Abstract
PURPOSE The etiology of alopecia areata (AA) in relation to serum lipids remains unclear, thereby prompting our intention to do Mendelian study on this subject. DESIGN Two-sample Mendelian randomization (MR) analysis was performed in the study. The inverse variance-weighted method was used as the primary method. METHODS In our study, we integrated a set of 123 single-nucleotide polymorphisms (SNPs) into our analysis. These SNPs have been extensively studied and are known to exhibit associations with serum lipids. We sourced these SNPs from a variety of relevant studies and consortia that specifically focus on lipid-related research, such as the MRC Integrative Epidemiology Unit. These carefully curated SNPs were then utilized as instrumental variables in our analysis, allowing us to explore and evaluate the causal relationships between these genetic variants and serum lipids. By incorporating this comprehensive set of SNPs, we aimed to enhance the precision and robustness of our findings, shedding light on the intricate interplay between genetics and serum lipids. RESULTS In the MR analysis, a higher total lipid concentration in large low-density lipoprotein (LDL) particles (odds ratio [OR] = 1.502; 95% confidence interval [CI] = 1.086-1.953; p = 0.006), a greater ratio of cholesteryl esters to total lipids in chylomicrons and extremely large very LDL (VLDL) particles (OR = 2.174; 95% CI = 1.300-2.500; p = 0.010), and a greater ratio of cholesterol to total lipids in chylomicrons and extremely large VLDL particles (OR = 2.363;95% CI = 1.556-4.438; p = 0.004), were genetically predicted to be causally associated with an increased risk of AA, while patients with a higher triglyceride to total lipids ratio in chylomicrons and extremely large VLDL particles had a lower risk of AA (OR = 0.481; 95% CI = 0.191-1.270; p = 0.002). CONCLUSION This study found that serum lipids may be causally implicated in AA.

Abstract
PURPOSE Graves orbitopathy (GO) is the most common extrathyroidal manifestation of Graves disease. Although its pathogenesis is not fully elucidated, GO is commonly considered an autoimmune disease due to loss of self-tolerance against autoantigens shared by thyroid epithelial cells and orbital fibroblasts. High-dose intravenous glucocorticoids (ivGCs) are the most used treatment for moderate-to-severe, active GO, but the addition of other immunomodulating treatments can improve the efficacy of ivGCs. Among the various risk factors that can affect the occurrence of GO, cholesterol may be worthy of interest. Since 2015 the role of cholesterol and cholesterol-lowering medications has been investigated. The purpose of this review is to discuss this topic, thereby offering new therapeutic opportunities for patients with GO. METHODS We searched PubMed for studies published between January 1, 1980 and June 1, 2023, using the search terms "Graves orbitopathy," "thyroid eye disease," "Graves ophthalmopathy," "thyroid ophthalmopathy," "thyroid-associated ophthalmopathy," "endocrine ophthalmopathy," "cholesterol," "lipids," "statins," "low-density lipoprotein," "atorvastatin," and "cholesterol-lowering drugs." Only English-language articles were included. RESULTS A correlation between low-density lipoprotein cholesterol and the risk of GO development has been reported. Furthermore, low-density lipoprotein cholesterol has been proposed as a risk factor that can affect the course of GO and the response to ivGCs. The protective role of cholesterol-lowering medications in preventing GO has been also investigated. Statin treatment was found to have potential benefits in reducing the risk of GO in patients with Graves disease. Given these findings, measurement of low-density lipoprotein cholesterol and treatment of hypercholesterolemia in patients with moderate-to-severe, active GO may be considered before starting ivGCs administration. Recently, a randomized clinical trial aimed at investigating the effects of statins in GO suggested that the addition of oral atorvastatin to ivGCs improves the overall outcome of moderate-to-severe, active GO in hypercholesterolemic patients given ivGCs. CONCLUSIONS Overall, statins seem to have a preventive and therapeutic role in moderate-to-severe active GO. Their efficacy can be related to cholesterol-lowering activity, pleiotropic actions, and interaction with methylprednisolone.

