Analysis of immunopathogenesis of psoriasis in the dynamics of treatment

Оbjective — to analyze the parameters of the immune system of the organism in patients with psoriasis before and after treatment. Materials and methods. The parameters of cellular immunity in an organism estimated after the change of relative and absolute amount of T- (CD3+) and B- (CD19+) of lymphocytes and subpopulations (CD4+, CD8+, CD16+, CD25+, CD71+, CD30+, CD95+). To identify of surface structures of lymphocytes the method of direct immune fluorescence was used where fluorescent label was attached to anti-CD of mononuclear antibodies of series Leu of the firm «Becton Dikinson» (USA). Calculations were conducted on the laser instantaneous cytofluorometer of the firm «Baston» (USA). Results and discussions. The most positive influence on the parameters of the cellular link of the immune system of the organism was found in patients with psoriasis who received immunobiological therapy with the medication etanercept in combination with narrowband (311 nm) phototherapy. After treatment in patients of this group, due to a significant decrease in the production of TNF and its serum concentration, the pro-inflammatory changes in the cellular link of the immune system decreased, the number of lymphocytes with the an early activation marker, which initiated a further cytokine cascade of development and prolongation of inflammation decreased significantly. In addition, the established reduction in the number of CD30+ lymphocytes is an indirect factor indicating the switching of the Tx2 response (autoimmune manifestations) to Tx1, and hence the achievement of the clinical and immunological remission of the psoriatic process. It is extremely important for the functioning of the immune system the decrease in the content of activated lymphocytes that express the Fas-receptor as due to the increased lymphocyte apoptosis, namely, T-cytotoxic lymphocytes, and autoimmune and proliferative changes took place inherent in the exacerbation of the psoriatic process. Conclusions. It was established that all our schemes of psoriasis treatment have immunorehabiting properties but their degree of severity was different. The most effective treatment scheme is the combined use of etanercept and UVB therapy, thus proliferative and inflammatory changes in the skin reduced, antigenic loading decreased, the level of CICs, autosensibilization and autoimmune disorders also decreased.

Real-life data of etanercept efficacy and safety in juvenile idiopathic arthritis: a 24-month retrospective study at a single center

ABSTRACT Objective The aim of this study was to assess the efficacy and safety of etanercept (ETA) use in juvenile idiopathic arthritis (JIA). Methods The 24-month data of patients with JIA on etanercept in a single center were evaluated retrospectively. Response to treatment was assessed according to 10-joint Juvenile Arthritis Disease Activity Score (JADAS10), and JIA-American College of Rheumatology (ACR) improvement criteria. Safety assessments were based on adverse event (AE) reports. Results The study included 152 patients with JIA. The mean age at diagnosis of JIA was 8.5 ± 4.4 years, and treatment with ETA started at a mean age of 11.1 ± 4.4 years. The mean duration of ETA use was 16 ± 11.1 months. The mean JADAS10 score at baseline was 18.5 ± 5.9. By the third month, it had reduced to 8.6 ± 6.6 and by the sixth month to 5.7 ± 6. By the twelfth month, the JADAS10 score was 4.9 ± 6.7, and by the twenty-fourth month, it had worsened to 7.3 ± 7.8. ACR50 response was achieved in 79.6% of patients at 3 months, 67.1% at 6 months, 79.3% at twelfth months, 70.7% at the twenty-fourth month. During ETA treatment, 10 patients required hospitalization for serious infections. Conclusion Etanercept is a safe and effective option for patients with JIA. However, variations in response between JIA subtypes highlight the need for individualized treatment strategies.

Comparison of Two Financial Incentives to Encourage the Use of Adalimumab Biosimilars: Results of a French Experiment Close to Clinicians.

