Chronic hemolysis and renal iron deposition, which is a particular risk in PNH when complement inhibition therapy is delayed or not available, may result in acute tubular injury or acute kidney injury (AKI). Consultation with a nephrologist may be indicated to help manage these cases. Continuous renal replacement therapy (CRRT) is one of the best options for the treatment of PNH-associated AKI. Dialysis techniques may include immunoadsorption, dedicated hemodialysis filters that use convective techniques, backfiltration, or coupled plasma filtration adsorption (CPFA). [36]
