Heterogeneous Characteristics of Patients with Inflammatory Abdominal Aortic Aneurysm. Systematic Review of Therapeutic Solutions

BACKGROUND

Endovascular repair of inflammatory abdominal aortic aneurysms (IAAAs) has emerged as an alternative to open surgery, but direct comparisons are limited. The aim of the study was to compare clinical outcomes of endovascular and open repair for IAAA according with specific clinical characteristics.

METHODS

We performed a literature review of reports describing patients who had open or endovascular repair for IAAA. A literature search was performed in June 2022 by 2 investigators who conducted a review of papers reported in PubMed, Embase, MEDLINE, and Cochrane Database. The strings "Inflammatory aneurysm" and "Abdominal Aortic Aneurysms" were used. There was no language restriction and screened reports were published from March 1972 to December 2021. We identified 2,062 patients who had open (1,586) or endovascular repair (476) for IAAA. Primary outcomes were operative mortality and morbidity. Secondary outcomes were complications during follow-up (mean follow-up: 48 months). Propensity score matching was performed between patients who had open or endovascular surgery.

RESULTS

In Western countries, propensity-weighted postoperative mortality (in-hospital) (1.5% endovascular vs. 6% open) and morbidity rates (6% vs. 18%) were significantly lower in patients who had endovascular repair (P < 0.0001); patients with larger aneurysm (more than 7 cm diameter), signs of active inflammation, and retroperitoneal rupture of the aneurysm had better outcomes after endovascular repair than after open surgery. Hydronephrosis was present in 20% of the patients. Hydronephrosis regressed in most patients when signs of active inflammation were present suggesting an acute onset of the hydronephrosis itself (fever, elevated serum C Reactive Protein) either after endovascular or open surgery. Long-standing hydronephrosis as suggested by the absence of signs of active inflammation rarely regressed after endovascular surgery despite associated steroid therapy. During a mean follow-up of 48 months, propensity-weighted graft-related complications were more common in patients who had endovascular repair (20% vs. 8%). For patients from Asia, short-term and medium-term results were similar after open and endovascular repair. IAAAs related with aortitis were more common in Asia. In Western countries, IAAAs were commonly associated with atherosclerosis.

CONCLUSIONS

Patients with IAAA represent a heterogeneous population, suggesting biological differences from continent to continent; conservative therapy and endovascular or open surgery should be chosen according to the patient clinical condition. Endovascular repair presents advantages in patients with signs of active inflammation and contained rupture of the IAAA and larger aneurysms. Hydronephrosis, without signs of active inflammation, rarely regresses after endovascular repair associated with steroid therapy. Further studies are needed to establish the long-term results of endovascular repair.

Treatment of childhood-onset Takayasu arteritis: switching between anti-TNF and anti-IL-6 agents

OBJECTIVES

Biologics are new treatment alternatives in Takayasu arteritis (TA), although data in childhood are limited. The aim of this study was to share our experience in seven childhood-onset TA patients who received a TNF-α inhibitor (adalimumab) or an IL-6 receptor inhibitor (tocilizumab) and the effect of switching therapy.

METHODS

We retrospectively evaluated the medical treatment records of seven patients with TA, followed between August 2005 and January 2021 at the Pediatric Rheumatology Department of Hacettepe University Faculty of Medicine.

RESULTS

The median age of patients was 14 (IQR 4) years, and six were female. All of the patients had severe disease and high acute-phase reactants. The patients initially received only steroids or steroids+CYC. Prednisone was decreased, and biologic agents were started once the acute phase reactants decreased, and the Indian Takayasu Activity Score (ITAS) returned to normal. Initially, four patients received tocilizumab (TCZ) [median 25.5 (IQR 41) months] and three patients received adalimumab (ADA) [median 13 (IQR 31) months]. However, due to the progression of MR angiography findings or persistent elevation in acute-phase reactants, the biologic agents were switched from TCZ to ADA in four patients and from ADA to TCZ in three patients. The patients' median follow-up time after changing was 50 (IQR 77) months, and median ITAS was evaluated as '0' after 2 (IQR 4) months.

