Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):1155-1160. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.034.

ABSTRACT

OBJECTIVE: To analyze the positive rate and distribution of anti-M unexpected antibody in pediatric inpatients aged 0 to 14 years in central China.

METHODS: A total of 30 049 pediatric inpatients admitted to the Second Xiangya Hospital of Central South University, Wuhan Children’s Hospital and Children’s Hospital Affiliated of Zhengzhou University from May 2020 to August 2022 were enrolled in this study, and relevant clinical data were collected. Blood samples from the patients were tested for blood typing and screened for unexpected antibodies. For samples that screened positive for unexpected antibodies, identification was conducted using the identification panel to determine the specificity of the antibodies. The distribution and differences of anti-M antibodies in pediatric patients of different sexes, ages, blood groups, disease types, with or without a history of blood transfusion, and across different regions were analyzed.

RESULTS: Among 30 049 inpatients, the positive rate of unexpected antibodies was 0.91% (273/30 049), of which the positive rate of anti-M antibodies was 0.44% (131/30 049). The positive rate of anti-M antibodies in the neonates aged 0 to < 1 month was 0.10% (5/4 881), and all of them were IgG antibodies from their mothers; The positive rate of anti-M antibodies for the group aged from 1 month to < 1 year old was 0.23% (7/3 108), with no anti-M antibodies detected in patients aged 1-6 months; The positive rates of anti-M antibodies in the 1-4 years old group, 5-9 years old group, and 10-14 years old group were 0.87% (88/10 064), 0.38% (27/7 190), and 0.08% (4/4 806), respectively. The positive rate of anti-M antibodies in the 1-4 years old group was significantly higher than that of the other groups ( P <0.001), and there were also statistical differences in the positive rate between the 5-9 years old group and the 0-< 1 month and 10-14 years old groups ( P <0.001). The prevalences of anti-M antibodies in ABO blood group A, B, O and AB were 0.32% (30/9 482), 0.70% (58/8 293), 0.32% (31/9 595) and 0.45% (12/2 679), respectively. The prevalence of anti-M antibodies in patients with blood group B was significantly higher than that in patients with blood groups A and O ( P <0.05). The prevalences of anti-M antibodies in Hunan, Hubei and Henan was 0.18%, 0.32% and 0.71%, respectively. The prevalence of anti-M antibodies in Henan was significantly higher than that in Hunan and Hubei ( P <0.05), and the distribution showed obvious regional differences between the north and the south. There were no significant differences in the positive rate of anti-M antibodies between the children with different sexes, disease types, and with or without a history of blood transfusion (P >0.05).

CONCLUSION: This study reveals the distribution pattern of anti-M antibodies in pediatric inpatients aged 0-14 years in central China, which has reference value for the research on unexpected red blood cell antibodies in Chinese children.

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):1131-1137. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.030.

ABSTRACT

OBJECTIVE: To investigate the expression of CSF-1 and CSF-1R in the peripheral blood of children with immune thrombocytopenia (ITP) and its clinical significance.

METHODS: Forty-four children with ITP treated in our hospital from February 2023 to January 2024 were selected as the observation group, and 40 healthy children were selected as the control group during the same period, and relevant clinical data were collected. Peripheral blood mononuclear cells (PBMC) of children with ITP and healthy children were separated, and the plasma levels of M1 macrophage-associated cytokines (TNF-α, IL-6), M2 macrophage-associated cytokines (IL-10, TGF-β), and CSF-1 were detected by ELISA in the children of both groups. The mRNA levels of M1 macrophage surface markers (CD86, iNOS), M2 macrophage surface markers (CD206, Arg-1) and CSF-1R were detected by RT-PCR in PBMC of children in both groups. Western blot was used to detect the expression of CSF-1R protein in PBMC of the two groups of children. The correlation between platelet count and CSF-1R mRNA expression in PBMC, TNF-α, IL-6, IL-10, TGF-β and CSF-1 in plasma was analyzed.

RESULTS: Compared with the control group, the levels of IL-10, TGF-β, CSF-1 and platelet count in plasma of children with ITP were significantly decreased (P < 0.01), and the levels of TNF-α and IL-6 were significantly increased (P < 0.01); the mRNA levels of the M1 macrophage surface markers (CD86, iNOS) in PBMC of children with ITP were significantly increased (P < 0.05), mRNA levels of M2 macrophage surface marker CD206 in PBMC of children with ITP were decreased compared with controls but the difference was not statistically significant ( P >0.05), mRNA levels of Arg-1 were decreased, the difference was statistically significant (P < 0.05). The mRNA and protein levels of CSF-1R in PBMC of ITP children were higher than that in controls. CSF-1R expression in PBMC of ITP was positively correlated with platelet count, IL-10, CSF-1 were positively correlated (r =0.822,0.481,0.405).

