Eculizumab in atypical haemolytic-uraemic syndrome allows cessation of plasma exchange and dialysis

Clin Kidney J. 2012 Feb;5(1):34-6. doi: 10.1093/ndtplus/sfr174. Epub 2012 Jan 30.


Disorders in complement regulation are a major cause of atypical haemolytic-uraemic syndrome (aHUS). Eculizumab, a monoclonal antibody targeting complement C5 and blocking the terminal complement cascade, should theoretically be useful in this disease, particularly when associated with specific complement pathway anomalies such as Factor H deficiency. Eculizumab is emerging as an effective treatment for post-transplant aHUS recurrence and may have a role in treating de novo aHUS, halting the haemolytic process. In this case report, we describe the fourth case of aHUS treated with eculizumab. In our patient, with a known complement Factor H mutation, not only has the disease process become quiescent but also this therapy has led to significantly improved renal function so that dialysis is no longer necessary.
