Hypocalcemia (Low Blood Calcium)

hypocalcemia celiac disease gluten symptomWhat Is Hypocalcemia?

Hypocalcemia, or low plasma calcium, means the level of calcium in blood is too low to meet metabolic needs of the body for calcium.

Low blood calcium is characterized by bone and tooth demineralization (loss of calcium causing weak teeth and fragile bones), and these impaired functions: nerve conduction, muscle contraction, blood clotting, blood pressure regulation, glycogen to glucose conversion, many hormone actions, many enzyme activities, and acetylcholine production.

Q: Where is calcium found in the body?

A: Calcium is the most abundant mineral in the body, with 99% residing in bones and teeth where it constitutes 40% of skeletal bone weight along with 45% phosphorus. As a component of bone (hard tissue), calcium fulfills a structural role to maintain body size and act as attachments for musculoskeletal tissues. The remaining 1% of calcium is present in blood and soft tissues.

Calcium levels in the blood are maintained within very strict limits by dietary intake, hormonal regulation by the parathyroid gland and a rapidly exchangeable pool in bone tissue.

Neutropenia 

neutrophilWhat Is Neutropenia?

Neutropenia  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

Paleness and Tendon Problem: Symptoms of Hypocupremia.

What Is Hypocupremia?

Hypocupremia, or low plasma copper, means the level of copper is too low to meet metabolic needs of the body for copper and is characterized by these many features:

  1. Impaired energy production causing weakness.
  2. Impaired ability as part of an enzyme to oxidize vitamin C which is required to breakdown histamine.
  3. Faulty blood cell formation and instability of blood cell membranes causing anemia, shortened life span of neutrophils causing susceptibility to infection, faulty platelet formation causing impaired blood clotting.
  4. Faulty elastin formation causing weak blood vessels.
  5. Poor collagen and connective tissue strength causing joint and tendon problems and weak bones causing deformities, faulty bone mineralization causing fragile bones.
  6. Loss of proprioception causing ataxia.
  7. Loss of pigmentation of hair and skin.
  8. Impaired thyroid function.
  9. Impaired adrenalin production.

Untreated, copper deficiency can advance to brain degeneration. Failure to make normal blood cells can result in death.

What Is Transient Erythroblastopenia?

Transient erythroblastopenia is a rare disorder of red blood cell formation characterized by brief, reversible disappearance of erythroblasts (red blood cell precursors) in the bone marrow of children.

Q: What do the red blood cells look like?

A: Circulating red blood cells appear normal so that the anemia which develops is a normocytic (normal cellular) anemia in contrast to microcytic (small cell) anemia in iron deficiency or macrocytic (large cell) anemia in vitamin B12 or folic acid deficiency.

Because new red blood cells are failing to mature, packed red blood cell transfusions may be necessary in severe anemia.

In adults, this disorder is called pure red blood cell anemia.

Hypoglycemia (Low Blood Sugar)

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 Is Easy Bruising?

Ecchymosis, or easy bruising, is a feature of impaired secondary hemostasis (blood clotting) characterized by subcutaneous bleeding (under the skin) in response to light trauma.

Q: What causes easy bruising?

A: Easy bruising is the direct result of vitamin K deficiency that develops from inadequate diet, malabsorption, dysbiosis, and vitamin K depleting medications.

What Is Hypophosphatemia?

Hypophosphatemia 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.

Macroamylasemia

Depiction of pancreatic amylase molecule.

What Is Macroamylasemia?

Macroamylasemia 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 Macrolipasemia?

Macrolipasemia 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

Macrocytosis

Comparison of normoblast and megaloblastWhat Is Macrocytosis?

Macrocytosis is a blood cell disorder characterized by altered blood cell formation that results in abnormally large erythrocytes (red blood cells) circulating in the bloodstream.

The mean corpuscular volume (MCV), which is a measure of the size of red blood cells in the bloodstream, is greater than 100 fL as shown in a complete blood count (CBC) laboratory analysis report.

Macrocytosis produces macrocytic anemias that are classified as megaloblastic or non-megaloblastic:

  1. Megaloblastic anemias result from disorders of DNA synthesis of red blood cell precursors (megaloblasts) in bone marrow due to B vitamin deficiency demonstrated by macro-ovalocytes and hypersegmented neutrophils.1
  2. Non-megaloblastic anemias are or those caused primarily by alcoholism, liver disease and hypothyroidism.2
