ABSTRACT
ABSTRACT Introduction: Patients with β-thalassemia major (β-TM) are at risk of developing abnormal lipid profiles. Lipid abnormalities, in turn, have a potential role in the pathogenesis of some clinical aspects of thalassemia Objectives: To evaluate lipid levels and atherogenic indices in β-TM patients compared to healthy children and for any association between lipid levels, lipid peroxidation and inflammatory biomarkers Methods: This case-control study was carried out on 79 patients with β-TM, aged 6 to 16 years, registered at the Basrah Center for Hereditary Blood Diseases and 85 age- and sex-matched apparently healthy children and adolescents. Complete blood count, serum lipids and ferritin, liver function tests, C-reactive protein (CRP), high-sensitivity CRP (hs-CRP) and serum malondialdehyde (MDA) were evaluated Results: Patients with β-TM had significantly lower hemoglobin (Hb), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and non-high-density lipoprotein (non-HDL) and significantly higher very low-density lipoprotein (VLDL), triglycerides (TGs), LDL/HDL ratio, MDA, hs-CRP, total serum bilirubin (TSB), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) than the control group (p < 0.05). A bivariate analysis revealed that TC has a significant positive association with Hb. The TG has a significant negative association with Hb and a positive association with serum ferritin. Furthermore, MDA, TG, TSB, ALT and AST were significantly positively correlated with serum ferritin (p < 0.05) Conclusions: Atherogenic dyslipidemia, defined as a high low-density lipoprotein cholesterol (LDL-C/high-density lipoprotein cholesterol (HDL-C) ratio and high TG level, is common among pediatric β-TM patients, it is associated with iron overload and places patients at an increased cardiovascular risk.
ABSTRACT
Objectives: Exposure of aluminium (Al) to mankind is inescapable, and its dyslipidaemic impact is a possible contributing factor to health hazards like cardiovascular diseases. The health effects due to the metalloestrogenic property of the metal need imperative consideration. The current experimental work was undertaken to explore Al-induced dyslipidaemia due to its metalloestrogenic property. Materials and Methods: To fulfil this objective, prepubertal (PP) and young adult (YA) female Wistar rats were intraperitoneally administered to two doses of Al [5 and 10 mg/Kg body weight (BW)] once daily for 2 weeks. After the completion of the acute exposure protocol, plasma and hepatic tissue lipid profiles were estimated. Analysis of variance was carried out by the Kruskal–Wallis test and the differences between the groups were analysed by Mann–Whitney U post hoc test Results: Increased triglyceride, total cholesterol, low-density lipoprotein (LDL) cholesterol and very-LDL cholesterol in plasma were found in YAs treated with both doses of Al in a dose-dependent manner. Similar changes were not present in PP female rats. Decreased levels of lipid levels were observed in the case of hepatic lipid profile. Conclusion: The study ushers light towards the dyslipidaemic alterations in experimental female rats after acute Al exposure. Impacts of Al on the growth and organosomatic index during the vital developmental days were significantly decided by the pubertal status of the female rats. The results of this study indicate the impact of puberty on the Al-induced modifications in lipid profile parameters and cardiovascular risk factors.
ABSTRACT
OBJECTIVES@#To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma.@*METHODS@#This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis.@*RESULTS@#The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686).@*CONCLUSIONS@#AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.

