Higher Prevalence Of Albuminuria Research Articles

Prevalence of Diabetic Nephropathy among Patients of Type 2 Diabetes at Tertiary Care Hospital Lahore

Background: Diabetic nephropathy is a significant complication of Type 2 Diabetes Mellitus, often leading to chronic kidney disease (CKD) and potentially progressing to End-Stage Renal Disease (ESRD). Approximately 90% of individuals with diabetes and hypertension may develop ESRD in the later stages of the disease. Objective: The study aimed to determine the prevalence of diabetic nephropathy among patients with type 2 diabetes at a tertiary care hospital in Lahore. Methods: This retrospective study included 100 reports from the chemical pathology and microbiology laboratory at Fatima Memorial Hospital, Lahore, covering renal function tests (RFT) such as Urea, Blood Urea Nitrogen (BUN), Creatinine, and estimated Glomerular Filtration Rate (eGFR), as well as HbA1c levels and Albuminuria. Data collection involved accessing electronic medical records (EMRs) to obtain comprehensive clinical data, including patients' medical history, duration of diabetes, glycemic control measurements, blood pressure, and prescribed medications. The study included patients with type 2 diabetes and kidney disease, excluding those without renal disease. Ethical approval was obtained from the Institutional Review Board (IRB) of FMH College of Medicine and Dentistry, adhering to the principles of the Declaration of Helsinki. Data were analyzed using IBM SPSS version 25, with categorical variables expressed as frequencies and percentages and continuous variables as mean ± standard deviation (SD). Correlation analysis was conducted, with a p-value of less than 0.05 indicating statistical significance. Results: The study included 100 participants, with 53% being male and 47% female. The mean age was 59.19 years (SD = 18.812), ranging from 18 to 91 years. Albuminuria was present in 88% of participants. Elevated serum creatinine was observed in 93%, HbA1c levels >6.4% in 68%, high urea levels in 87%, and eGFR <60 in 14%. Correlation analysis showed a significant positive correlation between HbA1c and eGFR (Spearman's rho = 0.432, p < 0.001) and between urea and serum creatinine (Spearman's rho = 0.701, p < 0.001). Conclusion: The high prevalence of albuminuria and elevated renal function markers among individuals with type 2 diabetes underscores the importance of early detection and comprehensive management. Regular screening for urinary albumin, stringent glycemic control, and optimal blood pressure management are crucial for preventing the progression of diabetic nephropathy.

Association between triglyceride-glucose index and chronic kidney disease: results from NHANES 1999–2020

Abstract Aims Examining the connection between the triglyceride-glucose (TyG) index and chronic kidney disease (CKD) was the aim of this investigation. Methods Data from the National Health and Nutrition Examination Survey (NHANES) covering the years 1999–2020 were analyzed in this study. The TyG index was calculated as Ln (triglycerides (mg/dl) * fasting glucose (mg/dl)/2). The two criteria used to diagnose CKD were low estimated glomerular filtration rate (eGFR) (eGFR < 60 mL/min/1.73m2) or albuminuria (urine albumin-to-creatinine ratio (ACR) ≥ 30 mg/g). To look into the independent associations between TyG index levels with CKD, albuminuria, and low-eGFR, weighted multivariable logistic regression and generalized additive models were employed. To assess and contrast the diagnostic ability, receiver operating characteristic (ROC) curves were employed. Results Out of 18,078 total participants recruited, 48.54% were male. 8.48 + 0.68 was the mean value of the TyG index. CKD, albuminuria, and low-eGFR were common, with respective prevalences of 17.06%, 11.26%, and 8.03%, respectively. The TyG index and CKD were observed to positively correlate (OR = 4.03; 95% CI 1.81, 8.96). In US adults between the ages of 41 and 60, a J-shaped connection was found between the two. Furthermore, a higher TyG index is associated with a higher prevalence of albuminuria (OR = 6.11; 95% CI 2.64, 14.14). Subgroup analyses and interaction tests revealed that different stratifications did not significantly affect the relationship between TyG index and CKD, albuminuria, and low-eGFR. Comparing the TyG index to other indicators [lipid accumulation product (LAP), Visceral adiposity index (VAI), and the triglyceride glucose–body mass index (TyG-BMI)], it may be more accurate and discriminative in predicting CKD and albuminuria. Conclusion When predicting CKD and albuminuria, the TyG index may be a more useful marker when compared to other markers (LAP, VAI, and TyG-BMI index). In addition, in American adults aged 41–60, the TyG index shows a J-shaped relationship with CKD. As a result, when assessing the kidney health of US adults, we must pay close attention to the significance of the TyG index.

