RESUMO
Psoriasis is a chronic complicated inflammatory skin disease. Genital, nail, and scalp lesions with psoriasis are difficult-to-treat and significantly impair patients' quality of life (QOL). Deucravacitinib, a selective oral tyrosine kinase 2 (TYK2) inhibitor, may act as a novel therapeutic option that improves these challenging manifestations. A retrospective study was conducted from January 2023 and February 2024 on 70 psoriasis patients treated with deucrabacitinib 6 mg. We evaluated the achievement rates of genital physician's global assessment (genital-PGA) 0/1, PGA of fingernails (PGA-F) 0/1, scalp-specific PGA (ss-PGA) 0/1, whole-body static PGA (sPGA) 0/1, and dermatology life quality index (DLQI) 0/1 at weeks 4, 16, and 24. Deucravacitinib improved genital, nail, and scalp lesions as well as systemic eruption and QOL in patients with psoriasis. Deucravacitinib may act as a promising treatment option for these difficult-to-treat lesions with psoriasis.

Psoriasis is a chronic skin disease with interleukin (IL)-17-dominated inflammation and hyperproliferation of epidermis. Dietary fiber is fermented by the gut microbiome into short-chain fatty acids (SCFAs) that manifest anti-inflammatory effects. We examined if feeding with an inulin-enriched high-fiber diet (HFD) might improve topical imiquimod-induced psoriasis-like dermatitis in mice. HFD reduced thickening and total severity scores of imiquimod-induced dermatitis and reduced epidermal thickness, inflammatory infiltrates, including Ly6G+ neutrophils, and epidermal Ki67+ proliferating cells. HFD reduced mRNA levels of IL-17A, IL-17F, IL-22, IL-1ß, tumor necrosis factor (TNF)-α, CXCL1, CXCL2, and keratin 16 and increased those of transforming growth factor (TGF)-ß1 and cyclin-dependent kinase inhibitor 1A in imiquimod-induced dermatitis. In 16S rRNA sequencing of the gut microbiome, imiquimod increased relative abundance of phylum Firmicutes, while HFD increased that of phylum Bacteroidota and genus Bacteroides. HFD increased serum and fecal concentrations of SCFA propionate. Oral propionate reduced inflammatory infiltrates and epidermal Ki67+ cells and reduced mRNA levels of IL-17A, IL-17F, IL-17C, IL-22, IL-1ß, IL-6, TNF-α, CXCL1, CCL20 and increased those of TGF-ß1and IL-10 in imiquimod-indued dermatitis. Dietary inulin supplementation improves imiquimod-induced psoriasis-like dermatitis partially via propionate, and may be a promising adjunctive therapy for psoriasis.

Among human cutaneous malignancies, basal cell carcinoma is the most common. Solid advances in unveiling the molecular mechanisms of basal cell carcinoma have emerged in recent years. In Gorlin syndrome, which shows basal cell carcinoma predisposition, identification of the patched 1 gene (PTCH1) mutation was a dramatic breakthrough in understanding the carcinogenesis of basal cell carcinoma. PTCH1 plays a role in the hedgehog pathway, and dysregulations of this pathway are known to be crucial for the carcinogenesis of many types of cancers including sporadic as well as hereditary basal cell carcinoma. In this review, we summarize the clinical features, pathological features and hedgehog pathway as applied in basal cell carcinoma. Other crucial molecules, such as p53 and melanocortin-1 receptor are also discussed. Due to recent advances, therapeutic strategies based on the precise molecular mechanisms of basal cell carcinoma are emerging. Target therapies and biomarkers are also discussed.

BACKGROUND: Dupilumab, a fully human monoclonal antibody that blocks signalling pathways of interleukin (IL)-4 and IL-13, is effective in treating patients with atopic dermatitis (AD). We previously showed that transitions of serum thymus and activation-regulated chemokine (TARC) levels and eosinophil numbers were strongly associated with that of AD activity and that the transitions of serum lactate dehydrogenase (LDH) and immunoglobulin E (IgE) levels were weakly and not associated with that of AD activity, respectively, in patients treated without dupilumab. OBJECTIVES: The purpose of this study was to elucidate whether the association of the transition of laboratory marker levels and transition of disease activity in dupilumab-treated AD patients (present study) was different from that in patients who are not treated with dupilumab (previous study). METHODS: Sixty AD outpatients treated with dupilumab were included in this study. Associations between the transition of the eczema area and severity index (EASI) score and those of above-mentioned laboratory marker levels were evaluated using a mixed effects model of EASI as the response variable, laboratory markers as fixed effects and patients as random effects. RESULTS: The transitions of serum TARC and LDH levels were associated strongly with that of AD activity, but the transitions of serum IgE level and eosinophil numbers were associated with that of AD activity intermediately and weakly, respectively. CONCLUSIONS: Laboratory markers are useful for evaluating the effects of treatments for AD, but the meaning of each laboratory marker depends on the drugs used for treatment.

