Answer

Patients with hemolytic-uremic syndrome (HUS) have vascular lesions indistinguishable from those observed in patients with TTP, but the renal vasculature endures the most lesions, with minimal neurologic dysfunction.

HUS is a catastrophic illness that predominantly affects children aged 4-12 months, sometimes affects older children, and rarely affects adults. HUS follows an upper respiratory tract infection.

In the tropics, epidemics of HUS are frequent and resemble an infectious disease; however, no causative organism has been identified. In North America, Shigella-like toxins (secreted by Escherichia coli serotype 0157:H7 or Shigella dysenteriae serotype I) cause many cases of HUS. Diarrhea and abdominal cramps are very prominent symptoms. [12]