Differences in the epidemiology, management and outcomes of kidney disease in men and women.

Improved understanding of differences in kidney disease epidemiology, management and outcomes in men and women could help nephrologists to better meet the needs of their patients from a sex- and gender-specific perspective. Evidence of sex differences in the risk and outcomes of acute kidney injury is mixed and dependent on aetiology. Women have a higher prevalence of chronic kidney disease (CKD) stages 3-5 than men, whereas men have a higher prevalence of albuminuria and hence CKD stages 1-2. Men show a faster decline in kidney function, progress more frequently to kidney failure and have higher mortality and risk of cardiovascular disease than women. However, the protective effect of female sex is reduced with CKD progression. Women are less likely than men to be aware of, screened for and diagnosed with CKD, started on antiproteinuric medication and referred to nephrologist care. They also consistently report a poorer health-related quality of life and a higher symptom burden than men. Women experience greater barriers than men to access the waiting list for kidney transplantation, particularly with respect to older age and obesity. However, women also have longer survival than men after transplantation, which may partly explain the comparable prevalence of transplantation between the sexes.

Diabetic Retinopathy and Chronic Kidney Disease: Associations and Comorbidities in a Large Diabetic Population - The Tongren Health Care Study.

The aim of the study was to investigate associations between diabetic retinopathy (DR) and chronic kidney disease (CKD) in patients with type 2 diabetes (TD2). The participants of the cross-sectional, community-based Tongren Health Care Study underwent a detailed medical and ophthalmological examination. We defined TD2 by a fasting plasma glucose concentration of ≥7.0 mmol/L or a medical history. CKD was classified as either reduced estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 mm2 or presence of albuminuria. DR was assessed using color fundus photographs. Out of 62,217 participants of the Tongren Health Care Study, 5,103 (8.2%) patients had TD2. The prevalence of DR was 12.8% (95% CI, 11.8%, 13.7%), CKD was 13.3% (95% CI, 12.4%, 14.3%), and the subtypes of CKD including reduced eGFR and albuminuria was 4.6% (95% CI, 4.2%, 5.1%) and 10.1% (95% CI, 9.3%, 10.9%), respectively. DR was detectable in 21.0% of the patients with CKD, while CKD was present in 20.9% of the DR patients. Higher DR prevalence was associated with higher prevalence of albuminuria and reduced eGFR (both p < 0.05). Factors independently associated with the presence of CKD instead of DR were older age (p < 0.001, OR = 1.05), a higher body mass index (p < 0.001, OR = 1.14), a higher serum concentration of triglycerides (p < 0.001, OR = 1.26), and a lower blood glucose (p < 0.001, OR = 0.93). Having hypertension was additionally associated with the presence of reduced eGFR as compared with DR (p = 0.005, OR = 4.47). TD2 patients of older age and with higher body mass index, hypertension, and dyslipidemia had a higher probability of being affected by CKD rather than DR, while those with a higher blood glucose level were more prone to DR than CKD.

Endotoxemia Correlates with Kidney Function and Length of Stay in Critically Ill Patients

