RESUMO

Cannabidiol (CBD) is a multitarget agent possessing anti-inflammatory and antioxidant properties. Unlicensed CBD gained public favor for the care of general health and well-being as well as to get comfort from inflammatory complaints, pain, anxiety, mood, and sleep disorders. Safety profile of unlicensed CBD has been not sufficiently described. For this reason, suspected adverse reactions (SARs) to CBD unlicensed products were analyzed. Serious SARs to unlicensed CBD products in EudraVigilance, a system purchased by the European Medicines Agency, were analyzed for age, sex of the patient, adverse reactions, indication for use, and concomitant drugs. Serious SARs were 18.9% of all adverse events to unlicensed CBD; they were more frequent in men and adult people and, to a less extent, in children (3-11 years). About sex, in EudraVigilance serious Individual Cases Safety Reports of SARs to CBD in men are in the largest number (58.8%) with respect to women. Unlicensed CBD was used in the 38.8% of cases for treatment of epilepsy; more frequent adverse effects were: mental disorders, hepatic disorders, and aggravation of pre-existing epilepsy. Drugs or substances more frequently associated with SARs were the antiepileptics clobazam and valproic acid, followed by cannabis. Results suggest that precautions and appropriate surveillance of adverse effects should be taken when unlicensed CBD is used.

RESUMO

Recently, there has been a renewed interest in Cannabis sativa and its uses. The recreational use of inflorescences as a source of THC has led to the legal restriction of C. sativa cultivation to limit the detrimental effects of psychotropic substance abuse on health. However, this has also limited the cultivation of textile/industrial varieties with a low content of THC used for textile and nutritional purposes. While previously the bans had significantly penalized the cultivation of C. sativa, today many countries discriminate between recreational use (marijuana) and industrial and food use (hemp). The stalks of industrial hemp (low in psychotropic substances) have been used extensively for textile purposes while the seeds are nutritionally versatile. From hemp seeds, it is possible to obtain flours applicable in the bakery sector, oils rich in essential fatty acids, proteins with a high biological value and derivatives for fortification, supplementation and nutraceutical purposes. Hemp seed properties seem relevant for vegetarian diets, due to their high nutritional value and underestimated employment in the food sector. Hemp seed and their derivatives are a valuable source of protein, essential fatty acids and minerals that could provide additional benefit to vegetarian nutrition. This document aims to explore the information available in the literature about hemp seeds from a nutritional point of view, highlighting possible beneficial effects for humans with particular attention to vegetarian nutrition as a supplemental option for a well-planned diet.

RESUMO

Cannabigerol (CBG) is a cannabinoid from the plant Cannabis sativa that lacks psychotomimetic effects. Its precursor is the acidic form, cannabigerolic acid (CBGA), which is, in turn, a biosynthetic precursor of the compounds cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC). CBGA decarboxylation leads to the formation of neutral cannabinoid CBG, through a chemical reaction catalyzed by heat. On the basis of the growing interest in CBG and with the aim of highlighting scientific information on this phytocannabinoid, we focused the content of this article on its pharmacokinetic and pharmacodynamic characteristics and on its principal pharmacological effects. CBG is metabolized in the liver by the enzyme CYP2J2 to produce hydroxyl and di-oxygenated products. CBG is considered a partial agonist at the CB1 receptor (R) and CB2R, as well as a regulator of endocannabinoid signaling. Potential pharmacological targets for CBG include transient receptor potential (TRP) channels, cyclooxygenase (COX-1 and COX-2) enzymes, cannabinoid, 5-HT1A, and alpha-2 receptors. Pre-clinical findings show that CBG reduces intraocular pressure, possesses antioxidant, anti-inflammatory, and anti-tumoral activities, and has anti-anxiety, neuroprotective, dermatological, and appetite-stimulating effects. Several findings suggest that research on CBG deserves to be deepened, as it could be used, alone or in association, for novel therapeutic approaches for several disorders.

