Previous studies have reported that statin or ezetimibe therapy has an anti-inflammatory effect. However, the results of individual studies on the effect of statin therapy in combination with ezetimibe on C-reactive protein (CRP) and high-sensitivity CRP (hs-CRP) levels have not been clear. Therefore, the present systematic review and meta-analysis were conducted on randomized clinical trials (RCTs) to evaluate the effect of statin therapy in combination with ezetimibe on CRP and hs-CRP levels.
Methods
A literature search was carried out on the MEDLINE, SciVerse Scopus, and Clarivate Analytics Web of Science databases up to February 2022 to find eligible studies. The pooled effect sizes were considered for weighted mean difference (WMD) and 95% confidence intervals (CI) for CRP and hs-CRP, and it was also determined as standardized weighted mean difference (SMD) for overall CRP. For all variables, a random-effects model was used.
Results
Of the 57 studies included in the systematic review, 53 were used for meta-analysis. Statin therapy in combination with ezetimibe significantly reduced the serum levels of hs-CRP (WMD ??0.2 mg/l; 95% CI ??0.4, ??0.1, P???0.001) and overall CRP (SMD ??0.16 mg/l; 95% CI ??0.2, ??0.07, P???0.001). Nevertheless, CRP levels were not significantly changed by combination therapy. A significant association was observed between the serum low-density lipoprotein cholesterol (LDL-C) changes and hs-CRP levels, which can justify the source of heterogeneity.
Conclusions
The current study showed that statin therapy in combination with ezetimibe could be effective in reducing the levels of hs-CRP and overall CRP.
BackgroundDetermining prognosis in community acquired pneumonia (CAP), is very important. Many scores are introduced up to now for prediction of pneumonia prognosis like SMART-COP.ObjectiveTo evaluate validity of SMART-COP score in prognosis and severity of CAP in emergency department (ED).MethodsAll patients older than 18 years old with clinical suspicion of CAP (meeting the inclusion criteria), were enrolled in our study. In this prospective study, patients were admitted to the ED of a tertiary referral center. Hospital length of stay, rate of intensive care unit (ICU) admission, mortality rate, number of intensive respiratory or vasopressor support (IRVS) use, patients' SMART-COP scores and all demographic data were recorded. Validity of SMART-COP in the prediction of IRVS rate and its correlation with other variables were determined.ResultsIn this study, 47.6% and 52.4% of patients were females and males respectively. The mean age of patients was 68.13 ± 16.60 years old. The mean hospital length of stay was 13.49 ± 5.62 days. Of all patients entered in our study, 55 cases (38.5%) needed ICU admission, 29 cases (20.3%) were expired within 1 month and 44 cases (30.8%) needed IRVS during their treatment. SMART-COP ≥5 (high risk CAP) accurately predicted the rate of ICU admission, one-month mortality and IRVS need (p-value = 0.001).ConclusionsSMART-COP≥5 had a high sensitivity and specificity in the prediction of patients' prognosis with severe CAP in the ED. 相似文献
Multiparametric magnetic resonance imaging (mpMRI) undoubtedly affects the diagnosis and treatment of localized prostate cancer (CaP). However, clinicians need a better understanding of its accuracy and limitations in detecting individual CaP foci to optimize management.
Objective
To determine the per-lesion detection rate for CaP foci by mpMRI and identify predictors of tumor detection.
Design, setting, and participants
We carried out a retrospective analysis of a prospectively managed database correlating lesion-specific results from mpMRI co-registered with whole-mount pathology (WMP) prostatectomy specimens from June 2010 to February 2018. Participants include 588 consecutive patients with biopsy-proven CaP undergoing 3-T mpMRI before radical prostatectomy at a single tertiary institution.
Outcome measurements and statistical analysis
We measured mpMRI sensitivity in detecting individual CaP and clinically significant (any Gleason score ≥7) CaP foci and predictors of tumor detection using multivariate analysis.
