Biosignatures of defective sebaceous gland activity in sebum-rich and sebum-poor skin areas in adult atopic dermatitis

Atopic dermatitis (AD) is a composite disease presenting disruption of the skin permeability barrier (SPB) in the stratum corneum (SC). Recent evidence supports derangement of the sebaceous gland (SG) activity in the AD pathomechanisms. The objective of this study was to delineate profiles of both sebaceous and epidermal lipids and of aminoacids from SG-rich (SGR) and SG-poor (SGP) areas in AD. Both sebum and SC were sampled from SGR areas, while SC was sampled also from SGP areas in 54 adult patients with AD, consisting of 34 and 20 subjects, respectively with and without clinical involvement of face, and in 44 age and sex-matched controls. Skin biophysics were assessed in all sampling sites. Disruption of the SBP was found to be associated with dysregulated lipidome. Abundance of sapienate and lignocerate, representing, respectively, sebum and the SC type lipids, were decreased in sebum and SC from both SGR and SGP areas. Analogously, squalene was significantly diminished in AD, regardless the site. Extent of lipid derangement in SGR areas was correlated with the AD severity. The abundance of aminoacids in the SC from SGR areas was altered more than that determined in SGP areas. Several gender-related differences were found in both controls and AD subgroups. In conclusion, the SG activity was differently compromised in adult females and males with AD, in both SGR and SGP areas. In AD, alterations in the aminoacidome profiles were apparent in the SGR areas. Lipid signatures in association with aminoacidome and skin physical properties may serve the definition of phenotype clusters that associate with AD severity and gender.

Analysis of predictive factors influencing dupilumab continuation rate in adult patients with atopic dermatitis: results from an Italian multicenter study

OBJECTIVES

The purpose of this study was to analyze the drug survival rate of dupilumab up to 2 years in a large real-world cohort of adult patients affected by moderate/severe atopic dermatitis (AD), and to investigate the clinical, demographic and predictive factors influencing the patients' treatment persistence.

MATERIAL AND METHODS

This study included adult patients affected by moderate-to-severe AD treated with dupilumab for at least 16 weeks who visited 7 dermatologic outpatient clinics in Lazio, Italy, from January 2019 until August 2021.

RESULTS

A total of 659 adult patients (345 male [52.3%], mean age: 42.8 years) with an average treatment duration of 23.3 months were enrolled in the study. Overall, 88.6% and 76.1% of patients were still on treatment after 12 and 24 months, respectively. The drug survival rate for discontinuation due to AEs and dupilumab ineffectiveness was 95.0% at 12 months and 90.0% at 24 months. The main reasons for drug discontinuation included inefficacy (29.6%), failed compliance (17.4%), persistent efficacy (20.4%) and adverse events (7.8%). Adult AD onset (≥18 years) and EASI score severity measured at the last follow-up visit were the only factors significantly associated with lower drug survival.

CONCLUSION

This study revealed an increased cumulative probability of dupilumab survival at 2 years, reflected by a sustained effectiveness and a favorable safety profile of the drug.

Drug survival analysis of dupilumab and cyclosporin in patients with atopic dermatitis: a multicentre study

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a prevalence of about 2%-10% in the adult.Cyclosporin is a traditional immunosuppressive drug efficacious for treating AD, but its use is limited by several adverse event. Dupilumab is a monoclonal antibody blocking the effects of both of interleukin (IL)-4 and IL-13, pivotal cytokines in the pathogenesis of atopic diseases.For chronic conditions, such as AD, the efficacy and safety of a drug can be evaluated by drug survival (DS) analysis which gives a reflection of daily practice by evaluating the time from initiation to discontinuation of therapy.This study provides a comparative survival analysis between the only 2 drugs approved in Italy for the treatment of moderate-to-severe AD, cyclospoorin and dupilumab.

COVID-19 vaccines in adult cancer patients with solid tumours undergoing active treatment: Seropositivity and safety. A prospective observational study in Italy

INTRODUCTION

Patients with cancer are presumed a frail group at high risk of contracting coronavirus disease (COVID-19), and vaccination represents a cornerstone in addressing the COVID-19 pandemic. However, data on COVID-19 vaccination in cancer patients are fragmentary and poor.

