RESUMEN
Functional magnetic resonance imaging (fMRI) captures rich physiological and neuronal information that can offer insights into neurofluid dynamics, vascular health, and waste clearance function. The availability of cerebral vessel segmentation could facilitate fluid dynamics research in fMRI. However, without magnetic resonance angiography scans, cerebral vessel segmentation is challenging and time-consuming. This study leverages cardiac-induced pulsatile fMRI signal to develop a data-driven, automatic segmentation of large cerebral arteries and the superior sagittal sinus (SSS). The method was validated in a local dataset by comparing it to ground truth cerebral artery and SSS segmentations. Using the Human Connectome Project (HCP) aging dataset, the method's reproducibility was tested on 422 participants aged 36 to 100 years, each with four repeated fMRI scans. The method demonstrated high reproducibility, with an intraclass correlation coefficient > 0.7 in both cerebral artery and SSS segmentation volumes. This study demonstrates that the large cerebral arteries and SSS can be reproducibly and automatically segmented in fMRI datasets, facilitating the investigation of fluid dynamics in these regions.
RESUMEN
BACKGROUND: Tildrakizumab is a humanized anti-interleukin-23 p19 monoclonal antibody approved for the treatment of moderate-to-severe plaque psoriasis. This report describes real-world effectiveness and safety of tildrakizumab through 64 weeks of treatment. METHODS: In this Phase 4, multicenter, uncontrolled, open-label trial (NCT03718299), adults with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at weeks 0 and 4 and every 12 weeks thereafter through week 52. Effectiveness was assessed from body surface area (BSA) affected and static Physician Global Assessment (sPGA) through week 64 and Psoriasis Area and Severity Index (PASI) through week 52. Adverse events are reported. RESULTS: Of 55 patients enrolled, 45 completed the study and 36 received all doses of tildrakizumab. From baseline to week 64, mean +/- standard deviation BSA decreased by 83.1% (from 14.5 +/- 11.5 to 2.1 +/- 3.6) and sPGA by 67.6% (from 3.2 +/- 0.6 to 1.0 +/- 1.0); sPGA x BSA decreased by 89.6% (from 47.0 +/- 41.5 to 4.6 +/- 9.4; all P<0.001). PASI scores decreased compared to baseline at weeks 4, 16, 28, and 52 (P<0.001). For PASI responses at week 52 compared with baseline, 87.0% achieved greater than or equal to 75% improvement, 56.5% achieved greater than or equal to 90% improvement, and 32.6% achieved 100% improvement. Of 85 treatment-emergent adverse events in 34/55 patients, none were considered related to tildrakizumab treatment. CONCLUSIONS: Tildrakizumab treatment was effective in adult patients with moderate-to-severe plaque psoriasis in real-world settings, with no new safety signals.

BACKGROUND: Tildrakizumab is an anti-interleukin-23 p19 monoclonal antibody approved for the treatment of moderate-to-severe plaque psoriasis. This report describes final primary results of a 64-week real-world study of the effect of tildrakizumab on patients' health-related quality of life (HRQoL). MATERIALS AND METHODS: In this open-label phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. The primary endpoint was improvement from baseline in HRQoL measured by Psychological General Well-Being Index (PGWBI) total score at weeks 28 and 52. Secondary HRQoL endpoints included change from baseline in Dermatology Life Quality Index (DLQI) score through week 64. Missing data were not imputed. RESULTS: Of 55 patients enrolled, 45 were assessed at week 64. Mean ± standard deviation (SD) total PGWBI score improved from 78.1 ± 14.1 at baseline to 85.2 ± 12.0 at week 52 (p < .001). Mean ± SD DLQI score improved from 9.4 ± 5.2 at baseline to 2.0 ± 2.6 (p < .001) at week 64 with 62.2% of patients having a DLQI score of 0 or 1 at week 64. CONCLUSIONS: Tildrakizumab improved long-term HRQoL in patients with psoriasis in a real-world setting.

