OBJECTIVE: To investigate the structural and symptomatic efficacy and safety of glucosamine in knee osteoarthritis (OA). DATA SOURCES: Clinical trials of glucosamine were identified through electronic searches (MEDLINE, EMBASE, BIOSIS, EMB review, the Cochrane Library) using the key words glucosamine, osteoarthritis, degenerative joint disease, degenerative arthritis, osteoarthrosis, gonarthrosis, knee, disease progression, and clinical trial. The bibliographic databases were searched from their respective inception dates to August 2004. We also hand-searched reference lists of relevant articles. STUDY SELECTION AND DATA EXTRACTION: Studies were included if they were double-blind, randomized, controlled trials that evaluated oral glucosamine long-term treatment in knee OA; lasting at least one year; and reporting as outcome measures the symptom severity and disease progression as assessed by joint space narrowing. Two authors interpreted data independently. Disagreements were resolved through discussion. DATA SYNTHESIS: Glucosamine sulfate was more effective than placebo in delaying structural progression in knee OA. The risk of disease progression was reduced by 54% (pooled RR 0.46; 95% CI 0.28 to 0.73; p = 0.0011). The number-needed-to-treat was 9 (95% CI 6 to 20). The pooled effect sizes for pain reduction and improvement in physical function were 0.41 (95% CI 0.21 to 0.60; p < 0.0001) and 0.46 (95% CI 0.27 to 0.66; p < 0.0001), respectively, in favor of glucosamine sulfate. Glucosamine sulfate caused no more adverse effects than placebo. CONCLUSIONS: The available evidence suggests that glucosamine sulfate may be effective and safe in delaying the progression and improving the symptoms of knee OA. Due to the sparse data on structural efficacy and safety, further studies are warranted.

Background: Depression is a major nonmotor symptom of Parkinson’s disease (PD). However, few treatments exist for PD depression. Monoamine oxidase-B inhibitors (MAOB-Is) provide symptomatic relief for the motor symptoms of PD and exert antidepressive effects. The present meta-analysis of randomized controlled trials (RCTs) investigated the effects of MAOB-Is on depressive symptoms in patients with PD. Methods: Articles on PD-management-related RCTs using one of three MAOB-Is approved by the US Food and Drug Administration, that is, selegiline, rasagiline, and safinamide, were identified. The primary outcomes were the benefits of MAOB-Is for depressive symptoms. Subgroup analysis included the effects of MAOB-Is on patients in the early versus middle-to-late stages of PD and the effect of short-term versus long-term treatment. Results: Overall, six studies were included, four of which were conducted on patients with early stage PD. Overall, MAOB-Is significantly reduced the severity of depressive symptoms [standardized mean difference (SMD): −0.14, 95% confidence interval (CI): −0.21 to −0.06, p < 0.001]. Subgroup analysis indicated that the positive effect of MAOB-Is was significant in patients with early stage PD (SMD: −0.20, 95% CI: −0.31 to −0.09, p < 0.001), but not in those with middle-to-late-stage PD (SMD: −0.07, 95% CI: −0.17 to 0.03, p = 0.18). The antidepressive effect was significant for short-term treatment, that is, 90–120 days (SMD: −0.23, 95% CI: −0.35 to −0.10, p < 0.001), but not long-term treatment, that is, 24 weeks to 18 months (SMD: −0.08, 95% CI: −0.18 to 0.01, p = 0.09). Conclusion: In addition to the treatment of PD motor symptoms, MAOB-Is may help reduce the severity of depressive symptoms in PD, especially in patients with early stage PD. Considering the tolerability and simultaneous benefits of MAOB-Is, further RCTs are warranted to confirm their therapeutic effects in moderate-to-severe PD depression.

