Extrarenal synthesis of calcitriol results from the acquisition by blood monocytes and granuloma macrophages of the ability to convert 25-hydroxy vitamin D3 into 1,25 dihydroxy vitamin D3 (1).
This produces:
Intrarenal calcium deposition may result in renal calculi, nephrocalcinosis, interstitial nephritis and renal failure (2).
Hence 24-hour urinary excretion of calcium should be measured in all patients with sarcoidosis (1).
