54112 Improvements in Psoriasis Area and Severity Index and in Percent Body Surface Area of Psoriasis With JNJ-77242113: Treat-to-Target Analyses in the FRONTIER 1 Study

Retrospective Study of the Epidemiological-Clinical Characteristics of Burns Treated in a Hospital Emergency Service (2018-2022).

Burns are a common and severe medical emergency requiring immediate specialized care to minimize damage and prevent complications. Burn severity depends on depth, extent, and location, with more complex care needed for burns on critical areas or extensive burns. Nursing is essential in burn management, providing immediate care, adapting treatments, managing pain, preventing infections, and offering emotional support for recovery. The study aims to analyse the epidemiological and clinical characteristics of burns treated at the Hospital Emergency Department of the Hospital Complex of Cáceres (Spain) from January 2018 to December 2022. It looks at factors like gender, age, hospital stay duration, emergency type (paediatric or adult), main diagnosis, skin thickness, burn degree, affected body areas, percentage of body surface area burned, and treatment types. It also investigates how treatment varies by gender, age, skin thickness, and burn severity. The relevance of this research lies in the fact that periodic epidemiological studies are essential to monitor changes in diseases, evaluate the effectiveness of interventions, detect outbreaks quickly, update knowledge on risk factors, and guide health policy decisions. This ensures an adapted and effective response to the needs of the population. Retrospective, observational study that analysed burn cases treated at the Hospital Complex of Cáceres (Spain) 2018-2022. Inclusion criteria were based on ICD-10 codes for burns, excluding severe cases not treated in this service. Data were analysed using descriptive statistics, Student's t-tests, Chi-square tests, and ANOVA. 220 patients surveyed, with a mean age of 47 years and 60.9% male. Most burns (95.5%) affected the external body surface, with a mean hospital stay of 7.86 days. Medical treatment was provided to 75.5% of patients, and 24.5% required surgical intervention. Significant differences in treatment procedures were observed according to age, skin thickness, and burn degree. Older patients had more procedures and longer hospital stays. Excision and transfer procedures were more common in full-thickness and severe burns. The findings align with previous research on burn demographics and treatment approaches. Treatment differences by age and burn severity highlight the need for tailored interventions. The study underscores the importance of comprehensive burn management, including psychological support for improved long-term outcomes. Further research could explore the impact of socio-economic factors on burn incidence and treatment. This study was not registered.

Clinical Validation of Digitally Acquired Clinical Data and Machine Learning Models for Remote Measurement of Psoriasis and Psoriatic Arthritis: A Proof-of-Concept Study.

Psoriatic disease remains underdiagnosed and undertreated. We developed and validated a suite of novel, sensor-based smartphone assessments (Psorcast app) that can be self-administered to measure cutaneous and musculoskeletal signs and symptoms of psoriatic disease. Participants with psoriasis (PsO) or psoriatic arthritis (PsA) and healthy controls were recruited between June 5, 2019, and November 10, 2021, at 2 academic medical centers. Concordance and accuracy of digital measures and image-based machine learning models were compared to their analogous clinical measures from trained rheumatologists and dermatologists. Of 104 study participants, 51 (49%) were female and 53 (51%) were male, with a mean age of 42.3 years (SD 12.6). Seventy-nine (76%) participants had PsA, 16 (15.4%) had PsO, and 9 (8.7%) were healthy controls. Digital patient assessment of percent body surface area (BSA) affected with PsO demonstrated very strong concordance (Lin concordance correlation coefficient [CCC] 0.94 [95% CI 0.91-0.96]) with physician-assessed BSA. The in-clinic and remote target plaque physician global assessments showed fair-to-moderate concordance (CCCerythema 0.72 [0.59-0.85]; CCCinduration 0.72 [0.62-0.82]; CCCscaling 0.60 [0.48-0.72]). Machine learning models of hand photos taken by patients accurately identified clinically diagnosed nail PsO with an accuracy of 0.76. The Digital Jar Open assessment categorized physician-assessed upper extremity involvement, considering joint tenderness or enthesitis (AUROC 0.68 [0.47-0.85]). The Psorcast digital assessments achieved significant clinical validity, although they require further validation in larger cohorts before use in evidence-based medicine or clinical trial settings. The smartphone software and analysis pipelines from the Psorcast suite are open source and freely available.

