Abstract: Objective: To systematically evaluate the clinical efficacy of autohemotherapy acupoint injection for allergic rhinitis (AR). Methods:Studies on autohemotherapy acupoint injection for AR were retrieved from PubMed, Cochrane Library,Web of Science,China National Knowledge Infrastructure(CNKI),China Science and Technology Journal Database (VIP), Wanfang Data Knowledge Service Platform (Wanfang), and China Biology Medicine disc (CBM) databases from inception of each database to May 1, 2025. Two reviewers independently screened the retrieved literature and extracted valid data. Meta-analysis was performed using RevMan 5.4 software. Results:A total of 27 studies involving 2 187 patients were included. Meta-analysis results showed that autohemotherapy acupoint injection alone [OR=3.64,95%CI (2.25,5.89),P<0.000 01] and its combination with other therapies [OR=3.18, 95%CI (2.34,4.32),P<0.000 01] significantly improved the total clinical effective rate. Autohemotherapy acupoint injection was superior to the control group in increasing interferon-γ (IFN-γ) [MD=3.04,95%CI (2.04,4.04),P< 0.000 01] and interleukin-12 (IL-12) [MD=3.03,95%CI (1.70,4.35),P<0.000 01];alleviating nasal symptoms including sneezing [MD=−0.31,95%CI (−0.37,−0.26),P<0.000 01],rhinorrhea [MD=−0.51,95%CI (−0.57, −0.44),P<0.000 01],nasal congestion [MD=−0.54,95%CI (−0.69,−0.40),P<0.000 01],nasal itching [MD= −0.41,95%CI (−0.55,−0.28),P<0.000 01],and nasal mucosal swelling [MD=−0.46,95%CI (−0.64,−0.29), P<0.000 01];and improving Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores in daily activities [MD= −1.24,95%CI( −1.96,−0.52),P=0.000 8],sleep [MD=−1.44,95%CI( −2.10,−0.78),P<0.000 1],non-nasal/ ocular symptoms [MD=−1.90,95%CI( −3.41,−0.40),P=0.01],behavioral problems [MD=−1.86,95%CI( −2.24, −1.48),P<0.000 01],nasal symptoms [MD=−2.36,95%CI (−2.97,−1.74),P<0.000 01],emotional response [MD=−1.45,95%CI (−2.14,−0.76),P<0.000 1],and ocular symptoms [MD=−0.50,95%CI (−0.60,−0.40), P<0.000 01]. However,there were no statistically significant differences compared with the control group in improving immunoglobulin E levels [MD=−58.10,95%CI( −123.56,7.36),P=0.08] or interleukin-4( IL-4) levels [MD=−0.87, 95%CI ( − 1.74, 0.00), P=0.05]. Conclusion: Autohemotherapy acupoint injection is more effective than conventional western medicine or conventional Chinese medicine alone,and significantly improves nasal symptoms and quality of life,increases serum IFN-γ and IL-12 levels,and has a favorable safety profile.
