Background and Aim: Atopic dermatitis (AD) impacts the quality of life of patients and their families. This survey-based study aimed to understand the perspectives of physicians in Egypt and Lebanon regarding available educational initiatives and support programs for patients with AD, which was complemented by the social analytics study, offering a more comprehensive understanding of the perceptions of AD among social media users.

Methods: The survey included 200 physicians, comprising primary care physicians, family medicine physicians, pediatricians, and dermatologists from Egypt and Lebanon. The social analytics study leveraged artificial intelligence to analyze 100 million websites across the region, identifying mentions of AD-related terminologies.

Results: The physician survey uncovered gaps in AD awareness and education in Egypt and Lebanon, with limited educational initiatives and digital applications available for patients. The perceptions of physicians varied regarding the use of telemedicine in dermatological disease management. According to the social analytics study, online discussions about AD predominantly originated from Egypt, featuring educational content on causes, diagnosis, management, and AD patient journey. Discussions included news about training programs, AD-related healthcare initiatives, and drug approvals. Some authors, beauty clinics, and manufacturers actively promoted their services and products. Patients actively engaged in online discussions on self-care and natural remedies, sharing their experiences of living with AD. Notably, there were substantial volumes of incorrect and inaccurate information being shared and promoted by some authors.

Conclusion: Education about AD is crucial for patients and healthcare professionals. While social media offers opportunities for increased patient engagement, the prevalence of misinformation poses a significant challenge. Addressing issues related to education and discerning misinformation is essential for achieving optimal outcomes in the management of AD within the region.

Background: Chronic pruritus of unknown origin (CPUO) is a highly debilitating disease that lacks effective treatment. There have been case reports of effective use of Janus Kinase (JAK) inhibitors in CPUO, including a case treated with baricitinib, a selective JAK 1/2 inhibitor.

Objectives: To evaluate if itch in a cohort of CPUO patients was effectively reduced after treatment with baricitinib.

Patients and Methods: This is a retrospective case series examining all patients with CPUO who were treated with baricitinib from February 2022 to August 2023 at the National Skin Center, Singapore. Itch scores on a 0–10 numerical rating scale (NRS) at 0.5-point intervals were recorded and analyzed over time.

Results: Sixteen patients (56% women, mean age of 62.2 ± 19.7 years old) with CPUO were included in the analysis. Their mean [range] duration of chronic itch was 15.4 [1–50] years, and the mean follow-up period of baricitinib treatment was 10.2 ± 6.7 months. The median [IQR] NRS itch score before and after baricitinib treatment were 8.5 [6.5–10.0] and 3.5 [1.25–5.0], respectively, with a mean reduction in the itch score of 4.9 ± 2.7 (p < 0.0001). All except one patient reported significant improvement in itch severity. There were no reports of symptomatic side effects, except for a drop in hemoglobin in a patient with thalassemia and a dry throat in another patient. There were five cases of mild elevation in creatine kinase levels, three of which normalized over time, and two cases of mild elevation in creatinine levels.

Conclusion: This study suggests that baricitinib can effectively reduce pruritus in patients with CPUO and supports the conduct of randomized placebo-controlled trials to better elucidate the efficacy of JAK inhibitors in management of CPUO.

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects the quality of life (QoL) of afflicted patients. This current study was designed to assess the QoL of first-degree relatives of HS patients and the various associated parameters.

Methods: We conducted this cross-sectional study at the Outpatient Dermatology Clinics of Shahid Faghihi Hospital and Imam Reza Clinic, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran, from 2021 to 2022. Thirty-nine first-degree relatives of thirty-nine patients with HS were selected to enter this cross-sectional study, through the census sampling method. The Family Dermatology Life Quality Index (FDLQI) was used to determine the scores.

Results: A total of 39 patients (24 men and 15 women) with HS were included in the present study. The mean total score of the FDLQI questionnaire was 9.10 ± 6.77, which indicates a moderate impact on the QoL of the first-degree relatives of HS patients. In HS patients with underlying diseases, FDLQI scores were greater. Other first-degree relatives had a higher average overall FDLQI score than the patient’s spouse. Comorbid first-degree relatives showed considerably higher FDLQI scores than those without. FDLQI scores increased with first-kin age.

Conclusion: The FDLQI score of first-degree relatives of HS patients is considerably affected by any other underlying condition. Additionally, FDLQI scores were substantially associated with the first-degree relative’s relationship with the patient (spouse vs. other relation) and the patient’s and relative’s underlying diseases.

Objective: To investigate the distribution characteristics of specific immunoglobulin E (IgE) to dust mite components in patients with atopic dermatitis (AD), aiming to provide a reference basis for the development of microarray protein chips for allergen component discrimination diagnosis and personalized desensitization therapy.

