The association of RBP4 with chronic kidney diseases in southern Chinese population

BackgroundRetinol binding protein 4 (RBP4), as a novel adipokine, has been proven to be highly related to insulin resistance, obesity, diabetes, hypertension, hyperuricemia and other metabolic diseases, which are all risk factors for chronic kidney disease (CKD). However, there is a lack of sufficient studies to explore the relationship between RBP4 and CKD, and no reports have described the predictive value of RBP4 for CKD. This study was designed to clarify the relationship between RBP4 and CKD and its potential predictive value.MethodsOur team has conducted a large-scale cross-sectional survey that contained 2117 individuals on the southern coast of China. Correlation test, logistic regression analysis were used to evaluate the association between RBP4 and CKD. Receiver operating characteristic (ROC) were used to evaluate the optimal cut-off and predictive value of RBP4 for predicting CKD.ResultsBy using the quartile grouping method, the population was divided into four groups according to the RBP4 level. As the RBP4 level increased, the prevalence of CKD also gradually increased among different groups. RBP4 was also correlated with various metabolic risk factors, such as blood glucose, blood lipids, blood pressure, waist circumference, uric acid, and with kidney function indicators such as creatinine, urine protein. Logistic regression analysis found that after adjusting for confounders, RBP4 remained significantly associated with CKD, independent of metabolic risk factors. ROC analysis showed that RBP4 as a single index, AUC (0.666) was superior to Scr, FBG, Log HOMA-IR, WC, TG, VLDL-C, UA, HDL-C, LDL-C, and that combining RBP4 indicator and other common risk factors of CKD can improve the accuracy for predicting CKD.ConclusionThis study found that the RBP4 was strongly correlated with CKD, RBP4 may become a valuable marker and have strong power for predicting CKD.

Coexisting Tubulointerstitial Inflammation and Damage Is a Risk Factor for Chronic Kidney Disease in Patients With Lupus Nephritis.

This study aims to determine whether the concurrent presence of tubulointerstitial inflammation (TII) and tubulointerstitial damage (TID) predicts the progression of chronic kidney disease (CKD) in patients with lupus nephritis (LN). Data from 175 LN patients, collected at the time of renal biopsy, were analyzed. Patients were stratified into two groups based on the presence or absence of coexisting TII/TID. Uni- and multivariable Cox proportional hazard regression models were utilized to identify independent risk factors for CKD in LN patients. Of 175 patients, 110 (62.9%) exhibited coexisting TII/TID, whereas 65 (37.1%) did not. Patients with coexisting TII/TID tended to be older and presented with higher levels of ESR and 24-h proteinuria, as well as lower levels of eGFR and hemoglobin compared to those without coexisting TII/TID. Over a mean follow-up period of 89.9 months, CKD and end-stage renal disease occurred more frequently in patients with coexisting TII/TID. Notably, the presence of coexisting TII/TID was associated with a higher risk of CKD progression, with adjusted hazard ratios of 2.667 (95% CI: 1.333, 5.335, p = 0.006) for all LN patients, 3.265 (95% CI: 1.451, 7.345, p = 0.004) for those with class III, IV, and V LN, and 3.045 (95% CI: 1.289, 7.195, p = 0.011) for those with class III, IV, V LN, and eGFR ≥ 30 mL/min/1.73 m2. LN patients with coexisting TII/TID are at a heightened risk of kidney function deterioration at LN onset and subsequent development of CKD over the long term.

Spectrum of congenital anomalies of the kidney and urinary tract in a pediatric nephrology clinic in Ethiopia and factors associated with advanced chronic kidney disease: A cross-sectional study.

