[PMID: 37049545 PMCID: PMC10097110 DOI: 10.3390/nu15071705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 03/17/2023] [Accepted: 03/29/2023] [Indexed: 04/03/2023] Open
Abstract
Psoriasis is an immune-mediated inflammatory systemic disease with skin tropism and chronic relapsing course; it is associated with an increased cardiovascular risk and with many metabolic comorbidities, emerging during childhood in 22–33% of cases. Diet influences the presentation and the clinical course of inflammatory diseases, including psoriasis; in particular, it was shown that a Mediterranean, gluten-free, or low-calorie diet may positively affect disease control in adult patients with psoriasis and adequate pharmacological therapy. These three dietary regimens may play a role also in children with psoriasis. It has been demonstrated that pediatric psoriasis is associated with psychological stress, celiac disease, and obesity, which may be positively influenced by these dietary regimens, respectively. Therefore, the expertise of multiple health figures (gastroenterologists, nutritionists, pediatricians, dermatologists) is required to plan a tailor-made dietary strategy, ensuring good growth, through an adequate intake of essential micro- and macronutrients and, at the same time, impacting the pro-inflammatory biochemical profile and on the associated cardiovascular risk of psoriasis disease.

Abstract
Psoriasis is a chronic systemic inflammatory disease that primarily affects the skin and is associated with multiple comorbidities with a considerable reduction in quality of life of affected patients. One-third of psoriasis cases begin in childhood and are associated with significant medical comorbidities such as obesity, metabolic syndrome, arthritis, and psychiatric disorders. In addition, because of its chronic nature and frequent relapses, psoriasis tends to require long-term treatment. Treatment of pediatric psoriasis usually involves the same methods used for adults. However, most treatments for pediatric psoriasis are used off-label, and research in this regard is still lacking. Targeted therapies involving the use of newly developed biologic drugs are also increasingly being applied to childhood psoriasis. This review summarizes the clinical features of pediatric psoriasis and focuses mainly on the updated concepts of pathogenesis and biological treatments of pediatric psoriasis.

Abstract
Psoriasis vulgaris is a common inflammatory, immune mediated, chronic recurrent dermatosis. Psoriasis is also a systemic inflammatory disease, associated with numerous comorbidities, particularly metabolic ones. Here, we summarize and discuss, in a narrative review, the current knowledge about the metabolic comorbidities in psoriatic children. Obesity, insulin resistance, diabetes, cardiovascular disease, and dyslipidemia are identified as the main comorbidities in psoriatic children. In conclusion, dermatologists should be aware of the metabolic comorbidities in children with psoriasis, modulating the therapeutic approach according to the patient’s clinical condition.

Abstract
Background: previous studies reported the involvement of reactive oxygen species (ROS) and lipid peroxidation in the pathogenesis of inflammatory skin diseases. The aim of our study was to investigate the relationship between oxidative stress and inflammation in children affected by atopic dermatitis (AD), a chronic relapsing inflammatory skin disease. Methods: levels of lipid hydroperoxides, total antioxidant capacity, and activities of the enzymes myeloperoxidase (MPO), PON1, and PON2/3 were investigated in 56 atopic pediatric patients, and compared with 48 sex-/age-matched healthy controls. Results: significantly higher levels of lipid hydroperoxides and lower values of total antioxidant potential were observed in the serum of AD children compared to that of the controls. Significant lower PON1 activities, and a significant increase in levels of MPO were observed in serum of patients, with a higher serum MPO level/PON1 paraoxonase activity ratio in patients compared to that in the controls. Significantly lower lactonase activity of PON enzymes was observed in polymorphonuclear cells isolated from AD patients. Statistically negative correlation was established between the activity of intracellular PON2/3 activity and ROS levels. Conclusions: our data confirmed that AD is associated with higher oxidative damage and a decrease in antioxidant defense. Moreover, alterations of extracellular and intracellular PON activity can promote lipoprotein dysfunction in AD patients.

High-Density Lipoprotein (HDL) in Allergy and Skin Diseases: Focus on Immunomodulating Functions. Biomedicines 2020; 8:biomedicines8120558.

