COVID-19 vaccination is critical in frequently immunocompromised patients with rheumatoid arthritis (RA). However, there is a question about the risk of RA flares following vaccination. Our study intended to find out about cases of new RA or flare-ups in people who already had RA that were reported in French and international pharmacovigilance databases after COVID-19 vaccination. We performed a "case-noncase" method in the international pharmacovigilance database VigiBase to identify the risk of RA following COVID-19 vaccination compared with other nonlive vaccines. Using the French Pharmacovigilance Database (FPVD), a descriptive analysis was carried out for RA cases after COVID-19 immunization and a multivariate logistic regression analysis was conducted to compare variables in the new-onset vs. flare-up groups. In 2021, 2,387 cases of RA were reported from 2,817,902 adverse drug reactions associated with COVID-19 vaccines recorded in VigiBase. The reporting odds ratio of RA onset with COVID-19 vaccines compared with the other nonlive vaccines was 0.66 (P < 0.0001). The FPVD reported 161 cases of RA with COVID-19 vaccines, including 77 new-onset RA and 84 cases of RA flare-up. In 88 cases (84.7%), RA occurred after the first dose. The mean time between vaccination and disease onset was 14 ± 21 days, and the delay was significantly shorter in the flare-up group. We do not show a higher risk of RA after COVID-19 vaccination compared with other nonlive vaccines in adults. De novo RA was more likely to happen quickly, be more severe, and have a worse outcome than flares in patients with RA.

Since the precursor frequency of naive T cells is extremely low, investigating the early steps of antigen-specific T cell activation is challenging. To overcome this detection problem, adoptive transfer of a cohort of T cells purified from T cell receptor (TCR) transgenic donors has been extensively used but is not readily available for emerging pathogens. Constructing TCR transgenic mice from T cell hybridomas is a labor-intensive and sometimes erratic process, since the best clones are selected based on antigen-induced CD69 upregulation or IL-2 production in vitro, and TCR chains are polymerase chain reaction (PCR)-cloned into expression vectors.

This study quantifies the impact of COVID-19 vaccination on hospitalization for COVID-19 infection in a South African private health insurance population. This retrospective cohort study is based on the analysis of demographic and claims records for 550,332 individuals belonging to two health insurance funds between 1 March 2020 and 31 December 2022. A Cox Proportional Hazards model was used to estimate the impact of vaccination (non-vaccinated, partly vaccinated, fully vaccinated) on COVID-19 hospitalization risk; and zero-inflated negative binomial models were used to estimate the impact of vaccination on hospital utilization and hospital expenditure for COVID-19 infection, with adjustments for age, sex, comorbidities and province of residence.

Associated factors related to production of autoantibodies and dermo-epidermal separation in bullous pemphigoid.

Bullous pemphigoid (BP) is a debilitating autoimmune skin blistering disease, characterized by the deposition of specific autoantibodies at the dermal-epidermal junction. This leads to an inflammatory cascade involving the activation of complement proteins, mast cell degranulation, immune cell recruitment, and the release of proteases by granulocytes. While several cytokines and signaling pathways have been implicated in the pathogenesis of BP, the precise mechanism behind autoantibody production remains unclear.

The global epidemic of bovine coronavirus (BCoV) has caused enormous economic losses. The characterisation and genetic composition of endemic strains in Southwest China remain elusive. This study aimed to fill this gap by isolating three BCoV strains from this region and sequencing their whole genomes.
