Impact of disease, musculoskeletal symptoms and disease control in the CorEvitas Psoriasis Registry.

BACKGROUND: Early identification, diagnosis and symptom control of psoriatic arthritis (PsA) in patients with psoriasis remain unmet medical needs. OBJECTIVES: To compare the impact of disease and other characteristics between patients with psoriasis who screened positive for PsA using the Psoriasis Epidemiology Screening Tool (PEST) (screen-positive group) and patients who (i) have PsA (PsA group) or (ii) screened negative for PsA (screen-negative group). Also, to determine the proportion of patients at a patient-acceptable symptom state (PASS) in the screen-positive and PsA groups. METHODS: This was a cross-sectional analysis of the CorEvitas Psoriasis Registry. We included a convenience sample of patients with psoriasis from the screen-positive and PsA groups who completed the Psoriatic Arthritis Impact of Disease-12 (PsAID12), and a comparator screen-negative group who did not complete the PsAID12. We report descriptive summaries of demographics, comorbidities, psoriasis characteristics, patient-reported outcome measures and the proportion of patients at PASS (i.e. PsAID12 ≤ 4). RESULTS: The screen-positive, PsA and screen-negative groups included 369, 70 and 4724 patients, respectively. The screen-positive and PsA groups had a similar impact of disease, demographics, comorbidities and psoriasis characteristics (d < 0.337). Mean PsAID12 scores were 3.1 (SD 2.3) and 3.7 (SD 2.6) in the screen-positive and PsA groups, respectively. Compared with patients who screened negative for PsA, patients who screened positive exhibited higher rates of selected known predictors of PsA such as older age, longer psoriasis duration, nail disease and inverse psoriasis. The proportion of patients at PASS was 56% and 67% for the PsA and screen-positive groups, respectively. CONCLUSIONS: The similar profiles between screen-positive and PsA groups, in comparison with the screen-negative group, support observations of possible underdiagnosis of PsA and the increased impact of disease, especially musculoskeletal disease, among patients who screen positive for PsA. The high percentage of patients not at an acceptable symptom state in the PsA and screen-positive groups highlights the need to optimize care in PsA.

Prospective cohort study of psoriatic arthritis risk in patients with psoriasis in a real-world psoriasis registry.

BACKGROUND: The characteristics that predict the onset of psoriatic arthritis (PsA) among patients with psoriasis (PsO) may inform diagnosis and treatment. OBJECTIVE: To develop a model to predict the 2-year risk of developing PsA among patients with PsO. METHODS: This was a prospective cohort study of patients in the CorEvitas Psoriasis Registry without PsA at enrollment and with 24-month follow-up. Unregularized and regularized logistic regression models were developed and tested using descriptive variables to predict dermatologist-identified PsA at 24 months. Model performance was compared using the area under the receiver operating characteristic curve (AUC), sensitivity, and specificity. RESULTS: A total of 1489 patients were included. Nine unique predictive models were developed and tested. The optimal model, including Psoriasis Epidemiology Screening Tool (PEST), body mass index (BMI), modified Rheumatic Disease Comorbidity Index, work status, alcohol use, and patient-reported fatigue, predicted the onset of PsA within 24 months (AUC = 68.9%, sensitivity = 82.9%, specificity = 48.8%). A parsimonious model including PEST and BMI had similar performance (AUC = 68.8%; sensitivity = 92.7%, specificity = 36.5%). LIMITATIONS: PsA misclassification bias by dermatologists. CONCLUSION: PEST and BMI were important factors in predicting the development of PsA in patients with PsO over 2 years and thereby foundational for future PsA risk model development.

Drug survival of ixekizumab, TNF inhibitors, and other IL-17 inhibitors in real-world patients with psoriasis: The Corrona Psoriasis Registry.