Psoriasis is a chronic inflammatory skin disease characterized by IL-17-dominant abnormal innate and acquired immunity, and the hyperproliferation and aberrant differentiation of epidermal keratinocytes, and comorbid arthritis or cardiometabolic diseases. This Special Issue presented updated information on pathogenesis, comorbidities, and therapy of psoriasis. The pathogenesis of psoriasis may involve the dysfunction of indoleamine 2,3-dioxygenase 2 or of UBA domain containing 1-mediated regulation of CARD14/CARMA2sh. The blood cells of psoriasis patients showed the enhanced oxidative stress/autophagy flux and decreased 20S proteasome activity. Elafin, clusterin, or selenoprotein P may act as biomarkers for psoriasis and comorbid metabolic diseases. The proteomic profile of psoriasis lesions showed the dysfunction of dermal fibroblasts; up-regulation of proinflammatory factors and signal transduction or down-regulation of structural molecules. The skin inflammation in psoriasis may populate certain gut bacteria, such as Staphylococcus aureus and Streptococcus danieliae, which worsen the skin inflammation in turn. The psoriasis-associated pruritus may be caused by immune, nervous, or vascular mechanisms. In addition to current oral treatments and biologics, a new treatment option for psoriasis is now being developed, such as retinoic-acid-receptor-related orphan nuclear receptor γt inhibitors, IL-36 receptor antagonist, or aryl hydrocarbon receptor agonist. Antimicrobial peptides and innate immune cells, involved in the pathogenesis of psoriasis, may be novel therapeutic targets. The pathomechanisms and responses to drugs in collagen diseases are partially shared with and partially different from those in psoriasis. Certain nutrients can exacerbate or regulate the progress of psoriasis. The articles in this Special Issue will encourage attractive approaches to psoriasis by future researchers.

We report the case of a 59-year-old Japanese woman who developed linear IgA bullous dermatosis during treatment for ulcerative colitis that manifested as pruritic vesicles with erythema on the trunk and scalp. Histopathological examination revealed subepidermal bulla with neutrophil and eosinophil infiltration in the upper dermis. Direct immunofluorescence revealed linear IgA deposits at the basement membrane zone, and indirect immunofluorescence using split skin revealed IgA reaction to the epidermal side (lamina lucida type). We reviewed 33 reported cases of linear IgA bullous dermatosis associated with ulcerative colitis and found that ulcerative colitis preceded the onset of linear IgA bullous dermatosis in 94% of the patients and that IgA-positive patients in split skin indirect immunofluorescence all showed the lamina lucida type, indicating that target antigens for serum IgA antibodies may reside in the lamina lucida. Regarding the pathogenetic association of ulcerative colitis and linear IgA bullous dermatosis, intestinal inflammation may induce the exposure and presentation of intestinal antigens that are cross-reactive to cutaneous antigens, stimulating autoimmune response to antigens of cutaneous basement membrane zones.

BACKGROUND: Chronic spontaneous urticaria (CSU) is defined as the spontaneously appearing weals and/or angioedema for more than 6 weeks. Dietary habits can modulate the pathogenesis of CSU. However, dietary intakes of nutrients or food in CSU patients, compared with healthy controls, have not been examined in quality and quantity. METHODS: We evaluated dietary habits in adult Japanese patients with chronic spontaneous urticaria using a validated, brief-type self-administered diet history questionnaire and compared the results to those of age- and sex-matched healthy controls. The severity of CSU was evaluated using the Urticaria Control Test. RESULTS: Japanese CSU patients showed higher body mass indices, higher intakes of eggs, vegetables other than green/yellow vegetables/mushrooms/algae, cholesterol, folic acid, dietary fibres, vitamin D, vitamin K, Cu, Fe, Pi, Ca, Mg, Na and salt, and lower intake of alcohol, compared to controls. The logistic regression analysis showed that CSU was associated with high body mass index and high intake of eggs. The intake of beverages was higher in uncontrolled CSU patients (Urticaria Control Test â¦11 points) than in controlled patients. The logistic regression analysis showed that uncontrolled CSU was associated with high intake of beverages. The intake of coffee, caffeine-rich and non-alcohol beverage, in uncontrolled CSU patients was higher than that in controlled patients. CONCLUSIONS: Chronic spontaneous urticaria was associated with high body mass index and high intake of eggs. Uncontrolled CSU was associated with high intake of beverages. Further studies should elucidate the relationships of these results with the development or exacerbation of CSU.

