Takayasu arteritis (TA) is a chronic inflammatory disease of large arteries which progressively develop stenosis, occlusion or aneurismal degeneration. Proinflammatory cytokines and, among these, tumor necrosis factor-alpha (TNF-alpha) are increased and play a pathogenetic role in the development of disease. Conventional therapy often fails to determine clinical remission and, in these cases, pathogenetic strategies with anti-TNF-alpha drugs have been proposed. Infliximab is a human-murine chimeric monoclonal antibody that specifically binds to and neutralizes soluble TNF-alpha. It is an effective treatment for rheumatoid arthritis, spondyloarthritis, Crohn's disease and ulcerative colitis and it has been recently proposed for the treatment of TA in patients refractory to conventional therapy. Here we report the case of a patient affected by Takayasu arteritis unresponsive to conventional therapy who was then treated with infliximab and obtained a clinical remission of the disease.

Vasculitides represent a range of disorders marked by inflammation of blood vessels, often posing significant diagnostic challenges due to their diverse clinical presentations and involvement of multiple organ systems. We present the case of a 26-year-old woman who arrived with hemoptysis and a background of exertional dyspnea, chest pain, and occasional visual disturbances. Initial investigations showed elevated perinuclear anti-neutrophil cytoplasmic antibodies (P-ANCAs) and myeloperoxidase antibodies (MPOs), indicative of microscopic polyangiitis (MPA).

Background: Takayasu arteritis (TAK) and giant cell arteritis (GCA), the most common forms of large-vessel vasculitis (LVV), can result in serious morbidity. Understanding the molecular basis of LVV should aid in developing better biomarkers and treatments.
Methods: Plasma proteomic profiling of 184 proteins was performed in two cohorts.

A 23-year-old man was diagnosed with Crohn's disease (CD) of the large intestine after colonoscopy revealed longitudinal ulcers, and pathology revealed non-caseating epithelioid cell granulomas and anal fistulas. The CD relapsed, and therefore prednisolone (PSL) and infliximab (IFX) treatment was initiated. The PSL was gradually tapered.

Objective: To report an unusual manifestation of normal tension glaucoma(NTG) in a young female as presenting feature of Takayasu arteritis (TA).
Methods: We present a case of a 24-year-old woman who was initially diagnosed with NTG, with characteristic optic disc and retinal nerve fiber layer (RNFL) changes, and corresponding visual field defects. Further evaluation with CT angiography revealed that the patient had newly diagnosed TA.

Divisions of Critical Care, Pulmonary and Sleep Medicine, Department of Internal Medicine, McGovern Medical School, The University of Texas Health Science Center (UTHealth), Houston, TX, USA.
Background And Objective: There are several benign processes that affect the mediastinum with considerable morbidity that may range from reactive entities to neoplastic disorders. This review article will focus on non-neoplastic benign mediastinal diseases which include large vessel vasculitis such as Takayasu and giant cell arteritis, mediastinal granulomas, fibrosing mediastinitis and mediastinal infections. These diseases can cause significant morbidity and mortality; therefore, we aim to familiarize readers with the pathophysiology, epidemiology and diagnosis of these mediastinal diseases and provide an update on the treatment options available.