To compare drug survival of ixekizumab to other IL-17 inhibitors (IL-17i) and TNF inhibitors (TNFi) among patients with psoriasis (PsO) in a real-world setting. Participants included adult PsO patients enrolled in the Corrona Psoriasis Registry who initiated ixekizumab, TNFi, or other IL-17i between 16 March 2016 to 10 August 2019 and completed ≥1 follow-up visit. Multivariable adjusted hazard ratios (HR) were calculated to estimate the risk for drug discontinuation in the ixekizumab group relative to the other drugs. Among the 1604 drug initiations, 552 initiated ixekizumab, 450 initiated TNFi, and 602 initiated other IL-17i. Mean age was 51 years, 49% were women, and 52% were obese (BMI > 30). Ixekizumab patients had a higher proportion of patients with PASI >12 at drug initiation (24%) than TNFi (15%) and other IL-17i (19%). Over a median of 11 months of follow-up, 723/1604 (45%) drug discontinuations occurred. Persistence of ixekizumab, TNFi, and other IL-17i at 24-months were 68%, 33%, and 46%, among biologic-naïve patients (n = 543), and 46%, 23%, and 36%, for biologic-experienced patients (n = 1061), respectively. Ixekizumab patients had a 64% lower risk of discontinuation vs TNFi (HR = 0.36; 95% CI 0.27-0.47) and a 31% lower risk vs other IL-17i (HR = 0.69, 95% CI 0.55-0.87) after adjustment for biologic experience and other covariates. HRs were similar when limited to patients with moderate-to-severe PsO (BSA > 3, PASI > 3, and IGA > 1, n = 1076) at initiation. In our study of real-world patients with PsO, initiators of ixekizumab had more prolonged drug survival than both initiators of TNFi and other IL-17i up to 2 years of follow-up.

Characterization of Patients with Psoriasis in Challenging-to-Treat Body Areas in the Corrona Psoriasis Registry.

BACKGROUND: Real-world studies evaluating patients with challenging-to-treat localizations of psoriasis (scalp, nail, and palmoplantar) are limited. OBJECTIVE: To characterize patients with versus without psoriasis in challenging-to-treat areas seen in routine US clinical practice. METHODS: This retrospective observational study included all adult patients with psoriasis enrolled in the Corrona Psoriasis Registry between April 2015 and May 2018 who initiated a biologic therapy at registry enrollment. Patients were stratified by the presence of scalp, nail, or palmoplantar psoriasis (nonmutually exclusive groups). Patient demographics, clinical char-acteristics, disease activity, and patient-reported outcome measures (pain, fatigue, itch, EuroQol visual analog scale [EQ VAS], Dermatology Life Quality Index [DLQI], and Work Productivity and Activity Impairment questionnaire [WPAI]) were assessed at registry enrollment and compared between patients with versus without each challenging-to-treat area using nonparametric Kruskal-Wallis tests for continuous variables and χ2 or Fisher exact tests for categorical variables. Generalized linear regression models were used to estimate differences in disease activity and patient-reported outcomes between patients with versus without each challenging-to-treat area. RESULTS: Among 2,042 patients with psoriasis (mean age [±SD], 49.6 ± 14.7 years; 51.5% male), 38.4% had psoriatic arthritis (PsA), 38.1% had scalp psoriasis, 16.0% had nail psoriasis, 10.9% had palmoplantar psoriasis, and 26.2% had a combination of ≥2 challenging-to-treat areas and PsA; only 34.2% had body plaque psoriasis without PsA or challenging-to-treat areas. Patients in all challenging-to-treat groups reported higher (mean [95% CI]) itch (scalp, 58.01 [57.62-58.40] vs. 54.35 [53.99-54.72]; nail, 56.42 [56.02-56.81] vs. 55.59 [55.20-55.97]; palmoplantar, 60.22 [59.86-60.59] vs. 55.15 [54.79-55.54]) and lower EQ VAS (scalp, 68.12 [67.78-68.48] vs. 69.46 [69.12-69.81]; nail, 66.21 [65.89-66.55] vs. 69.48 [69.14-69.83]; palmoplantar, 66.21 [66.07-66.75] vs. 69.29 [68.94-69.94]) scores than those without the respective challenging-to-treat localization. Patients with nail or palmoplantar psoriasis reported higher pain, fatigue, and DLQI scores than those without. Higher proportions of patients with scalp or palmoplantar psoriasis reported work impairment compared with those without. CONCLUSION: Two-thirds of patients with psoriasis who initiated biologic therapy had PsA and/or ≥1 challenging-to-treat area. Patients with challenging-to-treat areas had worse patient-reported outcome scores than those without, indicating a significant burden of challenging-to-treat areas on patients' quality of life.