CONCLUSION: CSF-1 is significantly reduced in the plasma of ITP, and CSF-1R mRNA and protein expression is significantly elevated in PBMC of ITP, which are involved in the regulation of macrophage M1/M2 imbalance, and could serve as a potential therapeutic target for ITP.

Efficacy Analysis of Stanozolol Combined with Avatrombopag in the Treatment of Chemotherapy-Induced Thrombocytopenia in Relapsed/Refractory Tumors

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):1127-1130. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.029.

ABSTRACT

OBJECTIVE: To investigate the efficacy and safety of stanozolol combined with avatrombopag in the treatment of chemotherapy-induced thrombocytopenia (CIT) in patients with relapsed/refractory tumors.

METHODS: Twenty-five patients with relapsed/refractory CIT admitted to the Hematology Department of Xiyuan Hospital, China Academy of Chinese Medical Sciences between March 2023 to December 2023 were enrolled. These patients received a combined therapy of stanozolol and avatrombopag. The clinical efficacy, onset time, changes in platelet levels and blood cell counts before and after treatment, and adverse reactions of patients were evaluated.

RESULTS: The combination therapy demonstrated remarkable efficacy with a total effective rate of 100%. Among the 25 patients, 19 achieved complete remission and 6 achieved partial remission. The median onset time was 42.5(range: 35-48)days. The average platelet count of the 25 patients increased from (25.73±17.75)×109/L before treatment to (146.4±49.59)×109/L after 3 months of treatment, with a statistically significant difference ( P < 0.05). 18 patients who previously required platelet transfusion were all weaned off platelet transfusion after 3 months of treatment, with a median time to be free from platelet transfusion was 26 (range: 18-51) days. During the treatment, both neutrophils and hemoglobin exhibited various degrees of elevation. Two patients experienced a slight increase in alanine aminotransferase(ALT) levels, which normalized after treatment with oral hepatoprotective drug. One patient had a PLT increase exceeding 350×109/L, and the treatment with avatrombopag was suspended, and aspirin and other drugs were given to prevent thrombosis. No thrombose events or CIT-related bleeding events were observed in all patients.

CONCLUSION: The combination therapy of stanozolol and avatrombopag is significantly effective for treating relapsed/refractory CIT patients, with a high response rate and good safety, making it a suitable clinical treatment option.

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):1098-1103. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.025.

ABSTRACT

OBJECTIVE: To retrospectively analyze the genetic differences of thalassemia gene mutations among ethnic groups in Hechi, Guangxi.

METHODS: A total of 15 595 whole blood samples of residents of Hechi from January 1, 2020 to June 30, 2023 were screened for thalassemia, and the Gap-PCR method and RDB-PCR method were used to perform genetic testing on the positive samples. Gene sequencing was performed on the samples with positive screening results but negative genotyping results.

RESULTS: Among the 15 595 samples, 10 501 cases were screened positively, and 8 506 cases were thalassemia gene carriers among the positive samples, with a positive coincidence rate of 81.00%. Among them, there were 5 374 cases of α-thalassemia, 2 531 cases of β-thalassemia, and 601 cases of α+β compound thalassemia. A total of 13 mutant types were detected in α-thalassemia, including —SEA (48.57%), –α 3.7 (31.31%), α CS (8.57%) and –α 4.2 (8.07%). A total of 17 mutant types were detected in β-thalassemia, mainly CD17 (48.27%) and CD41-42 (41.24%). The thalassemia gene carriers were mainly from the Zhuang (6 106 cases), Han (969 cases), Yao (793 cases), Mulam (275 cases), and Maonan (228 cases) ethnic groups. The comparison of constituent ratios within the above five ethnic groups demonstrated that there were differences in the proportions of — SEA, –α 3.7, α CS , and –α 4.2 among the Zhuang, Han, and Yao ethnic groups (P < 0.005). The proportion of α CS in the Mulam ethnic group was not significantly different from –α 3.7 and –α 4.2. The proportions of — SEA, -α3.7, and α CS in the Maonan ethnic group were not significantly different. There were no significant differences in the proportion of CD17 and CD41-42 among the Han, Yao, Mulam and Maonan ethnic groups. The proportion of —SEA was the highest in the Mulam ethnic group (56.68%), which was statistically different from 35.92% in the Maonan ethnic group. The proportion of –α 3.7 was the highest in the Zhuang ethnic group (33.25%), and the difference was statistically significant compared to the Mulam ethnic group which had the lowest proportion (18.72%). The proportion of α CS was the highest in the Maonan ethnic group (27.46%), and the differences were statistically significant compared with other ethnic groups. The proportions of CD17 in the Zhuang and Maonan ethnic groups (50.79%, 55.68%) were higher than those in the Han (39.12%), Yao (39.63%) and Mulam (30.00%), and the differences were statistically significant. There was no significant difference in the proportion of CD41-42 among the above five ethnic groups.