Abstract
Psoriasis is a chronic inflammatory skin condition, with genetic, epigenetic, environmental, and lifestyle factors contributing to its onset and recurrence. Severe psoriasis has a great impact on quality of life, which is similar to that of insulin-dependent diabetes, depression, and ischemic heart disease, but with a lower mortality. There is an overlap between the rising incidences of autoimmune diseases and obesity. In recent years, research has shown that there is an association between psoriasis and obesity. Psoriasis is linked to obesity in a two-way manner, as each can precipitate the development of the other. Several adipose tissue-secreted adipokines were shown to be elevated in obese psoriasis patients, exhibiting similar mechanisms of action to those underlying the pathogenesis of psoriasis. Excess body weight can influence not only the treatment response in psoriasis, but also the adverse events, leading to decreased patient compliance. Specific human microbiome patterns have been identified for obesity and psoriasis and could represent a future therapeutic target in selected individuals.

Abstract
BACKGROUND Psoriasis is a chronic inflammatory immune-mediated and hyper proliferative skin disorder that has underlying genetic factors. Psoriasis can result from interaction of cytokines between keratinocytes and T-lymphocytes. NEAT is a lncRNA involved in immune modulation and has been previously studied in cancers. This study aims to clarify the unprecedented role of NEAT in psoriasis pathogenesis. METHODS The study was conducted on 50 healthy control subjects and 50 psoriasis patients. Blood samples from all participants were collected for analysis of their lipid profile. qRT-PCR was done for lncRNA NEAT, TNF-α, VEGF genes expression. The levels of ROS and caspase-3 were estimated by ELISA. ROC analysis was done to detect the diagnostic value of lncRNA NEAT gene expression. RESULTS Dyslipidemia is more prevalent among psoriasis patients. A significant up regulation in lncRNA NEAT, TNF-α, VEGF genes expression (p value˂0.001) in psoriasis patients in addition to significant increase in ROS and caspase-3 levels (p value˂0.001) in compare to controls. Additionally, a positive significant correlation between TNF-α, ROS, NEAT, caspase-3 and dyslipidemia. NEAT had an area under the curve (AUC) of 0.931 (95% CI 0.844-0.978, p < 0.001). CONCLUSION Dyslipidemia is an initiating signal in psoriasis pathogenesis that creates a state of chronic inflammation and oxidative stress. This state induces keratinocytes proliferation and release of NEAT with subsequent caspase-3 activation to counteract the proliferating cells. NEAT could be considered as a good diagnostic biomarker for psoriasis.

Abstract
BACKGROUND Energy is the currency of life. The systemic and intracellular energy metabolism plays an essential role for the energy supply of the resting and activated immune system and this also applies to chronic inflammatory diseases. OBJECTIVE This presentation examines both components of the systemic and cellular energy metabolism in health and chronic inflammation. MATERIAL AND METHODS A literature search was conducted using PubMed, Embase and the Cochrane Library. The information is presented in the form of a narrative review. RESULTS A chronically activated immune system acquires large amounts of energy-rich substrates that are lost for other functions of the body. In particular, the immune system and the brain are in competition. The consequences of this competition are many known diseases, such as fatigue, anxiety, depression, anorexia, sleep problems, sarcopenia, osteoporosis, insulin resistance, hypertension and others. The permanent change in the brain causes long-term alterations that stimulate disease sequelae even after disease remission. In the intracellular energy supply, chronic inflammation typically involves a conversion to glycolysis (to lactate, which has its own regulatory functions) and the pentose phosphate pathway in disorders of mitochondrial function. The chronic changes in immune cells of patients with rheumatoid arthritis (RA) lead to a disruption of the citric acid cycle (Krebs cycle). The hypoxic situation in the inflamed tissue stimulates many alterations. A differentiation is made between effector functions and regulatory functions of immune cells. CONCLUSION Based on the energy changes mentioned, novel treatment suggestions can be made in addition to those already known in energy metabolism.

