Treatment of Renal Sarcoidosis with Hypercalciuria or Mild Hypercalcemia When Initial Dietary Measures Have Not Normalized Calcium

Clinical Scenario

This protocol addresses renal sarcoidosis presenting with hypercalciuria or mild hypercalcemia — serum calcium at or below 11 mg/dl — in patients without nephrolithiasis.

When Initial Measures Fall Short

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.

Next-Line Approach

When lifestyle and dietary interventions have been inadequate, a specific pharmacologic agent may be considered for persistent hypercalciuria. The full selection criteria, monitoring parameters, and complete regimen are available in the structured protocol.

Treatment goal: Normalization of serum and urine calcium levels.

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.