CONCLUSIONS: The mutation type and distribution differences of genes causing thalassemia among main ethnic groups in the minority inhabited areas of Hechi, Guangxi, show the characteristics of ethnic differentiation. The result is helpful to develop a special prevention and control plan for thalassemia in line with the population distribution characteristics, and provide reference for revealing the genetic background and geographical distribution of thalassemia in this area.

Correlation Analysis of Inflammatory Indexes and Bone Marrow Cytological Characteristics with Prognosis in Patients with Hemophagocytic Lymphohistiocytosis

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):1086-1093. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.023.

ABSTRACT

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with hemophagocytic lymphohistiocytosis (HLH).

METHODS: Clinical data of 78 patients with HLH admitted to Gansu Provincial People’s Hospital from January 2014 to May 2023 were collected, and the correlation between relevant indicators and patient prognosis was analyzed.

RESULTS: Among the 78 HLH patients, there were 48 males and 30 females, with a median age of onset of 48 (1-84) years old; 26 patients were treated with chemotherapy, 44 patients were treated with glucocorticoids, immunoglobulin or cyclosporine, 5 patients received symptomatic treatment, 1 patient received plasma exchange, and 2 patients refused treatment. By the end of the follow-up, there were 39 survivors, 35 deaths, and 4 patients lost to follow-up. There was no significant correlation between sex, ferritin, triglycerides, hemophagocytosis, bone marrow cellularity, Epstein-Barr virus (EBV) infection, SUV value of PET-CT, alanine aminotransferase (ALT), interleukin-6 (IL-6), platelet-to-lymphocyte ratio (PLR) and overall survival (OS) of the patients (P >0.05). Patients with age≥60 years, neutrophil-to-lymphocyte ratio (NLR) >0.59, red cell distribution width-to-platelet ratio (RPR) >0.30, lymphocyte-to-monocyte ratio (LMR)≤2.74, red blood cell distribution width (RDW)>16.45%, tumor-associated HLH, aspartate aminotransferase (AST)≥148 U/L, procalcitonin (PCT)≥0.66 ng/ml, neutrophils (NEU) <2×109/L, fibrinogen (FIB)<1.85 g/L, lactate dehydrogenase (LDH)≥1 740 U/L, hemoglobin (Hb)<85 g/L, platelet (PLT)<57×109/L had significantly shorter OS, with statistical significance (P < 0.05). Multivariate analysis showed that LMR≤2.74, RDW>16.45%, LDH≥1 740 U/L, and NEU<2×109/L were independent risk factors affecting OS in HLH patients (P < 0.05).

CONCLUSION: Some blood-based inflammatory markers are significantly associated with OS in patients with HLH. NLR, RPR, LMR, RDW and PCT can be used to assess the prognosis of HLH patients, and RDW and LMR are independent factors affecting OS of HLH patients, which provide greater predictive value for prognosis. Hypercellular bone marrow in HLH patients may indicate a poor prognosis.

Prognostic Significance of Inflammation Score and Nutrition -Immunity Score in Patients with Newly Diagnosed Multiple Myeloma

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):1069-1078. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.021.

ABSTRACT

OBJECTIVE: To construct the inflammation score (IS) and nutrition-immunity score (NIS) for patients with multiple myeloma (MM), and to verify their prognostic stratification effects and significance.