Objective:To explore the correlation between serum uric acid level and atherogenic index of plama (AIP) in patients with type 2 diabetes mellitus (T2DM).Methods:A retrospective analysis of 485 T2DM patients hospitalized in the First Hospital of Qin Huangdao was performed in August 2019 to August 2021. They were divided into atherogenic phenotype group (the case group, AIP≥0.06, n=326) and non atherogenic phenotype group (the control group, AIP<0.06, n=159) with AIP=0.06 as the cut-off point. The age, sex, body mass index, uric acid, triglyceride, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, glycosylated hemoglobin, smoking history and coronary heart disease history were compared between the two groups. The data processing using sample t-test and chi-square test. Pearson correlation analysis and multivariate logistic regression analysis were performed. Results:Body mass index (27.7±3.6) kg/m 2, systolic pressure (138.4±17.5) mmHg, uric acid (351.6±93.0) μmol/L, triglyceride (3.0±3.4) mmol/L and the proportion of men (61.6%(201/326)), coronary heart disease history (24.3%(79/326)) and smoking history (33.5%(109/326)) in case group were higher than those in control group (25.8±3.5) kg/m 2, (132.2±17.7) mmHg, (291.6±73.8) μmol/L, (1.0±0.3) mmol/L, (51.6%(82/159)), (15.7%(25/159)), (19.5%(31/159)) and the level of high density lipoprotein-cholesterol (1.1±0.3) mmol/L was lower than that in control group (1.3±0.3) mmol/L,with all statistically significant differences ( t=5.43, P<0.001; t=3.64, P<0.001; t=7.70, P=0.001; t=10.40, P<0.001; χ 2=4.47, P=0.034;χ 2=4.60, P=0.032;χ 2=10.11, P=0.001; t=5.18, P<0.001). The prevalence of hyperuricemia in case group (21.5%(70/326)) was 4.3 times higher than that in control group (5.0%(8/159)). AIP was positively correlated with body mass index ( r=0.300, P<0.001), uric acid ( r=0.343, P<0.001), systolic pressure ( r=0.117, P=0.010), diastolic pressure (r=0.119, P=0.009), triglyceride ( r=0.724, P<0.001), total cholesterol ( r=0.226, P<0.001), while that was negatively correlated with high density lipoprotein-cholesterol ( r=-0.185, P<0.001). Logistic regression analysis showed that after excluding the interference of other factors, uric acid was still related to AIP ( OR=3.727, 95% CI=1.702-8.158, P=0.001), and the risk of AIP increase increased with the increase of uric acid level. Conclusion:The level of serum uric acid in T2DM patients is related to AIP, and high uric acid is an independent risk factor for AIP in T2DM patients.
ABSTRACT
Objective:To investigate the predictive value of atherogenic index of plasma (AIP) in the assessment of acute pancreatitis (AP).Methods:598 patients diagnosed with AP admitted to the Affiliated Hospital of Yangzhou University between January 2016 and December 2020 were recruited and divided into severe acute pancreatitis group (SAP group, n=57) and non-severe acute pancreatitis group (non SAP group, n=541) according to the Atlanta Classification (2012 revision). General clinical data and related biochemical indicators of all enrolled patients were collected, and Bedside Index of Acute Pancreatitis Severity (BISAP) score, Ranson score and CT Severity Index (CTSI) score were performed. The risk factors of SAP were analyzed by logistic regression. Receiver operating characteristic (ROC) curve was used to analyze the evaluation value of AIP and various scoring systems on the severity of pancreatitis. Results:The AIP, white blood cell (WBC), neutrophil count (NEUT), fasting blood glucose (FBG), serum total cholesterol (TC) level, proportion of hyperlipidemia, proportion of diabetes, Ranson score, BISAP score, CTSI score of patients in SAP group were higher than those in non SAP group, and the difference was statistically significant (all P<0.05). Multivariate logistic regression analysis showed that AIP was an independent risk factor for SAP ( P<0.05). ROC curve showed that the are under the curve (AUC) of SAP predicted by AIP was 0.706(95% CI: 0.631-0.782, P<0.001). Conclusions:AIP is an independent risk factor for SAP, which helps to assess the severity of AP.
ABSTRACT
Objective To investigate the correlation between atherogenic index of plasma (AIP) and the severity of hypertriglyceridemic acute pancreatitis (HTG-AP) and the value of AIP combined with Bedside Index for Severity in Acute Pancreatitis (BISAP) score in the early prediction of severe HTG-AP (sHTG-AP). Methods A retrospective analysis was performed for the clinical data of 170 patients with HTG-AP who were hospitalized in The General Hospital of Central Theater Command from January 2017 to December 2021, and according to related guidelines, they were divided into the sHTG-AP group with 28 patients and non-sHTG-AP group with 142 patients. Peripheral blood samples were collected from all patients within 24 hours after admission, and the two groups were compared in terms of sex, age, laboratory test results, AIP, BISAP score, and modified CT severity index (MCTSI) score. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups; the Mann-Whitney U test was used for comparison of continuous data between groups. The Spearman rank correlation test was used to investigate the correlation between each factor and the severity of HTG-AP, and the binary logistic regression analysis were used to investigate the independent risk factors for sHTG-AP. The receiver operating characteristic (ROC) curve was plotted to assess the predictive efficacy of each indicator. Results There were significant differences between the two groups in the medical history of diabetes, lymphocyte count, albumin, Ca 2+ , triglyceride, high-density lipoprotein cholesterol, AIP, BISAP score, MCTSI score, length of hospital stay, and hospital costs (all P < 0.05). The sHTG-AP group had a longer length of hospital stay, higher hospital costs, and a higher AIP value. AIP (odds ratio [ OR ]=1.244, 95% confidence interval [ CI ]: 1.062-1.458, P =0.007), BISAP score ( OR =5.525, 95% CI : 1.646-18.543, P =0.006), and MCTSI score ( OR =2.029, 95% CI : 1.245-3.305, P =0.004) were risk factors for sHTG-AP. AIP, BISAP score, and MCTSI score were positively correlated with the severity of HTG-AP ( r =0.291, 0.631, and 0.649, all P < 0.001), and AIP was positively correlated with BISAP score and MCTSI score ( r =0.190 and 0.215, both P < 0.05). AIP had an optimal cut-off value of 1.095 in predicting sHTG-AP, and AIP, BISAP score, and AIP combined with BISAP score had an area under the ROC curve of 0.759, 0.887, 0.925, respectively, a sensitivity of 0.821, 0.857, and 0.786, respectively, and a specificity of 0.627, 0.817, and 0.937, respectively (all P < 0.001). Conclusion AIP is a risk factor for sHTG-AP and is correlated with disease severity, and AIP combined with BISAP score has a relatively high value in the early prediction of sHTG-AP.