CONCLUSIONS

In conclusion, both TNF-α and IL-6 inhibitors are effective alternatives in treating patients with childhood-onset TA. However, prospective randomized controlled trials are needed for the comparison of their effectiveness.

Severe Aortic Regurgitation and Left Main Coronary Artery Ostial Stenosis in a 21-Year-Old Woman: What's Going On?

•

TA is a progressive, relapsing large-vessel vasculitis.

•

TA usually affects the aorta and its major branches.

•

TA can cause LMCA or ostial lesions in young adults.

•

Involvement of the aorta in TA can cause AR of varying degrees.

•

Surgical rather than percutaneous revascularization produces better results in TA.

The clinical characteristics of Chinese Takayasu's arteritis patients: a retrospective study of 411 patients over 24 years

BACKGROUND

We aimed to investigate the clinical characteristics of 411 Chinese Takayasu's arteritis (TAK) patients using a retrospective analysis.

METHODS

We retrospectively reviewed 810 medical charts of patients with a diagnosis of TAK who were admitted to Peking Union Medical College Hospital from 1990 to 2014. 411 patients with a complete dataset were finally included in the analysis. The demographic data, clinical features, angiographic patterns, and TAK-related surgical procedures were collected and analyzed.

RESULTS

The median age at disease onset was 23 (18, 30) years old, with a median disease duration of 21 (6, 60) months; 325 (79.1%) were female. The angiographic involvement pattern was type I in 91 (22.1%) patients, type IIa in 16 (3.9%) patients, type IIb in 16 (3.9%) patients, type III in 12 (2.9%) patients, type IV in 26 (6.3%) patients, and type V in 250 (60.8%) patients. Subclavian arteries (79.8%) were the most commonly involved, followed by carotid arteries (79.1%). The occurrence rate (4.1%) of aortic aneurysm in this study was low; 119 operations and interventions were performed. The most common cause of death in this study was heart failure.

CONCLUSION

Subclavian arteries, carotid arteries, and type V were the most frequently involved arteries and angiography pattern in this Chinese TAK study. The difference in angiographic features may lead to differences in clinical manifestations. Surgical operation and interventions should be performed at different stages of the disease course.

Primary angiitis of the central nervous system: a report of three cases from a single colombian center

The primary angiitis of the central nervous system (PACNS) is an entity with a very low incidence and prevalence. It is not clear why the inflammatory process of this entity is limited to the cerebral vasculature without systemic manifestations. Its clinical manifestations are very heterogeneous and make clinical diagnosis difficult. In most cases, a brain biopsy is required. Only the clinical suspicion and the ability to recognize the possible clinical and imagenological patterns of presentation make an accurate diagnosis possible. The vast majority of the treatment recommendations are given by series of case reports. The following paper described the clinical, imagenological, and histopathological characteristics of three Colombian patients with PACNS. The strategic therapeutic used in shown.

Development of outcome measures for large-vessel vasculitis for use in clinical trials: opportunities, challenges, and research agenda

Giant cell (GCA) and Takayasu's arteritis (TAK) are 2 forms of large-vessel vasculitis (LVV) that involve the aorta and its major branches. GCA has a predilection for the cranial branches, while TAK tends to affect the extracranial branches. Both disorders may also cause nonspecific constitutional symptoms. Although some clinical features are more common in one or the other disorder and the ages of initial presentation differ substantially, there is enough clinical and histopathologic overlap between these disorders that some investigators suggest GCA and TAK may be 2 processes within the spectrum of a single disease. There have been few randomized therapeutic trials completed in GCA, and none in TAK. The lack of therapeutic trials in LVV is only partially explained by the rarity of these diseases. It is likely that the lack of well validated outcome measures for LVV and uncertainties regarding trial design contribute to the paucity of trials for these diseases. An initiative to develop a core set of outcome measures for use in clinical trials of LVV was launched by the international OMERACT Vasculitis Working Group in 2009 and subsequently endorsed by the OMERACT community at the OMERACT 10 meeting. Aims of this initiative include: (1) to review the literature and existing data related to outcome assessments in LVV; (2) to obtain the opinion of experts and patients on disease content; and (3) to formulate a research agenda to facilitate a more data-based approach to outcomes development.

