Lipoprotein Cholesterol (lipoprotein + cholesterol)
Kinds of Lipoprotein Cholesterol Terms modified by Lipoprotein Cholesterol Selected AbstractsProspective Association Between Low and High Total and Low-Density Lipoprotein Cholesterol and Coronary Heart Disease in Elderly MenJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 12 2004J. David Curb MD Objectives: To examine the relationship between total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) and the incidence of coronary heart disease (CHD) in elderly men. Design: Prospective. Setting: Population based. Participants: A sample of 2,424, Japanese-American men aged 71 to 93 was used. Measurements: Six years of data on incident fatal plus nonfatal CHD were examined. Results: Analysis revealed a significant U-shaped relationship between age-adjusted CHD rates and both TC and LDL-C. The ranges of TC and LDL-C with the lowest risk of CHD were 200 to 219 mg/dL and 120 to 139 mg/dL, respectively. As cholesterol concentrations declined and increased beyond these ranges, the risk of CHD increased. These U-shaped relationships remained significant after adjusting for age and other risk factors. Conclusion: The U-shaped associations between TC and LDL-C and CHD imply a complex relationship between lipids and CHD in late life. The results indicate that elevated lipid levels should continue to be treated in healthy elderly individuals, as they are in those who are younger, although pharmacologically lowering lipids to excessively low levels in the elderly may warrant further study, as does the contribution of subclinical frailty to the relationship of lipids to CHD risk. [source] The Value of Serum Albumin and High-Density Lipoprotein Cholesterol in Defining Mortality Risk in Older Persons with Low Serum CholesterolJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2001Stefano Volpato MD OBJECTIVES: To investigate the relationship between low cholesterol and mortality in older persons to identify, using information collected at a single point in time, subgroups of persons with low and high mortality risk. DESIGN: Prospective cohort study with a median follow-up period of 4.9 years. SETTINGS: East Boston, Massachusetts; New Haven, Connecticut; and Iowa and Washington counties, Iowa. PARTICIPANTS: Four thousand one hundred twenty-eight participants (64% women) age 70 and older at baseline (mean 78.7 years, range 70,103); 393 (9.5%) had low cholesterol, defined as ,160 mg/dl. MEASUREMENTS: All-cause mortality and mortality not related to coronary heart disease and ischemic stroke. RESULTS: During the follow-up period there were 1,117 deaths. After adjustment for age and gender, persons with low cholesterol had significantly higher mortality than those with normal and high cholesterol. Among subjects with low cholesterol, those with albumin> 38 g/L had a significant risk reduction compared with those with albumin ,38 g/L (relative risk (RR) = 0.57; 95% confidence interval (CI) = 0.41,0.79). Within the higher albumin group, high-density lipoprotein cholesterol (HDL-C) level further identified two subgroups of subjects with different risks; participants with HDL-C <47 mg/dl had a 32% risk reduction (RR = 0.68; 95% CI = 0.47,0.99) and those with HDL-C ,47 mg/dl had a 62% risk reduction (RR = 0.38; 95% CI = 0.20,0.68), compared with the reference category; those with albumin ,38 g/L and HDL-C <47 mg/dl. CONCLUSIONS: Older persons with low cholesterol constitute a heterogeneous group with regard to health characteristics and mortality risk. Serum albumin and HDL-C can be routinely used in older patients with low cholesterol to distinguish three subgroups with different prognoses: (1) high risk (low albumin), (2) intermediate risk (high albumin and low HDL-C), and (3) low risk (high albumin and high HDL-C).

[source] Adiponectin Is a Link Among Inflammation, Insulin Resistance, and High-Density Lipoprotein Cholesterol But Is Not Associated With Paraoxonase Activity in Premenopausal WomenJOURNAL OF CLINICAL HYPERTENSION, Issue 11 2009Pinar Cetinalp-Demircan PhD The aim of this study was to evaluate whether insulin sensitivity, inflammatory response, and plasma lipid profile are associated with circulating adiponectin levels in nondiabetic healthy women. The authors also assessed whether adiponectin has any effect on high-density lipoprotein cholesterol,linked paraoxonase 1 (PON-1) activity and on the susceptibility of low-density lipoproteins to oxidation. Plasma adiponectin was measured in 91 nondiabetic premenopausal women, and the patients were then divided into quartiles. Circulating adiponectin was found to be associated with body mass index (r=.55, P<.001). After adjustment for body mass index, adiponectin showed an inverse correlation with the homeostasis model assessment of insulin resistance (HOMA-IR) (r=,.41, P<.001) and a positive correlation with high-density lipoprotein cholesterol (r=.43, P<.001). In linear regression analysis, HOMA-IR, tumor necrosis factor ,, and high-density lipoprotein cholesterol levels were found to be independently associated with adiponectin. However, high-density lipoprotein cholesterol,linked PON-1 activity and the susceptibility of low-density lipoproteins to in vitro oxidation did not seem to be related to plasma adiponectin concentrations. [source] Effect of Orlistat in Obese Patients With Heart Failure: A Pilot StudyCONGESTIVE HEART FAILURE, Issue 3 2005Luís Beck-da-Silva MD Heart failure is the leading cause of hospitalization. Obesity is increasingly common and is a major public health problem. The aim of this study is to assess whether obese patients with heart failure can benefit from losing weight via an orlistat-assisted diet. This randomized clinical trial included obese patients with ejection fractions ,40%. Orlistat and diet counseling were compared with diet counseling alone. Twenty-one consecutive obese patients with heart failure were recruited. Significant improvement in 6-minute walk test (45.8 m; 95% confidence interval, 5.2,86.4 m; p=0.031), functional class (,0.6±0.5, p=0.014), weight loss (,8.55 kg; 95% confidence interval, ,13.0 to ,4.1 kg;p<0.001) and also significant decreases in total cholesterol (p=0.017), low-density lipoprotein cholesterol (p=0.03), and triglycerides (p=0.036) were observed in the orlistat group. Orlistat can promote significant weight loss and symptoms of relief in obese patients with heart failure, as measured by 6-minute walk test and functional capacity. The lipid profile improved. Orlistat was safe and well tolerated. [source] A double-blind, placebo-controlled trial of rosiglitazone for clozapine-induced glucose metabolism impairment in patients with SchizophreniaACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009D. C. Henderson