L. sakei

There has been an exciting development in chronic sinusitis research and treatment using the beneficial bacteria Lactobacillus sakei (L. sakei), specifically with the probiotic powder Lanto Sinus. This recent study took a different approach to chronic sinusitis by looking at the immune system.

Researchers conducted a sinusitis study of individuals with chronic sinusitis, all who had undergone multiple sinus surgeries and were considered hard to treat (had continuing problems with sinusitis, thus refractory). The researchers found that using Lanto Sinus (with its specific strain of L. sakei Probio65) had very good results in treating many of the individuals.

Lanto Sinus probiotic powder

The treatments involved using Lanto Sinus (L. sakei proBio65) as a nasal rinse (1/4 teaspoon of Lanto Health powder in 2 tablespoons of normal saline nasal rinse) once a day and 1/4 teaspoon (240 mg) twice a day in food. This continued until they felt healthy. [IMPORTANT: Stop the use of L. sakei when feeling better.]

The researchers approached chronic sinusitis by looking at the immune system, specifically IL-12, a substance involved with immune system functioning. They found that IL-12 levels can be low in chronic sinusitis sufferers. Using L. sakei raises IL-12 levels, which they thought explained the positive results.

In other words, their thoughts are that microbial imbalances in chronic sinusitis could contribute to IL-12 signaling defects, and this results in low IL-12 levels. Which L. sakei can correct. 

How was IL-12 measured in the study? Blood was drawn from each person and a lab analysis was done - called a pSTAT4 phosphorylation assay (which measures immune health related to IL-12).

Next: Now the researchers are starting another study to further look into this. Stay tuned!

Abstract (summary) excerpts from medRxiv (for preprints), and now at National Library of Medicine: STAT4 Phosphorylation of T-helper Cells predicts surgical outcomes in Refractory Chronic Rhinosinusitis

Abstract

Objective: Chronic rhinosinusitis (CRS) impacts an estimated 5% to 15% of people worldwide, incurring significant economic healthcare burden. There is a urgent need for the discovery of predictive biomarkers to improve treatment strategies and outcomes for CRS patients. ...continue reading "Looking at the Immune System in Chronic Sinusitis"

Published on Leave a comment on Fungi and Bacteria In The Sinus Microbiome

The sinus microbiome consists of bacteria, viruses, and fungi all coexisting in the sinuses. Research has long focused on how the bacteria in sinus microbiomes in people with chronic sinusitis is different than in healthy persons without sinusitis (and yes, there are differences). Differences in the mycobiome (the fungi) of the sinuses appear to also play a role in chronic sinusitis.

A few recent studies found that there are differences in the fungi living in the sinuses in those without sinusitis and those with sinusitis (but results varied among the studies). Whether fungi play a role in the development of sinusitis has long been debated. Additionally, when samples are taken with a swab compared to sinus tissue samples during surgery - the results are different.

In a recent study, researchers found differences in both the fungi (mycobiome), as well as bacteria, in persons with chronic sinusitis compared to healthy persons (the controls). There were differences in bacterial diversity (diminished diversity in those with chronic sinusitis), as well as the composition of the microbes. The researchers thought that fungal alterations can play a part in sinusitis.

By the way, when microbes in the sinuses are out of whack it is called dysbiosis. Researchers point out that the same microbes can be commensal or pathogenic (if numbers increase to high numbers) or have no effect on sinusitis.

Excerpts from The Laryngoscope: Fungal and Bacterial Microbiome in Sinus Mucosa of Patients with and without Chronic Rhinosinusitis

Abstract  Objectives - Dysbiosis of the sinonasal microbiome has been implicated in the pathogenesis of chronic rhinosinusitis (CRS). However, the mycobiome remains largely understudied, and microbial alterations associated with specific CRS subtypes have yet to be delineated. The objective of this study is to investigate the fungal and bacterial microbiome of sinus mucosa in CRS patients with and without nasal polyposis (CRSwNP and CRSsNP) versus healthy controls. ...continue reading "Fungi and Bacteria In The Sinus Microbiome"

Published on Leave a comment on Snot Transplants for Sinusitis?

