Seroprevalence of Borrelia burgdorferi sensu lato antibodies in English adult blood donors: A nationwide cross-sectional study, 2021-2022.

Background: Estimates of Lyme disease incidence in England are based on reporting of cases with a laboratory-confirmed diagnosis only, underestimating total cases. In 2017 - 2018, two independent reviews commissioned by the UK Government highlighted the lack of official data on Lyme disease prevalence and incidence as a critical knowledge gap.

Aim: To estimate the prevalence of IgG antibodies in the English adult population specific for Borrelia burgdorferi sensu lato (Bbsl), the causative agent of Lyme disease.

Research and product development for Crimean-Congo haemorrhagic fever: priorities for 2024-30.

Crimean-Congo haemorrhagic fever (CCHF) is a widely distributed and potentially fatal tick-borne viral disease with no licensed specific treatments or vaccines. In 2019, WHO published an advanced draft of a research and development roadmap for CCHF that prioritised the development and deployment of the medical countermeasures most needed by CCHF-affected countries. This Personal View presents updated CCHF research and development priorities and is the product of broad consultation with a working group of 20 leading experts in 2023-24.

Lyme disease in UK primary care: a knowledge, attitude and practice survey.

Background: Lyme disease (LD) cases in the UK most commonly present within the primary care setting. Despite an upward trend of incidence, little is known regarding general practitioner (GP) experience with diagnosis and treatment.

Aim: This study aims to describe baseline primary care clinician Knowledge, Attitude and Practice (KAP) in Scotland and England.

Effect of a 2-week interruption in methotrexate treatment on COVID-19 vaccine response in people with immune-mediated inflammatory diseases (VROOM study): a randomised, open label, superiority trial.

Background: Methotrexate is the first-line treatment for immune-mediated inflammatory diseases and reduces vaccine-induced immunity. We evaluated if a 2-week interruption of methotrexate treatment immediately after COVID-19 booster vaccination improved antibody response against the S1 receptor binding domain (S1-RBD) of the SARS-CoV-2 spike protein and live SARS-CoV-2 neutralisation compared with uninterrupted treatment in patients with immune-mediated inflammatory diseases.

Method: We did a multicentre, open-label, parallel-group, randomised, superiority trial in secondary-care rheumatology and dermatology clinics in 26 hospitals in the UK.

The importance of using WHO International Standards to harmonise SARS-CoV-2 serological assays.

The COVID-19 pandemic led to the rapid development of tests to diagnose SARS-CoV-2 infection and ascertain the prevalence of infection, along with the formulation of various treatments and vaccines. Globally, over 220 anti-SARS-CoV-2 serological assays have been developed for laboratory use, and many of these assays are currently used to assess immune responses against SARS-CoV-2. However, because these assays were independently developed by different manufacturers with different target antigens, immunoglobulin detection, technologies, and data reporting approaches, the results are not directly comparable, making it challenging to draw conclusions regarding immune responses at the population level.
