LED-emitted blue light improves quality of life and reduces fatigue after COVID-19 infection.

Introduction: Despite multiple clinical presentations of long COVID, the most common symptom encountered by the patients is fatigue which significantly impacts daily functioning and quality of life. There are, however, multiple unanswered questions regarding the treatment of fatigue among long COVID patients. Several studies highlighted that repetitive exposure to blue light may alleviate the fatigue in different groups of patients but the studies on the efficacy of blue light therapy in treatment of fatigue in long COVID patients are lacking.

Psoriasis and Seasonality: Exploring the Genetic and Epigenetic Interactions.

Psoriasis is a multifactorial, chronic, and inflammatory disease that severely impacts patients' quality of life. The disease is caused by genetic irregularities affected by epigenetic and environmental factors. Some of these factors may include seasonal changes, such as solar radiation, air pollution, and humidity, and changes in circadian rhythm, especially in the temporal and polar zones.

Isolated melanoma metastasis in a patient with large congenital nevus without detectable primary melanoma: a case report and review of literature.

Giant congenital pigmented nevi constitute an extremely diverse group of skin lesions with varying morphologies. These nevi are often associated with many clinical implications, such as increased risk of melanoma and the presence of neurocutaneous melanosis, with melanoma being the primary concern. We present a rare case of a 62-year-old patient with a giant congenital birthmark who reported to the oncology department due to a tumor in the lower abdomen detected during an ultrasound examination.

Factors Influencing the Clinical Course of Bullous Pemphigoid among Geriatric Patients: A Pilot Study.

: Bullous pemphigoid (BP) is the most common autoimmune blistering disease affecting mainly elderly patients. Still, little is known about the pathogenesis of pruritus in BP or the factors that affect the clinical course of the disease. This study aimed to evaluate the factors influencing the clinical course of BP among older patients.

Effectiveness and Safety of Etanercept in Paediatric Patients with Plaque-Type Psoriasis: Real-World Evidence.

: Psoriasis is a chronic, multisystemic, inflammatory disease affecting approximately 1% of children and significantly reducing their health-related quality of life. Etanercept is a biologic fusion protein-blocking TNF-α and belongs to one of the biologics used among the children population. The purpose of this study was to assess the effectiveness and safety profile of etanercept in paediatric patients with plaque-type psoriasis.

Prospective Clinical Study: Full-Body Blue Irradiation in the Treatment of Atopic Dermatitis.

Introduction: Ultraviolet-free (UV-free) blue light phototherapy has emerged as a promising option due to its reported efficacy and minimal adverse effects. This study aims to evaluate the effectiveness of full-body blue light irradiation in both adult and pediatric patients with atopic dermatitis (AD), assessing its impact on skin condition and mood regulation by investigating serum concentrations of serotonin and kynurenine pathway metabolites.

Methods: 20 patients (age 9-45) with moderate and severe AD were included in the study.

The effectiveness of omalizumab therapy in patients with chronic spontaneous urticaria: the experience of a single-centre study in Poland.

Introduction: Omalizumab, which is a recombinant, humanised anti-immunoglobulin-E antibody, is the only approved drug for antihistamine refractory chronic spontaneous urticaria (CSU). It has been reported that it is an effective and safe drug, but the data about long-term effectiveness are still lacking.

Aim: To perform a retrospective analysis of the patients with CSU treated with omalizumab at the dermatology department to assess effectiveness of omalizumab therapy in the single centre in Poland.

A randomized, double-blind, phase III study assessing clinical similarity of SB17 (proposed ustekinumab biosimilar) to reference ustekinumab in subjects with moderate-to-severe plaque psoriasis.

Background: Ustekinumab (UST) is a safe and effective treatment for moderate-to-severe psoriasis.

Objectives: To compare efficacy, safety, pharmacokinetics (PK), and immunogenicity of the proposed UST biosimilar SB17 with reference UST in subjects with moderate-to-severe plaque psoriasis.

Methods: In this randomized double-blind study, subjects were randomized to receive 45 mg of SB17 or UST subcutaneously at week 0, 4, and every 12 weeks.

Does the effectiveness of biological medications in the treatment for psoriasis depend on the moment of starting therapy? A preliminary study.

Introduction: It is well known that biological medications acting on selected elements of the immune response are highly effective in psoriasis treatment. It is a common perception that psoriasis is a seasonal disorder with improvement in warmer months, however it has not been unequivocally confirmed. It is not known whether the time of year of starting systematic therapy for psoriasis influences treatment outcomes.

Vaccinations in Selected Immune-Related Diseases Treated with Biological Drugs and JAK Inhibitors-Literature Review and Statement of Experts from Polish Dermatological Society.

The growing use of biological drugs in immune-mediated chronic diseases has undoubtedly revolutionized their treatment. Yet, the topic of vaccinations in this group of patients still raises many concerns and implies many therapeutic problems that require discussion and standardization of management. The aim of this literature review is to present current knowledge regarding safety and efficacy of vaccinations in dermatological and rheumatological patients treated with biological drugs and JAK inhibitors.

Efficacy and Safety of Candidate Biosimilar CT-P43 Versus Originator Ustekinumab in Moderate to Severe Plaque Psoriasis: 28-Week Results of a Randomised, Active-Controlled, Double-Blind, Phase III Study.

Background: CT-P43 is a candidate ustekinumab biosimilar in clinical development.

Does molecular scarring in psoriasis exist? A review of the literature.

Plaque psoriasis is a chronic inflammatory dermatosis characterized by a tendency to recur in the same locations after discontinuation of treatment. The implementation of therapy with drugs targeting cytokines like interleukin (IL) 17A (IL-17A) and IL-23 has revolutionized the treatment of psoriasis and enabled the achievement of skin without lesions. However, despite the clinical resolution of psoriatic eruptions, cells that maintain the local memory of the disease remain in the dermis and epidermis, constituting a kind of molecular scar.

Shift in skin microbiota of children with atopic dermatitis after topical gentian violet application.

Introduction: Increasing usage of antimicrobial agents may contribute to bacterial resistance in atopic dermatitis (AD). In this case an alternative topical treatment might be gentian violet (GV), suggested for its antibacterial and antifungal properties.

Aim: To assess the microbial composition of lesional skin in children with AD and a control group aged 2-12 years, before and after 3 days of 2% aqueous GV application.

Off-label medications in the treatment of hospitalized children with atopic dermatitis.

Introduction: Off-label prescribing is defined as using medications outside conditions of the marketing authorisation including their licensed indications, dosage, age and route. Atopic dermatitis (AD) is the most common chronic skin condition in children which can be related to a high level of off-label prescribing.

Aim: To investigate the frequency of off-label prescribing and the medications involved in relation to indications and age in paediatric patients hospitalized for atopic dermatitis in a paediatric dermatology ward in 2019.
