Methotrexate in ocular manifestations of Behcet's disease: a longitudinal study up to 15 years

Genetic Mutations Associated With TNFAIP3 (A20) Haploinsufficiency and Their Impact on Inflammatory Diseases

TNF-α-induced protein 3 (TNFAIP3), commonly referred to as A20, is an integral part of the ubiquitin-editing complex that significantly influences immune regulation, apoptosis, and the initiation of diverse immune responses. The A20 protein is characterized by an N-terminal ovarian tumor (OTU) domain and a series of seven zinc finger (ZNF) domains. Mutations in the TNFAIP3 gene are implicated in various immune-related diseases, such as Behçet's disease, polyarticular juvenile idiopathic arthritis, autoimmune thyroiditis, autoimmune hepatitis, and rheumatoid arthritis. These mutations can lead to a spectrum of symptoms, including, but not limited to, recurrent fever, ulcers, rashes, musculoskeletal and gastrointestinal dysfunctions, cardiovascular issues, and respiratory infections. The majority of these mutations are either nonsense (STOP codon) or frameshift mutations, which are typically associated with immune dysfunctions. Nonetheless, missense mutations have also been identified as contributors to these conditions. These genetic alterations may interfere with several biological pathways, notably abnormal NF-κB signaling and dysregulated ubiquitination. Currently, there is no definitive treatment for A20 haploinsufficiency; however, therapeutic strategies can alleviate the symptoms in patients. This review delves into the mutations reported in the TNFAIP3 gene, the clinical progression in affected individuals, potential disease mechanisms, and a brief overview of the available pharmacological interventions for A20 haploinsufficiency. Mandatory genetic testing of the TNFAIP3 gene should be performed in patients diagnosed with autoinflammatory disorders to better understand the genetic underpinnings and guide treatment decisions.

Decoding Behcet's Uveitis: an In-depth review of pathogenesis and therapeutic advances

Behcet's disease (BD) is a rare but globally distributed vasculitis that primarily affects populations in the Mediterranean and Asian regions. Behcet's uveitis (BU) is a common manifestation of BD, occurring in over two-thirds of the patients. BU is characterized by bilateral, chronic, recurrent, non-granulomatous uveitis in association with complications such as retinal ischemia and atrophy, optic atrophy, macular ischemia, macular edema, and further neovascular complications (vitreous hemorrhage, neovascular glaucoma). Although the etiology and pathogenesis of BU remain unclear, numerous studies reveal that genetic factors (such as HLA-B51), dysregulated immune responses of both the innate and adaptive immune systems, infections (such as streptococcus), and environmental factors (such as GDP) are all involved in its development. Innate immunity, including hyperactivity of neutrophils and γδT cells and elevated NK1/NK2 ratios, has been shown to play an essential role in this disease. Adaptive immune system disturbance, including homeostatic perturbations, Th1, Th17 overaction, and Treg cell dysfunction, is thought to be involved in BU pathogenesis. Treatment of BU requires a tailored approach based on the location, severity of inflammation, and systemic manifestations. The therapy aims to achieve rapid inflammation suppression, preservation of vision, and prevention of recurrence. Systemic corticosteroids combined with other immunosuppressive agents have been widely used to treat BU, and beneficial effects are observed in most patients. Recently, biologics have been shown to be effective in treating refractory BU cases. Novel therapeutic targets for treating BU include the LCK gene, Th17/Treg balance, JAK pathway inhibition, and cytokines such as IL-17 and RORγt. This article summarizes the recent studies on BU, especially in terms of pathogenesis, diagnostic criteria and classification, auxiliary examination, and treatment options. A better understanding of the significance of microbiome composition, genetic basis, and persistent immune mechanisms, as well as advancements in identifying new biomarkers and implementing objective quantitative detection of BU, may greatly contribute to improving the adequate management of BU patients.