METHODS

An observational study was conducted to evaluate the seropositivity rate and safety of a two-dose regimen of the BNT162b2 or messenger RNA-1273 vaccine in adult patients with solid cancer undergoing active anticancer treatment or whose treatment had been terminated within 6 months of the start of the study. The control group was composed of healthy volunteers. Serum samples were evaluated for SARS-COV-2 antibodies before vaccinations and 2-6 weeks after the administration of the second vaccine dose. Primary end-point: seropositivity rate. Secondary end-points: safety, factors influencing seroconversion, IgG titers of patients versus healthy volunteers, COVID-19 infection.

RESULTS

Between 20th March 2021 and 12th June 2021, 293 consecutive patients with cancer-solid tumours underwent a program of COVID-19 vaccinations; of these, 2 patients refused vaccination, 13 patients did not receive the second dose of the vaccine because of cancer progression, and 21 patients had COVID-19 antibodies at baseline and were excluded. The 257 evaluable patients had a median age of 65 years (range 28-86), 66.15% with metastatic disease. Primary end-point: seropositivity rate in patients was 75.88% versus 100% in the control group. Secondary end-points: no Grade 3-4 side-effects, no COVID-19 infections were reported. Patients median IgG titer was significantly lower than in the control group; male sex and active anticancer therapy influenced negative seroconversion. BNT162b2 or messenger RNA-1273 vaccines were immunogenic in cancer patients, showing good safety profile.

P–558 SNP array versus karyotype for prenatal diagnosis in fetuses with abnormal ultrasound: a systematic review and meta-analysis

Study question

Does Single nucleotide polymorphism (SNP) array provide a diagnostic advantage over conventional karyotype in prenatal diagnosis for fetuses with an abnormal ultrasound?

Summary answer

SNP array in the prenatal setting provides an incremental diagnostic yield over karyotype and the diagnostic accuracy is comparable with combined SNP array and karyotype

What is known already

Single nucleotide polymorphism and comparative genomic hybridization based arrays (aCGH) are the two chromosomal microarray (CMA) platforms available. Guidelines which recommend offering CMA instead of karyotyping for prenatal diagnosis are mainly based on studies that compared aCGH with karyotype. There is a paucity of reviews that critically appraise the role of SNP array as a prenatal diagnostic tool. We decided to estimate the incremental yield of SNP array over karyotype in detecting chromosomal abnormalities, and to determine the diagnostic accuracy of SNP alone compared with SNP array and karyotype in combination for prenatal diagnosis in fetuses with an abnormal ultrasound.

Study design, size, duration

We conducted a systematic review of studies comparing SNP array with karyotype for prenatal diagnosis in fetuses with an abnormal ultrasound. We performed a literature search in the electronic databases of EMBASE, PubMed, CENTRAL, CDSR, SCOPUS and Web of science for relevant studies published in the English language between January1996 and May 2020. We also hand searched the referenced list of included studies and performed a google search for grey literature to identify potential studies.

Participants/materials, setting, methods

The study population was women undergoing prenatal diagnosis for abnormal fetal ultrasound. Studies in which SNP array and karyotyping had been used in fetuses with abnormal ultrasound and which allowed for a 2 x 2 data extraction table were included. We estimated the incremental yields for SNP array over karyotype. For determining the diagnostic accuracy, we considered SNP array alone as the index test and combined karyotype & SNP array as the reference standard.

Main results and the role of chance

We included six studies for quantitative analysis. After pooling results, incremental yield of SNP array over normal karyotype was 10% (95% confidence interval, CI 4 to 16%) in fetuses with abnormal ultrasound while incremental yield of karyotype over SNP array was 1% (95% CI 0 to 2%). The agreement between SNP array and karyotype was 92%. Variant of uncertain significance (VUS) rates ranged from 4–8%.

For SNP array alone versus combined SNP array and conventional karyotype, pooled sensitivity and specificity was 0.96 (95% CI 0.91 to 0.99) and 1.00 (95% CI 0.99 to 1.00) respectively. The Area under curve (AUC) was 0.99 indicating the discriminating ability of the SNP array was very high to identify the fetus with chromosomal abnormalities.

