Feasibility and Diagnostic Value of Recording Smartwatch Electrocardiograms in Neonates and Children.

OBJECTIVE: The objective of this study was to evaluate the agreement of smartwatch-derived single-lead electrocardiogram (ECG) recordings with 12-lead ECGs for diagnosing electrocardiographic abnormalities. STUDY DESIGN: A 12-lead ECG and an ECG using Apple Watch were obtained in 110 children (aged 1 week to 16 years) with normal (n = 75) or abnormal (n = 35) 12-lead ECGs (atrioventricular block [7], supraventricular tachycardia [SVT] {5}, bundle branch block [12], ventricular preexcitation [6], long QT [5]). In children aged <6 years, the ECG recording was performed with the active participation of an adult who applied the neonate or child's finger to the crown of the watch. In older children, tracings were obtained after brief teaching without adult guidance. All 12-lead ECGs were independently evaluated by 2 blinded cardiologists. Apple Watch ECGs were independently evaluated by another blinded cardiologist. RESULTS: In 109 children (99.1%), the smartwatch tracing was of sufficient quality for evaluation. Smartwatch tracings were 84% sensitive and 100% specific for the detection of an abnormal ECG. All 75 normal tracings were correctly identified. Of the 35 children with abnormalities on 12-lead ECGs, 5 (14%) were missed, most often because of baseline wander and artifacts. Rhythm disorders (atrioventricular block or SVT) and bundle branch blocks were correctly detected in most cases (11 of 12 and 11 of 12, respectively); preexcitation and long QT was detected in 4 of 6 and 4 of 5, respectively. CONCLUSION: Smartwatch ECGs recorded with parental assistance in children aged up to 6 years and independently in older children have the potential to detect clinically relevant conditions.

Defining the physician global assessment threshold equivalent to remission in patients with systemic lupus erythematosus.

OBJECTIVES: The optimal threshold of the physician global assessment (PGA) for remission in SLE has never been evaluated systematically. The aim of this study was to assess the ideal PGA threshold associated with physician remission and to investigate its impact on remission rates in our Lupus cohort. METHODS: In this monocentric cross-sectional study, patients with SLE were evaluated for physician remission by asking the treating physicians if they considered their patient in remission regardless of objective remission criteria. Further, two objective remission definitions were applied: 1) DORIS remission using a PGA of < 2 (0-10) (corresponding to < 0.5 on a VAS 0-3 used in DORIS); 2) DORIS remission with omission of PGA (modDORIS). A receiver operating characteristic analysis and regression analyses were performed to assess the ideal PGA threshold and factors influencing PGA. RESULTS: Of the 233 patients included, 126 patients (54.0%) were in physician remission, 42.5% in DORIS remission and 67.0% in modDORIS remission. A PGA of < 2 NRS 0-10) had the highest sensitivity (79%) and specificity (81%) for physician remission and modDORIS (AUC 0.85 and 0.69). PGA of patients fulfilling any of the remission definitions was associated with pain and hypocomplementemia. Damage was numerically higher in patients in modDORIS only; no association between PGA and damage was found in regression analysis. CONCLUSION: Using a PGA threshold of < 2 (0-10), corresponding to < 0.6 (0-3) resulted in best prediction of physician remission. PGA levels seem to be influenced by pain and complement levels but not disease damage.

Paediatric rheumatologists do not score the physician's global assessment of juvenile idiopathic arthritis disease activity in the same way.

