Chronic illnesses can be incredibly difficult to diagnose and treat, leaving both patients and doctors feeling stuck. One condition that often goes undetected is Chronic Inflammatory Response Syndrome (CIRS), triggered by exposure to harmful toxins such as mold and bacteria. In a recent episode of the Integrative Health Podcast, Dr. Joseph Musto, a seasoned expert in clinical lab testing, dives deep into the complexities of CIRS. He emphasizes the importance of proper testing to uncover the true source of the illness and shares insights on how targeted treatment can make a real difference.

Dr. Musto’s extensive background in clinical laboratory medicine has made him a pioneer in developing advanced testing methods for CIRS and MARCoNS (Multiple Antibiotic Resistant Coagulase-Negative Staphylococci). During the episode, he shares valuable insights about how these bacterial infections and biotoxins can trigger chronic inflammation, leading to various health complications, and why proper testing is crucial for both diagnosis and treatment.
What is Chronic Inflammatory Response Syndrome (CIRS)?
CIRS is a condition that affects multiple systems in the body, causing a wide range of symptoms. It’s triggered by exposure to biotoxins, which are often found in water-damaged buildings, mold, bacteria, and sometimes even tick bites. These toxins enter the body and disrupt the immune system, leading to inflammation that impacts organs, hormones, and overall health.
The term "CIRS" was coined by Dr. Ritchie Shoemaker in the early 2000s. He discovered that people exposed to toxins, such as those found in water-damaged environments, often developed chronic symptoms that didn’t resolve with conventional treatments. Through his research, Dr. Shoemaker found that these toxins could disrupt the body’s immune system, making it difficult to eliminate the harmful substances and leading to long-term inflammation.
One of the key points Dr. Musto discusses in the podcast is that CIRS isn’t widely recognized by mainstream medicine. Many conventional doctors may not be familiar with the condition, which is why patients often face challenges in getting a proper diagnosis. However, with the right tests, CIRS can be diagnosed, and treatments can be tailored to each patient’s specific needs.
Why Testing is Essential for Diagnosing CIRS
A recurring theme throughout the podcast is the importance of lab testing to diagnose CIRS. Dr. Musto emphasizes that without the appropriate tests, patients may go undiagnosed, leading to prolonged suffering and potentially worsening symptoms. One of the major challenges with CIRS is that it mimics other conditions, causing confusion for both patients and physicians.
For example, common symptoms of CIRS include:
- Chronic fatigue
- Brain fog and cognitive issues
- Respiratory problems
- Joint and muscle pain
- Gastrointestinal issues
- Sensitivity to light or sound
- Unexplained weight gain or loss
These symptoms can easily be mistaken for other illnesses, making CIRS difficult to detect without targeted testing. Dr. Musto highlights that conventional doctors may be skeptical of CIRS because it involves complex, multi-system symptoms. This is where lab testing comes into play.
By running specific tests, such as visual contrast sensitivity (VCS) tests and HLA genetic tests, healthcare providers can detect whether a patient is genetically predisposed to biotoxin illness. Dr. Musto explains that individuals with certain genetic markers may be unable to naturally eliminate toxins from their system, making them more susceptible to CIRS.
Understanding MARCoNS: The Hidden Bacterial Threat
An important aspect of CIRS that Dr. Musto elaborates on is MARCoNS. This acronym stands for Multiple Antibiotic Resistant Coagulase-Negative Staphylococci, a type of bacteria commonly found in the nasal passages of individuals with CIRS. While MARCoNS isn’t typically associated with sinus infections or rhinitis, it poses a significant problem for those suffering from biotoxin illnesses.
MARCoNS bacteria produce toxins that suppress the immune system, particularly a hormone called melanocyte-stimulating hormone (MSH). MSH is essential for regulating immune function, inflammation, and the production of various hormones. When MARCoNS reduces MSH, it leads to immune system dysfunction and a range of symptoms associated with CIRS, such as brain fog, fatigue, and chronic inflammation.
Dr. Musto underscores that eliminating MARCoNS is a critical step in treating CIRS. Many patients with CIRS experience ongoing symptoms until these bacteria are eradicated from the body. He discusses various treatments, including the use of nasal sprays, binders, and antimicrobial therapies to remove MARCoNS and restore balance to the immune system.
Testing for MARCoNS: A Key to Recovery
Dr. Musto’s laboratory specializes in testing for MARCoNS, providing clinicians and patients with valuable information that can guide treatment decisions. One of the key points he emphasizes is that testing for MARCoNS requires a nasal culture, which is then analyzed for the presence of the bacteria and its resistance to antibiotics.
What makes MARCoNS particularly challenging is its ability to form biofilms, a protective layer that makes it difficult to eradicate with conventional antibiotics. Dr. Musto’s lab has developed specialized testing methods to detect both MARCoNS and the biofilms that protect it. This allows clinicians to choose the most effective treatments, which may include biofilm disruptors and longer courses of therapy.
In addition to testing for MARCoNS, Dr. Musto offers biofilm tests and fungal cultures to provide a complete picture of a patient’s nasal microbiome. This comprehensive approach ensures that no aspect of the infection is overlooked, which is crucial for achieving long-term recovery.
Effective Treatments for CIRS and MARCoNS
Once CIRS and MARCoNS are identified through testing, the next step is treatment. Dr. Musto shares several treatment options that have been proven effective in reducing inflammation, eliminating toxins, and clearing MARCoNS infections.
One of the most important treatments for CIRS is the use of binders, such as cholestyramine, which helps remove toxins from the body. Cholestyramine binds to toxins in the digestive system and prevents them from being reabsorbed into the bloodstream. This is a key step in detoxifying the body and reducing the inflammatory response triggered by biotoxins.
For MARCoNS, treatment typically involves the use of nasal sprays containing antimicrobial agents like silver or EDTA (ethylene diamine tetra-acetic acid). These sprays work by disrupting the biofilms that protect MARCoNS and killing the bacteria directly. Dr. Musto also mentions the use of peptide therapies like VIP (vasoactive intestinal peptide), which can help restore MSH levels and reduce inflammation.
However, Dr. Musto cautions that treating MARCoNS can take time. In some cases, patients may need to use nasal sprays and other treatments for several months to fully eradicate the infection. He also stresses the importance of testing throughout the treatment process to ensure that the bacteria are being effectively eliminated.
The Importance of Long-Term Maintenance and Monitoring
Even after MARCoNS has been cleared, Dr. Musto emphasizes that ongoing maintenance is essential to prevent reinfection and maintain immune system balance. He recommends that patients continue using maintenance doses of nasal sprays and other antimicrobial agents for several months to ensure that the infection doesn’t return.
Additionally, monitoring blood tests and other markers of inflammation is crucial for tracking a patient’s progress. Dr. Musto discusses the role of cytokines, which are proteins that regulate the immune response, in CIRS. Elevated levels of cytokines can indicate ongoing inflammation, even after MARCoNS has been treated.
By monitoring these markers, healthcare providers can adjust treatment plans as needed and ensure that patients continue to improve over time. Dr. Musto’s laboratory offers a range of tests to help clinicians track these markers and make informed decisions about patient care.
