While the physician is responsible for patient care, patients can do at least some of the footwork, retrieving information so that the physician can make fully informed decisions.

The Marshall Protocol has been used in a variety of chronic inflammatory diseases. The gold standard for evaluating whether the MP is warranted is the therapeutic probeA brief trial of the Marshall Protocol to see if it will generate an immunopathological response. The "gold standard" for testing whether a patient is a good candidate for the MP., a brief trial of the Marshall Protocol to see if olmesartan medoxomil and pulsed low-dose minocycline will generate an immunopathological response. The results from a vitamin D metabolites test, while less definitive, may also suggest the presence of treatable condition. For an automated interpretation of the vitamin D metabolites, consult the Vitamin D Metabolite Calculator.

Other patient groups:

• pregnant/lactating women – Both olmesartanMedication taken regularly by patients on the Marshall Protocol for its ability to activate the Vitamin D Receptor. Also known by the trade name Benicar. and minocycline, the two mainstay medications of the MP, are contraindicated during pregnancy and while breastfeeding. Women of childbearing age on the MP should take adequate contraceptive precautions.
• children – Children with certain diseases and conditions have been treated with the MP. There are more than a dozen in the study cohort who are doing well. The FDA recently approved the use of olmesartan for hypertensive children ages 6-16.

Before commencing therapy, physicians and patients should familiarize themselves with the pre-MP checklist, which reviews the medications, eye protection, and possible lifestyle modifications necessary for treatment success and safety.

• Some patients' immunopathologyA temporary increase in disease symptoms experienced by Marshall Protocol patients that results from the release of cytokines and endotoxins as disease-causing bacteria are killed. may be difficult to control - Immunopathology in patients with severe forms of disease may be difficult to control. Physicians should help their patients learn the strategies for managing immunopathology. Knowing how to manage the MP independently on a day-to-day basis will serve patients well should an urgent situation occur. Patients should be urged to seek support from the Foundation's websites.
• Patients on the MP should not take nimesulide (Aulin / Mesulid / Nimed). It could cause bleeding. One death has been reported during its use.
• Rivaroxaban (Xarelto) increases the risk of bleeding and can cause serious or fatal bleeding. A specific antidote for rivaroxaban is not available.
• Do not give Telmisartan, it has an over strong action in suppressing the patient's ability to fight infection.
• Azithromycin is no longer regarded as safe, even in the small quantities formerly recommended for optional use while on MP
• For sicker patients, immunopathology can be physically and mentally challenging – Support from a knowledgeable doctor and family/friends becomes of paramount importance. Unless the patient has a good insight into IP and other inconveniences of the treatment, the patient should not start treatment.

The following is a summary of common medications that have the potential to interfere with the MP. A more complete list of medications is available in the Non-MP treatments article.

