    Behçet's syndrome (BS), also known as Behçet's disease (BD), is a multisystem vasculitis characterized by oral and genital ulcers, papular and nodular skin lesions, arthritis, uveitis, venous And arterial thrombosis , aneurysm, central nervous system lesions and gastrointestinal ulcers, e.


    At present, there is no unified treatment strategy for BS, and most national guidelines recommend treatment drugs according to the involvement of different syste.

    In 2019, the.


    A subgroup analysis of a phase III randomized, placebo-controlled, double-blind study of 39 patients with BS evaluated the effect of apremilast in Japanese patients [1], and confirmed that apremilast reduced the incidence of Japanese patients with .

    Another phase III, double-blind, placebo-controlled study [2] evaluated the efficacy and safety of apremilast in the treatment of BS-related oral ulcers for up to 64 wee.


    JAK inhibitors

    As a representative disease of variant vasculitis, BS is considered to be closely related to many inflammatory pathwa.


    At present, there are few literatures on the treatment of BS with JAK inhibito.

    Another study [4] summarized the effects of tofacitinib in 13 patients with refractory BS and found that after an average follow-up of 8 months, the BS activity index was significantly improved, the inflammatory index was significantly reduced, and the amount of hormones used was significantly improv.

    However, the treatment of BS with JAK inhibitors still lacks confirmation of large sample size, especially randomized controlled tria.


    New Drugs of Biologics Emerge

    In terms of high-profile biological agents, anti-TNF drugs currently occupy the main position in the treatment of BS, but considering that some patients may be ineffective or have contraindications to TNF-α inhibitors, finding new therapeutic targets is also a current rheumatology stu.


    Therapeutic strategies targeting interleukin (IL)-17 are also considered to be potentially effective in .


    A multicenter retrospective study [5] investigated 15 patients with BS who were refractory to treatment with colchicine, disease-modifying antirheumatic drugs (DMARDs), and at least one anti-TNF-α drug, with a minimum follow-up of 6 mon.


    Notably, all patients who started on 300 mg/month achieved complete remission at 6 mont.


    Figure 4 Schematic representation of patient response to treatment during follow-up

    At present, there are no large-scale clinical studies and randomized controlled trials to confirm the efficacy of secukinumab, and from the existing studies, the current therapeutic doses are mostly 150mg and 300mg/month, which is similar to AS and psorias.


    Ustekinumab, a humanized monoclonal antibody against IL-12 and IL-23, is a multicenter, prospective, clinical trial of 30 colchicine-resistant BS patients with active oral ulce.


    Table 2 Efficacy of ustekinumab on BS-related oral ulcers

    Another study that included 14 colchicine-resistant BS patients with active oral ulcers [7] also evaluated the efficacy of ustekinumab in BS patients, and the results showed that at 12 weeks, 64% of patients achieved complete remission, 21% achieved partial remission, and 14% had no response, with a significant reduction in the median number of oral ulcers and BS disease activity score from baseline (Figure


    Figure 5 Mean number of oral ulcers in patients receiving ustekinumab (A) and

    BS Activity Score (B) 

    In general, new drugs continue to play an increasingly important role in the treatment of BS, giving patients more choices in the future, but high-quality evidence-based medicine is still lacking, and the optimal treatment population for these drugs is still uncle.

    Not clear, I hope there will be more and better research results in the future to apply precision medicine to BS and benefit more patien.

    At present, there is no unified treatment strategy for BS, and most national guidelines recommend treatment drugs according to the involvement of different syste.

    The drugs currently used for the treatment of BS include glucocorticoids, thalidomide, azathioprine, tumor necrosis factor (TNF)-α antagonists, e.

    Number of mouth ulcers and overall disease activi.

    Patients were randomly assigned to apremilast (30 mg twice daily; n=19) or placebo (n=20), and the primary endpoint was the area under the curve for the number of oral ulcers at 12 weeks (AUCWk0-12), Secondary endpoints were mouth ulcer pain, complete resolution of mouth ulcers, disease activity, and change from baseline in measures of disea.