Ixekizumab Demonstrates Rapid and Consistent Efficacy for Patients with Psoriatic Arthritis, Regardless of Psoriasis Severity.

Skin involvement in patients with psoriatic arthritis (PsA) worsens the severity and burden of disease. Ixekizumab (IXE), a selective interleukin (IL)-17A antagonist, was compared to placebo (PBO) in the SPIRIT-P1 (NCT01695239) and SPIRIT-P2 (NCT02349295) studies in patients with PsA and evidence of plaque psoriasis. This post hoc analysis reports musculoskeletal, skin, and nail outcomes through week24 in patients from SPIRIT-P1 and SPIRIT-P2, stratified by mild, moderate, or psoriasis at baseline. This post hoc analysis pooled patients from SPIRIT-P1 and SPIRIT-P2 who were randomly assigned to PBO or IXE 80mg every 4weeks (Q4W) or every 2weeks (Q2W). Efficacy outcomes were analyzed through week24 by baseline psoriasis severity, defined by percent body surface area (BSA) affected; mild = BSA < 3%, moderate = 3% ≤ BSA ≤ 10%, severe = BSA > 10%. The primary outcomes assessed were the proportion of patients achieving American College of Rheumatology (ACR)20, ACR50, and ACR70 responses. Secondary outcomes included musculoskeletal, disease activity, skin and nail, and health-related quality-of-life measures. Similar proportions of patients achieved ACR20/ACR50/ACR70 over time across all severity subgroups and treatment arms. More than one-third of IXE-treated patients achieved ACR20 at week4, or ACR50 at week24, with no significant differences according to psoriasis severity at baseline. Disease activity outcomes were similar through week24 with both IXEQ4W and IXEQ2W, regardless of psoriasis severity at baseline. There were no significant differences over 24weeks in the proportions of IXE-treated patients with mild, moderate, or severe baseline psoriasis who achieved Minimal Disease Activity (MDA). Across all severity subgroups, IXE demonstrated Psoriasis Area Severity Index100 response as early as week4, and approximately one-third of IXE-treated patients achieved total skin clearance at week24. IXE demonstrated rapid and consistent efficacy in joint, skin, and nail for patients with PsA, regardless of baseline psoriasis severity. SPIRIT-P1 (NCT01695239), SPIRIT-P2 (NCT02349295).

Optimizing maintenance therapy in responders to abrocitinib induction: A post hoc analysis of JADE REGIMEN.

Treatment optimization may require dosing flexibility. The Phase 3 JADE REGIMEN trial (NCT03627767) evaluated maintenance of abrocitinib 200 mg-induced response in patients with moderate-to-severe atopic dermatitis (AD) randomly assigned to subsequent maintenance with continuous-dose abrocitinib (200 mg), reduced-dose abrocitinib (100 mg) or placebo. Maintenance with continuous-dose abrocitinib was associated with a stronger prevention of disease flares, but also with a higher occurrence of adverse events, compared with the reduced dose. This post hoc analysis of JADE REGIMEN aimed to identify predictors of not flaring during the maintenance period and to generate tools that can be used to assess probability of not flaring. Data were analysed from patients who responded to abrocitinib 200 mg induction therapy (12 weeks) and were randomly assigned to receive abrocitinib (200 mg or 100 mg) or placebo in the 40-week maintenance period. Demographic and baseline disease characteristics and level of response to induction were evaluated for association with not flaring using logistic regression. Parameters with a significant (p < 0.15) interaction with the treatment arm were fitted into a multivariable regression model, which was used to assess probability of not flaring. Lower percentage body surface area affected at baseline (p = 0.09), absence of prior exposure to systemic agents (p = 0.02) and greater percentage change in EASI from baseline to randomization (p < 0.001) were identified as predictors of not flaring with abrocitinib. In both abrocitinib arms, percentage change in EASI from baseline to end of induction (Week 12) was the major contributor to the probability of not flaring in the maintenance period. Maintenance of response using reduced-dose abrocitinib 100 mg may be feasible for patients with lower baseline disease severity and strong response to abrocitinib 200 mg induction treatment.