There are 2 small studies that recently looked at the issue of snot transplants as a treatment for chronic sinusitis. The idea behind snot transplants or sinonasal microbiota transplants is similar to fecal transplants - it's a transplant containing the entire microbial community (fungi, bacteria, viruses) in the form of a sample of snot or nasal mucus from a healthy donor to a recipient with chronic sinusitis (sign of an unhealthy sinus microbiome).

This idea has huge potential as a treatment. The goal in a sinus snot transplant is to have the healthy donor's snot (the mucus) take over and change (engraftment) the recipient's unhealthy sinus microbiome. The hope is that this will restore a healthy sinus microbiome in the person with chronic sinusitis, resulting in sustained improvement in sinus health.

The results from the studies are definitely encouraging, but also a bit mixed. For example, there was sustained improvement (up to 180 days) in 2 out of 3 patients in the 2024 study, but why not the third person? Also, illness may appear in the recipient of the transplant (see patient narratives in the first study). Also, why did some people drop out after the first snot transplant in the 2022 study? In both small studies, most of the the healthy donors were the recipient's spouse or a close friend.

The one concern that everyone has is of the possibility of some unknown disease being transferred from the donor to the recipient. [Note: Post about the Swedish study before it started]

Excerpts from Dec. 2022 Allergy and Rhinology: Upper airway microbiome transplantation for patients with chronic rhinosinusitis

The study, involving patients with CRSsNP, was of an open pre-post interventional design and involved 13 days of antibiotics (amoxicillin/clavulanate 875 mg/125 mg three times daily or, in case of penicillin-allergy, clarithromycin 500 mg two times daily) followed by five daily upper airway microbiome transplants.....All patients had over several years (i.e., far longer than the time span of this study) failed repeatedly on medical therapy and had undergone endoscopic sinus surgery (ESS) with a minimum of bilateral middle meatus antrostomies/ethmoidectomies

3.1 Patient narratives and adverse events Three patients opted not to participate further after visit 1 (V1). The remaining 22 patients completed the trial. Eighteen reported airway symptoms such as cough, sore throat, blocked or runny nose, or common cold-like symptoms during or soon after the transplant procedure. Seven indicated gastrointestinal problems, mainly diarrhea. One patient developed acute purulent rhinosinusitis and pneumonia 34 days after the last transplant. One patient developed a urinary tract infection, and one was diagnosed with diabetes type 2 (2 weeks before V8). One patient developed fever and cough during, and one experienced sinusitis-like symptoms 5 days after the transplant series. The latter two incidents were considered potentially caused by the microbiome transplant series. ...continue reading "Snot Transplants for Sinusitis?"

Published on Leave a comment on Twenty Tips For Sinus Health
Credit: Wikipedia

It turns out there are a number of simple things you can do to keep your sinuses healthy and reduce the chances of developing another sinus infection. A lot of these suggestions involve preventing nasal stuffiness and congestion, and to improve sinus drainage.

Because, as we all know - once those nasal passages get clogged, the odds of another sinus infection increases. When the nasal passages are inflamed or blocked, then mucus can't properly drain from the sinuses.

Chronic sinusitis goes hand in hand with rhinitis, which is why the medical literature refers to chronic sinusitis as chronic rhinosinusitis. It can be allergic rhinitis or non-allergic rhinitis - that is, with known or unknown triggers leading to a dripping nose, congestion, increased mucus, even sneezing or coughing. Dust, irritants, fragrances, allergies (e.g., tree pollen), spicy foods, and air pollution are all examples of triggers.

Some of the following tips are to avoid fragrances and scented products. This is because they are considered indoor air pollutants. They release chemicals that cause nasal inflammation, which can result in rhinitis symptoms, and possibly lead to sinusitis. All air pollution (whether indoors or outdoors) can cause nasal inflammation.

TWENTY TIPS FOR SINUS HEALTH:

1) Sleep with 2 or more pillows in a semi-upright position. This helps with mucus drainage in the nasal passages.

2) When needed, use an ordinary saline nasal rinse once or twice a day. This helps with nasal congestion.

3) When needed, use a 12-hour 1200 mg guaifenesin non-prescription product (e.g., Mucinex) at night. It helps to thin mucus.

