Abstract
Takayasu arteritis is a large vessel vasculitis of granulomatous nature and unknown aetiology affecting predominantly the aorta and its major branches, which may lead to ischaemic symptoms of many organs including the central nervous system. To decrease the risk of neurological complications and improve the quality of life, an arterial revascularisation may be necessary. The treatment options include pharmacotherapy as well as both open surgical and endovascular procedures, which has to be carefully chosen to obtain clinical success. There is an ongoing debate on the advantages, possibilities, and indications for implementing endovascular and open surgical methods, especially in high-risk patients. In this article we present our own experience in the treatment of an unusually complex and high-risk patient with multiple occlusion of supra-aortic branches, focusing on the technical aspects of the procedures and the decision-making process, as well as to confront with contemporary medical knowledge.

Abstract
Aim: To investigate the relation between polymorphisms in the interleukin 10 (IL)-10, tumor necrosis factor (TNF)-α, transforming growth factor (TGF)-β and interferon (IFN)-γ genes and Takayasu's arteritis in the Mexican population. Methods: A case-control study was performed to investigate the associations of IL-10, TNF-α, TGF-β and IFN-γ polymorphisms in a sample of 52 Takayasu's arteritis patients, diagnosed according to the criteria of the American College of Rheumatology and EULAR PRINTO criteria when the patients were under 18 years of age; 60 clinically healthy unrelated Mexican individuals by the 5' exonuclease TaqMan polymerase chain reaction. Polymorphic haplotypes were constructed after linkage disequilibrium analysis. Results: Significant differences were not found in the distribution for genotype and allele frequencies of the polymorphisms studied between healthy controls and Takayasu´s arteritis patients. Likewise, significant associations were not detected in the haplotype analysis with the different genes studied. Conclusions: These findings suggest that the polymorphisms in IL-10, TNF-α, TGF-β and IFN-γ might not contribute to the susceptibility of Takayasu´s arteritis in the Mexican population.

Abstract
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.

Abstract
OBJECTIVE/BACKGROUND Takayasu's arteritis (TA) is rare inflammatory large vessel form of vasculitis. The objective of this study was to evaluate experience in the management of TA patients and to identify the influence of inflammatory markers and clinical variables associated with disease progression, worsening ischaemic symptoms, and the need for interventions. METHODS Demographics, and laboratory and clinical variables in patients that required revascularisation procedures were compared with those who had adequate symptomatic control with medical management. Categorical data were analysed with Fisher's exact test, continuous variables with two-sample t test, and a life table analysis was used to study the recurrence of symptoms in intervened patients. RESULTS From January 1995 to May 2016, 47 patients (mean age 30 years; range 14-59 years) were managed; 44 (94%) were female. During the mean follow-up period of 120 months, 21 (45%) underwent 23 procedures (17 of these [74%] open, six [26%] endovascular). From the intervened group, eight (38%) patients presented with transient ischaemic attacks, five (24%) with renovascular hypertension, and four (19%) with upper extremity and four (19%) lower extremity claudication. Comparative analysis demonstrated that elevation of erythrocyte sedimentation rate (ESR) at the time of the diagnosis (revascularisation group: median value 28 mm/hour; medical management group: median value 15 mm/hour) was associated with progression of the disease, worsening symptoms, and subsequent need for intervention (p = .04). Active smoking was a factor connected with the need for revascularisation (p = .05). Immediate symptomatic improvement occurred in 19 (90%) patients that underwent surgical or endovascular revascularisation. CONCLUSION Patients with TA who underwent interventions had higher ESR at the time of diagnosis; this factor and active smoking were associated with progression of the disease and worsening ischaemic symptoms despite medical therapy. Revascularisation procedures are effective at relieving symptoms; lifelong surveillance is necessary.

Abstract
Background: Takayasu arteritis (TA) is a rare inflammatory arteriopathy of unknown etiology. The aim of this study was to investigate the genetic susceptibility to TA in a Chinese population. Methods: Four single nucleotide polymorphisms (SNPs) those locate in the IL12B region (rs56167332), the MLX region (rs665268), the FCGR2A/FCGR3A locus (rs10919543), and the HLA-B/MICA locus (rs12524487), associated with TA in different population, were genotyped in 123 Chinese TA patients and 147 healthy controls from January 2013 to August 2014. A Chi-square test was used to test for genotype/allele frequencies variants. Results: Among the four SNPs, rs10919543 was found to be significantly associated with TA in the studied population. The GG genotype of rs10919543 at the FCGR2A/FCGR3A locus is a high risk factor (odds ratio [OR] = 6.532, 95% confidence interval [CI] = 2.402 − 17.763, P < 0.001) for TA. Among TA patients, the level of eosinophil granulocytes (Eos) in the peripheral blood was observed to be higher in the GG group of rs10919543 (n = 23, Eos = 0.11 [0.08, 0.17] ×109/L) than the GA + AA group (n = 100, Eos = 0.08 [0.05, 0.13] ×109/L, P = 0.028). No correlation between the genotypes of the other three SNPs and TA patients was observed. Conclusions: Our findings revealed unique genetic pattern in Chinese TA patients that may be partly responsible for the higher risk of TA in this population. FCGR2A/FCGR3A-related immune disorder might contribute to the etiology of TA.

