Clinical Approach in the Management of Paediatric Patients with Familial Hypercholesterolemia: A National Survey Conducted by the LIPIGEN Paediatric Group.

Detection and treatment of patients with familial hypercholesterolemia (FH) starting from childhood is fundamental to reduce morbidity and mortality. The activity of National realities such as the LIPIGEN (LIpid transPort disorders Italian GEnetic Network) Paediatric Group, founded in 2018, is a milestone in this context. The aim of this exploratory survey, conducted in October 2021 among Italian lipid clinics included in the LIPIGEN Paediatric Group, was to investigate the current clinical approach in the management and treatment of paediatric patients with suspected FH.

Peripheral blood mononuclear cells reactivity in recent-onset type I diabetes patients is directed against the leader peptide of preproinsulin, GAD65 and GAD65.

Introduction: T cell reactivity against pancreatic autoantigens is considered one of the main contributors to the destruction of insulin-producing cells in type 1 diabetes (T1D). Over the years, peptide epitopes derived from these autoantigens have been described in NOD mice and in both HLA class II transgenic mice and humans. However, which ones are involved in the early onset or in the progressive phases of the disease is still unclear.

Metabolomics analysis of plasma samples of patients with fibromyalgia and electromagnetic sensitivity using GC-MS technique.

Fibromyalgia (FM) is a chronic and systemic condition that causes widespread chronic pain, asthenia, and muscle stiffness, as well as in some cases depression, anxiety, and disorders of the autonomic system. The exact causes that lead to the development of FM are still unknown today. In a percentage of individuals, the symptoms of FM are often triggered and/or exacerbated by proximity to electrical and electromagnetic devices.

The impact of the secondary infections in ICU patients affected by COVID-19 during three different phases of the SARS-CoV-2 pandemic.

Microbial secondary infections can contribute to an increase in the risk of mortality in COVID-19 patients, particularly in case of severe diseases. In this study, we collected and evaluated the clinical, laboratory and microbiological data of COVID-19 critical ill patients requiring intensive care (ICU) to evaluate the significance and the prognostic value of these parameters. One hundred seventy-eight ICU patients with severe COVID-19, hospitalized at the S.

Toward the renal vesicle: Ultrastructural investigation of the cap mesenchyme splitting process in the developing kidney.

Background: A complex sequence of morphogenetic events leads to the development of the adult mouse kidney. In the present study, we investigated the morphological events that characterize the early stages of the mesenchymal-to-epithelial transition of cap mesenchymal cells, analyzing in depth the relationship between cap mesenchymal induction and ureteric bud (UB) branching.

Design And Methods: Normal kidneys of newborn non-obese diabetic (NOD) mice were excised and prepared for light and electron microscopic examination.

Contribution of Metabolomics to the Understanding of NAFLD and NASH Syndromes: A Systematic Review.

Several differential panels of metabolites have been associated with the presence of metabolic syndrome and its related conditions, namely non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). This study aimed to perform a systematic review to summarize the most recent finding in terms of circulating biomarkers following NAFLD/NASH syndromes. Hence, the research was focused on NAFLD/NASH studies analysed by metabolomics approaches.

Metabolomics and psychological features in fibromyalgia and electromagnetic sensitivity.

Fibromyalgia (FM) as Fibromyalgia and Electromagnetic Sensitivity (IEI-EMF) are a chronic and systemic syndrome. The main symptom is represented by strong and widespread pain in the musculoskeletal system. The exact causes that lead to the development of FM and IEI-EMF are still unknown.

Autosomal Recessive Hypercholesterolemia: Long-Term Cardiovascular Outcomes.

Background: Autosomal recessive hypercholesterolemia (ARH) is a rare lipid disorder characterized by premature atherosclerotic cardiovascular disease (ASCVD). There are sparse data for clinical management and cardiovascular outcomes in ARH.

Objectives: Evaluation of changes in lipid management, achievement of low-density lipoprotein cholesterol (LDL-C) goals and cardiovascular outcomes in ARH.

Pharmacological treatment of a Sardinian patient affected by Autosomal Recessive Hypercholesterolemia (ARH).

Background And Aim: Previous studies have shown that patients with autosomal recessive hypercholesterolemia (ARH) resulting from mutations in LDLRAP1 gene have a less severe cardiovascular involvement than familial hypercholesterolemia homozygotes, lower levels of low-density lipoprotein cholesterol (LDL-C), and higher levels of high-density lipoprotein cholesterol (HDL-C). In addition, ARH patients seem to be more responsive to the lipid-lowering drugs. The aim was to test the effect of a combined drug treatment in an ARH patient in the absence of plasmapheresis.

The pine-cone body: an intermediate structure between the cap mesenchyme and the renal vesicle in the developing nod mouse kidney revealed by an ultrastructural study.

Nephrogenesis is mainly characterized by the interaction of two distinct renal constituents, the ureteric bud and the metanephric mesenchyme. In this paper we describe by means of light and electron microscopic techniques the morphological events that take place during the early stages of cap mesenchymal formation. Samples of normal renal tissue were excised from newborn NOD mice and processed by standard light and electron microscopy techniques.

High meat consumption is associated with type 1 diabetes mellitus in a Sardinian case-control study.

The large worldwide variation in type 1 diabetes incidence and increasing incidence over time points toward important environmental risk factors. Among them, nutrition plays an important role. The objective was to investigate the relationship between type 1 diabetes and nutritional factors in pregnancy and early in life.

Insulin resistance: pathophysiology and rationale for treatment.

