The most common types of TMA in children are Shiga toxin-producing <em>Escherichia coli</em>-associated hemolytic uremic syndrome (STEC-HUS) followed by complement-mediated (CM) TMA, <em>Streptococcus pneumoniae</em>-associated hemolytic uremic syndrome (Sp-HUS) and hereditary thrombotic thrombocytopenic purpura (hTTP) and other rare causes.

The etiological differentiation is crucial as eculizumab is a specific therapy with exceedingly good results in CM-TMA.
