Effect of Corticosteroid on Immunogenicity of SARS-CoV-2 Vaccines in Patients With Solid Cancer.

Corticosteroids are known to diminish immune response ability, which is generally used in routine premedication for chemotherapy. The intersecting of timeframe between the corticosteroid's duration of action and peak COVID-19 vaccine efficacy could impair vaccine immunogenicity. Thus, inquiring about corticosteroids affecting the efficacy of vaccines to promote effective immunity in this population is needed. This was a prospective longitudinal observational cohort study that enrolled patients with solid cancer classified into dexamethasone- and nondexamethasone-receiving groups. All participants were immunized with two doses of ChAdOx1 nCoV-19 or CoronaVac vaccines. This study's purpose was to compare corticosteroid's effect on immunogenicity responses to the SARS-CoV-2 S protein in patients with cancer after two doses of COVID-19 vaccine in the dexamethasone and nondexamethasone group. Secondary outcomes included the postimmunization anti-spike (S) immunoglobin G (IgG) seroconversion rate, the association of corticosteroid dosage, time duration, and immunogenicity level. Among the 161 enrolled patients with solid cancer, 71 and 90 were in the dexamethasone and nondexamethasone groups, respectively. The median anti-S IgG titer after COVID-19 vaccination in the dexamethasone group was lower than that in the nondexamethasone group with a statistically significant difference (47.22 v 141.09 U/mL, P = .035). The anti-S IgG seroconversion rate was also significantly lower in the dexamethasone group than in the nondexamethasone group (93.83% v 80.95%, P = .023). The lowest median anti-SARS-CoV-2 IgG titer level at 7.89 AU/mL was observed in patients with the highest dose of steroid group (≥37 mg of dexamethasone cumulative dose throughout the course of chemotherapy [per course]) and patients who were injected with COVID-19 vaccines on the same day of receiving dexamethasone, 25.41 AU/mL. Patients with solid cancer vaccinated against COVID-19 disease while receiving dexamethasone had lower immunogenicity responses than those who got vaccines without dexamethasone. The direct association between the immunogenicity level and steroid dosage, as well as length of duration from vaccination to dexamethasone, was observed.

Risankizumab as a Therapeutic Approach for Recalcitrant Pyoderma Gangrenosum.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis that is challenging to diagnose and treat. Clinicians frequently use fast-acting corticosteroids, which are subsequently combined with slower-acting immunosuppressants to progressively taper the corticosteroid dosage. Current research is focused on the use of monoclonal antibodies (mAbs) directed against target molecules involved in the pathogenesis of PG. However, available data on their efficacy are based on sporadic case reports and clinical experiences, so the authors aimed to evaluate the efficacy of risankizumab, an anti-interleukin-23 mAb, in the management of two complex PG cases. The authors enrolled two patients with PG who were already treated with immunosuppressive therapies. Their management was based on the off-label use of an mAb directed against the p19 subunit of interleukin-23: risankizumab. Patients received subcutaneous injections of 150 mg at the start of treatment, at week 4, and then every 10 weeks thereafter. Systemic therapy was combined with local management of ulcers, based on the principles of TIME (tissue, infection, moisture balance, and epithelialization) applied to the inflammatory and noninflammatory phases of PG. Clinical resolution was obtained at week 24 for patient 1 and week 16 for patient 2 and was maintained until week 40, without adverse effects or disease recurrence. These clinical cases demonstrate that risankizumab is a valid tool in terms of efficacy and safety for complicated cases of multirefractory PG when provided in parallel with local personalized wound management.

