Risk Factors For Chronic Kidney Disease Research Articles

High body mass index and triglyceride levels at health checkups increase the risk of new-onset chronic kidney disease and worsening renal function: the TAMA MED Project-CKD.

Health checkups are important in patients with chronic kidney disease (CKD), which is not easily accompanied by subjective symptoms. CKD can be caused or aggravated by factors that have not yet been identified. This retrospective cohort study included 7 483 patients who underwent specific annual health checkups at a medical institution in Tama City, did not have CKD in 2012, and continued to undergo checkups (aged 40-74years). We examined the risk factors for new-onset CKD and 1.5-fold increase in serum creatinine levels among laboratory values from 2012 to 2020. Age, body mass index (BMI), triglyceride levels, atrial fibrillation, and medication for hypertension (HT) and diabetes mellitus were independent risk factors for proteinuria, whereas current smoking, BMI, systolic blood pressure (SBP), and medication for HT were independent risk factors for estimated glomerular filtration rate < 60mL/min/1.73m2. SBP, triglyceride levels and medication for HT were risk factors for a 1.5-fold increase in serum creatinine levels during course of the study. The cut-off values of BMI for eGFR < 60mL/min/1.73m2 were 22.2 (men 24.7, women 22.1) kg/m2 and fasting triglyceride levels for a 1.5-fold increase in serum creatinine level were 171 (men 247, women 170) mg/dL, respectively. Health checkups provide information to prevent new-onset CKD and worsening of renal function. It is necessary to increase the rate of health checkups and visits to medical institutions after health checkups as well as to use these results for health guidance.

Prevalence and risk factors for chronic kidney disease among older adult patients with schizophrenia in Taiwan.

There is an increasing incidence and prevalence of patients with chronic kidney disease (CKD) worldwide. Little is known the prevalence of CKD among older patients with schizophrenia. The purpose of this study was to investigate the prevalence of CKD and its risk factors in older adults with schizophrenia. In this cross-sectional study, a convenience sample of 240 patients with schizophrenia age 50 or older were recruited. In addition to demographic and clinical data, participants' estimated glomerular filtration rate was calculated using the Modification of Diet in Renal Disease equation based on age, sex, ethnicity, and serum creatinine level determined from a blood sample taken from participants. The overall prevalence of CKD was 11.3%. Those with CKD group were older, had a longer duration of psychiatric illness, a higher body mass index (BMI), and diagnoses of hypertension compared to those in the non-CKD group. Independent of other risk factors, older age and BMI were significantly associated with CKD. This study found that the overall prevalence of CKD in older patients with schizophrenia was 11.3%. Risk factors for CKD in this population were older age and higher BMI. In addition to early identification and early treatment of CKD in older patients with schizophrenia, clinicians should actively manage the risk factors identified in this study, such as higher BMI and older age.

Relationship between parity and the prevalence of chronic kidney disease in Japan considering hypertensive disorders of pregnancy and body mass index.

Global studies exploring the relationship between parity and chronic kidney disease (CKD) are scarce. Furthermore, no study has examined the relationship between parity and CKD in Japan. Therefore, this study aimed to examine the relationship between parity and the prevalence of CKD in a Japanese population, considering the clinical history of hypertensive disorders of pregnancy (HDP) and current body mass index (BMI) based on menopausal status. This cross-sectional study included 26,945 Japanese multiparous women (5,006 premenopausal and 21,939 postmenopausal women) and 3,247 nulliparous women (1,599 premenopausal and 1,648 postmenopausal women). Participants were divided into two groups based on their menopausal status (premenopausal and postmenopausal women). The relationship between parity and the prevalence of CKD was evaluated using a multiple logistic regression model adjusted for several covariates, including a clinical history of HDP and current BMI. The relationship between parity and the prevalence of CKD was not statistically significant in either premenopausal or postmenopausal multiparous women. A clinical history of HDP was significantly associated with an increased risk of CKD in premenopausal and postmenopausal multiparous women. However, the relationship between a clinical history of HDP and CKD in premenopausal women was weakened after adjusting for current BMI. Furthermore, the current BMI was significantly associated with an increased risk of CKD in both premenopausal and postmenopausal women. Parity is not significantly associated with the prevalence of CKD in premenopausal and postmenopausal multiparous women. A clinical history of HDP is a risk factor for CKD in both premenopausal and postmenopausal women. Current BMI is also associated with an increased risk of CKD in premenopausal and postmenopausal women. Therefore, continuous surveillance and preventive measures against CKD should be provided to women with a clinical history of HDP. In addition, maintaining an appropriate body weight is beneficial in reducing the risk of CKD.

