Exploring the Chronic Nature of Generalized Pustular Psoriasis [Podcast

Generalized pustular psoriasis (GPP) is a rare, chronic, inflammatory skin disease characterized by persistent symptoms and sudden flares of painful, sterile pustules, and may be accompanied by systemic inflammation. Ongoing symptoms of GPP can have a serious impact on patient quality of life, morbidity, and mortality, and severe flares may be life-threatening if left untreated. Guidelines have been developed for the treatment of GPP flares; however, health care professionals and patients are lacking guidance on the management of long-term, persistent symptoms of GPP. Spesolimab is the only FDA-approved treatment for GPP and is approved for use in adults and pediatric patients aged 12 years or older and weighing at least 40 kg. Spesolimab recently gained FDA approval as a subcutaneous injection to treat GPP when patients are not experiencing a flare. In this podcast episode, we discuss what is known about the chronic disease burden of GPP and how persistent symptoms affect quality of life when patients are not experiencing a flare. We address the need for treatment guidelines for chronic GPP and discuss the results of the EFFISAYIL® 2 clinical trial, which led to the approval of the subcutaneous formulation of spesolimab to treat GPP when patients are not experiencing a flare. Finally, we discuss what can be done to improve the treatment of patients with chronic GPP, both while experiencing a flare, and while living with persistent symptoms.

Variation in nutritional therapy practices: results of a survey on nutritional management of severe inflammatory bowel disease.

The optimal nutritional management during a severe flare of inflammatory bowel disease is uncertain. The goal of this study was to describe variations in nutritional practices between different countries, professions and types of hospitals, as well as between ulcerative colitis (UC) and Crohn's disease (CD). In this cross-sectional study, a novel questionnaire was distributed in the ECCO Congress 2022 and via ECCO country representatives. The survey was completed by 313 participants. In total, 68% of the respondents were physicians. No specific nutritional screening tool was used by 45% of respondents. Almost a quarter of respondents reported less than 25% of patients being assessed by a dietitian in the first 3 days of a flare. The most common form of nutritional therapy was oral nutritional supplements (ONS) with easy-to-digest food. Total parenteral nutrition (TPN) was used by 10% of respondents for UC patients and 7% for CD. Energy intake, stool frequency and inflammatory biomarkers were the most common factors in determining when to change nutritional therapy. There were significant differences between different countries and health care professions for all the outcomes (P < 0.05). Nutritional management did not generally vary according to hospital type (university vs. general). During the first 3 days of a flare, a diet consisting exclusively of ONS was significantly more frequently used for CD than UC (P = 0.018). Otherwise, similar nutritional therapy strategies were reported for CD and UC, including using TPN to a similar extent. There is significant variation in nutritional management practices. Country is the main determinant of differences in practice.

Development of an Educational Website for Patients With Cancer and Preexisting Autoimmune Diseases Considering Immune Checkpoint Blockers: Usability and Acceptability Study.

Patients with cancer and an underlying autoimmune disease who are considering immune checkpoint blockers (ICBs) need to know about the benefits and risks of severe immune-related adverse events and flares of the autoimmune condition. This study aims to develop and alpha test an educational website for patients with cancer. Learning topics, images, and website architecture (including flow and requirements) were developed and iteratively reviewed by members of a community scientist program, a patient advisory group, and content experts. Alpha testing was performed, measuring the site's usability using the Suitability Assessment of Materials and its acceptability using the Ottawa Acceptability Measure. The website included a home page; general information about ICBs; comprehensive modules on the benefits and risks of ICBs for patients with cancer and preexisting autoimmune diseases; general wellness information; and features such as a quiz, additional resources, and a glossary. For the alpha testing, 9 users assessed the newly developed website. Patient reviewers (n=5) had rheumatoid arthritis, Crohn disease, Sjogren syndrome, or vasculitis. Health care provider reviewers (n=4) were medical oncologists or rheumatologists. The median Suitability Assessment of Materials rating was 75 (IQR 70-79; range 0-100) for patients versus 66 (IQR 57-72; range 0-100) for providers (scores ≥70 indicate no substantial changes needed). Recommendations for improvement, mostly involving navigation and accessibility, were addressed. All participants expressed that the website was acceptable and balanced in terms of discussion of benefits and harms. Because half (2/4, 50%) of the providers suggested we increase the amount of information, we extended the content on the impact of having an autoimmune disease when considering ICB treatment, the probability of flares, and the management of flares in this context. The feedback led to minor revisions to enhance readability, navigation, and accessibility, ensuring the website's suitability as a decision-making aid. The newly developed website could become a supporting tool to facilitate patient-physician discussion regarding ICBs.