Corticosteroid Injections and Risk of Fracture

Corticosteroid injections (CSIs) are an important tool for pain relief in many musculoskeletal conditions, but the longitudinal effects of these treatments on bone health and fracture risk are unknown. To determine whether cumulative doses of corticosteroid injections are associated with higher risk of subsequent osteoporotic and nonosteoporotic fractures. This cohort study included adult patients receiving any CSI from May 1, 2018, through July 1, 2022. Eligible patients resided in Olmsted County, Minnesota, and were empaneled to receive primary care within the Mayo Clinic. Cox proportional hazards regression models were used to evaluate risk of fracture based on cumulative injected corticosteroid dose. Receipt of any CSI during the study period. The primary outcome was risk of fracture by total triamcinolone equivalents received. Secondary outcomes consisted of risks of fracture based on triamcinolone equivalents received in subgroups of patients not at high risk for fracture and patients with osteoporosis. A total of 7197 patients were included in the study (mean [SD] age, 64.4 [14.6] years; 4435 [61.6%] women; 183 [2.5%] Black and 6667 [92.6%] White), and 346 (4.8%) had a new fracture during the study period. Of these fractures, 149 (43.1%) were considered osteoporotic. In the adjusted Cox proportional hazards regression model, there was no association of higher fracture risk based on cumulative CSI dose (adjusted hazard ratio [HR], 1.04 [95% CI, 0.96-1.11]). There was also no associated higher risk of fracture in the non-high-risk (adjusted HR, 1.11 [95% CI, 0.98-1.26]) or osteoporosis (adjusted HR, 1.01 [95% CI, 0.90-1.11]) subgroups. Age, Charleson Comorbidity Index, and previous fracture were the only factors that were associated with higher fracture risk. In this cohort study of cumulative injected corticosteroid dose and risk of subsequent fracture, no association was observed, including in patients with a preexisting diagnosis of osteoporosis. Treatment of painful conditions with CSI should not be withheld or delayed owing to concern about fracture risk.

Management of Select Adverse Events Following Delandistrogene Moxeparvovec Gene Therapy for Patients With Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is a rare, degenerative, recessive X-linked neuromuscular disease. Mutations in the gene encoding dystrophin lead to the absence of functional dystrophin protein. Individuals living with DMD exhibit progressive muscle weakness resulting in loss of ambulation and limb function, respiratory insufficiency, and cardiomyopathy, with multiorgan involvement. Adeno-associated virus vector-mediated gene therapy designed to enable production of functional dystrophin protein is a new therapeutic strategy. Delandistrogene moxeparvovec (Sarepta Therapeutics, Cambridge, MA) is indicated for treatment of ambulatory pediatric patients aged 4 through 5 years with DMD who have an indicated mutation in the DMD gene. Evidence-based considerations for management of potential adverse events following gene therapy treatment for DMD are lacking in clinical literature. Our goal was to provide interdisciplinary consensus considerations for selected treatment-related adverse events (TRAEs) (vomiting, acute liver injury, myocarditis, and immune-mediated myositis) that may arise following gene therapy dosing with delandistrogene moxeparvovec. An interdisciplinary panel of 12 specialists utilized a modified Delphi process to develop consensus considerations for the evaluation and management of TRAEs reported in delandistrogene moxeparvovec clinical studies. Panelists completed 2 Questionnaires prior to gathering for an in-person discussion. Consensus was defined as a majority (≥58% ; 7/12) of panelists either agreeing or disagreeing. Panelists agreed that the choice of baseline assessments should be informed by individual clinical indications, the treating provider's judgment, and prescribing information. Corticosteroid dosing for treatment of TRAEs should be optimized by considering individual risk versus benefit for each indication. In all cases involving patients with a confirmed TRAE, consultations with appropriate specialists were suggested. The Delphi Panel established consensus considerations for the evaluation and management of potential TRAEs for patients receiving delandistrogene moxeparvovec, including vomiting, acute liver injury, myocarditis, and immune-mediated myositis.

Adalimumab for the Treatment of Non-Infectious Uveitis: A Real Life Experience

ABSTRACT Objective To describe the efficacy and safety of adalimumab for the treatment of non-infectious uveitis (NIU) in four Uveitis Units from tertiary Spanish hospitals. Methods Multicenter and retrospective clinical cohort study including all patients with NIU treated with adalimumab from January 2012 to October 2022 in four uveitis units was performed. Efficacy was measured with the number of relapses, ocular inflammation and reduction in immunosuppression and corticosteroid dosage before and after adalimumab use. We collected data regarding adverse effects and examined the immunogenicity of adalimumab. Results One hundred and twenty-two patients (59% females), with a mean age of 48.6 years (SD = 14.8) accounting for 217 eyes were included. The majority (92.6%) were Caucasian. Uveitis analyzed were predominantly panuveitis (34.7%), bilateral (77.9%), acute (41.5%), and non-granulomatous (90%). Most of them were immune mediated (42.6%), and the main reason to initiate adalimumab was refractory disease (96.7%). The analysis was statistically significant due to the reduction in the number of immunosuppressive drugs as well as the dose of oral corticosteroids and the number of relapses during follow-up (p < 0.001). The decrease in ocular inflammation parameters and the improvement in visual acuity (p < 0.05) were also significant. There were no deaths due to the drug and only one reported case of serious infection. In total, 10.9% of 73 patients tested developed anti-adalimumab antibodies and 4.1% lupus-like. Conclusions We consider adalimumab as a leading drug in the treatment of NIU with high safety and efficacy.

