BCD020 rituximab bioanalog compared to standard treatment in juvenile systemic lupus erythematosus: The data of 12 months case-control study. World J Clin Pediatr 2024; 13:89049. [PMID: 38596443 PMCID: PMC11000064 DOI: 10.5409/wjcp.v13.i1.89049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 02/02/2024] [Accepted: 01/30/2024] [Indexed: 03/06/2024] Open
Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is the most frequent and serious systemic connective tissue disease. Nowadays there is no clear guidance on its treatment in childhood. There are a lot of negative effects of standard-of-care treatment (SOCT), including steroid toxicity. Rituximab (RTX) is the biological B-lymphocyte-depleting agent suggested as a basic therapy in pediatric SLE. AIM To compare the benefits of RTX above SOCT. METHODS The data from case histories of 79 children from the Saint-Petersburg State Pediatric Medical University from 2012 to 2022 years, were analyzed. The diagnosis of SLE was established with SLICC criteria. We compared the outcomes of treatment of SLE in children treated with and without RTX. Laboratory data, doses of glucocorticosteroids, disease activity measured with SELENA-SLEDAI, and organ damage were assessed at the time of initiation of therapy and one year later. RESULTS Patients, treated with RTX initially had a higher degree of disease activity with prevalence of central nervous system and kidney involvement, compared to patients with SOCT. One year later the disease characteristics became similar between groups with a more marked reduction of disease activity (SELENA-SLEDAI activity index) in the children who received RTX [-19 points (17; 23) since baseline] compared to children with SOCT [-10 (5; 15.5) points since baseline, P = 0.001], the number of patients with active lupus nephritis, and daily proteinuria. During RTX therapy, infectious diseases had three patients; one patient developed a bi-cytopenia. CONCLUSION RTX can be considered as the option in the treatment of severe forms of SLE, due to its ability to arrest disease activity compared to SOCT.

Abstract
INTRODUCTION Therapy of childhood-onset systemic lupus erythematosus (cSLE) with drugs is unsatisfactory. Some new drugs such as belimumab and rituximab may improve the course of severe cSLE, although there are few reports on treatment efficiency for these new drugs, especially belimumab. CASE PRESENTATION Here we report on a 16-year-old girl who was diagnosed with cSLE at the age of 13. After several immunosuppressive treatments, which included high-dose steroids, hydroxychloroquine sulfate, cyclophosphamide, etc for blood system damage, she showed little clinical improvement and developed severe pericarditis. Induction treatment with a combination of intravenous high-dose steroids, methylprednisolone, and cyclophosphamide was started, but, after 55 days, the patient developed lupus encephalopathy, lung infection, and lupus nephritis. After using high-dose steroids, cyclophosphamide, plasma exchange, gamma globulin, and appropriate anti-pulmonary inflammation drugs, treatment with tacrolimus was attempted but poorly tolerated by the patient and withdrawn. Eventually, in December 2019, belimumab was initiated on an off-label basis as a last resource to treat lupus nephritis. Belimumab was well tolerated by the patient and resulted in a rapid and marked improvement in clinical symptoms and reduction in proteinuria, serum complement levels and anti-double strand DNA antibodies titer; of note, the patient developed no infectious complications. CONCLUSION Treatment with belimumab could result in prompt remission of severe cSLE with multiple organ damage without the pulmonary infection side effects for children deemed intolerant to conventional and second-line induction therapies. Belimumab should be considered as a potentially efficacious treatment in patients in severe childhood-onset systemic lupus erythematosus.

