This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Calciphylaxis is a rare and serious condition that causes painful, open skin wounds in people with end-stage kidney disease who need dialysis. This trial is testing whether rheopheresis—a procedure that filters your blood to remove harmful substances—can help heal these wounds better than standard care alone. Some participants will receive rheopheresis plus their normal care, while others will receive a sham (fake) procedure plus their normal care, so doctors can see if the real treatment makes a difference.
Calciphylaxis causes severe skin damage and is hard to treat with standard care alone. Researchers believe that filtering out certain inflammatory substances from the blood may reduce the damage, but this hasn't been proven yet in a large, rigorous study.

If you join this trial, you'll receive either rheopheresis or a sham procedure in addition to your regular dialysis care. The treatment starts with an intensive phase: three filtering sessions during the first week, then two sessions per week for the next three weeks. After that, you'll have one session per week for about two more months. Each session takes a few hours, similar to a dialysis appointment. Your medical team will monitor your skin wounds and overall health throughout the study to see if the treatment helps heal your wounds.