Introduction: Endotoxin is a key driver of sepsis, which frequently causes acute kidney injury (AKI). However, endotoxins may also be found in non-bacteremic critically ill patients, likely from intestinal translocation. Preclinical models show that endotoxins can directly injure the kidneys, and in COVID-19 patients, endotoxemia correlated with AKI. We sought to determine correlations between endotoxemia and kidney and hospital outcomes in a broad group of critically ill patients. Methods: In this single-center, serial prospective study, 124 predominantly Caucasian adult patients were recruited within 48 h of admission to Stony Brook University Hospital Intensive Care Unit (ICU). Demographics, vital signs, laboratory data, and outcomes were collected. Circulating endotoxin was measured on days 1, 4, and 8 using the endotoxin activity assay (EAA). The association of EAA with outcomes was examined with EAA: (1) categorized as <0.6, ≥0.6, and nonresponders (NRs); and (2) used as a continuous variable. Results: Patients with EAA ≥0.6 had a higher prevalence of proteinuria, and lower arterial oxygen saturation (SaO₂) to fraction of inspired oxygen (FiO₂) (SaO₂/FiO₂) ratio versus patients with EAA <0.6. EAA levels positively correlated with serum creatinine (sCr) levels on day 1. Patients whose EAA level stayed ≥0.6 had a slower decline in sCr compared to those whose EAA started at ≥0.6 and subsequently declined. Patients with AKI stage 1 and EAA ≥0.6 on day 1 showed slower decline in sCr compared to patients with stage 1 AKI and EAA <0.6. EAA ≥0.6 and NR patients had longer hospital stay and delayed ICU discharge versus EAA <0.6. Conclusions: High EAA levels correlated with worse kidney function and outcomes. Patients whose EAA levels fell, and those with AKI stage I and day 1 EAA <0.6 recovered more quickly compared to those with EAA ≥0.6, suggesting that removal of circulating endotoxins may be beneficial in critically ill patients.

Association between weight-adjusted-waist index and chronic kidney disease: a cross-sectional study

AimsWe aimed to investigate the potential association between weight-adjusted-waist index (WWI) and chronic kidney disease (CKD).Design and methodsThis research examined data collected from the National Health and Nutrition Examination Survey (NHANES) spanning from 1999 to 2020. CKD was defined as the low estimated glomerular filtration rate (eGFR) or the existence of albuminuria (urinary albumin-to-creatinine ratio (ACR) ≥ 30mg/g). Low-eGFR was described as eGFR < 60 mL/min/1.73m2. The associations between WWI with CKD, albuminuria, and low-eGFR were examined using generalized additive models and weighted multivariable logistic regression models. We also analyzed the associations of other obesity indicators with CKD, albuminuria, and low-eGFR, including body mass index (BMI), waist-to-height ratio (WHtR), waist circumference(WC), height, and weight. The receiver operating characteristic (ROC) curves were used to assess and compare their diagnostic abilities.ResultsMales made up 48.26% of the total 40,421 individuals that were recruited. The prevalences of CKD, albuminuria, and low-eGFR were 16.71%, 10.97%, and 7.63%, respectively. WWI was found to be positively linked with CKD (OR = 1.42; 95% CI: 1.26, 1.60). A nonlinear connection between WWI and CKD was found using smooth curve fitting. Additionally, a higher prevalence of albuminuria is linked to a higher level of WWI (OR = 1.60; 95% CI: 1.40, 1.82). Different stratifications did not substantially influence the connection between WWI and CKD, albuminuria, and low-eGFR, according to subgroup analysis and interaction tests. We observed higher height was related to higher low-eGFR prevalence (OR = 1.05; 95% CI: 1.03, 1.06). ROC analysis revealed that WWI had the best discrimination and accuracy for predicting CKD and albuminuria compared to other obesity indicators (BMI, WHTR, WC, height and weight). In addition, height had the highest area under the curve (AUC) value for predicting low-eGFR.ConclusionWWI is the best obesity indicator to predict CKD and albuminuria compared to other obesity indicators (BMI, WHTR, WC, height, and weight). WWI and CKD and albuminuria were found to be positively correlated. Furthermore, height had the strongest ability to predict low-eGFR. Therefore, the importance of WWI and height in assessing kidney health in US adults should be emphasized.