Neutrophil-to-lymphocyte ratio associated with renal function in type 2 diabetic patients.

Type 2 diabetes mellitus (T2DM) is a leading risk factor for the development and progression of chronic kidney disease (CKD). However, an accurate and convenient marker for early detection and appropriate management of CKD in individuals with T2DM is limited. Recent studies have demonstrated a strong correlation between the neutrophil-to-lymphocyte ratio (NLR) and CKD. Nonetheless, the predictive value of NLR for renal damage in type 2 diabetic patients remains understudied. To investigate the relationship between NLR and renal function in T2DM patients. This study included 1040 adults aged 65 or older with T2DM from Shanghai's Community Health Service Center. The total number of neutrophils and lymphocytes was detected, and NLR levels were calculated. CKD was defined as an estimated glomerular filtration rate ≤ 60 mL/min/1.73 m². Participants were divided into four groups based on NLR levels. The clinical data and biochemical characteristics were compared among groups. A multivariate logistic regression model was used to analyze the association between NLR levels and CKD. Significant differences were found in terms of sex, serum creatinine, blood urea nitrogen, total cholesterol, and low-density lipoprotein cholesterol among patients with T2DM in different NLR groups (P < 0.0007). T2DM patients in the highest NLR quartile had a higher prevalence of CKD (P for trend = 0.0011). Multivariate logistic regression analysis indicated that a high NLR was an independent risk factor for CKD in T2DM patients even after adjustment for important clinical and pathological parameters (P = 0.0001, odds ratio = 1.41, 95% confidence intervals: 1.18-1.68). An elevated NLR in patients with T2DM is associated with higher prevalence of CKD, suggesting that it could be a marker for the detection and evaluation of diabetic kidney disease.

Possible sarcopenia and risk of chronic kidney disease: a four-year follow-up study and Mendelian randomization analysis

ABSTRACT Introduction Chronic kidney disease (CKD) is a common risk factor for sarcopenia. However, whether sarcopenia increases the risk of CKD remains unclear. To investigate the longitudinal and causal associations between possible sarcopenia and CKD, this study was performed. Methods Possible sarcopenia was defined according to the Asian Working Group for Sarcopenia in 2019. Participants aged ≥ 40 years were recruited from the baseline survey of the China Health and Retirement Longitudinal Study and followed up for four years. Binary logistic regression was used to evaluate the cross-sectional and longitudinal associations between possible sarcopenia, low muscle strength, low physical performance and CKD. Propensity score matching was used to balance the intergroup differences. Subgroup and interactive analyses were adopted to identify potential interactive effects. Mendelian Randomization analysis was used to assess the causal association between appendicular lean mass (ALM) and CKD. Results After data cleansing, a total of 7296 participants were included in the baseline survey. In the cross-sectional analyses, the odds ratios (ORs) of prevalent CKD were 1.50 (95% CI = 1.23–1.84, p < 0.001) for possible sarcopenia, 1.37 (95% CI = 1.10–1.70, p < 0.01) for low muscle strength and 1.42 (95% CI = 1.16–1.74, p < 0.001) for low physical performance in the full models. No significant interaction effects of covariates were detected (all P for interaction > 0.05). After four years of follow-up, an increased risk of incident CKD was also observed in participants with possible sarcopenia (OR = 1.66, 95% CI = 1.13–2.44, p = 0.010) and low physical performance (OR = 1.69, 95% CI = 1.16–2.45, p = 0.006), but not in participants with low muscle strength (OR = 1.19, 95% CI = 0.75–1.88, p = 0.469). In the Mendelian Randomization analysis, the inverse variance weighted estimator showed that a 1-standard deviation increase of genetically predicted ALM was associated with a lower risk of CKD (OR = 0.92, 95% CI = 0.85–0.99, p = 0.035). All the sensitivity analyses supported the main findings. Conclusions Possible sarcopenia is an independent risk factor for CKD and may serve as a predictor of CKD for early identification and intervention.