Abstract
BACKGROUND Newer biologics, such as interleukin (IL)-17 inhibitors, make it possible to achieve complete skin clearance (CSC) in patients with moderate-to-severe psoriasis. However, the clinical meaningfulness and predictive factors of CSC in daily practice have not yet been fully investigated. OBJECTIVE The study was conducted to, first, assess the impact of CSC on quality of life (QoL) improvements compared with treatment responses without clearance and, second, identify clinical parameters as predictors of CSC response in psoriasis patients treated with ixekizumab. METHODS Patients attending 26 dermatology centers across China were recruited into this real-world setting between August 2020 and May 2022. Prospective cohort study in which response to ixekizumab was assessed using the Psoriasis Area and Severity Index (PASI) and Dermatology Quality of Life Index (DLQI). The absolute DLQI score and DLQI (0) response at week 12 were compared between groups achieving various levels of skin clearance. A stepwise logistic regression analysis was applied to identify which baseline clinical characteristics were predictive factors for CSC. RESULTS After 12 weeks of treatment, 226 of 511 (44.2%) patients achieved CSC, defined as 100% improvement in PASI score (PASI-100). A significantly higher proportion of patients with CSC versus almost clear skin (PASI 90-99) achieved DLQI score of 0, corresponding to the experience of no impairment on QoL (54.4% vs. 37.7%, p = 0.001). Females patients were more likely than males to achieve CSC response (odds ratio [OR] = 1.83; 95% confidence interval [CI]: 1.24-2.70), while previous biologic treatment (OR = 0.43; 95% CI: 0.24-0.81) and joint affected (OR = 0.61; 95% CI: 0.42-0.89) were significantly associated with less CSC response. CONCLUSIONS This study highlights the fact that clinical parameters are important in determining CSC response in psoriasis. In daily practice, achieving CSC represents a clinically meaningful treatment goal, especially from the patient perspective.

Abstract
Endometriosis is defined as the presence of endometrial-like glands and stroma located outside the uterine cavity. This common, estrogen dependent, inflammatory condition affects up to 15% of reproductive-aged women and is a well-recognized cause of chronic pelvic pain and infertility. Despite the still unknown etiology of endometriosis, much evidence suggests the participation of epigenetic mechanisms in the disease etiopathogenesis. The main rationale is based on the fact that heritable phenotype changes that do not involve alterations in the DNA sequence are common triggers for hormonal, immunological, and inflammatory disorders, which play a key role in the formation of endometriotic foci. Epigenetic mechanisms regulating T-cell responses, including DNA methylation and posttranslational histone modifications, deserve attention because tissue-resident T lymphocytes work in concert with organ structural cells to generate appropriate immune responses and are functionally shaped by organ-specific environmental conditions. Thus, a failure to precisely regulate immune cell transcription may result in compromised immunological integrity of the organ with an increased risk of inflammatory disorders. The coexistence of endometriosis and autoimmunity is a well-known occurrence. Recent research results indicate regulatory T-cell (Treg) alterations in endometriosis, and an increased number of highly active Tregs and macrophages have been found in peritoneal fluid from women with endometriosis. Elimination of the regulatory function of T cells and an imbalance between T helper cells of the Th1 and Th2 types have been reported in the endometria of women with endometriosis-associated infertility. This review aims to present the state of the art in recognition epigenetic reprogramming of T cells as the key factor in the pathophysiology of endometriosis in the context of T-cell-related autoimmunity. The new potential therapeutic approaches based on epigenetic modulation and/or adoptive transfer of T cells will also be outlined.

Abstract
Dyslipidemia is a major cause of cardiovascular diseases which represent a leading cause of death in humans. Diverse immune cells are known to be involved in the pathogenesis of cardiovascular diseases such as atherosclerosis. Conversely, dyslipidemia is known to be tightly associated with immune disorders in humans, as evidenced by a higher incidence of atherosclerosis in patients with autoimmune diseases including psoriasis, rheumatoid arthritis, and systemic lupus erythematosus. Given that the dyslipidemia-related autoimmune diseases are caused by autoreactive T cells and B cells, dyslipidemia seems to directly or indirectly regulate the adaptive immunity. Indeed, accumulating evidence has unveiled that proatherogenic factors can impact the differentiation and function of CD4+ T cells, CD8+ T cells, and B cells. This review discusses an updated overview on the regulation of adaptive immunity by dyslipidemia and proposes a potential therapeutic strategy for immune disorders by targeting lipid metabolism.

