Abstract Background The use of ultrashort-acting β1-blockers recently has attracted attention in septic patients with non-compensatory tachycardia. We summarized the metabolic and hemodynamic effects and the clinical evidence of ultrashort-acting β1-blockers. Main body A recent meta-analysis showed that ultrashort-acting β1-blockers reduced the mortality in septic patients with persistent tachycardia. However, its mechanism to improve mortality is not fully understood yet. We often use lactate as a marker of oxygen delivery, but an impaired oxygen use rather than reduced oxygen delivery has been recently proposed as a more reasonable explanation of hyperlactatemia in patients with sepsis, leading to a question of whether β1-blockers affect metabolic systems. While the stimulation of the β2-receptor accelerates glycolysis and lactate production, the role of β1-blocker in lactate production remains unclear and studies investigating the role of β1-blockers in lactate kinetics are warranted. A meta-analysis also reported that ultrashort-acting β1-blockers increased stroke volume index, while it reduced heart rate, resulting in unchanged cardiac index, mean arterial pressure, and norepinephrine requirement at 24 h, leading to an improvement of cardiovascular efficiency. On the other hand, a recent study reported that heart rate reduction using fast esmolol titration in the very early phase of septic shock caused hemodynamic instability, suggesting that ultrashort-acting β1-blockers should be started only after completing initial resuscitation. While many clinicians still do not feel comfortable controlling sinus tachycardia, one randomized controlled trial in which the majority had sinus tachycardia suggested the mortality benefit of ultrashort-acting β1-blockers. Therefore, it still deems to be reasonable to control sinus tachycardia with ultrashort-acting β1-blockers after completing initial resuscitation. Conclusion Accumulating evidence is supporting the use of ultrashort-acting β1-blockers while larger randomized controlled trials to clarify the effect of ultrashort-acting β1-blockers are still warranted.

Sepsis And Septic Shock

Abstract Background Sepsis affects millions of people each year, and brings substantial health and economic burden to the global. Esmolol may have the potential in the treatment of sepsis and septic shock in adults. However, current evidence remains controversial. Methods We systematically searched PubMed, EMBASE and the Cochrane Central Register of Controlled Trials from their inception to September 19, 2020 for randomized controlled trials (RCTs) evaluating the efficacy of esmolol in sepsis and septic shock in adults. A random-effects meta-analysis was performed to combine effect estimates. Two investigators independently screened articles, extracted data, and assessed the quality of included studies. Results Seven RCTs were included with a total of 463 patients with sepsis and/or septic shock. Overall, compared with standard treatment, esmolol significantly decreased 28-day mortality (risk ratio [RR] 0.68, 95% confidence interval [CI] 0.52 to 0.88), and heart rate (standardized mean difference [SMD] -1.83, 95% CI -2.95 to -0.70) and troponin I (TnI) level (SMD − 0.59, 95% CI -1.02 to -0.16) at 24 hours after treatment; no significant effect was found on the length of intensive care unit stay, mean arterial pressure, central venous pressure, central venous oxygen saturation, Stroke Volume Index, tumor necrosis factor-a, interleukin 6, White Blood Cells and PO2/FiO2. Conclusions Esmolol treatment may be safe and effective in decreasing 28-day mortality, controlling heart rate, and preventing myocardial damage, but no evidence of effect on lung injury in sepsis and septic shock after fluid resuscitation early. There were no significant adverse effects on tissue perfusion and oxygen utilization.

Abstract Objective: Current meta-analysis aims to understand the effect of oral supplementation of vitamin D on intensive care unit (ICU) requirement and mortality in hospitalized COVID-19 patients. Methods: Databases PubMed, preprint servers, and google scholar were searched from December 2019 to December 2020. Authors searched for the articles assessing role of vitamin D supplementation on COVID-19. Cochrane RevMan tool was used for quantitative assessment of the data, where heterogeneity was assessed using I2 and Q statistics and data was expressed using odds ratio with 95% confidence interval. Results: Final meta-analysis involved pooled data of 532 hospitalized patients (189 on vitamin D supplementation and 343 on usual care/placebo) of COVID-19 from three studies (Two randomized controlled trials, one retrospective case-control study). Statistically (p<0.0001) lower ICU requirement was observed in patients with vitamin D supplementation as compared to patients without supplementations (odds ratio: 0.36; 95% CI: 0.210-0.626). However, it suffered from significant heterogeneity, which reduced after sensitivity analysis. In case of mortality, vitamin D supplements has comparable findings with placebo treatment/usual care (odds ratio: 0.93; 95% CI: 0.413-2.113; p=0.87). The studies did not show any publication bias and had fair quality score. Subgroup analysis could not be performed due to limited number of studies and hence dose and duration dependent effect of vitamin D could not be evaluated. Conclusions: Although the current meta-analysis findings indicate potential role of vitamin D in improving COVID-19 severity in hospitalized patients, more robust data from randomized controlled trials are needed to substantiate its effects on mortality.

