Giant cell arteritis (GCA) of the female genital tract is rare with only 30 cases, including this case, documented in the literature. We present a patient who had total abdominal hysterectomy and bilateral salpingo-oophorectomy for an ovarian cyst and on histologic examination GCA involving the arteries of the myometrium, cervical stroma, ovaries and tubes was unexpectedly discovered. Upon questioning of the patient and further investigations it became clear that the patient did have symptoms and signs suggestive of systemic GCA including fatigue, low-grade fever, weight loss and elevated erythrocyte sedimentation rate (ESR). Treatment with oral corticosteroids resulted in rapid and complete recovery. It is concluded that an incidental finding of GCA in the genitalia should alert the clinician to the possibility of systemic GCA. If upon questioning of the patient and further investigations the existence of systemic GCA is confirmed, treatment with corticosteroids should be considered.

Giant cell arteritis (GCA), a systemic vasculitis affecting large and medium-sized arteries, poses significant diagnostic and management challenges, particularly in preventing irreversible complications like vision loss. Recent advancements in artificial intelligence (AI) technologies, including machine learning (ML) and deep learning (DL), offer promising solutions to enhance diagnostic accuracy and optimize treatment strategies for GCA. This systematic review, conducted according to the PRISMA 2020 guidelines, synthesizes existing literature on AI applications in GCA care, with a focus on diagnostic accuracy, treatment outcomes, and predictive modeling.

Giant cell arteritis (GCA) is a primary systemic vasculitis affecting the elderly, characterized by a granulomatous vessel wall inflammation of large- and medium-sized arteries. The immunopathology of GCA is complex, involving both the innate and adaptive arms of the immune system, where a maladaptive inflammatory-driven vascular repair process ultimately results in vessel wall thickening, intramural vascular smooth muscle cell proliferation, neovascularization and vessel lumen occlusion, which can lead to serious ischemic complications such as visual loss and ischemic stroke. Over the past decade, microRNA (miRNA) dysregulation has been highlighted as an important contributing factor underlying the pathogenesis of GCA.

Systemic bile acid homeostasis plays an important role in human health. In this study, a physiologically based kinetic (PBK) model that includes microbial bile acid deconjugation and intestinal bile acid reuptake via the apical sodium-dependent bile acid transporter (ASBT) was applied to predict the systemic plasma bile acid concentrations in human upon oral treatment with the antibiotic tobramycin. Tobramycin was previously shown to inhibit intestinal deconjugation and reuptake of bile acids and to affect bile acid homeostasis upon oral exposure of rats.

Giant cell arteritis (GCA) is a relapsing large-vessel vasculitis with risk of serious ischemic manifestations including vision loss and vascular damage in the form of large-artery stenosis, aneurysms and dissections. Approximately 50% of patients treated with glucocorticoid (GC) monotherapy and 30% of patients receiving adjunctive therapy with tocilizumab experience disease relapses, often during the first 2 years after diagnosis. Although most relapses in GCA do not involve life- or organ-threatening presentations and can be controlled successfully, frequent relapses may lead to increased use of GC and consequent treatment-related morbidity, in addition to risk of further vascular damage.

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.
