Effects of Antithymocyte Globulin, Basiliximab, and Induction-Free Treatment in Living Donor Kidney Transplant Recipients on Tacrolimus-Based Immunosuppression.

OBJECTIVES: Induction treatment in renal transplant is associated with better graft survival. However, intensified immunosuppression is known to cause unwanted side effects such as infection and malignancy. Furthermore, the effects of the routine use of immunosuppressants in low-risk kidney transplant recipients are still not clear. In this study, we assessed the first-year safety and efficacy of induction treatment. MATERIALS AND METHODS: We examined first living donor kidney transplant patients who were on tacrolimus based immunosuppression therapy. We formed 3 groups according to the induction status: antithymocyte globulin induction, basiliximab induction, and no induction. We collected outcome data on delayed graft function, graft loss, creatinine levels, estimated glomerular filtration rates, acute rejection episodes, hospitalization episodes, and infection episodes, including cytomegalovirus infection and bacterial infections. RESULTS: We examined a total of 126 patients (age 35 ± 12 years; 65% male). Of them, 25 received antithymocyte globulin, 52 received basiliximab, and 49 did notreceive any induction treatment. We did not observe any statistically significant difference among the 3 groups in terms of acute rejection episodes, delayed graft function, and first-year graft loss. The estimated glomerular filtration rates were similar among the groups. Overall bacterial infectious complications and cytomegalovirus infection showed similar prevalence among all groups. Hospitalization was less common in the induction-free group. CONCLUSIONS: In low-risk patients, induction-free regimens could be associated with a better safety profile without compromising graft survival. Therefore, induction treatment may be disregarded in first living donor transplant patients who receive tacrolimusbased triple immunosuppression treatment.

Double-dose investigation of aflibercept in neovascular age-related macular degeneration (DIANA): a real-world study.

BACKGROUND: To investigate the clinical effects of double-dose (4 mg) aflibercept treatment in neovascular age-related macular degeneration (nAMD), compared with the standard-dose (2 mg) treatment. METHODS: A total of 108 eyes from 97 patients with nAMD and received intravitreal aflibercept 2 mg and/or 4 mg treatment were retrospectively reviewed. The changes of central macular thickness (CMT)/ pigmental epithelium detachment height and the recurrence rate of exudation during the 12-month follow-up were compared between the 2 mg group and the 4 mg group. Self-control comparisons (2 mg switch to 4 mg) were also made between two regimens. RESULTS: Compared with the 2 mg group, tendencies of lower intraretinal fluid incidence and more CMT reduction were observed in the 4 mg group. The later one was also observed when eyes switching from 2 mg to 4 mg regimen. The median remission interval was 5 months in the 4 mg group, 2 months longer than the 3 months in the 2 mg group (P = 0.452). Injections needed in the 4 mg group were 3.644 ± 1.670, less than the 4.286 ± 2.334 injections in the 2 mg group within 12 months as well (P = 0.151). However, no associated vision benefits were gained from the double-douse regimen. No markedly increased-intraocular pressure events, or other adverse events were found in two groups. CONCLUSIONS: Compared to the aflibercept 2 mg treatment in nAMD, tendencies of anatomic gains and relieving treatment burden were brought by the aflibercept 4 mg treatment. This study may have additional importance, given the further application of high-dose aflibercept in real-world settings.

Phase 1 first-in-human dose-escalation study of ANV419 in patients with relapsed/refractory advanced solid tumors.

Patients with advanced cancer, previously treated with immune checkpoint blockade therapy, may retain residual treatment when undergoing the initial infusion of experimental monotherapy in phase 1 clinical trials. ANV419, an antibody-cytokine fusion protein, combines interleukin-2 (IL-2) with an anti-IL-2 monoclonal antibody, aiming to stimulate the expansion of CD8 T and natural killer lymphocytes while restricting regulatory T lymphocytes. In the recent publication of the phase 1 dose escalation study of ANV419, a notable gap exists in detailed information regarding patients' prior antitumoral treatments, specifically programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) targeted monoclonal antibodies. Some patients likely retained residual anti-PD-1/PD-L1 monoclonal antibodies, potentially influencing the outcomes of ANV419. In a separate clinical cohort, we retrospectively measured the residual concentration of nivolumab and pembrolizumab, revealing persistent serum concentrations of anti-PD-1/PD-L1 antibodies even months after treatment cessation. This underscores the importance of comprehensively documenting prior immunotherapy details in clinical trials. Such information is crucial for understanding potential interactions that may impact both immunological and clinical effects.