Abstract
An isolated stenotic or occluded segment of the descending thoracic and/or the abdominal aorta associated to Takayasu's arteritis (TA) is very uncommon and the clinical expression is known as "middle aortic syndrome." Manifestations depend on the lesion location, and may include hypertension originating from the aortic coarctation or renovascular, buttock, or lower extremity claudication and rarely chronic intestinal angina. We present 2 female patients with TA with occlusive lesions in the infrarenal aorta; both were treated with open surgical reconstruction of the affected segments. On follow-up, at 81 and 46 months, respectively, both patients remain symptoms free.

Abstract
Introduction HLA-B*51 and HLA-B*52 are two close human leukocyte antigen (HLA) allele groups with minor amino acid differences. However, they are associated with two different vasculitides (HLA-B*51 in Behçet's disease and HLA-B*52 in Takayasu's arteritis (TAK)) and with major clinical and immunological differences. In this study, we aimed to screen a large cohort of TAK patients from Turkey for the presence of HLA-B*51 and HLA-B*52 as susceptibility and severity factors. Methods TAK patients (n = 330) followed at a total of 15 centers were included in the study. The mean age of the patients was 37.8 years, and 86% were women. DNA samples from the patients and healthy controls (HC; n = 210) were isolated, and the presence of HLA-B*51 or HLA-B*52 was screened for by using PCR with sequence-specific primers. Results We found a significant association of HLA-B*52 with TAK (20.9% vs HC = 6.7%, P = 0.000, OR = 3.7, 95% CI = 2.02 to 6.77). The distribution of HLA-B*51 did not differ between TAK patients and HCs (22.7% vs 24.8%, OR = 0.9, 95% CI = 0.60 to 1.34). The presence of HLA-B*52 decreased in late-onset patients (> 40 years of age; 12.0%, P = 0.024, OR = 0.43, 95% CI = 0.20 to 0.91). Patients with angiographic type I disease with limited aortic involvement also had a lower presence of HLA-B*52 compared to those with all other disease subtypes (13.1% vs 26%, P = 0.005, OR = 0.43, 95% CI = 0.23 to 0.78). Conclusions In this study, the previously reported association of TAK with HLA-B*52 in other populations was confirmed in patients from Turkey. The functional relevance of HLA-B*52 in TAK pathogenesis needs to be explored further.

Abstract
We conducted a single-center retrospective study to compare the characteristics of Takayasu arteritis (TA) among white, North African, and black patients in a French tertiary care center (Hospital Pitié-Salpêtrière, Paris). Eighty-two patients were studied (82.9% female) during a median follow-up of 5.1 years (range, 1 mo to 30 yr). Among these 82 patients, 39 (47.6%) were white, 20 (24.4%) were North African, and 20 (24.4%) were black patients. Median age at diagnosis was 39.3 years (range, 14-70 yr) in white patients vs. 28.4 years (range, 12-54 yr) in North African (p = 0.02), and 28.0 years (range, 13-60 yr) in black patients (p = 0.08). Patients aged >40 years at TA onset were more frequently white than non-white (40.0% vs. 18.6%, p = 0.03). North African patients had more frequent occurrence of ischemic stroke (p = 0.03) and poorer survival (p = 0.01) than white patients. Type V of the Hata classification was the most frequent type among white (38.5%), North African (65.0%), and black patients (40.0%). Corticosteroids were used in 96.1% of patients. Fifty-three percent of white and North African patients, and 44% of black patients required a second line of immunosuppressive treatment (p = 0.60). Vascular surgical procedures were respectively performed in 46.1%, 50.0%, and 55.0% of white, North African, and black patients, p = 0.81. The 5-year and 10-year survival rates were 100% and 95.0%, respectively, in white patients; 67.4% at both 5 years and 10 years in North African patients; and 100% at both 5 years and 10 years in black patients. This study is one of the first direct comparisons of TA profiles among patients of distinct ethnic backgrounds. Our data support the idea that late-onset TA or an overlap between TA and large-vessel giant cell arteritis may be observed in white patients. North African patients have a higher occurrence of ischemic stroke and poorer survival than white patients.

