Acne Vulgaris-Novel Treatment Options and Factors Affecting Therapy Adherence: A Narrative Review

Platelet rich plasma use for treatment of acne scars: an overview of systematic reviews

BACKGROUND

A reappraisal of the conclusions of systematic reviews (SRs) and meta-analyses validity related to Platelet-rich plasma (PRP), alone or in combination with other treatments, compared to regimens PRP-free for the treatment of acne scars.

MATERIALS AND METHODS

An overview of SRs. The methodological quality of the reviews was assessed using AMSTAR-2 checklist; quality of the evidence of primary studies was appraised following the GRADE approach.

RESULTS

Fifteen SRs were included in this overview. Data were from 124 overlapping reports, based on 34 individual primary studies (10 parallel arm randomized trials, 21 split-face studies, and 3 uncontrolled studies). Most of the studies evaluated combination of PRP with microneedling or with laser therapy compared to microneedling or laser therapy without PRP. Clinical improvement (reported as degree of improvement or improvement score) and patient's satisfaction rate were significantly higher in PRP recipients compared to controls. Crusting time and duration of erythema were significantly shorter in PRP recipients compared to controls. Most of the reviews considered in this overview can be considered of low methodological quality due to the fact that several critical methodological requirements of AMSTAR-2 checklist were unmet or partially met; only 6 of the 15 reviews incorporated study quality in their conclusions, and no GRADE assessment was performed for the reported outcomes in any of the SRs. With the GRADE approach, the quality of the evidence for the outcomes analysed ranged from very low to low due to risk of bias in the primary studies, inconsistency between the studies, and imprecision.

DISCUSSION

The low or very low certainty of evidence does not support clear clinical decision about the PRP use in combination with microneedling or laser therapy for the treatment of acne scars. Further well-designed studies are required to improve the evidence base for PRP combination therapy for acne scars.

Descriptive analysis on disproportionate medication errors and associated patient characteristics in the Food and Drug Administration's Adverse Event Reporting System

BACKGROUND

Medication errors (MEs) are a major public health concern which can cause harm and financial burden within the healthcare system. Characterizing MEs is crucial to develop strategies to mitigate MEs in the future.

OBJECTIVES

To characterize ME-associated reports, and investigate signals of disproportionate reporting (SDRs) on MEs in the Food and Drug Administration's Adverse Event Reporting System (FAERS).

METHODS

FAERS data from 2004 to 2020 was used. ME reports were identified with the narrow Standardised Medical Dictionary for Regulatory Activities® (MedDRA®) Query (SMQ) for MEs. Drug names were converted to the Anatomical Therapeutic Chemical (ATC) classification. SDRs were investigated using the reporting odds ratio (ROR).

RESULTS

In total 488 470 ME reports were identified, mostly (59%) submitted by consumers and mainly (55%) associated with females. Median age at time of ME was 57 years (interquartile range: 37-70 years). Approximately 1 out of 3 reports stated a serious health outcome. The most prevalent reported drug class was "antineoplastic and immunomodulating agents" (25%). The most common ME type was "incorrect dose administered" (9%). Of the 1659 SDRs obtained, adalimumab was the most common drug associated with MEs, noting a ROR of 1.22 (95% confidence interval: 1.21-1.24).

CONCLUSION

This study offers a first of its kind characterization of MEs as reported to FAERS. Reported MEs are frequent and may be associated with serious health outcomes. This FAERS data provides insights on ME prevention and offers possibilities for additional in-depth analyses.

Fresh Baked: An Overview of Newly FDA-Approved Drugs for Dermatological Usage

With our better understanding of the pathogenesis of various diseases, more and more drugs and biological products are being tried and tested every day. Roughly, around 40-50 novel drugs get approved by the Food and Drug Administration (FDA) for use in the general population, making it difficult for a physician to keep track of the constant changes in therapy. This article aimed to provide a compilation of all the FDA-approved new drugs for dermatological conditions and new dermatological indications of known drugs in the recent past, especially for dermatology residents and practising dermatologists. A comprehensive analysis, based on the list of new molecular entities approved by the FDA from 2020 to 2023, as well as a thorough English language literature search from 2020 to July 2023 across multiple databases (PubMed, MEDLINE, Springer Nature, Google Scholar and Cochrane) for various keywords (alone and in combination) such as "FDA approved" OR "recent advances in therapy" OR "recent drugs" OR "novel treatment" OR "dermatology," was performed. All data extracted were incorporated into the present compilation. A total of 33 drugs, including newly approved and newly approved indications of previously known drugs, were found. Relevant information about them has been discussed in a tabulated manner. This article provides an at a glance summarised profile of the newly FDA-approved drugs, as available in the existing literature. However, with the astonishing rate of new drugs hitting the market, more and more clinical trials are required to ensure the rational use of these agents.

