Review
Viral anterior uveitis (VAU) needs to be suspected in anterior uveitis (AU) associated with elevated intraocular pressure, corneal involvement, and iris atrophic changes. Common etiologies of VAU include herpes simplex, varicella-zoster, cytomegalovirus, and rubella virus. Clinical presentations can vary from granulomatous AU with corneal involvement, Posner-Schlossman syndrome, Fuchs uveitis syndrome, and endothelitis. Due to overlapping clinical manifestations between the different viruses, diagnostic tests like polymerase chain reaction and Goldmann-Witmer coefficient analysis on the aqueous humor may help in identifying etiology to plan and monitor treatment.

Review
Little is known regarding anterior uveitis (AU), the most common ocular disease associated with cytomegalovirus (CMV) infection in immunocompetent populations. CMV AU is highly prevalent in Asia, with a higher incidence in men. Clinically, it manifests mainly as anterior chamber inflammation and elevated intraocular pressure (IOP). Acute CMV AU may resemble Posner-Schlossman syndrome with its recurrent hypertensive iritis, while chronic CMV AU may resemble Fuchs uveitis because of its elevated IOP. Without prompt treatment, it may progress to glaucoma; therefore, early diagnosis is critical to prognosis. Knowledge regarding clinical features and aqueous humor analyses can facilitate accurate diagnoses; so, we compared and summarized these aspects. Early antiviral treatment reduces the risk of a glaucoma surgery requirement, and therapeutic effects vary based on drug delivery. Both oral valganciclovir and topical ganciclovir can produce positive clinical outcomes, and higher concentration and frequency are beneficial in chronic CMV retinitis. An extended antiviral course could prevent relapses, but should be limited to 6 months to prevent drug resistance and side effects. In this review, we have systematically summarized the pathogenesis, clinical features, diagnostic and therapeutic aspects, and immunological mechanisms of CMV AU with the goal of providing a theoretical foundation for early clinical diagnosis and treatment.

Review
Behçet's syndrome is a variable vessel vasculitis with multi-system involvement that shows important heterogeneity among patients regarding demographic features, organ manifestations, frequency and severity of relapses, disease course, response to treatment and prognosis. This heterogeneity has made it difficult to interpret and compare the results of studies, to standardise disease assessment and to develop management strategies. Several new studies have been published during the previous year exploring the epidemiology, pathogenesis, clinical manifestations, diagnosis, and management of Behçet's syndrome. The aim of this review is to provide an overview of the most relevant recent research in Behçet's syndrome from a critical perspective.

Human leucocyte antigen B*27 (HLA-B*27) is strongly associated with inflammatory diseases of the spine and pelvis (for example, ankylosing spondylitis (AS)) and the eye (that is, acute anterior uveitis (AAU)). How HLA-B*27 facilitates disease remains unknown, but one possible mechanism could involve presentation of pathogenic peptides to CD8 T cells. Here we isolated orphan T cell receptors (TCRs) expressing a disease-associated public β-chain variable region-complementary-determining region 3β (BV9-CDR3β) motif from blood and synovial fluid T cells from individuals with AS and from the eye in individuals with AAU. These TCRs showed consistent α-chain variable region (AV21) chain pairing and were clonally expanded in the joint and eye. We used HLA-B*27:05 yeast display peptide libraries to identify shared self-peptides and microbial peptides that activated the AS- and AAU-derived TCRs. Structural analysis revealed that TCR cross-reactivity for peptide-MHC was rooted in a shared binding motif present in both self-antigens and microbial antigens that engages the BV9-CDR3β TCRs. These findings support the hypothesis that microbial antigens and self-antigens could play a pathogenic role in HLA-B*27-associated disease.

Review
There has been steady progress in understanding the pathogenesis, clinical features, and effective treatment of acute anterior uveitis (AU) over the past 5 years. Large gene wide association studies have confirmed that AU is a polygenic disease, with overlaps with the seronegative arthropathies and inflammatory bowel diseases, associations that have been repeatedly confirmed in clinical studies. The role of the microbiome in AU has received increased research attention, with recent evidence indicating that human leukocyte antigen B27 (HLA B27) may influence the composition of the gut microbiome in experimental animals. Extensive clinical investigations have confirmed the typical features of acute AU (AAU) and its response to topical, regional and systemic immunosuppressive treatment. Increased understanding of the role of cytokines has resulted in studies confirming the value of anti-cytokine therapy [anti-tumor necrosis factor (anti-TNF) and interleukin 6 (IL-6) therapy] in severe and recurrent cases of AAU, particularly in subjects with an associated spondyloarthopathy (SpA) and in juvenile idiopathic arthritis (JIA)-associated AAU.