Abstract
Takayasu's arteritis is an idiopathic chronic inflammatory disease affecting the aorta, its major branches and the pulmonary arteries. It leads to stenosis, occlusion, dilatation, and aneurysm formation in the involved vessels. Visceral arterial involvement occurs in 11 to 68% cases. Steno-obstructive lesions are most commonly seen and are usually symptomatic. Dilative and aneurismal lesions are uncommon and, when present, are usually clinically silent. Renal arteries are most commonly involved (24 to 68%), resulting in renovascular hypertension, whereas mesenteric arterial involvement is seen in 11 to 28% cases and is usually clinically silent. The assessment of disease activity is of utmost importance in its management as revascularization is best performed in the inactive phase. The disease activity can be assessed by clinical, biochemical, or radiological markers. The primary objectives of treatment include the control of disease activity by drug therapy, pharmacologic control of blood pressure (BP), supportive management and revascularization (surgical or endovascular) of the symptomatic ischemic territory. Surgical treatment is challenging due to the diffuse nature of the disease and involvement of adjacent aortic walls. It has a high incidence of anastomotic aneurysm formation (12 to 14%) and graft failure (20 to 40%) over time. Endovascular therapy (usually in the form of balloon angioplasty) has specific technical and procedural issues, but is safe and effective in the control of hypertension with success rates ranging between 80 to 96%. The overall complication rates are low. The cumulative 5-year patency rate for the management of renal artery stenosis is 67%. The use of stents is usually restricted as a bailout to treat obstructive dissection after angioplasty, due to a variety of reasons as their use may adversely affect the long-term outcome of treatment. Angioplasty is less effective in relieving obstruction in the mesenteric arteries and the outcomes are also infrequently reported.

Abstract
A possible relationship between Takayasu arteritis (TA) and Tuberculosis (Tb) has been suggested. Both diseases present similar chronic inflammatory lesions and occasionally granulomas on the arterial walls. The genetic relationship between these two diseases has not been explored before, however, both diseases have been associated with human leukocyte antigen (HLA) alleles. Therefore, the aim of the present study was to analyze the distribution of HLA-B alleles in TA (n = 40) and Tb (n = 34) patients and healthy controls (72 exposed and 99 nonexposed). HLA-B alleles were determined by reverse dot blot. The statistical methods used included the Chi(2), and odds ratio (OR) with 95% confidence intervals. In spite of the loose clinical relationship between TA and Tb, we did not detected any genetic relationship between them when the HLA-B alleles were analyzed in these groups of patients. On the contrary, we detected distinct specific HLA-B alleles for each disease. TA was characterized by HLA-B39, -B44, and -B52, pulmonary Tb by HL-B35 and extrapulmonary Tb by HLA-B39 and -B40. This preliminary study suggests a difference in the distribution of HLA-B alleles in patients with TA and Tb.

Abstract
Takayasu's arteritis is a rare, idiopathic, chronic inflammatory disease with cell-mediated inflammation, involving mainly the aorta and its major branches. It leads to stenosis, occlusion or aneurysmal degeneration of large arteries. The clinical presentation is characterised by an acute phase with constitutional symptoms, followed, months or years later, by a chronic phase in which symptoms relate to fibrosis or occlusion of vessels. Angiography is the gold standard for diagnosis and for topographical classification and it correlates with symptoms and prognosis. Here we focus on the pathophysiology, clinical and angiographical classification, diagnostic assessment and therapeutic approach of Takayasu's arteritis.

Abstract
Takayasu's Arteritis (TA) has been associated with the Major Histocompatibility Complex (MHC) genes; nevertheless, results in several populations have been heterogeneous. Studies both in Mexican and Asian populations suggest that residues at positions 63 (glutamic acid) and 67 (serine) of the HLA-B molecule could be the genetic markers for TA. In the present work, we analyzed the sequence of HLA-B alleles in 26 TA patients and 62 healthy controls. HLA-B subtyping analysis showed that all B52 alleles were B*5201, whereas only one HLA-B39 allele was B*3902. Sequencing of HLA-B alleles showed that 19 out of 26 patients studied (73.0%) presented at least an allele with glutamic acid at position 63 and serine at position 67. This condition was observed in only 21.0% of the healthy controls (pC = 0.00001, OR = 10.23). Out of the seven remaining patients, one presented glutamic acid at position 63 and four showed serine at position 67. Two patients (2/26 = 7.7%) and 24 healthy controls (24/62 = 38.7%) did not show similarity at the mentioned positions (pC = 0.016, OR = 0.13). These data corroborate the participation of positions 63 and 67 in the genetic susceptibility to TA and explain the high heterogeneity of alleles associated with the disease in several populations.

