Tangled relationship between insulin resistance and microalbuminuria in children with obesity. World J Clin Pediatr 2022; 11:455-462. [PMID: 36439903 PMCID: PMC9685682 DOI: 10.5409/wjcp.v11.i6.455] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 09/19/2022] [Accepted: 10/28/2022] [Indexed: 11/07/2022] Open
Abstract
Childhood obesity represents a complex disease with a well-known cardiometabolic burden including fatty liver, type 2 diabetes, metabolic syndrome, and cardiovascular disease. From a pathogenic point of view, insulin resistance (IR) represents the key factor underlying the spectrum of these obesity consequences. As observed in adults, recent data supported the occurrence of microalbuminuria (MA) as marker of early kidney dysfunction and its potential link with cardiometabolic factors also in children with obesity. In fact, a well-documented pathophysiological hypothesis both in adults and children supported an intimate correlation with the major feature of obesity such as IR through the influence of insulin on renal hemodynamics. Based on the clinical and prognostic relevance of this relationship in daily practice (including an increased risk of chronic kidney disease development overtime), more scientific attention needs to be paid to the evaluation of early kidney damage in children with obesity. In this paper, we attempt to address three debated questions regarding the intriguing liaison between IR and MA in children with obesity: (1) What is the prevalence of pediatric MA? (2) What is the state of art of MA in children with obesity? and (3) Is there a link between IR and MA in children with obesity?

Effect of Bariatric Surgery on Albuminuria in Non-Diabetic Non-Hypertensive Patients with Severe Obesity: a Short-Term Outcome. Obes Surg 2022; 32:2397-2402. [PMID: 35524905 PMCID: PMC9276579 DOI: 10.1007/s11695-022-06091-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 04/16/2022] [Accepted: 04/26/2022] [Indexed: 11/23/2022]
Abstract
Background Obesity is a risk factor for chronic kidney disease and albuminuria. Despite the well-documented obesity association with diabetes mellitus and hypertension, its predisposition to albuminuria is not related to these comorbidities, and, in some times, its occurrence is independent of DM or hypertension. Purpose of the study The present study aimed to evaluate bariatric surgery effect on albuminuria in patients with severe obesity with no DM or hypertension. Materials and methods The study consisted of 137 patients with extreme obesity and albuminuria scheduled for bariatric surgery and did not have diabetes or hypertension. They underwent an assessment for 24-h urinary albumin at baseline (T0) and 6 months postoperatively (T2). Results Albuminuria remission occurred in 83% of patients; there was a statistically highly significant difference between the baseline and the 6-month postoperative in the 24-h urinary albumin assessment. Weight loss and BMI at T2 were independent predictors of albuminuria remission. Conclusion The current work emphasizes the importance and promising role of bariatric surgery as an effective weight reduction management method in improving albuminuria, an early sign of chronic kidney disease, and a potential risk factor for cardiovascular disease.

Abstract
Adolescent obesity and CKD are both significant public health issues independently. When seen as comorbid conditions, they can cause deleterious health outcomes that put them on the fast track to necessitate dialysis or transplantation. This paper analyzes the effects of various biomarkers and comorbidities seen in the intersection of obesity and CKD in the adolescent population. We illustrate the estimated prevalence of these biomarkers and comorbidities through a review of the literature, available treatment, and obesity-related glomerulopathies. We found significant prevalence of the biomarkers, microalbuminuria (9.42% ± 9.31% and interquartile range [IQR] of 9.5%), hypertension (23.60% ± 22.5% and IQR of 9.5%), low high-density lipoprotein (14.34% ± 5.46% and IQR of 5%), hyperfiltration (3.12% ± 5.16% and IQR of 4%), and lower estimated glomerular filtration rate 4.59 ± 2.75 and IQR of 3%. Identification of prevalent biomarkers and their manifestations can serve to inform clinicians what to look for in daily setting and help elucidate the magnitude of this growing issue. Additionally, pertinent treatment options from pharmacotherapy to bariatric surgery are outlined to provide care providers with the full spectrum of treatment options for obesity in adolescent populations.

