Dupilumab Safety and Efficacy up to 1 Year in Children Aged 6 Months to 5 Years with Atopic Dermatitis: Results from a Phase 3 Open-Label Extension Study.

Pediatric patients with moderate-to-severe atopic dermatitis (AD) often experience a high disease burden and have a high risk of persistent disease. Standard-of-care immunosuppressive systemic treatments have been used off-label for AD in pediatric patients despite concerns for suboptimal safety with continuous use and risk of relapse upon discontinuation. The biologic agent dupilumab is the first systemic treatment approved for moderate-to-severe AD in children as young as 6 months. Long-term safety and efficacy data in this patient population are needed to inform continuous AD management. The purpose of this work was to determine the long-term safety and efficacy of dupilumab treatment up to 1 year in an open-label extension (OLE) study [LIBERTY AD PED-OLE (NCT02612454)] in children aged 6 months to 5 years with moderate-to-severe AD who previously participated in the 16-week, double-blind, phase 3 LIBERTY AD PRESCHOOL trial (NCT03346434 part B; parent study) and were subsequently enrolled in PED-OLE. In PED-OLE, patients received dupilumab every 4 weeks according to a weight-tiered regimen (body weight ≥ 5 kg to < 15 kg: 200 mg; ≥ 15 kg to < 30 kg: 300 mg). Data for 142 patients were analyzed, 60 of whom had completed the 52-week visit at time of database lock. Mean age at baseline was 4.1 y [SD, 1.13; range, 1.0-5.9 years]. A majority (78.2%) of patients reported ≥ 1 treatment-emergent adverse event (TEAE), most of which were mild or moderate and transient. The most frequently reported TEAEs were nasopharyngitis (19.7%), cough (15.5%), and pyrexia (14.1%). One TEAE led to treatment discontinuation (severe urticaria, which resolved in 1 day). By week 52, 36.2% of patients had achieved an Investigator's Global Assessment score of 0/1 (clear/almost clear skin), and 96.6%, 79.3%, and 58.6% had at least 50%, 75%, or 90% improvement, respectively, in Eczema Area and Severity Index scores. Consistent with results seen in adults, adolescents, and older children (aged 6-11 years), treatment with dupilumab for up to 1 year in children aged 6 months to 5 years with inadequately controlled moderate-to-severe AD demonstrated an acceptable long-term safety profile and sustained efficacy. These results support the long-term continuous use of dupilumab in this patient population. ClinicalTrials.gov Identifiers: NCT02612454 and NCT03346434 (part B).

Preventing postpartum insomnia: findings from a three-arm randomized-controlled trial of cognitive behavioral therapy for insomnia, a responsive bassinet, and sleep hygiene.

Insomnia symptoms are common during the perinatal period and are linked to adverse outcomes. This single-blind three-arm randomized-controlled trial examined whether two interventions targeting different mechanisms prevent postpartum insomnia. Participants were nulliparous females 26-32 weeks gestation with Insomnia Severity Index (ISI) scores ≥ 8, recruited in Australia and randomized 1:1:1 to: (1) a responsive bassinet (RB) designed to support infant sleep and reduce maternal sleep disruption until 6 months postpartum, (2) therapist-assisted cognitive behavioral therapy for insomnia (CBT-I) delivered during pregnancy and postpartum, or (3) a sleep hygiene booklet (control; CTRL). Outcomes were assessed at baseline (T1), 35-36 weeks gestation (T2), and 2, 6, and 12 months postpartum (T3-T5). The primary outcome was ISI scores averaged T3-T5. Primary analyses were regressions controlling for baseline outcomes. One hundred and twenty-seven participants (age M ± SD = 32.62 ± 3.49) were randomized (RB = 44, CBT-I = 42, CTRL = 41). Both interventions were feasible and well-accepted, with few related adverse events reported. Compared to CTRL, the average ISI across T3-T5 was lower for CBT-I (p = .014, effect size [ES] = 0.56, medium) but not RB (p = .270, ES = 0.25, small). Exploratory findings on maternal insomnia diagnosis, sleep disturbance, sleep-related impairment, beliefs and attitudes about sleep, depression, anxiety, as well as infant sleep outcomes were also presented. CBT-I but not RB reduced prenatal insomnia (very large effect) and prevented postpartum insomnia (medium effect). Further research is needed to examine the effects of both CBT-I and RB on other outcomes such as sleep-related well-being, postpartum depression, and maternal postpartum sleep duration.