In 2018, the French government introduced two mutually exclusive financial incentives to increase etanercept and insulin glargine biosimilar use. The general case redirects 20% of the price difference between the reference product and its biosimilars to hospitals for every biosimilar dispensed in community pharmacies from hospital prescriptions. The experimental case redirects 30% to prescribing clinical units after hospital selection. Adalimumab was added to these incentives in 2019, after its first biosimilar was launched. This retrospective observational study aimed to compare both general and experimental incentives after 19 months to assess the impact of directly incentivizing clinical units for adalimumab biosimilars. The monthly number of adalimumab boxes dispensed in community pharmacies was linked to the corresponding hospital's prescription using IQVIA Xponent data from November 2017 to October 2020. The monthly mean rate of adalimumab biosimilars was compared between incentive groups and subgroups depending on hospitals' prior experience with the etanercept experimental case. General case hospitals had a significantly lower mean biosimilar uptake (16.7% vs 23.2%, p = 0.029) than those included in the experimental case. Twenty-three of the 40 hospitals in the experimental case and ten out of the 91 hospitals studied in the general case had already taken part in the etanercept experiment. Biosimilar uptake was higher, but not statistically significant, for hospitals with prior experience in the adalimumab general case group (p = 0.086). This study confirmed that incentivizing close to physicians was more effective in increasing the biosimilar rate. It also suggested that previous incentive experience positively influenced biosimilar penetration.

Drug-induced lupus erythematosus in childhood: Case-based review.

Drug-induced lupus erythematosus (DILE) is the development of lupus-like syndrome following a drug exposure. DILE has been reported less frequently among children than adults. In this study, we present four children with DILE and similar published cases through a systematic literature review. We report four children (three girls and one boy) who developed DILE associated with the use of topiramate, doxycycline, etanercept, and ethosuximide. Three of them were positive for anti-histone antibodies. In all patients, the drug was discontinued and symptoms resolved completely. The literature review revealed 48 articles describing 61 children with DILE. In the evaluation of 65 patients (our 4 patients and 61 patients from the literature), the most frequently reported drugs associated with DILE were ethosuximide (n = 13) and minocycline (n = 12). Fever (n = 33), arthralgia (n = 31), rash (n = 30), and arthritis (n = 29) were the most common clinical manifestations. Antinuclear antibody (ANA) was positive in 93.5% of patients and anti-histone antibodies were detected in 72.2% of the patients. As for treatment, the responsible drug was discontinued in all patients, and corticosteroids were initiated in 53.3%. Improvement was achieved in 92.0% of patients. For children presenting with SLE features, proper drug history is crucial since DILE may be more frequent than anticipated. An association of the relevant drug with the symptoms, and resolution of symptoms on drug withdrawal provides evidence for the diagnosis of DILE.

Effectiveness and safety of biological and target synthetic drugs treatment for psoriatic arthritis: a systematic review with network meta-analysis

BackgroundPsoriatic arthritis (PA) is a chronic inflammatory systemic arthritis that can result in loss of functional capacity and joint deformation. This systematic review assessed the effectiveness and safety of biological and target synthetic drugs for treating PA.MethodsWe searched for randomized clinical trials (RCTs) that evaluated the use of Adalimumab, Etanercept, Infliximab, Golimumab, Secukinumab, Certolizumab Pegol and Tofacitinib in the main general databases and clinical trial registers databases. The primary outcomes were ACR 50, PsARC, and serious adverse events. Two independent reviewers performed study selection and data extraction. Network meta-analyses were conducted using a random effects model and frequentist approach. The CINeMA software was used to assess the certainty of evidence.ResultsWe included 33 RCTs (n = 11,034). The results from the network meta-analysis for the ACR 50 at 6-months follow-up showed that all drugs were superior to placebo, with Secukinumab (high certainty of evidence), Infliximab (very low certainty of evidence) and Adalimumab (high certainty of evidence) ranking the highest. Regarding the PsARC (at 6-months follow-up), all drugs, except for Golimumab (very low certainty of evidence), were superior to placebo, with Etanercept (low certainty of evidence), Infliximab (low certainty of evidence) and Certolizumab Pegol (low certainty of evidence) being the most effective drugs. There were no significant differences in the risk of serious adverse events between the drugs and placebo. Golimumab (very low certainty of evidence), Secukinumab (low certainty of evidence), and Adalimumab (very low certainty of evidence) ranked the highest for safety.ConclusionsIn conclusion, based on the balance between efficacy and safety, Secukinumab and Adalimumab may be the preferred options among the evaluated drugs for treating patients with PsA. However, caution is necessary when interpreting the safety findings, as they are supported by evidence of low to very low certainty. Consequently, the balance between benefits and potential risks may change as new safety evaluation studies become available.Protocol registrationPROSPERO: CRD42022315577