Abstract
BACKGROUND: Obesity has been reported to be a risk factor for chronic kidney disease and albuminuria. Obesity-related glomerulopathy (ORG) usually has a gradual onset, with microalbuminuria or clinically dominant proteinuria as the primary manifestation, with or without impaired renal function, and a small number of patients manifesting with microscopic hematuria or nephrotic syndrome.
AIM: The present study aimed to evaluate the prevalence of ORG in morbidly obese patients and its impact on renal function.
PATIENTS AND METHODS: This is a descriptive cross-sectional study that included patients with morbid obesity who visited the bariatric clinic in our institution during the period from October 2019 to February 2021. Patients who had no history of diabetes mellitus (DM) or hypertension underwent blood pressure measurement, assessment for 24-h urinary albumin to detect patients with laboratory-based ORG, kidney function tests, urine analysis and HbA1c, and examination by abdominal sonogram focused on both kidneys. Patients with asymptomatic micro or macroalbuminuria were recruited to the study.
RESULTS: The total number of patients screened during the study period was 1,045, out of whom 100 patients were eligible for the study according to the inclusion and exclusion criteria, denoting an albuminuria prevalence of 9.5% and there is no statistically significant relationship between this albuminuria and age, gender, and BMI.
CONCLUSION: ORG is a rising problem in the field of morbid obesity management, the current study shows that the prevalence of ORG is 9.5% in our screened cohort.

Abstract
UNLABELLED Because of the limitation of body mass index (BMI) in distinguishing adipose mass from muscle, the tri-ponderal mass index (TMI) has been proposed as a new indicator for better assessing adiposity in children and adolescents. However, it remains unclear whether TMI performs better than BMI or other adiposity indices in predicting obesity status in childhood and obesity-related cardiovascular risk factors (CVRFs) in childhood or adulthood. We searched PubMed, Cochrane Library, and Web of Science for eligible publications until June 15, 2021. A total of 32 eligible studies were included in this systematic review. We found that TMI had a similar or better ability to predict body fat among children and adolescents than BMI. However, most of the included studies suggested that TMI was similar to BMI in identifying metabolic syndrome although TMI was suggested to be a useful tool when used in combination with other indicators (e.g., BMI and waist circumference). In addition, limited evidence showed that TMI did not perform better than BMI for identifying specific CVRFs, including insulin resistance, high blood pressure, dyslipidemia, and inflammation in children and adolescents, as well as CVRFs in adults.

Abstract
OBJECTIVE Overweight/obesity has predicted cardiovascular disease (CVD) risk for long with its standard measure of body mass index (BMI), which later was found to mis-classify risk oftentimes. This is because it does not differentiate between fat and whole body mass. The finding that fat especially visceral fat was more culpable shifted attention to ectopic fat as a more precise measure of CVD risk. Peri-renal fat (PRF) is one such ectopic foci, which is hardly used despite the relative ease of assessment. We assessed PRF to correlate it with carotid intima media thickness (CIMT) to see if there was any significance in order to obviate need for heavy equipment in CVD risk assessment. METHODS This is secondary analysis of data generated in the course of studying sub-clinical atherosclerosis in apparently normal individuals. Subjects underwent routine anthropometry to determine BMI. They then underwent abdominal ultrasound studies wherein PRF was measured as the size of the echogenic strip between the posterior part of the liver and the right kidney. The CIMT was measured using the same equipment but a different transducer, as the distance between the intima and medial layers of the right common carotid artery 1 cm proximal to the carotid bulb. RESULTS The 221 subjects (82 M, 139 F) had mean ages of 37.01±10.97 and 36.86±11.62 years respectively. PRF correlated significantly with CIMT, age and all anthropometric measures. A PRF level of 0.26 cm turned out to be a significant value that determined presence of sub-clinical atherosclerosis deriving from the receiver operating characteristic curve analysis. CONCLUSION PRF has shown to be correlated significantly with indices that predict atherosclerosis. Being an ectopic fat focus, its local and systemic effects on the kidney increase systemic vascular resistance and CVD. Since it can easily be measured on abdominal ultrasound, a test readily available and requiring lower level skills it should be used to advantage. Levels above 0.26 cm should prompt initiation of curative or preventive action to control CVD in the population.

