RESUMEN

Indigenous Australians are known to have a higher prevalence of coronary artery disease (CAD) than non-Indigenous counterparts. Atherogenic lipid profiles, characterised by low serum levels of high-density lipoprotein (HDL) and higher serum triglycerides, have been shown to be more prevalent in Indigenous Australians. The use of computed tomography coronary angiography (CTCA) for risk stratification and diagnosis of CAD has been validated in moderate risk populations, but limited data exists in specific high-risk populations such as Indigenous Australians. Through a retrospective study of patient records, we aimed to confirm if an atherogenic lipid profile occurred in Indigenous Australians undergoing CTCA in the Northern Territory of Australia and if so, whether this correlated with the prevalence or burden of CAD. We demonstrate that Indigenous Australians have similar prevalence (52.6% vs. 50.3%, P=0.80) and burden of CAD (Leaman score 6.03±4.66 vs. 6.96±4.82, P=0.44) on CTCA as non-Indigenous patients, but were 8 years younger (41.9±8.9 vs. 50.0±11.9 years, P<0.001) at the time of examination. We confirmed the presence of an atherogenic lipid profile in Indigenous patients and showed low serum-HDL was associated with very premature (patients aged 18-35 years) CAD in comparison to premature (patients aged 36-55 years) and mature-onset (patients aged 56 years and older) CAD (0.71±0.25 vs. 1.09±0.35 vs. 1.18±0.36 mmol/L, P=0.009). Future clinical guidelines should consider the role of CTCA in Indigenous Australians and whether younger patients may benefit. The causes of premature CAD, including atherogenic lipid profiles, require an ongoing focus in order to achieve equitable cardiovascular outcomes for Indigenous and non-Indigenous Australians.

RESUMEN

AIMS: Across its operational span of more than 25 years, the observational, nationwide, multicentre Finnish Diabetic Nephropathy (FinnDiane) Study has aimed to unravel mechanisms underlying diabetic kidney disease, with a special focus on its metabolic risk factors. We sought to compile key findings relating to this topic and to offer a current perspective on the natural course of diabetic kidney disease among individuals with type 1 diabetes. METHODS: In this narrative review, articles relevant to the subject published by the FinnDiane Study were identified and summarized together with work published by others, when relevant. RESULTS: The FinnDiane Study has underscored the significance of dysglycaemia and insulin resistance, increased visceral fat mass, hypertension and dyslipidaemia-particularly high triglycerides and remnant cholesterol-as risk factors for diabetic kidney disease. Factors like abdominal obesity seem to influence the early stages of the disease, while the presence of the metabolic syndrome becomes implicated at later stages. Epidemiological reports have revealed that after an initial decline, the cumulative incidence of albuminuria plateaued post-1980s, with the progression rate to kidney failure remaining high. Fortunately, 23% of the FinnDiane cohort regressed to less advanced stages of albuminuria, improving their overall prognosis. CONCLUSION: A substantial burden of albuminuria associated with type 1 diabetes persists, and therefore, novel kidney-protecting therapies are highly awaited. In addition, given that metabolic factors influence the progression of diabetic kidney disease both in its early and advanced stages, emphasis should be placed on ensuring that their treatment targets are met.

RESUMEN

Introduction: Obesity, dyslipidaemia and insulin resistance are associated with hypopituitarism. The association between these conditions and Sheehan's syndrome (SS) caused by post-partum pituitary gland necrosis is poorly understood. This study aimed to assess cardiovascular risk surrogate markers in SS patients, and we compared clinical, biochemical and radiological testing with healthy controls. Methods: In this cross-sectional study, we studied 45 patients with SS on standard replacement therapy and compared them with healthy controls. All subjects underwent anthropometric, inflammatory marker and hormonal measurement (adrenocorticotropic hormone (ACTH), stimulated cortisol, insulin-like growth factor-1 (IGF-1), thyroxine (T4), follicle-stimulating hormone (FSH), luteinising hormone (LH), oestradiol (E2), prolactin (Prl), insulin, interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP)). Carotid intima-media thickness (CIMT), flow-mediated dilation (FMD) and echocardiography were also performed. Results: The mean age and body mass index (BMI) of SS patients were 48.1 ± 10.0 years and 24.3 ± 4.3 kg/m2, respectively, while those of controls were 44.6 ± 12.0 years and 24.6 ± 3.2 kg/m2, respectively. Systolic blood pressure was significantly higher in SS (124.6 ± 20.8 vs. 117.0 ± 18.6 mm of Hg, P < 0.05). All SS patients were hypothyroid, and all except one were hypocortisolaemic. Triglyceride (TG) levels were significantly higher in SS patients (165.6 ± 83.3 vs. 117.2 ± 56.1, P < 0.01), but no difference in the prevalence of metabolic syndrome (MetS) was found. hs-CRP (9.1 (5.2-18.5) vs. 1.5 (0.6-2.8), P < 0.001) and IL-6 (4.9 (3.7-7.3) vs. 3.1 (2.0-4.2), P < 0.001) were significantly higher in SS patients. CIMT was significantly increased in SS patients, but no difference in FMD was found. Echocardiography revealed no significant difference in left ventricular (LV) dimensions, interventricular thickness, posterior wall thickness, ejection fraction, LV mass and diastolic function. Conclusion: SS patients show increased cardiovascular risk with hypertension, dyslipidaemia and increased atherosclerotic and inflammatory markers.