Significant elevation of serum CA19-9 and CA242 levels induced by dulaglutide.

The use of dulaglutide, a common medication for managing type 2 diabetes, rarely causes elevated pancreatic tumour markers. Here, we report the case of a woman in her mid-60s with diabetes for over 10 years. The patient presented with markedly elevated serum CA19-9 and CA242 levels revealed during a routine health examination despite being asymptomatic. She had been receiving dulaglutide injections for 16 months. Imaging and interventional assessments did not reveal any hepatobiliary, gastrointestinal or pancreatic neoplasm. After excluding alternate diagnoses, the patient was determined to exhibit an adverse reaction to dulaglutide use. Management involved the discontinuation of dulaglutide, which resulted in normalisation of serum CA19-9 and CA242 levels within 6 weeks. This case underscores the importance of discontinuing dulaglutide and monitoring changes in the biomarker levels in asymptomatic patients receiving dulaglutide, rather than immediately resorting to imaging and endoscopic examinations.

Tebentafusp in the treatment of metastatic uveal melanoma - the first patient treated in the Czech Republic.

BACKGROUND: Uveal melanoma is a rare cancer, in which metastases occur in approximately one half of cases. In metastatic disease, the prognosis is unfavorable and the median of survival does not exceed 6 months. Effective treatment options were very limited up to date. Tebentafusp is a bispecific fusion protein, which as the first drug proved efficacy in uveal melanoma. CASE: The patient was referred for suspected uveal melanoma of the left eye. She was treated for Hodgkin's disease in the past. Primarily, the tumor was treated by radiosurgery with radiotherapy of a small lesion of the vertebral body. However, later the patient had to undergo bulbus enucleation with confirmation of a large tumor category pT4b. PET/CT revealed metastases of the bones and the liver; simultaneously, haplotype A*02: 01 was confirmed. The patient underwent radiotherapy of the sternum and later, after confirmation of payment from the health insurance company, she started treatment with tebentafusp. The first three doses were administered during admission to the hospital, with a need to treat cytokine release syndrome by corticosteroids. Later, the administration was performed in an out-patient regimen, without complications, except for a transient elevation of transaminases. The first CT restaging confirmed stable disease; however, the second restaging confirmed a new osteolytic lesion in the processus of Th11. Because of progression, the treatment with tebentafusp was withdrawn after 6 months. Unfortunately, the lesion could not be treated by radiotherapy. Two months later, the patient was urgently admitted to the hospital because of right-sided hemiplegia; MRI revealed bleeding metastatic lesion in the brain stem. CONCLUSION: In this case report, we present the case of the first patient treated with this drug in the Czech Republic.

Case report: Recombinant human type II tumour necrosis factor receptor-antibody fusion protein induced occult hepatitis B virus reactivation leading to liver failure.

Recombinant human type II tumour necrosis factor receptor-antibody fusion protein (rh TNFR:Fc) is an immunosuppressant approved for treating rheumatoid arthritis (RA). This case report describes a case of hepatitis B reactivation in a patient with drug-induced acute-on-chronic liver failure. A 58-year-old woman with a history of RA was treated with rh TNFR:Fc; and then subsequently received 25 mg rh TNFR:Fc, twice a week, as maintenance therapy. No anti-hepatitis B virus (HBV) preventive treatment was administered. Six months later, she was hospitalized with acute jaundice. HBV reactivation was observed, leading to acute-on-chronic liver failure. After active treatment, the patient's condition improved and she recovered well. Following careful diagnosis and treatment protocols are essential when treating RA with rh TNFR:Fc, especially in anti-hepatitis B core antigen antibody-positive patients, even when the HBV surface antigen and the HBV DNA are negative. In the case of HBV reactivation, liver function parameters, HBV surface antigen and HBV DNA should be closely monitored during treatment, and antiviral drugs should be used prophylactically when necessary, as fatal hepatitis B reactivation may occur in rare cases. A comprehensive evaluation and medication should be administered in a timely manner after evaluating the patient's physical condition and closely monitoring the patient.

