TL;DR: The virological and immunological responses following plasma treatment helps to understand which COVID-19 patients may benefit from this therapy and should be the focus of future studies, and substantiates that convalescent plasma should be studied as early as possible in the disease course or at least preceding the start of an autologous humoral response.

TL;DR: IgG4-RD in children is a generally unknown disease among pediatricians, but several pediatric cases have been described and Prednisone is the first choice of treatment leading to disease remission in the majority of the cases.

TL;DR: Low absolute neutralization levels for BA.4 and BA.5, particularly in the unvaccinated group, are unlikely to protect well against symptomatic infection, and may indicate that the SARS-CoV-2 Omicron sub-lineage has potential to result in a new infection wave.

TL;DR: The authors describe a case of a 61-year-old woman, initially diagnosed with idiopathic orbital inflammation refractory to multiple immunosuppressive agents, who was effectively treated with infliximab, the second case of IgG4-RD treated with a TNF-blocker documented in literature and the first description to demonstrate its superiority over steroid sparing agents.