Risk factors, clinical features and treatment of Behçet's disease uveitis

Behçet's disease is a systemic vasculitis frequently associated with intraocular inflammation. Recent findings identified independent clinical clusters in Behçet's disease, each involving distinct combinations of affected organs. Ocular Behçet's disease, mainly manifested as uveitis, is characterized as an independent cluster with a low likelihood of association with other system involvements, such as intestinal, cardiovascular, or central nervous system. A prevailing theory suggests that the pathogenesis of the disease is multifactorial, where a variety of genetic and infectious agents may interact with each other to cause the disease. Among sporadic cases, the human leukocyte antigen (HLA) genes, including HLA-B51, HLA-A26, HLA-B15, and HLA-B5701, have been found to be a key component conferring genetic susceptibility. Outside the HLA region, a set of susceptibility variants are identified, closely related to interleukin (IL)-23/IL-17 pathway, tumor necrosis factor (TNF) signaling, and pattern recognition receptor systems. Microbial infections, such as Streptococcus sanguinis, Mycobacterium tuberculosis, and Herpes simplex virus (HSV), are linked to play the triggering of disease in immunogenetically predisposed individuals. Clinically, due to the notable relapsing-remitting course of ocular Behçet's disease, the prevention of recurrent attack would be the primary treatment goal. Combination of corticosteroids and immunomodulatory drugs, such as anti-TNF agents, interferon, and conventional immunosuppressants (e.g. cyclosporine, azathioprine), have been the mainstream regimen for the disease. Future research may focus on comparing the effectiveness of immunomodulatory drugs and identifying the most suitable subgroups for a specific drug on the basis of the knowledge of the molecular heterogeneity of the disease.

Behçet's disease uveitis

Uveitis in Behçet's disease (BD) is frequent (40% of cases) and is a major cause of morbidity. The age of onset of uveitis is between 20 and 30 years. Ocular involvement includes anterior, posterior or panuveitis. It is non-granulomatous. Uveitis may be the first sign of the disease in 20% of cases or it may appear 2 or 3 years after the first symptoms. Panuveitis is the most common presentation and is more commonly found in men. Bilateralisation usually occurs on average 2 years after the first symptoms. The estimated risk of blindness at 5 years is 10-15%. BD uveitis has several ophthalmological features that distinguish it from other uveitis. The main goals in the management of patients are the rapid resolution of intraocular inflammation, prevention of recurrent attacks, achievement of complete remission, and preservation of vision. Biologic therapies have changed the management of intraocular inflammation. The aim of this review is to provide an update previous article by our team on pathogenesis, diagnostic approaches, identification of factors associated with relapse and the therapeutic strategy of BD uveitis.

Treatment Options in Pediatric Behçet's Disease

Behçet's disease is a rare and poorly understood vasculitis affecting blood vessels of all types and sizes. Uveitis and oral and genital ulcers represent the typical clinical triad. Populations along the ancient trading route connecting the Mediterranean basin with the Middle and Far East are most affected. Up to a quarter of the cases has a pediatric onset, typically around puberty. The aim of the treatment is early intervention to control inflammation, with symptom relief and prevention of relapses, damage, and complications. The heterogeneous clinical presentation often requires a multidisciplinary and tailored approach. Ocular, neurological, gastrointestinal, and vascular involvement is associated with a worse prognosis and needs more aggressive treatments. In young patients with expected prolonged disease, treatment should also focus on preventive measures and lifestyle advice. In recent years, the pharmacological armamentarium has grown progressively, although only a limited number of drugs are currently authorized for pediatric use. Most evidence for these drugs still derives from adult studies and experience; these are prescribed as off-label medications and are only available as adult formulations. Corticosteroids frequently represent the mainstay for the management of the initial acute phases, but their potential serious adverse effects limit their use to short periods. Different conventional disease-modifying anti-rheumatic drugs have long been used. Many other biologic drugs targeting different cytokines such as interleukin-1, interleukin-6, and interleukin-17 and treatments with small molecules including the phosphodiesterase 4 and Janus kinase inhibitors are emerging as novel promising therapeutic agents. In recent years, a growing interest has developed around anti-tumor necrosis factor agents that have often proven to be effective in severe cases, especially in those with a gastrointestinal and ocular involvement.

Current pharmacological solutions for Behçet's syndrome

INTRODUCTION

Behçet's syndrome (BS) has a heterogeneous clinical phenotype, and its clinical manifestations may respond differently to drugs commonly used to treat BS. The type, dose, and duration of immunomodulatory, immunosuppressive, and biologic agents should be tailored individually.