Limitations, reasons for caution

Only studies published in English were included. There was some degree of heterogeneity in inclusion criteria for the included studies.

Wider implications of the findings: The current study suggests SNP array alone can replace conventional karyotype for prenatal diagnosis in fetus with an abnormal ultrasound. Limitations to adoption of SNP testing might include the requirement of requisite expertise to interpret the results and counsel patients appropriately, especially with the propensity of SNPs to identify VUS.

Effects of food supplements and a topical solution containing nanosilicon on skin hydration, barrier function, and elasticity

BACKGROUND

Silicon is an abundant element in the human body and plays an important role in the skin, taking part in the synthesis of collagen and glycosaminoglycans. The use of nanotechnology methods, which processes materials at an atomic and molecular scale, has allowed the development of nanosilicons.

AIMS

The study evaluates the effectiveness of a food supplement and a topical solution containing nanosilicon in improving skin hydration and elasticity.

METHODS

A total of 30 female subjects were randomized to receive the placebo (n = 15) and the active compound (n = 15). All enrolled subjects took the food supplement twice a day for 20 days and then once a day for the next 20 days, and they also had to apply the nanosilicon solution on the right forearm four times a day. Evaluation of several parameters was performed after 20 and 40 days through the use of non-invasive instrumental methods (Corneometer^® CM 825, Cutometer^® MPA 580, Visioscan^® VC, Tewameter^® TM 200).

RESULTS

Both treatment groups showed a statistically significant improvement in barrier function and in skin hydration on the right forearm after 20 days; increase in skin elasticity was observed only in the group taking the active compound.

CONCLUSIONS

The study showed that the administration of a food supplement and a topical solution, both containing nanosilicon, improves hydration, elasticity, and skin barrier function.

Instrumental evaluation of skin barrier function and clinical outcomes during dupilumab treatment for atopic dermatitis: An observational study

BACKGROUND

Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by pruritus, xerosis, and skin barrier dysfunction. Skin barrier alteration is associated with an increase in trans-epidermal water loss (TEWL) and reduction in skin hydration. Dupilumab is a monoclonal antibody targeting interleukin-13 modulating pro-inflammatory signal transduction, which has been approved for moderate to severe AD. The aim of this study is to evaluate the effects of Dupilumab on skin barrier functions, using non-invasive instruments and clinical evaluation.

MATERIALS AND METHODS

Thirty patients affected by moderate-severe AD, who had been administered dupilumab, were evaluated by clinical examination and through the instrumental measurements of TEWL and corneometry at the baseline (T0) and 8 weeks (T1) on lesional skin. The clinical evaluation was performed using the Eczema Area and Severity Index (EASI) score. Moreover, a Dermatology Life Quality Index (DLQI) and 7-day numeric rating scale (NRS) questionnaires were administered to each patient.

RESULTS

The instrumental parameters of skin barrier recovery confirmed the clinical improvement outcomes with a statistically significant reduction of TEWL at T1.

CONCLUSION

Our data confirm the clinical outcomes already reported in the literature and show that there was an inverse proportional correlation between TEWL levels and clinical severity after 8 weeks of treatment with dupilumab.

Ribociclib-Induced Erythema Dyschromicum Perstans (Ashy Dermatosis)-Like Pigmentation in a Metastatic Breast Cancer Patient

Ribociclib is a selective cyclin-dependent kinase (CDK) 4/6 inhibitor that has been approved in combination with endocrine therapy for the treatment of hormone receptor-positive/human epidermal growth factor 2-negative advanced or metastatic breast cancer. The main dermatological adverse events associated with CDK 4/6 inhibitors that are described in the literature include skin rash, an increased risk of alopecia, and stomatitis. Erythema dyschromicum perstans (EDP), also known as ashy dermatosis, is characterized by acquired small and large slate-gray hyperpigmented macules with erythematous borders. There are currently no published reports of EDP-like or pigmentary changes induced by CDK 4/6 inhibitors. This report describes the first case of EDP-like pigmentation associated with ribociclib therapy.

