Summary
Premature infants face a higher risk of chronic kidney disease (CKD) due to impaired nephrogenesis. Early renal assessment is crucial for preterm infants to monitor kidney health and improve long-term outcomes.
Area of Science:
- Neonatology
- Nephrology
- Developmental Biology
Background:
- Improved healthcare increases survival rates for premature infants.
- Prematurity may lead to long-term health issues, including kidney disease.
- Chronic kidney disease (CKD) risk in preterm infants requires further investigation.
Purpose of the Study:
- To determine if premature infants have an increased risk of developing chronic kidney disease (CKD).
- To review existing evidence on the relationship between prematurity and kidney impairment.
Main Methods:
- A comprehensive literature review was conducted.
- Searched databases included PubMed and the Cochrane Library.
- Keywords used were "prematurity," "kidney," "nephrogenesis," "oligonephropathy," and "kidney impairment" for articles published since 1990.
Main Results:
- Evidence suggests prematurity causes oligonephropathy, independent of or alongside intrauterine growth restriction.
- Animal studies indicate abnormal glomeruli development in premature neonates.
- Postnatal renal impairment affects 8-24% of preterm infants, indicating impaired nephrogenesis.
Conclusions:
- Premature infants are at significant risk for developing chronic kidney disease (CKD).
- Current follow-up guidelines for preterm infants should include renal assessments.
- Further longitudinal studies are needed to establish the exact incidence of CKD in this population.

01:24Nephrotic Syndrome I : Introduction
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 fluid...
01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:28Diabetic Nephropathy
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 occur due to afferent arteriolar...
01:10Nephrons
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 happens...
01:29Acute Kidney Injury II: Pathophysiology
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...
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