Rapid and sustained improvement of psoriasis with Bimekizumab: A real‐world case series

AbstractThis retrospective case series examines the efficacy and safety of Bimekizumab in 22 patients with moderate to severe plaque psoriasis in a real‐world clinical setting. The demographic and clinical characteristics of the participants, including a mean age of 43.7 years and a gender distribution of 60% male and 40% female, are summarised. Notably, 70% of the patients had previously received systemic therapy, and 50% had concurrent psoriatic arthritis. The evaluation over a 12‐week treatment period revealed a significant reduction in psoriasis area and severity index scores from a baseline mean of 11.5−1.0 at Week 4 and further down to 0.3 by Week 12. Similar improvements were observed in body surface area, physician's global assessment and dermatology life quality index scores. Bimekizumab was well‐tolerated with no reported adverse events, leading to no treatment discontinuations. These findings highlight the potential of Bimekizumab to provide rapid and sustained improvements in patients with moderate to severe plaque psoriasis, underlining its value in clinical practice.

Plexin B2 tissue expression and related gene polymorphisms in psoriasis and their relation to NB-UVB and Acitretin therapy

Psoriasis is a chronic, immune-mediated, hyperproliferative skin disease. Etiopathogenesis of psoriasis is not well understood. Plexin B2 was found to have effects on CD100-mediated T-cell morphology and expressed in the immune system. It may play a role in the pathogenesis of psoriasis. To assess the tissue level of plexin-B2 and plexin B2 related gene polymorphism which is signal regulatory protein gamma (SIRPγ-rs71212732) in psoriatic patients before and after NB-UVB, acitretin therapy alone or in combination and to detect correlation between level of tissue plexin B2 and disease severity and improvement. This single blinded randomized controlled trial was carried on 50 psoriatic patients and 50 healthy controls. Psoriasis Area and Severity Index score (PASI) was used to evaluate the disease severity. Tissue plexin-b2 level was measured using ELISA and SIRPγ-rs71212732 (T\\C) was assessed using TaqMan™ assays and real-time PCR. A significant lower tissue plexin-B2 level was observed in control group (2.9 ± 0.6 pg/g) than cases (25.8 ± 2.8, pg/g) (p < 0.001). Also, a significantly higher tissue plexin-B2 level was observed in sever psoriasis (32.7 ± 3.8 pg/ml) in than moderate psoriasis (13.6 ± 2.1 pg/ml, p = 0.001). Tissue plexin B2 was positively correlated with diseases severity. Significantly higher (TC& TT) genotypes and mutant (C) allele among patients compared to the controls, p < 0.001 for all. Tissue plexin-b2 level was high in psoriasis vulgaris with positive correlation with disease severity and decreased after treatment. This may indicate a role of plexin-b2 in psoriasis vulgaris pathogenesis.

Efficacy and safety of dupilumab with concomitant topical corticosteroids in Japanese pediatric patients with moderate-to-severe atopic dermatitis: A randomized, double-blind, placebo-controlled phase 3 study

