Lisa Marie's TMAU Story

 

First hand experience with TMAU video, Lisa Marie




This video is a first hand experience with Trimethylaminuria (TMAU). CEO & Founder, Lisa M Marie of Silas Garrison Fisher, Inc, an organization dedicated to bringing about Public Awareness of Rare Medical Disorders, gives her account and experiences with living with this disorder.

Lisa has kindly written her biography for this blog, see below, as we join efforts with her to assist her in her Raising Public Awareness of Rare Medical Disorders. Lisa has reached out to her local university to see if they would offer her pro-bono legal services to become a Charity, but they do not offer this service as Florida International University offered MEBO Research. Therefore, she is struggling to write the required documents and filing them on her own. I hope that MEBO Research and Silas Garrison Fisher, Inc., can join forces from time to time to further our cause.



The Silence Broken by Lisa Marie Marie

This is a first hand account of my life living with TMAU, but TMAU is not my life.


The first known symptoms occurred at the age of approximately (10) ten, when family members and school officials discussed my body odor. I was cared for by my grandmother, where she would use Clorox in my water, and a mixture of baking soda to manage the odor.

As a child school was not easy, suffer bulling and abuse from other children. This abuse ranged from verbal insults to physical, such as having washing powder poured on me after school, or teachers having my classmates to take me to the bathroom to wash me. I was passive and often felt as though my condition was my fault and I somehow deserved the abuse. This was the first of my many moments of depression and embarrassments.

As puberty set, the odor also increased, on many days I missed school. I had only one friend through high school as they also had their condition and we accepted each other just as we were. The odor seem to come and go at the most odd moments, and as I became more aware of the condition, I made it a purpose for me to avoid people. I sought to cling to my spirituality, however, I found people in Church judge you as well as the world did. It was then I realized that I only needed me and God alone to truly have church.

As I began to seek employment, it was either I was qualified for the job, but after meeting me, I was not chosen, or if I was chosen and the disorder was not currently present, that multiple hygiene meetings were called, both public and private meetings. Soap was also left for me, or ugly notes. Traveling to and from work was not easy as I suffered harassment on buses, which ranged from the bus driver making bad remarks, (whereby with I began moving to the back of the bus opening a window) to a passenger spraying perfume around me.

I began to be proactive and try to find out what was wrong with me via the internet. This was slso an issue, as librarians would turn up the air, spray air freshener or open a foor, then gathering and looking back at me. I found two conditions which were bromhidrosis and TMAU.

I began going to a local dermatologist, and after going from doctors, one took the condition seriously and noted the symptoms. I was given Botox injection, medications, which had side effects, such as sensitivity to light, where I had to wear sunglasses. I tried taking 4-5 showers or baths a day, herbal remedies, colon cleansing, perfumes, supplements, changing all my clothing to cotton material, low pH balance soaps, prescription deodorants, herbal soaks, changes in diets, etc, etc…

I made characters that matched each disorder creating Heroes’ out of each one. I wanted to show that although we have this disorder we are all heroes’ and are a special gift to the world with a purpose.
I took a test for TMAU and was diagnosed with the disorder in the 90’s, at the least I had a name. I still continue trying remedies and will never give up. Instead of feeling sorry for myself I began creating an organization (Silas Garrison Fisher) concerning this and other rare disorders that I had come across in my research. I wanted to make it interesting, and so I made characters that matched each disorder creating Heroes’ out of each one. I wanted to show that although we have this disorder we are all heroes’ and are a special gift to the world with a purpose. In so doing I added information concerning the disorders, a support group for people to gather and talk about there condition or even their day to day experiences, I wanted also to promote healthy eating for others. I currently have promotions on Facebook with giveaways to assist with public awareness.

This is limited, for I am limited in funding. However, I am attempting to raising funds that would pay for testing of TMAU for individuals who have not yet been diagnosed, I feel my condition has a purpose, and this is one of those purposes. It has been going slow, as even advertising on Facebook cost, but I am hopeful.

In losing I now have my children and a special person in my life that I can talk out anything, they have made me stronger, more outspoken. I have educated myself concerning laws and rights that protect me from abuse, and I use them to do so.


P.S. God sent me a Minister and a counselor, just what I needed, as he is a part of my organization providing counseling (licensed).

Rare diseases affects us all, no matter the race, color, creed, and nationality.

Thank you, Lisa for coming forward and being proactive in your efforts to make a difference in the lives of all sufferers. The more sufferers who follow your example and join together, the more we can accomplish!

Korean lab produces a trimethylamine enose for the food industry

From http://www.meboblog.com/2012/08/korean-lab-produces-trimethylamine.html

 

Korean lab produces a trimethylamine enose for the food industry

trimethylamine enose
Korean paper on TMA enose : click to read abstract
A 'bioelectronic' enose that detects trimethylamine (TMA) levels has been constructed by scientists in a lab is Seoul. It is designed to detect fish spoilage in the food industry, but perhaps it could be adapted for people with trimethylaminuria (TMAU).

