I have been somewhat remiss in my participation in our community, but here is my personal experience with long-term or cumulative effects of repeated leaks. While I believe I started having leaks prior to July 6, 2010, this was the first and most severe episode that put me in the ICU with compartment syndrome in both legs, failing kidneys and heart irregularities. I received a fasciotomy in my right leg, went through several months of physical therapy and have sustained permanent nerve damage in both feet, although not so severe as to impose major limitations on my mobility. All my other symptoms from that experience resolved once the episode was over.
Between that first episode and my final episode, I had 5 or 6 hospital stays, one of which included a return to the ICU, and numerous minor episodes that I managed at home with lots of hydration. Toward the end of my last hospital stay in August, I was having episodes every 4-5 days, a permanent cycle of hemoconcentration that would resolve and then start all over again despite taking Theophylline and Terbutaline.
Almost thirteen months to the day -- August 5 and 6 of 2011, I received my first IVIG treatment thanks to Arturo's generous kindness and have not experienced any leaks since then. In fact, I feel better than I ever have...but there is one health issue that has come up that may be related in some way, although this is purely speculative on my part and in no way scientific.
I have developed dupuytren's contracture in both hands (I never had much of any swelling of my arms or hands during episodes). It is generally thought to be an inherited condition, but it can be worsened by hypoxia and chronic ischemia (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1743313/pdf/v081p00425.pdf).
This discussion of ischemia's involvement in others who share this disease has strengthened my suspicion that my SCLS may have caused the contracture to worsen as a result of the repeated episodes.
Otherwise, the good news is that with IVIG treatment, my life has returned to normal and other than the few lingering issues I've mentioned, I am healthy again.
