Abstract
CONTEXT Olive leaf extract (OLE) is rich in phenolic compounds, which are known for their health benefits. Cardiovascular diseases, primarily coronary heart disease and stroke, are leading causes of mortality globally. OBJECTIVE This systematic review aimed to assess the impact of OLE on cardiometabolic risk factors in adults. The selection of studies was based on intervention and outcomes, using relevant search descriptors. DATA SOURCES The databases PubMed, EMBASE, and Web of Science were systematically searched for pertinent studies published up to August 2021. DATA EXTRACTION Only randomized clinical trials, either cross-over or parallel, involving adult individuals aged ≥18 years, were considered. Additionally, trials that had a comparative or placebo group and used pure OLEs for oral treatment were included. DATA ANALYSIS Twelve randomized clinical trials (RCTs) met the inclusion criteria. These trials had follow-up periods ranging from 2 days to 12 weeks and involved 703 patients aged 18 years-79 years. The outcomes demonstrated a positive correlation between the intervention group and glucose metabolism (4 RCTs), blood pressure (2 RCTs), lipid profile (2 RCTs), and inflammatory markers (2 RCTs). The RoB2 tool and the GRADE system were used to evaluate the risk of bias and the quality of evidence in the studies. CONCLUSIONS In the meta-analysis, fasting glycemia, as evaluated in studies using a low dose of OLE, showed a significant result favoring the control group. To obtain more consistent results, further clinical studies in humans, using similar methodologies, are required. SYSTEMATIC REVIEW REGISTRATION PROSPERO registration no. CRD42020200877.

Therapeutic Properties and Use of Extra Virgin Olive Oil in Clinical Nutrition: A Narrative Review and Literature Update. Nutrients 2022; 14:nu14071440. [PMID: 35406067 PMCID: PMC9003415 DOI: 10.3390/nu14071440] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 03/24/2022] [Accepted: 03/25/2022] [Indexed: 02/06/2023] Open
Abstract
Extra virgin olive oil (EVOO) is a cornerstone of the Mediterranean diet (MedD). In this narrative review, we synthesize and illustrate the various characteristics and clinical applications of EVOO and its components—such as oleic acid, hydroxytyrosol, and oleuropein—in the field of clinical nutrition and dietetics. The evidence is split into diet therapy, oleic acid-based enteral nutrition formulations and oral supplementation formulations, oleic acid-based parenteral nutrition, and nutraceutical supplementation of minor components of EVOO. EVOO has diverse beneficial health properties, and current evidence supports the use of whole EVOO in diet therapy and the supplementation of its minor components to improve cardiovascular health, lipoprotein metabolism, and diabetes mellitus in clinical nutrition. Nevertheless, more intervention studies in humans are needed to chisel specific recommendations for its therapeutic use through different formulations in other specific diseases and clinical populations.

Abstract
Listeria monocytogenes is a regulated foodborne pathogen that is known to cause listeriosis, a disease associated with high mortality rates in humans. Olive leaf extract (OLE) has been shown to act as a plant antimicrobial and inhibit the growth of pathogens, such as L. monocytogenes, although its mode of action has not been defined. To help identify the cellular mechanisms important for conveying these beneficial traits, RNA-Seq was used to study the transcriptome of L. monocytogenes upon exposure to a sublethal level of OLE. Results obtained from cells cultured both with and without OLE at two different time points (3.5-h and 24-h) revealed 661 genes that were differentially expressed. Of the differentially expressed genes (DEGs) identified, transcription was altered for 171 genes in response to the 3.5-h OLE treatment while 490 genes were altered in response to the 24-h OLE treatment. These DEGs included but were not limited to genes encoding for signal transduction, ATP-binding cassette (ABC) transporters, and the phosphotransferase system. Interestingly, several virulence-related genes were downregulated including an ABC transporter permease previously shown to negatively regulate biofilm formation, genes involved in flagella assembly and binding/entry into host cells as well as those regulating acid resistance suggesting that OLE may decrease the virulence potential of L. monocytogenes. Furthermore, quantitative reverse-transcription PCR was used to validate the data obtained via RNA-Seq. Our study provides insight into the mode of action of OLE treatment against L. monocytogenes and may aid in identifying synergetic strategies to inhibit L. monocytogenes in food.

