I have AS. Diagnosed or rather verified on the sole basis of presence of HLAB27 antigen. Luckily it's peripheral, but it was detected pretty late in the cycle. The doctor was super helpful. I realize the how this is an evolving science when I shared the reports with a friend who studied medicine for 8 years, and her reaction was total surprise about the tests, medicines, and injections I was given. Only thing that has worked so far is Adalipca injections and they too need to be taken atleast once every year (two at a time). (Edit: The doctor told me pointblank that we dont know what could have triggered it)

I read somewhere that a startup was working on controlling Immune system response via some brain waves. I have never rooted so strong for any startup as I am rooting for them.
