My son was 18 months when he had HUS. He had vomiting and diahrea [diarrhea] for a few days.I took him to his pediatrition,who immediately hospitalized him.The quik diagnosis was nephritis and tests were done to confirm that.In the meantime he developed small black and blue marks all over his body.I called his pediatritian from the hospital room and told him about it.Within minutes the DR. was there and diagnosed him with HUS.He was air ambulanced to the university of Minnesota.He recieved many mnay blood transfusions and other treatment.His kidneys were in distress along with other organs.He had high blood pressure He teetered back and forth from near death.We were there for over a month.He is now 31 years old and full of spunk and energy.It was a tough road that year..but it all had a terrific .happy ending.The Doctors were all fantastic and I call them Jamie’s guardian angels.They pulled him through and I will forever be grateful.a few years later,my 12 year old nephew suffered from the same disease.The doctors at that time believed that our family was predisposed to HUS.So our whole family was warned to very careful to Ecoli exposure.The only residual effect,long term,I believe,was Hyperactivity.I noticed a change in personality after we got home.To this day,he has attention deficit and hyperactivity.
