Limited Knowledge of Chronic Kidney Disease among Type 2 Diabetes Mellitus Patients in India

Risk factors associated with Indian type 2 diabetes patients with chronic kidney disease: CITE study, a cross-sectional, real-world, observational study

BACKGROUND

Type 2 diabetes (T2DM) is the leading cause of chronic kidney disease (CKD) worldwide. Identifying clinical and laboratory associations with chronic kidney disease (CKD) in type 2 diabetes (T2DM) can help physicians target modifiable risk factors. In light of limited data from India, the CITE (CKD in Indian T2DM Evaluation) study was conducted.

METHODS

The multicenter, cross-sectional CITE study included 3,325 patients from 28 centres across India over a three-month period. CKD was defined as a persistent decline in kidney function (eGFR < 60 ml/min/1.73 m² for ≥ 3 months) or an elevated urine albumin-to-creatinine ratio (UACR) in at least two samples. Descriptive statistics summarised patient characteristics, while logistic regression analyses identified significant risk factors for CKD.

RESULTS

The prevalence of CKD in T2DM was 32%, with a median patient age of 59.9 years and 60.72% having a T2DM duration > 10 years. Reduced eGFR (< 60 ml/min/1.73 m²) was associated with older age (OR: 2.47, 95% CI 2.11-2.88, P < 0.001), longer T2DM duration (OR: 2.28, 95% CI 1.77-2.93, P < 0.001), higher HbA1c (OR: 1.039, 95% CI 1.001-1.079, P = 0.046), and elevated SBP (OR: 1.005, 95% CI 1.002-1.009, P = 0.003). Macroalbuminuria (UACR > 300 mg/g) was linked to non-vegetarian diet (OR: 1.95, 95% CI: 1.59-2.40, P < 0.001) and tobacco use (OR: 1.42, 95% CI: 1.17-1.73, P < 0.001). CKD increased comorbidity odds.

CONCLUSION

The CITE study highlights the prevalence of CKD (32%) in Indian patients with T2DM and identifies clinical and laboratory factors associated with CKD, including age ≥ 60 years, T2DM duration, SBP, HbA1c, tobacco use, non-vegetarian diet, and comorbidities. Longitudinal studies are needed to confirm these associations and evaluate causality.

Contrast-Induced Nephropathy in Endovascular Patients: A Retrospective Cohort Study from a Vascular Surgery Clinic in Eastern Europe

Introduction: Contrast-induced nephropathy (CIN) has emerged as a prevalent and serious complication associated with the administration of iodinated contrast media during diagnostic and therapeutic procedures. Given the rising global prevalence of chronic kidney disease(CKD,) it is crucial to gain a deeper understanding of the risks linked to contrast media exposure. Therefore, the aim of this study, conducted at the Vascular Surgery Clinic in a tertiary hospital in Eastern Europe (Timisoara, Romania), is to assess the incidence of CIN and identify its associated risk factors among patients undergoing endovascular interventions. Methods: This retrospective cohort study was conducted using data from patients treated at a vascular surgery clinic in Timisoara, Romania, between 1 January 2018 and 31 December 2023. The study population included adult patients who underwent scheduled endovascular procedures and had serum creatinine measurements both before and after the procedure. Results: A total of 331 patients were included in the analysis (71.42% males with a mean age of 66.79 ± 9.86 years). In total, 9.22% of the patients had CKD, while 23.8% developed CIN. The mean age was significantly higher in the CIN group (68.4 years) compared to the non-CIN group (66.32 years) with a p-value of 0.093, indicating that older age is associated with a higher risk of CIN. A multivariate logistic regression analysis was performed to assess the association between various factors and the development of CIN. Higher hemoglobin levels were associated with reduced odds of CIN (OR = 0.792, 95% CI: 0.659-0.952, p = 0.0148), indicating that anemia is a significant risk factor for CIN, while CKD significantly increased the odds of CIN by 85.8% (OR = 1.858, 95% CI: 1.105-3.125, p = 0.0023), establishing CKD as a critical risk factor for CIN. Conclusions: While anemia and CKD were found to be significant predictors of CIN, further research on a wider population is required to validate these findings and explore additional risk factors. Our study shows that, in the context of elective endovascular procedures, addressing anemia correction and stabilizing creatinine levels to baseline represents a crucial strategy for reducing the risk of CIN.

Assessment of Patient Awareness Regarding Chronic Kidney Disease Management in Santhal Parganas

Background

Chronic kidney disease (CKD) is a global health challenge, and effective self-management is crucial for optimal outcomes. Assessing the prevailing knowledge about CKD in patients can help strategies information education communication program to better manage the disease. This study evaluated the current knowledge of self-management of CKD among patients suffering from CKD in Santhal Parganas of Jharkhand state in India.

Materials and Methods

This cross-sectional survey was conducted in a tertiary care teaching hospital situated in Deoghar, Jharkhand, India from June to December 2023. Patients suffering from CKD were enrolled for this study from the Outpatient Department. The Chronic Kidney Disease Self-Management Knowledge Tool (CKD-SMKT) was used to measure patients' knowledge through face-to-face interviews conducted by a trained local surveyor.