Comparisons of infection events associated with tumor necrosis factor inhibitors in patients with inflammatory arthritis: A systematic review and network meta-analysis.

Objective: To compare the risk of infection in inflammatory arthritis patients treated with tumor necrosis factor (TNF) inhibitors. Methods: PubMed, Embase, and the Cochrane Library were systematically searched from inception to 28 December 2023 for randomized controlled trials (RCTs) assessing TNF inhibitors and reporting infections. Subsequently, pairwise and network meta-analyses were conducted to determine odds ratios (ORs) and the corresponding 95% confidence intervals (CIs). Results: A total of 61 RCTs involving 20,458 patients were included. Pairwise meta-analysis revealed that certolizumab pegol was significantly associated with an increased risk of serious infection compared to placebo (OR:2.28, 95% CI: 1.13-4.62). Both adalimumab and certolizumab pegol were also significantly associated with an increased risk of any infection compared to placebo (OR:1.18, 95% CI: 1.06 to 1.30 and OR:1.40, 95% CI: 1.11 to 1.76, respectively). Moreover, a network meta-analysis indicated that certolizumab pegol and infliximab were associated with a higher risk of serious infection compared to other TNF inhibitors. In the cumulative ranking of any infection risk, certolizumab pegol had the highest risk compared with others. TNF inhibitors increased the risk of tuberculosis but not that of herpes zoster. Conclusion: Available evidence indicates etanercept and golimumab are likely associated with a lower risk of infection compared to other TNF inhibitors in inflammatory arthritis. For patients at a heightened risk of infection, prioritizing the use of etanercept and golimumab may be advisable to minimize patient risk. Systematic Review Registration: identifier CRD42022316577.

OP39 Real-World Evidence Of Post-Incorporation Use Of Monoclonal Antibodies For Psoriasis In The Brazilian Public Health System

IntroductionPsoriasis is an immune-mediated chronic inflammatory disease that can affect the skin, joints, and nails. The treatment of the disease is offered by the Brazilian Public Health System (SUS) in accordance with the guidelines of the Ministry of Health. The aim of this study was to analyze real-world data (RWD) on the implementation and use of monoclonal antibodies (mAbs) for the treatment of psoriasis in the SUS.MethodsThis is a descriptive study that used national administrative data on drug dispensing from the Open Room for Health Intelligence Situation (SABEIS-SUS) from October 2019 to December 2021. Adult individuals (≥18 years) with vulgar (L40.0), generalized pustular (L40.1), gutata (L40.4) and other (L40.8) psoriasis who used the mAbs adalimumab, etanercept, risankizumab, secukinumab and ustekinumab were included.ResultsThe year of implementation of mAbs for the treatment of psoriasis in the SUS was October 2019 (adalimumab, etanercept and secukinumab) and May 2020 (ustekinumab). Risankizumab was implemented in April 2022. The number of individuals using mAb grew from 366 in 2019 to 10,146 in 2021. In 2019, 2020 and 2021, the proportion of individuals using each mAbs was 62.3 percent, 46.2 percent and 35.4 percent (adalimumab), 7.9 percent, 3.3 percent and 2.7 percent (etanercept), 29.8 percent, 33.8 percent and 30.5 percent (secukinumab), 0 percent, 16.7 percent and 31.4 percent (ustekinumab), respectively.ConclusionsThe number of mAbs users has greatly increased from 2019 to 2021, which may indicate a successful implementation of the psoriasis treatment in SUS. Most individuals used adalimumab in the year of the first implementation. However, the proportion of users of this mAb has greatly decreased after the implementation of ustekinumab. This reduction should not be so expressive since adalimumab and ustekinumab are recommended in different lines of treatment. The low proportion of etanercept use may be due the fact the medication is indicated for individuals up 18 years of age. This study provides important real-word evidence for monitoring the implementation of mAbs for psoriasis treatment in Brazil.