Objective:, The primary purpose of this 8-week double-blind, placebo-controlled trial of rosiglitazone 4 mg/day was to examine its effect on insulin sensitivity index (SI) and glucose utilization (SG) in clozapine-treated subjects with schizophrenia with insulin resistance. Method:, Eighteen subjects were randomized and accessed with a Frequently Sampled Intravenous Glucose Tolerance Test (FSIVGTT) at baseline and at week 8 to estimate SG and SI. Results:, Controlling for the baseline, comparing the rosiglitazone group with placebo group, there was a non-significant improvement in SG (0.016 ± 0.006,0.018 ± 0.008, effect size = 0.23, P = 0.05) with a trend of improvement in SI in the rosiglitazone group (4.6 ± 2.8,7.8 ± 6.7, effect size = 0.18, P = 0.08). There was a significant reduction in small low-density lipoprotein cholesterol (LDL-C) particle number (987 ± 443,694 ± 415, effect size = 0.30, P = 0.04). Conclusion:, Rosiglitazone may have a role in addressing insulin resistance and lipid abnormalities associated with clozapine. [source] Interpreting clinical trials of diabetic dyslipidaemia: new insightsDIABETES OBESITY & METABOLISM, Issue 3 2009A. S. Wierzbicki Current treatment guidelines highlight the importance of aggressive lipid-modifying therapy in reducing cardiovascular risk in patients with type 2 diabetes. Statins are established as the cornerstone of dyslipidaemia management in diabetic patients, based on their efficacy in lowering levels of low-density lipoprotein cholesterol (LDL-C). However, statins fail to address the high residual cardiovascular risk in treated patients, some of which may be attributable to low HDL cholesterol (HDL-C) and elevated triglycerides and to a preponderance of small, dense LDL particles, indicating the need for further intervention. Fibrates are effective against all components of atherogenic dyslipidaemia associated with type 2 diabetes. Clinical studies, most notably the Fenofibrate Intervention and Event Lowering in Diabetes, indicate that fibrates, most likely in combination with a statin, have a secondary role in reducing cardiovascular risk in patients with type 2 diabetes, particularly in those without prior cardiovascular disease or patients with low HDL-C. Results are awaited from the ongoing Action to Control Cardiovascular Risk in Diabetes trial to fully evaluate the outcome benefits of this combination strategy. [source] Tagatose, a new antidiabetic and obesity control drugDIABETES OBESITY & METABOLISM, Issue 2 2008Y. Lu A potentially important new drug for treating type 2 diabetes, tagatose, is now in phase 3 clinical trial. The history, development, additional health benefits, mechanisms of action and the potential for the drug are presented in context with a review of the rapidly growing epidemic of type 2 diabetes and treatments for it. An epimer of fructose, the natural hexose tagatose was originally developed by Spherix Incorporated (formerly Biospherics Inc.) as a low-calorie sugar substitute. Only 20% of orally ingested tagatose is fully metabolized, principally in the liver, following a metabolic pathway identical to that of fructose. Following a decade of studies, tagatose became generally recognized as safe for use in foods and beverages under US FDA regulation. The simple sugar is commercially produced by isomerization of galactose, which is prepared from lactose. Early human studies suggested tagatose as a potential antidiabetic drug through its beneficial effects on postprandial hyperglycaemia and hyperinsulinaemia. A subsequent 14-month trial confirmed its potential for treating type 2 diabetes, and tagatose showed promise for inducing weight loss and raising high-density lipoprotein cholesterol, both important to the control of diabetes and constituting benefits independent of the disease. Furthermore, tagatose was shown to be an antioxidant and a prebiotic, both properties cited in the maintenance and promotion of health. No current therapies for type 2 diabetes provide these multiple health benefits. The predominant side effects of tagatose are gastrointestinal disturbances associated with excessive consumption, generally accommodated within 1- to 2-week period. The health and use potentials for tagatose (branded Naturlose® for this use) are given with respect to current type 2 diabetes drugs and markets. Under an FDA-affirmed protocol, Spherix is currently conducting a phase 3 trial to evaluate a placebo-subtracted treatment effect based on a decrease in HbA1c levels. Side effects, contraindications and possibly beneficial new findings will be carefully monitored. It is hoped that early results of the trial may become available by mid-2008. If a subsequent NDA is successful, tagatose may fill a major health need. [source] Elevated C-reactive protein in Native Canadian children: an ominous early complication of childhood obesityDIABETES OBESITY & METABOLISM, Issue 5 2006R. Retnakaran Aim:, Subclinical inflammation has been proposed as a pathophysiologic mechanism linking obesity with vascular and metabolic disease. Native North American populations are experiencing high prevalence rates of both (i) childhood obesity and (ii) adult cardiovascular disease (CVD) and type 2 diabetes. Thus, we sought to determine whether subclinical inflammation is an early complication of obesity in Native children. Methods:, Serum concentrations of the inflammatory biomarker C-reactive protein (CRP) were assessed in a population-based, cross-sectional study of the Sandy Lake Oji-Cree community of Northern Ontario, Canada, involving 228 children aged 10,19 years (mean age 14.8). Results:, Median CRP in this population was 0.5 mg/l (interquartile range 0.18,1.79 mg/l). CRP levels were higher than age-matched reference data from the Third National Health and Nutrition Examination Survey (NHANES III). Importantly, fully 15.8% of the children of this community had CRP concentrations between 3 and 10 mg/l, a range that identifies adults at high risk of CVD. Moreover, increasing CRP concentration in this paediatric population was associated with an enhanced CV risk profile, consisting of increased adiposity, higher insulin resistance, worsening lipid profile (higher total cholesterol, triglycerides, low-density lipoprotein cholesterol, apolipoprotein B and total cholesterol : high-density-lipoprotein cholesterol ratio), increased leptin and decreased adiponectin. On multivariate analysis, waist circumference and interleukin-6 (IL-6) emerged as independent determinants of CRP concentration. Conclusion:, Subclinical inflammation is an early complication of childhood obesity in Native children and may foreshadow an increased burden of CVD and type 2 diabetes in the future. [source] Insulin resistance , a common link between type 2 diabetes