Abstract
Introduction: Rheumatoid arthritis (RA) is an autoimmune disease that is identified with
chronic inflammation and progressive destruction of the joints. The
defective activity of regulatory T cells (Tregs) plays a crucial role in RA
development. Oleuropein (OLEU) is the most common polyphenolic compound in
olive leaf extracts with numerous pharmacological activities. In this study,
the potential effects of OLEU in shifting CD4+ T cells toward
Tregs are evaluated in patients with RA. Methods 32 healthy controls (HC) and 45 RA patients were included in two groups. The
immunoturbidometric technique was used to measure serum levels of c-reactive
protein (CRP) and rheumatoid factor (RF). Isolated CD4+ T cells
from peripheral blood mononuclear cells (PBMCs) of HC and RA patients were
cultured with appropriate concentrations of OLEU. The cytotoxicity effects
of OLEU were determined using the MTT assay at 24, 48, and 72 h. The
percentage of CD4+CD25 + FoxP3 regulatory T lymphocytes (Tregs)
and the expressions of IL-10 and TGF-β were evaluated by flow cytometry and
immunoassay techniques after treatment of cells with different
concentrations of OLEU for 24 h. The serum levels of RF and CRP in patients
with RA were 11.8 ± 5.32 IU/ml and 6.36 ± 5.82 mg/l, respectively. Results OLEU had a dose-dependent effect on the CD4+ T cells via
increasing the frequency of CD4+CD25 + FoxP3 Tregs
(p = 0.0001). Moreover, it induced the production of
IL-10 (p = 0.0001) and TGF-β (p < 0.01)
in both HC and RA patients. Conclusion The findings of this study suggest that OLEU may have immunomodulatory
effects by inducing Tregs, and it might help in developing a novel nutrition
strategy for management of autoimmune diseases such as RA.

Abstract
Medicinal plants are widely used as a complementary therapy to treat complex diseases, such as nonalcoholic fatty liver disease (NAFLD). Therefore, this study was done to investigate the effect of co-administration of artichoke leaf extract supplement (ALES) with conventional medicines on patients with NAFLD. The clinical trial was based on patients randomly divided into three groups involving metformin-vitamin E (ME), metformin-ALES (MA), and vitamin E-ALES (EA). The effectiveness of treatment in the treated groups was evaluated using liver ultrasonography and biochemical markers. After 12 weeks of treatment, the results showed that the rate of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was significantly reduced within all the study groups (p < .05). Liver ultrasonographic findings revealed that the rate of fat accumulation in liver of patients was decreased significantly within all the study groups and it was increased in the subjects with grade 0 fatty liver (without fat accumulation) in the MA and EA groups by 23.3 and 17.2%, respectively. In summary, the results of the present study showed that the concomitant use of ALES with metformin and vitamin E can have beneficial effects on amelioration of complications in patients with NAFLD. However, larger-scale clinical trial studies are required in this regard.

Abstract
The protective activity of dry olive leaf extract (DOLE) in carbon tetrachloride (CCl4)-induced liver damage and possible mechanisms involved in this protection were investigated in rats. Acute CCl4 intoxication resulted in a massive hepatic necrosis, in increased serum transaminases, and in a perturbation of oxidative stress parameters in liver tissue [malondyaldehide, glutathione (GSH), catalase]. CCl4 did not affect the expression of caspase-3 and cytochrome c as markers of apoptosis; however, CCl4 increased the AMP-activated protein kinase (AMPK) activity and the expression of autophagy-related protein LC3II and decreased the expression of p62 protein. The pre-treatment with DOLE significantly improved serum markers of liver damage, liver catalase activity, and GSH concentration, suggesting that antioxidative mechanism is responsible for hepatoprotection. Oral administration of DOLE did not influence LC3II conversion and p62 degradation in liver, but AMPK activity was significantly decreased, suggesting the energy balance perturbation as an additional potential mechanism of DOLE hepatoprotective effect.

