The other method would potentially be of benefit to all sufferers. It has long been mentioned that if a bacteria/probiotic could detoxify trimethylamine in the gut, then it could do the (gut) detoxifying for the person. The long-speculated suggestion was for a bacteria engineered to be rich in FMO3. Dr Christodoulou is proposing to use a known harmless bacteria (Methylophilus methylotrophus) that, instead, detoxifies trimethylamine by an alternative pathway. Rather than FMO3 (which changes it to trimethylamine-n-oxide, the trimethylamine will be altered to dimethylamine and formaldehyde by an enzyme in the bacteria (trimethylamine dehydrogenase).

However this may be unimportant and we are grateful for any research. It would be interesting to know if this bacteria is available. It is possibly used in the agricultural industry as a source of food for pigs. But nobody likely knows the potential averse reactions in humans. At this stage, we can only wait to see how the mice get on, although these 2 treatment stages aren't planned until year 3.
Other strategies for metabolising TMA in the small intestine:
Anaerobic gut bacteria can contribute to the trimethylamine load in patients with TMAU by enhancing the metabolism of choline in food to trimethylamine in the gut1. As stated above, one form of therapy of TMAU, albeit in more extreme cases, is to treat patients with antibiotics aiming to reduce the intestinal load of these bacteria. However, the antibiotics that need to be used have potentially serious side effects, and so can only be used for short periods of time.An alternative strategy for reducing the gut trimethylamine load would be to colonise the gut with harmless bacteria that are capable of metabolising trimethylamine. One such micro-organism is Methylophilus methylotrophus. This is an aerobic monoflagellate bacterium that uses methanol as the sole source of carbon and energy16. It was initially thought to be of potential commercial value in the single-cell protein production industry, but it proved to be a nonfinancial venture. When cultured in trimethylamine, the enzyme trimethylamine dehydrogenase is induced, which converts trimethylamine to dimethylamine and formaldehyde17. Extensive studies have shown that this micro-organism is non-pathogenic and non-toxic in animals18, 19. Therefore colonisation of the gut with Methylophilus methylotrophus in individuals with TMAU could be of potential therapeutic utility.

Is there a cure then?
Hi
If you mean this,the funding was never raised so it was never tried.
In theory there are probably similar things that could be tried to reduce or metabolise TMA production, although currently it is not known if anyone is trying to do this.