Chronic kidney disease (CKD) is a significant health concern for children with congenital anomalies of the kidney and urinary tract (CAKUT). To address the limited data on CKD prevalence and risk factors in Ethiopia, this study focuses on a specific cohort of CAKUT patients at the pediatric renal unit of Tikur Anbessa specialized hospital. We aim to determine the prevalence of CKD in Ethiopian CAKUT patients, identify independent predictors of advanced stage CKD, and explore the distribution of CKD among different CAKUT phenotypes. Medical charts of children with CAKUT who visited pediatric renal unit were reviewed. Logistic regression analyses were performed to determine the independent predictors of advanced CKD. Statistical significance was set at p ≤ 0.05.The study included 129 male subjects (70.9%). Only 25.3% of CAKUT cases were diagnosed prenatally. About 52.2% of patients had unilateral CAKUT. Posterior urethral valves (PUV) were the most commonly diagnosed CAKUT phenotypes (27.5%). Fifty-three (29.1%) of the patients had CKD, and stage 3 was the most diagnosed CKD (37.7%). CKD development was observed more frequently in patients with isolated PUV (39.6%). Factors like low birthweight, prematurity at birth, and the presence of bilateral CAKUT emerged as independent risk factors for developing advanced stage CKD. This study reveals a significant burden of CKD in children and adolescents with CAKUT. Despite its importance, prenatal CAKUT detection remains low. Posterior urethral valves are the most prevalent phenotype, associated with a higher risk of CKD. The research also highlights independent predictors for advanced CKD development.

Risk Factors for Chronic Kidney Disease in Adult Patients with Congenital Heart Disease and Its Relationship with Cardiovascular Mortality.

Background: Patients with congenital heart disease (CHD) show risk factors for chronic kidney disease (CKD) and it is well known that CKD has a large negative impact on survival. Methods: Observational and prospective cohort study. Adult CHD patients and controls were matched for age and sex. Results: A total of 657 CHD adult patients (cases) and 1954 controls were studied. Median age in CHD patients was 30 (17-62) years and 373 (57%) were male. The prevalence of CKD (Glomerular filtration rate (GFR) < 60 mL/min/1.73 m2) was 0.2% and 4.5% in the control and CHD groups, respectively. Binary logistic regression analysis determined as risk factors for CKD in CHD patients: age [1.54 (1.04-1.28), p = 0.009], dyslipidemia [19.8 (1.35-301.1), p = 0.031], low iron concentration [0.96 (0.96-0.93), p = 0.048], cyanosis [25.7 (1.60-411.8), p = 0.022], and Down syndrome [46.8 (8.09-2710), p = 0.003]. During a follow-up time of 6.8 (1.2-10.5) years, cardiovascular mortality occurred in 31 patients with CHD showing, through the Kaplan-Meier test, a worse outcome among patients with CKD (p < 0.05) as was also seen in the univariate Cox regression survival analysis. However, after adjusting for other variables, this significance was lost, with age remaining as the unique independent prognostic factor. Conclusions: The prevalence of CKD was much higher in patients with CHD than in the control group; age, cyanosis, and Down syndrome were the predictors of a higher risk of CKD among CHD patients. Although CKD was associated with worse survival in CHD patients, only age was identified as an independent prognostic factor for cardiovascular mortality.

Association between chronic kidney disease and cardiovascular disease risk factors in elderly: results from the first phase of Fasa and Shahedieh cohort studies

BackgroundChronic kidney disease (CKD) is associated with increased cardiovascular disease (CVD) risk factors and morbidity in the elderly population. This study aimed to examine the association between CKD and CVD risk factors in the elderly population of Fasa and Yazd (Shahdieh), Iran, using the data from the enrolment phase of Fasa and Shahedieh cohort studies.MethodsWe conducted a cross-sectional analytical study using data from Fasa and Shahedieh cohort studies, which enrolled 1487 and 1507 participants aged over 60 years, respectively. We collected data on demographic and clinical variables, kidney problems, and CVD from the two studies. We estimated the glomerular filtration rate (eGFR) using the modification of diet in renal disease (MDRD) formula and considered values less than 60 ml/min/1.73 m2 as CKD. We used independent t-tests, Spearman’s correlation coefficient, chi-square, one-way analysis of variance, and logistic regression to analyze the data. We performed the analyses using SPSS V. 22.0 software and set the significance level at 0.05.ResultsThe overall prevalence of CKD was 41.9%; 25.7% in women and 16.2% in men. The prevalence of CKD based on reported kidney problems was 1.7%, of which 54.7% were in stage 3 of CKD. Compared to participants in the early stages of CKD, participants in advanced stages had a higher prevalence of diabetes (p < 0.001), hypertension (p < 0.001), ischemic heart disease (IHD) (p < 0.001), and myocardial infarction (p < 0.001). In addition, participants in higher stages of CKD were more obese, had lower physical activity, smoked more, and consumed more opium (p < 0.001).ConclusionOur study showed that more than half of the patients were in stage three CKD, which is an advanced stage of this disease. Diabetes Melitus, hypertension, dyslipidemia, IHD, and myocardial infarction were more prevalent in patients than others. These findings demonstrate the importance of screening for CKD in patients with diabetes mellitus and hypertension. The results also suggest that lifestyle modification and prevention strategies are needed to reduce the burden of CKD and CVD in this population.