• antibacterials – Sulfusalazene, Plaquenil and Methotrexate are antimetabolite antibiotics with actions similar to Bactrim and may produce unwanted or uncontrolled immunopathology. They must be discontinued before starting the MP.
• antibiotics for acute infections – Olmesartan greatly potentiates the action of many antibiotics. Consequently, a severe or life-threatening immunopathological reactionA temporary increase in disease symptoms experiences by Marshall Protocol patients that results from the release of cytokines and endotoxins as disease-causing bacteria are killed. may result if non-MP antibiotics are prescribed for an acute infection. Olmesartan should not be withdrawn during these periods as it protects vital organs from damage by cytokinesAny of various protein molecules secreted by cells of the immune system that serve to regulate the immune system.. If a <html>non-MP antibiotic</html> is temporarily needed for an acute infection, please follow the instructions in the Notice for emergency medical personnel.
• anticoagulants – Olmesartan may profoundly affect the anticoagulant dosing requirement. It is absolutely essential to closely monitor any patient on anticoagulant therapy.
• antifungal agents – Medicines such as Diflucan and Lamisil are known to interfere with vitamin D metabolism and are generally contraindicated.
• antiviral agents – Antivirals may have profound effects on the immune system as well as a number of serious adverse effects. Routine use is generally contraindicated for MP patients.
• bisphosphonates – May cause calcium deposition into the soft tissues, reduced organ function and possible osteonecrosis of the jaw.
• calcium supplements – Should be avoided in the presence of hypercalciuria or hypercalcemia. Those without these conditions should generally consume 1000-1500 mg calcium daily, preferably from whole foods, but if this is not possible, calcium supplements without vitamin D are acceptable.
• corticosteroids – Therapy will not be effective while corticosteroidsA first-line treatment for a number of diseases. Corticosteroids work by slowing the innate immune response. This provides some patients with temporary symptom palliation but exacerbates the disease over the long-term by allowing chronic pathogens to proliferate. are suppressing the immune system. Begin or continue the gradual weaning process with the assistance of palliation from olmesartan. ACTH and cortisol production may be monitored to assess adrenal function.
• diuretics – Some diuretics including the thiazides are contraindicated for MP patients. If a diuretic is necessary, Lasix is preferred.
• folic acid (prescription or over the counter) – Folic acid makes it easier for occult bacteria to replicate and create new DNA. Consuming a balanced diet low in supplemental folic acid should provide adequate folic acid.
• hormonal replacement therapy (e.g. progesterone, estrogen and testosterone) – Because hormonal supplementation can interfere with the activity of many of the nuclear receptorsIntracellular receptor proteins that bind to hydrophobic signal molecules (such as steroid and thyroid hormones) or intracellular metabolites and are thus activated to bind to specific DNA sequences which affect transcription., hormonal supplementation is contraindicated. However, under certain circumstances, patients may continue hormone replacement therapy, until they are able to wean from it. See article on hormonal replacement therapy.
• interferon therapy – <html>Interferon</html> therapy is immunosuppressive, reducing in number both cytokines and immune cells.
• intravenous immunoglobulin (IVIG) – IVIG is derived from the blood of a pool of more than a hundred individuals, who could together harbor a large number of pathogens. There is a significant likelihood that pathogens from the blood of these people might spread to the recipient.
• nimesulide (Aulin / Mesulid / Nimed) may cause internal bleeding.
• rivaroxaban (Xarelto) increases the risk of bleeding and can cause serious or fatal bleeding. A specific antidote for rivaroxaban is not available.
• statins – Statins have a range of documented negative side effects and have been shown to exacerbate certain kinds of chronic disease. Some compete for the VDRThe Vitamin D Receptor. A nuclear receptor located throughout the body that plays a key role in the innate immune response. binding pocket. They are contraindicated.
• thyroid supplements – Need for these supplements may decline within a day or two of being on olmesartan alone. Monitor thyroid function closely and adjust the level of thyroid supplementation downward as needed.
• TNF-alpha blockers – <html>Tumor necrosis factor-alphaA cytokine critical for effective immune surveillance and is required for proper proliferation and function of immune cells. or TNF-alphaA cytokine critical for effective immune surveillance and is required for proper proliferation and function of immune cells. is a cytokineAny of various protein molecules secreted by cells of the immune system that serve to regulate the immune system. critical for effective immune surveillance. Anti-TNF drugsDrugs which interfere with the body's production of TNF-alpha - a cytokine necessary for recovery from infection, also known as TNF-alpha blockers, are drugs which interfere with the body's production of TNF-alpha.</html> While olmesartan also reduces levels of TNF-alpha, it does so to a lesser extent and in a manner less detrimental to immune function. Olmesartan blocks the initial generation of the substance rather than disabling free-floating TNF-alpha after the cytokine has been produced.

Patients on the MP must avoid all food and drink that contains supplemental vitamin D or high levels of naturally-occurring vitamin D. MP patients must avoid foods and drinks high in chlorogenic acidAn antioxidant and phenolic compound which in ways that are not yet fully clear can modulate and/or suppress the immune response – particularly coffee, concentrated juices, and supplements and multivitamins containing added folic acid. A low-carbohydrate, insulin-resistant diet is recommended for MP patients but is not required. Specific nutritional imbalances should in some cases be corrected, but this requires proper understanding of both the MP and the nutritional needs of the body by a health professional.

Patients on the MP often benefit from wearing glasses that block a broader spectrum of light and in many cases must cover their skin when in the sun. Further guidelines are available at the Knowledge Base articles on Eye protection and Skin protection.

