The early diagnosis of Takayasu arteritis (TAK) remains challenging when TAK-related pulmonary artery involvement occurs as an isolated or initial clinical manifestation. We describe the long-term course of a patient with isolated pulmonary TAK who was initially diagnosed with pulmonary arterial hypertension with in situ thrombus but was re-diagnosed following thromboendarterectomy surgery.

Project description:BackgroundUp to 50% patients with Takayasu arteritis have pulmonary artery involvement. Hence, the early identification of pulmonary artery involvement to facilitate prompt treatment is required.MethodsThis retrospective study was performed in patients diagnosed with Takayasu arteritis between January 2009 and January 2016. Pulmonary artery involvement was confirmed with computed tomographic pulmonary angiography. Images from transthoracic echocardiography in three windows (suprasternal right pulmonary artery long-axis view, parasternal aortic short-axis view, and subxiphoid view) were documented and analyzed.ResultsA total of 27 patients had Takayasu arteritis and pulmonary artery involvement. Characteristic changes identified by echocardiography included luminal medium-to-high echogenic signals, stenosis, and occlusion, as well as intimal thickening. Left pulmonary artery involvement was revealed in the parasternal aortic short-axis view. Right pulmonary artery involvement was best observed in the suprasternal right pulmonary artery long-axis view, with complementary views from the parasternal aortic short-axis and subxiphoid angles. Pulmonary trunk involvement was not observed in all three windows.ConclusionsTransthoracic echocardiography could be a useful noninvasive test to detect pulmonary artery involvement in patients with Takayasu arteritis.

Project description:BACKGROUND:This study was performed to analyze the clinical manifestations, imaging features, and prognosis of Takayasu's arteritis (TA) with pulmonary arteritis (PA). METHODS:In total, 51 of 815 patients with TA were diagnosed with PA at the Peking Union Medical College Hospital from 1986 to 2015. The patients' medical records and radiographic data were retrospectively reviewed. RESULTS:The patients comprised 39 women and 12 men with a median age of 33 years (range, 14-67 years). The most common symptoms were dyspnea (70.6%), cough (66.7%), hemoptysis (47.1%), and chest pain (45.1%). Computed tomography (CT) pulmonary angiography, pulmonary arteriography, and pulmonary perfusion imaging showed pulmonary artery stenosis or occlusion in 44 patients. A total of 82.4% of patients had lung parenchyma lesions on CT scans, indirectly indicating pulmonary artery involvement. Additionally, 58.8% of patients had pulmonary hypertension (PH) by echocardiography. Compared with the PH group, the non-PH group was characterized by a shorter disease duration; more symptoms such as fever, chest pain, and hemoptysis; an increased erythrocyte sedimentation rate; and a higher incidence of subpleural wedge-shaped shadows on chest CT (P < 0.05). The median follow-up period was 48 months (range, 1-212 months), and all three deaths occurred in the PH group. CONCLUSIONS:The clinical manifestations of TA with PA are nonspecific. PH often complicates PA and is associated with a poor prognosis. Early clinical manifestations such as repeated fever, chest pain, hemoptysis, and recurrence of subpleural wedge-shaped shadows on chest CT should arouse suspicion of PA in patients with TA and prompt further investigations. This may allow PA to be diagnosed before the occurrence of PH. TRIAL REGISTRATION:ClinicalTrials, NCT03189602. Date of registration: June 16, 2017. Retrospectively registered.

Project description:Takayasu arteritis is an idiopathic granulomatous vasculitis of the aorta and its main branches and it constitutes one of the more common vasculitides in children. Inflammation and intimal proliferation lead to wall thickening, stenotic or occlusive lesions, and thrombosis, while destruction of the elastica and muscularis layers originates aneurysms and dissection. Carotid artery tenderness, claudication, ocular disturbances, central nervous system abnormalities, and weakening of pulses are the most frequent clinical features. The diagnosis is usually confirmed by the observation of large vessel wall abnormalities: stenosis, aneurysms, occlusion, and evidence of increased collateral circulation in angiography, MRA or CTA imaging. The purpose of this revision is to address the current knowledge on pathogenesis, investigations, classification, outcome measures and management, and to emphasize the need for timely diagnosis, effective therapeutic intervention, and close monitoring of this severe condition.

Project description:A 54-year-old woman presented with an enlarging, pulsatile left neck mass and a history of Takayasu arteritis. She had seven prior cervical vascular reconstructions, including a prosthetic right-to-left carotid crossover, and left vertebral and subclavian bypasses done with saphenous vein. The skin of her neck was scarred and thin. The anastomotic pseudoaneurysms were resected, the left carotid bifurcation was reconstructed with the cryopreserved femoral artery because of the concern about wound healing, and the subclavian and vertebral vein grafts were reimplanted. Intraoperative management, clamp sites and sequence, manner of shunting, choice of conduit, and wound healing were important considerations.