BackgroundWe investigated the efficacy and safety of dupilumab in Japanese patients aged ≥6 months to <18 years old with moderate-to-severe atopic dermatitis not adequately controlled with existing therapies. MethodsIn this randomized, double-blind, phase 3 study, patients received dupilumab (n = 30) or placebo (n = 32) with concomitant topical corticosteroids for 16 weeks, then all patients received dupilumab from 16 to 52 weeks. The primary endpoint was the proportion of patients with ≥75% improvement in Eczema Area and Severity Index (EASI) score from baseline (EASI-75) to Week 16. Key secondary endpoints included changes in EASI score, proportion of patients with investigator global assessment (IGA) scores of 0/1, and changes in worst daily itch numerical rating scale (NRS) scores (evaluated in patients aged ≥6 to <12 years [n = 35]). ResultsAt Week 16, more patients achieved EASI-75 with dupilumab than placebo (43.3% vs 18.8%; P = 0.0304), and the least squares mean (LSM) difference in percent change in EASI scores at Week 16 of dupilumab vs placebo was –39.4% (P = 0.0003). However, no significant difference in the proportion of patients achieving IGA scores of 0/1 at Week 16 with dupilumab versus placebo were seen (10.0% vs 9.4%; P = 0.8476). The percent change in worst daily itch NRS scores at Week 16 was higher with dupilumab (LSM difference: –33.3%; nominal P = 0.0117). Dupilumab was well tolerated; no new safety signals were identified. ConclusionsDupilumab showed consistent efficacy and was well tolerated in Japanese patients aged ≥6 months to <18 years with moderate-to-severe atopic dermatitis previously insufficiently controlled with existing therapies.

Risk factors for in-hospital acquisition of carbapenem-resistant Enterobacterales in patients with severe burns

Although patients with severe burns are prone to severe infections with antibiotic-resistant bacteria and inevitably have some risk factors for carbapenem-resistant Enterobacterales (CRE) acquisition, risk factors for CRE infection or colonization in these patients have not been investigated. To identify the independent risk factors for CRE acquisition in patients with severe burns. Patients admitted to the burn intensive care unit (BICU) for acute burn care were categorized based on culture results during BICU care into the CRE group and non-CRE group, which included the carbapenem-susceptible Enterobacterales (CSE) and control groups. Clinical and microbiological factors were compared between the CRE and non-CRE groups, and between the CRE and CSE groups to identify independent risk factors for in-hospital CRE acquisition. Among the included 489 patients, 101 (20.7%) and 388 (79.3%) patients were classified in the CRE and non-CRE groups, respectively. The non-CRE group included 91 (18.6%) and 297 (60.7%) patients in the CSE and control groups, respectively. In multivariate analysis between the CRE and non-CRE groups, exposure to other CRE-acquired patients (P= 0.018), abbreviated burn severity index score ≥9 (P= 0.012), and mechanical ventilation (P < 0.001) were associated with CRE acquisition. In multivariate analysis between the CRE and CSE groups, exposure to other CRE-acquired patients was associated with CRE acquisition (P= 0.048). Considering the limitation of controlling the burn severity in hospitalized patients, enhanced infection control measures for preventing in-hospital CRE transmission among patients with severe burns should be emphasized.

Insomnia severity among caregivers of children with type 1 diabetes: A mixed method study

AimThis research was conducted to assess the severity of insomnia experienced by caregivers of children with type 1 diabetes. MethodIn this study, a mixed-method descriptive sequential pattern design was employed, incorporating both qualitative and quantitative research methods. In the study, 152 caregivers were surveyed for quantitative data on survey form and insomnia severity. Additionally, 9 mothers underwent semi-structured interviews for qualitative insights. ResultsOf caregivers, 13.8% were identified to experience clinical insomnia. There were statistically significant differences in insomnia severity index scores in terms of experiencing sleep problems after the child's type 1 diabetes diagnosis, caregivers having adequate sleep duration at night, how they felt on waking in the morning, difficulty managing their child's diabetes the next day due to lack of sleep, difficulty getting to sleep at night, sleeping more than one hour during the day, lack of sleep due to caring and treatment, lack of sleep due to not meeting the desired targets for blood glucose values and receiving support for type 1 diabetes management due to lack of sleep (p < 0.05). Three themes were identified as a result of qualitative analysis: Sleep status of caregivers, effect of sleep problems on daily life and solving sleep problems. ConclusionsCaregivers experience insomnia during the process of type 1 diabetes management and this situation affects their daytime care duties. Practical implicationsResearch shows caregivers of children with type 1 diabetes often face insomnia, highlighting the need for solutions.