A heart transplant center experience with basiliximab induction strategies: A double edged sword?

BACKGROUND: The use of induction immunosuppression for heart transplantation (HT) is debated given the uncertain benefit and potential risks of infection and malignancy. METHODS: This is a retrospective single-center analysis of 475 consecutive HT recipients from 2003 to 2020 grouped by use of induction with basiliximab group (BG) and the no basiliximab group (NBG). Subgroup analysis by era compared pre-2016 standard-basiliximab (BX) induction and 2016-2020 with selective-BX use as part of a calcineurin-inhibitor-sparing regimen. RESULTS: When adjusted for confounders (sex, age, PRA, eGFR), the BG was less likely to have acute cellular rejection (ACR) (OR.42, p < .001), but had more antibody mediated rejection (AMR) (OR 11.7, p < .001) and more cardiac allograft vasculopathy (CAV) (OR 3.8, p = .04). There was no difference between BG and NBG in the incidence of malignancies or infections. When stratified by era (pre-2016 vs. 2016-2020), ACR remained less common in the BG than the NBG (36% vs. 50%, p = .045) groups, while AMR remained more common (9.7 vs. 0% p = .005). There was no significant difference in conditional survival comparing pre-and post-2016 NBG (HR 2.20 (95% CI.75-6.43); however, both pre-2016 BG and post-2016 BG have significantly higher mortality (HR 2.37 [95% CI 1.02-5.50) and HR 2.69 (95% CI 1.08-6.71), p = .045 and.03, respectively]. CONCLUSION: Basiliximab reduces the incidence of ACR but increases the risk of AMR, CAV, and may be associated with increased mortality. Mechanistic studies are needed to describe a potential T-cell-escape mechanism with enhanced humoral immunity.

SPECTRA Phase 2b Study: Impact of Sotatercept on Exercise Tolerance and Right Ventricular Function in Pulmonary Arterial Hypertension.

BACKGROUND: This study aims to assess the impact of sotatercept on exercise tolerance, exercise capacity, and right ventricular function in pulmonary arterial hypertension. METHODS: SPECTRA (Sotatercept Phase 2 Exploratory Clinical Trial in PAH) was a phase 2a, single-arm, open-label, multicenter exploratory study that evaluated the effects of sotatercept by invasive cardiopulmonary exercise testing in participants with pulmonary arterial hypertension and World Health Organization functional class III on combination background therapy. The primary end point was the change in peak oxygen uptake from baseline to week 24. Cardiac magnetic resonance imaging was performed to assess right ventricular function. RESULTS: Among the 21 participants completing 24 weeks of treatment, there was a significant improvement from baseline in peak oxygen uptake, with a mean change of 102.74 mL/min ([95% CIs, 27.72-177.76]; P=0.0097). Sotatercept demonstrated improvements in secondary end points, including resting and peak exercise hemodynamics, and 6-minute walk distance versus baseline measures. Cardiac magnetic resonance imaging showed improvements from baseline at week 24 in right ventricular function. CONCLUSIONS: The clinical efficacy and safety of sotatercept demonstrated in the SPECTRA study emphasize the potential of this therapy as a new treatment option for patients with pulmonary arterial hypertension. Improvements in right ventricular structure and function underscore the potential for sotatercept as a disease-modifying agent with reverse-remodeling capabilities.

Intravitreal Aflibercept vs Laser Therapy for Retinopathy of Prematurity: Two-Year Efficacy and Safety Outcomes in the Nonrandomized Controlled Trial FIREFLEYE next.