Project description:BackgroundTakayasu arteritis (TA) is a large vessel vasculitis that can involve pulmonary arteries (PAs). We studied multiple clinical characteristics related to pulmonary artery involvement (PAI) in TA patients.MethodsWe enrolled 216 patients with TA from a large prospective cohort. PAI was assessed in each patient based on data from magnetic resonance angiography/computed tomography angiography. Pulmonary hypertension, cardiac function, and pulmonary parenchymal lesions were evaluated further in patients with PAI based on echocardiography, the New York Heart Association Functional Classification, and pulmonary computed tomography, respectively. These abnormalities related to PAI were followed up to evaluate treatment effects.ResultsPAI was detected in 56/216 (25.93%) patients, which involved the pulmonary trunk, main PAs, and small vessels in the lungs. Among patients with PAI, 28 (50%) patients were accompanied by pulmonary hypertension, which was graded as 'severe' in 9 (16.07%), 'moderate' in 10 (17.86%), and mild in 9 (16.07%). Twenty-six (46.43%) patients showed advanced NYHA function (III, 20, 35.71%; IV, 6, 10.71%). Furthermore, 21 (37.50%) patients presented with abnormal pulmonary parenchymal lesions in the area corresponding to PAI (e.g. the mosaic sign, infarction, bronchiectasis). During follow-up, two patients died due to heart failure and pulmonary thrombosis. In the remaining patients, the abnormalities mentioned above improved partially after routine treatment.ConclusionsPAI is common in TA patients. PAI can cause pulmonary hypertension, cardiac insufficiency, and pulmonary parenchymal lesions, which worsen patients' prognosis.

Project description:BackgroundTakayasu arteritis (TA) is a rare form of chronic inflammatory granulomatous arteritis of the aorta and its major branches. Late gadolinium enhancement (LGE) with magnetic resonance imaging (MRI) has demonstrated its value for the detection of vessel wall alterations in TA. The aim of this study was to assess LGE of the coronary artery wall in patients with TA compared to patients with stable CAD.MethodsWe enrolled 9 patients (8 female, average age 46±13 years) with proven TA. In the CAD group 9 patients participated (8 male, average age 65±10 years). Studies were performed on a commercial 3T whole-body MR imaging system (Achieva; Philips, Best, The Netherlands) using a 3D inversion prepared navigator gated spoiled gradient-echo sequence, which was repeated 34-45 minutes after low-dose gadolinium administration.ResultsNo coronary vessel wall enhancement was observed prior to contrast in either group. Post contrast, coronary LGE on IR scans was detected in 28 of 50 segments (56%) seen on T2-Prep scans in TA and in 25 of 57 segments (44%) in CAD patients. LGE quantitative assessment of coronary artery vessel wall CNR post contrast revealed no significant differences between the two groups (CNR in TA: 6.0±2.4 and 7.3±2.5 in CAD; p?=?0.474).ConclusionOur findings suggest that LGE of the coronary artery wall seems to be common in patients with TA and similarly pronounced as in CAD patients. The observed coronary LGE seems to be rather unspecific, and differentiation between coronary vessel wall fibrosis and inflammation still remains unclear.

Project description:Giant cell arteritis (GCA) and Takayasu Arteritis (TAK) are two systemic granulomatous vasculitides affecting medium- and large-sized arteries. Similarities in GCA and TAK regarding the clinical presentation, the systemic inflammatory response and the distribution of the arterial lesions, have triggered a debate over the last decade about whether GCA and TAK represent two different diseases, or are age-associated different clinical phenotypes of the same disease. On the other hand, there are differences regarding epidemiology, several clinical features (eg, polymyalgia rheumatica in GCA) and treatment. The aim of this review is to present the latest data regarding this question and to shed some light on the differences and similarities between GCA and TAK regarding epidemiology, genetics, pathogenesis, histopathology, clinical presentation, imaging and treatment. The existing data in literature support the opinion that GCA and TAK are different clinical entities.

Project description:Takayasu arteritis (TAK) is a rare systemic vasculitis that is characterized by granulomatous inflammation of the aorta and its major branches. The cellular and biochemical processes involved in the pathogenesis of TAK are beginning to be elucidated, and implicate both cell and antibody-mediated autoimmune mechanisms. In addition, the underlying etiology to TAK may be explained, at least in part, by a complex genetic contribution. The most well-recognized genetic susceptibility locus for the disease is the classical HLA allele, HLA-B*52, which has been confirmed in several ethnicities. The genetic susceptibility with HLA-B*52, as well as additional classical alleles and loci, implicate both HLA class I and class II involvement in TAK. Furthermore, genetic associations with genes encoding immune response regulators, pro-inflammatory cytokines and mediators of humoral immunity may directly relate to disease mechanisms. Non-HLA susceptibility loci that have been recently established for TAK with a genome-wide level of significance include FCGR2A/FCGR3A, IL12B, IL6, RPS9/LILRB3, and a locus on chromosome 21 near PSMG1. In this review, we present the complex genetic predisposition to TAK and discuss how recent findings identified potential targets in the pathogenesis and treatment of the disease.

Project description:Takayasu Arteritis (TAK) is a large-vessel vasculitis that preferentially involves the aorta and its primary branches. Cardiac involvement is frequent in TAK and is a major determinant of the patient's outcome. Glucocorticoids (GC) are the mainstay of therapy for TAK, with high doses of GC effective to induce remission. However, relapses are common and lead to repeated and prolonged GC treatments with high risk of related adverse events. Potential GC toxicity is a major concern, especially because patients with TAK are young and need to be treated for several years, often for the whole life. Conventional immunosuppressive drugs are used in patients with severe manifestations but present some limitations. New therapeutic approaches are needed for patients with refractory disease or contraindications to conventional therapies. Fortunately, major progress has been made in understanding TAK pathogenesis, leading to the development of targeted biotherapies. In particular, IL-6 and TNF-α pathways seems to be the most promising therapeutic targets, with emerging data on Tocilizumab and TNF inhibitors. On the other hand, new insights on JAK-Inhibitors, Rituximab, Ustekinumab and Abatacept have been explored in recent studies. This review summarizes the emerging therapies used in TAK, focusing on the most recent studies on biologics and analyzing their efficacy and safety.
