Would you add an SGLT2 inhibitor to augment diuresis during a hospitalization in a patient with nephrotic syndrome, an eGFR above 30 mL/min/1.73m2, and refractory hypervolemia on an intravenous loop diuretic?

  1. Establish true loop diuretic refractoriness (minimum frequency: BID, the max dose depends on CrCl).
  2. Add sequential diuretics. Metolazone or other thiazide-like diuretics, with without amiloride or spironolactone. (Latter diuretics are preferred if the patient is hypokalemic).
  3. Add 25% albumin if evidence of intravascular volume depletion.
  4. IF severe AKI and truly pan-diuretic refractory, plasmapheresis is suggested.

SGLT2i is generally not needed if the above algorithm is employed.
