Project description:BackgroundDachaihu Decoction (DCD) is a traditional herbal formula widely used for treating acute pancreatitis (AP) in China. However, the efficacy and safety of DCD has never been validated, limiting its application. This study will assess the efficacy and safety of DCD for AP treatment.MethodsRelevant randomized controlled trials of DCD in treating AP will be searched through Cochrane Library, PubMed, Embase, Web of Science, Scopus, CINAHL, China National Knowledge Infrastructure database, Wanfang Database, VIP Database, and Chinese Biological Medicine Literature Service System database. Only studies published between the inception of the databases and May 31, 2023 shall be considered. Searches will also be performed in the WHO International Clinical Trials Registry Platform, Chinese Clinical Trial Registry, and ClinicalTrials.gov. Preprint databases and grey literature sources such as OpenGrey, British Library Inside, ProQuest Dissertations & Theses Global, and BIOSIS preview will also be searched for relevant resources. The primary outcomes to be assessed will include mortality rate, rate of surgical intervention, proportion of patients with severe acute pancreatitis transferred to ICU, gastrointestinal symptoms, and the acute physiology and chronic health evaluation II score. Secondary outcomes will include systemic complications, local complications, the normalization period of C-reactive protein, length of stay in the hospital, TNF-α, IL-1, IL-6, IL-8, and IL-10 levels, and adverse events. Study selection, data extraction, and assessment of bias risk will be conducted independently by two reviewers using the Endnote X9 and Microsoft Office Excel 2016 software. The risk of bias of included studies will be assessed by the Cochrane "risk of bias" tool. Data analysis will be performed using the RevMan software (V.5.3). Subgroup and sensitivity analysis will be performed where necessary.ResultsThis study will provide high-quality current evidence of DCD for treating AP.ConclusionThis systematic review will provide evidence of whether DCD is an effective and safe therapy for treating AP.Trial registrationPROSPERO registration number CRD42021245735.

Project description:Background: Type 2 diabetes mellitus (T2DM) is a clinical metabolic syndrome characterized by persistent hyperglycemia, which is caused by defective insulin secretion and decreased function in regulating glucose metabolism. Dachaihu Decoction (DCHD) is a traditional Chinese medicine formula that has been gradually used in T2DM treatment. A comprehensive analysis on the efficacy and safety of DCHD in T2DM treatment is necessary. Objective: This meta-analysis aimed to systematically assess the clinical efficacy and safety of DCHD in the T2DM treatment and provide a reference for subsequent research and clinical practice. Methods: Both Chinese and English databases were searched from their inceptions to November 2021. All retrieved studies were screened according to inclusion and exclusion criteria and randomized controlled trials about DCHD on T2DM were enrolled. The quality of the literature was assessed using the bias risk assessment tool in the Cochrane Handbook. Data extraction was performed on the selected studies. Review Manager 5.4 and Stata 16.0 were used for meta-analysis. Sources of heterogeneity were also explored by using meta-regression and subgroup analysis. Funnel plot and Egger's test were used to assess publication bias and the evidence quality was assessed by GRADE. Results: 17 eligible studies, involving 1,525 patients, were included in this study. Compared with conventional treatment, combined treatment with DCHD was significantly better in improving HbA1c (MD = -0.90%, 95%CI: -1.20 to -0.60, p < 0.01), FBG (MD = -1.08 mmol/L, 95%CI: -1.28 to -0.87, p < 0.01), 2hPG (MD = -1.25 mmol/L, 95%CI: -1.42 to -1.09, p < 0.01), TC (MD = -0.50 mmol/L, 95%CI: -0.70 to -0.30, p < 0.01), TG (MD = -0.44 mmol/L, 95%CI: -0.61 to -0.26, p < 0.01), LDL-C (MD = -0.58 mmol/L, 95%CI: -0.85 to -0.31, p < 0.01), HOMA-IR (SMD = -2.04, 95%CI: -3.09 to -0.99, p < 0.01), HOMA-β (SMD = 2.48, 95%CI: 2.20 to 2.76, p < 0.01) and BMI (MD = -1.52 kg/m2, 95%CI: -2.55 to -0.49, p < 0.01). When DCHD used alone, it had a similar efficacy to conventional treatment in HbA1c (MD = -0.04%, 95%CI: -0.17 to 0.09, p = 0.57) and FBG (MD = 0.13 mmol/L, 95%CI: -0.09 to 0.36, p = 0.24). It can also reduce 2hPG, even if not as effective as conventional treatment (MD = 0.54 mmol/L, 95%CI: 0.19 to 0.89, p < 0.01). Due to the small number of included studies, it is unclear whether DCHD used alone has an improving effect on lipid metabolism, BMI, HOMA-IR and HOMA-β. Analysis of adverse events showed DCHD was relatively safe. No obvious publication bias was detected by Funnel plot and Egger's test. Conclusion: Based on this meta-analysis, we found that the combination with DCHD in the T2DM treatment has more advantages than conventional treatment alone, which can further regulate the glucose and lipid metabolism, reduce insulin resistance, improve islet function and lower BMI. DCHD alone also plays a certain role in regulating glucose. Meanwhile, DCHD is relatively safe. However, limited by the quality and quantity of included studies, the efficacy and safety of DCHD remain uncertain. More high-quality studies are still needed to provide more reliable evidence for the clinical application of DCHD.

