Insights
This study surveyed pediatric renal disorders in Venezuela, finding urinary tract infections, metabolic issues, and glomerulonephritis as most common. These findings highlight the wide spectrum of kidney diseases in children.
Area of Science:
- Pediatric Nephrology
- Epidemiology
- Public Health
Background:
- Renal disorders in children represent a significant global health concern.
- Understanding the specific epidemiological landscape of pediatric kidney diseases is crucial for targeted healthcare interventions.
Purpose of the Study:
- To present epidemiological data on renal disorders among children in Venezuela.
- To identify the prevalence and categories of kidney diseases in a pediatric population.
Main Methods:
- A multicenter epidemiological study was conducted across 14 Venezuelan centers.
- Data were collected from January to December 1998, encompassing 3,624 pediatric patients.
- Patients were evaluated for initial outpatient consultations or first hospital admissions.
Main Results:
- Urinary tract infections (32%), metabolic disorders (28%), and glomerulonephritis (9.5%) were the most frequent diagnoses.
- Other significant conditions included urolithiasis (7%), renal tubular acidosis (5.6%), and nephrotic syndrome (4.5%).
- Acute renal failure (2.8%) was often linked to dehydration, birth asphyxia, or septicemia.
Conclusions:
- The spectrum of pediatric renal disorders in Venezuela is broad, with commonalities to both developed and developing nations.
- These epidemiological insights are vital for informing national healthcare policies and improving pediatric kidney care.
- The study underscores the need for continued surveillance and research into childhood kidney diseases.
Abstract:
The present study reports epidemiological data on renal disorders in children in Venezuela. Information was obtained from 14 centers for the period January through December 1998. A total of 3,624 patients were evaluated as either a first outpatient consultation or as a first hospital admission. Nearly 70% of the patients could be grouped in one of the following categories: (1) urinary tract infections (32%), with detection of abnormalities of the urinary tract in 25%, (2) metabolic disorders (28%), mainly idiopathic hypercalciuria and hyperuricosuria, (3) glomerulonephritis (9.5%). The other 30% corresponded to urolithiasis 7%; renal tubular acidosis 5.6%; nephrotic syndrome 4.5%; primary hematuria 4.2%; acute renal failure 2.8% (43% were secondary to acute dehydration, 15% to birth asphyxia, 14% to septicemia, and 23% to multiple factors); chronic renal failure 1.6% (secondary to glomerulopathies, predominantly focal glomerulosclerosis, structural abnormalities of the urinary tract, hereditary disorders, and renal hypoplasia/dysplasia); miscellaneous diseases 4.8%. Hence, the spectrum of renal disorders in Venezuela is wide, sharing similarities with countries of both the developed and developing world. These data will hopefully contribute to the development of national healthcare policies appropriate to the epidemiology of the country.