Abstract
Like other autoimmune diseases, rheumatoid arthritis (RA) develops in distinct stages, with each phase of disease linked to immune cell dysfunction. HLA class II genes confer the strongest genetic risk to develop RA. They encode for molecules essential in the activation and differentiation of T cells, placing T cells upstream in the immunopathology. In Phase 1 of the RA disease process, T cells lose a fundamental function, their ability to be self-tolerant, and provide help for autoantibody-producing B cells. Phase 2 begins many years later, when mis-differentiated T cells gain tissue-invasive effector functions, enter the joint, promote non-resolving inflammation, and give rise to clinically relevant arthritis. In Phase 3 of the RA disease process, abnormal innate immune functions are added to adaptive autoimmunity, converting synovial inflammation into a tissue-destructive process that erodes cartilage and bone. Emerging data have implicated metabolic mis-regulation as a fundamental pathogenic pathway in all phases of RA. Early in their life cycle, RA T cells fail to repair mitochondrial DNA, resulting in a malfunctioning metabolic machinery. Mitochondrial insufficiency is aggravated by the mis-trafficking of the energy sensor AMPK away from the lysosomal surface. The metabolic signature of RA T cells is characterized by the shunting of glucose toward the pentose phosphate pathway and toward biosynthetic activity. During the intermediate and terminal phase of RA-imposed tissue inflammation, tissue-residing macrophages, T cells, B cells and stromal cells are chronically activated and under high metabolic stress, creating a microenvironment poor in oxygen and glucose, but rich in metabolic intermediates, such as lactate. By sensing tissue lactate, synovial T cells lose their mobility and are trapped in the tissue niche. The linkage of defective DNA repair, misbalanced metabolic pathways, autoimmunity, and tissue inflammation in RA encourages metabolic interference as a novel treatment strategy during both the early stages of tolerance breakdown and the late stages of tissue inflammation. Defining and targeting metabolic abnormalities provides a new paradigm to treat, or even prevent, the cellular defects underlying autoimmune disease.

Abstract
Background Psoriasis is a chronic immune-mediated inflammatory skin disease associated with increased development of metabolic abnormalities including obesity and dyslipidemia, as well as increased cardiovascular disease (CVD) risk. Shared pathophysiological mechanisms linking psoriasis to CVD include altered immune activation, elevated chronic systemic inflammation, and lipoprotein dysfunction characterized by oxidative damage to lipids and apolipoproteins. Objective This review aims to provide evidence-based proof for existing relationships between psoriatic inflammation, lipid oxidation, and increased CVD risk. Methods We included review articles and original research papers, published between 1980 and 2020, using the following key words: psoriasis, oxidized lipids, oxidation, dyslipidemia, and inflammation. Results Systemic inflammation underlying psoriasis leads to increased skin accumulation of pro-inflammatory oxidized lipids, derived from the omega-6 fatty acids, along with counteracting anti-inflammatory lipid mediators, products of the omega-3 polyunsaturated fatty acids. Imbalance in these metabolites culminates in impaired inflammation resolution and results in multisystemic biological alterations. Sustained systemic inflammation results in excessive lipid oxidation, generating proatherogenic oxidized low- and high-density lipoproteins. Together, these pathophysiological mechanisms contribute to increased CVD risk associated with psoriasis disease. Conclusion Available anti-inflammatory treatment showed promising clinical results in treating psoriasis, although further research is warranted on managing associated dyslipidemia and establishing novel cardiometabolic markers specific for both skin and vascular pathology.

