Type I polyglandular autoimmune syndrome is characterized by the triad
of hypoparathyroidism Addison's disease and chronic mucocutaneous can
didiasis. Chronic active hepatitis has been associated with this syndr
ome but its incidence and severity have not been well documented. We d
escribe a sibship of two patients with type I polyglandular autoimmune
syndrome who presented with autoimmune chronic active hepatitis. The
first patient presented to us with advanced disease and died despite a
n emergent Liver transplant, while the second patient responded to ste
roids. Autoimmune chronic active hepatitis, a major cause of mortality
in this syndrome, can present without symptoms or physical signs of l
iver disease. We suggest periodic screening of liver enzymes in subjec
ts with this syndrome.