Clinical Trial Design Considerations for Hospitalised Patients With Ulcerative Colitis Flares and Application to Study Hyperbaric Oxygen Therapy in the NIDDK HBOT-UC Consortium.

Patients with ulcerative colitis (UC) who are hospitalised for acute severe flares represent a high-risk orphan population. To provide guidance for clinical trial design methodology in these patients. We created a multi-centre consortium to design and conduct a clinical trial for a novel therapeutic intervention (hyperbaric oxygen therapy) in patients with UC hospitalised for moderate-severe flares. During planning, we identified and addressed specific gaps for inclusion/exclusion criteria; disease activity measures; pragmatic trial design considerations within care pathways for hospitalised patients; standardisation of care delivery; primary and secondary outcomes; and sample size and statistical analysis approaches. The Truelove-Witt criteria should not be used in isolation. Endoscopy is critical for defining eligible populations. Patient-reported outcomes should include rectal bleeding and stool frequency, with secondary measurement of urgency and nocturnal bowel movements. Trial design needs to be tailored to care pathways, with early intervention focused on replacing and/or optimising responsiveness to steroids and later interventions focused on testing novel rescue agents or strategies. The PRECIS-2 framework offers a means of tailoring to local populations. We provide standardisation of baseline testing, venous thromboprophylaxis, steroid dosing, discharge criteria and post-discharge follow-up to avoid confounding by usual care variability. Statistical considerations are provided given the small clinical trial nature of this population. We provide an outline for framework decisions made for the hyperbaric oxygen trial in patients hospitalised for UC flares. Future research should focus on the remaining gaps identified.

Integrating transcriptomics, eQTL, and Mendelian randomization to dissect monocyte roles in severe COVID-19 and gout flare.

There are considerable similarities between the pathophysiology of gout flare and the dysregulated inflammatory response in severe COVID-19 infection. Monocytes are the key immune cells involved in the pathogenesis of both diseases. Therefore, it is critical to elucidate the molecular basis of the function of monocytes in gout and COVID-19 in order to develop more effective therapeutic approaches. The single-cell RNA sequencing (scRNA-seq), large-scale genome-wide association studies (GWAS), and expression quantitative trait loci (eQTL) data of gout and severe COVID-19 were comprehensively analyzed. Cellular heterogeneity and intercellular communication were identified using the scRNA-seq datasets, and the monocyte-specific differentially expressed genes (DEGs) between COVID-19, gout and normal subjects were screened. In addition, the correlation of the DEGs with severe COVID-19 and gout flare was analyzed through GWAS statistics and eQTL data. The scRNA-seq analysis exhibited that the proportion of classical monocytes was increased in both severe COVID-19 and gout patient groups compared to healthy controls. Differential expression analysis and MR analysis showed that NLRP3 was positively associated with the risk of severe COVID-19 and involved 11 SNPs, of which rs4925547 was not significantly co-localized. In contrast, IER3 was positively associated with the risk of gout and involved 9 SNPs, of which rs1264372 was significantly co-localized. Monocytes have a complex role in gout flare and severe COVID-19, which underscores the potential mechanisms and clinical significance of the interaction between the two diseases.

