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.

Systemic Lupus Erythematosus 

bruiseWhat Is Hypoprothrombinemia?

[dropcap]H ypoprothrombinemia is a deficiency of prothrombin (clotting factor II) in the blood that is characterized by impaired hemostasis in response to trauma or a laceration.

Q: What is hemostasis and how is it altered by a deficiency of prothrombin?

A: Hemostasis encompasses the tightly regulated processes of blood clotting, platelet activation, and blood vessel repair.1

Prothrombin is a protein clotting factor present in blood that is involved in the first part of hemostasis, which is blood clotting or coagulation. Vitamin K is required for prothrombin production.

When a laceration or wound is sustained, prothrombin is converted to the enzyme thrombin. Thrombin in turn acts on fibrinogen to convert it to fibrin which then forms the framework of a clot to stop bleeding. Deficiency of prothrombin prevents this series of events and bleeding is not properly stopped.

After the clotting process of hemostasis would come the second part, platelet activation. Eventually, coagulation and platelet activation are switched off by blood-borne inhibitors.

What Is Hemochromatosis?

[dropcap]H emochromatosis, also called iron overload liver disease, is a common inherited disease in the Caucasian population that is characterized by increased iron deposition within the tissues (overload) associated with injury to them.

Hemochromatosis is an autosomal recessive disease, meaning a pair of abnormal genes are inherited from each parent. Parents are unaffected because they carry only one gene.

Q: Where is iron deposited?

A: In hemochromatosis, more iron is absorbed from the small intestine than is needed by the body. Subsequently, because the body has no satisfactory means to release iron overload, excess iron is deposited in various organs such as the liver causing cirrhosis, joints causing arthritis, and the pancreas causing diabetes mellitus.1

Consumption of alcoholic drinks with food should be avoided because alcohol increases leaky gut and greatly increases the absorption of iron. On the flip side, eggs and foods containing calcium such as milk and cheese are beneficial for hemochromatosis because they impair the absorption of iron. Another iron inhibitor is food that contains phytic acid which includes the bran and outer layer of grains, seeds, nuts, peas, beans, and lentils.

Iron overloading, as measured by a random (non-fasting) elevated transferrin saturation value, is estimated to occur in 1 to 6 people per 100 in the United States according to the CDC (Center for Disease Control and Prevention). Too much iron increases the risk for metabolic syndrome, type 2 diabetes mellitus, cancer, liver disease, and osteoporosis.

Medical treatment to remove excess iron from the body uses phlebotomy that draws blood through a vein and/or certain injectable drugs (deferoxamine and deferairox) that bind to iron.

What Is Macrolipasemia?

[dropcap]M acrolipasemia is a rare enzyme disorder characterized by altered molecules of lipase, a pancreatic enzyme needed to digest fats, that are abnormally bound with serum antibody proteins. These antibodies are commonly immunoglobulin G (IgG) and/or less likely immunoglobulin A (IgA).

Q: What happens when lipase is bound to immunoglobulins (IgA and/or IgG)?

A: The resulting molecule is too large to be filtered by the kidneys and excreted in the urine, consequently these abnormal molecules build up in the plasma causing sustained elevation of lipase levels called macrolipasemia.

Macrolipasemia occurs with or without macroamylasemia, which is the binding of immunoglobulin A and/or G to amylase, a pancreatic enzyme needed to digest starches.1

What Is Macroamylasemia?

[dropcap]M acroamylasemia is an acquired enzyme disorder that causes elevated levels of the enzyme amylase (hyperamylasaemia) in the bloodstream. It is characterized by altered amylase molecules that have become abnormally bound with plasma proteins in the bloodstream, commonly IgG (immunoglobulin G) and/or IgA (immunoglobulin A).

The resulting molecule is too large to be properly filtered by the kidneys and excreted in the urine as would be normal unbound amylase, causing sustained elevation of amylase levels in the plasma.

With normal kidney function, a hyperamylasemia without an increase in urine amylase suggests the diagnosis of macroamylasemia, and is confirmed by identifying the macromolecular components.1

Amylase is a an enzyme produced by the pancreas and the parotid glands to digest starch in the diet. Comparatively small amounts are also produced by other organs.

Q: How do the pancreas and parotid glands deliver their amylase for digestion of starch?

A: The parotid glands deliver their amylase into the mouth. The action of amylase in the mouth starts the breakdown of starch as it is chewed and moistened with saliva.

