Insights

This study developed two risk models to predict stage-3 chronic kidney disease (CKD) in Thai patients with type 2 diabetes mellitus (DM). The models accurately identify individuals at high risk, aiding clinical management and patient education.

Area of Science:

  • Nephrology
  • Endocrinology
  • Public Health

Background:

  • Type 2 diabetes mellitus (DM) is a leading cause of chronic kidney disease (CKD).
  • Predicting CKD progression in diabetic patients is crucial for timely intervention.
  • Thai patients with type 2 DM require specific risk assessment tools.

Purpose of the Study:

  • To identify predictors of stage-3 CKD in Thai patients with type 2 DM.
  • To develop and validate risk prediction models for stage-3 CKD.
  • To provide tools for clinical management and patient education.

Main Methods:

  • Retrospective cohort study of 2178 type 2 DM patients.
  • Cox proportional hazard regression for model development.
  • Model performance evaluated using discrimination (C statistic) and calibration tests.

Main Results:

  • 17.68% of patients developed stage-3 CKD during a median follow-up of 1.29 years.
  • Key predictors identified: age, male sex, urinary albumin to creatinine ratio, estimated glomerular filtration rate, and hemoglobin A1c.
  • Two 3-year risk models (laboratory and simplified) showed good predictive performance (C-statistics 0.890 and 0.812).

Conclusions:

  • Developed two validated 3-year risk models for stage-3 CKD in Thai type 2 DM patients.
  • Models demonstrate good discrimination and calibration.
  • These tools can enhance clinical decision-making and patient counseling for CKD prevention.

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