A cohort study of correlation between fasting plasma glucose trajectory and new-onset chronic kidney disease in elderly population in Nanjing

Objective: To explore the correlation between fasting plasma glucose (FPG) trajectory and new-onset chronic kidney disease (CKD) in elderly population (≥65 years old) in Nanjing. Methods: The study cohort was composed of 14 763 subjects who met the inclusion criteria in the population in elderly health examination in Nanjing. Based on the FPG levels detected in health examination from 2018 to 2021 (logarithm was used for normal distribution), three different FPG trajectory groups were determined using the SAS Proc Traj program, i.e. low-stable group, medium-stable group, and high-stable group. The incidence of CKD in 2022 was analyzed, and log-rank test was performed to compare the differences of cumulative incidence of new-onset CKD among different trajectory groups. Cox proportional hazards regression model was used to analyze the correlation between different FPG trajectories and new-onset CKD. Results: The mean follow-up time was (416.09±81.96) days. The follow-up time of the 500th day was selected to analyze the cumulative incidence rate of CKD in different FPG trajectory groups, and the cumulative incidence rate of CKD in the low-stable group, the medium-stable group, and the high-stable group of FPG increased with elevated trajectory, which was 15.3%, 21.8%, and 29.3%, respectively (log-rank test χ²=151.16, P<0.001). Cox proportional hazards regression model analysis showed that compared with the low-stable group, the medium-stable group and the high-stable group were all at risk for new-onset CKD. After adjusting for multiple confounding factors, the analysis by Cox proportional hazards regression model 4 indicated that the risk for CKD in medium-stable and high-stable groups were still 1.676 (95%CI: 1.462-1.921) times and 2.007 (95%CI: 1.562-2.579) times higher than that in low-stable group. Conclusions: Elevated FPG change trajectory level is a risk factor for new-onset CKD, and persistently high level of FPG increase the risk for CKD. FPG should be monitored in elderly population by follow up, and individualized prevention and control measures for CKD should be developed for different trajectory groups.

Association of body round index with chronic kidney disease: a population-based cross-sectional study from NHANES 1999-2018.

Complex nexuses between obesity and chronic kidney disease (CKD) have been reported. Nevertheless, the link between the body roundness index (BRI), an indicator utilized to measure body fat distribution, and CKD risk has been unexplored. We utilized publicly available data from ten survey cycles (1999-2018) of the National Health and Nutrition Examination Survey (NHANES) in the United States. We examined the association between BRI and CKD risk using multivariable logistic regression, subgroup analysis, interaction tests, and smooth curve fitting. The study ultimately involved 41,953 participants, 3,123 (7.44%) of whom had CKD. Multivariable logistic regression, adjusted for covariates, identified high BRI levels in quartile 4 as a risk factor for CKD (OR = 1.30, 95% CI 1.12-1.50, P = 0.0005). This association remained consistent across subgroups (P for interaction > 0.05). Smoothed curve fitting exhibited a roughly linear positive correlation between BRI and CKD. According to our study, BRI was related to CKD in a roughly linear way, suggesting a novel indicator for improving prevention and treatment for the CKD population. Nevertheless, additional research is needed to identify the association.

Long-term renal outcomes of children with cancers treated with platinum-based chemotherapy: A retrospective chart analysis.

Platinum-based chemotherapy is a mainstay of treatment for many childhood cancers but is associated with acute nephrotoxicity and long-term ototoxicity. There is emerging evidence of long-term renal complications. This study aimed to assess the prevalence of chronic kidney disease (CKD) in children treated with platinum chemotherapy (cisplatin and carboplatin) and identify potential risk factors for the development of CKD. We conducted a retrospective review of children diagnosed with hepatoblastoma, osteosarcoma, neuroblastoma, or medulloblastoma who received platinum chemotherapy over a 16 year timeframe. Patients were excluded if they did not have at least 3 years follow up data, died within 3 years of platinum chemotherapy, or if they relapsed. Clinical data were collected at baseline (first dose), 1 year, and at most recent follow up. Of 328 treated patients, 147 met the inclusion criteria and were followed for a mean of 8.1 years (range 3-15.7 years). The median age at first dose was 3.7 years (IQR 1.7-9.6 years). CKD ≥grade 2 was present in 53(36%) at last follow up and 15(10%) had tubular dysfunction. A history of acute kidney injury at any time during treatment was associated with CKD (OR 3.12 CI 1.07-9.12, p =0.04). On multivariable analysis older age at platinum therapy (OR 1.2, CI 1.1-1.4, p = 0.004) and a high aminoglycoside or vancomycin trough level (OR 4.3, CI 1.9-9.7, p<0.001) were risk factors for CKD. The high rate of CKD in children treated with platinum chemotherapy warrants long-term follow-up and screening for progressive disease.

Classifying Chronic Kidney Disease Stages Based on Predicted Value of Estimated Glomerular Filtration Rate From Serum Creatinine Levels Using Chronic Kidney Disease Risk Factors and Renal Sinus Anteroposterior Diameter on a Computed Tomography Image.

This study aimed to investigate whether the calculated predicted value of the estimated glomerular filtration rate from serum creatinine levels (eGFRcreat-PV)from multiple regression equations using the anteroposterior diameter of the renal sinus (APDRS) measured on multidetector row computed tomography (MDCT) axial imagesand easily obtainable chronic kidney disease (CKD) risk factors (age and body mass index, BMI) is useful for separating CKD stages. The Review Board approved this study, and the additional approval requirement was waived for this retrospective study. We investigated the association between eGFRcreat and age, BMI, and APDRS using stepwise multivariate regression analysis in 98 patients who underwent MDCT and calculated eGFRcreat-PV from the obtained multiple regression equation. We investigated significant differences in eGFRcreat-PV according to the variation in the CKD stage 3 categories and cutoff value. Additionally, we analyzed the area under the curve (AUC), sensitivity, and specificity of eGFRcreat-PV to differentiate between the patients with greater and less than CKD stage 3. Age, BMI, and APDRS scores were independent factors influencing eGFRcreat. The difference in eGFRcreat-PV between the groups with greater and less than CKD stage 3 was significant. Additionally, the cutoff value, AUC, sensitivity, and specificity of eGFRcreat-PV used to distinguish between the two groups of greater and less than CKD stage 3 were 61.5, 0.801, 63.9%, and 80.6%, respectively. The eGFRcreat-PV from the APDRS, measured on MDCT axial images, along with ageand BMI, helps differentiate the less and more than CKD stage 3.

092. Overview of the Prevalence of Chronic Kidney Disease (CKD) in Kidney and Ureter Stones at Zainoel Abidin Hospital Banda Aceh, 2021

Background: Kidney stones are a predictor and risk factor for CKD and the prevalence rate is 5-10% with comorbid factors which can increase the risk of CKD events. Chronic Kidney Disease (CKD) is a serious complication of urinary tract stones. Chronic kidney disease can occur as a result of urological procedures, obstruction or due to causes inherent in stone formation. Methods: This type of research is descriptive research using secondary data in the form of medical record data. The design of this research is cross sectional with data collection carried out retrospectively. The samples in this study were patients diagnosed with CKD in patients with ureteral stones or kidney stones at Zainoel Abidin Hospital, Banda Aceh. Samples were taken using the total sampling method. Results: In this study, 70 samples were taken and the results of this study based on gender are majority were found to be men 48 samples (68.6%), the most common age category was 41 - 50 years with 28 samples (40.0% ), the most common comorbid factor causing CKD was hypertension in 30 samples (42.5%), the type of urinary tract stones most often found was ureter stones, namely 34 samples (49.0%), and the most common location or urinary tract was ureter stones. bilateral, namely 22 samples (31.4%). Conclusion: The male gender most often experiences CKD due to complications from urinary tract stones, where the age range of 41 - 50 years is the age that experiences the most complications. The most common type of urinary tract stone is ureteral stone with a bilateral location.

Serum Osmolality as a Predictor of Renal Function Decline: A Retrospective Cohort Study.

