Heterozygous Loss-of-Function SEC61A1 Mutations Cause Autosomal-Dominant Tubulo-Interstitial and Glomerulocystic Kidney Disease with Anemia.

Autosomal-dominant tubulo-interstitial kidney disease (ADTKD) encompasses a group of disorders characterized by renal tubular and interstitial abnormalities, leading to slow progressive loss of kidney function requiring dialysis and kidney transplantation. Mutations in UMOD, MUC1, and REN are responsible for many, but not all, cases of ADTKD. We report on two families with ADTKD and congenital anemia accompanied by either intrauterine growth retardation or neutropenia.

Effect of dialyser membrane pore size on plasma homocysteine levels in haemodialysis patients.

Background: Hyperhomocysteinaemia is a putative risk factor for atherothrombotic cardiovascular disease in the haemodialysis population. High-dose vitamin B therapy does not entirely normalize elevated plasma total homocysteine (tHcy) levels in haemodialysis patients. Alternative therapies to reduce tHcy further are therefore required.

Renal angiomyolipoma in association with pulmonary lymphangioleiomyomatosis.

The authors report on a premenopausal female hemodialysis patient with relapsing pneumothorax, in whom the diagnosis of pulmonary lymphangioleiomyomatosis (LAM) was made. Ten years earlier, she had retroperitoneal bleeding from a kidney tumor corresponding to an angiomyolipoma (AML). The association between renal AML and pulmonary LAM is reviewed.