Psoriasis Area and Severity Index and its Correlation with Liver Function Test

Objective: To determine Psoriasis Area and Severity Index score and its association with LFT values in patients of psoriasis. Methodology: This cross-sectional study, was done on patients visiting the skin OPD of LUMHS Jamshoro/Hyderabad. Diagnosed patients of Psoriasis, aged between 18 and 50 years and both genders were included. A 5cc blood sample was collected from each individual to evaluate the LFT. Psoriasis Area and Severity Index (PASI) scores was defined based on the percentage of body surface area affected by psoriasis lesion. All the information was entered and analyzed using SPSS version 26. Results: The mean age of the patients was 44.81±11.10 years. Out of the total 102 patients, 74.5% were male patients and 25.5% were female. The mean duration of psoriasis was 6.46 ± 4.49 years. Out of all 32.4% had mild psoriasis (PASI &lt; 7), 40.2% had moderate psoriasis (PASI 8-12), and 27.5% had severe psoriasis (PASI &gt; 12). Regarding LFT values, 73.5% had elevated alanine transaminase (ALT), 32.4% had elevated aspartate transaminase (AST), 70.6% had elevated alkaline phosphatase (ALP), 68.6% had elevated bilirubin, and 67.6% had elevated gamma-glutamyl transferase (GGT). AST and GGT levels rise significantly linked to PASI (p- &lt;0.05). Conversely, for ALP and Bilirubin levels, there is no significant difference across severity of PASI (p- &gt;0.05). Conclusion: Patients with severe psoriasis exhibit a predisposition to hepatic dysfunction. Study observed abnormalities in liver function tests (LFT) among psoriatic patients, suggesting a potential link to liver disease development.

Real world insights for psoriasis: the association of severity of skin lesions with work productivity, medical consumption costs and quality of life

Background Psoriasis is a prevalent, chronic skin disease with a potential impact on work productivity, medical consumption costs, and quality of life. The influence of the extent of skin lesions on these outcomes is not well known. Objective We determined associations of self-reported skin lesions with self-reported work productivity, medical consumption costs, and health-related quality of life in respondents with psoriasis. Methods In this cross-sectional study, we included respondents with self-reported psoriasis in the Netherlands in an online questionnaire. We assessed the self-reported percentage body surface area (BSA) of psoriasis lesions. We used validated instruments to assess work productivity (WPAI-PsO), medical consumption costs (iMCQ), and health-related quality of life (EQ-5D-5L and the DLQI). We used ordinal logistic regression to associate BSA categories >1% versus 0-1% with outcomes adjusted for multiple confounders. Results We included 501 respondents with a mean age of 43 ± 12 years; 64% were men. Median BSA was 2% (interquartile range 1–5%). A higher BSA was associated with higher overall work impairment due to psoriasis (common odds ratio [cOR] 2.44, 95% confidence interval [CI] 1.40–4.29; n = 205), higher medical consumption costs (cOR 2.06, 95% CI 1.45–2.94) and lower health-related quality of life. Associations were strongest with a BSA cutoff of 0% or 1% compared to 2% or higher categories. Discussion In our study, having few to no lesions in psoriasis was associated with lower overall work impairment due to psoriasis, lower medical consumption costs, and higher health-related quality of life.

Analysis of cases of suicide by self-immolation in the post-mortem material of the Department of Forensic Medicine in Cracow.

Analysis of self-immolation cases and distribution of the resulting burns and their degree. The study included 16 cases from the Department of Forensic Medicine, Jagiellonian University Medical College in Cracow from 2000-2022 in which the cause of death was self-immolation. Based on the analysis of photographs and autopsy reports, drawings were made showing the exact distribution and nature of the injuries, moreover, the approximate percentage of body surface area affected was determined as well as the frequency of involvement of specific areas of the body, and the presence of previous diseases and mental disorders including previous suicide attempts. 81% of victims were male. Two age groups were predominant among the cases analyzed, namely, individuals around the age of 20, and those between 50 and 60 years of age. 44% of the deceased had burns exceeding 80% of total body surface. The most frequently involved body areas were the extremities and chest as well as head and neck. Fourth-degree burns were most prevalent on the head and neck, third-degree burns prevailed on the upper and lower extremities, second-degree burns were mostly found on the chest, and first-degree burns - on the lower extremities. There were no cases of fourth-degree burns of the buttocks. 38% of the subjects had a history of substance abuse, 56% suffered from mental illnesses, whereas 31% attempted suicide in the past. The distribution of burns in self-immolation cases is inhomogeneous. The most frequently affected area was the head, neck, chest and extremities, most likely due to victims dousing themselves with a flammable substance from the top of the head through the chest. In all cases, the immediate cause of death was burn disease, regardless of the size of the body surface area affected by the burns. The majority of victims had a history of mental illness, substance abuse or suicide attempts.