Mycophenolate Mofetil and New-Onset Systemic Lupus Erythematosus

Anti-double-stranded DNA (dsDNA) antibody has been reported to have a close relationship with systemic lupus erythematosus (SLE) flares and participates in the pathogenesis of lupus nephritis (LN) as well as causing damage to other organs. However, whether early use of mycophenolate mofetil (MMF) could prevent SLE flares is not clear. To assess the efficacy and safety of MMF plus prednisone and hydroxychloroquine sulfate compared with prednisone and hydroxychloroquine sulfate alone in patients with SLE. This investigator-initiated, multicenter, observer-blinded randomized clinical trial enrolled 130 participants aged 18 to 65 years and was conducted in 3 hospitals across China. Treatment-naive patients with newly diagnosed SLE, a high titer of anti-dsDNA antibody, and no major organ involvement were included. The study was started September 1, 2018, and the follow-up was completed September 30, 2021. Data were analyzed from December 1, 2021, to March 31, 2022. Patients were randomized 1:1 to receive oral prednisone (0.5 mg/kg/d) and hydroxychloroquine sulfate (5 mg/kg/d) (control group) or prednisone (0.5 mg/kg/d) and hydroxychloroquine sulfate (5 mg/kg/d) plus MMF (500 mg twice daily) (MMF group) for 96 weeks. The primary outcome was the proportion of patients presenting with flares according to the Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) Flare Index. The secondary outcomes included the proportion with lupus low disease activity state at week 96, 36-Item Short Form Health Survey scores before and after treatment, proportion of adverse events (AEs), and changes in SLEDAI-2000 scores and prednisone doses. Among 130 randomized patients (mean [SD] age, 34.5 [12.5] years; 112 [86.2%] women), 119 (91.5%) completed the follow-up. The risk of severe flare was significantly lower in the MMF group (7 of 65 [10.8%]) vs the control group (18 of 65 [27.7%]) (relative risk [RR], 0.39 [95% CI, 0.17-0.87]; P = .01). Additionally, 1 of 65 patients in the MMF group (1.5%) and 9 of 65 in the control group (13.8%) manifested LN (RR, 0.11 [95% CI, 0.01-0.85]; P = .008). Most common serious study drug-related AEs were infections (20 of 65 [30.8%] in the control group and 22 of 65 [33.8%] in the MMF group). The findings of this randomized clinical trial suggest that MMF may reduce the rate of severe flare and lower the incidence of LN in patients with new-onset SLE and a high titer of anti-dsDNA antibody without major organ involvement.

Characterisation and outcomes of different subsets of low disease activity states in patients with systemic lupus erythematosus

ObjectivesThe lupus low disease activity state (LLDAS) allows for certain clinical and/or serological activity of SLE, provided overall disease activity does not exceed predefined cut-offs. This study aimed to evaluate...

The implication of anti-Ro60 with or without anti-Ro52 antibody in patients with systemic lupus erythematosus.

Anti-Ro60 and anti-Ro52 autoantibodies are frequently used as diagnostic biomarkers for Sjogren's disease, but their clinical significance in systemic lupus erythematosus (SLE) is not well characterised. Patients fulfilling SLE classification criteria were studied according to their anti-Ro status. We defined Ro positivity (Ro+) as those who have either anti-Ro60 or anti-Ro52 positivity. Patient characteristics and disease outcomes, including High Disease Activity Status (HDAS) defined as an ever attainment of SLEDAI2K ≥10, adjusted mean SLEDAI (AMS), and time-adjusted mean clinical SLEDAI (excluding serologic activities) were compared using linear or logistic regressions. Furthermore, isolated or dual positivity of anti-Ro60 and anti-Ro52 were studied. Out of 409 patients, 47.2% were Ro+. Ro+ patients were predominantly Asian, had positive dsDNA and hypocomplementemia. They showed a higher likelihood of HDAS (OR 1.65, 95% CI 1.10-2.48, p= 0.015), AMS > 4 (OR 1.84, 1.18-2.88, p= 0.007), and more frequent use of glucocorticoids (OR 1.87, 1.16-3.03, p= 0.011) and immunosuppressants (OR 2.0, 1.26-3.17, p= 0.003). Additionally, 24.4% of Ro+ patients experienced sicca symptoms, and hypergammaglobulinemia was significantly more common. Multivariate analysis confirmed that Asian ethnicity, severe flares, AMS, hypocomplementemia, rheumatoid factor, proteinuria, leucopenia, and sicca symptoms were significantly linked to Ro positivity. Anti-Ro positivity is associated with higher disease activity and increased treatment needs. Ro positivity correlates with laboratory abnormalities such as hypocomplementemia and leucopenia. These findings highlight the importance of anti-Ro60/Ro52 testing in the clinical evaluation of SLE.

Improved Health Outcomes in Patients with Systemic Lupus Erythematosus Following Early Belimumab Initiation Without Prior Immunosuppressant Use: A Real-World Descriptive Study.