INTRODUCTION: Brodalumab is a human interleukin-17 receptor A antagonist indicated for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy and have failed to respond or have lost response to other systemic therapies. Although the US prescribing information for brodalumab includes a boxed warning regarding suicidal ideation and behavior, no causal association has been demonstrated. Here, we summarize 5 years of pharmacovigilance data, from August 15, 2017, through August 14, 2022, reported to Ortho Dermatologics by US patients and healthcare providers. METHODS: Prevalence of the most common adverse events (AEs) listed in the brodalumab package insert (incidence ≥ 1%) and AEs of special interest are described. Brodalumab exposure was estimated as the time from the first to last prescription-dispensing authorization dates. Data were collected from 4744 patients in the USA, with an estimated exposure of 5815 patient-years. RESULTS: Over 5 years, 11 cases of adjudicated major adverse cardiovascular events were reported (0.23 events/100 patients), a rate lower than that experienced by patients in the international Psoriasis Longitudinal Assessment and Registry. There were 106 serious infections. No serious fungal infections were reported. There were 40 confirmed and 2 suspected COVID-19 cases, with no new COVID-19-related deaths. Of 49 reported malignancies among 42 patients, 3 were deemed possibly related to brodalumab. No completed suicides and no new suicidal attempts were reported. CONCLUSION: Five-year pharmacovigilance data are consistent with the established safety profile reported in long-term clinical trials and previous pharmacovigilance reports, with no new safety signals.
Brodalumab is an injectable treatment approved for moderate-to-severe plaque psoriasis in adults who lacked response to previous treatments. In the USA, brodalumab is only available under a Risk Evaluation and Mitigation Strategy for increased suicidality risks; however, findings from 5 years of real-world safety data have demonstrated a lack of association. In this report, we discuss safety findings reported by US patients and healthcare providers for 4744 patients treated with brodalumab over 5 years. Joint pain (known as arthralgia) was the most common safety finding, with 122 cases reported over 5 years. Other safety findings of interest across 5 years included 106 serious infections (defined as prolonged infections or infections requiring treatment), 54 cases of depression, 49 cases of cancer (in 42 patients), 40 confirmed cases of COVID-19, and 11 cases of major cardiovascular events (such as stroke or heart attack). No completed suicides occurred throughout 5 years, and no new suicidal attempts were reported in year 5. In indirect comparisons with safety data from patients with psoriasis receiving or eligible to receive similar treatments, brodalumab was not associated with an increased risk of serious infection, cancer, major cardiovascular events, or inflammatory bowel disease. Taken together, these data are consistent with safety findings from long-term clinical trials and previous safety reports of brodalumab.
RESUMEN
INTRODUCTION: Plaque psoriasis is a chronic condition that may impact patients' work productivity. Tildrakizumab, an interleukin-23 p19 inhibitor, is approved for treatment of moderate-to-severe plaque psoriasis in adults. However, the effect of tildrakizumab treatment on work productivity in patients with psoriasis is not well characterized. METHODS: In this multicenter, open-label, uncontrolled phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. Patients completed the Work Productivity and Activity Impairment Questionnaire: Psoriasis (WPAI:PSO) at baseline and every 12 weeks from week 16 through week 64. The following four domains of the WPAI:PSO were examined: absenteeism (percentage of time missed from work due to psoriasis), presenteeism (percentage reduction of productivity while at work due to psoriasis), total activity impairment (percentage impairment in activities other than work due to psoriasis), and total work productivity impairment (total percentage of work impairment from both absenteeism and presenteeism due to psoriasis). Missing data were not imputed. RESULTS: Of the 55 patients enrolled, 31 patients completed all domains of the WPAI:PSO at week 64. From baseline to week 64, respectively, mean ± standard deviation (SD) scores improved for presenteeism (20.5 ± 21.7 to 2.6 ± 5.8; P < 0.001), total activity impairment (29.5 ± 26.6 to 4.4 ± 9.4; P < 0.001), and total work productivity impairment (20.9 ± 22.2 to 2.6 ± 5.8; P < 0.001). The mean ± SD score for absenteeism decreased from 1.1 ± 5.7 at baseline to 0.0 ± 0.0 at week 64, but this change was not statistically significant. CONCLUSION: Tildrakizumab treatment mitigated work productivity loss due to psoriasis as measured by the presenteeism, total activity impairment, and total work productivity impairment domains of the WPAI:PSO. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03718299.
RESUMEN
BACKGROUND: Systemic immunomodulatory agents are indicated in the treatment of moderate-to-severe plaque psoriasis and psoriatic arthritis. Perioperative use of these medications may increase the risk of surgical site infection (SSI) and complication. OBJECTIVE: To evaluate the risk of SSI and complication in patients with chronic autoimmune inflammatory disease receiving immunomodulatory agents (tumor necrosis factor-alfa [TNF-α] inhibitors, interleukin [IL] 12/23 inhibitor, IL-17 inhibitors, IL-23 inhibitors, cytotoxic T-lymphocyte-associated antigen-4 costimulator, phosphodiesterase-4 inhibitor, Janus kinase inhibitors, tyrosine kinase 2 inhibitor, cyclosporine (CsA), and methotrexate [MTX]) undergoing surgery. METHODS: We performed a search of the MEDLINE PubMed database of patients with chronic autoimmune inflammatory disease on immune therapy undergoing surgery. RESULTS: We examined 48 new or previously unreviewed studies; the majority were retrospective studies in patients with rheumatoid arthritis and inflammatory bowel disease. CONCLUSION: For low-risk procedures, TNF-α inhibitors, IL-17 inhibitors, IL-23 inhibitors, ustekinumab, abatacept, MTX, CsA, and apremilast can safely be continued. For intermediate- and high-risk surgery, MTX, CsA, apremilast, abatacept, IL-17 inhibitors, IL-23 inhibitors, and ustekinumab are likely safe to continue; however, a case-by-case approach is advised. Acitretin can be continued for any surgery. There is insufficient evidence to make firm recommendations on tofacitinib, upadacitinib, and deucravacitinib.

BACKGROUND: For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. OBJECTIVE: To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. METHODS: Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. RESULTS: Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. LIMITATIONS: Studies regarding infection rates after vaccination are lacking. CONCLUSION: Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases.
