What Is Systemic Lupus Erythematosus?

[dropcap]S[/dropcap]ystemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease that is characterized by involvement of multiple organs due to the production of antibodies to components of the cell nucleus.1 SLE has an unpredictable course of acute flare-ups and remissions.

Severity depends on the extent of organs affected with skin and nail involvement, called discoid lupus, being the least serious and inflammmation of the kidney, called lupus nephritis, being the worst.

Nevetheless, a classic presentation is development of a rash over the cheeks and nose that resembles a butterfy with wings spread hence the name “butterfly rash.”

Symptoms are many and varied depending on the tissues affected and are often not specific, for example hair loss has a variety of causes. Symptoms can be confused by co-existence with other autoimmune disease such as Sjogren’s syndrome.

Systemic lupus erythematosus should be managed by a specialist. Symptoms can be controlled with steroid therapy, but this disease can be a cause of premature death  mainly from active disease, organ failure (e.g., kidneys), infection, or cardiovascular disease from accelerated atherosclerosis.

Certain common medicines known to cause drug-induced lupus are:

  • Isoniazid
  • Hydralazine
  • Procainamide

Other less common drugs may also cause the condition. These may include:

  • Anti-seizure medications
  • Capoten
  • Chlorpromazine
  • Etanercept
  • Infliximab
  • Methyldopa
  • Minocycline
  • Penicillamine
  • Quinidine
  • Sulfasalazine

Symptoms tend to occur after taking the drug for at least 3 to 6 months.2

Although there is a strong familial aggregation, the disease is relatively uncommon and most cases are sporadic.1 According to the Center for Diseases (CDC), lupus most commonly affects women of childbearing age but also occurs in infants, children, adolescents, and men with peak occurrence between ages 15 and 40. Blacks (and possibly Hispanics, Asians, and Native Americans) are affected more than Whites.

What Is Secondary Hyperparathyroidism?

[dropcap]S[/dropcap]econdary hyperparathyroidism is a parathyroid disorder resulting from hypocalcemia (low blood calcium level) that is characterized by excessive production of parathyroid hormone in the attempt to normalize the low blood calcium by releasing calcium from bone.

Parathyroid hormone is produced by the four pea sized parathyroid glands that are located on the thyroid gland in the front of the neck. In part, because the thyroid and parathyroid glands share the same anatomic place in the body and because they have similar names, they are often confused although they have completely different actions.

Parathyroid hormone regulates calcium and the opposing mineral phosphorus in the blood. In secondary hyperparathyroidism, calcium blood levels are low to normal while phosphorus levels are increased which stimulates the outpouring of parathyroid hormone.

Q: How does secondary hyperparathyroidism differ from primary hyperparathyroidism?

A: In primary hyperparathyroidism blood calcium is high and phosphorus is low, which is the opposite of secondary hyperparathyroidism.

The most common cause of secondary hyperparathyroidism is kidney disease causing failure to reabsorb calcium followed by vitamin D deficiency and malabsorption.

What Is Type I Diabetes Mellitus?

[dropcap]T[/dropcap]ype 1 diabetes mellitus (T1DM), also termed type 1A, is an inherited autoimmune disorder in which anti-islet autoantibodies destroy the islet cells of the pancreas that secrete insulin hormone. Type 1 diabetes mellitus was formerly called juvenile diabetes because it usually afflicts persons under the age of 25 years.

Loss of insulin production results in failure to metabolize glucose. Glucose is a simple sugar that is a required source of energy for the body, especially the brain and muscles.

Type 1 diabetes mellitus is characterized by sustained fasting blood glucose levels above 126 mg/dL (hyperglycemia) with subsequent loss of glucose from the body by removal through the urine (glucosuria) as the body attempts to lower blood glucose, and cell starvation that follows.

That is, while glucose accumulates in blood, the body cannot access it. Without insulin treatment, this disorder quickly produces coma and ultimately results in death. In fact, it is 5th leading cause of death in the United States.

Q: How does insulin work?

A: Insulin moves glucose from the bloodstream into body cells where it is used or reformulated for high energy storage. For example, muscles can use glucose for immediate work or store it in the form of glygogen for later work, depending on need. Healthy insulin production keeps an 8 hour fasting blood glucose level to less than 100 mg/dL. Upon eating carbohydrate food, glucose is digested and absorbed from the small intestine into the bloodstream which then raises blood glucose levels. The elevated level is controlled by prompt action of insulin to lower it to below 140 mg/dL  within 2 hours of eating.

Insulin does not work alone. The islets of Langerhans manage glucose in the body. The islets are specialized formations located on the outer surface of the pancreas. The islets are composed of two different types of cells known as alpha and beta cells. These cells make the competing hormones that keep blood glucose within a healthy range.

Alpha cells secrete glucagon to raise blood glucose levels by triggering the body to release stored energy in the form of glycogen. In the opposite, beta cells secrete insulin to lower blood glucose by opening body cells so that glucose in blood can enter. Without insulin, glucose cannot enter cells but remains in the bloodstream where it accumulates.

Insulin is also needed to move magnesium into cells from the bloodstream. On the other side, magnesium is needed to produce insulin. Insulin has other functions such as building muscle and helping regulate cholesterol which directly impacts the sex hormones, estrogen, progesterone, and testosterone.

Onset of symptoms usually occurs over a period of days or weeks, although beta cell destruction can begin years earlier. The SEARCH for Diabetes in Youth multicenter study, funded by the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH), has determined that based on data from 2002 to 2003, a total of 15,000 youth in the United States were newly diagnosed with type 1 diabetes each year. Non-Hispanic white youth had the highest rate of new cases of type 1 diabetes according to NIH.

Type 1A diabetes mellitus has become one of the most intensively studied autoimmune disorders. It is now possible to predict its development, beginning with HLA-encoded genetic susceptibility, followed by the development of a series of anti-islet autoantibodies.1

What Is Volvulus?

[dropcap]V[/dropcap]olvulus is twisting of a loop(s) of bowel onto itself which effectively closes it thus preventing digested matter from passing and causing engorgement of the closed loop with gas and fluid.

Q: How does the bowel get untwisted?

A: This condition usually necessitates surgical correction although some do return to their proper position.

The danger is that there may develop necrosis of the twisted loop(s) in which case, if left untreated, death will ensue.
