Remission of aHUS neurological damage with eculizumab

Atypical haemolytic uraemic syndrome (aHUS) is a rare disease characterized by haemolytic microangiopathic anaemia, thrombocytopaenia and acute onset of renal failure, in the absence of Escherichia coli infection. Renal damage usually progresses to end-stage renal disease (ESRD), sometimes being accompanied by signs of extrarenal thrombotic microangiopathy (TMA). We report a case of full neurological and haematological recovery after eculizumab treatment in a patient with ESRD secondary to chronic aHUS refractory to plasmatherapy while she was under dialysis. It highlights the use of eculizumab for controlling extrarenal manifestations of aHUS in this population.
