[Premature kidneys and oligonephronia: long term repercussion]
Revue Medicale Suisse
|March 20, 2014
Summary
Premature infants with fewer nephrons face higher risks of kidney problems like hypertension and insufficiency. Early detection of markers such as microalbuminuria can guide preventative strategies.
Area of Science:
- Nephrology
- Neonatology
- Pediatric Nephrology
Context:
- Premature infants are born with a reduced number of nephrons (oligonephronia).
- Immature renal function at birth heightens vulnerability to hemodynamic changes, drug toxicity, and nephrocalcinosis.
- Oligonephronia increases the long-term risk of developing hypertension and renal insufficiency in adulthood.
Purpose:
- To highlight the risks associated with reduced nephron number in premature infants.
- To explain the pathogenesis and consequences of nephrocalcinosis in the premature.
- To emphasize the importance of early identification of predictive markers for targeted prevention.
Summary:
- Premature infants with oligonephronia and immature renal function are susceptible to various kidney complications.
- Nephrocalcinosis, linked to renal calcifications and rickets, is a significant concern, exacerbated by excessive vitamin D and calcium intake.
- Early detection of microalbuminuria, hypertension, and hypercalciuria is crucial for implementing preventive measures.
Impact:
- Informing clinical practice for managing premature infants at risk of renal disease.
- Guiding preventative strategies to mitigate long-term renal complications in survivors.
- Enhancing understanding of the relationship between prematurity, nephron number, and kidney health outcomes.

8.2K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

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...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

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...

01:25Chronic Kidney Disease I: Introduction
1.4K
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...
