Summary
Idiopathic inflammatory myopathies (IIM) require immune-modulating treatments, starting with corticosteroids. Advanced therapies like immunosuppressants, IV immunoglobulin, and biologics are used for refractory cases, with gradual drug tapering for long-term management.
Area of Science:
- Rheumatology and Immunology
- Neuromuscular Diseases
Context:
- Idiopathic inflammatory myopathies (IIM) are a group of rare autoimmune disorders affecting muscles.
- Effective management of IIM is crucial to prevent progressive muscle weakness and disability.
Purpose:
- To outline the current therapeutic strategies for managing idiopathic inflammatory myopathies.
- To describe the stepwise approach to immune-modulating treatments for IIM.
Summary:
- First-line treatment for IIM involves corticosteroids (e.g., prednisolone).
- For refractory cases, immunosuppressive agents (e.g., azathioprine, methotrexate) are introduced.
- Intravenous immunoglobulin and biologics (e.g., rituximab) are considered for severe or non-responsive disease, followed by gradual drug tapering.
Impact:
- Provides a clear treatment algorithm for clinicians managing IIM patients.
- Highlights the importance of a tailored, multi-modal therapeutic approach.
- Aims to improve patient outcomes and quality of life by controlling inflammation and preserving muscle function.

160
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

01:20Myasthenia Gravis: Overview and Treatment
1.7K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
207
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
181
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

01:28Classification of Skeletal Muscle Relaxants
2.5K
Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
Peripherally acting skeletal muscle relaxants interfere with the neurotransmission at the neuromuscular end plate to induce paralysis during...