Psoriasis is a chronic inflammatory skin disease characterized by accelerated tumor necrosis factor-α/interleukin-23/interleukin-17 axis, hyperproliferation and abnormal differentiation of epidermal keratinocytes. Psoriasis patients are frequently associated with obesity, diabetes, dyslipidemia, cardiovascular diseases, or inflammatory bowel diseases. Psoriasis patients often show unbalanced dietary habits such as higher intake of fat and lower intake of fish or dietary fibers, compared to controls. Such dietary habits might be related to the incidence and severity of psoriasis. Nutrition influences the development and progress of psoriasis and its comorbidities. Saturated fatty acids, simple sugars, red meat, or alcohol exacerbate psoriasis via the activation of nucleotide-binding domain, leucine-rich repeats containing family, pyrin domain-containing-3 inflammasome, tumor necrosis factor-α/interleukin-23/interleukin-17 pathway, reactive oxygen species, prostanoids/leukotrienes, gut dysbiosis or suppression of regulatory T cells, while n-3 polyunsaturated fatty acids, vitamin D, vitamin B12, short chain fatty acids, selenium, genistein, dietary fibers or probiotics ameliorate psoriasis via the suppression of inflammatory pathways above or induction of regulatory T cells. Psoriasis patients are associated with dysbiosis of gut microbiota and the deficiency of vitamin D or selenium. We herein present the update information regarding the stimulatory or regulatory effects of nutrients or food on psoriasis and the possible alleviation of psoriasis by nutritional strategies.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by T helper 2 cell (Th2)-shifted abnormal immunity, skin barrier impairment, and pruritus. The prevalence of AD in childhood is slightly higher in boys than in girls; after puberty, the sexual difference is reversed. The female preponderance in all generations exists in intrinsic AD with enhanced Th1 activity and nickel allergy, lacking increased serum IgE or filaggrin mutation. AD is often deteriorated before menstruation. We review the effects of sex hormones on immune responses and skin permeability barrier and propose possible hypotheses for the above phenomena. After puberty, the immune responses of patients are remarkably influenced by sex hormones. Estrogen and progesterone enhance the activities of Th2/regulatory T cell (Treg) but suppress Th1/Th17. Androgens suppress Th1/Th2/Th17 and induce Treg. The skin permeability barrier is fortified by estrogen but is impaired by progesterone and androgens. Dehydroepiandrosterone suppresses Th2 but enhances Th1. The amount of steroid sulfatase converting dehydroepiandrosterone sulfate to dehydroepiandrosterone is higher in women than in men, and thus, women might be more susceptible to the influence of dehydroepiandrosterone. The balance of modulatory effects of sex hormones on immune responses and skin barrier might regulate the course of AD.

Psoriasis, a chronic inflammatory dermatosis, is frequently associated with metabolic disorders, suggesting that adipokines are involved in its pathogenesis. We recently reported that the adipokine visfatin activates NF-κB and STAT3 in keratinocytes. Antimicrobial peptide expression is enhanced in psoriatic lesions and may promote disease development. Here, we investigated the effects of visfatin on antimicrobial peptide expression. In vitro, visfatin enhanced basal and tumor necrosis factor-α (TNF-α)-induced mRNA expression and secretion of cathelicidin antimicrobial peptide (CAMP), and enhanced TNF-α-induced human ß-defensin-2 (hBD-2), hBD-3, and S100A7 mRNA expression and secretion in human keratinocytes. siRNAs targeting CCAAT/enhancer-binding protein-α (C/EBPα) suppressed visfatin-induced and visfatin plus TNF-α-induced CAMP production. siRNAs targeting NF-κB p65 and STAT3 suppressed visfatin plus TNF-α-induced hBD-2 and S100A7 production. siRNAs targeting c-Jun and STAT3 suppressed visfatin plus TNF-α-induced hBD-3 production. Visfatin and/or TNF-α enhanced C/EBP transcriptional activity and C/EBPα phosphorylation, which were suppressed by p38 mitogen-activated protein kinase (MAPK) inhibition. Visfatin and/or TNF-α induced p38 MAPK phosphorylation. Visfatin increased mRNA and protein expression of CAMP, hBD-2, hBD-3, and S100A7 orthologs in murine imiquimod-treated skin, mimicking psoriasis. In conclusion, visfatin enhances CAMP, hBD-2, hBD-3, and S100A7 production in human keratinocytes and their orthologs in murine imiquimod-treated psoriatic skin. Visfatin may potentiate the development of psoriasis via antimicrobial peptides.

