Complications of CIDP can be fatal?

Oh my, this is tragic. My sympathies to his friends and family.

If the cause of death was sepsis caused by infection of his IV line (and perhaps immunosuppression caused by steriods and other CIDP treatments?) could this be considered a case of CIDP shortening lifespan, if not actually causing death?

My neuros at Johns Hopkins are always upbeat and like to say that CIDP is only chronic and that even in progressive cases, the rate of progression can be slowed by treatment, which I have found to be true in my case. However, I think it is wise to recognize that treatments for CIDP, if not CIDP itself, can, in rare cases, contribute to fatal complications, and plan (maintain life insurance, if possible, and other financial and other planning) accordingly.

Perhaps someone has good data showing that fatalities from complications from CIDP are very rate indeed?