RESUMO

Aim: Coffee intake is common during pregnancy. However, the influence of coffee and caffeine on pregnancy has not yet been fully determined. Some studies show that high coffee intake could cause miscarriage, preterm birth or reduction of fetal growth, but other studies do not support these findings. The aim of the present study was to analyze data collected from a database focusing on coffee intake during pregnancy, which was specifically created for multicenter studies carried out in the maternity units of Italian general hospitals. Principal outcomes of pregnancy during pregnancy were considered. Methods: Data of 5405 pregnancies were collected by a direct questionnaire supplemented with data from patients'clinical records during the survey named PHYTO.VIG.GEST. Results: We observed that 42.3% of the total sample had consumed at least one coffee a day during pregnancy. Analysis of a dose-response relationship showed that, in pregnant women starting from the consumption of three coffees a day (6% of pregnant women consuming coffee), there is a statistically significant association between number of coffees and reduction of babies birth weight (< 2500 g). Coclusion: Even though high coffee intake is known to influence negatively birth weight, our results indicate that a significant percentage of pregnant women maintain this habit.

RESUMO

The plant kingdom has always been a treasure trove for valuable bioactive compounds, and Citrus fruits stand out among the others. Bergamottin (BRG) and 5-geranyloxy-7-methoxycoumarin (5-G-7-MOC) are two coumarins found in different Citrus species with well-acknowledged pharmacological properties. Previously, they have been claimed to be relevant in the anti-proliferative effects exerted by bergamot essential oil (BEO) in the SH-SY5Y human neuroblastoma cells. This study was designed to verify this assumption and to assess the mechanisms underlying the anti-proliferative effect of both compounds. Our results demonstrate that BRG and 5-G-7-MOC are able to reduce the proliferation of SH-SY5Y cells, inducing apoptosis and increasing cell population in sub-G0/G1 phase. Moreover, we demonstrated the pro-oxidant activity of the two coumarins that increased reactive oxygen species and impaired mitochondrial membrane potential. From a molecular point of view, BRG and 5-G-7-MOC were able to modulate apoptosis related factors at both protein and gene levels. Lastly, we evaluated the synergistic effect of their combination, finding that the highest synergy was observed at a concentration ratio similar to that occurring in the BEO, supporting our initial hypothesis. Taken together, our results deepen the knowledge regarding the effect of BRG and 5-G-7-MOC in SH-SY5Y cells, emphasizing the relevance of their cooperation in achieving this effect.

RESUMO

Gastrointestinal discomfort (GD), which often includes gastroesophageal reflux disease (GERD), is a common disorder in healthy adults affecting 40% of the worldwide population. The symptoms related to GD can have a negative impact on the quality of life (QoL). Current treatments for GERD are associated with side effects. We conducted a randomized double-blind placebo-controlled trial to assess the effect of a standardized extract of Opuntia ficus-indica L. cladodes and Olea europaea L. leaves on the symptoms and QoL of healthy adults with GD. One hundred healthy participants with GD were enrolled in the study and divided into two groups: 60 participants taking verum (400 mg/day) and 40 taking the placebo for 8 weeks. The Gastrointestinal Quality of Life index (GIQLI) and GERD Symptom Assessment Scale (GSAS) questionnaires were administered at the beginning of the study and after 4 and 8 weeks. The group treated with verum experienced a statistically significant improvement of GIQLI and GSAS scores (p < .001). Moreover, the effect size measured revealed a clinical significance. A day-dependent improvement of symptoms was also observed. The standardized extract represents a fast, effective, and well-tolerated treatment for improving symptoms related to GD and GERD.

