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.
Diabetes mellitus currently affects as many as 400 million people worldwide, creating a heavy economic burden and stretching health care resources. A dysfunction of glucose homeostasis underlies the disease. Despite advances in the treatment of diabetes, many patients still suffer from complications and side effects; hence, development of more effective treatments for diabetes is still desirable. SGLT2 is the principle cotransporter involved in glucose reabsorption in the kidney. SGLT2 inhibition reduces glucose reabsorption by the kidney and ameliorates plasma glucose concentration. The interest in natural products that can be used for the inhibition of SGLT2 is growing. The flavonoid phlorizin, which can be isolated from the bark of apple trees, has been used as lead structure due to its inhibitory activity of SGLT1 and SGLT2. Some phlorizin‐derived synthetic compounds, including canagliflozin, dapagliflozin, empagliflozin, ipragliflozin, and ertugliflozin, are approved by the food and drug administration to treat type 2 diabetes mellitus (T2DM), whereas others are under clinical trials investigation. In addition, other natural product‐derived compounds have been investigated for their ability to improve blood glucose control. The present review summarizes the natural products with SGLT2 inhibitory activity, and the synthetic compounds obtained from them, and discusses their application for the treatment of diabetes. 相似文献
Phytotherapy is a source of finding new remedies for migraine. Traditional chamomile oil (chamomile extraction in sesame oil) is a formulation in Persian medicine (PM) for pain relief in migraine. An oleogel preparation of reformulated traditional chamomile oil was prepared and then standardized based on chamazulene (as a marker in essential oil) and apigenin via gas chromatography (GC) and high-performance liquid chromatography (HPLC) methods, respectively. A crossover double-blind clinical trial was performed with 100 patients. Each patient took two tubes of drug and two tubes of placebo during the study. Visual analog scale (VAS) questionnaires were filled in by the patients and scores were given, ranging from 0 to 10 (based on the severity of pain) during 24 h. Other complications like nausea, vomiting, photophobia, and phonophobia were also monitored. There was 4.48?±?0.01 μl/ml of chamazulene and 0.233 mg/g of apigenin in the preparation (by correcting the amount with extraction ratio). Thirty-eight patients in the drug-placebo and 34 patients in the placebo-drug groups (a total number of 72 patients as per protocol) completed the process in the randomized controlled trial (RCT). Adapted results from the questionnaires showed that pain, nausea, vomiting, photophobia, and phonophobia significantly (p?<?0.001) decreased by using chamomile oleogel on the patients after 30 min. Results supported the efficacy of chamomile oleogel as a pain relief in migraine without aura. 相似文献
Bacterial vaginosis (BV) is a vaginal disorder which occurs either symptomatic or asymptomatic because of an imbalance between H2O2-producing Lactobacillus and Gardnerella vaginalis in the vagina. This systematic review and meta-analysis is the first to determine the prevalence of BV in pregnant and non-pregnant women in Iran.
Methods
We used national (SID, Irandoc, Iranmedex and Magiran) and international (PubMed, Scopus, Google Scholar and ISI web of knowledge) electronic databases to systematically search and collect available studies using related keywords (up to 1 December 2017). Inclusion and exclusion criteria were defined to select eligible studies.
Results
The overall prevalence of BV among Iranian women was 18.9% (95% CI 14–25). Gardnerella vaginalis was the most prevalent isolated bacteria. The prevalence of BV in non-pregnant women was 28% (95% CI 15.1–45.9) which was higher compared with pregnant women who had a prevalence of 16.5% (95% CI 12.5–21.6).
Conclusion
The present review revealed a high prevalence of BV in non-pregnant women. Given that BV is associated with a series of reproductive complications such as infertility, taking preventive measures such as awareness of patients as well as monitoring and controlling of syndrome are essential.
IntroductionThe aim of the study was to study a nanoliposomal anti-PCSK9 vaccine as a novel approach for cholesterol lowering via PCSK9 inhibition.Material and methodsAn immunogenic peptide construct termed immunogenic fused PCSK9-tetanus (IFPT) was displayed on the surface of liposome nanoparticles (L-IFPT) and mixed into alum adjuvant (L-IFPTA+). The manufactured vaccine formulations IFPT, L-IFPT, L-IFPTA+, IFPTA+, and free nanoliposomes were subcutaneously injected four times with bi-weekly intervals in C57BL/6 mice on a severe atherogenic protocol.ResultsAmong the formulations, L-IFPTA+ vaccine was found to elicit the highest IgG response against PCSK9 peptide. The induced PCSK9 antibodies inhibited PCSK9-LDLR interaction through binding to PCSK9 in vaccinated mice. Liver low-density lipoprotein receptor (LDLR) protein was increased in vaccinated mice. L-IFPTA+, L-IFPT and IFPTA+ vaccines reduced total cholesterol by up to –38.13 ±3.8% (p = 0.006), –23 ±4.1% (p = 0.027) and –19.12 ±3% (p = 0.038), and low-density lipoprotein cholesterol (LDL-C) by up to –57 ±7.7% (p = 0.0003), –41.67 ±4.2% (p = 0.03) and –36.11 ±5% (p = 0.02) in hypercholesterolemic mice, respectively, versus control mice after 8 weeks. Long-term assessment indicated that the vaccine formulations could stimulate a long-lasting humoral immune response against PCSK9 peptide, which was associated with a marked reduction of total cholesterol in L-IFPTA+, L-IFPT and IFPTA+ vaccine groups by up to –82.5 ±7.3% (p = 0.002), –70.54 ±6.2% (p = 0.013) and –72.02 ±8.7% (p = 0.004), respectively, and LDL-C by up to –88.14 ±5.6% (p = 0.002), –55.92 ±8.3% (p = 0.003) and 54.81 ±9.3% (p = 0.003), respectively, versus the pre-vaccination time point adjusted to the control group. Anti-inflammatory Th2 cells and IL-4 cytokine were considerably increased in splenocytes of vaccinated mice.ConclusionsL-IFPTA+ vaccine can induce long-lasting, functional and safe PCSK9-specific antibodies in hypercholesterolemic C57BL/6 mice, providing a long-term protective impact on dyslipidemia and atherosclerosis. 相似文献
