Takayasu arteritis associated with autoimmune/inflammatory syndrome induced by adjuvants: a case-based review.

Takayasu's arteritis (TA) is a chronic granulomatous vasculitis that predominantly affects the aorta and its major branches. Despite advancements in the understanding of the pathogenic pathways of vascular inflammation, the etiology and predisposing factors of TA remain to be fully understood. In susceptible individuals, exposure to adjuvants may trigger, unlock or unmask an autoimmune disorder, presenting as non-specific constitutional symptoms or a fully developed autoimmune syndrome such as vasculitis. Here, we hypothesize that TA could be triggered by siliconosis, a subtype of the autoimmune/inflammatory syndrome induced by adjuvants (ASIA). ASIA, also known as Shoenfeld syndrome, encompasses a wide range of autoimmune and immune-mediated diseases resulting from dysregulation of the immune response after exposure to agents with adjuvant activity. This case report describes the development of large artery vasculitis, TA, in an individual one year following the placement of silicone breast implants. The patient initially presented with non-specific symptoms, and multiple imaging methods were employed, including ultrasound diagnostics, CT angiography, and 18-fluorodeoxyglucose positron emission tomography/CT. These techniques revealed vasculitic alterations in the carotid arteries and thoracic aorta. Initial treatment with glucocorticosteroids proved ineffective, prompting the addition of steroid-sparing immunosuppressive agents. Due to the distinct clinical symptoms, disease progression, implant-associated fibrosis, and resistance to therapy, the potential involvement of implants in the development of large-vessel vasculitis was considered, and a potential association with ASIA was postulated. Although there is limited evidence to support a direct link between adjuvants and the pathogenesis of TA, similarities in cellular immunity between the two conditions exist. The diagnosis of this complex and potentially debilitating condition requires a comprehensive clinical examination, laboratory evaluation, and instrumental assessment. This will aid in identifying potential contributing factors and ensuring successful treatment.

Heart failure caused by Takayasu's arteritis in the time of COVID-19: a case report.

The case of a 35-year-old female with heart failure is presented, where the symptoms overlap with the heterogeneous manifestations of coronavirus disease 2019 (COVID-19). Those similarities and a recent shift in priorities during the SARS-CoV-2 pandemic delayed the recognition of acute heart failure in this patient. During the differential diagnostic process, obliterative disease was discovered in the bilateral subclavian and right renal arteries, and the latter resulted in uncontrolled hypertension, which played a significant role in the development of heart failure. The aetiology of vascular alterations turned out to be Takayasu's arteritis. Diagnosing Takayasu's arteritis is typically not straightforward due to its nonspecific signs and symptoms. Therefore, it can be concluded from our case report that the rising incidence of COVID-19 and focus on ruling out infection can potentially defer alternative, but appropriate diagnostic tests, particularly for certain conditions like rare diseases. Early identification and intervention is especially important for treating acute heart failure, whereas delay increases the risk of severe complications and mortality.

The effect of COVID-19 pandemic in a large series of patients with Takayasu arteritis.

BACKGROUND: Patients with inflammatory rheumatic diseases faced several challenges during the COVID-19 pandemic. Uncertainties such as the lack of evidence regarding the use of immunosuppressive (IS) therapies and deferred patient care because of limited health resources affected negatively on many aspects of treatment decisions and routine follow-up of the patients. In this study, we aimed to investigate the prevalence and severity of SARS-CoV-2 infection, the impact of the pandemic on delays in routine clinical follow-up, changes in IS treatment, and COVID-19 vaccination status of patients with Takayasu arteritis (TAK). METHODS: The study was performed between July and September 2021. TAK patients who registered in our database were investigated with regards to the COVID-19 infection and vaccination status, delays in routine clinical visits, changes in their IS treatments, and flares during the pandemic. Physical examination, laboratory tests, and imaging of the patients were performed and ITAS2010 scores were calculated. RESULTS: There were 56 adult TAK patients (87.5% female and median age 47 years). A total of 44 (78.6%) patients experienced a delay with routine follow-up visits to their physicians and about 20% of patients stopped their antirheumatic treatments without consulting their physicians. Compared to the pre-COVID-19 pandemic, 16 (28.5%) patients flared. In total group, 13 (23.2%) patients had a mild COVID-19 infection and about 90% of the patients had received the COVID-19 vaccine. DISCUSSION: Deferred patient care and disease flares are the most significant problems in TAK patients during the pandemic. The risk of TAK flares may outweigh the risk of COVID-19 infection.

Updates in cutaneous manifestations of systemic vasculitis.

PURPOSE OF REVIEW: The main purpose of this review is to present newly reported cutaneous manifestations of systemic vasculitis, updates in investigations to verify systemic involvement in cases with cutaneous vasculitis and new therapeutic guidelines. The spectrum of COVID-19-related vasculitis is also covered. RECENT FINDINGS: Only a few reports highlighted new cutaneous presentations or associations with some systemic vasculitic entities. For example, the association of inflammatory disorders with Takayasu arteritis, the importance of considering Kawasaki disease in febrile children with erythema nodosum, the development of necrotic ulcers on fingers and toes in Behçet's disease and the possible presence of polyarteritis nodosa-like pathological features in vulvar ulcers of Behçet's disease. New attempts to classify cutaneous manifestations of giant cell arteritis (GCA) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and the diagnostic investigations for cutaneous vasculitis cases to verify systemic involvement are discussed. Treatment of systemic vasculitis with cutaneous vasculitis should be tailored according to disease status. A plethora of reports in the past 2 years focused on the broad spectrum of COVID-19 vasculitic manifestations. SUMMARY: Although newly reported cutaneous manifestations of systemic vasculitis are relatively uncommon, the plethora of reports in the past 2 years on COVID-19 vasculitis necessitates the expansion of the classification of vasculitis associated with probable cause to include severe acute respiratory syndrome coronavirus-2 (SARS-Cov-2) vasculitis.