Abstract
BACKGROUND Pediatric lupus nephritis (LN) is one of the most serious manifestations of systemic lupus erythematosus (SLE) in children, determining the outcomes of the disease. There are no standardized treatment protocols for pediatric LN, and the role of biologics has not yet been conclusively defined. OBJECTIVES analyze the safety and efficacy of rituximab biosimilar BCD020 in pediatric patients with lupus nephritis. METHODS in a retrospective cohort study, the data from the case histories of 25 patients with LN (10 boys and 15 girls) with an onset age of 13 (9-16) years, who failed conventional non-biologic treatment or developed corticosteroid dependence/toxicity, were included. The diagnosis was made using Systemic Lupus International Collaborating Clinics (SLICC) classification criteria. Rituximab biosimilar BCD020 was prescribed in a dosage of 375 mg/m2 every week (2-4 infusions) with repeated courses every 6-12 months (2-4 infusions) according to disease activity, B-cell depletion, and IgG levels. The dynamics of clinical and laboratory data, the activity of the disease by SLEDAI, and corticosteroid doses were assessed at the onset and during the rituximab trial. RESULTS The main patient's characteristics were: Pre-rituximab non-biologic conventional treatment included: cyclophosphamide 15 (60%), MMF 8 (32%), azathioprine 3 (12%), hydroxychloroquine 12 (48%), and pulse therapy of methylprednisolone followed by oral methylprednisolone 25 (100%). The time before rituximab was 7.0 (3.0-24.0) months, and the whole observation period was 7.0 (0; 24) months. The initial pre-rituximab treatment slightly reduced SLEDAI levels and the proportion of patients with LN. A significant reduction of SLEDAI, the anti-dsDNA level, proteinuria, hematuria, C4 complement, ESR, and the median corticosteroid dose by 80% from the initial value, as well as the proportion of patients without corticosteroids, was observed after rituximab administration. Two deaths were observed due to catastrophic SLE with macrophage activation syndrome, accompanied by a severe infection (invasive aspergillosis, n = 2). Three patients developed serious adverse events: pneumonia (n = 2), transient agranulocytosis (n = 1) after the third rituximab infusion, and meningitis, caused by Listeria monocytosis, after the first rituximab infusion. Eight patients received antibacterial treatment for different respiratory infections without hospital admissions. CONCLUSIONS Rituximab biosimilar BCD020 showed effectiveness in LN, whereas previous non-biologic treatment was insufficiently effective. Randomized controlled trials are required to evaluate the efficacy and safety of rituximab and evaluate the benefits when compared with conventional SLE treatment.

Abstract
Systemic lupus erythematosus is an immunopathological disease which is characterized by a poor prognosis. Biologics applied in the disease treatment allow reducing the corticosteroid toxicity and controlling the disease.Purpose. To evaluate the efficacy and safety of rituximab therapy in children with systemic lupus erythematosus.Material and methods. The retrospective study included data of 48 patients with systemic lupus erythematosus treated with rituximab. Systemic lupus erythematosus was diagnosed based on the SLICC classification criteria. Patients were assessed at baseline disease status, at the time of rituximab initiation and follow-up. The indications for the rituximab were: lupus nephritis, CNS involvement, and hematological involvement resistant to the standard therapy, and in cases of severe corticosteroid toxicity.Results. During rituximab therapy the significant decrease of the SELENA–SLEDAI activity index was observed. There was a significant decrease of the level of antibodies against dsDNA, normalization of the levels of hemoglobin, ESR, complement C4. The proportion of patients with cytopenia decreased up to their complete absence in patients receiving therapy for three years. The number of patients with active lupus nephritis decreased from 16 at the time of rituximab initiation to 1 after 3 years of therapy. Significant dynamics of proteinuria and hematuria was noted, except for 1 patient. The daily dose of corticosteroids was reduced by 90% from baseline in patients treated for 3 years. Serious adverse events included three deaths in patients with high systemic lupus erythematosus activity with uncontrolled macrophage activation syndrome associated with infections. Various infectious complications, hypogammaglobulinemia, which required replacement therapy with intravenous immunoglobulin, were also recorded.Conclusion. Rituximab can be considered as an option for the treatment of severe forms of systemic lupus erythematosus which are resistant to standard therapy. Further studies are required to evaluate efficacy and safety.