Project description:Introduction: The use of Wendan decoction (WDD) as a therapy for nonalcoholic fatty liver disease (NAFLD) has been studied in many clinical trials, and some of them showed that WDD is effective for treating this condition. However, no comprehensive research to evaluate the clinical efficacy of WDD in NAFLD patients had been performed. This systematic review and meta-analysis sought to provide an in-depth inquiry into the data currently available about the safety and effectiveness of WDD to treat NAFLD. Methods: We examined the primary database for any reports of randomized controlled trials (RCTs) including WDD and its effectiveness in treating NAFLD. We used the Jadad rating scale to determine the overall quality of the selected RCTs, and we searched the Cochrane Reviewer's Handbook for criteria for potential bias. The primary findings from the included RCTs were recorded, and the meta-analysis was performed using RevMan5.4 software developed by the Cochrane Collaboration. Results: We retrieved ten RCTs that were suitable for this evaluation and included them in a systematic review and meta-analysis. The quality and risk of bias in the included RCTs were assessed. The meta-analysis showed that the total clinical effective rate was substantially greater in the WDD cohort compared with that in the control cohort, and liver function, blood lipid indices, and blood glucose-related indicators were substantially improved in the WDD-treated cohort compared with those in the control cohort. There was no significant difference in the incidence of adverse events between the two cohorts. Conclusion: WDD is safe and effective for treating NAFLD, which is advantageous for the patients' liver function as well as their blood lipid indices and blood glucose-related indicators.

Project description:ObjectiveClinical trials have recently shown a connection between nonalcoholic fatty liver disease (NAFLD) and empagliflozin. This paper aimed at comprehensively assessing the effectiveness and security of empagliflozin in NAFLD patients.MethodsPubMed, Embase, Web of Science, Cochrane Library, CNKI, CBM, Wan-Fang digital database, VIP, and WHO ICTRP were searched for randomized controlled trials (RCTs) on the role of empagliflozin in NAFLD from inception to November 2, 2021. For continuous dating, we used values of mean differences (MD) to present.ResultsA total of four articles involving 244 NAFLD patients were included. Compared with the control group, empagliflozin could significantly reduce the body mass index (BMI) (MD: -0.98 [95% CI: -1.87, -0.10], p = 0.03), liver stiffness measurement (LSM) (MD: 0.49 [95% CI: -0.93, -0.06], p = 0.03), aspartate aminotransferase (AST) (MD: -3.10 [95% CI: -6.18, -0.02], p = 0.05), homeostasis model assessment of insulin resistance (HOMA-IR) (MD: -0.45 [95% CI: -0.90, 0.00], p = 0.05) of the treatment group.ConclusionsEmpagliflozin can improve body composition, insulin resistance, and liver fibrosis and decrease the hepatic enzymes in patients with NAFLD. Empagliflozin emerges as a new option for treating patients with NAFLD. However, further research shall determine the efficacy and safety of empagliflozin in NAFLD.