Example of immunopathology – Patients on the MP, such as this 50-year-old male with ankylosing spondylitis, tend to experience temporary increase in markers of inflammationThe complex biological response of vascular tissues to harmful stimuli such as pathogens or damaged cells. It is a protective attempt by the organism to remove the injurious stimuli as well as initiate the healing process for the tissue..⁸⁾

Most patients on the MP experience temporary but well-defined increases in various markers of disease state and inflammation, consistent with an immunopathological response. It is helpful, but not necessary, to measure % lymphocytes, C-Reactive Protein, alkaline phosphatase, triglycerides, relevant “autoantibodies”, and serum ACE, to track systemic inflammation. Doctors may want to assess kidney function by testing creatinine or BUN and measure other indicators specific to each patient for a baseline and retest as appropriate. Some lab work – commonly HGB, HCT, eGFR, creatinine and BUN – may become temporarily abnormal, due to immunopathology reactions, until the inflammation resolves.

For example, a higher than usual BUN and creatinine is not an indication that olmesartan should be discontinued but a sign that immunopathology may be occurring in the kidneys or other nearby organs. In most cases where physicians have allowed such levels to remain temporarily out of range, BUN and creatinine have returned to range as microbial die-off in the kidneys subsides. We are not aware of any reports of MP patients needing dialysis, provided they remained on olmesartan.

If these markers indicate dysfunction sustained for more than several months, we advising using one or more methods to lower immunopathology levels.

There are two main vitamin D metabolites:

• 1,25-dihydroxyvitamin DPrimary biologically active vitamin D hormone. Activates the vitamin D nuclear receptor. Produced by hydroxylation of 25-D. Also known as 1,25-dihydroxycholecalciferol, 1,25-hydroxyvitamin D and calcitirol. (1,25-DPrimary biologically active vitamin D hormone. Activates the vitamin D nuclear receptor. Produced by hydroxylation of 25-D. Also known as 1,25-dihydroxycholecalciferol, 1,25-hydroxyvitamin D and calcitirol.) – The presence of high levels of this active vitamin D hormone in patients suggests an ongoing chronic inflammatory disease process.⁹⁾ However, the absence of elevated levels does not mean a patient cannot benefit from treatment particularly since non-MP therapies such as TNF-alpha blockers and other unknown drugs and interventions can alter 1,25-D levels. Whenever possible, use the lab Quest Diagnostics. Quest has recently ceased to routinely freeze the 1,25-D samples, as we find necessary. However, the 1,25-D sample will not be frozen unless the patient specifically asks.
• 25-hydroxyvitamin D (25-DThe vitamin D metabolite widely (and erroneously) considered best indicator of vitamin D "deficiency." Inactivates the Vitamin D Nuclear Receptor. Produced by hydroxylation of vitamin D3 in the liver.) – Unlike 1,25-D, serum samples of 25-D need not be frozen. 25-D is a secosteroid with possible immunosuppressive effects.¹⁰⁾ Thus, patients on the MP restrict consumption of vitamin D in order to reduce their 25-D at or below 12 ng/ml. Levels of 25-D should be tested every 6-12 months. Be aware that as 25-D levels fall, immunopathology may increase, sometimes dramatically.

If the vitamin D metabolite tests do not indicate Th1 inflammationThe complex biological response of vascular tissues to harmful stimuli such as pathogens or damaged cells. It is a protective attempt by the organism to remove the injurious stimuli as well as initiate the healing process for the tissue. but clinical observation suggests otherwise, a short course of the MP (1 to 2 months) should be used as a therapeutic probe. A longer time period may be needed if 25-D levels remain high, as a therapeutic probe is often not effective unless 25-D levels fall below 25 ng/ml.

Benicar is a weak hypotensive. Image: FDA label for Benicar

Consult the Vitamin D Metabolite Calculator for suggestions on interpreting this lab data.

The primary indication for olmesartan (Benicar)Medication taken regularly by patients on the Marshall Protocol for its ability to activate the Vitamin D Receptor. is as a mild hypotensive drug. As one can see from the FDA label for Benicar (right), the dose response curve for Benicar is asymptotic, with higher dosages of the drug having incrementally smaller decreases in blood pressure. For example, the difference between 40mg and 80mg of olmesartan results in a decrease of no more than 1mm Hg.

A decline in systolic pressure greater than 15mm Hg of mercury cannot solely be due to olmesartan’s hypotensive action. Instead, the drop is also likely due to the disease processes itself.

For example, the widespread destruction of bacteria and human cells infected by bacteria can lower blood pressure. Although this isn’t true of all bacterial forms, when some forms of bacteria are destroyed, they release endotoxins,¹¹⁾ the bioavailability of which can lead to a steep decline in blood pressure.¹²⁾

If a patient suffers low blood pressure before the MP, low blood pressure will return as a symptom of immunopathology while on the MP. In most cases, we find as bacterial die-off subsides, blood pressure levels begin to return to a normal range even as patients continue to take the same dose of olmesartan.