    At week 12, patients in the apremilast group had significantly fewer canker sores (Figure 1), significantly less pain (Figure 2), and more patients achieved complete healing of canker sores (59% .

    20%), and the BS disease activity score was significantly lower than baseline (-15 vs 5), and quality of life was also improv.

    Another phase III, double-blind, placebo-controlled study [2] evaluated the efficacy and safety of apremilast in the treatment of BS-related oral ulcers for up to 64 wee.

    Patients with BS were randomly assigned to placebo or apremilast 30 mg, and all patients received treatment until week 64 and were followed up 4 weeks after treatment was discontinu.

    A total of 207 participants were included in the study, of whom 143 completed week 64 of treatme.

    The results showed that AUCWk0-12 was significantly reduced (P<0001) with apremilast compared with placebo, and the number of oral ulcers, pain, complete/partial response, disease activity and quality of life showed improvement at week 12, and continued until week 6 During the study period, no new safety concerns were observed with Apremila.

    The above data show that Apremilast is well tolerated and safe in the continuous treatment of BS-related oral ulce.

    As a representative disease of variant vasculitis, BS is considered to be closely related to many inflammatory pathwa.

    In view of the fact that the JAK-STAT (Janus kinase-signal transducers and activators of transcription) pathway is involved in multiple links and processes of the immune system in the secretion and biological effects of various cytokines , it plays an important role in the occurrence and development of vasculitis, Therefore JAK inhibitors may play a role in .

    At present, there are few literatures on the treatment of BS with JAK inhibito.

    The Zheng Wenjie team of Peking Union Medical College Hospital published a literature in 2020 [3], which introduced the efficacy and safety of tofacitinib in the treatment of BS with heart and great vessel involveme.

    A total of 5 patients who received 5-10 mg/day of tofacitinib after the combination of hormones combined with various immunosuppressants were not effective were included in the study (Table
    The average follow-up was 16 mont.

    The clinical symptoms were improved, and the inflammatory indicators were improv.

    At the same time, the amount of hormones was also reduc.

    It is believed that tofacitinib can help stabilize the condition of BS complicated with refractory large blood vessel involvement, and at the same time help reduce the amount of hormon.

    A retrospective analysis in 2019 analyzed the treatment effect of 5 BS patients using secukinumab, and found that secukinumab 150mg/month and 300mg/month improved previously refractory mucocutaneous manifestations, while 300mg/month improved mucocutaneous manifestatio.

    This study shows that coukinumab is safe and effective for refractory BS patients with mucosal and joint phenotypes, and secukinumab can be considered for phenotype-tailored treatment in clinical practi.

    At present, there are no large-scale clinical studies and randomized controlled trials to confirm the efficacy of secukinumab, and from the existing studies, the current therapeutic doses are mostly 150mg and 300mg/month, which is similar to AS and psorias.

    There is a large gap in the usage in BS, and later clinical trials will further determine the optimal therapeutic dose for BS patien.

    Ustekinumab, a humanized monoclonal antibody against IL-12 and IL-23, is a multicenter, prospective, clinical trial of 30 colchicine-resistant BS patients with active oral ulce.

    Enrolled patients received 90 mg of ustekinumab subcutaneously at weeks 0 and 4, and then every 12 wee.

    The number of oral ulcers in each patient was assessed longitudinally, and the median [interquartile range (IQR)] of oral ulcers was calculat.

    The primary efficacy endpoint was the proportion of patients achieving complete remission (defined as the absence of oral ulcers) at week 1 The results showed that after 12 weeks of ustekinumab treatment, the median number of oral ulcers per patient was significantly lower than baseline (P<0001), of which 18 (60%) patients achieved complete remission and 9 (30%) patients achieved complete remissi.

    Patients achieved partial responses and 3 (10%) patients had no responses (Table