Pathogenesis and A Practical Guide to the Management of Steven-Johnson Syndrome &amp; Toxic Epidermal Necrolysis

Steven Johnson Syndrome (SJS) and Toxic Epidermal necrolysis are rare dermatological emergencies that are associated with a high degree of morbidity and mortality [1]. They are considered to be severe blistering conditions that portray an image of diffuse epidermal necrolysis in association with sloughing of the skin. SJS and TEN are effectively the same disease with the main difference being the percentage of body surface area involved. It is widely accepted that SJS belongs to the below 10% body surface area category and TEN to the more than 30% category. A Steven Johnson syndrome and Toxic Epidermal Necrolysis overlap exists when the body surface area affected is between 10 percent and 30 percent [2]. The causes of both conditions within this spectrum are most likely drug related, however certain infections can also trigger SJS/TEN but this is less likely. In a substantial number of cases the cause is idiopathic [3]. The main grading system is the SCORTEN criteria, which can also provide more information regarding prognosis and mortality [4]. Management of this condition is highly controversial with no clear guidelines but there is a wide agreement that patients should be managed in a burns unit with intravenous fluids and protection from secondary infections. Stopping all medications and investigating for the cause is important unless there is clear benefit from any single medication.

Efficacy and safety of crisaborole ointment, 2%, in participants aged ≥45 years with stasis dermatitis: Results from a fully decentralized, randomized, proof-of-concept phase 2a study

Crisaborole ointment, 2%, is a nonsteroidal topical phosphodiesterase 4 inhibitor approved for the treatment of mild-to-moderate atopic dermatitis. To evaluate the efficacy and safety of crisaborole in stasis dermatitis (SD). In this randomized, double-blind, vehicle-controlled, decentralized phase 2a study (NCT04091087), 65 participants aged ≥45years with SD without active ulceration received crisaborole or vehicle (1:1) twice-daily for 6weeks. The primary end point was percentage change from baseline in total sign score at week 6 based on in-person assessment. Crisaborole-treated participants had significantly reduced total sign score from baseline versus vehicle based on in-person (nondermatologist) assessment (-32.4% vs -18.1%, P=.0299) and central reader (dermatologists) assessment of photographs (-52.5% vs -10.3%, P=.0004). Efficacy according to success and improvement per Investigator's Global Assessment score and lesional percentage body surface area reached statistical significance based on central reader but not in-person assessments. Skin and subcutaneous tissue disorders were common all-causality treatment-emergent adverse events with crisaborole. Small sample size and short treatment duration were key limitations. In-person assessment was not conducted by dermatologists. Crisaborole improved signs and symptoms of SD and was well tolerated. Central reader assessment represents a promising approach for siteless clinical research.

Pigmentary Changes in Systemic Sclerosis are Associated with More Severe Cutaneous Sclerosis and Severity of Other Systems: A Cross-sectional Study from India.

Pigmentary changes of the skin in systemic sclerosis in the form of diffuse hyperpigmentation and salt-and-pepper pigmentation are well documented in the literature; however, its association with disease severity and extent of underlying internal organ involvement has not been well studied. To assess the correlation between morphology and extent of pigmentary changes with the degree of cutaneous sclerosis and frequency and degree of major organ involvement. This was a cross-sectional descriptive study conducted in a tertiary care teaching hospital from December 2014 to November 2016. Consecutive patients of systemic sclerosis attending the outpatient department were screened, and patients satisfying the diagnosis as per the American Rheumatism Association criteria were recruited. Skin sclerosis was quantified using modified Rodnan skin score (MRSS), whereas pigmentary changes were calculated in terms of percentage of body surface area involved by rule-of-nine method. Investigations were carried out depending on organ involvement and as per respective specialty consultations with focus on pulmonary, cardiac, and gastrointestinal systems. Of the 50 patients recruited, all had cutaneous involvement in the form of binding down of skin, followed by pigmentary changes. MRSS was significantly higher in patients with any pigmentary alteration (P = 0.03) compared to those without any pigmentary changes. There was a rising trend in between the MRSS severity and the proportion of patients with hyperpigmentation, and it was statistically significant (P = 0.04). Among systemic involvement, lung was involved in the form of interstitial lung disease in 94% patients (n = 47). However, skin pigmentation of any type was associated with lower high-resolution computed tomography scores (P = 0.02). This study shows that in systemic sclerosis patients presenting with pigmentary skin manifestations, cutaneous sclerosis is significantly higher.

