Many drugs affect lipid metabolism and have side effects which promote atherosclerosis. The prevalence of cancer-therapy-related cardiovascular (CV) disease is increasing due to development of new drugs and improved survival of patients: cardio-oncology is a new field of interest and research. Moreover, drugs used in transplanted patients frequently have metabolic implications. Increasingly, internists, lipidologists, and angiologists are being consulted by haematologists for side effects on metabolism (especially lipid metabolism) and arterial circulation caused by drugs used in haematology. The purpose of this article is to review the main drugs used in haematology with side effects on lipid metabolism and atherosclerosis, detailing their mechanisms of action and suggesting the most effective therapies.

Carotid artery plaques are considered a measure of atherosclerosis and are associated with an increased risk of atherosclerotic cardiovascular disease, particularly ischemic strokes. Monitoring of patients with an elevated risk of stroke is critical in developing better prevention strategies. Non-invasive imaging allows us to directly see atherosclerosis in vessels and many features that are related to plaque vulnerability. A large body of evidence has demonstrated a strong correlation between some lipid parameters and carotid atherosclerosis. In this article, we review the relationship between lipids and atherosclerosis with a focus on carotid ultrasound, the most common method to estimate atherosclerotic load.

Background: atherosclerotic process inexorably advances in patients reaching low-density lipoprotein cholesterol (LDL-C) targets. An attractive hypothesis is that lipoprotein particles (very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL)), could contribute to residual risk. The present study aims to investigate the relationship between carotid intima-media thickness (IMT) and different lipoprotein subfractions in a cohort of healthy postmenopausal women. Methods: 75 postmenopausal women, at LDL-C target levels without overt cardiovascular disease, underwent biochemical analyses (including subfraction assay of plasma lipoproteins) and carotid ultrasound examination. Results: a statistically significant correlation between VLDL and carotid IMT (p < 0.001) was found. No significant correlation was found between carotid IMT and LDL-C (p = 0.179), IDL-C (p = 0.815), high-density lipoprotein (HDL) (p = 0.855), and LDL score (p = 0.240). Moreover, IMT is significantly correlated to LDL particle diameter (p = 0.044). After adjusting for age, systolic blood pressure, body mass index, smoking habits, glucose plasma concentration, and Lipoprotein(a) (Lpa) levels, multivariate analysis showed that women in the third tertile of VLDL-C, compared with those in the first tertile, were significantly associated to the highest IMT (p = 0.04). Conclusions: in this cohort of postmenopausal women, VLDL-C was significantly associated to carotid IMT, independent of main cardiovascular risk factors. These findings pave the way for targeting circulating concentrations of VLDL-C to reduce cardiovascular events in patients with target LDL-C levels.

Childhood obesity is associated with an increased carotid intima-media thickness (IMT) and stiffness. Increased carotid wall thickening and rigidity are considered markers of subclinical atherosclerosis. The aim of the present study was to test the effect of two hypocaloric diets of varying glycemic index on weight loss and markers of subclinical atherosclerosis in obese children. Seventy consecutive obese children attending the Outpatient Weight Clinic of the Department of Pediatrics were invited to participate in an intensive dietary protocol. Twenty-six accepted and were randomly assigned to two different groups: the first group followed a hypocaloric low-glycemic index diet and the second a hypocaloric high-glycemic index diet. Anthropometric measures and biochemical tests were performed in all children. Quantitative B-mode ultrasound scans were used to measure intima-media thickness (IMT) and diameters of the common carotid artery. Considering both groups together, at 6 months, body mass index decreased from 28.3 ± 3.1 to 25.8 ± 3.3 kg/m 2 , systolic blood pressure from 119 ± 12 to 110 ± 11 mmHg ( P < 0.001), diastolic blood pressure from 78 ± 8 to 74 ± 7 mmHg ( P < 0.001), IMT from 0.48 ± 0.05 to 0.43 ± 0.07 mm ( P < 0.001), stiffness from 3.57 ± 1.04 to 2.98 ± 0.94 mm ( P = 0.002), and high-sensitivity C-reactive protein from 1.5 ± 0.9 (values log transformed) to 0.4 ± 1.1 ( P < 0.001). No differences were detectable in fasting serum triglycerides, total cholesterol, and high-density lipoprotein cholesterol. Insulin resistance (calculated by the HOmeostatic Model Assessment index [HOMA] score) significantly reduced only in the low-glycemic-index diet group ( P < 0.04). In conclusion, this study confirms a benefit of hypocaloric diets on carotid IMT and stiffness in obese children and demonstrates, for the first time, an amelioration of insulin sensitivity in obese children after a low-glycemic index diet. These results justify the advice to obese children to follow a low-glycemic index diet in order to improve their cardiometabolic profile.