OBJECTIVES: To assess the heterogeneity in factors affecting physician's global assessment of disease activity (PhGA) and in PhGA scoring of multiple JIA patient's case scenarios. METHODS: An electronic web-based questionnaire of factors potentially considered in PhGA was sent worldwide to members of PRINTO and the Pediatric Rheumatology Care and Outcomes Improvement Network (PR-COIN). The respondents were asked to rate from 0 to 100 the relevance of 17 factors possibly affecting PhGA scoring and to derive a PhGA score of 17 detailed JIA patient cases. The median and interquartile range was used to measure the heterogeneity in the scoring. To demonstrate the consistency among the PhGA scores of the patient cases provided by multiple physicians, we assessed the inter-rater reliability using intra-class correlation. RESULTS: The questionnaire was completed by 491 respondents. A large individual variation was observed in the impact of different factors on PhGA when assessing JIA. For non-systemic JIA the presence of fever had the largest variation and swollen joint count had the smallest. For sJIA, the largest variation was seen in the presence of erosions and the smallest in the presence of fever. The intra-class correlation of the group for PhGA scoring of patient cases was 0.53 (95% CI 0.38, 0.72). CONCLUSIONS: In a sample of worldwide respondents, the scoring of the PhGA is divergent. Consensus on PhGA scoring guidelines is required to obtain a consistent assessment of patients.

Oral spleen tyrosine kinase/Janus Kinase inhibitor gusacitinib for the treatment of chronic hand eczema: Results of a randomized phase 2 study.

BACKGROUND: Gusacitinib is an oral inhibitor of Janus and Spleen tyrosine kinases. METHODS: The efficacy and safety of gusacitinib were evaluated in a double-blind, placebo-controlled, multicenter, phase 2 study in 97 chronic hand eczema patients randomized (1:1:1) to placebo or gusacitinib (40 or 80 mg) for 12 weeks (part A). Then, in part B (through week 32), the patients received gusacitinib. RESULTS: At week 16, patients receiving 80 mg gusacitinib showed a 69.5% (P <.005) decrease in the modified total lesion-symptom score versus 49.0% for 40 mg (P =.132), and 33.5% for placebo. Considerable improvement in Physician's Global Assessment was seen in 31.3% of patients receiving 80 mg versus 6.3% of placebo (P <.05). A 73.3% decrease in the hand eczema severity index versus placebo (21.7%) occurred in patients receiving 80 mg (P <.001). Patients receiving 80 mg experienced a considerable decrease in hand pain (P <.05). As early as week 2, considerable reductions over placebo in modified total lesion-symptom score (P <.005), Physician's Global Assessment (P =.04), and hand eczema severity index (P <.01) were observed (80 mg gusacitinib). Adverse events included upper respiratory infection, headache, nausea, and nasopharyngitis. CONCLUSIONS: Gusacitinib showed rapid improvement in chronic hand eczema patients and was well tolerated, warranting further investigations.

Deucravacitinib versus placebo and apremilast in moderate to severe plaque psoriasis: Efficacy and safety results from the 52-week, randomized, double-blinded, placebo-controlled phase 3 POETYK PSO-1 trial.

BACKGROUND: Effective, well-tolerated oral psoriasis treatments are needed. OBJECTIVE: To compare the efficacy and safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, versus placebo and apremilast in adults with moderate to severe plaque psoriasis. METHODS: Participants were randomized 2:1:1 to deucravacitinib 6 mg every day (n = 332), placebo (n = 166), or apremilast 30 mg twice a day (n = 168) in the 52-week, double-blinded, phase 3 POETYK PSO-1 trial (NCT03624127). Coprimary end points included response rates for ≥75% reduction from baseline in Psoriasis Area and Severity Index (PASI 75) and static Physician's Global Assessment score of 0 or 1 (sPGA 0/1) with deucravacitinib versus placebo at week 16. RESULTS: At week 16, response rates were significantly higher with deucravacitinib versus placebo or apremilast for PASI 75 (194 [58.4%] vs 21 [12.7%] vs 59 [35.1%]; P < .0001) and sPGA 0/1 (178 [53.6%] vs 12 [7.2%] vs 54 [32.1%]; P < .0001). Efficacy improved beyond week 16 and was maintained through week 52. Adverse event rates with deucravacitinib were similar to those with placebo and apremilast. LIMITATIONS: One-year duration, limited racial diversity. CONCLUSION: Deucravacitinib was superior to placebo and apremilast across multiple efficacy end points and was well tolerated in moderate to severe plaque psoriasis.