Terpenes in the management of chronic kidney disease.

Chronic kidney disease (CKD) is a chronic and progressive systemic condition that characterizes irreversible alterations in the kidneys' function and structure over an extended period, spanning months to years. CKD is the one of the major causes of mortality worldwide. However, very limited treatment options are available in the market for management of the CKD. Diabetes and hypertension are the key risk factors for the progression of CKD. It is majorly characterised by glomerulosclerosis, tubular atrophy, and interstitial fibrosis. Plants are considered safe and effective in treating various chronic conditions. A diverse group of phytoconstituents, including polyphenols, flavonoids, alkaloids, tannins, saponins, and terpenes, have found significant benefits in managing chronic ailments. Terpenes constitute a diverse group of plant compounds with various therapeutic benefits. Evidence-based pharmacological studies underscore the crucial role played by terpenes in preventing and managing CKD. These substances demonstrate the capacity to hinder detrimental pathways, such as oxidative stress, inflammation and fibrosis, thereby demonstrating benefit in renal dysfunction. This review offers a comprehensive overview of the roles and positive attributes of commonly occurring terpenes in managing the causes and risk factors of CKD and the associated conditions.

The association between circadian syndrome and chronic kidney disease in an aging population: a 4-year follow-up study.

Circadian syndrome (CircS) is proposed as a novel risk cluster based on reduced sleep duration, abdominal obesity, depression, hypertension, dyslipidemia and hyperglycemia. However, the association between CircS and chronic kidney disease (CKD) remains unclear. To investigate the cross-sectional and longitudinal association between CircS and CKD, this study was performed. A national prospective cohort (China Health and Retirement Longitudinal Study, CHARLS) was used in this study. To define CKD, the estimated glomerular filtration rate (eGFR) was calculated based on the 2012 CKD-EPI creatinine-cystatin C equation. Participants with eGFR <60 mL.min-1/1.73/m2 were diagnosed with CKD. Multivariate binary logistic regression was used to assess the cross-sectional association between CircS and CKD. Subgroup and interactive analyses were performed to determine the interactive effects of covariates. In the sensitivity analysis, the obese population was excluded and another method for calculating the eGFR was used to verify the robustness of previous findings. In addition, participants without CKD at baseline were followed up for four years to investigate the longitudinal relationship between CircS and CKD. A total of 6355 participants were included in this study. In the full model, CircS was positively associated with CKD (OR = 1.28, 95% CI = 1.04-1.59, P < 0.05). As per one increase of CircS components, there was a 1.11-fold (95% CI = 1.04-1.18, P < 0.05) risk of prevalent CKD in the full model. A significant interactive effect of hyperuricemia in the CircS-CKD association (P for interaction < 0.01) was observed. Sensitivity analyses excluding the obese population and using the 2009 CKD-EPI creatinine equation to diagnose CKD supported the positive correlation between CircS and CKD. In the 2011-2015 follow-up cohort, the CircS group had a 2.18-fold risk of incident CKD (95% CI= 1.33-3.58, P < 0.01) in the full model. The OR was 1.29 (95% CI = 1.10-1.51, P < 0.001) with per one increase of CircS components. CircS is a risk factor for CKD and may serve as a predictor of CKD for early identification and intervention.

