Insights

Systemic vasculitis, characterized by blood vessel inflammation, is better understood through advanced diagnostics and genetics. This review summarizes key classification systems, focusing on the 2012 Chapel Hill Consensus Conference (CHCC) updates.

Area of Science:

  • Rheumatology and Immunology
  • Internal Medicine
  • Pathology

Background:

  • Systemic vasculitides encompass diverse disorders marked by blood vessel inflammation.
  • Recent advancements in diagnostic tests and genetic research have significantly enhanced understanding of vasculitis pathogenesis.
  • This progress has led to revisions in vasculitis nomenclature and classification.

Purpose of the Study:

  • To review and summarize major nomenclature and classification systems for systemic vasculitides.
  • To highlight the impact of recent research on understanding vasculitis.
  • To focus on classifications derived from the 2012 Chapel Hill Consensus Conference (CHCC).

Main Methods:

  • Literature review of major vasculitis nomenclature and classification systems.
  • Emphasis on the 2012 Chapel Hill Consensus Conference (CHCC) findings.
  • Discussion of ongoing multicenter collaborative studies for improved diagnostic criteria.

Main Results:

  • Established nomenclature and classification systems for vasculitides are presented.
  • The evolution of understanding vasculitis pathogenesis is detailed.
  • The 2012 CHCC classification is highlighted as a key development.

Conclusions:

  • Understanding of vasculitis pathogenesis has substantially improved.
  • Nomenclature and classification systems have been revised based on new evidence.
  • Ongoing research aims to further refine diagnostic criteria for vasculitis.

Cardiovascular Drugs: Classification based on Therapeutic Indications

Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

Vascular Spasm01:16

Vascular Spasm

The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Angina II: Classification

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Classification of Connective Tissues01:30

Classification of Connective Tissues

The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....
