Hi Wendy! I'm so sorry to hear that Nolan had another serious episode, and I hope that his kidneys, limbs and everything else came out OK.
As to your question, Korean doctors published an article 2 years ago on their use of pentastarch to treat 2 patients during acute attacks of SCLS. You will find their abstract in PubMed, at http://www.ncbi.nlm.nih.gov/pubmed/17616032. If you want the actual article and cannot download it, let me know and I'll send it to you.
I asked NIH's Dr. Druey about the use of pentastarch and this is what he said: "Pentastarch is an albumin substitute that is a bigger protein and therefore would be predicted to stay in the circulation longer. However, I don’t think it is thought to correct the underlying disorder, but it might be useful to consider it for treatment of an acute episode, as Wendy mentioned."
Hey, you never know!
