Sepsis and Multiple Sclerosis

Multiple sclerosis is a disease that affects your brain and nervous system. Currently, about 1 million people in the United States have MS. As with many progressive and chronic diseases, like diabetes or COPD, people with MS are at higher risk of contracting infections, which also puts them at higher risk of developing sepsis.

Sepsis is a life-threatening emergency that happens when your body’s response to an infection damages vital organs and, often, causes death. Like strokes or heart attacks, sepsis is a medical emergency that requires rapid diagnosis and treatment.

Multiple sclerosis is a disease where nerve fibers, called myelin, are destroyed. No one knows yet what causes MS, but it is considered to be an autoimmune disorder as your immune system attacks the myelin. Your body needs these fibers to transmit messages within the central nervous system (CNS). These messages allow your brain to tell your body to do things, like use your finger to push an elevator button or your leg to take a step.

As the damage to the fibers progress, scar tissue remains, blocking further transmissions.

The most common types of MS are:

  • Relapse-remitting MS (RMSS): Up to 85% of people with MS have RMSS when they are first diagnosed. It causes relapses or attacks after periods of few or no symptoms. Quiet periods can last months, even years and people can stay in this stage. Eventually, about 50% of people with RMSS progress to SPMS.
  • Secondary-progressive (SPMS): Rather than having periods of stability alternative with relapses, people with SPMS see a slow, steady progression of symptoms.
  • Primary-progressive (PPMS): About 10% of people diagnosed with MS have PPMS, which starts with symptom progression right from the time you are diagnosed.

Infection Risk

It used to be believed that people with MS got more infections because the medications for MS lower a person’s immune response to viruses, bacteria, and fungi. While this is still true, a study published in 2020 found that people diagnosed with MS had more infections than their peers without MS around the time they were diagnosed, before they started taking medications. The most common ones were urinary tract and kidney infections, as well as influenza, pneumonia, and other respiratory infections.

With the increase of infections comes an increase in hospitalizations, almost three times as often compared with peers who do not have MS.

At-Risk Groups

Anyone can get MS, but it is most frequently diagnosed among people who:

  • Were born female
  • Are 20 to 40 years old
  • Have a family history of MS
  • Are white, particularly of Northern European descent
  • Live in cooler climates
  • Have other autoimmune disorders, like type 1 diabetes
  • Smoke
Symptoms

Multiple sclerosis symptoms are quite subtle at first, to the point that it is easy to brush them off as a one-off thing, or due to stress. They include:

  • Numb or weak feeling in one or more limbs, most often on one side only
  • A feeling like an electric shock that comes with bending your neck or other movements
  • Difficulty walking
  • Tremor in your hand(s)
  • Vision changes: blurry vision, seeing double, or even partial or complete loss of sight
  • Fatigue
  • Dizziness
  • Difficulty speaking
Treatment

Currently, there is no cure for MS and medications work to slow down how quickly it progresses. The medications, such as steroids, increase your risk of contracting an infection. This is why people with MS should be watchful for any signs or symptoms of an infection of any kind.
