Tranexamic acid has been shown to reduce rebleeding after aneurysmal subarachnoid hemorrhage; however, whether it can reduce mortality and improve clinical outcomes is controversial. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of the tranexamic acid in aneurysmal subarachnoid hemorrhage. We conducted a comprehensive literature search of PubMed, Embase, Web of Science, and Cochrane Library from inception to March 2021 for randomized controlled trials (RCTs) comparing tranexamic acid and placebo in adults with aneurysmal subarachnoid hemorrhage. The risk of bias was evaluated using the Cochrane Handbook, and the quality of evidence was evaluated using the GRADE approach. This meta-analysis included 13 RCTs, involving 2,888 patients. In patients with aneurysmal subarachnoid hemorrhage tranexamic acid had no significant effect on all-cause mortality (RR = 0.96; 95% CI = 0.84–1.10, p = 0.55, I2 = 44%) or poor functional outcome (RR = 1.04; 95% CI = 0.95–1.15, p = 0.41) compared with the control group. However, risk of rebleeding was significantly lower (RR = 0.59; 95% CI = 0.43–0.80, p = 0.0007, I2 = 53%). There were no significant differences in other adverse events between tranexamic acid and control treatments, including cerebral ischemia (RR = 1.17; 95% CI = 0.95–1.46, p = 0.15, I2 = 53%). At present, routine use of tranexamic acid after subarachnoid hemorrhage cannot be recommended. For a patient with subarachnoid hemorrhage, it is essential to obliterate the aneurysm as early as possible. Additional higher-quality studies are needed to further assess the effect of tranexamic acid on patients with subarachnoid hemorrhage.

Abstract Background: Tranexamic acid, as a traditional hemostatic agent, is commonly applied in the treatment or prevention of excessive blood loss. However, the role of tranexamic acid in promoting good clinical outcomes, reducing mortality, and the risk of experiencing adverse events during the therapeutic process of aneurysmal subarachnoid hemorrhage remains unclear.Methods: In strict accordance with the inclusion and exclusion criteria, the Cochrane Library, Embase, Web of Science, and PubMed were retrieved for randomized-controlled trials (from 1980 to 2021). Statistical analysis was performed using STATA 16.0 and RevMan 5.3. In addition, the fixed-effect model (M-H method) and effect size RR (95% CI) were used as a pooled measure to combine the heterogeneous data. We also performed post hoc sensitivity analysis and subgroup analysis to evaluate each outcome with low heterogeneity.Results: Meta-analysis revealed that although tranexamic acid was related to less rebleeding (RR = 0.72; 95% CI 0.59-0.87; P = 0.0008), it might have no effect on good clinical outcome or mortality (RR = 0.98; 95% CI 0.92-1.04; P = 0.51; RR = 1.01; 95% CI 0.88-1.15; P = 0.91). Tranexamic acid was associated with increased hydrocephalus (RR = 1.13; 95% CI 1.02-1.24; P = 0.02), delayed cerebral ischemia (RR = 1.70; 95% CI 1.34-2.16; P < 0.0001) and seizure (RR = 1.46; 95% CI 1.00-2.14; P = 0.05). The incidence of thromboembolic complications was identical in both groups (RR = 0.91; 95% CI 0.63-1.31; P = 0.62), and there were significant drug-related overall adverse events (RR = 1.21; 95% CI 1.11- 1.32; P < 0.0001).Conclusions: These findings indicate that the routine use of TXA is not suggested for patients with aneurysmal subarachnoid hemorrhage.

Background: Melasma is an acquired pigmentation disorder with challenges in treatment because of its refractory nature and high risk of recurrence.Objectives: This study aimed to compare the efficacy and side effects of 14 common therapies for melasma using a systematic review and network meta-analysis (NMA).Methods: The PubMed, Embase, and Cochrane Library databases were searched till December 2020 using the melasma area and severity index as a therapeutic index. A total of 59 randomized controlled trials (RCTs) met the inclusion criteria and were selected.Results: The ranking of relative efficacy compared with placebo in descending order was Q-switched Nd:Yag 1,064-nm laser (QSND), intense pulsed light, ablative fractional laser (AFL), triple combined cream (TCC), topical vitamin C, oral tranexamic acid (oTA), peeling, azelaic acid, microneedles (MNs), topical tranexamic acid (tTA), tretinoin, picosecond laser, hydroquinone (HQ), and non-AFL. Moreover, QSND was more effective than HQ and tTA against melasma. The ranking of percentage (%) of side effects in ascending order for each of 14 therapies with more than 80 participants was tretinoin (10.1%), oTA (17.6%), HQ (18.2%), AFL (20.0%), QSND (21.5%), TCC (25.7%), tTA (36.75%), peeling (38.0%), and MN (52.3%). Taking both efficacy and safety into consideration, TCC was found to be the most favorable selection among the topical drugs for melasma. QSND and AFL were still the best ways to treat melasma among photoelectric devices. oTA as system administration was a promising way recommended for melasma. Among 31 studies, 87% (27/31) studies showed that the efficacy of combination therapies is superior to that of single therapy. The quality of evidence in this study was generally high because of nearly 50% of split-face RCTs.Conclusions: Based on the published studies, this NMA indicated that QSND, AFL, TCC, and oTA would be the preferred ways to treat melasma for dermatologists. However, more attention should be paid to the efficacy and safety simultaneously during the clinical application. Most of the results were in line with those of the previous studies, but a large number of RCTs should be included for validation or update.Systematic Review Registration: identifier: CRD42021239203.