IDseq-An open source cloud-based pipeline and analysis service for metagenomic pathogen detection and monitoring

BACKGROUND

Metagenomic next-generation sequencing (mNGS) has enabled the rapid, unbiased detection and identification of microbes without pathogen-specific reagents, culturing, or a priori knowledge of the microbial landscape. mNGS data analysis requires a series of computationally intensive processing steps to accurately determine the microbial composition of a sample. Existing mNGS data analysis tools typically require bioinformatics expertise and access to local server-class hardware resources. For many research laboratories, this presents an obstacle, especially in resource-limited environments.

FINDINGS

We present IDseq, an open source cloud-based metagenomics pipeline and service for global pathogen detection and monitoring (https://idseq.net). The IDseq Portal accepts raw mNGS data, performs host and quality filtration steps, then executes an assembly-based alignment pipeline, which results in the assignment of reads and contigs to taxonomic categories. The taxonomic relative abundances are reported and visualized in an easy-to-use web application to facilitate data interpretation and hypothesis generation. Furthermore, IDseq supports environmental background model generation and automatic internal spike-in control recognition, providing statistics that are critical for data interpretation. IDseq was designed with the specific intent of detecting novel pathogens. Here, we benchmark novel virus detection capability using both synthetically evolved viral sequences and real-world samples, including IDseq analysis of a nasopharyngeal swab sample acquired and processed locally in Cambodia from a tourist from Wuhan, China, infected with the recently emergent SARS-CoV-2.

CONCLUSION

The IDseq Portal reduces the barrier to entry for mNGS data analysis and enables bench scientists, clinicians, and bioinformaticians to gain insight from mNGS datasets for both known and novel pathogens.

Melasma: How hormones can modulate skin pigmentation

We described-along with a genetic predisposition and exposure to sunlight, as the main factors for melasma development-pregnancy, hormonal therapies, and oral contraceptive pills. Whilst hormonal alteration or therapies are frequently reported in literature in association with melasma, studies analyzing the laboratoristic correlation are limited. We review data published on hormones variations both in women and males with melasma and report some peculiar clinical cases that further demonstrate how the relationship between hormone secretion and melasma development is difficult to be defined.

Efficacy of a shower cream and a lotion with skin-identical lipids in healthy subjects with atopic dry skin

BACKGROUND

Atopic dermatitis is a chronic, pruritic inflammatory skin disease that adversely affects quality of life.

AIMS

The current study evaluates the efficacy of a shower cream and a lotion, each with skin-identical lipids and emollients, in the treatment of atopic dry skin of subjects with a history of atopic condition.

METHODS

In all, 40 healthy females with clinically dry skin on the lower legs were enrolled in the study and underwent 4 weeks of daily use of the shower cream and 2 additional weeks of both the shower cream and the body lotion. Subjects were evaluated at day 0, week 4, and week 6. Skin barrier function was assessed by Tewameter^® , skin hydration by Corneometer^® , smoothness and desquamation by Visioscan^® , and stratum corneum architecture by reflectance confocal microscopy (RCM). The investigator assessed the degree of dryness, roughness, redness, cracks, tingling and itch, and subjective self-assessment evaluated the perception of skin soothing, smoothness, and softness.

RESULTS

Skin barrier function and skin moisture maintenance were significantly improved using the shower cream. The lotion with physiological lipids, together with the shower cream, also improved skin barrier function and moisture. Both the shower cream and the body lotion reduced clinical dryness, roughness, redness, cracks, tingling and itch, according to the dermatologist, and increased soothing, smoothness, and softness, according to the subjects of the study.

CONCLUSION

The combination of a shower cream and a lotion with physiological lipids efficiently restores skin barrier function and increases skin hydration, becoming an effective skin-care option for patients with atopic dry skin.

Diet: the keystone of autism spectrum disorder?

