Summary
Giant cell arteritis (GCA) with large vessel vasculitis (LVV) rarely affects vessels beyond the aorta. This study highlights four cases of LVV-GCA without aortitis, emphasizing the need for further research.
Area of Science:
- Rheumatology
- Vascular Medicine
- Immunology
Background:
- Giant cell arteritis (GCA) is the most common vasculitis in individuals over 50.
- Large vessel vasculitis (LVV) occurs in 40-70% of GCA cases, typically involving the aorta.
- Extracranial LVV in GCA is infrequently documented.
Purpose of the Study:
- To describe cases of LVV-GCA presenting without aortitis.
- To characterize the clinical presentation and diagnostic findings in this rare GCA phenotype.
- To discuss the implications for patient management and prognosis.
Main Methods:
- Case series of four patients with LVV-GCA.
- Diagnostic tools included PET-CT, CT angiography, temporal artery biopsy, and ophthalmological examination.
- Clinical data on disease progression and treatment response were collected.
Main Results:
- Four cases of LVV-GCA without aortitis were identified.
- Vessel involvement included limb arteries (3 cases) and mesenteric artery (1 case).
- Three patients demonstrated corticosteroid dependence; one patient was lost to follow-up.
Conclusions:
- LVV-GCA without aortitis is a rare but distinct clinical entity.
- Corticosteroid dependence was observed in a majority of the reported cases.
- Further large-scale studies are required to establish the prognosis and optimal therapeutic strategies for this GCA variant.

Structure of Blood Vessels
9.7K
Blood is circulated throughout the human body through a network of blood vessels called the circulatory system. This system includes arteries that transport blood from the heart to various body parts. These arterial pathways divide into smaller vessels until they reach the arterioles, which further split into capillaries. It is within these minuscule capillaries that the exchange of nutrients and waste products takes place. After this exchange, the blood is collected by venules, which fuse to...

Anatomy of Blood Vessels

The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta,...

Development of Blood Vessels
1.5K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Overview of Blood Vessels

The human cardiovascular system comprises five primary types of blood vessels: arteries, arterioles, veins, venules, and capillaries, each serving unique functions.
Arteries and Arterioles: Arteries are muscular and elastic vessels that primarily carry oxygenated blood from the heart to body tissues, except for the pulmonary artery, which carries deoxygenated blood. They have thick walls to withstand high pressure and contain a layer of muscle tissue, allowing them to expand or contract as...

Dipeptidyl Peptidase 4 Inhibitors
685
Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...

Amides to Amines: LiAlH4 Reduction
6.3K
Amide reduction with strong reducing agents like lithium aluminum hydride proceeds through a nucleophilic acyl substitution to form amines. Primary, secondary, and tertiary amides yield primary, secondary, and tertiary amines, respectively.
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.
