Article Synopsis
  • Eczema herpeticum (EH) is a skin infection from the herpes virus that affects patients with atopic dermatitis (AD), and a study sought to evaluate its prevalence and characteristics in a larger group of patients.* -
  • In a study of 893 AD patients, 21.8% experienced at least one episode of EH, with over half of those (54.9%) suffering from multiple episodes.* -
  • The findings indicate a high recurrence of EH among AD patients, yet no distinct clinical traits were found to differentiate these patients, apart from an increased number of allergies.*

Background: TREATgermany, a registry for patients with moderate to severe atopic dermatitis (AD), established an additional questionnaire in spring 2020 to investigate the effects of the coronavirus pandemic on the daily life of patients with AD.

Material And Methods: A questionnaire was used to analyze general information regarding a patient's experience of the coronavirus pandemic and, using the Inventory of Life-Changing Events, the resulting personal burden. To analyze possible associations between disease severity (EASI score, oSCORAD, IGA, PGA, POEM), quality of life (DLQI) and personal burden, t-tests, analyses of variance and correlations were evaluated, controlled for sex and age.

Background: The TREATgermany registry collects data from children, adolescents, and adults with moderate-to-severe atopic dermatitis (AD) in Germany. For this purpose, clinical and patient-reported outcomes, the course of the disease, and applied therapies are observed.

Methods: TREATgermany recruits patients with moderate-to-severe AD according to the diagnostic criteria of the UK Working Party, an "Objective Scoring for Atopic Dermatitis" (oSCORAD) > 20 and/or currently antiinflammatory systemic treatment for AD or previous anti-inflammatory systemic treatment for AD within past 24 months before inclusion.

Background: As an evidence resource for the currently planned European Academy of Allergy and Clinical Immunology (EAACI) clinical practice guideline "systemic treatment of atopic dermatitis (AD)," we critically appraised evidence on systemic treatments for moderate-to-severe AD.

Methods: We systematically identified randomized controlled trials (RCTs) investigating the safety and efficacy of systemic treatments for AD up to February 2020. Primary efficacy outcomes were clinical signs, AD symptoms and health-related quality of life.

Objectives: Iron deficiency (ID) and iron deficiency anemia (IDA) are common findings in patients undergoing lipoprotein apheresis (LA). Different intravenous (iv) formulations are used to treat ID in LA patients, however guidelines and data on ID/IDA management in LA patients are lacking. We therefore performed a prospective observational multi-center cohort study of ID/IDA in LA patients, comparing two approved i.