Children with autism are characterized by an impairment of social interaction and repetitive patterns of behaviour. Autism is a heterogeneous span of disorders with unknown aetiology. Research has grown significantly and has suggested that environmental risk factors acting during the prenatal period could influence the neurodevelopment of offspring. The literature suggests that the maternal diet during pregnancy has a fundamental role in the etiopathogenesis of autism. Indeed, a maternal diet that is high in some nutrients has been associated with an increase or reduction in the risk of develop Autism Spectrum Disorders (ASD). The diet of ASD children is also a key factor for the worsening of ASD symptoms. Children with autism have food selectivity and limited diets due to smell, taste, or other characteristics of foods. This determines eating routines and food intake patterns, with consequent deficiency or excess of some aliments. Several studies have tried to show a possible relationship between nutritional status and autism. In this review we describe, emphasizing the limits and benefits, the main current empirical studies that have examined the role of maternal diet during gestation and diet of ASD children as modifiable risk factors at the base of development or worsening of symptoms of autism.

[Apheresis Techniques]

Apheresis therapies play an important role in the treatment of many pathologies, both as first-line and rescue therapies after drug failure or drug toxicity and, furthermore, when it is important to reach a therapeutic goal in a short time. Apheresis devices have evolved at an astounding rate over the last decades. Therapeutic apheresis are usually part of a treatment plan, so, a patient-centered approach to select the most appropriate treatment for each patient, balancing personal preferences, medication interferences and technological availability can significantly influence the choice of the protocol to be used. But, if the wide diversity of apheresis treatments may offer a tailored-patient approach, it can also create concerns on the right decision about the most appropriate protocol. Therapeutic apheresis - whose purpose is to cure diseases due to abnormality of blood cells or to toxicity of plasma substances - and, productive apheresis - whose purpose is to produce autologous or allogeneic therapeutic hemocomponents - are widely known as plasma-treatments and cytapheresis. The elementary techniques in apheresis are well represented by three physical separation methods of blood components: 1. differential centrifugation; 2. membrane filtration; 3. adsorption of proteins or cells, from whole blood or from plasma already separated. Starting from these three processes, several apheretic techniques have been developed to ensure, in expert hands, excellent therapeutic efficacy together with a low profile of adverse events.

Comparative instrumental evaluation of efficacy and safety between a binary and a ternary system in chemexfoliation

OBJECTIVE

To instrumentally evaluate the efficacy and the safety of a new ternary system chemo exfoliating formulation (water-dimethyl isosorbide-acid) vs traditional binary systems (water and acid) where the acid is maintained in both the systems at the same concentration.

METHODS

Different peelings (binary system pyruvic acid and trichloroacetic acid-TCA, and ternary system pyruvic acid and TCA) were tested on the volar forearm of 20 volunteers of both sexes between 28 and 50 years old. The outcomes were evaluated at the baseline, 10 minutes, 24 hours, and 1 week after the peeling by means of noninvasive skin diagnosis techniques. In vivo reflectance confocal microscopy was used for stratum corneum evaluation, transepidermal waterloss, and Corneometry for skin barrier and hydration, Laser Doppler velocimetry in association with colorimetry for irritation and erythema analysis.

RESULTS

The instrumental data obtained showed that the efficacy and safety of the new ternary system peel compounds were significantly higher compared with the binary system formulations tested. The new formulation peels improved chemexfoliation and reduced complications such as irritation, redness, and postinflammatory pigmentation compared to the traditional aqueous solutions.

CONCLUSION

The study showed that ternary system chemexfoliation, using a controlled delivery technology, was able to provide the same clinical effects in term of stratum corneum reduction with a significantly reduced barrier alteration, water loss, and irritation/erythema compared to traditional binary system peels.

Clinical and instrumental evaluation of a cross-linked hyaluronic acid filler dermal injection: effects on nasolabial folds skin biophysical parameters and augmentation from a single-dose, monocentric, open-label trial

BACKGROUND

When a hyaluronic acid dermal device to fill soft tissues is chosen, efficacy, safety and durability are key concerns. This is an open-label prospective study to instrumentally evaluate the effects of HA filler dermal injection on nasolabial folds skin biophysical parameters and augmentation.

METHODS

A single Italian site treated female subjects aged 40-55, for nasolabial folds, with a single standardized injection. The outcome was evaluated with objective quantitative measurements after 90 (T1) and 180 days (T2) from the injection comparing to baseline (T0) by means of Corneometer (skin hydration measurement), Cutometer (skin elasticity measurement), and Visioface devices for digital and UV computerized image analysis. Secondary endpoints were safety assessment, subject investigator satisfaction with the intervention. Assessment of aesthetic results included photographic documentation.

