32514854 A case with rheumatoid arthritis and insufficient compensation under disease-modifying combined long-term therapy with methotrexate and leflunomide is reported.
32562070 Recurrences of COVID-19 were observed in a patient with long-term usage of hydroxychloroquine, leflunomide, and glucocorticoids due to her 30-year history of rheumatoid arthritis (RA).
32696396 In the present study, we evaluated Leflunomide, an approved DHODH inhibitor widely used as a modest immune regulator to treat autoimmune diseases, in treating COVID-19 disease with a small-scale of patients. […] Five of the patients were treated with Leflunomide, and another five were treated as blank controls without a placebo. […] The patients given Leflunomide had a shorter viral shedding time (median of 5 days) than the controls (median of 11 days, P = 0.046). […] The patients given Leflunomide also showed a significant reduction in C-reactive protein levels, indicating that immunopathological inflammation was well controlled. […] No obvious adverse effects were observed in Leflunomide-treated patients, and they all discharged from the hospital faster than controls. […] This preliminary study on a small-scale compassionate use of Leflunomide provides clues for further understanding of Leflunomide as a potential antiviral drug against COVID-19.
32743705 One patient with seronegative polyarticular JIA, previously prescribed methotrexate and receiving leflunomide during pandemic was identified to be diagnosed with COVID-19.
32754890 This work demonstrates that both S312/S416 and old drugs (Leflunomide/Teriflunomide) with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide, no matter such viruses are mutated or not.
32829915 A77 1726 is the active metabolite of leflunomide, a clinically approved anti-rheumatoid arthritis (RA) drug. […] Leflunomide has potential therapeutic value for the control of PEDV and other coronavirus infections.
32837197 Treatment with sulfasalazine, methotrexate, leflunomide, immunosuppressants and biological agents other than interluekin-6 receptor inhibitors and JAK inhibitors should be stopped or withheld.
32892311 • Patients doing well on a stable dose of steroid and/or Disease-Modifying Antirheumatic Drugs (DMARDs) should be allowed to continue the same unless they get infected in which case, temporary stoppage of methotrexate and leflunomide may be considered.
32931985 One large cohort study demonstrated an association with leflunomide use and increased risk of acute viral respiratory events compared to non-use.
32952617 In fact, there are other immunosuppressants known with antiviral activities, including cyclosporine A, hydroxyurea, minocycline, mycophenolic acid, mycophenolate mofetil, leflunomide, tofacitinib, and thalidomide.
32955081 To evaluate the efficacy and safety of leflunomide, an approved dihydroorotate dehydrogenase inhibitor, to treat COVID-19 patients with prolonged post-symptomatic viral shedding. […] Patients were randomly assigned to receive either leflunomide (50 mg, q12h, three consecutive times, orally; then 20 mg, once daily for 8 days), in addition to nebulized interferon alpha 2a (IFN α-2a, 3 million IU each time, twice daily for 10 days), or nebulized IFN α-2a alone for 10 days. […] A total of 50 COVID-19 patients with prolonged PCR positivity were randomized into 2 groups; 26 were assigned to the leflunomide group, and 24 were assigned to the interferon alone group. […] Treatment with leflunomide was not associated with a difference from the interferon alone group in the duration of viral shedding (hazard ratio for negative RT-PCR, 0.70; 95% confidence interval, 0.391-1.256; P=0.186). […] In addition, the patients given leflunomide did not have a substantially shorter length of hospital stay than patients treated with interferon alone, with median (IQRs) durations of 29.0 (19.3-47.3) days and 33.0 (29.3-42.8) days, respectively, P=0.170. […] Two leflunomide recipients were unable to complete the full 10-day course of administration due to adverse events. […] In COVID-19 patients with prolonged PCR positivity, no benefit in terms of the duration of viral shedding was observed with the combined treatment of leflunomide and IFN α-2a beyond IFN α-2a alone.
33128696 Besides, taking DMARDs, such as leflunomide, might possess a protective effect against severe COVID-19, probably as a result of preventing cytokine storm.
33571819 Leflunomide (LF) represents the prototype member of dihydroorotate dehydrogenase (DHODH) enzyme inhibitors.
33589438 Randomised controlled trials (RCTs) were available for the following drugs: hydroxychloroquine (n=12), glucocorticoids (n=6), tocilizumab (n=4), convalescent plasma (n=4), interferon beta (n=2), intravenous immunoglobulins (IVIg) (n=2) and n=1 each for anakinra, baricitinib, colchicine, leflunomide, ruxolitinib, interferon kappa and vilobelimab.
