Abstract
IMPORTANCE The PCSK9 inhibitor evolocumab reduced low-density lipoprotein cholesterol and cardiovascular events in the FOURIER randomized clinical trial. Patients with metabolic syndrome (MetS) are at increased cardiovascular risk. OBJECTIVE To investigate outcomes with evolocumab in patients with and without MetS. DESIGN, SETTING, AND PARTICIPANTS The FOURIER trial randomized patients worldwide with stable atherosclerotic cardiovascular disease receiving statin to evolocumab vs placebo with follow-up for a median of 2.2 years. Data were collected February 2013 to November 2016. For this prespecified analysis, patients with the requisite data were stratified based on the National Cholesterol Education Program Adult Treatment Panel III MetS criteria; in secondary analyses, patients were further substratified by diabetes at baseline. Analysis was intention to treat. Analysis began March 2018 and ended April 2020. INTERVENTIONS Patients were randomized to evolocumab or placebo. MAIN OUTCOMES AND MEASURES The primary end point was cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization. The key secondary end point was cardiovascular death, myocardial infarction, or stroke. RESULTS Of 27 342 patients (mean [SD] age, 63 [9] years; 20 623 men [75.4%]) included in this analysis, 16 361 (59.8%) with baseline MetS were, when compared with patients without MetS, at higher risk of cardiovascular events (adjusted hazard ratio [95% CI], 1.31 [1.18-1.46]; P < .001 for the primary and 1.38 [1.20-1.57]; P < .001 for the key secondary end point). Evolocumab reduced low-density lipoprotein cholesterol similarly in patients with MetS (median [interquartile range], 92 [79-109] mg/dL vs 30 [19-48] mg/dL; P < .001) and without MetS (median [interquartile range], 92 [81-108] mg/dL vs 29 [18-44] mg/dl; P < .001). For the primary end point, the hazard ratios (95% CI) with evolocumab vs placebo were 0.83 (0.76-0.91) and 0.89 (0.79-1.01) in patients with and without MetS (P for interaction = .39). For the key secondary end point, the corresponding hazard ratios (95% CIs) were 0.76 (0.68-0.86) and 0.86 (0.74-1.01) (P for interaction = .23), respectively. Evolocumab did not increase the risk of new-onset diabetes or other major safety outcomes including worsening glycemic control, compared with placebo in patients with MetS. CONCLUSIONS AND RELEVANCE Patients with atherosclerotic cardiovascular disease and MetS have substantial residual risk of cardiovascular events despite statin therapy. Evolocumab significantly reduced low-density lipoprotein cholesterol and cardiovascular risk in patients with MetS without increasing new-onset diabetes, worsening glycemic control, or other major safety events. These data suggest the addition of evolocumab to statin therapy in patients with atherosclerotic cardiovascular disease and MetS is safe and efficacious to reduce residual cardiovascular risk.

Abstract
Inflammatory diseases including psoriasis are associated with metabolic and cardiovascular comorbidities, including obesity and metabolic syndrome. Obesity is associated with greater psoriasis disease severity and reduced response to treatment. Therefore, targeting metabolic comorbidities could improve patients' health status and psoriasis-specific outcomes. METABOLyx is a randomized controlled trial evaluating the combination of a lifestyle intervention program with secukinumab treatment in psoriasis. Here, the rationale, methodology and baseline patient characteristics of METABOLyx are presented. A total of 768 patients with concomitant moderate to severe plaque psoriasis and metabolic syndrome were randomized to secukinumab 300 mg, or secukinumab 300 mg plus a tailored lifestyle intervention program, over 24 weeks. A substudy of immunologic and metabolic biomarkers is ongoing. The primary endpoint of METABOLyx is PASI90 response at week 24. Other endpoints include patient-reported outcomes and safety. METABOLyx represents the first large scale clinical trial of an immunomodulatory biologic in combination with a standardized lifestyle intervention.