P043 The different roles of FRAX risk factors as predictors of fragility fractures in peri-menopausal vs post-menopausal patients: results from a large population-based cohort study

Abstract Background/Aims The marked rise in the prevalence of fragility fractures affecting both women undergoing the transition to menopause (i.e. peri-menopause), and post-menopausal women, confers a significant burden on patients’ health and quality of life. The risk factors for fractures in post-menopausal women have been previously well-explored, and tend to align with the FRAX variables. However, there is less consensus regarding the fracture risk factors in peri-menopausal women. We compare the association between FRAX risk factors and fractures across peri-menopausal and post-menopausal women, selected from the same large population-based cohort. Methods Female patients referred for a DXA scan at the Royal Lancaster Infirmary between 2004-2011 provided information relating to any previous fragility fracture(s), FRAX risk factors, and menopause status (i.e. not post-menopausal vs post-menopausal) through a questionnaire. Patients aged 41 to 51 (median menopause age in UK) who had not undergone the menopause, as per their questionnaire response, were categorised as ‘peri-menopausal’. Logistic regression modelling, which included adjustment for potential confounders, was performed using r(version 4.3.1). Results Our study included 23388 patients, including 3785 peri-menopausal patients and 20774 post-menopausal patients, with a mean age of 47.5 (SD:3.0) and 66.1 (SD:10.4) respectively. The prevalence of fragility fractures was greater in the post-menopausal than peri-menopausal cohort (42.8% vs 25.5% respectively; p &amp;lt; 0.001). Across post-menopausal patients, following adjustment for the other FRAX risk factors, significant predictors of increased fracture risk were age (odds ratio (OR): 1.04 (95% CI:1.03-1.04, p &amp;lt; 0.001), smoking (OR:1.16 (CI:1.09-1.23, p &amp;lt; 0.001), alcohol (OR:1.54, CI:1.36-1.74, p &amp;lt; 0.001), and a family history of fracture(s) (OR:1.21 (CI:1.13-1.29, p &amp;lt; 0.001). Comparatively, across peri-menopausal patients, only alcohol (OR:1.57, CI:1.08-2.26, p = 0.016) and smoking (OR:1.22 (CI:1.00-1.48, p = 0.045) positively predicted fracture risk. Corticosteroid use was associated with a reduced fracture risk across both post-menopausal (OR:0.84, CI:0.79-0.90, p &amp;lt; 0.001) and peri-menopausal (OR:0.79, CI: 0.64-0.97, p = 0.024) cohorts. Conclusion Different FRAX risk factors predict fracture occurrence across post-menopausal and peri-menopausal patients; notably, only smoking and alcohol consumption predict an increased fracture risk in the latter group. Interestingly, corticosteroids were associated with a reduced risk of fractures across both groups. This finding may be elucidated by the fact that low-dose corticosteroids can exert an anti-inflammatory effect, and may protect bone cells. However, our finding is limited by the fact that the indication, dose and duration of corticosteroids were unknown. More generally, our study is limited by the fact that patients’ peri-menopausal status was not clinically confirmed, but inferred based on patients’ age and self-reported menopause status. Our results suggest that the FRAX risk factors, which were derived from analysis of predominantly 50-80 year old patients, may require adjustment for peri-menopausal patients (many of whom are aged &amp;lt;50). Future studies should assess whether our conclusions apply to specific fracture sites, and are replicated across more demographically diverse patient populations. Disclosure K. Song: None. M.

Growth after pediatric kidney transplantation: a 25-year study in a pediatric kidney transplant center.

