Introduction: Approximately 10–20% of patients WITH myasthenia gravis (MG) are refractory to conventional immunotherapies. The purpose of this study was to conduct a systematic review and meta-analysis to explore the optimal therapies for refractory MG.Method: Correlative studies were performed through a search in PubMed, Cochrane Library, and Embase databases. The primary outcome was defined by changes in the quantitative myasthenia gravis score (QMG). Secondary outcomes were defined by the Myasthenia Gravis Activities of Daily Living Scale (MG-ADL), Myasthenia Gravis Foundation of America (MGFA) post intervention status, adverse events, and disease exacerbation after treatment.Result: A total of 16 studies were included with 403 patients with refractory MG on therapies with rituximab, eculizumab, tacrolimus, and cladribine. Therapeutic efficacy of rituximab and eculizumab was identified with an estimated reduction in QMG score (4.158 vs. 6.928) and MG-ADL (4.400 vs. 4.344), respectively. No significant changes were revealed in efficacy or exacerbation density between the two independent therapeutic cohorts. The estimated adverse event density of eculizumab was more significant than that in the rituximab group (1.195 vs. 0.134 per patient-year), while the estimated serious event density was similar.Conclusion: The efficacy and safety of rituximab and eculizumab have been approved in patients with refractory MG. Rituximab had a superior safety profile than eculizumab with a lower incidence of adverse events.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021236818, identifier CRD42021236818.

ObjectivesTo assess the efficacy and safety of omalizumab for chronic rhinosinusitis with nasal polyps (CRSwNP) and to identify evidence gaps that will guide future research on omalizumab for CRSwNP.DesignSystematic review and meta-analysis.Data sourcesA comprehensive search was performed in PubMed, Embase, Web of Science and the Cochrane Library on 13 October 2020.Eligibility criteriaRandomised controlled trials (RCTs) comparing omalizumab with placebo, given for at least 16 weeks in adult patients with CRSwNP.Data extraction and synthesisTwo independent authors screened search results, extracted data and assessed studies using the Cochrane risk of bias tool. Data were pooled using the inverse-variance method and expressed as mean differences (MDs) with 95% CIs. Heterogeneity was assessed by the χ2 test and the I2 statistic.ResultsA total of four RCTs involving 303 participants were identified. When comparing omalizumab to placebo, there was a significant difference in Nasal Polyps Score (MD=−1.20; 95% CI −1.48 to −0.92), Nasal Congestion Score (MD=−0.67; 95% CI −0.86 to −0.48), Sino-Nasal Outcome Test-22 (MD=−15.62; 95% CI −19.79 to −11.45), Total Nasal Symptom Score (MD=−1.84; 95% CI −2.43 to −1.25) and reduced need for surgery (risk ratio (RR)=5.61; 95% CI 1.99 to 15.81). Furthermore, there was no difference in the risk of serious adverse events ((RR=1.40; 95% CI 0.29 to 6.80), adverse events (RR=0.83; 95% CI 0.60 to 1.15) and rescue systemic corticosteroid (RR=0.52; 95% CI 0.17 to 1.61).ConclusionsThis was the first meta-analysis that identified omalizumab significantly improved endoscopic, clinical and patient-reported outcomes in adults with moderate to severe CRSwNP and it was safe and well tolerated.PROSPERO registration numberCRD42020207639.

Background: Postherpetic neuralgia (PHN) is one of the most common complications of herpes zoster (HZ), and there is still a lack of effective therapies. An increasing number of studies have found that compared to traditional therapy, moxibustion treatment is beneficial for the treatment of PHN, although current evidence remains inconclusive. This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of moxibustion for PHN.Methods: We conducted a broad literature review of a range of databases from inception to December 2020, including the Cochrane Library, PubMed, EMBASE, Web of Science, Clinical Trails, China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals (VIP), China Biomedical Network Information, and Wanfang databases. We included RCTs that compared moxibustion to pharmacological therapies, herbal medicine, or no treatment for treating PHN. The main outcome measure was efficacy rate and Visual Analog Scale (VAS); the secondary outcome measure was adverse events. Data accumulation and synthesis included meta-analysis, publication bias, sensitivity analysis, risk-of-bias assessment, and adverse events.Results: We included 13 RCTs involving 798 patients. Compared with the controls (pharmacological therapies, herbal medicine, or no treatment), moxibustion achieved a significantly higher efficacy rate (odds ratio [OR]: 3.65; 95% [confidence interval]: [2.32, 5.72]; P < 0.00001). Subgroup analysis of the distinct moxibustion modalities showed that both Zhuang medicine medicated thread and thunder-fire moxibustions obtained higher clinical efficacy than the control group. Compared with the controls, moxibustion resulted in significantly lower scores on the VAS (Weighted Mean Difference (MD) = −1.79; 95% CI: [−2.26, −1.33]; P < 0.00001). However, there was no significant difference in terms of safety between moxibustion and the controls (OR = 0.33; 95% CI [0.06, 1.77]; P = 0.19).Conclusion: Due to the lack of methodological quality as well as the significant heterogeneity of the included studies, it remains difficult to draw a firm conclusion on the efficacy and safety of moxibustion for the treatment of PHN. Future high-quality studies are urgently needed.