Utility of Low-Dose Duvelisib for Advanced Mycosis Fungoides: A Single-Institution Study.

Duvelisib, a small-molecule phosphatidylinositol 3-kinase-δ,γ inhibitor, has shown efficacy for mycosis fungoides (MF) at dosage ranges of 25-100 mg twice daily (BID), but with significant toxicity. We conducted a retrospective cohort study of patients with advanced MF treated with low-dose duvelisib (15 mg every other day to BID), in an effort to minimize toxicity. A total of 7 patients were included. The overall response rate on duvelisib was 71%, with the remaining patients maintaining stable disease. Mean modified Severity Weighted Assessment Tool score improved by 57.4% and mean percent body surface area involved improved by 52%. Median progression-free survival was 10.3 months. Adverse events occurred in 4 of 7 patients, the most common being fatigue (2/7; grades 1-2), nausea (2/7; grades 1-2), and transaminitis (2/7; grade 3). Overall, low-dose duvelisib showed efficacy for advanced MF with less toxicity, providing a rationale for its use as monotherapy and potentially combinatorial therapy.

Oleogel-S10 in Dystrophic Epidermolysis Bullosa: A Case Series Evaluating the Impact on Wound Burden Over Two Years.

Epidermolysis bullosa (EB) is a group of rare, difficult-to-treat, inherited multisystem diseases affecting epithelial integrity. Impaired wound healing is central and can lead to serious clinical complications, deformities, and symptoms with a devastating impact on quality of life (QoL). Dressing changes and wound care are central to the management of EB. Recently Oleogel-S10 (also known as birch bark extract or birch triterpenes) was approved in Europe and the UK for treating EB wounds. This approval was based on data from the EASE phase3 study, which demonstrated Oleogel-S10 accelerated wound healing, reduced total wound burden, and decreased the frequency of dressing changes in patients with EB. A retrospective analysis of medical records was conducted for up to 24months in 13 patients with EB treated with Oleogel-S10 through an early access programme in Colombia. Effectiveness was assessed by measuring body surface area percentage (BSAP) and total body wound burden (EBDASI). Tolerability and safety were monitored throughout. This is the first report to evaluate the effectiveness of Oleogel-S10 in clinical practice. The results showed a reduction in percentage of BSA affected, from a mean of 27.3% at baseline to 10.4% at 24-month follow-up, despite treatment interruptions. A reduction in EBDASI skin activity score of - 16.2 (24months) together with a reduced skin damage index score of - 15.4 (18months) was also observed. Physicians, patients, and caregivers perceived faster wound closure. Adherence with therapy by patients was good, and patients expressed satisfaction with treatment and reported improvements in self-esteem, productivity, and social interaction. Oleogel-S10 was well tolerated; however, two patients reported worsening wounds related to gauze adherence. Two deaths during treatment interruption were reported and was not considered related to Oleogel-S10. This study supports the effectiveness of Oleogel-S10 in a real-world scenario in a country with scarce resources for the treatment of EB.

Evaluation of normal range of serum 25 hydroxyvitamin d in iraqi healthy adults: demographic and socioeconomic effects.

