Determinants and progression of stigma in amyotrophic lateral sclerosis/motor neuron disease.

: Stigma in amyotrophic lateral sclerosis/motor neurone disease (ALS/MND) may be felt or enacted; felt stigma covers feeling devalued by the illness, whereas enacted stigma refers to being treated differently because of it. Stigma in ALS/MND has been shown to increase social withdrawal, worsen quality of life, and reduce use of assistive devices, so we explored prevalence and factors influencing stigma. : Participants in the Trajectories of Outcome in Neurological Conditions-ALS study completed scales measuring stigma, fatigue, spasticity, functioning, mood, worry, self-esteem, and perceived health, as well as demographic information and symptoms like head drop or emotional lability.

Antiphospholipid antibody levels in early systemic lupus erythematosus: are they associated with subsequent mortality and vascular events?

Objectives: aPL are present in between 20 and 30% of patients with SLE. They can cause vascular events (VE) or pregnancy morbidity. aCL and anti-beta-2-glycoprotein I (anti-β2GPI) are measured in clinical practice.

Resolving TYK2 locus genotype-to-phenotype differences in autoimmunity.

Thousands of genetic variants have been identified, which contribute to the development of complex diseases, but determining how to elucidate their biological consequences for translation into clinical benefit is challenging. Conflicting evidence regarding the functional impact of genetic variants in the tyrosine kinase 2 (TYK2) gene, which is differentially associated with common autoimmune diseases, currently obscures the potential of TYK2 as a therapeutic target. We aimed to resolve this conflict by performing genetic meta-analysis across disorders; subsequent molecular, cellular, in vivo, and structural functional follow-up; and epidemiological studies.

IgG anti-apolipoprotein A-1 antibodies in patients with systemic lupus erythematosus are associated with disease activity and corticosteroid therapy: an observational study.

Introduction: IgG anti-apolipoprotein A-1 (IgG anti-apoA-1) antibodies are present in patients with systemic lupus erythematosus (SLE) and may link inflammatory disease activity and the increased risk of developing atherosclerosis and cardiovascular disease (CVD) in these patients. We carried out a rigorous analysis of the associations between IgG anti-apoA-1 levels and disease activity, drug therapy, serology, damage, mortality and CVD events in a large British SLE cohort.

Methods: Serum IgG anti-apoA-1 levels were measured in 100 healthy controls to define a cut-off for positivity.

CD8⁺ MAIT cells infiltrate into the CNS and alterations in their blood frequencies correlate with IL-18 serum levels in multiple sclerosis.

Recent findings indicate a pathogenic involvement of IL-17-producing CD8(+) T cells in multiple sclerosis (MS). IL-17 production has been attributed to a subset of CD8(+) T cells that belong to the mucosal-associated invariant T (MAIT) cell population. Here, we report a reduction of CD8(+) MAIT cells in the blood of MS patients compared with healthy individuals, which significantly correlated with IL-18 serum levels in MS patients.

TNF receptor 1 genetic risk mirrors outcome of anti-TNF therapy in multiple sclerosis.

Although there has been much success in identifying genetic variants associated with common diseases using genome-wide association studies (GWAS), it has been difficult to demonstrate which variants are causal and what role they have in disease. Moreover, the modest contribution that these variants make to disease risk has raised questions regarding their medical relevance. Here we have investigated a single nucleotide polymorphism (SNP) in the TNFRSF1A gene, that encodes tumour necrosis factor receptor 1 (TNFR1), which was discovered through GWAS to be associated with multiple sclerosis (MS), but not with other autoimmune conditions such as rheumatoid arthritis, psoriasis and Crohn’s disease.

Subarachnoid haemorrhage in undiagnosed secondary hypertension: back to basics.

Aortic coarctation (AC) is a significant cause of secondary hypertension and is diagnosed in childhood in the vast majority of patients. Mild or moderate coarctation may exist undetected into adult life, when it usually presents due to its sequelae. The authors present the case of a 20-year-old woman, previously extensively investigated for severe hypertension, who was admitted following sever, sudden-onset headache.
