Why Chronic Sinusitis Remains Chronic

By Cesar Collado

Chronic rhinosinusitis (CRS) is a challenging disease for both allergists and otorhinolaryngologic physicians (“ENTs”), partly because of its poorly understood pathophysiology and partly because of its limited treatment options, which remain to be mostly antibiotics. It affects approximately 35 million adults and 6 million children.

When experiencing chronic rhinosinusitis (“CRS”), it is difficult to understand why the infection reoccurs so often, even after antibiotic treatment and/or surgery.  One reason for this is the possible coinfection or colonization of fungus in CRS.  In 1999, The Mayo Clinic published a study where Allergic fungal sinusitis was diagnosed in 94 (93%) of 101 consecutive surgical cases with CRS, based on histopathologic findings and culture results. 1.

A later publication by many of the same researchers in 2006 focused on the role of airborne fungi in CRS. This paper described the process where fungi trigger an immune reaction in sinus tissue causing inflammation and mucous production. The immune system reacts to the fungi by deploying eosinophils.2. The eosinophils are released at levels far exceeding those needed to remove the fungi. This increased inflammation results in damage the sinus epithelial lining and cilia in the sinus tissue lining. When a rupture occurs, damage to the smooth endothelial lining creates cavities in the sinus, where bacteria (Staphylococcus aureus, locally found on the skin, hair, and in the nose) binds to the mucosal pits caused by the lysis of eosinophils when they attach to fungi to destroy it. With continuous inhalation and over time, additional Staphylococcus bacteria bind to form a protective matrix around bacteria, called biofilm.  This matrix attracts additional bacteria, including fungi and other pathogens.

A biofilm comprises any consortium of microorganisms (bacteria and fungi) in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix.  The sticky extracellular matrix protects the bacteria and fungi from the immune system and antibiotics.3.

According to the National Institutes of Health (NIH) about 65% of all microbial infections and 80% of all chronic infections are associated with the presence of biofilms. Biofilm formation is a multi-step process starting with fungal or bacterial attachment to a surface, and then to the formation of a micro-colony that leads to the formation of three-dimensional mature and ultimately diverse pathogens. During biofilm formation, many species of bacteria are able to communicate with one another to form a communal barrier against challenges to their well-being.  Thus, bacteria in biofilm are less accessible to antibiotics and the human immune system and pose a bigger threat to public health as they are involved in an ever-growing variety of infectious diseases.

Chronic Sinusitis Mold Sickness

The best treatment for biofilm formation in the sinuses, first line, is nasal irrigation with saline solution to just move the stuff along. If all the people in the world that have chronic sinusitis used nasal saline irrigations 2x per day, you can speculate that a significant proportion would not have any symptoms anymore.  An analogous example to illustrate the concept of using nasal irrigation to prevent biofilm development in the sinus is brushing and flossing your teeth to prevent the formation of plaque.7.

The mouth hosts a variety of bacteria and plaque is actually a formation of a biofilm on the teeth.  Brushing your teeth and flossing 2 times per day are the preventative activities we perform to prevent dental disease and maintain mouth health. These activities, like nasal rinsing, stop the health issues associated with the formation of biofilm BEFORE it occurs.

Biofilms Host Both Bacteria and Fungi in the Matrix

Distinct pathogens such as Staphylococcus aureus and Aspergillus can coexist in biofilms.4.  For these reasons, treatment for CRS using antibiotics may provide temporary relief, but will not fully penetrate and dissolve the remaining biofilm. As soon as the antibiotic course is completed, the bacterial and/or fungal infection that is still present will become recalcitrant or chronic.  The fungal presence in biofilms also allows for “in -vivo” mycotoxin production, meaning that mycotoxins are being actively produced within the biofilm and within the host’s body.  To support this, science has shown an increase of the mycotoxin, Gliotoxin, from Aspergillus fumigatus biofilm formation in the sinus.5.   Increased gliotoxin production makes biofilm-related sinus infections particularly difficult to treat. –

Because fungal sinusitis poses the risk of mycotoxin production in biofilm deep in the sinuses, adjacent to the cerebral spinal fluid and the brain, cognitive dysfunction can likely continue as the biofilm matures and disburses particles into the sinuses and the brain. Brain fog, headaches, memory issues, motor function issues throughout the body, dizziness, etc. may not ever go away while biofilms remain in the sinuses.

Biofilm Treatment and Prevention

Antibiotics are dosed to treat planktonic (individual, free-flowing) bacteria; however, biofilms harbor a 10–1000-fold higher resistance to antimicrobials due to the slimy matrix protection over the microbial filled cavities.5. Further, antibiotics do not kill mold or fungi.  Although ENT physicians will acknowledge and diagnose acute fungal sinusitis and will remove fungal balls surgically, traditional protocols to treating the infection have not evolved over the years to address fungus.  Standard treatment for infection usually includes antibiotics and possibly surgery.

Another observation is that most ENT physicians skip the diagnostic or culture identification process to determine species of the infection in the interest of time, cost, and practicality, since removing the infection physically and treatment with antibiotics is standard. But, the utilization of antifungal medications is not standard.

