Wang J, Sun Y, Chen R, Meng D, Wei Y, Jiang L, Kong X. Pro-fibrotic effect of the susceptible gene PCSK5 in vascular fibrosis of Takayasu arteritis via TGF-β and SMAD3 signaling pathway activation. J Autoimmun 2024; 148:103277. [PMID: 38972101 DOI: 10.1016/j.jaut.2024.103277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Revised: 04/28/2024] [Accepted: 06/19/2024] [Indexed: 07/09/2024]
Abstract
BACKGROUND Vascular fibrosis directly causes vascular thickening in Takayasu arteritis (TAK), in which sustained transforming growth factor beta (TGF-β) activation is critical. Understanding TGF-β activation regulation and blocking it might yield a therapeutic effect in TAK. Proprotein convertase subtilisin/kexin type 5 (PCSK5) rs6560480 (T/C) is associated with TAK development. In this study, we assessed the association between the PCSK5 rs6560480 genotype and PCSK5 expression in TAK and explored its molecular role in TGF-β activation and vascular fibrosis development. METHODS In TAK patients, PCSK5 and TGF-β expression in plasma and aortic tissue was examined by ELISA and immunohistochemical staining, and PCSK5 rs6560480 was genotyped. The correlation between PCSK5 and extracellular matrix (ECM) expression was examined by Western blotting (WB) and immunohistochemistry staining. Detection by co-immunoprecipitation was performed to detect the interaction between PCSK5 and TGF-β in adventitial fibroblasts (AAFs). Downstream signaling pathways were detected by WB and validated with appropriate inhibitors. Potential immunosuppressive agents to inhibit the effects of PCSK5 were explored in cell culture and TAK patients. RESULTS Patients with PCSK5 rs6560480 TT patients had significantly higher PCSK5 levels and more thickened vascular lesions than patients with PCSK5 rs6560480 CT. PCSK5 expression was significantly increased in alpha smooth muscle actin (α-SMA)-positive myofibroblasts in TAK vascular lesions. Overexpressing PCSK5 facilitated TGF-β and downstream SMAD2/3 activation and ECM expression in AAFs and aorta in in-vitro culture. The mechanistic study supported that PCSK5 activated precursor TGF-β (pro-TGF-β) to the mature form by binding the pro-TGF-β cleavage site. Leflunomide inhibited PCSK5 and pro-TGF-β binding, decreasing TGF-β activation and ECM expression, which was also partially validated in leflunomide-treated patients. CONCLUSION The findings revealed a novel pro-fibrotic mechanism of PCSK5 in TAK vascular fibrosis via TGF-β and downstream SMAD2/3 pathway activation. Leflunomide might be anti-fibrotic by disrupting PCSK5 and pro-TGF-β binding, presenting a new TAK treatment approach.

Comparison of methotrexate and azathioprine as the first-line steroid-sparing immunosuppressive agents in patients with Takayasu's arteritis. Semin Arthritis Rheum 2024; 66:152446. [PMID: 38669786 DOI: 10.1016/j.semarthrit.2024.152446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 03/17/2024] [Indexed: 04/28/2024]
Abstract
BACKGROUND Immunosuppressive (IS) agents are recommended for the first-line treatment of patients with active Takayasu's arteritis (TAK) together with glucocorticoids (GCs). However, there is limited data comparing the efficacy and outcomes of different IS agents for this purpose. OBJECTIVES In this study, we aimed to compare the outcomes of two most frequently used first-line IS agents, namely methotrexate (MTX) and azathioprine (AZA) in TAK patients. METHODS TAK patients who received any IS agent in addition to GCs as the initial therapy were included in this multicentre, retrospective cohort study. Clinical, laboratory and imaging data of the patients were assessed. In addition, a matched analysis (cc match) using variables 'age', 'gender' and 'diffuse aortic involvement' was performed between patients who received MTX or AZA as the first-line IS treatment. RESULTS We recruited 301 patients (F/M: 260/41, mean age: 42.2 ± 13.3 years) from 10 tertiary centres. As the first-line IS agent, 204 (67.8 %) patients received MTX, and 77 (25.6 %) received AZA. Less frequently used IS agents included cyclophosphamide in 17 (5.6 %), leflunomide in 2 (0.5 %) and mycophenolate mofetil in one patient. The remission, relapse, radiographic progression and adverse effect rates were similar between patients who received MTX and AZA as the first-line IS agent. Vascular surgery rate was significantly higher in the AZA group (23% vs. 9 %, p = 0.001), whereas the frequency of patients receiving ≤5 mg/day GCs at the end of the follow-up was significantly higher in the MTX group (76% vs 62 %, p = 0.034). Similarly, the rate of vascular surgery was higher in AZA group in matched analysis. Drug survival was similar between MTX and AZA groups (median 48 months, MTX vs AZA: 32% vs 42 %, p = 0.34). IS therapy was discontinued in 18 (12 MTX, 6 AZA) patients during the follow-up period due to remission. Among those patients, two patients had a relapse at 2 and 6 months, while 16 patients were still on remission at the end of a mean 69.4 (±50.9) months of follow-up. CONCLUSIONS Remission, relapse, radiographic progression and drug survival rates of AZA and MTX were similar for patients with TAK receiving an IS agent as the first-line f therapy. The rate of vascular surgery was higher and the rate of GC dose reduction was lower with AZA compared to MTX at the end of the follow-up.