4) Can use antihistamines (for allergies) and nasal corticosteroid sprays (especially for nasal polyps) when needed.

5) Can use a premade saline mist spray (e.g., Arm and Hammer simply saline mist) to help relieve minor congestion. This can be helpful any place with stuffy air.

6) Shower at night to wash away dust and allergens.

7) Use unscented personal care products as much as possible (e.g., unscented deodorant). Or if that's not possible, try for minimally scented products.

8) Avoid cigarette smoke and smoke-filled air as much as possible.

9) Consider limiting your intake of alcohol. Alcohol causes temporary nasal inflammation in everyone, but for some persons the swelling lasts a long time and can cause nasal congestion and other symptoms.

10) Avoid the use of scented products in the home, including air fresheners, scented candles, incense, essential oils, clothes detergents, and scented dryer sheets (fragrances/chemicals are air pollutants - in the air, get on our clothes, and us).

11) Frequently open windows to air out the home, even if only for a few minutes. Use bathroom fans if you have them.

12) When cooking, use a kitchen exhaust fan that vents to the outside, especially if you have a gas stove and oven.

13) Vacuum frequently with a good vacuum cleaner.

14) Wall to wall carpeting can be a problem for many, especially in the bedroom. They accumulate dust and contaminants, which are hard to clean.

15) Change your A/C and heating filters frequently.

16) Consider getting a good air purifier (check Consumer Reports and Wirecutter. Especially powerful are the Austin Air Purifiers.)

17) Make sure there isn't a hidden mold problem, and clean up any mold you find. Also, make sure that water isn't getting into the house. [CDC guidelines]

WHEN STARTING TO FEEL SINUSITIS SYMPTOMS:

18) Get enough sleep. When sleep deprived, people can feel “mucusy”. They are also more susceptible to viruses.

19) At the start of a sore throat or infection - suck on a zinc tablet or lozenge. It may stop the viral infection.

20) Use L. sakei (e.g., Lanto Sinus) at the start of a sinus infection. (Stop using it when feeling better.)

Additionally, try to boost your immune system by eating a healthy diet (one rich in fruits, vegetables, whole grains, seeds, nuts, legumes, olive oil), getting plenty of sleep, drinking plenty of  water, and getting enough exercise or physical activity (Government guidelines say at least 2 1/2 hours per week of physical activity, including walking).

Can also take a vitamin D supplement (research shows it can decrease the number of respiratory infections) or get enough sunlight. After all, vitamin D is called the sunshine vitamin.

Good health!

Published on Leave a comment on Eleven Years of Successfully Treating Sinus Infections With Probiotics

It is now my twelfth year of successfully treating sinus infections with only the probiotic Lactobacillus sakei. My twelfth year! This includes regular sinus infections, my initial chronic sinusitis, and even when there are just a few sinus symptoms (you know, the gradual slide toward sinusitis).

Amazingly, no antibiotics and no antibacterials in all this time! Just using a product with the beneficial bacteria L. sakei when needing it is all it takes. To say it feels miraculous is an understatement.

Studies show that the beneficial bacteria Lactobacillus sakei occurs naturally (in tiny amounts) in healthy sinuses, but is depleted or missing in those with sinusitis. It is normal for a community of bacteria, viruses, fungi to live in the sinuses - this is the sinus microbiome.

My journey started in the winter of 2013 after reading research in late 2012 about L. sakei. I started with kimchi back then, but in the last few years I've used the product Lanto Sinus, which contains a kimchi-derived strain of Lactobacillus sakei.

In the past decade, I have heard from hundreds of people from all over the world, and the majority agree that L. sakei works great as a sinus treatment! Other probiotic species just don't work, even though they may help with some symptoms. [See Best Probiotics For Sinusitis for details on results and products used.]

Lessons Learned Over the Past Eleven Years:

1) Lactobacillus sakei alone is enough to treat sinus infections or sinusitis. It helps with all the associated symptoms: mucus dripping down the throat (post-nasal drip), sinus pressure, sinus headaches, earaches and coughs from sinusitis, etc.

2) Using L. sakei (whether in kimchi or Lanto Sinus) should take about a minute! No fancy methods or protocols needed.