and cardiovascular diseaseDIABETES OBESITY & METABOLISM, Issue 3 2006Harold E. Lebovitz Evidence suggests that diabetes and cardiovascular disease (CVD) may share an underlying cause(s), a theory known as the ,common soil' hypothesis. Insulin resistance is central both to the progression from normal glucose tolerance to type 2 diabetes and to a constellation of cardiovascular risk factors known as the metabolic syndrome. These risk factors include visceral obesity and dyslipidaemia characterized by low levels of high-density lipoprotein cholesterol, hypertriglyceridaemia and raised small dense low-density lipoprotein particle levels. Changes in adipose tissue mass and metabolism may link insulin resistance and visceral obesity, a condition that is common in type 2 diabetes. Furthermore, weight reduction, increased physical activity, metformin and acarbose have been shown to reduce the development of type 2 diabetes in genetically predisposed subjects and may decrease the high cardiovascular risk of patients with diabetes. Some fatty acid derivatives can affect energy metabolism by activating peroxisome proliferator-activated receptors (PPARs), nuclear receptors that play a key role in energy homeostasis. These receptors represent an ideal therapeutic target for reducing cardiovascular risk, because they are involved in the regulation of both insulin action and lipid metabolism. In addition to lifestyle changes, PPAR, agonists such as thiazolidinediones are frequently beneficial and have been shown to ameliorate insulin resistance, while activation of PPAR, (e.g. by fibrates) can lead to improvements in free fatty acid oxidation and lipid profile, and a reduction in cardiovascular events. The development of agents with both PPAR, and PPAR, activity promises added benefits with amelioration of insulin resistance, delayed progression to and of type 2 diabetes and a reduction of CVD. [source] Effect of a nutritional liquid supplement designed for the patient with diabetes mellitus (Glucerna SR) on the postprandial glucose state, insulin secretion and insulin sensitivity in healthy subjectsDIABETES OBESITY & METABOLISM, Issue 3 2006M. González-Ortiz Aim:, To identify the effect of a nutritional liquid supplement designed for the patient with diabetes mellitus (Glucerna SR) in single administration on the postprandial glucose state, insulin secretion and insulin sensitivity in healthy subjects. Methods:, A randomized, single-blind, cross-over, clinical trial was carried out in 14 young, healthy, non-obese, volunteers. A basal metabolic profile, which included glucose level, insulin, total cholesterol, high-density lipoprotein and low-density lipoprotein cholesterol, triglycerides, creatinine, and uric acid, was measured. Subjects received a single administration of 300 kcal, gauged with water at 350 ml, of each of the following (at least 3 days apart): glucose 75 g, polymeric supplement (Ensure high calcium) 315 ml or Glucerna SR 323 ml. At the beginning of each administration and 30, 60, 90 and 120 min later, glucose and insulin concentrations were measured. Areas under the curve of glucose and insulin were calculated. First-phase and total insulin secretions and insulin sensitivity were also estimated. Results:, Glucose level at 120 min was significantly lower after receiving Ensure high calcium or Glucerna SR. Administration of Glucerna SR resulted in a significant reduction in the areas under the curve of glucose and insulin, as well as in total insulin secretion with a tendency to be lower in their first phase. Insulin sensitivity was increased. Conclusions:, A single administration of Glucerna SR to healthy subjects decreased the postprandial glucose and insulin states, as well as the insulin secretion; insulin sensitivity increased. [source] Efficacy and safety of ezetimibe co-administered with simvastatin in thiazolidinedione-treated type 2 diabetic patientsDIABETES OBESITY & METABOLISM, Issue 1 2005L. M. Gaudiani Aim:, In patients with type 2 diabetes mellitus (T2DM), combination therapy is usually required to optimize glucose metabolism as well as to help patients achieve aggressive targets for low-density lipoprotein cholesterol (LDL-C) and other lipid parameters associated with cardiovascular risk. The thiazolidinediones (TZDs) are increasingly being used for both their blood glucose-lowering properties and their modest beneficial effects on triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C). Ezetimibe, an intestinal cholesterol absorption inhibitor, has a mechanism of action that differs from that of statins, which inhibit hepatic cholesterol synthesis. We compared the lipid-modifying efficacy and safety of adding ezetimibe to simvastatin, vs. doubling the dose of simvastatin, in TZD-treated T2DM patients. Methods:, This was a randomized, double-blind, parallel group, multicentre study in T2DM patients, 30,75 years of age, who had been on a stable dose of a TZD for at least 3 months and had LDL-C > 2.6 mmol/l (100 mg/dl) prior to study entry. Other antidiabetic medications were also allowed. Following 6 weeks of open-label simvastatin 20 mg/day, patients were randomized to the addition of either blinded ezetimibe 10 mg/day (n = 104) or an additional blinded simvastatin 20 mg/day (total simvastatin 40 mg/day; n = 110) for 24 weeks. Patients were stratified according to TZD type and dose (pioglitazone 15,30 vs. 45 mg/day; rosiglitazone 2,4 vs. 8 mg/day). Results:, LDL-C was reduced more (p < 0.001) by adding ezetimibe 10 mg to simvastatin 20 mg (,20.8%) than by doubling the dose of simvastatin to 40 mg (,0.3%). Ezetimibe plus simvastatin 20 mg also produced significant incremental reductions in non-HDL-C (p < 0.001), very low-density lipoprotein cholesterol (p < 0.05) and apolipoprotein B (p < 0.001) relative to simvastatin 40 mg. There were no differences between the groups with respect to changes in TG and HDL-C levels, and both treatments were well tolerated. Conclusions:, Co-administration of ezetimibe with simvastatin, a dual inhibition treatment strategy targeting both cholesterol synthesis and absorption, is well tolerated and provides greater LDL-C-lowering efficacy than increasing the dose of simvastatin in T2DM patients taking TZDs. [source] Lipids and lipoprotein(a) concentrations in Pakistani patients with type 2 diabetes mellitusDIABETES OBESITY & METABOLISM, Issue 5 2004S. S. Habib Aim:, The aim of the present study was to analyze serum lipoprotein(a) [Lp(a)] levels in Pakistani patients with type 2 diabetes mellitus (DM) and to find correlations between clinical characteristics and dyslipidaemias in these patients. Methods:, Fasting blood samples were analyzed for Lp(a), total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), glucose and glycosylated