Abstract
BACKGROUND AND AIMS Our study sought to investigate the prevalence of moderately increased albuminuria in United Arab Emirates (UAE) nationals with type 2 diabetes, and to identify the associated factors. METHODS This prospective cross-sectional study was conducted in two hundred and seven UAE nationals with type 2 diabetes mellitus attending the internal medicine department of a secondary care hospital. Moderately increased albuminuria was estimated in random spot urine samples and was defined as urinary albumin-to-creatinine ratio (UACR) of 3-30 mg/mmoL. Prevalence and associations of moderately increased albuminuria were evaluated. RESULTS The study population had a mean UACR of 7.2 ± 10.2 mg/mmoL with mean eGFR of 94.5 ± 11.7 mL/min/1.73 m2. Prevalence of moderately increased albuminuria in our study population was found to be 44.0%. Multivariate logistic regression analysis showed that duration of diabetes (OR:1.72, 95% CI:1.34-2.19; p<0.001), presence of hypertension (OR:3.42, 95% CI:0.96-12.20; p=0.050) and neuropathy (OR:2.85, 95% CI:1.03-7.84; p=0.042), BMI (OR:1.08, 95% CI:1.01-1.16; p=0.019), HbA1c (OR:1.39, 95% CI:1.00-1.93; p=0.045), CRP (OR:1.10, 95% CI:1.00-1.22; p=0.035), serum creatinine (OR:1.04, 95% CI:1.02-1.06; p<0.001) and HDL-C (OR:0.10, 95% CI:0.01-0.28; p<0.001) were independently correlated with moderately increased albuminuria. Stepwise multiple linear regression analysis demonstrated that duration of diabetes, HbA1c, CRP and serum creatinine were independent predictors of UACR. CONCLUSION We report a high prevalence of moderately increased albuminuria in UAE nationals with type 2 diabetes in a secondary care setting. Routine screening and timely management of moderately increased albuminuria in type 2 diabetes mellitus can lead to better patient outcomes.

Abstract
BACKGROUND AND OBJECTIVES The association of AKI after pediatric cardiac surgery with long-term CKD and hypertension development is unclear. The study objectives were to determine whether AKI after pediatric cardiac surgery is associated with incident CKD and hypertension. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This was a prospective cohort study of children of 1 month to 18 years old who were undergoing cardiac surgery at two tertiary care centers (Canada, United States). Participants were recruited before cardiac surgery and were followed during hospitalization and at 3, 12, 24, 36, and 48 months after discharge. Exposures were postoperative AKI, based on the Kidney Disease Improving Global Outcomes (KDIGO) definition, and age <2 years old at surgery. Outcomes and measures were CKD (low eGFR or albuminuria for age) and hypertension (per the 2017 American Academy of Pediatrics guidelines) at follow-up, with the composite outcome of CKD or hypertension. RESULTS Among 124 participants, 57 (46%) developed AKI. AKI versus non-AKI participants had a median (interquartile range) age of 8 (4.8-40.8) versus 46 (6.0-158.4) months, respectively, and higher preoperative eGFR. From the 3- to 48-month follow-up, the cohort prevalence of CKD was high (17%-20%); hypertension prevalence was also high (22%-30%). AKI was not significantly associated with the development of CKD throughout follow-up. AKI was associated with hypertension development at 12 months after discharge (adjusted relative risk, 2.16; 95% confidence interval, 1.18 to 3.95), but not at subsequent visits. Children aged <2 years old at surgery had a significantly higher prevalence of hypertension during follow-up than older children (40% versus 21% at 3-month follow-up; 32% versus 13% at 48-month follow-up). CONCLUSIONS CKD and hypertension burden in the 4 years after pediatric cardiac surgery is high. Young age at surgery, but not AKI, is associated with their development.

Abstract
Background In sub-Saharan Africa, renal abnormalities are a major public health concern, especially in children living in Schistosoma haematobium endemic areas. However, there is a dearth of data on renal abnormalities among children living in Schistosoma mansoni endemic areas. The objective of the study was to assess the prevalence of renal abnormalities among school children in a Schistosoma mansoni endemic community in Northwestern Tanzania. Methods A cross-sectional study was conducted between January and March 2017 among school children aged 6–13 years, attending three primary schools located along the shoreline of Lake Victoria. A single urine sample was collected from each child and screened for S. mansoni using circulating cathodic antigen and for S. haematobium eggs using a urine filtration technique. A urine dipstick was used to screen for urine protein levels, creatinine levels, microalbuminuria, and red blood cells. Venous blood was obtained for estimation of creatinine level and for malaria diagnosis. The primary outcomes were the prevalence of renal abnormalities, defined by the presence of low estimated glomerular filtration rate (eGFR), proteinuria or microalbuminuria, and hematuria in urine. Results Of 507 children included in the final analysis, 49.9% (253/507) were male with a mean age of 8.51 ± 1.3 years. Overall, 64.0% (326/507) of the children were infected with S. mansoni, and 1.6% (8/507) of the children were infected with S. haematobium. A total of 71 (14%) of the children had proteinuria, 37 (7.3%) had hematuria, and 8 (1.6%) had a low estimated glomerular filtration rate (eGFR). Overall prevalence of renal abnormalities was 22.9%. Renal abnormalities (proteinuria) were associated with S. mansoni infection (OR = 4.9, 95% CI 2.1–11.2, p < 0.001) and having red blood cells in urine (OR = 5.3, 95% CI 2.5–11.2, p < 0.001). Conclusion Twenty-two percent of school children who participated in this study had renal abnormalities associated with S. mansoni infection. Given the high prevalence of S. mansoni, longitudinal epidemiological surveillance is warranted to measure the burden of renal abnormalities and assess the impact of the praziquantel treatment on these abnormalities.