RESUMEN

Background: Significant challenges are associated with the pharmacological management of dyslipidemia, an important risk factor for cardiovascular disease. Limited reliable evidence exists regarding the efficacy of red yeast rice (RYR)-containing commercial Chinese polyherbal preparation (CCPP), despite their widespread use in China. Purpose: We aimed to investigate the efficacy of RYR-containing CCPPs combined with statins in treating dyslipidemia. Methods: Eight databases were searched for relevant randomized controlled trials (RCTs) from database inception date to November 2023. Outcome measures, including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglyceride (TG), clinical efficacy, and adverse reactions, were assessed. The Cochrane Handbook for Systematic Reviews of Interventions was used for quality evaluation, and the meta-analysis was conducted using RevMan 5.3 and Stata 15.1. Results: Thirty-three studies involving 4,098 participants were included. The combination of RYR-containing CCPP, such as Xuezhikang (XZK), Zhibitai (ZBTAI), or Zhibituo (ZBTUO) with statins had a significant effect on the increase in clinical efficacy [RR:1.16, 95%CI (1.13, 1.19), p < 0.00001]. In addition, they also improved blood lipid profile parameters by increasing HDL-C levels [MD:0.21, 95%CI(0.17, 0.25), p < 0.00001], and decreasing TC [MD: 0.60, 95%CI(-0.76, -0.45), p < 0.00001], TG [MD: 0.33, 95%CI(-0.39, -0.26), p < 0.00001] and LDL-C levels [MD: 0.45, 95%CI(-0.54, -0.36), p < 0.00001]. No significant adverse reactions was observed in the RYR-containing CCPPs. Notably, ZBTAI and XZK significantly reduced the incidence of gastrointestinal disturbances and muscular adverse reactions. However, subgroup analyses suggested that the type of CCPPs, dose, and treatment duration might affect the efficacy of RYR-containing CCPPs. Conclusion: RYR-containing CCPPs combined with statins appears to improve lipid profiles and clinical efficacy in patients with dyslipidemia. However, due to the poor quality of the included studies, and some studied showing negative findings was unpublished. The results should be interpreted with caution until further confirmation by well-designed RCTs.

RESUMEN

Coenzyme Q10 (CoQ) is a ubiquitous lipid with different biological functions. In blood, there is a close relationship between CoQ status and cholesterol, which strongly supports the study of both molecules simultaneously. The objective of this study was to evaluate plasma CoQ, lipoprotein concentrations and CoQ/Chol ratio in a cohort of paediatric patients with different types of dyslipidaemias. A total of 60 paediatric patients were recruited (age range: 7 months-18 years), including 52 with different types of hypercholesterolemia, 2 with isolated hypertriglyceridemia and 6 with hypobetalipoproteinemia. Plasma CoQ was analysed by HPLC with electrochemical detection, and lipoprotein and cholesterol concentrations by standard automated methods. The lowest CoQ values were detected in patients with hypobetalipoproteinemia and in two cases of liver cirrhosis. Mean CoQ values were significantly higher in hypercholesterolemic patients compared to controls (average values 1.07 µmol/L and 0.63 µmol/L) while the CoQ/cholesterol ratio did not show differences (170 vs. 163, respectively). Mean CoQ values were significantly lower in the group of patients with hypobetalipoproteinemia compared to controls (mean CoQ values of 0.22 µmol/L vs. 0.63 µmol/L, respectively), while those of CoQ/cholesterol did not show differences. Pearson's correlation test showed a positive correlation between the CoQ and cholesterol values (r = 0.565, p < 0.001) and between the CoQ and the LDL cholesterol values (r = 0.610, p < 0.001). Our results suggest that it is advisable to analyse plasma CoQ and cholesterol concentrations in patients with hypobetalipoproteinemia and hypercholesterolemia associated with liver damage.

