HOW TO TREAT CHRONIC INFLAMMATION

Resolution of inflammatory damage can return tissues to more youthful function. Researchers have identified natural pro-resolving mediators that help restore tissues injured by inflammation


Normal aging is often accompanied by increased systemic inflammation. This is evidenced by higher levels of inflammatory blood markers in elderly persons, as well as outward symptoms like persistent pain. Today’s consensus is that chronic inflammation is significantly involved with degenerative aging. Our ability to fully resolve stubborn inflammation diminishes in older age, thus worsening the systemic problems to which it contributes. Nutrients such as curcumin inhibit inflammation and reduce its severity.

Although inhibiting the onset of inflammation is important, emerging scientific research suggests this is only half of the equation. Resolution of inflammation may be as important as inhibition of inflammation. Resolution of inflammation is an active, critical process that demands factors called specialized pro-resolving mediators (SPMs) to optimally manage the inflammatory process. To this end, groundbreaking research has uncovered a method to resolve inflammation and return tissues to a healthier and more youthful function.

An Insidious Culprit As we age, the risk of degenerative disease increases. A central factor in age-associated illness is chronic inflammation. Many diseases of aging are closely linked with loss of youthful cellular function, and can be traced back to persistent and unresolved inflammatory reactions. Inflammation can be initiated and exacerbated in many ways including poor diet, environmental toxins, cigarette smoke, excess body weight, and aging.

Senescent cells that accumulate with age release compounds that promote and maintain an environment of chronic inflammation. Some inflammatory reactions, such as cartilage destruction in joints, lead to outward symptoms like pain.

CURCUMIN AND SPMS: A POWERFUL ONE-TWO PUNCH Specialized pro-resolving mediators (SPMs) are naturally occurring fatty acids. Inflammation is a unifying component of many of the diseases that afflict western civilizations. Nutrition therapy and in particular essential fatty acid (EFA) supplementation is one of the approaches that is currently in use for the treatment and management of many inflammatory conditions. The purpose of the present review is to discuss the recent literature in light of the discovery that essential fatty acids are converted by the body to a novel genus of lipid mediators, termed specialized proresolving mediators (SPM).


Recent findings The SPM genus is composed of four mediator families, the lipoxins resolvins, protectins and maresins. These molecules potently and stereoselectively promote the termination of inflammation, tissue repair, and regeneration. Recent studies suggest that in disease, SPM production becomes dysregulated giving rise to a status of failed resolution. Of note, several studies found that omega-3 fatty acid supplementation, at doses within the recommended daily allowance, led to increases in several SPM families that correlate with enhanced white blood cell responses in humans and reduced inflammation in mice.


What foods provide omega-3s?


Omega-3s are found naturally in some foods and are added to some fortified foods. You can get adequate amounts of omega-3s by eating a variety of foods, including the following:

  • Fish and other seafood (especially cold-water fatty fish, such as salmon, mackerel, tuna, herring, and sardines)

  • Nuts and seeds (such as flaxseed, chia seeds, and walnuts)

  • Plant oils (such as flaxseed oil, soybean oil, and canola oil)

  • Fortified foods (such as certain brands of eggs, yogurt, juices, milk, soy beverages

Nutrients like curcumin have also been shown to inhibit the initiation and reduce the severity of inflammation. SPMs, on the other hand, actively help resolve ongoing inflammation. By combining the use of nutrients like curcumin that help inhibit inflammation, and SPMs that help actively resolve ongoing inflammation, the detrimental effects of chronic inflammation can be mitigated. Over time chronic inflammation damages cells, organs, and blood vessels, which leads to loss of function and exacerbates risk of common, age-related health problems. WHAT YOU NEED TO KNOW

  • Chronic inflammation is a major contributor to almost every age-related disease and is a key cause of the aging process itself.

  • Long thought to be a passive process, the resolution of inflammation is now known to be an active process, requiring several fatty-acid-derived compounds known as specialized pro-resolving mediators (SPMs).

  • These SPMs remove dead and dying cells and debris left over from inflammation, restore a healthy balance of pro- and anti-inflammatory mediators, and renew tissues by initiating healing and regeneration.

  • In both animal and human models, aging is associated with dysfunctional SPM pathways, which in turn have been implicated in several age-related disorders. Higher SPM levels appear to be protective against these age-linked diseases.

Resolving Chronic Inflammation Some dietary components like curcumin and ginger, and drugs like NSAIDs, inhibit and/or reduce the severity of inflammation. They do this by blocking the onset (or induction) of inflammation by reducing the production of compounds that start the inflammatory process. Inhibiting the start of inflammation, however, is very different from facilitating the resolution of inflammation. In the past, the resolution of inflammation was believed to be a passive process. This was incorrect.

Emerging scientific advances demonstrate that the resolution of inflammation is a dynamic, active process requiring specialized factors that facilitate resolution. In a major finding, scientists have identified these specialized factors as lipid-based compounds that actively bring about the resolution of inflammation. These compounds are called specialized pro-resolving mediators or SPMs. Derived from specific types of polyunsaturated fatty acids, SPMs bind to specialized receptors on cells, organs, and blood vessels, actively helping to resolve the inflammatory process and allow the healing and regeneration of damaged tissues. The Power of Specialized Pro-Resolving Mediators SPMs (specialized pro-resolving mediators) fall into several inflammation-resolving sub-classes, and together, these SPMs can resolve inflammation and return tissues to normal function.

They accomplish this by their ability to do three vital tasks:

  • Remove. SPMs activate macrophages, which are immune system cells that remove the mess left behind from inflammation, including dead and dying cells and cellular debris. This cellular garbage must be cleaned up if healthy, surviving cells are to make a full recovery of function.

  • Restore. SPMs restore the healthy balance of inflammatory compounds in the tissue, reducing the pro-inflammatory mediators while increasing compounds that have anti-inflammatory activity.

  • Renew. They initiate and promote regeneration of tissues that have been disrupted or damaged by inflammation.

A few examples of the importance of SPMs in resolving inflammation include published studies showing: 1) Reduced or dysfunctional SPMs found in the brains of mice and humans with Alzheimer’s disease. 2) Defective SPM resolution linked to the progression of atherosclerotic plaque and therefore, cardiovascular disease. 3) Abnormalities of SPMs observed in conditions of insulin resistance like metabolic syndrome, as well as obesity.

ANTI-INFLAMMATORY COMPOUNDS + SPMS AS ADJUVANTS TO CANCER TREATMENT Surgery to remove malignant tumors and chemotherapy both aim to dramatically reduce the burden of cancer cells in the body. However, treatments such as these have the downside of stirring up inflammation in the area of the tumor, which can contribute to progression of the tumor and subsequent local recurrence or metastases. A recently published study has just validated the protective effect of anti-inflammatory therapies. In animal models of cancer, administration of an NSAID medication and resolvins (a group of specialized pro-resolving mediators) before surgery or chemotherapy, prevented treatment-induced tumor progression. These two treatments had synergistic effects, maximizing each other’s anti-cancer activities, and that led to superior long-term survival.

How to Increase SPM Activity Inspired by these findings, scientists sought to find a way to increase the presence of specialized pro-resolving mediators (SPMs) in the body, especially for aging individuals. Researchers identified the specific SPM fatty acids due to their distinct bioactivity and their ability to effectively resolve ongoing inflammation. These natural, polyunsaturated, fatty acids are stable precursors to a wide array of different types of SPMs.

SPMs help resolve inflammation and restore tissue function. They do this via mechanisms different from anti-inflammatory nutrients and drugs that inhibit inflammation. By providing these compounds to the body, the goal is to aid in the resolution of chronic inflammation, a critical component of any longevity regimen.

HARVARD MAGAZINE PUBLISHES ARTICLE ABOUT SPMS  A Harvard Magazine article published in 2019* noted the work of Dr. Charles Serhan and other scientists who are doing research on resolving and reversing inflammation. “In experiments with animals deficient in SPMs [specialized pro-resolving mediators], Serhan has shown that injecting SPMs amplifies the magnitude of the healing response, causing injuries to mend more quickly,” the author stated. He went on to say that, “The SPMs instead work in concert with the immune response.” They do this, according to Dr. Serhan, by stimulating macrophages, “to clear dead cells, debris, and bacteria. Then they bring the system back to homeostasis and begin to push the buttons to signal tissue regeneration.”

New SPM Studies The use of SPMs to treat disease and delay aging is cutting-edge science. Although the understanding of these natural fatty- acid compounds has been evolving for some time, the results of animal and human studies that demonstrate their impact on disease are relatively recent. In an animal model of osteoarthritis, supplementation with a specialized pro-resolving mediator (SPM) known as 17-HDHA, eliminated pain-linked behavior. In humans suffering from the same joint disease, higher blood levels of 17-HDHA correlated with less pain. These data suggest that systematically boosting levels of this SPM in the body may be a powerful tool to help resolve localized joint inflammation and pain.

Emerging research suggests that failure to effectively resolve inflammation is a key component in the development of age-related cognitive decline and Alzheimer’s-type dementia. Studies have identified dysfunctional SPM pathways in Alzheimer’s disease progression. In an animal model of dementia, the SPM resolution responses were blunted, the likely factor for the observed decline in brain function.

In humans, postmortem analysis of brain tissue from Alzheimer’s patients suggests that the inflammation resolution pathway is dysfunctional compared to healthy brain tissue. The mouth is a common site of chronic inflammation, even with adequate dental hygiene. This can contribute to halitosis (bad breath), damage to teeth and gums (periodontal disease), and even systemic inflammation.

In experimental models, topical oral treatment with SPM resolvins helped diminish inflammation and initiate regeneration of bone, gums, and teeth that had been damaged. Other studies suggest that abnormalities in SPM pathways play a role in chronic diseases that have inflammation as a component, including kidney failure, liver impairment, diabetes, obesity, atherosclerosis, and coronary heart disease.

INFLAMMATION RESOLUTION SPMs are specialized pro-resolving mediators. As their name implies, they don’t inhibit inflammation—they initiate the resolution of inflammation.

There is growing consensus that specialized pro-resolving mediators can be a potent longevity intervention. Scientists have identified and isolated three important SPMs that may help the body safely resolve chronic inflammation and thereby reduce the damage of aging. While SPMs can be used alone, by combining the use of curcumin (inhibit inflammation) and SPMs (resolve inflammation), inflammation can be effectively knocked out. Curcumin blocks the initiation and reduces the severity of inflammation. SPMs take the next step and resolve it, allowing tissues to restore themselves and function in a healthy manner.

Summary Inflammation that remains ongoing and unresolved inflicts damage that contributes to accelerated aging and most degenerative disorders. Nutrients like curcumin and ginger inhibit the onset of inflammation and help reduce the intensity of inflammation. Older individuals, however, often need to better resolve inflammation in order to return tissues to more youthful function. New research indicates that active resolution of inflammation can be accomplished with unique compounds known as specialized pro-resolving mediators (SPMs). Ongoing research indicates that these SPM compounds are critical for the resolution of active inflammation and the restoration of tissue health. Additional findings suggest that many age-related diseases are linked with insufficient or inadequate SPM activity.