ABSTRACT
Objective To investigate the association between atherogenic index of plasma (AIP) and metabolic associated fatty liver (MAFLD) in type 2 diabetes mellitus (T2DM). Methods A total of 375 patients with T2DM who were hospitalized and treated in Department of Endocrinology, The First Affiliated Hospital of Zhengzhou University, from September 2021 to September 2022 were enrolled, and according to the presence or absence of MAFLD, they were divided into T2DM+MAFLD group with 245 patients and T2DM group with 130 patients. Related clinical data were recorded, and AIP was calculated. According to the quartiles of AIP, the patients were divided into Q1 group (AIP≤0.20), Q2 group (0.20 0.48). The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between groups; the trend chi-square test was used for the trend analysis of categorical data. The multivariate logistic regression analysis was used to investigate the effect of AIP on MAFLD, and the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) were used to assess the value of the indicators such as AIP, body mass index (BMI), and alanine aminotransferase (ALT) in predicting T2DM with MAFLD. Results Compared with the T2DM group, the T2DM+MAFLD group had significant increases in BMI, systolic pressure, uric acid, fasting blood glucose, glycosylated hemoglobin, ALT, aspartate aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase, triglyceride, low-density lipoprotein, and AIP and a significant reduction in high-density lipoprotein (all P < 0.05). The trend chi-square test showed that the prevalence rate of MAFLD in T2DM patients tended to increase with the increase in AIP level ( χ trend 2 =20.338, P < 0.05). The multivariate logistic regression analysis showed that compared with the Q1 group, the Q4 group had a significant increase in the risk of MAFLD (odds ratio =2.396, 95% confidence interval: 1.018-5.640, P =0.045). The ROC curve analysis showed that the diagnostic model of AIP combined with BMI and ALT had the best diagnostic performance (AUC=0.816), with a sensitivity of 70.2% and a specificity of 78.5% at the optimal cut-off value of 0.670. Conclusion AIP is an independent risk factor for MAFLD in T2DM patients, and AIP combined with BMI and ALT has a good predictive value for T2DM with MAFLD.
ABSTRACT
Objective:The aims of the study were to investigate the relationship among atherogenic index of plasma (AIP) and inflammatory adipocytokines with the severity of coronary artery calcification (CAC) score in coronary artery disease (CAD). And then we analyzed the diagnostic value of the new markers on CAC.Methods:A total of 241 patients with CAD diagnosed by coronary CT angiography (CTA) and coronary angiography in Baoding First Central Hospital from June 2019 to June 2020 were retrospectively enrolled. According to the presence of calcification in coronary CTA, they were divided into CAC group ( n=63) and non-CAC group ( n=178). The clinical data of the patients were collected, and the levels of serum inflammatory factors were measured by enzyme-linked immunosorbent assay (ELISA). The correlation between CAC score and AIP and inflammatory cytokines was analyzed. The diagnostic value of AIP and inflammatory factors in the formation of CAC in patients with CAD. Results:The levels of AIP, serum osteoprotegerin (OPG) and oligomeric matrix protein (COMP) in CAC group were higher than those in non-CAC group, while the levels of serum fibroblast growth factor 21 (FGF21) were lower than those in non-CAC group, with statistically significant difference (all P<0.01). Correlation analysis showed that CAC score of CAD patients was positively correlated with AIP, OPG and COMP ( r=0.581, 0.451, 0.326, P<0.05), and negatively correlated with FGF21 ( r=-0.294, P<0.05). Receiver operating characteristic (ROC) curve analysis showed that AIP, OPG, COMP and FGF21 had diagnostic value for CAC in CAD patients (all P<0.05). AIP>0.387, OPG>5.150 ng/ml, FGF21>136.35 pg/ml, COMP>733.16 ng/ml were independent factors affecting the formation of CAC (all P<0.05). Conclusions:The increase of AIP and the change of inflammatory factors can be used as markers for the diagnosis of CAC formation in CAD patients.