Retrospective evaluation of 22 patients with Takayasu's arteritis

Takayasu's arteritis (TA) is a rare, idiopathic, inflammatory, granulomatous vasculitis that affects the aorta and its primary branches. Clinical features and the pattern of arterial involvement show differences in different regions of the world according to ethnic influences. Our aim in this retrospective study was to evaluate the demographic, clinic, laboratory, and angiographic findings of 22 patients with TA followed by our clinic and also compare our results with series from the literature. The hospital files of the 22 patients followed by our clinic between 1998 and 2009 were retrospectively evaluated. We also compared our results with the series from the literature that we were able to reach by US National Library of Medicine, National Institute of Health. Gender distribution, age at diagnosis, and type of aortic involvement were similar with the study from Turkey. Different clinical manifestations of Takayasu's arteritis have been described in different ethnic groups. We also want to underline the coincidence of TA and other rheumatic diseases such as sarcoidosis, SLE, RA, and psoriatic arthritis, different from other published series.

Takayasu's arteritis: clinical features and outcomes of 125 patients in China

Takayasu's arteritis (TA) is a chronic inflammation that frequently involves the aorta and its major branches. The clinical features of TA vary in different ethnic populations. The objective of this study is to characterize the clinical features, angiographic findings, and response to treatment of patients with TA in Changhai Hospital, Shanghai, China. The hospital records of 125 patients diagnosed with TA were retrospectively evaluated. Eighty patients were followed for a median duration of 36 months. Females (86.4%) were most frequently affected. The mean age at onset was 26.9 years. Constitutional symptoms were present in only 38.4% of patients. The most common clinical finding was pulse deficit. Histological findings from 12 clinically inactive patients showed active lesions in 58.3%. Angiographic classification showed that type I was the most common, followed by type V and IV. Type I was more common in adult patients than in pediatric patients. Although immunosuppressive treatment induced remission in most patients, over 90% of those who achieved later remission relapsed. Both bypass procedures and angioplasty showed high rates of initial success, but restenosis occurred in 34.7% of bypass procedures and 77.3% of angioplasty procedures. Eight patients died during the follow-up period with the main cause of death being congestive heart failure. Constitutional symptoms were not frequent in our study. Correlation between the clinical assessment of disease activity and histologic findings is often poor in TA. Angiographic findings showed that type I was the most common in our study. Over the longer term, the outcomes of revascularization were superior to angioplasty.

Takayasu arteritis in France: a single-center retrospective study of 82 cases comparing white, North African, and black patients

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.

Are classification criteria for vasculitis useful in clinical practice? Observations and lessons from Colombia

INTRODUCTION

Idiopathic systemic vasculitis represents a group of clinical entities having non-specific etiology with the common characteristic of acute or chronic inflammatory compromise of the small and large vessels walls, associated with fibrinoid necrosis.

OBJECTIVES

To describe the most common inflammatory vascular diseases in a long historical cohort of patients from San Juan de Dios Hospital located in Bogota, Colombia using two different systems and a clinical histopathological correlation format, and to make a comparison between them.

METHODS

We reviewed all previously ascertained cases of vasculitis confirmed by biopsy processed between 1953 and 1990, and systematically collected data on all new cases of vasculitis from 1991 to 1997 at the Hospital San Juan de Dios (Bogota-Colombia). The cases were classified in accordance with the Chapel Hill Consensus criteria, and the system proposed by J.T. Lie.

RESULTS

Of 165,556 biopsy tissue specimens obtained during this period from our hospital, 0.18% had vasculitis, perivasculitis or vasculopathy. These included 304 histopathological biopsies from 292 patients. Cutaneous leukocytoclastic vasculitis (64 histological specimens) was the most frequently encountered type of "primary" vasculitis followed by thromboangiitis obliterans (38 specimens), and polyarteritis nodosa (24 specimens). Vasculitis associated with connective tissue diseases (33 specimens) and infection (20 specimens) were the main forms of secondary vasculitis, a category that was omitted from the Chapel Hill consensus report. We found that 65.8% of our histopathological diagnoses could not be classified according to the Chapel Hill classification, and 35.2% could not be classified according to the classification of Lie. Only 8.9% of cases remained unclassified by our system after clinical and histological correlation.

