Insights

Infants with acute or chronic renal failure (ARF/CRF) have high mortality, but renal replacement therapy offers good survival chances for those without severe comorbidities. Kidney transplants in infants show promising long-term outcomes.

Area of Science:

  • Pediatric Nephrology
  • Renal Medicine
  • Infant Health

Background:

  • Analyzed aetiology and outcomes of acute renal failure (ARF) and chronic renal failure (CRF) in infants.
  • Retrospective study of children under 1 year with serum creatinine >100 mumol/l.

Purpose of the Study:

  • To evaluate the causes and survival rates of infants with ARF and CKD.
  • To assess the effectiveness of renal replacement therapy (RRT) in this population.

Main Methods:

  • Followed 119 infants (<1 year) with elevated creatinine (1997-2004).
  • Classified 70 infants with ARF and 49 with chronic kidney disease (CKD) stages 3-5.
  • Documented causes of renal failure, treatments (dialysis, kidney transplant), and outcomes.

Main Results:

  • Congenital diseases caused 41% of renal failure; acquired diseases caused 59%.
  • ARF causes included cardiac, prematurity, and septic conditions; 37% mortality unrelated to kidney function.
  • For CKD, 21/49 infants received dialysis; 23/49 underwent kidney transplant (RTx) with 95.5% 5-year survival. Non-RTx CKD survival was 63%.

Conclusions:

  • Renal replacement therapy provides good survival for infants without life-threatening comorbidities.
  • Infant survival with CKD treated in the first year rivals that of older children.

Acute 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...

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute Kidney Injury III: Clinical Manifestations

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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Acute Kidney Injury V: Interprofessional Care

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...