Abstract
Background: Premature birth is associated with decreased nephron number and an increased risk for chronic kidney disease (CKD). To inform the development of guidelines for kidney follow up of children born prematurely, we undertook a study of individuals born extremely preterm, with the aim of characterizing the prevalence and predictors of microalbuminuria, elevated blood pressure, and/or abnormal kidney volume in adolescence. Methods: Study participants (n = 42) were born before 28 weeks of gestation and were enrolled at birth in the Extremely Low Gestational Age Newborns (ELGAN) study. When participants were 15 years old, we obtained 2 manual blood pressures, a spot urine microalbumin measurement, and sonographic measurements of kidney length and volume. Results: Of the 42 participants, 60% were male, 52% were Caucasian (18% Hispanic), and 43% were African-American. Their median age was 15 (IQR 15, 15.3) years. In 33.3% of the cohort, blood pressure was elevated (>120/80 mmHg). Microalbuminuria (>30 mg/g) was present in 11.9% of the cohort, and kidney volume below the 10th percentile of normative data was present in 14%. Twenty-one (50%) of the sample had at least one kidney abnormality (microalbuminuria, elevated blood pressures, and/or kidney hypoplasia); these individuals were more likely to have experienced neonatal hypotension [55% vs. 17% among those with no kidney abnormality, p = 0.02]. Conclusions: Half of adolescents in this subset of ELGAN cohort have at least one risk factor of kidney disease (reduced kidney volume, microalbuminuria, and/or elevated blood pressures) at 15 years of age. This study suggests the importance of monitoring kidney outcomes in children after extremely preterm birth, especially those with a history of neonatal hypotension.

Abstract
Childhood overweight and obesity affects more and more children. Whilst associations of childhood overweight with later outcomes such as hypertension, diabetes and cardiovascular disease have been well documented, less is known about the association of childhood overweight and obesity with kidney disease. We review the existing evidence for the association of childhood obesity with markers of childhood and adult kidney disease. Whilst there is some evidence for an association, studies have not been able to distinguish between childhood being a sensitive time to develop later kidney problems, or whether observed associations of childhood obesity with poor outcomes are driven by greater lifelong exposure to obesity.

Abstract
High blood pressure (BP) is becoming a growing health issue even in children and adolescents. Moreover, BP elevation in youth frequently translates into children and adult hypertension contributing to the development of cardiovascular disease. The detection of early markers of vascular damage, potentially leading to overt cardiovascular disease, is important for clinical decisions about if and how to treat hypertension and can be useful in monitoring the effectiveness of the treatment. The purpose of this review is to summarize the actual knowledge about subclinical organ damage (SOD) in hypertensive children and adolescents and its association with cardiovascular disease in children and young adults. Our focus is especially put on left ventricular mass, pulse wave velocity, carotid intima-media thickness and microalbuminuria. We also want to address the scientific evidence about possible regression of SOD and cardiovascular risk with the use of behavioural and specific anti-hypertensive therapy. Indications from current guidelines are critically discussed.

