Restoring Adipose Tissue Homeostasis in Response to Aging: Initial Clinical Experience with Profhilo Structura.
Jul,
2023
The aim of the case series was to determine the efficacy of a new medical device developed for adipose tissue restoration in the face. The medical device used the patented NAHYCO Hybrid Technology to deliver 45 mg of high- (1400 ± 200 kDa) and 45 mg of low- (100 ± 20 kDa) molecular-weight hyaluronan, in 2 mL. Patients and methods: Twenty-two volunteers, aged 36-60 years. Two mL of Profhilo Structura was injected using a 25 G cannula for each hemiface, into superficial fat compartment along the line from the preauricular area to the mandibular angle. Two injections were performed, and Profhilo Structura's effect on restoring adipose tissue was evaluated immediately after treatment, and over a 6-month follow-up. The studied medical device revealed a pseudoplastic behavior and consistency that allowed easy extrusion from a syringe. It showed a lower viscosity compared to dermal fillers, based on crosslinked HA. Clinically, the soft tissue thickness increased immediately after injection, and the clinical improvement persisted across a 6-month follow-up. The self-reported satisfaction with the treatment showed an amelioration in the midface of all the subjects enrolled, with no adverse effects. Profhilo Structura demonstrated a peculiar fat compartment integration, with a regenerating effect on adipose tissue senescence. The skin thickening and compaction effects were similar to those obtained using chemically crosslinked dermal fillers, while a natural look was preserved, and the use of crosslinking agents was avoided. read more

Gender-related differences in chronic urticaria.
Oct,
2016
Chronic urticaria (CU) is a common skin disorder with important repercussion on the quality of life (QoL) and a relevant socioeconomic impact. CU is included among the skin diseases that exhibit a significant female preponderance, with an average female to male ratio of nearly 2-4/1. In recent years, an ever-growing interest in gender medicine has been registered and the assessment of gender differences has increasingly become an attractive issue in clinical research. Unfortunately, there are only limited data relative to the study of CU in the perspective of gender medicine. However, apart from the predilection for females, an in-depth evaluation of the available literature shows the existence of other interesting gender-related differences in CU. The aim of this article is to review the current knowledge on gender differences in CU under different points of view, including pathophysiology, epidemiology, clinical and prognostic features, association with comorbidities, psychological aspects and QoL. read more

Prevalence of past and reactivated viral infections and efficacy of cyclosporine A as monotherapy or in combination in patients with psoriatic arthritis--synergy study: a longitudinal observational study.
2014
We have prospectively evaluated psoriatic arthritis (PsA) patients for (1) seropositivity for former viral infections and seroconversion and (2) efficacy of cyclosporine A (CsA) alone or in combination with other immunosuppressants in a time period of 12 months. Screening included HBV antibodies and antigens, HCV antibodies and RNA, HSV 1-2, HZV, EBV, and CMV IgG, and IgM, HHV-6 DNA, and HIV 1-2 antibodies. PsA was evaluated by the Psoriasis Area Severity Index (PASI), the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and the Visual Analogue Scale (VAS). At baseline, 126 (56%) out of 225 evaluable patients had 2 or more seropositivities indicative of former infections, and 31 patients (13.8%) presented seropositivity for HCV, HBV, HSV-1 and -2, HHV-6, EBV, or parvovirus infection; one of them, positive for HBAg, was treated with lamivudine, while the remaining 30 received no specific treatment. None of the 31 patients developed virus reactivation. A reduction (P < 0.001) of PASI, BASDAI, and VAS scores was observed at 6 and 12 months. The treatment of PsA with CsA as monotherapy or in combination was safe and effective. In vitro experiments and clinical findings, including those from our study, suggest that CsA as monotherapy or in combination with biologics might be the treatment of choice in PsA HCV-positive patients. read more