Patients with systemic lupus erythematosus (SLE) have variable treatment pathways, including antimalarials, glucocorticoids, immunosuppressants, and/or biologics. This study describes differences in clinical outcomes when initiating belimumab (BEL) before and after immunosuppressant use. This real-world, retrospective cohort study (GSK Study 217536) used de-identified administrative claims data from January 2015 to December 2022 in the Komodo Health Database. Adults with moderate/severe SLE initiating BEL (index date) were identified from January 2017 to May2022, allowing a ≥ 24-month baseline period. Patients were stratified into those initiating BEL before immunosuppressant use (no immunosuppressant use within 24months before index) and those initiating BEL after immunosuppressant use (one immunosuppressant used within 24months before index). Oral glucocorticoid (OGC) use, SLE flares, new organ damage, and all-cause healthcare resource utilization (HCRU) were analyzed descriptively over a 24-month follow-up. Baseline SLE severity was similar for patients initiating BEL before (n = 2295) versus after (n = 4114) immunosuppressant use (moderate, 83.1% vs 79.0%; severe, 16.8% vs 21.0%). Patients initiating BEL before versus after immunosuppressant use had lower SLE flare rates and OGC use. Post-index, patients initiating BEL before versus after immunosuppressant use discontinued their OGC sooner (moderate baseline SLE, 4.5 vs 8.9months; severe baseline SLE, 6.2 vs 11.6months). Patients initiating BEL before versus after immunosuppressant use had lower SLE flare rates per person-year at all time points (especially severe flare rates in patients with severe baseline SLE, 0.70 vs 1.48 through 24months post-index). Median time to new organ damage occurrence was longer in patients initiating BEL before versus after immunosuppressant use (moderate baseline SLE, 32.1 vs 26.7months; severe baseline SLE, 22.7 vs 21.6months). All-cause HCRU was similar between cohorts. These results suggest that patients initiating BEL before versus after immunosuppressant use had more favorable outcomes.

Phenotypic subgroup in serologically active clinically quiescent systemic lupus erythematosus: A cluster analysis based on CSTAR cohort

Serologically active clinically quiescent (SACQ) is a state within systemic lupus erythematosus (SLE) characterized by elevated serologic markers without clinical activity. The heterogeneity in SACQ patients poses challenges in disease management. This multicenter prospective study aimed to identify distinct SACQ subgroups and assess their utility in predicting organ damage. SACQ was defined as a sustained period of at least 6months with persistent serologic activity, marked by positive anti-double-stranded DNA (dsDNA) antibodies and/or hypocomplementemia, and without clinical activity. Cluster analysis was employed, utilizing 16 independent components to delineate phenotypes. Among the 4,107 patients with SLE, 990 (24.1%) achieved SACQ within 2.0± 2.3 years on average. Over a total follow-up of 7,105.1 patient years, 340 (34.3%) experienced flares, and 134 (13.5%) developed organ damage. Three distinct SACQ subgroups were identified. Cluster 1 (n= 219, 22.1%) consisted predominantly of elderly males with a history of major organ involvement at SLE diagnosis, showing the highest risk of severe flares (16.4%) and organ damage (27.9%). Cluster 2 (n= 279, 28.2%) was characterized by milder disease and a lower risk of damage accrual (5.7%). Notably, 86 patients (30.8%) in cluster 2 successfully discontinued low-dose glucocorticoids, with 49 of them doing so without experiencing flares. Cluster 3 (n= 492, 49.7%) featured the highest proportion of lupus nephritis and a moderate risk of organ damage (11.8%), with male patients showing significantly higher risk of damage (hazard ratio [HR]= 4.51, 95% confidence interval [CI], 1.82-11.79). This study identified three distinct SACQ clusters, each with specific prognostic implications. This classification could enhance personalized management for SACQ patients. This work was funded by the National Key R&D Program (2021YFC2501300), the Beijing Municipal Science& Technology Commission (Z201100005520023), the CAMS Innovation Fund (2021-I2M-1-005), and National High-Level Hospital Clinical Research Funding (2022-PUMCH-D-009).

Clinical disease activity in autoimmune rheumatic patients receiving COVID-19 vaccines