RESUMEN

Background: Altered lipid levels may be associated with the development of a number of malignancies, including cancer of the cervix. However, there is limited understanding of this relationship in the rural Ugandan context. Objective: We investigated the connection between dyslipidaemias and cervical intraepithelial neoplasia (CIN) among women attending the cervical cancer clinic at Mbarara Regional Referral Hospital in south-western Uganda. Methods: This unmatched case-control study was conducted between December 2022 and February 2023 and included women with CIN (cases) and women without intraepithelial lesions (controls) in a 1:1 ratio. Participants were selected based on cytology and/or histology results, and after obtaining written informed consent. Demographic data were collected, and venous blood was drawn for lipid profile analysis. Dyslipidaemia was defined as: total cholesterol > 200 mg/dL, low-density lipoprotein > 160 mg/dL, triglycerides > 150 mg/dL, or high-density lipoprotein < 40 mg/dL. At diagnosis, cases were categorised as either CIN1 (low grade) or CIN2+ (high grade). Results: Among the 93 cases, 81 had CIN1, while 12 had CIN2+. Controls had a 13.9% (13/93) prevalence of high triglycerides and cases had a prevalence of 3.2% (3/93; p = 0.016). Reduced high-density lipoprotein was the most prevalent dyslipidaemia among cases (40.9%; 38/93). Statistically significant associations were found between high serum triglycerides and CIN (odds ratio: 1.395, 95% confidence interval: 0.084-1.851, p = 0.007). Conclusion: A notable association was observed between triglyceride dyslipidemia and CIN. Further studies into biochemical processes and interactions between lipids and cervical carcinogenesis are recommended through prospective cohort studies. What this study adds: This research provides additional information on the potential role of lipids in cervical carcinogenesis among women in rural Uganda. It also presents the possible prevalence of multimorbidity involving cervical cancer and cardiovascular diseases, particularly in low-resource settings lacking preventive measures against the increasing prevalence of dyslipidaemia.

RESUMEN

BACKGROUND: Acute coronary syndrome (ACS) is a type of coronary heart disease (CHD), which is responsible for one-third of total deaths in people older than 35 years. Even though cardiac troponin is the gold standard for myocardial necrosis it is blind for ischemia without necrosis. Studies demonstrate that Ischaemia Modified Albumin (IMA) is more sensitive in diagnosing ischemic chest pain compared to cardiac troponin T and electrocardiogram, and its combination with these tests significantly increases the sensitivity for diagnosing unstable angina, non-ST-elevation myocardial infarction (NSTEMI), or ST-elevation myocardial infarction (STEMI), with high positive and negative predictive values, making it a valuable tool for ruling out ACS in patients with inconclusive diagnoses in the emergency department. METHODS: This prospective cohort study, conducted at the Teaching Hospital, Peradeniya, Sri Lanka, from 2015 to 2019, investigated ischemia-modified albumin (IMA) levels in 330 acute coronary syndrome (ACS) patients. Excluding those with various chronic conditions and those on specific medications, serum IMA was analyzed using a colorimetric assay based on cobalt (II) binding to human serum albumin affected by myocardial ischemia. Serum IMA levels were measured, and statistical analyses, including non-parametric tests and correlation analyses, were conducted to evaluate the association between IMA levels and various demographic and clinical factors. RESULTS: IMA concentrations were found to be non-normally distributed, with an average concentration of 0.252 ± 0.123 AU. No overall significant gender-based difference in IMA levels was observed, though within the younger age group (< 59 years), males exhibited higher IMA concentrations than females. Significant gender differences were observed in the younger age group, with males showing higher IMA levels than females (p = 0.033). No significant differences in IMA levels were found across different ethnicities (p = 0.217) or BMI categories (p = 0.056). A significant increase in IMA levels was noted in ACS patients compared to control subjects (p < 0.001). Correlation analysis revealed significant associations between IMA levels and total cholesterol (r = 0.262, p = 0.009) and low-density lipoprotein (LDL) levels (r = 0.280, p = 0.006). Notably, a significant gender difference in IMA levels was found in obese patients, suggesting physiological differences in response to obesity. The study also revealed higher IMA concentrations in NSTEMI and STEMI patients compared to those with unstable angina. CONCLUSION: The study confirms elevated IMA levels in ACS patients, supporting its diagnostic potential. It reveals demographic influences, such as higher IMA levels in younger males and significant gender-specific differences in obese patients. Personalized approaches considering demographics and lipid management are essential for ACS risk reduction and IMA's role in management.

