ME/CFS Improving Iron Levels by Probiotics

Low iron levels is a common symptoms for ME/CFS. I recently came across a study on how to improve it with the use specific probiotics.

Bottom Line

Probiotics can increase or decrease iron. Our knowledge is limited. If increasing iron is critical then avoid any probiotic containing L.acidophilus. Make sure that you are taking L. plantarum 299v and L. casei

Moderation of COVID-19

There has been a flood of suggestions over the last year for COVID-19. In general, the suggestions are believers in some cure-all supplements, preaching their gospels. The more responsible one register trials and start (example).

The following are what has studies supporting some speculations.

If you know of any other solid studies, please email or add as a comment.

Acid Reflux/GERD – what is known

A reader asked me about this and I have not had to deal with it but I know it is common. Acid Reflux is also called gastroesophageal reflux disease (GERD). So I am doing a summary of my gold standard sources (a.k.a. PubMed). Internet legends are abundant; I know from prior posts that often they got established from some early study that did not replicate, or was even misread… and the legend just kept going on and on by being repeated. You may also wish to review my 2016 post on this topic

As a statistician, I found the following informative in terms of risk factors (hint: changing some of these habits may improve things.

  • non-Hindu religion (2.4% vs. 1.2% for Hindu) [2021]
  • non-vegetarian diet (15.5% vs. 4.2%) – which explains above nicely [2021]
  • lower socioeconomic class ( 31.5% vs. 20.9%) [2021]
  • carbonated soft drinks ( 72.5% vs. 49.8%),[2021]
  • For US women [2021] “The five factors include normal weight, never smoking, moderate-to-vigorous physical activity for at least 30 minutes daily, restricting coffee, tea and sodas to two cups daily, and a “prudent” diet”
  • “we identified 7 risk factors: overweight/obesity [GERD/erosive esophagitis (EE)/GERD symptom], central adiposity [EE], smoking [GERD], alcohol [GERD/EE/non-erosive reflux disease (NERD)], NSAID [GERD], coffee [EE], Helicobacter pylori eradication [EE], and 1 protective factor: physical activity [GERD], ” [2020]
  • “psychological distress were found to be risk factors for esophageal symptoms on multivariate analysis.” [2020]
  • Rotating night shift work is associated with an increased risk of gastroesophageal reflux disease (GERD) symptoms among workers in China: a cross-sectional study [2020]
  • “GERD is common throughout the world, and its epidemiology is linked to the Western lifestyle, obesity, and the demise of Helicobacter pylori.” [2020]
  • ” The represented logistic regression shows that family history of GERD, marital status (divorce), smoking, physical activity frequency, tomatoes/tomato-based foods, salty foods, acidic drinks, frequent use of analgesics, and nonsteroidal anti-inflammatory drugs (NSAIDs) consumption shows statistical significance and association (P < 0.05) with increased risk of symptomatic GERD.” [2020]
    • GERD takes NSAIDs more than controls
    • GERD eats chocolate less than controls
    • GERD eats Tomatoes/Tomato-based food more than controls
    • GERD drinks more citric drinks than controls
    • GERD drinks more tea than controls
    • GERD drinks less pop than controls
    • GERD smokes more than controls (note: smoking is often associated to stress)
  • Short Meal-to-Bed Time Is a Predominant Risk Factor of Gastroesophageal Reflux Disease in Pregnancy [2020]
  • “Sixty-one per cent of students who had a habit of midnight snack for more than three times a week were having GORD symptoms, in comparison to 47% of who did not have the habit.” [2020]
  • Sixty-one per cent of students who had frequent lack of breakfast for more than three times a week were having GORD symptoms, in comparison to 43% of who did not have the habit”[2020]
  • Sixty-three per cent of students who had inadequate sleep were having GORD symptoms, in comparison to 45% of who had an adequate sleep.[2020]
  • ” High BMI, family history, energy drinks and fried food were found to be statistically significant risk factors (p<0.05) by univariate analysis.” [2019]

Microbiome changes of the month (which acts as a reserve to bacteria in gastroesophageal) have been seen

Salivary microbiome with gastroesophageal reflux disease and treatment [2021]

Additional information on microbiome shifts can be found here:

Probiotics

  • “Most gastrointestinal benefits of probiotics have targeted the lower digestive tract, and limited data regarding the upper digestive tract have been reported, particularly for GERD….The aim of this systematic review was to examine the efficacy of probiotics in alleviating the symptoms, incidence, and severity of GERD in the general adult population, as this has not been done before.” [2020]
    • compared with the placebo, postprandial distress syndrome scores declined significantly with the L. gasseri LG21 intervention (37.5% vs. 17.8%)….the underlying mechanisms of L. gasseri LG21 for improving FD-associated reflux are linked to postprandial effects, involving improved protein indigestion and increased gastric emptying.