Taking any medication designed to kill organisms or cells carries risks to the patient demonstrated through side effects. For example, antibiotics impact gut flora and cause GI distress and fungal overgrowth. Topical agents have the least danger of toxicity because they are not distributed systemically or metabolized by the liver and kidneys.  More toxic agents used to kill fungal or cancer cells, that are resilient, can have severe toxicities to the liver and/or kidneys when metabolized.  Oral antifungals have improved and provide limited toxicities as older agents are dosed to minimize danger to the patient but are limited in their efficacy.  Intravenous medications have severe organ and metabolic dangers.

Some ENT physicians have discovered the efficacy of using the more potent antifungals topically in the sinuses have had success in treating chronic fungal sinusitis. With current evidence pointing to the fungal etiology of CRS, there has been a trend towards treatment of CRS with older systematic antifungal medications used topically in the sinuses.   With current evidence pointing to the fungal etiology ofCRS, there has been a slow to adapt trend towards treatment of CRS with topical antifungal medication.

With evidence of fungal causes of CRS, there has been a trend by some ENTs to treating CRS with topical antifungal medication used typically intranasally in a “pressure wash” approach. The toxicity of systematic intravenously has been characterized with significantly higher concentrations than are used topically in the sinuses. There is also clear evidence that amphotericin b is poorly absorbed in the gut when taken orally.  Therefore, there is little or no potential for systemic exposure when used topically and intranasally.8.

Endoscopic Surgery for Chronic Fungal Sinusitis

Doctor Dennis and other ENTs often perform endoscopic sinus surgery to remove the obstructions that Chronic Sinusitis Mold Sicknesscause mucous retention and prevent proper sinus drainage that then causes infection.  During this surgery,
Chronic Sinusitis Mold Sicknessdiseased tissue and visible biofilms are physically removed using suction.  Following the physical alteration of the anatomy, new tools to essentially “pressure wash” the sinus lining removes residual biofilms, mold, and mycotoxins.  The sinuses are then irrigated to eliminate residual fungal hyphae.

Biofilm Maintenance and Prevention

Chronic Sinusitis Mold SicknessIn addition to nasal rinsing with CitriDrops Dietary Supplement, Dr. Dennis also prescribes an anti-fungal in a mixture with saline to deliver via nebulizer. This is effective in distributing the antifungal deep into the sinuses with daily consistency.

Sinus Defense is also helpful as it targets the same fungi that tested positive in the study described in the May Clinic article in 1999.CellTropin then used to provide support for the pituitary gland which is usually impaired from the mycotoxin onslaught. This is an important piece of treatment because the pituitary controls 8 hormonal systems.  Sinus infections, inflammation, and the presence of mycotoxins in the body can damage tissue and gland function.  The result is often chronic fatigue and adrenal dysfunction.

Tip to Finding an ENT That Will Listen to a Patient’s Concerns About Mold and Fungus

Many patients suggest to their ENT that mold might be their issue.  This suggestion often finds an unsympathetic ear and a dogmatic opinion as it may be interpreted as trying to tell them how to practice medicine.  This is frustrating.  Chronic Sinusitis Mold SicknessOne solution is that any patient can call a local “Compounding Pharmacy” and ask which local ENT physicians prescribe anti-fungal medications in drops or nebulization. Compound Pharmacies provide physicians the ability to custom mix or dose a patient with existing medicines.

Doctors must have these critical sinus delivered prescriptions specially made in a compounding pharmacy, and there is no violation of any rules or laws for a pharmacist to provide a patient with this information since no personal patient information is being solicited from or provided for such an inquiry.  Physicians having antifungals compounded for patients are more likely to already treat fungal sinusitis given the specific use of the product.  This also saves time and money.

    Can you make the CitriDrop Nasal Spray without Benzalkonium Chloride?
    It seems like a good product except for that.
    Couldn’t the citrus seed oils be used for a preservative instead? Benzalkonium Chloride could be doing harm: https://www.ncbi.nlm.nih.gov/pubmed/7553242 plus reports of it causing loss of smell/taste.

      Benzalkonium chloride is a quaternary ammonium compound that has several uses. In products where it is used as an active ingredient, it is a surfactant and a sanitizing agent. the toxic effects described in the article you linked to describe the cons of using a quaternary ammonium compound. It is a toxic molecule when used in amounts where it is the active ingredient.

      Many, many products used for the eyes and sinuses use the compound in minute amounts as a preservative. This is necessary for natural products to have a shelf life to be made and sold to be effective. Without a preservative, the product would not be viable for us to make it available to patients.

      If this is critical to you, you shouldn’t use Citridrops. I personally have not heard of toxic episodes with Citridrops in patients due to quaternary ammonium. I will do some further investigating on this topic to see if there are alternatives. Producing a safe, non-toxic product is critical for us in production.

        I have been using all of the microbalance products and love them!! I am wondering if I could just try nebulizing the citri drops without the Amphotetecin B?? We have remediated our home and the screening plates look good! Continuing to work on removing the mycotoxins from our bodies.

          Thank you for your question. The amphoteracin solution is meant to be utilized by an ENT. It specifically addresses mold and mycotoxins in the sinus tissues. The resulting symptoms are severe cognitive symptoms, headaches, and fatigue. If you are not having these symptoms, rinsing or using a nebulizer of citridrops will have similar effect. 2X/day rinsing is consistently the most effective way to rinse and remove mold and mucous from your sinuses. This allows your body to heal.

          If you have these symptoms, this is a solution that I know works and is safe to do.
