Prevalence and risk factors of chronic kidney disease among patients with type 2 diabetes mellitus at a tertiary care hospital in Nepal: a cross-sectional study

Chronic kidney disease risk assessment: Findings from backward-looking study using annual health check-up data in Japan

AIMS/INTRODUCTION

While studies on kidney disease (KD) in patients with severe metabolic syndrome (MetS) have been reported, research on undiagnosed MetS individuals is limited. This study aimed to investigate KD mechanisms in early MetS stages among Japanese individuals to establish accurate KD prediction models applicable to specific health guidance using annual health check-up (HC) data.

MATERIALS AND METHODS

Cox regression analysis was conducted using the Kokuho Database including HC and claims data over the past 10 years. Survival time was defined as the period from the initial HC during the observation period until estimated glomerular filtration rate (eGFR) fell below the following cut-offs: 60 mL/min/1.73 m2 chronic kindney disease (CKD) and 15 mL/min/1.73 m2 (ESKD) for primary scenarios, 45 mL/min/1.73 m2 (CKD Stage 3b) and 30 mL/min/1.73 m2 (CKD Stage 4) for additional scenarios. Predictive factors included age, sex and serum creatinine, which are components of eGFR, and MetS factors as follows: body mass index (BMI), glycated haemoglobin A1c (HbA1c), triglycerides (TG) and systolic blood pressure (SBP).

RESULTS

Significant increases in hazard ratios (HRs) for BMI, HbA1c, TG and SBP were observed for primary and additional cut-offs. BMI, HbA1c and TG showed progressively stronger HR increases with advancing stages. The model for all scenarios demonstrated goodness of fit with the high C-statistics.

CONCLUSIONS

This study highlights the necessity of a comprehensive evaluation of MetS factors in CKD risk assessment and shows the model using annual HC data can identify CKD progression effectively and accurately. A risk assessment approach considering multiple CKD stages will be crucial for early intervention and disease prevention strategies.

Chronic Kidney Disease-Epidemiology Collaboration (CKD - EPI) classification of kidney function and predictors of kidney dysfunction among type 2 diabetes mellitus patients in a tertiary hospital in Ghana

Introduction

Type 2 Diabetes Mellitus (T2DM) is a major global health concern frequently associated with Kidney Dysfunction (KD). Globally, approximately one in eleven adults have diabetes mellitus, with 90% of these cases being type 2 diabetes mellitus. About two-thirds of T2DM patients experience KD, which may progress to chronic kidney disease and end-stage renal disease. In Ghana, the burden of T2DM is substantial and continues to rise, with kidney failure accounting for approximately 10% of all deaths among individuals with T2DM. This study sought to investigate the predictors of KD among T2DM patients in Ghana and approximately 10% of deaths in people with T2DM are attributable to kidney failure.

Methods

a hospital-based retrospective study design was employed. It involved the medical records of 141 T2DM patients. The data extracted was entered into Microsoft Excel version 16.0 and analyzed using STATA version 16.0. Chi-square test was used to establish associations between categorical variables and KD. Independent t-test was employed to analyze associations between parametric (normally distributed) variables and KD, while the Mann-Whitney U test was used for non-parametric (not normally distributed) variables. The strengths of the identified associations were evaluated using binary logistic regression analysis, with the results reported as odds ratios (OR) along with their 95% confidence intervals.

Results

among the 141 patients, 99 (70.2%) had KD. Formal employment was associated with a 95% reduced odds of kidney dysfunction (aOR = 0.05 (95%CI: 0.004-0.645); p-value = 0.021), while every unit increase in creatinine level was linked to a 10% increased odds of KD (aOR = 1.10 (95%CI: 1.06-1.14); p-value = <0.001).

Conclusion

the study revealed a significant proportion of T2DM patients experiencing kidney dysfunction. Crucially, both occupation and creatinine levels were found to be independent predictors of diabetic KD. This highlights an urgent need to educate T2DM patients, particularly those who are unemployed or informally employed, about preventive measures and the importance of regular monitoring of creatinine levels to safeguard kidney health. This emphasis is vital, as managing kidney disease in the region is notably costly, making early intervention and education key strategies in reducing the burden of KD among T2DM patients.

Prevalence of chronic kidney disease and associated factors among adult diabetic patients: a hospital-based cross-sectional study

Background

Chronic kidney disease (CKD) has a significant impact on public health with a high morbidity and death rate. Most diabetic patients, in the course of their lives, develop diabetic kidney disease. In the least developed nations, its size is outstripping itself. This study aimed to determine the prevalence of chronic kidney disease and associated factors among adult diabetic patients.

