Patched — Typical Vs Atypical Hemolytic Uremic Syndrome

Hemolytic Uremic Syndrome (HUS) is a complex group of rare blood disorders characterized by a triad of symptoms: (destruction of red blood cells), thrombocytopenia (low platelet count), and acute kidney injury (AKI) . While they share these core features, typical and atypical HUS differ significantly in their causes, progression, and treatment.

| Feature | Typical HUS (Shiga-Toxin) | Atypical HUS (aHUS) | | :--- | :--- | :--- | | | Infectious (STEC E. coli ) | Genetic / Complement Dysregulation | | Prodrome | Bloody Diarrhea (D+) | Often absent; insidious onset | | Age Group | Predominantly children | All ages (adults and children) | | Mechanism | Toxin-mediated endothelial damage | Uncontrolled immune system activation | | Seasonality | Summer months (picnic season) | No seasonal pattern | | Primary Treatment | Supportive care (fluids, dialysis) | Complement inhibitors (e.g., Eculizumab) | | Recurrence | Rare (immunity to strain develops) | Common (lifelong predisposition) | | Prognosis | Generally good; high recovery rate | Historically poor; improved with biologics | typical vs atypical hemolytic uremic syndrome

Before the era of modern medicine, aHUS had a grim prognosis, with nearly 50% mortality or progression to end-stage renal disease (ESRD). Hemolytic Uremic Syndrome (HUS) is a complex group

Hemolytic uremic syndrome (HUS) is a complex and heterogeneous disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. It is a leading cause of acute kidney injury and end-stage renal disease in children and adults. HUS can be broadly classified into two categories: typical and atypical. coli ) | Genetic / Complement Dysregulation |
