A team of five experts from across Spain got together to reach a consensus on a set of recommendations for how to best manage atypical hemolytic uremic syndrome (aHUS) in adults. The consensus offers guidance for doctors with less experience in managing the disease. It covers the entire patient…

A teenager with a mutation in the C3 gene developed atypical hemolytic uremic syndrome (aHUS), which manifested as bleeding in the lungs, after undergoing kidney transplant surgery. According to clinicians, a correct and timely diagnosis in a case like this is essential for improving treatment outcomes. “In patients presenting…

A delay in diagnosing and treating a woman with pregnancy-related atypical hemolytic uremic syndrome (aHUS) may have contributed to her kidney failure, a U.S. case study suggests. Her condition was first thought to be thrombotic thrombocytopenic purpura (TTP), a related blood disorder. Until she was finally diagnosed correctly…

A rare mutation in the CFHR5 gene may have led to the excessive activation of the immune complement system, triggering atypical hemolytic uremic syndrome (aHUS) in a 5-year-old girl, a case study reports. The mutation in CFHR5 (which stands for complement factor H-related protein 5) was found to reduce…

A mutation in the complement factor I (CFI) gene can lead in rare cases to both atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy, two complement-mediated kidney diseases, a case study in Japan shows. “Overlapping [aHUS] and C3 glomerulopathy with complement factor I mutation is very rare, especially in…

Intensive treatment with anti-vascular endothelial growth factor (anti-VEGF) medications — commonly used to treat disorders causing vision impairments — are thought to have led to the onset of atypical hemolytic uremic syndrome (aHUS) in a man in his 40s.
