Vinshtok, Y, Cassuto, D, Belenky, I
Journal of drugs in dermatology : JDD. 2020;(2):170-175
Abstract
Jet Volumetric Remodeling (JVR) utilizes the principle of superficial soft tissue delivery of fluids, such as hyaluronic acid (HA) and other therapeutic materials. Dermal delivery of HA activates fibroblasts increasing collagen and elastin synthesis with a long-lasting dermal remodeling and thickening effect. JVR-injected HA causes immediate and diffuse skin hydration resulting in an aesthetically pleasing aspect. JVR technology is able to target different layers during the same treatment with only minor side effects. The article reviews JVR delivery of hyaluronan in comparison to current skin remodeling treatment modalities. J Drugs Dermatol. 2020;19(2)170-175. doi:10.36849/JDD.2020.3641

Hyaluronan-based delivery of therapeutic oligonucleotides for treatment of human diseases.
Ossipov, DA
Expert opinion on drug delivery. 2019;(6):621-637
Abstract
INTRODUCTION Oligonucleotide therapeutics such as antisense oligonucleotides and siRNA requires chemical modifications and nano-sized carriers to circumvent stability problems in vivo, to reach target tissues, and to overcome tissue and cellular barriers. Hyaluronic acid (HA), already utilized in drug delivery and tissue engineering, possess properties that are useful to solve these problems and achieve full potential of oligonucleotide therapeutics. AREAS COVERED Complexes of oligonucleotide therapeutics with HA are discussed in terms of interactions providing the complexes formation and genes targeted by the therapeutics to cure diseases such as cancer, atherosclerosis, liver cirrhosis, and inflammation. The achieved therapeutic effects are rationalized as consequences of biodistribution, cell internalization and endosomal escape provided by HA. EXPERT OPINION Design of electrostatic, coordination, and hydrophobic interactions as well as covalent conjugation between oligonucleotide drugs, HA macromolecules and intermediate ligands are crucial for carrier-cargo association and dissociation under different conditions to impart oligonucleotides stability in vivo, their accumulation in diseased organs, cellular uptake, and dissociation in cytoplasm intact. These are the delivery factors that provides eventual complex formation of oligonucleotide therapeutics with their mRNA, microRNA, or protein targets. Elucidation of the impact of structural parameters of oligonucleotide/HA complexes on their therapeutic effect in vivo is important for the future rational design of the delivery agents.

Salsberg, J, Andriessen, A, Abdulla, S, Ahluwalia, R, Beecker, J, Sander, M, Schachter, J
Journal of cosmetic dermatology. 2019;(3):815-820
Abstract
BACKGROUND The skin exposome refers to the constellation of external exposures that contribute to cutaneous aging, including solar radiation, air pollution, tobacco smoke, unbalanced nutrition, and cosmetic products. This review explores the skin exposome and the role of a combination hyaluronic acid and mineralized thermal water product used to restore and maintain optimal skin barrier function. METHOD An expert panel of 7 dermatologists who treat clinical signs of facial aging convened for a one-day meeting to discuss the results of a literature review on the skin exposome and the role of M89, a mineralized thermal water and hyaluronic acid-based gel, to improve the quality of facial skin. Evidence coupled with expert opinion and experience of the panel was used to address clinical challenges in the treatment of photo-aging, and the use of M89. RESULTS Solar radiation (ultraviolet radiation, visible light, and infrared radiation), air pollution, tobacco smoke, nutrition, and miscellaneous factors, including stress, sleep deprivation, and temperature, may potentiate skin aging by triggering molecular processes that damage skin structure. M89 was developed to maintain and restore skin and contains ingredients to aid physical, hydric, antioxidant, and antimicrobial skin barrier function. CONCLUSIONS Increasing knowledge of the exposome and microenvironment contributing to skin aging may support a better understanding of measures to support the skin. The initial results of in vitro and clinical studies of M89 show its potential to improve skin barrier function.

