Background. There are still many unmet needs in the treatment of ankylosing spondylitis (AS) among present therapies including non-steroid anti-inflammatory drugs (NSAID), disease-modifying anti-rheumatic drugs (DMARD), thalidomide and anti-tumor necrosis factor (TNF a).
Aim. To exploratorily test TCM formulas in the treatment of patients with AS.
Methods. Sixty AS patients were enrolled in this 12 weeks’ trial. Thirty-six patients with active AS, defined by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) > 3 cm in spite of 6 weeks’ NSAID treatment, were randomized to receive same NSAID alone, sulfasalazine add-on or TCM formula 小活絡丹 add-on. The other 24 patients with inactive late-stage AS, defined by BASDAI <> 2 cm, were randomized to receive龜鹿二仙膠 or左歸丸. Primary endpoint was the ASAS response criteria in intend-to-treat analysis. Secondary endpoints were BASDAI, BASFI, Bath Ankylosing Spondylitis Global Index (BAS-G), quality-of-life (QOL), ESR, HS-CRP and IgA. Cytokines level, including TNFa, IL-10 and TGFb in serum or peripheral blood mononuclear cell culture supernatant, were assayed by ELISA.
Results. Fifty-six patients completed this 12 weeks’ trial. Four patients dropped out due to poor compliance. In the active AS patients, 33.33% of NSAID arm, 41.67% of sulfasalazine arm, and 16.67% of小活絡丹 arm fit the ASAS response criteria. In the inactive AS patients, 8.3% of龜鹿二仙膠 and 25% of 左歸丸 reach the ASAS response criteria. Patients with左歸丸 got significant improvement in BASFI （p=0.018）and QOL score（p=0.024） but not BASDAI, ESR, HS-CRP, IgA. No significant differences were found in the cytokines level. No significant adverse events were found in all TCM groups.
Conclusions. In active AS patients, NSAID and sulfasalazine were superior than小活絡丹. In inactive AS patients, 左歸丸 revealed promising benefit. Further double blind placebo controlled trials are necessary.