Body mass index and long-term survival following acute pulmonary embolism: insights from machine learning models

Abstract Funding Acknowledgements None. Introduction Body mass index (BMI) has been associated with long-term survival in the setting of acute pulmonary embolism (PE) [1,2]. The non-linear pattern of this association proves to be challenging for frequentist statistical analyses. Contemporary machine learning models offer superior handling capabilities of datasets with non-linear data distributions. Purpose To examine the predictive power of BMI expressed as a continuous variable in a dataset of patients with pulmonary embolism (PE) using the extreme gradient boosting (XGBoost) machine learning framework. Methods All consecutive patients with confirmed PE admitted to the two tertiary teaching Clinical Hospitals in the metropolitan area from November 2013 until November 2018 were included in the study. The diagnosis was established by multislice computed tomography angiography. Machine learning models were investigated using the LightGBM variant of XGBoost. We allocated 80% of the dataset for model training and the remaining 20% for testing. Two models were tested: (1) a model with 20 variables tailored according to the Cox proportional hazards model in the initial publication; (2) a model with 11 independent predictors of outcome. Results The study population is described in detail in previous publications [1,2]. In brief, a total of 761 patients were included in the study. The population was predominantly female (57.4%), aged 73 (61-81). The median overall follow-up was 675 days (114-1331). There were 335 (44.0%) cases of death recorded at follow-up. A Cox proportional hazards model with 19 covariates significantly predicted death during follow-up (χ2 = 595.5, p&amp;lt;0.001). The first BMI quartile was an independent predictor of death (hazard ratio 1.66, 95% confidence interval 1.31-2.10). However, when expressed as a continuous variable, BMI failed to enter the model. In both XGBoost models, BMI expressed as a continuous variable proved to be a feature with high predictive power, second only to pulmonary embolism severity index score (Figure 1 and 2). The models showed high accuracy, with an area under curve of 0.840 and 0.864 respectively. Conclusion In the XGBoost analysis, a machine learning framework with superior handling of non-linear data, BMI expressed as a continuous variable emerged as the second strongest predictor of outcome among 761 PE patients.Figure 1Figure 2

Reperfusion therapies in patients with intermediate- and high-risk pulmonary embolism: insights from a multicenter registry

Abstract Funding Acknowledgements None. Background Most acute pulmonary embolism (PE) patients receive anticoagulation as a sole treatment. Reperfusion therapies are required in high-risk (HR) and in intermediate-risk (IR)-PE patients with clinical deterioration. Systemic thrombolysis (ST) is the first-line reperfusion therapy, but due to contraindications and major bleeding concerns, catheter-directed therapies (CDT) are rising as a suitable alternative. Purpose The main objective of this study was to look for predictors that lead physicians to decide between different PE therapies in a contemporary cohort of patients. Methods This ambispective registry included consecutive IR- and HR-acute PE patients evaluated by local Pulmonary Embolism Response Team in two tertiary centers from 2014 to 2022. The patients were grouped according to the elected therapy: anticoagulation alone, CDT or ST. If more than one reperfusion therapy was used, the patient was assigned to the group of the first administered therapy. Predictors of reperfusion therapy assignment were evaluated using a logistic regression analysis. Also, early safety outcomes and procedural results after CDT were analyzed. Results A total of 274 patients were included. Of them, 112 received only anticoagulation, 96 received ST as primary treatment, and 66 underwent CDT at first. Baseline characteristics are displayed in Picture 1. Patients in the ST group were significantly younger (p&amp;lt;0.01). Comorbidities were higher in the CDT group compared to the other two. Patients undergoing CDT or ST had higher PE severity parameters at hospital admission than the anticoagulation group (e.g. shock index, RV involvement, or lactate levels; p&amp;lt;0.01 for all). The Pulmonary Embolism Severity Index score, which incorporates comorbidities and PE severity parameters, was higher in CDT patients compared to the other two groups (p&amp;lt;0.01). Picture 2 shows the trend in the choice between the two primary reperfusion therapies over the years. After multivariable analysis, the Charlson comorbidity index, recent surgery and bilateral central PE remained independent predictors for the use of CDT instead of ST (p&amp;lt;0.05 for all). A significant decrease in the systolic and mean pulmonary artery pressure and a significant increase in systolic blood pressure after procedure was detected in patients undergoing CDT. Regarding early safety outcomes, intracranial bleeding occurred only in the ST group. In contrast, the incidence of major bleeding, acute kidney injury and 30-day mortality did not differ between CDT and ST groups. Conclusion This contemporary registry used CDT as primary therapy in 24% of IHR and HR patients, mainly in comorbid and post-surgical patients, and increased over time. CDT was a safe and effective alternative to ST, achieving significant and early improvement in right ventricular function and hemodynamics.Baseline characteristicsChoice of reperfusion therapy over time