Background and Objective: Myasthenia gravis (MG) is an autoimmune neuromuscular disease. Nearly 10–30% of patients with MG are refractory to conventional therapy. Rituximab (RTX), a monoclonal antibody targeting CD20, is increasingly used in autoimmune disorders. We performed a systematic review and meta-analysis to evaluate the effectiveness and safety of RTX for refractory MG.Methods: Studies published between January 1, 2000 and January 17, 2021 were searched in PubMed, EMBASE, Cochrane Library, and ClincalTrails.gov. Primary outcomes included proportion of patients achieving minimal manifestation status (MMS) or better and quantitative MG (QMG) score change from baseline. Secondary outcomes were glucocorticoids (GC) doses change from baseline and proportion of patients discontinuing oral immunosuppressants.Results: A total of 24 studies involving 417 patients were included in the meta-analysis. An overall 64% (95% confidence interval, 49–77%) of patients achieved MMS or better. The estimated reduction of QMG score was 1.55 (95% confidence interval, 0.88–2.22). The mean reduction of GC doses was 1.46 (95% confidence interval, 1.10–1.82). The proportion of patients discontinuing oral immunosuppressants was 81% (95% confidence interval, 66–93%). Subgroup analyses showed that the proportion of patients achieving MMS or better and discontinuing oral immunosuppressants was higher in MuSK-MG group than those in AChR-MG group. Improvement was more pronounced in patients with mild to moderate MG compared to those with severe MG. Moreover, the efficacy appeared to be independent of the dose of RTX. 19.6% of patients experienced adverse events, most of which were mild to moderate. Only one patient developed progressive multifocal leukoencephalopathy.Conclusions: RTX can alleviate the symptom of weakness, decrease QMG score and reduce the doses of steroids and non-steroid immunosuppressive agents in refractory MG. It is well-tolerated with few severe adverse events. Randomized controlled trials are urgently needed to study the efficacy of RTX in treating refractory MG and to identify the characteristics of patients who might respond well to RTX.

Abstract Background Frail older adults are commonly prescribed antidepressants. Yet, there is little evidence to determine the efficacy and safety of antidepressants to treat depression with concomitant frailty. To better understand this issue, we examined the efficacy and safety of second-generation antidepressants for the treatment of older adults with depression and then considered implications for frailty. Methods Due to the absence of therapeutic studies of frail older adults with depression, we conducted a systematic review and meta-analysis of double-blind, randomized controlled trials that compared antidepressants versus placebo for adults with depression, age 65 years or older. We searched PubMed/MEDLINE, Cochrane Library, reference lists from meta-analyses/studies, hand searches of publication lists, and related articles on PubMed. Outcomes included rates of response, remission, and adverse events. After evaluating the data, we applied a frailty-informed framework to consider how the evidence could be applied to frailty. Results Nine trials were included in the meta-analysis (n = 2704). Subjects had moderate to severe depression. For older adults with depression, there was no statistically significant difference in response or remission to second-generation antidepressants compared to placebo. Response occurred in 45.3% of subjects receiving an antidepressant compared to 40.5% receiving placebo (RR 1.15, 95% CI: 0.96 – 1.37, p = 0.12, I2 = 71%). Remission occurred in 33.1% with antidepressant versus 31.3% with placebo (RR 1.10, 95% CI: 0.92 – 1.31, p = 0.30, I2 = 56%) (Figure 2 and 3). There were more withdrawals due to adverse events with antidepressants, 13% versus 5.8% (RR 2.30, 95% CI: 1.45–3.63; p < 0.001; I2 = 61%; NNH 14, 95% CI:10–28). Implications for frailty Subjects in the meta-analysis did not have obvious characteristics of frailty. Using framework questions to consider the implications of frailty, we hypothesize that, like older adults, frail individuals with depression may not respond to antidepressants. Further, observational studies suggest that those who are frail may be less responsive to antidepressants compared to the non-frail. Given the vulnerability of frailty, adverse events may be more burdensome. Conclusions Second-generation antidepressants have uncertain benefit for older adults with depression and cause more adverse events compared to placebo. Until further research clarifies benefit, careful consideration of antidepressant prescribing with frailty is warranted.