METHODS: The clinical data of 129 newly diagnosed MM patients admitted to our hospital from August 2011 to September 2022 were retrospectively analyzed. Univariate and multivariate Cox regression analysis of overall survival (OS) were comducted on clinical parameters, including inflammatory indicators such as red blood cell volume distribution width (RDW) and platelet count (PLT), nutritional-immune indicators such as albumin (ALB), absolute lymphocyte count (ALC), and suppressed immunoglobulin count (S-Ig count). To construct IS and NIS for prognosis, X-tile software and multivariate Cox regression analysis were used to verify the prognostic stratification role and significance of IS and NIS. The time-dependent receiver operating characteristic (ROC) curve, C-index curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the discrimination, accuracy, and clinical net benefit of IS and NIS in predicting overall survival(OS), and compared to the international staging system (ISS).

RESULTS: IS was constructed based on the scores of RDW and PLT, and NIS was constructed based on the scores of ALB, ALC, and S-Ig count. According to X-tile analysis and multivariate Cox regression analysis, IS and NIS can divide the patients into three risk strata respectively: low, medium and high IS and NIS groups. The differences in OS and hazard ratio (HR) between the low, medium, and high strata were statistically significant (P < 0.05). IS and NIS are both independent prognostic predictors for MM. The area under the ROC curve (AUC) and C index of IS and NIS for predicting 1- to 7-year OS were greater than those of ISS, and both were greater than 0.7. The prediction results of IS and NIS for 1-, 3-, and 5-year OS rates were well consistent with the actual observed results. The DCA curves of IS and NIS for predicting 1-, 3-, and 5-year OS were higher than that of ISS in a wide range of threshold probability intervals.

CONCLUSION: IS and NIS have independent predictive significance for OS in MM patients. Their predictive discrimination, accuracy, and clinical net benefit are higher and better than ISS, and they may have potential application value in MM prognosis.

The Relationship between Ig Class Switch Recombination and MMR Protein, Microsatellite Phenotype in Extranodal Marginal Zone Lymphoma of Mucosa-associated Lymphoid Tissue

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):1036-1041. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.015.

ABSTRACT

OBJECTIVE: To investigate the relationship between Ig class switch recombination (CSR) and mismatch repair (MMR) protein, microsatellite phenotype in extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma).

METHODS: Forty cases of MALT lymphoma archived in the Department of Pathology, Jiading District Central Hospital, Shanghai University of Medicine & Health Sciences were selected as the observation group, and twenty cases of benign lymphoid tissue hyperplasia were as the control group. The expressions of IgG, IgM, IgD, and IgA in both groups were detected by immunohistochemical double staining, and MMR proteins including MLH1, MSH2, MSH6, and PMS2 in both groups were detected by immunohistochemistry. Multiplex fluorescence PCR capillary electrophoresis was used to detect microsatellite phenotype in tumor and adjacent tissues of the experimental group.

RESULTS: In the observation group, the proportions of single Ig heavy chain expression (modeⅠ), negative expression (modeⅡ), and multiple expression (mode Ⅲ) were 65% (26/40), 27.5% (11/40), and 7.5% (3/40), respectively, while in the control group were 0 (0/20), 5% (1/20), and 95% (19/20). The proportion of Ig heavy chain expression mode Ⅰ+Ⅱ in the observation group was 92.5%, which was significantly higher than 5% in the control group (P < 0.01). In the observation group, partial deletion of MMR protein was observed in 3 cases (7.5%), including 2 cases of MSH6 deletion and 1 case of both MSH6 and PMS2 deletion. In the control group, there was 1 case (5%) with PMS2 deletion. There was no significant difference in the deletion rate of MMR protein between the two groups ( P >0.05). A total of 5 cases of microsatellite instability (MSI) were detected in the observation group, including 1 case of low-frequency MSI (MSI-L), 4 cases of high-frequency MSI (MSI-H), and 2 cases of MSI-H with MSH6 deletion. When the loss expression of MSI-H or MMR protein was counted as a positive result, the MSI-H rate detected by PCR capillary electrophoresis was 10% (4/40), which was slightly higher than the MMR protein deletion rate detected by immunohistochemistry (7.5%, 3/40), but there was no statistically significant difference between the two groups (P >0.05). The MMR protein deletion rates among the Ig heavy chain protein expression mode Ⅰ, mode Ⅱ, and mode Ⅲ groups were 0 (0/26), 18.2% (2/11), and 33.3% (1/3), respectively. There was a statistically significant difference in the constituent ratios among the three groups (P < 0.05). The MMR protein deletion rates among the MSS, MSI-L, and MSI-H groups were 2.9% (1/35), 0 (0/1), and 50% (2/4), respectively. There was a statistically significant difference in the constituent ratios among the three groups (P < 0.05). MMR protein deficiency was positively correlated with Ig heavy chain expression pattern and MSI ( r =0.41, P < 0.05; r =0.48, P < 0.05), but Ig heavy chain expression pattern was not correlated with MSI ( r =0.02, P >0.05).