Instability Severity Index Score predicts recurrent shoulder instability after arthroscopic Bankart repair.

The Instability Severity Index (ISI) Score was developed to preoperatively assess the risk of recurrent shoulder instability after an arthroscopic Bankart repair. This study aims to validate the use of ISI Score for predicting the risk of recurrence after an arthroscopic Bankart repair in a heterogeneous population and proposes an appropriate cut-off point for treating patients with an arthroscopic Bankart repair or otherwise. This study analysed 99 shoulders after a traumatic dislocation that underwent arthroscopic Bankart repair with at least 3 years follow-up. Patients were divided into subcategories based on their respective ISI Score. Recurrence includes either a postoperative dislocation or perceived instability. The overall recurrence rate was found to be 26.3%. A significant correlation was identified between ISI Score and the recurrence rate (odds ratio [OR]: 1.545, 95% confidence interval [CI]: 1.231-1.939, p < 0.001). Furthermore, ISI Score 4-6 (OR: 4.498, 95% CI: 1.866-10.842, p < 0.001) and ISI Score > 6 (OR: 7.076, 95% CI: 2.393-20.924, p < 0.001) both had a significantly higher risk of recurrence compared to ISI Score 0-3. In ISI Score subcategories 0-3, 4-6 and >6, the recurrence rate was, respectively, 15.4%, 40.7% and 71.4%. ISI Score has predictive value in determining the recurrence risk of shoulder instability following an arthroscopic Bankart repair in a heterogeneous population. Based on the findings of this study, we recommend using arthroscopic Bankart repair in patients with ISI Score 0-3. Clinical and shared decision-making are essential in the group with ISI Score 4-6, since the recurrence rate is significantly higher than in patients with ISI Score 0-3. Arthroscopic Bankart repair is not suitable for patients with ISI Score > 6. Level III.

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.

Identification of the immune repertoire of γδ T-cell receptors in psoriasis.

The γδ Tcells are a subpopulation of Tcells that are abundantly found in the skin and mucous membranes. Their reactivity to self-antigens and ability to secrete various cytokines make them a key component in psoriasis development. Although the correlation between the immune repertoire (IR) of γδ T-cell receptors and the occurrence and severity of psoriasis remains incompletely explored, high-throughput sequencing of γδ Tcells has led to a deeper understanding of IR in psoriasis. This study investigated the differences between γδ Tcells in patients with psoriasis and healthy controls. The γδ Tcells were identified via immunofluorescence staining and a correlation analysis was performed according to the psoriasis area and severity index (PASI) scores. The IR sequencing method was used to detect IR in the γδ T-cell receptors. The findings demonstrated more skin γδ Tcells in patients with psoriasis, which were positively correlated with the PASI score. There were subtle differences in most variable (V), diversity (D) and joining (J) gene segments and VJ/VDJ combination segments between patients with psoriasis and healthy controls. However, a higher diversity of complementarity-determining region 3 (CDR3) was observed in patients with psoriasis. In summary, the IR of skin γδ Tcells was significantly altered in patients with psoriasis, and the diversity in the cell's CDR3 population is a promising biomarker for assessment of psoriasis severity.