Atherogenic lipoproteins (particularly, very low-density lipoproteins, VLDL) are associated with subclinical atherosclerosis. The present study aims at evaluating whether routinely analysed lipid parameters are associated with carotid intima–media thickness, a proxy for subclinical atherosclerosis. Lipid parameters from 220 post-menopausal women undergoing ultrasound investigation of the carotid arteries were analysed. Forty-five percent of women showed subclinical atherosclerosis on carotid ultrasound. The mean carotid intima–media thickness was 1.26 ± 0.38 mm. The mean value of the non-HDL-C/HDL-C ratio was 3.1 ± 1.2. Univariate analysis showed a significant association between non-HDL-C/HDL-C ratio and intima–media thickness (r = 0.21, p = 0.001). After adjusting for cardiovascular risk factors (age, systolic blood pressure, smoking, body mass index Homeostasis model assessment: insulin resistance and high-sensitivity C-Reactive-Protein), multivariate analysis showed a significant association between non-HDL-C/HDL-C ratio and intima–media thickness (β = 0.039, p = 0.04). Logistic regression analysis showed that the highest tertile of the non-HDL-C/HDL-C ratio was associated with the presence of carotid plaques (OR = 3.47, p = 0.003). Finally, a strong correlation between non-HDL-C/HDL-C ratio and cholesterol bound to VLDL (r = 0.77, p < 0.001) has been found. Non-HDL-C/HDL-C ratio is associated with the presence of carotid atherosclerosis in post-menopausal women and is strongly correlated to VLDL-C levels.

Background/Objectives: Bempedoic acid (BA) is a novel lipid-lowering agent that reduces low-density lipoprotein cholesterol (LDL-c) and cardiovascular events. Limited real-world data on its effectiveness and safety are available. This study aimed to evaluate the utilization and clinical performance of BA in routine clinical practice. Moreover, an explorative pharmacoeconomic analysis was performed. Methods: We prospectively enrolled consecutive patients with dyslipidemia who started 180 mg BA, alone or with 10 mg ezetimibe, across five outpatient clinics in Campania Region, Italy from September to December 2023. Clinical and laboratory assessments, including lipid profile, hepatic function, and creatine phosphokinase levels, were performed at baseline and at least after one month follow-up. Side effects were recorded. Results: 111 patients (age 65 ± 9 years, 61% male) were included. At BA initiation, 70.3% were on maximally tolerated statin dosage and ezetimibe, 16.2% on ezetimibe alone, and 13.5% on PCSK9 inhibitors due to statin intolerance. BA significantly reduced LDL-c serum levels (89.9 ± 33.0 vs. 56 ± 27.6 mg/dL; p < 0.0001), with 46% achieving therapeutic targets. LDL-c decreased by 28% in patients on intensive statins/ezetimibe and by 45% in statin-intolerant patients, with reduced healthcare costs. Side effects were infrequent (10%) and reversible. Adherence was 99%, and persistence 90%. Conclusions: In our clinical pratice, BA was primarily used in high-risk patients with dyslipidemia who failed to reach LDL-c therapeutic target with statins/ezetimibe, and to a lesser extent, in statin-intolerant individuals. BA treatment enabled 54% to reach LDL-c therapeutic target. BA was well tolerated, and showed high adherence and persistence, contributing to cost savings.

Sex: F Age: 65 years. Recent abdominal colic. Petechial-like manifestations with painful discolored skin lesions (suggestive of dermal veins thromboses) on the chest and abdomen. Blood levels of glucose, electrolytes, amylase, lipase, total protein, renal-function tests, the prothrombin time, the international normalized ratio, the partial-thromboplastin time and albumin were normal. Laboratory testing revealed hemolytic anemia: Red cells 2.94 x10⁶/UL; Haemoglobin 8.9 g/dl; Lactate dehydrogenase 950 IU/L. Computed tomography (CT) of the abdomen and pelvis performed after the administration of intravenous contrast material, revealed a central filling defect in the hepatic veins and their branches that was compatible with acute thrombosis of the hepatic veins and their branches. It was suspected paroxysmal nocturnal haemoglobinuria for which flow cytometric analysis was requested.
