The question of whether psoriasis is a state or pre-clinical psoriatic arthritis has been addressed by several studies; with one suggesting that biologic use in psoriasis may aver the future development of psoratic arthritis (PsA).

The Annals of Rheumatic Disease has published the results of a head-to-head trial showing that the Janus kinase-1 (JAK1) preferential inhibitor filgotinib was superior to a tumour necrosis factor-α inhibitor (adalimumab) in active rheumatoid arthritis (RA) on methotrexate (MTX).

The NEJM has published results of a real-world efficacty trial showing that COVID infected children with the multisystem inflammatory syndrome in children (MIS-C) respond better to initial IVIG plus glucocorticoids (than IVIG alone) which was associated with less subsequent cardiovascular co

NEJM has published the results of an observational trial wherein tofacitinib given to patients hospitalized with Covid-19 pneumonia, was shown to significantly lower risk of death or respiratory failure.

The potential transition from psoriasis (PsO) to psoriatic arthritis (PsA) has not been a strong focus for several years but is gaining momentum.
