk factors. The survey results showed that 11.50% of men and 22.35% of women experienced DES and 5.30% of patients had both DES and diagnosis of MetS, including 204 men and 606 women. Thus, no significant difference was observed between DES and the diagnosis of MetS according to sex (P = 0.4008 in men; P = 0.0804 in women); however, a significant association was observed between DES and hypertriglyceridemia in women (OR, 1.13; 95% CI, 1.01-1.29). Therefore, hypertriglyceridemia might be an important factor in the association between DES and MetS. Further longitudinal research is needed to evaluate this relationship.

Age and gender differences in Framingham risk score and metabolic syndrome in psoriasis patients: A cross-sectional study in the Turkish population

Objective:

Psoriasis is associated with an increased frequency of cardiovascular risk factors. Metabolic syndrome (MS) and the Framingham risk score (FRS) are two different algorithms for evaluating cardiovascular risk. They include different features: waist circumference measurement is included in the MS criteria, whereas smoking, age, and gender are questioned in FRS. This study aimed to evaluate the frequency of MS and FRS in psoriasis patients compared with a control group and investigate the differences between MS and FRS.

Methods:

This was a cross-sectional study involving 300 psoriasis patients and 177 controls. MS, FRS, and disease severity were evaluated.

Results:

The frequency of MS was higher in females with psoriasis than in those in the control group (p=0.019). Females in the psoriasis group were more obese than those in the control group (p=0.036). FRS significantly differed between the patients and controls of age >60 years (p=0.006). The risk of hypertension in current and past smokers was higher in the psoriasis patients (OR=2.07 and 2.32–2.48, respectively) than in the control group. There was no statistically significant relationship among MS, FRS, and psoriasis severity (p>0.05).

Conclusion:

The results of this study support the evaluation of cardiovascular risk assessment in female psoriasis patients with MS and in male and elderly psoriasis patients with FRS.

Active peripheral inflammation is associated with pro-atherogenic lipid profile in psoriatic arthritis

OBJECTIVE

The association between psoriatic arthritis (PsA) disease activity and lipid profiles has not been explored. We studied the association between active peripheral arthritis and/or enthesitis/daclylitis with lipid measurements in PsA.

METHODS

We conducted a cross-sectional study of PsA patients enrolled in the Consortium of Rheumatology Researchers of North American (CORRONA) registry. Low activity was defined as Clinical Disease Activity Index (CDAI) ≤ 10 without enthesitis or dactylitis. Moderate-to-high peripheral disease activity was defined as CDAI > 10 and/or the presence of enthesitis/dactylitis.

RESULTS

Of the 4672 patients with PsA enrolled in the CORRONA registry from June 2008 to October 2012, 725 (15.5%) had complete data on CDAI and lipid measurements. Of them, 284 (39%) patients had CDAI > 10 and/or enthesitis/dactylitis. Moderate-to-high group included more women and more current smokers. Patients with moderate-to-high disease activity had shorter duration of disease, and were more likely to be on prednisone, but less likely to use tumor necrosis factor (TNF) inhibitors. Moderate-to-high peripheral disease activity was associated with abnormal total cholesterol (TC) (>200mg/dl), odds ratio (OR) = 1.58; 95% CI: (1.11, 2.24); p = 0.01, and abnormal triglycerides (TG) (>150mg/dl), OR = 1.64; 95% CI: (1.16, 2.32); p = 0.005, after adjusting for gender, duration of PsA, smoking, body mass index, diabetes, modified Heath Assessment Questionnaire scores, as well as the following medications: methotrexate, other non-biologic disease modifying anti-rheumatic drugs, prednisone, TNF inhibitors, cholesterol lowering medications, and fish oil. The presence of enthesitis and/or dactylitis, irrespective of CDAI scores, was associated with abnormal TC, OR = 1.64; 95% CI: (1.08, 2.48); p = 0.02.

CONCLUSION

Our findings suggest an association between peripheral joint inflammation and lipid dysregulation in PsA. Further studies are needed to determine if treating PsA improves lipid profiles and cardiovascular mortality.

