Familial hypercholesterolaemia is underdiagnosed and undertreated in the general population: guidance for clinicians to prevent coronary heart diseas…
2013
AIMS: The first aim was to critically evaluate the extent to which familial hypercholesterolaemia (FH) is underdiagnosed and undertreated. The second aim was to provide guidance for screening and treatment of FH, in order to prevent coronary heart disease (CHD).METHODS AND RESULTS: Of the theoretical estimated prevalence of 1/500 for heterozygous FH, <1% are diagnosed in most countries. Recently, direct screening in a Northern European general population diagnosed approximately 1/200 with heterozygous FH. All reported studies document failure to achieve recommended LDL cholesterol targets in a large proportion of individuals with FH, and up to 13-fold increased risk of CHD. Based on prev…
Liraglutide reduces plasma PCSK9 in patients with type 2 diabetes not treated with statins
2022
Dyslipidaemia in type 2 diabetes mellitus (T2DM), which increases cardiovascular risk, includes abnormal metabolism of low-density lipoproteins (LDL). Our group has recently shown that liraglutide increases LDL catabolism in patients with T2DM and that it reduces the expression of PCSK9 (a major inhibitor of LDL-receptor expression) in vitro and in mice. This prompted us to study the effect of liraglutide on plasma PCSK9 level in patients with T2DM.We studied prospectively 82 patients with T2DM (51 without statins, 31 with statins). Plasma PCSK9 and plasma lipids were measured before and six months after the initiation of a treatment with liraglutide at a dose of 1.2 mg/day.Plasma PCSK9 was…
Consenso Delphi sobre el manejo de la dislipidemia en pacientes con alteración del metabolismo de la glucosa: estudio Diana
2016
Objectives The aim of the present study was to develop a multidisciplinary consensus based on the Delphi system to establish clinical recommendations for the management of dyslipidaemia when hyperglycaemia is present, and the relevant factors that should be taken into consideration when prescribing and monitoring treatment with statins. Methods The questionnaire developed by the scientific committee included four blocks of questions about dyslipidaemia in patients with impaired glucose metabolism. The results of the first two blocks are presented here: a) management of dyslipidaemia; b) relevant factors that should be taken into consideration when prescribing and monitoring treatment with s…
GLP-1 receptor agonists in NAFLD.
2017
IF 4.101; International audience; Non-alcoholic fatty liver disease (NAFLD) is very common in patients with type 2 diabetes (T2D), with approximately two-thirds having a diagnosis of the disease. Currently, the only validated treatment for NAFLD is weight loss. A number of studies of animal models and human trials have evaluated the effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on liver fat content and suggest that the treatment could represent a new alternative for NAFLD management. In this review, our focus is on the main studies regarding the effects of GLP-1RAs on NAFLD. Also, the mechanisms that might explain their beneficial effects on liver diseases are analyzed.
Xanthine Oxidase Is Involved in Free Radical Production in Type 1 Diabetes
2002
The aim of this work was to study the mechanism of free radical formation in type 1 diabetes and its possible prevention. We have found oxidation of blood glutathione and an increase in plasma lipoperoxide levels in both human type 1 diabetes and experimental diabetes. Peroxide production by mitochondria does not increase in diabetes. On the contrary, the activity of xanthine oxidase, a superoxide-generating enzyme, increases in liver and plasma of diabetic animals. The increase in plasma xanthine oxidase activity may be explained by the increase in the hepatic release of this enzyme, which is not due to nonspecific membrane damage: release of other hepatic enzymes, such as the amino transf…
Renal artery denervation for treating resistant hypertension: Definition of the disease, patient selection and description of the procedure
2012
Arterial hypertension is responsible for a significant burden of cardiovascular morbidity and mortality, worldwide. Although several rational and integrated pharmacological strategies are available, the control of high blood pressure still remains largely unsatisfactory. Failure to achieve effective blood pressure control in treated hypertensive patients may have a substantial impact on individual global cardiovascular risk, since it significantly increases the risk of developing hypertension-related macrovascular and microvascular complications. Arterial hypertension is arbitrarily defined as 'resistant' or 'refractory' when the recommended blood pressure goals (clinic blood pressure below…
Dental considerations for the patient with renal disease
2011
Chronic renal disease (CRD) is the renal disease that manifests oral consequences most frequently, and it is defined as a progressive and irreversible decline in renal function associated with a reduced glomerular filtration rate (GFR). The most frequent causes of CRD are diabetes mellitus, arterial hypertension and glomerulonephritis. CRD is classified in 5 stages – from kidney damage with normal or increased GFR to renal failure. In order to quantify the CRD, renal function is measured using the GFR, which is estimated using creatinine clearance (CC). This CC is used for dose adjustment of drugs. In dental practice, the function of the kidneys can be measured indirectly through plasmatic …
Involvement of Oxysterols and Lysophosphatidylcholine in the Oxidized LDL–Induced Impairment of Serum Albumin Synthesis by HEPG2 Cells
2000
Abstract —Oxidized low density lipoproteins (Ox-LDLs) are increasingly thought to be a key element in atherogenesis. We have previously reported that serum albumin has important antioxidant properties and that a reduced synthesis of albumin may represent a crucial point in the overall antioxidant defense. In the present work, we aimed at determining whether Ox-LDL could modulate albumin synthesis in cultured human hepatocytes (HepG2 cells). With the use of enzyme immunoassay and radiolabeled leucine incorporation followed by specific immunoprecipitation, Ox-LDL was found to lead to a dose-dependent decrease in albumin secretion. Moreover, the protein synthesis and mRNA levels were decrease…
Lipoic Acid Improves Nerve Blood Flow, Reduces Oxidative Stress, and Improves Distal Nerve Conduction in Experimental Diabetic Neuropathy
1995
OBJECTIVE To determine whether lipoic acid (LA) will reduce oxidative stress in diabetic peripheral nerves and improve neuropathy. RESEARCH DESIGN AND METHODS We used the model of streptozotocin-induced diabetic neuropathy (SDN) and evaluated the efficacy of LA supplementation in improving nerve blood flow (NBF), electrophysiology, and indexes of oxidative stress in peripheral nerves affected by SDN, at 1 month after onset of diabetes and in age-matched control rats. LA, in doses of 20, 50, and 100 mg/kg, was administered intraperitoneally five times per week after onset of diabetes. RESULTS NBF in SDN was reduced by 50% LA did not affect the NBF of normal nerves but improved that of SDN i…
Osteonecrosis of the jaws in patients assuming oral bisphosphonates for osteoporosis: A retrospective multi-hospital-based study of 87 Italian cases
2013
Abstract Background Bisphosphonates (BPs) are currently the chief drugs for the prevention/treatment of osteoporosis; one of their adverse effects is the osteonecrosis of the jaw (BRONJ). The primary endpoints of this multi-center cross-sectional study are: i) an observation of the clinical features of BRONJ in 87 osteoporotic, non-cancer patients; and ii) an evaluation of their demographic variables and comorbidities. Methods 87 BRONJ patients in therapy for osteoporosis with BPs from 8 participating clinical Italian centers were consecutively identified and studied. After BRONJ diagnosis and staging, comorbidities and data relating to local and drug-related risk factors for BRONJ were col…
