Insights

Giant cell arteritis (GCA) treatment requires individualized care, especially for neuro-ophthalmic and neurological complications. High-dose steroids and close monitoring are recommended for acute cases, while long-term steroid-sparing options need further study.

Area of Science:

  • Rheumatology
  • Neurology
  • Ophthalmology

Background:

  • Giant cell arteritis (GCA) is a vasculitis responsive to corticosteroids, but long-term management challenges persist.
  • GCA presents diverse clinical subtypes, necessitating tailored treatment strategies.
  • Existing literature shows varied recommendations for GCA management.

Purpose of the Study:

  • To systematically review treatment options for neuro-ophthalmic and neurological complications of GCA.
  • To evaluate evidence for adjuvant therapies in GCA management.
  • To provide recommendations for managing acute GCA complications.

Main Methods:

  • Systematic literature review of treatment options for GCA with ocular and neurological involvement.
  • Analysis of evidence for adjuvant therapies.
  • Formulation of clinical recommendations based on available data.

Main Results:

  • No randomized controlled trials specifically address GCA with ocular/neurological complications.
  • Hospital admission for high-dose intravenous methylprednisolone is recommended for acute visual loss or brain ischemia.
  • Aspirin may offer benefits; evidence for steroid-sparing agents like methotrexate is debated.

Conclusions:

  • Individualized treatment is crucial for GCA, particularly for severe complications.
  • Prompt, high-dose corticosteroid therapy and monitoring are vital for acute neuro-ophthalmic/neurological GCA.
  • Further research is needed to clarify the role of steroid-sparing agents in long-term GCA management.

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

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.

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

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...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

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 (Humira),...