Laboratory predictors of bleeding and the effect of platelet and RBC transfusions on bleeding outcomes in the PLADO trial.

Bleeding remains a significant problem for many thrombocytopenic hematology/oncology patients in spite of platelet transfusions. Factors that might contribute to bleeding were analyzed for 16 320 patient-days on or after their first platelet transfusion in 1077 adult patients enrolled in the Platelet Dose (PLADO) trial. All patients had a greatly increased risk of bleeding at platelet counts of ≤5 × 109/L (odds ratio [OR], 3.1; 95% confidence interval [CI], 2.0-4.8) compared with platelet counts ≥81 × 109/L. Platelet counts between 6 × 109/L and 80 × 109/L were also associated with a somewhat elevated bleeding risk in patients receiving allogeneic stem cell transplants (SCTs) or chemotherapy but not in those undergoing autologous SCTs. Other significant laboratory predictors of bleeding were hematocrit ≤25% (OR, 1.29; 95% CI, 1.11-1.49), activated partial thromboplastin time (aPTT) 30 to ≤50 seconds (OR, 1.40; 95% CI, 1.08-1.81; P = .01), aPTT >50 seconds (OR, 2.34; 95% CI, 1.54-3.56), international normalized ratio (INR) 1.2 to 1.5 (OR, 1.46; 95% CI, 1.17-1.83), and INR >1.5 (OR, 2.05; 95% CI, 1.43-2.95). Transfusion of either platelets or red blood cells (RBCs) on days with bleeding was often not sufficient to change bleeding outcomes on the following day. Because bleeding occurred over a wide range of platelet counts among patients undergoing allogeneic SCT or chemotherapy and because platelet transfusions may not prevent bleeding, other risk factors may be involved. These may include low hematocrit and coagulation abnormalities. This trial was registered at www.clinicaltrials.gov as #NCT00128713.

Persistence of tumor necrosis factor inhibitor or conventional synthetic disease-modifying antirheumatic drug monotherapy or combination therapy in psoriatic arthritis in a real-world setting.

This study described treatment patterns in a psoriatic arthritis (PsA) patient registry for new or ongoing tumor necrosis factor inhibitor (TNFi) monotherapy, conventional synthetic disease-modifying antirheumatic drug (csDMARD) monotherapy, or TNFi/csDMARD combination therapy. This retrospective analysis included adults with PsA who enrolled in the Corrona PsA/spondyloarthritis registry between March 21, 2013 (registry initiation), and January 31, 2017, and received an approved TNFi and/or csDMARD as "existing use" starting before registry entry or "initiated use" starting on/after registry entry. Therapy persistence was defined as index therapy use for ≥ 12 months without a treatment gap of ≥ 30 days. Among the evaluable patients with existing TNFi monotherapy (n = 251), csDMARD monotherapy (n = 225), and combination therapy (n = 214), 93, 87, and 87% were persistent for ≥ 12 months, and another 6, 5, and 5%, respectively, had no change with < 12 months of follow-up after first use. Among evaluable patients who initiated use of TNFi monotherapy (n = 26), csDMARD monotherapy (n = 35), and combination therapy (n = 15), 50, 43, and 53% were persistent for ≥ 12 months, and another 27, 20, and 20%, respectively, had no change with < 12 months of follow-up after first use. After initiation of index therapy, most changes (19-27% of patients) were discontinuation; 4-13% switched biologic therapy during follow-up. The results of this analysis of real-world treatment patterns in a PsA patient registry suggest that nonpersistence for TNFi monotherapy, csDMARD monotherapy, or TNFi/csDMARD combination therapy occurs more commonly after initiation of therapy than in patients with existing therapy. Trial registration: NCT02530268.