RESULTS

The computerized image analysis confirmed the clinical assessment showing statistically significant reduction in nasolabial folds both at T1 and T2. Visioface® indexes showed a marked and statistical significant response. An excellent profile of satisfaction of the product at T2 from investigators and patients was recorded. Skin hydration and elasticity did not show significant changes.

CONCLUSIONS

In our study, a standardized HA filler dermal injection on nasolabial folds did not influence skin biophysical parameters such as skin hydration and elasticity. Nasolabial folds showed a persistent and significative response at T2 confirmed by instrumental evaluation. The tolerability and safety profile of the product was excellent.

OBJECTIVE

To investigate the effects of topical application of a Gold Silk Sericin (GSS) complex on biophysical parameters related to skin ageing.

METHODS

A range of non-invasive bioengineering methods were deployed in an 8-week randomized, double-blinded, vehicle-controlled, split-face study among 40 female subjects aged 40-70. Endpoints measured included expert grades of skin condition, stratum corneum (SC) hydration, SC barrier function, elasticity and surface topography.

RESULTS

The GSS complex produced significant single-variable (P < 0.05) improvements in SC hydration, barrier function, elasticity and surface topography compared with the Vehicle control.

CONCLUSION

The GSS complex examined in this study represents an interesting new cosmetic topical technology with which to address multiple aspects of aged/photoaged female facial skin.

Combined use of monopolar radiofrequency and transdermal drug delivery in the treatment of melasma

BACKGROUND

Melasma is a common acquired pigmentary disorder that has a considerable psychological impact on the patient. The recurrent and refractory nature of this condition makes it difficult for treatment.

OBJECTIVE

We aim to evaluate the efficacy and safety of a combined system that simultaneously uses monopolar radiofrequency (RF) and transdermal drug delivery of phytocomplex containing 1% kojic acid in the treatment of melasma.

MATERIALS AND METHODS

Fifty patients affected by melasma underwent 6 sessions of treatment at 1-week intervals. The outcome was evaluated before treatment (T0) and 1 month (T1) and 6 months (T2) after treatment using the Melasma Area and Severity Index score, a Mexameter, and Visioface devices for digital and ultraviolet computerized image analysis of skin color.

RESULTS

The image analysis showed that hyperpigmentation was significantly reduced at T1 and T2 compared with baseline. Melasma Area and Severity Index score, the average melanin score, and the average erythema values showed a significant reduction. No side effects were observed or reported.

CONCLUSION

This study describes the first report of improvement in melasma through the combined use of monopolar RF with transdermal delivery of depigmenting agents. This could be a safe, tolerable, and effective alternative tool for the treatment of melasma.

Cognitive deficits in patients with low and high grade gliomas

AIM

Studies in the literature with specific information concerning the neuropsychological alterations in patients with high and low grade gliomas are poor. The aim of the present study was to investigate and compare the cognitive functioning in patients with high and low-grade glioma pre- and postoperatively.

METHODS

Between January 2009 and January 2011 27 patients with high-grade glioma (HG group) and 15 patients with low-grade glioma (LG group) were neuropsychologically assessed in the preoperative time, as well as 6 months and 1 year after surgery. During the examination, memory, visuo-constructive abilities, language and executive functions were tested. In addition in the preoperative time, the effect on cognition of lateralization, size and edema was analyzed for each group.

RESULTS

Both in the HG and LG group statistical comparisons of the pre- and postoperative assessments of cognitive abilities showed a postoperative improvement in memory functions and in processing speed (P<0.05). In particular the analysis of the significance of clinical factors in the postoperative outcome of patients with glioma showed that lesion size, edema and lateralization affect cognitive functioning in varying degree.

CONCLUSION

These findings demonstrated different levels of impairments in executive and memory domains and in processing speed in patients with low and high grade gliomas. These deficits may have a strong impact on quality of life. Psychiatric interventions may be useful for patients and their families; in particular for helping the patient to become aware of the illness, in bolstering coping strategies, and for facilitating their support at home.