Growth failure is one of the major complications of pediatric chronic kidney disease. Even after a kidney transplant (KT), up to 50 % of patients fail to achieve the expected final height. This study aimed to assess longitudinal growth after KT and identify factors influencing it. A retrospective observational study was performed. We reviewed the clinical records of all patients who underwent KT for 25 years in a single center (n=149) and performed telephone interviews. Height-for-age and body mass index (BMI)-for-age were examined at KT, 3months, 6months, 1 year, and 5 years post-transplant and at the transition to adult care. We evaluated target height, disease duration before KT, need and type of dialysis, recombinant human growth hormone pretransplant use, nutritional support, glomerular filtration rate (GFR), and cumulative corticosteroid dose. At transplant, the average height z-score was-1.38, and height z-scores showed catch-up growth at 6months (z-score-1.26, p=0.006), 1 year (z-score-1.15, p<0.001), 5 years after KT (z-score-1.08, p<0.001), and on transition to adult care (z-score-1.22, p=0.012). Regarding BMI z-scores, a significant increase was also detected at all time points (p<0.001). After KT, GFR was significantly associated with height z-score (p=0.006) and BMI z-score (p=0.006). The height in transition to adult care was-1.28 SD compared to the target height. Despite the encouraging results regarding catch-up growth after KT in this cohort, results remain far from optimum, with a lower-than-expected height at the time of transition.

Population Pharmacokinetic Modeling and Exposure-Efficacy and Body Weight-Response Analyses for Tezepelumab in Patients With Severe, Uncontrolled Asthma.

Tezepelumab is a human monoclonal antibody that blocks the activity of thymic stromal lymphopoietin. This analysis assessed the suitability of a fixed-dose regimen of tezepelumab 210 mg every 4 weeks (Q4W) in adults and adolescents with severe, uncontrolled asthma. A population pharmacokinetic model was developed using data from 1368 patients with asthma or healthy participants enrolled in 8 clinical studies (phases 1-3). Tezepelumab exposure-efficacy relationships were analyzed in the phase 3 NAVIGATOR study (NCT03347279), using asthma exacerbation rates over 52 weeks and changes in pre-bronchodilator forced expiratory volume in 1 s at week 52. Tezepelumab pharmacokinetics were well characterized by a 2-compartment linear disposition model with first-order absorption and elimination following subcutaneous and intravenous administration at 2.1-420 and 210-700 mg, respectively. There were no clinically relevant effects on tezepelumab pharmacokinetics from age (≥12 years), sex, race/ethnicity, renal or hepatic function, disease severity (inhaled corticosteroid dose level), concomitant asthma medication use, smoking history, or anti-drug antibodies. Body weight was the most influential covariate on tezepelumab exposure, but no meaningful differences in efficacy or safety were observed across body weight quartiles in patients with asthma who received tezepelumab 210 mg subcutaneously Q4W. There was no apparent relationship between tezepelumab exposure and efficacy at this dose regimen, suggesting that it is on the plateau of the exposure-response curve of tezepelumab. In conclusion, a fixed-dose regimen of tezepelumab 210 mg subcutaneously Q4W is appropriate for eligible adults and adolescents with severe, uncontrolled asthma.

Risk of cardiovascular events following COVID-19 in people with and without pre-existing chronic respiratory disease

Abstract Background COVID-19 is associated with cardiovascular outcomes in the general population, but it is unknown whether people with chronic respiratory disease (CRD) have a higher risk of cardiovascular events post-COVID-19 compared with the general population and, if so, what respiratory-related factors may modify this risk in these people. Methods Primary and secondary care data from the National Health Service England were used to define a population of adults in England with COVID-19 (index date) between 1 January 2020 and 30 November 2021. Adjusted Cox proportional hazard regression was used to quantify the association between CRD, asthma-related factors, chronic obstructive pulmonary disease (COPD)-related factors, and risk of cardiovascular events. Asthma-specific factors included baseline asthma control, exacerbations, and inhaled corticosteroid (ICS) dose. COPD-specific risk factors included baseline ICS and exacerbations. Secondary objectives quantified the impact of COVID-19 hospitalisation and vaccine dose on cardiovascular outcomes. Results Of 3 670 455 people, those with CRD had a higher risk of cardiovascular events [adjusted hazard ratio (HRadj), 1.08; 95% confidence interval (CI) 1.06–1.11], heart failure (HRadj, 1.17; 95% CI, 1.12–1.22), angina (HRadj, 1.13; 95% CI, 1.06–1.20) and pulmonary emboli (HRadj, 1.24; 95% CI, 1.15–1.33) compared with people without CRD. In people with asthma or COPD, baseline exacerbations were associated with a higher risk of cardiovascular outcomes (HRadj, 1.36; 95% CI, 1.27–1.00 and HRadj, 1.35; 95% CI, 1.24–1.46, respectively). Regardless of CRD, the risk of cardiovascular events was lower with increasing COVID-19 vaccine dose. Conclusions Higher risk of cardiovascular events post-COVID-19 might be explained by the underlying severity of the CRD, and COVID-19 vaccines were beneficial to both people with and those without CRD with regards to cardiovascualr events.

