Effect of Acupuncture on Artery Elasticity for Atherosclerosis: A Randomized Controlled Trial

Background Atherosclerosis (AS) is a chronic arterial disease. Atherosclerosis related diseases, like myocardial infarctions (MI) and strokes have the highest mortality and disability rate. However, limited evidence verified the effects of acupuncture on arterial stiffness for subclinical atherosclerosis. We hypothesized that acupuncture could improve arterial stiffness in subclinical atherosclerosis and resist plaque progression. The aim of this study is to assess the effect of acupuncture on arterial elasticity via ultrafast pulse wave velocity (ufPWV) and explore the effect of acupuncture on lipid level and platelet function for subclinical atherosclerosis patients.MethodsThis was a randomized parallel controlled trial included 44 patients. Patients were assigned in a 1:1 ratio to acupuncture group and sham acupuncture group. Patients completed 24 treatments in total within 12 weeks of intervention. The primary outcome was ultrafast pulse wave velocity (ufPWV) assessed after every 4-weeks treatment; the secondary outcomes were carotid intima-media thickness (cIMT), blood lipid levels, fibrinogen (FIB) and blood platelet. Intention-to-treat (ITT) principle was applied and data sets were analyzed using SPSS 20.0 software.ResultsAmong the 44 randomly assigned patients, changes of right-side BS value in TA group (0.841) at week 12 were greater than SA group (-0.189), with a mean difference of 1.030 (95% CI, 0.320, 1.739; P=0.006). Similar results were observed in right-side ES, left-side BS, left-side ES at week 12. As to secondary outcomes, compared with SA group(1.08mm), the TA group(0.98mm) showed a significant decline in mean of left-side IMT at week 12. (Z= -2.118; P=0.034). There were no serious adverse events.ConclusionsAmong patients with Carotid intima-media thickening, both-side carotids arterial elasticity is significantly improved after 12-week acupuncture compared with sham acupuncture. The effects of acupuncture are more noticeable at week 12 during end-systole.Trial registrationThe trial was registered at http://www.chictr.org.cn (NO. ChiCTR1900025551, 31/08/2019)

Level of advanced oxidation protein products is associated with subclinical atherosclerosis

Background Oxidative stress is an important factor in the pathomechanism of atherosclerosis. Advanced oxidation protein products (AOPPs) are considered markers of oxidative stress. Thickening of the carotid intima-media layers indicates subclinical atherosclerosis and can be detected by carotid ultrasound. Objective Our aim was to examine the association between carotid intima-media thickness (CIMT) and the level of AOPPs. Methods Carotid duplex scans and measurements of AOPPs were performed on 476 participants of a cardiovascular population study. The presence of conventional cardiovascular risk factors was investigated with a questionnaire, physical examination, and laboratory tests. Results There was a positive correlation between maximum CIMT and the level of AOPPs only in the male population (r = 0.219, p = 0.033). Multivariate analysis has revealed that the association between AOPPs and mean or maximum CIMT was independent of cardiovascular risk factors (OR = 1.458, p = 0.004, and OR = 2.038, p < 0.001). Conclusions Among males, the elevated level of AOPPs as a marker of oxidative stress may signal the existence of early atherosclerotic alterations.

Pathophysiology of Mild Hypercortisolism: From the Bench to the Bedside

Mild hypercortisolism is defined as biochemical evidence of abnormal cortisol secretion without the classical detectable manifestations of overt Cushing’s syndrome and, above all, lacking catabolic characteristics such as central muscle weakness, adipose tissue redistribution, skin fragility and unusual infections. Mild hypercortisolism is frequently discovered in patients with adrenal incidentalomas, with a prevalence ranging between 5 and 50%. This high variability is mainly due to the different criteria used for defining this condition. This subtle cortisol excess has also been described in patients with incidentally discovered pituitary tumors with an estimated prevalence of 5%. To date, the mechanisms responsible for the pathogenesis of mild hypercortisolism of pituitary origin are still not well clarified. At variance, recent advances have been made in understanding the genetic background of bilateral and unilateral adrenal adenomas causing mild hypercortisolism. Some recent data suggest that the clinical effects of glucocorticoid (GC) exposure on peripheral tissues are determined not only by the amount of the adrenal GC production but also by the peripheral GC metabolism and by the GC sensitivity. Indeed, in subjects with normal cortisol secretion, the combined estimate of cortisol secretion, cortisone-to-cortisol peripheral activation by the 11 beta-hydroxysteroid dehydrogenase enzyme and GC receptor sensitizing variants have been suggested to be associated with the presence of hypertension, diabetes and bone fragility, which are three well-known consequences of hypercortisolism. This review focuses on the pathophysiologic mechanism underlying both the different sources of mild hypercortisolism and their clinical consequences (bone fragility, arterial hypertension, subclinical atherosclerosis, cardiovascular remodeling, dyslipidemia, glucose metabolism impairment, visceral adiposity, infections, muscle damage, mood disorders and coagulation).