Results and limitations
The final analysis included 1213 pathologically confirmed tumor foci in 588 patients with primarily intermediate- (75%) or high-risk (12%) CaP. mpMRI detected 45% of all lesions (95% confidence interval [CI] 42–47%), including 65% of clinically significant lesions (95% CI 61–69%) and nearly 80% of high-grade tumors. Some 74% and 31% of missed solitary and multifocal tumors, respectively, were clinically significant. The majority of missed lesions were small (61.1% ≤1 cm); 28.3% were between 1 and 2 cm, and 10.4% were >2 cm. mpMRI missed at least one clinically significant focus in 34% of patients overall, and in 45% of men with multifocal lesions. On multivariate analysis, smaller, low-grade, multifocal, nonindex tumors with lower prostate-specific antigen density were more likely to be missed. Limitations include selection bias in a prostatectomy cohort, lack of specificity data, an imperfect co-registration process, and uncertain clinical significance for undetected lesions.
Conclusions
mpMRI detects less than half of all and less than two-thirds of clinically significant CaP foci. The moderate per-lesion sensitivity and significant proportion of men with undetected tumor foci demonstrate the current limitations of mpMRI.
Patient summary
Magnetic resonance imaging of the prostate before surgical removal for prostate cancer finds less than half of all individual prostate cancer tumors. Large, solitary, aggressive tumors are more likely to be visualized on imaging. 相似文献
Chronic pelvic pain syndrome (CPPS) can be triggered by a various types of gynecological, gastrointestinal, urological, and musculoskeletal disorders. Recently, the role of the central nervous system has proven to be an integral part on the development of any chronic pain syndrome, including CPPS. However, owing to the complex and heterogeneous etiology and pathophysiology of CPPS, the establishment of effective therapeutic interventions remains challenging for both physicians and patients. Nonetheless, recent studies have pointed that medicinal plants and their secondary metabolites can be effectively used in CPPS therapy, besides contributing to restore the patients' quality of life and potentiate the conventional CPPS management. In this sense, this review aims to provide a careful overview on the biomedical data for the use of medicinal plants use and their secondary metabolites on CPPS management. 相似文献
The high concentrations of free fatty acids as a consequence of obesity and being overweight have become risk factors for the development of different diseases, including neurodegenerative ailments. Free fatty acids are strongly related to inflammatory events, causing cellular and tissue alterations in the brain, including cell death, deficits in neurogenesis and gliogenesis, and cognitive decline. It has been reported that people with a high body mass index have a higher risk of suffering from Alzheimer's disease. Hormones such as oestradiol not only have beneficial effects on brain tissue, but also exert some adverse effects on peripheral tissues, including the ovary and breast. For this reason, some studies have evaluated the protective effect of oestrogen receptor (ER) agonists with more specific tissue activities, such as the neuroactive steroid tibolone. Activation of ERs positively affects the expression of pro‐survival factors and cell signalling pathways, thus promoting cell survival. This review aims to discuss the relationship between lipotoxicity and the development of neurodegenerative diseases. We also elaborate on the cellular and molecular mechanisms involved in neuroprotection induced by oestrogens. 相似文献
The serine protease proprotein convertase subtilisin/kexin type 9 (PCSK9) modulates the levels of low-density lipoprotein cholesterol and cardiovascular risk. Potential risks of adverse neurological effects of intensive lipid-lowering treatment have been hypothesized, as cholesterol is a component of the central nervous system. Moreover, several observations suggest that PCSK9 might play a role in neurogenesis, neuronal migration and apoptosis. In rodents, increased expression of PCSK9 has been detected in specific areas of the central nervous system during embryonic development; also, PCSK9 modulates low-density lipoprotein receptor levels in the ischemic brain areas. Despite a putative participation of PCSK9 in nervous system physiology, the absence of PCSK9 in knockout mice or in humans with loss-of-function mutations of PCSK9 gene has not been linked to neurological alterations. In recent years, some concerns have been raised about the potential neurological side effects of cholesterol-lowering treatments and, more specifically of PCSK9 inhibitors. In this review, the evidence regarding the function of PCSK9 in neuron differentiation, apoptosis, and migration and in nervous system development and latest clinical trials evaluating the effects of PCSK9 inhibitors on neurocognitive function will be described. 相似文献
