Based on delayed-onset symptoms and laboratory abnormalities after medication, it is critically-important to consider the possibility of an immune-mediated reaction.

This single center study evaluates 129 patients with a personal or family history of a premature cardiovascular event whose lipoprotein(a) levels were greater than 75nmol/L and prescribed niacin-ER.</p></div><div><h3>Objective/Purpose</h3><p>Identify patients with personal or family history of premature cardiovascular events through history and screen patients for baseline serum lipoprotein(a); levels greater than or equal to 75nmol/L were included. Patients were monitored for incidences of cardiovascular events, elevation of liver enzymes, and side-effects of niacin-ER.</p><p>The study is an effort to determine if niacin-ER can reduce cardiovascular events. While current ASO-RNA and siRNA studies are undergoing trials, niacin-ER may be a less costly alternative.</p></div><div><h3>Methods</h3><p>The study followed 129 adult patients seen by a Board Certified Lipidologist/Cardiologist from 2014-2024 with baseline lipoprotein(a) greater than 75 nmol/L. Patients were started on 1000 mg-2000 mg (mean 1713 mg) of niacin-ER and a high intensity statin. In the study, 118 patients were prescribed niacin-ER, while 11 were a better fit for PCSK-9 therapy. Of the 118 patients, 36 could not tolerate the flushing, despite mitigating strategies. Patients’ hospital and outpatient records were reviewed for cardiovascular events.</p></div><div><h3>Results</h3><p>The average baseline value of lipoprotein(a) was 221.59 nmol/L, higher than 35-70 nmol/L in AIM-HIGH and HPS2-THRIVE trials. Current trials with siRNA and ASO-RNA therapies set inclusion criteria at &gt;150 nmol/L. The average lipoprotein(a) after starting niacin-ER amounted to 157.71 nmol/L, a 33.68% reduction.</p><p>Fifteen patients laboratory tests resulted in non-prohibitive mildly elevated liver function tests (LFTs), with maximum ALT and AST of 85 U/L and 68 U/L, respectively, after starting niacin.</p><p>All patients were on high-intensity statin.</p></div><div><h3>Conclusions</h3><p>Niacin-ER reduced lipoprotein(a) levels by 33.68%, comparable to published data of 30%.</p><p>Niacin-ER continues to be shown as safe and well-tolerated with no incidences of strokes, infections, gastrointestinal symptoms, or rhabdomyolysis; there was a non-significant elevation in LFTs.</p><p>In the 83 patients taking niacin-ER, there were no subsequent cardiovascular events up to ten years follow up.</p><p>Reduction in cardiovascular events could not be observed with the low sample size. The study reinforces the need to further assess the effectiveness of niacin-ER on cardiovascular events while prospective therapies continue through trials.</p></div>","PeriodicalId":15392,"journal":{"name":"Journal of clinical lipidology","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141852369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a case of young woman with a rare instance of familial lipoprotein lipase (LPL) deficiency during pregnancy.</p></div><div><h3>Objective/Purpose</h3><p>Despite that FCS is associated with poor quality of life and increased lifelong risk of sHTG and AP, there is lack of awareness about the disease. We aim to describe clinical features and complications associated with FCS, with the overarching objective of enhancing awareness regarding this condition. Additionally, we explore emerging therapies for the treatment of sHTG.</p></div><div><h3>Methods</h3><p>Literature review and retrospective review of electronic health records were performed.</p></div><div><h3>Results</h3><p>17-year-old Guatemalan female at 25 weeks gestation presented with acute abdominal pain and was found to have a lipase of 4076 mg/dL, amylase of 860 mg/dL and triglyceride (TG) level of 2233 mg/dL requiring apheresis for sHTG induced AP. She re-presented multiple times with sHTG and required treatment for recurrent AP. Genetic testing showed homozygous LPL gene mutation involving novel early truncation and ABCA1 transporter heterozygosity linked to reduced HDL levels. Patient continues to experience a sequela of complications despite treatment with fibrates, statins, omega-3-acid ethyl esters and a low-fat diet.</p></div><div><h3>Conclusions</h3><p>There are currently no treatments for FCS except for lifelong fat restrictive diet. Orlistat, a gastric and pancreatic lipase inhibitor has shown some promise in terms of reducing TG levels. Prior therapies have targeted various phenotypes of sHTG in familial combined hyperlipidemia syndromes with off-label use in FCS. More recently, targeted pharmacotherapies for FCS including apoC-III hepatocyte-directed antisense oligonucleotide such as Volanesorsen (approved in Europe) and Olezarsen (currently in phase-3 trial) have shown promise. Preliminary results from the CORE trials have shown significant reduction in TG levels in FCS patients and 100% reduction in AP. Additionally, small interfering ribonucleic acid (siRNA) based therapies are being studied in patients with FCS.</p><p>Albeit a rare genetic disorder, FCS should be suspected in patients with sHTG in the absence of secondary causes and should be referred to lipid specialists for further management. FCS in pregnancy can pose even more challenges given increased insulin resistance and fetal and maternal burden of disease. Trials for novel targeted therapies have shown encouraging results and may help reduce ASCVD risk and complications associated with FCS.</p></div>","PeriodicalId":15392,"journal":{"name":"Journal of clinical lipidology","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141841924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
