The clinical effectiveness of #clarithromycin versus endoscopic sinus surgery for adults with chronic #rhinosinusitis with and without nasal #polyps (MACRO): a pragmatic, multicentre, three-arm, randomised, placebo-controlled phase 4 trial

aledopress

SummaryBackgroundA paucity of evidence regarding use of endoscopic sinus surgery and antibiotics in managing chronic rhinosinusitis has contributed to a five-times variation in endoscopic sinus surgery rates, as well as variation in the use of antibiotics. The main aim of the present trial was to compare the clinical effectiveness of endoscopic sinus surgery or 3… Continue reading The clinical effectiveness of #clarithromycin versus endoscopic sinus surgery for adults with chronic #rhinosinusitis with and without nasal #polyps (MACRO): a pragmatic, multicentre, three-arm, randomised, placebo-controlled phase 4 trial

Intranasal priming induces local lung-resident B cell populations that secrete protective mucosal antiviral IgA

aledopress

Flu defense via lung-resident IgA+ memory B cellsSecretory IgA antibody is known to be a key effector molecule in establishing effective antiviral immunity in the lungs, but the specific cell types producing this mucosal IgA and their physical locations are unclear. Oh et al. analyzed pulmonary IgA-secreting cells in mice after prior influenza infection or… Continue reading Intranasal priming induces local lung-resident B cell populations that secrete protective mucosal antiviral IgA