Ambient Air Pollution and Chronic kidney disease risk in Deltan communities: A Policy Brief, 2023

Chronic kidney disease (CKD) is a persistent, devastating, yet neglected, non-communicable disease in developing and emerging countries. National, regional, and international agencies’ communications and reports on non-communicable diseases intentionally or non-intentionally do not feature CKD. The traditional risk factors for CKD, such as hypertension and diabetes, which have received relatively ample attention, do not sufficiently explain the high burden of CKD in these countries. Ambient air pollution is an emerging significant environmental risk factor for CKD; however, epidemiological data and evidence are lacking for susceptible populations in developing countries. The Niger Delta region of Nigeria is a petrochemical hub known for environmental degradation, including air pollution, and thus, serves as a good case study for investigating the association between air pollution and CKD. This brief is based on the results of a mixed-methods study conducted in four communities situated near an oil and gas refinery in Warri, Nigeria. Air pollutant concentrations measured in partnership with citizen scientists showed that all except one air pollutant (ozone) exceeded the WHO acceptable limits in all four communities. The overall prevalence of CKD was high (12.3%) but even higher (18%) in a socially deprived semi-urban community closest to the oil refinery. Hypertension, diabetes, other behavioral risk factors, and exposures associated with CKD were prevalent among the inhabitants of the four communities. However, public environmental health information and education are lacking. A multifaceted approach is required to mitigate air pollution and the associated health risks in the state. Public inclusion is strongly recommended for the planning and implementation of future interventions. Kidney disease prevention and treatment should be emphasized in health policies and insurance schemes.

Diets high in subsidized foods and chronic kidney disease in Hispanic communities in the United States: the Hispanic Community Health Study/Study of Latinos.

Prior research shows that diets high in government subsidized foods may be associated with cardiometabolic disease risk factors. Our aim was to evaluate the relationship between diets high in subsidized foods and the development of chronic kidney disease (CKD) and other cardiometabolic risk factors in United States (US) Hispanics/Latinos. Using data from 16,172 Hispanics/Latino's living in the United States, we used the Cochran-Armitage test to assess the relationship between subsidized foods in the diets of participants and baseline characteristics. We used survey-weighted Poisson regression models to examine whether intake of subsidized foods was associated with incident CKD or cardiometabolic risk factors. Several baseline characteristics were associated with higher subsidized food scores. Higher subsidized food scores were not associated with incident CKD or cardiometabolic risk factors. These findings may be useful for future researchers, clinicians, and nutritional policy advocates who are interested in the way Hispanic and Latinos consume foods subsidized by the US government and the structural factors that may shape observed dietary and disease patterns.

Exploration of Risk Factors of the Onset of Antibiotics-induced Acute Kidney Injury and Its Transfer to Chronic Kidney Disease Using the Medical Information Database

Drug-induced acute kidney injury (AKI) is a serious adverse drug reaction, which results in a significant decline in renal function and is known to progress to chronic kidney disease (CKD). Therefore, appropriate drug therapy is important to avoid the risk of drug-induced AKI and CKD, which are serious concerns in clinical practice. In this study, using the medical information database of Hamamatsu University Hospital, we investigated the risk factors that accelerate the onset of drug-induced AKI or its progression to CKD in patients who received aminoglycoside antibiotics (AGs) or glycopeptide antibiotics (GPs), which are strongly associated with drug-induced AKI and CKD. We performed logistic regression analysis using patients' background, laboratory test results, and concomitant drug use, among other such factors as explanatory variables and drug-induced AKI or CKD onset as objective variables to explore the risk factors for drug-induced AKI and CKD. Our results showed that co-administration of amphotericin B, piperacillin-tazobactam and other AGs and GPs, increased serum creatinine (Scr) and chloride concentrations, serum lactate dehydrogenase activity, and decreased serum albumin concentration were risk factors for drug-induced AKI onset. Moreover, a reduced blood urea nitrogen:Scr ratio at drug-induced AKI onset served as a risk factor for CKD. These results suggest that careful monitoring of the aforementioned factors is important to ensure appropriate usage of these drugs in patients treated with AGs and GPs.

