Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

391
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Myasthenia Gravis: Overview and Treatment

1.2K
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...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

382
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

435
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers01:26

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

140
Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Acute Pancreatitis II: Clinical Manifestations and Management

93
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Summary

Giant cell arteritis (GCA) relapses are common, even with treatment. Frequent relapses increase risks of vascular damage and steroid side effects, highlighting the need for better management strategies.

Area of Science:

  • Rheumatology
  • Immunology
  • Vascular Medicine

Background:

  • Giant cell arteritis (GCA) is a relapsing large vessel vasculitis.
  • High relapse rates occur with glucocorticoid monotherapy (50%) and tocilizumab (30%).
  • Relapses can lead to significant vascular damage and treatment-related morbidity.

Purpose of the Study:

  • To provide expert insights into the practical diagnosis and management of GCA relapses.
  • To review current treatment options for GCA relapses.
  • To discuss novel potential therapies for GCA.

Main Methods:

  • Expert perspective on GCA relapse diagnosis and management.
  • Review of current treatment options based on international guidelines.
  • Exploration of emerging therapies for GCA.

Main Results:

  • GCA relapses are frequent, impacting long-term patient outcomes.
  • Interleukin-6 blockade (tocilizumab) reduces relapse frequency but does not induce tolerance.
  • Persistent disease activity is linked to increased vascular morbidity.

Conclusions:

  • Effective management of GCA relapses is crucial to minimize vascular damage and treatment toxicity.
  • Current therapies, while suppressing disease activity, do not offer a definitive cure.
  • Further research into novel therapies is warranted to improve long-term GCA management.