CONCLUSION

Current vasculitis classification schemes are designed for classification, rather that diagnosis of disease and do not adequately address some common forms of inflammatory vascular diseases, including those of infectious etiology and unusual etiology seen in clinical practice. Based on our clinical experience, we suggest a classification outline which practitioners can use which emphasizes correlation of the clinical picture to the histopathology findings for diagnosis and therapy, which may promote better clinical practice and standardization for clinical trials.

Takayasu's Arteritis presenting as a dissecting aortic aneurysm history: a case report

Introduction

Takayasu's Arteritis, formerly known as "pulseless disease", is a chronic idiopathic vasculitis which affects the large vessels in the body. First described in the 1800's, this rare condition is more commonly found in Asian women in their 40's. The aorta and its main branches are the primary vessels affected, with the most typical features reflected as ischemia or aneurysm formation. With Takayasu's Arteritis being a rare condition and its acute phase presentation often similar to other conditions, diagnosis is often difficult.

Case Presentation

A 48 year old Irish Caucasian female, who presented as a typical history of an aortic dissection (chest pain radiating to her back in an interscapular region and a systolic blood pressure differential of 50 mmHg between her right and left upper limbs), was investigated with a number of imaging modalities and diagnosed with Takayasu's Arteritis, involving arteries affecting a number of organs. She was treated as per protocol for Takayasu's Arteritis. A diagnosis of cervical cancer quickly followed.

Conclusion

This case report highlights that a differential diagnosis should never be dispelled based upon a "typical" history. The importance of modern day imaging techniques such as CT, MRI and angiography, can often be paramount to confirming a diagnosis and the extent of the pathology.

A possible link between Takayasu's Arteritis and gynaecological malignancies may exist.

Takayasu arteritis: clinical features and management: report of 272 cases

BACKGROUND

Takayasu's arteritis is a condition of unknown aetiology with an unpredictable natural history. Most of the literature available has originated from Asia, with a few contributions from Africa where the pattern of the disease may be different. This is a single institution's experience review.

METHODS

Data were obtained retrospectively from the angiographic and medical records of patients treated at Groote Schuur Hospital over the period 1952-2002. The criteria for inclusion were those proposed by the Aortitis Syndrome Research Committee of Japan and the American College of Rheumatology.

RESULTS

Two hundred and seventy-two patients were identified. The mean age at presentation was 25 years (range 14-66 years) and 75% were female. Only 8% were Caucasian. Hypertension was the most common presentation (77%) and was usually a consequence of renal artery stenosis or aortic coarctation. Cardiac failure was the most common problem. Cerebrovascular symptoms were recorded in 20%. Convincing evidence of tuberculosis was present in 20%. The entire aorta was involved in 70% of cases. Thirty per cent had aortic bifurcation involvement. Occlusions were noted in 93% and aneurysms in 46%. Vascular reconstruction was performed on 115 occasions in 99 patients, with an operative mortality of 4%. Cardiac failure was the usual cause of death. One hundred and six patients (39%) were followed for a minimum of 5 years. No further progression of disease was noted in 70 patients.

CONCLUSION

The natural history and prognosis of Takayasu's arteritis still remain poorly defined.

Takayasu arteritis with multiple intracranial aneurysms. A case report

SUMMARY

A rare case of multiple cerebral aneurysms associated with Takayasu aortitis is reported. Only seven cases have been reported so far, all of which are from Japan. This is the first case with this association being reported from India. A 50-year-old hypertensive woman developed sudden onset severe headache and loss of consciousness. CT scan revealed subarachnoid haemorrhage in the suprasellar cisterns and mild hydrocephalus. The patient on admission had a rebleed producing a massive subarachnoid haemorrhage. Angiogram revealed occlusion of bilateral vertebral arteries and right common carotid artery. The left carotid artery was ectatic with saccular aneurysms in the ophthalmic segment and communicating segment. Aortogram showed the radiological picture of Takayasu arteritis Type III. Surgical clipping of the aneurysms was performed. However, the patient developed a massive right cerebral infarct in the postoperative period following which she expired. Abnormal haemodynamics in the overloaded cerebral circulation rather than primary arteritic involvement of intracranial vessels appears to be the cause of aneurysm formation.

