Evaluation of the efficacy, safety, and side effects of secukinumab in patients with moderate-to-severe psoriasis: real-world data from a retrospective multicenter study.

Background: Clinical studies have demonstrated that IL-17A inhibition with secukinumab is effective for clearing the skin of patients with psoriasis and has a favorable safety profile.

Objective: The authors aim to determine whether secukinumab is effective and safe for the treatment of moderate-to-severe chronic psoriasis based on clinical experience with this drug.

Method: The authors conducted a multicenter retrospective study in nine referral centers and included patients with psoriasis who had received secukinumab between March 2018 to November 2020.

The impact of COVID-19 pandemic on psoriasis patients, and their immunosuppressive treatment: a cross-sectional multicenter study from Turkey.

Background: Immunosuppressive therapy has been a great concern during the pandemic. This study aimed to evaluate the pandemic's impact on psoriasis patients treated with immunosuppressive drugs.

Material And Methods: The multicenter study was conducted in 14 tertiary dermatology centers.

[Relationship of Alexithymia, Rumination and Coping Style with Psoriasis and Their Effects on The Clinical Features].

Objective: A relationship has been demonstrated between stress and the increase in the skin plaques in psoriasis. In addition, psoriasis is observed in cases of severe alexithymia and stress. In depression and various psychiatric disorders, there is a relationship between rumination and both the onset and persistence of the disease.

Levels of TNF-α, IL-6, IL-17, IL-37 cytokines in patients with active vitiligo.

Objectives: Vitiligo is an autoimmune disease, and its pathogenesis involves changes in cytokine levels in the affected patients. Tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, and IL-17 from pro-inflammatory cytokines, IL-37 in a recently detected anti-inflammatory activity. The aim of our study was to determine serum TNF-α, IL-6, IL-17, IL-37 levels in patients with vitiligo to understand their possible roles in the disease etiology and to compare the results with the healthy controls.

Novel mutation identified in the DDB2 gene in patients with xeroderma pigmentosum group-E.

Background: Xeroderma pigmentosum (XP) is a rare photosensitive syndrome, which is divided into eight complementation groups (XP-A to XP-G and XPV) and characterized by skin cancers diagnosed at early age. A family of seven members (age range between 5 and 47 years) with carriers of the novel nonsense mutation that causes XP-E type were included in the current study.

Methods: DNA was isolated from peripheral blood samples of the proband, and cancer predisposition genes were sequenced with next-generation sequencing.

Long-term follow-up effect of omalizumab in chronic spontaneous urticaria and its association with serum C-reactive protein levels.

This study aims to determine the efficacy of omalizumab, a humanized monoclonal anti-immunoglobulin E antibody, in patients with chronic spontaneous urticaria (CSU) refractory to conventional therapy, together with the evaluation of serum CRP levels. All the patients with a diagnosis of CSU who were continuously treated with omalizumab (300 mg/mo) for at least 3 months between June 2016 and July 2019 were included in this study. Urticaria activity score (UAS-7) was used for assessment of disease activity.

The role of serum vitamin D levels in vitiligo.

Introduction: Vitiligo is a common acquired pigmentary skin disorder. Vitamin D is responsible for skin pigmentation, increases tyrosinase activity and melanogenesis, and exhibits immunoregulatory functions. Low levels of vitamin D are associated with many autoimmune diseases, including systemic lupus, diabetes mellitus, rheumatoid arthritis, multiple sclerosis and alopecia areata.