Hydrochloric acid (HCL)/betaine/pepsin

This is often suggested on blogging and personal opinion sites. I was unable to find any study supporting it’s use and some studies indicating that with some sub-types, it may make it worst.

  • Nutritional Interventions for Gastroesophageal Reflux, Irritable Bowel Syndrome, and Hypochlorhydria: A Case Report, 2016 – mentioned for Hypochlorhydria but not for GERD and this was a single person report.
  • “Decreased acid sensitivity in individuals with increasing body mass index may play a pathological role in symptomatic modulation of patients with GERD.” [2019]
  • “This study shows that a carbohydrate-free diet and/or highly hypoglycidal diet that is enriched with acid pH foods appears to lead to a decrease in the pH of the gastric contents, thus inhibiting the further production of hydrochloric acid with a reduction or disappearance of heartburn symptoms that are typical of gastroesophageal diseases.” [2018] So less HCL results in an improvement.

Herbs / Bitters / Herbal Tonics

While effectiveness is cited in two studies, only a kampo herbal medicine is explicitly named. It may be worth while to try different traditional digestive bitters (as opposed recently created ones)

Bottom Line

As stated above GERD tend to be a western diet disease (and that has been proposed also for the incidence of autism). In terms of life style, the following suggestions should be considered (all of these items appear to be associated to why GERD developed):

  • Early supper
  • No evening snacks
  • Decrease fat and meat content in the diet
  • No soft drinks, citric drinks or tomato based diet (sorry Pizza lovers!)
  • Increase chocolate – ideally 70% cacao or more
  • Daily exercise for 30 minutes
  • No coffee or tea with caffeine
  • Work on sleep — melatonin may help with this, and also the microbiome
  • Lactobacillus gasseri probiotics
  • REDUCE STRESS in your life — yes, it CAN be done. Stress is a state of mind (move on!).

Thus the whys…

  • Not having your digestive tract EMPTY by bedtime (think of circadian rhythm for digestive system being off)
    • Late suppers
    • Evening snacks
  • High fat and meat content in the diet (takes longer to digest — see above)
  • Soft drinks, caffeine(tea, coffee) citric drinks or tomato based diet (sorry Pizza lovers!) – alters bacteria
  • A lack of exercise (impacts microbiome)
  • Stress (impacts microbiome)
  • Sleep issue
  • Not having a good breakfast (think of circadian rhythm for digestive system being off)

On a bit of a speculative nature, given that the mouth microbiome may be a significant player, altering it may be beneficial. There are three items that I would look at:

There is one other approach worth considering, xylitol gum. There is evidence in a recent 2020 study that xylitol helps, Effectiveness of salivary stimulation using xylitol-malic acid tablets as coadjuvant treatment in patients with gastro-oesophageal reflux disease: early findings [2020]

Special Note for Autism

I have seen several children (and the literature agrees) with (very) high Bifidobacterium level, typically without an identified species. We not that there are both increases and decreases in Bifidobacteriaceae shown below. PPI should be use with caution.

acidreflux
This BMJ article had a nice graphic of what PPI’s do with red dots indictes higher growth and blue dot with decrease. 

Salicylate Sensitivity – What do we know

I have done a recent review of a child with salicylate sensitivity and in dialog with the parent, I realized that I need to get up to speed on this topic. One of the reasons is that we found that some of the recommendations were matches to some studies for salicylate sensitivity. So far the citizen science analysis at microbiome prescription has not found any specific bacteria associated (not sufficient samples). If you have uploaded a sample AND have salicylate sensitivity, please make sure you have updated you symptoms.

There are many web-sites/blog dealing with salicylates — which given the absence of actual studies, may be worth reading. As always, I will attempt to keep to “gold standard” data sources.

Salicylate poisoning can cause vomiting, tinnitus, confusion, hyperthermia, respiratory alkalosis, metabolic acidosis, and multiple organ failure. Diagnosis is clinical, supplemented by measurement of the anion gap, arterial blood gases, and serum salicylate levels. Treatment is with activated charcoal and alkaline diuresis or hemodialysis.