Postprandial Hyperlipidemia: Association with Inflammation and Subclinical Atherosclerosis in Patients with Rheumatoid Arthritis

Objective: To describe postprandial lipidemia in patients with rheumatoid arthritis (RA) and to analyze its association with subclinical atherosclerosis and inflammatory activity. Methods: Observational study of 80 cases of RA and 80 sex- and age-matched controls. We excluded individuals with dyslipidemia. Postprandial hyperlipidemia (PPHL) was defined as postprandial triglycerides >220 mg/dL and/or postprandial ApoB48 levels >75th percentile (>p75). Plasma lipids, cholesterol, triglycerides, ApoB48, and total ApoB were evaluated at baseline and after a meal. Other variables analyzed included subclinical atherosclerosis (defined as presence of carotid atheromatous plaque), inflammatory activity (disease activity score (DAS28-ESR)), cytokines, apolipoproteins, and physical activity. A multivariate analysis was performed to identify factors associated with PPHL in patients with RA. Results: A total of 75 patients with RA and 67 healthy controls fulfilled the inclusion criteria. PPHL was more frequent in patients with RA than controls (No. (%), 29 (38.70) vs. 15 (22.40); p = 0.036), as was subclinical atherosclerosis (No. (%), 22 (30.10) vs. 10 (14.90); p = 0.032). PPHL in patients with RA was associated with subclinical atherosclerosis (OR (95% CI) 4.69 (1.09–12.11); p = 0.037), TNF-α (OR (95% CI) 2.00 (1.00–3.98); p = 0.048), high-sensitivity C-reactive protein (OR (95% CI) 1.10 (1.01–1.19); p = 0.027), and baseline triglycerides (OR (95% CI) 1.02 (1.00–1.04); p = 0.049). Conclusion: PPHL was more frequent in patients with RA than in controls. PPHL in patients with RA was associated with inflammation and subclinical atherosclerosis.

Association between Insomnia and Subclinical Atherosclerosis Among Chinese Steelworkers: A Cross-sectional Survey

Background: Insomnia is a common prevalent sleep disorder. Difficulty maintaining sleep or poor in quality in insomnia caused by disrupted or misaligned circadian rhythms may play an important role in the development of atherosclerosis. This study aimed to examine the association between insomnia and subclinical atherosclerosis in Chinese steelworkers.Methods: A total of 3582 subjects from a large enterprise located in northern China were included in this study. The Athens Insomnia Scale (AIS) was used to assess the status of insomnia. Subclinical atherosclerosis was evaluated using ultrasonographic measurements of carotid plaque. Multivariable logistic regression was used to identify association between insomnia and carotid atherosclerosis.Results: The overall prevalence of insomnia and carotid plaque were 35.1% and 29.9% in the study population. Compared with non-insomnia workers, significantly increased odds of carotid plaque were observed among insomnia workers after adjustment for potential confounders, odds ratio (OR) = 1.38, 95% confidence interval (CI): 1.17 to 1.62. Exposure to current shift work and insomnia simultaneously can significantly elevated odds of carotid plaque. No significant association was found in female workers between insomnia and carotid plaque.Conclusion: Insomnia is associated with elevated odds of carotid atherosclerosis in male steelworkers. Insomnia problems of workers should receive further attention in occupational worker health interventions.

