Functional brain alterations in symptomatic dermographism patients-An exploratory magnetoencephalography study.
Exp Dermatol
February 2024
Amsterdam UMC Location Vrije Universiteit Medical Center (VUmc) Amsterdam, Neurology, Amsterdam, The Netherlands.
Article Synopsis
- Symptomatic dermographism (SD) is a type of skin condition that causes hives and itching when the skin is stroked, and this study used magnetoencephalography (MEG) to explore the brain's role in this condition.
- Twelve SD patients and fourteen control participants were tested for itch response and brain activity after exposure to histamine and skin stroking, revealing that SD patients reported greater itch levels than controls.
- The study found no major brain activity differences between groups but observed notable changes in brain wave patterns, suggesting that SD may involve abnormal itch processing linked to the central nervous system.

A Case-Control Study Comparing the General Characteristics of Patients with Symptomatic Dermographism and Chronic Spontaneous Urticaria: Is Atopy a Risk Factor for Symptomatic Dermographism?
Int Arch Allergy Immunol
March 2024
Department of Allergy and Clinical Immunology, Başakşehir Çam and Sakura City Hospital, Istanbul, Turkey.
Article Synopsis
- Symptomatic dermographism (SDerm) is a common type of chronic urticaria, but there's limited information on its features and related conditions; this study aimed to compare it with chronic spontaneous urticaria (CSU).
- The research analyzed data from 361 patients (220 with CSU, 141 with SDerm) and found higher rates of asthma, allergic rhinitis, and thyroid disease in the SDerm group, along with lower disease duration and antihistamine use.
- The study concluded that patients with SDerm show a higher prevalence of atopic diseases and sensitivities to specific allergens compared to those with CSU, suggesting the need for broader studies to confirm these findings.

Symptomatic dermographism induced by oral minocycline: A report of four cases.
J Dermatol
August 2023
Department of Dermatology, Southwest Hospital, Army Medical University, Chongqing, China.
Article Synopsis
- Symptomatic dermographism (SD) is a common type of skin condition that can be triggered by external factors, but its causes are not often documented.
- Four young women developed SD after taking minocycline for acne or rosacea, with symptoms appearing 2-3 weeks after starting the medication.
- The SD symptoms resolved completely one month after discontinuing minocycline, indicating a potential link between the drug and the condition, prompting the need for further research to confirm this association and understand the mechanisms involved.
