UK residents survey : Prof Shephard/MEBO (until 31/1/21) click to visit survey
click to Read more/less

Prof Elizabeth Shephard is conducting a TMAU fact-finding survey for UK RESIDENTS. She plans to use it to raise awareness with decision-makers, such as perhaps MPs. It closes 31 Jan 21.

who is the survey intended for ?
UK residents who identify with TMAU

Living with TMAU study

We invite you to participate in a research project entitled ‘Living with TMAU’.

click to visit survey

survey full url :
https://meboresearch.co.uk/index.php/living-with-tmau-lwtmau-study/

Participation in the project will involve completion of a short questionnaire, which aims to capture the experiences of those living with the condition. There are two questionnaires.

For individuals with TMAU over the age of 18

For a parent or guardian of a child with TMAU.

The results from the questionnaires will be compiled to produce a report that will be available for you to use, for example, to lobby your MP. The findings will be used to reach out to policy makers in the UK to have TMAU recognised as an invisible disability and to make people aware of what it is like to live with the disorder. The report will be made available on the MEBO, UK website.

To complete either questionnaire you must be over 18 and resident in the UK. The questionnaire responses are anonymous and no personal identifiers will be collected.

The questionnaire closes 11:59 pm (GMT) Sunday 31st January 2021.

MEBO Metabolic Malodor Survey (international) for Dr Hazen click here

survey for ANYONE who identifies with METABOLIC MALODOR

begun : Oct20
end : no ending for now

Regular readers will know that Dr Stan Hazen et al at Cleveland Clinic are developing a TMA-blocker pill, as they proposed in a 2011 paper that TMAO is a factor in CVD. Recently Dr Hazen and colleagues contacted MEBO as they have always thought they could also help with TMAU. This survey is to give them an idea of the 'state of the community'. It is a "version 1". They may not even look (though they have access permission), but it could be useful to give them an overview of the community

MEBO had a zoom call with Dr Hazen and his team in October. Another zoom call is planned when they have time

This is a GOOGLE FORMS survey

1989 Trimethylaminuria Pubmed paper: the detection of carriers using a trimethylamine load test.

1989: http://www.ncbi.nlm.nih.gov/pubmed/2501587
A method potentially of value for investigating putative heterozygotes or carriers of trimethylaminuria by using a single oral dose of trimethylamine (TMA) is described.

This paper from nearly 20 years ago involves 2 well known British experts; Mitchell and Smith. They devised a TMAU test for 'carriers', and what they describe as 'putative heterozygotes'. They are making the carrier urine test a straight 'trimethylamine' challenge test, using TMA at doses of 300mg (for suspected classic TMAU cases), 600mg (they set this as the carrier test), and 900mg (they expect most people to fail this amount).

They found that carriers were around the 77.3% mark with a 600mg TMA capsule, and set this as the phenotype 'carrier' test (this was before the DNA test).


If someone fails the choline-challenge urine test but still suspects they have TMAU, an option could be to try the TMA-capsule carrier test, since this is a straight test of how the enzyme copes with a pure TMA load. The choline test relies on the bacteria to produce the TMA. This would only seem worth considering if not enough TMA/TMAO was produced in a choline challenge test, since if there was enough TMA/TMAO present in the urine, the enzyme got a good 'workout'.

A method potentially of value for investigating putative heterozygotes or carriers of trimethylaminuria by using a single oral dose of trimethylamine (TMA) is described. For healthy volunteers under normal dietary condition and following oral challenge with 300 mg and 600 mg TMA-base, over 90% of the urinary TMA was excreted in the form of TMA (93.6 +/- 1.6%). However, at a dose level of 900 mg TMA-base, there was clear evidence of saturation of the N-oxidation reaction as urinary TMA excretion declined to 77.2% (range 74.8-78.9) of the total dose of TMA...