Aim: To determine the normal range of serum levels of total 25(OH)VD in Iraqi healthy adult subjects and to relate its level with demographic profile and socioeconomic status.. Materials and Methods: This cross sectional study was carried out at Iraq and the samples were collected during the period from August 2019 to January 2020. It included 649 adult subjects apparently healthy, from three governorates (Baghdad, Al-Anbar and Al-Basrah), Investigations included serum measurement of total 25(OH)D in all included individuals by using ELISA technique. Age, gender, marital state, blood pressure, smoking, sunshine exposure (%), hours of exposure/day, percentage of body surface area exposed, body mass index (BMI) subgroups, waist circumference (WC) subgroups, diet type, sport type and time, geographic factor (governorate) were measured and / or calculated and the levels of 25(OH)D were studied according to each of these factors. Results: The mean ± SD level of 25(OH)D in total (n=649) studied Iraqi subjects was (16.29 ± 8.22 ng/ml), with women were significantly deficient than men (15.76 ± 6.89 ng/ml, 17.14 ± 6.85 ng/ml; p < 0.01 respectively). However, there was no significant differences in mean values of serum 25(OH)D levels among studied governorates, subgroups of BMI, WC, marital status, smokers and nonsmoker and subgroups of age. The mean value of serum 25(OH)D was found to be decreased in January, October and November as well as according to diet and sport types. There was significant positive correlation between total 25(OH)D and sun exposed surface area, sun exposure duration and with sun exposure area. Conclusions: The mean (±SD) value of serum total 25(OH)D in Iraqi healthy subjects was 16.29 ng/ml (±8.22) reflecting the actual body status of this vitamin with lower concentration in women than in men. Type and time of sport and diet type were the major vitamin D dependent factors.

Outcome of Early Excision versus Delayed Excision and Grafting in Burn Less than Twenty Percent Body Surface Area

Background: Burn injuries are a significant public health concern associated with high morbidity and mortality. Surgical interventions, including early excision and grafting or delayed excision and grafting are crucial for deep burns. This study compares graft take, number of procedures, duration of stay, and burn wound infections between early excision and grafting and delayed excision and grafting groups.&#x0D; Materials and Methods: A comparative study was conducted at a burn referral center from January 1st to March 31st, 2020. Eighty-six patients (43 in each group) with deep burns covering 10-20% TBSA were included. Early excision and grafting and delayed excision and grafting groups were determined by the timing of the first operation (within or beyond 7 days post-injury). Parameters compared included graft take, number of grafting procedures, duration of stay, and graft site infection.&#x0D; Results: Both groups had a mean age of 42.6 years, with predominantly female populations. The mean total body surface area % of burn area was 15%. Early excision and grafting and delayed excision and grafting groups showed comparable outcomes in graft take (90.6% vs. 88.16%), mean duration of hospital stay (16.72 vs. 16.53 days), number of surgical procedures (1.3 vs. 1.4), and graft site infection (23.3% vs. 30.2%).&#x0D; ConclusionGraft take, duration of hospital stay, number of surgical procedures, and graft site infections were comparable in Early excision and grafting and delayed excision and grafting groups for burns covering less than twenty percent body surface area. Delay in excision and grafting did not significantly impact outcomes in smaller burns, providing valuable insights for managing delayed burn presentations.

Abstract 15758: Platelet Aggregation is Elevated in Psoriasis and Associated With Cardiovascular Risk

Introduction: Psoriasis is associated with increased CV risk the mechanisms and prevention of which are not fully known. We evaluated the platelet phenotype (implicated in atherothrombosis) and in vitro response to aspirin in patients with psoriasis and its association with vascular stiffness and coronary atherosclerosis. Methods: Patients with psoriasis (n = 64, age 47.9 ± 15 years, 65% male), percent body surface area (BSA) of psoriasis 3%, were compared to controls (n = 40, age 40.8 ± 16 years, 45% male). Percent platelet aggregation in response to agonists adenosine diphosphate (ADP), collagen (Col), and arachidonic acid (AA - with and without aspirin) was measured in freshly isolated platelet-rich plasma via light transmission aggregometry (LTA). Vascular stiffness (via pulse wave velocity [PWV]) and CT coronary angiography were each performed as readouts of CV risk. Results: Compared to controls, psoriasis patients were older, of Caucasian ethnicity (Figure 1A), and overweight, but otherwise similar. Platelet aggregation after treatment with Col (p=0.01), ADP (p &lt; 0.01), and AA (p = 0.05) were all higher in psoriasis vs. control (Figure 1B-D). Platelet aggregation after activation with high dose AA was similar between groups (Figure 1E) however co-incubation with high dose AA plus aspirin displayed incomplete platelet inhibition of psoriasis platelets vs. controls (Figure 1F). Platelet aggregation to low dose AA and high dose AA plus aspirin co-incubation were each higher in those with enhanced vascular stiffness (figure 1G/1H) and the presence of coronary plaque (Figure 1I/1J). Conclusion: Platelet aggregation is consistently elevated in psoriasis across a variety of agonists, incompletely inhibited by aspirin, and associated with biomarkers of CV risk such as vascular stiffness and the presence of coronary plaque. These findings highlight the need to evaluate various anti-platelet strategies to reduce atherothrombotic risk in patients with psoriasis.

