Hypercalcemic hypertension in hemodialysis.

D A Sica, A M Harford, E T Zawada

    Clinical Nephrology
    |August 1, 1984
    PubMed
    Summary

    Refractory hypertension in a hemodialysis patient resolved after correcting hypercalcemia caused by vitamin D. This highlights calcium's role in blood pressure regulation for end-stage renal disease patients.

    Area of Science:

    • Nephrology
    • Cardiovascular Medicine
    • Endocrinology

    Background:

    • Long-term hemodialysis patients can develop complex health issues.
    • Hypertension is a common and serious comorbidity in end-stage renal disease (ESRD).
    • Standard treatments for hypertension in ESRD may not always be effective.

    Observation:

    • A 25-year-old female on long-term hemodialysis presented with severe hypertension.
    • The hypertension was resistant to adjustments in dry weight and antihypertensive medications.
    • Hypercalcemia was identified as a potential underlying cause, linked to vitamin D administration.

    Findings:

    • Correction of hypercalcemia led to the normalization of blood pressure.
    • This case suggests a direct link between calcium levels and blood pressure control in ESRD.
    • Vitamin D-induced hypercalcemia can significantly impact cardiovascular status in dialysis patients.

    Implications:

    • Clinicians should consider monitoring calcium levels in hemodialysis patients with refractory hypertension.
    • Understanding the interplay between calcium, vitamin D, and blood pressure is crucial for managing ESRD.
    • This case underscores the importance of individualized treatment approaches in managing complex comorbidities in ESRD.