Community pharmacist-led point-of-care eGFR screening: early detection of chronic kidney disease in high-risk patients

Adherence to scheduled physician screenings for renal function monitoring in patients with chronic kidney disease (CKD) or those at high risk remains suboptimal despite the endorsement of regular screenings by several clinical practice guidelines. Our study aims to assess the effectiveness of a point-of-care CKD screening program led by these pharmacists using the PICCOLO device while recognizing the unique position of community pharmacists in primary care. We conducted an 11-month prospective point-of-care interventional research study in the United Arab Emirates to evaluate the performance of a community pharmacist-led CKD screening program for high-risk patients. Six diverse community pharmacies were selected based on staff availability, patient volume, and their offered range of services. Eligible individuals with risk factors for CKD were identified during medication evaluations. The PICCOLO Comprehensive Metabolic Panel facilitated on-site blood analysis, delivering estimated Glomerular Filtration Rate (eGFR) results within 10 to 15 min. Data also included eGFR categories, demographic information, and insights into lifestyle and health habits collected through a questionnaire. Pharmacists conducted comprehensive medication reviews and offered referrals and lifestyle guidance as part of the program. The study encompassed a total of 400 patients, with an average age of 69 ± 13.4 years within the study cohort. Notably, 38.8% (155 individuals) of the 400 patients were found to have undiagnosed CKD stages 3–5. Univariate logistic regression analysis revealed a significant association between a higher incidence of CKD stages 3–5 and factors such as older age, a history of hypertension, vascular disease, and diabetes mellitus. In the multivariate regression model, age and a history of diabetes mellitus emerged as significant predictors of an elevated risk of CKD. This study sheds light on the viability and impact of CKD screening programs conducted by community pharmacists, particularly in detecting CKD stages 3–5. The findings have implications for healthcare policies, as they can influence the enhancement of early detection and management of CKD. Moreover, these insights may catalyze focused screening initiatives and strengthen collaboration between community pharmacies and healthcare systems to benefit patients at high risk of CKD.

Serum Homocysteine and Folic Acid Levels as Risk Factors of Chronic Kidney Disease

Chronic kidney disease (CKD) is a worldwide health problem. Homocysteine (Hcy) and folic acid (FA) have been found to correlate with intra-renal atherosclerosis, which leads to decreased renal perfusion pressure and may impair the endothelial function of renal arterioles and glomerular capillaries, thus being considered as new risk factors for CKD. Objective: To investigate serum Hcy and FA as risk factors for CKD. Methods: A cross-sectional study was conducted on 80 patients who underwent creatinine examination. Hcy and FA levels were examined using enzyme-linked immunosorbent assay (ELISA) method. Bivariate analysis to calculate the prevalence ratio (PR) using a 2x2 table and using Receiver Operating Characteristic (ROC) curves to determine the cut off value of HCY and FA in CKD. Results: The mean Hcy level of CKD patients was 7.66±4.25 µmol/L and without CKD was 4.29 ± 2.71 µmol/L. The mean FA levels of CKD and non-CKD patients were 6.75±1.75 and 9.27±9.28 ng/mL, respectively. The prevalence ratio of Hcy to CKD was 2.17 (95%CI=1.35-3.45; p=0.001). The prevalence ratio of FA to CKD was 1.75 (95%CI=1.11-2.75; p 0.014). Conclusion: Increased Hcy levels and decreased serum FA levels are risk factors for CKD.

Abstract P416: Higher Household Income is Protective Against Chronic Kidney Disease Among White but Not Black Adults: An Analysis of 2017-2020 NHANES

