Abstract:
We report an adult male with classic propionic acidemia (PA) who developed chronic kidney disease in the third decade of his life. This diagnosis was recognized by an increasing serum creatinine and confirmed by reduced glomerular filtration on a (99m)Tc-diethylenetriamine pentaacetate (DTPA) scan. Histopathology of the kidney showed moderate glomerulo- and tubulointerstitial fibrosis with very segmental mesangial IgA deposits. This is the second reported case of kidney disease in an individual with propionic acidemia possibly indicating that chronic kidney disease may be a late-stage complication of propionic acidemia. Additionally, this is the first description of the histopathology of kidney disease in an individual with propionic acidemia. As more cases emerge, the clinical course and spectrum of renal pathology in this disorder will be better defined.

Renal Regulation of Acid-Base Balance
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