Abstract
OBJECTIVE This study aims to evaluate the effectiveness and safety of adalimumab (ADA) compared with leflunomide (LEF) in patients with Takayasu arteritis (TAK). METHOD A retrospective cohort study was performed with the following inclusion criteria: the fulfilment of the 2022 American College Classification/European Alliance of Associations for Rheumatology criteria for TAK, age ≥18 years, and written informed consent. Forty-four patients were treated with LEF (n=28) or ADA (n=16) therapy due to relapsing/refractory disease or toxicity from previous therapy. Patients were evaluated at baseline (T0), at a median of 7.0 months (T1) and at 15.0 months of follow-up (T2). Data regarding disease activity, daily dose of prednisone, side effects and angiographic progression were analysed. RESULTS LEF and ADA groups had similar features on the baseline visit. However, intravenous methylprednisolone was more frequently prescribed for the ADA group (p=0.019). On T1 and T2 visits, complete response rates were similar for ADA and LEF groups (75.0% and 88.5%; p=0.397 and 62.5% vs 78.3%; p=0.307), respectively. The differences remained non-significant after adjusting for baseline variables by propensity score matching. Although the ADA group had a higher median daily prednisone on visit T1 (p=0.004), it was similar on visit T2 (p=0.595). Similar rates of angiographic progression were observed in ADA and LEF groups (40% vs 25%; p=0.467). Mild-to-moderate adverse events were observed only in the LEF group (17.9%). CONCLUSION LEF and ADA had comparable outcomes after a median of 15.0 months of follow-up. However, withdrawal from therapy and mild-to-moderate adverse events were only observed in the LEF group.

Abstract
Takayasu's arteritis (TAK) is a chronic granulomatous inflammatory disease that involves aorta and its primary branches. It is characterized by wall thickening, stenosis/obliteration or aneurysm formation of the involved arteries. In order to standardize the diagnosis and treatment of TAK in China, a clinical practice guideline with an evidence-based approach is developed under the leadership of National Clinical Medical Research Center for Dermatologic and Immunologic Diseases (NCRC-DID). Eleven recommendations for 11 clinical questions that are important to the diagnosis and treatment of TAK are developed based on the latest evidence and expert opinions combined with real clinical practice in China.

Abstract
Giant cell arteritis (GCA) and Takayasu arteritis (TAK) are large-vessel vasculitides affecting the aorta and its branches. Arterial damage from these diseases may result in ischemic complications, aneurysms, and dissections. Despite their similarities, the management of GCA and TAK differs. Glucocorticoids are used frequently but relapses are common, and glucocorticoid toxicity contributes to significant morbidity. Conventional immunosuppressive therapies can be beneficial in TAK, though their role in the management of GCA remains unclear. Tumor necrosis factor inhibitors improve remission rates and appear to limit vascular damage in TAK; these agents are not beneficial in GCA. Tocilizumab is the first biologic glucocorticoid-sparing agent approved for use in GCA and also appears to be effective in TAK. A better understanding of the pathogenesis of both conditions and the availability of targeted therapies hold much promise for future management.

Abstract
OBJECTIVE To compare the clinical and angiographic responses of mycophenolate mofetil (MMF) versus methotrexate (MTX) in Takayasu arteritis (TAK). METHODS This was an open-label, outcome assessor-blinded trial. Adult patients with active TAK were randomized 1:1 to MMF 1 g twice daily or MTX 20 mg once weekly by a computer-generated program. All patients were started on 0.5 mg/kg of steroids with a predetermined tapering protocol. The primary outcome was the treatment response as defined by Indian Takayasu arteritis score at 9 months. The secondary end points included the time to first failure and angiographic progression. RESULTS A total of 52 patients (26 in each arm) were recruited. The rate of responders was 71.43% (15/21) in the MMF arm and 63.64% (14/22) in the MTX arm (P = .58). The median time to the first failure was 9 months (range: 3-9) and 4.5 months (range: 3-9) in the MMF and MTX arms, respectively (P = .052). In both groups, 15% of patients (n = 3) had a progressive disease in angiography. CONCLUSIONS The results showed numerically better outcomes favouring MMF, with a longer time to the first failure than MTX (9 months versus 4.5 months, P = .052). No significant difference was seen in the angiographic outcomes.

Abstract
Takayasu's arteritis (TAK) is a rare chronic granulomatous arteritis that mainly affects the aorta and its major branches. Coronary artery (CA) involvement can be observed in 10-25% of TAK patients. We report a 21-year-old young female who was previously diagnosed with TAK and severe left main coronary artery (LMCA) stenosis and underwent numerous percutaneous coronary interventions (PCIs) in our hospital due to in-stent restenosis (ISR). This time, an excimer laser coronary atherectomy (ELCA) and drug-coated balloon (DCB) dilation was taken at the LMCA for the ISR. The blood flow was smooth after the operation, and she was symptom-free after discharge. Unfortunately, 5 months later, severe intimal hyperplasia was still seen in the stent of LMCA and left anterior descending (LAD) coronary artery. A coronary artery bypass graft surgery (CABG) was performed, and she has been symptom-free ever since. ELCA plus DCB is one of the novel ways we first reported. However, ensuring long-term inflammation control is equally important to restore blood flow. The combination of revascularization and anti-inflammation/immunosuppression is recommended to improve the outcomes of TAK patients with CA involvements.

Abstract
PURPOSE OF REVIEW This article serves as an up-to-date examination of the latest findings in the field of paediatric large-vessel and medium-vessel vasculitis. RECENT FINDINGS Over the last 2 years and in the wake of SARS-CoV2 pandemic, a multitude of studies have increased our insight into these conditions. Although large-vessel and medium-vessel vasculitis are uncommon amongst children, they are a complex and multisystem with a constantly evolving landscape. Increasing numbers of reports from low-income and middle-income countries are shaping our understanding of the epidemiology of vasculitis in children. The influence of infectious disease and the microbiome are of particular interest in unravelling pathogenetic aspects. Improved understanding of the genetics and immunology offer opportunities for better diagnostic options and biomarkers of disease as well as targeted therapies. SUMMARY In this review, we address recent findings in epidemiology, pathophysiology, clinical findings, bio-markers, imaging and treatment that have the potential to offer better management solutions for these uncommon conditions.

Abstract
OBJECTIVE The search for new glucocorticoid-sparing disease-modifying anti-rheumatic drugs continues to be an unmet need in large vessel vasculitis (LVV). This report aims to assess the effectiveness and safety of leflunomide (LEF) in Takayasu arteritis (TA) and giant cell arteritis (GCA). METHODS We systematically reviewed the literature, searching for studies evaluating the efficacy of LEF in LVV. A meta-analysis was conducted using the random-effects method. RESULTS The literature search identified eight studies that assessed LEF in TAK and seven in GCA. All were uncontrolled observational studies with a high risk of bias, implying a low or very-low certainty of evidence. In TAK, the pooled proportion of patients achieving at least a partial remission was 75% (95% CI: 0.64-0.84), angiographic stabilization was observed in 86% (0.77-0.94) and relapses in 12% (0.05-0.21). The mean reduction in the prednisolone dose (MRPD) after LEF treatment was 15.7 mg/d (10.28-21.16). Adverse events were observed in 8% of patients (0.02-0.16). Comparison of LEF with methotrexate (MTX) or cyclophosphamide revealed LEF to be superior in terms of remission induction, relapse prevention, and tolerance. When compared with tofacitinib, both drugs demonstrated comparable efficacy. In GCA, the pooled proportion of patients achieving at least a partial remission was 60% (0.17-0.95). The MRPD after LEF treatment was 15.63 mg/d (1.29-32.55) and 53% of the patients were able to discontinue glucocorticoids (0.25 - 0.80). Relapses were observed in 21% of cases (0.14- 0.28) and adverse events in 28% (0.12-0.46). Comparison of LEF with MTX showed similar efficacy and tolerance. CONCLUSION LEF is well tolerated and might be effective for patients with TAK and GCA.

