Insights
Congenital anomalies of the kidney and urinary tract (CAKUT) were the leading cause of end-stage renal failure (ESRF) in Jordanian children. This study highlights the critical need for understanding ESRF aetiology in pediatric populations.
Area of Science:
- Pediatric Nephrology
- Renal Replacement Therapy
- Public Health
Background:
- End-stage renal failure (ESRF) in children presents a significant global health challenge.
- Understanding the specific aetiologies of pediatric ESRF is crucial for developing targeted prevention and treatment strategies.
- Jordanian data on the causes of pediatric ESRF were previously limited.
Purpose of the Study:
- To determine the primary causes of end-stage renal failure (ESRF) in children within Jordan.
- To analyze the distribution of different aetiologies contributing to pediatric ESRF.
- To provide baseline data for future research and clinical interventions in pediatric nephrology in Jordan.
Main Methods:
- A multicentre retrospective study was conducted across five hospitals in Jordan.
- Medical records of 275 children diagnosed with ESRF were reviewed.
- Data collected included patient demographics, aetiology of ESRF, renal replacement therapy (RRT) modality, and patient outcomes.
Main Results:
- Congenital anomalies of the kidney and urinary tract (CAKUT) were the most frequent cause of ESRF (45.8%).
- Heredofamilial disorders (23.2%) and glomerulopathies (26.2%) were the next most common aetiologies.
- The study also detailed specific conditions within these categories, such as neurogenic bladder and focal segmental glomerulosclerosis, and reported on RRT modalities and associated mortality rates.
Conclusions:
- This study provides the first comprehensive report on the aetiology of ESRF in children in Jordan.
- CAKUT, heredofamilial disorders, and glomerulopathies are the predominant causes of pediatric ESRF in the region.
- Findings underscore the importance of addressing these specific aetiologies in pediatric kidney care in Jordan.
Objective:
The purpose of this study was to find out the aetiology of end-stage renal failure (ESRF) in children in Jordan.
Subjects And Methods:
This was a multicentre retrospective study at five participating hospitals. Data collection included medical record review for age, gender, aetiology of ESRF, modality of renal replacement therapy (RRT) and outcome. End-stage renal failure was defined as estimated glomerular filtration rate < 15 mL/min/1.73m2.
Results:
There were 275 children with ESRF: 131males and 144 females. The most common causes of ESRF in children were congenital anomalies of the kidney and urinary tract (CAKUT), 45.8%, heredofamilial disorders, 23.2% and glomerulopathies, 26.2%. Neurogenic bladder, reflux nephropathy and posterior urethral valve accounted for 16.8%, 12.7% and 4.0%, respectively. Amongst the heredofamilial disorders, primary oxalosis and cystic disease accounted for 8.0% and 7.2% of the aetiologies of ESRF, respectively. Focal segmental glomerulosclerosis was the most common histological type amongst the glomerulopathies (10.2%), followed by mesangiocapillary glomerulonephritis (4.7%) and chronic glomerulonephritis (3.0%). The aetiology was unknown in 4% of the cases. The modality of dialysis included isolated peritoneal dialysis (PD) in 30.9%, isolated haemodialysis (HD) in 49.1%, alternating peritoneal and haemodialysis in 9.1%, transplanted in 8.7% and conservative treatment in 1.8%. Death occurred in 57.3% of PD patients versus 34.4% in HD patients.
Conclusions:
This is the first report on the aetiology of ESRF in children in Jordan. The most common aetiologies of ESRF were CAKUT 45.8%, heredofamilial disorders 23.2% and glomerulopathies 22.9%.