Results

A total of 228 patients with a mean age of 52.63±10.65 years (men 136 [59.65%], women 92 [40.35%]) participated in the survey. All the patients (100%) gained knowledge about CKD from doctors, followed by other patients (63.6%) and relatives (41.23%). On average, 53.61% did not have proper knowledge about overall kidney disease. Correct knowledge about maintaining kidney health was among 38.1% of patients with 36.59% unsure about their knowledge and 25.31% declaring their lack of knowledge.

Conclusion

A low level of knowledge about kidney health was found among the patients suffering from CKD in Santhal Parganas, a region with a tribal population with a low literacy rate. The identified knowledge gap emphasizes the need for a tailored educational program for CKD patients by doctors and patients relative.

Chronic Kidney Disease Preventive Attitude, Practice, and Associated Factors among Type 2 DM Patients in Ethiopia: A Cross-Sectional Study

Introduction

Globally, chronic kidney disease (CKD) has emerged as one of the leading causes of mortality and it is one of a small number of noncommunicable diseases that have shown an increase in associated deaths over the past two decades. Chronic kidney disease affects approximately 50% of patients with type 2 diabetic mellitus (DM).

Objective

To determine CKD preventive attitude, practices, and associated factors among type 2 DM (T2DM) patients attending follow-up in a diabetic clinic at Asella Referral and Teaching Hospital.

Methods

Institutional based cross-sectional study was conducted at Asella Referral and Teaching Hospital among T2DM patients from December 23, 2021, to January 23, 2022. Data were entered into EpiData 4.2.00 and analyzed by Statistical Package for the Social Sciences version 23.0.

Result

A total of 216 study participants were included in to this study. The level of good preventive attitude and practice toward CKD among T2DM patients were 61.6% (n = 133, 95% CI: 55.6-68.0) and 54.6% (n = 118, 95% CI: 47.7-60.6), respectively. Age (50-59 years) (adjusted odds ratio [AOR] = 0.351, 95% CI: 0.125-0.988, p = .047), married (AOR = 4.423, 95% CI: 1.366-14.314, p = .013), urban residents (AOR = 0.321, 95% CI: 0.152-0.680, p = .003), and governmental employed (AOR = 0.269, 95% CI: 0.076-0.954, p = .042) were significantly associated with CKD preventive attitude. Formal education (AOR = 1.686, 95% CI: 1.416-5.502, p = .043), an average monthly income of ≥8000 ETB (AOR = 4.048, 95% CI: 1.129-14.520, p = .032), family history of CKD (AOR = 1.417, 95% CI: 1.231-7.136, p = .045) were significantly associated with CKD preventive practice.

Conclusion

The level of good preventive attitude and practice toward CKD among T2DM patients was 61.6% and 54.6%, respectively. Age, marital status, residence, and occupation were significantly associated with good preventive attitude of T2DM patients. Whereas educational status, average monthly income, and duration since diagnosed with T2DM were significantly associated with good CKD preventive practice. Health educational program needs to occur to improve the preventive attitude and practice toward CKD among T2DM patients.

The comorbidity burden of type 2 diabetes mellitus (T2DM): sex differences and associated factors among 830 cases in North-Eastern Morocco

Background and aim

Type 2 diabetes is prone to numerous comorbidities resulting from complex mechanisms involving hyperglycemia, insulin resistance, low-grade inflammation and accelerated atherogenesis. The purpose of the present study was to investigate these disorders and their associated risk factors according to patient sex in a population of type 2 diabetics in North-Eastern Morocco.

Methods

This study was conducted in a medical analysis laboratory over a 1-year period from 01/10/2018 to 01/10/2019. This epidemiological study was carried out on 830 subjects aged 18 and over. Quantitative variables were expressed as means ± standard deviation, and qualitative variables as frequencies and percentages. Hypothesis tests used to compare means and proportions were Student's t-test and Chi-square test of independence, respectively. Logistic regression was used to predict risk factors for each diabetes.

Results

830 patients were surveyed. 95.66% had diabetes-related comorbidities. Hypertension (23.7%), nephropathy (18.19%), dyslipidemia (14.82%), thyroid dysfunction (10.72%), cataract (10.12%), diabetic foot (7.23%), ketoacidosis (6.27%), retinopathy (3.49%), and skin disorders (2.77%) were observed. Sex was associated with dyslipidemia (p = 0.025), hypertension (p = 0.032) and retinopathy (p = 0.029). Uncontrolled blood sugar, unbalanced lipid profile, age, physical activity, obesity, smoking, and alcohol consumption were risk factors with differential involvement in the occurrence of the mentioned pathologies.

Conclusions

The results of our study showed that a significant proportion of the population suffers from diabetic comorbidities. To meet this challenge, further research is needed to identify the mechanisms of action of these factors, to control them and combat diabetogenic environments by setting up adapted educational programs.

The effect of brief educational intervention on level of awareness about chronic kidney disease among type-2 diabetes mellitus patients in Prince Sultan Military Hospital, Taif

Purpose

Lack of awareness about chronic kidney disease is prevalent and disrupts glycaemic control. In Saudi Arabia many authors highlighted the problem and called for educational interventions to be designed. Our study is the first to address this issue in Saudi Arabia and evaluate a brief educator-led educational intervention in terms of boosting awareness about and knowledge of chronic kidney disease among type two diabetes patients.