Abstract
IntroductionThe condition of refractory lupus nephritis (LN) negatively affects the prognosis and life expectancy of the patients, posing a challenge to manage in clinical. This interventional study evaluated the efficacy as well as safety of leflunomide in patients with refractory LN.MethodsTwenty patients with refractory LN were enrolled in this study. A daily dose of 20–40 mg of leflunomide was given to the patients orally. Meanwhile, immunosuppressives were withdrawn, and corticosteroids were gradually tapered. There was an average follow-up period of 3, 6, and 12 months for most patients while some were observed for as long as 24 months. We recorded biochemical parameters and side effects. We calculated the response rate using intention-to-treat analysis.ResultsEighteen patients (90%) completed the study. At 3 months, 80% (16/20) of the patients achieved more than a 25% decrease in 24-hour urine protein quantity. At 6 months, three patients (15%) achieved a partial response, and five patients (25%) achieved a complete response. However, by 12 months and 24 months, the complete response rate dropped to 15% and 20%, respectively. The objective responses were 30% (6/20), 40% (8/20), 40% (8/20), and 30% (6/20) at 3, 6, 12, and 24 months, respectively. Two patients withdrew from the study due to developing cytopenia and leucopenia.ConclusionIn patients diagnosed with refractory LN, our study shows that leflunomide could be a promising treatment option owing to its response rate and safety profile.

Abstract
Glucocorticoids are the cornerstone of therapy for all forms of vasculitis. However, glucocorticoid treatment carries with it the risk of glucocorticoid toxicity. Recent research efforts in vasculitis have emphasized investigation into strategies that reduce glucocorticoid exposure. These strategies include the adoption of rapid-acting steroid-sparing agents, reduced-dose glucocorticoid induction regimens, the early introduction of steroid-sparing agents for maintenance therapy, and the extension of maintenance therapy to minimize glucocorticoid exposure associated with disease relapse. These are critical advances to move us toward the goal of glucocorticoid-free treatment of vasculitis. The evidence supporting each of these strategies and directions for future research are explored.

Abstract
Background Takayasu arteritis (TAK) is an immune-induced granulomatous vasculitis that occurs primarily in young Asian women. Our previous cohort studies have indicated that leflunomide (LEF), which can lead to rapid induction and might be a promising alternative treatment for TAK. Objectives To compare the efficacy and safety of LEF versus placebo combined with prednisone for active TAK in a Chinese population. Design This will be a multicenter, randomized, double-blinded controlled trial aiming to recruit 116 TAK patients with active disease. This study will last 52 weeks. Methods and analysis Participants will be assigned randomly to the LEF intervention arm or placebo control arm at a 1:1 ratio. Initially, LEF combined with prednisone will be given to the intervention arm and a placebo tablet combined with prednisone will be given to the placebo arm. At the end of week 24, subjects who achieved clinical remission or partial clinical remission will proceed to maintenance therapy with LEF to the end of week 52; those who did not achieve clinical remission or partial clinical remission in the LEF intervention arm will drop out from the study, and those in the placebo control arm will switch to LEF treatment to week 52. The primary endpoint will be the clinical remission rate of LEF versus placebo at the end of week 24. The secondary endpoints will be the time to clinical remission, mean dose of prednisone, disease recurrence, time to recurrence, adverse events, as well as clinical remission in subjects who switched from the placebo control arm to LEF therapy after week 24. Intention to treat will be the primary analysis. Discussion This is the first randomized double-blinded placebo-controlled trial to clarify the efficacy and safety of LEF in treating active TAK. The results will provide more evidence for TAK management. Registration ClinicalTrials.gov identifier: NCT02981979.