Deucravacitinib versus placebo and apremilast in moderate to severe plaque psoriasis: Efficacy and safety results from the 52-week, randomized, double-blinded, phase 3 Program fOr Evaluation of TYK2 inhibitor psoriasis second trial.

BACKGROUND: Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, inhibits cytokine signaling in psoriasis pathogenesis. OBJECTIVE: The objective of this study was to demonstrate deucravacitinib superiority versus placebo and apremilast in moderate to severe plaque psoriasis based on ≥75% reduction from baseline in Psoriasis Area and Severity Index and a static Physician's Global Assessment score of 0 (clear) or 1 (almost clear) with a ≥2-point improvement from baseline at week 16. METHODS: POETYK psoriasis second trial (NCT03611751), a 52-week, double-blinded, phase 3 trial, randomized patients 2:1:1 to deucravacitinib 6 mg every day (n = 511), placebo (n = 255), or apremilast 30 mg twice a day (n = 254). RESULTS: At week 16, significantly more deucravacitinib-treated patients versus placebo and apremilast patients achieved ≥75% reduction from baseline in Psoriasis Area and Severity Index (53.0% vs 9.4% and 39.8%; P < .0001 vs placebo; P = .0004 vs apremilast) and static Physician's Global Assessment score of 0 or 1 (49.5% vs 8.6% and 33.9%; P < .0001 for both). Efficacy was maintained until week 52 with continuous deucravacitinib. The most frequent adverse event with deucravacitinib was nasopharyngitis. Serious adverse events and discontinuations due to adverse events were infrequent. No clinically meaningful changes were observed in laboratory parameters. LIMITATIONS: The study duration was 1 year. CONCLUSION: Deucravacitinib demonstrated superiority versus placebo and apremilast and was well tolerated in adults with moderate to severe plaque psoriasis.

Patient-reported outcomes in ANCA-associated vasculitis: a cross-sectional study to explore the interactions between patients' and physicians' perspectives.

To evaluate associations between the domains of the ANCA-associated vasculitis patient-reported outcome (AAV-PRO) instrument and clinical variables. Patients with granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), or renal-limited vasculitis (RLV) were recruited from a tertiary care center in Mexico City. Demographic, clinical, serological, and treatment-related data were retrieved. Disease activity, damage, patient and physician global assessments (PtGA and PhGA) were evaluated. All patients completed the AAV-PRO questionnaire, male patients also completed the International Index of Erectile Function (IIEF-5) questionnaire. Seventy patients (44 women and 26 men) were included, with a median age of 53.5 years (43-61), and a disease duration of 82 months (34-135). Moderate correlations were identified between the PtGA and the AAV-PRO domains: social and emotional impact, treatment side effects, organ-specific symptoms, and physical function. The PhGA correlated with the PtGA and prednisone doses. Subanalyses of the AAV-PRO domains according to sex, age, and disease duration showed significant differences in the treatment side effects domain, with higher scores in women, in patients < 50 years, and in patients with disease duration < 5 years. The domain of concerns about the future showed a higher score in patients with disease duration < 5 years. A total of 17/24 (70.8%) of men who completed the IIEF-5 questionnaire were classified as having some degree of erectile dysfunction. The domains of AAV-PRO correlated with other outcome measures, while differences were found between some of the domains according to sex, age, and disease duration.

Choice of and response to treatment in patients with early-diagnosed rheumatoid arthritis: Real-world data from an inception cohort in Japan (NICER-J).

