Isolated arteritis of the lower limb vessels is an extremely rare condition. The use of modern vascular imaging techniques substantially facilitates and accelerates the diagnostics. In the isolated lower limb arteritis, it is always necessary to exclude Takayasu's and giant-cell arteritis. We present the case of a female patient with an isolated lower extremity arteritis without any other symptoms of systemic vascular damage or systemic autoimmune disease. Immunosuppressive therapy is obligatory in this case...

Objective: Takayasu's arteritis (TAK) is a chronic inflammatory vasculitis of the aorta and its major branches. In the present study, we aimed to evaluate the motion of the vascular wall and myocardial contractility by using a novel strain imaging method, velocity vector imaging (VVI), in patients with TAK. We also aimed to compare them with another inflammatory autoimmune disorder, systemic lupus erythematosus (SLE). Methods: We studied 33 patients with TAK, 18 patients with SLE, and 20 age- and sex-matched controls...

OBJECTIVE: To present and review the vascular consequences of arteritis in neurosarcoidosis. PATIENT AND METHODS: neurosarcoidosis is typically an inflammatory disorder of the meninges surrounding the brain and spinal cord. Although inflammation of small and medium sized vessels is seen pathologically and vasculitis is occasionally described, a large intracerebral arteritis has not previously been reported. A few case reports exist, however, which describe the vascular consequences of large vessel compromise in the disorder...

Rare autoimmune diseases are difficult to conduct researches in spite of present era with advanced scientific progress. Research using genetic approach is a promising way since genetic findings implicate causality of diseases. Still, there are multiple obstacles preventing genetic studies of rare diseases. Here, we list up the problems and propose solutions for them with detailed examples. The biggest problem is that it is difficult to collect a substantial number of DNA samples from patients with rare diseases...

A 63-year-old man presented with a 2-month history of progressive right-sided exophthalmos, painful ophthalmoplegia and fevers. As more features developed, he was diagnosed with giant cell arteritis then Tolosa-Hunt syndrome and transiently responded to corticosteroids. A bland cerebrospinal fluid and highly metabolically active brain (18 F)-fluoro-D-glucose-positron emission tomography suggested lymphoma. Biopsy of the mass showed sulphur granules with Gram-positive filamentous bacteria with Actinomyces -like colonies...

Giant cell arteritis (GCA) is an autoimmune vasculitis affecting large and medium-sized arteries. Ample evidence indicates that GCA is a heterogeneous disease in terms of symptoms, immune pathology and response to treatment. In the current review, we discuss the evidence for disease subsets in GCA. We describe clinical and immunological characteristics that may impact the risk for cranial ischemic symptoms, relapse rates and long-term glucocorticoid requirements in GCA patients. In addition, we discuss both proven and putative immunological targets for therapy in GCA patients with an unfavourable prognosis...

Introduction: Suspicion on the association between Takayasu Arteritis (TA) and Tubcerculosis (TB) has been in vogue for years. Prevalence of TB in TA is reported to be higher. We aimed to study innate immune responses in patients with TA on exposure to Trehalose-6,6-dibehenate (TDB), a synthetic analogue of Trehalose-6,6-Dimycolate (TDM, also known as mycobacterial cord factor) in comparison with healthy controls. Materials and Methods: Patients with type V TA, satisfying 1990 ACR criteria, and age and sex matched healthy controls were recruited...

Noninfectious gastrointestinal (GI) vasculopathic disorders are rare and are often overlooked in histopathologic examination or when forming differential diagnoses due to their rarity. However, involvement of the GI tract may lead to serious complications, including ischemia and perforation. Since awareness of the types of vasculopathy that may involve the GI tract is central to arriving at a correct diagnosis, we reviewed our institutional experience with GI tract vasculopathy in order to enhance diagnostic accuracy of these rare lesions...

OBJECTIVE/BACKGROUND: Although medical treatment has advanced, surgical treatment is needed to control symptoms of Takayasu's arteritis (TA), such as angina, stroke, hypertension, or claudication. Endovascular or open surgical intervention is performed; however, there are few comparative studies on these methods. This meta-analysis and systematic review aimed to examine the outcome of surgical treatment of TA. METHODS: A meta-analysis comparing outcomes of endovascular and open surgical intervention was performed using MEDLINE and Embase...

Once infected by viruses, cells can detect pathogen associated molecular patterns (PAMPs) on viral nucleic acid by host pattern recognition receptors (PRRs) to initiate the antiviral response. Porcine reproductive and respiratory syndrome virus (PRRSV) is the causative agent of porcine reproductive and respiratory syndrome (PRRS), characterized by reproductive failure in sows and respiratory diseases in pigs of different ages. To date, the sensing mechanism of PRRSV has not been elucidated. Here, we reported that the pseudoknot region residing in the 3' untranslated regions (UTR) of PRRSV genome, which has been proposed to regulate RNA synthesis and virus replication, was sensed as non-self by retinoic acid-inducible gene I (RIG-I) and Toll like receptor (TLR3) and strongly induced type I IFNs and interferon-stimulated genes (ISGs) in porcine alveolar macrophages (PAMs)...

PURPOSE OF REVIEW: Giant cell arteritis (GCA) is the most common systemic vasculitis. GCA is categorized as a granulomatous vasculitis of large and medium size vessels. Majority of the symptoms and signs of GCA result from involvement of the aorta and its branches intra- and extracranial. Temporal artery biopsy continues to be the cardinal diagnostic procedure despite new imaging modalities for diagnosing GCA with cranial involvement. Great advances in awareness have led to improvement in preventing irreversible vision loss due to early diagnosis...

OBJECTIVES: Giant cell arteritis (GCA) is a large-vessel vasculitis whose diagnosis is confirmed by temporal artery biopsy. However, involvement of large vessels, especially the aorta, can be shown by imaging, which plays an increasing role in GCA diagnosis. The threshold above which aortic wall thickening, as measured by computed tomography (CT), is considered pathological is controversial, with values ranging from 2 to 3 mm. This study assessed aortic morphology by CT scan and its diagnostic value in GCA...
