Podocyturia in paediatric patients with Fabry disease

Area of Science:

• Nephrology
• Genetics
• Pediatrics

Background:

• Fabry disease (FD) is an X-linked hereditary disorder caused by deficient alpha-galactosidase A enzyme activity.
• Kidney involvement is a major complication of FD, often leading to progressive renal damage.

Purpose of the Study:

• To quantify podocyturia in pediatric FD patients and compare it to healthy controls.
• To determine the relationship between podocyturia and pathological albuminuria in FD.
• To identify risk factors for pathological albuminuria in FD patients.

Main Methods:

• An analytical, observational study comparing 11 pediatric FD patients with 20 healthy controls.
• Podocytes were identified using synaptopodin staining.
• Statistical analysis was performed to compare podocyturia, albuminuria, and risk factors.

Main Results:

• FD patients showed significantly higher podocyturia than controls (p=0.001).
• Podocyturia strongly correlated with albuminuria in FD patients (r=0.8354).
• Key risk factors for pathological albuminuria were podocyturia (OR: 14) and age over 10 (OR: 18).

Conclusions:

• Podocyturia serves as an early indicator of renal damage in pediatric FD.
• This marker precedes and is proportional to the development of pathological albuminuria.
• Early detection of podocyturia can aid in monitoring and managing kidney health in FD.