haemoglobin (HbA1c) in 68 Pakistani patients with type 2 DM and 40 non-diabetic healthy control subjects. Results:, Lp(a) levels were significantly raised in diabetics as compared to the control group. No correlation of Lp(a) was seen with age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP) and fasting glucose. There was a positive correlation of BMI to SBP and DBP. There was a significant positive correlation between Lp(a) and total cholesterol and LDL-c. No correlation of Lp(a) was observed with HDL-c, triglycerides and glycosylated haemoglobin (HbA1c). Conclusion:, The present study led us to conclude that serum Lp(a) levels are significantly raised in type 2 DM and have a positive correlation with serum total and LDL-c levels. [source] Brachial-ankle pulse wave velocity and cardiovascular risk factors in the non-diabetic and newly diagnosed diabetic Chinese: Guangzhou Biobank Cohort Study-CVDDIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 2 2010Lin Xu Abstract Background Increased arterial stiffness is an important cause of cardiovascular disease (CVD). We examined determinants of arterial stiffness in subjects across strata of glycaemic status. Methods A total of 1249 subjects from a sub-study of the Guangzhou Biobank Cohort Study (GBCS-CVD) had brachial-ankle pulse wave velocity (baPWV) measured by automatic oscillometric method. Major cardiovascular risk factors including glycosylated haemoglobin A1c (HbA1c), high sensitivity C-reactive protein (hsCRP), fasting triglyceride, low- and high-density lipoprotein cholesterol and both fasting and post 2-h oral glucose-load glucose, systolic and diastolic blood pressure were assessed. Results In all, 649, 479 and 121 subjects were classified into normoglycaemia, impaired glucose metabolism (IGM) and newly diagnosed diabetes groups, respectively. Both age and systolic blood pressure were significantly associated with increased baPWV in all three groups (all p < 0.001). In both normoglycaemic and IGM groups, hsCRP and HbA1c were positively associated with baPWV (p from 0.04 to < 0.001), whereas current smoking and triglyceride were associated with baPWV in the normoglycaemic and IGM group, respectively (p = 0.04 and 0.001). No gender difference in baPWV was observed in the normoglycaemic or IGM groups. However, in the newly diagnosed diabetes group, men had higher baPWV than women (p = 0.01). Conclusions In the normoglycaemic and IGM subjects, after adjusting for age, blood pressure and other confounders, increasing HbA1c was associated with increased baPWV, suggesting a pathophysiological role of chronic glycaemia that can contribute to vascular disease risk in persons without diabetes.

[source] Lipid-lowering therapy in patients with type 2 diabetes: the case for early interventionDIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 4 2008Armin Steinmetz Abstract Chronic complications of type 2 diabetes, in particular, macrovascular complications, confer substantial morbidity and mortality and adversely affect a patient's quality of life. Early intensive intervention to control cardiovascular risk factors is essential in clinical management. Atherogenic dyslipidaemia characterized by elevated triglycerides, a low level of high-density lipoprotein cholesterol (HDL-C), and an increase in the preponderance of small, dense low-density lipoprotein (LDL) particles, is a key modifiable risk factor for macrovascular diabetic complications. Lowering low-density lipoprotein cholesterol (LDL-C) with a statin (or the combination of statin and ezetimibe) is the main focus for reducing cardiovascular risk in patients with diabetes. However, statins fail to address the residual cardiovascular risk associated with low HDL-C. Fibrates are effective against all components of the atherogenic dyslipidaemia associated with type 2 diabetes. Secondary analyses of the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study suggest a role for early treatment with fenofibrate in improving cardiovascular risk reduction in type 2 diabetes and provide safety data supporting the use of fenofibrate in combination with a statin. Data from the FIELD study suggest that fenofibrate may also have potential to impact on microvascular diabetic complications associated with type 2 diabetes. Data are awaited from the ongoing Action to Control Cardiovascular Risk in Diabetes (ACCORD) study to evaluate the outcome benefits of combining fenofibrate with a statin in patients with type 2 diabetes. Finally, in view of divergent study results and outstanding data, assessment of the risk of the individual with type 2 diabetes is mandatory to assist clinical decision-making when initiating lipid therapy. Copyright © 2008 John Wiley & Sons, Ltd. [source] Effect of ABCA1 variant on atherogenic dyslipidaemia in patients with Type 2 diabetes treated with rosiglitazoneDIABETIC MEDICINE, Issue 6 2009S. E. Park Abstract Aims, To investigate the effect of two common ATP-binding cassette transporter 1 (ABCA1) polymorphisms (rs4149263 and rs2020927) on atherogenic dyslipidaemia in Korean Type 2 diabetic patients who were treated with rosiglitazone. Patients and methods, Two hundred and fifty-six patients with Type 2 diabetes who had never previously received peroxisome proliferator-activated receptor gamma (PPAR-,) agonists or lipid-lowering treatment were treated with 4 mg of rosiglitazone daily for 12 weeks without any adjustment to their glucose-lowering regimen. The primary outcome was the change in atherogenic index of plasma (AIP), calculated as log [triglyceride (mmol/l)/high-density lipoprotein cholesterol (mmol/l)], before and after rosiglitazone treatment. The effect of rosiglitazone on the change in AIP was compared across the ABCA1 single nucleotide polymorphisms (SNPs) rs41429263 and rs2020927. Results, Before adjustment, the change in AIP at 12 weeks was significantly different across the rs4149263 genotypes [median (interquartile range): ,0.05 (,0.21, 0.09) for TT; 0.02 (,0.09, 0.17) for TC; and 0.11 (0.03, 0.25) for CC; P = 0.003], but not across the rs2020927 [,0.04 (,0.18, 0.10) for TT; 0.03 (,0.17, 0.15) for TC; and ,0.03 (,0.13, 0.10) for CC; P = 0.401]. After controlling for age, gender and duration of diabetes, the presence of the C-allele was significantly associated with an increase in AIP by 0.13 [95% confidence interval (CI), 0.04,0.21; P = 0.003]. This association did not change significantly when body mass index and pretreatment metabolic parameters were additionally controlled for (the change in AIP: 0.14; 95% CI, 0.04,0.24; P = 0.007). Conclusions, The ABCA1 SNP rs4149263 may be associated with the change in atherogenic lipid profile in Type 2 diabetes treated with rosiglitazone. [source] Prevalence and projections of diabetes and