ABSTRACT
Objective:To determine the predictive value of atherogenic index of plasma (AIP) on the long-term prognosis of patients with coronary artery disease (CAD).Methods:A total of 2 500 patients with coronary heart disease who underwent coronary angiography in Affiliated Hospital of Jining Medical University from May 2013 to November 2015 were retrospectively analyzed. According to the AIP value, the subjects were divided into low AIP group (AIP<0.06) and high AIP group (AIP≥0.06). The incidence of major adverse cardiovascular events (MACE) was compared between the two groups. Kaplan-meier method was used to evaluate the MACE-free survival rate, and multivariate Cox survival analysis was used to evaluate the independent predictors of MACE.Results:A total of 2 427 patients were followed up, with a follow-up rate of 97.08% and a median follow-up time of 4.29 years. There were 1 123 cases in the low AIP group and 1 304 cases in the high AIP group, among which 624 patients (25.7%) had MACE. The total incidence of MACE in the high AIP group was higher than that in the low AIP group ( HR=1.43, 95% CI: 1.22-1.68, P<0.01). Kaplan-meier curves showed that the MACE-free survival rate was significantly lower in the high AIP group ( P<0.01). After adjusting for multiple confounding factors, AIP was still associated with the prognosis of CHD patients. Increased AIP (≥0.06) was an independent predictor of MACE in CHD patients within 4 years ( HR=1.34, 95% CI: 1.14-1.58, P<0.01). Conclusions:AIP (≥0.06) was an independent predictor of MACE occurrence in patients with CAD within 4 years. AIP has a certain value in the long-term prognosis of patients with CAD.
ABSTRACT
Objective:By comparing the changes of metabolic parameters before and after laparoscopic sleeve gastectomy (LSG) in patients with type 2 diabetes mellitus (T2DM) and obesity, the insulin resistance index (HOMA-IR) and atherogenic index of plasma (AIP) were calculated to evaluate the effect of metabolic surgery on insulin resistance and atherosclerosis in patients with type 2 diabetes mellitus (T2DM) and obesity.Methods:LSG treatment were retrospectively analyzed in 54 patients with type 2 diabetes mellitus and obesity, detection of preoperative and postoperative 1 month, 6 month of fasting plasma glucose (FPG), fasting insulin (FINS), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), measuring blood pressure, body weight, calculating body mass index, and according to the steady state evaluation model and the formula for calculating HOMA-IR and AIP. Before and after surgery, paired t test was used, and Pearson correlation analysis and multiple stepwise regression analysis.Results:FPG, FINS, TG, HOMA-IR and AIP were (6.38±2.03) mmol/L and (5.36±1.33) mmol/L, (20.42±25.77) uU/mLand (11.22±3.62) uU/mL, (1.94±2.81) mmol/Land (1.70±2.33) mmol/L, (5.60±7.52) and (2.58±0.80), (0.15±0.27) and (0.08±0.25) ,which were significantly lower than those before surgery ( P<0.05) ,HDL-C was (1.04±0.20) mmol/L and (1.10±0.18) mmol/L at 1 and 6 months after operation, respectively, which was higher than that before operation ( P<0.05) .Preoperative correlation analysis showed that AIP was positively correlated with FPG, TG and HOMA-IR ( P<0.05), and negatively correlated with HDL-C ( P<0.05) .The results of multiple stepwise regression analysis showed that FPG, TG and HDL-C were independent influencing factors of AIP ( P<0.05) . Conclusion:LSG surgery can effectively reduce the blood glucose and lipid levels in patients with type 2 diabetes complicated with obesity, improve insulin resistance and reduce the plasma atherosclerosis index.
