From this article I can tell that they do not really know much about the disease, how we got it and much less how to treat it. At least they know that people with IBD have a lot of bad bacteria, like E-Coli and not enough good bacteia. So, just from this info why would they use immunosuppressant drugs to treat UC or Crohn's? Basically they are saying that our immune system is weak, compromised and can not fight the bad bacteria and they give us immunosuppresants. No wonder so many people end up with C-diff.
Right here is an example of misunderstanding, mistatement, and poor logic. The summary quoted said that the immune system was "overly aggressive" due to too few regulator cells and too many attack cells. How by any dictionary does aggressive=weak? Where did it actually say the immune system could not fight the bad bacteria? It cannot seem to vanquish them, but it is very likely that the aggressiveness has heightened specifically to battle the bad bacteria that run rampant in UC. I do not think the immune system was ever intended to control the bad bacteria on its own, so its failure to control them (without any help) does not mean it is "compromised". The good bacteria are known to play several important roles in down-regulating the bad bacteria.
Interesting questions are did the imbalance alter the immune system into an aggressive posture? (In which case the genetic predisposition is a vulnerability to being altered.) Or, was the immune system always more aggressively positioned, and the imbalance kind of turns up the volume to the point where it is a problem (i.e., autoimmune). (In this cast the genetic predisposition would have been in the innate balance of immune system cells.) It is likely that finding a cure will depend on the answer to those questions.
Other questions might focus on the gut flora imbalance. Did some innate (i.e., genetically coded and perinatally expressed) aggressive balance of regulator and attack cells in any way contribute to the development of the imbalance. (In many cases something like massive antibiotics might have most directly caused the imbalance, but something about
the individual's immune system could also contribute.) Did the disproportionate number of attack cells in the immune system somehow prevent the re-establishment of the good bacteria? (If so, it is possible balance would only be restored if the immune system was suppressed for a while.) When considering the immune system imbalance and the gut flora imbalance, we end up asking the chicken-egg question, "Did the flora imbalance or the aggressive attack posture come first?"
Then there are questions of reversibility. If gut flora balance is restored will the auto-immune response subside, or just the symptoms? If probiotic therapy does not help, does it mean that the good bacteria did not get to the colon? Or does it mean they got there but were unable to colonize?
Anyway, when you find yourself asking a question along the lines of "Why aren't medical practitioners doing the obvious?", it is a good time to pause and look for where you might have confused "aggressive" with "weak", or more generally, have relied on an incorrect or overly simplistic premise. Chances are it will lead to increased insight and understanding.