pre-diabetes in adults in Sri Lanka,Sri Lanka Diabetes, Cardiovascular Study (SLDCS)DIABETIC MEDICINE, Issue 9 2008P. Katulanda Abstract Aims To determine the prevalence of diabetes mellitus and pre-diabetes (impaired fasting glucose and impaired glucose tolerance) in adults in Sri Lanka. Projections for the year 2030 and factors associated with diabetes and pre-diabetes are also presented. Methods This cross-sectional study was conducted between 2005 and 2006. A nationally representative sample of 5000 adults aged , 18 years was selected by a multi-stage random cluster sampling technique. Fasting plasma glucose was tested in all participants and a 75-g oral glucose tolerance test was performed in non-diabetic subjects. Prevalence was estimated for those > 20 years of age. Results Response rate was 91% (n = 4532), males 40%, age 46.1 ± 15.1 years (mean ± standard deviation). The age,sex standardized prevalence (95% confidence interval) of diabetes for Sri Lankans aged , 20 years was 10.3% (9.4,11.2%) [males 9.8% (8.4,11.2%), females 10.9% (9.7,12.1%), P = 0.129). Thirty-six per cent (31.9,40.1%) of all diabetic subjects were previously undiagnosed. Diabetes prevalence was higher in the urban population compared with rural [16.4% (13.8,19.0%) vs. 8.7% (7.8,9.6%); P < 0.001]. The prevalence of overall, urban and rural pre-diabetes was 11.5% (10.5,12.5%), 13.6% (11.2,16.0%) and 11.0% (10.0,12.0%), respectively. Overall, 21.8% (20.5,23.1%) had some form of dysglycaemia. The projected diabetes prevalence for the year 2030 is 13.9%. Those with diabetes and pre-diabetes compared with normal glucose tolerance were older, physically inactive, frequently lived in urban areas and had a family history of diabetes. They had higher body mass index, waist circumference, waist,hip ratio, systolic/diastolic blood pressure, low-density lipoprotein cholesterol and triglycerides. Insulin was prescribed to 4.4% (2.7,6.1%) of all diabetic subjects. Conclusions One in five adults in Sri Lanka has either diabetes or pre-diabetes and one-third of those with diabetes are undiagnosed. [source] Plasma triglycerides and LDL cholesterol are related in a parabolic fashion in the general population and patients with Type 2 diabetes mellitus: long-term follow-up results from the Hoorn studyDIABETIC MEDICINE, Issue 9 2008M. C. G. J. Brouwers Abstract Aims Low-density lipoprotein cholesterol (LDL-C) levels are often fairly normal in Type 2 diabetes mellitus (DM). We anticipated that a parabolic relation between plasma triglycerides and LDL-C, as previously demonstrated in familial combined hyperlipidaemia (FCHL), might account for this phenomenon. Methods Our hypothesis was tested in 1343 subjects derived from the general population who were studied on two occasions 6 years apart (the Hoorn study). Three groups were constructed depending on plasma triglycerides: group A (individuals with both measurements below 1.5 mmol/l), group B (one measurement below and one above 1.5 mmol/l) and group C (both measurements above 1.5 mmol/l). Diabetes status was ascertained by an oral glucose tolerance test. Results In a mixed linear model, a significant, positive relation between triglycerides and LDL-C was observed for males in group A (,a = 0.5, P < 0.001) and group B (,b = 0.2, P < 0.001), whereas a significant negative relation was found for males in group C (,c = ,0.2, P = 0.003). The regression slopes did not differ between diabetic and non-diabetic subjects. Similar results were obtained for women, with the exception that the relation was not significantly negative in group C (,c = ,0.1, P = 0.4). Conclusion Plasma triglcyerides and LDL-C are related in a parabolic fashion, not only in FCHL, but also in the general population and Type 2 DM. These findings aid our interpretation of typical dyslipidaemia and the effects of treatment that are frequently observed in hypertriglyceridaemic states. [source] Evidence for distinct effects of GH and IGF-I in the metabolic syndromeDIABETIC MEDICINE, Issue 9 2007P. Maison Abstract Aims, The metabolic syndrome is a cluster of cardiovascular risk factors which include central obesity, dyslipidaemia, glucose intolerance and hypertension. These risk factors are common in patients with growth hormone (GH) deficiency, suggesting a role for the somatotropic axis in the development of metabolic syndrome. Methods, We used factor analysis to investigate the relationships linking serum levels of GH and insulin-like growth factor I (IGF-I) to metabolic syndrome variables (high-density lipoprotein cholesterol, triglycerides, fasting glucose, blood pressure and waist circumference). We studied 359 men and 388 women from the Data from an Epidemiological Study on the Insulin Resistance syndrome (DESIR). Their age range was 30,64 years. Results, Three independent latent factors explained 61% of the total variance in women and four factors explained 73% in men. In both men and women, IGF-I showed a strong positive correlation with the lipid factor and a negative correlation with the obesity/glucose factor. In women, GH showed a strong negative correlation with the obesity/glucose factor but not the lipid factor. In men, GH was unrelated to the lipid and obesity/glucose factors. The blood pressure factor was not related to GH or IGF-I. In contrast with IGF-I, GH was significantly lower in women with metabolic syndrome (1575 ± 449 pg/ml) than in the other women (2121 ± 520 pg/ml, P = 0.002). No significant difference was observed in men for GH or IGF-I. Conclusion, Our results support a link between the somatotropic axis and several features of the metabolic syndrome, and suggest distinct effects of GH and IGF-I on these parameters. [source] Myocardial perfusion imaging and cardiac events in a cohort of asymptomatic patients with diabetes living in southern FranceDIABETIC MEDICINE, Issue 4 2006A. Sultan Abstract Aims, To assess the association between abnormal stress myocardial perfusion imaging (MPI) and cardiac events (CE) in asymptomatic patients with diabetes and with , 1 additional risk factor. Predictors of abnormal stress MPI were also evaluated. Methods, Four hundred and forty-seven consecutive patients who underwent stress MPI were prospectively followed for 2.1 [0.5,4.1] years for the subsequent occurrence of hard CE (myocardial infarction and sudden or coronary death) and soft CE (unstable angina and ischaemic heart failure requiring hospitalization). Re-vascularization procedures performed as a result of the screening protocol were not included in the analysis. Results, Follow-up was successful in 419 of 447 patients (94%), of whom 71 had abnormal MPI at baseline. Medical therapy was intensified in all subjects and especially in those with abnormal MPI. Twenty-three patients with abnormal MPI