Thus, medications that raise blood pressure, such as fludrocortisone and dopamine, are contraindicated, both because they would do nothing to slow bacterial die-off and because they may have deleterious effects on immune function.

For the purposes of the MP, olmesartan has two primary actions: it reduces inflammation by blocking the Nuclear Factor-kappaB cytokine pathway and it is an agonist of the Vitamin D ReceptorA nuclear receptor located throughout the body that plays a key role in the innate immune response. (VDR). As a VDR agonistA substance such as olmesartan (Benicar) or 1,25-D which activates the Vitamin D Receptor and transcribes the genes necessary for a proper innate immune response., olmesartan activates the innate immune responseThe body's first line of defense against intracellular and other pathogens. According to the Marshall Pathogenesis the innate immune system becomes disabled as patients develop chronic disease.. Research supports the safety of the doses used by MP patients. Olmesartan has minimal interactions with other drugs and is one of the safest drugs on the market.

The half-life of olmesartan is reported to be 13 hours. This would imply that the drug would remain active during that period of time, however, we have found that in sick patients, olmesartan is most effective when administered every 4-6 hours, with a maximum of every 8 hours. This may be due to the fact that some intracellular infections (notably Shigella), upregulate activity of the caspases, which are proteases that cleave the VDR.¹³⁾ When the VDR is broken apart by the caspases, it is highly likely that any ligands bound to it (such as olmesartan) would stay bound to the fragments of the protein. Therefore, a VDR agonist would be effective over shorter periods of time in patients with infected cells.

The U.S. Food and Drug Administration has set no safe limit for olmesartan medoxomil (Benicar), as no dose-related adverse events have been identified to this point. FDA post-marketing-experience has shown that Olmesartan has one of the safest profiles of any drug on the market. Note that this does not apply to the combination drugs, such as Benicar HCT, which contains a thiazide and is harmful, and should never be used with an MP dosing schedule.

The label for olmesartan medoxomil states that the drug is well-tolerated. Adverse events were similar to those experienced by the placebo group. Adverse events were generally “mild, transient and not related to dose.” The frequency of adverse events also had no relationship to the dose of olmesartan.

A 2001 study published in the Journal of of Pharmacology found olmesartan to be safe and well tolerated at dosages of up to 160 mg/day.¹⁴⁾

In placebo-controlled trials, the only side effect that occurred in more than 1 percent of olmesartan-treated patients vs. placebo-treated patients was dizziness (3 percent vs. 1 percent).¹⁵⁾

The relevant Knowledge Base article reviews the safety profile of olmesartan/Benicar in greater detail.

The Marshall Protocol has historically emphasized a role for antibiotics. However, as our understanding of the recovery process has progressed, this emphasis has been greatly minimized. This change is gradually being reflected in the guidance available here. In the event of any uncertainty, patients or their physicians should seek guidance on the Protocol forums.

1. Test vitamin D metabolites – Follow the vitamin D metabolites testing instructions. Remind the drawing lab that the 1,25-D sample must be clotted no more than 30 minutes before centrifuge and the resulting serum must be frozen for shipment. Consult the Vitamin D Metabolite Calculator for suggestions on interpreting this lab data.
2. Restrict dietary vitamin D intake – Patient must restrict all supplements and foods high in Vitamin D. It is recommended that, over the course of treatment, the patient reduce 25-D to the therapeutic target of approximately less than 12 ng/ml. Retest 25-D periodically to make sure 25-D is dropping toward the lower end of the therapeutic range. Many MP patients have kept their 25-D below 5 ng/ml for many years, without any adverse effect.
3. For patients taking corticosteroids, begin olmesartan – Corticosteroids are contraindicated for MP patients. Before weaning them, patients should first begin olmesartan (see below), which can greatly relieve withdrawal symptoms and help ensure weaning success. It is recommended that olmesartan be started a week or two before beginning to wean. See the weaning guidelines for detailed instructions.
4. Withdraw or begin to wean contraindicated therapies
5. Avoid EMF Mobile phone brain tumor avoid immune suppression
6. If necessary, avoid light – If necessary to avoid the symptoms of photosensitivityAbnormal sensitivity to sunlight and bright lights. Also referred to as "sun flare" or "light flare.", patients should avoid outdoor light and bright indoor lights by staying indoors as much as possible, using heavy curtains or window shades, and covering up well whenever venturing outside during daylight hours. Patients may also need to protect their eyes from both outdoor and indoor light.
7. Begin olmesartan – Commence therapy by prescribing 40mg pure olmesartan medoxomil every six hours (e.g.: 6am, noon, 6pm, midnight) to interrupt the inflammatory cycle and reduce the severity of potential immunopathology. Our observations suggest that olmesartan medoxomil is the only angiotensin receptor blocker (ARBA drug which is an angiotensin receptor blocker. One of the ARBs is olmesartan (Benicar). Not all ARBs activate the Vitamin D Receptor.) that activates the patient’s innate immune system. “No substitutions” should be written on the prescription. Avoid any combination formulation such as Benicar hydrochlorothiazide (Benicar HCT). Because patients often begin to feel worse when decreasing light and/or vitamin D, olmesartan should be prescribed concurrently with the previous steps, so that it can palliate any resulting immunopathology while the 25-D levels are decreasing. Patients should keep several weeks’ supply of olmesartan in reserve to use in case it is needed to treat intolerable immunopathologyAn unbearable or unsafe severity of bacterial die-off reaction..
8. Wait for patient to stabilize on olmesartan – It usually takes a month or two to stabilize symptoms on olmesartan alone. Some patients may need more time. Depending on the patient's bacterial load and a host of other factors, some patients initially feel better on olmesartan, some worse, and some don't experience any change. All three reactions are normal. A partial list of typical immunopathology symptoms includes: depression, irritability, mania, paranoia, fatigue, muscle weakness, rash, headache, photosensitivity, pain anywhere, numbness, nausea, diarrhea, constipation, ringing in the ears, toothache, sinus congestion, nasal stuffiness, fever/chills, flu-like body ache, cough, sleep disturbances and “brain fogThe loss of intellectual functions such as reasoning; memory loss; and other neurological abilities that is severe enough to interfere with daily functioning..”
9. There may be benefit from olmesartan every four hours - the immunostimulative and palliative effects of olmesartan are believed to be maximal at four-hourly dosing. Once the patient has stabilized, the frequency should be gradually increased to every four hours, over several weeks, or in accordance with the patient's ability to tolerate any increases in immunopathology that may result. (Some patients will actually feel better at the higher frequency.)

ARF has prepared a Notice for emergency medical personnel treating a Marshall Protocol patient. Important points from that document include the following:

• Do not withdraw olmesartan – In a critical care situation, it is essential to continue oral olmesartan, even in the presence of hypotension, as abrupt withdrawal can be life-threatening. Along with routine lifesaving procedures, it is essential to continue oral olmesartan 40mg dosing every four hours, with 20mg SL p.r.n., until symptoms subside - even if an NG tube is necessary. If B/P is extremely low (mean arterial pressure <55), continue olmesartan as above and increase fluid volume with 0.9 NS or packed red cells.
• antibiotics – We strongly recommend patients not be treated with MP antibiotics for an acute infection. Unless patients have reached a late stage of the treatment these antibiotics may greatly increase immunopathology as they leave a patient's system. Cephalosporins, Claforin, and the macrolide Biaxin are usually tolerated. Fluoroquinolone antibiotics may be tolerated although instances of tendon damage have been reported; the patient should be advised of the FDA black-box warnings.
• corticosteroids – Do not give corticosteroids in any form or by any route (injected, inhaled, oral or IV) as they will lead to metabolic instability.
• Do not give nimesulide (Aulin / Mesulid / Nimed). It could cause bleeding.
• Rivaroxaban (Xarelto) increases the risk of bleeding and can cause serious or fatal bleeding. A specific antidote for rivaroxaban is not available.
• epinephrine or norepinephrine – Adverse reactions may occur if epinephrine or norepinephrine is used to raise B/P or treat anaphylaxis. Use epinephrine and norepinephrine only for cardiac arrest. Local anesthetics containing epinephrine may cause adverse events (tachycardia, psychosis), and the epinephrine may hinder anesthesia.

For the details of these recommendations, please consult the Notice for emergency medical personnel.

In an emergency, physicians may call Trevor Marshall at 1-805-492-3693.

Olmesartan will need to be weaned very gradually. Note that the immune response may remain activated for a period of time even after discontinuing olmesartan. Patients who stop olmesartan are terminating their recovery.