Project description:BackgroundDachaihu decoction (Dachaihu tang) plays a crucial role in treating acute illnesses. Recently, a significant number of clinical studies on Dachaihu decoction for acute cholecystitis (AC) have been published. This study was conducted to assess the efficacy and safety of Dachaihu decoction in patients with this condition.MethodsTo identify relevant randomized controlled trials (RCTs), eight databases and three clinical trial registries were searched from inception to 30 June 2024. Two researchers independently screened and extracted data from eligible studies using EndNote X9 and Microsoft Office Excel 2019. RoB 2.0 was used to assess the risk of bias in the included studies. Stata 17.0 was used for data analysis. Publication bias and its impact on result stability were evaluated using a funnel plot and the "trim-and-fill" method. The quality of evidence was graded using the GRADE assessment system.ResultsThirty-three RCTs involving 2,851 participants were included. The treatment group demonstrated improved clinical efficacy (RR = 1.18; 95% CI = 1.13 to 1.24), significantly reduced length of hospital stay (MD = -1.78 days; 95% CI = -2.02 to -1.53), and the incidence of adverse events (RR = 0.31; 95% CI = 0.20 to 0.48). Additionally, there appeared to be reductions in the time for abdominal pain to resolve (MD = -1.92 days; 95% CI = -2.33 to -1.51), fever to disappear (MD = -1.52 days; 95% CI = -1.90 to -1.14), white blood cell count to return to normal (MD = -2.89 days; 95% CI = -3.32 to -2.46), alanine aminotransferase (ALT) levels (MD = -11.88 U/L; 95% CI = -15.29 to -8.47), aspartate aminotransferase (AST) levels (MD = -8.74 U/L; 95% CI = -9.76 to -7.72), neutrophil percentage (MD = -9.68; 95% CI = -11.33 to -8.03), TNF-α levels (SMD = -2.10 pg/L; 95% CI = -2.43 to -2.78), and certainty of evidence (moderate-to-low certainty).ConclusionDachaihu decoction may be an effective botanical formula for managing AC and a lower incidence of adverse events. However, due to the substantial risk of bias and heterogeneity across the included studies, these findings should be interpreted with caution and require further validation through well-designed, high-quality trials.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=573332.

Project description:IntroductionAcute fatty liver of pregnancy (AFLP) is a fatal disease occurring in 3rd trimester. The safety and efficacy of plasmapheresis/plasma exchange (PP/PE) as an adjunctive treatment in patients of AFLP has been studied. We performed systematic review and meta-analysis to estimate the clinical parameters that included mortality rates and improvement of the biochemical parameters including Liver and Renal function enzymes, coagulopathy factors of AFLP patients.MethodsWe searched PubMed, Ovid MEDLINE, Cochrane, CINAHL and Scopus, ClinicalTrials.gov. RevMan statistical software was used for meta-analysis.ResultsPooled survival proportion for AFLP patients treated with PP/PE was 87.74% (95% CI: 82.84 to 91.65). Efficacy of PP/PE was studied by its effect on mortality. PE/PP was associated with the reduction in the mortality with pooled odds ratio of 0.51 (95% CI: 0.08 to 3.09) with I2 = 86%. Sensitivity analysis after excluding outlier study, yielded a pooled odds ratio of 0.19 (95% CI: 0.02 to 1.52) with reduced heterogeneity (I2 = 63%). Biochemical parameter analysis demonstrated significant improvement post-PP/PE treatment, including decreased bilirubin (MD: 8.30, 95% CI: 6.75 to 9.84), AST (MD: 107.25, 95% CI: 52.45 to 162.06), ALT (MD: 111.08, 95% CI: 27.18 to 194.97), creatinine (MD: 1.66, 95% CI: 1.39 to 1.93), and Prothrombin time (MD: 5.08, 95% CI: 2.93 to 7.22).DiscussionDespite some heterogeneity, PP/PE shows promise in improving biochemical parameters in AFLP patients. PE can serve as a therapeutic approach for AFLP particularly in severe or refractory cases. PE provides the time for organ to recover and helps in creating a homeostatic environment for liver. Large RCTs and propensity matched studies are needed to better understand the safety and efficacy of the treatment.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022315698.

Project description:Although tremendous research has reported the protective effects of natural compounds in nonalcoholic fatty liver disease (NAFLD), there is still no approved drug. This study aimed to examine the efficacy of Panax ginseng in NAFLD in preclinical studies. A total of 41 studies were identified by searching the PubMed, Web of Science, and Cochrane Library databases. The methodological quality was assessed by the risk of bias tool from the Systematic Review Center for Laboratory Animal Experimentation. The standardized mean difference (SMD) with a 95% confidence interval was calculated, and the random effects model was used to examine overall efficacy or heterogeneity. The publication bias was analyzed by Egger's test. The results showed that Panax ginseng treatment significantly reduced the systemic levels of alanine aminotransferase (SMD: -2.15 IU/L; p < 0.0001), aspartate aminotransferase (SMD: -2.86 IU/L; p < 0.0001), triglyceride (SMD: -2.86 mg/dL; p < 0.0001), total cholesterol (SMD: -1.69 mg/dL; p < 0.0001), low-density lipoprotein (SMD: -1.46 mg/dL; p < 0.0001), and fasting glucose (SMD: -1.45 mg/dL; p < 0.0001) while increasing high-density lipoprotein (SMD: 1.22 mg/dL; p = 0.0002) in NAFLD regardless of animal models or species. These findings may suggest that Panax ginseng is a promising therapeutic agent for NAFLD treatment.

