Prevalence and determinants of the metabolic syndrome among subjects with advanced nondiabetes-related chronic kidney disease in Gran Canaria, Spain.

BACKGROUND: The relationship between the metabolic syndrome and mild chronic kidney disease (CKD) has been extensively studied. This study was aimed to estimate the prevalence and factors associated with the metabolic syndrome among subjects with advanced stages of nondiabetes-related CKD. METHODS: Study population was composed of incident patients with advanced CKD not related to diabetes in a tertiary hospital from Gran Canaria (Spain) since February 2011 to December 2014. Participants fulfilled a survey questionnaire and underwent physical examination and biochemical evaluation. RESULTS: The sample was composed of 167 subjects (mean age 63.9 ± 13.7 years; estimated glomerular filtration rate 21.9 ± 6.6 mL/min/1.73 m(2)). The prevalence of the metabolic syndrome was 68.9% (65.2% in men and 73.3% in women). Highest rates were observed in groups with chronic interstitial nephropathy (80%), CKD of uncertain etiology (76.7%) and CKD related to vascular causes (76.2%). Subjects with metabolic syndrome were older, had higher values of C-reactive protein and more often reported to have first-degree relatives with diabetes and to be physically inactive. In multivariate analyses, age (OR: 1.034 [CI 95%: 1.004-1.065]; p = 0.024) and family history of diabetes (OR: 2.550 [1.159-5.608]; p = 0.020) were independently associated with the metabolic syndrome. CONCLUSIONS: The prevalence of the metabolic syndrome among subjects with advanced nondiabetes-related CKD is high, and greater than that observed in general Canarian population of similar age groups. Age and family history of diabetes are the two factors more strongly associated with the metabolic syndrome in this population.

The specific relationship between vitamin D deficiency and diabetic nephropathy among patients with advanced chronic kidney disease: a cross-sectional study in Gran Canaria, Spain.

AIMS: Vitamin D deficiency is highly prevalent in subjects with advanced chronic kidney disease (CKD), but diabetes, the most common cause of CKD, has also been linked to low levels of serum 25-hydroxyvitamin D [25(OH)D]. We compare vitamin D status between subjects with type 2 diabetes-related advanced CKD and subjects with either advanced CKD without diabetes or type 2 diabetes without advanced CKD. METHODS: Subjects were patients with advanced CKD (estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m2) from February 2011 to November 2013 (113 with diabetes-related CKD and 80 without diabetes) and 61 patients with long-lasting type 2 diabetes without advanced CKD, simultaneously enrolled from our center. Participants fulfilled a survey questionnaire and underwent physical examination, blood samples, and 24-h urine collection. Kidney disease was assessed using eGFR and 24-h urinary protein excretion. Serum 25(OH)D was measured by chemiluminescence immunoassay. RESULTS: The prevalence of vitamin D deficiency (25(OH)D < 20 ng/mL) was 70.8% in subjects with diabetes-related CKD, 38.8% in subjects with non-diabetic CKD and 41% in subjects with diabetes without advanced CKD. Adjusted means (95% confidence interval (CI)) of 25(OH)D in participants with diabetes-related CKD, in nondiabetic participants with CKD, and in participants with diabetes without advanced CKD were, respectively, 17.5 (14.2 - 20.7), 23.6 (19.4 - 27.8), and 23.5 (16.8 - 30.3) ng/mL (p = 0.023). CONCLUSIONS: Low vitamin D status is characteristically associated with advanced diabetic nephropathy. This relationship is not entirely attributable to the individual effects of CKD or long-lasting diabetes.

Potential implications of the choice among three alternative treatment targets for apolipoprotein B100 in the management of patients with type 2 diabetes and chronic kidney disease.

This study analyses discordance rates between attainment of therapeutic goals for apolipoprotein B100 (apoB) and both low-density lipoprotein-cholesterol (LDL-C) and non-high-density lipoprotein-cholesterol (non-HDL-C) in a sample of 152 patients with type 2 diabetes and chronic kidney disease from Gran Canaria (Spain), using treatment targets recommended by the American Diabetes Association/American College of Cardiology (ADA/ACC), the European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) and by a Spanish population-based study. Among subjects with LDL-C levels at therapeutic goal, apoB was above target in 16.3% (ADA/ACC), 6.5% (ESC/EAS) and 39.1% (population-based criteria), and among subjects with non-HDL-C levels at therapeutic goal, apoB was above target in 10.5% (ADA/ACC), 1.2% (ESC/EAS) and 29.6% (population-based criteria). These findings show that clinical management would be very differently altered depending on the criteria used to set treatment targets for apoB. Cut-off points derived from population data identify a greater number of subjects suitable for a more intensive lipid-lowering therapy.

Non-albuminuric renal disease among subjects with advanced stages of chronic kidney failure related to type 2 diabetes mellitus.

Urinary albumin excretion has been consistently found to be normal in a significant number of subjects with early stages of diabetic kidney disease. This study was aimed to estimate the prevalence and characteristics of non-albuminuric chronic kidney disease associated with type 2 diabetes mellitus among subjects who reach advanced stages of renal failure. Study population was composed of incident patients with advanced chronic kidney disease (glomerular filtration rate <30 mL/min) related to type 2 diabetes in a tertiary hospital from Gran Canaria (Spain) during a period of 2 years. Subjects were classified as normoalbuminuric (urinary albumin-to-creatine ratio [UACR] <30 mg/g), microalbuminuric (UACR ≥30 and <300 mg/g), or proteinuric (UACR ≥300 mg/g). Of 78 eligible patients, 21.8% had normoalbuminuria, 20.5% had microalbuminuria, and 57.7% had proteinuria. Individuals with normoalbuminuria were mostly women and had a lower prevalence of smoking and polyneuropathy than subjects with microalbuminuria or proteinuria. They also presented greater measures of body mass index and waist circumference, higher values of total and LDL cholesterol, and lower values of HbA1c and serum creatinine than subjects with microalbuminuria or proteinuria. Multivariate analysis demonstrated that female sex (positively) and HbA1c and polyneuropathy (negatively) were independently associated with absence of albuminuria. In conclusion, around 20% of subjects with diabetes-related advanced chronic kidney disease, characteristically women, have normal urinary albumin excretion. HbA1c and polyneuropathy are inversely related to this non-albuminuric form of nephropathy.

Metabolic syndrome in Argentine women: ATPIII, IDF, IDF/AHA/NHLBI; what criterion should be used?

INTRODUCTION: The menopause and the metabolic syndrome (MS) are related with the increase of the risk of cardiovascular diseases. OBJECTIVES: To evaluate the existence of metabolic risk factors and the prevalence of MS in pre- and post-menopausal women. SUBJECTS: 253 women: 120 pre-menopausal and 133 post-menopausal. Anthropometric, arterial pressure and waist circumference measurements were carried out. Glycaemia, lipids, creatinine, hepatogram, uric acid and thyroid-stimulating hormone were dosed. RESULTS: Statistical higher registries of arterial pressure, levels of glycaemia, total cholesterol, low-density lipoprotein, triglycerides and TG/high-density lipoprotein relation were observed among post-menopausal patients. As regards this group, the MS diagnosis was considerably higher, being the same by all the criteria. CONCLUSIONS: We found more prevalence of cardiometabolic and MS risk factors among the group of post-menopausal patients. The responsible mechanisms would respond to the secondary hypoestrogenaemia at the cease of the ovarian function. Because of this fact, menopausal women should be considered a risk group for the development of MS.
