Infection Screening and Vaccination of Adult and Pediatric Patients with Autoimmune Inflammatory Rheumatic Diseases: An Emirati Delphi Consensus.

Introduction: Patients with autoimmune and inflammatory rheumatic diseases (AIIRD) have an increased susceptibility to infections due to their compromised immune systems and the use of immunosuppressive therapies. Infections are a leading cause of morbidity and mortality in these patients, emphasizing the need for strategies such as infection control and vaccination to prevent avoidable harm to both patients and healthcare workers. This study aims to provide expert consensus on infection screening and vaccination guidelines for AIIRD patients.

Young Onset Chronic Inflammatory Back Pain: A Diagnostic Dilemma Between Axial Spondylitis and Diffuse Idiopathic Skeletal Hyperostosis.

Diffuse idiopathic skeletal hyperostosis (DISH) and axial spondyloarthritis (axSpA) share similarities in both clinical presentation and radiological findings, making the diagnostic process challenging. We report the case of a 30-year-old male with a longstanding history of back pain with an initial diagnosis of young-onset DISH. However, a diagnosis of axSpA was ultimately pursued based on his age and clinical presentation.

NETWORK ANALYSIS OF SINGLE-NUCLEOTIDE POLYMORPHISMS ASSOCIATED WITH ABERRANT INFLAMMATION IN TRAUMA PATIENTS SUGGESTS A ROLE FOR VESICLE-ASSOCIATED INFLAMMATORY PROGRAMS INVOLVING CD55.

Background: Critical illness stemming from severe traumatic injury is a leading cause of morbidity and mortality worldwide and involves the dysfunction of multiple organ systems, driven, at least in part, by dysregulated inflammation. We and others have shown a key role for genetic predisposition to dysregulated inflammation and downstream adverse critical illness outcomes. Recently, we demonstrated an association among genotypes at the single-nucleotide polymorphism (SNP) rs10404939 in LYPD4 , dysregulated systemic inflammation, and adverse clinical outcomes in a broad sample of ~1,000 critically ill patients.

From Sand to Excellence: A Deep Dive into Abu Dhabi's Rheumatology Landscape.

The Emirate of Abu Dhabi (AD) is the capital and largest emirate of the United Arab Emirates (UAE). The emirate's economic significance stems from non-oil and oil contributions to GDP. The 2022 GDP of Abu Dhabi was USD 230 billion.

A common single nucleotide polymorphism is associated with inflammation and critical illness outcomes.

Acute inflammation is heterogeneous in critical illness and predictive of outcome. We hypothesized that genetic variability in novel, yet common, gene variants contributes to this heterogeneity and could stratify patient outcomes. We searched algorithmically for significant differences in systemic inflammatory mediators associated with any of 551,839 SNPs in one derivation (n = 380 patients with blunt trauma) and two validation (n = 75 trauma and n = 537 non-trauma patients) cohorts.

A Tangled Autoimmune Trio: Multiple Sclerosis, Systemic Lupus Erythematosus and Antineutrophil Cytoplasmic Antineutrophil Cytoplasmic Antibody Vasculitis.

The coexistence of multiple autoimmune diseases in the same individual is unusual and has received little attention in the literature. We present a young female patient with multiple sclerosis, systemic lupus erythematosus, and biopsy-proven renal proteinase 3 antineutrophil cytoplasmic antibodyassociated vasculitis who responded well to intravenous rituximab clinically and serologically.

Comprehensive description of the prevalence, serological and clinical characteristics, and visceral involvement of systemic sclerosis (scleroderma) in a large cohort from the United Arab Emirates Systemic Sclerosis Registry.

Systemic sclerosis is an autoimmune condition characterized by a wide range of clinical presentations. Registries may serve to expand understanding about systemic sclerosis and aid in patient care and follow-up. The objective of this study was to analyze the prevalence of systemic sclerosis in a large cohort from the United Arab Emirates Systemic Sclerosis Registry and find the significant similarities and differences between the different subsets.

Plasma proteomics reveals early, broad release of chemokine, cytokine, TNF, and interferon mediators following trauma with delayed increases in a subset of chemokines and cytokines in patients that remain critically ill.

Severe injury is known to cause a systemic cytokine storm that is associated with adverse outcomes. However, a comprehensive assessment of the time-dependent changes in circulating levels of a broad spectrum of protein immune mediators and soluble immune mediator receptors in severely injured trauma patients remains uncharacterized. To address this knowledge gap, we defined the temporal and outcome-based patterns of 184 known immune mediators and soluble cytokine receptors in the circulation of severely injured patients.

Risk factors for lung function decline in systemic sclerosis-associated interstitial lung disease in a large single-centre cohort.

Objectives: The aim of this study was to identify risk factors of percent predicted forced vital capacity (ppFVC) decline in patients with SSc-associated interstitial lung disease (SSc-ILD).

Methods: We identified 484 patients with SSc who had HRCT Chest, of which 312 with ILD. Those with serial pulmonary function tests were included in a longitudinal analysis (n = 184).

