Anti-factor H autoantibody-associated hemolytic uremic syndrome: the earlier diagnosed and treated, the better (Commentary)

Atypical hemolytic uremic syndrome (HUS) secondary to anti-factor H autoantibodies has a poor prognosis. The study by Sinha et al. of a large cohort of Indian children makes a substantial contribution to improved management of this form of HUS by showing that standardized titration of anti-factor H autoantibodies is applicable worldwide and that early treatment initiation and guidance of maintenance treatment by autoantibody titer monitoring significantly improve outcomes.
