Efficacy of autologous whole blood or serum therapy for chronic spontaneous urticaria: A systematic review and meta-analysis
The Journal of dermatological treatment. 2019;:1-28
BACKGROUND Chronic spontaneous urticaria (CSU) is chronic wheals without identifiable exogenous stimuli. Autologous whole blood (AWB) injection and autologous serum therapy (AST) are alternative therapies for CSU that induce tolerance to circulating histamine-releasing factors. OBJECTIVE We elucidated currently available evidence for the efficacy and safety of AWB therapy and AST for CSU. METHODS We systematically searched four databases for eligible studies to perform meta-analysis. The primary outcome was the efficacy of AST or AWB therapy, and the secondary outcome was improvement after intervention based on the autologous serum skin test (ASST) status of patients. RESULTS Eight clinical trials, including four randomized controlled trials and 529 CSU patients, were identified. AST was not more effective than the placebo treatment in alleviating CSU symptoms at the end of treatment (P = 0.161), and AWB injection was also not more effective in response rates than the placebo at the end of follow-up (P = 0.099). Furthermore, the efficacy of AST or AWB injection for CSU and the ASST status were not significantly related. No remarkable adverse events were recorded during therapy. CONCLUSIONS Our meta-analysis suggested that AWB therapy and AST are not significantly more effective in alleviating CSU symptoms than the placebo treatment.
Autologous whole blood or corticosteroid injections for the treatment of epicondylopathy and plantar fasciopathy? A systematic review and meta-analysis of randomized controlled trials
Physical Therapy in Sport : Official Journal of the Association of Chartered Physiotherapists in Sports Medicine. 2016;22:114-122
OBJECTIVES To compare the efficacy of autologous whole blood with that of corticosteroid injections on epicondylopathy and plantar fasciopathy. DESIGN Systematic review and meta-analysis. METHODS The databases of PubMed, Web of Science, CENTRAL, and Scopus were searched up to 6th May 2015. Randomized trials comparing the effects of autologous whole blood and corticosteroid injections on epicondylopathy or plantar fasciopathy were included. Trials exploring the efficacy of platelet-rich plasma were excluded. The primary outcome was pain relief. The secondary outcome included the assessment of composite outcomes. All outcomes were assessed at 2-6 (short-term) weeks, 8-13 (intermediate-term) weeks and 24-26 (medium-term) weeks. Quality assessment was performed with the Cochrane risk of bias tool. RESULTS Nine trials were included. For pain relief, there was a statistically significant difference in favour of corticosteroids in the short term (SMD 0.52; 95%CIs 0.18 to 0.86; I2 = 53%; p < 0.01). A statistically significant difference in favour of autologous whole blood was indicated in the medium-term assessment of pain relief on epicondylopathy. CONCLUSIONS Corticosteroids were marginally superior to autologous whole blood in relieving pain on plantar fasciopathy at 2-6 weeks. Autologous whole blood provided significant clinical relief on epicondylopathy at 8-24 weeks. Conclusions were limited by the risk of bias.