CONCLUSION: Ig heavy chain CSR detection is helpful for the differential diagnosis of MALT lymphoma. Low frequency MMR protein deletion and MSI-H phenotype exist in MALT lymphoma, which may be of certain value for the study of its occurrence, development and clinical treatment.

Clinical Characteristics and Prognosis of B-cell Acute Lymphoblastic Leukemia Patients with IKZF1 Deletion

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):966-971. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.006.

ABSTRACT

OBJECTIVE: To analyze clinical characteristics and prognosis of B-cell acute lymphoblastic leukemia (B-ALL) patients with IKZF1 deletion.

METHODS: 72 patients with B-ALL admitted to our hospital from April 2020 to January 2023 were selected, IKZF1 deletion were detected, and clinical characteristics and prognosis were analyzed.

RESULTS: Among the 72 patients, a total of 32 patients (44.4%) were identified with IKZF1 deletions (IKZF1 + ). There was no statistically significant difference in basic clinical data between patients with normal IKZF1 (IKZF1 ) and those with IKZF1 + (P >0.05). The proportion of patients with IKZF1 + in Ph+ group was significantly higher than that in Ph group (P < 0.05). The main types of IKZF1 + were exon 1-8 deletion (34.4%) and exon 4-7 deletion (31.2%). The median OS and PFS of IKZF1 patients were significantly longer than those of IKZF1 + patients (OS: 26.0 months vs 16.0 months, χ 2=23.094, P < 0.05; PFS: 26.0 months vs 16.0 months, χ 2=11.150, P < 0.05). Among IKZF1 + patients, the median OS of patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) was significantly longer than that of patients who did not receive allo-HSCT (no reached vs 15.0 months, χ 2=5.685, P < 0.05).

CONCLUSION: IKZF1 deletion is a risk factor affecting the prognosis of B-ALL patients.

The Molecular Mechanism of HCQ Reversing Immune Mediators Dysregulation in Severe Infection after Chemotherapy in Acute Myeloid Leukemia and Inducing Programmed Death of Leukemia Cells

Zhongguo Shi Yan Xue Ye Xue Za Zhi. 2025 Aug;33(4):931-938. doi: 10.19746/j.cnki.issn.1009-2137.2025.04.001.

ABSTRACT

OBJECTIVE: To explore the effects of hydroxychloroquine (HCQ) on immune mediators dysregulation in severe infection after chemotherapy in acute myeloid leukemia (AML) and its molecular mechanism.

METHODS: Bone marrow or peripheral blood samples of 36 AML patients with severe infection (AML-SI) and 29 AML patients without infection (AML-NI) after chemotherapy were collected from the First Affiliated Hospital of Gannan Medical University from August 2022 to June 2023. In addition, the peripheral blood of 21 healthy subjects from the same period in our hospital was selected as the control group. The mRNA expressions of CXCL12, CXCR4 and CXCR7 were detected by RT-qPCR technology, and the levels of IL-6, IL-8 and TNF-α were detected by ELISA. Leukemia-derived THP-1 cells were selected and constructed as AML disease model. At the same time, bone marrow mesenchymal stem cells (BM-MSCs) from AML-SI patients were co-cultured with THP-1 cells and divided into Mono group and Co-culture group. THP-1 cells were treated with different concentration gradients of HCQ. The cell proliferation activity was subsequently detected by CCK-8 method and apoptosis was detected by Annexin V/PI double staining flow cytometry. ELISA was used to detect the changes of IL-6, IL-8 and TNF-α levels in the supernatant of the cell co-culture system, RT-qPCR was used to detect the mRNA expression changes of the core members of the CXCL12-CXCR4/7 regulatory axis, and Western blot was used to detect the expressions of apoptosis regulatory molecules and related signaling pathway proteins.