Abstract
Introdução: A obesidade é um dos fatores mais importantes para explicar o aumento incidência das Doenças Cardiovasculares (DCV). Dentre os múltiplos fatores de risco para estas doenças, a albuminúria é dos mais importantes. Objetivos: Avaliar os níveis de albuminúria e correlacionar com outros marcadores de risco cardiovascular em pacientes obesos que procuraram tratamento para obesidade. Materiais e métodos: Estudo transversal, retrospectivo, através dos prontuários de 183 pacientes de ambos os sexos, entre 18 e 65 anos, com índice de massa corpórea (IMC) ≥ 30 Kg/m². Todos os pacientes foram submetidos a exame físico e receberam um pedido de rotina laboratorial, incluindo de albuminúria em amostra isolada de urina. Resultados: Dados de albuminúria estavam disponíveis em 81 prontuários. Destes, 15 pacientes (18,5%) tinham valores acima de 17 mg/L de albuminúria. Nenhuma correlação foi encontrada entre os níveis de albuminúria e os parâmetros antropométricos (IMC, r=0,08; p=0,47; Cintura, r=0,17; p=0.11; Quadril, r=0,11; p=0,35; RCQ, r=0,03; p=0,75), Pressão Arterial (PA) sistólica (r=0,013; p=0,21) ou diastólica (r=0,11; p=0,32). Nenhuma diferença foi encontrada entre os pacientes que já usavam anti-hipertensivos ou não (p=0,25). Foi encontrada correlação entre os níveis de albuminúria e o high-density lipoprotein cholesterol (HDLc), (r=-0,27; p=0,012), além de uma tendência a significância com os níveis de Proteína C Reativa Ultrassensível (PCR-us; r=0,21; p= 0,081). Conclusão: Apesar da alta frequência (18,5%) de albuminúria em pacientes obesos, não foi encontrada correlação entre este marcador e os parâmetros antropométricos. Foi encontrado uma relação inversa da albuminúria com HDLc e uma tendência a significância com a PCR-us, sugerindo uma associação limitada entre a albuminúria e alguns marcadores específicos de risco cardiovascular.

Abstract
Proteinuria is an important biomarker commonly used to detect and manage kidney disease in children. There are now a variety of methods available to measure urinary protein loss, and physicians are faced with several contrasting strategies: 24-h or timed collection versus spot samples (first-morning or random), measurement of total urinary protein versus selective measurement of urinary albumin, unadjusted urine protein concentration versus protein-to-creatinine ratio and the use of dipstick versus laboratory-based methods. In this review, we will discuss the advantages and disadvantages of these different approaches. We will then summarise the evidence base for proteinuria as a clinical biomarker in different settings, including discussion of the current and potential role of measuring low-level albuminuria. Finally, we will highlight gaps in the literature and opportunities for further research into proteinuria among children.

Abstract
OBJECTIVE Obesity is clearly associated to kidney disease in adult population; however, there is scarce evidence in children and adolescents. The aim was to compare frequency of renal damage according to the presence of overweight-obesity in children and adolescents, as well as to compare nutritional and biochemical risk factors, according to the presence of kidney alterations. METHODS Cross-sectional study; 172 children and adolescents, 6-16 years old, without malnutrition, diabetes mellitus, hypertension and independent comorbid conditions associated to obesity or kidney disease, as well as transitory causes of microalbuminuria (MA) from a Primary Health-Care Unit were included. Clinical, biochemical, anthropometric and dietetic evaluations were measured in all subjects; subsequently they were classified as normal weight, overweight and obesity groups according to sex- and age-adjusted body mass index (BMI). Glomerular filtration rate (GFR, estimated by Schwartz equation) and albuminuria (albumin/creatinine ratio) were determined. Presence of kidney alterations was measured as decreased GFR (<90 mL/min/1.73m2), hyperfiltration (>170 mL/min/1.73m2) and MA (30-300 mg/g). RESULTS Compared with controls, subjects with overweight-obesity had significantly (P<.05) abdominal obesity (0 vs 69%), hypertension (19 vs 26%), hypertriglyceridemia (11 vs 47%), high low-density lipoprotein cholesterol (2 vs 8%) and low high-density lipoprotein cholesterol (HDL-cholesterol; 2 vs 28%), hyperuricemia (11 vs 28%) and hyperinsulinemia (8 vs 70%). Hyperfiltration and MA were present in 5 and 4 subjects with overweight/obesity, respectively, whereas decreased GFR was present in only 1 subject with obesity. Normal weight subjects had no kidney alterations. In multivariate analysis, kidney alterations were significantly predicted by higher BMI and lower HDL-cholesterol. CONCLUSIONS Kidney alterations were observed only in subjects with overweight (3.6%) and obesity (9.9%), who additionally, displayed cardiometabolic and kidney disease risk factors more frequently than normal weight subjects.