BackgroundVaccines are a crucial component of the global efforts to control the spread of COVID-19. Very little is known about COVID-19 vaccine responses in patients living with autoimmune rheumatic conditions in Africa. We examined the clinical reaction to COVID-19 vaccinations in Ghanaians diagnosed with autoimmune rheumatic disease.MethodsThis was a hospital-based interventional cohort study of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) patients recruited via regular face-to-face clinic visits. The systemic lupus erythematosus disease activity index Selena modification (SELENA-SLEDAI) and the disease activity score 28-joint count-erythrocyte sedimentation rate (DAS28-ESR) were used to measure changes in disease activity levels.ResultsThirty-eight (38) patients of which 21 (55.3%) were diagnosed with SLE and 17 (44.7%) with RA contributed data for analyses. Most (89.5%) of the patients were females, with a mean age of 37.4 years. The SLE patients experienced a notable increase in severe flares during weeks three and six, as well as the third and sixth months, followed by subsequent decreases in the twelfth month, while remission levels increased throughout the same period. Among RA patients, high disease activity decreased during weeks three and six, as well as the third, sixth, and twelfth months, with remission levels increasing during the same time. A low dose (≥ 50 < 75 mg) dose of azathioprine was at some point associated with having a severe flare among SLE patients. After both vaccine doses, SLE patients were the majority having experienced both local and systemic reactions, all resolving within 24 h. Approximately 73.7% of the patients were COVID-19 negative at baseline. During post-vaccination visits, this increased to 100% by week six, with no positives thereafter.ConclusionThis study explores COVID-19 vaccine responses in Ghanaian autoimmune rheumatic disease patients, revealing disease activity levels in RA patients improved after vaccination compared to SLE patients. Our findings identify a potential link between low-dose azathioprine and severe flares in SLE patients, particularly evident in the third-week post-vaccination. Further research is warranted to clarify these findings and guide tailored treatment approaches in this medically significant population during pandemics and vaccination efforts.

Sustained depression of B cell counts in lupus nephritis after treatment with rituximab and/or belimumab is associated with fewer disease flares.

To study the risk of lupus nephritis flare (LNF) or severe lupus flare (SLF) as a function of B cell count kinetics in lupus nephritis (LN) patients after they achieve at least a partial renal response (PRR) with induction treatment that includes rituximab (RTX) and/or belimumab (BLM). We performed a retrospective analysis of a cohort of 19 patients with severe LN that received a B cell agent (BCA), RTX and/or BLM, as part of an initial treatment regimen for an LN flare and had subsequent CD19+ B cell measurements in peripheral blood. We then characterized the follow-up periods, after B cell depressions occurred and PRR were achieved, by the corresponding trajectories of B cell counts (BCC). Time periods with sustained low BCC were type 1 (T1) episodes, while those with repletion of BCC>100 cells/μL were called type 2 (T2) episodes. Time periods with rapid BCC repletion, defined as >50 cells/μL in ≤6months, were called T2b episodes. Corresponding C3, C4, and anti-dsDNA levels were recorded for each episode. The time from PRR until an event, either a LNF or SLF, or to censoring, either at the end of the study period or the end of available patient follow-up, was assessed for each episode type. Kaplan-Meier survival analysis was used to compare time to flare between T1 and T2 episodes. There were 26 episodes of B cell depression. Seventeen (65%) were T1 and 9 (35%) were T2. Compared to T1 episodes, T2 episodes were 9.0 times more likely to result in flare over the follow-up period (hazard ratio (HR) = 9.0, 95% CI for HR = 2.2-36.7); this risk was even larger for T2b vs T1 episodes. Median BCC was 14 cells/μL in T1 and 160 cells/μL in T2 episodes. Both C3 and C4 levels significantly increased over the duration of the episode in T1 episodes only. Sustained low BCC was associated with prolonged serologic and clinical response, whereas repletion, and particularly rapid repletion, of B cells after treatment with BCA was associated with subsequent disease flare.

Hydroxychloroquine levels in pregnancy and materno-fetal outcomes in Systemic Lupus Erythematosus patients.

Data about hydroxychloroquine (HCQ) levels during pregnancy are sparse. We assessed HCQ whole blood levels at first trimester of pregnancy as a potential predictor of maternal and obstetric/fetal outcomes in patients with systemic lupus erythematosus (SLE). We included pregnant SLE patients enrolled in the prospective GR2 study receiving HCQ, with at least one available first-trimester whole-blood HCQ assay. We evaluated several cut-offs for HCQ whole blood levels, including ≤200 ng/ml for severe non-adherence. Primary outcomes were maternal flares during the second and third trimesters of pregnancy, and adverse pregnancy outcomes (APOs: fetal/neonatal death, placental insufficiency with preterm delivery, and small-for-gestational-age neonates). We included 174 patients (median age: 32.1 years, IQR 28.8-35.2). Thirty (17.2%) patients had flares, 4 (2.3%) being severe. APOs occurred in 28 patients (16.1%). There were no significant differences in APOs by HCQ level for either those with subtherapeutic HCQ levels (≤500 ng/ml vs >500 ng/ml: 23.5% vs 14.3%, p = 0.19) or those with non-adherent HCQ levels (≤200 ng/ml vs >200 ng/ml: 20.0% vs 15.7%, p = 0.71). Similarly, the overall rate of maternal flares did not differ significantly by HCQ level cut-off, but patients with subtherapeutic (HCQ ≤500 ng/ml: 8.8% vs 0.7%, p = 0.02) and non-adherent HCQ levels (≤200 ng/ml: 13.3% vs 1.3%, p = 0.04) had significantly more severe flares. In this large prospective study of pregnant SLE patients, first-trimester subtherapeutic (≤500 ng/ml) and severe non-adherent (≤200 ng/ml) HCQ levels were associated with severe maternal flares, but not with APOs.

