Abstract
Background: Psoriatic patients tend to develop metabolic syndrome (MS). MS accelerates psoriasis, but the exact molecular mechanisms are poorly understood.Objectives: We aim to investigate the impact of leptin on keratinocyte insulin sensitivity and explore its underlying molecular mechanism, which might play a role in the pathogenesis of this disease.Methods: ELISA and immunohistochemistry were applied respectively to detect the level of leptin in serum and in lesion of psoriatic patients with and without MS. The HaCaT cell line was cultured and western-blot assay was performed to assess the change of insulin sensibility. q-PCR and western-blot assay were applied to detect the SOCS3 expressions. Knockdown of SOCS3 were generated in HaCaT cell line by siRNA. Leptin and insulin were treated for 6 days and K10 expression was evaluated by western-blot assay.Results: Patients with MS had higher level of leptin in serum and lesions than their counterparts without MS. Serum levels of leptin was negatively correlated to PASI decline index in psoriatic patients. Long-term treatment of leptin induced insulin resistance in HaCaT cell line, as indicated by elevated expression of p-IRS-1 (ser636) and lower p-PKB (ser473). Leptin treatment up-regulated the mRNA and protein expression of SOCS3. Knockdown of SOCS3 blocked the effect of leptin-induced insulin resistance. Leptin treatment attenuated insulin-elicited K10 expression.Conclusions: Leptin induces insulin resistance by upregulating SOCS3 and give rise to differentiation disorder of keratinocyte. Insulin resistance may serve as a target for anti-psoriatic therapies.

Circadian Oscillations of Minimal Erythema Dose (MED) are Also Influenced by Diet in Patients with Psoriasis: A Chronomedical Study. Dermatol Ther (Heidelb) 2023; 13:2229-2246. [PMID: 37573289 PMCID: PMC10539244 DOI: 10.1007/s13555-023-00987-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Accepted: 07/17/2023] [Indexed: 08/14/2023] Open
Abstract
INTRODUCTION Minimal erythema dose (MED) remains a parameter of paramount importance to orient narrow-band (NB)-UVB phototherapy in psoriatic (PsO) patients. Recently, circadian rhythm and diet were recognized as potential MED modulators, but their mutual interaction remains understudied. Thus, we aimed to evaluate the potential diet modulation of MED circadian oscillations. METHODS In the first phase, a cohort study was performed comparing potential MED oscillations (morning, afternoon, and evening) among omnivorous psoriatic patients before and after a phototherapy cycle and omnivorous healthy controls. The two groups were age-, gender-, skin-type-, MED-, and diet-matched. Then, in the second phase, another cohort study was carried out comparing MED oscillations 24 h after the last phototherapeutic session only in psoriatic patients cleared with NB-UVB and undergoing different diets (vegan, vegetarian, paleo , ketogenic, intermittent circadian fasting, and omnivore). Patients with different diets were age-, gender-, and skin-type matched. RESULTS In the first phase, we enrolled only omnivores, specifically 54 PsO patients and 54 healthy individuals. Their MED before and after NB-UVB therapy changed significantly among the three different time-points (morning, afternoon, and evening) (p < 0.001). The time effect was statistically significant in both groups before and after phototherapy. In the second phase, we enrolled 144 PsO patients (vegan, vegetarian, paleo, ketogenic, intermittent circadian fasting, and omnivore). MED circadian oscillations preserved a significant difference also after clearance and were influenced by diet type and time of day (p < 0.001). In particular, vegans displayed the lowest MED values, whilst Ramadan fasting showed the highest values in morning, afternoon, and evening. CONCLUSIONS Diet, like other ongoing therapies, should be reported in the medical records of patients with psoriasis undergoing NB-UVB and patients with lower MEDs should be preferentially treated in the morning when the MED is higher.

Abstract
Metabolic syndrome is currently considered to be a global epidemic, causing a significant increase in the cost of health care, apart from deteriorating the quality of life. Skin serves as a mirror of underlying metabolic sinister. Various dermatological conditions like psoriasis, acanthosis nigricans, lichen planus, acne vulgaris, acrochordons, atopic dermatitis, etc. have been reported to be associated with metabolic syndrome. We hereby present an evidence-based review of the various dermatological conditions and their association with the development of metabolic syndrome.