Cyclosporine and herbal supplement interactions.
2014
Cyclosporine (CyA) is a well-known immunosuppressant with a narrow therapeutic window. Its bioavailability is affected by many other traditional drugs and herbal extracts. Cytochrome P-450 isoenzymes CYP3A4 and CYP3A5 and protein P-glycoprotein (P-gp) are involved in CyA bioavailability. Interactions of CyA with herbal extracts are not well known, but, given their increased concomitant use, it is important to know which extracts, many of which are commonly self-prescribed, can affect CyA blood concentrations. Decreased CyA blood concentration has been shown with St John's wort in case reports and, in vivo animal studies, with ginger, liquorice, scutellariae radix, and quercetin. Increased CyA concentration has been reported in patients with grapefruit juice, chamomile, or berberine, and with cannabidiol or resveratrol in animal studies. Effects of Echinacea and Serenoa repens on CyA levels have not been shown consistently, but concomitant use should be avoided. Although findings from animal studies cannot be directly translated into humans, avoiding concomitant use of herbal extracts is prudent until human clinical studies have ruled out any possible interaction. Clinicians should interview their patients carefully about their use of herbal supplements before CyA administration, and those receiving CyA should be warned about possible interactions between herbal preparations and CyA. read more

Cyclosporine regimens in plaque psoriasis: an overview with special emphasis on dose, duration, and old and new treatment approaches.
2013
Cyclosporine A (CsA) is one of the most effective systemic drugs available for the treatment of psoriasis, as evidenced by the results of several randomized studies and by a prolonged experience in dermatological setting. In clinical practice, CsA is usually used for the induction of psoriasis remission at a daily dose included in the range of 2.5-5 mg/kg and with intermittent short-term regimens, lasting on average 3-6 months. The magnitude and rapidity of response are dose dependent, as well as the risk of development of adverse events. Therefore, the dose should be tailored to patient's needs and general characteristics and adjusted during the treatment course according to both the efficacy and tolerability. Some studies support the feasibility of pulse administration of CsA for a few days per week for both the induction and the maintenance of response in psoriasis patients. This paper will review the data on CsA regimens for plaque-type psoriasis and will focus the attention on dose, treatment duration, novel schedules, and role in combination therapies, including the association with biologicals. read more

An Overview of Soft Tissue Fillers for Cosmetic Dermatology: From Filling to Regenerative Medicine.
2021
Hyaluronic acid (HA)-based injectable filling agents are at the forefront of the current demand for noninvasive dermatological procedures for the correction of age-related soft tissue defects. The present review aims to summarize currently available HA-based products and critically appraise their differences in rheological nature and clinical application. Linear HA (LHA) gels may be supplemented with amino acids, lipoic acid, vitamins, nucleosides, or minerals for synergistic antiaging and antioxidant benefits (polycomponent LHA). HA hydrogels can be generated via chemical or physical crosslinking, which increases their elasticity and decreases viscosity. The performance of crosslinked fillers depends on HA concentration, degree of crosslinking, elastic modulus, cohesivity, and type of crosslinking agent employed. PEG-crosslinked LHA displays improved elasticity and resistance to degradation, and lower swelling rates as compared to BDDE-crosslinked LHA. Physical crosslinking stabilizes HA hydrogels without employing exogenous chemical compounds or altering hyaluronans' natural molecular structure. Thermally stabilized hybrid cooperative HA complexes (HCC) are a formulation of high- and low-molecular-weight (H-HA and L-HA) hyaluronans, achieving high HA concentration, low viscosity with optimal tissue diffusion, and a duration comparable to weakly cross-linked gel. Our critical analysis evidences the importance of understanding different fillers' properties to assist physicians in selecting the most appropriate filler for specific uses and for predictable and sustainable results. read more