Introduction: Chronic kidney disease (CKD) disproportionately affects Black adults in the U.S. Prior work suggests that lower income is a risk factor for CKD among Black but not White adults; however, this has not been examined in a nationally representative population, using the updated, race-free kidney function equation. Objective: To examine the relationship between household income and CKD between Black and White adults. Methods: We used data from the 2017-2020 NHANES. CKD was defined as an estimated glomerular filtration rate (eGFR) &lt; 60 mL/min/1.73m 2 based on the race-free CKD-EPI equation and/or a urine albumin-creatinine ratio &gt;30 mg/g. The poverty income ratio (PIR) (ranging from 0 to ≥5) was reported in NHANES (calculated as a multiple of interviewees self-reported income in dollars as compared to the federal poverty line). We examined the association between PIR and CKD using survey-weighted Poisson regression models, adjusted for age, sex, education, marital status, and medical comorbidities. We also examined how this association differed between Black and White adults aged ≥18 years old in separate subgroup analyses via interaction terms. Results: The weighted sample was 51.7% female, 15.5% Black, and 84.5% White with mean age (±SE) of 47.5±0.3 years. In the total sample, and among White adults, higher household income was associated with a lower prevalence of CKD ( Table ). A one-unit higher PIR was associated with a 11% (95% CI: 5%, 16%) lower prevalence of CKD in the total sample and a 12% (95% CI: 6%, 18%) lower prevalence of CKD among White adults. However, this association was not significant for Black adults. The interaction term for race and income was significant ( P = 0.001). Conclusion: Higher income was associated with a lower risk of CKD among White, but not Black adults. Further work is needed to characterize the complex relationship between socioeconomic status and race to address disparities in CKD.

Abstract MP16: Degree of Joint Risk Factor Control and Incident Chronic Kidney Disease Among Obese Individuals

Introduction: Individuals who are obese are at a higher risk for chronic kidney disease (CKD) than the non-obese population. Hypothesis: We assessed the hypothesis that controlling joint risk factors might reduce the increased risk of CKD observed in participants with obesity. Methods: We included a total of 97,538 participants who were obese at baseline and matched 97,538 normal weight control participants from the UK Biobank in the analysis. The degree of joint risk factor control was assessed based on 6 major CKD risk factors, including blood pressure, hemoglobin A1c, low-density lipoprotein cholesterol, albuminuria, smoking, and physical activity. The Cox proportional hazards models were used to estimate associations between the degree of risk factor control and risk of CKD. Results: Among obese participants, joint risk factor control showed an association with a stepwise reduction of incident CKD risk. Each additional risk factor control corresponded to an 11% (HR: 0.89, 95%CI: 0.86-0.91) reduced risk of CKD among obese participants; with the optimal controlling of all six risk factors associated with a 49% (HR: 0.51, 95% CI: 0.43-0.61) decrease in risk of CKD. Furthermore, in obese individuals who jointly controlled all six risk factors, the excess risk of CKD associated with obesity was effectively neutralized compared to normal weight control subjects. Notably, the protective correlations between the degree of joint risk factor control and the incidence of CKD were more pronounced in men compared to women, in individuals with a lower healthy food score versus a higher score, and among diabetes medication users as opposed to nonusers ( P for interaction=0.017, 0.033, 0.014 respectively). Conclusion: The joint risk factor control is associated with an inverse association of CKD risk in an accumulative manner among obese people. Achieving ideal control over risk factors may effectively counterbalance the excessive risk of CKD typically associated with obesity.

The Fatty Liver Index's Association with Incident Chronic Kidney Disease in Korean Middle-Aged Adults: A Community-Based Cohort Study.

(1) Background: The relationship between nonalcoholic fatty liver disease (NAFLD) and incident chronic kidney disease (CKD) is unclear, and long-term follow-up data are limited. Therefore, this study aimed to evaluate whether NAFLD, as assessed by the fatty liver index (FLI), could predict the development of CKD in a community-based Korean cohort over 16 years. (2) Methods: Among the 10,030 total participants, 7778 patients without CKD were selected from the Korean Genome and Epidemiology Study (KoGES). The FLI grade ranged from 0 to 100 and was divided into three groups: low (FLI, <30), intermediate (FLI, 30-59), and high (FLI, ≥60). An estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2 or the development of proteinuria was considered to indicate incident CKD. (3) Results: During the 16-year follow-up period, 919 individuals (11.8%) developed CKD. The HRs of incident CKD in the intermediate FLI group (30-59) and high FLI group (≥60) increased compared with the reference low FLI group (<30) after adjusting for potentially confounding variables. NAFLD, as assessed by the FLI, was an independent risk factor for CKD. (4) Conclusions: Our findings suggest that the FLI, a simple surrogate biomarker of fatty liver disease, may be used to identify people at high risk of incident CKD in clinical practice.

