What is the Best Treatment for Polymyositis?

Polymyositis Treatment Guide - Latest Medications & Recovery Tips

Polymyositis is a rare condition where your immune system mistakenly targets and damages your own muscles. It's part of a group of conditions called myositis, which causes long-term muscle inflammation and weakness. 

This condition usually affects muscles in the middle part of your body, like your arms, hips, thighs, chest, back, abdomen, and neck. The exact reason behind polymyositis is not yet known. However, doctors generally focus on reducing symptoms and helping you manage the condition, so it doesn’t affect your daily life as much. 

Read on to discover the best treatment options and how to manage polymyositis more effectively. 

What Causes Polymyositis? 

Polymyositis generally occurs when the immune system mistakenly attacks healthy muscle tissue. The exact cause isn’t known completely, but here are some possible causes: 

• It may start for no clear reason (idiopathic). 
• Autoimmune diseases can increase the risk. 
• Certain viral infections may also lead to the condition. 
• Some medications or other health issues might also trigger it. 

Common autoimmune conditions linked to polymyositis include: 

• Lupus 
• Scleroderma 
• Rheumatoid arthritis 

Viral infections that might trigger polymyositis are: 

• HIV 
• COVID-19 
• Flu (Influenza) 
• Common cold 

Who is at Risk of Polymyositis? 

Polymyositis can happen to anyone, but it’s seen more often in specific groups of people. Here’s who might be at higher risk: 

1. Women are about twice as likely to develop polymyositis. 
2. People with other autoimmune conditions. 
3. It mostly affects adults aged 30 to 60, but it can occur at any age. 

What are the symptoms of polymyositis? 

Polymyositis mainly affects your muscles, but it can also cause other health issues. The symptoms may appear gradually and become more severe over time. 

Some of the common symptoms of polymyositis include: 

• Achy joints 
• Mild fever 
• Morning stiffness 
• Unexplained weight loss 
• Trouble speaking clearly 
• Muscle pain or soreness 
• Difficulty swallowing (dysphagia) 
• Constant tiredness or fatigue 
• Shortness of breath or breathing problems 
• Weak muscles, especially around your shoulders and hips 

You may also have trouble with everyday movements, like: 

• Lifting things 
• Walking up stairs 
• Reaching overhead 
• Standing up from a chair 

Note: Some symptoms can become serious. If you’re struggling to breathe or swallow, seek emergency medical care immediately. 

How is Polymyositis Diagnosed? 

Your doctor will check your body and ask about your symptoms and how strong your muscles feel to see if you might have polymyositis. They’ll also look at how you move and how your muscles react. 

Additionally, the healthcare provider may even order a few tests to confirm the condition, including: 

• Blood Tests: Assist in detecting high levels of muscle enzymes or certain antibodies that cause muscle damage. 
• MRI (Magnetic Resonance Imaging): This scan helps check for any swelling or inflammation in your muscles. 
• EMG (Electromyography): Measures how your muscles respond to nerve signals. 
• Muscle Biopsy: A small piece of muscle is taken and tested to see how healthy it is and if there's damage. 

These tests also help doctors make sure your symptoms aren’t caused by any other condition. 

What is the New Treatment for Polymyositis? 

Polymyositis can’t be completely cured, but the new treatments can help boost your muscle strength and movement. Getting treated early also offers you a better chance to prevent serious issues down the road. 

As everyone’s symptoms and recovery are different, your doctor will design a treatment plan that’s right for you. It may involve the following: 

Medications 

Here are some common medicines used to treat polymyositis: 

• Corticosteroids: Prednisone is often the first medication used. It works well to reduce inflammation and ease symptoms. But taking it for a long time can lead to serious side effects. That’s why doctors usually start with a higher dose and slowly reduce it over time. 
• Steroid-sparing Medications: These drugs are generally used along with corticosteroids to lower the dose of steroids needed and reduce their side effects. The most common ones include azathioprine. 
• Methotrexate: Other medicines that might be used include mycophenolate mofetil, tacrolimus, and cyclosporine. 
• Rituximab: This biologic therapy is used to treat autoimmune diseases by targeting specific immune cells. It is an effective option for many patients with refractory polymyositis, especially those with certain antibody profiles or whose disease is severe. 

Therapy Options 

Your doctor may also recommend one or more of the following therapies, depending on how the condition affects you: 

• Physical Therapy: A physical therapist can guide you through exercises to help you stay strong, flexible, and active without pushing your muscles too hard. 
• Speech Therapy: If polymyositis weakens the muscles you use for swallowing, speech therapy can teach you the best ways to manage and improve those functions. 
• Dietary Support: As the condition gets worse, it may become difficult to chew and swallow. A dietitian can help you plan meals that are easier to eat and still provide the nutrition you need. 

Other Treatments 

• Intravenous Immunoglobulin (IVIg): This treatment mainly uses purified antibodies from healthy donors. It’s given through a vein and works by blocking the harmful antibodies attacking your muscles. The effects may not last permanently, so treatments usually need to be repeated over time. 

Polymyositis can be managed with the right care. Early diagnosis and a personalised treatment plan can improve quality of life. However, treating polymyositis can be costly, as it usually requires long-term care, regular doctor visits, lab tests, medications, and therapies. Having health insurance during this tough time helps manage these expenses by covering a major part of the treatment cost.
