The lesions will eventually be covered by eschar - dead black leathery skin. Most of the doctors wanted to remove the eschar. The wound care center did not - called it a biological bandage which protected the wounds. We also kept these covered. Eventually they broke away along the edges - due to new skin pushing the edges out. At this point we started using gentamycin ointment and packed the edges. Four years later, the last of the lesions healed.
Kennube, I could write at length but I won't. Please feel free to pm us and I will share all that we know and all that we experienced. How large are your sister-in-law's lesions? The greater the surface area, the greater the risk.
Other comments:A. While lesion formation is ongoing, there is a treatment: Sodium Thiosulfate. It was not available in 2003, when Rolando's bout began, but I understand that it was standard treatment in Britain a year ago.
B. Calciphylaxis, though still rare, is becoming more common. It has been suggested that it may be because of the use of Vitamin D analogs in the dialysis population. Rolando had just been started on Zemplar when the pain which precedes the lesions began to occur. Your sister-in-law is post transplant so I am not up on whether or not such drugs are used, but if so, get her off of the Vitamin D analogs and if binders are still used, get her off of any which might contain calcium (such as Phoslo).
Again, though, the cause of calciphylaxis is unknown.
C. Consider hyperbaric oxygen for wound healing. Do the research - I don't remember a positive correlation between hyperbaric oxygen and wound healing, but it can't hurt. (My strongly held opinion is that time is necessary for healing these wounds because time allows the body to revascularize the areas.)
D. No one would provide us with sufficient wound care supplies. We always had to supplement ourselves. Surf the net. There are sources of bulk supplies - bandage rolls, gauze sponges, sterile saline, etc.
E. Ease her pain! Calciphylaxis is immensely painful. It is tissue death - the same pain as a heart attack. Make sure she has a doctor who is as aggressive as necessary with the pain meds.