WBC alloimmunization: effects on the laboratory and clinical endpoints of therapeutic granulocyte transfusions.

BACKGROUND: Although the subject of many previous studies, the importance of white blood cell (WBC) alloimmunization in granulocyte transfusion therapy has not been settled. In this study, we report the results of the effects of WBC antibodies in the RING (Resolving Infection in Neutropenia with Granulocytes) study, a randomized controlled trial comparing the efficacy of daily granulocyte transfusion therapy plus antimicrobials versus antimicrobials alone; the primary outcome results have been published previously. STUDY DESIGN AND METHODS: One hundred fourteen subjects were enrolled in the study. Serum samples for WBC antibody determination were obtained from each subject at baseline and at 2 and 6 weeks. One hundred subjects had at least one antibody test result. Samples were tested for human leukocyte antigen (HLA) Class I and Class II antibodies as well as for granulocyte-specific antibodies using granulocyte agglutination and immunofluorescence techniques. All testing was performed at a central laboratory. RESULTS: Baseline WBC alloimmunization was modest, depending somewhat on the assay. Seroconversion during the study was slightly higher in the granulocyte transfusion arm, but the differences were not statistically significant. There was no demonstrable effect of the presence of alloimmunization on the primary outcome (survival and microbial response at 42 days), the occurrence of transfusion reactions (either overall or pulmonary), or posttransfusion neutrophil increments. CONCLUSION: The presence or development of WBC antibodies had no demonstrable effect on any clinical aspect of granulocyte transfusion therapy. It appears that, at least in the patient population studied, there is no evidence suggesting need for concern about recipient WBC alloimmunization when prescribing granulocyte transfusions.

Efficacy of transfusion with granulocytes from G-CSF/dexamethasone-treated donors in neutropenic patients with infection.

High-dose granulocyte transfusion therapy has been available for 20 years, yet its clinical efficacy has never been conclusively demonstrated. We report here the results of RING (Resolving Infection in Neutropenia with Granulocytes), a multicenter randomized controlled trial designed to address this question. Eligible subjects were those with neutropenia (absolute neutrophil count <500/µL) and proven/probable/presumed infection. Subjects were randomized to receive either (1) standard antimicrobial therapy or (2) standard antimicrobial therapy plus daily granulocyte transfusions from donors stimulated with granulocyte colony-stimulating factor (G-CSF) and dexamethasone. The primary end point was a composite of survival plus microbial response, at 42 days after randomization. Microbial response was determined by a blinded adjudication panel. Fifty-six subjects were randomized to the granulocyte arm and 58 to the control arm. Transfused subjects received a median of 5 transfusions. Mean transfusion dose was 54.9 × 10(9) granulocytes. Overall success rates were 42% and 43% for the granulocyte and control groups, respectively (P > .99), and 49% and 41%, respectively, for subjects who received their assigned treatments (P = .64). Success rates for granulocyte and control arms did not differ within any infection type. In a post hoc analysis, subjects who received an average dose per transfusion of ≥0.6 × 10(9) granulocytes per kilogram tended to have better outcomes than those receiving a lower dose. In conclusion, there was no overall effect of granulocyte transfusion on the primary outcome, but because enrollment was half that planned, power to detect a true beneficial effect was low. RING was registered at www.clinicaltrials.gov as #NCT00627393.

Patterns in the Sequential Treatment of Patients With Rheumatoid Arthritis Starting a Biologic or Targeted Synthetic Disease-Modifying Antirheumatic Drug: 10-Year Experience From a US-Based Registry.

