    Arthritis Rheumatol 2017 Nov 16. Epub 2017 Nov 16.
    Division of Rheumatology, Department of Medicine of the Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.
    Forty years have passed since it was first recognized that patients with autoimmune rheumatic disease have an increased risk of fatal and non-fatal cardiovascular (CV) events (1) Although initial reports focused on rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), similar findings were verified subsequently in patients with psoriasis (Ps) and/or psoriatic arthritis (PsA) and spondyloarthritis. An early feature of the atherosclerotic lesion is infiltration with inflammatory cells, particularly monocytes/macrophages, and the presence of these cells in mature plaque elevates the risk of plaque rupture and thrombosis (2). In the general population, modest elevations of circulating inflammatory proteins, including C-reactive protein (CRP), interleukin-6 (IL-6) and soluble endothelial adhesion proteins, are associated with an increased risk of acute CV events (3).

    Psoralen compounds such as methoxsalen are photosensitizer agents used in conjunction with ultraviolet A (UVA) radiation exposure as photochemotherapy (Psoralens and ultraviolet-A therapy [PUVA therapy]) for certain epidermal skin disorders such as psoriasis and vitiligo. Methoxsalen has been shown to be associated with premature cataract formation by forming adducts with lens proteins following oral administration and subsequent UVA exposure. Hence, the use of UV-filtering glasses is recommended during PUVA therapy sessions. Read More

    There remains an unmet dermatological need for innovative topical agents that achieve better longterm outcomes with fewer side effects. Modulation of the expression and activity of microRNA (miRNAs) represents an emerging translational framework for the development of such innovative therapies because changes in the expression of one miRNA can have wide-ranging effects on diverse cellular processes associated with disease. In this short review, the roles of miRNA in epidermal development, psoriasis, cutaneous squamous cell carcinoma and re-epithelisation are highlighted. Read More