RESUMO

Antioxidant mechanisms are constituted of enzymes, endogenous, and non-enzymatic, exogenous, which have the role of counterbalancing oxidative stress. Intake of these compounds occurs in the diet. Vegetables, plants, and fruits contain a wide range of alkaloids, polyphenols, and terpenoids which are called "phytochemicals". Most of these substances are responsible for the positive properties of fruits and vegetables, which are an essential part of a healthy life with roles in ameliorating chronic illnesses and favoring longevity. Nutraceuticals are substances contained in a food or fragment of it influencing health with positive effects on health helping in precenting or treating disorders. We conducted a review illustrating the principal applications of nutraceuticals in autoimmune disorders. Literature reported several studies about exogenous dietary antioxidant supplementation in diverse autoimmune diseases such as rheumatoid arthritis, lupus, diabetes, and multiple sclerosis. In these pathologies, promising results were obtained in some cases. Positive outcomes were generally associated with a reduction of oxidative stress parameters and a boost to antioxidant systems, and sometimes with anti-inflammatory effects. The administration of exogenous substances through food derivates or dietary supplements following scientific standardization was demonstrated to be effective. Further bias-free and extended studies should be conducted that include ever-increasing oxidative stress biomarkers.

RESUMO

BACKGROUND: Acute cough in children often causes discomfort to children and parents, reducing their quality of life. Despite the extensive utilization of over-the-counter remedies for cough, the efficacy of most of these treatments in children has not been confirmed. METHODS: We conducted a randomized, double blind, placebo-controlled clinical trial of 106 children with acute cough to evaluate the efficacy and safety of KalobaTUSS®, a paediatric cough syrup based on acacia honey and on Malva sylvestris extract, Inula helenium extract, Plantago major extract, and Helichrysum stoechas extract by using a validated 6 points Likert scale. RESULTS: Children were orally treated with KalobaTUSS® or placebo for 8 days. Children receiving KalobaTUSS® showed an early and significant reduction in night-time and day-time cough scores measured using a specific scale and a shorter duration of cough than children treated with the placebo. CONCLUSIONS: KalobaTUSS® is well tolerated and produces positive effects by reducing the severity and shortening the duration of cough in children. TRIAL REGISTRATION: Clinicaltrials.gov no. NCT04073251 . Retrospectively registered.

RESUMO

BACKGROUND: Omega-3 fatty acids (FAs) can produce several beneficial effects and are commonly used for the treatment of migraine symptoms. Although current therapeutic measures for migraine included pharmacological therapies, dietary supplements, and herbal ingredients, dietary patterns, acupuncture, relaxation techniques, biofeedback, and psychotherapy, omega-3 FAs therapeutic role seems to be obtained through the inhibition or reduction of the release of inflammatory cytokines. The present review aims to provide updated information about the effects of omega-3 FAs in migraine treatment, investigating their clinical effects alone or in combination with other substances. METHODS: Bibliographic research was conducted by examining scientific literature from January 2000 until January 31, 2020. Ten clinical studies were included in the review. Quality assessment of randomized controlled trials was performed by using the JADAD scale. RESULTS: Clinical studies methodology is not always of good quality and results show moderate evidence concerning the therapeutic role of omega-3 FAs in migraine. CONCLUSION: Further clinical trials are necessary to implement the knowledge concerning the use of omega-3 fatty acids in the treatment of migraine.

RESUMO

Inflammatory bowel disease (IBD), with its major manifestations being Crohn's disease and ulcerative colitis, belongs to the gastrointestinal inflammatory disorders, whose main therapeutic approach is represented by synthetic anti-inflammatory drugs. However, they are often accompanied by many side effects that shifted the interest of the scientific community towards natural products. In this context, several studies asserted the anti-IBD effects of Citrus fruits and their flavonoids, thus the aim of the present review is to provide robust evidence favouring their role in the prevention and treatment of IBD. Key mechanisms relate to their anti-inflammatory and antioxidant properties, as well as their ability to modulate gut microbiota. All the findings collected in this review, lay the foundations for further studies in human with the aim of evaluating the concrete applicability as a novel preventive and therapeutic approach of Citrus fruits and their flavonoids.[Figure: see text].

