Abstract
Dietary habits strongly influence our health status, mostly in terms of maintenance of the inflammatory/anti-inflammatory homeostasis. High fat and high sugar diets account for the development of a low-grade inflammation, which is the pathogenic common denominator of various chronic diseases. Severe Acute Respiratory Syndrome Coronavirus (SARS)-CoV2 (COVID-19) infection affects all ages and especially frail elderly people and a nutritional intervention seems to be crucial in the course of this pandemic. The present review describes the properties of some vegetal products and their derivatives, such as Lupin sp., garlic, salvia and extra virgin olive oil (EVOO) that can be exploited for their beneficial effects, as preventive and/or nutritional treatment of coronavirus disease SARS-CoV2. Lupin, salvia, garlic and EVOO share overlapping properties, such as anti-oxidant, anti-inflammatory and anti-viral activities. Quite importantly, these products and their derivatives are able to recover the expression of angiotensin converting enzyme expression 2 on cell membrane, otherwise suppressed by COVID-19 binding and entry into cytoplasm. Dietary administration of the above nutraceuticals or their extracts may play a preventive or nutritional role in the course of SARS-CoV2 infection, even including the effects of the lockdown and the condition of inflamm-ageing.

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.

Abstract
Metabolic syndrome is a common metabolic disorder which has become a public health challenge worldwide. There has been growing interest in medications including natural products as complementary or alternative choices for common chemical therapeutics regarding their limited side effects and ease of access. Nanosizing these compounds may help to increase their solubility, bioavailability, and promisingly enhance their efficacy. This study, for the first time, provides a comprehensive overview of the application of natural-products-based nanoformulations in the management of metabolic syndrome. Different phytochemicals including curcumin, berberine, Capsicum oleoresin, naringenin, emodin, gymnemic acid, resveratrol, quercetin, scutellarin, stevioside, silybin, baicalin, and others have been nanosized hitherto, and their nanosizing method and effect in treatment and alleviating metabolic syndrome have been reviewed and discussed in this study. It has been discovered that there are several pathways or molecular targets relevant to metabolic disorders which are affected by these compounds. Various natural-based nanoformulations have shown promising effect in treatment of metabolic syndrome, and therefore can be considered as future candidates instead of or in conjunction with pharmaceutical drugs if they pass clinical trials successfully.

Plant α-amylase inhibitors and their effect on the utilization of polysaccharides contained in the diet.
Kurhajec, S, Franc, A
Ceska a Slovenska farmacie : casopis Ceske farmaceuticke spolecnosti a Slovenske farmaceuticke spolecnosti. 2019;(4):148-156
Abstract
Development of civilization diseases such as diabetes mellitus, metabolic syndrome or obesity, enforces the increasing effort to find new drugs, especially from natural sources. These include α-amylase inhibitors, which break down polysacharides into simple sugars in the body of a healthy person. As this cleavage affects the level of blood sugar, which is sought to be therapeutically influenced, there is a growing interest in these substances. This review maps the types of amylase inhibitors, including their natural resources.

Abstract
OBJECTIVE Second-generation antipsychotics (SGAs) have a negative impact on metabolic syndrome (MetS) risk factors for their effects on body weight and on metabolic parameters. Statins are widely used in the treatment of dyslipidemia; less is known on the ability of statins to treat SGAs-induced dyslipidemia, and nutraceutical approaches may represent promising strategies in SGAs-treated patients. Red Yeast Rice (RYR), the fermented product of the Aspergillaceae mold Monascus purpureus (red yeast) grown on white rice, has been shown to have a cholesterol-lowering effect which can be ascribed to monacolin K, although other active compounds may play a role management of hyperlipidemia. The present study was aimed to explore the efficacy and safety of RYR treatment on clinical and metabolic parameters in a sample of subjects receiving SGAs. METHODS Fifteen outpatients treated with SGAs assumed RYR at the oral daily dose of 200 mg/day (total monacolin K = 11.88 mg) for 30 days. Fasting levels of triglycerides, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and glucose were determined. RESULTS RYR administration resulted in a statistically significant reduction of LDL (p = 0.029), corresponding to 11.0% decrease from baseline mean value. No significant differences in clinical and in other and metabolic parameters were observed. CONCLUSIONS Our findings suggest that RYR, at the daily dose of 200 mg for 30 days, could be a promising agent to prevent and/or treat SGAs-induced hyperlipidemia. However, future adequately-powered and well-designed studies with long-term follow-up should evaluate RYR effectiveness, as an alternative option to statins, on the SGAs-induced metabolic side effects.