3) Only use L. sakei when needed. This means when there are sinus symptoms (e.g., lots of mucus, post nasal drip) or you're sliding towards sinusitis. No need to wait till the sinus infection is full-blown.

4) Stop using it when feeling better. Don't use it daily or as a preventive, but only when needed. There are many species of microbes living in the sinuses, so you don't want to flood the sinuses with just one species for weeks on end.

5) After using it for a few days, evaluate whether you can stop or whether you need to keep using it longer. The sinuses frequently keep improving and rebalancing after stopping L. sakei.  One can always use more if needed.

6) People use L. sakei products (e.g., Lanto Sinus) all sorts of ways. Can mix the powder with bottled/sterile water and dab/smear in nostrils (regular use). Or swish alone in the mouth - a gentle and cautious method. Or use it with saline nasal irrigation - a strong way to use. Yes, you can use less than the recommended dosage.

Please note: The only way kimchi (the juice) has an effect is by dabbing or smearing a little in the nostrils.

7) Don't overdo it. Using a little bit in the nostrils (as described in Sinusitis Treatment Summary) is sufficient. Let the little buggers travel on their own throughout the sinuses!

8) L. sakei normally lives in healthy sinuses, which is why it is such an effective sinus infection treatment for so many people. L. sakei overpowers or dominates over harmful (pathogenic bacteria), and so researchers are now studying its use for a variety of health conditions.

9) Over time a person typically needs less L. sakei to treat sinus symptoms. The L. sakei colonizes in the sinuses (can be short-term or long-term). Weeks or months can go by without needing to use it again.

10) When L. sakei works for a person, it can feel miraculous as sinusitis symptoms disappear, frequently within a few days. Others have slower improvement. Unfortunately, it doesn't work for everyone and only self-experimentation determines whether it does and how best to use it.

11) It is OK to do ordinary nasal irrigation once or twice a day on same day as using L. sakei product. Also OK, if needed, are nasal corticosteroids (e.g., Flonase), decongestants (e.g., Sudafed), and guaifenesin (e.g., Mucinex).

12) Every person's sinus and respiratory microbiome is a little different, which is why finding what works for a person is self-experimentation.

13) After using L. sakei in any product (e.g., kimchi) for an extended time, can start feeling like it's not working well anymore or some sinus symptoms may appear (e.g., mucus). This could be overuse or too much of a product - that is, flooding the respiratory system with too much of whatever you're using, and now need to add a little bit of other beneficial bacteria.

Simply stop using the product and try adding some other microbes into the respiratory system for a day or two or even more if needed - this will help rebalance the sinuses. Open a multistrain probiotic capsule and swish the powder in the mouth. [See Sinusitis Treatment Summary] Lactobacillus and Bifidobacterium species are OK to use - they are normally found in our bodies in tiny amounts.

This first happened in 2013 when I kept using kimchi even when sinuses felt healthy - I thought I needed a boost several times a week. Nope. After many months I started developing sinus symptoms and only switching to a different type of kimchi got rid of the symptoms. Over the years I've done this with every L. sakei product, and adding other microbes for a day or more solved the problem, and I could go back to the original product when next needed.

14) One possibility why sinus infections keep occurring over the years, even if less frequently, is because other bacterial species are also diminished in those with sinus infections (as shown by sinus microbiome studies). And these species are not available in probiotics.

15) People report that using L. sakei has helped bacterial conditions other than sinusitis. This includes earaches, coughs (bronchitis), tonsil stones. Sounds like lots of self-experimentation going on!

Good health!

Published on Leave a comment on Kimchi Made With Seafood and Vegan Kimchi Contain the Same Microbes

Over the years I've received many questions about vegan versus kimchi that contains seafood. Are the microbes in the kimchi the same?

One reason this is an important question is because at certain stages of kimchi fermentation the beneficial bacteria Lactobacillus sakei (which treat sinusitis in many people) appears for a time. And during that time when L.sakei is present, dabbing a little kimchi juice in the nostrils helps and treats many individuals with sinusitis. Amazing, yes?

Many people prefer to treat sinusitis with vegan kimchi - which is also my personal preference. I don't want to worry about what is in the seafood used in kimchi. Therefore, it's vegan kimchi for me.