Abstract
From an evolutionary perspective, lipoproteins are not only lipid transporters, but they also have important functions in many aspects of immunity. High-density lipoprotein (HDL) particles are the most abundant lipoproteins and the most heterogeneous in terms of their composition, structure, and biological functions. Despite strong evidence that HDL potently influences the activity of several immune cells, the role of HDL in allergies and skin diseases is poorly understood. Alterations in HDL-cholesterol levels have been observed in allergic asthma, allergic rhinitis, atopic dermatitis (eczema), psoriasis, urticaria, and angioedema. HDL-associated apolipoprotein (apo) A-I, apoA-IV, and apoC-III, and lyso-phosphatidylcholines potently suppress immune cell effector responses. Interestingly, recent studies provided evidence that allergies and skin diseases significantly affect HDL composition, metabolism, and function, which, in turn, could have a significant impact on disease progression, but may also affect the risk of cardiovascular disease and infections. Interestingly, not only a loss in function, but also, sometimes, a gain in function of certain HDL properties is observed. The objective of this review article is to summarize the newly identified changes in the metabolism, composition, and function of HDL in allergies and skin diseases. We aim to highlight the possible pathophysiological consequences with a focus on HDL-mediated immunomodulatory activities.

Abstract
BACKGROUND/OBJECTIVES There is an increasing volume of evidence which supports the link between psoriasis and cardiometabolic risk including obesity, metabolic syndrome, diabetes, hyperlipidemia, and myocardial infarction. Although one-third to one-half of psoriasis cases start during childhood, it is unclear whether childhood psoriasis is similarly associated with a cardiometabolic risk profile. METHODS Electronic database searches were performed to identify studies comparing the proportion of pediatric psoriasis cases with controls in terms of dichotomous outcomes including the proportion of patients with overweight BMI, obese BMI, metabolic syndrome, diabetes, hypertension, hyperlipidemia, ischemic heart disease, or heart failure; continuous outcomes recorded include BMI, systolic blood pressure, diastolic blood pressure, HDL, LDL, triglycerides, and total cholesterol. RESULTS A statistically significant association was found between pediatric psoriasis and overweight/obesity as well as waist:height ratio >0.5, in addition to metabolic syndrome, diabetes, hyperlipidemia, hypertension, and cardiac ischemia and failure. The association with obesity is dependent on the severity of disease, where moderate-severe psoriasis patients have higher odds of obesity compared to mild psoriasis. CONCLUSIONS Our systematic review and pooled meta-analysis demonstrate a significant association between childhood psoriasis and obesity, central adiposity, and other cardiometabolic comorbidities. Clinicians should consider the assessment of comorbidities in children with psoriasis, which may allow for early lifestyle interventions and education.

Abstract
BACKGROUND Similarly to psoriasis in adults, recent research has linked psoriasis to several comorbidities in children. The aim of this study was therefore to describe comorbidities associated with pediatric psoriasis, to investigate their relationship with psoriasis characteristics and severity, and to perform a review of the literature. METHODS A cross-sectional study was performed on a sample of Moroccan children with psoriasis, in 2014-2016. RESULTS A total of 64 pediatric psoriasis patients had metabolic comorbidities in association with psoriasis; 20 children had non-metabolic comorbidities; and 76 children had no comorbidity. The metabolic comorbidities were as follows: abdominal obesity, 40% (n = 64); overweight, 12.5% (n = 20); metabolic syndrome, 3.7% (n = 6); and dyslipidemia, 3.1% (n = 5); the non-metabolic comorbidities were atopy, 4.3% (n = 7); epilepsy, 3.1% (n = 5); celiac disease, 1.8% (n = 3); vitiligo, 1.8% (n = 3); alopecia ariata, 0.6% (n = 1); and valvular cardiopathy, 0.6% (n = 1). No cases of diabetes mellitus, obesity, or high blood pressure were recorded. Significant factors associated with metabolic comorbidity were extended psoriasis vulgaris >10% (P = 0.01; OR, 2.19), severe psoriasis especially pustular and erythroderma (P = 0.018; OR, 2), nail involvement (P = 0.016; OR, 1.5), face involvement (P = 0.01; OR, 1,59), resistance to topical treatment (P = 0.003; OR, 2.5) and alteration of quality of life (P = 0.02; OR, 1,7). There was no significant risk factor associated with non-metabolic comorbidity. CONCLUSIONS Given the frequent association of pediatric psoriasis with many disorders, these comorbidities should be investigated and identified so that they can be taken into account in the management of psoriasis in order to avoid treatment failure. Regular follow up should be carried out in patients at risk of metabolic comorbidity.

J Invest Dermatol 2016; 136:67-73.

Abstract
Psoriasis is associated with increased cardiovascular disease in adults, but the risk profile of children with psoriasis remains to be fully characterized. We measured lipoprotein composition and function in 44 patients with pediatric psoriasis and 44 age- and sex-matched healthy controls, using nuclear magnetic resonance spectroscopy and a validated ex vivo assay of high-density lipoprotein cholesterol efflux capacity. The mean age of the patients was 13 years and the population was ethnically diverse. Children with psoriasis had higher waist-to-hip ratios (0.85 vs. 0.80; P < 0.002) and insulin resistance measures (log-transformed homeostasis model assessment of insulin resistance 0.65 vs. 0.41; P = 0.07). Despite comparable traditional lipid values, having psoriasis was associated with higher apolipoprotein B concentrations (72.4 vs. 64.6; P = 0.02), decreased large high-density lipoprotein particles (5.3 vs. 6.7; P < 0.01), and reduced cholesterol efflux capacity after adjusting for age, sex, fasting glucose, homeostasis model assessment of insulin resistance, systolic blood pressure, body mass index, apolipoprotein A-1, and high-density lipoprotein cholesterol concentration (β -0.22; P = 0.02). Patients with pediatric psoriasis have a more atherogenic cardiometabolic risk profile, with evidence of insulin resistance and lipoprotein dysfunction by particle size, number, and functional assessment. These findings may provide a basis for the observed link later in life between psoriasis and cardiovascular disease, and support the need to screen and educate young patients to minimize later complications.

Abstract
Psoriasis is a common disease with the population prevalence ranging from 2% to 3%. Its prevalence in the population is affected by genetic, environmental, viral, infectious, immunological, biochemical, endocrinological, and psychological factors, as well as alcohol and drug abuse. In the recent years, psoriasis has been recognised as a systemic disease associated with numerous multiorgan abnormalities and complications. Dyslipidemia is one of comorbidities in psoriatic patients. Lipid metabolism studies in psoriasis have been started at the beginning of the 20th century and are concentrated on skin surface lipids, stratum corneum lipids and epidermal phospholipids, serum lipids, dermal low-density lipoproteins in the psoriatic skin, lipid metabolism, oxidative stress and correlations between inflammatory parameters, lipid parameters and clinical symptoms of the disease. On the basis of the literature data, psoriasis can be described as an immunometabolic disease.

Abstract
Objective.Patients with psoriasis and psoriatic arthritis (PsA) have an increased incidence of cardiovascular disease (CVD) and cardiovascular risk factors such as smoking, hypertension, and metabolic syndrome compared to the normal population. Patients with psoriasis and PsA may also have increased risk from nonconventional risk factors such as raised levels of homocysteine and excessive alcohol consumption. We conducted a comprehensive review of the literature on CVD and all cardiovascular risk factors in patients with psoriasis and PsA.Methods.Data sources: All studies identified from a Medline (www.ncbi.nlm.nih.gov) search pertaining to CVD, individual risk factors in psoriasis, and PsA were included. Study selection: Studies included a healthy reference population, were published between 1975 and 2009, and were written in English.Results.Our search yielded 14 studies that documented rates of CVD in patients with psoriasis and PsA compared to controls. Substantial evidence points to elevated risk of CVD in patients with psoriasis and PsA.Conclusion.It remains difficult to conclude if risk factors are caused by psoriasis or share a common pathogenesis. Physicians treating patients with psoriasis and PsA must be aware of all potential cardiovascular risk factors in their patients.

Abstract
Psoriasis is one of the common complex disorders in Western world, affecting 2% to 3% of the population. Recent studies indicate that psoriasis is associated with an increased risk of comorbidity and mortality compared to the general population. It appears that patients with psoriasis have a higher prevalence of metabolic disorders such as diabetes, hypertension, obesity, and hyperlipidemia, as well as a higher frequency of cigarette smoking. These concomitant diseases can complicate the treatment of psoriasis. Even though the etiology of these associations is elusive, physicians should be aware of them and take active steps to reduce the risk profiles of patients with psoriasis and psoriatic arthritis, in order to lessen mortality and comorbidity.

