Enspryng and NMOSD: Learn about this rare condition (Neuromyelitis Optica Spectrum Disorder)

Have you suddenly noticed a change in your vision, eye pain, or numbness or weakness in your limbs? It could be something else. Today we are talking about a condition that is not very common in our country, but it is very important to be aware of. That is Neuromyelitis Optica Spectrum Disorder , or NMOSD for short. This is an autoimmune disease that mainly affects your eyes and spinal cord.

What is NMOSD? How does Enspryng work?

Simply put, NMOSD is when your body's own immune system, the system that protects us from disease, mistakenly starts attacking your own healthy cells. Specifically, your body starts making antibodies against a specific protein in your nervous system called `aquaporin-4 (AQP4).'

This attack mainly causes inflammation, or inflammation, around your optic nerve (the nerve that carries messages between your eye and your brain) and spinal cord. As this continues, it can lead to vision loss and difficulty walking.

There is no cure for NMOSD yet. Treatments are mainly aimed at reducing inflammation, controlling symptoms , and preventing relapses.

This is where Enspryng comes in. Enspryng is a new biologic medicine. This medicine can help prevent NMOSD from coming back, especially if you have the anti-AQP4 antibodies we talked about earlier in your blood.

Enspryng works by blocking another protein in our body called ``interleukin-6 (IL-6).`` Because this protein called IL-6 is also involved in the inflammation caused by the anti-APQ4 antibodies. So when IL-6 is blocked, inflammation is reduced, symptoms are controlled, and the disease can be reduced.

How should I use this medicine?

Enspryng is a subcutaneous injection . It is usually given in the lower abdomen or the front middle of the thigh.

• The first three injections should be given every two weeks.
• After that, you only have to hit it once a month.

It is very important to remember the exact days when you need to get these injections. Set a reminder on a calendar or on your phone. If you miss an injection, you should definitely talk to your doctor about what to do next.

Don't worry, your doctor will train you on how to give yourself this injection, where to give it, and how to change the site each time. Always wash your hands thoroughly before giving the injection.

How should I store the medicine?

This medicine should be kept in the fridge . But do not keep it in the freezer. Also, do not shake the medicine. Take the medicine out 30 minutes before the injection and let it come to room temperature. Never heat the medicine in the microwave or with hot water.

How has this medicine been researched?

Two major studies have been conducted to look at the safety and effectiveness of Enspryng. These compare Enspryng to a placebo, a drug that has no active ingredient. This is when we can really tell if the drug is actually beneficial or harmful.

All participants in this study had NMOSD, a history of relapses, and a score between 0 and 6.5 on the Expanded Disability Status Scale (EDSS), a scale that measures their level of disability. (EDSS scores of 0 mean no disability, 6.5 mean some limitation in walking.)

The research primarily looked at how long it took for the disease to recur. In addition, attention was paid to changes in the `Visual Analog Scale (VAS)`, which measures pain, and the `Functional Assessment of Chronic Illness Therapy (FACIT)`, which measures fatigue.

What are the results of the research?

In both studies, patients taking Enspryng had significantly fewer relapses than those taking placebo. This means that Enspryng can reduce your symptoms and the number of relapses.

However, patients without anti-AQP4 antibodies did not benefit significantly from Enspryng compared to placebo.

How to manage side effects if they occur?

The most common side effects of this medicine are nose and throat infections, headache, nausea, skin rash, gastritis, fatigue, and pain in the limbs or joints. Tell your doctor if you have any of these.

Infections

There is a slightly increased risk of developing common or serious infections while taking Enspryng. Tell your doctor if you are being treated for an infection. Also, tell your doctor right away if you have any of the following symptoms:

• Cold, body aches, fever, sore throat, persistent cough
• Skin redness or swelling
• Stomach upset, diarrhea
• Burning when urinating or a frequent need to urinate

Rash

Tell your doctor if you develop a skin rash while taking the medicine. If the rash suddenly spreads all over your body, go to a hospital's emergency room (ETU) immediately.

These are not the only possible side effects. If you have any symptoms that are bothering you, talk to your doctor about them.

What tests should be done before starting treatment and during treatment?

Before you start Enspryng, your doctor will do several blood tests to check your liver function, hepatitis B, tuberculosis, or other infections. These tests may need to be repeated during treatment. So it's very important to have your tests done on time.

Can there be problems with other medications?

There have been no reported major interactions between Enspryng and food or other medications. However, it is important to tell your doctor about all medications you are taking (including medications for other conditions, vitamins, herbal remedies, and supplements). This can help prevent any unwanted side effects.
