Type 2 Familial Partial Lipodystrophy (FPLD2), also known as Dunnigan variant, is an autosomal dominant disorder with onset around puberty characterized by absence of adiposity in limbs and trunk with increased face and neck fat deposition, sometimes associated with skeletal muscle hypertrophy and phlebomegaly. Here, we describe a patient with history of severe hypertriglyceridemia (HTG) and type 1 diabetes (T1DM) who developed premature multivessel coronary artery disease (CAD) and ischemic cardiomyopathy, ultimately diagnosed with FPLD2.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Objective/Purpose&lt;/h3&gt;&lt;div&gt;Not applicable to this case study abstract submission.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;Case study.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;LD is a 41-year-old female with newly diagnosed ischemic cardiomyopathy (EF 38%), triple-vessel CAD status-post drug-eluting stent to mid-LAD, severe HTG complicated by recurrent acute pancreatitis, and T1DM. Since childhood, LD reported insatiable appetite despite a thin, muscular frame disproportionate to normal activity. At 19, she was diagnosed simultaneously with T1DM, acute pancreatitis, and severe HTG. Family history was notable for a maternal aunt with similar body morphology and metabolic disease. At evaluation, her only complaint was persistent hunger, though less intense than during early adulthood. Hgb A1C was 7.0% on a continuous insulin pump at 1U/hr requiring minimal bolus dosing for meals. Physical exam was notable for absence of abdominal adiposity below the upper chest with sparing of the head and neck, muscular calf muscles, and prominent peripheral veins, consistent with FPLD2. Figure 1 reports lipid panel on high-intensity statin. She had normal serum creatinine, transaminase levels, thyroid stimulating hormone, and urine albumin-creatinine ratio.

CoQ10 is a component of normal mitochondrial function, and low levels of CoQ10 in muscle tissue have been found in statin associated myopathy (Lamperti et al., 2005). Two reported case studies describe a MELAS-like clinical syndrome that occurred after several months of statin therapy (Chariot et al., 1993; Tsivgoulis et al., 2006). Both developed rhabdomyolysis with elevated CK (20,000 U/L and 45,000-48,000 U/L, respectively).

His mother had severe hyperlipidemia. Baseline lipid panel from 40 years prior showed a total cholesterol of 330 mg/dL and LDL-C of 220 mg/dL. He took rosuvastatin and ezetimibe for over 20 years. His first ACS event five years prior required a left anterior descending artery (LAD) stent. At this time, icosapent ethyl was added and his lipid profile was controlled with apolipoprotein B of 60 mg/dL. However, months later, he required carotid endarterectomy for severe carotid stenosis. Two years later, another LAD stent was placed for new disease in the setting of an LDL-C of 54 mg/dL. After this event, PCSK9 inhibitor was prescribed but denied by insurance. One year later, repeat lipid panel showed: LDL-C 37 mg/dL, apolipoprotein B 66 mg/dL, Lp(a) 297 nmol/L, and hs-CRP 2.6mg/L. PCSK9 inhibitor was denied again so bempedoic acid was added. Lipid apheresis was recommended but denied by insurance. The following year, he had severe two-vessel coronary disease including in-stent restenosis of a prior LAD stent, necessitating coronary artery bypass graft. Two days after surgery, evolocumab was approved and initiated. However, one month later, he required a stent to his bypass graft. Eventually he received insurance approval for lipoprotein apheresis and had significant LDL-C and Lp(a) reduction.</div><div>This case demonstrates that despite optimal lipid and anti-platelet therapy, risk factor control, and invasive treatment, recurrent ACS and plaque progression ensued. This was likely mediated by high Lp(a). Lipoprotein apheresis is the only FDA approved treatment for elevated Lp(a), now with an approved FDA indication for Lp(a) ≥ 60 mg/dL or ≥ 130 nmol/L with coronary or peripheral artery disease, noting a cardiovascular event reduction greater than 75% in such patients. Phase 3 trials are ongoing for Lp(a) lowering agents which will inform future treatment.</div></div><div><h3>Conclusions</h3><div>Patients with FH, elevated Lp(a) and hs-CRP represent an ultra high-risk profile for aggressive atherosclerosis. For our patient, delays in PCSK9 inhibitor and apheresis initiation likely influenced disease progression. Lipoprotein apheresis has demonstrated a reduction in cardiovascular events.</div></div>","PeriodicalId":15392,"journal":{"name":"Journal of clinical lipidology","volume":"19 3","pages":"Pages e37-e38"},"PeriodicalIF":3.6,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144168308","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}

Lp(a) was categorized as normal (&lt; 75 nmol/L), intermediately elevated (75-124 nmol/L), or significantly elevated (&gt; 124 nmol/L), aligned with NLA guidelines. HF stages at Year 5 and Year 30 were defined according to the 2013 AHA/ACC guidelines: stage 0, without risk factors; stage A, HF risk factors; stage B, asymptomatic cardiac structural or functional abnormalities; and stage C/D, symptomatic or end-stage HF. Among those with available data to classify HF stage at Year 5, we evaluated the cross-sectional association between Lp(a) and HF stage. Among those with available HF stages at both Year 5 and Year 30, we evaluated the association between Lp(a) and the change in HF stage from Year 5 to Year 30 (&lt;em&gt;i.e.,&lt;/em&gt; no increase, increase by 1 stage, increase by 2 or more stages) using ordinal logistic regression. All models were stratified by race (Black vs White). Base models adjusted for age and sex, with additional adjustment for HF risk factors (SBP, diabetes, smoking status, total &amp; LDL cholesterol, lipid-lowering medication use).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;We identified 3501 CARDIA participants with both Lp(a) at Year 7 and HF stage at Year 5. 2275 (65%) had normal Lp(a), 584 (16.7%) had intermediately elevated, and 642 (18.3%) had significantly elevated Lp(a) (Figure). At Y5, intermediately elevated Lpa was not associated with higher HF stage in Black (odds ratio [OR]: 1.14, 95% confidence interval [CI]: 0.9, 1.45) or White (OR: 1.10, 95% CI: 0.77, 1.58) participants (interaction p=0.58). Significantly elevated Lp(a) was also not associated with HF stage, and point estimates were slightly but not significantly stronger in White (OR: 1.27, 95% CI: 0.91, 1.78) than in Black (OR: 1.03, 95% CI: 0.82, 1.31) participants. Point estimates for White participants were attenuated after further adjustment for cardiovascular risk factors.