Association between blood pressure variability and risk of kidney function decline in hypertensive patients without chronic kidney disease: a post hoc analysis of Systolic Blood Pressure Intervention Trial study.

Blood pressure variability (BPV) is a risk factor for poor kidney function independent of blood pressure (BP) in chronic kidney disease (CKD). Little is known about the association between kidney function decline and BPV in hypertensive patients without CKD. A post-hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT) was performed. BPV was measured as standard deviation (SD) and average real variability (ARV). Cox proportional hazard models were employed to explore the relationship between BPV and incident CKD and albuminuria. A total of 5700 patients were included, with a mean age of 66.4 years old. During a median of 3.29 years follow-up, 150 (2.6%) patients developed CKD and 222 (7.2%) patients developed albuminuria. Patients were divided into four groups according to the quartiles of BPV. Compared with SBPV Q1, the incidence of CKD was higher in SBPV Q2-Q4; hazard ratios and 95% confidence interval were 1.81 (1.07-3.04), 1.85 (1.10-3.12) and 1.90 (1.13-3.19), respectively. The association between incident CKD and albuminuria with DBPV was less significant than SBPV. Similar results were found when measuring BPV as ARV and SD. No interaction was detected in BP-lowering strategy and SBPV on incident CKD and albuminuria (P > 0.05). This study found that BPV was a risk factor for incident CKD and albuminuria in patients without CKD, especially SBPV. Although intensive BP control increased the risk of CKD, the association between SBPV and kidney function decline did not differ between the two treatment groups.

Association of body mass index with coronary artery disease and chronic kidney disease: An autopsy study

BackgroundBody mass index (BMI) is a critical determinant of mortality, and higher BMI is associated with coronary artery disease (CAD) and chronic kidney disease (CKD). MethodsAn autopsy-based prospective descriptive pilot study conducted over 02 years. All the cases of age between 18 and 70 years without any known comorbidities were considered for the study. BMI was calculated and during autopsy heart was examined for any coronary artery stenosis and kidney were examined grossly and sent for histopathology examination. ResultsThis study has a male predominance, with 73.1 % male and 26.9 % female. Maximum cases were in age group 51–60 years (25 %). 60.6 % cases were in normal BMI and 39.4 % cases were in abnormal BMI. Left anterior descending artery (LAD) was the most commonly involved artery with stenosis >50 %. Glomerulosclerosis was present in 8.65 % cases and tubular atrophy was present in 6.73 % cases. When normal BMI vs abnormal BMI was compared with LAD (p 0.00), LCX (p 0.01) and RCA (p 0.01) stenosis, tubular atrophy (p 0.05), strong association was found and when compared with glomerulosclerosis (p 0.13) no association was found. ConclusionsThere is a strong connection between BMI and both CAD and CKD, although the degree and nature of these connections can vary depending on several factors. To have complete assessment of one's risk factors for CAD and CKD, it is crucial to undergo regular health check-ups and engage in conversations with healthcare professional.

Incidence and Risk Factors Associated With Chronic Kidney Disease After Liver Transplantation: A Review of a 20-Year Experience at a Single Center

