Insights
Acute renal failure (ARF) in children is often caused by sepsis. While dialysis improves outcomes, comorbidities significantly impact prognosis, with extrarenal issues causing most deaths.
Area of Science:
- Pediatric Nephrology
- Critical Care Medicine
Context:
- Acute renal failure (ARF) management in children has evolved significantly.
- Retrospective analysis of 35 pediatric ARF cases over 15 years.
Purpose:
- To analyze the etiological spectrum of ARF in children.
- To evaluate evolutionary patterns and influencing factors of ARF.
- To assess treatment modalities and their impact on outcomes.
Summary:
- Sepsis (31.4%) and hemolytic uremic syndrome (17.1%) were dominant ARF etiologies.
- Conservative treatment was used in 48.5% of cases; 51.5% required renal replacement therapy (hemodialysis 42.8%, peritoneal dialysis 8.5%).
- Global mortality was 22.8%, but 44.44% in dialyzed patients, with deaths attributed to non-renal causes like hepatic failure, oncology, and neurological damage.
Impact:
- ARF prognosis in children is strongly influenced by comorbid conditions.
- Dialysis has improved therapeutic results, shifting mortality causes to extrarenal factors.
- Understanding ARF etiology and risk factors is crucial for improving pediatric critical care.
Abstract:
The medical care of children with acute renal failure and the necessity of the substituting the renal functions has dramatically modified over the past 15 years. The study has been conducted retrospectively on 35 children diagnosed with acute renal failure (ARF), for analyzing the etiological spectrum, the evolutionary patterns and the influence factors of the ARF evolution. The following parameters have been taken into consideration: ARF etiology, hTA/HTA, oliguria, level of serum creatinine, the type of treatment (renal substitution by hemodialysis, peritoneal dialysis, or conservative treatment). The ARF etiology is dominated by the sepsis (31.4%) and by the hemolytic and uremic syndrome (17.1%). The treatment applied was conservative in 48.5% of the cases; 51.50% of the patients were in critical state and required extrarenal substitution by hemodialysis--42.8%--and peritoneal dialysis--8.5%. Global mortality is reduced (22.8%), but in the dialysed patients it is of 44.44%. The main death causes were: severe hepatic failure, oncological diseases, severe neurological damage and hemodynamic damages. In conclusion, the ARF prognosis in children is influenced by the comorbidity states. Dialysis has improved the therapeutic results in the currently presented lot, the death causes being extrarenal.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
