Table 3 Differentiating features between Wilson disease-related renal tubular acidosis and D-penicillamine induced glomerulonephritis

Wilson disease-related renal tubular acidosis
D-penicillamine induced glomerulonephritis
MechanismCopper induced tubular damageImmune complex deposition
PresentationPrior to starting chelation/during chelationAfter starting chelation
Tests to differentiateNormal anion gap metabolic acidosis, Urine pH, Urine for glucosuria, aminoaciduria, acidification test of urineUrine for proteinuria, autoantibodies for glomerulonephritis, renal biopsy
ChelationTo be continuedTo be stopped
