Summary
Glomerular hyperfiltration, an early sign of kidney injury in diabetes and obesity, is often overlooked. Recognizing and managing this condition in "diabesity" may help prevent irreversible kidney damage.
Area of Science:
- Nephrology
- Endocrinology
- Metabolic Diseases
Background:
- Glomerular hyperfiltration is an early indicator of kidney disease in diabetes and obesity.
- This condition, termed "diabesity," merges type 2 diabetes and obesity, potentially causing reversible kidney injury.
- Hyperfiltration is underrecognized in clinical nephrology, despite its link to albuminuria and declining glomerular filtration rate (GFR).
Purpose of the Study:
- To advocate for the re-evaluation of glomerular hyperfiltration as a clinically relevant phenotype in diabesity.
- To propose practical methods for identifying hyperfiltration in clinical practice.
- To outline a strategy for the clinical recognition and therapeutic targeting of hyperfiltration.
Main Methods:
- Review of recent clinical evidence and prospective studies.
- Proposal of diagnostic approaches: percentile-based thresholds, protein loading tests, and renal resistive index variation.
- Analysis of hyperfiltration's association with albuminuria and GFR decline.
Main Results:
- Glomerular hyperfiltration is a significant, yet underappreciated, contributor to kidney injury in diabesity.
- Existing chronic kidney disease (CKD) staging systems do not incorporate hyperfiltration.
- Clinical evidence underscores the prognostic importance of hyperfiltration, necessitating its integration into risk assessment.
Conclusions:
- Hyperfiltration in diabesity warrants clinical recognition as a key phenotype.
- Practical diagnostic tools and therapeutic strategies are needed for hyperfiltration management.
- Integrating hyperfiltration assessment into routine care can improve risk stratification and patient outcomes.

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration...

01:29Hyperglycemia
2
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose...

01:22Diabetes Insipidus II: Pathophysiology
7
Normally, water balance is maintained through three interconnected mechanisms: the hypothalamic thirst center, the synthesis and release of antidiuretic hormone (ADH, or vasopressin), and the kidneys' responsiveness to this hormone. ADH is synthesized in the hypothalamus, released from the posterior pituitary, and acts on the distal nephron, allowing water reabsorption and concentrated urine production.Diabetes Insipidus and Its TypesIn diabetes insipidus (DI), this regulatory system is...

01:29Diabetes Insipidus I: Introduction
6
Definition Diabetes insipidus is a disorder marked by the production of large amounts of dilute urine because of impaired vasopressin production, release, or kidney response. The lack of effective vasopressin action limits water reabsorption in the renal collecting ducts, which leads to excessive urinary water loss and intense thirst.Clinical PresentationIndividuals with diabetes insipidus report persistent thirst and very high urine output. In severe cases, fluid intake can reach up to 20...

01:16Antihypertensive Drugs: Action of Diuretics
2.9K
Diuretics are antihypertensive drugs used to treat hypertension resulting from sodium and water retention. Sodium, vital for fluid balance and nerve or muscle function, is regulated by the kidneys through millions of nephrons. Blood enters nephrons via afferent arterioles, which branch into capillaries called glomeruli. These filter blood plasma, allowing water and solutes, like sodium ions, to pass through capillary walls into Bowman's capsule. The filtrate then flows through various...

01:24Nephrotic Syndrome I : Introduction
1.1K
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...