AREAS COVERED

We reviewed the literature for articles on BS management that were published until June 2022 and summarized the management options in BS for each type of organ involvement. We aimed to cover all currently available pharmacological agents used in BS, as well as surgical and interventional options, focusing on recent evidence.

EXPERT OPINION

The management aims in BS are to preserve function and quality of life and to avoid damage. The choice of treatment modalities depends on the organs that are actively involved, the severity of that involvement, and prognostic factors. A treat-to-attack strategy would help improve long-term outcomes in BS.

Adamantiades-Behçet's disease therapy - current treatment options and recommendations with regard to the COVID-19 pandemic

Adamantiades-Behçet's disease (ABD) is a chronic, idiopathic, relapsing immune-mediate disease that may involve multiple organs. It is characterized by recurrent oral and genital ulcers, skin lesions, ocular, gastrointestinal, vascular, neurological and joint involvement. It can lead to significant morbidity and mortality. Due to its heterogeneity in clinical findings and physiopathology, its treatment can be various as ABD manifestations in different organs may differently respond to the same drug. The cornerstone of therapy for inducing remission is systemic corticosteroid, whereas immunomodulatory and immunosuppressive agents such as colchicine, azathioprine, cyclosporine-A, interferon-alpha, and cyclophosphamide are used as steroid-sparing agents and to prevent relapses. For aggressive, refractory or frequently relapsing cases, tumor necrosis factor (TNF) alpha inhibitors (infliximab, adalimumab, etanercept) have been reported beneficial. Herein, we describe our experience of 7 patients treated with TNF-alpha inhibitors with recommendations regarding treatment choice during the COVID-19 era. This article is protected by copyright.

Angiographic patterns and temporal changes of arterial lesions in Behcet's disease

BACKGROUND

Behcet's disease (BD) can entail vascular involvement in various forms including aneurysm. We evaluated the angiographic patterns and changes in arterial lesions over time in BD patients with arterial involvement.

METHODS

We reviewed the medical records of BD patients diagnosed with arterial lesions between 1995 and 2018. Angiographic patterns were categorized as stenosis, occlusion, dilatation, or aneurysm. Patients were divided according to symptom duration (<5, 5-10, >10 years). Cox proportional-hazards model was used to evaluate the risk factors for vascular progression.

RESULTS

47 BD patients had arterial involvement in the following patterns: aneurysm (n = 31), stenosis (n = 17), dilatation (n = 13), and occlusion (n = 8). Aneurysm (70.8%) was the most common pattern in 24 patients with short (<5 years) symptom duration. Stenosis was more common (50.0%) in 12 patients with longer symptom durations (>10 years). In 23 patients with follow-up imaging (median, 5.7 years), eight (34.8%) developed 11 new lesions: stenosis (n = 5), dilatation (n = 1), and aneurysm (n = 5). One stenotic lesion progressed to occlusion, and two dilated lesions progressed to aneurysms. Lower extremity involvement and methotrexate use were associated with arterial progression, with hazard ratios of 5.716 (p = 0.029) and 0.101 (p = 0.049), respectively.

CONCLUSION

In BD patients with arterial involvement, aneurysm was the most common pattern in earlier stages of BD, while stenosis was more common in later stages of BD. Methotrexate use was associated with lower risk of arterial lesion progression.

Old and New Challenges in Uveitis Associated with Behçet's Disease

Behçet’s disease (BD) is a systemic vasculitis disease of unknown origin occurring in young people, which can be venous, arterial or both, classically occlusive. Ocular involvement is particularly frequent and severe; vascular occlusion secondary to retinal vasculitis may lead to rapid and severe loss of vision. Biologics have transformed the management of intraocular inflammation. However, the diagnosis of BD is still a major challenge. In the absence of a reliable biological marker, diagnosis is based on clinical diagnostic criteria and may be delayed after the appearance of the onset sign. However, therapeutic management of BD needs to be introduced early in order to control inflammation, to preserve visual function and to limit irreversible structural damage. The aim of this review is to provide current data on how innovations in clinical evaluation, investigations and treatments were able to improve the prognosis of uveitis associated with BD.