RESUMO

BACKGROUND: Cannabidiol (CBD) is a major chemical compound present in Cannabis sativa. CBD is a nonpsychotomimetic substance, and it is considered one of the most promising candidates for the treatment of psychiatric disorders. OBJECTIVE: The aim of this review is to illustrate the state of art about scientific research and the evidence of effectiveness of CBD in psychiatric patients. METHODS: This review collects the main scientific findings on the potential role of CBD in the psychiatric field, and results of clinical trials carried out on psychiatric patients are commented. A research was conducted in the PUBMED, SCOPUS, and ScienceDirect databases using combinations of the words cannabidiol, psychiatry, and neuropsychiatric. RESULTS: Preclinical and clinical studies on potential role of CBD in psychiatry were collected and further discussed. We found four clinical studies describing the effects of CBD in psychiatric patients: two studies about schizophrenic patients and the other two studies carried out on CBD effects in patients affected by generalized social anxiety disorder (SAD). CONCLUSION: Results from these studies are promising and suggest that CBD may have a role in the development of new therapeutic strategies in mental diseases, and they justify an in-depth commitment in this field. However, clinical evidence we show for CBD in psychiatric patients is instead still poor and limited to schizophrenia and anxiety, and it needs to be implemented with further studies carried out on psychiatric patients.

RESUMO

OBJECTIVE: This study aimed to evaluate pain and its symptoms in patients with failed back surgery syndrome (FBSS) refractory to other therapies, treated with a combination of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), in association with spinal cord stimulation (SCS). SETTINGS: Outpatients referred at Pain Unit of San Vincenzo Hospital in Taormina (Italy), between September 2014 and January 2016. SUBJECTS: Eleven FBSS patients diagnosed with neuropathic pain using the Douleur Neuropathique 4 questionnaire and suffering from moderate to severe chronic refractory pain, and undergoing treatment with SCS and a combination of THC/CBD for 12 consecutive months. MATERIALS AND METHODS: All the included patients discontinued previous unsuccessful therapy at least 2 months before the beginning of the cannabinoid therapy, with the exception of the SCS that was continued. Patients received a fixed dosage of cannabinoid agonists (THC/CBD) that could be increased subjective to pain control response. A Brief Pain Inventory questionnaire was administered to measure pain and its interference with characteristic dimensions of feelings and functions. The duration of treatment with SCS and THC/CBD combination was 12 months. RESULTS: Effective pain management as compared to baseline result was achieved in all the cases studied. The positive effect of cannabinoid agonists on refractory pain was maintained during the entire duration of treatment with minimal dosage titration. Pain perception, evaluated through numeric rating scale, decreased from a baseline mean value of 8.18±1.07-4.72±0.9 by the end of the study duration (12 months) (P<0.001). CONCLUSION: The results indicate that cannabinoid agonists (THC/CBD) can have remarkable analgesic capabilities, as adjuvant of SCS, for the treatment of chronic refractory pain of FBSS patients.

RESUMO

OBJECTIVE: The aim of this review is to analyze preclinical and clinical studies investigating the anxiety effects of Citrus aurantium or Citrus sinensis essential oils (EOs). DESIGN: The bibliographic research was made on the major scientific databases. Analysis included only articles written in English and published on peer-reviewed scientific journals describing preclinical experiments and clinical trials carried out to investigate the antianxiety effects of Citrus aurantium or Citrus sinensis EOs on anxiety disorders. Clinical studies reporting the antianxiety effects of products containing Citrus aurantium or Citrus sinensis EOs in combination with other active substances, including medicinal plants, were excluded. Nine clinical studies fulfilled the criteria adopted for analysis. RESULTS: Data show that Citrus aurantium or Citrus sinensis EOs produce anxiolytic effects both in preclinical experiments and in different clinical conditions. Citrus aurantium EO aromatherapy reduced anxiety level in the great part of stress conditions studied (subjects affected by chronic myeloid leukemia and preoperative patients) except for a sample of patients subjected to colonoscopy. Exposition to Citrus sinensis EO in clinical studies shows to be positive in reducing anxiety level in patients waiting for dental treatment as well as in healthy volunteers submitted to an anxiogenic situation. CONCLUSIONS: Overview of clinical trials conducted with Citrus aurantium or Citrus sinensis on people with anxiety showed that inhalation or oral administration of Citrus aurantium and inhalation of Citrus sinensis can exert beneficial effects on anxiety; however, because of incomplete accuracy in the reporting of methodology, further more complete clinical studies are warranted.