1355-P: Risk of Chronic Kidney Disease in Early-Onset Type 2 Diabetes in Mexico

Patients with early onset type 2 diabetes (EOD) seem to be at increased risk of developing complications. Screening and diagnosis for CKD is poorly executed in primary care (PC) of low-and-middle income countries. Thus, we aimed to analyze the presence of CKD in EOD in comparison with later-onset diabetes (LOD). Data were obtained from the largest cohort of patients with T2D evaluated for CKD within the PC in Mexico (DIABEMPIC). EOD and LOD were defined as the age of diagnosis &amp;lt;40 and ≥40 years, respectively. CKD assessment included albuminuria through urinary albumin-creatinine ratio (≥30mg/g for CKD) and estimated glomerular filtration rate (eGFR≤60 ml/min/1.73m2 for CKD). A total of 1,592 patients were included. The burden of CKD at different diabetes durations are shown in Table 1. The prevalence of overall CKD was significantly higher in the EOD group (p&amp;lt;0.008), associated to a greater presence of albuminuria; a higher prevalence of albuminuria was observed after 10 years of diagnosis in the EOD (p&amp;lt;0.0001). In the univariate analysis, EOD was associated with an increased risk of CKD (OR 1.33, 95%CI 1.08-1.65). In conclusion, EOD patients presented a higher risk of CKD, particularly on account for albuminuric-CKD phenotype, even though they are comparatively younger. Our results enhance the need for the management of risk factors and proper screening of CKD in T2D, especially in EOD, in PC settings, and through albuminuria measurement.

SARS-CoV-2 spike protein inhibits megalin-mediated albumin endocytosis in proximal tubule epithelial cells

Patients with COVID-19 have high prevalence of albuminuria which is used as a marker of progression of renal disease and is associated with severe COVID-19. We hypothesized that SARS-CoV-2 spike protein (S protein) could modulate albumin handling in proximal tubule epithelial cells (PTECs) and, consequently contribute to the albuminuria observed in patients with COVID-19. In this context, the possible effect of S protein on albumin endocytosis in PTECs was investigated. Two PTEC lines were used: HEK-293A and LLC-PK1. Incubation of both cell types with S protein for 16 h inhibited albumin uptake at the same magnitude. This effect was associated with canonical megalin-mediated albumin endocytosis because: (1) DQ-albumin uptake, a marker of the lysosomal degradation pathway, was reduced at a similar level compared with fluorescein isothiocyanate (FITC)-albumin uptake; (2) dextran-FITC uptake, a marker of fluid-phase endocytosis, was not changed; (3) cell viability and proliferation were not changed. The inhibitory effect of S protein on albumin uptake was only observed when it was added at the luminal membrane, and it did not involve the ACE2/Ang II/AT1R axis. Although both cells uptake S protein, it does not seem to be required for modulation of albumin endocytosis. The mechanism underlying the inhibition of albumin uptake by S protein encompasses a decrease in megalin expression without changes in megalin trafficking and stability. These results reveal a possible mechanism to explain the albuminuria observed in patients with COVID-19.

Albuminuria Testing in Hypertension and Diabetes: An Individual-Participant Data Meta-Analysis in a Global Consortium

Albuminuria is an under-recognized component of chronic kidney disease definition, staging, and prognosis. Guidelines, particularly for hypertension, conflict on recommendations for urine albumin-to-creatinine ratio (ACR) measurement. Separately among 1 344 594 adults with diabetes and 2 334 461 nondiabetic adults with hypertension from the chronic kidney disease Prognosis Consortium, we assessed ACR testing, estimated the prevalence and incidence of ACR ≥30 mg/g and developed risk models for ACR ≥30 mg/g. The ACR screening rate (cohort range) was 35.1% (12.3%–74.5%) in diabetes and 4.1% (1.3%–20.7%) in hypertension. Screening was largely unrelated to the predicted risk of prevalent albuminuria. The median prevalence of ACR ≥30 mg/g across cohorts was 32.1% in diabetes and 21.8% in hypertension. Higher systolic blood pressure was associated with a higher prevalence of albuminuria (odds ratio [95% CI] per 20 mm Hg in diabetes, 1.50 [1.42–1.60]; in hypertension, 1.36 [1.28–1.45]). The ratio of undetected (due to lack of screening) to detected ACR ≥30 mg/g was estimated at 1.8 in diabetes and 19.5 in hypertension. Among those with ACR &lt;30 mg/g, the median 5-year incidence of ACR ≥30 mg/g across cohorts was 23.9% in diabetes and 21.7% in hypertension. Incident albuminuria was associated with initiation of renin-angiotensin-aldosterone system inhibitors (incidence-rate ratio [95% CI], diabetes 3.09 [2.71–3.53]; hypertension 2.87 [2.29–3.59]). In conclusion, despite similar risk of albuminuria to those with diabetes, ACR screening in patients with hypertension was low. Our findings suggest that regular albuminuria screening should be emphasized to enable early detection of chronic kidney disease and initiation of treatment with cardiovascular and renal benefits.