Long-term outcome and predictors of remission in Behçet's disease in daily practice

BACKGROUND

Many factors can influence the response to treatment and prognosis of Behçet's disease (BD). Identifying the predictors of response to treatment can improve the quality and decrease the cost of medical care. This analytical study was performed to identify factors affecting the remission and outcome in BD patients with long-term follow-up.

METHODS

A total of 245 BD patients aged over 16 years were followed for at least 12 months and visited at least three times a year were included. The outcome was assessed by the number of patients who were in sustained and long-term remission, had lost the primary criteria of BD for at least 12 months, were asymptomatic, and developed the sequela of disease or deceased. Sustained remission was defined as being in remission for at least six months. Long-term remission was defined as remission for ≥ 5 years.

RESULTS

Mean age and mean duration of follow-up were 35.1 ± 10.7 years and 92.3 months, respectively. At the end of follow-up, 63.2% of the patients lost the criteria of BD, 51.8% of the cases were in sustained remission, and 36.2% of them were asymptomatic. Predictors of sustained remission were adherence to therapy and treatment for more than six years. Having genital ulcers and treatment with methotrexate were associated with non-remission. Predictor of long-term remission was remission induction in the first two years of the treatment. Treatment with methotrexate was associated with non-remission. Poor outcome was observed in 31.8% of patients. Male sex, obesity, and having severe disease were the risk factors of poor outcome.

CONCLUSION

Achieving remission in BD is not inaccessible. Treatment with conventional and biologic disease-modifying antirheumatic drugs may cause sustained and long-term remission. Adherence to treatment, remission induction during the two years after the diagnosis and treatment for at least six years have significant role.

Management of Behcet's syndrome

Behcet's syndrome (BS) is a variable vessel vasculitis with heterogeneous clinical features. Skin, mucosa and joint involvement can cause impairment of quality of life but do not cause permanent damage whereas untreated eye, vascular, nervous system and gastrointestinal system involvement can cause serious damage and even death. Management of BS as a multidisciplinary team enables a faster and more accurate diagnosis and well-integrated treatment strategies. Corticosteroids are the mainstay of therapy. Colchicine, AZA, ciclosporin-A, cyclophosphamide, IFN alpha, and tumour necrosis factor alpha inhibitors are other agents used as induction and/or maintenance therapy. Although biologic agents have been increasingly used, there are still unmet needs. Head-to-head comparison studies of some therapeutic options (e.g. TNF inhibitors vs IFN alpha in uveitis) are required. Novel therapeutic agents in the pipeline could change the standard of care for BS in the future.

Behçet's disease uveitis: is there a need for new emerging drugs?

Introduction: Behçet's disease uveitis (BDU) is a potentially blinding disorder. Systemic treatment with disease-modifying anti-rheumatic drugs (DMARDs) is mandatory in patients with intraocular inflammation involving the posterior segment of the eye. Areas covered: This article discusses existing systemic treatment with corticosteroids and conventional and biologic DMARDs as well as adjunctive local therapy in BDU. An overview is provided for a wide range of biologic DMARDs that have shown promise or investigated in clinical trials. Most recently introduced biologic DMARDs and targeted synthetic DMARDs are also reviewed for their potential in the treatment of BDU. Expert opinion: The prognosis of patients with BDU has remarkably improved after the introduction of biologic DMARDs. An expanding therapeutic armamentarium will allow treatment of most refractory cases. The ultimate goal is to provide drug-free remission with preservation of 20/20 vision.

A 25-Year-Old Male with Orogenital Ulcers, Rash, and Difficulty Swallowing

A 25-year-old otherwise healthy male presented with new-onset odynophagia, rash, and orogenital ulcers. Despite treatment with antibiotics for presumed bacterial pharyngitis, the patient remained symptomatic, with abnormal vital signs and laboratory values. Upon dermatology consultation and histopathologic correlation, he was diagnosed with Behçet disease. Behçet disease is a rare rheumatologic condition that presents with recurrent oral ulcers and varying degrees of ophthalmic, neurologic, cardiac, and vascular disease. Given its protean nature, the treatment of Behçet disease is tailored to the patient's presentation and severity of organ involvement. Following treatment with colchicine and prednisone, the patient's symptoms improved rapidly.