Lipidomic signatures align with inflammatory patterns and outcomes in critical illness.

Alterations in lipid metabolism have the potential to be markers as well as drivers of pathobiology of acute critical illness. Here, we took advantage of the temporal precision offered by trauma as a common cause of critical illness to identify the dynamic patterns in the circulating lipidome in critically ill humans. The major findings include an early loss of all classes of circulating lipids followed by a delayed and selective lipogenesis in patients destined to remain critically ill.

Long-Term Efficacy and Safety of Omalizumab Monotherapy in a Patient With Normocomplementemic Urticarial Vasculitis.

Normocomplementemic urticarial vasculitis is a rare autoimmune disorder characterized by leukocytoclasia, fibrin deposits, and extravasated erythrocytes affecting multiple organ systems. Current treatment modalities, including corticosteroids and immunosuppressive agents, are of limited efficacy and an expansive side effect profile. Omalizumab has been reported to be effective in urticarial vasculitis, but its long-term effectiveness and tolerability have not yet been evaluated.

Consensus statements for pharmacological management, monitoring of therapies, and comorbidity management of psoriatic arthritis in the United Arab Emirates.

Objective: Psoriatic arthritis (PsA), a chronic inflammatory disease characterized by heterogeneous clinical manifestations, substantially impacts the quality of life of affected individuals. This article aims at developing consensus recommendations for the management of PsA and associated comorbidities and screening and monitoring requirements of PsA therapies in the United Arab Emirates (UAE) population.

Methods: An extensive review of present international and regional guidelines and publications on the pharmacological management, monitoring of therapies in the context of PsA was performed.

Predictors of not Achieving Remission or Low Disease Activity in Axial Spondyloarthritis Patients from Middle Eastern Countries: A Prospective, Multicenter, Real-world Study.

Objectives: We sought to identify the predictors of not achieving remission or low disease activity (LDA) among axial spondyloarthritis (SpA) patients in four Middle Eastern countries.

Methods: In this multicenter prospective real-world study, adult patients with axial SpA diagnosed clinically during January-June 2019, and who met the Assessment of SpondyloArthritis International Society classification criteria for axial SpA, were enrolled from the participating centers of four countries-Lebanon, Oman, Qatar, and the UAE. Patient demographics, disease history, comorbidities, treatment, and compliance data were obtained at baseline.

Objective: Psoriatic arthritis (PsA), a chronic inflammatory arthropathy, is often underdiagnosed in Middle Eastern countries, substantially impacting the treatment of affected individuals. This article aims to highlight current unmet clinical needs and provide consensus recommendations for region-specific evaluation methods and nonpharmacological therapies in the United Arab Emirates (UAE).

Method: An extensive literature review was conducted, focusing especially on global and regional guidelines for the evaluation and treatment of PsA.

Intravenous immunoglobulin in the management of refractory lupus profundus.

Lupus profundus, often known as lupus panniculitis, is a rare form of persistent cutaneous lupus erythematosus. It usually manifests as painful plaques or nodules that can ulcerate and cause atrophy and scarring. It may respond to topical treatments and antimalarials, although treatment might be difficult at times, necessitating immunosuppressive medications.

Primary Sjögren's Syndrome Presenting as Recurrent Ischemic Strokes.

Primary Sjogren's Syndrome (PSS) is an autoimmune exocrinopathy, with protean manifestations affecting multiple organ systems. Neurological manifestations are documented in about 20% of PSS cohorts in literature, with peripheral manifestations being commoner. Central nervous system manifestations of PSS (CNS-SS) encompass ischemic strokes, demyelinating lesions, aseptic meningitis, encephalitis, cerebellar ataxia, cognitive impairment and movement disorders.

The independent prognostic value of global epigenetic alterations: An analysis of single-cell ATAC-seq of circulating leukocytes from trauma patients followed by validation in whole blood leukocyte transcriptomes across three etiologies of critical illness.

Background: While bulk and single cell transcriptomic patterns in circulating leukocytes from trauma patients have been reported, how these relate to changes in open chromatin patterns remain unstudied. Here, we investigated whether single-cell ATAC-seq would provide further resolution of transcriptomic patterns that align with patient outcomes.

Methods: We performed scATAC-seq on peripheral blood mononuclear cells from four trauma patients at <4 h, 24 h, 72 h post-injury and four matched healthy controls, and extracted the features associated with the global epigenetic alterations.

Multi-omic analysis in injured humans: Patterns align with outcomes and treatment responses.

Trauma is a leading cause of death and morbidity worldwide. Here, we present the analysis of a longitudinal multi-omic dataset comprising clinical, cytokine, endotheliopathy biomarker, lipidome, metabolome, and proteome data from severely injured humans. A "systemic storm" pattern with release of 1,061 markers, together with a pattern suggestive of the "massive consumption" of 892 constitutive circulating markers, is identified in the acute phase post-trauma.