Method

This was an educational interventional investigation of patients with type two attending diabetes clinic in Taif, Saudi Arabia. The effect of a brief educational intervention focused on awareness about chronic kidney disease was assessed using chronic kidney disease knowledge scale before and after the intervention.

Results

We included (n = 100) type two diabetes patients. We estimated good reliability and internal consistency for the knowledge score (Cronbach's alpha was 0.79). Following the educational session, awareness about chronic kidney disease rose from 77 to 100% and knowledge score increased form 7.6 points at baseline to a 15.2 points; paired t value = 15.984, p < 0.00001). Improvement in awareness of chronic kidney disease was associated with being in employment, female sex, and shorter diabetes duration.

Conclusion

Brief educational intervention among patients with type two diabetes in Saudi Arabia leads to substantial improvement in awareness of and knowledge about chronic kidney disease. All items related to knowledge about chronic kidney disease improved substantially following educational intervention. It is recommended that all patients attending diabetes clinics receive focused education about chronic kidney disease.

Role of Synbiotics (Prebiotics and Probiotics) as Dietary Supplements in Type 2 Diabetes Mellitus Induced Health Complications

Diabetes is a metabolic disorder whose prevalence has become a worrying condition in recent decades. Chronic diabetes can result in serious health conditions such as impaired kidney function, stroke, blindness, and myocardial infarction. Despite a variety of currently available treatments, cases of diabetes and its complications are on the rise. This review article provides a comprehensive account of the ameliorative effect of prebiotics and probiotics individually or in combination i.e. synbiotics on health complications induced by Type 2 Diabetes Mellitus (T2DM). Recent advances in the field underscore encouraging outcomes suggesting the consumption of synbiotics leads to favorable changes in the gut microbiota. These changes result in the production of bioactive metabolites such as short-chain fatty acids (crucial for lowering blood sugar levels), reducing inflammation, preventing insulin resistance, and encouraging the release of glucagon-like peptide-1 in the host. Notably, novel strategies supplementing synbiotics to support gut microbiota are gaining attraction as pivotal interventions in mitigating T2DM-induced health complications. Thus, by nurturing a symbiotic relationship between prebiotics and probiotics i.e. synbiotics, these interventions hold promise in reshaping the microbial landscape of the gut thereby offering a multifaceted approach to managing T2DM and its associated morbidities. Supporting the potential of synbiotics underscores a paradigm shift toward holistic and targeted interventions in diabetes management, offering prospects for improved outcomes and enhanced quality of life for affected individuals. Nevertheless, more research needs to be done to better understand the single and multispecies pre/pro and synbiotics in the prevention and management of T2DM-induced health complications.

Advanced glycation end products and insulin resistance in diabetic nephropathy

Insulin resistance is a central hallmark that connects the metabolic syndrome and diabetes to the resultant formation of advanced glycation end products (AGEs), which further results in the complications of diabetes, including diabetic nephropathy. Several factors play an important role as an inducer to diabetic nephropathy, and AGEs elicit their harmful effects via interacting with the receptor for AGEs Receptor for AGEs, by induction of pro-inflammatory cytokines, oxidative stress, endoplasmic reticulum stress and fibrosis in the kidney tissues leading to the loss of renal function. Insulin resistance results in the activation of other alternate pathways governed by insulin, which results in the hypertrophy of the renal cells and tissue remodeling. Apart from the glucose uptake and disposal, insulin dependent PI3K and Akt also upregulate the expression of endothelial nitric oxide synthase, that results in increasing the bioavailability of nitric oxide in the vascular endothelium, which further results in tissue fibrosis. Considering the global prevalence of diabetic nephropathy, and the impact of protein glycation, various inhibitors and treatment avenues are being developed, to prevent the progression of diabetic complications. In this chapter, we discuss the role of glycation in insulin resistance and further its impact on the kidney.

The therapeutic effect of mesenchymal stem cells in diabetic kidney disease

Abstract

Diabetes mellitus (DM) often causes chronic kidney damage despite best medical practices. Diabetic kidney disease (DKD) arises from a complex interaction of factors within the kidney and the whole body. Targeting specific disease-causing agents using drugs has not been effective in treating DKD. However, stem cell therapies offer a promising alternative by addressing multiple disease pathways and promoting kidney regeneration. Mesenchymal stem cells (MSCs) offer great promise due to their superior accessibility ratio from adult tissues and remarkable modes of action, such as the production of paracrine anti-inflammatory and cytoprotective substances. This review critically evaluates the development of MSC treatment for DKD as it moves closer to clinical application. Results from animal models suggest that systemic MSC infusion may positively impact DKD progression. However, few registered and completed clinical trials exist, and whether the treatments are effective in humans is still being determined. Significant knowledge gaps and research opportunities exist, including establishing the ideal source, dose, and timing of MSC delivery, better understanding of in vivo mechanisms, and developing quantitative indicators to obtain a more significant therapeutic response. This paper reviews recent literature on using MSCs in preclinical and clinical trials in DKD. Potent biomarkers related to DKD are also highlighted, which may help better understand MSCs’ action in this disease progression.