Abstract
Psoriasis is a systemic inflammatory disorder that involves complex pathogenic interactions between the innate and adaptive immune systems. Individuals with psoriasis have an increased risk of developing other chronic health diseases such cardiovascular disorders. The high incidence of cardiovascular events in the population with psoriasis could be explained by several mechanisms. The high prevalence of traditional cardiovascular risk factors and metabolic abnormalities contributes to the high cardiovascular burden in patients with psoriasis. Likewise, the presence of systemic inflammation in combination with metabolic abnormalities may act in a synergistic manner to increase cardiovascular risk in these patients. This review focused on epidemiologic and clinical evidence linking psoriasis to cardiovascular risk factors and cardiovascular disease. We described the possible pathophysiological mechanisms that justify this association and analyzed the best way to stratify the cardiovascular risk in patients with psoriasis. We also described the usefulness of the therapies frequently used in cardiovascular prevention and analyzed the impact of the specific psoriasis medication on cardiovascular risk factors or major atherosclerotic events. Knowledge of the application of different cardiovascular prevention strategies could mean an advantage in performing the difficult task of estimating cardiovascular risk and treating cardiovascular risk factors in this particular group of patients.

Abstract
The association between psoriasis and cardiovascular disease risk has been supported by recent epidemiological data. Patients with psoriasis have an increased adjusted relative risk for myocardial infarction. As such, the cardiovascular risk conferred by severe psoriasis may be comparable to what is seen with other well-established risk factors, such as diabetes mellitus. Previous studies demonstrated that low-density lipoprotein (LDL) plays critical roles during atherogenesis. It may be caused by the accumulation of macrophages and lipoprotein in the vessel wall. Oxidized LDL (ox-LDL) stimulates the expression of adhesion molecules, such as ICAM-1 and VCAM-1, on endothelial cells and increases the attachment of mononuclear cells and the endothelium. Even though previous evidence demonstrated that psoriasis patients have tortuous and dilated blood vessels in the dermis, which results in the leakage of ox-LDL, the leaked ox-LDL may increase the expression of adhesion molecules and cytokines, and disturb the static balance of osmosis. Therefore, exploration of the relationship between hyperlipidemia and psoriasis may be another novel treatment option for psoriasis and may represent the most promising strategy.

Abstract
INTRODUCTION Statins may reduce the severity of psoriasis, but the available evidence is unclear. We conducted a meta-analysis of randomized controlled studies (RCTs) that investigated the effect of statins on psoriasis severity assessed with the Psoriasis Area and Severity Index (PASI). MATERIAL AND METHODS Two investigators searched independently the following databases: Medline, EMBASE, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov from inception to February 2019. Additionally, reference lists from all available articles were searched manually. We included only RCTs carried out among adult (≥ 16 years) patients with psoriasis who received oral statins for ≥ 8 weeks and had psoriasis severity assessed with the PASI at baseline and at the end of follow-up. We used random effects meta-analysis to calculate the mean difference (D) in PASI change between patients who received either a statin or a comparator. RESULTS Of 279 records identified, there were 5 eligible RCTs, with a total of 223 patients, including 128 patients who received a statin (atorvastatin or simvastatin). The improvement in psoriasis severity (PASI) was significantly greater in patients who received statins than in those who received comparators (D = 2.76, 95% CI: 0.49-5.04, p = 0.017). In subgroup analyses, the improvement in PASI values was significant for simvastatin (D = 3.70, 95% CI: 2.52-4.89, p < 0.001) but not for atorvastatin (D = 2.30, 95% CI: -1.28-5.88, p = 0.210). CONCLUSIONS Oral statins may improve psoriasis, particularly in patients with severe disease. This observation should be verified in long-term, well-designed studies that will enable analyses adjusted for clinical variables.

Abstract
The incidence of atherosclerosis is higher among patients with several autoimmune diseases such as psoriasis, rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). It is well documented that innate immune cells including macrophages and dendritic cells sense lipid species such as saturated fatty acids and oxidized low-density lipoprotein and produce pro-inflammatory cytokines and chemokines. However, whether a hyperlipidemic environment also impacts autoimmune T cell responses has been unclear. Among CD4+ T cells, Th17 and follicular helper T (Tfh) cells are known to play pathogenic roles in the development of hyperlipidemiaassociated autoimmune diseases. This review gives an overview of the cellular and molecular mechanisms by which dysregulated lipid metabolism impacts the pathogenesis of autoimmune diseases, with specific emphasis on Th17 and Tfh cells.

