OBJECTIVES: High-intensity laser therapy (HILT) has recently been used to control pain and symptom improvement in knee osteoarthritis. We performed a systematic review and meta-analysis of randomized controlled trials to assess the effectiveness of HILT in patients with knee osteoarthritis. METHODS: We conducted a search of articles in the MEDLINE, EMBASE, Cochrane CENTRAL, and Web of Science databases up to March 2020 for randomized controlled trials investigating HILT intervention, placebo, or active intervention as comparator groups for alleviating pain in knee osteoarthritis. Two independent reviewers evaluated the methodological quality and extracted pain and functional outcomes using a pre-specified form. A meta-analysis was performed using an inverse-variance random effect model. Heterogeneity was assessed using Higgins I2 with p-values. RESULTS: Six randomized controlled trials (RCTs) were included in this meta-analysis. For VAS pain, 334 patients from four studies showed that HILT significantly decreased pain compared to the control (MD, -1.18; 95% CI, -1.68 to -0.69). HILT significantly improved WOMAC stiffness (SMD -1.00; 95% CI -1.32, -0.68) and function (SMD, -5.36; 95% CI -7.39 to -3.34) compared to the control. CONCLUSION: The effectiveness of HILT on pain, stiffness, and function in patients with knee osteoarthritis is promising. However, due to the limited number of studies, further randomized controlled trials with large, well-designed samples are needed.

Background: Currently, there is no specific therapy for chronic pancreatitis (CP). The treatment of micronutrient antioxidant therapy for painful CP has been sporadically used for more than 30 years, however, its efficacy are still poorly understood. Objective: The purpose of this meta-analysis is to investigate the safety and efficacy of antioxidant therapy for pain relief in patients with CP. Setting: University Hospital in China Study Design: Systematic review and meta-analysis Methods: Two authors independently reviewed the search results and extracted data and disagreements were resolved by discussion. Effects were summarized using standardized mean differences (SMDs), weighted mean differences, or odds ratio (OR) according to the suitable effect model. MEDLINE, PsycINFO, Scopus, EMBASE, and the Cochrane Central Register of Controlled Trials were searched from 1980 through December 2012. Randomized controlled trials (RCTs) that studied antioxidant supplementation for pain relief in patients with CP were analyzed. Results: Nine randomized controlled trials (RCTs) involving 390 patients were included. Overall, there was no association of antioxidant therapy with pain reduction in CP patients (SMD, −0.55; 95% CI, −1.22 to 0.12; P = 0.67). However, antioxidant therapy significantly increased blood levels of antioxidants in CP patients versus the placebo group (SMD, 1.08; 95% CI, 0.74 to 1.43; P < 0.00001). Interestingly, combined antioxidant (selenium, β-carotene, vitamin C, vitamin E, methionine) therapy was found to be associated with pain relief (SMD, -0.93; 95% CI, -1.72 to -0.14; P = 0.02), while the trials in which a single antioxidant was used revealed no significant pain relief (SMD, -0.12; 95% CI, -1.23 to 0.99; P = 0.83) in CP patients. Strong evidence was obtained that the antioxidants increased adverse effects (OR, 6.09; 95% CI, 2.29 to 16.17, P < 0.01); nevertheless, none was serious. Limitations: Because of the small sample, a consolidated conclusion cannot be reached based on current RCTs. Large-sample RCTs are needed to clarify the analgesic effect of antioxidants in CP patients. Conclusions: Combined antioxidant therapy seems to be a safe and effective therapy for pain relief in CP patients. Measures of total antioxidant status may not help to monitor the efficacy of antioxidant therapy for patients with CP. Key words: Antioxidant, pain, chronic pancreatitis, meta-analysis