Marcuzzo, AV, Tofanelli, M, Boscolo Nata, F, Gatto, A, Tirelli, G
APMIS : acta pathologica, microbiologica, et immunologica Scandinavica. 2017;(9):763-772
Abstract
Bacterial resistance is a growing phenomenon which led the scientific community to search for new therapeutic targets, such as biofilm. A bacterial biofilm is a surface-associated agglomerate of microorganisms embedded in a self-produced extracellular polymeric matrix made of polysaccharides, nucleic acids, and proteins. Scientific literature offers several reports on a biofilm's role in infections regarding various body districts. The presence of a bacterial biofilm is responsible for poor efficacy of antibiotic therapies along with bacterial infections in ear, nose, and throat (ENT) districts such as the oral cavity, ear, nasal cavities, and nasal sinuses. In particular, bacterial biofilms are associated with recalcitrant and symptomatically more severe forms of chronic rhinosinusitis. As of today, there are no therapeutic options for the eradication of bacterial biofilm in ENT districts. Hyaluronic acid is a glycosaminoglycan composed of glucuronic acid and N-acetylglucosamine disaccharide units. Its efficacy in treating rhinosinusitis, whether or not associated with polyposis, is well documented, as well as results from its effects on mucociliary clearance, free radical production and mucosal repair. This review's aim is to evaluate the role of bacterial biofilms and the action exerted on it by hyaluronic acid in ENT pathology, with particular attention to the rhinosinusal district. In conclusion, this paper underlines how the efficacy of hyaluronate as an anti-bacterial biofilm agent is well demonstrated by in vitro studies; it is, however, only preliminarily demonstrated by clinical studies.

Pazin, C, de Souza Mitidieri, AM, Silva, AP, Gurian, MB, Poli-Neto, OB, Rosa-E-Silva, JC
International urogynecology journal. 2016;(5):697-708
Abstract
INTRODUCTION AND HYPOTHESIS Bladder pain syndrome/interstitial cystitis (BPS/IC) has various treatments; however, no standardized treatment has been established. The aim was to analyze different types of treatment of BPS/IC and their effectiveness. METHODS A literature review with a search strategy for articles related to BPS/IC published between 1990 and 2014 was conducted on MEDLINE, PUBMED, and SCOPUS. Only randomized controlled trials in women were included in the meta-analysis, while other experimental studies were used as bases for a systematic review of the topic. Clinical trial quality was defined according to the Jadad scale. RESULTS Of 356 articles, 13 were included in the analysis. The intervention methods were as follows: instillation of hyaluronic acid, botulinum toxin A, intravesical lidocaine, hyperbaric chamber, massage, physiotherapy, phosphate-buffered saline, piroxicam in combination with doxepin, and others. We did not find any treatment with at least two randomized controlled trials for meta-analysis. Among the assessment tools for symptoms of BPS/IC, the most frequently used were the visual analogue scale, voiding record, and the O'Leary-Sant questionnaire. CONCLUSION Existing studies were not able to define the best approach for the treatment of BPS/IC. The lack of standardized treatment may be related to the diversity of interventions used; therefore, further studies with better methodological quality are needed.

Casale, M, Vella, P, Moffa, A, Oliveto, G, Sabatino, L, Grimaldi, V, Ferrara, P, Salvinelli, F
International journal of pediatric otorhinolaryngology. 2016;:22-6
Abstract
BACKGROUND Inflammatory disease of upper airway in pediatric population represents a social problem for both the pharmaco-economic impact and a burden for the family. To date, the use of topical therapies represents a significant therapeutic progress because they are able to reduce mucosal inflammation and improve tissue healing. Topical Hyaluronic Acid (HA) is a promising molecule that has been recently proposed as adjuvant treatment in the inflammatory disease of the upper aerodigestive tract (UADT) infections. AIMS The aim of our work was to review the published literature regarding all the potential therapeutic effects of HA in the inflammatory disease of upper airway in pediatric population and evaluate the effectiveness of HA, alone or in combination, in children affected by cystic fibrosis. METHODS Relevant published studies about use of HA in UADT in pediatrics were searched in Pubmed, Google Scholar, Ovid using various keywords with no limit for the year of publication. Studies based on the use of HA with nasal packing and with invasive administration of HA were excluded. RESULTS At the end of our selection process, four publications have been included: one of them in children with recurrent upper respiratory tract infections, one of them in children with bacterial acute rhinopharyngitis, two of them in children affected by cystic fibrosis. CONCLUSIONS Topical administration of HA plays a pivotal role in all the children suffering from UADT inflammatory disease, and positive results are generally observed in children with cystic fibrosis.