Long-Term Effectiveness of Anti-IL-4R Therapy Following Suboptimal Response to Anti-IL-5/5R Therapy in Severe Eosinophilic Asthma

Dupilumab is an anti-IL-4R monoclonal antibody (mAb) with proven efficacy in severe eosinophilic asthma (SEA). A suboptimal response to anti-IL-5/5R mAbs is seen in some patients with ongoing evidence of type 2 (T2) inflammation. To understand whether targeting IL-13 pathways with dupilumab in these patients may lead to better clinical outcomes. We performed a retrospective analysis of the extended clinical effectiveness of dupilumab up to 2 years of treatment in patients with SEA who had not responded adequately to anti-IL-5/5R biologics. The ability to achieve clinical remission and the change in the remission domains of exacerbation rate (AER), maintenance oral corticosteroid dose (mOCS), lung function (forced expiratory volume in 1 second), and asthma control (Asthma Control Questionnaire 6) were recorded. Thirty-seven patients (mean age 41 years, 70% female) were included in the analysis. The mean (standard deviation) AER fell by almost 90% from 3.16 (1.28) at dupilumab initiation to 0.35 (0.72) after 1 year. The median (interquartile range) mOCS dose (n= 20) fell from 10 (5-25) mg to 0 (0-5) mg at 1 year, with 14 of 20 (70%) able to stop prednisolone altogether. Clinical remission was achieved in 16 of 37 (43%). Patients who achieved remission had a higher pre-IL-5/5R fractional exhaled nitric oxide (FeNO) level (85 [39-198] parts per billion [ppb] vs 75 [42-96] ppb, P= .03). Significant improvements in clinical outcomes are possible after a switch to dupilumab in patients experiencing a suboptimal response to anti-IL-5/5R therapies. A higher FeNO in poor responders to anti-IL-5/5R who achieve remission with dupilumab is suggestive of an IL-13-driven subphenotype of T2-high asthma in which the eosinophil appears unlikely to play a key role in the disease pathogenesis.

Tuberculosis miliar en paciente inmunocompetente: Reporte de caso

Milar Tuberculosis (TB) is a presentation with a fatal outcome if it is not diagnosed or treated on time; although certain conditions are required to develop this presentation. In this In this article, the case of a 48-year-old man with no pathological history is studied, who started the disease with a time of six months with an initial diffuse gastrointestinal pain and later one month before admission presented progressive respiratory symptoms; he was admitted for emergencies where bilateral diffuse miliary compromise was evident in the chest computed tomography; upon admission, he was administered oxygen and support measures, an HIV test was obtained which was negative, and positive results were obtained in the sputum smear microscopy. His clinical evolution was stationary until the administration of antituberculosis therapy, observing slight clinical improvement, likewise, low doses of corticosteroids were administered after which a favorable evolution was demonstrated and he was discharged.

Equivalence of single and standard doses of antenatal corticosteroids for late preterm neonatal outcomes: insights from a secondary analysis