OBJECTIVE: Various guidelines recommend that patients with early rheumatoid arthritis (RA) try to achieve clinical remission within 6 months, and early therapeutic intervention is important to this end. This study aimed to investigate short-term treatment outcomes of patients with early-diagnosed RA in clinical practice and to examine predictive factors for achieving remission. METHODS: Of the 210 patients enrolled in the multicenter RA inception cohort, 172 patients who were followed up to 6 months after treatment initiation (baseline) were included. Logistic regression analysis was used to examine the impact of baseline characteristics on achievement of Boolean remission at 6 months. RESULTS: Participants (mean age, 62 years) initiated treatment after a mean of 19 days from RA diagnosis. At baseline and 3 and 6 months after treatment initiation, proportions of patients using methotrexate (MTX) were 87.8%, 89.0%, and 88.3%, respectively, and rates of Boolean remission were 1.8%, 27.8%, and 34.5%, respectively. Multivariate analysis revealed that physician global assessment (PhGA) (Odds ratio (OR): 0.84, 95% confidence interval (CI): 0.71-0.99) and glucocorticoid use (OR: 0.26, 95% CI: 0.10-0.65) at baseline were independent factors that predicted Boolean remission at 6 months. CONCLUSION: After a diagnosis of RA, satisfactory therapeutic effects were achieved at 6 months after the initiation of treatment centered on MTX according to the treat to target strategy. PhGA and glucocorticoid use at treatment initiation are useful for predicting the achievement of treatment goals.

Validation of the Physician's Global Assessment of Fingernail Psoriasis by Rheumatologists Treating Psoriatic Arthritis.

OBJECTIVES: This study aimed to assess the content validity and reliability of the Physician's Global Assessment of Fingernail Psoriasis (PGA-F) by rheumatologists treating patients with psoriatic arthritis. METHODS: There were 3 stages of analyses with 3 clinician cohort groups. Stage 1 (concept confirmation) included rheumatologist qualitative data (cohort 1) to establish content validity, acceptability, utility, and feasibility of the PGA-F in assessing nail severity. Quantitative information regarding the response category utilization in nail abnormalities was assessed by photographs. Stage 2 (inter-rater reliability) involved quantitative analysis of PGA-F data from study investigators, including rheumatologists, involved in a phase III clinical study (cohort 2) and a cohort of newly recruited rheumatologists (cohort 3). Stage 3 included known-groups validity. RESULTS: Qualitative analyses identified consensus that the PGA-F severity levels are comprehensive of real-world patient symptoms and the instrument is simple to use and understand. Psychometric analyses support the PGA-F as a clinical outcome assessment tool. Inter-rater reliability showed rheumatologist agreement across the fingernail psoriasis severity spectrum. They were monotonically ordered by the hypothesized severity structure with excellent fit to the clinicians who evaluated them. Agreement on the rank order of the severity of the photographs in this target rheumatologist population was consistent with previous reports by dermatologists. CONCLUSIONS: The PGA-F was shown to be usable by rheumatologists to measure patients along the full range of the fingernail psoriasis severity spectrum, have a strong relationship with a conceptually similar reference measure, differentiate among patients based on fingernail psoriasis severity, and detect category severity change over a 24-week period.

Reliability Assessment and Validation of the Skin Hyperpigmentation Index Compared to the Physician Global Assessment Score.

BACKGROUND: The skin hyperpigmentation index (SHI), a new objective method for measuring skin hyperpigmentation, needs validation. OBJECTIVE: To gain evidence of the reliability and validity of the SHI. METHODS: Fifteen raters were divided into 3 groups (5 dermatologists, 5 nondermatologist physicians, and 5 nonphysician clinicians). Each rated 5 pigmented mole lesions with mild-to-severe hyperpigmentation to determine intra- and interrater reliability. All raters photographed the lesions and rated them using the subjective Physician Global Assessment (PGA) score. The same photographs were then assessed based on automatic computer measurement software using the online SHI tool (https://shi.skinimageanalysis.com). RESULTS: The SHI reliability was excellent for all intra- and interrater assessments, while most PGA assessments showed good intra- and interrater agreement. Between-group reliability was excellent for SHI, while moderate-to-good for PGA evaluations. Concordance between the SHI and PGA assessments was strong across all groups of assessors. CONCLUSION: There is evidence that the SHI is a reliable instrument for measuring skin hyperpigmentation, and can be used by nonexperienced clinicians.