Methods: A total of 55 patients who visited Huishan District People’s Hospital of Wuxi City, Xishan People’s Hospital of Wuxi City, and People’s Hospital of Wuxi City from January 2023 to December 2023 were selected. The results of serum total IgE (total IgE) and specific IgE detection were analyzed.

Results: Among the 55 patients, 54 (98.2%) were positive (cutoff value > 0.35 Ua/mL, the normal value for serum total IgE is under 150–400 IU/mL) for serum total IgE antibodies, 52 (94.6%) were positive for Dermatophagoides pteronyssinus (Dp)–specific IgE antibodies, and 50 (90.9%) were positive for Dermatophagoides farinae (Df)–specific IgE antibodies. The protein chip results were consistent with the existing Phadia detection results.

Conclusion: The development of chips based on CRD (component-resolved diagnosis) cannot only rely on IgE binding rate to assist in precise treatment of patients but also choose personalized desensitization therapy, providing more practical recommendations for preventing cross-allergy, avoiding allergic environments, or ingesting sensitizing foods for susceptible individuals.

Dermatophyte infections of the skin and nails are frequent, but current antimycotics have several drawbacks. In search of new treatments, we looked into the vast array of herbal active agents. Derived from plants, they are sustainable, agreeable for patients, and may have less side effects than traditional antimycotics. In this study, we assessed 43 herbal agents for their effectiveness against Trichophyton rubrum (T. rubrum), Trichophyton benhamiae (T. benhamiae), Trichophyton tonsurans (T. tonsurans), and Microsporum canis (M. canis), four major human dermatophyte pathogens. The antifungal effect was tested by incorporating the agents into agar plates and measuring the dermatophyte growth after 7 days. Against T. rubrum, 16 out of 43 herbal agents showed total inhibition of dermatophyte growth. 14 out of 43 herbal agents inhibited the growth of T. benhamiae completely. 18 out of 43 herbal agents were effective against T. tonsurans. Against M. canis, 15 out of 43 herbal agents showed total growth inhibition. Twelve herbal agents inhibited the growth of all tested dermatophytes completely. This study demonstrates the high antimycotic potential of herbal therapeutics and identified promising candidates for the topical treatment of dermatomycoses. Substances are highly agreeable and should be tolerated well. Some might even provide new options for the systemic treatment of fungal diseases.

Studies find climate therapy (CT) at the Dead Sea of psoriasis efficient for induction therapy, but few studies address disease relapse, long-term maintenance using CT, confounders, and the patient perspective. CT combines sunlight, balneotherapy, stress reduction, and education. This study aimed to examine Dead Sea CT and relapse of psoriasis over a 2 years period, patients’ satisfaction, and treatment outcome and preference relative to other therapies. A structured questionnaire was offered to patients, who during the recent 2 years had undergone a 4 week course of CT at the Dead Sea. Patients included applied for a new CT session due to relapse of their psoriasis. Questionnaire items covered their recall of relapse, disease severity, potential triggers of relapse and patient’s preference relative to other treatment options. The study enrolled 40 patients, with an average age of 55.5 years. CT was highly effective and resulted in marked reduction in the affected skin area, from 16% to less than 1% of the body surface. The median time from CT to first visible new lesion was 4.8 months, to first bothersome relapse 6.1 months and to full blown relapse 8.0 months. Patient satisfaction with conventional therapeutic modalities, especially oral methotrexate, was reserved, and CT was generally preferred. Relapse after CT was an inclusion criterion, and patients with long-lasting healing were not assessed. CT for 4 week treatment course of moderate to severe psoriasis at the Dead Sea which was studied in patients with relapsing disease was highly efficient for induction for clearing of the skin, matching new biologicals. In the studied group, return to prestate level took median 8 months on average. Patients’ satisfaction with CT scored high, and maintenance through repeated Dead Sea treatments often is best treatment of this segment having intolerance or poor effect of other treatments, or fear of medicines as a personal attitude.