underwent a re-vascularization procedure. CEs occurred in 14 patients, including six of 71 patients (8.5%) with abnormal MPI and eight of 348 patients (2.3%) with normal MPI (P < 0.005). Only two patients developed a hard CE and 12 a soft CE. In multivariate analysis, abnormal MPI was the strongest predictor for CEs [odds ratio (OR) (95% CI) = 5.6 (1.7,18.5)]. Low-density lipoprotein cholesterol , 3.35 mmol/l [OR (95% CI) = 7.3; 1.5,34.7] and age > median [OR (95% CI) = 6.0 (1.2,28.6)] were additional independent predictors for CE. The independent predictors for abnormal MPI were male gender, plasma triglycerides , 1.70 mmol/l, creatinine clearance < 60 ml/min and HbA1c > 8%, with male gender the strongest [OR (95% CI) = 4.0 (1.8,8.8)]. Conclusions, Asymptomatic patients with diabetes in this study had a very low hard cardiac event rate over an intermediate period. This could be explained by the effects of intervention or by the low event rate in the background population. Randomized studies of cardiac heart disease screening are required in asymptomatic subjects with diabetes to determine the effectiveness of this intervention. Diabet. Med. (2006) [source] The Relation Between Mitral Annular Calcification and Mortality in Patients Undergoing Diagnostic Coronary AngiographyECHOCARDIOGRAPHY, Issue 9 2006Howard J. Willens M.D. To determine whether the observed association between mitral annular calcification (MAC) and mortality is independent of the severity of coronary artery disease (CAD), we analyzed data from 134 male veterans (age 63 ± 10 years) followed for 5 years who had undergone diagnostic coronary angiography and transthoracic echocardiography within 6 months of each other. Echocardiograms were retrospectively reviewed for the presence of MAC. The relation of MAC to all-cause mortality was analyzed using logistic regression, and odds ratios (OR) were calculated. MAC was present in 49 (37%) subjects. Over the 5-year follow-up period, 38 (28%) patients expired. Five-year survival was 80% for subjects without MAC and 56% for subjects with MAC (P = 0.003). MAC (OR = 3.16, 95% confidence interval [CI]= 1.43,6.96, P = 0.003), ejection fraction (OR = 0.76, 95% CI = 0.59,0.97, P = 0.02), and left main CAD (OR = 2.70, 95% CI = 1.11,6.57, P = 0.02) were significantly associated with mortality in univariate analysis. After adjusting for left ventricular ejection fraction, number of obstructed coronary arteries and the presence of left main coronary artery stenosis, MAC significantly predicted death (OR = 2.48, 95% CI = 1.09,5.68, P = 0.03). Similarly, after adjusting for predictors of MAC, including ejection fraction, age, diabetes, peripheral vascular disease, and heart failure, MAC remained a significant predictor of death (OR = 2.38, 95% CI = 1.02,5.58, P = 0.04). MAC also predicted death independent of smoking status, hypertension, serum creatinine, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and C-reactive protein levels (OR = 3.98, 95% CI = 1.68,9.40, P = 0.001). MAC detected by two-dimensional echocardiography independently predicts mortality and may provide an easy-to-perform and inexpensive way to improve risk stratification. [source] Hepatocyte growth factor is a significant risk factor for white matter lesions in Japanese type 2 diabetic patientsEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 7 2010Futoshi Anan Eur J Clin Invest 2010; 40 (7): 585,590 Abstract Background, The presence of white matter lesions (WML) is an important prognostic factor for the development of stroke. Elevated hepatocyte growth factor (HGF) levels are associated with a high mortality rate in type 2 diabetic patients. The preliminary study was therefore designed to test the hypothesis that the presence of WML correlates with HGF and insulin resistance in type 2 diabetic patients not receiving insulin treatment. Material and methods, Based on brain magnetic resonance imaging, 92 type 2 diabetic patients were divided into two groups: WML-positive group (age 60 ± 5 years, mean ± SD, n = 35) and WML-negative group (age 59 ± 6 years, mean ± SD, n = 57. The level of blood glucose was assessed by fasting plasma glucose, fasting immunoreactive insulin, homeostasis model assessment (HOMA) index and haemoglobin A1c (HbA1c). Results, The body mass index was higher in the WML-positive group than that in the WML-negative group (P < 0·005). Plasma levels of triglycerides were higher while high-density lipoprotein cholesterol was lower in the WML-positive group than in the WML-negative group (P < 0·01 and P < 0·0001 respectively). Fasting plasma glucose (P < 0·0001), insulin concentrations (P < 0·0001), HOMA index (P < 0·0001) and HGF (< 0·0001) levels were higher in the WML-positive group than in the WML-negative group. Multivariate logistic analysis revealed that WML was independently predicted by the high HGF and insulin resistance (P < 0·0001 and P < 0·0001 respectively). Conclusion, The results of this preliminary study indicate that the presence of WML was associated with the high HGF and insulin resistance in Japanese patients with type 2 diabetes mellitus. [source] High HDL-cholesterol in women with rheumatoid arthritis on low-dose glucocorticoid therapyEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 9 2008C. García-Gómez ABSTRACT Background, Dyslipidaemia has been described in non-treated rheumatoid arthritis (RA), and improves after therapy with disease modifying anti-rheumatic drugs or glucocorticoids; however, it has generally been perceived that glucocorticoids adversely affect lipid metabolism. The association of low dose glucocorticoid therapy with plasma lipid levels was evaluated in female RA patients. Materials and methods, A cross-sectional study was conducted in 78 female RA patients [mean age: 60 (12) years; mean disease duration: 13 (9) years]. Sixty-five (83%) were on glucocorticoid therapy [total equivalent mean prednisone dose: 5·1 (1·7) mg d,1]. Each patient was assessed through a self-reported questionnaire, structured interview and physical examination. Blood samples were obtained for routine biochemistry, lipid profile and haematological tests. Lipid profiles of RA patients who were and were not on glucocorticoid therapy were compared. Results, Clinical and laboratory features of the two groups of patients were similar, except for the Health Assessment Questionnaire and body mass index, which were significantly higher in the patients on glucocorticoid therapy. These patients had 14·7% higher serum high-density lipoprotein cholesterol (HDL-c) levels than untreated patients (P = 0·043), mainly at the expense of HDL2 subfraction, which was 24·4% higher (P < 0·039), whereas HDL3-c was only 7·4% higher (P = 0·219). Serum levels of glucose and