Treatment of Seborrheic Dermatitis Using a Novel Herbal-based Cream.

ABSTRACT: Objective: Seborrheic dermatitis is a common relapsing inflammatory skin condition occurring in approximately 3 to 5 percent of the general population. Current available therapies control, but do not cure seborrhea. The study's objective was to determine the safety and efficacy of a barrier-based, nonsteroidal cream incorporating herbal extracts as a treatment for facial seborrheic dermatitis. Design: Interventional, open label, safety/efficacy study. Setting: At the baseline visit, the investigator selected a target area on the face. The target area was evaluated for Investigator Static Global Assessment, desquamation (scaling), induration (inflammation), and erythema (redness) as well as self-assessed pruritus. Participants: Thirty-two subjects with seborrheic dermatitis were enrolled in the study. Measurements: Subjects were instructed to use the study medication twice a day, morning and evening, for a consecutive period of 42 days. In addition to the baseline visit (Day 0), subjects visited the clinic for two follow-up visits at Days 14 and 28 and for a final visit at Day 42. At each visit, all parameters were evaluated. Results: A reduction in all parameters evaluated was seen at almost all timepoints, improving more from one timepoint to the next during the study period. In addition, the patients expressed a high degree of satisfaction with the treatment. No adverse events were reported during this study. Conclusion: The study showed that after six weeks of treatment, the face cream provided improvement in Investigator Static Global Assessment, pruritus, desquamation, induration, and erythema.

Project description:IntroductionThe pathogenesis of seborrheic dermatitis (SD) is multifactorial and traditional treatments may not target all aspects of it. The aim of this study was to evaluate short-term anti-fungal, anti-microbial, anti-inflammatory and anti-pruritus properties of a novel non-steroidal cream (NSC) containing piroctone olamine, zinc salt of L-pyrrolidone carboxylate (PCA), hydroxyphenyl propamidobenzoic acid, biosaccharide gum-2 and stearyl glycyrrhetinate in patients with face and chest SD.MethodsTwelve male subjects affected by SD, presenting face and chest manifestations, were enrolled. Patients were instructed to apply NSC twice a day, performing regular visits at baseline (W0), after 7 (W1) and 14 (W2) days of treatment. A limitation of the study was that no control group treated with the vehicle without active ingredients was enrolled. To evaluate the efficacy of the NSC, investigator's assessments were represented by scoring index (SI) and investigator's global assessment score (IGA). In order to assess NSC anti-fungal and anti-microbial effects, skin scale scrapings were collected and used for Malassezia furfur (MF) and Staphylococcus epidermidis (SE) cultures. In parallel, in order to assess NSC anti-inflammatory effects, gene expression of IL-1α, IL-1β, IL-6, IL-8, and TNF-α was assessed. In addition, anti-pruritus effects were also evaluated through gene expression of cathepsin S and L-histidine decarboxylase.ResultsSI mean scores significantly decreased at W1 and, to a greater extent, at W2 compared with W0. The IGA score registered an important improvement efficacy both for face and chest, from W1 to W2. MF and SE growth was already inhibited at W1, with a more pronounced decrease at W2. Gene expression of all analyzed mediators was significantly reduced at W1 compared to W0.ConclusionIn conclusion, our assessment is that NSC is an effective and well tolerated treatment option for SD with anti-fungal, anti-microbial and anti-inflammatory properties.Trial registrationISRCTN registry, ISRCTN77871064 (retrospectively registered October 17, 2019).

Project description:IntroductionFew studies have investigated the long-term effects of a maintenance regimen in the prevention of relapses in scalp seborrheic dermatitis (SD), in particular following biomarker changes.Materials and methodsA new shampoo containing beta-glycyrrhetinic acid (18βGA) in addition to cyclopiroxolamine (CPO) and zinc pyrithione (ZP) was tested in 67 subjects suffering from SD with moderate to severe erythema and itching in a biphasic study. After a first common intensive treatment phase (investigational product thrice a week × 2 weeks), subjects randomly received the investigational product once a week × 8 weeks (maintenance) or a neutral shampoo (discontinuation) in a comparative, parallel group maintenance phase. Efficacy was assessed clinically (overall clinical dandruff score, erythema, overall efficacy, self-evaluation), biochemically and microbiologically by quantitative polymerase chain reaction (qPCR), high performance liquid chromatography (HPLC) or enzyme-linked immunoabsorbent assay (ELISA) analysis of scale samples (Malassezia species (restricta and globosa), cohesion proteins (plakoglobins), inflammation (Interleukin (IL)-8, IL-1RA/IL-1α) and pruritus (histamine, cathepsin S) markers).ResultsDuring the intensive treatment phase, SD improved significantly (p < 0.0001) with a decrease in clinical signs as well as Malassezia species, cohesion proteins, inflammation and pruritus markers. During the maintenance phase, the improvement persisted in the 'maintenance' group only, with a significant intergroup difference. A consistently positive relationship was found between dandruff, itching, erythema and Malassezia populations, histamine levels and IL-1RA/IL-1α ratio.ConclusionThe effectiveness of this maintenance regimen was objectively demonstrated at the clinical, biochemical and microbiological level. Correlations between clinical signs and biomarkers could provide clues to explain the resolution of SD and confirm the interest of biomarkers for SD treatment assessment.