Опыт успешного применения этанерцепта у ребенка с артритом, ассоциированным с энтезитом

Aim: demonstration of a clinical case of the successful use of etanercept in a child with еnthesitis-аssociated аrthritis. Key points. Еnthesitis-аssociated аrthritis is one of the clinical variants of juvenile idiopathic arthritis. The initial therapy of еnthesitis-аssociated аrthritis includes nonsteroidal anti-inflammatory drugs (NSAIDs) and non-biological disease-modifying drugs, the ineffectiveness of which is an indication for the appointment of genetically engineered drugs, in particular, the inhibitor of tumor necrosis factor-α etanercept. Conclusion. Currently, for the treatment of еnthesitis-аssociated аrthritis, if the use of NSAIDs and non-biological disease-modifying drugs is ineffective, genetically engineered drugs should be prescribed, in particular etanercept, which allows to achieve drug remission. Keywords: еnthesitis-аssociated аrthritis, etanercept, children.

Angioedema in a Patient with Ankylosing Spondylitis Treated with Etanercept

Ankylosing spondylitis (AS) is a chronic inflammatory disease of unknown pathogenesis. Nonsteroidal antiinflammatory and biologic drugs are used in its treatment. A 38 year old male patient diagnosed with AS was admitted to the rheumatology outpatient clinic due to swelling in both upper eyelids and around the eyes recurring for 1 month. He was at the 5th month of etanercept treatment. With the current clinic, etanercept-induced angioedema was primarily considered in the patient. Angioedema resolved spontaneously 2 days after discontinuation of the drug. In conclusion, although angioedema associated with etanercept use may develop rarely, it can lead to life-threatening results in some cases. From this point of view, it is important for clinicians to closely observe patients using etanercept and to inform the patient about side effects.

Incidence of septic arthritis in patients with ankylosing spondylitis and seropositive rheumatoid arthritis following TNF inhibitor therapy.

Septic arthritis (SA) is a serious complication occurring in the joints, and its risk increases with immunosuppressive therapy. This study investigated whether TNF inhibitors increase the risk of SA in patients with AS and seropositive RA (SPRA). We searched the South Korean Health Insurance Review and Assessment Service database for incident cases of AS and SPRA between 2010 and 2020. SA was defined using the diagnostic code M00 and hospital admission. Cox-proportional hazards analysis was conducted to compare the incidence of SA according to TNF inhibitor (infliximab, etanercept, adalimumab/golimumab) use during follow-up. Of the 145 129 patients analysed, 1170 (0.8%) developed SA during the follow-up period. Older age; male sex; SPRA diagnosis; comorbidities of hypertension (HTN), diabetes mellitus (DM) and chronic pulmonary disease (CPD); and infliximab and etanercept use increased the incidence of SA in the overall population. However, in patients with AS, only age and renal disease were predictors of SA, and TNF inhibitors did not increase the incidence of SA. Meanwhile, patients with SPRA treated with TNF inhibitors were prone to SA regardless of TNF inhibitor type, and age, HTN, DM and CPD were associated with SA. The incidence of SA was prominent after the first year of commencing TNF inhibitor therapy, for both AS and SPRA. TNF inhibitors increase the incidence of SA, specifically in patients with SPRA, but not AS. Importantly, age, comorbidities and the early time period after starting TNF inhibitors were associated with SA, which should be considered simultaneously when initiating TNF inhibitor therapy.