Methods

A hospital-based cross-sectional study was conducted on 328 adult diabetic patients from 1 December 2023 to 4 April 2024 at the Ayder Comprehensive Specialized Hospital, northern Ethiopia. A systematic random sampling method was utilized to select the study participants. Pretested structured questionnaires were used to collect sociodemographic, economic, and behavioral/lifestyle factors. Medical records were also reviewed to collect clinical data. Creatinine analysis was performed by kinetic alkaline picrate method and Chronic Kidney Disease Epidemiology Collaboration 2021 equation was used to calculate the glomerular filtration rate from the serum creatinine, age, and sex. Proteinuria was determined by using the dipstick semiquantitative method. Data were entered and analyzed using SPSS version 29. A variable with a p-value of <0.25 in bivariate logistic regression analyses was analyzed in multivariate logistic regression to identify the associated factors. In multivariable logistic regression, a variable was deemed statistically significant if it had a p-value <0.05. Associations were presented as odds ratio (OR) along with 95% confidence intervals (CIs).

Results

The prevalence of chronic kidney diseases in adult diabetic patients was 26.5% (95% CI, 21.8%-31.7%). About 5.2%, 12.5%, 7.3%, 0.9%, and 0.6% had stage 1-5 chronic kidney diseases, respectively. Hypertension [adjusted OR (AOR) = 2.390; 95% CI, 1.394-4.099, p = 0.002], >10-year duration of diabetes (AOR = 2.585; 95% CI, 2.321-5.807; p = 0.001), and family history of kidney diseases (AOR = 2.884; 95% CI, 1.338-6.218; p = 0.007) were associated factors of chronic kidney diseases.

Conclusions

The study revealed that one in four diabetic patients had chronic kidney disease. Special attention should be given to patients with family history of CKD, long duration on diabetes, and concomitant hypertension.

Can Novel Biomarkers Effectively Predict Acute Kidney Injury in Liver or Kidney Transplant Recipients?

Acute kidney injury (AKI) constitutes a common complication associated with liver or kidney transplantation, which may significantly impact the graft condition and perioperative mortality. Current AKI diagnostic criteria based on serum creatinine (sCr) and urine output alterations are widely utilized in routine clinical practice. However, the diagnostic value of sCr may be limited by various confounding factors, including age, sex, reduced or increased muscle mass, and pre-existing chronic kidney disease (CKD). Furthermore, sCr is rather a late indicator of AKI, as its concentration tends to increase only when the severity of the injury is enough to decrease the estimated glomerular filtration rate (eGFR). Recent expertise highlights the need for novel biomarkers in post-transplantation AKI diagnosis, prediction of event-associated mortality, or evaluation of indications for renal replacement treatment (RRT). Over the last decade, the diagnostic performance of various AKI biomarkers has been assessed, among which some showed the potential to outperform sCr in AKI diagnosis. Identifying susceptible individuals, early diagnosis, and prompt intervention are crucial for successful transplantation, undisturbed graft function in long-term follow-up, and decreased mortality. However, the research on AKI biomarkers in transplantation still needs to be explored. The field lacks consistent results, rigorous study designs, and external validation. Considering the rapidly growing prevalence of CKD and cirrhosis that are associated with the transplantation at their end-stage, as well as the existing knowledge gap, the aim of this article was to provide the most up-to-date review of the studies on novel biomarkers in the diagnosis of post-transplantation AKI.

Nutritional Risk Factors in Albuminuria and Retinopathy in Patients Newly Diagnosed With Type 2 Diabetes: A Cross-sectional Case Series Study

BACKGROUND/AIM

Although nutritional risk factors for developing complications in type 2 diabetes mellitus (T2DM) have been examined, the effect of protein intake on nephropathy is debated, and there is little research on retinopathy. This cross-sectional case-series study aimed to examine the risk factors, including nutritional status, for complications in patients newly diagnosed with T2DM.

PATIENTS AND METHODS

Fifty-four patients were recruited, based on the results of examinations of blood glucose and/or glycated hemoglobin level for T2DM. To evaluate nutritional status, blood and urine examinations were performed and the Food Frequency Questionnaire was administered. Two-way analysis of variance, Fisher's exact test and logistic regression analyses were performed.

RESULTS

The patients were categorized into four groups: 24 without albuminuria and without retinopathy, four without albuminuria with retinopathy, 21 with albuminuria without retinopathy, and five with albuminuria with retinopathy. Logistic analysis of albuminuria revealed that estimated sodium intake was significantly independent as the explanatory factors of age, sex, and body mass index. Patients with retinopathy had significantly higher blood urea nitrogen, and significantly lower plasma total protein levels than patients without retinopathy, suggesting that retinopathy is related to a higher catabolic state. Through a questionnaire on food intake, patients with retinopathy had a significantly lower intake of fat and monounsaturated fatty acids and a significantly higher intake of iodine based on intake of seaweed, corrected for energy intake, than patients without retinopathy.