Abstract
BACKGROUND Psoriasis, the prevalence of which ranges from 2% to 3% of the general population, has been recently recognised as not only a chronic inflammatory skin disorder but also an immunometabolic systemic disease. Dyslipidemia is one of the most important comorbidities of psoriasis. Statins, frequently used as anti-hyperlipidemic agents, may be beneficial in the treatment of several autoimmune diseases, including psoriasis, due to their anti-inflammatory and immunomodulatory characteristics. Hence, we hypothesised that using this medication was not only beneficial for reducing hyperlipidemia but also improving psoriatic conditions. AIM We conducted a study to determine the prevalence of dyslipidemia in psoriatic patients as well as whether the addition of statins (simvastatin prescribed forms) to standard topical antipsoriatic treatment can improve skin lesions in psoriatic patients. METHODS A group of 128 psoriatic patients and 128 healthy controls who were matched with the patients regarding ethnicity, age, and sex were enrolled, and their lipid concentrations were determined. Furthermore, sixty patients were randomly selected from the former group and divided into two treatment subgroups to evaluate the effect of statins on the severity of psoriasis using the PASI score. RESULTS We found that the rate of dyslipidemia in the patient group was significantly higher than in the healthy group (53.9% versus 21.9%, p < 0.001), particularly the triglyceride concentration (1.86 ± 1.17 versus 1.43 ± 0.79 mg/dL, p < 0.001). Also, the PASI score reduction in the simvastatin-treated subgroup was significantly different from that in the placebo-treated one after eight weeks of therapy (8.63 ± 4.78 versus 5.34 ± 3.59, p < 0.01). CONCLUSION This study showed that simvastatin might play a role in controlling hyperlipidemia and in turn decrease the PASI score in psoriatic patients.

Abstract
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.

OBJECTIVES To evaluate the effect of Atorvastatin as an adjuvant with betamethasone valerate on disease severity and cardiovascular risks in chronic plaque type psoriatic patients. METHODS It is an interventional study conducted in Pharmacology Department of BMSI, JPMC with the collaboration of Dermatology Department of JPMC, Karachi. The duration of study was from June 2013 to June 2016. Seventy five psoriatic patients were prescribed Tablet Atorvastatin 40-20 mg/day (40mg for first three months twice daily followed by 20mg once daily for the next three month) plus topical Betamethasone Valerate 0.1% once daily for 6 months (three week apply than one week interval). The efficacy and safety profile of drugs was measured by PASI, DLQI, hsCRP, LFTS and Lipid profile. RESULTS The percentage change of PASI is 86.749±0.547, DLQI is 82.697±.2.61 and hsCRP is 40.371±8.505, which showed highly significant improvement in patient at the end of last follow up. LFTs and CPK for safety profile of therapy showed non-significant results. CONCLUSION Atorvastatin used as an adjuvant therapy with currently existing standard therapy (topical betamethasone) in patients having mild to moderate plaque type psoriasis reduces disease severity and cardiovascular risks.

Abstract
Psoriasis is a potentially debilitating inflammatory dermatosis affecting 0.2%-4.8% of the population worldwide causing a significant occupational, personal or psychosocial morbidity to these patients for life. The basic aim of psoriasis therapy is to control the disease to maximum possible extent and improve the patient’s quality of life. Management of triggers for flare-ups, lifestyle modifications, and dietary supplements are often recommended. Intermittent or rotational therapy with frequent alterations in treatment options is usually needed to reduce toxicity of anti-psoriatic drugs in the absence of safer alternatives. Currently, several biological agents categorized as either T-cell targeted (e.g., Alefacept, Efalizumab) or cytokine modulating (e.g., Adalimumab, Infliximab, Etanercept) are available for treating severe psoriasis. However, their high cost is often precluding for most patients. The usefulness of systemic (methotrexate, cyclosporine, acitretin or several other therapeutic agents) or topical (tar, anthralin, corticosteroids or calcipotriol ointments, phototherapy with or without psoralens) therapies has been well established for the management of psoriasis. The literature is also replete with benefits of less used non-standard and unconventional treatment modalities (hydroxycarbamide, azathioprine, leflunomide, mycophenolate mofetil, isotretinoin, fumarates, topical calcineurin inhibitors, peroxisome proliferator-activated receptors agonists, statins, sulfasalazine, pentoxifylline, colchicine, grenz ray therapy, excimer laser, climatotherapy and balneophototherapy, peritoneal dialysis, tonsillectomy, ichthyotherapy, etc.). These can be used alternatively to treat psoriasis patients who have mild/minimal lesions, are intolerant to conventional drugs, have developed side effects or achieved recommended cumulative dose, where comorbidities pose unusual therapeutic challenges, or may be as intermittent, rotational or combination treatment alternatives.