Prevalence and predictors of vitamin D deficiency among hospital staff in tertiary care center: a cross sectional study

Background: Vitamin D deficiency (VDD) is prevalent across all age groups in general population not sparing the health care workers. This study aimed to assess the prevalence and risk factors of VDD among the hospital workers of tertiary care center in Kashmir valley. Methods: In this cross-sectional study, a total of 216 apparently healthy subjects were screened for VDD from three groups, group A- minimal sunlight exposure (office employees), group B- moderate sunlight exposure (nursing students) and group C- abundant sunlight exposure (gardeners). Serum calcium, phosphorus, alkaline phosphatase, 25-hydroxy vitamin D [25(OH)D], PTH levels and urine calcium/creatinine was assessed in all subjects. Dietary assessment of vitamin D (VD) and calcium intake was done using three days dietary recall. The percent body surface area (BSA) exposed to sunshine was estimated by applying the Wallace rule of nine. Results: Serum 25(OH)D level was found to be lower in group A (17.29±10.87) as compare to group B (21.78±16.37) and group C (26.40±15.59). Prevalence of VDD was 71.6%, 70.6% and 50% in group A, group B and group C respectively. VDD was more prevalent in females and risk increased with age and BMI, decreased with duration of daily sunlight exposure, percentage BSA and dietary VD intake. Conclusions: Burden of VDD is high among hospital workers despite their direct contact with healthcare. Strategies should be made to screen them regularly and supplementation of VD should be provided to effectively counteract VDD.

Six-Month Persistence and Multi-domain Effectiveness of Guselkumab in Adults with Psoriatic Arthritis: Real-World Data from the CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry.

The aim of this work is to evaluate treatment persistence and clinical outcomes after 6months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry. Participants with PsA who initiated and persisted with on-label guselkumab use post-Food and Drug Administration (FDA) approval for active PsA (7/13/2020; subcutaneous 100mg at weeks 0, 4, and every 8weeks) at their 6-month follow-up visit (occurring through 3/31/2023) comprised the primary analysis population (On-Label Persisters). Hierarchical, multiplicity-controlled primary and secondary outcomes were mean (95% confidence interval) changes from baseline at 6months in clinical Disease Activity Index for PsA (cDAPSA; primary), Physician Global Assessment (PGA) of arthritis and psoriasis (visual analog scale [VAS] 0-100), patient-reported pain (VAS 0-100), and percent body surface area with psoriasis (%BSA). Paired ttests determined changes that were statistically significantly different from 0 (α = 0.05). Among 114 patients who initiated on-label guselkumab and had eligible baseline and 6-month visits, 90 (78.9%) had persistent use. Among these On-Label Persisters at baseline, mean duration of PsA symptoms = 13.6years; mean cDAPSA, PGA, and patient-reported pain = 22.0, 42.3, and 57.0, respectively; 94.4% had a history of psoriasis (mean BSA 7.6%); and 18.9% and 73.3%, respectively, previously received 1 or ≥ 2 biologic/targeted synthetic disease-modifying antirheumatic drugs. The mean change (improvement) in cDAPSA was -5.4 (-8.5, -2.3; p < 0.001) at 6months. Significant mean improvements in PGA (-19.0 [-24.2, -13.8]), patient-reported pain (-9.1 [-14.4, -3.8]), and %BSA (-5.1 [-7.6, -2.7]) were also observed (all p < 0.001). In this real-world PsA population, generally characterized by longstanding, treatment-resistant, active disease at baseline, persistent guselkumab use in nearly 80% of patients with on-label use was accompanied by significant improvements in joint and skin symptoms and patient-reported pain at 6months. These registry data support results from randomized clinical trials demonstrating the efficacy of guselkumab in improving PsA signs and symptoms. clinicaltrials.gov: NCT02530268.