Inpatient Management of Hidradenitis Suppurativa: A Delphi Consensus Study.

Inpatient hospitalization of individuals with hidradenitis suppurativa (HS) has increased. Inpatient services may not be familiar enough with this disease to understand how to manage severe HS and/or HS flares. It would be beneficial to the inpatient medical community to establish consensus recommendations on holistic inpatient care of patients with HS. A survey study was developed and distributed by Wake Forest University School of Medicine (Winston-Salem, North Carolina). A total of 26 dermatologists participated in the Delphi process, and the process was conducted in 2 rounds. Participants voted on proposal statements using a 9-point scale (1=very inappropriate; 9=very appropriate). Statements were developed using current published guidelines for management of HS and supportive care guidelines for other severe inpatient dermatologic diseases. A total of 50 statements were reviewed and voted on between the 2 rounds. Consensus was determined using the RAND/UCLA Appropriateness Method. Twenty-six dermatologists completed the first-round survey, and 24 completed the second-round survey. The 40 consensus recommendations generated through these surveys can serve as a resource for providers caring for inpatients with HS.

Healthcare resource utilization and costs in patients with a newly confirmed diagnosis of lupus nephritis in the United States over a 5-year follow-up period

BackgroundWe aimed to describe healthcare resource utilization (HCRU) and healthcare costs in patients with newly confirmed lupus nephritis (LN) in the United States over a 5-year follow-up period.MethodsThis retrospective, longitudinal cohort study (GSK Study 214102) utilized administrative claims data to identify individuals with a newly confirmed diagnosis of LN between August 01, 2011, and July 31, 2018, based on LN-specific International Classification of Diseases diagnosis codes. Index was the date of first LN-related diagnosis code claim. HCRU, healthcare costs, and incidence of systemic lupus erythematosus (SLE) flares were reported annually among eligible patients with at least 5 years continuous enrollment post-index.ResultsOf 2,159 patients with a newly confirmed diagnosis of LN meeting inclusion and exclusion criteria, 335 had at least 5 years continuous enrollment post-index. HCRU was greatest in the first year post-LN diagnosis across all categories (inpatient admission, emergency room [ER] visits, ambulatory visits, and pharmacy use), and trended lower, though remained substantial, in the 5-year follow-up period. Among patients with LN and HCRU, the mean (standard deviation [SD]) number of ER visits and inpatient admissions were 3.7 (4.6) and 1.8 (1.5), respectively, in Year 1, which generally remained stable in Years 2–5; the mean (SD) number of ambulatory visits and pharmacy fills were 35.8 (25.1) and 62.9 (43.8), respectively, in Year 1, and remained similar for Years 2–5. Most patients (≥ 91.6%) had ≥ 1 SLE flare in each of the 5 years of follow-up. The proportion of patients who experienced a severe SLE flare was higher in Year 1 (31.6%) than subsequent years (14.3–18.5%). Total costs (medical and pharmacy; mean [SD]) were higher in Year 1 ($44,205 [71,532]) than subsequent years ($29,444 [52,310]–$32,222 [58,216]), driven mainly by inpatient admissions (Year 1: $21,181 [58,886]; subsequent years: $7,406 [23,331]–$9,389 [29,283]).ConclusionsPatients with a newly confirmed diagnosis of LN have substantial HCRU and healthcare costs, particularly in the year post-diagnosis, largely driven by inpatient costs. This highlights the need for improved disease management to prevent renal damage, improve patient outcomes, and reduce costs among patients with renal involvement.

Characterization of patients with atopic dermatitis based on flare patterns and severity of disease: A Danish population-based study.