RESUMO

PURPOSE: Dry eye disease (DED) is a common condition causing substantial burden. A randomized, controlled, single-masked study was performed in 40 patients with mild to moderate DED to evaluate the efficacy and safety of a collyrium based on crosslinked hyaluronic acid (XLHA) with coenzyme Q10 (CoQ10). METHODS: Enrolled subjects were divided into 2 groups: group A, treated with XLHA + CoQ10; and group B, treated with hyaluronic acid (HA). Eyedrops were administered 4 times daily for 3 months. The Ocular Surface Disease Index (OSDI) questionnaire, tear break-up time (TBUT), corneal and conjunctival staining, and meibomian gland assessment (MGD) were evaluated; furthermore, corneal aesthesiometry, in vivo corneal confocal microscopy, visual acuity, intraocular pressure (IOP), and fundus examination were performed. RESULTS: At the end of treatment, OSDI score significantly decreased in groups A and B (p<0.01 and p<0.05, respectively); the decrease was significantly higher in group A. Corneal staining decreased in both groups, with lower scores in group A. The MGD was significantly ameliorated in group A patients. No differences were found for corneal aesthesiometry or TBUT. Epithelial cell reflectivity was significantly reduced only in group A. For keratocytes and stromal matrix parameters, there was a significant improvement in group A. No changes were found for visual acuity, IOP, or fundus examination. CONCLUSIONS: The XLHA + CoQ10 treatment showed greater effectiveness in DED compared to HA alone, probably due to the longer permanency on ocular surface and the antioxidant activity of CoQ10. Therefore, XLHA + CoQ10 eyedrops could represent a new possibility in dry eye treatment.

RESUMO

BACKGROUND: Cannabidiol (CBD) is among the major secondary metabolites of Cannabis devoid of the delta-9-tetra-hydrocannabinol psychoactive effects. It is a resorcinol-based compound with a broad spectrum of potential therapeutic properties, including neuroprotective effects in numerous pathological conditions. CBD neuroprotection is due to its antioxidant and antiinflammatory activities and the modulation of a large number of brain biological targets (receptors, channels) involved in the development and maintenance of neurodegenerative diseases. OBJECTIVE: The aim of the present review was to describe the state of art about the pre-clinical research, the potential use and, when existing, the clinical evidence related to CBD in the neurological field. METHOD: Collection of all the pre-clinical and clinical findings carried out investigating the effects of CBD alone, not in combination with other substances, in the neurological arena with the exclusion of studies on neuropsychiatric disorders. RESULTS: Laboratory and clinical studies on the potential role of CBD in Parkinson's disease (PD), Alzheimer's disease (AD), multiple sclerosis (MS), Huntington's disease (HD), amyotrophic lateral sclerosis ALS), cerebral ischemia, were examined. CONCLUSION: Pre-clinical evidence largely shows that CBD can produce beneficial effects in AD, PD and MS patients, but its employment for these disorders needs further confirmation from well designed clinical studies. CBD pre-clinical demonstration of antiepileptic activity is supported by recent clinical studies in human epileptic subjects resistant to standard antiepileptic drugs showing its potential use in children and young adults affected by refractory epilepsy. Evidence for use of CBD in PD is still not supported by sufficient data whereas only a few studies including a small number of patients are available.