First-line biologic therapy with tumor necrosis factor inhibitors for psoriatic arthritis: a prospective observational study

Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects multiple joints. It is associated with psoriasis and treated with synthetic and biologic drugs. The objective of this study was to assess the outcomes of patients who received biologic therapy with tumor necrosis factor (TNF) inhibitors in terms of effectiveness, safety, functionality, and quality of life. A prospective observational study was performed at a single center in Belo Horizonte, Brazil. Patients with PsA who received their first TNF inhibitor treatment were followed up for 12 months. Disease activity was measured using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Clinical Disease Activity Index (CDAI). Functionality was measured using the Health Questionnaire Assessment (HAQ), and quality of life was evaluated using the European Quality of Life Five Dimensions (EQ-5D). Multiple linear regression was used to identify predictors of the clinical response at 12 months. A total of 143 patients treated with adalimumab or etanercept were evaluated. Most of the clinical measures were significantly improved at 12 months. However, 31%-51% of the patients did not achieve good clinical control. No differences were observed between adalimumab and etanercept, except for poor functionality at 12 months among patients treated with etanercept. The main predictors of a worse clinical response were female sex, etanercept use, poor functionality, or lower quality of life at baseline. The main adverse reactions were alopecia, headache, injection site reaction, sinusitis, flu, dyslipidemia, and infections. TNF inhibitor therapy was effective and safe. However, despite improvements in clinical measures, most patients did not achieve satisfactory control of the disease.

Risk of malignancy in patients with psoriasis receiving systemic medications: A nested case-control study.

Large-scale, real-world studies on the side effects of systemic therapies (including biologics) in patients with psoriasis are limited. We aimed to calculate the risk of malignancy in patients with psoriasis who were treated with systemic medications. Nested case-control analyses were performed among psoriasis patients without a history of malignancy. We recruited 4188 patients with newly diagnosed psoriasis and successive malignancies, and 8376 matched controls from the National Health Insurance Research Database in Taiwan. The therapy duration was within 5 years before malignancy onset and further stratified into two groups according to the duration of medication usage. Multivariate conditional logistic regression adjusted for potential confounders was used to estimate malignancy risk associated with systemic treatments. Among psoriasis patients, long-term (> 12 months) treatment with cyclosporine increased the risk of malignancy compared with no exposure (odds ratio, 1.57; p= 0.01). Short-term (≤ 12 months) or long-term (> 12 months) use of other systemic treatments, including methotrexate, azathioprine, systemic retinoids, mycophenolate mofetil, sulfasalazine, etanercept, adalimumab, and ustekinumab, was not associated with an increased risk of malignancy in patients with psoriasis. Long-term treatment with cyclosporine increased the risk of malignancy in patients with psoriasis by 1.57-fold.

31783 Etanercept in toxic epidermal necrolysis: In support of standard of care

Background: Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a severe cutaneous adverse reaction (SCAR) that is a result of an immune-mediated cascade orchestrated by activated cytotoxic T-cells leading to the release of granulysin, perforin, and interferon-gamma. Despite its high morbidity and mortality, there is no established standard of care for the pharmacological management of SJS/TEN patients. The rationale behind use of etanercept, a TNF-alpha inhibitor, has been supported by case reports and small mechanistic studies, though the current literature is limited and dispersed.