Abstract BackgroundNephrotic syndrome (NS) is one of the most common childhood renal disorders globally, with an incidence of 2 to 7 cases per 100,000 children. A characteristic feature is massive proteinuria which may rapidly progress to end stage kidney failure, if uncontrolled. Most of the cases in children are steroid sensitive but associated with frequent relapses. Levamisole, a cheap antihelminthic has been used as steroid sparing agent in steroid sensitive NS (SSNS). This study assesses the efficacy and safety of Levamisole in African children with idiopathic nephrotic syndrome.MethodsWe will conduct a systematic review and meta-analysis of all Randomised controlled trials which reported African children with Idiopathic nephrotic syndrome who were on Levamisole compared to other drugs. Ten databases including PubMed, African Journals Online, Google Scholar, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Cochrane Library, Web of Science, Scopus, Clinicaltrial.gov and Research Gate will be searched using a search strategy. The search will have no time restrictions, but studies must have been conducted among African children residing in Africa and are retrievable in the English Language. Studies will be selected based on inclusion and exclusion criteria by two independent reviewers without blinding. The study quality will be assessed using the Pedro scale and risk of bias evaluated using the Cochrane Risk of Bias tool. Eligible screened studies will be inlcuded for meta-analysis using the CMA Software. Statistical, clinical and methodological heterogeneity will be tested. Subgroup analyses and meta-regression will be performed on rate of relapses, adverse event and drug dose.DiscussionThe primary outcome will be the proportion of children with remissions and or relapses within 6 -12 months post initiation of levamisole or comparators with effect size being the relative risk. Safety of Levamisole will be measured using reported adverse events. Moderating effects of age, gender, duration of illness, and dosage of Levamisole on the duration of remission, frequency of relapses and adverse events will be examined.Systematic Review RegistrationThis protocol has been registered in PROSPERO, with registration number CRD42020213327.

Background: The aim of this systematic review and meta-analysis was to investigate the efficacy and safety of remimazolam in clinical endoscopic procedure sedation.Methods: The authors searched the databases of PubMed, Embase, and Cochrane Library for studies published until January 2, 2021, that reported remimazolam sedation for endoscopic procedures. The sedative efficiency and the incidence of adverse events were assessed as outcomes. Cochrane Review Manager Software 5.3 was used to perform the statistical analyses.Results: Seven relevant studies involving a total of 1,996 patients were identified. We conducted a meta-analysis of the different controls used in the studies, that is, the placebo, midazolam, and propofol. The results demonstrated that remimazolam had a strong sedative effect, and its sedative efficiency was significantly higher than that of placebo [OR = 0.01, 95% CI: (0.00, 0.10), I2 = 30%, p &lt;0.00001]. The sedative efficiency of remimazolam was significantly higher than that of midazolam [OR = 0.12, 95% CI: (0.08, 0.21), I2 = 0%, p &lt; 0.00001] but lesser than that of propofol [OR = 12.22, 95% CI: (1.58, 94.47), I2 = 0%, p = 0.02]. Regarding the adverse events, remimazolam is associated with a lower incidence of hypotension than placebo and midazolam. Similarly, remimazolam was associated with a lower incidence of hypotension and hypoxemia than propofol.Conclusions: Remimazolam is a safe and effective sedative for patients undergoing endoscopic procedures. The sedative efficiency of remimazolam was significantly higher than that of midazolam but slightly lower than that of propofol. However, the respiration and circulation inhibitory effects of remimazolam were weaker than those of midazolam and propofol.

Background and Objective: We performed this systematic review and meta-analysis to assess the efficacy and safety of antigen-specific immunotherapy (Belagenpumatucel-L, MAGE-A3, L-BLP25, and TG4010) in the treatment of patients with non-small-cell lung cancer (NSCLC). </P><P> Methods: A comprehensive literature search on PubMed, Embase, and Web of Science was conducted. Eligible studies were clinical trials of patients with NSCLC who received the antigenspecific immunotherapy. Pooled hazard ratios (HRs) with 95% confidence intervals (95%CIs) were calculated for overall survival (OS), progression-free survival (PFS). Pooled risk ratios (RRs) were calculated for overall response rate (ORR) and the incidence of adverse events. </P><P> Results: In total, six randomized controlled trials (RCTs) with 4,806 patients were included. Pooled results showed that, antigen-specific immunotherapy did not significantly prolong OS (HR=0.92, 95%CI: 0.83, 1.01; P=0.087) and PFS (HR=0.93, 95%CI: 0.85, 1.01; P=0.088), but improved ORR (RR=1.72, 95%CI: 1.11, 2.68; P=0.016). Subgroup analysis based on treatment agents showed that, tecemotide was associated with a significant improvement in OS (HR=0.85, 95%CI: 0.74, 0.99; P=0.03) and PFS (HR=0.70, 95%CI: 0.49, 0.99, P=0.044); TG4010 was associated with an improvement in PFS (HR=0.87, 95%CI: 0.75, 1.00, P=0.058). In addition, NSCLC patients who were treated with antigen-specific immunotherapy exhibited a significantly higher incidence of adverse events than those treated with other treatments (RR=1.11, 95%CI: 1.00, 1.24; P=0.046). </P><P> Conclusion: Our study demonstrated the clinical survival benefits of tecemotide and TG4010 in the treatment of NSCLC. However, these evidence might be limited by potential biases. Therefore, further well-conducted, large-scale RCTs are needed to verify our findings.