Knitting the Threads of Silk through Time: Behçet's Disease-Past, Present, and Future

Behçet's disease (BD) is a chronic relapsing vasculitis that affects vessels of all types and sizes with a broad spectrum of phenotypic heterogeneity and complex immunopathogenesis. Efforts by the scientific community to resolve the unmet needs of BD and gaps in our knowledge have been hampered by considerable challenges that primarily relate to the rare nature of the disease in many parts of the world and its heterogeneity. Controversies remain in many aspects of the disease including the diagnostic criteria, immunopathogenesis and biomarker discovery, geographical variation, and therapeutic considerations. In this review, we highlight recent advances in our scientific understanding of BD, shed new insights into diagnostic and treatment strategies, and discuss residual gaps in our knowledge that will serve as the basis for current and future research.

Rheumatologists and Ophthalmologists Differ in Treatment Decisions for Ocular Behçet Disease

BACKGROUND

Ocular involvement in patients with Behçet disease represents a significant clinical morbidity in this disease, and the prevention of visual impairment is an important treatment goal. There are no randomized controlled trials for the treatment of ocular Behçet disease; however, clinicians must still make treatment decisions.

OBJECTIVES

The goals of this study were to describe the treatment preferences of rheumatologists and ophthalmologists for the treatment of ocular Behçet disease and to identify factors that influence these decisions.

METHODS

Eight hundred fifty-two rheumatologists and 934 ophthalmologists were surveyed via e-mail regarding their choice of therapy for a hypothetical patient with ocular Behçet disease. Respondents were asked to select first- and second-choice therapies and then reselect first and second choices assuming there would be no issues with cost or insurance prior authorization.

RESULTS

One hundred thirty two physicians (7.4%) who were willing to recommend treatment completed the survey: 68 rheumatologists and 64 ophthalmologists. The most common first-choice therapy for both specialties was a biologic agent. Significantly more rheumatologists than ophthalmologists chose methotrexate (P < 0.025) and azathioprine (P < 0.005) as their first-choice therapy. After assuming there were no concerns with cost or prior authorization, rheumatologists were still more likely to choose azathioprine compared with ophthalmologists (P < 0.02), and ophthalmologists were more likely to choose local steroid implants (P < 0.02). Both rheumatologists and ophthalmologists increased their choice of an anti-tumor necrosis factor agent when cost and prior authorization issues were removed (P < 0.0001 and 0.008, respectively).

CONCLUSIONS

Physician decision making is influenced by medical specialty and concerns regarding cost and prior authorization.

A Clinical Picture of the Visual Outcome in Adamantiades-Behçet's Disease

Adamantiades-Behçet's disease is a multisystemic vasculitis with multiorgan involvement. Ocular disorders occur often in this syndrome typically in the form of a relapsing-remitting panuveitis and vasculitis and can lead to blindness as one of its most disabling complications if left untreated. There are known risk factors related with the worst visual prognosis, which require early and intensive treatment in order to obtain a rapid suppression of inflammation and to prevent future relapses. The management strategy to avoid vision loss and blindness currently involves the use of local and systemic drugs including steroids and immunosuppressive and biologic agents. This review aims to demonstrate how the introduction and the use of biologic agents improves the visual outcome of patients with Adamantiades-Behçet's disease.

