Abstract

Insights

COVID-19 severity and fatality in multiple sclerosis (MS) patients on disease-modifying treatments (DMT) were assessed. Lethality was low, with age being a significant factor for severe COVID-19 outcomes.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Epidemiology

Context:

  • Limited data exists on severe COVID-19 outcomes for multiple sclerosis (MS) patients undergoing disease-modifying treatments (DMT).
  • Assessing COVID-19 impact in this vulnerable population is crucial for clinical management.

Purpose:

  • To evaluate the severity and lethality of COVID-19 in patients with MS receiving DMT.
  • To identify factors associated with severe COVID-19 outcomes in this cohort.

Summary:

  • A prospective cohort study included 111 MS patients with confirmed COVID-19 on DMT.
  • Severe COVID-19 (ICU admission or death) occurred in 5.4% of patients; 2.7% died.
  • Age was independently associated with severe COVID-19; a trend was observed with an Expanded Disability Status Scale (EDSS) of 6.

Impact:

  • The study indicates a low lethality rate of COVID-19 among MS patients on DMT.
  • Age is a key predictor of severe COVID-19 in MS patients, highlighting the need for targeted preventive strategies.

Myasthenia Gravis: Overview and Treatment

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...

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Myasthenia Gravis: Diagnostic Tests

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...