Diabetes Metab Syndr 2019; 13:830-843.

Abstract
BACKGROUND & AIM Previous studies have explored the relation of metabolic syndrome (MetS), its components and the risk of albuminuria/proteinuria but their results are inconsistent. Then, we aimed to conduct a meta-analysis in order to resolve these controversies. METHOD PubMed and Scopus were systematically searched from their inception to 1 march 2018. Risk estimates and their 95% confidence intervals were extracted and pooled using the random-effects approach. RESULT A total of 57 studies, 44 studies on albuminuria and 13 studies on proteinuria, with a total sample size of 10,603,067 participants, were included in this meta-analysis. Overall, MetS was contributed to higher risks of proteinuria (OR = 2.08, 95%CI = 1.85-2.34) and albuminuria (OR = 1.92, 95%CI = 1.71-2.15), independent of diabetes status; although, this relationship was more noticeable in studies that used the WHO definition of MetS and in non-East Asian populations. Also, the relationship between MetS and proteinuria was sex independent, while, for albuminuria was significant only in men. MetS components such as obesity, impaired fasting glucose, elevated blood pressure and hypertriglyceridemia were associated with significant increases in proteinuria and albuminuria risk, while lower HDL-Cholesterol was only linked to greater risk of proteinuria. Moreover, the total impact of MetS on proteinuria was more remarkable than each component of the syndrome and an escalating dose-response association was found between the number of MetS components and albuminuria risk. CONCLUSION MetS and its components are potential risk factors for albuminuria and proteinuria.

Abstract
Adolescents make up a quarter of the world's population and are important users of health services. In South Africa little is known about the extent of renal disease or outcomes in this group. Adolescents are a vulnerable age group, due to their neurocognitive development, engagement in high-risk social activities, prevalence of mental illness and increasing rates of HIV infection. In Africa access to renal replacement therapy is rationed, therefore the focus of renal disease must be one of prevention rather than dealing with the management of end stage renal disease. Treating adolescents is a challenging field, as compliance is essential as a preventative strategy. This review will outline how a cost effective adolescent service was established in a resource limited setting. The adolescent friendly clinic aims to ease transition of adolescents, improve engagement within the health service and ultimately aims to improve compliance. In order to treat adolescents, it is important to deliver age-appropriate treatment that can be implemented in any chronic disease setting to give the adolescent the greatest chance of success.

Abstract
Background Chronic kidney disease of unknown origin (CKDu) in Sri Lanka is grouped with several other epidemics of similar nature across the world as Chronic Interstitial Nephritis in Agricultural Communities (CINAC). In CKDu endemic countries, the focus has mainly been on adults. We hypothesized that studying distribution and factors associated with elevated urine albumin to creatinine ratio (UACR), an early marker of kidney injury, among children living in a CKDu endemic area may provide important clues about the onset and progression of the disease. Methods This cross sectional study was performed in rural primary schools in North Central Province of Sri Lnaka, a CKDu high endemic region. Total of 2880 students aging 5 to 11 years from 67 schools were enrolled for urinalysis in a random spot urine sample. Bedside Schwartz formula was used to measure estimated glomerular filtration rate (eGFR) on all children with UACR > 30 mg/g in Polonnaruwa district and a group of age matched controls. A standard multiple linear regression using log transformed UACR as the dependent variable was performed. Mean eGFR were compared between UACR elevated group and controls using independent sample t test. Results Median UACR was 10.3 mg/g. Sex, ethnicity, history of having a chronic disease and age uniquely contributed to the multiple regression model which only explained 2.8% of the variance in the log of the UACR (p < 0.001). Only 15 (0.5%) had UACR> 300 mg/g while 8.2% (n = 236) had UACR between 30 to 300 mg/g and 89.8% (n = 203) of them did not have a chronic disease (Chi square 2.21, p = 0.091). Mean eGFR was significantly lower in the group with elevated UACR (88.9 mg/dl/1.73 m2, 95% CI for mean 86.4- 91.3) compared to group with normal UACR (93.7 mg/dl/1.73 m2,95% CI 91.1- 96.3) (t 2.7, p 0.007). Three out of the four students with eGFR less than 60 mg/dl/1.73 m2 had moderately elevated UACR. Conclusion This study provides evidence to suggest that children in CKDu endemic regions are having an early renal damage. This observation needs to be investigated further in order to understand the worldwide epidemic of CKDu.

