My Niece Just Had A Kidney Transplant And She Just

My niece just had a kidney transplant and she just learned she has atypical HUS. This was found in a biopsy because her new kidney isn't working and is inflamed. What are the chances Solaris will be successful in helping keep the kidney from dying? She is 26 and was diagnosed with Wegeners when she was 12. She has been on dialysis at home for about 18 months this.
