Purpura is a symptom of hemolytic uremic syndrome, which affects both the blood and the kidneys, explains MedicineNet. When the kidneys cannot filter the blood, waste products such as urea build up in the bloodstream and cause illness. At the same time, blood clots abnormally in the patient's capillaries. This causes the purpura. HUS is caused by food poisoning and other conditions.

Uremic pruritus is common among people with kidney disease and is considered an inflammatory disorder rather than simply itchy skin, states Dr. Kuypers. It causes bouts of torturous itching. The itching is usually worse on the patient's back, head, arms, legs and chest, though some patients itch all over. Heat and stress make the itching worse, but it can be eased by showers. Because the itching tends to be worse at night, it interferes with the patient's sleep and badly affects quality of life. Kyrle disease is a skin condition that results in persistent, scarring lesions on the skin. It can cause and be the result of scratching from uremic pruritus.