After the starchy food is liquified in the stomach, the mass empties into the duodenum. Here pancreatic amylase is delivered through the common bile duct into the duodenum where it turns starch into maltose sugar. The next step to final digestion of starch is carried out by enzymes in the small intestinal lining that split maltose into its component sugar which is glucose.

Glucose is a simple sugar that can be absorbed into the bloodstream for use in the body. Humans cannot live without adequate glucose.

Distinquishing macroamylasemia from hyperamylasemia due to pancreatic disease is necessary to prevent needless treatment and investigation for pancreatitis.2

What Is Immune Thrombocytopenic Purpura?

[dropcap]I mmune thrombocytopenia purpura (ITP), formerly called idiopathic, is an immune mediated bleeding disorder characterized by destruction of circulating platelets (thrombocytes) by autoantibodies in the presence of normal bone marrow and without other conditions that cause bleeding problems including many medications.

Q: How do autoantibodies destroy platelets?

A: Autoantibodies bind to normal platelet surface antigens (targets) which forms a complex that is cleared from blood by the reticuloendothelial system. Consequently, this condition results in an abnormal decrease in the number of platelets circulating in blood plasma.

Platelets are cells that are needed to stop bleeding. A normal platelet count is in the range of 150,000 to 450,000. With ITP, the platelet count is less than 100,000. By the time significant bleeding occurs, the patient may have a platelet count of less than 10,000. The lower the platelet count, the greater the risk of bleeding. 

Because of inability of blood to properly clot due to lack of sufficient platelets, a distinctive purplish rash develops under the skin from blood leakage and an appearance of many small red spots of varying size can cover the skin. Depending on the number of platelets, there may be minimal to extensive bleeding in various parts of the body.  Bleeding in the brain is the worst complication, causing death in approximately 1% of affected children and 5% of affected adults.

Immune thrombocytopenic purpura is common in childhood, on average 50 cases per 1,000,000 per year with same incidence in boys as girls. It may follow a viral infection or immunization and is caused by an inappropriate response of the immune system to cross react against the body’s platelets.1

The incidence of immune thrombocytopenic purpura in adults is approximately 66 cases per 1,000,000 per year.  Older persons and persons with a previous history of hemorrhage are at increased risk of severe bleeding in adult ITP.  

Spontaneous remission occurs in most children (80%).  Remission in adults usually requires treatment.

What Is Hypophosphatemia?

[dropcap]H ypophosphatemia means the level of phosphates in the bloodstream is too low to meet metabolic needs of the body for this mineral.

Q: How important is phosphorus in metabolism?

A: Phosphorus is crucial to  life, being present in every cell of the body and constitutes 45% of skeletal bone weight along with 40% calcium needed to support the body as a framework.

A low blood phosphate level is characterized by alterations in blood acid-alkaline balance and serious neuromuscular, hematologic, renal, skeletal, and dental abnormalities.

Symptoms result primarily from decreased production of adenosine triphosphate (ATP), the main energy source in cells, and phosphocreatine, a secondary energy source for muscle contraction.

  • Acute phosphorus deficiency may precipitate rhabdomyolysis which is destruction of muscle.
  • Nervous system dysfunction is observed in severe hypophosphatemia.
  • Chronic phosphorus deficiency causes proximal myopathy (upper arms and thighs).1
  • Severe phosphorus deficiency has widespread and ultimately fatal consequences.

hypomagnesemiaWhat Is Hypomagnesemia?

[dropcap]H ypomagnesemia means the level of magnesium in the bloodstream is too low to meet metabolic needs of the body for this mineral.

Q: What are the metabolic needs of the body for magnesium?

A: The metabolic needs of the body for magnesium are numerous which gives rise to very many distressing symptoms when this mineral is deficient.

A major function of magnesium is to stabilize the structure of an enzyme called adenosine triphosphate (ATP) within cells for the production of energy. In the brain, magnesium plays important roles in all the major metabolisms such as oxidation-reduction and regulation of ions (charged minerals).1

bloodvialWhat Is Prolonged Prothrombin Time?

[dropcap]P rolonged prothrombin time (PT) is a laboratory blood test result showing that blood clots too slowly which makes the patient subject to abnormal bleeding.

Q: What does the prothrombin time (PT) test measure?

A: The prothrombin test measures the clotting ability of blood protein factors I, II (prothrombin), V, VII, and X. If any of these factors are too low, it takes longer than normal for the blood to clot. Prothrombin is a vitamin K dependent factor meaning a deficiency of vitamin K will cause low prothrombin.

Blood is drawn into a blood collection tube with a light blue stopper which has a buffering additive. Tubes must be completely filled.