Background and Aims: Dehydration is a prevalent and costly healthcare concern, linked to heightened risks of acute kidney injury and in-hospital mortality. Despite its significance, limited evidence exists regarding its prevalence and correlation with renal function decline in apparently healthy individuals. This retrospective cohort study aimed to investigate the prevalence and association of dehydration with renal function decline and the development or progression of chronic kidney disease (CKD) in the general population. Methods: The medical records of subjects undergoing annual health check-ups from 2016 to 2019 at a single center in Taiwan were analyzed, and those with CKD stage V, insufficient data, or an increased estimated glomerular filtration rate (eGFR) were excluded. Serum osmolality, eGFR, and relevant parameters were measured. Logistic regression and Kaplan-Meier analyses were used to assess associations between osmolality and CKD-related outcomes. Results: Among the 4449 eligible subjects, those in the higher osmolality quartiles had an elevated risk of CKD or CKD progression. Multivariate analyses identified age, systolic blood pressure, serum osmolality, uric acid, proteinuria, and a history of diabetes as independent risk factors, with high-density lipoprotein being protective. Cumulative incidence curves demonstrated a significant increase in the risk of CKD with increasing osmolality levels. Restricted cubic spline analyses confirmed a nonlinear relationship between osmolality and CKD risk. Conclusions: Elevated serum osmolality independently predicted renal function decline and CKD development in apparently healthy individuals, and this effect persisted after adjusting for established risk factors. Our findings underscore the importance of addressing dehydration as a modifiable risk factor for CKD.

Increased Body Mass Index is Independently Associated with Chronic Kidney Disease among People with Type 2 Diabetes

Background The alarming increase in the prevalence of obesity has implications for chronic kidney disease (CKD) progression in type 2 diabetes (T2D). This study aimed to assess if increased body mass index (BMI) can be an independent risk factor for CKD and T2D in the Indian context. Materials and Methods In this cross-sectional study, 602 (M:F = 378:224) participants were screened using Kidney Disease Improving Global Outcomes (KDIGO) from January to October 2023 in Chennai. Demographic, anthropometric, biochemical, clinical details, and comorbidities were recorded. T2D with CKD low risk was taken as control group, and CKD moderate and high risks were the study groups. BMI was classified based on the Asian criteria into normal (18.5–22.9), overweight (23–24.9), and obese (≥25 kg/m2). Results Majority of participants in moderate and high risk categories were obese compared to the low risk category (60.5% and 66.4% vs. 39.1%; p &lt; 0.001). A higher proportion of participants was on antihypertensive drugs in the high risk group and in the obese category (p &lt; 0.001). Comorbidities and diabetic complications were higher in the high risk group (p &lt; 0.001). Multivariate logistic regression revealed that age of ≥ 60 years [OR(95% CI); 6.3(2.2–18); p = 0.009]; increased BMI as overweight [3.6(2.1–6.3); p &lt; 0.001] and obese [5.2(3.3–8.3); p &lt; 0.001]; smoking [4.2(1.7–10.2); p = 0.002]; increased duration of diabetes of 5–15 years [2.3(1.2–4.5); p = 0.013], 16–25 years [4.8(2.2–10.4); p &lt; 0.001], and &gt;25 years [4.2(1.4–13); p = 0.011]; systolic blood pressure [1.01(1.0–1.03); p = 0.02]; and hemoglobin A1c [1.2(1.1–1.3); p &lt; 0.001] were independent risk factors for the progression of CKD. Conclusion Increased BMI was independently associated with CKD in T2D. Overweight and obese individuals are four to five times at risk for CKD progression. Early identification, lifestyle intervention, and weight-lowering drugs may reduce the complications of obesity in T2D and CKD.

Exploring the potential link between gut microbiota and chronic kidney disease in causality: A 2-sample Mendelian randomization study.

