My son was diagnosed with CAPS resulting in kidney failure in 2009 at age 17. He was on Lovanox for 2 years/now Warfarin. He was on dialysis for 10 months waiting a kidney transplant. Beings we live in a rural area, & sometimes get snowed in, my son asked his doctors if he could do a test to see how long he could go without dialysis. Christmas Eve 2009 he stopped dialysis, never to return to it. His kidneys are functioning at 51%. The only meds he takes are a low dose of blood pressure medicine and Warfarin. Along with some Vitamins he has chosen. He now has a new hemotologist who says that his tests show he is now negative for the antiphospholipid antibody & thinks he could stop taking Warfarin...I'm very uncomfortable with this...what do you think?