BG04 Oleogel-S10 (birch triterpenes) in the treatment of epidermolysis bullosa wounds: 24-month efficacy and safety data from the EASE study

Abstract Epidermolysis bullosa (EB) is a rare debilitating disorder characterized by skin fragility, blister formation and impaired wound healing. The abnormal wound healing seen in EB is a key driver for systemic disease and can lead to serious clinical complications, deformities and symptoms with a devastating impact on quality of life (QoL). The 90-day double-blind phase (DBP) of the phase III EASE study previously demonstrated accelerated wound healing for oleogel-S10 (birch triterpenes) vs. control gel in EB. Here, we report the safety and total wound burden results from the 24-month open-label phase (OLP), in which all patients received treatment with oleogel-S10. EB Disease Activity and Scarring Index (EBDASI) and body surface area percentage (BSAP) data are reported without visit windows to reflect a real-world situation more accurately, particularly considering the COVID-19 pandemic. The patient population was made up of those with dystrophic EB (n = 178; 86.8%) and junctional EB (n = 25; 12.2%). Further baseline characteristics are available in Table 1. In total, 141 patients (68.8%) completed the OLP. The mean (SD) treatment duration for all patients was 584.7 (246.1) days. Adverse events were reported in 77.1% of all patients in the OLP vs. 81.7% of those receiving oleogel-S10 in the DBP. Mean BSAP for patients treated with oleogel-S10 in the DBP reduced from 12.1% at study entry to 6.1% on completion of the EASE study. Similarly, the mean EBDASI skin activity score in the oleogel-S10 group improved from 19.6 to 15.1 at the end of the OLP. In addition, reductions in both BSAP and EBDASI from OLP baseline were observed in patients who transitioned from control gel to oleogel-S10 in the OLP. Oleogel-S10 has a reassuring long-term safety profile. Furthermore, the long-term impact of accelerated wound healing is evident through the sustained reduction in wound burden over time. This is encouraging given the regular reoccurrence of patients’ fragile wounds in the natural course of this chronic disease. Table 1Baseline characteristics

P103 A retrospective observational study of toxic epidermal necrolysis at a tertiary referral centre from 2015 to 2022

Abstract Toxic epidermal necrolysis (TEN) is associated with high mortality and morbidity. Owing to a lack of robust evidence, treatment guidelines are ambiguous and clinicians must use discretion in management decisions, specifically with regard to the use and choice of systemic agents, including immunosuppressants. We present a retrospective study of cases referred to a tertiary referral centre between 2015 and 2022. Cases were identified using histopathology coding and a database compiled by clinicians. Forty cases were categorized as follows: TEN (n = 12); Stevens–Johnson syndrome (SJS)/TEN overlap (n = 5); SJS (n = 5); unclear (n = 9); insufficient information (n = 5) and others [n = 9 (lupus, n = 4; erythema multiforme major, n = 3; burn, n = 1; recurrent erythema multiforme, n = 1)]. The median age of patients with TEN was 66 [interquartile range (IQR) 53.3–74; 33% men, 67% women]. The median percentage body surface area of epidermal loss was 40% (n = 8; IQR 30–70). Forty-two per cent of patients had an underlying malignancy. Implicated medications included nivolumab/ipilimumab (n = 2), co-trimoxazole (n = 2), carbamazepine (n = 1) and proton pump inhibitors (n = 3). Sixty-seven per cent of patients with TEN were managed by the burns centre, with a further 17% admitted to the intensive care unit. One patient presented directly to the dermatology team and 58% were transferred from other hospitals. The median time from the documented onset of rash to transfer to specialist care was 5 days (IQR 2.8–11.5). Thirty-three per cent of patients were given immunosuppression (intravenous methylprednisolone). The median duration of admission was 14 days (IQR 7.5–21.5). Fifty-eight per cent of patients (n = 7) survived. None of the five patients who died had received immunosuppression. The median time from onset of rash to receiving specialist care was 3.5 days for those who survived (n = 4) vs. 10 days for those who did not (n = 3; P = 0.03). Thirty-three per cent of patients had documented chronic complications (severe ophthalmic sequelae, n = 2; circumcision for phimosis, n = 1). This study was limited by the retrospective collection of data and the method used to identify cases. The current evidence for the treatment of TEN is primarily derived from small case series that often combine heterogeneous cases of TEN, SJS/TEN overlap and SJS. This is highly problematic as the risk–benefit dynamic varies greatly between patients with SJS, who have an excellent prognosis without treatment, and patients with TEN with a high associated mortality, who potentially have more to gain from immunosuppression. Our data support the need for patients to access specialist care promptly, to allow for early consideration of immunosuppression. Future research should focus on effective treatments for reducing mortality in cases of TEN specifically.