RESUMO

Citrus bergamia Risso et Poiteau ("Bergamot") originated from the Mediterranean ecoregion (southern Italy, Calabria). Bergamot essential oil (BEO) is used in perfumes, cosmetics, and for stress reduction. Juice from C. bergamia has been used for hyperlipidemia. We evaluated literature published on C. bergamia clinical applications. Clinical trials on C. bergamia not combined with other substances, published in English, were searched. We selected ten articles, six describing BEO effects on stress, three reporting effects of polyphenolic fraction of C. bergamia juice in hyperlipidemia and the last describing BEO effects in chronic psoriasis. Clinical studies were analyzed following Consolidated Standards of Reporting Trials for herbal therapy. Studies were conducted on small sample sizes and not have high quality level. Analysis indicates that BEO aromatherapy could be safe and useful to reduce stress symptoms. One study suggests its potential supportive role in ultraviolet B therapy against psoriasis. Supplementation with polyphenols from bergamot juice reduces plasma lipids and improves lipoprotein profile in moderate hyperlipidemia. Effectiveness and safety of C. bergamia cannot be definitively drawn because of publication bias and low quality level of the majority of studies. Further large-scale trials with rigorous design are required to define the role of C. bergamia in clinical practice. Copyright © 2016 John Wiley & Sons, Ltd.

RESUMO

Fruits and vegetables have long been recognized as potentially important in the prevention of cancer risk. Thus, scientific interest in nutrition and cancer has grown over time, as shown by increasing number of experimental studies about the relationship between diet and cancer development. This review attempts to provide an insight into the anti-cancer effects of Citrus fruits, with a focus on their bioactive compounds, elucidating the main cellular and molecular mechanisms through which they may protect against cancer. Scientific literature was selected for this review with the aim of collecting the relevant experimental evidence for the anti-cancer effects of Citrus fruits and their flavonoids. The findings discussed in this review strongly support their potential as anti-cancer agents, and may represent a scientific basis to develop nutraceuticals, food supplements, or complementary and alternative drugs in a context of a multi-target pharmacological strategy in the oncology.

RESUMO

Gastroesophageal reflux (GER) is a common, chronic, relapsing symptom. Often people self-diagnose and self-treat it even though health-related quality of life is significantly impaired. In the lack of a valid alternative approach, current treatments focus on suppression of gastric acid secretion by the use of proton pump inhibitors (PPIs), but people with GER have a significantly lower response rate to therapy. We designed a randomized double-blinded controlled clinical study to evaluate the efficacy and the safety of a formulation based on sodium alginate/bicarbonate in combination with extracts obtained from Opuntia ficus-indica and Olea europaea associated with polyphenols (Mucosave®; verum), on GER-related symptoms. Male/female 118 (intention to treat) subjects with moderate GER and having at least 2 to 6 days of GER episodes/week were treated with verum (6 g/day) or placebo for two months. The questionnaires Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQoL) and Gastroesophageal Reflux Disease Symptom Assessment Scale (GSAS) were self-administered by participants before the treatment and at the end of the treatment. Verum produced statistically significant reduction of GERD-HRQoL and GSAS scores, -56.5% and -59.1%, respectively, in comparison to placebo. Heartburn and acid regurgitation episodes for week were significantly reduced by verum (p < 0.01). Results indicate that Mucosave formulation provides an effective and well-tolerated treatment for reducing the frequency and intensity of symptoms associated with gastroesophageal reflux.

RESUMO

Inflammatory diseases affect a large portion of the worldwide population, and chronic inflammation is a major risk factor for several dangerous pathologies. To limit the side effects of both synthetic and biological anti-inflammatory drugs, the use of herbal medicines, nutraceuticals and food supplements has increased tremendously as alternative and/or complementary medicine to treat several pathologies, including inflammation. During the last decades, the biological properties of Citrus bergamia (bergamot) derivatives have obtained important scientific achievements, and it has been suggested their use in a context of a multitarget pharmacological strategy. Here, we present an overview of the anti-inflammatory properties of bergamot extracts that could represent the scientific basis for develop novel and alternative strategies to improve health status and attenuate inflammatory conditions.
