In this MTX+PNL vs TCZ+PNL in GCA study, we saw 5 pts on MTX+PNL get PJP, very surprising. @EBRheum asked what I knew/hoped he’d ask: why did this happen? PJP is v rare in GCA (https://t.co/oPN0dpvG8Q) & with MTX in other diseases. Worth interrogation! #ACR25 ABST0891 @RheumNow https://t.co/rsbScryIFR
