Cutaneous Pharmacokinetic Approaches to Compare Bioavailability and/or Bioequivalence for Topical Drug Products.

Dermatol Clin 2022 Jul;40(3):319-332

10716 SE Forest View Lane, Happy Valley, OR 97086, USA.

The evaluation of bioequivalence (BE) involves comparing the test product to its reference product in a study whose fundamental scientific principles allow inferring of the clinical performance of the products. Several test methods have been discussed and developed to evaluate topical bioavailability (BA) and BE. Pharmacokinetics-based approaches characterize the rate and extent to which an active ingredient becomes available at or near its site of action in the skin. Read More

Postmarket Assessment for Drugs and Biologics Used in Dermatology and Cutaneous Adverse Drug Reactions.

Dermatol Clin 2022 Jul 2;40(3):265-277. Epub 2022 Jun 2.

Division of Pharmacovigilance, Food and Drug Administration, Center for Drug Evaluation and Research, Office of Surveillance and Epidemiology, 10903 New Hampshire Avenue, Silver Spring, MD 20993, USA.

Postmarket surveillance is critical for the identification of rare safety risks, which are unlikely to be identified during clinical trials and the drug development program. Rare adverse drug reactions with the potential for serious outcomes, including fatalities, include the severe cutaneous adverse reactions of Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms. Dermatologists play an important role in the diagnosis of these serious drug reactions and contribute to drug safety by reporting cases of suspected cutaneous adverse drug reactions. Read More

Human organ rejuvenation by VEGF-A: Lessons from the skin.

Sci Adv 2022 Jun 24;8(25):eabm6756. Epub 2022 Jun 24.

Skin Research Laboratory, Rappaport Faculty of Medicine, Technion - Israel Institute of Technology, Haifa, Israel.

Transplanting aged human skin onto young SCID/beige mice morphologically rejuvenates the xenotransplants. This is accompanied by angiogenesis, epidermal repigmentation, and substantial improvements in key aging-associated biomarkers, including ß-galactosidase, p16, SIRT1, PGC1α, collagen 17A, and MMP1. Angiogenesis- and hypoxia-related pathways, namely, vascular endothelial growth factor A (VEGF-A) and HIF1A, are most up-regulated in rejuvenated human skin. Read More

The Link between Cutaneous Inflammation and Cognitive Impairment.

J Eur Acad Dermatol Venereol 2022 Jun 24. Epub 2022 Jun 24.

Dermatology Hospital, Southern Medical University, Guangdong, 510091, China.

Cognitive impairment is a symptom of neurological disorders, including dementia and Alzheimer's disease; and mild cognitive impairment can be a precursor of both disorders. Aged humans and animal models with other systemic disorders, such as cardiovascular diseases and diabetes, display a higher incidence of cognitive decline. Epidemiological studies have shown that the incidence of cognitive impairment also is higher in subjects with certain inflammatory skin disorders, including psoriasis and chronic eczematous dermatitis.

Inflammation and thrombo-occlusive vessel signalling in benign atrophic papulosis (Köhlmeier-Degos disease).

J Eur Acad Dermatol Venereol 2022 Jun 24. Epub 2022 Jun 24.

Departments of Dermatology, Venereology, Allergology and Immunology, Dessau Medical Center, Medical School Theodor Fontane and Faculty of Health Sciences Brandenburg, Brandenburg, Dessau, Germany.

Background: Although the merely cutaneous, benign form of the extremely rare disease atrophic papulosis (Köhlmeier-Degos disease) may occasionally develop into the systemic, malignant form with time, it is unclear whether it itself exhibits any systemic characteristics.

Objective: To determine whether benign atrophic papulosis exhibits inflammatory and thrombo-occlusive signals and to classify it according to the Chapel-Hill classification of vasculitis.

Methods: In a monocentric, controlled study, levels of cytokines (IL-1β, IL-6, IL-8, IFNγ, MCP-1, VEGF, TNFα, TGF-β1), antiphospholipid antibodies (cardiolipin IgG/A/M, cardiolipin IgG, cardiolipin IgM, β2-glycoprotein IgG/A/M, phosphatidyl choline, phosphatidyl serine, phosphatidyl inositol, phosphatidyl ethanolamine and sphingomyelin A), antibodies against proteinase-3 IgG and myeloperoxidase IgG, antinuclear antibodies and extractable nuclear antigen were assessed in blood samples of six benign atrophic papulosis patients and six age- and sex-matched healthy controls.

A Prospective Multicenter Study to Evaluate the Safety and Efficacy of the Topical Application of MYOWNN™, an Autologous Growth Factor Concentrate (AGFC) Serum, in Anti-Aging.

Cureus 2022 May 21;14(5):e25190. Epub 2022 May 21.

Stem Cell Research, Wockhardt Ltd., Mumbai, IND.

Background Growth factors from platelets have been emerging as a revolutionary treatment with the ability to induce cell growth in the skin, which results in retarding and reversing the aging process. Platelet-rich plasma (PRP) allows for greater release of growth factors and biologically active proteins, which in turn activates the cascade of stimulation of neoangiogenesis and collagen production. PRP is used in anti-aging and facial skin rejuvenation in the form of dermal injections and topical application during micro-needling. Read More

Pharmaceuticals (Basel) 2022 Jun 11;15(6). Epub 2022 Jun 11.

Hematology Unit, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, 20122 Milan, Italy.

Systemic mastocytosis (SM) results from a clonal proliferation of abnormal mast cells (MCs) in extra-cutaneous organs. It could be divided into indolent SM, smoldering SM, SM with an associated hematologic (non-MC lineage) neoplasm, aggressive SM, and mast cell leukemia. SM is generally associated with the presence of a gain-of-function somatic mutation in at codon 816. Read More

Botulinum Toxin Use for Modulating Neuroimmune Cutaneous Activity in Psoriasis.

Medicina (Kaunas) 2022 Jun 16;58(6). Epub 2022 Jun 16.

Department of Physical and Rehabilitation Medicine-"Elias" Emergency University Hospital, "Carol Davila" University of Medicine and Pharmacy, 020021 Bucharest, Romania.

Psoriasis is a complex immune-mediated inflammatory disorder that generates enormous interest within the scientific communities worldwide, with new therapeutic targets being constantly identified and tested. Despite the numerous topical and systemic medications available for the treatment of psoriasis, alternative therapies are still needed for the optimal management of some patients who present with localized, resistant lesions. Novel insights into the contribution of cutaneous neurogenic inflammation in the pathogenesis of psoriasis have yielded exciting new potential roles of nerve-targeting treatments, namely botulinum toxin type A (BoNT-A), for the management of this disease.

State Key Laboratory of Dampness Syndrome of Chinese Medicine, the Second Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou 510120, China.

Psoriasis and skin tumors (such as basal cell carcinoma, squamous cell carcinoma, and melanoma) are chronic diseases that endanger physical and mental health, and yet the causes are largely unknown and treatment options limited. The development of targeted drugs requires a better understanding of the exact pathogenesis of these diseases, and Yes-associated protein (YAP), a member of the Hippo signaling pathway, is believed to play an important role. Psoriasis and skin tumors are characterized by excessive cell proliferation, abnormal differentiation, vasodilation, and proliferation. Read More