BackgroundThe recent paradigm shift of treating individuals at risk of late preterm birth with antenatal corticosteroids warrants an assessment of the effect of single dosage. ObjectiveTo compare outcomes of neonates born in the late preterm period (34.0-36.6 weeks) following a single dose of antenatal corticosteroids versus placebo. Study designWe performed a secondary analysis of the Antenatal Late Preterm Steroids (ALPS) trial (Gyamfi-Bannerman C. et al.). All individuals enrolled in the parent trial who received only a single dose of either antenatal corticosteroids or placebo and delivered within 24 hours were included. Primary outcome was a composite of respiratory support at 72 hr., including continuous positive airway pressure or high flow nasal cannula ≥ 2 h, oxygen with an inspired fraction of ≥ 30% for ≥ 4 h, or mechanical ventilation. ResultsOf the 2,831 individuals in the parent trial, 1,083 (38.3%) met inclusion criteria; of them, 539 (49.8%) received a single dose of antenatal corticosteroids and 544 (50.2%) a single placebo dose. The placebo and antenatal corticosteroids groups had similar demographic and clinical characteristics. There was no difference in the rate of the primary respiratory outcome (aRR 1.12, 95% CI 0.85-1.47) or in the rate of respiratory distress syndrome (aRR 1.47, 95% CI 0.95-2.26) between those who received a single antenatal corticosteroids dose or placebo. An exploratory stratification by randomization-to-delivery intervals of 12-hour increments also showed no association with lower primary respiratory outcome rates. ConclusionIn individuals with late preterm birth pregnancies who received antenatal corticosteroids and delivered before a second dose, there were no differences in neonatal respiratory morbidities compared to placebo.

Efficacy of different doses of corticosteroids in treating severe COVID-19 pneumonia

BackgroundTo investigate the efficacy of different doses of corticosteroids in treating severe coronavirus disease 2019 (COVID-19) pneumonia.MethodsBetween May 01, 2023, and June 20, 2023, 48 patients with severe COVID-19 pneumonia were treated at the Department of Respiratory and Critical Care Medicine of Jinan Fourth People's Hospital. The observation group (21 patients) received standard care and high-dose corticosteroids, (high-dose group). The control group (27 patients) received standard care and low-dose corticosteroids (low-dose group). We collected baseline data and recorded inflammatory marker levels after 3 days of treatment, body temperature recovery time, length of stay, and 28-day all-cause mortality. The results of outpatient follow-up were recorded after 1 month.ResultsThere were no significant differences in 28-day mortality and length of stay. The number of days it took for body temperature to return to normal in the high-dose group was less than in the low-dose group. The high-dose group had significantly more reduced inflammatory factors (C-reactive protein (CRP), interleukin-6 (IL-6). A total of 20 discharged patients were given 8–16 mg of methylprednisolone, depending on chest computed tomography (CT) and clinical symptoms after 1 month; in all discharged patients using oral corticosteroids, CT features improved.ConclusionHigh-dose corticosteroids had a significantly positive effect on the reduction of inflammatory factors and shortening body temperature recovery time. In the treatment of severe COVID-19 pneumonia, early administration of high-dose, short-course corticosteroids should be implemented.

A phase II study of belumosudil for chronic graft-versus-host disease in patients who failed at least one line of systemic therapy in China

BackgroundChronic graft-versus-host disease (cGVHD) is an immune-related disorder that is the most common complication post-allogenic hematopoietic stem cell transplant. Corticosteroids with or without calcineurin inhibitors (CNIs) remain the mainstay of cGVHD treatment for first-line therapy. However, for many patients, cGVHD symptoms cannot be effectively managed and thus require second-line therapy. Currently, there is no approved treatment for second-line cGVHD treatment in China. In this study, belumosudil, a highly selective and potent rho-associated coiled-coil-containing protein kinase-2 inhibitor demonstrated to be effective for cGVHD in the United States and other Western countries, is investigated in patients with cGVHD in China for its overall benefit–risk balance.MethodsThis multicenter, open-label phase II study evaluated the safety, efficacy, and pharmacokinetics of oral belumosudil 200 mg once daily in cGVHD patients who had been treated with at least one line of systemic therapy in China. The primary endpoint was overall response rate (ORR); each individual patient’s response was assessed by the investigator using the 2014 National Institutes of Health consensus criteria. Secondary endpoints were duration of response (DOR), time to response (TTR), changes in Lee Symptom Scale (LSS) score, organ response rate, corticosteroid dose change, CNI dose change, failure-free survival, time-to-next-treatment, overall survival, and safety.ResultsThirty patients were enrolled in the study with a median follow-up time of 12.9 months. ORR was 73.3% (95% confidence interval: 54.1–87.7%) and all responders achieved partial response. Median DOR among responders was not reached and median TTR was 4.3 weeks (range: 3.9–48.1). Fifteen patients (50.0%) achieved clinically meaningful response in terms of reduction in LSS score by ≥ 7 points from baseline. Corticosteroid and CNI dose reductions were reported in 56.7% (17/30) and 35.0% (7/20) of patients, respectively. Most treatment-emergent adverse events (TEAEs) were mild to moderate in severity, with 11 patients (36.7%) experiencing grade ≥ 3 TEAEs. The most common grade ≥ 3 TEAE was pneumonia (n = 5, 16.7%).ConclusionsBelumosudil treatment demonstrated a favorable benefit–risk balance in treating cGVHD patients who previously have had standard corticosteroid therapy in China where approved second-line setting is absent.Trial registrationClinicalTrials.gov identifier NCT04930562.