RESUMEN

Background: We compared the efficacy and safety profiles of ainuovirine (ANV), a new-generation non-nucleoside reverse transcriptase inhibitor (NNRTI), with boosted elvitegravir (EVG), both coformulated with two nucleoside reverse transcriptase inhibitors (NRTIs), in people living with HIV-1 (PLWH) who had achieved virological suppression on previous NNRTI-based antiretroviral (ARV) regimen. Methods: This study was a multi-centre, randomised, double-blind, active-controlled, non-inferiority trial recruiting PLWH from 10 clinical centres across China. Main inclusion criteria included age of 18-65 years (inclusive), and stably staying on an ARV regimen combining an NNRTI with a two-drug NRTI backbone for at least 12 months. Eligible participants must have maintained plasma HIV-1 ribonucleic acid (RNA) titre below 50 copies per mL confirmed on two successive tests at an interval of at least one month prior to randomisation. Participants were randomly assigned to receive ANV 150 mg plus lamivudine (3TC) 300 mg, and tenofovir disoproxil fumarate (TDF) 300 mg (ANV/3TC/TDF), or cobicistat (Cobi) 150 mg boosted EVG plus emtricitabine (FTC) 200 mg, and tenofovir alafenamide (TAF) 10 mg. The primary efficacy endpoint was the proportion of participants with HIV-1 RNA titre at 50 copies per mL or above at week 48 using the US Food and Drug Administration snapshot algorithm, with a non-inferiority margin of 4 percentage points at a two-side 95% confidence level. This trial is active, but not recruiting, and is registered with Chinese Clinical Trial Registry (ChiCTR), number ChiCTR2100051605. Findings: Between October 2021 and February 2022, 923 patients were screened for eligibility, among whom 762 participants were randomized and had received at least one dose of ANV/3TC/TDF (n = 381) or EVG/Cobi/FTC/TAF (n = 381). At week 48, 7 (1.8%) participants on ANV/3TC/TDF and 6 (1.6%) participants on EVG/Cobi/FTC/TAF had plasma HIV-1 RNA titre at 50 copies per mL or above, including missing virological data within the time window (the Cochran-Mantel-Haenszel method, estimated treatment difference [ETD], 0.3%, 95% CI -1.6 to 2.1), establishing the non-inferiority of ANV/3TC/TDF to EVG/Cobi/FTC/TAF. The proportions of participants experiencing at least one treatment-emergent adverse events (AEs) were comparable between the two arms (97.6% versus 97.6%). A small proportion of participants discontinued study drug due to AEs (0.3% versus 0.3%). Serious AEs occurred in 11 (2.9%) participants on ANV/3TC/TDF and 9 (2.4%) participants on EVG/Cobi/FTC/TAF, respectively, none of which was considered related to study drug at the jurisdiction of the investigator. At week 48, participants on ANV/3TC/TDF showed a significantly less weight gain from baseline compared to those on EVG/Cobi/FTC/TAF (least square mean, 1.16 versus 2.05 kg, ETD -0.90 kg, 95% CI, -1.43 to -0.37). The changes in serum lipids from baseline also favoured ANV/3TC/TDF over EVG/Cobi/FTC/TAF. Interpretation: In virologically suppressed PLWH on previous NNRTI-based ARV regimen, switch to ANV/3TC/TDF resulted in less weight gain, and improved lipid metabolism while maintaining virological suppression non-inferior to that to EVG/Cobi/FTC/TAF.

RESUMEN

Diabetes mellitus is a metabolic disorder characterized by elevated blood glucose that has sequelae on cellular, haematological, and metabolic parameters, including lipid profile disturbed homeostasis, which manifest in alterations in haematological parameters and lipid profiles. These changes in haematological parameters and lipid profiles have been reported by previous research; however, the pattern of these changes and their correlation have not been elucidated. This review aims to assess these changes and investigate the degree of correlation between haematological parameters and lipid profiles in patients with type 2 diabetes mellitus (T2DM). The method adopted was a traditional review approach that included a narrative of concepts and a critical assessment of a few selected articles. Findings highlight that haematological parameters and lipid profiles show varied alterations and correlations in T2DM. For instance, statistical significances at p < 0.05 are reported for WBC count (r = -0.75) showing negative correlations (p < 0.001), where RBC count (r = 0.56) showed correlation with high-density lipoprotein cholesterol (HDLC), whereas anaemia (packed cell volume: r = -0.51) and RBC indices (mean corpuscular volume: r = -0.75; mean corpuscular haemoglobin: r = -089) show negative correlations with total cholesterol (TC). The specific haematological parameters, namely, RBC and WBC with differential and platelet counts, as well as indices, showed varied changes and correlation with lipid profiles, namely, HDLC, low-density lipoprotein cholesterol, TC, and triglyceride, in the six reviewed articles. Diabetes is characterized by changes in haematological parameters and lipid profiles. A better understanding of the negative and positive correlating changes could be utilized in routine evaluation of subjects with prediabetes as well as managing complications in diabetes. Correlation between haematological parameters and lipid profiles over the course of diabetes progression using HbA1c as an index of glucose control is necessary for additional empirical data and updates.