R, S Mayya S, Prasad Nagaraju S, S Nayak B. Effectiveness of a Disease Management Program (DMP) in controlling the progression of Chronic Kidney Disease among hypertensives and diabetics

BACKGROUND

The occurrence rate of stage 5 chronic kidney disease (CKD) will be 151 per million population in India in the coming years. Comorbidities like diabetes mellitus and hypertension are the usual triggers of CKD. Hence this study aimed to control the progression of CKD and to note the effectiveness of a structured education program that would help in the prevention of complications related to diabetes and hypertension.

METHODS

This quasi-experimental study was conducted among 88 participants who had hypertension, diabetes mellitus, or both for five or more years. The study objective was to find the effect of a Disease Management Program on delaying progression of CKD in patients with hypertension or diabetes mellitus.The baseline data were obtained from demographic proforma, and the clinical data collected were the blood pressure, serum creatinine, and random blood sugar (RBS) of the participants. The management of hypertension and diabetes mellitus was taught to them. In the fourth and the eighth month, blood pressure and blood sugar were reassessed. At one-year blood pressure, blood sugar, and serum creatinine were tested. Baseline and one-year follow-up blood pressure, blood sugar, and estimated Glomerular Filtration Rate were compared. Descriptive statistics and "Wilcoxon signed-rank test" were used to analyze the data.

RESULTS

In one year, the mean systolic blood pressure reduced by six mm of Hg and mean blood sugar by 24 mg/dl. The prevalence of CKD stage three and above (< 60 ml/min/m2) was nine (10.22%). The median decline in eGFR was 5 ml/min/m2 (Z= 5.925, P< 0.001).

CONCLUSION

The Disease Management Program led to improvements in blood pressure and diabetes control and median progression of CKD was estimated at five ml/min/m2/year.

Insights into the Therapeutic uses of Plant Derive Phytocompounds onDiabetic Nephropathy

Diabetic nephropathy (DN) is one of the primary consequences of diabetes mellitus, affecting many people worldwide and is the main cause of death under the age of sixty. Reactive oxygen species (ROS) production rises during hyperglycemia and is crucial to the development of diabetic complications. Advanced glycation end products (AGEs) are produced excessively in a diabetic state and are accumulated in the kidney, where they change renal architecture and impair renal function. Another important targeted pathway for the formation of DN includes nuclear factor kappa-B (NF-kB), Nuclear factor E2-related factor 2 (Nrf2), NLR family pyrin domain containing 3 (NLRP3), protein kinase B/mammalian target of rapamycin (Akt/mTOR), and autophagy. About 40% of individuals with diabetes eventually acquire diabetic kidney disease and end-stage renal disease that needs hemodialysis, peritoneal dialysis, or kidney transplantation to survive. The current state of acceptable therapy for this kidney ailment is limited. The studies revealed that some naturally occurring bioactive substances might shield the kidney by controlling oxidative stress, renal fibrosis, inflammation, and autophagy. In order to provide new potential therapeutic lead bioactive compounds for contemporary drug discovery and clinical management of DN, this review was designed to examine the various mechanistic pathways by which conventional plants derive phytocompounds that are effective for the control and treatment of DN.

Prediction of diabetic kidney disease risk using machine learning models: A population-based cohort study of Asian adults

Background

Machine learning (ML) techniques improve disease prediction by identifying the most relevant features in multidimensional data. We compared the accuracy of ML algorithms for predicting incident diabetic kidney disease (DKD).

Methods

We utilized longitudinal data from 1365 Chinese, Malay, and Indian participants aged 40-80 y with diabetes but free of DKD who participated in the baseline and 6-year follow-up visit of the Singapore Epidemiology of Eye Diseases Study (2004-2017). Incident DKD (11.9%) was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 with at least 25% decrease in eGFR at follow-up from baseline. A total of 339 features, including participant characteristics, retinal imaging, and genetic and blood metabolites, were used as predictors. Performances of several ML models were compared to each other and to logistic regression (LR) model based on established features of DKD (age, sex, ethnicity, duration of diabetes, systolic blood pressure, HbA1c, and body mass index) using area under the receiver operating characteristic curve (AUC).

Results

ML model Elastic Net (EN) had the best AUC (95% CI) of 0.851 (0.847-0.856), which was 7.0% relatively higher than by LR 0.795 (0.790-0.801). Sensitivity and specificity of EN were 88.2 and 65.9% vs. 73.0 and 72.8% by LR. The top 15 predictors included age, ethnicity, antidiabetic medication, hypertension, diabetic retinopathy, systolic blood pressure, HbA1c, eGFR, and metabolites related to lipids, lipoproteins, fatty acids, and ketone bodies.

Conclusions

Our results showed that ML, together with feature selection, improves prediction accuracy of DKD risk in an asymptomatic stable population and identifies novel risk factors, including metabolites.