Cornuside alleviates psoriasis-like skin lesions in mice by relieving inflammatory effects

Psoriasis is a chronic inflammatory skin disease substantially affecting the quality of life, with no complete cure owing to its complex pathogenesis. Cornuside, a major bioactive compound present in Cornus officinalis Sieb. et Zucc., which is a well-known traditional Chinese medicine with a variety of biological and pharmacological activities, such as anti-apoptotic, antioxidant, and anti-inflammatory properties. However, its effects on psoriasis remain unclear. Our preliminary analysis of network pharmacology showed that cornuside may be involved in psoriasis by regulating the inflammatory response and IL-17 signaling pathway. Thus, we investigated the protective role and mechanism of cornuside in the pathogenesis of psoriasis in an imiquimod (IMQ)-induced psoriasis mouse model. In-vivo experiments demonstrated that cornuside-treated mice had reduced skin erythema, scales, thickness, and inflammatory infiltration. The Psoriasis Area Severity Index score was significantly lower than that of the IMQ group. Flow cytometry analysis indicated that cornuside effectively inhibited Th1- and Th17-cell infiltration and promoted aggregation of Th2 cells in skin tissues. Cornuside also inhibited the infiltration of macrophages to the skin. Furthermore, in-vitro experiments indicated that cornuside also decreased the polarization of M1 macrophages and reduced the levels of associated cytokines. Western blotting demonstrated that cornuside suppressed the phosphorylation of c-Jun N-terminal kinase (JNK) and extracellular receptor kinase (ERK) in bone marrow-derived macrophages. Our findings indicate that cornuside has a protective effect against IMQ-induced psoriasis by inhibiting M1 macrophage polarization through the ERK and JNK signaling pathways and modulating the infiltration of immune cells as well as the expression of inflammatory factors.

Eosinophilia Is a Favorable Marker for Pneumonia in Chronic Obstructive Pulmonary Disease.

Patients with chronic obstructive pulmonary disease (COPD) expressing eosinophilia experience slightly fewer episodes of community-acquired pneumonia (CAP), than those without eosinophilia. However, the severity and burden of hospitalized pneumonia patients with COPD involving eosinophilia have not been assessed. We evaluated the differences in clinical characteristics between patients with CAP and COPD with or without eosinophilia by a post hoc analysis of a prospective, multi-center, cohort study data. Of 349 CAP patients with COPD, 45 (12.9%) had eosinophilia (blood eosinophil ≥300 cells/μL). Patients with eosinophilia had a lower sputum culture percentile (8.1% vs. 23.4%, p&lt;0.05), a lower percentile of neutrophils (70.3% vs. 80.2%, p&lt;0.05), reduced C-reactive protein levels (30.6 mg/L vs. 86.6 mg/L, p&lt;0.05), and a lower pneumonia severity index score (82.5 vs. 90.0, p&lt;0.05), than those without eosinophilia. The duration of antibiotic treatment (8.0 days vs. 10.0 days, p&lt;0.05) and hospitalization (7.0 days vs. 9.0 days, p&lt;0.05) were shorter in eosinophilic patients. The cost of medical care per day (256.4 US$ vs. 291.0 US$, p&lt;0.05), cost for the medication (276.4 US$ vs. 349.9 US$, p&lt;0.05), and cost for examination (685.5 US$ vs. 958.1 US$, p&lt;0.05) were lower in patients with eosinophilia than those without eosinophilia. Eosinophilia serves as a favorable marker for the severity of pneumonia, health-care consumption, and cost of medical care in patients with CAP and COPD.

Effect of Intense Pulsed Light versus Intradermal Tranexamic Acid for the Management of Melasma.