Bimekizumab, which suppresses both interleukin (IL)-17A and IL-17F, has recently been approved as a biologic for psoriasis. We aimed to evaluate the real-world effectiveness and safety of bimekizumab for psoriasis and to identify predictive factors for its treatment responsiveness. We analyzed 36 Japanese patients with psoriasis (19 with psoriasis vulgaris and 17 with psoriatic arthritis) from May 2022 to September 2023. All patients received bimekizumab (320 mg every 4 weeks) until week 16. Seventeen patients (43.2%) had experienced bio-switch. The median (interquartile range) baseline total psoriasis area and severity index (PASI) was 6 (3.2-20.0). Total PASI rapidly and significantly decreased at week 4 by a median 79.8% from baseline, and gradually decreased thereafter. The PASI on the trunk, and upper and lower limbs rapidly and significantly decreased at week 4 compared to baseline and plateaued thereafter. The neutrophil-to-lymphocyte ratio and neutrophil number significantly decreased at week 16 compared to baseline. At weeks 4, 8, 12, and 16, the achievement rate of absolute PASI ≤2 was 72.2%, 80.6%, 92.9%, and 96.4%, respectively; that of absolute PASI ≤1 was 41.7%, 61.3%, 85.7%, and 82.1%; that of PASI 75 was 55.5%, 52.9%, 69.7%, and 75.8%; that of PASI 90 was 36.1%, 50.0%, 57.6%, and 62.9%; and that of PASI 100 was 19.4%, 38.2%, 51.5%, or 57.6%, respectively. Linear multivariate regression analysis revealed that younger age was associated with a higher percentage reduction of total PASI at weeks 4 and 8. There were no serious or fatal adverse events during treatment. In conclusion, bimekizumab rapidly and remarkably reduced the total PASI together with high achievement rates of absolute PASI ≤1 and ≤2, and with favorable safety in real-world clinical practice. Younger age may be a predictive factor for a good treatment response to bimekizumab.

BACKGROUND: Previous clinical trials presented efficacy and safety of Janus kinase 1 inhibitor upadacitinib through 52 weeks for moderate-to-severe atopic dermatitis (AD). OBJECTIVES: To assess the effectiveness and safety of upadacitinib through 48 weeks in real-world clinical practice for Japanese AD patients (aged ≥12 years). METHODS: This retrospective study included 287 patients with moderate-to severe AD treated with 15 mg (n = 216) or 30 mg (n = 71) of upadacitinib daily. Effectiveness was assessed using eczema area severity index (EASI) scores, atopic dermatitis control tool (ADCT), peak pruritus-numerical rating scale (PP-NRS), and investigator's global assessment (IGA). Safety was evaluated through the incidence of treatment-emergent adverse events. RESULTS: From baseline, EASI, ADCT, PP-NRS, and IGA rapidly reduced at week 4, and the reduction was maintained until week 48 of treatment with upadacitinib at both doses. Achievement rates of EASI 75, EASI 90, and EASI 100 at week 48 were 63.5, 30.2, and 7.9 in 15 mg group, and 77.4, 54.8, and 3.2% in 30 mg group, respectively. Acne and herpes zoster were frequent, but no serious adverse events occurred. CONCLUSIONS: Upadacitinib was therapeutically effective and tolerable for moderate-to-severe AD through 48 weeks in real-world clinical practice.