Safety Assessment of High- and Low-Molecular-Weight Hyaluronans (Profhilo®) as Derived from Worldwide Postmarketing Data.
2020
At present, dermal fillers based on hyaluronic acid (HA) represent the most popular intervention of dermoesthetic medicine for the treatment of skin aging. Recent studies have shown that the combination of HA chains of different lengths and molecular weights improves tissue repair and regeneration through a synergistic mechanism. Profhilo® is a product available that has been on the market since 2015 and is based on stable, hybrid, and cooperative complexes (HyCoCos) produced by means of NAHYCO® Hybrid Technology, which is an innovative thermal process that rules out the use of any chemical reagents. The result is a filler with high biocompatibility and low viscosity that favors optimal diffusion at the tissue level to obtain the target bioremodeling of the facial contour. The objective of this review is to provide data from the overall postmarketing experience after 3 years of use and more than 40,000 patients treated with the medical device. read more

Positive Effects against UV-A Induced Damage and Oxidative Stress on an Cell Model Using a Hyaluronic Acid Based Formulation Containing Amino Acids, Vitamins, and Minerals.
2018
Ultraviolet (UV) radiations are responsible for skin photoaging inducing alteration of the molecular and cellular pathways resulting in dryness and reduction of skin elasticity. In this study, we investigated, , the antiaging and antioxidant effects of hyaluronan formulations based hydrogel. Skinkò E, an intradermic formulation composed of hyaluronic acid (HA), minerals, amino acids, and vitamins, was compared with the sole HA of the same size. For this purpose, HaCaT cells were subjected to UV-A radiations and HO exposure and then treated with growth medium (CTR) combined with M-HA or Skinkò E to evaluate their protective ability against stressful conditions. Cells reparation was evaluated using a scratch model and Time-Lapse Video Microscopy. A significant protective effect for Skinkò E was shown with respect to M-HA. In addition, Skinkò E increased cell reparation. Therefore, NF-kB, SOD-2, and HO-1 were significantly reduced at the transcriptional and protein level. Interestingly, -H2AX and protein damage assay confirmed the protection by hyaluronans tested against oxidative stress. G6pdΔ ES cell line, highly susceptible to oxidative stress, was used as a further cellular model to assess the antioxidant effect of Skinkò E. Western blotting analyses showed that the treatment with this new formulation exerts marked antioxidant action in cells exposed to UV-A and HO. Thus, the protective and reparative properties of Skinkò E make it an interesting tool to treat skin aging. read more

Psoriasis in pregnancy: challenges and solutions.
2015
The available information about the effects of pregnancy on psoriasis and those of psoriasis on pregnancy is almost limited, despite the high frequency of the disease in the general population, as well as in women in reproductive years. Considering the existing evidence, pregnancy does not tend to have a negative influence on psoriasis, as in most women who experience a change in the severity and course of their psoriasis during pregnancy, the change is more likely to be reported as an improvement. This assumption can be applied more convincingly to plaque-type psoriasis, while an exception may be represented by generalized pustular psoriasis, which has been somehow linked to impetigo herpetiformis. Conflicting findings emerged from the few available studies that explored the effect of psoriasis on pregnancy outcomes. Recent studies found an association between moderate-to-severe psoriasis and some pregnancy complications, including pregnancy-induced hypertensive diseases, and have emphasized a trend toward a newborn with low birth weight in patients with psoriasis, especially in those suffering from severe forms. The safety profile during pregnancy is not completely known for many drugs used to treat psoriasis. Moisturizers and low- to moderate-potency topical steroids or ultraviolet B phototherapy represent the first-line therapy for pregnant patients. Many dermatologists may, however, recommend discontinuing all drugs during pregnancy, in consideration of medico-legal issues, and also taking into account that common forms of psoriasis do not compromise the maternal and fetal health. Anyway, for those women whose psoriasis improves during pregnancy, the interruption of any therapy for psoriasis can be a reasonable strategy. The objective of this paper was to review the most relevant literature data on psoriasis in pregnancy, trying to give concurrently practical information about clinical and prognostic aspects, as well as counseling and management. read more