To compare the effectiveness of intense pulsed light (IPL) and intradermal tranexamic acid (TXA) in treating melasma. A cross-sectional analytical study. Place and Duration of the Study: Department of Dermatology, Dow International Medical College, Dow University Hospital, Karachi, Pakistan, from 15th January to 15th July 2023. A total of 62 patients with melasma, aged 20-50 years, were divided into two groups. Group A (32 patients) received IPL (560 nm filter was used) treatment, and Group B (30 patients) received intradermal TXA. Each group underwent four treatment sessions with varying intervals. Melasma area and severity index (MASI) scores were used to compare the effects of treatment. After a 3-month treatment period, both groups showed reduced mMASI scores compared to baseline with a significant initial difference between Group A (8.6 ± 4.2) and Group B (5.4 ± 2.7, p <0.001). However, post-treatment, there was no significant difference in mMASI scores (Group A: 3.8 ± 2.6; Group B: 3.2 ± 2.0, p = 0.29). IPL treatment (Group A) demonstrated a significant reduction in mMASI scores (57.1 ± 19.7) compared to intradermal TXA treatment (Group B, 42.2 ± 18.8, p = 0.0034). Both IPL and intradermal TXA treatments effectively reduced melasma, with IPL exhibiting superior results. However, post-treatment outcomes converged, emphasising the need for personalised approaches considering the unique characteristics of South East Asian skin.

Potential Usefulness of Lifetime Globotriaosylsphingosine Exposure at Diagnosis and Baseline Modified Disease Severity Score in Early-Diagnosed Patients With Fabry Disease.

Fabry disease (FD) is a lysosomal storage disease caused by a deficit of α-galactosidase A (GAL). Recently, plasma globotriaosylsphingosine (lyso-Gb3), a pathogenic analog of a substrate of GAL, has been suggested as a potential biomarker for FD, and disease severity scores, such as the Mainz Severity Score Index (MSSI), the Disease Severity Scoring System (DS3), and FASTEX (FAbry STabilization indEX), are useful tools for evaluating the severity of signs and symptoms in symptomatic FD patients. However, a more useful method of evaluating disease severity in early-diagnosed FD patients such as children, adult females, and asymptomatic patients is needed. Here, we proposed modified MSSI and DS3 scores to which we added phenotype, urinary mulberry bodies, and history of past pain attacksand examined the clinical usefulness of lyso-Gb3 and modified scores for early-diagnosed FD patients. In 13 early-diagnosed FD patients, we developed modified MSSI and DS3 scores and examined the correlation of lifetime lyso-Gb3 exposure at diagnosis with the conventional or modified scores.Lifetime lyso-Gb3 exposure was positively correlated only with the modified DS3 score. Additionally, we examined the long-term changes in plasma lyso-Gb3 concentration and in conventional MSSI, DS3, and FASTEX. In males, plasma lyso-Gb3 concentration decreased more rapidly than in females. In all patients, the severity scores were mild and remained nearly stable throughout the follow-up period. Our data suggest that lifetime lyso-Gb3 exposure and the modified DS3 score are useful in early-diagnosed patients.

Bimekizumab for the Treatment of Plaque Psoriasis with Involvement of Genitalia: A 16-Week Multicenter Real-World Experience - IL PSO (Italian Landscape Psoriasis).