AbstractRecent concerns on increased incidence of myocardial infarction and stroke on administration of calcium and vitamin D supplements have alarmed the physicians about safety of these drugs. Although both calcium and vitamin D have been shown in the past to have beneficial effect on cardiovascular disease status through lowering of harmful lipids, these findings have been contradicted by some recent meta-analysis and randomized controlled trials that have shown no beneficial or in some cases a deteriorating effect of these supplements on lipid levels. In particular, calcium supplementation has been associated more with increased incidence of cardiovascular morbidity than vitamin D, but the convincing proof is still lacking. Here we have highlighted the results of some significant studies that might impact the prescription of these drugs.

Abstract Background Nonalcoholic fatty liver disease (NAFLD) is a kind of chronic liver disease among general population. Recent years, more and more new experiments have made the role of ursodeoxycholic acid (UDCA) become clearer. In this meta-analysis, we analyzed the efficacy of ursodeoxycholic acid (UDCA) for the treatment of nonalcoholic fatty liver disease (NAFLD). Methods We searched the Web of Science, Pubmed, Embase and Cochrane library databases for relavent studies published before March 1, 2019. We examined 134 randomized controlled trials (RCTs) that investigated the effectiveness of UDCA in NAFLD against placebo or other treatments. Next, we conducted meta-analysis by Stata(version 12.0) to examine the change among several indices: Alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), Alkaline phosphatase (AP), total bilirubin and albumin. Results Following the application of different inclusion and exclusion criteria, 9 articles with 1106 participants were finally selected. The forest plot displayed that UDCA treatment can significantly decrease the ALT levels among the NAFLD patients (SMD=0.17,95%CI [0.03 to 0.3], P=0.07). However, UDCA treatment did not significantly affect the AST, GGT, AP, total bilirubin and albumin levels. Further, the subgroup analyses suggested the significant role of UDCA treatment in different geographical regions, age group and treatment duration (P=0.003 in people from Europe, P=0.001 in people older than 50 years and P=0.008 in longer duration(>6 months)). Conclusion In this study, several indices we analyzed among 9 articles. UDCA treatment was found beneficial in lowering the ALT levels in NAFLD patients. The remaining indices like AST, GGT, AP showed non-significant changes in this analysis. This could be attributed for the insufficient number of trials because all parameters were not analyzed in each individual RCT. Therefore, future meta-analysis will be required to fully confirm and validate the efficacy of UDCA in NAFL.

The Impact

AbstractBackgroundThe COVID-19 pandemic has stimulated worldwide investigation into a myriad of potential therapeutic agents, including antivirals such as remdesivir. The first RCT reporting results on the impact of remdesivir on COVID-19 in a peer reviewed journal was the ACTT-1 trial published in November, 2020. The ACTT-1 trial showed more rapid clinical improvement and a reduced risk of 28-day mortality in patients who received remdesivir.This study is a meta-analysis of peer reviewed RCTs aims to estimate the association of remdesivir therapy compared to the usual care or placebo on all-cause mortality in hospitalized patients with COVID-19. Software based tools to accelerate the analysis process.MethodsMeta-analysis of peer reviewed RCTs comparing remdesivir to usual care or placebo. The protocol for this meta-analysis was registered and published in the PROSPERO database (CRD42021229985) on February 5, 2021.ResultsFour English language RCTs were identified, including data from 7,333 hospitalized patients worldwide using remdesivir in COVID-19 positive patients.Meta-analysis of all identified RCTs showed no difference in survival in patients who received remdesivir therapy compared to usual care or placebo. The random effects meta-analysis has a summary odd ratio is 0.89 (95% CI 0.65-1.21, p = 0.30). Considerable variability in the severity of illness is noted with the rates of IMV at the time of randomization ranging from 0% to 27%.ConclusionsThis meta-analysis of randomized controlled trials published in peer-reviewed literature by February 1, 2021 did not show reduced mortality in hospitalized patients with COVID-19 who received remdesivir. Further research is needed to clarify the role of remdesivir therapy in the management of COVID-19.