Review
Psoriatic arthritis is a systemic autoimmune disease, in which a characteristic heterogeneous inflammatory involvement of entheses and both peripheral and axial joints tends to be associated with different clinical features, in particular skin or nail psoriasis, but also inflammatory bowel diseases, or acute anterior uveitis. Patients with PsA are at higher risk of developing comorbidities, in particular metabolic syndrome, with a significant impact on their quality of life. Although the advanced knowledge in the pathogenetic mechanisms of PsA helped in developing an abundant therapeutical armamentarium, the available drugs might still show a suboptimal efficacy. However, the frontier of "personalised medicine" could promote further future improvement in the quality of care of patients. In this paper we reviewed the literature on PsA of 2020 and 2021 (Medline search of articles published from 1st January 2020 to 31th December 2021).

American Journal of Ophthalmology Aug 2021To determine classification criteria for Behçet disease uveitis. (Comparative Study)
Comparative Study
PURPOSE
To determine classification criteria for Behçet disease uveitis.
DESIGN
Machine learning of cases with Behçet disease and 5 other panuveitides.
METHODS
Cases of panuveitides were collected in an informatics-designed preliminary database, and a final database was constructed of cases achieving supermajority agreement on the diagnosis, using formal consensus techniques. Cases were split into a training set and a validation set. Machine learning using multinomial logistic regression was used on the training set to determine a parsimonious set of criteria that minimized the misclassification rate among the intermediate uveitides. The resulting criteria were evaluated on the validation set.
RESULTS
One thousand twelve cases of panuveitides, including 194 cases of Behçet disease with uveitis, were evaluated by machine learning. The overall accuracy for panuveitides was 96.3% in the training set and 94.0% in the validation set (95% confidence interval 89.0, 96.8). Key criteria for Behçet disease uveitis were a diagnosis of Behçet disease using the International Study Group for Behçet Disease criteria and a compatible uveitis, including (1) anterior uveitis; (2) anterior chamber and vitreous inflammation; (3) posterior uveitis with retinal vasculitis and/or focal infiltrates; or (4) panuveitis with retinal vasculitis and/or focal infiltrates. The misclassification rates for Behçet disease uveitis were 0.6% in the training set and 0% in the validation set, respectively.
CONCLUSIONS
The criteria for Behçet disease uveitis had a low misclassification rate and seemed to perform sufficiently well for use in clinical and translational research.

Review
Non-infectious uveitis (NIU) is a serious sight-threatening condition whose pathogenesis is often autoimmune in nature. It may manifest in any age group, though adults aged 20-50 are the group most often affected. It causes 5-10% of visual impairment worldwide. The epidemiology of some specific uveitis diseases varies worldwide, because they are influenced by genetic, environmental and socioeconomic factors. It can occur only in the eye or as a symptom of a systemic condition. The most common cause of NIU is HLA-B-27-associated anterior uveitis (4-32%). The standard treatment for NIU is a local, topical and systemic steroid therapy in combination with immunomodulatory therapy. However, recently, a new drug - adalimumab, which is a tumor necrosis factor α (TNF-α) inhibitor - was approved by FDA in the treatment of NIU and is increasingly used to treat various conditions. Adalimumab has been proven in many studies to be safe and effective in the treatment of NIU associated with diverse systemic diseases.

Review
This critical review of studies on Behçet's syndrome published during 2022 includes studies on epidemiology, patients' perspective, pathogenesis, diagnosis, clinical features and management. Studies on pathogenesis included potential biomarkers mostly related to macrophages, neutrophil and cytokine balance, new GWAS and polymorphism studies, and studies on miRNAs and long non-coding RNAs. Clinical studies showed that application of pneumococcal vaccine to the prick site increased the sensitivity and specificity of the pathergy test and the prevalence of AA amyloidosis had decreased over the years. Studies on management indicated that more data are needed to understand the effect of apremilast on BS manifestations other than oral ulcers, and new BS manifestations may develop during treatment with infliximab. Other biologics and Jak inhibitors might be an option for patients who are refractory to TNF-α inhibitors. Moreover, endovascular repair of arterial aneurysms might be an alternative to open surgery.