1260-PUB: Type 2 Diabetes and Congestive Heart Failure Are Mutually Independent Predictors of the Presence of Albuminuria

Albuminuria is a well-known characteristic of diabetic nephropathy and it is also present in a large portion of patients with congestive heart failure (CHF). However, the single and joint effects of type 2 diabetes mellitus (T2DM) and CHF on albuminuria are unknown. This issue therefore was addressed in the present study. We investigated 180 patients with CHF, of whom 83 had T2DM (CHF+/T2DM+) and 97 did not have diabetes (CHF+/T2DM-) and 223 controls without CHF, of whom 39 had T2DM (CHF-/T2DM+) and 184 did not have diabetes (CHF-/T2DM-). The prevalence of albuminuria was lowest in CHF-/T2DM- subjects (8.7%). When compared to this group it was significantly higher in CHF-/T2DM+ (23.1%, p=0.010), CHF+/T2DM- (38.1%, p&amp;lt;0.001) and CHF+/T2DM+ patients (62.7%, p&amp;lt;0.001). It was highest in CHF+/T2DM+ patients, in whom it was higher than in CHF-/T2DM+ (p&amp;lt;0.001) and in CHF+/T2DM- (p=0.001) patients; a trend towards a higher prevalence of albuminuria in CHF-/T2DM+ patients vs. CHF+/T2DM- patients did not reach statistical significance (p=0.093). In logistic regression analysis, CHF and T2DM were mutually independent predictors of albuminuria, when adjusted for age, sex, body mass index, LDL cholesterol, history of smoking and hypertension, as well as for the use of statins and ACE inhibitors/angiotensin II receptor blockers (OR 2.57 [95% CI 1.47-4.51]; p=0.001 and OR 4.15 [2.18 - 7.88]; p&amp;lt;0.001, respectively). We conclude that T2DM and CHF are mutually independent predictors of albuminuria. Disclosure M. Maechler: None. C. H. Saely: None. A. Vonbank: None. B. Larcher: None. A. Mader: None. L.

Albuminuria Is Associated with Steatosis Burden in Patients with Type 2 Diabetes Mellitus and Nonalcoholic Fatty Liver Disease.

BackgroundThis study aimed to investigate the association between hepatic steatosis burden and albuminuria in Korean patients with type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD).MethodsWe recruited 100 patients with both T2DM and NAFLD, but without chronic kidney disease. Albuminuria was defined as a spot urinary albumin-to-creatinine ratio (ACR) ≥30 mg/g. Transient elastography was performed, and the steatosis burden was quantified by controlled attenuation parameter (CAP) with significant steatosis defined as CAP >302 dB/m.ResultsThe prevalence of significant steatosis and albuminuria was 56.0% and 21.0%, respectively. Subjects with significant steatosis were significantly younger and had a significantly shorter duration of T2DM, greater waist circumference, and higher body mass index, total cholesterol, triglyceride, and low density lipoprotein cholesterol levels, than subjects without severe NAFLD (all P<0.05). Albuminuria was higher in patients with significant steatosis than in patients without significant steatosis (32.1% vs. 6.8%, P=0.002). Urinary ACR showed a correlation with CAP (r=0.331, P=0.001), and multiple linear regression analysis revealed a significant association between a high degree of albuminuria and high CAP value (r=0.321, P=0.001). Additionally, multivariate logistic regression analysis demonstrated the independent association between urinary ACR and significant steatosis after adjustment for confounding factors including age, body mass index, duration of T2DM, low density lipoprotein level, and renin-angiotensin system blocker use (odds ratio, 1.88; 95% confidence interval, 1.31 to 2.71; P=0.001).ConclusionT2DM patients with NAFLD had a higher prevalence of albuminuria, which correlated with their steatosis burden.