Abstract
IntroductionChildhood systemic lupus erythematosus (cSLE) is a complex multisystem autoimmune disease. In 2019, belimumab was approved for the clinical treatment for cSLE, making it the only biological agent approved for cSLE children aged 5 and older in 60 years.ObjectiveTo review emerging evidence on belimumab in cSLE published up to April 2022, so as to provide information for clinical decision-making.MethodA comprehensive search of relevant publications up to the date of April 2022 in PUBMED, EMBASE, WOS, COCHRANE, ClinicalTrials.gov, CBM, CNKI and WANFANG was performed using the following criteria: (a) English and Chinese language studies; (b) RCT studies, cohort studies, or case-control studies; (c) patients with age <18; (d) Observational studies or case series studies contain more than 5 patients. All relevant literature was independently screened and reviewed by at least two reviewers and the obtained literature data were extracted and reviewed by two authors.ResultsFive publications met the inclusion/exclusion criteria for cSLE: one randomized controlled trial, one retrospective cohort study, and three case series. There was a high degree of heterogeneity among several studies, and the availability of baseline and outcome data provided was uneven.ConclusionAt present, there is a lack of high-quality clinical trials of belimumab in the treatment of cSLE. Based on the current research, it is believed that the use of belimumab can inhibit cSLE activity, reduce the dose of corticosteroids and immunosuppressants, and delay kidney damage. Also it shows clinical benefit in alleviating symptoms of monogenic cSLE refractory to standard therapy. More studies are urgently needed to validate the clinical efficacy of belimumab in cSLE and to evaluate its long-term safety in pediatric populations to promote evidence-based practice.

Abstract
PURPOSE To evaluate the efficacy and safety of low dosages of rituximab (RTX) in the treatment of MuSK-antibody-positive MG patients. PATIENTS AND METHODS We retrospectively analyzed the data of MuSK-antibody-positive MG patients who were treated with low dosages of RTX from January 2018 to October 2021. The long-term treatment response to RTX was assessed by Myasthenia Gravis Foundation of America (MGFA) post-interventional status (PIS), Myasthenia Gravis Status and Treatment Intensity (MGSTI), dosage of steroid, MG-related activities of daily living (MG-ADL) and myasthenic muscle score (MMS) at the end of follow-up. RESULTS Clinical improvement was observed in all eight patients with follow-up for 8 to 29 months after treatment. At the last visit, complete stable remission had been achieved in one patient, pharmacologic remission in three patients, minimal manifestations status in three patients and improved in one patient based on the MGFA-PIS criteria. MGSTI level 2 or better had been reached in six (75%) patients at the last visit. The steroid dosage decreased from 60 mg at baseline to 15 mg at the last follow-up (p = 0.011). The average MG-ADL score decreased from 11 (range 7 to 15) to 0 (range 0 to 3; p = 0.011), and the MMS improved from 38.5 (range 24 to 60) to 100 (range 90 to 100; p = 0.012). These differences were all statistically significant. During RTX treatment and subsequent follow-up, 1 patient reported minor post-infusion malaise. CONCLUSION Low-dose RTX is effective and safe for treating anti-MuSK antibody positive MG patients. A long-term response is observed after treatment. Larger prospective studies are required to provide further evidence.

Abstract
Systemic lupus erythematosus (SLE) is a chronic, multisystem, autoimmune disease of unknown etiology, whose hallmark is the production of autoantibodies. B cells are promising targets for novel SLE therapies. In 2011, belimumab (Benlysta®), a fully humanized monoclonal antibody inhibiting B-cell activation and proliferation, was the first medication in 50 years to be approved by the US Food and Drug Administration to treat adult SLE. This review discusses the current experience with B-cell-targeted therapies, including those targeting B-cell-surface antigens (rituximab, ocrelizumab, ofatumumab, obinutuzumab, obexelimab, epratuzumab, daratumumab), B-cell survival factors (belimumab, tabalumab, atacicept, blisibimod), or B-cell intracellular functions (ibrutinib, fenebrutinib, proteasome inhibitors), for the management of SLE. It focuses on ongoing clinical trials and real-world post-marketing use, where available, including their safety profiles, and concludes with our recommendations for B-cell-centric approaches to the management of SLE.