Abstract
BACKGROUND Statins have been shown to downregulate immune mechanisms activated in psoriasis. However, previous studies on their potential role in preventing psoriasis have yielded conflicting results. OBJECTIVES To assess the relationship between adherence to statins and the risk of psoriasis. METHODS This retrospective cohort study included 205,820 health plan enrollees in Israel (mean age 55 years; 54·1% women) who initiated statin treatment from January 1998 through to September 2009. Adherence to statins, measured by the proportion of days covered (PDC), throughout the entire follow-up period (mean 6·2 years) was recorded. Diagnosis codes of psoriasis were assigned by a dermatologist or rheumatologist, or at discharge from hospital. RESULTS During 1·28 million person-years (PY) of follow-up (median 5·74 years per person; interquartile range 3·78-8·36), 5615 cases of psoriasis (incidence density rate 4·4 per 1000 PY) were recorded. Compared with patients who did not adhere to statins (PDC < 20%), patients covered by statins for 40-59% of the time had a significantly lower risk of psoriasis (P < 0·05), with hazard ratios (HRs) of 0·84 and 0·74 among men and women, respectively. Among patients who adhered better to statins (PDC ≥ 80%), HRs were 0·88 (95% CI 0·79-0·98) and 1·00 (95% CI 0·90-1·11) among men and women, respectively. CONCLUSIONS The results of the current study suggest that high and long-term adherence to statins is not associated with a meaningful reduction in the risk of developing psoriasis.

Abstract
OBJECTIVES The chronic periodontitis (CP) and psoriasis share common risk factors and co-morbidities. This study was designed to explore how frequently CP is associated with patients with psoriasis compared to systemic healthy subjects. MATERIALS AND METHODS The periodontal clinical parameters probing depth (PD), periodontal attachment level (PAL), and presence or absence of radiographic bone loss (J Periodontol, 78, 2007, 1387) were recorded in 33 psoriasis subjects and 35 healthy subjects. The severity of psoriasis was assessed and recorded by Psoriasis Area and Severity Index as described earlier by Cohen et al (J Dermatolog Treat, 16, 2005, 308). The other oral health characteristics were also recorded. RESULTS Probing depth and PAL showed significant higher values in psoriasis group compared with healthy group. It was also found that periodontal status was associated with severity of psoriasis. CONCLUSIONS The results showed a link between CP and psoriasis. This suggests the need for a multidisciplinary approach to manage psoriasis patients with chronic periodontitis, especially in relation to current and future treatment.

Abstract
Aim: The present research work was aimed to formulate and characterize psoralen-encapsulated cavamax W7 composite ethosomal gel and compare its in vitro and ex vivo behavior against psoralen-cavamax W7-complex reference gel. Materials and Methods: A total of nine formulations of composite ethosomes were prepared by injection method using 32 factorial design and entrapment efficiency was designated as dependent variable. Concomitantly, psoralen was complexed with cavamax W7 (1:1 molar ratio) by kneading method and formation of complex was confirmed by Diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), X-ray diffraction (XRD), and differential scanning calorimetry (DSC). Results: F9 with vesicle size of 183 ± 2.8 nm, and highest % entrapment efficiency of 98.12 ± 1.15 was selected as optimized formulation. Transmission electron microscopy (TEM) revealed uniform and spherical shaped vesicles. The optimized formulation F9 was formulated as carbapol gel and compared against ethosomal gel, psoralen gel, and psoralen cavamax W7 complex gel. The gels were evaluated for permeation characteristics and the rank order was composite ethosomal gel > ethosomal gel > psoralen-cavamax W7 complex gel > psoralen gel. The ethosomal gel (G5) with highest in vitro permeation of 82.48 ± 2.23% was subjected to in vivo Confocal laser scanning microscopy (CLSM) studies using rhodamine B as tracer. The penetration of rhodamine B was uniform, deeper, and two times faster into epidermis than control gel. Conclusion: Conclusively, cavamax W7 composite ethosomes present themselves as efficient carrier for superior topical delivery of psoralen and have potential for clinical applications in minimizing side effects associated with photosensitivity of psoralen.

