Mold Mycotoxin Illness & CIRS: Environmental Neuro-Immune Triggers

1. The Genetic Susceptibility: HLA-DR Gene Haplotypes

Approximately 24% of the general population carries human leukocyte antigen (HLA-DR/DQ) immune response haplotypes that prevent dendritic cells from properly presenting lipophilic biotoxins (such as ochratoxins, trichothecenes, and aflatoxins) to B-cells for antibody production.

In these individuals, inhaled or ingested mycotoxins are never cleared. Instead, they continually circulate through the enterohepatic circulation, binding to toll-like receptors and activating the innate immune system while suppressing the adaptive immune system.

2. Validated Laboratory Biomarkers

• Transforming Growth Factor Beta-1 (TGF-β1): A potent pro-inflammatory cytokine. Normal: < 2,380 pg/mL. In active CIRS, levels frequently exceed 5,000–10,000 pg/mL, driving microvascular remodeling and T-regulatory cell dysfunction.
• Complement C4a: A split product of complement activation. Normal: < 2,830 ng/mL. Levels spike within hours of re-exposure to water-damaged buildings.
• Melanocyte-Stimulating Hormone (MSH): Hypothalamic neuropeptide regulating mucosal immunity and sleep. CIRS patients exhibit profound MSH deficiency (< 35 pg/mL), leading to leaky gut and chronic non-restorative sleep.
• Visual Contrast Sensitivity (VCS): A neurological test measuring retinal capillary hypoperfusion. Patients lose the ability to differentiate subtle shades of gray.

3. The 3-Step Shoemaker Treatment Roadmap

1. Removal from Exposure (HERTSMI-2 < 10): The patient must be removed from water-damaged buildings verified by professional ERMI/HERTSMI-2 dust DNA testing.
2. Enterohepatic Binders: Prescription Cholestyramine (CSM, 4 g 4x daily) or Colesevelam (Welchol, 625 mg 2 tabs 3x daily) taken on an empty stomach to bind biliary mycotoxins and prevent reabsorption.
3. Eradication of MARCoNS: Treatment of Multiple Antibiotic Resistant Coagulase Negative Staphylococci in the deep nasopharynx using compounded EDTA/colloidal silver nasal sprays.