Whole-body MRI at initial presentation of pediatric chronic recurrent multifocal osteomyelitis and correlation with clinical assessment.

BACKGROUND: Chronic recurrent multifocal osteomyelitis (CRMO) is a diagnosis of exclusion, relying heavily on whole-body magnetic resonance imaging (WB-MRI) for diagnosing and evaluating response to therapy. Information with respect to disease distribution and imaging correlation with clinical disease severity at initial presentation is lacking. OBJECTIVE: To retrospectively characterize distribution of disease on WB-MRI and to correlate imaging findings with disease severity at initial rheumatology presentation. MATERIALS AND METHODS: Using a modified version of a recently devised imaging-based scoring system, we evaluated disease distribution and correlation between findings on WB-MRI and clinical disease severity in 54 patients presenting for initial evaluation of CRMO. Symptomatic lesion sites were extracted from chart review and physician global assessment was determined by the consensus of two rheumatologists. RESULTS: Sites of CRMO involvement evident on imaging at initial presentation had a strong predilection for the pelvis and lower extremities. There was significant correlation between the number of lesions detected on WB-MRI and total clinical severity score at initial rheumatology presentation (P<0.01). However, no other imaging parameter correlated with disease severity. CONCLUSION: While the overall number of lesions identified on MRI correlates with clinical severity scores at initial imaging, other MR parameters of CRMO lesions may not be reliable indicators of disease severity at initial presentation. Further research is needed to assess whether these parameters are implicated in longitudinal disease severity or overall response to therapy.

Associations between physicians' global assessment of disease activity and patient-reported outcomes in patients with systemic lupus erythematosus: A longitudinal study.

OBJECTIVE: To determine longitudinal associations between Physician Global Assessment (PGA) and patient-reported outcomes (PROs) in patients with systemic lupus erythematosus (SLE). METHODS: Patients attending a rheumatology clinic between 2013 and 2017 completed specific (SLEQOL) and generic (SF36) health-related quality of life (HRQoL) surveys and rated their global rating of change (GRC) at each visit. PGA, SLEDAI-2K and SLE Flare Index (SFI) were also captured on all visits. Generalised estimating equations (GEE) methods were used to examine longitudinal associations of PGA with PROs and clinical indicators. RESULTS: 337 patients were followed for a median [IQR] of 3.2 [1.6, 3.4] years (2,059 visits). High PGA (>1) was strongly associated with high SLEDAI-2K scores, the presence of flares and poor PROs. Odd ratios (OR) [95% CI] of PGA > 1 in patients with SLEDAI-2K >4 & <10 and SLEDAI-2K ≥10, compared to SLEDAI-2K ≤ 4, were 3.46 [2.36, 5.08], p < 0.001 and 6.39 [4.30, 9.49], p < 0.001, respectively. OR [95% CI] of PGA > 1 in patients with mild-to-moderate or severe flares were 2.09 [1.62, 2.71], p < 0.001 and 4.42 [3.21, 6.07], p < 0.001, respectively. Mental components of both SLEQOL (mood, self-image) and SF36 (MCS) surveys demonstrated significant associations with high PGA. After adjusting for SLEDAI-2K, one-point increase in PGA was associated with reductions in SLEQOL total score and SF36-MCS by 2.33 (regression coefficient (RC) [95% CI] = -2.33 [-3.77, -0.88], p = 0.002), and 4.16 (RC [95% CI] = -4.16 [-5.19, -3.13], p < 0.001) points, respectively. Associations of some physical components (SLEQOL-symptoms, and SF36-PCS) with PGA attenuated when adjusted for SLEDAI-2K. Patients who rated low scores of GRC, which indicate health deterioration, were twice as likely to have PGA > 1 (OR [95%CI] 1.99 [1.25, 3.16], p = 0.004). CONCLUSION: High PGA was strongly associated with poor mental health, high disease activity and flares. This study confirms the value of PGA as an efficient assessment tool for SLE.