BACKGROUND: Deucravacitinib is a selective oral tyrosine kinase 2 (TYK2) inhibitor recently approved for psoriasis. OBJECTIVES: We aimed to evaluate the real-world effectiveness and safety of deucravacitinib for psoriasis. METHODS: We analyzed 33 Japanese patients with psoriasis (23 with plaque psoriasis, eight with psoriatic arthritis, and two with erythrodermic psoriasis) from January 2023 to October 2023. All patients received deucravacitinib 6 mg daily until week 16. RESULTS: At week 8, 12, or 16, the achievement rate of PASI 75 was 60.9%, 73.9%, or 78.3%, that of PASI 90 was 13.0%, 39.1%, or 52.2%, that of PASI 100 was 0%, 8.7%, or 13.0%, that of absolute PASI ≤2 was 34.8%, 65.2%, or 78.3%, respectively. The achievement rate of dermatology life quality index 0/1 at week 16 was 42.9%. Fourteen patients (42%) complained pruritus. Peak pruritus-numerical rating scale in patients with pruritus decreased by median [interquartile] 71.4 [50-80] % of baseline at week 2. Adverse events occurred in 18.2% of patients, which were mild and manageable. CONCLUSIONS: Deucravacitinib for patients with psoriasis was well-tolerated and gave favorable therapeutic effects in the real-world practice. Deucravacitinib treatment rapidly reduced pruritus.

BACKGROUND: Atopic dermatitis is characterized by persistent eczema and pruritus. Janus kinase inhibitors, including upadacitinib, are effective treatments for moderate-to-severe atopic dermatitis. If patients do not respond well to a certain dose of a Janus kinase inhibitor, increasing the dose may improve their treatment responsiveness. OBJECTIVES: We assessed the outcomes of a dose increase in upadacitinib from 15 mg to 30 mg for Japanese patients with moderate-to-severe atopic dermatitis. METHODS: In 23 patients who showed insufficient responses to upadacitinib 15-mg treatment, the dose of upadacitinib was increased to 30 mg. We evaluated total Eczema Area and Severity Index (EASI), EASI on the head and neck, trunk, upper, or lower limbs, EASI of erythema, edema/papulation, excoriation, or lichenification, and Peak Pruritus Numerical-Rating Scale at baseline (onset of upadactinib 15 mg), week 0 (time of increase), and weeks 4 and 12 after the increase. RESULTS: Total EASI, EASI on each anatomical site, EASI of each clinical sign, and Peak Pruritus Numerical-Rating Scale were markedly reduced at weeks 4 or 12 compared with week 0. After the dose increase, the achievement rates of EASI 75 and EASI 90 significantly improved; EASI 75 4.3%, 68.2%, and 66.7%; EASI 90 0%, 18.2%, and 38.1% at weeks 0, 4, and 12, respectively. CONCLUSIONS: These results suggest that upadacitinib 30 mg can ameliorate rash and pruritus insufficiently improved by upadacitinib 15 mg, and that the dose increase to 30 mg may be considered as a treatment option for patients with atopic dermatitis with a limited response to upadacitinib 15 mg.