Earlier studies have suggested that even though kimchi is made with cabbage, the L. sakei grows from the surface of raw garlic used in making  the kimchi. From the M.A. Zabat et al (2018) study:

"Because kimchi is made without the use of a starter culture, the raw ingredients play a key role in establishing the bacterial community that is responsible for fermenting kimchi (Jung et al., 2011; Lee et al., 2015)".

"Large amounts of garlic are associated with more kimchi-associated LAB [lactic acid bacteria] in the final product (Lee et al., 2015)." [Note: L. sakei is one of the lactic acid bacteria in kimchi]

This is why the 2018 study, which I just read, is so interesting. The researchers found that both vegan (no seafood)and kimchi made with seafood (e.g., fish sauce) contain the same microbes after fermentation. They may have started out with different populations of microbes, but during fermentation the microbes become similar.

"We found that, despite initial differences in microbial composition between vegan and non-vegan kimchi, there was no notable difference in the final products. Ultimately, the microbial community of both vegan and non-vegan kimchi is dominated by Lactobacillaceae and Leuconostocaceae, and lacks the Enterobacteriaceae found in the fish sauce or miso paste."

Well... that's a relief. What kimchi you choose to eat and use as a sinusitis treatment is personal preference. It's all good. And yes, fermented foods such as kimchi are great for the gut microbiome. They increase gut microbial diversity (good!) and reduce inflammation.

From Physics News: Vegan and traditional kimchi have same microbes, study finds

Good news, vegans: A new study finds that kimchi made without fish products has the same type of bacteria as more traditionally made kimchi. That finding suggests that any "probiotic" benefits associated with traditional kimchi could be present in vegan versions as well. ...continue reading "Kimchi Made With Seafood and Vegan Kimchi Contain the Same Microbes"

Published on Leave a comment on Study Shows High Levels of Chronic Sinusitis After Sinus Surgery

Over the years I've talked to many people who have had sinus surgeries for chronic sinusitis, many of whom have had more than one surgery. And yet they keep suffering from chronic sinusitis for years . The big question: How many people are actually helped or cured by standard sinus surgery such as FESS (Functional Endoscopic Sinus Surgery)?

Well, I came across a study from 2016 looking at long-term sinus surgery (FESS) results on 560 adults. Three to 5 years after the FESS surgery, the results were pretty shocking - about 43.7% of persons were still suffering from chronic sinusitis (the researchers called it "uncontrolled"), 36.8% were somewhat better (partly controlled), and only 19.5% were feeling healthy (well controlled). Common sinus symptoms in the "uncontrolled" group were: headache, sleep disturbance, postnasal drip/secretions, and altered sense of smell.

The researchers mentioned another smaller study with similar results that looked at persons 12 years after FESS surgery: 47.4% still had chronic sinusitis (uncontrolled) and only 26.3% were doing well (controlled). They also concluded: "Therefore, better treatment strategies leading to higher disease control are warranted in CRS (chronic rhinosinusitis) care." 

Hello??   Instead of surgery, try focusing on the sinus microbiome by using beneficial bacteria such as L. sakei (in Lanto Sinus, kimchi). Researchers are looking at using beneficial bacteria in the future for sinusitis treatment.

Published on 1 Comment on Study Finds No Effect From Two Sinus Products

This month a number of persons asked me about the probiotic Lactococcus lactis (in Probiorinse) and whether it works. This product is marketed to people with sinusitis or sinus infections, with the message that it improves the sinus microbiome and sinus health. Does it?

Unfortunately, the research says no. A well-done study published last year found that the bacteria Lactococcus lactis (Probiorinse) doesn't help to improve sinus symptoms in those with sinus issues. Yes, that bacteria is found in the sinuses, but it is not a keystone bacteria (one with a big effect) in sinus health.

The study compared the Probiorinse (Lactococcus lactis) product to Xlear (xylitol) and regular saline rinses.

The researchers tested xylitol, the probiotic Lactococcus lactis, and ordinary saline rinses separately for one month in a group of persons with chronic sinusitis. They found that none of these improved sinusitis symptoms or sinus microbial diversity (the sinus microbiome). In other words, there were no significant differences among the 3 groups.