Disease-specific ADRs of TNF-α inhibitors as reported by patients with inflammatory rheumatic diseases: a registry-based prospective multicenter cohort study

ABSTRACT Background The extent to which adverse drug reactions (ADRs) of biologics differ per immune-mediated inflammatory disease (IMID), and the relevance of tailoring ADR information per IMID is not fully investigated. We aimed to compare patient-reported ADRs attributed to adalimumab and etanercept between different inflammatory rheumatic diseases (IRDs). Research design and methods ADR reports from IRD patients were extracted from the Dutch Biologic Monitor. ADR frequencies were compared using Fischer–Freeman–Halton exact test and the influence of covariates was assessed using binomial logistic regression. Results A total, of 729 participants were included, of which 354 participants reported 887 unique ADRs. ADR frequencies were not significantly different between the IRDs. Rheumatoid arthritis and ankylosing spondylitis including axial spondyloarthritis patients had an increased risk of ADRs related to ‘Respiratory, thoracic and mediastinal disorders’ and as compared to psoriatic arthritis patients. Etanercept use, combination therapy with methotrexate and/or corticosteroids, and age also influenced the risk of reporting specific ADRs. Conclusions There were no differences in frequencies and nature of patient-reported ADRs attributed to adalimumab and etanercept between different IRDs. However, more research is needed to align patients’ and health-care professionals’ perspectives to improve knowledge on disease-specific ADRs.

Toxic epidermal necrolysis in adult patients: Experience from the West Australian Collaboration.

Toxic epidermal necrolysis (TEN) is a rare and life-threatening mucocutaneous disease triggered by a reaction to a drug. Despite reported mortality of 30%, management differs between healthcare settings. Our hospital was established in February 2015 becoming the new state burns centre in Western Australia (WA). Following this, we collaborated on comprehensive multidisciplinary guidelines for the management of TEN. These guidelines are updated annually to reflect the weight of emerging evidence in managing TEN. Our aim was to review the management and outcomes of TEN patients presenting to our hospital between February 2015 and May 2021 (inclusive). We collected data for 10 patients on year, age, ethnicity, gender, medical history, culprit drug and exposure, SCORTEN, length of stay, maximum percentage of skin detachment, mucosal surface involvement, ophthalmic amniotic membrane transplant, burns unit input/admission, intensive care unit admission, weight, systemic treatment(s), complications and outcome. We excluded 7 out of 17 flagged patients who did not strictly meet the definition of TEN as greater than 30% epidermal detachment, with epidermal detachment defined as bullae, erosions, and/or positive Nikolsky. We found that the mortality rate in WA from TEN is improving compared with two previous WA studies, with a mortality rate in our study of 20% (2 deaths). Though limited by small sample size and retrospective design, our study suggests a shift towards at least one systemic therapy per patient (most commonly cyclosporine), the growing use of etanercept and the ophthalmic use of amniotic membrane transplants. It demonstrates the importance of burns unit input and the utility of comprehensive multidisciplinary guidelines. While the management and outcomes of TEN patients in WA are continuing to improve, we support calls for large registry data to facilitate evidence growth and collaboration for this rare life-threatening condition.

Biological therapy in psoriatic arthritis patients with and without previous biologic experience

Objective: this study evaluated the biological therapy effects on disease activity, functionality, quality of life, drug survival, and safety of patients with psoriatic arthritis naïve and experienced in biological therapy. Methods: a oneyear prospective observational study was performed. The outcomes assessed were drug survival, disease activity, functionality, quality of life, and safety. Multiple linear regression was used to assess predictive factors for clinical response.Results: a total of 205 patients were included, 155 of whom were biologic naïve and 50 biologic experienced. Drug survival rate was greater for naïve patients than experienced patients at 6 months, but not at 12 months. Drug survival rates were 71.5% for naïve patients and 70.0% for experienced patients at 12 months. All clinical parameters improved for both biologic naïve and experienced patients. At 12 months, 63% of naïve patients and 52% of experienced patients had an improvement in their quality of life. Besides, 48% of naïve patients and 42% of experienced patients had an improvement in functionality. The axial disease improved in 67% of naïve individuals and 56% of experienced patients. Good control of peripheral disease was achieved by 49% of naïve patients and 44% of experiencedpatients. Female sex, use of etanercept or infliximab, and lower functionality or quality of life at baseline were the main predictors of poor clinical response. Conclusion: Patients’ health improved after starting biological therapy. In general, biologic experienced patients had more adverse reactions and lesser effectiveness.

