What Is Primary Addison’s Disease?

Addison’s disease is an autoimmune destruction of the adrenal glands by autoantibodies that target the adrenal cortex, or outer part of these glands, and is characterized by a slow progressive failure of the adrenal glands to adequately produce its steroid hormones.

Symptoms of adrenal fatigue or failure may not develop until the majority of adrenal tissue is destroyed. When untreated, progression leads to coma, called Addisonian crisis, which is a medical emergency.

There are two adrenal glands each located on top of a kidney and enclosed in a connective tissue capsule. Each is a small, triangular shape that is made of two parts: the outer region and the inner region.

The inner region, called the adrenal medulla, produces epinephrine and norepinephrine chemicals that are needed to deal with stress.

The outer region, called the adrenal cortex, produces adrenocortical (steroid) hormones and releases them into the bloodstream in response to pituitary stimulating hormone from the brain.

Q: What is the function of steroid hormones produced by the adrenal glands?

A: Functions of the three steroid hormones produced by the adrenal glands are:

  1. Glucocorticoids restrain inflammation and metabolism of carbohydrates, fats and proteins to maintain a normal glucose blood level. The major glucocorticoid is hydrocortisone.
  2. Mineralocorticoids regulate the retention and excretion of fluids and electrolytes by the kidneys. The most important mineralocorticoid is aldosterone.
  3. Androgen (testosterone) is a male sex hormone.

Secondary adrenal insufficiency may develop from other causes that are not immune related such as chronic infections, tumor, and medications.

What Are Anti-Endomysium Antibodies?

A nti-endomysium antibodies (EmA) are connective tissue autoantibodies produced in persons who have inherited the genes for celiac disease, an autoimmune disease, and are reacting to gluten in their diet.

Autoantibodies are abnormal in that they attack the body’s own tissue.

Q: What is endomysium?

A: Endomysium is the delicate connective tissue that surrounds individual muscle fibers. The autoantigen, or target, that stimulates the autoimmune response is the naturally occuring enzyme in endomysium called tissue transglutaminase (tTG), or more specifically tranglutaminase-2 (TG2). Anti-tissue transglutaminase antibodies recognize the same antigen as EmA, from which they differ in terms of detection method.

Anti-endomysium antibodies (EmA) are tested by the indirect immunofluorescence method and directed against “reticulin-like” fibres in connective tissue around smooth muscle fibres in the esophagus, liver, stomach, and bladder of monkeys, in the sections of the jejunum and kidneys of rats and in sections of the human umbilical cord. In comparison, for the determination of anti-tissue transglutaminase IgA and IgG antibodies, ELISA with human extractive or recombinant transglutaminase is recommended.1

EmA‐binding patterns in serum samples from patients with celiac disease have proved to be exclusively TG2‐targeted and the correlation between EmA and TG2 antibodies is therefore good. Evidence shows that celiac autoantibodies are produced in the small‐bowel mucosa.2

Hashimoto’s Disease (Autoimmune Thyroiditis Causing Hypothyroidism)

hypoglycemia symptom of celiac disease and glutenWhat Is Hypoglycemia?

Hypoglycemia means the level of glucose within cells is too low to meet metabolic needs of the body for this essential sugar.

Q: What are the metabolic needs for glucose?

A: Glucose is the most important simple sugar in human metabolism mainly because it is the primary source of energy for most cells of the body.

Energy contained in the glucose molecule is obtained by the body from its reaction with oxygen (oxidation). This oxidation reaction occurs in power producing mitochondria structures that are located within cells.1

Hypoglycemia is characterized by alterations in neurologic, metabolic and muscular functions:

  1. Neurologic function because brain tissue is particularly dependent on glucose for energy,
  2. Metabolic function of glucose-dependent tissues which include red blood cells, white blood cells, bone marrow, eye, inner heart of the kidney, and peripheral nerves because these tissues cannot metabolize fatty acids as an alternate source of energy, and
  3. Muscle function because muscle cells continually require glucose for energy production.

Glucose is made available to cells through the regulating action of insulin, a hormone produced by specialized cells located on the surface of the pancreas.

What Are Elevated Liver Enzymes?

H ypertransaminasemia is a chronic condition of elevated blood liver transaminase enzymes, commonly called “liver enzymes,” that signifies hepatocellular (liver) injury.

Q: What are serum transaminases?

A: Transaminases are the liver enzymes ALT and AST. ALT is the abbreviation for alanine aminotransferase enzyme and AST is the abbreviation for aspartate aminotransferase enzyme.

Transaminases are commonly measured in routine blood tests to determine liver function. Elevated ALT and AST transaminases  indicate inflammation of the liver. Other specific tests must follow to determine the cause of inflammation.

What Is Melanoma?

M elanoma is a cutaneous malignancy with rapid invasion and metastasis to other parts of the body.

Melanoma is characterized by growth from melanocytes appearing as a new mole or enlarging from an exisiting mole, changing shape, size or color.

Melanocytes are cells found in the lower epidermis layer that produce melanin, or pigment, that colors the skin.

Muscle pain in celiac disease and gluten sensitivityWhat Is Chronic Muscle Pain And Tenderness?

M uscle pain and tenderness, also called myalgia, is a disorder of muscle tissue.

Muscle pain that is ongoing or chronic can result from a variety of disorders, infections, overuse, injury, as an unwanted effect of certain medications, toxic substances, celiac disease, and certain nutritional deficiencies.

What Is Tetany?

T etany is a painful feature of low blood calcium or low blood magnesium causing hyperexcitability of all nerves which in turn stimulates involuntary sudden, intermittent and repetitious tonic spasms of muscles. Tonic spasms are steady rather than jerky.

Causes include low function of the parathyroid glands which regulate calcium blood levels, vitamin D deficiency which inhibits calcium absorption from the gut that leads to calcium deficiency, and alkalosis.

In alkalosis, the chemical pH (acid/alkaline measure) of blood is too high, or alkaline, which inhibits adequate free calcium ions from being available for cell use.

Q: Why do low blood levels of calcium or magnesium cause muscles to spasm?

A: Calcium controls the readiness of muscle to respond to nerve stimulation. In muscle action, calcium and magnesium are minerals that oppose each other. Calcium allows a muscle to contract while magnesium allows it to relax. Inadequate levels of these opposing minerals affect the ability of muscles to properly function.

A simple test for tetany is called Trouseau’s named after the doctor who developed it. A blood pressure cuff is placed on an upper arm as usual and pumped up to a pressure sufficient to stop blood flow.  The pressure must be held for 3 minutes. A positive result is shown in the above photo of carpopedal spasm: the wrist and hand flexes inward while the fingers extend (opposite of wrist and hand) and the thumb goes against the palm.

What Are White Spots And White Bands In Nails?

W hite spots in the nails is a feature of zinc deficiency and white bands signify protein deficiency characterized by abnormal appearance anywhere in one or more nails.

White spots and bands can appear separately or together in nails. There may be just one mark or many marks depending on the level of deficiency.

Q: What part of the nail is affected by zinc and/or protein deficiency?

A: Zinc and protein deficiencies affect the nail plate.

The nail plate is the hard keratin cover of the finger tip and toe tip, simply called “the nail.” The nail plate is produced by the living nail tissue at its base. Here is an illustration of the parts that make up a fingernail:
