We present the first case report of coronary-carotid artery collateral formation in Takayasu's arteritis. There was a vasculitic involvement of both subclavian and carotid arteries with critical stenosis; cerebral perfusion was supported with collaterals arising from the mesenteric arteries and coronary artery. <<b>Learning objective:</b> A case of coronary-carotid artery collateral formation in Takayasu's arteritis is presented. Such an angiographic finding has not been reported previously, and ...[more]

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:BackgroundVasculitides are commonly unrecognized causes of coronary stenosis and myocardial ischemia. We report on a 24-year old patient with Takayasu's arteritis who underwent urgent percutaneous coronary intervention, suffered from symptomatic restenosis of the left main coronary artery during standard immunosuppressive therapy.Case presentationA 24-year old woman was referred for coronary angiography because of typical progressive angina pectoris. On bicycle ergometry, there were both reproducible symptoms and deep ST segment depressions on precordial leads. Semi-selective angiography of the left coronary artery revealed high-grade ostial stenosis. Because of persistent angina pectoris and electrocardiographic signs of acute myocardial ischemia, immediate percutaneous coronary angioplasty with subsequent implantation of an everolimus-eluting stent was performed. This intervention was performed with excellent angiographic results. Because of several concomitant criteria including hypoechogenicity on postprocedural intravascular ultrasonography, the diagnosis of Takayasu's disease was made. The patient was treated with prednisolone and cyclophosphamide for 5 months. Because of recurrent angina pectoris, another coronary angiography was performed, which revealed high-grade in-stent-restenosis. Immunomodulatory therapy was switched to high-dose prednisolone and the anti-IL-6 receptor antagonist tocilizumab. The high-grade in-stent-restenosis persisted, and aortocoronary bypass graft surgery was performed with two saphenous vein grafts to the left anterior descending and circumflex artery. Since then, the patient has been doing well for 2 years.ConclusionIn cases of treatment refractoriness during standard immunosuppressive therapy, more recently developed biological compounds may offer an alternative strategy.

Project description:Purpose of reviewTakayasu's arteritis (TAK) is a large-vessel vasculitis with a chronic, indolent course affecting the aorta and its main branches. This review will describe the recent studies to develop validated outcome measures to assess TAK.Recent findingsTAK is traditionally assessed with a physician's global assessment including symptoms and signs of inflammation and vascular insufficiency, acute-phase reactants (APRs), and imaging including conventional digital subtraction angiography, computerized tomographic, and magnetic resonance angiography, and recently 18-FDG-PET. Recent attempts to develop a validated tool for disease assessment include the Indian Takayasu Clinical Activity Score (ITAS2010), which incorporates clinical signs and symptoms with APRs in a simplified and weighted adoption of the Birmingham Vasculitis Activity Score. Among biomarkers to assess clinical activity, pentraxin-3 is perhaps the most promising, but its validity and superiority against APRs in clinical practice need to be demonstrated. Patient-reported outcomes (PROs) are increasingly recognized as of substantial importance to measure in clinical trials; in addition to so-called 'generic' tools such as the SF-36 or measures of fatigue, disease-specific instruments would likely help capture aspects of TAK not measured by generic quality-of-life assessments or physician-based tools.SummaryAlthough outcome measures for TAK are not sufficiently validated, progress in the assessment of TAK is reflected in recent studies with new tools such as ITAS2010, new biomarkers, and a variety of PROs.

Project description:Background: Collateral artery growth, also termed arteriogenesis, occurs upon narrowing or occlusion of a major artery. To date, attempts to stimulate arteriogenesis in patients for therapeutic purposes have not been successful. Experimental models showed that circulating cells orchestrate arteriogenesis. In humans, a large heterogeneity exists in the arteriogenic response. We hypothesized that good arteriogenic responders (GARs) and bad arteriogenic responders (BARs) differ in gene expression profiles of circulating cells, thereby disclosing potential new therapeutic strategies for the stimulation of arteriogenesis. Methods: A total of 45 patients scheduled for percutaneous coronary intervention (PCI) for single-vessel coronary artery disease underwent intracoronary measurements of collateral flow index (CFI) to distinguish between GARs (CFI>0.21) and BARs (CFI≤0.21). Monocytes and CD34+ stem cells were collected from peripheral blood. A fraction of monocytes was further processed to obtain stimulated monocytes and macrophages. Whole genome transcriptome analysis was performed on all four cell types. Results: LPS-stimulated monocytes showed 244 genes differentially expressed (false discovery rate < 0.05) between GARs and BARs. Macrophage gene expression correlated with stimulated monocytes, while resting monocytes and stem cells revealed no differential gene expression. Stimulated monocytes from GARs showed a strongly attenuated response in several interferon- and apoptosis-related genes, which was corroborated at the protein level. Conclusions Circulating cells from GARs and BARs distinctively differ in their gene expression profiles upon stimulation. The reduced expression of interferon and apoptosis genes in GARs may lead to novel therapeutic approaches for the stimulation of collateral artery growth.

