I am Dr Arvind Nune, a consultant rheumatologist and General Physician in the United Kingdom. I lead the early inflammatory arthritis service at my institution. My research focuses on the relationship between infection, inflammation, autoimmunity, and various rheumatic conditions. Additionally, I am interested in exploring the application of new technologies in the field of rheumatology. Incidentally, I have written an article on nanotechnology use in rheumatology. I have published over 65 peer-reviewed articles in international journals covering autoimmune rheumatic diseases, rheumatic diseases arising from COVID-19 and vaccination, and long COVID. Notably, I authored the first case study of successfully treated multisystem inflammatory syndrome in an adult following SARS-CoV-2 vaccination, which became the second-most-read medical case study in 2021. Additionally, I conducted pioneering research on the incidence and predictors of long COVID-19 in hospitalized patients 9 months after COVID-19. Another significant contribution was publishing the first case of systemic lupus erythematosus (SLE) in a young male after SARS-CoV-2 vaccination. As part of the International Multi Centre COVID-19 Vaccination in autoimmune diseases (Covid study), involving 157 collaborators from 106 countries, I investigated the long-term effects of COVID-19 and vaccination in autoimmune rheumatic diseases. Our findings were published in prestigious peer-reviewed journals including The Lancet.