Burden of Moderate-to-Severe Plaque Psoriasis and New Therapeutic Approaches (Secukinumab): An Italian Perspective

Abstract

Psoriasis is a chronic immune-mediated inflammatory skin disease commonly categorized as mild, moderate, or severe. Moderate-to-severe psoriasis is associated with significant comorbidity and has been shown to severely impair quality of life. Moreover, psoriasis is associated with high costs, including those associated with treatment, which have increased recently with the inclusion of biological systemic agents (most recently secukinumab) as available treatment options. However, despite clear evidence of their value in the treatment of moderate-to-severe plaque psoriasis, in Italy access to the biological agents remains limited to dermatological centers originally involved in the Psocare network. The impact of secukinumab entry into the market in Italy is still to be determined, but we believe that it will be associated with significant changes in the way in which biological treatments for psoriasis are accessed and prescribed in Italy. It is noteworthy that in January 2015, the European Medicines Agency approved secukinumab as first-line systemic therapy in this indication.

Prevalence of metabolic syndrome as per the NCEP and IDF definitions vis-a-vis severity and duration of psoriasis in a semi-urban Maharashtrian population: A case control study

BACKGROUND

The inexorable inflammation in patients of psoriasis predisposes to various disorders, notably, a cluster of cardiovascular and metabolic abnormalities christened 'metabolic syndrome'.

AIM

To assess the prevalence of metabolic syndrome and its correlation with the severity and duration of psoriasis.

METHODS

One hundred psoriasis patients and 100 age-and-sex matched controls were included, whose waist circumference and blood pressure were measured; fasting serum cholesterol, triglycerides and glucose levels quantified; disease severity assessed and metabolic syndrome defined separately by two globally accepted criteria.

RESULTS

Metabolic syndrome (38%:12%), hypertriglyceridemia (53%:25%), impaired glucose tolerance (38%:16%) [P<0.001] and low HDL (P=0.002) were significantly more prevalent in cases as compared to controls as were the mean values of triglycerides and fasting blood sugar. Increased mean age of psoriasis patients and duration of disease strongly correlated with the presence of this syndrome. The divergence in definition of the syndrome by two separate criteria was also highly significant (P<0.001).

CONCLUSION

Metabolic syndrome had significant presence in and increased with the duration but remained unaffected by the severity of psoriasis in our study patients.

Chronic, not acute, skin-specific inflammation promotes thrombosis in psoriasis murine models

Background

Psoriasis patients exhibit an increased risk of atherothrombotic events, including myocardial infarction and stroke. Clinical evidence suggests that psoriasis patients with early onset and more severe disease have the highest risk for these co-morbidities, perhaps due to the extent of body surface involvement, subsequent levels of systemic inflammation, or chronicity of disease. We sought to determine whether acute or chronic skin-specific inflammation was sufficient to promote thrombosis.

Methods

We used two experimental mouse models of skin-specific inflammation generated in either an acute (topical Aldara application onto wild-type C57Bl/6 mice for 5 days) or chronic (a genetically engineered K5-IL-17C mouse model of psoriasiform skin inflammation) manner. Arterial thrombosis was induced using carotid artery photochemical injury (Rose Bengal-green light laser) and carotid artery diameters were measured post-clot formation. We also examined measures of clot formation including prothrombin (PT) and activated partial thromboplastin time (aPTT). Skin inflammation was examined histologically and we profiled plasma-derived lipids. The number of skin-draining lymph-node (SDLN) and splenic derived CD11b⁺Ly6C^high pro-inflammatory monocytes and CD11b⁺Ly6G⁺ neutrophils was quantified using multi-color flow cytometry.