Morphea patients with mucocutaneous involvement: A cross-sectional study from the Morphea in Adults and Children (MAC) cohort.

BACKGROUND: Demographic and clinical findings of patients with mucocutaneous morphea have not been well characterized, to our knowledge. OBJECTIVE: To determine the demographic and clinical characteristics of morphea patients with mucocutaneous lesions who were enrolled in the Morphea in Adults and Children cohort. METHODS: Cross-sectional study of 735 patients in the Morphea in Adults and Children cohort from 2007 to 2018. RESULTS: A total of 4.6% of linear morphea patients had oral involvement versus 2.4% among the entire cohort, whereas 10.3% of generalized morphea patients had genital involvement versus 3.7% among the entire cohort. Patients with genital lesions were older at disease onset than those with oral morphea (57 versus 11.5 years; P < .001) and had more frequent extragenital lichen sclerosus et atrophicus (59.2% versus 5.6%; P = .004). LIMITATIONS: Selection bias and limited number of affected subjects. CONCLUSION: Oral morphea lesions predominate in younger patients with facial linear morphea, whereas genital lesions predominate in postmenopausal women with overlying extragenital lichen sclerosus et atrophicus.

Evaluation of the fragility of pivotal trials used to support US Food and Drug Administration approval for plaque psoriasis.

BACKGROUND: Over the last 5 years, there has been a rapid growth in the number of clinical trials used to support a US Food and Drug Administration (FDA) approval for systemic therapies with labeled indications for plaque psoriasis. OBJECTIVE: We aim to evaluate the fragility of clinical trial data used to support FDA approval of therapies for psoriasis. METHODS: We reviewed the primary endpoints of the pivotal trials of all systemic medications with a labeled indication for plaque psoriasis available from Drugs@FDA. RESULTS: Sixty-nine clinical trial primary endpoints met inclusion criteria and were assessed for robustness, yielding a median fragility index of 72 and a median fragility quotient of 0.19. LIMITATIONS: Efficacy and statistical analysis data for several approved medications were not available on the product label or on Drugs@FDA. CONCLUSIONS: When compared with randomized controlled trials for FDA approval across various diseases, pivotal trials in psoriasis appear quite robust to changes in outcomes.

Use of Physician Global Assessment in systemic lupus erythematosus: a systematic review of its psychometric properties.

OBJECTIVE: The Physician Global Assessment (PGA) is a visual analogue score that reflects the clinician's judgement of overall SLE disease activity. The aim of this systematic literature review is to describe and analyse the psychometric properties of the PGA. METHODS: This systematic literature review was conducted by two independent reviewers in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. All articles published through 1 July 2019 in PubMed were screened, with no limitation on year of publication, language or patients' age. Psychometric properties data were analysed according to the OMERACT Filter methodology version 2.1. RESULTS: The literature search identified 91 studies. Face validity was reported in all the articles retrieved in which the PGA was used alone or as part of composite indices (Systemic Responder Index, Safety of Estrogen in Lupus Erythematosus National Assessment Flare Index, Lupus Low Disease Activity State, Definitions of Remission in Systemic Lupus Erythematosus criteria). Content validity was reported in 89 studies. Construct validity was demonstrated by a good correlation (r ≥ 0.50) between the PGA with the SLEDAI (12 studies), SLAM (4 studies), LAI, BILAG and ECLAM (2 studies each). Criterion validity was assessed exploring the PGA correlation with quality of life measurements, biomarker levels and treatment changes in 28 studies, while no study has evaluated correlation with damage. A good responsiveness for PGA was shown in eight studies. A high variability in scales was found, causing a wide range of reliability (intraclass correlation coefficient 0.67-0.98). CONCLUSION: PGA is a valid, responsive and feasible instrument, though its reliability was impacted by the scale adopted, suggesting the major need for standardization of its scoring.