Dermatologic therapy. 2020;(6):e14281
Abstract
The safety of methotrexate in psoriasis patients with metabolic syndrome could be argued because of increased risk of liver toxicity. The aim of the study was to investigate the safety of methotrexate compared with secukinumab in psoriasis patients with metabolic syndrome. A controlled, open trial in psoriasis patients with metabolic syndrome, candidate to methotrexate, or secukinumab. Primary end point of the study was investigating any variations in waist circumference, body mass index, blood pressure, fasting glucose, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, triglycerides, aspartate aminotransferase, alanine aminotransferase, creatinine levels between baseline and month-6 and 12 of follow-up in the two treatment cohorts. A total of 130 (110 male and 20 female) patients were consecutively assigned in a 1:1 ratio to treatment with methotrexate (n = 64) dosed 15 mg weekly or secukinumab (n = 66) at standard dose. At month-6 and month-12 serum levels of liver enzymes were significantly increased only in patients treated with methotrexate (P < .01). Three times elevation of liver enzymes was reported in 4 of 64 patients receiving methotrexate, causing drug withdrawal. No significant changes in other parameters were observed. Methotrexate could induce a liver enzyme increase whereas secukinumab has a neutral effect.

Abstract
Background: Metabolic syndrome (MetS) is the most prevalent comorbidity in psoriasis and increases the risk of cardiovascular disease, diabetes, and mortality. Assessment of impacts of biologic therapies on cardiometabolic risk factors are relatively limited. This study evaluated the effect of tildrakizumab on cardiometabolic risk factors in patients with moderate to severe plaque psoriasis and stratified by MetS status. Methods: In this post hoc analysis of reSURFACE 1/2, tildrakizumab 100 and 200 mg were continuously administered to patients with moderate to severe plaque psoriasis at weeks 0 and 4, and every 12 weeks thereafter. Mean and mean percent changes from baseline were assessed for fasting serum glucose, low/high-density lipoprotein-cholesterol, total cholesterol, triglyceride levels, body weight, and blood pressure at week 64/52 for reSURFACE 1 and 2, respectively, in patients with and without MetS. Results: A total of 369 patients in reSURFACE 1 and 2 received continuous tildrakizumab 100 mg and 330 received tildrakizumab 200 mg; 21.4% and 20.3% in reSURFACE 1 and 2, respectively, had MetS. At week 64/52, mean changes in cardiometabolic risk factors from baseline did not significantly differ regardless of MetS status. Numerically larger mean decreases in fasting glucose, triglycerides, and systolic blood pressure following tildrakizumab 100 mg and in systolic and diastolic blood pressure following tildrakizumab 200 mg were observed in patients with MetS relative to those without MetS. Conclusions: Changes in cardiometabolic disease risk factors following tildrakizumab treatment were limited. Risk factors were not increased in patients with MetS vs without MetS.

Abstract
Even though it is only a little over a decade from the discovery of proprotein convertase subtilisin/kexin type 9 (PCSK9) as a plasma protein that associates with both hypercholesterolemia and low cholesterol syndromes, a rich literature has developed describing its unique physiology and the impact of antagonism of this molecule on cholesterol metabolism for therapeutic purposes. Indeed, the PCSK9 story is unfolding rapidly, with many answers and more questions. This review summarizes the most recent data from phase II/III clinical trials of PCSK9 inhibition with the three leading antibodies, highlights the clinical significance of the ongoing studies, and suggests future areas of investigation based on recent basic science discoveries on the physiology of PCSK9.

[The clinical significance of hepcidin detection in the patients with anemia and rheumatoid arthritis].
Galushko, EA
Klinicheskaia meditsina. 2014;(6):21-7
Abstract
The prevalence of anemia in patients with rheumatoid arthritis (RA) varies from 30 to 70%. 25% of the cases are diagnosed within 1 year after onset of the disease. On the whole, anemia in RA is described as anemia of a chronic disease (ACD). Pathogenesis ofACD is a multifactor process underlain by an immune mechanism: cytokines and cells ofthe reticuloendothelial system cause changes in iron homeostasis, proliferation of erythroid precursors, erythropoietin production and lifespan of erythrocytes. The key pathogenetic factor is disordered iron metabolism. IL-6 increasing hepatic production acute-phase protein (hepcidin) is the most important cytokine involved in ACD pathogenesis. Hence the necessity to measure its serum level for differential diagnostics of anemic syndrome in patients with RA and the choice of effective basal therapy. Recent data on the therapeutic potency of tocilizumab (IL-6 receptor inhibitor) demonstrate not its safety and sustainable beneficial clinical effect in combination with the favourable action on hemoglobin profile and reduction offatigue.