Abstract
Takayasu arteritis (TA) is a rare form of large-vessel, chronic, occlusive vasculitis. It involves mainly aorta and its main branches, causing stenosis and/or obstruction. Its frequency has been estimated at 2.9 cases per 1 million people. Epidemiologically, it is found principally in young female patients and is more prevalent in Asia and Latin America. When there is severe stenosis or occlusion in subclavian artery, the phenomenon of subclavian steal syndrome (SSS) occurs, which usually causes symptoms of the vertebrobasilar territory because blood supply to the arm is sustained by reversal of flow in ipsilateral vertebral artery. We describe a case of SSS thought to be due to TA in a Mexican woman. Doppler ultrasound of neck vessels showed retrograde flow in left vertebral artery during systole. Digital subtraction angiography confirmed 30% stenosis of left subclavian artery with filling of left vertebral artery in retrograde direction. In presenting this case, we carried out a brief review of TA, main features in imaging diagnosis of SSS, and the infrequently reported association of TA with SSS.

Abstract
Takayasu's arteritis (TA) is a chronic inflammatory disease of unknown etiology that can produce stenosis, occlusion, or aneurysmal degeneration of large arteries. TA occurs worldwide but disproportionately affects young females of Asian descent. A variable acute phase of largely constitutional symptoms is followed by a chronic phase in which symptoms related to arterial compromise predominate. Diagnosis is made using a combination of clinical and angiographic criteria. Initial therapy involves the use of corticosteroids to induce remission of acute phase activity, with the addition of cytotoxic medications for nonresponders. Angioplasty and stenting can be used in the treatment of shorter stenoses such as those encountered in the renal arteries. Surgical bypass is the preferred treatment of longer segment stenoses and occlusions. Bypass grafts should originate from unaffected arteries to ensure durable inflow. Endovascular therapy is effective initially but long-term durability data are lacking.

Abstract
In the present study we analyzed by PCR-SSO technique the HLA-B gene frequencies in 281 healthy individuals from four Mexican Amerindian populations (66 Mayos, 90 Mazatecans, 72 Nahuas and 53 Teenek). The most frequent alleles in all studied populations were HLA-B35, HLA-B39, and HLA-B40; however, some differences were observed between populations. The HLA-B35 allele was the most frequent in three of the four populations studied (Mayos, Nahuas and Teenek), whereas in Mazatecans the most frequent allele was HLA-B39. HLA-B40 presented frequencies higher than 10% in all groups. On the other hand, only Mayos presented an HLA-B51 gene frequency higher than 10%. When comparisons were made, important differences between groups were observed. The Teenek group presented an increased frequency of HLA-B35 when compared to Mazatecans and the HLA-B52 allele was increased in Nahuas and Teenek when compared to Mayos. An increased frequency of HLA-B39 was observed in Mazatecans when compared to Nahuas, Mayos and Teenek. Also, an increased frequency of HLA-B51 was observed in Mayos when compared to Mazatecans and Nahuas. These data corroborate the restricted polymorphism of HLA-B alleles and the high frequency of HLA-B35, HLA-B39 and HLA-B40 alleles in autochthonous American populations. In spite of the restriction in this polymorphism, differences in frequencies of HLA-B alleles could be helpful in distinguishing each of these populations.

Abstract
The past year has seen some notable publications in the field of vasculitis epidemiology. The appearance of reports from several different parts of the world has permitted comparisons to be made. In Europe, Wegener granulomatosis appears to be more common at high latitudes, whereas microscopic polyangiitis shows the reverse pattern. Kawasaki disease is most common in Japan. In China, the United States, and the United Kingdom, the incidence is lower, but the incidence appears to be increasing globally. Studies of infectious triggers continue to be disappointingly negative. Immunogenetic associations with cytokine polymorphisms are beginning to be reported.

Abstract
Takayasu arteritis is a well known yet rare form of large vessel vasculitis. This review details the history, clinical features, differential diagnoses, classification, and immunology of the disorder. Suppression of inflammation and preservation of vascular competence are the aims of treatment. As with any rare disease, randomised controlled treatment trials are either lacking or based on small patient numbers, making management decisions difficult. Current evidence based treatments are presented and discussed.

Abstract
The frequency of Takayasu's arteritis (TA) has been estimated to be 2.9 cases per 1 million people, with a female preponderance, although female-to-male ratio varies from different geographic areas. A high frequency of haplotype A24-B52-DR2 has been found in Japanese patients, without this association in other populations. TA has a striking predilection for the aortic arch and its branches. Evidence favors an autoimmune pathogenesis. Segmental inflammation (active and inactive lesions) may coexist. Due to its enhanced resolution, magnetic resonance imaging and magnetic resonance angiography eventually will replace catheterization angiography. Mortality reduction with glucocorticoid treatment has not been firmly established.