The effect of therapy on subclinical atherosclerosis of the carotid arteries in patients with calcium pyrophosphate crystal deposition disease and osteoarthritis (pilot study)

Endothelial dysfunction associated with chronic microcrystalline inflammation plays a role in the progression of atherosclerosis in calcium pyrophosphate crystal deposition diseases (CPPD).The aim of the study was to assess the dynamics of the development of atherosclerosis based on changes in the thickness of the intima-media complex (ICIM) of the carotid arteries (CA) in patients with CPPD receiving long-term anti-inflammatory therapy (colchicine, methotrexate, hydroxychloroquine).Materials and methods. 26 patients with CPPD and 26 patients with osteoarthritis aged over 18 years old were included. Exclusion criteria: age >65 years; presence of cardiovascular diseases. The blood lipid spectrum, hs-CRP level, anthropometric parameters were determined for all, and Doppler ultrasound ultrasonography of the carotid arteries (CA) was performed. Patients were followed up for not <6 months, assessed ICIM CA at 1 visit, then patients with CPPD, at the discretion of the attending physician, were prescribed methotrexate at a dose of 15 mg per week, hydroxychloroquine 200 mg 1 time per day or colchicine 0.5 mg 2 times a day. Patients could take NSAIDs if they were in pain. The SCORE index has been calculated for everyone.Results. Initially, ICIM values did not differ in patients with CPPD and OA. Initially, ICIM>0.9 mm were detected in 11 of 22 (50%) patients with CPPD and in OA in 8 of 19 (42%) (p=0.39). In dynamics, patients with CPPD revealed a decrease in the number of patients with ICIM>0.9 mm from 42 to 18%. At the same time, in 8 patients with CPPD, ICIM>0.9 mm was combined with a CRP level >0.2 mg/l. Out of 22 patients with CPPD, 14 (64%) patients showed a decrease in the mean values of ICIM, in 2 (9%) patients - an increase, in 5 patients the mean values of ICIM did not change. After 6 months of therapy, out of 11 patients with CPPD with ICIM >0.9 mm, after 6 months of therapy, in 7 cases there was a decrease in the indicator less than the specified value, in 5 of them a decrease in serum CRP level <2 mg/l was recorded. In patients with CPPD, the serum CRP level significantly decreased; in patients with OA, it did not change. Out of 19 patients with OA, 9 (47%) patients showed an increase in the mean ICIM over time, while the rest did not change. In those treated with hydroxychloroquine, a decrease in the mean ICIM parameters was observed in 5 out of 6 (83%) patients, colchicine - in 6 out of 9 (67%) patients, methotrexate - in 4 out of 7 (57%) patients.With CPPD, the result of therapy with colchicine, methotrexate and hydroxychloroquine in relation to the development of the initial signs of atherosclerosis according to Doppler ultrasound ultrasonography of CA can be realized based on the presence of chronic inflammation.

Association between Non-HDL-C/HDL-C Ratio and Carotid Intima–Media Thickness in Post-Menopausal Women

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.

Cardiovascular Risk Factors and Subclinical Atherosclerosis in Greek Adolescents with Polycystic Ovary Syndrome: Its Relationship with Body Mass Index

Polycystic ovary syndrome (PCOS) is the most common endocrine condition affecting 6–18% of adolescents and is strongly associated with obesity and cardiovascular risk factors, enhancing the risk of atherosclerosis. Thirty-two adolescents with newly diagnosed PCOS were evaluated for lipid profile disorders, insulin resistance, inflammation, non-alcoholic fatty liver disease (NAFLD), and subclinical atherosclerosis through measurements of carotid intima–media thickness (cIMT). The relationships of the above markers with increased body mass index and abdominal obesity were investigated. Twenty-three adolescents (72%) were overweight (OW) or obese (OB). The OW/OB group had significantly higher insulin, HOMA-IR, high-sensitive C-reactive protein (hsCRP), visceral adiposity index (VAI), and lipid accumulation product (LAP) levels; and lower glucose-per-insulin ratios and HDL-C levels compared to the healthy weight group. The cIMT and small dense low-density lipoprotein cholesterol (sdLDL-C) levels did not differ between the two groups. Similarly, cIMT and sdLDL-C levels did not differ between PCOS-adolescents and healthy controls. CIMT was positively correlated with systolic blood pressure and waist circumference per height ratio. In conclusion, OW/OB PCOS-adolescents have a cluster of adverse factors predisposing them to atherosclerotic cardiovascular disease. Therefore, early cardiovascular risk assessment, as well as timely and targeted interventions, are necessary for prevention.