Importance: Prospective long-term data after retinopathy of prematurity (ROP) treatment with anti-vascular endothelial growth factor injections vs laser therapy are scarce. The FIREFLEYE (Aflibercept for ROP IVT Injection vs Laser Therapy) next trial is prospectively evaluating the long-term efficacy and safety outcomes following ROP treatment with intravitreal aflibercept vs laser therapy. Objective: To evaluate 2-year ophthalmic and safety outcomes after 0.4-mg aflibercept injection or laser therapy in the 24-week randomized (2:1) FIREFLEYE trial (FIREFLEYE outcomes previously reported). Design, Setting, and Participants: This prospective nonrandomized controlled trial performed in 24 countries in Asia, Europe, and South America (2020-2025) follows up participants treated in the FIREFLEYE randomized clinical trial (2019-2021) through 5 years of age. Participants included children born very or extremely preterm (gestational age ≤32 weeks) or with very or extremely low birth weight (≤1500 g) who were previously treated with a 0.4-mg injection of aflibercept compared with laser therapy for severe acute-phase ROP. Data for the present interim analysis were acquired from March 18, 2020, to July 25, 2022. Interventions: Complications of ROP treated at investigator discretion (no study treatment). Main Outcomes and Measures: Efficacy end points included ROP status, unfavorable structural outcomes, ROP recurrence, treatment for ROP complications, completion of vascularization, and visual function. Safety end points included adverse events and growth and neurodevelopmental outcomes. Results: Overall, 100 children were enrolled (median gestational age, 26 [range, 23-31] weeks; 53 boys and 47 girls). Of these, 21 were Asian, 2 were Black, 75 were White, and 2 were of more than 1 race. At 2 years of age, 61 of 63 children (96.8%) in the aflibercept group vs 30 of 32 (93.8%) in the laser group had no ROP. Through 2 years of age, 62 of 66 (93.9%) in the aflibercept group and 32 of 34 (94.1%) in the laser group had no unfavorable structural outcomes. No new retinal detachment occurred during the study. Four children in the aflibercept group (6.1%) were treated for ROP complications before 1 year of age (2 had preexisting end-stage disease and total retinal detachment; 1 had reactivated plus disease; and 1 had recurrent retinal neovascularization not further specified). Most children were able to fix and follow a 5-cm toy (aflibercept group, 118 of 122 eyes [96.7%] among 63 children; laser group, 62 of 63 eyes [98.4%] among 33 children). High myopia was present in 9 of 115 eyes (7.8%) among 5 children in the aflibercept group and 13 of 60 eyes (21.7%) among 9 children in the laser group. No relevant differences in growth and neurodevelopmental outcomes by Bayley Scales of Infant and Toddler Development, Third Edition and Vineland Adaptive Behavior Scales, Second Edition were identified. Conclusions and Relevance: In this nonrandomized follow-up of a randomized clinical trial comparing treatment of severe acute-phase ROP with 0.4-mg injection of aflibercept and laser, disease control was stable and visual function was appropriate in children through 2 years of age. No adverse effects on safety, including growth and neurodevelopment, were identified. These findings provide clinically relevant long-term information on intravitreal aflibercept injection therapy for ROP. Trial Registration: ClinicalTrials.gov Identifier: NCT04015180.

Comparison of ranibizumab, aflibercept, and dexamethasone implant monotherapy in treatment-naive eyes with diabetic macular edema: A 12-month real-life experience.