CONCLUSION

The present study may lead to planning a large cohort study for examining nutritional risk factors related to complications in patients newly diagnosed with T2DM in Japan.

Prevalence of chronic kidney disease in Tunisian diabetics: the TUN-CKDD survey

BACKGROUND

In Tunisia, the prevalence of diabetes mellitus increased from 15.5% on 2016 to 23% by 2023. While Chronic Kidney Disease (CKD) stills the most dreaded complications of diabetes, studies on the prevalence of chronic kidney disease non-dialysis diet are scarce. The aim of this study was to assess the prevalence of chronic kidney disease among the Tunisian diabetic population based on investigators' specialty, demographic criteria (gender, age, duration of diabetes and geographic distribution) and diagnosis criteria (albuminuria and/or eGFR).

METHODS

This observational, multicentric, and cross-sectional study enrolled all diabetic subjects from all regions of Tunisia with at least 3 months of follow-up before the inclusion date, from 09 January to 08 February 2023. CKD diagnosis was established based on the KDIGO guidelines. The study was carried out at medical departments and ambulatory clinics of different healthcare providers. Baseline data were collected by investigators using an electronic case report form (eCRF). Continuous variables were described by means, median, standard deviation, and quartiles. Categorical data were tabulated in frequencies and percentages.

RESULTS

The overall prevalence of CKD among the 10,145 enrolled patients with diabetes mellitus was 38.7% with a 95%CI [37.8-39.6%]. 50.9% were male, with a mean age of 67.5 (± 11.3) years. The mean diabetes duration was 16.1 years (± 8.9). The highest CKD prevalence was noted among nephrologists (82.2%), while it was similar between the cardiologists and the primary care physicians (30.0%). CKD prevalence was highest among males (43.0% versus 35.1%) and increased proportionally with patients' age and diabetes duration. CKD was more frequent in the Mid-East Area when compared to other regions (49.9% versus 25.3 to 40.1% in other regions). Albuminuria was present within 6.6% of subjects with CKD, and it was found an estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m² within 13.3% of subjects wit h CKD. 18.9% had both criteria.

CONCLUSIONS

In Tunisia, CKD among diabetics had a prevalence of 38.7%, approaching European prevalence. The prevalence discrepancy worldwide of CKD can be improved with a larger population size and by implementing standardized practices.

[Exploring facilitators and barriers to implementing expanded nursing roles in MexicoEstudo de facilitadores e barreiras para a implementação de funções ampliadas de enfermagem no México]

Objective

To explore the perceptions of nursing professionals regarding facilitators and barriers to the implementation of expanded nursing functions in a state in central Mexico.

Methods

Qualitative descriptive phenomenological study. During 2022, 18 semi-structured interviews were conducted with three types of informants: a) head nurses at state-level facilities; b) head nurses at local-level facilities; and c) heads of health units and operational nursing staff who have direct contact with patients.

Results

The following facilitators were identified: willingness to adopt the strategy (seen as favorable by managers and acceptable by nursing staff); reorganization of functions (simplification of processes and analysis of the situation of health units); access to training; and characteristics of nursing staff (professionalization, work experience, and favorable attitude). Barriers included: conditions at the first level of care (personnel shortages, too many administrative activities, lack of physical space, materials, supplies, and consumables), resistance to change (professional jealousy of other disciplines and duplication of tasks), staff salaries, lack of training, not trusted with expanded duties, and attitude of patients (resistance to nursing care).

Conclusions

By understanding the perceptions of nursing professionals, we can identify key elements for the successful expansion of nursing functions through expansion of the competencies of operational staff. Reorganization and proper management at different levels of decision-making will be necessary.

Influence of the duration of type 2 diabetes mellitus on colorectal cancer outcomes

Type 2 diabetes mellitus (T2DM) is a progressive disease, which affects colorectal cancer (CRC) survival. However, data on the relationship between CRC survival and T2DM duration is scarce and controversial. A retrospective observational study was conducted. Sub-cohorts were created based on the duration of T2DM as follows, ≤ or > 5/10/15/20 years. 204 of the 817 (24.95%) included study participants had T2DM at any point of CRC. 160 of the 204 CRC + T2DM patients had detailed T2DM duration data. At the time of CRC diagnosis, 85, 50, 31, and 11 patients had T2DM for > 5/10/15/20 years, respectively, which increased to 110, 71, 45, and 17 during the course of the study. Despite constant glycated hemoglobin values throughout the study, shorter overall and disease-specific survival times were observed for the > 5/10/15 years cohorts and longitudinal survival modeling techniques confirmed the significant effect of T2DM duration in all cohorts. While in the first 3 years after CRC diagnosis, the best survival was found for the ≤ 5 years cohort, all diabetes cohorts had the same survival thereafter. T2DM duration affected CRC survival significantly, therefore, a closer follow-up of this sub-populations is suggested.