Suboptimal Response to Biologics in Severe Asthma—A Marker of Humoral Immunodeficiencies

BackgroundAsthmatic patients with antibody deficiencies (AD) have more severe disease and higher risk of exacerbations. No data exists about the efficacy of biologics in severe asthma (SA) patients with AD.The objective of this study was to evaluate the efficacy of biologics in SA patients with and without AD. MethodsA case-control real-life study was conducted including 68 patients divided in two groups: group 1 with SA-AD and group 2 with SA. ResultsTreatment by biologics for 6 months was effective to decrease the number of exacerbations, hospitalizations, and emergency department (ED) visits, to improve the Asthma Control Questionnaire (ACQ) score and proved a systemic corticosteroid sparing effect. Despite benefits, the number of exacerbations, hospitalizations, and ED visits, the mean ACQ score, and the cumulative dose of systemic corticosteroids remain higher in group 1 vs 2, with lower lung function parameters. The rates of responses were inferior in group 1 vs 2 with a decrease by ≥50% of exacerbation rate in 76% vs 97% of patients (p=.006), no hospitalization in 44% vs 91% of patients (p<.001), no ED visit 56% vs 82% of patients (p=.018), significant improvement of ACQ score by ≥0.5 in 68% vs 100% of patients (p<.001), and increase of forced expiratory volume in the first second by >10% in 32% vs 65% of patients (p=.007). ConclusionDespite evident benefits, SA patients with AD have suboptimal responses to biologics compared to those immunocompetent. A multidisciplinary approach is necessary to optimize the management of these patients in practice.

Results of omalizumab treatment in chronic eosinophilic pneumonia: Real-life data.

Recurrences occur when corticosteroid therapy is discontinued or reduced during the treatment of chronic eosinophilic pneumonia (CEP). The probability of recurrence is once in 50% of patients and twice or more in 25%. In such instances, new treatment options are deemed necessary. This study aims to assess the efficacy of omalizumab treatment as a steroid-sparing drug in patients with CEP. The clinical features of patients treated with omalizumab for recurrent CEP were evaluated retrospectively before and after treatment. All data from patients and diagnoses were reviewed. The effects of treatment on recurrence rate, oral corticosteroid (OCS) use and lung functions, peripheral eosinophil values, and symptom scores were evaluated. Radiological regression was also evaluated. In the final analysis, we included ten patients with a median follow-up of 22 months after initiation of omalizumab. During this follow-up period, the results were associated with a significant reduction in the number of asthma attacks per year, the number of CEP relapses, the rate of hospitalization, the amount of corticosteroids consumed daily, and the total corticosteroid dose. In addition, improvement was observed in the symptom scores and lung functions of the patients. Systemic steroids were completely discontinued in two patients receiving omalizumab treatment. In other patients, the mean steroid dose was reduced by 77.2 percent in the first year of omalizumab treatment and 82 percent in the second year, respectively. Nevertheless, there was no elevation in peripheral eosinophil count, and radiological regression was observed. Omalizumab can be an effective treatment for CEP and can be used as a steroid-sparing agent.

Long-term multicenter comparison shows equivalent efficacy of monoclonal antibodies in severe asthma therapy