Abstract
Background Although much progress has been made in the diagnosis of early-stage lung adenocarcinoma (ES-LUAD), the prognosis for ES-LUAD patients with rapid recurrence is still poor. Importantly, there is currently no effective and precise method to screen patients who may develop rapid recurrence. Therefore, it is necessary to identify potential differentially expressed genes (DEGs) in ES-LUAD patients with rapid recurrence and non-rapid recurrence. Methods Affymetrix GeneChip Human Transcriptome Array was used to identify DEGs between ES-LUAD patients with rapid recurrence and non-rapid recurrence. Rapid recurrence was defined as recurrence-free survival (RFS) ≦ 1 year and non-rapid recurrence was defined as RFS ≧ 3 years. The biological functions of the DEGs were analyzed by GO and KEGG pathway enrichment analyses. The protein–protein interaction (PPI) network of identified DEGs was conducted by STRING and Cytoscape software. The expression level of crucial hub genes and tumor-infiltrating lymphocytes (TILs) was verified by immunohistochemistry (IHC). Results A total of 416 DEGs were identified between ES-LUAD patients with and without rapid recurrence. The results of GO analysis revealed that 2 of the top 10 categories in the domain of cellular component, 2 of the top 10 in the domain of molecular function, and 9 of the top 10 in the domain of biological process were functionally related to immunity. The results of KEGG analysis showed that 6 of the top 8 pathways were functionally involved in immune regulation and inflammatory response. The PPI network analysis identified ten crucial nodal protein, including EGFR, MMP9, IL-1β, PTGS2, MMP1, and 5 histone proteins, which constituted 25 key interactions. IL-1β and PTGS2 expression were closely related to immunity and IHC analysis further revealed that low expression of IL-1β and PTGS2 is associated with rapid recurrence. Kaplan–Meier analysis further revealed that LUAD patients with lower IL-1β or PTGS2 expression had a worse RFS. When the TIL density of CD3+, CD4+, CD8+ and CD20+ subsets was less than 20%, ES-LUAD patients have a higher probability of rapid recurrence. Conclusion There were significant differences in the expression of immune-related genes between patients with rapid recurrence and patient with non-rapid recurrence. Immune-related genes such as IL-1β and PTGS2 and TIL density (20%) play important roles in rapid recurrence of ES-LUAD. This study provided a theoretical basis for distinguishing the two types of patients from an immunological perspective.

Abstract
A Euro-Lupus regimen of low-dose intravenous cyclophosphamide (CFA) is commonly used to treat severe organ manifestations of systemic lupus erythematosus (SLE), particularly lupus nephritis (LN). There are no data on the distributions and dynamics of immune cell populations in patients with various treatment outcomes. The circulating immune cells of 11 female SLE patients were assessed before and after Euro-Lupus regimen (cumulative dose of 3000 mg CFA) by flow cytometry together with those of 16 healthy women. A subanalysis was performed in LN patients who achieved complete remission (CR; n = 3), partial remission (PR; n = 4), and no response (NR; n = 2). In SLE, the Euro-Lupus regimen decreased the percentage and absolute count of B cells; increased the percentage of CD8+ T cells, T regulatory cells, neutrophils, and monocyte subsets; and activated T and NK cells compared to healthy controls (P < 0.050). Patients with LN achieving CR had significantly lower proportions of CD27+ B memory cells compared to poor responders (PR/NR, P = 0.035). The post-treatment percentages and absolute numbers of B cells, T cells, NK cells, monocytes, and neutrophils showed high inter-individual variability with no association with treatment outcome. Our pilot study revealed the dynamics of changes in immune cell populations in SLE patients during a Euro-Lupus regimen, mainly the lowering of B cells. In LN patients who achieved CR, a lower proportion of CD27+ B memory cells was evident compared to poor responders (PR/NR). Further studies on usefulness of monitoring immune cells for treatment response prediction on larger cohorts are needed.

Abstract
Potent covalent inhibitors of Bruton's tyrosine kinase (BTK) based on an aminopyrazole carboxamide scaffold have been identified. Compared to acrylamide-based covalent reactive groups leading to irreversible protein adducts, cyanamide-based reversible-covalent inhibitors provided the highest combined BTK potency and EGFR selectivity. The cyanamide covalent mechanism with BTK was confirmed through enzyme kinetic, NMR, MS, and X-ray crystallographic studies. The lead cyanamide-based inhibitors demonstrated excellent kinome selectivity and rat pharmacokinetic properties.