When fish spoils, the trimethylamine-oxide in the fish is decayed by bacteria into trimethylamine, which gives the odorous rotting fish smell. In TMAU, it is trimethylamine that causes the odor, although perhaps TMAU does not fully explain the range of odors in someone with a FMO3 enzyme issue. However it would seem trimethylamine is an excellent biomarker of FMO3 function if it is being produced in a person's gut.

Apparently the sensor was 'simply manufactured' and is 'portable' so it seems that a small application for humans may be a reality in the future.


Abstract
We herein report a peptide receptor-based bioelectronic nose (PRBN) that can determine the quality of seafood in real-time through measuring the amount of trimethylamine (TMA) generated from spoiled seafood. The PRBN was developed using single walled-carbon nanotube field-effect transistors (SWNT-FETs) functionalized with olfactory receptor-derived peptides (ORPs) which can recognize TMA and it allowed us to sensitively and selectively detect TMA in real-time at concentrations as low as 10fM. Utilizing these properties, we were able to not only determine the quality of three kinds of seafood (oyster, shrimp, and lobster), but were also able to distinguish spoiled seafood from other types of spoiled foods without any pretreatment processes. Especially, the use of small synthetic peptide rather than the whole protein allowed PRBNs to be simply manufactured through a single-step process and to be reused with high reproducibility due to no requirement of lipid bilayers. Furthermore, the PRBN was produced on a portable scale making it effectively useful for the food industry where the on-site measurement of seafood quality is required.

Chemicals in food affecting body odor

Volatile compounds (complex organic and simple like hydrogen sulfide and ammonia), together with sugars and acids, are the main chemicals determining the characteristic aroma of food, as well as odors related to human body.

The bad smells are generally the result of a combination of odorous sulfur compounds and ammonia.

Volatile sulfur compounds are produced through bacterial metabolism of sulfur amino acids such as cysteine and methionine. High sulfur content in food is another source.

Choline  - a quaternary saturated amine - can lead to increases in the amount of trimethylamine responsible for sweet and sickly, fish-like smell.

How to estimate the amount of choline, sulfur and sulfur-containing aminoacids in your food?
You can do it easily with Aurametrix.

Studying body odor: one step at a time

Unpleasant body odors could be a sign of a disease. But even when the cause of the disease is known - an example is trimethylaminuria or TMAU - there are no one-size-fits-all solutions. Elimination of choline and other essential nutrients from diet can be harmful and unhelpful.  Everyone has their own unique needs, with individual combinations of foods, activities and optimal environmental conditions.

An earlier survey of about 100 body odor and halitosis sufferers indicated stress (34%), food (25%) and environment, including the weather and perfumed products (15%) as main triggers of odors. 23% of sufferers did not know what the trigger was.

Our study seems to have less unknowns. As you see from the picture, 60% of participants have both body odor and halitosis. Only 22% of participants were diagnosed with TMAU, one third has IBS, one third has environmental sensitivities (mostly pollen and mold allergies, but some have dust mite and pet allergies and chemical sensitivities). Over 60% of participants reported sensitivities to specific foods. Most frequent was lactose sensitivity.

It is known that a specific diet, infections and diseases have major impact on variations in human body odor.  Some of our early results on fatty and ammonia types of odors identified a few food ingredients and their maldigestion as potential causes. Our next posts on musty and smoky odors, as well as unpleasant odors in general will tell more.

The smell of Christmas

How does Christmas smell like? 

Like cinnamon! So say studies by European scientists  [1-3]. And even though the smell of cinnamon is described as "pungent" (besides "warm", 'sweet", and "spicy"), it fires up our brains, evoking a joyful Christmas mood and making us more generous. 

Cinnamon is classified as a stimulant. Smelling and tasting cinnamon could enhance attention and virtual recognition memory [4], at least in comparison to smells of peppermint, jasmine or cherries. In addition to its many healthy properties - like fighting E.coli in unpasteurized juices, lowering concentration of  fasting glucose, triglycerides, and total cholesterol - Cinnamon can make you feel fuller for longer [5]. So for those of us hoping to lose some weight - a cinnamon-flavored floss would be a good replacement for a Christmas desert.

Aggregate correlations - aka experience of the crowds analyzed in Aurametrix - tell many good things about Cinnamon. For example, that it led to less severe joint pain and helped with bad breath. Although - in higher concentrations - it was the reason of a yellowish skin.

Unfortunately for those with digestive problems, other Christmas-flavored foods seemed to have more side effects. Aurametrix correlations for Apple told that exceeding sensitivity thresholds could lead to gas, fecal and musty smell (was this why an apple a day kept the doctor away?). Too much orange was associated with bloating, indigestion and yellow stool. Pumpkin, on the other hand, lead to slightly better flavored gas!

With more daily observations entered by the users, Aurametrix will make more correlations between wellbeing and food flavors. But for now -

Merry Christmas! And let's smell some cinnamon!

The Road to Ammonia

Why do I smell like Ammonia? This question, in thousands of variations, has been asked over and over again at every major question/answer site, especially teen, bodybuilding and athletic forums.

The Internet provides plenty of opinions.

