Microbiome Symptom Cascade

I just pushed a new page. The model is simple: as the microbiome changes, these changes may cause new symptoms to appear. I have personally seen this cascade in people around me. This page uses symptoms sets entered by users to give rough estimates of what may be occurring next. In some cases, seeing the future may encourage pre-emptive actions today.

https://www.microbiomeprescription.com/Explorer/SymptomCascade

The process is simple, pick an initial symptom in the drop down.

For the symptoms below, just click the one that you have also. This will build up a list symptoms and a qualified list of predictions.

You can change any selected items… in some cases, it may result in nothing being shown.

You can reset to the top one only, or modify what is shown (more or less)

Click Reset to return to just one symptom.

Digging down to the bacteria pattern

As you build up a collection of symptoms, you can quickly determine if there is a bacteria pattern associated. There is nothing gained from adding a 100% item to it…. it means that everyone is the subset has those symptoms so it is redundant. You want to add items that are less then 100%, ideally a symptom you have with the lowest probability.

This transfers your selection across to the page that does statistical analysis on the associated bacteria, as shown below

Accuracy of Prediction depends on YOUR Symptoms being added!

I know there is a “bias” in the data because we do not have an ideal population of samples and symptoms to work from. This page uses what we have, I believe the prediction is better than what a typical medical professional would suggest.

It can be made better by people adding more microbiomes and associated symptoms to the database. This is Citizen Science.

The problem with “normal ranges” from Labs

I have a M.Sc. in Statistics and roll my eyes with the ranges being given by most commercial labs. I know precisely the process that most are rote-following:

To set the normal range, take samples from a group of people with no known issues. Compute their average and standard deviation. Abnormally low is average – 1.95 standard deviations and abnormally high is average plus 1.95 standard deviations.

Other approaches use just 40 people with the values of the 2.5%ile and 97.5%ile being used. Unfortunately, with 40 people that becomes the lowest value and the highest value. At both ends, that is a volatile number šŸ™

My goal with MicrobiomePrescription is to show the numbers from over a thousand samples and let people determine if the numbers are actually unusual by visual inspection.

What should be seen is illustrated below. The average line should be close to the 50%ile with this large of a sample. Two views are usually best.

The log view will give a straight line usually. Where it is not straight, we may have a problem. In this case, below 10%ile is suspect, below 5% is suspect. Over 92%ile is also suspect.
Looking at actual numbers or percentage, gives you better numbers. A typical range is from 35% to 72%

Atypical Bacteria

This bacteria is only reported by one lab, Thryve Inside. If is actually is a sibling to Bifidobacteria genus, both are children of Bifidobacteriaceae.

For another bacteria, we have the average a long distance from the 50%ile and we see what looks like three patterns — each with their own straight line (and not one like above). To get the true 50%ile (including those with zero count) it’s (50+38.2)/(100+38.32 [for Zeros]) = 63%ile on the chart.

The apparent area of concern is the 50%ile above, and issue may be 60%ile
Translating to percentage, Over 0.3% may indicate atypical amounts.

Is it bad to be atypical? If there is not a medical condition or illness associated with it, then likely not. Variety is the spice of life, and the reality of the microbiome.

Some Extreme Examples

For this bacteria, having the average or higher is suspect, factoring in the zeros, we have the average actually being the (82+40)/(100+40) = 87%ile. Visually you can see that things are not looking good.

Bottom Line

Bacteria have a wide variety of growth patterns. Without inspect of the distributions and related information, you may either assume that there is no problem (because the lab ranges are poor — a false positive), or there is a problem when you may have 40% of people have less or more than you (– a false negative).

Do not expect labs to look at the distributions — they only have time to print the numbers and give a canned interpretation. For the microbiome, a canned interpretation is dangerous because of the impact of diet can have. I have oatmeal for breakfast every day, dark 100% rye sandwich for lunch, indian food with chicken for supper. I am pretty much wheat free… and that absence will shift my microbiome greatly.

You have to look at them yourself. You can look up most bacteria reported by labs at this URL: https://microbiomeprescription.com/Library/Lookup

Drill down into Irritable Bowel Syndrome

I am reasonably complete in updating the database. If you know of any substances not shown below that have published peer review studies (a.k.a. PubMed) please email me with links so I may update it.

IBS is often concurrent with ME/CFS and FM.

The drill down page requires you to login. Which means nothing more than going to the login page, enter your email and wait for a login link to arrive in your email. The page is below for those who do not wish to login … my comments continue below it in “Review”

Review

For citizen science looking at probiotics, we actually have a short list and a longer one from PubMed. Lactobacillus GG showed up on both, and on the actual studies list. Clostridium butyricum (probiotics) also has a match from PubMed bacteria to Actual Studies. Different oligosaccharides were on the take and avoid list. Unfortunately, most studies on IBS did not test differences (i.e. tested the forest and not the tree species).

From PubMed

On the avoid list was inulin and it’s associated jerusalem artichoke. Recommending that is a “pro-forma” suggestions from many physicians. So what gives? For that one I did find a study. The study results suggested that you should avoid it — a nice agreement.

 However, flatulence severity was improved by prebiotics at doses ā‰¤6 g/d (SMD: -0.35; 95% CI: -0.71, 0.00; P = 0.05) and by non-inulin-type fructan prebiotics (SMD: -0.34; 95% CI: -0.66, -0.01; P = 0.04), while inulin-type fructans worsened flatulence (SMD: 0.85; 95% CI: 0.23, 1.47; P = 0.007).

Fibromyalgia lacks strong microbiome profile

I’ve just added Fibromyalgia to the website’s Special Summaries. Both published studies and citizen science fail to find any strong patterns. Today (remember the site is constantly being updated with new studies), we see the following summary. Obtaining only two bacteria from citizen science seems to make a strong statement that while the microbiome may be a contributing factor, it is unlikely to be causal.

I tend to favor the root cause being tissue hypoxia with the tissue generating pain from a lack of oxygen.

There may be multiple causes. One possible is coagulation products. Items like serrapetase, nattokinase and lumbrokinase may help. I could not locate any studies using these for FM.

filgotinib for ME/CFS and RA

A reader asked about this. It is a new drug waiting for approval in the EU. On a Spanish group, it is asserted that:

“This is very encouraging news for patients with ME/CFS, as this drug could show very promising results in this ailment. Specifically, this drug decreases levels of inflammatory cytokines, which are believed to be the main cause of symptoms.”

Unfortunately, there have not been a single study for ME/CFS and this statement is very speculative (in my days, I have seen literally dozens of similar claims which consistently under-delivered or caused additional problems). Wikipedia gives a good summary of what it is and its issues.

The most applicable study is shown below.

Bottom Line

Treatments for Rheumatoid Arthritis have often been tried and used for a subset of ME/CFS. Results were generally mixed. The goal should not be “decreases levels of inflammatory cytokines” but stopping the source of inflammatory cytokines. I believe the dominant source of inflammatory cytokines is a microbiome dysfunction.