Results

Mice treated with topical Aldara for 5 days had similar carotid artery thrombotic occlusion times to mice treated with vehicle cream (32.2 ± 3.0 vs. 31.4 ± 2.5 min, p = 0.97); in contrast, K5-IL-17C mice had accelerated occlusion times compared to littermate controls (15.7 ± 2.1 vs. 26.5 ± 3.5 min, p < 0.01) while carotid artery diameters were similar between all mice. Acanthosis, a surrogate measure of inflammation, was increased in both Aldara-treated and K5-IL-17C mice compared to their respective controls. Monocytosis, defined as elevated SDLN and/or splenic CD11b⁺Ly6C^high cells, was significantly increased in both Aldara-treated (SDLN: 3.8-fold, p = 0.02; spleen: 2.0-fold, p < 0.01) and K5-IL-17C (SDLN: 3.4-fold, p = 0.02; spleen: 3.5-fold, p < 0.01) animals compared to controls while neutrophilia, defined as elevated SDLN and/or splenic CD11b⁺Ly6G⁺ cells, was significantly increased in only the chronic K5-IL-17C model (SDLN: 11.6-fold, p = 0.02; spleen: 11.3-fold, p < 0.01). Plasma-derived lipid levels, PT and aPTT times showed no difference between the Aldara-treated mice or the K5-IL-17C mice and their respective controls.

Conclusions

Chronic, but not acute, skin-specific inflammation was associated with faster arterial thrombotic occlusion. Increased numbers of splenic and SDLN monocytes were observed in both acute and chronic skin-specific inflammation, however, increased splenic and SDLN neutrophils were observed only in the chronic skin-specific inflammation model. Understanding the cellular response to skin-specific inflammation may provide insights into the cellular participants mediating the pathophysiology of major adverse cardiovascular events associated with psoriasis.

A multileveled approach in psoriasis assessment and follow-up: A proposal for a tailored guide for the dermatological practice

BACKGROUND

Psoriasis is a complex and heterogeneous disease resulting from interactions between genetic, immunological, and environmental factors. To make the most optimal treatment decision, the dermatologist must therefore have a detailed overview of the patient's history and lifestyle.

OBJECTIVES

We sought to offer an overview of the various relevant aspects in clinical dermatological assessment of psoriasis patients, emphasizing the importance of a multidisciplinary and integrated clinical approach.

METHODS

We gathered information on psoriasis management and developed a tailored checklist covering all health-related aspects associated with psoriasis.

RESULTS

Demographics, personal and family history were elaborately described as well as drug history to discuss how they affect psoriasis management. Relevant patient information such as the vaccination status or cardiovascular profile were included in the checklist as well and treatment recommendations were adapted and updated in accordance with evidence-based literature. This checklist also emphasizes the importance of drug surveillance, proper follow-up and specialist referral, and why the dermatologist needs to address these health-related aspects when assessing psoriasis patients, going beyond optimal skin care.

CONCLUSIONS

Our comprehensive overview can be used as a consultation checklist for good clinical practice in psoriasis patient management and aid in treatment decision.

Role of C-reactive protein as a marker of disease severity and cardiovascular risk in patients with psoriasis

Background:

There is a paucity of studies addressing the elevation of C-reactive protein (CRP) among psoriatic patients and the role of this marker in assessment of disease severity and association with cardiovascular diseases (CVDs).

Objective:

To assess the difference in CRP levels between psoriatic patients and healthy population and to determine their role in disease severity. Also to compare CRP levels in psoriatic patients with and without the metabolic syndrome.

Materials and Methods:

A total of hundred patients with chronic plaque psoriasis and an equal number of age- and gender-matched healthy controls were enrolled in the study over a period of one year. Serum CRP levels of both cases and controls were estimated. Metabolic syndrome was identified among psoriasis patients using National Cholesterol Education Program's Adult Panel III (ATP III) guidelines. Clinical activity of psoriasis was evaluated using Psoriasis Area and Severity Index Score.

Results:

Patients with psoriasis reported significantly higher levels of CRP than healthy controls (P value 0.001). Patients with severe disease had significantly higher levels of CRP (P value < 0.003). Elevated level of CRP was observed among psoriatic patients with the metabolic syndrome than patients without the metabolic syndrome and the difference was statistically significant (P value = 0.001).

Conclusion:

CRP may be considered as a useful marker of psoriasis severity that could be used to monitor psoriasis and its treatment. Elevated levels of CRP may be an independent risk factor for CVD in patients with psoriasis.

Prevalence of cardiovascular disease risk factors, and metabolic syndrome and its components in patients with psoriasis aged 30 to 49 years

INTRODUCTION

Some studies show that metabolic syndrome (MS) is more common in psoriatic patients.

AIM

To evaluate the prevalence of MS and its components as cardiovascular disease (CVD) risk factors in psoriatic patients compared to the general Polish population.

MATERIAL AND METHODS

In 62 patients, aged 30 to 49 years with a mild to severe course of psoriasis, the features of MS have been assessed by IDF definition and compared to the results obtained in the NATPOL 2011 study.

RESULTS

Analysis of CVD risk factors in patients with a severe course of psoriasis showed a correlation with waist circumference (0.38, p < 0.05), hypertension (0.40, p < 0.05) and a negative correlation with HDL (0.29, p < 0.05). The prevalence of MS in psoriatic patients was 25.81%, and for the control group - 21.02% (p > 0.05), the mean HOMA-IR was 1.93 and 1.94 (p > 0.05), respectively. There were differences in the prevalence of abdominal obesity (53.6% vs. 40.3%, p < 0.05). In lipid parameters, except for HDL, the compared groups did not differ significantly (triglycerides, ApoA-I and B). Criteria for MS concerning blood pressure (> 130/85 mm Hg) and hypertension were more frequent in men with psoriasis than in the control group (38.2% vs. 11.1%, p < 0.05).

CONCLUSIONS

Severe psoriasis is associated with a significantly higher prevalence of risk factors for CVD. The prevalence of MS, insulin resistance and lipid abnormalities in patients with psoriasis aged 30 to 49 years is similar to the general Polish population. Abdominal obesity is more common in psoriatic patients and hypertension in men with psoriasis.

Prevalence of Obesity in Patients with Psoriasis: Results of the National Study PsoHealth3

BACKGROUND

Psoriasis is frequently associated with obesity which possibly contributes to reduced treatment response.

OBJECTIVES

Assessment of the prevalence of obesity in patients with psoriasis in Germany 2013/2014.

PATIENTS AND METHODS

The frequency of overweight and obesity was assessed by the body mass index (BMI) and evaluated according to the severity of psoriasis [Psoriasis Area and Severity Index (PASI)].

RESULTS

This national, cross-sectional survey involved 83 dermatological practices and outpatient clinics, including 1,265 patients (mean age 52 years; 43.4% female). The BMI of patients with psoriasis in 2013/2014 was found to be 28.0 and therefore was significantly higher compared to that of patients with psoriasis in 2007 with a BMI of 26.9 as well as compared to the normal population in 2013 with an overall BMI of 25.9.

CONCLUSIONS

The prevalence of obesity in patients with psoriasis is higher than in the normal population. The trend towards a higher BMI in patients with psoriasis continues over time.

Psoriasis is a systemic disease with multiple cardiovascular and metabolic comorbidities

There is evidence that patients with moderate to severe psoriasis have an increased risk of conditions such as cardiovascular disease, obesity, diabetes mellitus, and metabolic syndrome. The precise mechanisms underlying the observed increase in cardiovascular disease in psoriasis remain to be defined but inflammatory pathways mutual to both conditions are probably involved. Suppression of systemic inflammation in psoriasis could help reduce cardiovascular inflammation but robust evidence is still lacking evidence is lacking. This article summarizes the current literature on cardiovascular and metabolic comorbidities in psoriasis, identifies research gaps, and suggests management strategies to reduce cardiovascular risk in patients with moderate to severe psoriasis.

Influence of psoriasis on circulatory system function assessed in echocardiography

Psoriasis vulgaris is a chronic disease with a multifactorial pathogenesis. It affects about 2–4 % of the population all over the world. In course of psoriatic arthritis, joints’ damages are observed. In patients with psoriasis vulgaris and psoriatic arthritis, there is increased morbidity and mortality caused by cardiovascular diseases observed. The aim of the study is to analyze the echocardiography of patients with psoriasis vulgaris and psoriatic arthritis on the basis of the literature available in PubMed database. Abnormalities found in echocardiography of patients with psoriasis include valvular defects (40.7 % of the patients), left ventricle diastolic dysfunction (27.8 %), and left ventricle hypertrophy (11.1 %). Left ventricle’s systolic disorders, increased aorta stiffness index and increased pulmonary artery blood pressure were also observed in this group of patients.