Chronic kidney disease (CKD) is one of the major complications after liver transplantation (LT), with a significant impact on patient outcomes. This study aims to investigate the incidence and risk factors of CKD in LT recipients at Siriraj Hospital over the past 20 years. There were 366 adult patients undergoing LT at Siriraj Hospital between January 2002 and December 2021. After excluding patients with pretransplant CKD stages 4 to 5, simultaneous liver-kidney transplantation, and patients who died after LT within 90 days, we retrospectively reviewed a total of 288 patients. Univariable and multivariable binary logistic regression analyses were used to identify the risk factors of post-transplant CKD. Of the 288 patients, 171 (59.4%) developed CKD after LT. The median time to develop CKD was 5.8 months (IQR, 3.8-15.3). Univariable and multivariable analyses revealed that age ≥55 years (odds ratio [OR] = 2.44; 95% CI, 1.34-4.42; P = .003), pretransplant kidney dysfunction defined as estimated glomerular filtration rate <60 mL/min/1.73 m2 (OR = 2.23; 95% CI, 1.16-4.27; P = .016), and postoperative acute kidney injury (OR = 3.06; 95% CI, 1.73-5.42; P < .001) were significantly associated with post-transplant CKD. Patients with preexisting kidney dysfunction who received delayed calcineurin inhibitor introduction without antibody induction protocol had a significantly lower incidence of post-transplant CKD (OR = 0.28; 95% CI, 0.11-0.70; P = .007). Advanced age, pre-transplant kidney dysfunction, and postoperative acute kidney injury are risk factors for CKD after LT. Importantly, delayed calcineurin inhibitor introduction can protect patients with pretransplant kidney dysfunction from developing post-transplant CKD. These results may have important clinical implications in reducing the incidence of CKD after LT.

Exploring multifaceted factors in chronic kidney disease risk: A comprehensive analysis of biochemistry, lifestyle, and inflammation in elderly Chinese individuals.

This letter praises a recent article in the World Journal of Clinical Cases (Roles of biochemistry data, lifestyle, and inflammation in identifying abnormal renal function in old Chinese), examining factors affecting abnormal renal function in elderly Chinese using advanced machine learning. It highlights the importance of uric acid, age, hemoglobin, body mass index, sport hours, and systolic blood pressure. The study's holistic approach, integrating lifestyle and inflammation, offers a nuanced understanding of chronic kidney disease risk factors. The letter suggests exploring mechanistic pathways of hyperuricemia, the link between anemia and renal function, and the connection between body mass index and estimated glomerular filtration rate. It advocates investigating physical activity's impact on renal health and the independent effects of blood pressure. The study significantly contributes to chronic kidney disease understanding, proposing avenues for further exploration and interventions. Commendations are extended to the authors and the journal.

Risk factors for Undiagnosed Kidney Disease among Stable First-Degree Relatives of Chronic Kidney Disease Patients at Nnamdi Azikiwe University Teaching Hospital, Nnewi, South Eastern Nigeria

Background: Chronic kidney disease (CKD) is a global public health problem and has a major impact on health and cost of health care. In Nigeria, renal replacement therapy (RRT) is funded out of pockets by patients and their relatives unlike in most developed countries. There is a high clustering of the risk factors for CKD in FDRs of CKD patients, making then an ideal population for the screening for and the reversal of the modifiable risk factors that predispose to CKD.&#x0D; Objective: This study determined the risk factors for CKD in the FDRs of patients&#x0D; Methodology: This study involving 300 subjects: 150 FDRs of CKD patients and 150 control subjects without personal or family history of CKD. The study and control subjects were screened for CKD using urine albumin creatinine ratio (uACR) and estimated glomerular filtration rate (eGFR). Prevalence rate of the risk factors for CKD such as hypertension, diabetes mellitus, obesity, dyslipidaemia, hyperuricaemia and life style practices like significant smoking and heavy alcohol consumption were determined for both the FDRs and the control subjects. Data was analyzed with SPSS version 21.0. Mann-Whitney U test was used for comparing the variables between the two study groups for continuous variables that were not normally distributed and Chi square tests for categorical variables.&#x0D; Results: The prevalence rate of dyslipidaemia and hyperuricaemia was significantly higher among the FDRs of CKD patients compared with the control subjects (26% versus 12%; P = 0.003) and (20.7% versus 7.3%; P = 0.001) respectively. The other risk factors for CKD that included hypertension, diabetes mellitus, obesity, significant cigarette smoking, heavy alcohol consumption and herbal medication use were equally more among the FDRs of CKD patients compared with the controls, although not statistically significant.&#x0D; Conclusion: The risk factors for CKD were common among FDRs of CKD patients. Screening for these risk factors at the earliest possible contact with the FDRs of CKD patients and taking appropriate actions to tackle the modifiable ones will prevent the development of CKD and retard the progression of the already existing disease, reduce the alarming global burden of CKD.