OBJECTIVE: Developing and evaluating new treatment guidelines for rheumatoid arthritis (RA) based on observational data requires a quantitative understanding of patterns in current treatment practice with biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). METHODS: We used data from the CorEvitas RA registry to study patients starting their first b/tsDMARD therapy, defined as the first line of therapy, between 2012 and the end of 2021. We identified treatment patterns as unique sequences of therapy changes following and including the first-line therapy. Therapy cycling was defined as switching back to a treatment from a previously used therapeutic class. RESULTS: A total of 6015 b/tsDMARD-naïve patients (77% female) were included in the analysis. Their median age was 58 years, and their median disease duration was 3 years. In 2012-2014, 80% of the patients started a tumor necrosis factor inhibitor (TNFi) as their first b/tsDMARD. However, the use of TNFi decreased in favor of Janus kinase inhibitors since 2015. Although the number of treatment patterns was large, therapy cycling was relatively common. For example, 601 patterns were observed among 1133 patients who changed therapy at least four times, of whom 85.3% experienced therapy cycling. Furthermore, the duration of each of the first three lines of therapy decreased over the past decade. For example, the median duration of the first-line therapy was 153 days in 2018-2021 compared to 208 days in 2015-2017 (P < 0.001). CONCLUSION: First-line therapy was almost always TNFi, but diversity in treatment choice was high after that. This practice variation allows for proposing and evaluating new guidelines for sequential treatment of RA. It also presents statistical challenges to compare patients with different treatment sequences.

Outcomes of Biologic Use in Asian Compared with Non-Hispanic White Adult Psoriasis Patients from the CorEvitas Psoriasis Registry.

INTRODUCTION: Real-world data are limited comparing Asian and White patients with psoriasis using biologic therapy. This study compared the 6-month effectiveness of biologic therapy between Asian and White plaque patients with psoriasis in the CorEvitas Psoriasis Registry. METHODS: Analyses included biologic initiations and 6-month follow-up visits from self-identified Asian (n = 293) and White (n = 2314) patients in the USA/Canada (4/2015-4/2020). Outcomes included: Psoriasis Area Severity Index (PASI) 75, disease activity measures [body surface area (BSA) ≤ 1, BSA ≤ 3, PASI90, PASI100, Investigator's Global Assessment (IGA) 0/1], and patient-reported outcomes [Dermatology Life Quality Index (DLQI) 0/1, itch, fatigue, skin pain, EuroQoL visual analog scale (EQ-VAS), patient global assessment, Work Productivity Activity and Impairment (WPAI) domains]. Unadjusted regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI) for achievement of binary outcomes and difference in mean change in continuous outcomes (ß, 95% CI) at 6 months, followed by adjustment for age, sex, body mass index, alcohol, smoking, health insurance, education, comorbidities, scalp psoriasis morphology, psoriatic arthritis, biologic class, previous biologics, and baseline outcome value. RESULTS: Asians had lower proportions of women (32.8% versus 49.1%) and obesity (27.3% versus 54.5%), and higher proportions on Medicaid (19.9% versus 8.8%), graduated college (50.9% versus 40.1%) and never smoked (67.1% versus 44.1%). In unadjusted analyses, Asians had 52% higher odds of achieving PASI75 versus White patients (OR 1.52; 95% CI 1.15, 2.02). After adjustment, the association was attenuated (OR 1.11; 0.81, 1.52). Secondary outcomes experienced similar patterns except for DLQI: Asians had 33% lower odds of achieving DLQI 0/1 in both the unadjusted (OR 0.67; 0.50, 0.90) and adjusted (OR 0.67; 0.49, 0.92) models. CONCLUSION: Unadjusted differences in biologic therapy effectiveness between Asians compared with White patients were likely explained by differences in demographic, lifestyle, and psoriatic disease characteristics between groups. However, Asians still experienced lesser improvements in skin-related quality of life, even after adjustment.

