“…However, early meta-analyses have not found conclusive evidence to support cIMT as an independent predictor of future cardiovascular events (18, 19). The variations observed among different studies in terms of their findings may be attributed to the lack of precision and reproducibility in early ultrasound examination techniques (20).…”

PurposeAn elevated concentration of phosphorus is associated with an increased risk of atherosclerosis and cardiovascular diseases. Common carotid artery intima–media thickness (cIMT) is an imaging marker of atherosclerosis. However, data on the relationship between phosphorus and cIMT in ischemic stroke are scarce. We aimed to evaluate the association between serum phosphorus levels and cIMT in patients who had experienced ischemic stroke.Patients and methodsA total of 1,450 ischemic stroke patients were enrolled. Participants were divided into four groups (quartiles) according to baseline serum phosphorus level. Carotid atherosclerosis was identified by measurement of cIMT; abnormal cIMT was defined as a maximum cIMT or mean cIMT ≥ 1 mm. Multivariable logistic regression models were used to assess the association between serum phosphorus level and the presence of abnormal cIMT.ResultsIn the multivariable adjusted analysis, falling into the highest quartile for serum phosphorus (Q4) was associated with a 2.00-fold increased risk of having abnormal maximum cIMT [adjusted odds ratio (OR) 2.00; 95% confidence interval (CI) 1.44–2.79] and a 1.76-fold increased risk of having abnormal mean cIMT (adjusted OR 1.76; 95% CI 1.22–2.53) in comparison to Q1. Furthermore, the association between serum phosphorus and abnormal cIMT was confirmed in analyses treating serum phosphorus as a continuous variable and in subgroup analyses.ConclusionIn acute ischemic stroke patients, baseline elevated serum phosphorus level was found to be independently associated with carotid atherosclerosis, as measured by cIMT.

“…Measurements of the CIMT (maximum and mean of left and right CIMT) were carried out in the patients at the 2-cm distance of the common carotid bifurcation[1819] at baseline and after the 12-week treatment using a Doppler ultrasonography device (Samsung Medison V20, Korea) with linear multifrequencies of 7.5-to 10-MHz probe. All CIMT (mean and maximum thickness) measurements were evaluated blindly by a single experienced ultrasonographer.…”

Background: This study was performed to evaluate the effects of carnitine administration on carotid intima-media thickness (CIMT) and inflammatory markers in women with polycystic ovary syndrome (PCOS). Methods: This randomized, double-blind, placebo-controlled trial was conducted among 60 women diagnosed with PCOS according to the Rotterdam criteria, aged 18–40 years. Participants were randomly allocated into two groups to intake either 250 mg/day carnitine ( n = 30) or placebo ( n = 30) for 12 weeks. High-resolution carotid ultrasonography was conducted at baseline and after the 12-week intervention. Results: After the 12-week intervention, compared with the placebo, carnitine supplementation resulted in a significant decrease in maximum levels of the left CIMT (−0.01 ± 0.02 vs. +0.002 mm ± 0.006 mm, P = 0.001), mean levels of the left CIMT (−0.01 ± 0.02 vs. +0.001 mm ± 0.01 mm, P = 0.001), maximum levels of the right CIMT (−0.01 ± 0.02 vs. +0.006 mm ± 0.01 mm, P < 0.001), and mean levels of the right CIMT (−0.01 ± 0.02 vs. +0.002 mm ± 0.01 mm, P = 0.001). Change in plasma nitric oxide (NO) (+2.4 ± 3.6 vs. +0.2 ± 2.3 μmol/L, P = 0.007) was significantly different between the supplemented patients and placebo group. We did not see any significant effect in serum high sensitivity C-reactive protein (hs-CRP) following the supplementation of carnitine compared with the placebo. Conclusions: Overall, carnitine administration for 12 weeks to participants with PCOS had beneficial effects on CIMT and plasma NO, but did not affect serum hs-CRP levels.

The aim. To analyze the frequency of atherosclerotic lesions of the carotid arteries and association with the lipid metabolism and inflammatory markers in hypertensive patients with gout. Materials and methods. 122 patients with hypertension aged 30 to 65 years were examined (mean age (56.0 (47.0; 62.0)), including 104 men (85.2 %) and 18 women (14.8 %). Group 1 included 72 hypertensive patients with gout; group 2 – 50 hypertensive patients without gout; group 3 – 20 gout patients without hypertension. Serum levels of high sensitivity C-reactive protein were detected by enzyme-linked immunosorbent assay. Serum ferritin levels were measured using electrochemiluminescent detection. The patients underwent carotid artery ultrasound according to standard methods. Results. The duration of gout exacerbation and the pain intensity evaluated with the visual analog scale (VAS) (P < 0.01) were significantly higher in group 1, than those in group 3 (P < 0.01). Serum ferritin levels were 2.6 (P < 0.01) times higher in group 1 than those in group 2. In patients with gout, the levels of ferritin were significantly 2.1 times higher, than in group 2 (P < 0.01). The levels of hsСRP in patients of group 1 were 3.1 times higher than those in group 2 (P < 0.01). The proportion of patients with intima-media complex (IMC) thickness ≥0.9 mm was higher in group 1 than in groups 2 (χ2 = 4.58, P < 0.05) and 3 (χ2 = 24.96, P < 0.01). In the structure of plaques, isoechoic were significantly more often seen among group 1 patients as compared to group 3 (χ2 = 6.56, P < 0.01), and hyperechoic – as compared to group 2 (χ2 = 4.63, P < 0.05). Hypoechoic plaques were detected in groups 1 and 2 with similar frequency (P > 0.05). This type of plaque was associated with a high risk of cerebrovascular events. In the patients with arterial hypertension and gout, a significant moderate positive correlation was found between the IMC thickness and the serum uric acid level (rs = 0.46, P < 0.01), hsCRP (rs = 0.33, P < 0.01), age (rs = 0.33; P < 0.01), duration of gout (rs = 0.27, P < 0.05) and VAS (rs = 0.39, P < 0.01); the level of hsCRP was correlated with the presence of atherosclerotic plaques (τ = +0.64, P < 0.05). Conclusions. The combination of hypertension with gout in patients was associated with a high incidence of IMC thickness ≥0.9 mm and atherosclerotic plaques, more severe disorders of purine and lipid metabolism, increased inflammatory markers (ferritin and hsCRP), that should be considered not only in the aspect of chronic inflammation, but also as a part of the disease.
