Diagnostic Approaches for Large Vessel Vasculitides.

Open Access Rheumatol 2021 1;13:153-165. Epub 2021 Jun 1.

Department of General Internal Medicine, University Hospitals Leuven, Leuven, Belgium.

The large vessel vasculitides comprise giant cell arteritis (GCA), Takayasu arteritis (TAK), and chronic periaortitis. The diagnostic approach to these conditions involves the correct use and interpretation of clinical criteria, imaging techniques, and, in case of GCA, temporal artery biopsy. Ultrasound, magnetic resonance imaging (MRI), and computed tomography (CT) reveal a homogeneous, concentric, thickening of the arterial wall. Read More

Long-term monitoring of chronic demyelination and remyelination in a rat ischemic stroke model using macromolecular proton fraction mapping.

J Cereb Blood Flow Metab 2021 Jun 9:271678X211020860. Epub 2021 Jun 9.

Laboratory of Neurobiology, Tomsk State University, Tomsk, Russian Federation.

Remyelination is a key process enabling post-stroke brain tissue recovery and plasticity. This study aimed to explore the feasibility of demyelination and remyelination monitoring in experimental stroke from the acute to chronic stage using an emerging myelin imaging biomarker, macromolecular proton fraction (MPF). After stroke induction by transient middle cerebral artery occlusion, rats underwent repeated MRI examinations during 85 days after surgery with histological endpoints for the animal subgroups on the 7th, 21st, 56th, and 85th days.

A Distinct Macrophage Subset Mediating Tissue Destruction and Neovascularization in Giant Cell Arteritis: Implication of the YKL-40 - IL-13 Receptor α2 Axis.

Arthritis Rheumatol 2021 Jun 8. Epub 2021 Jun 8.

Department of Rheumatology and Clinical Immunology, University of Groningen, University Medical Center Groningen, Groningen, The Netherlands.

Objective: Macrophages mediate inflammation, angiogenesis and tissue destruction in giant cell arteritis (GCA). Serum levels of the macrophage-associated protein YKL-40 (chitinase-3 like-1), previously linked to angiogenesis and tissue remodeling, remain elevated in GCA despite glucocorticoid treatment. Here, we aimed to investigate the contribution of YKL-40 to vasculopathy in GCA. Read More

Resection of a Large Cavernous Hemangioma Following Preoperative Embolization in a Child's Temporal Bone.

J Int Adv Otol 2021 May;17(3):269-274

Department of Otorhinolaryngology-Head and Neck Surgery, Keio University School of Medicine, Shinjuku-ku, Tokyo, Japan.

Primary intraosseous cavernous hemangiomas (PICHs) in the temporal bone are very rare. Most treated cases are in adult patients, and there are very few reports involving children. To our knowledge, no cases reported have ever actually adopted embolization in children, although several reports recommend preoperative embolization of the feeding arteries. Read More

Bilateral Vertebral Artery Vasculitis-A Rare Manifestation of Giant Cell Arteritis and a Difficult Diagnosis Made Possible by 2-[F]FDG PET/CT.

Diagnostics (Basel) 2021 May 14;11(5). Epub 2021 May 14.

Department of Ophthalmology, Rigshospitalet, University of Copenhagen, 2600 Glostrup, Denmark.

Giant cell arteritis (GCA) is the most common form of large vessel vasculitis. GCA is a medical and ophthalmological emergency, and rapid diagnosis and treatment with high-dose corticosteroids is critical in order to reduce the risk of stroke and sudden irreversible loss of vision. GCA can be difficult to diagnose due to insidious and unspecific symptoms-especially if typical superficial extracranial arteries are not affected. Read More

[Giant Cell Arteritis].

Brain Nerve 2021 May;73(5):496-502

Department of Neurology, Nippon Medical School.

Giant cell arteritis (GCA), also referred to as temporal arteritis, is a variant of large-vessel vasculitis. GCA should be considered in the differential diagnosis in patients aged >50 years, who present with headache, abrupt onset of visual disturbances, unexplained fever, a high erythrocyte sedimentation rate, and high serum C-reactive protein levels. Diagnosis of GCA is based on accurate interpretation of laboratory data, temporal artery biopsy findings, and imaging study results. Read More

Br J Nurs 2021 May;30(9):512-519

Advanced Nurse Practitioner, Manchester Royal Eye Hospital, Manchester University NHS Foundation Trust.

Giant cell arteritis (GCA) is an uncommon autoimmune inflammatory vasculopathy that can lead to the destruction and occlusion of various arteries that consequently can cause serious complications such as stroke or sight loss. It is seen as a medical emergency. The most commonly affected vessel in GCA is the temporal artery in the side of the head, hence the condition is sometimes also referred to as 'temporal arteritis'.

Department of Ultrasound, The Second Affiliated Hospital of Dalian Medical University, Dalian 116031, China.

To explore the application value of color duplex sonography and enhanced computerized tomography (CT) inspection based on a nanocontrast agent in diagnosis and pathogenesis in giant cell arteritis (GCA), the GCA nude mouse model was constructed. In this study, 40 healthy male BalB/c nude mice aged 6-8 weeks were randomly divided into a control group (no model) and an experimental group (model), with 20 mice in each group, and the temporal artery tissue of GCA patients diagnosed as positive by temporal artery biopsy was implanted into nude mice to construct a GCA nude mouse model. Abdominal aortic biopsy and immunohistochemistry were used to verify the success of the GCA nude mouse model. Read More

Assessing cerebral arterial pulse wave velocity using 4D flow MRI.

J Cereb Blood Flow Metab 2021 Apr 14:271678X211008744. Epub 2021 Apr 14.

Department of Radiation Sciences, Umeå University, Umeå, Sweden.

Intracranial arterial stiffening is a potential early marker of emerging cerebrovascular dysfunction and could be mechanistically involved in disease processes detrimental to brain function via several pathways. A prominent consequence of arterial wall stiffening is the increased velocity at which the systolic pressure pulse wave propagates through the vasculature. Previous non-invasive measurements of the pulse wave propagation have been performed on the aorta or extracranial arteries with results linking increased pulse wave velocity to brain pathology.