Medical sites talk about diseases like chronic kidney failure, hepatic cirrhosis or H. pylori infection. Fitness sites recommend drinking more water, reevaluating protein sources and eating more carbohydrates.
What are these diet-odor links? And what's the Science? Ammonia may be formed during the alkaline hydrolysis and deamidation of proteins - by our own metabolism and the metabolism of microbes that call us home. If our kidneys can't handle the load of nitrogen, it's excreted as ammonia in sweat. Excretion increases 10 times as temperature goes from 70 to 100 Fahrenheit.

Aurametrix is a breakthrough analysis tool that correlates users' actions and reactions based on what information they enter into the system. Preliminary correlations in the Aurametrix knowledge base show exactly what's expected: excess protein does lead to ammonia-like odor.

But wait a minute - does it say the same about excess fat?

An  example provided by one of our users is very interesting. The user logged a few foods he thought were contributing to odor. These were different odors according to the user - ranging from "Ammonia-like" to "Fishy", sharp, cloying and stale. Aurametrix, however, recognized that all these odors described by the user may be related to nitrogen-containing compounds.  When these three data points were analyzed along with four foods that the user did not associate with any odors, Aurametrix displayed only one result:

Based on your Aura entries, the following may be contributing to "Ammoniacal odor" in a 3 hour timeframe:

Hexadecanoic acid  - commonly known as Palmitic acid - is one of the most common saturated fatty acids in the Western diet. Palm oil and coconut oil contain especially high levels of this acid. What effect does this acid have on metabolism? It down-regulates glycose metabolism and protein metabolism, affecting Calcium or mRNA binding proteins [1]. So there may very well be a connection!

What's that fatty odor?

Body odor is closely associated with diet. Deciphering the chemistry of human odor is not an easy task - only about 5% of odorous molecules are usually recovered from collection containers, and not all of the molecules are identified in complex spectra. Volatile fatty acids, alcohols, and aromatic ring compounds comprise a substantial fraction of smelly molecules, yet very little is known about the origin and factors controlling their production in humans. Fortunately for some (and not so fortunately for others), the human nose can capture and discriminate many smell signatures. Could this discrimination be used to connect the dots between diet and body odor? MEBO Research has just started an anonymous study using the Aurametrix health analysis tool to find out.

Aurametrix's knowledge base provides a wide selection of foods and symptoms, including different types of odors recognizable by the human nose. Participants in the study have been recording some of their food intake and activities on days when their symptoms are better or worse than average, entering items they suspect might be contributing to or alleviating their body odor on those days. The tool's analysis engine then lets them explore all the possible cause-effect relationships. In addition, Aurametrix performs automated analyses across the entire user community and displays cumulative results as "aggregate correlations." The figure on the right is an excerpt from these results.

Although the study has only just begun, the preliminary results already look very interesting. One example is fatty odor. Aurametrix linked several dietary chemicals to unpleasant "fatty odor" emanating from skin based on Aura entries of several participants. The top chemicals so far are:  Vitamin K1 (phylloquinone), Octadecanoic acid, FODMAPs, Beta-carotene,  Carbohydrates and Monosaccharides. Another interesting result (although there were fewer observations) is that Vitamin B12 obtained from diet seemed to help prevent fatty body odor.
  • Could Vitamin K1 really contribute to "fatty" odor?  Could 6 observations derived from different users' Auras be just a coincidence? Vitamin K is proposed to increase production of alkaline phosphatase in intestines. This enzyme produces a number of different substances, some of which have a peculiar sweetish smell.  Chlorophyll, usually recommended to combat body odor and supposedly makes odor "sweeter," is an excellent source of vitamin K1. And so is Asparagus that gives urine a disagreeable odor.
  • Octadecanoic (Stearic) acid was also linked to fatty odor in 6 observations. This saturated fatty acid is most abundant in animal fats and cocoa butter, and also in nuts and seeds (peanuts, flax), cheese, cookies and candies. Its smell is fairly mild, yet can be detected by the human nose (Bolton and Halpern, 2010). Besides, it slowly converts in the liver to heart-healthy oleic acid which has a faintly fatty odor with a hint of dead insects. It could also metabolize into other compounds and incorporate into liver lipids or follow alternative routes.
  • FODMAPs, highly fermentable but poorly absorbed short-chain carbohydrates and polyols, were found to be an important dietary factor contributing to gastrointestinal symptoms. Perhaps FODMAPs, carbohydrates and monosacharides in particular could also contribute to odor in the absence of GI discomfort?
  • Beta-carotene is another heart-healthy chemical with anticancerous properties important in human nutrition as a source of Vitamin A. Tobacco, tea, many spices and flowers owe their flavors to chemicals metabolized from beta-carotene. One of such chemicals is warm and woody beta-Ionone that smells of blackberry at lower concentrations and fatty-cheesy at higher concentrations.

The chemistry of odors and their origins is undoubtedly very complex. Yet, these preliminary results show that together we may find the answers to many health-related questions. With more participants, we'll soon connect the dots between diet and body odor. Want to participate? Write to:
