inflammation-post-4What Is Inflammation?

[dropcap]I[/dropcap]nflammation is our body’s necessary self-defense response and repair mechanism for these assaults:

1) injuries such as cuts, scrapes, sprains, broken bones, burns, insect bites, toxins; 2) invading organisms such as bacteria; and 3) allergens and food sensitivities such as gluten.

Inflammation can be immediate (acute) or persistent (chronic).

Acute inflammation is marked by increased blood flow, migration of white blood cells, and release of defensive proteins and chemicals to the site of injured tissue. Among these chemicals are free radicals in the immune response to injury that are beneficial yet require the activity of anti-oxidants such as vitamin E and vitamin C to control.

Free radicals are chemical particles containing one or more unpaired electrons, which may be part of the molecule. They cause the molecule to become highly reactive.1

The majority of this response takes place in the first 12 to 24 hours after the assault. The inflammatory process continues until all the damaged tissue or invading germs are removed (usually about 5 days).2

Chronic inflammation is marked by persistence weeks to months or longer after tissue damage. Note: high concentrations of free radicals generated in chronic inflammation may be important causes of damage to cell structures. The defensive activity of anti-oxidants such as vitamin E and vitamin C are required to remove free radicals.

Chronic inflammation increases the risk for systemic diseases such as type II diabetes, obesity, heart disease, high blood pressure, arthritis, osteoporosis, chronic fatigue, migraine, autoimmune disease, and vasculitis which may cause stroke, heart attack or deep vein thrombosis (DVT).

Importantly, chronic inflammation is a risk factor for the onset of cancer.3

Q: Are there blood tests available for detecting inflammation?

A: Yes. Your medical health practitioner can order either or both of the following blood tests that measure the amount of inflammation present although not the source of inflammation. Abnormal is an elevation in blood levels.

  1. C-reactive protein (CRP). This test measure C-reactive proteins that are released into the bloodstream within a few hours of tissue injury or infection. CRPs are cytokines called ‘acute phase reactants,’ meaning first on the scene. The CRP test is also useful to monitor treatment response and flare-ups of chronic inflammatory disease such as vasculitis, systemic lupus, and inflammatory bowel disease.
  2. Erythrocyte sedimentation rate (ESR or sed rate). This test measures the rate of fall of blood cells in a sample tube of blood. An increase in the rate of fall shows inflammation due to an increase of C-reactive proteins in the blood specimen. Alone or with the CRP test, the ESR is especially useful for monitoring inflammation of veins and arteries.

In regards to celiac disease, disappearance of blood antibody levels of tissue transglutaminase IgA (tTG-IgA) indicate that inflammation has also subsided. These antibodies should be checked at 3 months, 6 months if indicated, and one year after diagnosis to monitor healing. On the other hand, raised antibodies indicate that there is definitely ongoing inflammation in the small intestine.

In regards to non-celiac gluten sensitivity, disappearance of blood antibody levels of anti-gliadin IgA and IgG at 3 months, 6 months if indicated, and one year after diagnosis indicate that inflammation has also subsided. On the other hand, raised antibodies indicate that there is definitely ongoing inflammation caused by gluten within the body.

Vitamin D Deficiency

What Is Vitamin D?

[dropcap]V[/dropcap]itamin D is the principle regulator of calcium homeostasis (balance) in the body.  This “vitamin” is really a prohormone, meaning it acts like a hormone but is not. Vitamin D does, however, contain cholesterol in its molecular structure like steroid hormones.

The physiological importance of vitamin D encompasses much more than the regulation of bone metabolism although this is a mighty function.

Q: How does vitamin D regulate bone metabolism?

A: In regulation of bone metabolism, vitamin D works in three ways: 1) enables active absorption of calcium from the small intestine, 2) enhances reabsortion of calcium by the kidneys that would otherwise be excreted in urine, and 3) plays an active role in skeletal development and bone mineralization. Mineralization gives strength to living bone tissue.

Vitamin D interacts with receptors within cells to effect transcriptional changes in many cell types including those in gut, bone, breast, prostate, brain, skeletal muscle, and the immune system.1

In regards to the essential role of vitamin D in muscle tissue, it has been recently shown that vitamin D regulates both muscle function and structure of primary myofibers.2

Vitamin D is converted in the body to a molecule that is biologically active. The active form is 1,25-dihydroxyvitamin D, usually referred to as vitamin D3. About 80% comes from sun exposure and the remaining from food.

Vitamin D3 is synthesized in the skin from 7-dehydrocholesterol via photochemical reactions requiring UV light (sunlight). That is, light that contains energy from the sun is incorporated into molecules of  7-dehydrocholesterol in the underlying dermis of skin to make this vitamin. This is why inadequate exposure to sunlight contributes to vitamin D deficiency.

Blood concentration of 25(OH)D is the best indicator of vitamin D status. It reflects vitamin D produced in the skin and that obtained from food and supplements and has a fairly long circulating half-life of 15 days.3

neutrophilWhat Is Neutropenia?

[dropcap]N eutropenia  is a blood disorder characterized by presence of an abnormally low number of neutrophils.

Neutrophils are white blood cells (leukocytes) that serves as the primary defense against infections by destroying bacteria in the blood. 

Specfically, neutrophils are a type of granulocyte that contain granules filled with potent chemicals to break down the microbes they ingest. Some of these chemicals, such as histamine, also contribute to inflammation and allergy.

The process of eating and digesting microbes is called phagocytosis. Neutrophils are phagocytes.1

Q: How do neutrophils eat microbes?

A: Segmented neutrophils  are the mature phagocytes that migrate through tissues to destroy microbes and respond to inflammatory stimuli. Segmented neutrophils comprise 40-75 % of the peripheral leukocytes. They are usually 9 to 16 µm in diameter. The nuclear lobes, normally numbering from 2 to 5, may be spread out so that the connecting filaments are clearly visible, or the lobes may overlap or twist. The chromatin pattern is coarse and clumped. The cytoplasm is abundant with a few nonspecific granules and a full complement of rose-violet specific granules.1