ObjectivesDespite remarkable advances in the treatment of oesophageal cancer (OC), the role of antiepidermal growth factor receptor (anti-EGFR) agents in treating OC remains controversial. Herein, a systematic review and meta-analysis were conducted to elucidate the efficacy and safety of anti-EGFR agents in patients with OC.DesignMeta-analysis of randomised controlled trials (RCTs) identified by searching the PubMed, Embase, Web of Science, ClinicalTrials.gov, Cochrane Library, Chinese Biology Medicine, China National Knowledge Infrastructure and Wanfang Data Knowledge Service Platform databases from inception to December 2019. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.SettingRCTs from any country and healthcare setting.ParticipantsPatients with OC.InterventionsCombination therapy with anti-EGFR agents and conventional treatments versus conventional treatments alone in patients with OC.Primary and secondary outcome measuresOverall survival (OS) and progression-free survival (PFS) were primary outcome measures, and objective response rate (ORR), disease control rate (DCR) and treatment toxicities were secondary outcome measures.ResultsIn total, 25 RCTs comprising 3406 patients with OC were included. Overall, anti-EGFR treatment significantly improved the OS (HR: 0.81, 95% CI 0.74 to 0.89, p<0.00001), ORR (relative risk (RR): 1.33, 95% CI 1.16 to 1.52, p<0.0001) and DCR (RR: 1.22, 95% CI 1.11 to 1.34, p<0.0001) but not PFS (HR: 0.91, 95% CI 0.76 to 1.08, p=0.26). Anti-EGFR treatment was significantly associated with higher incidences of myelosuppression, diarrhoea, acne-like rash and hypomagnesaemia.ConclusionsOverall, anti-EGFR agents have positive effects on OS, the ORR and DCR in OC. However, considering the high incidence of adverse effects, such as myelosuppression, diarrhoea, acne-like rashes and hypomagnesaemia, careful monitoring of patients with OC is recommended during anti-EGFR treatment.Trial registration numberCRD42020169230.

ABSTRACTPurposeof Review: To investigate the efficacy and safety of CVT-301 for motor fluctuation in Parkinson’s disease (PD).Recent Findings:This study demonstrated that the CVT-301 group had a higher proportion of patients achieving an ON state than the placebo group (OR=2.68; 95% CI: 1.86-3.86; p<0.00001). Moreover, CVT-301 had also shown to improve motor function by UPDRS-III score (SMD=3.83; 95% CI: 2.44-5.23; p<0.00001) and promote an overall improvement of PD by PGIC self-rating (OR=2.95; 95% CI: 1.78-4.9; p<0.00001). The most common adverse events encountered were respiratory symptoms (OR=12.18; 95% CI: 5.01-29.62; p<0.00001) and nausea (OR=3.95; 95% CI: 1.01-15.41; p=0.05).Summary:CVT-301 had the potential to be an alternative or even a preferred treatment for motor fluctuation in PD patients.

Introduction Maternal depression (MD), is an overarching term for depression affecting pregnant women and mothers for up to 12 months postpartum. Because MD may have chronic and long-lasting effects, it is an important public health concern. The extent to which telemedicine may be an effective way to provide services to sufferers of MD is unknown, therefore, this review aimed to assess the available evidence. Methods We conducted a search of The Cochrane Library, PubMed/MEDLINE, PsycINFO, and EMBASE for relevant randomised controlled trials published between 2000 and 2018; we then conducted a systematic review and meta-analysis. Results We identified 10 studies for inclusion. Therapeutic strategies involved cognitive behavioural therapy (CBT), behavioural activation and other psychoeducation. Eight trials reported significant improvement in depression scores post-intervention; four studies that conducted post-intervention follow-up found that these improvements continued. However, high attrition rates and lack of blinding were common problems. Discussion This review found limited evidence supporting the delivery of CBT for the treatment of MD and anxiety using telemedicine. However, most of the evidence only studied improvements in postpartum depression, indicating that use of telemedicine to provide MD intervention is still small and an under-researched area.