PURPOSE: To compare the functional and anatomical outcomes of ranibizumab, aflibercept, and dexamethasone implant monotherapy in treatment-naive eyes with diabetic macular edema (DME) in real-life conditions. METHODS: In this retrospective cohort study, data were obtained from the hospital database of treatment-naive patients diagnosed with DME with at least 12 months of follow-up. Best corrected visual acuity (BCVA) and central retinal thickness (CRT) at baseline, third month, sixth month, ninth month, and 12th month were recorded. In addition, a subgroup analysis was performed based on having good (below 0.4 log of minimum angle of resolution [logMAR]) or poor (0.4 logMAR and above) vision. RESULTS: A total of 219 eyes of 142 patients were included in the study. The change in the mean BCVA from baseline to 12th month was from 0.62 logMAR to 0.42 logMAR (P < 0.001) in the ranibizumab group, from 0.56 logMAR to 0.39 logMAR (P < 0.001) in the aflibercept group, and from 0.46 logMAR to 0.5 logMAR (P = 0.653) in the dexamethasone group. There was no significant difference between the treatment groups at any time point (P > 0.05). The mean amount of CRT change was statistically significant at 12 months in all groups (ranibizumab: -175.4 µm, aflibercept: -153.3 µm, dexamethasone: -71.4 µm) (P < 0.05). In eyes with initially good vision, the final BCVA at 12 months was significantly better in the ranibizumab group compared to the dexamethasone group (P = 0.008). The aflibercept group had better visual acuity than the dexamethasone group, but there was no statistically significant difference (P = 0.059). There was no significant difference in final BCVA in eyes with initially poor vision. No serious ocular/systemic complications were noted. CONCLUSION: At the 12th month, a significant decrease in CRT was achieved in all treatment groups, whereas only ranibizumab and aflibercept groups had a significant BCVA increase. In eyes with initially good vision, the final BCVA at 12 months was better in the ranibizumab group compared to the dexamethasone group, whereas it was similar in all groups having initially poor vision.

Long-term dynamic changes and influencing factors of corneal morphology after multiple intravitreal injections of anti-VEGF drugs.

To observe alterations in corneal morphology caused by repeated intravitreal injections of anti-vascular endothelial growth factor (VEGF). Prospective cohort study. Seventy-seven eyes were treated with intravitreal injection of anti-VEGF from June 2021 to March 2023. There were 25 eyes of neovascular age-related macular degeneration (nAMD), 24 eyes of diabetic macular edema (DME), and 28 eyes of retinal vein occlusion (RVO). Aflibercept was used in 37 eyes and Ranibizumab was used in 40 eyes. 3 + PRN was used. Corneal endothelium and corneal thickness were measured using a corneal endothelial microscope. The data related to central corneal thickness, corneal endothelial cell density (ECD), average cell size, coefficient of variation (CV), proportion of hexagonal cells (Hex%) was collected. A comparison was also made between baseline and the dynamic changes of all indexes 1 year following the last injection. It was observed that in comparison to baseline, ECD and Hex% decreased significantly after the 3rd injection of Aflibercept and Ranibizumab. However, ECD did not decrease further and remained at the same level as after the last injection. Hex% and average cell size increased to a certain extent in comparison to the last injection. All the changes were found to be statistically significant (P < .01). After 3 injections, ECD in DME group was markedly lower than that in nAMD and RVO group, but the CV in DME group was higher than that in nAMD as well as RVO groups, and all the differences were statistically significant (P < .05). Following intravitreal anti-VEGF therapy, DME is more likely than other disorders to result in a decrease in ECD. Repeated intravitreal injections of anti-VEGF drugs can reduce the Hex% and ECD to a certain extent. After the last injection, Hex% can progressively recover, and ECD can remain stable without further declining. After injections, ECD in DME group was found to be significantly lower than that in nAMD and RVO groups, but CV in DME group was significantly higher in comparison to the other 2 groups. In patients with macular edema, repeated intravitreal injections of anti-VEGF may have certain effects on corneal morphology. Patients with diabetes mellitus in particular should pay special attention to corneal safety following repeated intravitreal injections if they have significantly reduced ECD at baseline.

Retinal and choroidal efficacy of switching treatment to faricimab in recalcitrant neovascular age related macular degeneration.

Aim of this study was to evaluate the efficacy of switching treatment to faricimab in neovascular age-related macular degeneration (nAMD) from other anti-VEGF agents. Fifty-eight eyes of fifty-one patients with nAMD and a full upload series of four faricimab injections were included. Demographic data, multimodal imaging and treatment parameters were recorded. The primary outcome measures were changes in central subfield thickness (CST) and subfoveal choroidal thickness (SFCT). A subgroup analysis was performed for eyes with prior ranibizumab (R) or aflibercept (A) treatment. Mean injection intervals before and after switching were comparable (33.8 ± 11.2 vs. 29.3 ± 2.6 days; p = 0.08). Mean CST of 361.4 ± 108.1 µm prior to switching decreased significantly to 318.3 ± 97.7 µm (p < 0.01) after the third faricimab injection, regardless of prior anti-VEGF treatment (p < 0.01). Although SFCT slightly improved for the whole cohort from 165.8 ± 76.8 µm to 161.0 ± 82,8 µm (p = 0.029), subgroup analysis did not confirm this positive effect (subgroup R: p = 0.604; subgroup A: p = 0.306). In patients with a suboptimal response to aflibercept or ranibizumab in nAMD, farcimab can improve CST and slightly improve or maintain SFCT. Further prospective randomized trials are warranted.

