Creatinine Change on Vasoconstrictors as Mortality Surrogate in Hepatorenal Syndrome: Systematic Review & Meta-Analysis.

ABSTRACT:

Background and aims

Hepatorenal syndrome is a severe complication of cirrhosis and associates with significant mortality. Vasoconstrictor medications improve renal function in patients with hepatorenal syndrome. However, it is unclear to what extent changes in serum creatinine during treatment may act as a surrogate for changes in mortality. We have performed a meta-analysis of randomized trials of vasoconstrictors assessing the association between changes in serum creatinine, taken as a continuous variable, and mortality, both while on treatment and during the follow-up period for survivors.

Methods

The electronic databases of PubMed, Web of Science and Embase were searched for randomized trials evaluating the efficacy of vasoconstrictor therapy for treatment of HRS type 1 or 2. The relative risk (RR) for mortality was calculated against delta creatinine. The proportion of treatment effect explained (PTE) was calculated for delta creatinine.

Results

Seven trials enrolling 345 patients were included. The correlation between delta creatinine and ln (RR) was moderately good (R2 = 0.61). The intercept and parameter estimate indicated a fall in creatinine while on treatment of 1 mg/dL resulted in a 27% reduction in RR for mortality compared to the control arm. In patients surviving the treatment period, a fall in creatinine while on treatment of 1 mg/dL resulted in a 16% reduction in RR for post-treatment mortality during follow-up. The PTE of delta creatinine for overall mortality was 0.91 and 0.26 for post-treatment mortality.

Conclusions

Changes in serum creatinine in response to vasoconstrictor therapy appear to be a valid surrogate for mortality, even in the period following the completion of treatment.

Project description:ObjectivesThere is a lack of evidence about the use of local anaesthetics (LAs) in patients with cardiovascular diseases (CVD) in dental procedures. Thus, this study evaluated the safety of using LA with vasoconstrictor to determine the risk of cardiovascular events in patients with CVD.DesignSystematic review and meta-analysis.MethodsWe have searched in Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (via Ovid), EMBASE (via Ovid), Healthstar (via Ovid), CINAHL, Web of Science and ClinicalTrials.gov for randomised controlled trials (RCTs) up to January 2020. We have included RCTs involving adults with CVD within two groups: intervention group with LA with vasoconstrictor and control group with LA without vasoconstrictor. The primary outcomes assessed were death, mortality by a specific cause, stroke, acute myocardial infarction, hospitalisation, pain, bleeding and arrhythmias. The secondary outcomes were ST segment depression, anxiety, adverse effects and changes in haemodynamic parameters. The data were pooled using random effects meta-analyses and the confidence in the estimates was verified using the Grading of Recommendations Assessment, Development and Evaluation (GRADE).ResultsTen RCTs (n=478 participants) were included. Most of them had a high risk of bias. There were more cases of pain and bleeding in groups without vasoconstrictor. Meta-analysis demonstrated a decrease in the systolic blood pressure with the use of LA with vasoconstrictor (standard mean difference -0.95, 95% CI -1.35 to -0.55) after procedure. Overall, for the other outcomes assessed there was no statistical difference. The quality of evidence was considered low according to the GRADE profile.ConclusionsThe results suggest that the use of LA with vasoconstrictors (epinephrine in low doses) is safe in patients with some types of CVD. However, the low quality of evidence demonstrated that literature needs further studies in order to confirm these results.Protocol registrationPROSPERO (CRD42016045421).

Project description:INTRODUCTION:The use of vasoconstrictors combined with local anaesthetics (LAs) in dentistry for patients with cardiovascular disease (CVD) is still controversial in the scientific literature. It raises concerns regarding the possibility of transient episodes, triggering negative cardiovascular outcomes. METHOD/DESIGN:Trials eligible for our systematic review will enrol patients with CVD who have undergone dental treatments carried out with the use of LAs by comparing two arms: LAs with vasoconstrictors and LAs without vasoconstrictors. The research will be conducted in the electronic databases, namely Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Healthstar (via Ovid), Cumulative Index to Nursing and Allied Health Literature and Web of Science, from their inception to December 2017, without any restrictions in terms of language and status of publication. A team of reviewers will independently assess titles, abstracts and complete text to determine eligibility. For eligible studies, the same reviewers will perform data extraction and evaluate the risk of bias in the selected articles. The selected outcomes comprise death, mortality by a specific cause, stroke, acute myocardial infarction, hospitalisation, pain, bleeding, arrhythmias, ischaemic episodes, anxiety, adverse effects, changes in blood pressure, changes in heart rate, anxiety and results obtained via oximetry. Whenever possible, we will conduct a meta-analysis to establish the effects of LAs with and without vasoconstrictors in the patients with CVD, and the overall quality of evidence for each outcome will be determined using the Grading of Recommendations Assessment, Development and Evaluation classification system. ETHICS AND DISSEMINATION:Ethics committee approval was not necessary because this is a protocol of systematic review. This systematic review will be submitted for presentation at conferences and for publication in a peer-reviewed journal. Our review will assess the risks of cardiovascular events when using LAs with and without vasoconstrictors in patients with CVD, focusing on important clinical outcomes.
