AbstractBackgroundAdiponectin secreted by adipocytes plays a key role in insulin sensitivity, anti-inflammation, and antiatherosclerosis. It is involved in several conditions including obesity, type 2 diabetes mellitus, cardiovascular disease, and chronic kidney disease (CKD). Glomerular filtration rate is monitored to indicate the kidney function and CKD progression.ObjectiveTo assess the serum adiponectin levels in individuals with normal and mildly decreased glomerular filtration rate, analyze the association of serum adiponectin with various physical and biological parameters, and test whether serum adiponectin is the risk factor of mildly decreased glomerular filtration rate.MethodsThis cross-sectional study was conducted in 172 individuals with 35–60 years of age. Serum samples were collected and divided into two groups, based on estimated glomerular filtration rate (eGFR): 90 with normal eGFR (G1, eGFR ≥90 mL/min/1.73 m2) and 82 with mildly decreased eGFR (G2, eGFR = 60–89 mL/min/1.73 m2). Anthropometric data were recorded. Serum adiponectin was measured by enzyme-linked immunosorbent assay.ResultsSerum adiponectin levels were significantly increased in individuals with mildly decreased eGFR (G2), compared to G1 (8.23 ± 3.26 µg/mL and 6.57 ± 3.24 µg/mL, respectively; P = 0.001). Serum adiponectin was positively associated with age and high-density lipoprotein cholesterol but negatively associated with weight, body mass index, triglyceride, and waist and hip circumferences. Univariate analysis showed that serum adiponectin was significantly correlated with mildly decreased eGFR; however, when adjusting for confounding factors, there were no correlations. Furthermore, multivariate regression analysis showed that individuals at the age of 46–55 years (4.0; 95% CI: 1.9–8.3) and > 55 years (11.4; 95% CI: 3.7–35.5) were significantly correlated with mildly decreased eGFR.ConclusionsSerum adiponectin was significantly elevated in individuals with mildly decreased eGFR and may be a modulation factor, but was not an independent risk factor for mildly kidney damage. Further study is needed to clarify its potential benefits as monitoring biomarker for CKD progression.

Energy intake and renal function decrease with age. In patients with chronic kidney disease (CKD), spontaneous food intake decreases in parallel with the loss of renal function. The objective of the present study was to evaluate a possible relationship between renal dysfunction and energy intake in elderly community-dwelling men. A cross-sectional study including 1087 men aged 70 years from the Uppsala Longitudinal Study of Adult Men (ULSAM) community-based cohort was carried out. Dietary intake was assessed using 7 d food records, and glomerular filtration rate was estimated from serum cystatin C concentrations. Energy intake was normalised by ideal body weight, and macronutrient intake was energy-adjusted. The median normalised daily energy intake was 105 (interquartile range 88–124) kJ, and directly correlated with estimated glomerular filtration rate (eGFR) as determined by univariate analysis. Across the decreasing quartiles of eGFR, a significant trend of decreasing normalised energy intake was observed (P =0·01). A multivariable regression model including lifestyle factors and co-morbidities was used for predicting total energy intake. In this model, regular physical activity (standardised β = 0·160; P =0·008), smoking (standardised β = − 0·081; P =0·008), hypertension (standardised β = − 0·097; P =0·002), hyperlipidaemia (standardised β = − 0·064; P =0·037) and eGFR (per sd increase, standardised β = 0·064; P =0·04) were found to be independent predictors of energy intake. Individuals with manifest CKD (eGFR < 60 ml/min per 1·73 m2) were more likely to have lower energy intake than those without. In conclusion, there was a direct and independent correlation between renal function and energy intake in a population-based cohort of elderly men. We speculate on a possible link between renal dysfunction and malnutrition in the elderly.