Association between the arm-to-choroidal circulation time and clinical profile in patients with polypoidal choroidal vasculopathy.

PURPOSE: To investigate the association between the arm-to-choroidal circulation time (ACT) on indocyanine green angiography (IA) and clinical profile in patients with polypoidal choroidal vasculopathy (PCV). STUDY DESIGN: Single-center retrospective study. METHODS: We included 38 eyes of 38 patients with PCV diagnosed using multimodal imaging and did not undergo previous treatment. All patients were treated with monthly aflibercept injections for 3 months and treat-and-extend regimens for the subsequent 12 months. Posterior vortex vein ACT was assessed on the first visit using Heidelberg IA. The patients were divided into two groups: ACT ≥20 s (L group; eight eyes) and ACT <20 s (S group; 30 eyes). The clinical profiles before and after treatment were analyzed to assess associations with ACT. RESULTS: The mean ACT was 16.39±3.3 s (L group: 21.25±1.49 s, women:men=2:6, mean age: 77.3±6.5 years; S group: 15.10±2.17 s, women:men=7:23, mean age: 75.5±6.9 years). No significant difference was observed in the mean subfoveal choroidal thickness between the L and the S groups (176±75 µm vs. 230±79 µm, P=0.10). However, there were significant differences between the L and S groups in retinal fluid accumulation and hemorrhage recurrence (eight/eight eyes, 100% vs. 13/30 eyes, 43%, P<0.001), mean aflibercept injections (8.8±1.6 vs. 7.0±1.6, P<0.01) during the 12-month period, and the number of polypoidal lesions (1.8±0.7 vs. 1.3±0.5, P<0.05). CONCLUSION: Patients with PCV and ACT >20 s are more likely to experience exudative change recurrence in the retina during treatment because they have more polypoidal lesions.

Switching to the aflibercept (3 mg) therapy for treatment-resistant wet age-related macular degeneration: 1-year outcomes.

This study aimed to elucidate 1-year outcomes following switching to the aflibercept (3 mg) therapy for treatment-resistant wet age-related macular degeneration (wAMD). In this prospective, open-label, non-controlled clinical trial, 18 patients with wAMD who had multiple recurrences or persistent exudation despite intravitreal injections of anti-vascular endothelial growth factor agents (except aflibercept) received a 3-mg intravitreal aflibercept injection every 4 weeks. Each patient received 3 to 8 injections. The central retinal thickness and fibrovascular pigment epithelial detachment height decreased significantly at 1 month after initiation of the aflibercept injection, and the values were 146 and 163.2 µm, respectively, at the final visit. The morphological improvement was sustained. The intraretinal and subretinal fluid was completely absorbed at the end of the follow-up. The logMAR vision increased from baseline 0.68 to 0.59 (P < .05). No ocular or systemic adverse events occurred. The intravitreal injection of 3-mg aflibercept seems to be feasible in the treatment of wAMD unresponsive to other anti-vascular endothelial growth factor agents.

Efficacy and safety of single-dose anti-thymocyte globulin versus basiliximab induction therapy in pediatric kidney transplant recipients: A retrospective comparative cohort study.

