Reduced vaccine-induced germinal center outputs in patients with inflammatory bowel disease treated with anti-TNF biologics.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUNDAnti-TNF biologics are widely used to treat patients with immune-mediated inflammatory diseases. In mouse models, the complete absence of TNF impairs germinal center (GC) responses. Less is known about the impact of anti-TNF therapy on specific immune responses in humans. Widespread vaccination against SARS-CoV-2 offered an unprecedented opportunity to investigate the effects of biological therapies on responses to specific immunization. Previous work demonstrated that patients with inflammatory bowel disease (IBD) who were treated with anti-TNF biologics exhibited decreased Spike-specific antibody responses compared with patients with IBD treated with anti-IL-12/23 or healthy controls, even after 4 doses of mRNA vaccine.METHODSHere we analyzed humoral responses to SARS-CoV-2 immunization using single-cell RNA-Sequencing and flow cytometry of Spike-specific memory B cells (MBC), as well as avidity measurements of plasma antibodies from patients with IBD treated with anti-TNF or anti-IL-12/23 and from people in the healthy control group.RESULTSWe observed decreased somatic hypermutation in the B cell receptors of Spike-specific MBCs and decreased antigen-specific MBC accumulation following SARS-CoV-2 mRNA vaccination in patients with IBD treated with anti-TNF, compared with patients with IBD treated with anti-IL-12/23 or people in the healthy control group. This decreased somatic hypermutation in Spike-specific MBCs in patients treated with anti-TNF correlated with decreased and delayed antibody affinity maturation and reduced neutralization activity.CONCLUSIONThese data provide in vivo evidence that anti-TNF, but not anti-IL-12/23, therapy impairs the quantity and quality of antigen-specific GC outputs in humans.FUNDINGJuan and Stefania Speck (donation) and by Canadian Institutes of Health Research (CIHR)/COVID-Immunity Task Force (CITF) grants VR-1 172711, VS1-175545, GA2-177716, GA1-177703 and CIHR FDN 143301 &143350.