Abstract
Cell signaling for T-cell growth, differentiation, and apoptosis is initiated in the cholesterol-rich microdomains of the plasma membrane known as lipid rafts. Herein, we investigated whether enrichment of membrane cholesterol in lipid rafts affects antigen-specific CD4 T-helper cell functions. Enrichment of membrane cholesterol by 40–50% following squalene administration in mice was paralleled by an increased number of resting CD4 T helper cells in periphery. We also observed sensitization of the Th1 differentiation machinery through co-localization of IL-2Rα, IL-4Rα, and IL-12Rβ2 subunits with GM1 positive lipid rafts, and increased STAT-4 and STAT-5 phosphorylation following membrane cholesterol enrichment. Antigen stimulation or CD3/CD28 polyclonal stimulation of membrane cholesterol-enriched, resting CD4 T-cells followed a path of Th1 differentiation, which was more vigorous in the presence of increased IL-12 secretion by APCs enriched in membrane cholesterol. Enrichment of membrane cholesterol in antigen-specific, autoimmune Th1 cells fostered their organ-specific reactivity, as confirmed in an autoimmune mouse model for diabetes. However, membrane cholesterol enrichment in CD4+Foxp3+ T-reg cells did not alter their suppressogenic function. These findings revealed a differential regulatory effect of membrane cholesterol on the function of CD4 T-cell subsets. This first suggests that membrane cholesterol could be a new therapeutic target to modulate the immune functions, and second that increased membrane cholesterol in various physiopathological conditions may bias the immune system toward an inflammatory Th1 type response.

Abstract
STUDY OBJECTIVE To explore the efficacy and safety of oral atorvastatin for the treatment of plaque-type psoriasis. DESIGN Prospective, randomized, double-blind, placebo-controlled study. SETTING University-affiliated psoriasis outpatient clinic in Iran. PATIENTS Forty-two patients aged 16-60 years with a diagnosis of acute or chronic plaque-type psoriasis with body surface area (BSA) involvement of greater than 10% were enrolled; 40 completed the study. Intervention. Oral atorvastatin 40 mg/day (20 patients) or placebo (20 patients) was administered for 12 weeks; patients' topical therapies with emollients, keratolytics, and/or class V corticosteroids were continued during the study period. MEASUREMENTS AND MAIN RESULTS The Psoriasis Area and Severity Index (PASI) and percentage BSA involvement were used to assess the efficacy of therapy. Mean ± SD baseline PASI scores were 7.42 ± 1.90 and 6.92 ± 1.76 in the atorvastatin and placebo groups, respectively. The primary outcomes were the degree of change in PASI scores and percentage BSA involvement from baseline to week 12. Significant improvement in psoriasis lesions was observed in both the atorvastatin and placebo groups (p<0.001 for both groups). A 75% improvement in PASI score (PASI 75) was achieved in 8 patients (40%) in the atorvastatin group and 7 patients (35%) in the placebo group. However, no statistically significant differences were noted between the two treatment groups in mean PASI score, percentage BSA involvement, and PASI 75. In terms of adverse effects, atorvastatin was well tolerated. CONCLUSION Oral atorvastatin 40 mg/day was not associated with therapeutic benefit when given to patients with baseline PASI scores less than 12 who were also treated with standard topical therapies. Additional trials are needed to elucidate the place of statins for the treatment of psoriasis. A larger follow-up study, as well as testing atorvastatin in patients with more intensive disease characterized by high PASI scores, is needed. Studies using higher atorvastatin doses or dose-ranging studies should also be performed.
