A novel azelaic acid formulation for the topical treatment of inflammatory rosacea: A multicentre, prospective clinical trial. J Cosmet Dermatol 2021; 20 Suppl 1:28-31. [PMID: 33934475 PMCID: PMC8252084 DOI: 10.1111/jocd.14098] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/16/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Topical azelaic acid (AzA) is a common treatment for mild/moderate inflammatory rosacea. AIMS To assess the efficacy and tolerability of a novel formulation cream containing 15% AzA (anti-inflammatory/anti-oxidant/anti-microbial agent) combined with 1% dihydroavenanthramide D (anti-inflammatory/anti-itch) in inflammatory rosacea using clinical/instrumental evaluation. METHODS In this multicentre, prospective, open-label trial, 45 patients with mild/moderate inflammatory rosacea enrolled at the Dermatology Clinic of the University of Catania, Naples, and Rome (Italy) were instructed to apply the cream twice daily for 8 weeks. Clinical evaluation was performed at baseline (T0) and at 8 weeks (T1) by (1) Investigator Global Assessment (IGA) score based on a 5-point scale (from 0 = clear/no erythema/papules/pustules to 4 = severe erythema/several papules/pustules) and (2) inflammatory lesions count. Instrumental evaluation of erythema degree was performed by erythema-directed digital photography (EDDP) by a 5-point scale (from 0 = no redness to 4 = severe redness) at all time points. Tolerability was assessed by a self-administered questionnaire at 8 weeks. Statistical analysis was performed using SAS version 9. RESULTS Forty-four patients completed the study. At week 8, a significant decrease in baseline of IGA scores [median from 3 (T0) to 1 (T1)] and inflammatory lesions count [median from 8 (T0) to 1 (T1)] was recorded along with a significant reduction of erythema scores [median from 2 (T0) to 1 (T1)]. No relevant side effects were recorded. CONCLUSIONS Our results suggest that this new non-irritating product represents a valid therapeutic option for mild/moderate inflammatory rosacea, and EDDP is able to provide a more defined evaluation of erythema changes.

Biomed Pharmacother 2020; 131:110762. [PMID: 33152925 DOI: 10.1016/j.biopha.2020.110762] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 09/14/2020] [Accepted: 09/16/2020] [Indexed: 12/12/2022] Open
Abstract
Phenolamides constitute a family of metabolites, widely represented in the plant kingdom, that can be found in all plant organs with a predominance in flowers and pollen grains. They represent a large and structurally diverse family, resulting from the association of phenolic acids with aliphatic or aromatic amines. Initially revealed as active compounds in several medicinal plant extracts, phenolamides have been extensively studied for their health-promoting and pharmacological properties. Indeed, phenolamides have been shown to exhibit antioxidant, anti-inflammatory, anti-cancer and antimicrobial properties, but also protective effects against metabolic syndrome and neurodegenerative diseases. The purpose of this review is to summarise this large body of literature, including in vitro and in vivo studies, by describing the diversity of their biological properties and our actual knowledge of the molecular mechanisms behind them. With regard to their considerable pharmacological interest, the question of industrial production is also tackled through chemical and biological syntheses in engineered microorganisms. The diversity of biological activities already described, together with the active discovery of the broad structural diversity of this metabolite family, make phenolamides a promising source of new active compounds on which future studies should be focused.

Sci Rep 2019; 9:6884. [PMID: 31053741 PMCID: PMC6499795 DOI: 10.1038/s41598-019-43412-2] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2018] [Accepted: 01/21/2019] [Indexed: 12/19/2022] Open
Abstract
Mast cells play a crucial role in allergic diseases via the release of inflammatory mediators, particularly histamine and pro-inflammatory cytokines. Avenanthramide (Avn) C, a polyphenol found mainly in oats, is known to exhibit various biological properties. In this study, we aimed to evaluate the effectiveness of Avn C from germinated oats against mast cell-mediated allergic inflammation. For the in vitro study, RBL-2H3, mouse bone marrow-derived mast cells and rat peritoneal mast cells were used. Avn C (1–100 nM) inhibited the immunoglobulin (Ig)E-stimulated mast cells degranulation by suppressing phosphorylation of phosphoinositide 3-kinase and phospholipase Cγ1 and decreasing intracellular calcium levels. It inhibited IgE-stimulated secretion of inflammatory cytokines via suppression of FcεRI-mediated signaling proteins Lyn, Syk, Akt, and nuclear factor-κB. To verify the effects of Avn C in vivo, ovalbumin-induced active systemic anaphylaxis (ASA) and IgE-mediated passive cutaneous anaphylaxis (PCA) models were used. Oral administration of Avn C dose-dependently attenuated the ASA reactions, as evidenced by the inhibition of hypothermia and reduction of elevated serum histamine, IgE, and interleukin-4 levels. Avn C also inhibited the PCA reactions, such as ear swelling and plasma extravasation. Our results suggested that Avn C from germinated oats might be a possible therapeutic candidate for mast cell-mediated allergic inflammation.

