    In fact, there are other immunosuppressants known with antiviral activities, including cyclosporine A, hydroxyurea, minocycline, mycophenolic acid, mycophenolate mofetil, leflunomide, tofacitinib, and thalidomide.The inherent antiviral activity could be a treatment choice for patients with coexisting rheumatological disorders and infections.Clinical evidence, their possible mode of actions and spectrum of antiviral activities are included in this review article.However, some diseasemodifying antirheumatic drugs with inherent antiviral activity would be a reasonable choice in the situation of concomitant viral infections and flare up of autoimmune diseases.However, some immunosuppressants or diseasemodifying antirheumatic drugs show antiviral activity and may be safely used or even beneficial in patients with selected concomitant viral infections.Moreover, the concomitant use of immunosuppressants and antiviral agents was proved to be more effective than antiviral agent monotherapy in some reports.The antiviral property of immunosuppressants may act through buy NMDA inhibition of necessary molecules for viral replication in the hosts, or amelioration of inflammatory symptoms.Also, control of inflammation may decrease the susceptibility or enhance host ability to defend against viral infection.Antiviral agents with immunosuppressive activity such as ribavirin are beyond the scope of this review.Reference lists of pertinent articles were hand searched for additional studies of interest.It is transmitted efficiently by droplets and is contagious between humans.In addition, the application for viral infections in offlabel use has recently been investigated vigorously.The antiviral activity is through blocking the viruscell fusion via increasing endosomal pH and hindering the glycosylation of cellular receptors and high halfcytotoxic concentration for COVID.Then, four completed clinical studies demonstrated favorable outcomes in clinical and radiologic amelioration, while another two randomized controlled trials illustrated no statistically significant change compared with control arms.Article selection flowchart.In one controlled openlabel study, patients were given either baricitinib mgday plus lopinavirritonavir or antiretroviral plus hydroxychloroquine for weeks.Significant improvement of symptoms and laboratory results, no intensive care unit transfer was shown among the baricitinibtreated individuals.In addition to antiviral property, baricitinib has been suggested as an approach for a cytokine storm syndrome, which features hypercytokinemia and multiorgan failure.Baricitinib inhibits cytokines including IL, IL, IL, interferon gamma, and may bring the benefit of immune reconstruction which could be used in rapidly progressive diseases.Therefore, some experts suggested baricitinibs use in the situation of hyperinflammation and cytokine syndrome, rather than in those with mild diseases.CsA inhibits lymphocyte function, mainly T cells, by forming a complex with cyclophilin.Patients with MDA plus CADM have higher risks of developing rapidly progressive interstitial lung diseases and respiratory failure, while this could be reversed by calcineurin inhibitors.IMPDH inhibition especially influences T and B lymphocytes because they use almost a de novo pathway to synthesize. Although they were associated with higher risk of opportunistic infections including herpes zoster, cytomegalovirus nephropathy, literature also revealed its possible benefit for HIV and influenza virus.DHODH is another essential enzyme for pyrimidine synthesis, and MMF might control viral infection by depleting the intracellular pyrimidine pools.It exerts antiinflammatory effect through cereblon E ubiquitin ligase as the primary target and thus inhibits chemotaxis of leukocytes, monocytes as well as the production of tumor necrosis factor alpha, IL, and IL.
