- Oxalosis 2

- Glyceric aciduria
- D-glycerate dehydrogenase deficiency

The current management strategy includes high fluid intake, treatment with inhibitors of calcium oxalate crystallization, and temporary intensive dialysis for end-stage renal disease (ESRD) followed by kidney transplantation. Varying success has been reported following transplantation, with recurrence being a real possibility since hyperoxaluria and elevated L-glycerate levels persist. Careful management in the postoperative period, with attention to brisk urine output and use of calcium oxalate urinary inhibitors may help prevent complications.
To date, liver-kidney transplantation has not been used in primary hyperoxaluria type 2. This strategy may be considered, however, as there is more enzyme in the liver than in other tissues. More studies are needed before liver transplantation can be recommended. Other treatment modalities needing further investigation include liver cell transplantation and recombinant gene therapy to replace the missing enzyme.