Pancreatic islet transplantation in type 1 diabetes: 20-year experience from a single-centre cohort in Canada

Islet transplantation offers an effective treatment for selected people with type 1 diabetes and intractable hypoglycaemia. Long-term experience, however, remains limited. We report outcomes from a single-centre cohort up to 20 years after islet transplantation. This cohort study included patients older than 18 years with type 1 diabetes undergoing allogeneic islet transplantation between March 11, 1999, and Oct 1, 2019, at the University of Alberta Hospital (Edmonton, AB, Canada). Patients who underwent islet-after-kidney transplantation and islet transplantation alone or islet transplantation before whole-pancreas transplantation (follow-up was censored at the time of whole-pancreas transplantation) were included. Patient survival, graft survival (fasting plasma C-peptide >0·1 nmol/L), insulin independence, glycaemic control, and adverse events are reported. To identify factors associated with prolonged graft survival, recipients with sustained graft survival (≥90% of patient follow-up duration) were compared with those who had non-sustained graft survival (<90% of follow-up duration). Multivariate binary logistic regression analyses were done to determine predictors of sustained graft survival. Between March 11, 1999, and Oct 1, 2019, 255 patients underwent islet transplantation and were included in the analyses (149 [58%] were female and 218 [85%] were White). Over a median follow-up of 7·4 years (IQR 4·4-12·2), 230 (90%) patients survived. Median graft survival was 5·9 years (IQR 3·0-9·5), and graft failure occurred in 91 (36%) patients. 178 (70%) recipients had sustained graft survival, and 77 (30%) had non-sustained graft survival. At baseline, compared with patients with non-sustained graft survival, those with sustained graft survival had longer median type 1 diabetes duration (33·5 years [IQR 24·3-41·7] vs 26·2 years [17·0-35·5]; p=0·0003), median older age (49·4 years [43·5-56·1] vs 44·2 years [35·4-54·2]; p=0·0011), and lower median insulin requirements (0·53 units/kg per day [0·45-0·67] vs 0·59 units/kg per day [0·48-0·70]; p=0·032), but median HbA1c concentrations were similar (8·2% [7·5-9·0] vs 8·5% [7·8-9·2]; p=0·23). 201 (79%) recipients had insulin independence, with a Kaplan-Meier estimate of 61% (95% CI 54-67) at 1 year, 32% (25-39) at 5 years, 20% (14-27) at 10 years, 11% (6-18) at 15 years, and 8% (2-17) at 20 years. Patients with sustained graft survival had significantly higher rates of insulin independence (160 [90%] of 178 vs 41 [53%] of 77; p<0·0001) and sustained improvements in glycaemic control mixed-main-effects model group effect, p<0·0001) compared with those with non-sustained graft survival. Multivariate analyses identified the combined use of anakinra plus etanercept (adjusted odds ratio 7·5 [95% CI 2·7-21·0], p<0·0001) and the BETA-2 score of 15 or higher (4·1 [1·5-11·4], p=0·0066) as factors associated with sustained graft survival. In recipients with sustained graft survival, the incidence of procedural complications was lower (23 [5%] of 443 infusions vs 17 [10%] of 167 infusions; p=0·027), whereas the incidence of cancer was higher (29 of [16%] of 178 vs four [5%] of 77; p=0·015) than in those with non-sustained graft survival; most were skin cancers (22 [67%] of 33). End-stage renal disease and severe infections were similar between groups. We present the largest single-centre cohort study of long-term outcomes following islet transplantation. Although some limitations with our study remain, such as the retrospective component, a relatively small sample size, and the absence of non-transplant controls, we found that the combined use of anakinra plus etanercept and the BETA-2 score were associated with improved outcomes, and therefore these factors could inform clinical practice. None.