RESULTS: CXCL12, CXCR4, CXCR7, as well as IL-6, IL-8, and TNF-α were all abnormally increased in AML patients, and the increases were more significant in AML-SI patients (P <0.01). Furthermore, there were statistically significant differences between AML-NI patients and AML-SI patients (all P <0.05). HCQ could inhibit the proliferation and induce the apoptosis of THP-1 cells, but the low concentration of HCQ had no significant effect on the killing of THP-1 cells. When THP-1 cells were co-cultured with BM-MSCs of AML patients, the levels of IL-6, IL-8 and TNF-α in the supernatance of Co-culture group were significantly higher than those of Mono group (all P <0.01). After HCQ intervention, the levels of IL-6, IL-8 and TNF-α in cell culture supernatant of Mono group were significantly decreased compared with those before intervention (all P <0.01). Similarly, those of Co-culture group were also significantly decreased (all P <0.001). However, the expression of the core members of the CXCL12-CXCR4/7 regulatory axis was weakly affected by HCQ. HCQ could up-regulate the expression of pro-apoptotic protein Bax, down-regulate the expression of anti-apoptotic protein Bcl-2, as well as simultaneously promote the hydrolytic activation of Caspase-3 when inhibiting the activation level of TLR4/NF-κB pathway, then induce the programmed death of THP-1 cells after intervention.

CONCLUSION: The core members of CXCL12-CXCR4/7 axis and related cytokines may be important mediators of severe infectious immune disorders in AML patients. HCQ can inhibit cytokine levels to reverse immune mediators dysregulation and suppress malignant biological characteristics of leukemia cells. The mechanisms may be related to regulating the expression of Bcl-2 family proteins, hydrolytically activating Caspase-3 and inhibiting the activation of TLR4/NF-κB signaling pathway.

The Optimal Dose, Efficacy and Safety of Tranexamic Acid on Hemorrhage Control for High Tibial Osteotomy: A Network Meta-Analysis

Orthop Surg. 2025 Sep 11. doi: 10.1111/os.70140. Online ahead of print.

ABSTRACT

OBJECTIVE: This systematic review and network meta-analysis was performed to explore the optimal dose, efficacy, and safety of tranexamic acid (TXA) treatments versus placebo for high tibial osteotomy (HTO) patients.

METHODS: PubMed, Embase, Cochrane Library, Wanfang database, and Chinese National Knowledge Infrastructure (CNKI) databases were searched for the randomized controlled trials (RCTs) meeting prespecified inclusion criteria up to March 2024. Interventions included TXA and placebo treatments. The outcomes included total blood loss, drainage, hemoglobin drop, the occurrence of deep venous thrombosis (DVT) and hematoma. Traditional meta-analysis and network meta-analysis were performed by Stata and R software, respectively.

RESULTS: Traditional meta-analysis revealed that TXA was associated with a decrease in the total blood loss, drainage volume, and hemoglobin drop (p < 0.05). There was no significant difference between TXA and placebo in terms of the occurrence of DVT and hematoma (p > 0.05). Compared with placebo, intravenous (iv) 10 mg/kg, iv 10 mg/kg (3 doses), iv 2 g, iv 2 g (2 doses), iv 2 g + topical (top) 3 g, iv 50 mg/kg, and top 10 mg/kg decreased the total blood loss with statistical significance (p < 0.05). Compared with placebo, iv 10 mg/kg (WMD = -379.91, 95% CI: -378.92, -81.22) decreased the drainage volume with statistical significance. Compared with placebo, iv 10 mg/kg (3 doses), iv 1 g, iv 1 g + top 2 g, iv 2 g + top 1 g, and iv 50 mg/kg decreased the hemoglobin drop with statistical significance. No statistically significant difference was found when the two interventions were compared against each other for the occurrence of DVT and hematoma (p > 0.05). The SUCRA shows that iv 10 mg/kg ranked first for reducing total blood loss (SUCRA, 90.7%) and drainage volume (SUCRA, 94.3%). The SUCRA shows that iv 1 g + top 2 g ranked first (SUCRA, 93.7%) for reducing hemoglobin drop.

CONCLUSION: Administration with TXA was associated with a decrease in blood loss in HTO patients. The optimal dose of TXA for reducing blood loss was iv 10 mg/kg. As for reducing hemoglobin drop, iv 1 g + top 2 g ranked first. Administration of TXA was not associated with an increase in the occurrence of DVT and hematoma. However, most evidence was graded as low/very low confidence due to study limitations, imprecision, and heterogeneity. Therefore, these findings should be interpreted as preliminary signals rather than definitive conclusions. Further high-quality randomized trials are required to validate dose-dependent efficacy and long-term safety outcomes.
