Summary
Cardiovascular abnormalities, including hypertension and left ventricular hypertrophy, may occur in X-linked hypophosphatemia (XLH) patients. Close monitoring for these conditions is recommended.
Area of Science:
- Pediatric Nephrology
- Cardiovascular Medicine
- Medical Genetics
Background:
- X-linked hypophosphatemia (XLH) treatment can cause hypercalcemia and nephrocalcinosis.
- Cardiovascular abnormalities are not previously reported in XLH patients.
Purpose of the Study:
- To evaluate cardiovascular status in patients with X-linked hypophosphatemia.
- To investigate potential cardiovascular complications in XLH.
Main Methods:
- Assessed cardiovascular status in 13 XLH patients.
- Utilized electrocardiogram and ultrasonography for left ventricular hypertrophy diagnosis.
- Performed exercise stress testing to evaluate blood pressure response.
Main Results:
- All patients had mild to moderate nephrocalcinosis.
- Left ventricular hypertrophy diagnosed in 7/13 children.
- XLH patients showed abnormal diastolic blood pressure increase during exercise stress testing.
Conclusions:
- Patients with XLH may develop hypertension and left ventricular hypertrophy.
- Further investigation into the mechanisms and therapeutic guidelines for XLH cardiovascular complications is needed.
- Close monitoring of XLH patients for cardiovascular abnormalities is recommended.
