Fact or Fiction: Primary Hyperoxaluria

Brad Schwartz, DO


August 25, 2023

Primary hyperoxaluria (PH) is a group of autosomal recessive disorders of glyoxylate metabolism that cause overproduction of endogenous oxalate, potentially leading to kidney stones. If hepatic oxalate production exceeds renal removal, systemic oxalate storage in various tissues can lead to life-threatening multiorgan disease.

The prevalence of PH is slightly less than 1000 persons in the United States, and the disease's rarity, combined with its heterogeneous presentation, presents a diagnostic challenge. The first effective pharmacologic treatments for PH — RNA interference (RNAi) therapies — have recently become available and have begun to have an impact on the management of PH.