Flare patterns are not routinely considered in the severity classification or in clinical decision-making of atopic dermatitis (AD), but frequent or severe flares may contribute considerably to the disease burden. To characterize patients with AD in relation to their flare pattern and compare flare patterns to disease severity, life quality and treatment satisfaction. Patients with AD from the Danish Skin Cohort were included if they had active AD with and available data on number of flare-ups within the last 12 months. Categorical variables were presented as frequencies and percentages, whereas numerical variables were presented as median and interquartile ranges (IQR). Between-group differences were tested with chi-squared tests. A total of 1557 patients were included, with 57 reporting 0 flares, 698 (1-5 flares), 324 (6-10 flares) and 478 reporting >10 flares during the past 12 months. Both the severity measured by PO-SCORAD and the impairment of life quality measured by DLQI were higher among patients with more flares (median [IQR] PO-SCORAD: 13.0 [5.6-22.3], 29.7 [20.8-40.6], 36.3 [26.7-47.6]and 42.9 [30.7-55.6], respectively for the four flares strata, and median [IQR] DLQI: 1.0 [0.0-2.0], 3.0 [1.0-7.0], 4.0 [1.8-9.0] and 7.0 [3.0-11.0]). Satisfaction with the current treatment was generally higher among patients with no flares. However, 36.8%, 24.6% and 23.7% of patients with 1-5, 6-10 and >10 flares reported being extremely or very satisfied with their current treatment. Patients with many flares often report a higher severity and impairment of life quality compared to patients with fewer flares. Information on flaring could benefit treatment decisions, thereby decreasing undertreatment of patients with mild AD but severe flaring.

Intestinal ultrasound scan predicts corticosteroid failure and colectomy risk in patients with ulcerative colitis.

Intestinal ultrasound (IUS) is an emerging modality for assessing disease activity, extent, and treatment response in ulcerative colitis. This study aimed to evaluate the potential of IUS in predicting severe flares, the need for rescue therapy (corticosteroid failure), and colectomy in patients with ulcerative colitis. We conducted a retrospective review of medical records, collecting clinical and IUS data. The Milan Ultrasound Criteria (MUC) score was used to assess ulcerative colitis severity. Group comparisons were performed to identify differences in MUC scores between mild-to-moderate and severe ulcerative colitis, between steroid responders and nonresponders, and between patients who underwent colectomy and those who did not. Receiver operating characteristic (ROC) analysis was used to predict outcomes in patients with ulcerative colitis. This analysis included 102 patients with ulcerative colitis categorized as mild/moderate (60) or severe (42). MUC scores were significantly higher in the severe ulcerative colitis group compared with the mild/moderate group ( P < 0.001). Analysis (using ROC) identified a cutoff MUC score of >8.54 to indicate severe ulcerative colitis with good sensitivity (64.29%) and excellent specificity (93.33%). Similarly, a cutoff of MUC > 10.54 showed promise in predicting corticosteroid failure, with acceptable sensitivity (50%) and high specificity (90.91%). Finally, a cutoff MUC score >12.5 demonstrated potential for predicting colectomy, exhibiting moderate sensitivity (55.56%) but excellent specificity (96.97%). IUS may be useful for differentiating severe ulcerative colitis from mild-to-moderate disease, identifying early stage failure of corticosteroid therapy, and predicting the potential need for colectomy.

JNJ-73763989 and bersacapavir treatment in nucleos(t)ide analogue-suppressed patients with chronic hepatitis B: REEF-2