Body Mass Index and Urinalysis Markers in the Seemingly Healthy Young Adults

Higher prevalence of albuminuria, glycosuria, and haematuria was reported in the obese people than control. We aimed to analyze the BMI and urinalysis markers among the university students aged 18-21 years old in the IIKBW, Kediri to study any correlations and differences between these variables, which to the best of our knowledge has yet widely reported in Indonesia. This study has ethics approval from Universitas Airlangga, Surabaya. The BMI was analyzed from the body weight and height of male (n=74) and female (n=76) students with no health problems recorded. The pH, nitrites, protein, erythrocytes, glucose in the urine were measured qualitatively with a dip-stick method, blinded, using the midstream urine sample collected in the morning. Data were analyzed using SPSS 17, with a level of significance of p&lt;0.05. Abnormal pH (n=75), positive nitrites (n=24), haematuria (n=6), and proteinuria (n=149) were recorded. About 22% of students suffered from type I obesity, and 8.7% of type II. Males were significantly suffered from the obesity whilst females from the overweight (p&lt;0.05). No significant correlations between the BMI and each urinalysis marker (BMI and nitrites p=0.936; BMI and protein p=1; BMI and pH p=0.835; BMI and blood, p=0.486; respectively); no one were found with glycosuria. No significant differences either on the BMI or the 5 urinalysis markers between male and female groups (p&gt;0.05). Whilst no positive glycosuria samples were identified; 18.9% of males and 13.2% of females have positive nitrites, 100% of males and 98.7% of females have positive proteinuria, 2.7% of males and 7.9% of females have positive haematuria. There were 7.33% of males and 6% of females having an increased pH; whilst 20.66% of males and 16% of females having a decreased pH. Amongst the seemingly healthy university students, we found cases of urinalysis marker impairment, although no significant correlations on the BMI to the urinalysis markers that may be representing early detection for renal diseases were observed.

P0225THE PRESENCE OF SIMPLE RENAL CYST IS ASSOCIATED WITH INCREASED RISK OF ALBUMINURIA IN YOUNG ADULTS

Abstract Background and Aims It is well-known that the prevalence of simple renal cyst increases with age. However, simple cysts are occasionally found in adults younger than 40 years of age. This cross-sectional study evaluated the clinical significance of simple renal cysts in young adults, focusing on the associations with hematuria and albuminuria. Method Adults younger than 40 years who received a comprehensive medical checkup from January 2005 to December 2013 were included. Simple renal cysts were identified by ultrasonography. Results Among 5832 subjects, renal cysts were found in 276 (4.7%). Subjects diagnosed with polycystic kidney disease (n=5) or medullary sponge kidney (n=1) were excluded from the analyses. A single cyst and multiple cysts were found in 234 (4.0%) and 42 (0.7%) subjects, respectively. The locations of single cyst were cortex in 187, medulla in 26, and parapelvic region in 21. Age (odds ratio [OR], 1.07; 95% confidence interval [CI], 1.02-1.12 per 1-year increment, P = 0.002), systolic BP (OR, 1.01; 95% CI, 1.00-1.02 per 1-mmHg increment, P = 0.006), and hypertension (OR, 1.85; 95% CI, 1.24-2.76, P = 0.003) were independent predictors of the presence of simple cyst. The presence of cysts was not associated with increased prevalence of hematuria. While, the subjects with cysts had higher prevalence of albuminuria than those without cysts (11.3% vs. 4.5%, P &amp;lt;0.001). Multivariate analyses of albuminuria revealed that the presence of simple renal cyst was associated with a 2.30-fold increase in the prevalence of albuminuria (95% CI 1.512-3.519, P &amp;lt;0.001) independently of other risk factors. The location of the cysts was not related to the prevalence of albuminuria. Conclusion The presence of simple renal cysts was independently associated with increased prevalence of albuminuria. The causal relationship between renal cysts and albuminuria needs to be elucidated in further studies.

Risk Factors and Management of Kidney Diseases in Saudi Women with Diabetes

Background:The prevalence of diabetic kidney diseases (DKD) in the Saudi population is increasing and its prevalence has been reported as 37.4%. Recently, a higher prevalence of albuminuria in women has been proven through population-based studies.Objectives:Recently, the Kingdom of Saudi Arabia (KSA) has witnessed many changes in women’s activities, and women are more actively participating in the social and cultural development of the country. Thus, focusing on women’s health-related issues has become crucial. The necessity of research focusing on the influence of various risk factors on DKD has emerged as a priority.Methods:The literature search was done by search engines and databases (PubMed, Google scholar and EMBASE). From a total of 21 selected articles, 18 articles are included in this study.Results:This review emphasizes on the higher influence of certain DKD risk factors on Saudi women including a high prevalence of glucose intolerance during pregnancy, obesity due to lack of physical activity, and genetic predisposition due to consanguineous marriages, etc.Conclusion:This study can raise awareness regarding the prevention and management of DKD in Saudi diabetic women.

