Background: Obesity is a risk factor for renal damage. This study aimed to determine the relationship between body fat percent and creatinine clearance in adult patients with and without type 2 diabetes mellitus (T2DM). Methods: An observational prospective cross-correlation study was carried out among adults with and without T2DM between 18 and 60 years of age. It was determined the time of evolution with T2DM, as well as fat percentage (FP), body mass index (BMI), creatinine clearance (Cockroft-Gault [CrCCG]), glycemia and micro/macroalbuminuria. The correlation between CrCCG and FP was determined by Spearman's test. Results: 174 subjects were included in this study. Obesity by BMI and FP in subjects with and without T2DM was similar. Of the studied subjects, 12.6 % didn't have kidney damage and 50.7 % had increased risk of renal disease; the frequencies for stages 1-4 of kidney damage were 12.0, 20.1, 4.0 and 0.6 %, respectively. Spearman's test showed a direct relationship between FP and CrCCG, higher in diabetics (r = 0.418, p < 0.0001) than in non-diabetics (p = 0.327, p < 0.0001). Conclusions: The FP was correlated directly with the CrCCG in subjects with and without T2DM; therefore, we can conclude that the greater the kidney damage, the smaller the fat porcentage in the study sample.

Objective: to know the relationship between total body composition and the stage of kidney damage, according to the K/DOQI classification, in patients with type 2 diabetes mellitus (T2DM). Methods: under a correlation design, adults with T2DM were studied. Age, evolution time, fat and lean mass, fat percentage, total water, body index mass (BMI), creatinine clearance by Cockroft-Gault (CrCCG), glucose, HbA1c, proteinuria and microalbumin-uria were determined. T test to compare independent means and Spearman correlation were used. Results: the study included 60 men (23.4%) and 196 women (76.6%). There were no differences by gender when comparing age, BMI, duration of T2DM, blood glucose and HbA1c. The analysis showed a direct relationship between BMI (r= 0.281), the amount of fat mass (r = 0.360), lean tissue (r = 0.158), and water (r= 0.176) with the CrCCG (p < 0.0001). The biggest change in body composition, due to fat mass, was observed in chronic kidney disease stages 1-3, in which BMI had a good correlation with fat mass (r = 0.80, p < 0.001). Conclusions: fat mass is inversely related to the stage of kidney damage in patients with T2DM. [ABSTRACT FROM AUTHOR]

Background: The estimate for metabolic syndrome (MS) worldwide is above 20%; MS it has been linked to urolithiasis., Objective: To determine the association between the components of MS as risk factors for urolithiasis in the adult population of Yucatán, Mexico., Method: Case-control study with a sample size of 85 subjects per group, paired by age and sex; patients with urolithiasis (stones > 5 mm) and controls without urolithiasis. Diagnosis was verified by ultrasound. Blood pressure, weight, height, waist circumference, serum triglycerides, HDL cholesterol, glycemia, and urinalysis were determined. International Diabetes Federation criteria were used for the MS diagnosis. Subjects with kidney damage, endocrinopathies and consumption of steroid drugs were excluded. Descriptive statistics, association analysis and risk calculation were performed., Results: One hundred and seventy subjects were included, 83.5% were women and 52.4% presented MS. Was observed an association between urolithiasis and MS (odds ratio [OR]: 2.7; 95% confidence interval [95% CI]: 1.4-5.1; p = 0.001), hypertriglyceridemia (OR: 1.9; 95% CI: 1.06-3.66; p = 0.021) and high blood pressure (OR: 2.5; 95% CI: 1.2-4.8; p = 0.004). The analysis showed that a higher quantity of MS components increases the risk of urolithiasis (p = 0.004)., Conclusions: MS increased in 2.7-fold the risk of urolithiasis. Hypertriglyceridemia and high blood pressure are MS components that increased the risk of urolithiasis., (Copyright: © 2020 Revista Medica del Instituto Mexicano del Seguro Social.)