Increasing evidence indicates a significant correlation between gut microbiota (GM) and susceptibility to chronic kidney disease (CKD). However, causal relationship presence remains uncertain. Mendelian randomization (MR) was applied to evaluate potential causal relation from GM to CKD. Genomic association analysis aggregates publicly online databases, utilizing Genome-Wide Association Study (GWAS) database focused on GM and CKD. For examination of potential causal connection from GM to CKD, a 2-way, 2-sample Mendelian randomization (MR) method was applied. Sensitivity analyses were utilized to scrutinize for heterogeneity, horizontal pleiotropy, MR outcomes resilience. Result from inverse variance weighting (IVW) method revealed that 10 microbiotas such as Porphyromonadaceae (OR = 1.351, 95% CI: 1.114-1.638, P = .002), Dorea (OR = 1.236, 95% CI: 1.040-1.468, P = .016), Ruminococcus torques group (OR = 1.290, 95% CI: 1.035-1.608, P = .024) are potential CKD risk factors. Five microbiotas, including the Prevotellaceae (OR = 0.814, 95% CI: 0.719-0.922, P = .001) are potential CKD protective factors. Sensitivity analyses reveal no horizontal pleiotropy or heterogeneity. Additionally, reverse MR results unveiled potential relation between CKD and disorders in 3 microbiotas, including Senegalimassilia. According to the investigation, MR method was employed to delve into reciprocal causal connection from GM to CKD. Our findings identified 15 types of GM causally linked to CKD, as well as CKD demonstrating causal associations with 3 types of GM. Further exploration of these associated GM types is hopeful to raise novel insights, for CKD preventing and early monitoring.

Stenosis of the glomerulotubular neck in progressive chronic kidney disease.

Morphology and morphometric evaluation of lesions beyond conventional parameters can inform the pathophysiology of chronic kidney disease (CKD). We sought to determine whether the occurrence of glomerulotubular neck stenoses associates with progressive CKD. We evaluated the normal parenchyma from radical nephrectomies removed for tumor between 2000 and 2021 and analyzed cortex for stenoses of the glomerulotubular neck. Stenosis of the glomerulotubular neck is defined a focal narrowing for which the draining tubule has a greater diameter than at the neck. Progressive CKD was defined as dialysis, kidney transplantation, sustained eGFR <10 ml/min per 1.73m2 or sustained 40% decline from the post-nephrectomy eGFR. Each case of progressive CKD was age-sex-matched to 2 controls without progressive CKD. Logistic regression models assessed the risk of progressive CKD with stenotic necks adjusting for other histological features, kidney function, and CKD risk factors. There were 65 cases with a mean of 255 glomeruli and 130 controls with a mean of 329 glomeruli. Among both cases and controls, 5% of glomeruli showed visible glomerulotubular necks. The proportion of necks that were stenotic was higher in cases than controls (35% vs. 11%, p<0.0001). Stenotic necks associated with progressive CKD independent of other histologic and clinical characteristics. Glomerulotubular neck stenosis is associated with development of progressive CKD.

Chronic kidney disease and risk factors among Type 2 Diabetic patients in selected hospitals in Dhaka, Bangladesh

Chronic kidney disease (CKD) may be defined as abnormalities of kidney function or structure present for more than 3 months. Around 10% of people worldwide have CKD. The data about chronic kidney disease among diabetics in Bangladesh is inadequate, and very few studies have been done on specific populations, i.e., male or female. Thus, the study aims to determine the prevalence of CKD and its risk factors among diabetic patients in selected hospitals in Dhaka city. The specific objectives of the study were to assess the participants through physical and laboratory evaluations, categorize them into the different stages of CKD, analyze their socio-demographic characteristics, and determine the association between CKD and various risk factors. This is a cross-sectional study. The study population consisted of different outpatient diagnostic centers and outpatient and indoor patients of Shaheed Suhrawardy Medical College and Hospital. The sample size of the study is 369. The Modification of Diet in Renal Disease equation was used to calculate eGFR. This study revealed that in Dhaka, 18.2% of Type 2 Diabetic patients had CKD. Most of the participants were between 46 and 65years old. Most of the CKD patients had a low education level and a lower family income. Having diabetes for more than 3 years and hypertension for more than 5 years were associated with a higher risk of developing CKD, especially among individuals who consumed added salt in their diet.

Adherence to a Healthful Plant-Based Diet and Risk of Chronic Kidney Disease Among Individuals with Diabetes