Neuropeptide Initiated Mast Cell Activation by Transcutaneous Electrical Acupoint Stimulation of Acupoint LI4 in Rats. Sci Rep 2018; 8:13921. [PMID: 30224712 PMCID: PMC6141543 DOI: 10.1038/s41598-018-32048-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2018] [Accepted: 08/17/2018] [Indexed: 12/21/2022] Open
Abstract
Transcutaneous electrical acupoint stimulation (TEAS) has been consistently used clinically for its ease of operation, non-invasiveness and painlessness, in contrast to the characteristics of inserted needles. However, the mechanism remains unknown. The aim of this study was to investigate the local response of TEAS at Hegu acupoint (LI4). Immunohistochemistry was used to measure the expression of tryptase-positive mast cells, neuropeptides of the calcitonin gene-related peptide (CGRP) and substance P (SP) in LI4. Mast cells were also labelled with serotonin (5-HT), neurokinin-1 receptor (NK-1R) and toluidine blue. The results showed that cutaneous CGRP and SP immune-positive (CGRP-IP or SP-IP) nerve fibres in LI4 were more highly expressed. There were high degrees of mast cell aggregation and degranulation with release of 5-HT near the CGRP-IP or SP-IP nerve fibres and blood vessels after TEAS. The degranulation of mast cells (MCs) was accompanied by expression of NK-1R after TEAS. Either mast cell membrane stabilizer (Disodium cromoglycate) or NK-1R antagonist (RP 67580) diminished the accumulation and degranulation of MCs induced by TEAS. Taken together, the findings demonstrated that TEAS induced sensory nerve fibres to express CGRP and SP, which then bound to the NK-1R on MCs, after which MCs degranulated and released 5-HT, resulting in TEAS-initiated acupuncture-like signals.

Abstract
Oat (Avena sativa) is a cereal known since antiquity as a useful grain with abundant nutritional and health benefits. It contains distinct molecular components with high antioxidant activity, such as tocopherols, tocotrienols, and flavanoids. In addition, it is a unique source of avenanthramides, phenolic amides containing anthranilic acid and hydroxycinnamic acid moieties, and endowed with major beneficial health properties because of their antioxidant, anti-inflammatory, and antiproliferative effects. In this review, we report on the biological activities of avenanthramides and their derivatives, including analogs produced in recombinant yeast, with a major focus on the therapeutic potential of these secondary metabolites in the treatment of aging-related human diseases. Moreover, we also present recent advances pointing to avenanthramides as interesting therapeutic candidates for the treatment of cerebral cavernous malformation (CCM) disease, a major cerebrovascular disorder affecting up to 0.5% of the human population. Finally, we highlight the potential of foodomics and redox proteomics approaches in outlining distinctive molecular pathways and redox protein modifications associated with avenanthramide bioactivities in promoting human health and contrasting the onset and progression of various pathologies. The paper is dedicated to the memory of Adelia Frison.

Abstract
Mast cells (MCs) from human skin have been notoriously resistant to gene manipulation, and a method to knock-down gene expression in in situ differentiated MCs is highly desired. The Dharmacon Accell® transfection system proved successful on several "difficult-to-transfect" cells. In the present work, we therefore tested this method on skin-derived MCs using different siRNA entities. The siRNA was readily taken up, followed by pronounced, specific reduction of gene and protein expression. Hence, we present the first efficient technique for the manipulation of gene expression in primary skin MCs ex vivo, which combines high transfection rates with retained cell viability.
