Background. Atypical hemolytic uremic syndrome (aHUS) is a disease with uncontrolled activation of the alternative complement pathway leading to the development of complement-mediated thrombotic microangiopathy (TMA). A typical triad of aHUS includes acute kidney injury (AKI), nonimmune hemolytic anemia, and consumptive thrombocytopenia.
Objective. Demonstration of the difficulties of diagnosing and treating aHUS.
Clinical case. Patient D., 19 years old, AKI sharply developed after a viral infection. Symptoms characteristic of aHUS included anemia, thrombocytopenia and AKI. Discussion of the diagnosis of TMA within the framework of aHUS became possible due to the results of the patient’s examination for ADAMTS-13, complete restoration of renal function during plasma therapy.
Conclusion. It is extremely important for doctors to be aware of the possibilities of timely diagnosis of aHUS; adequate pathogenetic therapy provides complete restoration of the function of the affected organs.
