I had seen this. As one of two clinical trials with VSL that I found in the literature, I wanted to see what dose they used. I had been doing one DS sachet daily and after some initial benefit it seemed to become less effective.
I think it is important to note that in this study, VSL did not significantly improve remission. The p-value is above .05. But it did significantly reduce some symptoms. An earlier study (I posted about
both of these studies in some thread) did find a significant increase in remission. SO the evidence is positive, but slightly qualified.
BTW, I decided to do 4 DS sachets/day for 8 weeks (just like the studies). The noticeable benefit returned, but after 4 weeks I was not getting any increased benefit and was getting a lot of gas. I tapered back to 1-2 sachets/day without doing the full 8 weeks.
I recently skipped a few days both of the VSL and of my 2x weekly Rowasa, and I started to get a lot of GI rumbling, bloating, gas, and hourly loose stool and diarrhea - even waking a couple of times a night.
My bad.
I went back to 2 DS sachets daily, and temporarily (I hope) increased my Pred from 7.5mg to 20mg. This seems to have nipped things in the bud, and I am seeing improvement each day. Unfortunately, I was not like the patients who got remission. But, I do enjoy having less symptoms.
As for the "probiotics story",
I don't think there is any doubt in the colitis research community that there is dis-regulation of the gut micro-flora with IBD. There is some confusion of whether the autoimmune leads to dysbiosis, or dysbiosis leads to IBD. There is also evidence that whichever comes 1st, the influence goes back and forth over time. Science did a special edition on the Gut Microbiota in the June 8 2010 edition. (

Interactions Between the Microbiota and the Immune System

Abstract
The large numbers of microorganisms that inhabit mammalian body surfaces have a highly coevolved relationship with the immune system. Although many of these microbes carry out functions that are critical for host physiology, they nevertheless pose the threat of breach with ensuing pathologies. The mammalian immune system plays an essential role in maintaining homeostasis with resident microbial communities, thus ensuring that the mutualistic nature of the host-microbial relationship is maintained. At the same time, resident bacteria profoundly shape mammalian immunity. Here, we review advances in our understanding of the interactions between resident microbes and the immune system and the implications of these findings for human health.
