Infectious Disease: Signs & Causes Of Mononucleosis

Infectious mono is a common cause of sore throat among adolescents, where it is called “the kissing disease”.

Symptoms are sore throat, fever, fatigue and sometimes a rash. Since the symptoms are severe and last for weeks, young kids are usually taken to the doctor.

Strep throat is the main problem mono can be confused with. There are blood Tests that can identify mononucleosis that the doctor is likely to perform, and it is important that she does so. The spleen is often enlarged and can rupture. Many other problems can develop.

Mono  is most often caused by the Epstein-Barr virus. This nasty double stranded DNA virus has recently been implicated one of the causes of multiple sclerosis, a debilitating neurologic disease.

Please refer to the attached article on mononucleosis by Mayo clinic. Wikipedia will probably give you more information than you want to know, as the links suggest.

There are many types of cells in the human body, and any of them can mutate, and become cancerous.  Cells of The immune system are no exception, ironically,  even though their one of their jobs is to fight cancer.

The plasma cell is an immune system cell that develops from lymphocytes(B-cells) and specializes in producing “Gamma Globulins”, a type of antibody.

When cancer involves plasma cells In the bone marrow it tends to crowd out the other cells. This can produce bone pain and anemia.

All of the cancer cells come from a single progenitor cell and form a “clone”. This clone produces a large amount of defective protein that would normally be combined with other proteins into the making of antibodies. The large amount of the same protein can often be  detected in the urine, as a “Bence Jones” protein.

In modern terminology, the condition is called a “monoclonal gammopathy”. This mass of protein gets into the bloodstream, and can deposit in various tissues, where it is called “amyloidosis”. The kidneys are often damaged in the process of excreting the overproduced, repetitious chains of useless protein.

I had a friend who was a pilot in the military during the Vietnam war. He was around “agent orange”,  which was on the news a lot in the 80’s. Agent orange was contaminated by a toxic chemical called Dioxin, which is known to cause cancer. My friend developed a cancer, primary amyloidosis, which is a close relative of multiple myeloma, and in his case produces what is called light chains.

His first warning was an elevated creatinine on a metabolic panel blood test, which pointed to the kidneys.  Medical investigation uncovered his plasma cell cancer, and he began treatment.  His kidneys eventually started to fail.

His daughter donated one of her kidneys, and currently he’s doing well, since medical treatment curtailed the light chain production.

Cancers: What Is Multiple Myeloma? (Mayo Clinic)

Multiple myeloma is a relatively uncommon form of blood cancer that affects less than 1% of the U.S. population, according the American Cancer Society. People younger than 45 rarely get the disease, and it occurs more in older men than women. And your risk is doubled if you’re African American.