Abstract
Psoriasis is characterized by defects in the normal cycle of epidermal development that lead to epidermal hyperproliferation, altered maturation of skin cells, vascular changes and inflammation. Also, psoriasis has been associated with an abnormal plasma lipid metabolism. Changes in plasma lipid and lipoprotein composition in patients with psoriasis may be the reason for the increased risk of atherosclerosis in these patients. We determined serum concentrations of lipids, lipoproteins and apolipoprotein Al and B (apo A1 and apo B) in 72 patients with psoriasis and 30 age matched controls. Serum lipoprotein (a) (Lp(a)), apo A1 and apo B were measured by immunoprecipitation assays, and the lipids and other biochemical parameters by enzymatic methods. Serum Lp(a) and triglyceride (TG) were significantly higher in patients with psoriasis than in healthy control subjects (p<0.01 for both). Apo B was also found to be higher in the patient group, but the difference was not significant. The levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and apo A1 did not differ significantly from those of the controls. These observations imply that serum Lp(a) and TG concentrations may play a role as risk factors for atherosclerotic disease in patients with psoriasis.

Abstract
Psoriasis is a common chronic and recurrent inflammatory skin disorder that has been associated with oxidative stress, abnormal plasma lipid metabolism and with high frequency of cardiovascular events. This prevalence seems to be related to the severity of psoriasis, as it occurs more frequently in patients presenting large areas of the body affected with psoriasis lesions. The aim of our work was to evaluate the development of oxidative stress and of dislipidemia in psoriasis, and to look for a correlation between their levels and worsening of psoriasis. We evaluated lipid profile, total antioxidant capacity, antioxidant vitamins A and E, and lipoperoxidation products. The study was performed in controls and in patients presenting mild and severe psoriasis. Patients presented risk changes in lipid profile (a rise in cholesterol (P<0.01), triglycerides (P<0.001), low density lipoprotein cholesterol (P<0.01), very low density lipoprotein cholesterol (P<0.01), apolipoprotein B (P<0.001) and lipoprotein(a) (P<0.001); and a reduction in high density lipoprotein cholesterol (P<0.001)), a rise in lipoperoxidation products (P<0.001) and a reduction in total antioxidant capacity (P<0.001) and in antioxidant vitamins A (P<0.001) and E (P<0.05). Moreover, we found that the worsening of psoriasis was associated with the enhancement of oxidative stress and of the lipid risk changes. Our data suggest that psoriasis patients must be considered as a group at risk for cardiovascular disease and that this risk seems to be higher in severe psoriasis. In addition, a possible benefit of an enriched diet or of a supplement of vitamins A and E in psoriasis patients should be further studied.

Abstract
BACKGROUND Na+,K(+)-ATPase activity was evaluated in relation to membrane composition and molecular organization in erythrocyte membranes from obese patients by the amphyphylic molecule 6-dodecanoyl-2-dimethylamino-naphthalene (Laurdan). Its possible relationship with fat distribution and hyperinsulinaemia was also investigated. DESIGN Subjects were 10 obese men (OM), 12 women with subcutaneous obesity (FSO), 10 women with abdominal obesity (FAO) and 41 healthy lean subjects, 26 women (FC) and 15 men (MC). An oral glucose tolerance test was administered to all subjects to evaluate insulin secretion and glucose tolerance. RESULTS Na+,K(+)-ATPase activity was increased in all obese patients. Values were higher in FSO and FAO than in FC (with FAO greater than FSO) and in OM than in MC. The erythrocyte membrane cholesterol-to-phospholipid ratio was increased in obese patients and was significantly different in FSO patients compared with FC. The erythrocyte membrane protein-to-phospholipid ratio was also increased in all obese subjects, reaching statistical significance only in FSO vs. FC. The liquid crystalline phase, as tested by Laurdan generalized polarization (GP), was decreased in obese patients, indicating the presence of greater molecular environmental order; all patients groups showed lower GP values than control subjects, but only FAO reached statistical significance compared with FC. There was no evident correlation between membrane Na+,K(+)-ATPase activity and insulin levels, nor did membrane composition and properties show any evident relationship with insulin levels. CONCLUSION Both increased Na+,K(+)-ATPase activity and altered fluidity and lipid composition were observed in the erythrocyte membrane of all obese patients. These findings are in line with previous observations by our group and indicate that the changes in Na+,K(+)-ATPase activity observed in obese patients could be related to changes in plasma membrane organization and composition.