ABSTRACT
RESUMEN Introducción: Acumulaciones excesivas de tejido adiposo constituyen una amenaza para la salud cardiometabólica, el estudio en la mujer orientaría mejor sobre su estado metabólico. Objetivo: Identificar asociaciones entre estados de vulnerabilidad cardiometabólica e índices aterogénicos en el posparto a corto plazo. Método: Se realizó un estudio observacional descriptivo, entre enero 2017 y agosto 2018, en 119 mujeres en el posparto a corto plazo, a partir de una población de 773 gestantes de peso adecuado y aparentemente sanas al momento de la captación, clasificadas por su vulnerabilidad cardiometabólica por adiposidad corporal en el Policlínico Chiqui Gómez Lubián, entre enero 2012 y diciembre 2016. Se estudió la asociación de la vulnerabilidad cardiometabólica con los índices aterogénicos: Castelli, Kannel y la relación TG/HDLc. Se aplicó la prueba de Kruskal-Wallis para la comparación de muestras independientes. Resultados: Los índices Castelli (3,37), Kannel (2,02) y TG/HDLc (0,71) tuvieron valores medios más bajos en las mujeres sin vulnerabilidad. Los índices Castelli (4,20) y Kannel (2,69) mostraron valores más elevados en mujeres con vulnerabilidad global extrema por adiposidad general alta y central alta. El índice TG/HDLc (1,18) tuvo los valores más elevados en mujeres con vulnerabilidad global por adiposidad general intermedia y central alta. Conclusiones: Los valores de los índices aterogénicos estudiados en el posparto a corto plazo estuvieron asociados con la vulnerabilidad cardiometabólica, con cifras más elevadas en mujeres con adiposidad general intermedia y alta, y adiposidad central alta. La vulnerabilidad cardiometabólica por adiposidad corporal en el posparto a corto plazo, puede alertar sobre alteraciones metabólicas aterogénicas, como riesgo cardiovascular.
ABSTRACT Introduction: Excessive accumulations of adipose tissue are a threat to cardiometabolic health; their assessment in women would better inform about their metabolic state. Objective: To identify associations between cardiometabolic vulnerability states and atherogenic indices in the short-term postpartum period. Method: A descriptive observational study was conducted from January 2017 to August 2018 on 119 women in short-term postpartum. The study population consisted of 773 pregnant women with adequate weight and apparently healthy at the time of recruitment, who were classified based on their cardiometabolic vulnerability due to body adiposity at the Policlínico Chiqui Gómez Lubián, between January 2012 and December 2016. The association of cardiometabolic vulnerability with the atherogenic indices was studied: Castelli, Kannel and the TG/HDLc ratio. The Kruskal-Wallis test was applied to compare independent samples. Results: The Castelli (3.37), Kannel (2.02) and TG/HDL (0.71) indices showed lower mean values in women without vulnerability. The Castelli (4.20) and Kannel (2.69) indices showed higher values in women with extreme global vulnerability due to high overall adiposity and high central adiposity. The TG/HDLc index (1.18) reached the highest values in women with global vulnerability due to intermediate and high central overall adiposity. Conclusions: The values of the atherogenic indices studied in the short-term postpartum period were associated with cardiometabolic vulnerability, with higher figures in women with intermediate and high general adiposity, and high central adiposity. Cardiometabolic vulnerability due to body adiposity in the short-term postpartum period may alert about atherogenic metabolic disorders, such as cardiovascular risk.
ABSTRACT
Objective:To investigate the correlation between multiple parameters of islet function evaluation and atherogenic index (AIP) in patients with type 2 diabetes mellitus (T2DM).Methods:A cross-sectional study was conducted to observe 216 T2DM patients hospitalized in Tianjin Medical University Chu Hsien-I Memorial Hospital in 2019. They were divided into non atherogenic phenotype group (N Group, AIP<0.06) and atherogenic phenotype group (A group, AIP≥0.06) with AIP=0.06 as the cut-off point. The general clinical indexes and evaluation indexes of oral glucose tolerance test (OGTT), such as insulin action index (IAI), quantitative insulin sensitivity check index (QUICKI), homeostasis model of insulin resistance index (HOMA-IR), homeostasis model assessment-β (HOMA-β), C peptide insulin resistance index (HOMA IR-CP) and C peptide islet function index suitable to diabetes patients (HOMA islet-CP DM) were compared between two groups. Pearson correlation analysis and multiple stepwise regression analysis were performed.Results:Compared with the N group, the very low density lipoprotein-cholesterol (VLDL-C), ln (HOMA IR-CP) and ln (HOMA islet-CP DM) in A group were higher ( P<0.01), while ln (QUICKI) was lower ( P<0.05), with statistical significance. AIP was positively correlated with VLDL-C ( r=0.765), ln (HOMA-IR) ( r=0.257), ln (HOMA-β) ( r=0.189), ln (HOMA IR-CP) ( r=0.418) and ln (HOMA islet-CP DM) ( r=0.377, P<0.01), and negatively correlated with IAI ( r=-0.145, P<0.05) and ln (QUICKI) ( r=-0.254, P<0.01). Multiple stepwise regression analysis showed that VLDL-C and ln (HOMA IR-CP) were independent influencing factors of AIP in type 2 diabetic patients ( P<0.01) . Conclusions:AIP is positively correlated with insulin resistance and negatively correlated with insulin sensitivity. VLDL-C and HOMA IR-CP are independent predictors of AIP.