After binding to its receptor and activating the β-subunit, insulin is faced with two divergent pathways: one is phosphatidylinositol 3-kinase (PI 3-K) dependent, while another is dependent upon activation of mitogen-activated protein kinase (MAP-K). The former is absolutely necessary for mediating most metabolic and antiapoptotic effects; the latter is linked to nonmetabolic, proliferative and mitogenic effects. In obese patients, especially with type 2 diabetes mellitus (DM2), only the PI 3-K, but not the MAP-K, is resistant to insulin stimulation: hence insulin resistance is better defined as metabolic insulin resistance.

Colchicine reduces procollagen III and increases pseudocholinesterase in chronic liver disease.

Aim: To test whether colchicine would be an effective antifibrotic agent for treatment of chronic liver diseases in patients who could not be treated with alpha-interferon.

Methods: Seventy-four patients (46 males, 28 females) aged 40-66 years (mean 53 +/- 13 years) participated in the study. The patients were affected by chronic liver diseases with cirrhosis which was proven histologically (n = 58); by chronic active hepatitis C (n = 4), chronic active hepatitis B (n = 2), and chronic persistent hepatitis C (n = 6).

Risk factors for cardiovascular disease in Sardinia from 1978 to 2001: a comparative study with Italian mainland.

Background: This study is a survey of cardiovascular risk factors in Sardinia in the years 1999-2001 and allows us to update previously observed trends of such factors and to compare them with those in the Italian mainland.

Methods: Random samples of free living population of the Mediterranean island of Sardinia, Italy, were collected. Overall, 6818 subjects, 50% of each sex, and aged 20-80+ years constituted the sample.

Incidence of diabetes mellitus among children of Italian migrants substantiates the role of genetic factors in the pathogenesis of type 1 diabetes.

Unlabelled: To investigate the role of genetic and environmental factors in the pathogenesis of type 1 diabetes mellitus (T1D), we carried out a study in Germany aimed at comparing the prevalence and incidence of T1D among children of migrant Italians from high-risk (Sardinia) and low-risk (continental Italy) regions versus German children. Children from Italy were identified by the "Baden-Wuerttemberg (BW) Diabetes Incidence Registry", which registered 4017 newly diagnosed T1D patients, aged 0-14 years, between 1987 and 2003. Data relating to T1D children from Sardinia were elicited from more than 2000 questionnaires.

Effects of chronic hyperinsulinemia in insulin-resistant patients.

Selective insulin resistance influences pathogenesis and treatment of type 2 diabetes and metabolic syndrome. Downregulation of the antiatherogenic pathway and maintained activity of the proatherogenic and cancerogenic pathways lead to atherosclerosis and cancer. Exogenous insulin added to "compensatory" hyperinsulinemia might worsen the primary end points, resulting in potential increase in cardiovascular and cancer events in spite of improvement of surrogate metabolic end points.

Gene-nutrient interactions in G6PD-deficient subjects--implications for cardiovascular disease susceptibility.

Background/aims: The enzyme glucose-6-phosphate dehydrogenase (G6PD) is the principal source of reducing equivalents, necessary for regenerating reduced glutathione through NADPH in order to protect cells from oxidative damage, and whichin erythrocytes produces hemolysis. When fava beans are ingested by G6PD-deficient subjects (gene-nutrient interaction), or some oxidant drugs are assumed (gene-drug interactions), a life-threatening hemolysis can occur. However, the same defect results in lower cardiovascular disease (CVD) risk.

The thyroid hormone receptor-beta agonist GC-1 induces cell proliferation in rat liver and pancreas.

Thyroid hormones regulate cell growth, cell differentiation, and metabolic functions via interaction with the thyroid hormone nuclear receptors (TRs). Recently, a small class of halogen-free high-affinity thyroid hormone agonists has been developed that are highly selective for the TRbeta subtype. Because of the selective hyperthyroidism generated by one of these agonists, GC-1, this compound has the potential to be developed as a new therapeutic agent for the treatment of a variety of metabolic disturbances, including lipid disorders and obesity; thus, it becomes important to determine whether GC-1 has other unknown effects on potential target organs.

Nitrate in community water supplies and risk of childhood type 1 diabetes in Sardinia, Italy.

We tested the hypothesis of an association between childhood type 1 diabetes (T1D) risk and nitrate concentration in drinking water in Sardinia, Italy, using Poisson regression analysis. Childhood T1D risk showed an inverse trend with increasing quartile of nitrate level in the total population and among men. A nitrate concentration in drinking water below 10 mg/l is unlikely to account for the spatial variation in childhood T1D incidence.

Riskard 2005. New tools for prediction of cardiovascular disease risk derived from Italian population studies.

Background And Aim: The need to update tools for the estimate of cardiovascular risk prompted the "Gruppo di Ricerca per la Stima del Rischio Cardiovascolare in Italia" to produce a new chart and new software called Riskard 2005.

Methods And Results: Data from 9 population studies in 8 Italian regions, for a grand total of 17,153 subjects (12,045 men and 5,108 women) aged 35-74 and for a total exposure of about 194,000 person/years were available. A chart for the estimate of cardiovascular risk (major coronary, cerebrovascular and peripheral artery disease events) in 10 years was produced for men and women aged 45-74 free from cardiovascular diseases.

Epidemiological association between some dietary habits and the increasing incidence of type 1 diabetes worldwide.

Background/aims: The variation in incidence of type 1 diabetes (T1D) worldwide is genetically based. However, its increasing incidence is environmentally determined. Our aim was to describe the role of nutritional habits and of gene-nutrient interactions in the rising incidence of TID.
