25-hydroyxvitamin D and 1, 25-dihydroxyvitamin D levels should be assessed at least once to determine if pharmacological supplementation is needed.
Pharmacological doses (50,000 IU) of vitamin D should not be used for the primary purpose of reducing autoimmune disease or cancer risk.
In patients with an estimated glomerular filtration rate (eGFR) of >60 mL/min/1.73 m 2 and sarcoidosis:
Treatment of osteoporosis or osteopenia. Pharmacological vitamin D therapy (50,000 IU) should be considered only if 1, 25-dihydroxyvitamin D levels are low and there is no evidence of hypercalciuria (>300 mg/24 h) or hypercalcemia.
Primary prevention of glucocorticoid-induced osteoporosis. Bisphosphonate therapy should be utilized as the primary treatment strategy in patients starting glucocorticoid therapy. As with treatment of osteoporosis, nonpharmacological doses of vitamin D (200 to 400 IU) or calcium supplementation can be used in patients without hypercalciuria or hypercalcemia.
Pharmacological doses of vitamin D should not be used in patients with an eGFR <60 mL/min/1.73 m2 without frequent assessment of serum calcium and multidisciplinary consultations (nephrology, bone, and mineral).
