Giant cell arteritis (GCA) is an inflammatory vasculitis affecting large and medium-sized arteries, leading to complications such as arterial dissection, blindness, and stroke. Rarely, GCA presents with Horner's syndrome due to sympathetic neuron involvement from arterial inflammation. This case report discusses an 82-year-old female with hypertension, atrial fibrillation, and arthritis who presented with a 24 h history of right eye ptosis, blurred vision, dizziness, and aching eye pain.

Department of Ophthalmology and Vision Sciences, University of Toronto, Toronto, Ontario, Canada

Giant cell arteritis (GCA) is a vasculitis characterised by arterial inflammation, with permanent vision loss being a feared complication. The association between GCA and viral infections is well-known, but there is limited data regarding its relationship to COVID-19. A man in his 80s with a recent history of COVID-19 developed sudden vision loss, persistent headaches and jaw claudication.

Purpose: To determine if paracentral acute middle maculopathy (PAMM) and peripapillary intraretinal and subretinal fluid (IRF/SRF) could help distinguish between arteritic anterior ischemic optic neuropathy (A-AION) and non-arteritic AION (NA-AION) at an early stage.

Design: Nested prospective cross-sectional diagnostic accuracy study.

Methods: This study used single-center optical coherence tomography (OCT) data from 8 patients with A-AION and 24 patients with NA-AION from two prospective cross-sectional studies with consecutive sampling (ClinicalTrials.

Article Synopsis
  • Large vessel vasculitides (LVV) are inflammatory disorders that primarily affect large arteries like the aorta, often linked to conditions such as giant cell arteritis and Takayasu arteritis, with age and gender influencing prevalence.
  • Giant cell arteritis commonly occurs in individuals over 50, especially women, while Takayasu arteritis typically affects younger women; both require urgent diagnosis to prevent serious complications like blindness or artery damage.
  • Noninvasive imaging techniques, such as ultrasound and MRI, have revolutionized the diagnosis and management of LVV, reducing the need for invasive procedures and aiding in monitoring treatment response and disease progression.

Disease-modifying therapies for Alzheimer's disease (AD) are likely to be most beneficial when initiated in the presymptomatic phase. To track the benefit of such interventions, fluid biomarkers are of great importance, with neurofilament light chain protein (NfL) showing promise for monitoring neurodegeneration and predicting cognitive outcomes. Here, we update and complement previous findings from the Dominantly Inherited Alzheimer Network Observational Study by using matched cross-sectional and longitudinal cerebrospinal fluid (CSF) and plasma samples from 567 individuals, allowing timely comparative analyses of CSF and blood trajectories across the entire disease spectrum.

Article Synopsis
  • Giant cell arteritis (GCA) is a serious condition that can be difficult to diagnose, making early detection crucial to prevent complications; recent guidelines recommend temporal artery biopsy or ultrasound for confirmation.
  • This study evaluated the effectiveness of a fast-track ultrasound clinic run by trained rheumatologists in diagnosing GCA by analyzing data from 99 patient visits between 2020 and 2022.
  • Results showed that temporal artery ultrasound had a high sensitivity (86.3%) and specificity (90.9%), indicating it could be a reliable alternative to biopsy for diagnosing GCA in the fast-track setting.

Article Synopsis
  • Giant cell arteritis (GCA) primarily affects women over 50, causing symptoms like headaches and jaw pain, and can lead to severe complications like vision loss due to eye involvement.
  • Diagnosis relies on advanced imaging techniques such as FDG-PET and CT scans, while the temporal artery biopsy is considered the gold standard.
  • Urgent treatment with high doses of corticosteroids is critical to prevent vision loss, and long-term management is necessary to monitor for recurrence and potential cardiovascular issues.

Background: The purpose of this meta-analysis was to compare the surgical outcomes of head and neck reconstruction via free flap surgery, with neck vessels versus superficial temporal vessels as recipient vessels.