Etanercept in axial spondyloarthritis – treatment efficacy

The beginning of the 21st century was marked by a simultaneous changes in view on pathogenesis, diagnostics and treatment of axial spondyloarthritis (axSpA). Anti-TNFα inhibitors were the first biologics prescribed in axSpA. 20 year after the biological treatment was first prescribed we have enough data to understand their long-term efficacy.The aim of this study is to evaluate the long-term efficacy of etanercept in patients with axial spondyloarthritis based on data published in periodicals and clinical practice.Patients and methods. An analysis of publications from medical database and data from the St. Petersburg register of patients with rheumatic diseases (n=68) was performed to assess the effectiveness of etanercept in axSpA treatment in the long-term perspectives. Descriptive statistics methods were used.Results. In clinical studies and in real word practice, etanercept has shown high efficiency in reducing clinical, laboratory and visual manifestations of non-radiographic and radiographic axial spondyloarthritis at early and advanced stages of their development.Conclusions. In the long term, the use of etanercept is associated with an increasing slowdown in structural progression while maintaining a stable clinical and laboratory improvement. Discontinuation of treatment in the majority of patients leads to exacerbation of axSpA. At the same time, the low immunogenicity of etanercept allows the resumption of axSpA treatment with a high probability of re-achieving the lost effect with a low probability of secondary ineffectiveness or anaphylaxis.

Maternal and Fetal-Placental Effects of Etanercept Treatment During Rats' Pregnancy.

Etanercept is a tumor necrosis factor alpha (TNF-α) inhibitor chronically used to treat autoimmune diseases. However, the use of etanercept during pregnancy still needs to be further investigated. The aim of this study is to evaluate the etanercept treatment during pregnancy, analyzing maternal reproductive performance, fetal outcomes, and placental repercussions. Wistar rats (200–250 g) were mated and randomly distributed into two experimental groups: control and etanercept (n = 10 animals/group). Treatments with etanercept (0.8 mg/kg, s.c.), or saline (control group) were carried out on days 0, 6, 12, and 18 of gestation. On the morning of the 21st day of pregnancy, rats were euthanized in a CO2 chamber and submitted to laparotomy to remove the fetuses, placentas, ovaries, and maternal organs. There were no differences between groups in the following parameters: water and food consumption; placental efficiency; reproductive parameters, including number of corpora lutea and implants, reabsorption, and pre- and post-implantation losses. However, etanercept treatment increased liver weight, reduced fetal and placental weight, decreased the placental junction zone, reduced the percentage of normal fetuses, and increased visceral or skeletal fetal abnormalities. Therefore, etanercept resulted in damages more related to fetus and placenta. However, more studies with different doses are required to better predict possible injuries elicited using etanercept during pregnancy.

Risk of Acute Anterior Uveitis in Ankylosing Spondylitis According to the Type of Tumor Necrosis Factor-Alpha Inhibitor and History of Uveitis: A Nationwide Population-Based Study.

Background: We evaluated the risk of acute anterior uveitis (AAU) in patients with ankylosing spondylitis (AS) during treatment with tumor necrosis factor-alpha inhibitors (TNFis). Methods: This study was performed on AS patients using the Korean National Health Insurance claims database. We analyzed the first and total occurrence of AAU during the first 2 years of TNFis use according to the type of TNFis. Additionally, the occurrence of AAU was assessed in subgroups with or without prior AAU before TNFis initiation. Results: In total, 5938 AS patients initiated TNFis use between 2009 and 2017 and used them for more than 2 years. Among them, 1488 (25.1%) patients had a history of AAU before starting TNFis treatment. Compared to adalimumab, the use of etanercept (hazard ratio [HR] 1.77) increased the risk of AAU. The incidence rate ratio (IRR) of AAU with etanercept was significantly higher than that of adalimumab (IRR 1.78). The IRR of AAU was also higher for etanercept than adalimumab use in patients with (IRR 1.86) and without (IRR 2.92) a history of AAU. Conclusion: These data suggest that compared to anti-TNF-alpha monoclonal antibodies, etanercept has a higher incidence of AAU regardless of a history of AAU.
