Myasthenia Gravis: Overview and Treatment

3.4K
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...

Myasthenia Gravis: Diagnostic Tests

3.1K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Myocarditis I: Introduction

563
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Necrosis01:16

Necrosis

7.2K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Disorders of the Skeletal Muscle

2.3K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Myocarditis II: Clinical Features and Diagnostic Tests

441
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Area of Science:

  • Neurology
  • Immunology
  • Rheumatology

Background:

  • Immune-mediated necrotizing myopathy (IMNM) is a rare, severe idiopathic inflammatory myopathy characterized by symmetrical proximal muscle weakness.
  • Autoimmune aspects are indicated by autoantibodies against signal recognition particle (SRP) and HMGCR, with statin use linked to anti-HMGCR IMNM.
  • Pathophysiological mechanisms remain poorly understood, and validated therapeutic strategies are lacking.

Purpose of the Study:

  • To provide a comprehensive overview of immune-mediated necrotizing myopathy (IMNM).
  • To summarize current knowledge on IMNM epidemiology, clinical features, and pathophysiology.
  • To review existing and potential treatment strategies for IMNM.

Main Methods:

  • Literature review of recent studies on IMNM.
  • Analysis of epidemiological data.
  • Synthesis of clinical and pathological findings.
  • Evaluation of current therapeutic approaches.

Main Results:

  • Significant progress has been achieved in the diagnosis and management of IMNM.
  • The association of IMNM with specific autoantibodies (anti-SRP, anti-HMGCR) aids in classification.
  • Statin-associated anti-HMGCR IMNM is a recognized clinical entity.

Conclusions:

  • Immune-mediated necrotizing myopathy (IMNM) is an area of active research with ongoing advancements.
  • Diagnosis and patient management have improved considerably.
  • Further investigation into pathophysiological mechanisms and effective treatment strategies is crucial.