Glycemic index of a nutritional supplement designed for people with chronic kidney disease

The study was carried out to measure the glycemic index (GI) of an oral food supplement for people with CKD as well as on patients on maintenance dialysis. The study was conducted as per international protocols for testing GI, was approved by the local institutional ethics committee, and was registered with the Clinical Trial Registry of India (CTRI). This was a crossover randomized controlled study which enrolled 15 participants between the ages of 18 and 45 years. The participants were randomly allotted to one group that consumed either the reference food (27.5 g of glucose monohydrate) or 118 g of the nutritional supplement which contained 25 g of available carbohydrates. Fasting capillary blood samples as well as blood samples at different time intervals as per the GI protocol, after consumption of either the supplement or the reference food were taken from the participants. Each testing day was separated by a 3-day washout period. GI was calculated from the incremental area under the blood glucose response elicited by the nutritional supplement as a percentage of the response after the consumption of 25 g of glucose (27.5 g of glucose monohydrate) by the same participant using a standard formula. The GI of the nutritional supplement was calculated to be 10.3 ± 2.0 which is considered to be low as per international GI testing standards. The product was created to supplement the diet of people with CKD at different stages and to help prevent the progression from CKD to ESRD as well as the risk for CVD. This product was found to have a low GI which is desirable for people with CKD as well as diabetics in general who are at risk for developing CKD.

The roles of gut microbiota and its metabolites in diabetic nephropathy

Diabetic nephropathy (DN) is a severe microvascular complication of diabetes, which increases the risk of renal failure and causes a high global disease burden. Due to the lack of sustainable treatment, DN has become the primary cause of end-stage renal disease worldwide. Gut microbiota and its metabolites exert critical regulatory functions in maintaining host health and are associated with many pathogenesis of aging-related chronic diseases. Currently, the theory gut-kidney axis has opened a novel angle to understand the relationship between gut microbiota and multiple kidney diseases. In recent years, accumulating evidence has revealed that the gut microbiota and their metabolites play an essential role in the pathophysiologic processes of DN through the gut-kidney axis. In this review, we summarize the current investigations of gut microbiota and microbial metabolites involvement in the progression of DN, and further discuss the potential gut microbiota-targeted therapeutic approaches for DN.

Patient and health care provider knowledge of diabetes and diabetic microvascular complications: a comprehensive literature review

Diabetic retinopathy, neuropathy, and nephropathy occur in more than 50% of people with diabetes, contributing substantially to morbidity and mortality. Patient understanding of these microvascular complications is essential to ensure early recognition and treatment of these sequalae as well as associated symptoms, yet little is known about patient knowledge of microvascular sequalae. In this comprehensive literature review, we provide an overview of existing knowledge regarding patient knowledge of diabetes, retinopathy, neuropathy, and nephropathy. We also discuss health care provider's knowledge of these sequalae given that patients and providers must work together to achieve optimal care. We evaluated 281 articles on patient and provider knowledge of diabetic retinopathy, neuropathy, and nephropathy as well as predictors of improved knowledge and screening practices. Results demonstrated that patient and provider knowledge of microvascular sequalae varied widely between studies, which may reflect sociocultural or methodologic differences. Knowledge assessment instruments varied between studies with limited validation data and few studies controlled for confounding. Generally, improved patient knowledge was associated with greater formal education, longer diabetes duration, and higher socioeconomic status. Fewer studies examined provider knowledge of sequalae, yet these studies identified multiple misconceptions regarding appropriate screening practices for microvascular complications and the need to screen patients who are asymptomatic. Further investigations are needed that use well validated measures, control for confounding, and include diverse populations. Such studies will allow identification of patients and providers who would benefit from interventions to improve knowledge of microvascular complications and, ultimately, improve patient outcomes.

Association of Atherogenic Index of Plasma With Retinopathy and Nephropathy in Adult Patients With Type 2 Diabetes Mellitus Aged >18 Years

OBJECTIVES

In this study, we assessed the atherogenic index of plasma (AIP) in relation to retinopathy and nephropathy in patients with type 2 diabetes mellitus (T2DM).

METHODS

In this cross-sectional study, there were 4,358 inpatients with T2DM. The patients were divided into 4 groups: T2DM without complications (DM group), T2DM complicated with retinopathy alone and nephropathy alone (DR-alone and DN-alone groups) and T2DM complicated with both DR and DN (DRN group). AIP was calculated by the formula of log (triglyceride/high-density lipoprotein cholesterol).

RESULTS

AIPs in the DR-alone, DN-alone and DRN groups were significantly higher than those in the DM group, with the DRN group having the highest AIP level. Moreover, patients with proliferative DR had higher AIPs than patients with nonproliferative DR in the DR-alone and DRN groups, and patients with macroalbuminuria had higher AIPs than patients with microalbuminuria in DN-alone and DRN groups. The highest AIP quartile group had the highest proportion of DRN compared with the other quartile groups. The DRN group had a maximal area under the curve (AUC) for AIP on receiver operating characteristic curve analysis (AUC=0.735). In the subgroup analyses by age, the AUCs of patients <65 years of age were all greater than those of patients ≥65 years of age. Logistic regression analysis showed that AIP had the highest correlation with age <65 years in individuals with DRN, and this association remained significant after adjustment with 3 models.

CONCLUSIONS

AIP is positively associated with both occurrence and severity of diabetic microvascular complications. It can predict their presence in T2DM, especially in those <65 years of age with DRN.