High prevalence of albuminuria amongst people who inject drugs: A cross-sectional study

Albuminuria is a key biomarker for cardiovascular disease and chronic kidney disease. Our study aimed to describe the prevalence of albuminuria amongst people who inject drugs in London and to test any potential associations with demographic characteristics, past diagnoses, and drug preparation and administration practices. We carried out a cross-sectional survey amongst people who use drugs in London. The main outcome measure was any albuminuria including both microalbuminuria and macroalbuminuria. Three-hundred and sixteen samples were tested by local laboratory services. Our study initially employed point-of-care testing methods but this resulted in a high number of false positives. Our findings suggest the prevalence of albuminuria amongst PWID is twice that of the general population at 19% (95%CI 15.3–24.0%). Risk factors associated with albuminuria were HIV (aOR 4.11 [95% CI 1.37–12.38]); followed by overuse of acidifier for dissolving brown heroin prior to injection (aOR 2.10 [95% CI 1.04–4.22]). Albuminuria is high amongst people who inject drugs compared to the general population suggesting the presence of increased cardiovascular and renal pathologies. This is the first study to demonstrate an association with acidifier overuse. Dehydration may be common amongst this population and may affect the diagnostic accuracy of point-of-care testing for albuminuria.

Parity is associated with albuminuria and chronic kidney disease: a population-based study.

Background and aims: Epidemiological studies have shown that increasing parity is associated with risk of hypertension and diabetes in parous women. However, the relationship between the parity degree with chronic kidney disease (CKD) is still unknown.Results: Parous women with higher parity had increased age, body mass index, waist circumference, systolic blood pressure, fasting plasma glucose, fasting insulin and decreased high-density lipoprotein cholesterol, eGFR and education levels. Compared with women with one-child birth, those with more than two-child births had greater prevalence of increased urinary albumin excretion (odds ratios [ORs] 1.53, 95% confidence intervals [CI], 1.03 - 2.28) and CKD (ORs 1.79, 95% CI, 1.24 - 2.58) after multiple adjustments. In dose-response analysis, a nonlinear relationship of parity degree with albuminuria and CKD was detected.Conclusion: Parity is associated with higher prevalence of albuminuria and CKD in middle-aged and elderly Chinese women.Methods: We conducted a community-based study in 6,946 women to investigate the association of parity with albuminuria and CKD. Increased urinary albumin excretion was defined as albumin-to-creatinine ratio (ACR) greater or equal than 30 mg/g. CKD was defined as estimated glomerular filtration rate (eGFR) less than 60 mL/min per 1.73 m² or presence of albuminuria.

APOL1 Nephropathy Risk Alleles and Mortality in African American Adults: A Cohort Study

APOL1 nephropathy risk alleles are associated with the development of chronic kidney disease (CKD) in African Americans. Although CKD is an established risk factor for mortality, associations of APOL1 risk alleles with mortality are uncertain. Prospective cohort. 10,380 African American and 17,485 white American participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study. APOL1 nephropathy risk alleles. All-cause and cause-specific mortality. Cox proportional hazards models were used to examine the association of APOL1 high-risk genotypes (2 risk alleles) versus APOL1 low-risk genotypes (0/1 risk allele) with all-cause and cause-specific mortality in African Americans and examine the risk for all-cause mortality in African Americans with high-risk genotypes versus African Americans with low-risk genotypes and white Americans. APOL1 high-risk participants were younger and had a higher prevalence of albuminuria than low-risk participants. There was no statistically significant association ofAPOL1 high- versus low-risk genotypes withall-cause mortality in models adjusted forsociodemographic variables, comorbid conditions, and kidney function (HR, 0.88; 95% CI, 0.77-1.01). After further adjustment for genetic ancestry in a subset with available data, a statistically significant association emerged (HR, 0.81; 95% CI, 0.69-0.96). Associations differed by CKD status (Pinteraction=0.04), with African Americans with high-risk genotypes having lower risk for mortality than those with low-risk genotypes in fully adjusted models (HR, 0.78; 95% CI, 0.62-0.99) among those with CKD, but not those without CKD (HR, 0.84; 95% CI, 0.66-1.05). Compared with white Americans, African Americans with high-risk genotypes had a similar rate of mortality, whereas African Americans with low-risk genotypes had a higher rate of mortality (HR, 1.07; 95% CI, 1.00-1.14) in fully adjusted models. Lack of follow-up measures of kidney function. African Americans with high-risk APOL1 genotypes had lower mortality than those with low-risk genotypes in multivariable-adjusted models including genetic ancestry.