Methods: The PubMed, Embase, and Scopus databases were systematically searched via the following keywords: ("superficial temporal" OR "temporal") AND ("free flap" OR "free tissue transfer") AND ("head and neck" OR "face"). The following data were extracted: first author, publication year, flap type, reconstruction region, concordant vein graft, recipient vessel, and postoperative complications, including thrombosis, partial necrosis, and flap failure.

Atypical Signs and Symptoms of Giant Cell Arteritis: A Systematic Review.

J Gen Intern Med

October 2024

Department of Ophthalmology and Vision Sciences, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada.

Article Synopsis
  • The study investigates atypical signs and symptoms of giant cell arteritis (GCA), which can delay treatment and lead to complications.
  • 429 research articles were analyzed, revealing that 18% of patients had only atypical features, while the majority also showed typical symptoms.
  • Atypical patients generally sought medical help earlier, but those with only atypical signs faced longer delays in starting treatment.*

Article Synopsis
  • Calciphylaxis leads to vascular calcification and blockage in small-to-medium-sized blood vessels, which can cause significant complications like vision loss.
  • A case study of a 64-year-old woman initially suspected to have anterior ischemic optic neuropathy due to giant cell arteritis (GCA) was later diagnosed with calciphylaxis, confirmed by histology.
  • Since calciphylaxis has no cure and requires different management than GCA, it's crucial for doctors to conduct thorough examinations and histopathological tests to differentiate between these conditions.

It is of critical importance to our understanding of Alzheimer's disease (AD) pathology to determine how key pathological factors are interconnected and implicated in nerve cell death, clinical symptoms, and disease progression. The formation of extracellular beta-amyloid (Aβ) plaques is the major pathological hallmark of AD and Aβ has been suggested to be a critical inducer of AD, driving disease pathogenesis. Exactly how Aβ plaque formation begins and how ongoing plaque deposition proceeds and initiates subsequent neurotoxic mechanisms is not well understood.

Article Synopsis
  • The study aimed to assess the effectiveness of vascular ultrasound (US) in detecting giant cell arteritis (GCA) before and after starting glucocorticoid (GC) treatment in patients new to the condition.
  • A total of 48 treatment-naïve patients underwent various imaging tests, and US sensitivity showed high initial rates, followed by a decrease in sensitivity at days 3 and 10 after GC treatment, particularly for temporal artery (TA) assessments.
  • Findings suggest a rapid reduction in vasculitic signs after 3 days of treatment, emphasizing the need for early US evaluation within this timeframe to ensure accurate GCA diagnosis.

Purpose Of Review: There have been advances in the diagnosis and treatment of giant cell arteritis (GCA) and polymyalgia rheumatica (PMR).

Recent Findings: Themes in PMR and GCA include classification criteria, ultrasound imaging of temporal and axillary arteries replacing biopsies for diagnosis of GCA, faster diagnosis and treatment with rapid access clinics for suspected GCA, and expanding treatment options with the goal of rapid suppression of inflammation and sparing steroids.

Summary: Treatment is aimed at suppressing inflammation quickly in both GCA and PMR.

Article Synopsis
  • - The hypoechoic halo is a common ultrasound finding in giant cell arteritis (GCA), but it can sometimes be misinterpreted due to arteriosclerosis.
  • - Researchers investigated the specific distribution of GCA lesions and introduced the "string of beads sign" to assess luminal irregularities in long-axis images.
  • - The study found that combining the string of beads sign with the hypoechoic halo improved diagnostic accuracy for GCA, showing a C-statistic of 1.00 compared to 0.89 for the halo alone.

  • The study aimed to assess the prevalence and characteristics of vasculitis in patients diagnosed with VEXAS syndrome, confirmed through UBA1 mutation.
  • A total of 89 male patients with an average age of nearly 67 years were evaluated, with 23.6% showing signs of vasculitis, predominantly small vessel types.
  • Findings suggest that VEXAS syndrome can present with vasculitis-related symptoms, including cranial issues that may resemble other conditions like giant cell arteritis, though significant large vessel involvement is infrequent.
