Abstract
We describe two siblings (female and male) with progressive tubulo-interstitial nephropathy and cholestatic liver disease. The main characteristics were progressive renal failure and elevated liver enzymes (AST, ALT and γ-GT). Dialysis was started at the age of 1.9 and 6.5 years, respectively. Renal histology disclosed sclerosed glomeruli and atrophic tubules; the interstitium was fibrotic and infiltrated by lymphocytes. Endoscopic retrograde cholangiopancreatography revealed segmental irregularities and narrowing of the intrahepatic bile ducts, consistent with early primary sclerosing cholangitis. Liver histology showed enlarged portal triads, mild proliferation and inflammation of bile ducts, and fibrosis. At 5.9 years the girl underwent a successful renal transplantation whereas the boy is still on dialysis.
Conclusion The association of progressive tubulo-interstitial nephropathy and cholestatic liver disease, consistent with early primary sclerosing cholangitis, constitutes a distinct autosomal recessive entity.