Patterns in the sequential treatment of rheumatoid arthritis patients starting a b/tsDMARD: 10-year experience from a US-based registry.

Objectives: Developing and evaluating new treatment guidelines for rheumatoid arthritis (RA) based on observational data requires a quantitative understanding of patterns in current treatment practice with biologic and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs). Methods: We used data from the CorEvitas RA registry to study patients starting their first b/tsDMARD therapy-defined as the first line of therapy-between 2012 and the end of 2021. We identified treatment patterns as unique sequences of therapy changes following and including the first-line therapy. Therapy cycling was defined as switching back to a treatment from a previously used therapeutic class. Results: 6,015 b/tsDMARD-naive patients (77% female) were included in the analysis. Their median age was 58 years, and their median disease duration was 3 years. In 2012-2014, 80% of the patients started a tumor necrosis factor inhibitor (TNFi) as their first b/tsDMARD. However, the use of TNFi decreased in favour of Janus kinase inhibitors (JAKi) since 2015. While the number of treatment patterns was large, therapy cycling was relatively common. For example, 601 patterns were observed among 1133 patients who changed therapy at least four times, of whom 85.3% experienced therapy cycling. Furthermore, the duration of each of the first three lines of therapy decreased over the past decade. Conclusion: First-line therapy was almost always TNFi, but diversity in treatment choice was high after that. This practice variation allows for proposing and evaluating new guidelines for sequential treatment of RA. It also presents statistical challenges to compare subjects with different treatment sequences.

Outcomes in Ixekizumab Patients Following Exposure to Secukinumab and Other Biologics in the CorEvitas Psoriasis Registry.

INTRODUCTION: The aim of this work is to describe real-world biologic-experienced psoriasis patients initiating ixekizumab by prior biologic therapy status and compare the effectiveness of ixekizumab between patients who previously failed secukinumab and those who failed other biologics. We hypothesized that (1) clinical outcomes and patient-reported outcomes would improve following a switch to IXE, and (2) there would be no differences in responses between patients who previously failed secukinumab and those who failed other biologics. METHODS: Participants (n = 419) included adult psoriasis patients enrolled in the CorEvitas Psoriasis Registry through 9/10/20 who switched to ixekizumab after discontinuing another biologic. Patients were classified by the biologic used immediately prior to ixekizumab and reason for discontinuation: prior secukinumab failure; prior secukinumab non-failure; prior other biologic failure; and prior other biologic non-failure. Discontinuations for efficacy reasons were considered failures; all others were considered non-failures. Baseline descriptive statistics were calculated. Multivariable Poisson regression models estimated the likelihood of response of other failure relative to secukinumab failure. RESULTS: Mean age was 51 years; 48% were women. Psoriasis disease characteristics were similar across prior biologic groups. At 6-month follow-up, disease severity improved for all who initiated ixekizumab after discontinuing another biologic. Secukinumab failure patients who switched to ixekizumab achieved BSA ≤ 1 (49%), BSA ≤ 3 (59%), PASI75 (46%), PASI ≤ 3 (64%), and IGA ≤ 1 (40%). Other failure patients achieved BSA ≤ 1 (55%), BSA ≤ 3 (72%), PASI75 (59%), PASI ≤ 3 (74%), and IGA ≤ 1 (54%). In regression modeling, we observed patients in the other biologics failure group had an increased likelihood of achieving response for BSA ≤ 3, PASI75, PASI90, PASI100, and IGA ≤ 1 compared to patients who failed secukinumab. CONCLUSIONS: These findings suggest that patients with psoriasis who switch to ixekizumab after discontinuing another biologic demonstrate improvement in disease severity after six months. Patients who discontinued biologics other than secukinumab may be more likely to respond to ixekiziumab compared to those who switched from secukinumab.

Disease response and patient-reported outcomes among initiators of ixekizumab.

