Abstract:

Background: Thrombotic Microangiopathies (TMA) are not very common diseases characterized by forming small clots in the microvasculature. Atypical Hemolytic Uremic Syndrome (aHUS) is a relatively rare form of primary TMA that is progressive and can lead to end-stage renal involvement. Case: We describe the case of an otherwise healthy 35-year-old woman who developed acute anuric kidney injury with laboratory attributes of TMA after elective induction of labor. Flowcytometry examination demonstrating decreased CD46 fluorescence was used to confirm the diagnosis of aHUS. Conclusion: Flowcytometric CD46 testing represents a new available test capable of shortening the time to aHUS diagnosis and initiation of eculizumab therapy, which may favorably contribute to improving the outcome of patients with this variant of primary TMA.