Abstract
Psoriasis (PS) is an incessant, fiery skin sickness characterized by erythematous plaques with thick silvery scales, white or red patches of the skin, which encompasses several immunological, biomolecular, genetic, and environmental factors that may lead to further development of metabolic syndrome (MS) and vice versa. Metabolic syndrome is composed of multiple components (high blood pressure, abdominal obesity, glucose intolerance, and dyslipidemia) of risk factors that arise primarily from insulin resistance, mostly mediated by inflammatory cytokines, such as tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6) together with leptin and adiponectin, which are molecules also found in PS. The incidence, severity, and poor prognosis of the psoriatic diseases could be influenced by cardiometabolic diseases, which are controllable or preventable with intense lifestyle modification such as diet, exercise, and weight control. We performed a far-reaching writing search of different databases as part of this review; 47 investigations were regarded as important based on our search. Fasting, proper weight management, and special diet modifications seemed to have a positive impact on the management of PS. This review agrees with previous literature that nutritionists and specialists of preventive medicine should play a central role in the evaluation and management of psoriatic patients. We recommended that the management of this disease should focus on the environmental factors first instead of the genetic and immunologic pathways.

Abstract
Emerging findings suggest that exposure to ultraviolet wavelengths of sunlight modulates metabolic function. Here we review the metabolic effects of exposure to ultraviolet radiation (UVR), focusing on the effects of phototherapies (that administer UVR), and advice to increase sun exposure in individuals enrolled in clinical trials and intervention studies. We identified 25 studies in which the effects of UVR on metabolic outcomes were examined, including: narrowband ultraviolet B phototherapy (nbUVB, n = 12); psoralen ultraviolet A phototherapy (n = 4); other types of UVR phototherapy (n = 5); and sun exposure advice (n = 5). Most studies recruited a small number of participants (≤100), who were middle-aged individuals undergoing treatment for psoriasis flare, with phototherapy or sun exposure advice administered for ≤12 weeks. Data obtained at baseline were usually compared with an endpoint following treatment with UVR, for a limited number of outcomes. There were few studies in which markers of glucose metabolism were assessed, with some beneficial effects of sun exposure (but not phototherapy) reported. LDL-cholesterol levels were lower in individuals receiving sun exposure advice, while treatment with nbUVB reduced blood concentrations of inflammatory markers (C-reactive protein and interleukin-6). Future studies should focus on determining whether the effects of these interventions change with time, and if they are dependent on the source of UVR (i.e. phototherapy or sun exposure) and wavelength(s) of light administered. Furthermore, studies need to measure a variety of (clinical) markers of glucose metabolism, adiposity and inflammation, control for factors such as skin type and sex, and stratify participants for metabolic disease diagnosis.

Abstract
Psoriasis is a common chronic inflammatory multisystemic disease with a complex pathogenesis consisting of genetic, immunological, and environmental components. It is associated with a number of comorbidities, including diabetes, metabolic syndrome, obesity, and myocardial infarction. In addition, the severity of psoriasis seems to be related to the severity of obesity. Patients with higher levels of obesity show poorer response to systemic treatments of psoriasis. Several studies have demonstrated that white adipose tissue is a crucial site of the formation of proinflammatory adipokines such as leptin, adiponectin, and resistin and classical cytokines such as interleukin- (IL-) 6 and tumour necrosis factor-α. In psoriasis, due to the proliferation of Th1, Th17, and Th22 cells, IL-22, among others, is produced in addition to the abovementioned cytokines. With respect to leptin and resistin, both of these adipokines are present in high levels in obese persons with psoriasis. Further, the plasma levels of leptin and resistin are related to the severity of psoriasis. These results strongly suggest that obesity, through proinflammatory pathways, is a predisposing factor to the development of psoriasis and that obesity aggravates existing psoriasis. Different inflammatory biomarkers link psoriasis and obesity. In this paper, the most important ones are described.

Abstract
Psoriasis is an immune-mediated disease where the IL-23/Th17 axis as well as TNF comprise main targets of biological therapy. Immune profiling has so far not been embraced as a clinical tool. We aimed to investigate relationships between individual serum cytokine levels in 40 psoriasis patients before and after receiving biological therapy and Psoriasis Area and Severity Index (PASI) and Dermatological Life Quality Index (DLQI). Serum concentration of 25 cytokines was determined by Luminex technology. Mean PASI and DLQI decreased by 71% and 65%, respectively. Increase of IL-2 positively correlated with improvement of PASI and DLQI. Moreover, increase of IL-5, IL-10, IL-12, IL-22 and GM-CSF correlated with treatment effect. Notably, logistic regression revealed four times higher risk of having severe psoriasis when IL-17A increased by 1 pg/mL (OR: 4.06, P < 0.05). Selected serum cytokines might constitute useful biomarkers for monitoring disease activity and optimizing therapeutic strategies in psoriasis patients.
