Different approaches to long-term treatment of aHUS due to MCP mutations: a multicenter analysis.

Background: Atypical hemolytic uremic syndrome (aHUS) is a rare, life-threatening microangiopathy, frequently causing kidney failure. Inhibition of the terminal complement complex with eculizumab is the only licensed treatment but mostly requires long-term administration and risks severe side effects. The underlying genetic cause of aHUS is thought to influence the severity of initial and recurring episodes, with milder courses in patients with mutations in membrane cofactor protein (MCP).

Prevalence, morbidity, and therapy of hepatitis E virus infection in pediatric renal allograft recipients.

Background: Hepatitis E virus (HEV) infection in immunocompromised patients such as solid organ transplant recipients may bear a high risk of becoming a chronic infection with progression to liver cirrhosis. So far, data on HEV infection in pediatric renal transplant recipients are limited.

Methods: This single-center cohort study investigated period prevalence, morbidity, and treatment of HEV infection in 90 pediatric renal allograft recipients aged 9.

Comparison of two different modes of molecular adsorbent recycling systems for liver dialysis.

Background: In children acute liver failure is a rare but life-threatening condition from which two-thirds do not recover with supportive therapy. Treatment is limited by the availability of liver transplants. Molecular adsorbent recirculating system (MARS) dialysis is a bridge to transplantation that enhances the chances of survival during the waiting period for a transplant, although it cannot improve survival.

Combined NGS approaches identify mutations in the intraflagellar transport gene IFT140 in skeletal ciliopathies with early progressive kidney Disease.

Ciliopathies are genetically heterogeneous disorders characterized by variable expressivity and overlaps between different disease entities. This is exemplified by the short rib-polydactyly syndromes, Jeune, Sensenbrenner, and Mainzer-Saldino chondrodysplasia syndromes. These three syndromes are frequently caused by mutations in intraflagellar transport (IFT) genes affecting the primary cilia, which play a crucial role in skeletal and chondral development.

beta-Arrestin2 mediates nephrin endocytosis and impairs slit diaphragm integrity.

beta-Arrestins mediate internalization of plasma membrane receptors. Nephrin, a structural component of the glomerular slit diaphragm, is a single transmembrane spanning receptor and belongs to the family of adhesion molecules. Its mutation causes a hereditary nephrotic syndrome.

Novel approaches to analyse glomerular proteins from smallest scale murine and human samples using DIGE saturation labelling.

Loss of renal function is often associated with the injury of kidney glomeruli. It is therefore necessary to understand the mechanisms leading to progressive glomerular diseases; this may be addressed using proteomics. Until now, however, analysis of the glomeruli proteome using 2-DE has been technically hampered by low protein yields from scarce samples.