Clinical trials and real-world studies have shown the effectiveness of upadacitinib for treating rash and pruritus in patients with atopic dermatitis (AD). This study aimed to determine whether the early reduction in rash or pruritus at week 12 of upadacitinib treatment could be maintained at later treatment stages. This retrospective study involved 227 and 73 patients with moderate-to-severe AD treated with 15 and 30 mg upadacitinib daily, respectively. The eczema area and severity index (EASI) scores, peak pruritus numerical rating scale (PP-NRS), and investigator's global assessment (IGA) were analyzed. At week 12, patients were divided into achievers and non-achievers of EASI 75, 90, 100, absolute EASI ≤ 2, IGA0/1, PP-NRS4, or absolute PP-NRS ≤ 1. Achievement rates for each endpoint were assessed at later time points (weeks 24, 36, and 48) in both groups. Week 12 achievers largely maintained their endpoint achievements until week 48, regardless of dosage (15 mg or 30 mg). Week 12 non-achievers saw an increasing achievement rate of EASI 75 until week 48. The initial reduction in rash and pruritus at week 12 persisted until week 48 with upadacitinib treatment, suggesting potential benefits for patients requiring prolonged treatment despite not achieving EASI 75 at week 12.
RESUMO
Background: Atopic dermatitis (AD) is a chronic skin disease characterized by type 2-skewed immune responses, and significantly influenced by cytokines dependent on Janus kinases (JAKs). Upadacitinib, a JAK1 inhibitor, is effective for moderate-to-severe AD. This study aims to identify biomarkers that reflect long-term therapeutic effects of upadacitinib 15 mg or 30 mg. Methods: A retrospective study from August 2021 to July 2023 included 213 AD patients treated with upadacitinib 15 mg and 70 AD patients with 30 mg. We analyzed eczema area and severity index (EASI), peak pruritus-numerical rating scale (PP-NRS), serum immunoglobulin E (IgE), thymus and activation-regulated chemokine (TARC), lactate dehydrogenase (LDH), and total eosinophil count (TEC) at weeks 0, 4, 12, 24, 36, and 48 of treatment. Results: Both treatments with upadacitinib 15 mg and 30 mg significantly reduced EASI and PP-NRS scores over week 4 to 48 compared to baseline. Upadacitinib 15 mg or 30 mg treatment significantly decreased TEC compared to baseline through week 4 to 36 or week 4 to 48, respectively. The percent reduction of TEC correlated with those of EASI and PP-NRS through week 4 to 48 of treatment with upadacitinib 15 mg, or through week 12 to 48 with 30 mg, respectively. After adjusting for % reductions of other laboratory markers, the significance of correlations was preserved at weeks 36 and 48 of 15 mg treatment, while at weeks 4 and 36 of 30 mg treatment. Conclusion: The % reduction of TEC correlated with those of EASI and PP-NRS during upadacitinib treatment, indicating its potential as a biomarker reflecting treatment responses to upadacitinib in AD patients. However, the variability of significant correlation during treatment indicates that further inspection is needed for its usefulness in monitoring responses to upadacitinib treatment for AD.

Psoriasis is a complex, chronic inflammatory skin disease that significantly impacts patients' quality of life (QOL), especially in cases of genital, nail, and scalp psoriasis. Bimekizumab is an inhibitor of interleukin (IL)-17A and IL-17F and used for the treatment of psoriasis. The aim of this retrospective study was to evaluate the effectiveness of bimekizumab through in treating genital, nail, and scalp lesions with psoriasis over 24 weeks. The study was conducted from May 2022 and February 2024 on 52 psoriasis patients treated with bimekizumab. The therapeutic effects of bimekizumab were evaluated by the achievement of Physician's Global Assessment (PGA) rates of 0/1 on the genitals (genital-PGA), fingernails (PGA-F), scalp-specific PGA (ss-PGA), static PGA (sPGA), and the Dermatology Life Quality Index (DLQI) at weeks 4, 16, and 24. Bimekizumab treatment significantly improved genital, nail, and scalp lesions with psoriasis. At week 24, the achievement rate of genital-PGA 0/1, PGA-F 0/1, ss-PGA 0/1 was 96.2%, 66.7%, or 93.9%, and that of sPGA 0/1 or DLQI 0/1 was 93.9% or 83.3%, respectively. Bimekizumab was effective for genital, nail, and scalp lesions with psoriasis, difficult-to-treat lesions, and simultaneously improved QOL in a real-world clinical practice.
RESUMO
BACKGROUND: Janus kinase 1 inhibitor upadacitinib is therapeutically effective for atopic dermatitis (AD). However, predictive factors for high responders to upadacitinib have not been established in real-world clinical practice. OBJECTIVES: To identify predictive factors for responders to upadacitinib 15 mg or 30 mg, defined as achievers of investigator's global assessment (IGA) 0/1 with ≥ 2-point improvement from basal IGA. METHODS: A retrospective study was conducted from August 2021 to July 2023 on 159 AD patients treated with upadacitinib 15 mg and 52 patients with 30 mg. Patients in each group were categorized into responders (achievers of IGA 0/1 at week 12) and non-responders (non-achievers). We compared baseline values of clinical and laboratory parameters between responders and non-responders. Logistic regression analysis was used to detect variables predicting responders. Receiver-operating characteristic curves were used for evaluating prediction capabilities of the variables. RESULTS: In logistic regression analysis, responders to 15 mg upadacitinib were associated with lower total EASI and higher age whereas responders to 30 mg were associated with lower LDH and lower IgE. CONCLUSIONS: Lower total EASI and higher age may predict responders to upadacitinib 15 mg while lower IgE and lower LDH may predict responders to 30 mg.