Genital involvement is observed in approximately 60% of patients with psoriasis, presenting clinicians with formidable challenges in treatment. While new biologic drugs have emerged as safe and effective options for managing psoriasis, their efficacy in challenging-to-treat areas remains inadequately explored. Intriguingly, studies have shown that interleukin (IL)-17 inhibitors exhibit effectiveness in addressing genital psoriasis. We aimed to determine the effectiveness profile of bimekizumab in patients affected by moderate-to-severe plaque psoriasis with involvement of genitalia. Bimekizumab, a dual inhibitor of both IL-17A and IL-17F, was the focus of our 16-week study, demonstrating highly favorable outcomes for patients with genital psoriasis. The effectiveness of bimekizumab was evaluated in terms of improvement in Static Physician Global Assessment of Genitalia (sPGA-G) and Psoriasis Area and Severity Index. Sixty-five adult patients were enrolled. Remarkably, 98.4% of our participants achieved a clear sPGA-G score (s-PGA-g = 0) within 16 weeks. Moreover, consistent improvements were observed in Psoriasis Area and Severity Index scores, accompanied by a significant reduction in the mean Dermatology Life Quality Index, signifying enhanced quality of life. Notably, none of the patients reported a severe impairment in their quality of life after 16 weeks of treatment. In our cohort of 65 patients, subgroup analyses unveiled that the effectiveness of bimekizumab remained unaffected by prior exposure to other biologics or by obesity. Our initial findings suggest that bimekizumab may serve as a valuable treatment option for genital psoriasis. Nevertheless, further research with larger sample sizes and longer-term follow-up is imperative to conclusively validate these results.

Botulinum toxin injection shows promise in nail psoriasis: A comparative randomized controlled trial

Nail psoriasis remains a challenging condition with limited satisfaction from current treatments. An increasing number of neuropeptides were reported in psoriatic tissue. To compare the efficacy of botulinum toxin A (BoNT-A) injection, triamcinolone acetonide (TA) injection, topical combination of vitamin D/steroid (VitD/steroid) and placebo in improving nail psoriasis. A 24-week randomized intraindividual comparative-controlled study involved participants with at least 4 psoriatic fingernails, each with a total target nail psoriasis severity index (NAPSI) score of at least 3 points. Nails were randomly received different treatments; intralesional BoNT-A injection at baseline, intralesional TA at baseline and eighth week, daily topical VitD/steroid application for 16weeks and placebo. Evaluation of 64 psoriatic fingernails showed a 40% reduction in the total target NAPSI score at 24weeks following BoNT-A injection (P=.001). BoNT-A significantly improved nail bed lesions more than TA and topical VitD/steroid (P=.038), with no reported serious adverse effects. Relatively small sample size; hand hygiene during the COVID-19 pandemic may interfere NAPSI score evaluation. BoNT-A injection emerges as a promising and effective therapy for nail psoriasis, providing sustained efficacy lasting up to 6months with a single injection.

Efficacy of Intralesional Methotrexate Injection versus Triamcinolone Acetonide in Nail Psoriasis: A-Systematic Review and Meta-Analysis

Introducion: Psoriasis is a chronic inflammatory skin disease that can affect many parts of the body. Psoriatic involvement of the nail bed or nail matrix results in nail psoriasis that is common. Patients with psoriatic nails have impaired quality of life due to the appearance of nails, and significant morbidity and functional impairments may arise in large cases. The management of nail psoriasis is challenging because it is usually time-consuming with unsure outcomes. The existing evidences suggest that intralesional injection are particularly effective for nail psoriasis. Current studies provide recommendations on the intralesional injection technique, recommending an optimal concentration of methotrexate (MTX), triamcinolone acetonide (TA), and cyclosporine but the comparison of these treatment was still limited. Objective: This study aimed to evaluate the efficacy of intralesional injections of MTX compared with TA in treating nail psoriasis using Nail Psoriasis Severity Index (NAPSI) score. Methods: A systematic literature search was performed using EBSCOhost, Scopus, ProQuest, ScienceDirect, SpringerLink, Elsevier Clinical Key, Cochrane library, ClinicalTrials.gov subgroups terms: “intralesional methotrexate injections for nail psoriasis”, “intralesional triamcinolone acetonide injections for nail psoriasis” and “NAPSI Score”. Three studies were included in the qualitative synthesis and meta-analysis. Results: The overall SMD in NAPSI scores after administration of intralesional injection of MTX and TA was -0.213±0.232 (95% CI = -0.667 to 0.241). The Q statistic value was -0.921 (p=0.357), indicating the insignificant difference in the effectiveness of both therapies. Conclusion: Both MTX and TA were effective in treating nail psoriasis based on the reduction of NAPSI score.