Merck ASPIRIN AND OTHER SALICYLATE POISONING
  • “Alkalinisation, the mainstay of therapy for salicylate and phenobarbital poisoning over many decades, is effective, although no more so than charcoal, and less than dialysis” [1990]
  • “Forty-four adults with aspirin poisoning were treated with oral fluids only, standard forced alkaline diuresis, forced diuresis alone, or sodium bicarbonate (alkali) alone. Alkali alone was at least as effective and possibly more effective than forced alkaline diuresis in enhancing salicylate removal. ” [1982]
  • “One of the more popular and successful treatments has been forced alkaline diuresis to encourage excretion. This technique, however, is not without risk and has now been replaced with alkalinisation alone, which has been shown to be safer and equally successful. The use of activated charcoal as an acute absorbing agent for drug still in the upper gastrointestinal tract is beneficial in minimising further absorption. ” [1992]
  • “When the urine pH increases to 8 from 5, renal clearance of salicylate increases 10-20 times. Raising the urinary pH level from 6.1 to 8.1 results in a more than 18-fold increase in renal clearance by preventing nonionic tubular back-diffusion, which decreases the half-life of salicylates from 20-24 hours to less than 8 hours. ” [MedScape]

Treatment of severe salicylate poisoning by forced alkaline diuresis. [1969]

The concept of an alkaline diet is popular.

CFS/ME and COVID Vaccines

A reader ask me to do a post on the COVID vaccines and people with Chronic Fatigue Syndrome / Myalgic Encephalomyelitis. The risk of death is a significant factor in making a personal decision. This is different than most vaccinations; we need to look afresh at this decision and not run off pro forma decisions for things like measles or extremely low risk-of-infection diseases (polio)

  • Measles risk of death 2 in 10,000 or 0.02%
  • For flu: [cdc]
    • 18-49: 0.02%
    • 50-64: 0.05%
    • 65+: 0.85%

There are possible side-effects, which appear to be transitory for typical people.

 A review of unblinded reactogenicity data from the final analysis which consisted of a randomized subset of at least 8,000 participants 18 years and older in the phase 2/3 study demonstrates that the vaccine was well tolerated, with most solicited adverse events resolving shortly after vaccination. The only Grade 3 (severe) solicited adverse events greater than or equal to 2% in frequency after the first or second dose was fatigue at 3.8% and headache at 2.0% following dose 2. Consistent with earlier shared results, older adults tended to report fewer and milder solicited adverse events following vaccination

PFIZER AND BIONTECH CONCLUDE PHASE 3 STUDY OF COVID-19 VACCINE CANDIDATE, MEETING ALL PRIMARY EFFICACY ENDPOINTS 18 Nov, 2020

I did a prior post on POTS as a consequence of vaccination. Fortunately, that is moot since most people with ME/CFS already have POTS! It is important to note that positive benefit can happen with some vaccines: Effects of  vaccine on pain and fatigue in patients with fibromyalgia/chronic fatigue syndrome.[1998] that “Fifty percent [of ME/CFS] were rehabilitated successfully and resumed half-time or full-time work.”

There is concern on aluminum in vaccines and ME/CFS as documented in this 2016 post. With subsequest studies

More Recent Studies

Which Vaccine has Aluminum?

For people in the US, we have a list of all vaccines and their ingredients here. You will see Human Papillomavirus (HPV) (Gardasil 9) cite above, contains amorphous aluminum hydroxyphosphate sulfate.

Bottom Line

The key issue is whether there is aluminum in the vaccine. If there is, it may worsen existing symptoms (especially neurological issues). The bad news is that appears that the current COVID-19 vaccines some contains aluminum (alum) and others do not.

So the traditional and documented issue with vaccines (the aluminum in it) does not apply to two of the Covid vaccines. This implies that for FM, CFS/ME, there is not a supportable evidence-based reason to decline it.

For all ages, the risk of death is significantly higher than for the flu: [see cdc numbers above]

  • 18-49: 0.02% vs 0.1 to 0.4% i.e. 20x greater risk
  • 50-64: 0.05% vs 0.5 to 3.6% i.e. 72x greater risk
  • 65+: 0.85% vs 6.3% to 20%, i.e. 24x greater risk
Covid cfr by age
From https://ourworldindata.org/mortality-risk-covid

The side effect risks are low and appear to be transient. “Long Covid” – the name given to a CFS-like syndrome after a COVID infection is likely to make any existing ME/CFS or FM much worst. This is estimated that 10% of people are prone. The probable model is that long covid has resulted in a stable gut bacteria dysfunction (for a similar documented-over-several-years similar scenario see this post)

One study of people hospitalized with COVID-19 in Italy found that 87.4% reported experiencing at least one symptom, often fatigue or shortness of breath, 2 months after discharge. Among people with milder infections, however, the prevalence of long COVID has been unclear. Data from the COVID Symptom Study app suggest that 1 in 10 people with the illness experience symptoms for 3 weeks or more

COVID-19 Symptoms: Longitudinal Evolution and Persistence in Outpatient Setting [2020]

Get the vaccine — there is no evidence-based reason not to (especially if there is no aluminum in it). Not taking the vaccine means significant risk of death and likely more severe CFS/ME or FM.

Post Script – I had COVID… Should I get the vaccine?

Answer is a simple yes. Protection with the vaccine is expected to last longer… Think of it as a booster shot!