Those with chronic sinus problems still had them at the end of the study, and their sinus microbiomes and symptoms were still very different from those of the healthy participants.

By the way, another study analyzed Lactoccocus lactis (using the product Probiorinse) against some strains of harmful bacteria (Pseudomonas aeruginosa) collected from persons with chronic sinusitis and found "no effect on 4 strains, a modest inhibitory effect on one strain, and a modest proliferative effect on one" (it increased this harmful strain!). Basically no effect - not a good result.

Bottom line: Stick with ordinary saline rinses to help with sinus congestion. The medical view is that saline nasal irrigation is recommended because it helps a little with nasal stuffiness or congestion, even though this effect is temporary (a few hours?). Also, try the probiotic Lactobacillus sakei, which is a keystone bacteria in the sinuses and which kills/dominates over many harmful bacteria (e.g., Staphylococcus aureus - a problem bacteria in many with sinusitis).

Excerpt from the 2021 study by Lambert PA, et al., in the medical journal  Laryngoscope Investigative Otolaryngology:  Microbiomics of irrigation with xylitol or Lactococcus lactis in chronic rhinosinusitis

No significant trends in alpha or beta diversity as a result of treatment were observed. SNOT‐22 score did not change significantly following treatment with xylitol, L. lactis, or saline. [Translation: the microbiome (alpha and beta diversity) didn't change, and symptoms (SNOT-22 score) didn't change]

Published on 15 Comments on Nine Years of Successfully Treating Sinus Infections With Probiotics

It is now 9 full years since I first started successfully treating both chronic sinusitis and regular sinus infections using only  the probiotic Lactobacillus sakei. This means no antibiotics or any other antibacterial has been used in more than 9 years! This is amazing – ten years ago I didn't believe this to be possible.

Research shows that the beneficial bacteria Lactobacillus sakei occurs naturally (in tiny amounts) in healthy sinuses, but is depleted or missing in those with sinusitis. (You know we all have a sinus microbiome - bacteria, fungi, and viruses living in the sinuses, yes?) I started by using kimchi after reading research in late 2012, but the last few years I've used the refrigerated product Lanto Sinus, which contains a kimchi-derived strain of Lactobacillus sakei. 

I have heard from hundreds of people since the blog started, and the majority agree - Lactobacillus sakei works great as a sinusitis treatment! (Other probiotic species just don't work.) [See Best Probiotics For Sinusitis for details on results and products used.]

Lessons Learned During Past 9 Years:

  1. Lactobacillus sakei alone is enough to treat sinusitis or sinus infections. Don't need fancy concoctions or fancy protocols when using it. Using it (whether in kimchi or Lanto Sinus) should take under 1 minute a day!
  2. Only use Lactobacillus sakei when needed - when there are some sinus symptoms (e.g., lots of mucus, post nasal drip) or you're sliding towards sinusitis. No need to wait till the sinus infection is full-blown.
  3. Stop using it when feeling better. Just like with antibiotics, don't take it daily and routinely, but only when needed.
  4. Use for a few days and evaluate whether you can stop or whether you need to keep using it longer. Frequently the sinuses keep improving even after stopping Lactobacillus sakei. One can always use more if needed.
  5. Lactobacillus sakei normally lives in healthy sinuses, which is why it is such an effective sinus infection treatment for so many people.
  6. Over time (whether weeks or months) a person typically needs less Lactobacillus sakei to treat sinus symptoms. The L. sakei colonizes in the sinuses - whether short-term or long-term.
  7. Swishing a product like Lanto Sinus in the mouth alone is a gentle and cautious way to use the product. Using it in the nostrils is a stronger way to use the product.
  8. Don't overdo it. Using a little bit in the nostrils (as described in Sinusitis Treatment Summary) is sufficient. Let the little buggers travel on their own throughout the sinuses!
  9. If Lactobacillus sakei works for a person, it can feel miraculous as sinusitis symptoms disappear, frequently within a few days. Others have slower improvement. Unfortunately, it doesn't work for everyone and only self-experimentation determines whether it does - after all, everyone's sinus microbiome is different.

Hopefully this offers hope to sinus infection sufferers. Good health!