OBJECTIVES: There is limited real-world evidence on using ixekizumab in psoriasis patients. Therefore, we characterized patients with psoriasis initiating ixekizumab and report 6-month changes in disease and patient-reported outcomes. METHODS: Adult patients with psoriasis who initiated ixekizumab and completed a 6-month follow-up visit were enrolled from the Corrona Psoriasis Registry. Disease characteristics and outcomes were assessed at ixekizumab initiation. Outcomes included the mean 6-month change in Psoriasis Area and Severity Index (PASI), body surface area (BSA), Investigator Global Assessment (IGA), and IGA*BSA. RESULTS: From baseline to follow-up in all patients (n = 136), means decreased for IGA*BSA (-45.5) and BSA (-12.4), and a higher % achieved an absolute PASI ≤ 5 (84.6%), BSA 0-3 (72.1%), and IGA 0/1 (50.7%). Within stratified groups, means decreased for PASI <12 for IGA*BSA (-21.1) and BSA (-6.3); PASI≥12 for IGA*BSA (-94.8) and BSA (-24.6); weight <100 kg for IGA*BSA (-45.1) and BSA (-12.4); weight ≥100 kg for IGA*BSA (-46.2) and BSA (-12.3); concomitant PsA for IGA*BSA (-56.0) and BSA (-15.3); and in no concomitant PsA for IGA*BSA (-36.9) and BSA (-10.0). CONCLUSIONS: We provide real-world evidence on the benefits of ixekizumab for treating psoriasis, regardless of baseline disease severity, weight, or concomitant PsA.

Disease Burden and Patient-Reported Outcomes Among Ulcerative Colitis Patients According to Therapy at Enrollment Into CorEvitas' Inflammatory Bowel Disease Registry.

Background: To evaluate disease burden and patient-reported outcomes (PROs) of ulcerative colitis (UC) patients at enrollment into CorEvitas' Inflammatory Bowel Disease Registry by therapy class. Methods: Between May 3, 2017 and September 3, 2019, 773 UC registry patients were categorized by therapy class at enrollment: patients on 5-aminosalicylic acids (5-ASAs) only (n = 290), and patients on biologics/Janus kinase inhibitors (JAKi) alone or in combination with 5-ASAs or immunosuppressant therapies (BIO/JAKi) (n = 315). To quantify between group differences, the mean/proportional differences and corresponding 95% CIs were calculated. Results: Among 605 UC patients at enrollment, BIO/JAKi patients were younger (44.1 vs. 50.9 years) more were female (58.0% vs. 49.7%), had lower remission (45.4% vs. 60.0%), had more moderate/severe disease (16.5% vs. 7.1%), experienced less proctitis (10.5% vs. 22.1%), but more pancolitis (54.6% vs. 34.1%), more corticosteroid experience (70.8% vs. 44.5%), previous biologic experience (1 prior: 21.6% vs. 2.4%; 2+ prior: 12.1% vs. 0.3%), and shorter duration of current UC therapy (1.6 vs. 3.5 years) than 5-ASAs patients. BIO/JAKi patients had higher current employment than 5-ASAs patients (70.7% vs. 62.4%) and higher mean Work Productivity and Activity Impairment (WPAI) domains for absenteeism (7.3 vs. 2.8) and activity impairment (22.0 vs. 17.5). Conclusions: Among UC patients in a real-world setting, BIO/JAKi patients had less remission, more moderate-to-severe disease, and worse PROs than 5-ASAs patients. These results suggest that despite increased therapeutic options, patients with UC currently being treated with biologics or JAKi may still experience disease burden and continued unmet needs.

Understanding characteristics of patients newly initiating ixekizumab: findings from the Corrona Psoriasis Registry.

