Proteoglycan Combined with Hyaluronic Acid and Hydrolyzed Collagen Restores the Skin Barrier in Mild Atopic Dermatitis and Dry, Eczema-Prone Skin: A Pilot Study.

ABSTRACT: Dry and eczema-prone skin conditions such as atopic dermatitis and xerotic eczema primarily indicate an impaired skin barrier function, which leads to chronic pruritus. Here, we investigated the effects of a novel emollient containing H.ECM^TM liposome, which contains a soluble proteoglycan in combination with hydrolyzed collagen and hyaluronic acid. A prospective, single-arm study was conducted on 25 participants with mild atopic dermatitis or dry skin to assess the hydration and anti-inflammatory effect of the novel emollient applied daily over four weeks. All efficacy parameters, including itching severity, transepidermal water loss, and skin hydration, improved significantly after four weeks. The in vitro and ex vivo studies confirmed the restoration of the skin's barrier function. The study revealed the clinical and laboratory efficacy of H.ECM^TM liposome in reducing itching and improving the skin's barrier integrity. Thus, the use of H.ECM^TM liposome can be considered a therapeutic option for dry and eczema-prone skin.

Project description:BACKGROUND:Atopic dermatitis (AD) is associated with itch, skin inflammation and barrier disruption, and scratching, all of which may be associated with skin pain. OBJECTIVE:To characterize the patient burden of skin pain in AD. METHODS:We performed a prospective dermatology practice-based study using questionnaires and evaluation by a dermatologist. RESULTS:Overall, 305 patients (age range, 13-97 years) were included in the study, with 564 encounters. The cohort included 195 females (63.9%) and 193 whites (63.7%). The mean (SD) age at enrollment was 42.3 (18.1) years, and the mean (SD) age of patient-reported AD onset was 29.6 (31.9) years. At baseline, 144 patients (42.7%) reported skin pain in the past week, with 42 (13.8%) reporting severe or very severe pain. Twenty-four (16.8%) thought the skin pain was part of their itch, 16 (11.2%) from scratching, and 77 (72.0%) from both. Patients with skin pain were more likely to describe their itch using terms that resembled neuropathic pain. Prevalence of skin pain was increased in patients with vs without excoriations (72.6% vs 57.6%; ?2 test P?=?.02) but not other morphologic characteristics. Skin pain severity was most strongly correlated with the Patient-Oriented Eczema Measure (Spearman ??=?0.54), followed by ItchyQOL (??=?0.52), 5-dimensions of itch scale (??=?0.47), Dermatology Life Quality Index (??=?0.45), numeric rating scale for itch (??=?0.43) and sleep (??=?0.36), Patient Health Questionnaire 9 (??=?0.36), patient-reported global AD severity (??=?0.34), Eczema Area and Severity Index (??=?0.23), and objective Scoring AD index (??=?0.20) (P?<?.001 for all). Patients with both severe itch and pain vs those with only one or neither symptom being severe had significant increases in all these measures. CONCLUSION:Skin pain is a common and burdensome symptom in AD. Skin pain severity should be assessed with itch severity in AD patients and may be an important end point for monitoring treatment response.