Knowledge of chronic kidney disease among undergraduate and postgraduate students in a public university in Klang Valley, Malaysia: A cross sectional study

The prevalence of chronic kidney disease (CKD) risk factors such as diabetes mellitus, hypertension, and obesity among the young Malaysians are increasing. Understanding the factors associated with CKD knowledge could assists healthcare providers to design health education programmes. There are scarce local studies on CKD knowledge and its associated factors among university students. This subpopulation comprises of young people with diverse background and characteristics. This study was aimed to assess the CKD knowledge and its associated factors among university students. A cross-sectional study was conducted among Universiti Kebangsaan Malaysia students from July 2020 to August 2020. A convenience sampling method was applied. All students were invited to complete an online survey using Google Forms that were sent to their email. The survey consisted of questions related to their sociodemographic, socioeconomics, university programme enrolled, medical history, lifestyle characteristics and CKD knowledge. The data were analysed using SPSS Statistics 26.0. Multiple logistic regression analysis was performed to identify the final associated factors after controlling for confounders. A total of 3074 students participated and 32.6% of them had below average CKD knowledge. Students of male gender, enrolment in undergraduate programmes and non-health-related faculties/institutes were more likely to have below average CKD knowledge. Students who are Chinese, from high monthly household income family and with family history of CKD were less likely to have below average CKD knowledge. Almost one-third of the students had below average CKD knowledge. The six associated factors with CKD knowledge were non-modifiable. Of the six factors, three were associated with students being more likely to have below average CKD knowledge; another three were associated with students being less likely to have below average CKD knowledge. Future health education programmes to enhance CKD knowledge should be designed focusing on students who are more likely to have below average CKD knowledge.

Comparative efficacy of novel antidiabetic drugs on cardiovascular and renal outcomes in patients with diabetic kidney disease: A systematic review and network meta-analysis

AIMS

To conduct a systematic review and network meta-analysis to determine the comparative effectiveness of sodium-glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1RAs) and dipeptidyl peptidase-4 (DPP-4) inhibitors in patients with diabetic kidney disease (DKD).

METHODS

Phase III or IV randomized, placebo-controlled trials evaluating SGLT2 inhibitors, GLP-1RAs or DPP-4 inhibitors in patients with DKD were identified from the MEDLINE database. The outcomes of interest were a kidney-specific composite outcome, kidney disease progression, major adverse cardiovascular events (MACE), hospitalization for heart failure (HHF) and cardiovascular death. A network meta-analysis was conducted to calculate hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Sixteen trials representing a total of 46 292 patients were included. SGLT2 inhibitors significantly reduced the risk of the kidney-specific composite outcome by 26% compared to GLP-1RAs (HR 0.74, 95% CI 0.62-0.88) and by 36% compared to DPP-4 inhibitors (HR 0.64, 95% CI 0.52-0.79). The risk of MACE was significantly reduced with SGLT2 inhibitors (by 18%; HR 0.82, 95% CI 0.72-0.93), and with GLP-1RAs (by 18%; HR 0.82, 95% CI 0.69-0.96), compared to DPP-4 inhibitors. SGLT2 inhibitors significantly reduced the risk of HHF by 28% compared to GLP-1RAs (HR 0.72, 95% CI 0.56-0.92) and by 41% compared to DPP-4 inhibitors (HR 0.59, 95% CI 0.49-0.71).

CONCLUSIONS

A clear advantage was demonstrated by SGLT2 inhibitors in reducing the risks of CV and renal events in patients with DKD, compared to GLP-1RAs and DPP-4 inhibitors. We recommend that SGLT2 inhibitors be considered the treatment of choice in patients with DKD.

Chronic kidney disease awareness among the general population: tool validation and knowledge assessment in a developing country

Introduction

Good knowledge and early identification of chronic kidney disease (CKD) can help in preventing disease progression in its early stages and reducing undesired outcomes. The aim of the current study was to assess the level of public knowledge about CKD, determine predictors of better knowledge, and to construct and validate a CKD knowledge scale for public health assessment and research use.

Methods

A community-based cross-sectional study was conducted using an electronic self-administered questionnaire. All people living in Lebanon and being 18 years of age and above were considered eligible for recruitment. CKD knowledge was assessed by a 37-item scale that was constructed by principal component analysis and then validated. The score of the CKD knowledge scale was computed from the extracted factors. A multivariable binomial logistic regression model evaluated the sociodemographic and clinical predictors of the knowledge score.

Results

A total of 1308 participants were included. The scale items converged over 9 factors with Eigenvalue greater than 1 and explaining 53.26% of the total variance, and the total scale had a high Cronbach’s alpha of 0.804. All items of the scale significantly correlated with the full scale with correlation coefficients ranging from 0.082 to 0.558. The ROC curve analysis determined an optimal cutoff point of better knowledge at 47.5 with 70.6% sensitivity and 44.2% specificity. The CKD knowledge score had a median of 51.00 (IQR 47.00–55.00). Higher knowledge score was significantly associated with old age (ORa = 1.018, 95% CI 1.006–1.030, P = 0.003),, occupation (ORa = 3.919, 95% CI 2.107–7.288, P <  0.001), and recent renal function assessment (ORa = 2.314, 95% CI 1.532–3.495, P <  0.001). However, a lower knowledge score was significantly associated with lower level of education (ORa = 0.462, 95% CI 0.327–0.653, P <  0.001).

Conclusion

A reliable tool to assess public knowledge and awareness about CKD was developed and validated. The overall knowledge was good, however, important gaps in CKD awareness were detected in some areas and subpopulations. Therefore, public health stakeholders need to implement targeted CKD educational activities to minimize the disease burden.