Background: Real-world data on patients newly initiating ixekizumab is limited. Our study describes the characteristics of patients who initiated ixekizumab and other biologics for psoriasis treatment in North American dermatological practices. Materials & methods: Characteristics of patients ascertained at registry enrollment are described via means and frequencies. Results: Compared with other biologic initiators, ixekizumab initiators had: longer disease duration (17.1 vs 15.1 years); more were considered least severe by body surface area (33 vs 26%); moderate-to-severe by IGA (56 vs 48%); were biologic-experienced (80 vs 52%); obese (54 vs 47%); and experienced greater impact in work productivity (5.3 vs 2.9%) versus other biologic initiators. Conclusion: Psoriasis patients initiating ixekizumab had more severe disease, biologic experience, and worse patient-reported outcomes than those initiating other biologics.

Psoriasis Severity, Comorbidities, and Treatment Response Differ among Geographic Regions in the United States.

Little is known about how psoriatic disease characteristics and treatment outcomes differ geographically in the United States. Our aim was to explore real-world, geographic variations in the use of biologic classes and outcomes within the Corrona Psoriasis Registry. Patient demographics and disease characteristics were assessed at biologic initiation and at 6 months. Logistic regressions were conducted to evaluate the odds of achieving targeted outcomes for seven United States geographic regions. We examined 737 biologic initiations among 717 patients. IL-17 inhibitors were used most frequently (45%), followed by IL-12‒IL-23 and IL-23 inhibitors (38%) and TNF inhibitors (17%). The proportions of patients with obesity (body mass index > 30) and very severe psoriasis (body surface area > 20) were greatest in the East South Central and West South Central regions. After adjusting for age, sex, race, body mass index, and baseline body surface area, decreased odds of achieving 75% improvement in PASI at 6 months were observed among patients in the East South Central (OR = 0.47, 95% confidence interval = 0.28-0.79, P = 0.004), West South Central (OR = 0.43, 95% confidence interval = 0.22-0.87, P = 0.019), and Pacific (OR = 0.49, 95% confidence interval = 0.28-0.84, P = 0.010) regions compared with those observed among patients in the Northeast. The East South Central and West South Central regions may have the greatest frequencies of very severe disease burden and, along with the Pacific region, may be less likely to achieve targeted response within 6 months of initiating biologic therapy.

No Obesity Paradox in Pediatric Patients With Dilated Cardiomyopathy.

OBJECTIVES: This study aimed to examine the role of nutrition in pediatric dilated cardiomyopathy (DCM). BACKGROUND: In adults with DCM, malnutrition is associated with mortality, whereas obesity is associated with survival. METHODS: The National Heart, Lung, and Blood Institute-funded Pediatric Cardiomyopathy Registry was used to identify patients with DCM and categorized by anthropometric measurements: malnourished (MN) (body mass index [BMI] <5% for age ≥2 years or weight-for-length <5% for <2 years), obesity (BMI >95% for age ≥2 years or weight-for-length >95% for <2 years), or normal bodyweight (NB). Of 904 patients with DCM, 23.7% (n = 214) were MN, 13.3% (n=120) were obese, and 63.1% (n=570) were NB. RESULTS: Obese patients were older (9.0 vs. 5.7 years for NB; p < 0.001) and more likely to have a family history of DCM (36.1% vs. 23.5% for NB; p = 0.023). MN patients were younger (2.7 years vs. 5.7 years for NB; p < 0.001) and more likely to have heart failure (79.9% vs. 69.7% for NB; p = 0.012), cardiac dimension z-scores >2, and higher ventricular mass compared with NB. In multivariable analysis, MN was associated with increased risk of death (hazard ratio [HR]: 2.06; 95% confidence interval [CI]: 1.66 to 3.65; p < 0.001); whereas obesity was not (HR: 1.49; 95% CI: 0.72 to 3.08). Competing outcomes analysis demonstrated increased risk of mortality for MN compared with NB (p = 0.03), but no difference in transplant rate (p = 0.159). CONCLUSIONS: Malnutrition is associated with increased mortality and other unfavorable echocardiographic and clinical outcomes compared with those of NB. The same effect of obesity on survival was not observed. Further studies are needed investigating the long-term impact of abnormal anthropometric measurements on outcomes in pediatric DCM.