Psoriasis vulgaris with or without arthritis and independent of disease severity or duration is a risk factor for hypercholesterolemia

BACKGROUND

Psoriasis (Ps) has been associated with an increased incidence of cardiovascular disease. Interesting epidemiological evidence suggests associations between Ps and dyslipidemia (DL), a well-established risk factor for cardiovascular disease.

OBJECTIVE

This study aimed to investigate the association between Ps and multiple measurements of DL, which include levels of triglycerides (TGs), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and total cholesterol (TCh). We also studied the relationship between DL and disease duration.

METHODS

A prospective hospital-based study was conducted. A total of 661 Caucasian patients with chronic plaque Ps and 661 sex- and age-matched controls were enrolled.

RESULTS

Multivariate analysis showed that in psoriatic patients the odds ratio (OR) of TCh >200 mg/dl was 1.406 (95% confidence interval 1.115-1.173), the OR of LDL cholesterol >130 mg/dl was 1.375 (95% confidence interval 1.088-1.738), the OR of HDL cholesterol <40 mg/dl was 0.881 (95% confidence interval 0.599-1.297), and the OR of TGs >150 mg/dl was 1.041 (95% confidence interval 0.783-1.385). We did not find a relationship between lipid levels and disease duration.

CONCLUSION

Based on our population Ps is associated with alterations in TCh and LDL cholesterol, but not in TGs and HDL cholesterol, when ATP III panel levels are used. These alterations are not related to disease duration.

Lipid profile and metabolic syndrome status in patients with oral lichen planus, oral lichenoid reaction and healthy individuals attending a dental college in northern India - a descriptive study

BACKGROUND

Chronic inflammation causes disturbances in the lipid metabolism. When this dyslipidemia becomes prolonged it increases the risk of cardiovascular disease. Recent literature reveals similar dyslipidemia in patients with lichen planus. However, the results were not compared with lichenoid reactions.

OBJECTIVE

The aim of this study was to profile the lipid levels and metabolic syndrome status in patients with oral lichen planus (OLP), oral lichenoid reactions (OLR) and healthy individuals in order to evaluate their respective cardiovascular risk.

MATERIALS AND METHODS

This case-control descriptive study included 32 adults from the OPD visiting the Department of Oral Medicine, 18 with either oral lichen planus or oral lichenoid reactions and 14 age and sex matched healthy controls. Ethical clearance and informed consent were obtained. Their lipid levels, body mass index and metabolic syndrome status were evaluated. Statistical analyses were performed with the SPSS version 16.0 software.P≥0.05 was considered significant.

RESULTS

The key findings of this study were a) increased levels of S.cholesterol and LDL-C in OLP and OLR patients when compared to normal healthy individuals b) significantly higher S.triglyceride and VLDL in OLP when compared to OLR and c) lower HDL-C levels in OLP when compared to OLR. 2(18%) patients with OLP and 3(50%) with OLR were found to have high BMI suggestive of obesity whereas none of the normal individuals were obese.

CONCLUSION

There may be an association between chronic inflammation and dyslipidemia that increases the risk for cardiovascular disease. OLP and OLR patients have increased serum cholesterol and LDL-C when compared to normal adults. Further research on lipid levels in OLR are required to establish the findings of this study.