RESUMEN

BACKGROUND AND AIMS: It has been reported that patients without standard modifiable cardiovascular (CV) risk factors (SMuRFs-diabetes, dyslipidaemia, hypertension, and smoking) presenting with first myocardial infarction (MI), especially women, have a higher in-hospital mortality than patients with risk factors, and possibly a lower long-term risk provided they survive the post-infarct period. This study aims to explore the long-term outcomes of SMuRF-less patients with stable coronary artery disease (CAD). METHODS: CLARIFY is an observational cohort of 32 703 outpatients with stable CAD enrolled between 2009 and 2010 in 45 countries. The baseline characteristics and clinical outcomes of patients with and without SMuRFs were compared. The primary outcome was a composite of 5-year CV death or non-fatal MI. Secondary outcomes were 5-year all-cause mortality and major adverse cardiovascular events (MACE-CV death, non-fatal MI, or non-fatal stroke). RESULTS: Among 22 132 patients with complete risk factor and outcome information, 977 (4.4%) were SMuRF-less. Age, sex, and time since CAD diagnosis were similar across groups. SMuRF-less patients had a lower 5-year rate of CV death or non-fatal MI (5.43% [95% CI 4.08-7.19] vs. 7.68% [95% CI 7.30-8.08], P = 0.012), all-cause mortality, and MACE. Similar results were found after adjustments. Clinical event rates increased steadily with the number of SMuRFs. The benefit of SMuRF-less status was particularly pronounced in women. CONCLUSIONS: SMuRF-less patients with stable CAD have a substantial but significantly lower 5-year rate of CV death or non-fatal MI than patients with risk factors. The risk of CV outcomes increases steadily with the number of risk factors.

RESUMEN

The discovery of RNA interference in 1998 opened avenues for the manipulation of gene expression, leading to the development of small interfering RNA (siRNA) drugs. Patisiran, the first FDA-approved siRNA medication, targets hereditary transthyretin amyloidosis with polyneuropathy. Givosiran, lumasiran and nedosiran further expand siRNA applications in treating rare genetic diseases, demonstrating positive outcomes. In cardiology, inclisiran, approved for hypercholesterolaemia, showcases sustained reductions in LDL cholesterol levels. However, ongoing research aims to establish its impact on cardiovascular outcomes. Lipoprotein(a), an independent risk factor for atherosclerotic cardiovascular disease, has become a focus of siRNA therapies, precipitating the development of specific siRNA drugs like olpasiran, zerlasiran and lepodisiran, with promising reductions in lipoprotein(a) levels. Research to assess the effectiveness of these medications in reducing events is currently under way. Zodasiran and plozasiran address potential risk factors for cardiovascular diseases, targeting triglyceride-rich lipoproteins. Zilebesiran, which targets hepatic angiotensinogen mRNA, has demonstrated a dose-related reduction in serum angiotensinogen levels, thereby lowering blood pressure in patients with systemic arterial hypertension. The evolving siRNA methodology presents a promising future in cardiology, with ongoing studies assessing its effectiveness in various conditions. In the future, larger studies will provide insights into improvements in cardiovascular outcomes, long-term safety and broader applications in the general population. This review highlights the historical timeline of the development of siRNA-based drugs, their clinical indications, potential side-effects and future perspectives.

RESUMEN

BACKGROUND AND AIMS: Cardiovascular diseases (CVD) risk factors include high cholesterol. Children with total cholesterol (TC) levels ≥ 170 mg/dL are usually considered hypercholesterolemic. This study aimed at investigating the awareness of TC levels in a large Italian paediatric population and at looking for a possible correlation between their TC and TC in their parents' blood. METHODS AND RESULTS: A survey was carried out in 46,309 subjects (mean age 9.7 ± 2.3 years; age range 6-14 years) to check the awareness of their own TC levels by using a personal and family medical history questionnaire. In 95.67% of the sample TC value was unknown. In 2.69% TC was < 170 mg/dL, whereas 1.64% were hypercholesterolemic (TC ≥ 170 mg/dL). A statistically significant correlation was found between children with normal TC values and physiological TC values in both parents (p < 0.0001). Again, a significant association between children with high TC and their parents with high TC was detected when parents were analysed separately (i.e. children with TC ≥ 170 mg/dl vs maternal TC ≥ 200 mg/dL: OR 2.01 (95% CI 1.61-2.49, p < 0.001); children with TC ≥ 200 mg/dl vs maternal TC ≥ 240 mg/dL: OR 3.14 (95% CI 2.14-4.6, p < 0.001); children with TC ≥ 170 mg/dl vs paternal TC ≥ 200 mg/dL: OR 2.39 (95% CI 1.91-2.98, p < 0.001); children with TC ≥ 200 mg/dl vs paternal TC ≥ 240 mg/dL: OR 3.85 (95% CI 2.70-5,.50, p < 0.001). CONCLUSION: Just a minority of the investigated young patients knew their TC. This is worrisome. Children with normal TC values are more likely to be born from healthy parents with physiological TC. In addition, high TC in the enrolled subjects is significantly associated with high TC in their parents. Overall, these findings seem to highlight the importance of health education and genetics in TC pathogenesis.