522-P: Long-Term Renal Outcomes in Young Onset Type 2 Diabetes

Young adult onset type 2 diabetes (YT2DM) is an aggressive disease. Cross-sectional studies have shown a higher prevalence of albuminuria in YT2DM compared to age-matched young adults with T1DM (YT1DM). Whether this translates to poorer long-term renal outcomes has not been widely studied. We aimed (i) to examine progression to renal replacement therapy (RRT) and renal-related death (RRD) in our young adult population, and (ii) to examine survival on RRT for those individuals who reached end stage renal disease. We performed probabilistic linkage of prospectively collected data from the RPA Diabetes Centre eMR to the Australian National Death Index and the Australian and New Zealand Dialysis and Transplant Registry up to 31/12/2015. In our patient cohort diagnosed between the ages of 15 and 35 years, 1,248 had YT1DM and 1,534 had YT2DM. After a median (IQR) observation of 13.6 (6.9-20.7) years, 56 (4.5%) of YT1DM vs. 98 (6.4%) of YT2DM reached the combined renal end-point of RRT/RRD. Analysis of Kaplan-Meier survival curves demonstrated a greater rate of progression of renal disease in YT2DM (Log-rank p=0.003). Cox proportional hazard modelling of RRT/RRD with adjustment for gender, ethnicity and duration of diabetes exposure was undertaken. The HR (95% CI) for an adverse renal outcome in YT2DM relative to YT1DM was 2.0 (1.4-2.9), p&amp;lt;0.001. This HR was attenuated when further adjustments were made for HbA1c, blood pressure, BMI and cholesterol. Similar results were obtained after multiple imputation for missing data. For the 80 young adults who commenced RRT, there were 19 deaths (70%) in the YT1DM subgroup and 26 deaths (49%) in the YT2DM subgroup after a median (IQR) observation time of 4.2 (2.2-9.1) years. KM survival analysis demonstrated equally poor survival in YT1DM and YT2DM. Cox regression with transplant as a time-varying covariate also showed non-significance. These data highlight the more rapidly progressive renal disease seen in YT2DM compared to YT1DM; however, survival on RRT appears to be equally poor for both diabetes types. Disclosure T.

Effects of Metreleptin on Proteinuria in Patients With Lipodystrophy.

Patients with lipodystrophy have high prevalence of proteinuria. To assess kidney disease in patients with generalized (GLD) vs partial lipodystrophy (PLD), and the effects of metreleptin on proteinuria in patients with lipodystrophy. Prospective, open-label studies of metreleptin treatment in patients with GLD and PLD at the National Institutes of Health. The 24-hour urinary albumin and protein excretion rates, estimated glomerular filtration rate (eGFR), and creatinine clearance (CrCl) were measured at baseline and during up to 24 months of metreleptin treatment. Patients with increases in medications affecting outcome measures were excluded. At baseline, patients with GLD had significantly greater albuminuria, proteinuria, eGFR, and CrCl compared with patients with PLD. CrCl was above the normal range in 69% of patients with GLD and 39% with PLD (P = 0.02). With up to 24 months of metreleptin treatment, there were significant reductions in albuminuria and proteinuria in patients with GLD, but not in those with PLD. No changes in eGFR or CrCl were observed in patients with GLD or PLD during metreleptin treatment. Patients with GLD had significantly greater proteinuria than those with PLD, which improved with metreleptin treatment. The mechanisms leading to proteinuria in lipodystrophy and improvements in proteinuria with metreleptin are not clear. Hyperfiltration was also more common in GLD vs PLD but did not change with metreleptin.