ABSTRACT
Abstract Background The association between the Metabolically Healthy Obese (MHO) phenotype in the absence of metabolic syndrome and subsequent cardiovascular disease remains unclear. Objectives We examined the association between MHO and CVD risk in young Iranian women. Methods We studied 183 women aged 20-35 years from a population of 308 candidates. We classified participants into 4 phenotypes. We measured body composition, blood pressure, and biochemical factors in all participants. Results The Metabolically Healthy Normal Weight (MHNW) and Normal Weight Obese (NWO) phenotypes had no statistical differences in any biochemistry variables. FBS, TG, LDL/HDL, Cholesterol/HDL, hs-CRP, and atherogenic index of plasma (AIP) were all higher in Metabolically Unhealthy Obese (MUO) than MHO individuals, whereas HDL was higher in MHO than in MUO individuals. LDL/HDL and hs-CRP were higher in MHO participants than MHNW participants, whereas HDL-c was higher in MHNW than MHO. Conclusions Results of the present study demonstrate that young women displaying the MHO phenotype have a favorable metabolic profile as shown by lower FBS, TG, LDL-c/HDL, Cho/HDL, hs-CRP, and AIP and higher HDL levels than the MUO phenotype. However, MHO individuals were still at greater risk of CVD incidence (lower HDL and higher hs-CRP levels) than MHNW individuals.
Resumo Contexto A associação entre o fenótipo obeso metabolicamente saudável (OMS) na ausência de síndrome metabólica e doença cardiovascular subsequente permanece incerta. Objetivos Examinamos a associação entre o fenótipo OMS e risco de DCV em jovens iranianas. Métodos Analisamos 183 mulheres com idade de 20-35 anos de uma população de 308 candidatas. Classificamos as participantes em quatro fenótipos. Mensuramos composição corporal, pressão arterial e fatores bioquímicos em todas as participantes. Resultados Os fenótipos com peso normal metabolicamente saudável (PNMS) e obeso com peso normal não apresentaram diferenças estatísticas em nenhuma das variáveis bioquímicas. Os níveis de glicemia sanguínea em jejum (GSJ), triglicerídeos (TG), relação LDL/HDL, HDL, proteína C reativa ultrassensível (PCR-us) e índice aterogênico do plasma (IAP) foram mais elevados em obesas metabolicamente não saudáveis (OMNS) do que em indivíduos OMSs, enquanto o HDL foi maior em OMSs do que em indivíduos OMNSs. A relação LDL/HDL e o nível de PCR-us foram mais elevados em participantes OMSs do que em participantes com PNMS, enquanto o HDL foi maior naquelas com PNMS do que nas OMSs. Conclusões Os resultados do presente estudo demonstram que mulheres jovens com o fenótipo OMS têm um perfil metabólico favorável, conforme demonstrado pelos níveis menores de GSJ, TG, relação LDL/HDL, HDL, PCR-us e IAP e pelos níveis maiores de HDL em comparação às mulheres com o fenótipo OMNS. Entretanto, indivíduos OMSs ainda apresentavam maior risco de DCV incidente (níveis menores de HDL e maiores de PCR-us) do que indivíduos com PNMS.