RESUMEN

BACKGROUND: Diabetes mellitus is generally accompanied by dyslipidaemia, but inconsistent relationships between lipid profiles and diabetes are noted. Moreover, genetic variations in insertion/deletion (I/D) polymorphisms at angiotensin-converting enzyme gene (ACE) and T/C polymorphisms in the angiotensin type 1 receptor gene (AGTR1) are related to diabetes and lipid levels, but the associations are controversial. Thus, the current research aimed to explore the effects of ACE I/D, AGTR1 rs5182 and diabetes mellitus on serum lipid profiles in 385 Chinese participants with an average age of 75.01 years. METHODS: The ACE I/D variant was identified using the polymerase chain reaction (PCR) method, whereas the AGTR1 rs5182 polymorphism was identified using the PCR-based restriction fragment length polymorphism (PCR-RFLP) method and verified with DNA sequencing. Total cholesterol (TC), triglyceride (TG), apolipoprotein A (ApoA), apolipoprotein B (ApoB), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were measured using routine methods, and the lipid ratios were calculated. RESULTS: ACE I/D, but not AGTR1 rs5182, was a predictor of TG/HDL-C for the whole study population. Both ACE I/D and AGTR1 rs5182 were predictors of HDL-C and LDL-C levels in females but not in males. Moreover, in females, diabetes mellitus and ACE I/D were identified as predictors of TG and TG/HDL-C, whereas AGTR1 rs5182 and diabetes mellitus were predictors of TG/HDL-C. Moreover, diabetes mellitus and the combination of ACE I/D and AGTR1 rs5182 variations were predictors of TG and TG/HDL-C exclusively in females. CONCLUSIONS: The results demonstrated the potential for gender-dependent interactions of ACE I/D, AGTR1 rs5182, and diabetes on lipid profiles. These findings may serve as an additional explanation for the inconsistent changes of blood lipids in individuals with diabetes mellitus, thereby offering a novel perspective for the clinical management of blood lipid levels in diabetic patients.

RESUMEN

BACKGROUND: The optimal statin treatment strategy that is balanced for both efficacy and safety has not been clearly determined in older adults with coronary artery disease (CAD). METHODS: In the post hoc analysis of the LODESTAR (low-density lipoprotein cholesterol-targeting statin therapy versus intensity-based statin therapy in patients with coronary artery disease) trial, the impact between a treat-to-target strategy versus a high-intensity statin therapy strategy was compared in older adults (aged 75 years or older). The goal of treat-to-target low-density lipoprotein cholesterol (LDL-C) level was 50-70 mg/dl. The primary endpoint comprised the three-year composite of all-cause death, myocardial infarction, stroke or coronary revascularisation. RESULTS: Among 4,400 patients with CAD enrolled in the LODESTAR trial, 822 (18.7%) were aged 75 years or older. Poor clinical outcomes and risk factors for atherosclerosis were more frequently observed in older adults than in younger population (<75 years old). Among these older adults with CAD, the prescription rate of high-intensity statin was significantly lower in the treat-to-target strategy group throughout the study period (P < 0.001). The mean LDL-C level for three years was 65 ± 16 mg/dl in the treat-to-target strategy group and 64 ± 18 mg/dl in the high-intensity statin group (P = 0.34). The incidence of primary endpoint occurrence was 10.9% in the treat-to-target strategy group and 12.0% in the high-intensity statin group (hazard ratio 0.92, 95% confidence interval 0.61-1.38, P = 0.69). CONCLUSIONS: High-intensity statin therapy is theoretically more necessary in older adults because of worse clinical outcomes and greater number of risk factors for atherosclerosis. However, the primary endpoint occurrence with a treat-to-target strategy with an LDL-C goal of 50-70 mg/dl was comparable to that of high-intensity statin therapy and reduced utilisation of a high-intensity statin. Taking efficacy as well as safety into account, adopting a tailored approach may be considered for this high-risk population. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02579499.