A Glimpse of Inflammation and Anti-Inflammation Therapy in Diabetic Kidney Disease

Diabetic kidney disease (DKD) is a common complication of diabetes mellitus and a major cause of end-stage kidney disease (ESKD). The pathogenesis of DKD is very complex and not completely understood. Recently, accumulated evidence from in vitro and in vivo studies has demonstrated that inflammation plays an important role in the pathogenesis and the development of DKD. It has been well known that a variety of pro-inflammatory cytokines and related signaling pathways are involved in the procession of DKD. Additionally, some anti-hyperglycemic agents and mineralocorticoid receptor antagonists (MRAs) that are effective in alleviating the progression of DKD have anti-inflammatory properties, which might have beneficial effects on delaying the progression of DKD. However, there is currently a lack of systematic overviews. In this review, we focus on the novel pro-inflammatory signaling pathways in the development of DKD, including the nuclear factor kappa B (NF-κB) signaling pathway, toll-like receptors (TLRs) and myeloid differentiation primary response 88 (TLRs/MyD88) signaling pathway, adenosine 5′-monophosphate-activated protein kinase (AMPK) signaling pathways, inflammasome activation, mitochondrial DNA (mtDNA) release as well as hypoxia-inducible factor-1(HIF-1) signaling pathway. We also discuss the related anti-inflammation mechanisms of metformin, finerenone, sodium-dependent glucose transporters 2 (SGLT2) inhibitors, Dipeptidyl peptidase-4 (DPP-4) inhibitors, Glucagon-like peptide-1 (GLP-1) receptor agonist and traditional Chinese medicines (TCM).

Awareness of Chronic Kidney Disease, Medication, and Laboratory Investigation among Nephrology and Urology Patients of Quetta, Pakistan

Patients’ awareness is critical in medical care, as it can serve as an input into the adjustment of interventions. The aim of study was to explore the level of awareness regarding chronic kidney disease (CKD), its medications, and laboratory investigations among nephrology and urology patients of Quetta. The cross-sectional study was used by adopting and culturally modifying a questionnaire. By convenient sampling technique, a total of 500 questionnaires were self-administered to inpatients, outpatients, and dialysis patients, and 468 responses (response rate 93.6%) were analyzed. Descriptive statistics, inferential statistics, and reliability analysis were performed on SPSS v25. A majority, 50.3% (n = 235), was unaware of symptoms that will develop due to worsening of disease, while 56.2% (n = 263) were unaware of what aggravates their kidney function. Almost half of the affected individuals, 47.4% (n = 222), have no understanding about the long-term prognosis of the disease. The majority of the respondents, 51.5% (n = 248), do not know about the names and usage of medications, and 62.4% (n = 292) were unaware of the medicines that may impair kidney function; more than half, 66.7% (n = 312), were unaware about the necessary laboratory investigations. A strong association between awareness and patient education level was found (p < 0.001). Awareness regarding disease condition, medications, and laboratory investigations of CKD among nephrology and urology patients of Quetta was found out to be low, which needs immediate educational intervention.

A systematic review on nephron protective AYUSH drugs as constituents of NEERI-KFT (A traditional Indian polyherbal formulation) for the management of chronic kidney disease

Chronic Kidney Disease (CKD) is a major health problem characterized by kidney dysfunction with progressive segmental glomerulosclerosis to end-stage renal disease (ESRD). Due to lack of scientific data and comprehensive reports, the current systematic review provides an inclusive understanding and prospective associated with phytopharmacology of NEERI-KFT in CKD. The data was collected from more than five databases such as Science Direct, Google Scholar, Elsevier, PubMed, Springer, ACS publication etc using keywords like CKD/Kidney disease, epidemiology/prevalence, modern therapies for CKD management, NEERI-KFT and its role in kidney disease. The study was performed based on scientific reports screened by experts according to inclusion and exclusion criteria. The pre-clinical and clinical findings suggested that NEERI-KFT has promising effects as nephroprotective and considered safe and well effective in primary care of kidney against disease. Phytopharmacological evaluation of NEERI-KFT suggest that it exhibit substantial potential against oxidative and inflammatory stress induced apoptosis by exerting antioxidants, nephroprotective and immunomodulatory effects. Hence, it can be enlighten that NEERI-KFT have potential herbs which exerts significant antioxidants, nephroprotective and immunomodulatory effects in the patients associated with renal dysfunction or CKD thus improving altered renal architecture and renal physiology. Clinically, it is concluded that NEERI-KFT works kidney malfunction and cease ESRD progression or even reduce the number of dialysis.

Prevalence of Chronic Kidney Diseases in Patients with Diabetes Mellitus in the Middle East: A Systematic Review and Meta-Analysis

AIMS

The prevalence of CKD in patients with diabetes mellitus in the Middle East region is unknown. Therefore, we aimed to understand the pooled prevalence of CKD in patients with diabetes mellitus in the Middle East region.

METHODS

PubMed, Embase, and Cochrane databases were searched for relevant studies up to October 2020. The search strategy was conducted using both keywords and MeSH terms. Randomised controlled trials (RCTs) and observational studies that included patients from all age groups and any study design that reported on the prevalence of CKD in patients with diabetes mellitus were included. The pooled estimate for the prevalence of CKD in patients with diabetes was calculated using random-effect models with 95% confidence intervals (CIs).