BACKGROUND: This study aimed to compare the efficacy and safety of basiliximab (BAS) versus a single dose of anti-thymocyte globulin (r-ATG) induction therapy in pediatric kidney transplant recipients (KTRs). METHODS: This single-center retrospective comparative cohort study included all pediatric KTRs from May 2013 to April 2018 and followed up to 12 months. In the first period, all recipients received BAS, while from May 2016, a single 3 mg/kg dose of r-ATG was instituted. Maintenance therapy consisted of a calcineurin inhibitor plus prednisone plus azathioprine or mycophenolate. RESULTS: A total of 227 patients were included (BAS, n = 113; r-ATG, n = 114). The main combination of immunosuppressive drugs was tacrolimus, prednisone, and azathioprine in both groups (87% vs. 88%, p = .718). Patients receiving r-ATG showed superior survival-free of the composite endpoint (acute rejection, graft loss, or death; 76% vs. 61%, p = .003; HR 2.08, 1.29-3.34, p = .003) and lower incidence of biopsy-proven acute rejection (10% vs. 21%, p = .015). There was no difference in the overall incidence of CMV infection (33% vs. 37%, p = .457), PTLD (1% vs. 3%, p = .309), 30-day hospital readmissions (24% vs. 23%, p = .847), and kidney function at 12 months (86 ± 29 vs. 84 ± 30 mL/min/1.73m2, p = .614). CONCLUSIONS: These data suggest that induction therapy with a single 3 mg/kg dose of r-ATG is associated with higher efficacy for preventing acute rejection and similar safety profile compared to BAS.

Rilonacept use in lupus pericarditis.

OBJECTIVES: Lupus pericarditis affects 22% of patients with systemic lupus erythematosus (SLE), is associated with worse outcomes, and often requires immunosuppression. Rilonacept is an interleukin-1 receptor antagonist approved for the treatment of recurrent idiopathic pericarditis, but its efficacy in lupus pericarditis is unknown. Here, we report the efficacy of rilonacept in a case series of patients with lupus pericarditis. METHODS: We describe a case series of 4 patients with refractory lupus pericarditis treated with rilonacept in the Johns Hopkins Lupus Center. All patients met the 2012 SLICC criteria for SLE. Refractory lupus pericarditis was defined as recurring or persistent typical pericardial pain symptoms despite standard-of-care treatment including at least one immunosuppressant. RESULTS: Four patients with refractory pericarditis were included. All patients were women, age ranged 26-44 years, 2 patients reported White, 1 Black, and 1 Hispanic ethnicity. Extra-pericardial SLE manifestations were heterogeneous among patients. Only 1 of 3 patient had elevated CRP (not measured in one). Two patients were previously treated with anakinra with initial response, but pericarditis redeveloped in both. Rilonacept led to complete resolution of pericardial symptoms in 3 patients, and partial resolution (40%) in 1, within 2 weeks. CONCLUSIONS: Rilonacept successfully treated lupus pericarditis in this case series. Rilonacept should be considered for the treatment of lupus pericarditis.

Luspatercept in low-risk myelodysplastic syndromes: a paradigm shift in treatment strategies.

INTRODUCTION: In patients with myelodysplastic syndromes (MDS), anemia is prevalent affecting 80%-85% of low-risk (LR-MDS) patients, with 40% eventually requiring red blood cell (RBC) transfusions. Except forlenalidomide, exclusively approved for those with deletion of chromosome 5q,erythropoiesis-stimulating agents (ESAs) are the primary treatment choice for low-risk patients. Those unresponsive to ESAs face limited alternatives, eventually necessitating long-term RBC transfusions, leading to secondary iron overload and adversely affecting quality of life (QoL). AREA COVERED: Luspatercept is a pioneering erythroid maturation agent. It received approval by both the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) for treating adults experiencing transfusion-dependent anemia associated with LR-MDS or ß-thalassemia. Recently, the FDA approved luspatercept as first- line therapy in patients with very low- to intermediate-risk MDS who require RBC transfusions and have not previously received ESAs. This review summarizes the historical impact of luspatercept intreating LR-MDS unresponsive to ESAs and illustrates its potential benefit asfrontline therapy in MDS and its employment in patients with myelofibrosis-induced anemia. EXPERT OPINION: Luspatercept has revolutionized the therapeutic paradigm of LR-MDS, for which there was a limited therapeutic arsenal, especially in the setting of patients who did not respond or fail after ESA treatment.