RESUMEN

People living with type 1 diabetes (T1D) have an increased risk of cardiovascular disease (CVD), and it is the leading cause of morbidity and mortality in this population. CVD risk increases with each uncontrolled risk factor, even in individuals with good glycaemic control. Recommendations for assessing CVD risk in the T1D population are extended from those for type 2 diabetes (T2D) even though the physiopathology and underlying mechanisms of atherosclerosis in T1D are poorly understood and differ from those in T2D. Unlike the assessment of microvascular complications, which is well established in T1D, this is far from being the case for the comorbidities and risk associated with CVD. Aside from classical cardiovascular comorbidities, carotid ultrasound can be useful to stratify CVD risk. The utilization of specific risk scales such as the Steno Type 1 Risk Engine can help to more accurately classify cardiovascular risk in these individuals. The cornerstones of the management of cardiovascular risk in T1D are the promotion of the Mediterranean diet, tight glycaemic control (glycated haemoglobin (HbA1c) < 7%), blood pressure < 130/80 mmHg in most patients, and low-density lipoprotein (LDL) cholesterol < 100 mg/dL in moderate-risk individuals, < 70 mg/dL in high-risk individuals, and < 55 mg/dL in very high-risk individuals. Conventional medical follow-up of patients with T1D should be individualized (approximately 2-3 visits per year), and a carotid ultrasound evaluation is recommended every 5 years in the absence of significant preclinical atherosclerosis or more often in those with severe preclinical atherosclerosis. Antithrombotic therapy is recommended in those receiving secondary prevention, those with stenosis > 50% in any arterial bed, and those with an impaired ankle-brachial index. This document is a proposal of a practical approach for the evaluation, classification, and management of CVD risk in individuals living with T1D.

RESUMEN

AIM: To perform a meta-analysis to investigate the effects of intermittent fasting (IF), as compared with either a control diet (CON) and/or calorie restriction (CR), on body composition and cardiometabolic health in individuals with prediabetes and type 2 diabetes (T2D). METHODS: PubMed, Web of Science, and Scopus were searched from their inception to March 2024 to identify original randomized trials with parallel or crossover designs that studied the effects of IF on body composition and cardiometabolic health. Weighted mean differences (WMDs) or standardized mean differences with 95% confidence intervals (CIs) were calculated using random-effects models. RESULTS: Overall, 14 studies involving 1101 adults with prediabetes or T2D were included in the meta-analysis. IF decreased body weight (WMD -4.56 kg [95% CI -6.23 to -2.83]; p = 0.001), body mass index (BMI; WMD -1.99 kg.m2 [95% CI -2.74 to -1.23]; p = 0.001), glycated haemoglobin (HbA1c; WMD -0.81% [95% CI -1.24 to -0.38]; p = 0.001), fasting glucose (WMD -0.36 mmol/L [95% CI -0.63 to -0.09]; p = 0.008), total cholesterol (WMD -0.31 mmol/L [95% CI -0.60 to -0.02]; p = 0.03) and triglycerides (WMD -0.14 mmol/L [95% CI -0.27 to -0.01]; p = 0.02), but did not significantly decrease fat mass, insulin, low-densitiy lipoprotein, high-density lipoprotein, or blood pressure as compared with CON. Furthermore, IF decreased body weight (WMD -1.14 kg [95% CI -1.69 to -0.60]; p = 0.001) and BMI (WMD -0.43 kg.m2 [95% CI -0.58 to -0.27]; p = 0.001), but did not significantly affect fat mass, lean body mass, visceral fat, insulin, HbA1c, lipid profiles or blood pressure. CONCLUSION: Intermittent fasting is effective for weight loss and specific cardiometabolic health markers in individuals with prediabetes or T2D. Additionally, IF is associated with a reduction in body weight and BMI compared to CR, without effects on glycaemic markers, lipid profiles or blood pressure.

RESUMEN

Little is known either about either physical activity patterns, or other lifestyle-related prevention measures in heart transplantation (HTx) recipients. The history of HTx started more than 50 years ago but there are still no guidelines or position papers highlighting the features of prevention and rehabilitation after HTx. The aims of this scientific statement are (i) to explain the importance of prevention and rehabilitation after HTx, and (ii) to promote the factors (modifiable/non-modifiable) that should be addressed after HTx to improve patients' physical capacity, quality of life and survival. All HTx team members have their role to play in the care of these patients and multidisciplinary prevention and rehabilitation programmes designed for transplant recipients. HTx recipients are clearly not healthy disease-free subjects yet they also significantly differ from heart failure patients or those who are supported with mechanical circulatory support. Therefore, prevention and rehabilitation after HTx both need to be specifically tailored to this patient population and be multidisciplinary in nature. Prevention and rehabilitation programmes should be initiated early after HTx and continued during the entire post-transplant journey. This clinical consensus statement focuses on the importance and the characteristics of prevention and rehabilitation designed for HTx recipients.