RESULTS

A total of 489 citations were identified, of which only nine studies matched our inclusion criteria and were included in the meta-analysis. All of the studies used an observational study design covering a total of 59,395 patients with type 2 diabetes mellitus. The pooled estimate of the prevalence of CKD in patients with diabetes mellitus was 28.96% (95% CI: 19.80-38.11).

CONCLUSIONS

A high prevalence of CKD in patients with diabetes mellitus in the Middle East region was found. Further epidemiological studies are warranted in this area to have a better estimate of the prevalence of CKD among DM in the Middle East region.

Prevalence of peripheral neuropathy and associated pain in patients with diabetes mellitus: Evidence from a cross-sectional study

Background

Diabetic peripheral neuropathy (DPN) is the most common and troublesome complication of diabetes mellitus. It affects almost half the population with diabetes and worsens quality of life of the patient. This study was aimed to determine the prevalence of peripheral neuropathy and associated pain in patients with diabetes mellitus.

Methods

This was a cross-sectional study conducted over a period of six months. Patient's ≥ 18 years with confirmed diagnosis of diabetes mellitus were included in the study. Patients with hypothyroidism, medical illness such as cancer, liver or renal disease, cervical or lumbar spondylosis, pregnant patients with diabetes and patients receiving any treatment that might influence nerve function (e.g., cytotoxic or antiepileptic agents) were excluded from the study. DPN was diagnosed using 10 g monofilament test. The S-LANSS questionnaire was used to assess the associated painful symptoms. Association was calculated using chi-square test. A p- value of ≤0.05 was considered statistically significant. All the statistical analysis was performed using SPSS v22.

Result

The overall prevalence of DPN was found to be 28.85% from which 88% patients were found to have painful symptoms. A significant association of DPN was observed with the duration of diabetes (p = 0.004), poor glycaemic control (p = 0.03) and other diabetic complications such as nephropathy (p = 0.002). No association of neuropathy was found with retinopathy and hypertension. Duration of diabetes (>15 years), and HbA1c (>9%) was found to be positively associated the painful DPN.

Conclusion

The current study found a high prevalence of DPN and it was found to be significantly associated with duration of diabetes, poor glycaemic control and nephropathy.

Early detection of renal disease among truck drivers through organized screening

BACKGROUND

Trucking industry is the backbone of trade and economy and in India, truck drivers are occupationally faced with various challenges. Several risk factors including stress and abnormal lifestyle predisposes this group to non-communicable disease and chronic kidney disease (CKD) is one of the major threats. This study was carried out to evaluate the prevalence and risk factors of chronic kidney disease.

METHODS

The present cross-sectional study was carried out as a population-based screening programme among 3,200 truck drivers in Tamil Nadu for a period of 1 year in 2018. A structured proforma was used to obtain information regarding the diabetic and hypertensive status. Body mass index was calculated and blood pressure was measured using standard equipments. Urine dipstick method was used to detect the presence of albumin and glucose in the urine.

RESULTS

The mean age of the participants was 40.3 years. Overweight and obesity was seen in 49.9% of the participants, while elevated blood pressure was observed in 41.1%. About 12.4% of the participants were known hypertensives on medications. Albuminuria was present in 19.7% of the participants. Albuminuria was significantly associated with elevated blood pressure, high body mass index and elevated random blood sugars (P < 0.0001). In 83.7% of the participants, random blood sugar was elevated beyond 200 mg/dl.

CONCLUSION

The screening programme can be enhanced when coupled with an awareness campaign, with due focus on culturally relevant information delivered by trained health educators in the native language, so as to bring about adequate education through effective communication.

Anemia prevalence and its impact on health-related quality of life in Indian diabetic kidney disease patients: Evidence from a cross-sectional study

AIM

The aim of the study was to determine the prevalence, predictors of anemia, and its impact on health-related quality of life among diabetic kidney disease (DKD) patients.

METHODS

Patients with a confirmed diagnosis of type 2 diabetes mellitus (T2DM), and had any stages of CKD (stages I to IV), based on their estimated glomerular filtration rate (eGFR) were enrolled in the study. Anemia was defined using the World Health Organization (WHO) criteria and quality of life was assessed using the EQ-5D scale. All the statistical analysis was performed using SAS v9.4.

RESULTS

A total of 323 patients completed the study. The mean ± SD age of patients was 56 ± 11.25 years, and 51.7% were female. Mean duration of diabetes was 9.6 ± 4.57 years. A total of 227 (70.27%) had anemia as per the WHO criteria. Linear association was observed between the eGFR and hemoglobin. After controlling for the possible confounders in multivariate logistic regression analysis, older age (odds ratio [OR]: 2.46 [95% CI: 1.16 to 5.28], P = .021), diabetes duration (OR: 1.53 [95% CI: 1.04 to 2.25], P = .022), and CKD stage III (OR: 3.63 [95% CI: 0.99 to 13.32], P = .004) were found to be significantly associated with the anemia. Consistently lower EQ-5D index values were observed for the anemic group.

CONCLUSION

This study reported a high prevalence of anemia and impaired quality of life among DKD patients. Routine screening of anemia can be the most preventive measure to deal with this burdening co-morbid condition.
