First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving only calcitriol (a form of vitamin D) to 16 children and adults with X-linked hypophosphatemia (XLH) could raise blood phosphate levels and improve bone growth without causing kidney stones. Participants took increasing doses of calcitriol for one year. The goal was to see if this simpler treatment could help manage the disease and support growth in children.