Functional cure for chronic hepatitis B (CHB) requires finite treatment. Two agents under investigation with the goal of achieving functional cure are the small-interfering RNA JNJ-73763989 (JNJ-3989) and the capsid assembly modulator JNJ-56136379 (JNJ-6379; bersacapavir). REEF-2, a phase IIb, double-blind, placebo-controlled, randomized study, enrolled 130 nucleos(t)ide analogue (NA)-suppressed hepatitis B e-antigen (HBeAg)-negative patients with CHB who received JNJ-3989 (200mg subcutaneously every 4 weeks) + JNJ-6379 (250mg oral daily) + NA (oral daily; active arm) or placebos for JNJ-3989 and JNJ-6379+active NA (control arm) for 48 weeks followed by 48 weeks off-treatment follow-up. At follow-up Week 24, no patients achieved the primary endpoint of functional cure (off-treatment hepatitis B surface antigen [HBsAg] seroclearance). No patients achieved functional cure at follow-up Week 48. There was a pronounced on-treatment reduction in mean HBsAg from baseline at Week 48 in the active arm vs. no decline in the control arm (1.89 vs. 0.06 log10IU/ml; p= 0.001). At follow-up Week 48, reductions from baseline were >1 log10IU/ml in 81.5% vs. 12.5% of patients in the active and control arms, respectively, and 38/81 (46.9%) patients in the active arm achieved HBsAg <100IU/ml vs. 6/40 (15.0%) patients in the control arm. Off-treatment HBV DNA relapse and alanine aminotransferase increases were less frequent in the active arm, with 7/77 (9.1%) and 11/41 (26.8%) patients in the active and control arms, respectively, restarting NAs during follow-up. Finite 48-week treatment with JNJ-3989 + JNJ-6379 + NA resulted in fewer and less severe post-treatment HBV DNA increases and alanine aminotransferase flares, and a higher proportion of patients with off-treatment HBV DNA suppression, with or without HBsAg suppression, but did not result in functional cure. Achieving a functional cure from chronic hepatitis B (CHB) with finite treatments is a major unmet medical need. The current study assessed the rate of functional cure and clinical outcome after controlled nucleos(t)ide analogue (NA) withdrawal in patients with low levels of HBsAg induced by 48 weeks of treatment with the small-interfering RNA JNJ-3989 and the capsid assembly modulator JNJ-6379 plus NA vs. patients who only received NA treatment. Though functional cure was not achieved by any patient in either arm, the 48-week treatment regimen of JNJ-3989, JNJ-6379, and NA did result in more patients achieving pronounced reductions in HBsAg, with clinically meaningful reductions maintained for up to 48 weeks off all treatments, as well as fewer off-treatment HBV DNA increases and alanine aminotransferase flares. These findings provide valuable insights for future studies investigating potential finite treatment options, while the reported efficacy and safety outcomes may be of interest to healthcare providers making treatment decisions for patients with NA-suppressed HBeAg-negative CHB.

ALT to qHBsAg ratio predicts long-term HBsAg seroclearance after entecavir cessation in Chinese patients with chronic hepatitis B

Factors predicting HBsAg seroclearance after treatment cessation, irrespective of nucleos(t)ide analogue (NA) resumption, have important clinical implications. We evaluated predictors of long-term HBsAg seroclearance after entecavir cessation. This study followed-up Chinese patients with chronic hepatitis B from two previous studies of entecavir cessation. All patients were non-cirrhotic, HBeAg-negative, with undetectable HBV DNA (<20IU/ml) at end-of-treatment (EOT). They were monitored closely for 48 weeks with regular HBV DNA, quantitative HBsAg (qHBsAg) and alanine aminotransferase (ALT) measurements. Entecavir was resumed at HBV DNA >2,000IU/ml, irrespective of ALT levels. After the initial 48 weeks, patients were assessed every 6 months, regardless of entecavir resumption, to monitor for HBsAg seroclearance. A total of 194 patients (63.4% male, mean age 49.9 years, on entecavir for a median of 47.2 months) were recruited; 94 (48.5%) and 158 (81.4%) patients had EOT qHBsAg <100IU/ml and <1,000IU/ml, respectively; 151 (77.8%) patients were eventually resumed on entecavir. After follow-up for a median of 70.7 (51.0-118.2) months, 28 (14.4%) patients had HBsAg seroclearance. qHBsAg levels at weeks 36 and 48 after EOT independently predicted HBsAg seroclearance (both p<0.01), whereas qHBsAg from EOT to week 24 only trended towards statistical significance. The ratio of ALT/qHBsAg at all time points from EOT to week 48 independently predicted HBsAg seroclearance (hazard ratios ranging from 1.003-1.028, all p<0.01) with excellent diagnostic performance (area under the receiver-operating characteristic curve 0.799-0.933, negative predictive value >90% at different time points), regardless of whether entecavir was resumed. The ALT/qHBsAg ratio after entecavir cessation predicts HBsAg seroclearance, even in patients who were resumed on treatment. Its use may mitigate the risk of severe hepatitis flares in patients managed by observation without treatment resumption. Current predictors of HBsAg seroclearance after finite nucleos(t)ide analogue (NA) therapy have suboptimal predictive value. We demonstrated that the ALT/qHBsAg ratio may be able to reflect the balance between host control and virological activity. The ALT/qHBsAg ratio at different time points from end-of-treatment till week 48 independently and accurately predicted HBsAg seroclearance in patients who have stopped entecavir. The ALT/qHBsAg ratio may be utilized by clinicians for patient selection and retreatment decisions in finite NA therapy.