PGAxBSA composite versus PASI: Comparison across disease severities and as therapeutic response measure for Cal/BD foam in plaque psoriasis.

BACKGROUND: The product of the Physician Global Assessment and body surface area (PGA×BSA) is simpler to use than the Psoriasis Area and Severity Index (PASI), which lacks sensitivity in patients with mild psoriasis. OBJECTIVE: To compare the PGA×BSA versus the modified PASI (mPASI) for assessing disease severity and therapeutic response to calcipotriol/betamethasone dipropionate (Cal/BD) foam. METHODS: This post hoc analysis evaluated the efficacy of Cal/BD foam in mild, moderate, and severe psoriasis, as assessed by the PGA×BSA and mPASI, using data from 3 randomized controlled trials (NCT01536886, NCT01866163, NCT02132936). Spearman correlation and Bland-Altman plots were used to compare the PGA×BSA with the mPASI. RESULTS: Proportions of patients receiving Cal/BD foam achieving 75% response for PGA×BSA and mPASI at weeks 1, 2, and 4 were similar and significantly greater than with vehicle (P ≤ .002 at all timepoints); at week 4, mean improvements were 51.0% and 50.7%, respectively. Spearman correlations for mild, moderate, and severe psoriasis were moderate to high between PGA×BSA and mPASI at baseline (r = .51, .72, and .86, respectively; n = 126, 465, and 58, respectively) and high at week 4 (r = .80, .81, and .89, respectively; n = 121, 452, and 58, respectively) (P < .001). LIMITATIONS: Pooled data from different trials were not prespecified for post hoc analysis. Interrater reliability was not assessed. CONCLUSION: Pooled data analysis showed that the PGA×BSA and mPASI correlation was higher with increasing psoriasis severity.

A network meta-analysis for the comparison of efficacy and safety of interleukin (IL)-23 targeted drugs in the treatment of moderate to severe psoriasis.

A variety of interleukin-23 targeted drugs have been used to treat moderate to severe psoriasis, but it is not clear which is most effective. This network meta-analysis compared and summarized the short-term efficacy and safety of interleukin-23 (IL-23) targeted drugs in the treatment of moderate to severe psoriasis. PubMed, Embase, Web of Science, and Cochrane Library were used to search randomized controlled trials (RCTs) about the treatment of moderate to severe psoriasis with ustekinumab (Ust), guselkumab (Gus), tildrakizumab (Til), and risankizumab (Ris). Bayesian Network Meta-analysis (NMA) was used to calculate Psoriasis Area and Severity Index 75%, 90%; Physician Global Assessment score of 0 or 1 (PGA 0/1); Dermatology Life Quality Index of 0 or 1 (DLQI 0/1), and safety (adverse events [AEs]) effect estimates (odds ratio OR) and 95% confidence intervals. Direct, indirect, and network meta-analysis estimates were calculated using a random-effects model. The GRADE method was used to assess the quality of evidence for each pair-wise comparison. In addition, the surface under the cumulative ranking curve (SUCRA) analysis was used to rank the treatment level for each outcome indicator. This network meta-analysis included 14 RCTs with 8402 patients. The results indicate that the curative effect of the IL-23 targeted drugs is better than that of a placebo. Network meta-analysis showed that Ris90 mg and Ris180 mg were significantly more effective than Til (5, 25, 100, and 200 mg), Ust (45 mg, 90 mg, body weight-based administration), Gus 100 mg and Ris (75 and 150 mg). Regarding safety, there is no significant difference in the risk of adverse events between drugs targeting IL-23 and placebo. In addition, according to the ranking of SUCRA, Ris 90 mg has the best efficacy index for PASI 75 and PGA 0/1, with SUCRA values of 97.6% and 97.1%, respectively. Ris 180 mg ranked first in PASI 90 (91.1%), while Ris 75 mg performed best in DLQI 0/1 (73.7%). In this network meta-analysis, risankizumab showed the best curative effect in the short-term treatment of moderate to severe psoriasis, and the risk of adverse events was not significantly different from placebo. However, more research data are needed for further study in the field of cost to evaluate which drug strikes the most favorable balance among efficacy, safety, and cost of access.

