Preadmission Statin Therapy Is Associated with a Lower Incidence of Acute Kidney Injury in Critically Ill Patients: A Retrospective Observational Study. J Clin Med 2018; 8:jcm8010025. [PMID: 30585236 PMCID: PMC6351906 DOI: 10.3390/jcm8010025] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Revised: 12/17/2018] [Accepted: 12/20/2018] [Indexed: 12/24/2022] Open
Abstract
This study aimed to investigate the association between preadmission statin use and acute kidney injury (AKI) incidence among critically ill patients who needed admission to the intensive care unit (ICU) for medical care. Medical records of patients admitted to the ICU were reviewed. Patients who continuously took statin for >1 month prior to ICU admission were defined as statin users. We investigated whether preadmission statin use was associated with AKI incidence within 72 h after ICU admission and whether the association differs according to preadmission estimated glomerular filtration rate (eGFR; in mL min−1 1.73 m−2). Among 21,236 patients examined, 5756 (27.1%) were preadmission statin users and 15,480 (72.9%) were non-statin users. Total AKI incidence within 72 h after ICU admission was 31% lower in preadmission statin users than in non-statin users [odds ratio (OR), 0.69; 95% confidence interval (CI), 0.61–0.79; p < 0.001]. This association was insignificant among individuals with eGFR <30 mL min−1 1.73 m−2 (p > 0.05). Our results suggested that preadmission statin therapy is associated with a lower incidence of AKI among critically ill patients; however, this effect might not be applicable for patients with eGFR <30 mL min−1 1.73 m−2.

Lee JGH, Genga KR, Pisitsak C, Boyd JH, Leung AKK, Russell JA, Walley KR. Survival benefit of a low ratio of visceral to subcutaneous adipose tissue depends on LDL clearance versus production in sepsis. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2018; 22:58. [PMID: 29510719 PMCID: PMC5840798 DOI: 10.1186/s13054-018-1985-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/21/2017] [Accepted: 02/08/2018] [Indexed: 12/25/2022]
Abstract
Background Patients with sepsis with a high ratio of visceral adipose tissue (VAT) to subcutaneous adipose tissue (SAT) have increased mortality. Our goal was to investigate the mechanism of this effect, noting that low LDL levels are also associated with increased sepsis mortality. Accordingly we tested for association between VAT/SAT, low-density lipoprotein (LDL) levels, and mortality. Then we examined the effect of statin treatment, which decreases LDL production, and the effect of PCSK9 genotype, which increases LDL clearance. Methods We performed retrospective analysis of a cohort of patients with sepsis from a tertiary care adult intensive care unit in Vancouver, Canada, who underwent abdominal computed tomography (CT) (n = 75) for clinical reasons. We compared LDL levels in patients with sepsis according to high versus low VAT/SAT and 90-day survival. We next examined the effects of statin therapy and PCSK9 loss-of-function genotype on survival. Results Patients with a low VAT/SAT had increased 90-day survival and were relatively protected against low LDL levels in sepsis compared to high VAT/SAT. Statin treatment abrogated the beneficial effects of low VAT/SAT; eliminating the difference in LDL levels and survival between patients with low and high VAT/SAT. PSCK9 loss-of-function genotype similarly eliminated the increased LDL levels in low VAT/SAT patients but, in contrast, increased the survival advantage of low VAT/SAT compared to high VAT/SAT. Conclusions Low LDL levels per se are not simply associated with decreased sepsis survival because lowering LDL levels by inhibiting LDL production (statin treatment) is associated with adverse outcomes, while increased LDL clearance (PCSK9 loss-of-function genotype) is associated with improved outcomes in patients with low VAT/SAT.

Abstract
Background: Studies have evaluated the use of statins in sepsis; however, no human studies have explored their effect on vasopressor requirements in septic shock. Objective: The primary objective was to determine the effect of prehospital statin continuation on duration of vasopressor therapy in patients with septic shock. Secondary objectives included maximum and average vasopressor dose and in-hospital mortality. Methods: This was a retrospective, institutional board–approved, observational cohort study in a community teaching hospital; 119 adult intensive care unit (ICU) patients with an ICD-9 code for septic shock and prehospital statin therapy were evaluated. Multivariate analyses were performed to address confounders. Results: Of the 1229 patients screened, 119 (10%) met inclusion criteria; 73 patients (61%) had a statin continued within 24 hours of ICU admission. Crude analysis demonstrated no difference in vasopressor duration in the statin versus no statin group (3.3 vs 4.8 days; P = 0.21). There was no difference in either maximum (17.9 ± 16.1 vs 23.8 ± 21.7 µg/min norepinephrine equivalents [NEQs]; P = 0.1) or average vasopressor dose (9.5 ± 8.4 vs 12.1 ± 11.5 µg/min NEQ; P = 0.17). There was a decrease in mortality in the statin patients (43% vs 67 %; P = 0.05). On adjustment for potential confounders, there was no difference in any outcome, with a persistent trend toward lower mortality in the statin group. Conclusion: Continuation of prehospital statin therapy decreased neither duration nor dose of vasopressors in patients with septic shock but yielded a trend toward decreased mortality.