Abstract
Oleuropein (Ole) is the main bioactive phenolic compound present in olive leaves, fruits and olive oil. This molecule has been shown to exert beneficial effects on several human pathological conditions. In particular, recent preclinical and observational studies have provided evidence that Ole exhibits chemo-preventive effects on different types of human tumors. Studies undertaken to elucidate the specific mechanisms underlying these effects have shown that this molecule may thwart several key steps of malignant progression, including tumor cell proliferation, survival, angiogenesis, invasion and metastasis, by modulating the expression and activity of several growth factors, cytokines, adhesion molecules and enzymes involved in these processes. Interestingly, experimental observations have highlighted the fact that most of these signalling molecules also appear to be actively involved in the homing and growth of disseminating cancer cells in bones and, ultimately, in the development of metastatic bone diseases. These findings, and the experimental and clinical data reporting the preventive activity of Ole on various pathological conditions associated with a bone loss, are indicative of a potential therapeutic role of this molecule in the prevention and treatment of cancer-related bone diseases. This paper provides a current overview regarding the molecular mechanisms and the experimental findings underpinning a possible clinical role of Ole in the prevention and development of cancer-related bone diseases.

Abstract
The aim of this study was to determine serum lipid values and parameters of oxidative stress in blood and milk of cows with subclinical mastitis (SCM) caused by Staphylococcus aureus and to establish association between these parameters. The study was performed on total of 104 cows assigned into control group of healthy animals (n = 12) and two groups of cows with SCM, either SCM1 group (n = 37) with ˂ 1000 CFU/mL of S. aureus or SCM2 group (n = 55) with ≥1000 CFU/mL of causative agent in milk. Significantly lower serum concentrations of high density lipoprotein-cholesterol (HDLC) in SCM2 group and higher low density lipoprotein-cholesterol (LDL-C) in both SCM groups were recorded. Significantly lower paraoxonase-1 (PON1) activity and higher lipid hydroperoxides (LOOH) concentration in blood and milk were recorded in both groups of SCM cows vs control. In blood serum of cows from SCM2 group significantly higher concentrations of hydrogen peroxide (H2O2) and malondialdehyde (MDA), but significantly lower total antioxidative capacity (TAC) were obtained. In milk serum of SCM cows were detected significantly higher concentrations of H2O2 and MDA, but significantly lower TAC vs control. There was a significant positive correlation between PON1 in serum with HDLC, but negative correlation with LDL-C and LOOH. In milk, PON1 negatively correlated with LOOH and somatic cell counts (SCC). Strong positive correlation was obtained between PON1 in blood and milk. Oxidative stress and inflammatory reaction induced by SCM significantly lowered PON1 activity in blood and milk of affected cows.

Abstract
The current therapeutic scenario for inflammatory bowel diseases (IBD) involves aminosalicylates, corticosteroids, and immunomodulators, but concerns regarding their safety profiles and high costs heavily impact their widespread use. In recent years, the beneficial effects thatbiophenols—from fruit and vegetables—have on human health have been investigated. The antioxidant and anti-inflammatory properties of phenolic fraction, from olive leaves and fruits, have been suggested, and a potential application in gut inflammation has been supported by in vitro and IBD-animal models studies. In the present review, we first introduced the potential therapeutic role of olive tree biophenolsin chronic inflammatory disease. Then, we aimed to describe their most interesting application for gut inflammation, as the results of basic science studies and animal experimental models. Finally, the potential role of olive tree biophenols in the setting of human IBD is discussed.