BackgroundMonoclonal antibodies (biologics) drastically changed severe asthma therapy. Mepolizumab (anti-interleukin (IL) 5), benralizumab (anti-IL5 receptor alpha), and dupilumab (anti-IL4/13) are the most used biologics in this context. While all biologics are efficient individually, the choice of biologic is complicated by insufficient data on their comparative long-term treatment efficacy. Here, we compare the real-life efficacy of these biologics in asthma therapy over 12 months.Methods280 severe asthma patients treated with mepolizumab (129/280, 46%), benralizumab (83/280, 30%) or dupilumab (68/280, 24%) for one year were analyzed retrospectively. Data were collected at baseline and after 6 and 12 months of therapy. Endpoints were changes pulmonary function (PF), exacerbation rate, oral corticosteroid (OCS) use and dose, asthma control test (ACT) score and fractional exhaled nitric oxide (FeNO) levels as well as responder status measured by the recently published “Biologic Asthma Response Score” (BARS).ResultsAll biologics led to significant improvements in PF, ACT and OCS dose. Only Mepolizumab and Benralizumab significantly decreased the exacerbation rate, while only Mepolizumab and Dupilumab significantly decreased FeNO. Responder rates measured by BARS were high across all groups: roughly half of all patients achieved full response and most of the remainder achieved at least partial responder status. Overall, outcomes were similar between groups after both 6 and 12 months.ConclusionsAll biologics showed great efficacy in individual parameters and high responder rates measured by BARS without a clinically relevant advantage for any antibody. Response was usually achieved after 6 months and retained at 12 months, emphasizing the utility of early response assessment.

Efficacy and safety of canakinumab in systemic juvenile idiopathic arthritis, the first Chinese experience

BackgroundSystemic juvenile idiopathic arthritis (sJIA) is a severe form of juvenile arthritis that is characterized by chronic joint inflammation and systemic symptoms such as fever, rash, and organ involvement. Anti-IL-6 receptor monoclonal antibody tocilizumab is an effective treatment. However, some patients still experience persisting or recurrent symptoms and the real-world effectiveness of canakinumab in Chinese patients with sJIA has never been reported. Therefore, this study aimed to assess the efficacy and safety of canakinumab in Chinese patients with sJIA using real-world data.MethodsWe conducted a retrospective study on children with active sJIA. Clinical features, laboratory data, corticosteroid dosage, and adverse events (AEs) were collected at baseline and at 4, 8, 12, and 24 weeks after initiating canakinumab treatment.ResultsSeven female and four male patients were included in the study. All patients had previously been treated with tocilizumab and were administered canakinumab for 12.4 ± 3.4 months. Notably, significant improvements were observed in both clinical signs and symptoms as well as laboratory indicators. Four children under corticosteroid treatment were able to successfully discontinue their corticosteroid therapy: one at week 4, two at week 12, and one at week 24. Notably, there was a significant reduction in the number of tender and swollen joints (P = 0.0059) as well as the systemic juvenile arthritis disease activity score (P < 0.0001). The most common AE was infection, but no patients experienced serious AEs. No cases of macrophage activation syndrome or death were reported during the follow-up period.ConclusionsCanakinumab was found to be potentially efficacious and safe in Chinese patients with sJIA. No new AEs were observed with canakinumab treatment.

Efficacy and Safety of Rilzabrutinib in Pemphigus: PEGASUS Phase 3 Randomized Study

Pemphigus is a rare but life-threatening autoimmune disease requiring long-term treatment that minimizes corticosteroid (CS) exposure while providing consistent disease control. The phase 2 pemphigus study of oral, reversible, covalent Bruton tyrosine kinase inhibitor rilzabrutinib demonstrated rapid and sustained efficacy with well-tolerated safety. Adults (aged 18-80 years) were randomized 1:1 to 400 mg rilzabrutinib (n= 65) or placebo (n= 66) twice daily (with CS ≤ 0.5 mg/kg/d) for 37 weeks in the phase 3 PEGASUS study in moderate-to-severe pemphigus vulgaris/pemphigus foliaceus. The primary endpoint of complete remission from week 29 to week 37 with the amended endpoint CS dose ≤10 mg/d was not significant for 13 of 54 (24%) rilzabrutinib versus 10 of 55 (18%) placebo patients with PV (P= .45). Secondary endpoints showed numerical but nonsignificant improvements with rilzabrutinib (vs placebo) in reduced CS use, prolonged complete remission duration, and faster time to first complete remission. Overall, rilzabrutinib was well-tolerated, with similar adverse events reported in both groups. Using minimal CS dose ≤10 mg/d and excluding remote observations, the primary efficacy endpoint was not met. However, results from a prespecified sensitivity analysis using CS dose ≤5 mg/d, considering all observations, and including all patients support Bruton tyrosine kinase inhibition as a viable therapeutic approach for pemphigus.