Abstract
Natural antioxidants present in fruits have attracted considerable interest due to their presumed safety and potential nutritional value. Even though antioxidant activities of many fruits have been reported, the effects of phytochemicals of goji berry (GB) in patients with metabolic syndrome have not been investigated. In this study, we examined anthropometric and biochemical parameters in patients with metabolic syndrome after the consumption of GB. The patients were divided into two groups, control (C) and supplemented (S), and followed up for 45 days. Participants were individually instructed to carry out a healthy diet, but additionally, an inclusion of 14 g of the natural form of goji berry in the diet during 45 days for the S group was proposed. After 45 days of study, a significant reduction in transaminases as well as an improvement in lipid profile in the S group was observed. Likewise, a significant reduction in the waist circumference of the S group was observed when compared with that of the C group, and increased glutathione and catalase levels associated with a reduction of lipid peroxidation. These results suggest that this is an effective dietary supplement for the prevention of cardiovascular diseases in individuals with metabolic syndrome.

Jiménez-Osorio, AS, González-Reyes, S, Pedraza-Chaverri, J
Clinica chimica acta; international journal of clinical chemistry. 2015;:182-92
Abstract
Prediabetes and diabetes are rising worldwide. Control of blood glucose is crucial to prevent or delay diabetic complications that frequently result in increased morbidity and mortality. Most strategies include medical treatment and changes in lifestyle and diet. Some nutraceutical compounds have been recognized as adjuvants in diabetes control. Many of them can activate the nuclear factor (erythroid-derived 2)-like 2 (Nrf2), which has been recognized as a master regulator of the antioxidant response. Recent studies have described the role of Nrf2 in obesity, metabolic syndrome, nephropathy, retinopathy and neuropathy, where its activation prevents the development of diabetes and its complications. It has been demonstrated that natural compounds derived from plants, vegetables, fungi and micronutrients (such as curcumin, sulforaphane, resveratrol and vitamin D among others) can activate Nrf2 and, thus, promote antioxidant pathways to mitigate oxidative stress and hyperglycemic damage. The role of some natural Nrf2 activators and its effect in diabetes is discussed.

[Psoriasis].
Navarini, AA, Trüeb, RM
Therapeutische Umschau. Revue therapeutique. 2010;(4):153-65
Abstract
Psoriasis is a skin disease typically presenting with sharply demarcated, inflammatory, erythematous plaques with characteristic silver-white scaling due to epidermal hyperproliferation and parakeratosis secondary to the inflammation. The name derives from pisigmaomicronrhoalpha (mange or scabies), and in ancient times the disease was confused with leprosy resulting in expulsion from society. Hence, both itching and social stigmatization are major problems affecting patients with psoriasis. Today, psoriasis is recognized as a genetically determined, autoimmune, T cell mediated systemic disease manifesting on the skin, nails and joints and associated with a number of co-morbidities. Accordingly, therapeutic strategies are antiinflammatory, antiproliferative and keratolytic. The extent and severity of disease (PASI), impairment of life quality (DLQI), and affected anatomic regions (inverse, palmoplantar, nails) as well as co-morbidities (arthritis, metabolic syndrome, cardiovascular disease, depression) determine the therapy. In 80 % of cases psoriasis is mild or moderate and sufficiently treated with topical corticosteroids, vitamin D-analogues, and phototherapy. 20 % of patients suffer from severe psoriasis, necessitating systemic drugs such as acitretin, methotrexate, ciclosporin A or the newer biologic agents. Especially in severe psoriasis, psychological strain, co-morbidities, and medico-economic aspects must be taken into account.
