Do you sometimes feel like you have a hard time holding things, buttoning a button, or even walking? You might be thinking, "Oh, this is just something that happens when you get older." But sometimes, these things aren't so simple. Today, we're going to talk about a rare but very important condition to be aware of. That's called `Inclusion Body Myositis`, also known as `(IBM)` for short.
What is `Inclusion Body Myositis (IBM)`? Let's understand it simply!
Simply put, `Inclusion Body Myositis` is a condition that gradually weakens your muscles, but it doesn't cause much pain. It usually starts after the age of 50. Think about it, you may have difficulty `pinch` something small, have difficulty `grasp` something, or even trip and fall when you just walk. These are the early signs that you may notice.
This condition, called `IBM`, develops gradually over many years. It is not a life-threatening condition. This means that it will not kill you. However, over time, it can make it difficult to carry out daily activities, which can lead to some degree of disability. Sometimes, only one side of your body is affected more. About half of people with this condition may also have `swallowing difficulties`.
Unfortunately, there is no cure for IBM yet. But don't worry! Physical therapy can help you maintain your muscle strength for as long as possible.
How common is this `IBM` situation?
Inclusion Body Myositis is a condition that belongs to a group of muscle-weakening diseases called myopathies. Myopathies are diseases that attack and weaken your muscle fibers. Research suggests that IBM affects between 5 and 9 out of every million adults. It is also about three times more common in men than in women (3:1).
What are the symptoms of `Inclusion Body Myositis (IBM)`? Let's find out exactly!
The muscle weakness caused by IBM comes on very slowly. It often starts in the limbs. You may first notice weakness in your legs, thighs, or hands, wrists, or fingers. Think about it this way: some people have difficulty buttoning a shirt, or their pens don't write smoothly. Others have difficulty climbing stairs, or they stumble and fall while just walking.
As symptoms gradually worsen, you may notice things like:
- Muscles in the arms, legs, shoulders, hip area, palms, and fingers gradually become weaker. Imagine, you can't lift things that you used to be able to lift easily, and you have trouble getting up from a chair.
- Weakening of the muscles in the neck or esophagus. This can make it difficult to hold the head upright, make it difficult to swallow food, and can even cause food to get stuck.
- Muscle atrophy is clearly visible. This means that the muscles have shrunk and become very thin.
- Mild, frequent muscle pain (`myalgia`). However, this pain does not occur in everyone, and even if it does occur, it is not very severe.
For example, imagine that you have a friend named Sunil. He has been unable to hold his teacup properly for some time now, it keeps slipping from his hand. When he goes to read the newspaper, his hand feels like it is shaking. At first, he thought it was just fatigue. But later, he realized that this could be an early symptom of `IBM`.
Why does this `Inclusion Body Myositis (IBM)` occur? What is the cause?
In fact, this condition called `Inclusion Body Myositis` is `idiopathic`. That is, it seems to occur without any specific cause. Like other types of `myositis`, in this case, long-term inflammation in the muscles (`chronic inflammation`) is the main cause of muscle weakness. However, researchers still do not know exactly why this inflammation occurs. They suspect that it may be due to a problem with the immune system (`autoimmune disease`) . That is, the cells that protect our body mistakenly attack our own muscle cells.
`Inclusion bodies` are also related to `IBM`. These are abnormal protein clumps that are deposited inside muscle cells. They can be caused by a viral infection, cellular damage, or genetic mutations . These `inclusion bodies` are also seen in neurodegenerative diseases like `ALS`. They can interfere with the normal functioning of cells.
Difference between `Inclusion Body Myopathy` and `Inclusion Body Myositis`
Sometimes `Inclusion Body Myositis` is also called `sporadic inclusion body myositis (sIBM)`. `Sporadic` means that it occurs randomly, or without a specific cause. This is to distinguish it from similar conditions that are hereditary. Those that are hereditary are called `hereditary inclusion body myopathies (hIMB)`. When we say `inclusion body myopathies`, both of these types belong. We are now talking about the `sIBM` that occurs randomly.