Diet in dermatology: Part II. Melanoma, chronic urticaria, and psoriasis

The roles of dietary factors in aggravating, preventing, or treating skin diseases are common questions encountered in dermatology practice. Part II of this two-part series reviews dietary modifications that can potentially be utilized in the management of melanoma, chronic urticaria, and psoriasis patients. Specifically, we examine the effect of alcohol consumption and supplementation with vitamins D and E, polyunsaturated fatty acids, selenium, green tea, resveratrol, and lycopene on melanoma risk. The relationships between chronic urticaria symptoms and dietary pseudoallergens, gluten, and vitamin D are analyzed. We explore weight loss, reduced alcohol consumption, and gluten avoidance as means of reducing psoriasis-associated morbidity, as well as the possible utility of supplementation with polyunsaturated fatty acids, folic acid, vitamin D, and antioxidants. With proper knowledge of the role of diet in these cutaneous disease processes, dermatologists can better answer patient inquiries and consider implementation of dietary modifications as adjuncts to other treatments and preventative measures.

Pathogenic aspects of treatment of psoriatic patients

The article describes high incidence and morbidity rate of psoriasis, substantial reduction in the life quality and psychosocial disadaptation of patients, and presents certain particular features of psoriasis pathogenesis taking into consideration the role of immune mechanisms and relation between the disease and other chronic processes in the organism, as a result of which psoriasis is considered to be a multimorbid condition. The multimorbidity of psoriasis is an important factor for selecting a therapy, especially for patients with severe forms of the disease.

Dyslipidemia in Psoriasis: A Case Controlled Study

Multiple observational studies have demonstrated associations of psoriasis with metabolic syndrome including obesity, diabetes, hypertension, dyslipidemia, and osteoporosis. However there is paucity of Indian studies on dyslipidemia in psoriasis. The aim of this study was to assess the serum lipids in psoriasis and to investigate the association of lipids with disease severity and its duration. 100 cases of psoriasis (75/M, 25/F), between 15 and 72 years, were recruited with age and sex matched 73 controls. Using Psoriasis Area Severity Index (PASI) cases were graded into mild, moderate, and severe psoriasis. Serum total cholesterol and triglycerides were analyzed using enzymatic method. Using independent t-test, significant elevation of serum cholesterol, triglycerides, high density lipoprotein (HDL) and very low density lipoprotein was observed (P < 0.05) when compared to controls. The levels of low density lipoproteins were comparable in cases and controls. Lipid aberrations in hypertensive patients were significant. There was a decrease in HDL levels with increase in disease severity. A fall in the levels of HDL was seen in cases with long term psoriasis. There is a strong association of dyslipidemia with psoriasis. There exist racial and ethnic variation in the prevalence of psoriasis; however, dyslipidemia is consistently seen in diverse population. Whether genetic factors are implicated in lipid derangements in psoriasis needs further research.

Obesity and dyslipidemia in patients with psoriasis treated at a dermatologic clinic in Manaus

BACKGROUND

Psoriasis is a chronic inflammatory disease of multifactorial etiology, with participation of genetic, autoimmune and environmental factors. Recent studies have demonstrated the role of inflammatory cells and mediators in the pathogenesis of psoriasis, which is now defined as a systemic and autoimmune inflammatory disease that may be associated with other diseases of inflammatory nature.

OBJECTIVES

To evaluate the occurrence of obesity and dyslipidemia in patients with psoriasis treated at a dermatology clinic in Manaus.

METHODS

We performed a prospective descriptive study to assess the prevalence of obesity and dyslipidemia in patients with psoriasis. Besides the recommended dermatological care, a physical examination was performed to measure weight, height and waist circumference.

RESULTS

We included 72 patients, 44 (61.1%) female and 28 (38.9%) male, with a mean age of 51.0 years ± 15.9 years. As for body mass index (BMI), 16 (22.2%) were overweight and 20 (27.8%) were obese. In the analysis of waist circumference in relation to gender, we found that 79.5% of women surveyed had central obesity, a percentage statistically higher than that observed among men (42.9%) at the 5% level of significance (p = 0.001). Regarding the diagnosis of dyslipidemia, 29 (65.9%) females and 22 (78.6%) males showed alterations in lipid profile.

CONCLUSIONS

The occurrence of dyslipidemia and obesity in patients with psoriasis can affect life quality and expectancy, increasing the risk of systemic and metabolic diseases, which makes periodic investigation of these comorbidities in patients with psoriasis mandatory.
