Insights

Giant cell arteritis (GCA) is an immune-mediated vasculitis in older adults, causing inflammation in large arteries. Early recognition of neurological or visual symptoms and prompt corticosteroid treatment are crucial for halting disease progression.

Area of Science:

  • Rheumatology
  • Immunology
  • Vascular Medicine

Background:

  • Giant cell arteritis (GCA) is an immune-mediated vasculitis affecting medium and large arteries in individuals over 50.
  • Clinical manifestations range from tissue ischemia due to vascular lesions to systemic inflammatory responses.
  • Distinct pathogenesis is proposed: adaptive immunity for vascular lesions and innate immunity for systemic inflammation.

Purpose of the Study:

  • To summarize the key aspects of Giant Cell Arteritis.
  • To highlight the clinical presentation and underlying immune mechanisms.
  • To emphasize the importance of early diagnosis and treatment.

Main Methods:

  • Review of existing literature on Giant Cell Arteritis.
  • Analysis of clinical manifestations and proposed pathogenetic pathways.
  • Emphasis on diagnostic suspicion and therapeutic interventions.

Main Results:

  • GCA presents with diverse symptoms, including those from ischemia and systemic inflammation.
  • Vascular lesions are linked to adaptive immunity, while systemic inflammation involves innate immunity.
  • High index of suspicion is needed for neurological/visual symptoms.

Conclusions:

  • Prompt high-dose corticosteroid treatment is invaluable in halting GCA progression.
  • Understanding the distinct immune responses is key to managing GCA.
  • Early diagnosis and intervention are critical for preventing irreversible damage.

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
Hypersensitivity Reactions: Immune-Complex Reactions01:19

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