How is `Inclusion Body Myositis` diagnosed? What tests are done?
To find out if you have IBM, a doctor will first ask you about your symptoms and examine your muscles. The symptoms of inclusion body myositis can be similar to those of other conditions, such as polymyositis and myasthenia gravis. Your doctor will look for specific things like:
- What muscles are affected? (e.g., in the fingers or thighs?)
- Is only one side of the body affected more?
- Is muscle atrophy clearly visible?
- How old were you when symptoms started? (Usually after age 50)
Then, several tests may be done to ``rule out`` other conditions, such as:
- Creatine Kinase (CK) test: This measures the level of a special enzyme in the blood. This `CK` level can increase when there is damage to the muscles.
- Blood tests for viruses and various autoimmune diseases.
- Electromyogram (EMG): This measures the electrical activity in your muscles. It is done by inserting small needles into the muscles.
- Nerve Conduction Study (NCS): This measures the speed at which an electrical impulse travels through the nerves (motor nerves) that control your muscles.
Muscle biopsy test
The best way to confirm whether you have inclusion-body myositis is to take a small piece of tissue (a biopsy) from the affected muscle. A pathologist will look at this tissue sample under a microscope. If you have IBM, he or she will be able to see inclusion bodies (abnormal protein clumps, bubbles, or vacuoles) in the sample.
Is there any effective treatment for `Inclusion Body Myositis`?
Unfortunately, there is no effective treatment for inclusion body myositis. Unlike other inflammatory conditions and autoimmune diseases, it does not respond to corticosteroids or immunosuppressant drugs.
But don't give up hope! Physical therapy and regular exercise are essential to maintain your muscle strength for as long as possible. Exercise can help prevent further muscle weakness.
As the disease progresses and it becomes difficult to carry out daily activities, you may need to learn new ways to do things. This is where occupational therapy can help. For example, they may teach you how to use various devices to help you get dressed, eat, and write. Some people may also need to learn how to use a wheelchair. If you have swallowing difficulties, a Speech-Language Pathologist (SLP) can help. They can teach you how to swallow safely and do swallowing exercises.
If I have `Inclusion Body Myositis`, what should I expect?
If you have IBM, it will progress slowly. As mentioned earlier, this will not affect your lifespan. However, it may have an impact on your quality of life. You may need to rely on others or learn new ways of doing things. Most people will not lose their ability to walk completely, but some may need a wheelchair after 10-15 years.
How do I take care of myself while living with inclusion-body myositis?
You will have to live with `Inclusion body myositis` for a long time, and it can become a bit challenging over time. The best way to cope with this is to make a long-term plan to take care of your physical and mental health. That means continuing to practice small habits that help you stay well. For example:
- Continue your exercise program. You may be in physical therapy, or you may have switched to a home exercise program. Continuing this routine will help keep your muscles as strong as possible.
- Follow a ``wellness lifestyle.'' If you eat well, sleep well, manage stress, and maintain your important relationships, you will feel better overall.
- Join support groups. You can get a lot of mental strength and practical advice from other people who have gone through or are going through the same thing you are. It's also great to feel like "I'm not the only one going through this."
- Look into adaptations at home and at work. There are many mobility aids and assistive devices that can help people with physical disabilities to make everyday tasks easier.
- See your doctor regularly. Stay in touch with your doctor. Tell your doctor right away if you notice any new symptoms, such as difficulty swallowing, or if an existing symptom gets worse.
- Look into clinical trials. Researchers are constantly looking for new treatments that may help with inclusion body myositis. You can also take part in these trials.
This condition, called `Inclusion body myositis`, often occurs in midlife, when there is no hope. No one expects to suddenly develop an incurable, progressive disease. It can be a bit difficult to cope with and explain to those who care about you, especially if they have never heard of this disease before.
But remember, this is a very slow-growing disease. So, there is plenty of time to think about the changes ahead and make adjustments accordingly. No one can say for sure how this will affect you. However, with an optimistic approach, there are many things you can do to maintain your overall health and well-being in the years ahead.