Diabetes mellitus interferes with the metabolism of carbohydrates, causing chronic hyperglycemia. Dyslipidemiain diabetes is a condition that leads to cardiovascular disease. This study was aimed to evaluate the effect of hydroalcoholic Prosopis ruscifolia (Pr) leaves extract on hyperglycemia and lipid profile in normo- and hyperglycemicmice. Mice hyperglycemia was induced by alloxan, animals were treated with Pr (50, 100, 200 mg/kg, p.o., 28 days).Fasted blood glucose level on days 7, 14, 21, and 28 was determined. Blood glucose remained within the normalrange in the groups of normoglycemic animals treated with Pr. In the hyperglycemic animals, 100 mg/kg of Pr extractreduced the glycemia, this effect became markedly evident since day 7, until the end of experimental period (p <0.0001), the total reduction reached was 60%. The lipid profile of normal and hyperglycemic mice was evaluated with100 mg/kg, on day 28. A non-significant increase in total cholesterol and low density cholesterol, in hyperglycemicanimals treated with vehicle, and a statistically significant increase (p < 0.0001) in the level of triglyceride and verylow density cholesterol (VLDL) level (p < 0.0001) in normoglycemic animals treated with Pr, compared to the controlgroup were denoted. This could indicate that Pr has a stimulating action on insulin secretion, since hyperinsulinemiais also associated with an increase in the quantity of atherogenic particles of VLDL cholesterol and triglycerides.The coronary risk index and the atherogenic index of hyperglycemic animals treated with Pr showed a reductioncompared with the untreated hyperglycemic ones. The presence of three piperidine alkaloids, juliprosopine, 3’’’’–Oxo-juliprosopine, and julifloridine, previously isolated from P. juliflora, was confirmed. Also, the presence of theflavonoid quercetin was detected in this plant. Those compounds are strong candidates presumably responsible forimparting the effect on glycemia and lipid profile reported here.
ABSTRACT
Background: Metabolic syndrome is described as the clustering of obesity, aberrant glucose metabolism, dyslipidemia and hypertension. A characteristic pattern, termed diabetic dyslipidemia, consists of low HDL, increased triglycerides and postprandial lipemia. This pattern is most frequently seen in type 2 diabetes and may be a treatable risk factor for subsequent cardiovascular disease. This study was designed to compare the hypolipidemic activity of Coriandrum sativum L. with the standard antidiabetic drug, metformin in streptozotocin induced diabetic rats.Methods: Streptozotocin (STZ) was used to induce diabetes in the rats. The hypolipidemic activity of Coriandrum sativum seed extract was compared to the standard drug metformin. 4 groups (n=8) (normal control, diabetic control, streptozotocin+Coriandrum sativum and streptozotocin+metformin). The drugs were administered once daily for 28 days following which lipid profile was estimated on 28th day by using blood sample collected from the retro-orbital space.Results: STZ induced diabetes and also lead to dyslipidemia. Oral administration of CS seed extracts significantly lowered total cholesterol (TC), LDL:HDL ratio, TC:HDL ratio, thus, reducing the cardiovascular risk. HDL levels were slightly increased with CS seed extract compared to diabetic control group but not statistically significant. There was also statistically insignificant reduction in the atherogenic index with CS seed extract compared to diabetic control.Conclusions: CS seed extract (40 mg/kg) orally may have considerable therapeutic benefit as a hypolipidemic agent and can be suggested as a potential dietary add on.
ABSTRACT
Objectives There is absolute lacking of evidences on atherogenic index of plasma (AIP) and its association with cardiovascular disease (CVD) risk factors among postmenopausal women of Bangladesh. This prompted us to investigate this association between AIP and CVD risk factors among postmenopausal women in a rural setting. Methods This cross-sectional study recruited 265 postmenopausal women aged 40–70 years who visited a primary health-care center of Bangladesh. We used modified STEP-wise approach for the Surveillance of Noncommunicable diseases risk factors questionnaire of the World Health Organization to collect data on sociodemographic and behavioral risk factors. Physical measurements were carried out following the method described in the ‘noncommunicable disease risk factors survey Bangladesh 2010’. AIP was determined by the logarithmic transformation of triglyceride to high-density lipoprotein ratio, and association with CVD risk factors were examined by multiple linear regression analysis. Results Overall 35.5% respondents had a high risk level of AIP with a mean of 0.16 ± 0.25. After adjusting the confounders, CVD risk factors including duration of menopause (β = 0.606, p = 0.043), waist–hip ratio (β = 0.165, p = 0.003), 2-h plasma glucose (β = 0.118, p = 0.04), total cholesterol (β = 1.082, p < 0.001), low-density lipoprotein cholesterol (β = −1.044, p < 0.001), and metabolic equivalent of tasks (β = −0.171, p = 0.003) showed a significant association with AIP. Conclusion High AIP and its significant association with CVD risk factors demand proper lifestyle intervention for postmenopausal women of Bangladesh.