Objective Chronic kidney disease (CKD) is highly prevalent among people with diabetes. While identifying modifiable risk factors to prevent a decline in kidney function among those living with diabetes is pivotal, there is limited evidence on dietary risk factors for CKD. In this study, we examined the associations between healthy and less healthy plant-based diets (PBDs) and the risk of CKD among those with diabetes, and to identify potential underlying mechanisms. Methods We conducted a prospective analysis among 7,747 UK Biobank participants with prevalent diabetes. Multivariable Cox proportional hazard regression models were used to examine the associations between healthful and unhealthful PBDs and the risk of CKD. Causal mediation analyses were further employed to explore the underlying mechanisms of the observed associations. Results Among 7,747 study participants with diabetes, 1,030 developed incident CKD over 10.2 years of follow-up. Higher adherence to a healthy PBD was associated with a 24% lower CKD risk (HRQ4 versus Q1: 0.76 [95%CI: 0.63–0.92], p trend = 0.002), while higher adherence to an unhealthy PBD was associated with a 35% higher risk (HRQ4 versus Q1: 1.35 [95%CI: 1.11–1.65], p trend = 0.006). The observed associations were predominantly mediated by markers of body fatness (proportion mediated: 11–25%) and kidney function (23–89%). Conclusions In this prospective cohort study of middle-aged adults with diabetes, adherence to a healthy PBD was associated with lower CKD risk, whereas adherence to an unhealthy PBD was associated with a higher CKD risk. Associations were primarily mediated by markers of lower body fatness and improved kidney function.

Optimal tacrolimus levels for reducing CKD risk and the impact of intrapatient variability on CKD and ESRD development following liver transplantation.

This study aimed to identify the risk factors for chronic kidney disease (CKD) and end-stage renal disease (ESRD) following liver transplantation (LT), with a specific focus on tacrolimus levels and intrapatient variability (IPV). Among the 1,076 patients who underwent LT between 2000 and 2018, 952 were included in the analysis. The tacrolimus doses and levels were recorded every 3 months, and the IPV was calculated using the coefficient of variability. The cumulative incidence rates of CKD and ESRD were calculated based on baseline kidney function at the time of LT. The impact of tacrolimus levels and their IPV on the development of CKD and ESRD was evaluated, and the significant risk factors were identified. Within a median follow-up of 97.3 months, the 5-year cumulative incidence rates of CKD (0.58 vs. 0.24) and ESRD (0.07 vs. 0.01) were significantly higher in the acute kidney injury (AKI) group than in the normal glomerular filtration rate (GFR) group. In the normal GFR group, the tacrolimus levels were identified as a risk factor for CKD, with a level of ≤4.5 ng/mL suggested as optimal for minimizing the risk of CKD. Furthermore, the IPV of tacrolimus levels and doses emerged as a significant risk factor for CKD development in both groups (P<0.05), with tenofovir disoproxil fumarate also being a risk factor in HBV-infected patients. The IPV of tacrolimus levels was also a significant factor in ESRD development (P<0.05). This study elucidated the optimal tacrolimus through level and highlighted the impact of IPV on the CKD and ESRD development post-LT.

Characteristics of risk factors and molecular genetic parameters in children with chronic kidney disease

Introduction. Information about the health status of children with nephrological pathology includes many manifestations of functional system disorders. However, early diagnosis of chronic kidney disease (CKD) is rarely carried out due to the lack of reliable predictors of this process.The aim: To analyze the association of anamnestic signs, laboratory and genetic research results with chronic kidney disease in children to identify potential predictors of the disease.Material and Methods. The data were obtained from a single-center retrospective catamnestic cohort study (2011–2022). The main group included 128 children with chronic kidney disease aged 1 to 17 years. The comparison group consisted of 30 children without diagnosed kidney pathology aged from 1 to 17 years. There were no statistically significant differences in sex and age between the two groups. The informative value of more than 150 features, including anamnestic ones, the state of the mother’s health during pregnancy, antenatal and perinatal factors, features of the child’s development and manifestation of the disease, the results of clinical, laboratory, and genetic research methods were evaluated. An integrated approach to the study included methods for hypotheses testing on statistical significance of indicators differences, regression analysis, and ROC analysis.Results. Hereditary burden of nephrological pathology in the family, unfavorable course of pregnancy (anemia, toxicosis of the first half), obstetric and somatic pathology in the mother, the serial number of childbirth are associated with the subsequent development of CKD. Erythrocytes in the urine and daily protein loss were detected only in the group of children with CKD. In this group, a decrease in the number of red blood cells, increased erythrocyte sedimentation rate (ESR), allergies at an early age, otitis media, persistent viral and bacterial infections, and a number of signs of connective tissue dysplasia were more common. The main group statistically significantly differed from the comparison group by a number of polymorphic genetic markers. It can be assumed that the polymorphisms AGT1 Thr174Thr, AGT2 Thr235Thr, NO3 C786T are associated with a predisposition to CKD, and the products of polymorphisms AGT1 Thr174Met, AGT2 Met235Met, R1 AGT2 C1166C, NO3 T786T may have a protective effect according to development of CKD.Conclusion. The risk factors for CKD identified in this study can be used to develop software to support medical decision making for early detection of children at high risk of disease progression.

