Context: Differentiation between familial chylomicronemia syndrome (FCS, type 1 hyperlipoproteinemia), a rare metabolic disorder, and the more common multifactorial severe hypertriglyceridemia (sHTG, type 5 hyperlipoproteinemia) is challenging because of their overlapping symptoms but important in patient management.

Objective: To assess whether readily obtainable clinical information beyond triglycerides can effectively diagnose and differentiate patients with FCS from those with sHTG, based on well-curated data from two intervention studies of these conditions.

Methods: The analysis included 154 patients from two phase 3 clinical trials of patients with sHTG, one cohort with genetically confirmed FCS (n = 49) and one with multifactorial sHTG (n = 105).

Background: Familial chylomicronemia syndrome is a rare genetic disorder that is caused by loss of lipoprotein lipase activity and characterized by chylomicronemia and recurrent episodes of pancreatitis. There are no effective therapies. In an open-label study of three patients with this syndrome, antisense-mediated inhibition of hepatic mRNA with volanesorsen led to decreased plasma apolipoprotein C-III and triglyceride levels.

Objective: Many patients with type 2 diabetes do not reach glycemic goals despite basal insulin treatment. This study assessed the achievement of a target A1C <7.0% (<53 mmol/mol) after initiation of basal insulin in two settings.

Background: Familial chylomicronemia syndrome (FCS) is a rare metabolic disorder caused by mutations in lipoprotein lipase (LPL) or genes required for LPL functionality and is characterized by hyperchylomicronemia that results in recurrent episodes of acute pancreatitis. Owing to the rarity of FCS, there are few case series describing the phenotypic variability in FCS patients in detail.

Objective: To provide baseline characteristics in the largest study population to date of patients with FCS.

Article Synopsis
  • Familial chylomicronemia syndrome (FCS) is a rare genetic condition typically caused by mutations in the LPL gene that affect fat metabolism, with some cases linked to other genes like APOC2 and APOA5.
  • A study evaluated 52 participants with FCS in a clinical trial, finding that 41 had LPL mutations, with results showing all subjects had high triglycerides and chylomicrons but low levels of other lipoproteins.
  • Although LPL-FCS and non-LPL-FCS individuals shared many characteristics, LPL-FCS patients had lower lipoprotein lipase activity and a tendency for higher triglyceride levels, while non-LPL-FCS patients showed higher low-density lipoprote

Background: Epidemiologic and genomewide association studies have linked loss-of-function variants in ANGPTL3, encoding angiopoietin-like 3, with low levels of plasma lipoproteins.

Methods: We evaluated antisense oligonucleotides (ASOs) targeting Angptl3 messenger RNA (mRNA) for effects on plasma lipid levels, triglyceride clearance, liver triglyceride content, insulin sensitivity, and atherosclerosis in mice. Subsequently, 44 human participants (with triglyceride levels of either 90 to 150 mg per deciliter [1.

Chronic hyperglycaemia and glucose variability are associated with the development of chronic diabetes-related complications. We conducted a pooled analysis of patient-level data from three 24-week, randomized, phase III clinical trials to evaluate the impact of lixisenatide (LIXI) on glycaemic variability (GV) vs placebo as add-on to basal insulin. The main outcome GV measures were standard deviation (s.

Objective: To determine the effects of volanesorsen (ISIS 304801), a second-generation 2'-O-methoxyethyl chimeric antisense inhibitor of apolipoprotein (apo)C-III, on triglyceride (TG) levels and insulin resistance in patients with type 2 diabetes.

Research Design And Methods: A randomized, double-blind, placebo-controlled trial was performed in 15 adult patients with type 2 diabetes (HbA1c >7.5% [58 mmol/mol]) and hypertriglyceridemia (TG >200 and <500 mg/dL).

Aim: Despite links to clinical outcomes in patients with type 2 diabetes mellitus (T2DM), the clinical utility of glycaemic variability (GV) measures is unknown. We evaluated the correlation between baseline GV, and glycated haemoglobin (HbA1c) attainment and hypoglycaemic events during treatment intensification in a large group of patients.

Methods: Patient-level data from six 24-week clinical trials of T2DM patients undergoing treatment intensification with basal insulin or comparators (N = 1699) were pooled.

Elevated apoC-III levels predict increased cardiovascular risk when present on LDL and HDL particles. We developed novel high-throughput chemiluminescent ELISAs that capture apoB, lipoprotein (a) [Lp(a)], and apoA-I in plasma and then detect apoC-III on these individual lipoproteins as apoCIII-apoB, apoCIII-Lp(a), and apoCIII-apoAI complexes, respectively. We assessed the effects on these complexes of placebo or 100-300 mg volanesorsen, a generation 2.

Objective: Postprandial hyperglycemia (PPHG) may need addressing when glycemic control cannot be maintained in patients with type 2 diabetes mellitus. We investigated whether glycated hemoglobin A1c (A1c) levels ≥7.0% can indicate postprandial defects warranting prandial therapy after optimized basal insulin therapy.

Background: Here we assess associations between glycemic variability (GV) measures and outcomes from glucose-lowering therapy in patients with type 2 diabetes (T2DM) to identify the metrics most sensitive to treatment response.

Methods: Data from 1699 patients in 6 previously reported studies in adults with T2DM treated with basal insulin and/or oral glucose-lowering drugs were included in a post hoc meta-analysis. Using 7-point blood glucose (BG) profiles we compared the GV metrics standard deviation (SD), mean amplitude of glycemic excursion (MAGE), mean absolute glucose (MAG), low and high BG risk indices (LBGI, HBGI), and average daily risk range (ADRR).

Background: The prevalence of type 2 diabetes mellitus (diabetes) in nursing home residents (NHRs) is increasing, concurrently with obesity and other comorbid conditions. NHR would benefit greatly from antidiabetic medications that would improve glycemic control and give a lower risk of hypoglycemia but that do not contribute to weight gain in obese individuals.

Objective: To examine the prescription patterns to NHRs with diabetes, including the use of newer injectable therapies such as glucagon-like peptide-1 (GLP-1) receptor agonists.

Background: Real-world data on emerging combination approaches for type 2 diabetes mellitus (T2DM) management are limited. The objective of the current study was to document the characteristics and clinical outcomes of patients with T2DM initiating prandial insulin or a glucagon-like peptide-1 (GLP-1) receptor agonist while on basal insulin.

Methods: This was a retrospective analysis of an electronic medical records database of patients with T2DM managed in a community practice setting in the United States.

Background: Treatment of postprandial hyperglycemia could be needed when basal insulin added to oral therapy does not maintain glycated haemoglobin (HbA1C ) targets in type 2 diabetes mellitus. Knowing individual and regional patterns of postprandial hyperglycemia in this setting might improve therapeutic decisions.

Methods: Patient-level self-monitored blood glucose data were pooled from six studies of insulin glargine for patients with HbA1C  ≥ 7.

This study was designed to establish the mechanism responsible for the increased apolipoprotein (apo) A-II levels caused by the cholesteryl ester transfer protein inhibitor torcetrapib. Nineteen subjects with low HDL cholesterol (<40 mg/dl), nine of whom were also treated with 20 mg of atorvastatin daily, received placebo for 4 weeks, followed by 120 mg of torcetrapib daily for the next 4 weeks. Six subjects in the nonatorvastatin cohort participated in a third phase, in which they received 120 mg of torcetrapib twice daily for 4 weeks.