ABSTRACT
Objective To observe the abnormality of lipid metabolism and renal function change in elderly patients with hypertension,and to evaluate the relationship between atherogenic index of plasma(AIP) and glomerular filtration rate(GFR).Methods From July 2015 to June 2017,in Quzhou People's Hospital,182 elderly patients with hypertension were selected as observation group,and 192 elderly healthy people with normal blood pressure were selected as control group.The total cholesterol(TC),triglyeride(TG),high density lipoprotein cholesterol (HDL-C) were detected,and the AIP =1og [TG/HDL-C] was calculated.The GFR was estimated by Cockcroft-Gault equation.The relationship between the estimated GFR (eGFR) and the blood lipid parameters was analyzed.Results The eGFR of the observation group and control group were (84.94 ± 19.49) mL · min-1 · (1.73m2)-1,(154.91 ± 20.44) mL· min-1 · (1.73m2)-1,respectively,the difference between the two groups was statistically significant (t =11.27,P ＜ 0.01).The AIP of the observation group and control group were (0.68 ± 0.03),(-0.22 ± 0.02),respectively,the difference between the two groups was statistically significant (t =3.43,P ＜ 0.01).There was a negative correlation between AIP and eGFR in the elderly patients with hypertension (r =-0.845,P ＜ 0.01).Conclusion The fact shows that abnormality of lipid metabolism in the elderly patients with hypertension is present.AIP can be used as a plasma marker of atherosclerosis and could be used as a useful and important parameter for clinical observation in the elderly hypertensive patients with renal impairment.
ABSTRACT
Objective@#To study the relationship between atherogenic index of plasma (AIP)and renal impairment in male patients with gout.@*Methods@#A retrospective analysis of 821 male subjects was conducted to measure the relevant biochemical indicators and to calculate the AIP, endogenous creatinine-clearance rate (Ccr), and estimated glomerular filtration rate (eGFR). EpiData 3.1 software was used for data entry, SPSS21.0 was used for statistical analysis, and GraphPad Prism 6.0 software was used for charts.@*Results@#Compared with control group, AIP, serum uric acid, triglyceride in gout group were significantly higher (all P<0.01), while eGFR and high density lipoprotein-cholesterol were significantly lower (both P<0.05). The composition ratio of renal function impairment in gout group was significantly higher (P<0.01). With the increase of AIP level, eGFR level decreased and serum creatinine level increased, but the overall difference was not statistically significant (P>0.05), while Ccr and serum uric acid levels gradually increased (P<0.05). Logistic regression analysis after adjusting for various confounding factors showed that AIP, triglyceride, and serum uric acid were risk factors for renal function damage in patients with gout (P<0.05), the relevant risk were 7.030, 1.291, 1.004 respectively. After adjusting confounding factors, the associations between triglyceride, serum uric acid and renal function injury risk changed little, while AIP showed more evident, the OR value increased from 2.629 to 6.265 and 7.030.@*Conclusions@#(1)AIP is closely related to the renal function damage of patients with gout. After adjusting various confounding factors, AIP can better reflect the renal function damage than other indicators, which is of great significance to predict the renal function damage of patients with gout.

ABSTRACT
Antiobesity effect of phenolic rich fractions of fresh fruits of Solanum aethiopicum and Solanum macrocapon on cafeteria diet (CD)-induced obesity was investigated using Wistar rats to explore the potential of S. macrocapon and S. aethiopicum in the management of obesity. Phenolic-rich extracts (free and bound phenolics) were obtained from S. macrocapon and S. aethiopicum by extraction with 80% (v/v) acetone and ethyl acetate respectively. Obesity was induced in Wistar rats with CD for 42 days after which they were treated with phenolic-rich extracts of S. aethiopicum and S. macrocapon at 200 mg/kg BW and 400 mg/kg BW for six weeks. Body weights and blood glucose were monitored weekly. Lipid profiles (Total Cholesterol (TC), Triglyceride (TG), High Density Lipoprotein -cholesterol (HDL-C), Very Low Density Lipoprotein – cholesterol (VLDL-C) and Low Density Lipoprotein – cholesterol (LDL-C)), Aspartate Transaminase (AST), Alanine Transaminase (ALT), Alkaline Phosphatase (ALP), urea, creatinine, total protein, albumin, atherogenic coefficient (AC) and cardiac risk ratio (CRR) were estimated in the plasma. Treatment with phenolic-rich extracts of S. macrocapon and S. aethiopicum caused decrease in lee index, atherogenic coefficient, blood glucose level, plasma TC, TG, LDL-c, VLDL-c, ALT, AST, AC, CRR and increase in HDL-c, urea, creatinine, total protein and albumin concentrations relative to the obese rats. Conclusively, the phenolic-rich extracts of S. macrocapon and S. aethiopicum possess antiobesity potential and could be employed in the management of obesity.