Background: Crohn disease (CD) is a chronic inflammatory disease that affects quality of life. There are several drugs available for the treatment of CD, but their relative efficacy is unknown due to a lack of high-quality head-to-head randomized controlled trials.Aim: To perform a mixed comparison of the efficacy and safety of biosimilars, biologics and JAK1 inhibitors for CD.Methods: We searched PubMed, Web of Science, embase and the Cochrane Library for randomized controlled trials (RCTs) up to Dec. 28, 2020. Only RCTs that compared the efficacy or safety of biosimilars, biologics and JAK1 inhibitors with placebo or another active agent for CD were included in the comparative analysis. Efficacy outcomes were the induction of remission, maintenance of remission and steroid-free remission, and safety outcomes were serious adverse events (AEs) and infections. The Bayesian method was utilized to compare the treatments. The registration number is CRD42020187807.Results: Twenty-eight studies and 29 RCTs were identified in our systematic review. The network meta-analysis demonstrated that infliximab and adalimumab were superior to certolizumab pegol (OR 2.44, 95% CI 1.35–4.97; OR 2.96, 95% CI 1.57–5.40, respectively) and tofacitinib (OR 2.55, 95% CI 1.27–5.97; OR 3.10, 95% CI 1.47–6.52, respectively) and revealed the superiority of CT-P13 compared with placebo (OR 2.90, 95% CI 1.31–7.59) for the induction of remission. Infliximab (OR 7.49, 95% CI 1.85–34.77), adalimumab (OR 10.76, 95% CI 2.61–52.35), certolizumab pegol (OR 4.41, 95% CI 1.10–21.08), vedolizumab (OR 4.99, 95% CI 1.19–25.54) and CT-P13 (OR 10.93, 95% CI 2.10–64.37) were superior to filgotinib for the maintenance of remission. Moreover, infliximab (OR 3.80, 95% CI 1.49–10.23), adalimumab (OR 4.86, 95% CI 1.43–16.95), vedolizumab (OR 2.48, 95% CI 1.21–6.52) and CT-P13 (OR 5.15, 95% CI 1.05–27.58) were superior to placebo for steroid-free remission. Among all treatments, adalimumab ranked highest for the induction of remission, and CT-P13 ranked highest for the maintenance of remission and steroid-free remission.Conclusion: CT-P13 was more efficacious than numerous biological agents and JAK1 inhibitors and should be recommended for the treatment of CD. Further head-to-head RCTs are warranted to compare these drugs.

Background. Clinical investigators have found that the use of needling in the treatment of ankylosing spondylitis (AS) has a good clinical application prospect in recent years. However, these studies were insufficient to provide evidence for the efficacy and safety of simple-needling for AS. So, we performed a systematic review and meta-analysis to evaluate the efficacy and safety of simple-needling for treating AS. Methods. We searched the PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wangfang database (Wanfang), Chinese Science and Technology Periodical Database (VIP), and any other gray literature sources for randomized controlled trials (RCTs) that used simple-needling to treat AS before June 2019 with the language restriction of Chinese and English. Researchers evaluated the retrieved literature studies and extracted valid data according to relevant requirements and used RevMan5.3 software for meta-analysis. Results. A total of 10 studies were included, all of which were Chinese literature studies, involving 729 patients. Compared with the control groups, simple-needling groups had a better effect on the clinical effective rate (RR = 1.20, 95% CI (1.11, 1.29), P<0.00001), TCM syndrome score (MD = −5.26, 95% CI (−5.99, −4.53), P<0.00001), symptom score (MD = −8.08, 95% CI (−10.18, −5.97), P<0.00001), and Schober test outcome (MD = 0.39, 95% CI (0.15, 0.64), P=0.002). Sensibility analysis was based on the leave-one-out cross-validation procedure, and the results showed no significant changes. Most studies did not describe adverse reactions. The funnel plot suggested publication bias on clinical effectiveness. Conclusions. This systematic review and meta-analysis demonstrated that simple-needling was effective as an intervention for AS. However, due to the low quality of the methodology of included studies, the designs of clinical trials were not rigorously standardized. Therefore, it is necessary to carry out multiquality RCTs for verification.
