This protocol addresses renal sarcoidosis presenting with hypercalciuria or mild hypercalcemia — serum calcium at or below 11 mg/dl — in patients without nephrolithiasis.
The first approach for isolated hypercalciuria and mild hypercalcemia is reduction in calcium intake, increased fluid intake, and avoidance of sun exposure. When these measures do not achieve a sufficient reduction in urine calcium or serum calcium, this next-line protocol applies.
In isolated hypercalciuria, treatment may begin with a reduction in calcium intake, increased fluids and avoidance of sun.
Mild hypercalcemia may also be treated with a reduction in dietary calcium and increased fluid intake.
Occasionally, hydroxychloroquine may be effective at 200-400 mg daily for more significant hypercalciuria.