Project description:Thirty consecutive cases of Takayasu's arteritis (TA) admitted over a period of four years in a large referral hospital were analysed. The extent of aorta and its branches involvement was assessed by a Duplex Doppler study and aortography. The mean age of patients was 24.7 years with the male to female ratio of 1:1.2. The vascular involvement was, Type I (10%), Type II (40%) and Type III (50%). Renal artery (76.6%), Coeliac and superior mesenteric arteries (46.6%) and right common carotid artery (30%) were the commonly involved branches of aorta. Systemic features were seen in 25 per cent cases. Hypertension (83.3%), unequal pulses (80%) and arterial bruit (66.6%) were common clinical features. Stroke (20%), cardiac failure (10%) and renal failure(10%), were the complications seen. Hypertensive retinopathy was common, but Takayasu's retinopathy was not seen.

Project description:To compare patterns of arteriographic lesions of the aorta and primary branches in patients with Takayasu's arteritis (TAK) and giant cell arteritis (GCA).Patients were selected from two North American cohorts of TAK and GCA. The frequency of arteriographic lesions was calculated for 15 large arteries. Cluster analysis was used to derive patterns of arterial disease in TAK versus GCA and in patients categorised by age at disease onset. Using latent class analysis, computer derived classification models based upon patterns of arterial disease were compared with traditional classification.Arteriographic lesions were identified in 145 patients with TAK and 62 patients with GCA. Cluster analysis demonstrated that arterial involvement was contiguous in the aorta and usually symmetric in paired branch vessels for TAK and GCA. There was significantly more left carotid (p=0.03) and mesenteric (p=0.02) artery disease in TAK and more left and right axillary (p<0.01) artery disease in GCA. Subclavian disease clustered asymmetrically in TAK and in patients ?55 years at disease onset and clustered symmetrically in GCA and patients >55 years at disease onset. Computer derived classification models distinguished TAK from GCA in two subgroups, defining 26% and 18% of the study sample; however, 56% of patients were classified into a subgroup that did not strongly differentiate between TAK and GCA.Strong similarities and subtle differences in the distribution of arterial disease were observed between TAK and GCA. These findings suggest that TAK and GCA may exist on a spectrum within the same disease.

Project description:In the present study, we performed transcriptome expression analyses in three independent peripheral blood-derived monocyte subpopulations from patients with chronic coronary occlusions (CTO) and tested for arteriogenesis. Whole-genome mRNA expression analyses were performed on these three monocyte subpopulations, namely: (1) unstimulated-, (2) 3 hours LPS-stimulated-, (3) monocyte-derived macrophages. Whole-genome mRNA expression analysis amongst others confirmed increased expression of IFNbeta-regulated genes in patients with insufficient coronary collateralization (collateral flow index (CFI) ≤0.37 “nonresponders”), compared with patients having sufficient collateralization (CFI>0.37 “responders”).

Project description:We present an uncommon case of a 48-year-old female patient with symptomatic presentation of a severe aortic regurgitation with aneurysm of the ascending aorta and progressive dyspnea. Detailed investigation of laboratory tests and imaging identified Takayasu's arteritis (TA) as the underlying etiology. Computed tomography scan revealed complete occlusion of the right carotid artery as well as stenosis at the origins of left subclavian and vertebral arteries. In addition, cardiac magnetic resonance angiogram showed aneurysm at the proximal segment of right subclavian artery. Intervention with corticosteroids effectively diminished the need for immediate surgical intervention. Treating physicians should always consider differential diagnosis of TA in the presence of atypical clinical findings in all patients with cardiac problems especially when there is valve involvement.

Project description:Takayasu arteritis is a chronic vasculitis involving the aorta and its main branches, the pulmonary arteries, and the coronary tree, and needs to be considered in a young patient with angina, in particular when pulses are absent. This case illustrates the limitations of exercise testing in diagnosing the extent of coronary artery disease and the risks associated with coronary angiography in patients with inflammatory disease in the left main stem coronary artery. It also highlights the novel use of non-invasive scanning with positron emission tomography using 18-fluorodeoxyglucose in assessing remission from this disease. Revascularisation was performed with percutaneous transluminal coronary angioplasty and stenting as an emergency procedure, but treatment of the restenosis with directional atherectomy was based on a review of the available literature. The lymphocytic alveolitis seen in this patient has not been previously described in Takayasu's disease.
