Intravenous pulse methylprednisolone for induction of remission in severe ANCA associated Vasculitis: a multi-center retrospective cohort study.

Background: Intravenous pulse methylprednisolone (MP) is commonly included in the management of severe ANCA associated vasculitis (AAV) despite limited evidence of benefit. We aimed to evaluate outcomes in patients who had, or had not received MP, along with standard therapy for remission induction in severe AAV.

Methods: We retrospectively studied 114 consecutive patients from five centres in Europe and the United States with a new diagnosis of severe AAV (creatinine > 500 μmol/L or dialysis dependency) and that received standard therapy (plasma exchange, cyclophosphamide and high-dose oral corticosteroids) for remission induction with or without pulse MP between 2000 and 2013.

Treatment of fatigue with physical activity and behavioural change support in vasculitis: study protocol for an open-label randomised controlled feasibility study.

Introduction: Fatigue is a major cause of morbidity, limiting quality of life, in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). The aetiology of fatigue is multifactorial; biological and psychosocial mediators, such as sleep deprivation, pain and anxiety and depression, are important and may be improved by increasing physical activity. Current self-management advice is based on expert opinion and is poorly adhered to.

Subclinical Reactivation of Cytomegalovirus Drives CD4+CD28null T-Cell Expansion and Impaired Immune Response to Pneumococcal Vaccination in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis.

Background: Infection is the leading cause of death in antineutrophil cytoplasmic antibody-associated vasculitis (AAV). Expansion of CD4+CD28null T cells is associated with increased risk of infection and mortality, but is only present in cytomegalovirus (CMV)-seropositive individuals. We hypothesized that subclinical CMV reactivation drives CD4+CD28null T-cell expansion, that this is associated with impaired immune response to heterologous antigens, and that antiviral therapy may ameliorate this.

How does the outcome of research training fellowships funded via the NHS compare with that from competitively funded fellowships from the MRC and other charities: a cross-sectional retrospective survey of trainees undertaking research training in the West Midlands.

Objectives: This study aimed to investigate the impact of research training funded via the National Health Service (NHS) on medical trainees compared with traditional clinical research training fellowships (CRTFs).

Design, Setting And Participants: Online survey of 221 clinical trainees who had completed a period of research during their clinical training between 2009 and 2015 in the West Midlands.

Main Outcome Measures: Research outcomes.

Negative anti-neutrophil cytoplasm antibody at switch to maintenance therapy is associated with a reduced risk of relapse.

Background: Relapse of disease is frequent in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV). It is unclear whether persistent ANCA when starting maintenance therapy increases the risk of relapse. We examined the association between ANCA status and relapse in two randomised controlled trials.

Valaciclovir to prevent Cytomegalovirus mediated adverse modulation of the immune system in ANCA-associated vasculitis (CANVAS): study protocol for a randomised controlled trial.

Background: The ANCA-associated vasculitides (AAV) are systemic autoimmune inflammatory disorders characterised by necrotising inflammation affecting small to medium-sized blood vessels. Despite improvements in survival, infection and cardiovascular disease remain leading causes of morbidity and mortality. Considerable evidence suggests that CD4 + CD28null T-cell expansions, predominantly seen in Cytomegalovirus (CMV) seropositive individuals, are associated with systemic dysregulation of immune function leading to a heightened risk of infection and cardiovascular disease.

Association of Low B Cell Count and IgG Levels With Infection, and Poor Vaccine Response With All-Cause Mortality in an Immunosuppressed Vasculitis Population.

Objective: Patients with systemic vasculitis (SV) have an increased risk of all-cause mortality, often due to infection, compared to the healthy population. We investigated whether humoral response to vaccination and biomarkers of immune dysfunction were associated with infection and death.

Methods: Patients with SV in remission were vaccinated with pneumococcal 7-valent conjugate, Haemophilus influenzae type b, and meningococcal group C conjugate vaccine and meningococcal polysaccharide groups A, C, Y, and W135 vaccines.

Anti-neutrophil cytoplasm-associated glomerulonephritis.

Wegener's granulomatosis, microscopic polyangiitis, and renal limited vasculitis are associated with circulating anti-neutrophil cytoplasm antibodies and are an important cause of rapidly progressive glomerulonephritis. This review gives an account of recent advances in the understanding of the pathogenesis underlying these conditions and how these may lead to future treatments. Consideration is given to recent clinical trials in the management of anti-neutrophil cytoplasm antibodies (ANCA)-associated vasculitides.
