[The experience of using the Russian biosimilar of the original drug eculizumab for the treatment of patients with atypical hemolytic-uremic syndrome].

Atypical hemolytic-uremic syndrome (aHUS) is a chronic systemic disease of a genetic nature, which is based on uncontrolled activation of the alternative complement pathway, leading to generalized thrombosis in the vessels of the microvasculature (complement-mediated thrombotic microangiopathy). To date, therapy with eculizumab is the most effective and pathogenetically substantiated method of treating patients with ASH. Using the example of three clinical cases of patients with a verified diagnosis of aHUS, the high efficiency and safety of the worlds first bioanalogue of eculizumab in the treatment of adult patients with aHUS (complement-mediated thrombotic microangiopathy) was demonstrated.