Abstract
Striae distensae (SD) are common dermal lesions, with significant physical and psychological impact. Many therapeutic modalities are available but none can completely eradicate SD. The most common therapy is the application of topicals used both therapeutically and prophylactically. Even though there are many commercially available topical products, not all have sufficient level of evidence to support their continued use in SD. The aim here was to assess the evidence for the use of topicals in SD and to propose a structured approach in managing SD. A systematic search of published literature and manufacturer website information for topicals in SD was carried out. The results showed that there are few studies (n = 11) which investigate the efficacy of topicals in management of SD. Trofolastin and Alphastria creams demonstrated level-2 evidence of positive results for their prophylactic use in SD. Additionally, tretinoin used therapeutically showed varying results whilst cocoa butter and olive oil did not demonstrate any effect. Overall, there is a distinct lack of evidence for each topical formulation. The majority of topicals failed to mention their effect on early vs. later stages of SD (striae rubrae compared to striae albae) and their role in both prevention and treatment. In conclusion, there is no topical formulation, which is shown to be most effective in eradicating or improving SD. A structured approach in identification and targeted management of symptoms and signs with the appropriate topical is required. Randomized controlled trials are necessary to assess the efficacy of topical products for treatment and prevention of different stages of SD.

Hyaluronan's Role in Fibrosis: A Pathogenic Factor or a Passive Player?
Albeiroti, S, Soroosh, A, de la Motte, CA
BioMed research international. 2015;:790203
Abstract
Fibrosis is a debilitating condition that can lead to impairment of the affected organ's function. Excessive deposition of extracellular matrix (ECM) molecules is characteristic of most fibrotic tissues. Fibroblasts activated by cytokines or growth factors differentiate into myofibroblasts that drive fibrosis by depositing ECM molecules, such as collagen, fibronectin, and connective tissue growth factor. Transforming growth factor-β (TGF-β) is one of the major profibrotic cytokines which promotes fibrosis by signaling abnormal ECM regulation. Hyaluronan (HA) is a major ECM glycosaminoglycan that is regulated by TGF-β and whose role in fibrosis is emerging. Aside from its role as a hydrating, space filling polymer, HA regulates different cellular functions and is known to have a role in wound healing and inflammation. Importantly, HA deposition is increased in multiple fibrotic diseases. In this review we highlight studies that link HA to fibrosis and discuss what is known about the role of HA, its receptors, and its anabolic and catabolic enzymes in different fibrotic diseases.

Tripodo, G, Trapani, A, Torre, ML, Giammona, G, Trapani, G, Mandracchia, D
European journal of pharmaceutics and biopharmaceutics : official journal of Arbeitsgemeinschaft fur Pharmazeutische Verfahrenstechnik e.V. 2015;(Pt B):400-16
Abstract
Hyaluronic acid (HA) is a biodegradable, biocompatible, nontoxic, and non-immunogenic glycosaminoglycan used for various biomedical applications. The interaction of HA with the CD44 receptor, whose expression is elevated on the surface of many types of tumor cells, makes this polymer a promising candidate for intracellular delivery of imaging and anticancer agents exploiting a receptor-mediated active targeting strategy. Therefore, HA and its derivatives have been most investigated for the development of several carrier systems intended for cancer diagnosis and therapy. Nonetheless, different and important delivery applications of the polysaccharide have also been described, including gene and peptide/protein drugs delivery. The aim of this review was to provide an overview of the existing recent literature on the use of HA and its derivatives for drug delivery and imaging. Notable attention is given to nanotheranostic systems obtained after conjugation of HA to nanocarriers as quantum dots, carbon nanotubes and graphene. Meanwhile, attention is also paid to some challenging aspects that need to be addressed in order to allow translation of preclinical models based on HA and its derivatives for drug delivery and imaging purposes to clinical testing and further their development.