Abstract Objective: To describe the frequency of albuminuria in overweight and obese children and adolescents and to relate it to the severity of obesity, pubertal staging, associated morbidities and the glomerular filtration rate. Method: Cross-sectional study including 64 overweight and obese children and adolescents between 5 and 19 years of age. Data collected: weight, height, waist circumference and systemic arterial pressure. Laboratory tests: lipid profile; glycemia and insulin, used to calculate the Homeostasis Model Assessment (HOMA-IR); C-reactive protein; glutamic-pyruvic transaminase and albuminuria in an isolated urine sample (cutoff <30 mg/g). Creatinine was used to calculate the estimated glomerular filtration rate (eGFR, mL/min/1.73 m2). Results: The mean age was 11.6 ± 3.4 years, 32 (50%) and 29 (45.3%) were male and prepubertal. Forty-six (71.9%) had severe obesity. The frequency and median (min/max) of the observed values for albuminuria (> 30 mg/g) were 14 (21.9%) and 9.4 mg/g (0.70, -300.7 mg/g). The mean eGFR was 122.9 ± 24.7 mL/min/1.73 m2. There was no significant correlation between body mass index, pubertal staging, insulin and HOMA-IR with albuminuria values and neither with eGFR. Children with albuminuria tended to have higher values of diastolic blood pressure (75.0 ± 12.2 vs. 68.1 ± 12.4, p = 0.071). Conclusion: Albuminuria, although frequent in children and adolescents with obesity, was not associated with other morbidities and the glomerular filtration rate in these patients.

Background: Kidney disease is more common in people of African descent in developed countries. Studies reporting estimate Glomerular Filtration Rate (eGFR) in African populations and people living with HIV have been carried more frequently on adults than children. The study aimed to assess eGFR by use of the SCHWARTZ formula in HIV infected children seen at tertiary hospital.Methods: A descriptive, prospective and cross sectional study of 221 children with HIV infection. Schwartz formula was used to determine eGFR. The main outcome measures were eGFR. The study population comprised HIV infected children attending Paediatric out-patients’ clinic and those admitted into the Paediatric wards, aged between 6 months and 15 years. Data was analysed using SPSS version 20 and results presented in tables and figures. Results: The age range of the study subjects was 12 months to 15 years with the mean age and SD of 8.21±3.61 years. There were 129 (58.4%) male and 92 (41.6%) female children with male to female ratio 1: 0.7.  The mean age for males was 7.87±3.49 years while that for females was 8.70±3.71 years. The eGFR for the study as determined by Schwartz formula had a range of 49.21 to 463.67 ml/ min/ 1.73m2 with the mean of 159.56±59.04 ml/min. The mean eGFR for the males and females were 166.39±63.54ml/ min and 149.99±45.01 ml/ min respectively. Conclusion: The study, in comparison with other studies, observed a lower prevalence of CKD in HIV infected children. Detection of CKD in HIV infection children may be more optimal if combined methods are employed.

Abstract Background Urinary 20-hydroxyeicosatetraenoic acid (20-HETE) has been associated with hypertension in women with elevated urinary cadmium (Cd) excretion rates. The present study investigates the urinary Cd and 20-HETE levels in relation to the estimated glomerular filtration rate (eGFR) and albumin excretion in men and women. Methods A population-based, cross-sectional study, which included 225 women and 84 men aged 33–55 years, was conducted in a rural area known to be polluted with Cd. Results In all subjects, lower eGFR values were associated with higher urinary Cd excretion (P = 0.030), and tubulopathy markers N-acetyl-β-d-glucosaminidase (P < 0.001) and β2-microglobulin (β2-MG) (P < 0.001). On average, the hypertensive subjects with the highest quartile of urinary Cd had eGFR values of 12 and 17 mL/min/1.73 m2 lower than that in the hypertensive (P = 0.009) and normotensive subjects (P < 0.001) with the lowest quartile of urinary Cd, respectively. In men, urinary albumin was inversely associated with 20-HETE (β = −0.384, P < 0.001), while showing a moderately positive association with systolic blood pressure (SBP) (β = 0.302, P = 0.037). In women, urinary albumin was not associated with 20-HETE (P = 0.776), but was associated with tubulopathy, reflected by elevated urinary excretion of β2-MG (β = 0.231, P = 0.002). Conclusions Tubulopathy is a determinant of albumin excretion in women, while 20-HETE and SBP are determinants of urinary albumin excretion in men. Associations of chronic exposure to Cd with marked eGFR decline and renal tubular injury seen in both Cd-exposed men and women add to mounting research data that links Cd to the risk of developing chronic kidney disease.
