Objectives Hydroxychloroquine HCQ has been used for decades to treat patients with rheumatic diseases, for example, systemic lupus erythematosus SLE, rheumatoid arthritis or the antiphospholipid syndrome APS. We hypothesise that HCQ might target endosomal NADPH oxidase NOX, which is involved in the signal transduction of cytokines as well as antiphospholipid antibodies aPL. Methods.

Dec 17, 2018 Although obvious reasons exist to believe hydroxychloroquine may be useful to treat APS, its use in APS patients remains controversial. Those who argue for its use note that among hydroxychloroquine’s many mechanisms of action is its ability to inhibit aB2GPI binding to phospholipid bilayers.