Abstract
OBJECTIVE To systematically review and summarize the available literature regarding the effectiveness and safety of biologics in the treatment of juvenile-onset systemic lupus erythematosus. METHODS PubMed was systematically searched for relevant literature (2012-2017 inclusive) using the following criteria: (1) patients diagnosed with juvenile-onset systemic lupus erythematosus (≤18 years at diagnosis); (2) treatment with any biological agent; and (3) outcome measures assessing effectiveness and safety. Systematic literature reviews, meta-analyses, randomized controlled trials, cohort studies, case control studies, cross sectional surveys and case-series with ≥3 patients were included. Independent extraction of articles by two authors using predefined criteria was performed. The quality of each study was assessed using CASP tools and Oxford CEBM Levels of Evidence. RESULTS Nine articles met inclusion criteria: six cohort studies, two case series and one pilot study, totalling 230 patients. All but one article reported the effects of rituximab, the other those of belimumab. Overall, patients had active disease refractory to standard of care regimens using corticosteroids and immunosuppressants. Available evidence for rituximab demonstrated improvements in disease activity, complement levels and anti-dsDNA titres accompanying a steroid-sparing effect. CONCLUSION Rituximab can be considered an effective treatment in juvenile-onset systemic lupus erythematosus patients with severe disease manifestations and/or refractory disease. Based on current evidence, use of belimumab in juvenile-onset systemic lupus erythematosus patients cannot be recommended. The long-term safety of these biological agents remains uncertain. Further prospective studies, ideally robust randomized controlled trials, are urgently needed to obtain more accurate data on the effectiveness and long-term safety of rituximab, belimumab and other biologics in juvenile-onset systemic lupus erythematosus.

Abstract
Juvenile systemic lupus erythematosus (jSLE), mixed connective tissue disease (jMCTD), and Sjögren syndrome (jSS) are systemic autoimmune and inflammatory disorders with distinct patterns of organ involvement. All are characterized by autoantibody formation, with antinuclear (ANA) and anti-double-stranded DNA common in jSLE, ANA with high-titer ribonucleoprotein antibody in jMCTD, and Sjögren syndrome A and Sjögren syndrome B antibodies + ANA in jSS. Recognition, monitoring, and management for primary care providers are discussed, focusing on the role of primary physicians in recognizing and helping maintain optimal health in children with these potentially life-threatening diseases.

Abstract
OBJECTIVES To evaluate the efficacy and safety of rituximab for treating pediatric systemic lupus erythematosus (pSLE). STUDY DESIGN We performed a systematic review to evaluate the efficacy and safety of rituximab in children with pSLE. Data from studies performed before July 2016 were collected from MEDLINE, the Cochrane Library, Scopus, and the International Rheumatic Disease Abstracts, with no language restrictions. Study eligibility criteria included clinical trials and observational studies with a minimal sample size of 5 patients, regarding treatment with rituximab in patients with refractory pSLE (aged <18 years at the time of diagnosis). Independent extraction of articles was performed by 2 investigators using predefined data fields. RESULTS Twelve case series met the criteria for data extraction for the systematic review with a good quality assessment according to an 18-criteria checklist using a modified Delphi method. Among them, 3 studies were multicenter and 3 were prospective. The total number of patients was 272. Studies collected patients with active disease refractory to steroids and immunosuppressant drugs. Refractory lupus nephritis was the most common indication (33%). Acceptable evidence suggested improvements in renal, neuropsychiatric and haematological manifestations, disease activity, complement and anti-double stranded Desoxy-Nucleo-Adenosine, with a steroid-sparing effect. However, there was poor evidence suggesting efficacy on arthralgia, photosensitivity, and mucocutaneous manifestations of SLE in children. An overall acceptable safety profile with few major adverse events was shown. CONCLUSION Rituximab exhibited a satisfactory profile regarding efficacy and safety indicating that this agent is a promising therapy for pSLE and should be further investigated.

Abstract
Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disorder in which 20 % of patients are diagnosed in childhood. Childhood-onset SLE is associated with higher morbidity and mortality than adult-onset SLE. The aims of disease management with early immunosuppression are to decrease disease activity and improve quality of life. A multidisciplinary approach is necessary due to the complexity of lupus in pediatric patients. It is important to provide patients with high quality of care and to instill ownership of their disease process from a young age to prepare them to manage this life-long illness. This article reviews current management of SLE in children.