Multiple isolated aneurysms in a case of "burned out" Takayasu aortitis

Takayasu aortitis (TA) is a chronic inflammatory disease predominantly seen in young Asian women. The disease is idiopathic and largely affects the aorta and its major branches. The basic pathologic changes in TA are fibrosis and subsequent occlusion of the large arteries. TA is classically termed "pulseless" disease, with manifestations during the occlusive stage including limb ischemia, renovascular hypertension, and heart failure. Arterial dilation and aneurysm are largely unappreciated manifestations of TA, but they occur in as many as 32% of affected patients. We report chronic "burned out" TA in a 23-year-old Hispanic woman with isolated aneurysms of the descending thoracic aorta, abdominal aorta, and common iliac arteries, without occlusive disease.

Occlusive thromboaortopathy (Takayasu disease): clinical and angiographic features and a brief review of literature

The aim of this study was to evaluate the diagnostic criteria and angiographic classifications of Takayasu arteritis by presenting the clinical, angiographic, and prognostic findings and a prospective follow-up of 78 patients. Occlusive thromboaortopathy or Takayasu arteritis is a large vessel vasculitis. The disease is systemic with an autoimmune and genetic etiology. The complete clinical and angiographic manifestations are reported for 78 cases based on diagnostic criteria of the American College of Rheumatology with a mean 6 +/- 3.2 years follow-up. The mean age was 34.7 and female:male ratio was 3.6:1. According to National Institute of Health criteria, 61.5% of patients were in the acute phase of disease with systemic symptoms such as fever, weight loss, malaise, and elevated C-reactive protein levels. Immunologic markers, such as antinuclear antibody and antineutrophil cytoplasmic antibodies, were negative. The tuberculin test result was positive in 47%. Vascular bruit was present in 89%. Almost all patients had stenoses, occlusions, or aneurysmatic changes of the aorta and its main branches. Hypertension was detected in 58% and left ventricular hypertrophy was initially present in 22 (28%) patients. The angiographic manifestations were classified as type I, cervicobrachial type with 20 cases (25.6%); type II, thoracoabdominal type with 13 cases (16.6%); type III, peripheral type with 10 cases (12.8%); and type IV, generalized type with 35 cases (44.8%). The coronary arteries were involved in 6 cases, pulmonary arteries in 11 initially 5 in follow-up (16 cases), and renal arteries in 28 cases, respectively. A good correlation of the clinical manifestations and the prognosis was observed. During follow-up, five patients suffered from myocardial infarction, six had cerebrovascular accident, seven patients underwent aortic valve replacement, and six patients died (mortality rate, 7.6%). The specificity and sensitivity of diagnostic criteria were 94% and 76%, respectively. In contrast to ours and Nasu's classification in the new classification of Numano, some angiographic types and subtypes of Takayasu arteritis are not present in our patients.

Association of HLA-DRB1*1602 and DRB1*1001 with Takayasu arteritis in Colombian mestizos as markers of Amerindian ancestry

We performed HLA Class I and Class II typing in 16 patients (15 women, one man) with a confirmed diagnosis of Takayasu arteritis. We did not find any of the previously described associations with HLA-B52, and/or HLA-DRB1*1301 alleles. However, in our patients, HLA-DRB1*1602 and HLA-DRB1*1001 were significantly increased. The association of Takayasu arteritis with Amerindian and Asian HLA-DRB1 alleles (DRB1*1602 and DRB1*1001) in the Colombian mestizo patients reported here, and with HLA-B*3906 previously reported in Mexicans, suggest the possibility that some HLA and disease associations are markers for ethnicity of a population carrying a disease gene which is present in an admixed population with the disease.