Abstract
Takayasu arteritis (TA or TAK) is a chronic large vessel vasculitis with predilection to affect the aorta and its branches. The new 2022 ACR/EULAR classification criteria for Takayasu arteritis incorporated imaging characteristics as an absolute requirement. ESR and CRP fails in accuracy as disease activity markers. Pentraxin 3 appears to be a relatively superior biomarker, which correlates with ITAS 2010 as per several studies. PET-CT is also increasingly being studied for assessing disease activity with variable results. The management of TAK involves use of steroids with upfront steroid sparing immunosuppressive agents. MMF is one such conventional DMARD/immunosuppressant with good efficacy and better safety profile, as reported in various cohort studies. Tocilizumab is proved to be a rapid remission inducing agent in refractory Takayasu arteritis in observational studies. TNF inhibitors in many uncontrolled studies showed good responses, and there is a need for good RCTs for confirmation. JAK inhibitors have also been used with success in a few reports.

Efficacy and safety of tofacitinib versus leflunomide with glucocorticoids treatment in Takayasu arteritis: A prospective study. Semin Arthritis Rheum 2022; 55:152018. [PMID: 35523066 DOI: 10.1016/j.semarthrit.2022.152018] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 04/05/2022] [Accepted: 04/25/2022] [Indexed: 12/25/2022]
Abstract
To investigate the efficacy and safety of leflunomide (LEF) versus tofacitinib (TOF) in Takayasu arteritis (TAK) patients. Sixty-seven active patients were recruited from an ongoing observational TAK cohort, including 35 patients treated with glucocorticoids (GCs) and LEF and 32 patients treated with GCs and TOF. The observation period was 12 months. The effectiveness rate (ER), remission rate, inflammatory parameters reduction, vascular imaging changes, GCs tapering, disease relapse and side-effects were evaluated between two groups. These aspects were also assessed separately among treatment-naïve or -refractory patients. The ER at 6 and 12 months was 88.57% (31/35) vs. 87.50% (28/32) (p = 1.00) and 71.43% (25/35) vs. 71.88% (23/32) (p = 1.00) in the LEF and TOF group. The percentage of patients with persistent remission from 6th to 12th months and GCs≤7.5 mg/day at 12 months was higher in TOF group (15 (46.88%) vs. 6 (17.14%) p = 0.02). The relapse prevalence was 6 (17.14%) and 7 (21.88%) (p = 0.76), respectively. Erythrocyte sedimentation rate (ESR) was decreased significantly at 6 months in both groups (p<0.05), whereas C-reactive protein (CRP) level was reduced significantly at 6 months only in the TOF group (p = 0.007). The proportion of patients with imaging improvement was higher in the TOF group (eight (25.00%) and two (5.71%), p = 0.04). Side-effect prevalence was higher in the LEF group (11 (31.43%) vs. 3 (9.38%), p = 0.04). In conclusion, LEF and TOF were comparable for TAK treatment. TOF might be a potential agent to maintain disease remission at a low dose of glucocorticoids in TAK.

Abstract
The pharmacotherapy of Takayasu arteritis (TAK) with disease-modifying anti-rheumatic drugs (DMARDs) is an evolving area. A systematic review of Scopus, Web of Science, Pubmed Central, clinical trial databases and recent international rheumatology conferences for interventional and observational studies reporting the effectiveness of DMARDs in TAK identified four randomized controlled trials (RCTs, with another longer-term follow-up of one RCT) and 63 observational studies. The identified trials had some concern or high risk of bias. Most observational studies were downgraded on the Newcastle-Ottawa scale due to lack of appropriate comparator groups. Studies used heterogenous outcomes of clinical responses, angiographic stabilization, normalization of inflammatory markers, reduction in vascular uptake on positron emission tomography, reduction in prednisolone doses and relapses. Tocilizumab showed benefit in a RCT compared to placebo in a secondary per-protocol analysis but not the primary intention-to-treat analysis. Abatacept failed to demonstrate benefit compared to placebo for preventing relapses in another RCT. Pooled data from uncontrolled observational studies demonstrated beneficial clinical responses and angiographic stabilization in nearly 80% patients treated with tumour necrosis factor alpha inhibitors, tocilizumab or leflunomide. Certainty of evidence for outcomes from RCTs ranged from moderate to very low and was low to very low for all observational studies. There is a paucity of high-quality evidence to guide the pharmacotherapy of TAK. Future observational studies should attempt to include appropriate comparator arms. Multicentric, adequately powered RCTs assessing both clinical and angiographic responses are necessary in TAK.