total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL -c), very low-density lipoprotein cholesterol, apolipoproteins A-I and B were not increased in patients on glucocorticoid therapy. Conclusions, Low dose glucocorticoid therapy in RA patients is associated with an increase in HDL-c, without increasing LDL-c or triglyceride. These lipid changes may overall be considered favourable. [source] High-density lipoprotein cholesterol, C-reactive protein, and prevalence and severity of coronary artery disease in 5641 consecutive patients undergoing coronary angiographyEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 6 2008H. F. Alber ABSTRACT Background, Although high-density lipoprotein cholesterol (HDL-C) and C-reactive protein (CRP) are well-established predictors for future cardiovascular events, little information is available regarding their correlation with the prevalence and severity of angiographically evaluated coronary artery disease (CAD). Material and methods,, Five thousand six hundred forty-one consecutive patients undergoing coronary angiography for the evaluation of CAD were analysed. Cardiovascular risk factors were assessed by routine blood chemistry and questionnaire. CAD severity was graded by visual estimation of lumen diameter stenosis with significant stenoses defined as lumen diameter reduction of , 70%. Coronary angiograms were graded as one-, two- or three-vessel disease, as nonsignificant CAD (lumen irregularities < 70%) or non-CAD. Results,, HDL-C (60·3 ± 18·5 vs. 51·9 ± 15·3 mg dL,1; P < 0·001) was higher and CRP was lower (0·65 ± 1·68 vs. 1·02 ± 2·38 mg dL,1; P < 0·001) in non-CAD (n = 1517) compared to overall CAD patients (n = 4124). CAD patients were older (65·2 ± 10·5 years vs. 59·9 ± 11·4 years), more often diabetics (19·2% vs. 10·6%) and hypertensives (79·2% vs. 66·0%) and included more smokers (18·8% vs. 16·5%) (all P < 0·005). Low-density lipoprotein cholesterol (124·5 ± 38·3 vs. 126·0 ± 36·3 mg dL,1; P = NS) was similar in overall CAD and non-CAD patients with more statin users (43·4% vs. 27·9%; P < 0·001) among CAD patients. Comparing non-CAD with different CAD severities using analysis of variance, results did not change substantially. In a multivariate analysis, HDL-C and CRP remained independently associated with the prevalence of CAD. In addition, HDL-C is also a potent predictor for the severity of CAD. Conclusions,, In this large consecutive patient cohort, HDL-C and CRP are independently associated with the prevalence of CAD. In this analysis, HDL-C is an even stronger predictor for CAD than some other major classical risk factors. [source] Genetic influence in antithrombotic actions of atorvastatin in hypercholesterolaemiaEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 1 2008L. Puccetti ABSTRACT Background, Recent data indicate that statins could offer coronary artery disease (CAD) benefit even by mechanisms beyond lipid lowering. Genetic influence has been shown for some antithrombotic actions of statins via oxidized-low-density lipoprotein cholesterol (ox-LDL) receptors and nitric oxide synthase (NOS) activity modulation. The present study was designed to evaluate the influence of ox-LDL lectin-like receptor-1 (LOX-1) and NOS polymorphisms in the incidence of cardiovascular events in pure hypercholesterolaemic subjects during statin treatment. Materials and methods, A prospective 4-year study involving 1039 event-free subjects (643 males, 396 females) treated with atorvastatin (10,40 mg day,1) to reach the appropriate Adult Treatment Panel-III LDL target of 3·36 mmol L,1. Enrolled subjects were evaluated every 6 months or at a clinical event. LOX-1 3,UTR/T-C and NOS G894T polymorphisms were detected by allelic discrimination assays (polymerase chain reaction), lipid profile by enzymatic-colorimetric method, ox-LDL by enzyme linked immunosorbent assay, platelet activation by P-selectin (P-sel) expression (FACScan), NOS activity (by intracellular citrullin recovery) and homocysteine (high performance liquid chromatography), C-reactive protein (CRP) by sensitive nephelometric technique. Results, LOX-1 3,UTR/T showed the strongest association with events in the whole cohort with respect to each other variable including LDL reduction and NOS G894T (OR 4·90, 95% CI 3·19,6·98, P < 0·00001). Smoking influenced events in LDL-targeted subjects (P < 0·0001). Ox-LDL and P-sel were better indicators than LDL or other variables according to 3,UTR/C genotype regardless of the magnitude of LDL reduction (OR 4·21, 95% CI 2·29,6·70 P < 0·0001). Conclusions, LOX-1 polymorphisms could influence statin effectiveness in CAD prevention by induction of sensitivity to antithrombotic mechanisms such as antiplatelet activity. [source] Preliminary report on effects of oxcarbazepine-treatment on serum lipid levels in childrenEUROPEAN JOURNAL OF NEUROLOGY, Issue 12 2006E. Franzoni The aim of the present study was to assess serum lipid levels before and after treatment with oxcarbazepine (OXC) in children with epilepsy. We measured total cholesterol (TC), triglycerides (TGs) and high-density lipoprotein cholesterol (HDL-C) in 28 patients whereas only TC levels in 11 patients, during baseline period and at 3 months after the beginning of therapy with OXC. During baseline period, median values were: 4.38 mmol/l (IQR = 4.12,5.03) for TC levels, 1.72 mmol/l (IQR = 1.42,2.01) for HDL-C levels and 1.54 mmol/l (IQR = 1.29,1.96) for TGs levels. At 3 months, median values were: 4.38 mmol/l (4.10,4.95) for TC levels (P < 0.05), 1.57 mmol/l (1.34,1.93) for HDL-C levels (P < 0.005) and 1.8 mmol/l (1.23,2.34) for TGs levels (P < 0.05). Median serum lipid levels remained in the normal range, despite an increasing-trend at 3 months of treatment with OXC. Further studies are necessary to confirm these results. [source] Induction of endogenous pathways by antiepileptics and clinical implicationsFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 5 2005M. Strolin Benedetti Abstract The aim of this study was to review modifications of the endogenous pathways (e.g. enzyme elevations, normal body constituent depletion or higher formation/excretion of endogenous metabolites) which could be ascribed to enzyme induction by antiepileptic drugs (AEDs). Information on older (e.g. phenobarbital, phenytoin and carbamazepine) and newer drugs (where information is available) is discussed together with clinical implications. The enzymes involved in the endogenous pathways and induced by the AEDs will not be limited to the hepatic microsomal enzymes; extrahepatic enzymes and/or enzymes present in other subcellular fractions will also be discussed, if pertinent. The induction of endogenous pathways by AEDs has been taken into account in the past, but much less emphasis has been given compared with the