Temporal trends in COVID-19 outcomes in people with rheumatic diseases in Ireland: data from the COVID-19 Global Rheumatology Alliance registry.

Objectives: Although evidence is accumulating globally, data on outcomes in rheumatic disease and COVID-19 in Ireland are limited. We used data from the COVID-19 Global Rheumatology Alliance (C19-GRA) to describe time-varying COVID-19 outcomes for people with rheumatic disease in Ireland.

Methods: Data entered into the C19-GRA provider registry from Ireland between 24 March 2020 and 9 July 2021 were analysed.

Behçet syndrome.

Behçet syndrome is a systemic vasculitis with an unknown aetiology affecting the small and large vessels of the venous and arterial systems. The presence of symptom clusters, regional differences in disease expression and similarities with, for example, Crohn's disease suggest that multiple pathological pathways are involved in Behçet syndrome. These disease features also make formulating disease criteria difficult.

Comparing the clinical profile of adults and children with Behçet's syndrome in the UK.

Objectives: Behçet's syndrome (BS) is a rare multi-system inflammatory disorder. Clinical phenotypic variance across geographical regions is recognised but UK BS patients' variance by age groups and gender has not been studied. This study compares the clinical features of adult and juvenile onset Behçet's Syndrome (JBS) in a UK population.

Course of Neuropsychiatric Symptoms during Flares of Systemic Lupus Erythematosus (SLE).

We present the case of a seventeen-year-old girl who presents with an interesting course of neuropsychiatric symptoms during several flares of SLE. The patient was diagnosed at the age of thirteen and has had four flares in total. The latter two flares included cutaneous and neuropsychiatric symptoms.

Diffusion-weighted imaging is a sensitive biomarker of response to biologic therapy in enthesitis-related arthritis.

Objective: The aim was to evaluate diffusion-weighted imaging (DWI) as a tool for measuring treatment response in adolescents with enthesitis-related arthropathy (ERA).

Methods: Twenty-two adolescents with ERA underwent routine MRI and DWI before and after TNF inhibitor therapy. Each patient's images were visually scored by two radiologists using the Spondyloarthritis Research Consortium of Canada system, and sacroiliac joint apparent diffusion coefficient (ADC) and normalized ADC (nADC) were measured for each patient.

Paediatric Behçet's disease: a UK tertiary centre experience.

There are currently limited data regarding paediatric Behçet's disease (BD), particularly in the UK. We describe the clinical spectrum, treatment and outcome of BD, and explore the relative sensitivities of the criteria for the diagnosis of BD in a UK paediatric cohort. Single retrospective case note review of children with a clinical diagnosis of BD presenting between 1987 and 2012.

Magnetic resonance imaging of vein wall thickness in patients with Behçet's syndrome.

Objectives: Vascular disease is a serious complication of Behçet's syndrome (BS), occurring in up to 20% of subjects. Superficial thrombophlebitis, deep vein thrombosis, and arterial aneurysm formation are the most common manifestations. Venous thrombosis is thought to result from vessel wall inflammation.

Differential diagnosis and management of Behçet syndrome.

Behçet syndrome (also known as Behçet disease) is a rare condition that is associated with considerable morbidity. Cases of Behçet syndrome have been reported worldwide, but the highest prevalence occurs in countries that border the ancient Silk Route, such as Turkey and Iran. Although oral ulceration, genital ulceration and eye disease are the classic triad of manifestations, the cardiovascular, gastrointestinal, musculoskeletal and central nervous systems can also be affected.

Heme induces heme oxygenase 1 via Nrf2: role in the homeostatic macrophage response to intraplaque hemorrhage.

Objective: Intraplaque hemorrhage (IPH) is an important progression event in advanced atherosclerosis, in large part because of the delivery of prooxidant hemoglobin in erythrocytes. We have previously defined a novel macrophage phenotype (hemorrhage-associated-mac) in human advanced plaques with IPH. These may be atheroprotective in view of raised heme oxygenase 1 (HO-1), CD163, and interleukin-10 expression and suppressed oxidative stress.

Photoprotective behaviour and sunscreen use: impact on vitamin D levels in cutaneous lupus erythematosus.

Background: Sun exposure of the skin, independent of dietary sources, may provide sufficient vitamin D in healthy individuals. A recent study of patients with cutaneous lupus erythematosus concluded that over 70% of them restrict their sun exposure.

Methods: We recruited 52 patients with biopsy-proven cutaneous lupus erythematosus to establish whether they are deficient in 25-hydroxyvitamin D [25(OH)D].

The importance of diagnosing neck pain.

Diffuse idiopathic skeletal hyperostosis is a common but poorly recognised condition that may have important and occasionally life-threatening clinical outcomes. We report the case of a 71-year-old man with giant osteophytes in his cervical spine which caused dysphagia and silent aspiration, leading to pneumonia, septicaemia, aortic wall infection and septic arthritis. Early recognition of the cause of his neck pain may have averted the subsequent clinical course.
