Insights

Recent advances in large vessel vasculitis research highlight new imaging techniques for monitoring disease activity and potential genetic links to giant cell arteritis (GCA) and Takayasu arteritis (TA). Antitumor necrosis factor-alpha therapies show promise for refractory cases.

Area of Science:

  • Rheumatology
  • Immunology
  • Radiology

Background:

  • Giant cell arteritis (GCA) and Takayasu arteritis (TA) are large vessel vasculitides with unknown causes.
  • Both conditions share similar clinical manifestations, necessitating a review of recent findings.

Purpose of the Study:

  • To review recent clinical and pathophysiological advances in GCA and TA.
  • To focus on research published within the past year.

Main Methods:

  • Review of recent scientific literature on GCA and TA.
  • Analysis of imaging techniques, including delayed gadolinium-enhanced MRI.
  • Examination of genetic association studies and therapeutic advancements.

Main Results:

  • Delayed gadolinium-enhanced MRI shows potential for monitoring aortic wall inflammation in TA and small vessel inflammation in GCA.
  • Antitumor necrosis factor-alpha monoclonal antibody therapy demonstrates efficacy in patients resistant to standard treatments.
  • Gene polymorphisms in inducible nitric oxide synthase and I-kappaB-like protein are associated with susceptibility to GCA and TA, respectively.

Conclusions:

  • Advanced imaging techniques offer improved evaluation of vascular lesion activity and treatment guidance for GCA and TA.
  • Further elucidation of pathophysiological mechanisms may lead to novel targeted therapies, such as anti-TNF-alpha agents.

Rheumatic Heart Disease I: Introduction01:23

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...
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...

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...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
Myocarditis I: Introduction01:21

Myocarditis I: Introduction

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...
T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...
