Atypical Hemolytic Uremic Syndrome (aHUS) – Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2023 To 2033

Atypical Hemolytic Uremic Syndrome (aHUS) is a rare genetic thrombotic microangiopathy. It results from the dysregulation of the alternative complement pathway and is characterized by hemolytic anemia, thrombocytopenia, and acute renal dysfunction. Most cases involve uncontrolled complement activation, damaging endothelial cells. Pathogenic mutations occur in genes related to complement regulation, including CFH, CFI, CD46, C3, and CFB, along with rearrangements in CFH and related genes. Symptoms can manifest at any age, typically appearing suddenly with microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure triggered by respiratory infections or gastroenteritis. In some cases, onset is gradual with recurrent subclinical symptoms like anemia and thrombocytopenia, along with vague symptoms like fatigue and loss of appetite. Roughly half of patients progress to end-stage kidney disease. Diagnosis relies on genetic testing, functional complement protein tests, and sc...