Project description:BackgroundThe prevalence of nonalcoholic fatty liver disease (NAFLD) has significantly increased over the last decades. Despite existence of several interventions, there remains unclear which interventions work the best.MethodsA systematic review and network meta-analysis of randomized trials comparing efficacy of all treatment options in NAFLD were performed to determine comparative efficacy and safety of interventions in the management of NAFLD. Several electronic databases were searched up to Nov 15, 2015. Outcomes include liver histological outcomes (i.e., fibrosis), all-cause mortality, cirrhosis, and safety. A network meta-analysis was applied to estimate pooled risk ratios (RR). Quality of evidence was assessed using GRADE criteria.ResultsA total of 44 studies (n?=?3802) were eligible. When compared with placebo, obeticholic acid (OCA) was the only intervention that significantly improved fibrosis with RR (95% CI) of 1.91 (1.15, 3.16), while pentoxyfylline (PTX) demonstrated improved fibrosis without statistical significance with RR (95% CI) of 2.27 (0.81, 6.36). Only thiazolidinedione (TZD) and vitamin E use resulted in significant increase in resolution of NASH, while OCA, TZD, and vitamin E significantly improved other outcomes including NAS, steatosis, ballooning, and inflammation outcomes. Quality of evidence varied from very low (i.e., metformin, PTX on mean change of ballooning grade) to high (OCA, TZD, vitamin E on improving histological outcomes). Limitations of this study were lack of relevant long-term outcomes (e.g., cirrhosis, death, safety), possible small study effect, and few head-to-head studies.ConclusionsOur study suggests potential efficacy of OCA, TZD, and vitamin E in improving histologic endpoints in NAFLD. These findings are however based on a small number of studies. Additional studies are awaited to strengthen this network meta-analysis.

Project description:BACKGROUND & AIMS:Previous studies examining the relationship between the C282Y and H63D HFE mutations and presence of nonalcoholic fatty liver disease (NAFLD) have yielded conflicting results. The goal of this study was to systematically evaluate and summarize data on the association between these two variants and the presence of NAFLD. METHODS:The authors searched EMBASE and PUBMED from August 1, 1996 to August 12, 2010. Two investigators independently conducted data abstraction. Ethnic specific weighted prevalence was calculated and pooled odds ratios were estimated using the random effects model. RESULTS:From 2542 references, the authors included 16 case-control studies and 14 case-only studies, or 2610 cases and 7298 controls. The majority of the studies came from Caucasian populations (2287 cases and 4275 controls). The weighted prevalence of HFE mutations in cases was comparable to controls. The meta-analysis was restricted to Caucasians only because of the small sample size of non Caucasian participants. The pooled odds ratio for the presence of any HFE genetic variant in cases was 1.03 (95%CI: 0.90, 1.17; I(2): 65.8%, 95%CI: 38.5, 81.0). The presence of other genotypes and secondary analyses yielded similar non significant findings. CONCLUSIONS:Our systematic review does not support an association between the HFE genetic variants and the presence of NAFLD.

Project description:Individuals with nonalcoholic fatty liver disease (NAFLD) are characterized by increased cardiovascular risk. Endothelial dysfunction, a mechanism implicated in those processes, may constitute the missing link in this interaction. Therefore, this systematic review and meta-analysis aims to evaluate the association of endothelial dysfunction, assessed by flow-mediated dilation (FMD) of the brachial artery, with NAFLD. We conducted a systematic literature search for studies assessing the difference in FMD between patients with NAFLD and controls. Exclusion criteria consisted of preclinical studies, studies in children/adolescents, no FMD assessment, and the absence of an NAFLD/control group. The database search identified 96 studies. Following the application of the exclusion criteria, 22 studies were included in the meta-analysis (NAFLD: 2164 subjects; control: 3322 subjects). Compared with controls, patients with NAFLD had significantly lower FMD% values (SMD: -1.37, 95% CI -1.91 to -0.83, p < 0.001, I2: 98%). Results remained unaffected after exclusion of any single study. Subgroup analysis revealed significantly decreased FMD in NAFLD subjects diagnosed with liver ultrasound or liver biopsy compared with method combination or other methods, while no differences were observed according to the chosen cuff inflation threshold, the presence of a significant difference in obesity measures between the groups, or the type of the control group (age- and sex-matched vs. other). Funnel plot asymmetry was not observed. Finally, compared with patients with pure steatosis, individuals with nonalcoholic steatohepatitis had significantly lower FMD (SMD: -0.81, 95% CI -1.51 to -0.31, p = 0.003, I2: 81%). In conclusion, FMD of the brachial artery, indicative of endothelial dysfunction, was significantly reduced in subjects with nonalcoholic fatty liver disease. Patients with nonalcoholic steatohepatitis might be facing a more pronounced endothelial impairment.
