摘要
To evaluate the efficacy and safety of hyaluronic acid (HA) and glucosamine sulfate (GS) in alleviating symptoms and improving function of Kashin-Beck disease (KBD). A cluster-randomized, placebo-controlled trial was conducted in 150 patients with KBD. Participants were randomly allocated to receive intra-articular injection hyaluronic acid (IAHA) for 4 weeks, oral GS for 12 weeks, or oral placebo for 12 weeks. The primary outcome measures were 20 % and 50 % reductions in pain from baseline measured by the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index. Secondary outcome measures included WOMAC index parameters of pain, stiffness, and physical function. The third outcome measure was mean change in Lequence score. HA and GS were effective in reducing WOMAC pain by 20 % (differences of 43.5 % and 25.4 %) and 50 % (differences of 43.4 % and 26.9 %). Both HA and GS significantly reduced WOMAC pain, WOMAC stiffness, and WOMAC normalized score compared with placebo group (all P < 0.05). IAHA was significantly more effective than oral GS in improving WOMAC normalized score (P = 0.034), pain (P = 0.002), stiffness (P = 0.018), and P = 0.044). The results indicate that HA and GS were more effective than placebo in treating KBD and HA was more effective than GS.
