This study aims to investigate the anti-demodex potential of spilanthol, a product obtained from the Spilanthes Acmella plant, by determining the minimal effective dose for the first time in the literature. Demodex mites were obtained from 70 patients with standard superficial skin biopsy. Spilanthol extract was used at 1%, 2%, 3%, 4%, and 5%. Standard immersion oil was used for the negative control, and permethrin 5% was used for the positive control group. The dependent variable is the survival time of the mite. Comparisons with the negative control group, the anti-demodex effect demonstrated itself in all groups, creating a statistically significant difference (p < 0.001). The positive control group, had 3%, 4%, and 5% spilanthol rates which were very similar to the results with 5% permethrin (p > 0.05). Higher concentrations than 3% did not make any additional contribution to survival times. This is the first attempt to show the dose-dependent acaricidal effect of spilanthol on demodex mites. Even the 3% dose shows similar results to 5% permethrin, and no additional effect increase was observed at higher doses. Therefore, in vivo, studies may be planned with a 3% spilanthol dose for further studies.</p>","PeriodicalId":8203,"journal":{"name":"Archives of Dermatological Research","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142035078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Icariin, a natural compound extracted from the herb Epimedium, has been traditionally used for its potential anti-inflammatory and antioxidant properties. This study aimed to investigate the regulatory effects of icariin on AD-like symptoms and to elucidate its underlying mechanisms. The effects of icariin on TNF-α/IFN-γ-induced HaCaT cell injury were assessed using various assays, including cell counting kit-8 for cell viability, flow cytometry for reactive oxygen species (ROS) levels, and colorimetric assays for malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity. In addition, the study performed enzyme-linked immunosorbent assays to assess cytokines (IL-1β, IL-6, and IL-8) and chemokines (MDC, TARC, and RANTES) levels. Flow cytometry was used to quantify apoptotic rate, while a wound-healing assay was conducted to assess cell migration. The expression of WT1 associated protein (WTAP) and serpin family B member 4 (SERPINB4) at the mRNA and protein levels was determined using qRT-PCR and western blotting, respectively. The associations between WTAP and SERPINB4 were analyzed using RNA immunoprecipitation assay and m6A RNA immunoprecipitation assay. Icariin treatment significantly mitigated TNF-α/IFN-γ-induced oxidative stress, inflammatory response, and apoptosis in HaCaT cells, while also reversing the inhibitory effect on cell migration. Icariin reduced the expression of WTAP in TNF-α/IFN-γ-stimulated HaCaT cells. Overexpression of WTAP reversed the effects of icariin in TNF-α/IFN-γ-stimulated HaCaT cells. WTAP silencing inhibited the mRNA stability of SERPINB4 through the m6A modification. SERPINB4 overexpression attenuated the effects of WTAP silencing on oxidative stress, inflammatory response, apoptosis, and migration of TNF-α/IFN-γ-stimulated HaCaT cells. Icariin treatment downregulated SERPINB4 expression by regulating WTAP in TNF-α/IFN-γ-stimulated HaCaT cells.

SCORTEN is an established prognosticator index employed in SJS/TEN patients to evaluate their severity degree and mortality risk. Many studies done in the recent past have indicated that neutrophil-lymphocyte ratio (NLR) is related to disease activity in several dermatological diseases. Hence, this study has been performed to correlate the NLR of each patient with their respective SCORTEN values and assess whether NLR can be used as a prognostic marker in SJS/TEN. A single centre, retrospective, 4 year study was conducted at a tertiary care hospital. The required clinical and laboratory data were obtained from existing IP records of all cases of SJS/TEN disorders admitted in the last 4 years in our hospital between May 1st 2019 and April 30th 2023. The correlation coefficient and p value were analysed using the Spearman's rank correlation. The total sample size of the study was 22 patients. A female preponderance (59.1%) with an age range between 10 to 74 years was noted. Drugs were the main triggering factor in all the patients and antiepileptics were the most commonly implicated drug group. On statistical analysis a weak positive correlation (r = 0.182) between NLR and SCORTEN was noted, however p value was insignificant (p = 0.417). Further, mean ± SD of NLR was found to be higher in group II (patients with SCORTEN ≥ 3) as compared to group I (patients with SCORTEN < 3). On correlating NLR with each group separately, p value still remained insignificant. Elevation in NLR value reflects the systemic inflammation, but its role in predicting the severity of the disease needs further research involving larger sample size.</p>","PeriodicalId":8203,"journal":{"name":"Archives of Dermatological Research","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142035080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