Curcumin/Fusidic Acid Bitherapy Loaded Mixed Micellar Nanogel for Acne Vulgaris Treatment: In Vitro and In Vivo Studies

The combination of herbal drugs with a topical antibacterial for managing a chronic disease like acne vulgaris has emerged lately to settle side effects and bacterial multidrug resistance. Mixed micelles (MMs) incorporated into nanogel were explored for hybrid delivery of curcumin (Cur) and fusidic acid (FA) combination presenting a multi-strategic treatment. Curcumin-fusidic acid-loaded mixed micelles (Cur-FA-MMs) were assessed for size, surface charge, compatibility, in vitro release, and encapsulation. The selected formula was further loaded into nanogel and investigated for viscosity, ex vivo permeation, and in vivo potential. Cur-FA-MMs exhibited uniform nanosized spherical morphology, and negative surface charge affording high encapsulation for both drugs with a biphasic in vitro release over a period of 48h and good colloidal stability. The attained Cur-FA-MM-loaded nanogel had optimum viscosity with remarkable permeation coefficient values nearly 2-fold that related to plain nanogel. The pharmacodynamic effect of Cur on FA was pronounced by the significant improvement of the skin's degree of inflammation, epidermal hypertrophy, and congestion in animals treated with Cur-FA-MM-loaded nanogel. In conclusion, micellar nanogel could enable the progressive effect of Cur (an antioxidant with reported antibiotic activity) on FA (antibiotic) and decrease the risk of emerging antibiotic resistance by enhancing the solubility and permeation of Cur.

The Effectiveness of Pyruvic Acid Peeling in Improving the Quality of Life of Patients with Acne Vulgaris

Improving the quality of life (QoL) of patients with various chronic diseases has become a challenge and priority of contemporary medicine. The aim of this study was to assess the impact of pyruvic acid peeling on the QoL of patients with acne vulgaris. The study group consisted of 200 young patients (mean age 23.04 ± 4.71) with acne vulgaris of mainly mild or moderate severity. Basic data about the patient were collected using a self-reported questionnaire. The assessment of QoL was carried out using standardized questionnaires: CADI (Cardiff Acne Disability Index), DLQI (Dermatology Life Quality Index), SWLS (Satisfaction With Life Scale), and BDI (Beck Depression Inventory). The cosmetic intervention consisted of chemical peeling with 35% pyruvic acid for acne lesions on the body and included four series repeated at 7-day intervals. This study demonstrated that acne vulgaris impairs the quality of life of young people. There were no significant differences between the severity of acne and the lifestyles of the subjects. The applied cosmetic procedure significantly decreased the severity of the acne and improved the quality of life of the patients.

Efficacy of Oxybrasion and Cosmetic Acids on Selected Skin Parameters in the Treatment with Acne Vulgaris

Purpose

The present study aimed to evaluate the efficacy of an oxybrasion treatment applied alone and an oxybrasion treatment combined with cosmetic acids in improving acne-prone skin and selected skin parameters.

Patients and Methods

A single-blind placebo study in a sample of 44 women diagnosed with acne vulgaris was conducted. Group A (n = 22) had a series of five oxybrasion treatments, while group B (n = 22) received a synergy of five oxybrasion treatments and a mixture of phytic, pyruvic, and lactic and lactic ferulic acids at 40% pH 1.4. Cosmetic treatments were performed every 14 days, and The Derma Unit SCC3 apparatus (Courage & Khazaka, Cologne, Germany) Sebumeter SM 815 and Corneometer CM825 and GAGS scale were used to check their effectiveness.

Results

A Bonferroni post hoc test showed that group A and B did not differ from each other in acne severity before treatment (p = 1.00). However, these samples differed significantly after treatment (p < 0.001), suggesting that combined treatment of oxybrasion and cosmetic acids has a better effect than oxybrasion alone. Also, two treatment conditions (before and after) were statistically different for groups A and B separately (p < 0.001), indicating a similar efficacy of both treatments on acne severity.

Conclusion

Cosmetic treatments improved acne-prone skin and selected skin parameters. Better results were obtained by combining an oxybrasion treatment with cosmetic acids.

Clinical Trial Approval

The clinical trial with ID ISRCTN 28257448 approved this study.

Comparative Evaluation of Existing and Rationally Designed Novel Antimicrobial Peptides for Treatment of Skin and Soft Tissue Infections

Skin and soft tissue infections (SSTIs) and acne are among the most common skin conditions in primary care. SSTIs caused by ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter sp.) can range in severity, and treating them is becoming increasingly challenging due to the growing number of antibiotic-resistant pathogens. There is also a rise in antibiotic-resistant strains of Cutibacterium acne, which plays a role in the development of acne. Antimicrobial peptides (AMPs) are considered to be a promising solution to the challenges posed by antibiotic resistance. In this study, six new AMPs were rationally designed and compared to five existing peptides. The MIC values against E. coli, P. aeruginosa, K. pneumoniae, E. faecium, S. aureus, and C. acnes were determined, and the peptides were evaluated for cytotoxicity using Balb/c 3T3 cells and dermal fibroblasts, as well as for hemolytic activity. The interaction with bacterial membranes and the effect on TNF-α and IL-10 secretion were also evaluated for selected peptides. Of the tested peptides, RP556 showed high broad-spectrum antibacterial activity without inducing cytotoxicity or hemolysis, and it stimulated the production of IL-10 in LPS-stimulated peripheral blood mononuclear cells. Four of the novel AMPs showed pronounced specificity against C. acnes, with MIC values (0.3–0.5 μg/mL) below the concentrations that were cytotoxic or hemolytic.