Abstract
BACKGROUND Childhood obesity represents a major health concern worldwide due to its well established detrimental effect on cardiovascular and its potential negative effect on kidney functions. However, biomarkers that can help diagnose early stages of kidney damage in obese children represent an unmet clinical need. OBJECTIVES In this study, we asked whether the prevalence of microalbuminuria, estimated glomerular filtration rate (eGFR) or hyperuricemia recorded in a wide cohort of obese children and adolescents would positively correlate with cardiometabolic dysfunction in these subjects. METHODS We carried out a cross-sectional study on 360 obese children and adolescents between the ages of 3-18 years, enrolled in a tertiary care center. Clinical and biochemical evaluations including oral glucose tolerance tests (OGTTs) were performed on all patients. Microalbuminuria was defined as urinary albumin-to-creatinine ratio (u-ACR) of 30-300 mg/g. All data are expressed as mean ± standard deviation (SD), absolute values or percentages. Sex age-specific and eGFR SDs were used for statistical analyses. Serum uric acid ≥ 5.5 mg/dL was considered abnormal. RESULTS The prevalence of microalbuminuria was 6.4%. Except for a lower insulinogenic-index, no correlations between microalbuminuria and cardiometabolic risk factors were detected. eGFR was < -1 SD and > 1 SD in 1.4% and 60.8% of subjects, respectively. Subjects with an eGFR > 1 SD had higher systolic blood pressure, liver enzymes, insulin resistance, glucose and insulin during OGTT, lower insulin sensitivity and a more prevalent microalbuminuria. Hyperuricemia (27.5%) increased the odds of hypertension, HDL ≤ 10th percentile and glucose ≥ 155.0 mg/dL after 60 minutes of OGTT. CONCLUSIONS A worse cardiometabolic profile was observed in subjects with an eGFR > 1 SD compared to other subgroups. Therefore, pediatric obese patients with eGFR > 1 SD or hyperuricemia should be closely monitored for microalbuminuria and post-challenge glucose and insulin secretion, all potential indicators of renal dysfunction in these young patients.

Abstract
With socioeconomic growth and cultural changes in China, the level of blood glucose may have changed in recent years. This study aims to detect the blood glucose distribution characteristics with a large size of health examination population.A total of 641,311 cases (360,259 males and 281,052 females) more than 18 years old during 2007 to 2015 were recruited from the Health Examination Center at West China hospital, Sichuan University.The percentage of cases with abnormal glucose level and the mean level of glucose were significantly increased since 2007 to 2015 overall. The percentage of cases with abnormal glucose level in males was significantly higher than that in females every year, and the percentage of cases with abnormal glucose level in aged population was higher than the young population. In addition, the mean level of glucose was higher in aged population with normal level of glucose than the young population with normal level of glucose, and the mean level of glucose was higher in males with normal level of glucose than the females with normal level of glucose.The population showed an increased level of blood glucose. Some preventive action may be adopted early and more attention can be paid to them.

Abstract
Microalbuminuria (MA) is a well-known predictor of cardiovascular disease and mortality in adults. However, these relationships remain unclear in adolescents. A few studies on association between MA and obesity have been conducted in adolescents. However, the association between MA and growth parameters such as height has not been studied, despite the fact that adolescence is a period of rapid physiological change. We, therefore, aimed to evaluate the association between MA and growth parameters, and the association between MA and obesity related cardiovascular risk factors after adjusting for growth. The study included 1,459 adolescents (847 boys and 612 girls) aged 12-18 years who participated in the Korean National Health and Nutrition Examination Survey (2011-2013). A urine albumin/creatinine ratio (UACR) of 30-299 mg/g in a morning urine sample was considered to reflect MA. MA was detected in 53 (3.6%) including 24 girls. Height z-score of adolescents with MA was greater than that of normoalbuminuric adolescents (0.87 vs. 0.38; P < 0.01). Upon multiple regression analysis, UACR was associated with lower weight z-score (β = -0.100, P < 0.01) and higher height z-score (β = 0.069, P < 0.01). In term of cardiovascular risk factors, the UACR was not associated with fasting glucose, high-density-lipoprotein cholesterol, or triglyceride levels. Adolescents with MA tend to be thin and tall. MA is not a useful screening method for obesity-related cardiovascular risk in adolescents, but instead MA is associated with taller height and lower weight, growth-related parameters in adolescence.