Exploration of the Product of the 5-Point Investigator's Global Assessment and Body Surface Area (IGA × BSA) as a Practical Minimal Disease Activity Goal in Patients with Moderate-to-Severe Psoriasis.

BACKGROUND/AIMS: In the treat-to-target era, psoriasis disease activity measures that can be easily performed in routine clinical practice are needed. This retrospective pooled analysis explored cutoff values of the product of the 5-point Investigator's Global Assessment and percentage of affected body surface area (IGA × BSA) correlating with achievement of minimal disease activity (MDA). METHODS: Post hoc analysis of the phase 3 clinical trials ERASURE, FIXTURE, FEATURE, and JUNCTURE was conducted to determine associations between IGA × BSA and 2 MDA definitions (Psoriasis Area and Severity Index [PASI] 90 and Dermatology Life Quality Index [DLQI] 0/1, or PASI score ≤1 or BSA <3%) in patients with moderate-to-severe psoriasis receiving secukinumab 300 mg. For each definition of MDA, a range of possible cutoff values of IGA × BSA was examined at each time point. The optimal cutoff value was determined using Youden index (YI), calculated as (sensitivity + specificity - 1). RESULTS: For MDA defined as PASI 90 and DLQI 0/1, optimal IGA × BSA cutoffs were 2.10 at week 12 (YI, 0.60; sensitivity, 0.78; specificity, 0.82), 1.02 at week 24 (YI, 0.55; sensitivity, 0.73; specificity, 0.82), and 1.00 at week 52 (YI, 0.65; sensitivity, 0.79; specificity, 0.86). For MDA defined as PASI score ≤1 or BSA <3%, optimal IGA × BSA cutoffs were 2.98 at week 12 (YI, 0.91; sensitivity, 0.99; specificity, 0.92), 2.80 at week 24 (YI, 0.94; sensitivity, 0.99; specificity, 0.95), and 3.00 at week 52 (YI, 0.96; sensitivity, 1.00; specificity, 0.96). CONCLUSION: IGA × BSA could be a valid measure highly associated with achievement of MDA.

A multi-item Physician Global Assessment scale to assess psoriasis disease severity: validation based on four phase III tofacitinib studies.

BACKGROUND: Several different Physician Global Assessment (PGA) versions have been used in clinical studies as a co-primary end point to evaluate psoriasis severity. Tofacitinib is an oral Janus kinase inhibitor. We performed an analysis of the PGA using data from studies of tofacitinib in moderate to severe chronic plaque psoriasis. METHODS: Data from 3641 patients with moderate to severe chronic plaque psoriasis, enrolled in one of four phase III tofacitinib studies (OPT Pivotal 1 and 2, OPT Compare and OPT Retreatment), were used to evaluate a three-item PGA scale. RESULTS: Confirmatory Factor Analyses showed that equal weighting of the three items (erythema, induration and scaling) was appropriate. The PGA demonstrated acceptable test-retest reliability (Intraclass Correlation Coefficient, 0.7) and internal consistency (Cronbach's Coefficient Alpha ≥ 0.9 at primary time points). The Clinically Important Difference was estimated as 0.55 (95% confidence interval: 0.546-0.563). Known-group validity was shown by demonstrating that PGA scores could discriminate between different degrees of disease severity. The PGA was significantly correlated with other clinical end points in the studies (Psoriasis Area and Severity Index, r = 0.75-0.79; Dermatology Life Quality Index, r = 0.44-0.57; Patient Global Assessment, r = 0.66-0.72). CONCLUSIONS: Consistent with previous findings from a phase II study, these results indicate that this PGA is a valid, reliable instrument for evaluating disease severity in clinical studies of psoriasis.
