A case of late-onset primary hyperoxaluria

Large joint destructive arthropathy and tumoral calcinosis associated to primary oxalosis: case report and literature review

A case of destructive arthropathy of hips and shoulders with tumoral calcinosis associated with calcium oxalate deposits in a patient with primary oxalosis and end stage renal disease on hemodialysis.

An unexpected cause of progressive renal failure in a 66-year-old male after liver transplantation: secondary hyperoxaluria

BACKGROUND

Hyperoxaluria is a rare metabolic disorder characterized by calcium oxalate deposition in different tissues. It is caused either by an inherited disease of oxalate metabolism [primary hyperoxalurias (PH)] or by an acquired disturbance (secondary hyperoxaluria).

CASE

We report here an atypical presentation of enteric hyperoxaluria-induced renal failure that occurred after liver transplantation. Despite adapted treatment and intensive haemodialysis, the patient did not recover. This case allows the reviewing of the multiple pathophysiological mechanisms involved in this disease.

CONCLUSION

Oxalate nephropathy should be considered in the differential diagnosis of acute renal failure, especially when previous renal impairment and fat malabsorption are present. We suggest performing renal biopsy early to allow a prompt diagnosis and therapeutic intervention.