Abstract
BACKGROUND The pleiotropic effects of statins have prompted considerable research in fields other than cardiovascular disease. We reviewed the literature aiming to summarize and critically evaluate the current evidence about the potential use of statins in sepsis. MATERIALS AND METHODS We searched the Pubmed, SciELO, and Cochrane electronic databases from inception through November 1, 2013, for randomized controlled trials (RCTs) and cohort studies that examined the association between statin use (upon hospital admission or previous users) and the risk or outcome of sepsis. Data on study characteristics, measurement of statin use, and outcomes (adjusted for potential confounders) were extracted. We structured our review according to the Principles of Reporting in Systematic Reviews and Meta-Analysis criteria. Quality assessment of cohort studies was performed using the Ottawa-Newcastle Scale. RESULTS Twenty-three cohort studies and 5 RCTs were eligible, comprising 42 549 statin users and 54 201 non-statin users, from 1995 to 2013. The populations included varied from patients admitted to general wards or intensive care units with bacterial infections, community-acquired pneumonia, ventilator-associated pneumonia, bacteremia, or sepsis, to outpatients with chronic kidney disease or established cardiovascular disease. Overall, 16 studies reported a benefit from statin use in morbidity or mortality outcomes (range of adjusted odds ratio, 0.06-0.62; α = 0.05). The remaining 12 studies found no protective effect associated with statin use upon hospital admission or previous users. Among the 5 RCTs, none demonstrated a reduction in mortality. CONCLUSION There is insufficient evidence to support the use of statins in patients with sepsis, as the existing studies failed to prove a consistent mortality benefit. More clinical trials are warranted to provide more conclusive knowledge and ultimately change clinical practice.

Abstract
INTRODUCTION Although statins have been shown to have cholesterol-lowering effects, their pleiotropic benefits on sepsis remain a matter of debate. In addition, the influence of statin potency on sepsis-related mortality has never been explored. The aim of our study was to determine the sepsis outcomes of low- and high-potency statin users and non-users. METHODS This nationwide, population-based, propensity score-matched analysis used data from the linked administrative databases of Taiwan's National Health Insurance program. Patients were hospitalized for sepsis between 2000 and 2010. All-cause mortality and major adverse consequences of sepsis, such as in-hospital death, intensive care unit admission, shock events, and the use of mechanical ventilation, were assessed. Patients were divided into high-potency statin users (at least 10 mg rosuvastatin, at least 20 mg atorvastatin, or at least 40 mg simvastatin), low-potency statin users (all other statin treatments), and non-users. RESULTS A propensity score-matched cohort of 27,792 statin users and 27,792 non-users was included. Of 27,792 statin users, 9,785 (35.2 %) were treated with high-potency statins and 18,007 (64.8 %) were treated with low-potency statins. The 1-year mortality risk was significantly lower among both low-potency [adjusted hazard ratio (aHR) 0.89, 95 % confidence interval (CI) 0.85-0.93] and high-potency (aHR 0.80, 95 % CI 0.75-0.86) statin users compared with non-users. The risks of mortality and adverse consequences of sepsis were lower among high-potency than among low-potency statin users. CONCLUSIONS High-potency statin use is associated with a lower risk of sepsis-related mortality compared with low-potency statin use.

Abstract
Sepsis is a complex disease with typically poor outcomes. While the onset of sepsis is typically infectious, the detrimental consequences follow pathogen toxin release that produces activation of numerous cytokines and a pro-inflammatory response. These same cytokines also stimulate activation of coagulation and inhibit natural fibrinolysis. Despite decades of research targeted against these pathways the development of sepsis and mortality in patients with sepsis remains high. While statins were developed for reducing cholesterol in patients with atherosclerotic disease, we now know they have a number of other properties which may be helpful in the prevention and treatment of sepsis. Statins have demonstrated the ability to reduce a number of pro-inflammatory cytokines known to be detrimental in the development and progression of sepsis. Statins have also demonstrated the ability to limit the coagulation response and promote fibrinolysis in the setting of sepsis. Based on these encouraging pharmacologic properties of statins a number of trials have been conducted evaluating the impact of statins on the prevention and treatment of sepsis. Most of the trials to date have been retrospective cohort trials, with very few prospective randomized trials. While some trials fail to demonstrate a benefit of statins, most trials suggest a reduction in the development of sepsis and/or other important sepsis related outcomes. While the laboratory and early clinical experience with statins are encouraging, randomized controlled trials will be need to fully define the role of statins in the prevention and treatment of sepsis.