Background. Keloids are benign fibroproliferative tumors that are unique to humans. However, the exact mechanism of keloid formation remains unclear. The inflammatory cytokines released by immune cells can activate fibroblasts, connective tissue cell proliferation, and angiogenesis. Hypoxia is common in the process of fibrosis in many diseases. This study aimed to investigate the relationship between immune response, hypoxia, and keloid formation. Methods. Gene methylation and expression data were downloaded from the GEO database. Thereafter, differentially methylated genes associated with immunity and hypoxia were identified. Machine learning was performed to identify potential diagnostic/immunity/hypoxia-related differentially methylated/expressed genes, followed by analysis of functional enrichment, transcription factors, protein-protein interactions, and expression validation by reverse transcription quantitative polymerase chain reaction and immunohistochemistry. Results. In total, 16 immunity/hypoxia-related hypermethylated low-expression genes and 18 immunity/hypoxia-related hypomethylated high-expression genes were identified in keloids. Based on machine learning, nine differentially methylated and expressed genes were selected as potential diagnostic markers for keloids, including two hypoxia-related genes (CDKN1A and PGAM2) and seven immunity-related genes (DCD, PTGDS, WFIKKN1, SEMA5A, IL1R1, ITGAL, and SOS1). Some significantly enriched signaling pathways were identified, including the FoxO, PI3K-Akt, focal adhesion, and ErbB signaling pathways. SOS1 is involved in disease regulation with 65 transcription factors and has a higher interaction score with other molecules. Conclusions. Two hypoxia-related genes (CDKN1A and PGAM2) and seven immunity-related genes (DCD, PTGDS, WFIKKN1, SEMA5A, IL1R1, ITGAL, and SOS1) could be considered potential diagnostic markers for keloids, and may be helpful in understanding the importance of oxygen balance and immune regulation in keloids.

The treatment of keloids, particularly in high-tension areas, is challenging due to their extension beyond the original wound boundaries and high recurrence rates, thereby rendering traditional treatments ineffective. In this study, we investigated the effectiveness of a novel single-stage treatment approach that combined acellular dermal matrix (ADM) with keloid-specific epidermal skin grafting. To further prevent recurrence after neo-skin formation, the treatment was followed by fractionated laser and radiation therapy (LCR). Seven patients with high-tension keloids, including one with keloids at two locations, were treated and followed-up for an average of 15.9 months. The patients showed significant improvements in wound healing and skin appearance, with a marked reduction in the Patient and Observer Scar Assessment Scale (POSAS) (scores from 91.1 ± 5.6 to 23.8 ± 6.1 (p < 0.001)). This approach effectively minimizes tension, reduces the likelihood of keloid recurrence, and serves as a viable alternative to conventional methods that often involve challenges related to donor-site acquisition. No recurrence was observed during the follow-up period, indicating a promising innovation in the management of extensive keloids and offering improved healing and esthetic outcomes, particularly in high-tension areas.

Palmoplantar pustulosis (PPP) is often considered as pustular psoriasis of extremities. Benvitimod has been approved for mild to moderate psoriasis. We thus designed this study to evaluate the efficacy and safety of benvitimod for treating PPP. Of 47 PPP patients recruited from 4 hospitals, 40 finished 8 weeks visit and completed 4 weeks safety follow-up visit. The Palmoplantar Pustular Psoriasis Area and Severity Index (PPPASI) and Dermatology Life Quality Index (DLQI) scores fell continuously. At week 8, mean ± SD PPPASI and DLQI were 3.39 ± 3.86 (p < 0.0001) and 2.49 ± 3.34 (p < 0.0001), respectively. At week 8, 70% (28/40) achieved PPPASI-50 response, 35% (14/40) achieved PPPASI-75 response, and 17.5% (7/40) achieved PPPASI-90 response. Relapse occurred in 7.5% (3/40) of the patients. Of 47 patients enrolled, self-reported compliance was 12.77% (6/47). Common drug-related adverse events (5/47) included xerosis cutis. Only one patient’s disease progressed during treatment. Our study demonstrated the efficacy and safety of benvitimod.

Background: Neurofilament light chain (NfL) has been identified as a biomarker in neuroaxonal injury. Cutaneous nerve injury resulting from inflammation and/or forced scratching may also potentially affect serum NfL (sNfL) levels.

Objectives: We aimed to explore the relationship between sNfL levels and the severity of skin inflammation and scratch lesions in patients with pruritus.

Methods: In this cross-sectional pilot study, we measured the sNfL levels of 10 patients with pruritus of different aetiologies, and calculated age- and BMI-adjusted sNfL percentiles based on a normative database consisting of 4532 control individuals. Next, we investigated the relationship between the levels of sNfL and the severity of skin inflammation and scratching injuries in these patients using a newly-created Skin Inflammation and Scratch Lesions (SISL) score.

Results: A positive correlation was observed between sNfL levels and the severity of skin inflammation and scratch lesions as measured by the SISL score (Spearman’s rho = 0.70, p = 0.031). When correlated separately, both the “skin inflammation only” and “scratch lesions only” scores correlated positively with sNfL levels (Spearman’s rho = 0.68, p = 0.031; Spearman’s rho = 0.66, p = 0.041, respectively).

Conclusions: sNfL may be a potential biomarker for cutaneous nerve injury associated with skin inflammation and/or scratching.
