44 year old male presenting with history of sinus problems, mold sensitivity, allergies to cats and dogs, worsening and increasing food intolerance’s, vit D deficiency.
Has seen an NT before who suggested removing problem foods. Has removed so many foods, practically nothing left to eat that doesn’t cause some kind of problem.
Gut healing program in place but have a hunch that the underlying problem here is the mold exposure (historical and current). Suspect genetic susceptibility – mother has similar problems.
Any help much appreciated. Thank you.

Thank you for posting this question here. I am glad this man has sought out your support. I would agree with you given his history, both personal and family, that the issue with molds is likely an underlying culprit, and that there also is likely genetic susceptibility. There is an excellent mycotoxin testing panel that is now being offered by Great Plains Lab (https://tinyurl.com/y8xuaect) in the US, however, I did not see that it was available yet at Regenerus. You may want to call the company to find out more, and if the test will be available in the UK as well.
One of the issues with mycotoxins are that they can act as Nrf2 inhibitors. Ochratoxin A, one of the most common mycotoxins found in foods and water damaged houses, is known to be a Nrf2 inhibitor. This means that the body’s ability to regenerate glutathione and detoxify via other important detoxification enzymes and transporters is limited. Given subsequent insults of food sensitivities there also is likely intestinal permeability, contributing to a high systemic endotoxin load, which also blocks detoxification pathways.

Because of these things, it is important to support his glutathione levels and glutathione system, which is very important for detoxification. Glutathione is crucial for eliminating toxins from our cells, and many other enzymes, which are promoted by the transcription factor Nrf2 and promotor known as the antioxidant response element (ARE) are also necessary for detoxification. This includes the phase II enzymes glutathione S-transferase (GST), glutathione reductase (GSR), glutathione peroxidase (GPX), and nicotinamide adenine dinucleotide phosphate (NADPH), a reducing agent, as well as many of the Phase III transporters.

Depletion of glutathione can contribute to the development of allergies and a Th1/Th2 cytokine imbalance. Experimentally, Th1 dominance will shift to Th2 dominance (allergy/asthma) through depletion of intracellular glutathione, and introduction of glutathione will promote Th1 response. Glutathione can become depleted with continual exposure to toxins (ie a need for it) and our Nrf2 system which upregulates production of glutathione when needed becomes less capable with increasing age. Acetyl-Glutathione is a novel oral glutathione formulation that is stable in the stomach and gastrointestinal tract, well absorbed, and able to enter the cells directly and present to the cytosol for mitochondrial entry. Unlike other forms of glutathione, Acetyl-Glutathione tablets are odour-free and easy to take.

Although Nrf2 is maintained at a steady state level, it is constantly degraded in cells not experiencing stress. In cell cultures, Nrf2 has been shown to experience rapid degradation with a half-life of approximately 15 minutes, suggesting that in order to effectively increase its expression a sustained level of inducing substances, or stress, is necessary. Fortunately, we are aware of many natural substances and health-promoting practices which have evidence of inducing Nrf2 and thus our detoxification pathways and antioxidant defenses. This includes substances in items we consume like cruciferous vegetables (sulforaphane and 3,3′-diindolylmethane or DIM), tomatoes (lycopene) and green tea (epigallocatechin gallate, or EGCG). Although for healthy individuals without excessive toxin exposures these day-to-day activities or dietary habits may be adequate, this individual will likely need additional support.

Additional considerations are agents which support the reduction of histamine and improve the Th1/Th2 balance. This includes quercetin, vitamin C, and DIM. Quercetin is one substance which has been well studied for the reduction of a Th2 response as it inhibits histamine release and suppresses interleukin IL-4 production. It also has been shown to increase IFN-gamma and Th1 cytokine production. Because DIM also is an agent which supports the Nrf2 pathway you may want to try to introduce this first, possibly with vitamin C and glutathione directly.