Autoimmune uveitis: clinical, pathogenetic, and therapeutic features

Autoimmune uveitis (AU), an inflammatory non-infectious process of the vascular layer of the eye, can lead to visual impairment and, in the absence of a timely diagnosis and suitable therapy, can even result in total blindness. The majority of AU cases are idiopathic, whereas fewer than 20 % are associated with systemic diseases. The clinical severity of AU depends on whether the anterior, intermediate, or posterior part of the uvea is involved and may range from almost asymptomatic to rapidly sight-threatening forms. Race, genetic background, and environmental factors can also influence the clinical picture. The pathogenetic mechanism of AU is still poorly defined, given its remarkable heterogeneity and the many discrepancies between experimental and human uveitis. Even so, the onset of AU is thought to be related to an aberrant T cell-mediated immune response, triggered by inflammation and directed against retinal or cross-reactive antigens. B cells may also play a role in uveal antigen presentation and in the subsequent activation of T cells. The management of AU remains a challenge for clinicians, especially because of the paucity of randomized clinical trials that have systematically evaluated the effectiveness of different drugs. In addition to topical treatment, several different therapeutic options are available, although a standardized regimen is thus far lacking. Current guidelines recommend corticosteroids as the first-line therapy for patients with active AU. Immunosuppressive drugs may be subsequently required to treat steroid-resistant AU and for steroid-sparing purposes. The recent introduction of biological agents, such as those targeting tumor necrosis factor-α, is expected to remarkably increase the percentages of responders and to prevent irreversible sight impairment. This paper reviews the clinical features of AU and its crucial pathogenetic targets in relation to the current therapeutic perspectives. Also, the largest clinical trials conducted in the last 12 years for the treatment of AU are summarized and critically discussed.

Biological treatments in Behçet's disease: beyond anti-TNF therapy

Behçet's disease (BD) is universally recognized as a multisystemic inflammatory disease of unknown etiology with chronic course and unpredictable exacerbations: its clinical spectrum varies from pure vasculitic manifestations with thrombotic complications to protean inflammatory involvement of multiple organs and tissues. Treatment has been revolutionized by the progressed knowledge in the pathogenetic mechanisms of BD, involving dysfunction and oversecretion of multiple proinflammatory molecules, chiefly tumor necrosis factor- (TNF-) α, interleukin- (IL-) 1β, and IL-6. However, although biological treatment with anti-TNF-α agents has been largely demonstrated to be effective in BD, not all patients are definite responders, and this beneficial response might drop off over time. Therefore, additional therapies for a subset of refractory patients with BD are inevitably needed. Different agents targeting various cytokines and their receptors or cell surface molecules have been studied: the IL-1 receptor has been targeted by anakinra, the IL-1 by canakinumab and gevokizumab, the IL-6 receptor by tocilizumab, the IL12/23 receptor by ustekinumab, and the B-lymphocyte antigen CD-20 by rituximab. The aim of this review is to summarize all current experiences and the most recent evidence regarding these novel approaches with biological drugs other than TNF-α blockers in BD, providing a valuable addition to the actually available therapeutic armamentarium.

Combination of pulse cyclophosphamide and azathioprine in ocular manifestations of Behcet's disease: longitudinal study of up to 10 years

AIM

Ocular lesions of Behcet's disease (BD) need aggressive treatment to prevent severe loss of vision or blindness. Cytotoxic drugs are the main therapeutic agents and the first line treatment. Retinal vasculitis is the most aggressive lesion of ocular manifestations and predicts a worse systemic outcome. We present here the outcome with a combination of pulse cyclophosphamide, azathioprine and prednisolone, on long-term usage, up to 10 years, on 295 patients (18 493 eye-months of follow-up).

METHODS

Cyclophosphamide was used as a 1-g monthly pulse for 6 months and then every 2-3 months as necessary. Azathioprine was used at 2-3 mg/kg daily. Prednisolone was initiated at 0.5 mg/kg daily. Upon the suppression of the inflammatory reaction, prednisolone was tapered gradually. Patients fulfilled the International Criteria Behcet's Disease (ICBD) and had active posterior uveitis (PU) and/or retinal vasculitis (RV). Visual acuity (VA), PU, RV and TADAI (Total Adjusted Disease Activity Index) were calculated.

RESULTS

Overall results: mean VA improved from 3.5 to 4.3 (P < 0.0001), 44% of eyes improved (95% CI = 40-50). Mean PU improved from 2.1 to 0.8 (P < 0.0001), 73% of eyes improved (95% CI = 69-78). Mean RV improved from 3.0 to 1.4 P < 0.0001), 70% of eyes improved (95% CI = 65-74). Mean TADAI improved from 29 to 18 (P < 0.0001), 72% of patients improved (95% CI = 66-77). The details of the longitudinal studies are given in the main article.

CONCLUSION

All parameters significantly improved. VA improvement was the least, mainly due to cataracts. This combination is the best treatment choice for retinal vasculitis before opting for biologic agents.