extensive literature on induction by AEDs of the metabolism of concomitantly administered drugs, either of the same or of different classes. Not all of the endogenous pathways examined and induced by AEDs appear to result in serious clinical consequences (e.g. induction of hepatic ALP, increased excretion of d -glucaric acid or of 6, -hydroxycortisol). In some cases, induction of some pathways (e.g. increase of high-density lipoprotein cholesterol or of conjugated bilirubin) might even be a beneficial side-effect, however enzyme induction is considered rather a detrimental aspect for an AED, as induction is generally a broad and a non-specific phenomenon. The new AEDs have generally less induction potential than the older agents. Yet some (felbamate, topiramate, oxcarbazepine and lamotrigine) have the potential for inducing enzymes, whereas others (levetiracetam, gabapentin and vigabatrin) appear to be completely devoid of enzyme inducing characteristics, at least as far as the enzymes investigated are concerned. [source] Cardiovascular Risk Factors in Subjects with Helicobacter pylori InfectionHELICOBACTER, Issue 2 2002Toshiharu Takashima Abstract Background. It has been proposed that Helicobacter pylori infection is related to cardiovascular disease, although this has not been fully investigated. The aim of this study was to investigate whether H. pylori in-fection is associated with cardiovascular risk factors. Subjects and Methods. One thousand six hundred and fifty people undergoing annual medical checks at Shimane Institute of Health Science between September 1998 and August 1999 were enrolled. Gender, age, body mass index, habitual smoking and drinking, systolic and diastolic blood pressure, serum level of total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDLC), blood glucose, leukocyte count and hemoglobin were compared between H. pylori seropositive and seronegative cases. Results. In H. pylori seropositive individuals, HDLC was significantly lower than that in seronegative individuals. After adjustment for possible confounding factors (gender, age, BMI, smoking and drinking habits), mean HDLC in H. pylori -seropositive and seronegative individuals were 56.1 and 58.2 mg/dl, respectively (p < .005). The percentage of the elderly (over 50 years old) individuals with HDLC < 35 mg/dl in H. pylori seropositive and seronegative groups were 7.4% and 4.7%, respectively (p < .001). In addition, the lower HDLC level was accompanied by an increased leukocyte count. Conclusion. Long-term infection with H. pylori may have an important role in decreasing the serum HDLC concentration. [source] Efficacy of ezetimibe for the treatment of non-alcoholic steatohepatitis: An open-label, pilot studyHEPATOLOGY RESEARCH, Issue 6 2010Masato Yoneda Aim:, Non-alcoholic steatohepatitis (NASH) is considered a hepatic manifestation of metabolic syndrome. However, effective drug therapy for NASH has not been established yet. In the present study, we evaluated the efficacy of 6 months of ezetimibe treatment for NASH patients with dyslipidemia for the comparison of improvement of the clinical parameters and histological alterations. Methods:, We prospectively evaluated 10 consecutive NASH patients with dyslipidemia who agreed to participate in this study. The patients were given ezetimibe (10 mg/day) for 6 months, and clinical parameters and histological alterations were comparatively evaluated before and after treatment. All the patients were given standard calorie diet (30 kcal/kg per day, carbohydrate 50,60%, fat 20,30%, protein 15,20%) and exercise counseling from 3 months before the ezetimibe treatment. Results:, The serum aspartate aminotransferase, alanine aminotransferase, ,-glutamyl transpeptidase, low-density lipoprotein cholesterol, high-sensitivity C-reactive protein and type IV collagen 7 s levels were significantly improved by the treatment with ezetimibe for 6 months. In histological observations, follow-up liver biopsies revealed that the NAS score and steatosis grade were also significantly improved. The fibrosis stage did not change significantly, but six of the 10 patients exhibited an improvement in their fibrosis stage. Conclusion:, Major clinical parameters and histological observations were significantly improved by the treatment with ezetimibe. Our pilot study demonstrated the efficacy of ezetimibe for drug therapy of NASH and may lead to a large-scale clinical trial in the future. [source] Effect of simplification from protease inhibitors to boosted atazanavir-based regimens in real-life conditionsHIV MEDICINE, Issue 9 2010R Rubio Background Atazanavir (ATV) boosted with ritonavir (ATV/r) is a potent, well-tolerated, once-daily protease inhibitor (PI). Few data are available on this agent as a treatment simplification option for patients taking other PIs. Objective The aim of the study was to determine the effectiveness and safety of ATV-containing regimens in patients who have simplified their antiretroviral treatment. Methods SIMPATAZ was a multicentre, prospective, noninterventional study in patients who had undetectable HIV RNA on their current PI-containing therapy and who were switched to an ATV/r-based regimen. Patients underwent a routine physical examination, and data were collected on HIV RNA levels, CD4 cell counts, liver function, lipid parameters, adverse reactions, adherence to treatment and patient satisfaction. Results A total of 183 patients were enrolled in the study and included in the analysis (80% were male, 29% had AIDS, and 52% were coinfected with HIV and hepatitis B virus or hepatitis C virus). The median baseline CD4 count was 514 cells/,L. Median exposure to previous HIV therapy was 8 years, and 32% of patients had a history of PI failures. Lopinavir boosted with ritonavir was the most frequent PI replaced (62%) and tenofovir+lamivudine /emtricitabine the backbone most used during the study (29%). The study drug was discontinued early by 25 patients (14%), two of whom discontinued as a result of adverse events (Hodgkin lymphoma and vomiting). Two patients died (lung cancer and myocardial infarction). At month 12, 93% of the study population had an undetectable HIV RNA viral load. Hyperbilirubinaemia >3 mg/dL and increased alanine aminotransferase levels>200 IU/L were observed in 38.5% and 4.4% of patients, respectively. Median changes from baseline to month 12 in total cholesterol, triglycerides and low-density lipoprotein cholesterol were ,13 mg/dL (,7%; P<0.0001), ,19 mg/dL (,13%; P<0.0001) and ,7 mg/dL (,6%; P=0.021), respectively. Conclusions In a real-world setting, switching from other PIs to ATV/r is a well-tolerated and safe option for improving the lipid profile and for retaining virological response in controlled pretreated patients.