RESUMEN

This report presents a 57-year-old female with a history of dyslipidaemia, intolerant to statins and currently managed on evolocumab. Despite a healthy lifestyle, lipid panel abnormalities persisted, leading to an investigation that revealed heterozygous mutations in the ABCG8 gene, confirming a diagnosis of sitosterolaemia. The patient's unique response to lipid-lowering medications typified this rare disorder, necessitating specialised genetic testing for diagnosis. Management involved dietary modifications and the introduction of ezetimibe, evolocumab and atorvastatin, demonstrating the personalised nature of treatment. The case underscores the importance of considering sitosterolaemia in unexplained lipid abnormalities and highlights the challenges in diagnosis and management. Ongoing research is crucial for refining diagnostic and therapeutic strategies for this clinically significant disorder, emphasising the need for a multidisciplinary approach to patient care. LEARNING POINTS: Recognise the significance of considering sitosterolaemia in differential diagnosis for unexplained lipid abnormalities.Understand the challenges in diagnosing and managing sitosterolaemia, especially in patients with atypical responses to conventional lipid-lowering therapies.

RESUMEN

Dyslipidaemia is a complex disorder characterised by abnormal lipid levels in the blood, including cholesterol and triglycerides, and plays an important role in the development of atherosclerotic cardiovascular disease. Most risk factors for cardiovascular disease are modifiable, and dyslipidaemia is a key factor among them. It can result from a combination of genetic and environmental factors. A distinction is made between primary dyslipidaemia, which is mainly caused by inherited genetic changes, and secondary dyslipidaemia, which is due to underlying diseases or certain medications. The treatment of dyslipidaemia has evolved over the years. In the past, statins were the first choice, but newer drugs, such as proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, have gained prominence due to their effectiveness in lowering lipids. Although recent guidelines recommend PCSK9 inhibitors for high-risk patients and patients who cannot tolerate statins, their widespread use is limited because of cost. Several meta-analyses have confirmed the efficacy and safety of PCSK9 inhibitors and have shown a significant reduction in low-density lipoprotein (LDL) cholesterol levels. However, the long-term side effects and interactions with other risk factors for cardiovascular disease remain uncertain. In addition, cost-effectiveness analyses have shown mixed results, with some countries considering PCSK9 inhibitors to be cost-effective for certain patient groups, while others consider them less economical. Meanwhile, initial data from patients using PCSK9 inhibitors support the results of the clinical trials. To summarise, PCSK9 inhibitors represent a revolutionary solution for lowering LDL cholesterol, but their cost-effectiveness remains controversial. Despite the controversy, they offer clear benefits for high-risk patients and should therefore be considered in the treatment of dyslipidaemia.

RESUMEN

Objective: To compare the efficacy of tocotrienol and tocopherol in the management of patients with atherosclerotic cardiovascular diseases. METHODS: The systematic review was conducted in line with Preferred Reporting Items for Systematic Reviews and Meta- Analyses guidelines 2020, and comprised literature search from 2002 till January 5, 2023, on PubMed, Google Scholar, Cochrane Library, Google, Wiley-Inter Science Library, Medline, SpringerLink, Taylor and Francis databases. The search was conducted using key words, such as: "tocopherol", "tocotrienol", "vitamin E", "dyslipidaemia", "cardiovascular diseases" "cardioprotective", "hypercholesterolemia" and "atherosclerosis" along with Boolean operators. Human clinical studies regarding the use of tocotrienol or tocopherol or comparison of its efficacy in patients having atherosclerosis, dyslipidaemia leading to cardiovascular diseases, and studies including details of efficacy of any of the four alpha, beta, gamma, delta isomers of tocopherol or tocotrienol were included. Pertinent data from the eligible studies was retrieved and reviewed. RESULTS: Of the 516 articles identified, 26 (5%) articles met eligibility criteria. Of them 5(19%) were subjected to detailed analysis. Tocotrienol showed significant anti-oxidant efficacy at (250 mg/d) by decreasing cholesterol and serum inflammatory biomarkers i.e C-reactive protein (40%), malondialdehyde (34%), gamma-glutamyl transferase (22%) (p<0.001). Total anti-oxidant status (TAS) levels raised 22% (p<0.001) and Inflammatory cytokines i.e resistin, interleukin (IL)-1, IL-12, Interferon-gamma were decreased 15-17% (p<0.05-0.01) respectively by tocotrienol. Several microRNA (miRNA-133a, miRNA-223, miRNA-214, miRNA-155) were modulated by δ-tocotrienol. Whereas, tocopherol showed heterogeneity of results by either decreasing or increasing the risk of mortality in atherosclerotic cardiovascular diseases. Conclusion: Compared to tocopherol, tocotrienol was found to be safe and potential candidate for improving cardiovascular health in the management of atherosclerotic cardiovascular diseases.
