Diabetic Nephropathy

Diabetic Nephropathy is a serious complication of diabetes mellitus that involves kidney damage.
It is characterized by persistent albuminuria, progressive decline in glomerular filtration rate, and elevated blood pressure.
Early detection and management of diabetic nephropathy is crucial to prevent or delay the progression to end-stage renal disease.
The etiology involves a complex interplay of genetic, metabolic, and hemodynamic factors.
Effective treatment strategies focus on glycemic control, blood pressure management, and the use of angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers.
Continued research is needed to better understand the pathologenesis and identify novel therapeutic targets for this disabling condition.

The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) conducted the study under a cooperative agreement with the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). CKD-EPI collaborators provided data from clinical research studies and clinical populations.3 (link) GFR measurements were based on urinary or plasma clearance of exogenous filtration markers. Data from studies of urinary clearance of iothalamate were used for development and internal validation, and data from studies of other filtration markers were used for external validation. We included 13 studies with 5352 participants, who were randomly divided into separate data sets for development (3522) and internal validation (1830) (see Table S1a in the Supplementary Appendix, available with the full text of this article at NEJM .org). We included 5 other studies with 1119 participants for external validation (Table S1b in the Supplementary Appendix). We excluded studies involving transplant recipients because our preliminary analyses showed large variations among these studies in the relationship between serum cystatin C levels and measured GFR. The institutional review boards of all participating institutions approved the study.
The NIDDK was substantially involved in the design of the study and in the collection, analysis, and interpretation of the data; the NIDDK was not required to approve the final manuscript before submission for publication. The first author had full access to all the data in the study, vouches for the integrity of the data and the accuracy of the data analysis for the CKD-EPI database, and wrote the first draft of the manuscript. For a list of collaborators who provided data, see the Supplementary Appendix.

Body characteristics for participants in the TARA study are shown in Table 1. Subjects were 223 African Americans (Table 1, 43.5% male), age 35 years (34.8 ± 7.7), range 20–50 years, BMI 30.0 ± 7.7, range 18.5–54.7 kg/m2. The BMI range of TARA participants was similar to that of the BetaGene subjects. Data from the TARA subjects have been previously reported (18 (link),19 (link)). Subjects were born in the United States and each subject reported that both parents were African-American. Oral glucose tolerance tests revealed previously unknown impaired glucose tolerance in 25% and diabetes in 2%. Twenty percent were hypertensive. Women were premenopausal; 41% of the females were obese. Recruitment was accomplished through flyers, newsletters, and websites. The institutional review board of National Institute of Diabetes and Digestive and Kidney Disease (NIDDK) approved the study, and all subjects gave informed consent.
Hip circumference in all TARA participants was measured by a single observer (N.G.S.) over nonrestrictive underwear or light-weight shorts, at the level of the maximum extension of the buttocks posteriorly in a horizontal plane. The mean of the three determinations was recorded. Similar to the BetaGene study, whole-body composition measurements were performed with a Hologic QDR4500A dual-energy X-ray absorptiometer (Hologic) in the array mode using software version 5.71A.

Each participating center will enroll approximately 250 consecutive individuals over a 5-year period from 2011 until 2015, totaling 2,450 adult patients with CKD who provide written informed consent. The participating individuals will be monitored for approximately 10 years until death or until ESRD occurs.
The KNOW-CKD will enroll ethnic Korean patients with CKD who range in age between 20 years and 75 years. The CKD stages from 1 to 5 (predialysis), based on the eGFR, is calculated using the four-variable Modification of Diet in Renal Disease (MDRD) equation as follows:
eGFR (ml/min per 1.73 m2) = 175 × [serum Cr (mg/dl)] -1.154 × [age]-0.203 × [0.742 if female] × [1.212 if black], using serum creatinine concentrations measured at a central laboratory and an assay traceable to the international reference material [12 (link)].
Excluded subjects are those who 1) are unable or unwilling to give written consent, 2) have previously received chronic dialysis or organ transplantation, 3) have heart failure (NYHA class 3 or 4) or liver cirrhosis (Child-Pugh class 2 or 3), 4) have a past or current history of malignancy, 5) are currently pregnant, or 6) have a single kidney due to trauma or kidney donation.
We defined and allocated the specific causes of the CKD into four subgroups: glomerulonephritis (GN), diabetic nephropathy (DN), hypertensive nephropathy (HTN), and polycystic kidney disease (PKD). The definition of the subgroup is defined by the pathologic diagnosis, in the event that the biopsy result is available. Otherwise, the subgroup classification depends on the clinical diagnosis. GN is defined by the presence of glomerular hematuria or albuminuria with or without an underlying systemic disease causing glomerulonephritis. The diagnosis of DN is based on albuminuria in a subject with type 2 diabetes mellitus and the presence of diabetic retinopathy. HTN is defined by the patient’s hypertension history and the absence of a systemic illness associated with renal damage. Unified ultrasound criteria [13 (link)] will be used to diagnose PKD. The other causative diseases will be categorized as ‘unclassified’.

More about "Diabetic Nephropathy"

Diabetic kidney disease (DKD), also known as diabetic nephropathy, is a serious complication of diabetes mellitus (DM) that involves progressive kidney damage.
It is characterized by persistent albuminuria (increased protein in the urine), gradual decline in glomerular filtration rate (GFR), and elevated blood pressure.
Early detection and appropriate management of DKD are crucial to prevent or delay the progression to end-stage renal disease (ESRD).
The underlying etiology of DKD involves a complex interplay of genetic, metabolic, and hemodynamic factors.
Effective treatment strategies focus on achieving optimal glycemic control, effective blood pressure management, and the use of angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs).
Continued research, including the use of animal models like C57BL/6N mice and statistical software like SAS 9.4, JMP 13, and SPSS 15.0, is essential to better understand the pathogenesis of DKD and identify novel therapeutic targets for this disabling condition.
Diabetic kidney disease can also be referred to as diabetic nephropathy (DN), DM-associated kidney disease, or DM-related kidney disease.
Early detection and management are critical, as DKD is a leading cause of ESRD, often requiring dialysis or kidney transplantation.
By understanding the latest research and treatment approaches, healthcare providers can optimize the care and outcomes for patients with this complex and challenging complication of diabetes.
