Limited Treatment Options in Primary Hyperoxaluria with Renal Failure

Primary hyperoxaluria (PH) is a rare autosomal recessive metabolic disorder where serum oxalate levels rise due to overproduction. The kidney tubule is a main target for oxalate deposition, resulting in damage to the organ. Kidney failure is rare in these patients. We present a 67-year-old female with hemodialysis-dependent end-stage renal disease likely due to PH type 2 or 3. With extremely high levels of serum oxalate (60.4 μmol/L), this patient had minimal treatment options for her rare disease. This report details a unique presentation of a rare disease where kidney biopsy was instrumental.