Analysis of angiotensin II type 1 receptor and osteoprotegerin gene polymorphism on the risk of cardiovascular mortality risk and progressivity of chronic kidney disease.

Chronic kidney disease (CKD) is a significant global public health issue with increased risk of atherosclerotic cardiovascular disease (ASCVD) and cardiovascular mortality. Single nucleotide polymorphisms (SNPs) on angiotensin II type 1 receptor (AT1R) A1166C and osteoprotegerin (OPG) C950T gene have received significant attention as a genetic risk factor for cardiovascular disease and CKD. This was a cross-sectional study involving 75 adults with CKD recruited from Nephrology Outpatient Clinics of Universitas Airlangga Hospital, Surabaya, Indonesia. Demographic data was obtained from interviews and medical records. The "CKD Patch" application was used to asses ASCVD and cardiovascular mortality risk scores. Statistical analysis was performed by using SPSS version 26. We detected four different AT1R gene polymorphisms (A1166C, A1160C, G1170T, and G1181C) and two OPG gene polymorphisms (T950C and G1181C) in Indonesian CKD patients. A1160C and G1181C polymorphisms were novel SNPs, newly discovered in this research. No significant association was found between AT1R SNPs and kidney prognostic markers or ASCVD risk/mortality risk scores. However, for OPG C950T we found that TT genotype had a significantly higher ACR than TC or CC genotype (P=0.032). As for OPG G1181C, we found that GG genotype had a higher serum creatinine and albumin to creatinine ratio compared to GC and CC genotypes (P=0.004 and 0.029, respectively). Genotype GC for OPG G1181C was also shown to be protective for having better kidney markers and lowest cardiovascular mortality risk compared to GG and CC genotypes (P=0.018 and 0.032, respectively). Increased ASCVD risk and mortality risk score was not found on individuals with AT1R gene SNPs. However, for OPG gene polymorphism, C950T and G1181C were associated with kidney progression and cardiovascular mortality.

Study of Hematological Parameters of Children with Chronic Kidney Disease on Hemodialysis and Peritoneal Dialysis in Wasit Governorate

ABSTRACT: The aim of this study was to evaluate some hematological parameters in pediatric patients with chronic kidney disease (CKD) in children who are on hemodialysis (HD) and peritoneal dialysis (PD). It is characterized by its irreversibility. Deterioration of kidney function that gradually progresses to end-stage renal function illness. Over the past two decades, the incidence of CKD in children has increased Steady increase. The major health consequences of CKD include not only progression to kidney failure, but also increased risk of cardiovascular disease. The study was conducted in the dialysis unit of Al-Zahraa Teaching Hospital in Wasit governorate and the Child Protection Teaching Hospital -Medical City in Baghdad. During the period from November 2023 to April 2024. This study aimed to examination of risk factors (height, weight, age, sex, inheritance of the disease in the family, medical history, symptoms of the disease, other diseases, treatment methods) for CKD in general. The biochemical effect was also studied and blood indicators for patients on HD and PD purpose. For the purpose of studying the hematological of patients undergoing dialysis and comparing those results with their values ​​in both HD and PD. This study was done on (80) Iraqi children (30) of them suffering from kidney failure and (50) of them was healthy with age range (1 day -17) years old. HD was performed for 22 children with CKD, and PD was performed for 8 patients with CKD. This study involved dividing patients into three Groups according to the age at which the disease begins, from (1 day-5 years), (6-11) years and (12-17) years, included 15 females and 15 males. Samples were collected based on the incidence of CKD and type of treatment, as well as the diagnosis of all patients according to international standard by the physician. The results of our study with regard to the hematological of patients undergoing PD showed a significant increase in the levels of (WBC) p ≤ 0.05 and also showed a significant decrease in the levels of (RBC, Hb, PCV, ESR) p ≤ 0.05. a non-significant increase in TSH levels p ≥ 0.05. The results of our study with regard to the hematological parameters of patients on HD showed a significant increase in the levels of (ESR) p ≤ 0.05 and a significant decrease in the levels of (WBC, RBC, PCV, Hb) p ≤ 0.05.
