Renal abnormalities in the Bardet-Biedl syndrome
The International Journal of Pediatric Nephrology
|September 1, 1982
Summary
Renal abnormalities are a key feature of Bardet-Biedl syndrome (BBS), often presenting early with impaired kidney function. These kidney issues are the primary cause of mortality in BBS patients.
Area of Science:
- Nephrology
- Genetics
- Pediatrics
Background:
- Bardet-Biedl syndrome (BBS) is a rare genetic disorder.
- Renal abnormalities are frequently observed in BBS patients.
- Understanding the spectrum of renal pathology in BBS is crucial for patient management.
Observation:
- This study details four cases of Bardet-Biedl syndrome with significant renal involvement.
- Early signs included polyuria, polydipsia, and impaired renal concentration capacity.
- Urographic findings revealed cystic spaces, lobulation, caliceal clubbing, and caliectasis.
Findings:
- Tubulo-interstitial lesions were present in all four cases.
- Dysplasia and cystic formations were less common.
- No mesangial proliferation or ultra-structural glomerular basement membrane changes were observed.
Implications:
- Renal abnormalities are a cardinal feature of Bardet-Biedl syndrome.
- Kidney disease is the major cause of death in BBS.
- Early recognition and monitoring of renal function are vital for improving outcomes in BBS.
