Chronic renal failure in Iranian children

Area of Science:

• Pediatric Nephrology
• Urology
• Public Health

Background:

• Chronic renal failure (CRF) in children presents unique challenges in diagnosis and management.
• Understanding the etiological spectrum of pediatric CRF is crucial for targeted interventions.
• Congenital urological abnormalities and hereditary nephropathies are significant contributors to pediatric kidney disease.

Purpose of the Study:

• To investigate the causes and characteristics of chronic renal failure (CRF) in a cohort of Iranian children.
• To identify the most prevalent etiologies of pediatric CRF in the region.
• To compare the findings with international data and suggest preventive strategies.

Main Methods:

• Retrospective analysis of 166 Iranian children diagnosed with CRF between July 1991 and June 1999.
• Data collection included patient demographics, age at onset, etiology of CRF, and treatment modalities.
• Etiological categories included congenital urological malformations, hereditary nephropathy, glomerular diseases, and others.

Main Results:

• The mean age at CRF onset was 7.9 years.
• Congenital urological malformations were the most common cause (78 cases), followed by hereditary nephropathy (21%).
• Glomerular diseases accounted for 10% of cases; high rates of cystinosis and primary hyperoxaluria were noted, potentially linked to consanguinity. Primary reflux prevalence was high compared to Western data.

Conclusions:

• Congenital urological malformations are the predominant cause of pediatric CRF in Iran.
• Hereditary nephropathies and specific metabolic disorders like cystinosis and hyperoxaluria are also significant contributors.
• Early detection and management of urinary tract infections are recommended to decrease the incidence of reflux-induced CRF.