Background:Knee osteoarthritis (OA) is a frequent degenerative disease representing an important health and economic burden. Symptomatic medical treatments available include intra-articular (IA) injections of corticosteroids (GC) but their efficacy is debated. In addition, safety signals regarding cartilage damage with IA GC have been highlighted in a few studies.Objectives:To perform a meta-analysis of studies assessing IA GC efficacy and safety in knee OA.Methods:A systematic literature review and a meta-analysis of randomized controlled trials (RCTs) assessing the effect of GC IA injections versus other interventions (IA Hyaluronic Acid, IA placebo, IA NSAID, oral NSAID or physiotherapy) in knee OA was performed. The effect of the interventions on pain and function were extracted from the single studies and pooled and are presented as short term (<6weeks), medium term (6-24 weeks) and long term (>24 weeks) follow-up period. Standardized mean differences (SMD) are reported.Results:Of 520 studies screened, 23 were included in the SLR and 14 subsequently included in the MA. While IA GC showed a superior effect compared to control on both pain (SMD -0.61 (95% CI -1,25, 0.03)) and function (SMD -1.02 (95% CI -2.14, 0.10)) in short term follow-up; long term follow-up analysis favored controls (IA HA, IA NSAID, physiotherapy) for both pain (SMD 0.68 (95% CI -0.11, 1.47)) and function (SMD 0.88 (95% CI -0.36, 2.12) outcomes (Figure 1). No difference was found between interventions in the medium term. Safety data were reported in 18/23 studies (n= 1936/2314 patients); and side effects were reported as follows: arthralgia (69 IA GC patients, 146 IA HA patients, and 20 saline patients); site injection pain (7 in the IA GC group, 2 in the IA saline group, 14 in the IA HA group); 16 post injection knee swelling without signs of septic arthritis in the IA GC group and 24 in the IA HA group. In one study assessing cartilage effects of GCs, the rate of cartilage loss was greater in the GC group with a reduction of cartilage thickness at 2 year compared to placebo group. No difference was observed in the progression of cartilage denudation or bone marrow lesion. On the contrary, another study showed no effect of injections on the cartilage structure.Conclusion:We demonstrate in this work that IA GC injections reduce pain and improve function in the early phase (≤6 weeks) of treatment. In the long term (≥24 weeks), other intervention such as IA HA injections or physiotherapy seem to be more efficient, but this effect was largely driven by single studies with large effect sizes and the comparators were heterogeneous.Figure 1.Knee pain outcome at short term (≤6weeks) (A), medium term (>6 & <24 weeks) (B), and long term (≥24 weeks) (C) follow up.Disclosure of Interests:None declared.

Abstract Background The clinical utility of radiofrequency (RF) in patients with knee osteoarthritis (OA) remains unclear. We conducted a meta-analysis to systematically evaluate the efficacy and safety of RF treatment in patients with knee OA. Methods Searches of the PubMed, Web of Science, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and Wanfang Data databases were performed through August 30, 2021. The major outcomes from published randomized controlled trials (RCTs) involving patients with knee OA were compared between RF and control groups, including Visual Analogue Scale (VAS) or Numerical Rating Scale (NRS) scores, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford Knee Score (OKS), Global Perceived Effect (GPE) scale, and adverse effects at available follow-up times. Results Fifteen RCTs involving 1009 patients were included in this meta-analysis, and the results demonstrated that RF treatment correlated with improvements in pain relief (VAS/NRS score, all P < 0.001) and knee function (WOMAC, all P < 0.001) at 1–2, 4, 12, and 24 weeks after treatment as well as patients’ degree of satisfaction with treatment effectiveness (GPE scale, 12 weeks, P < 0.001). OKSs did not differ significantly between the two groups. Moreover, treatment with RF did not significantly increase adverse effects. Subgroup analysis of knee pain indicated that the efficacy of RF treatment targeting the genicular nerve was significantly better than intra-articular RF at 12 weeks after treatment (P = 0.03). Conclusions This meta-analysis showed that RF is an efficacious and safe treatment for relieving knee pain and improving knee function in patients with knee OA.

Objective To evaluate the efficacy and safety of radiofrequency ablation for the treatment of knee osteoarthritis. Methods A literature review was conducted using the PubMed, Cochrane Review, Embase, and Google Scholar databases. Two reviewers independently assessed the eligibility of all retrieved studies. The research was reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to ensure the reliability and verity of the results. The statistical analysis was performed using STATA version 13.0. Results Nine randomized controlled trials were collected for the data extraction and meta-analysis. Significant differences in the pain score at 4, 12, and 24 weeks were found between patients treated with radiofrequency ablation and those treated with placebo. Furthermore, the use of radiofrequency ablation was associated with an improved outcome of the Western Ontario and McMaster Universities Arthritis Index at 4, 12, and 24 weeks. No serious adverse events were observed in any patients who underwent radiofrequency ablation. Conclusion Radiofrequency ablation is efficacious and safe for reducing pain and improving knee function in patients with knee osteoarthritis, without increasing the risk of adverse effects.
