Anti-tumour necrosis factor treatment for the prevention of ischaemic events in patients with deficiency of adenosine deaminase 2 (DADA2).

To evaluate the impact of anti-Tumour Necrosis Factor-α (anti-TNF) treatment on the occurrence of vasculitic ischaemic events in patients with deficiency of adenosine deaminase 2 (DADA2). A retrospective analysis of DADA2 patients referred from six centres to Great Ormond Street Hospital for Children was conducted. Ischaemic events, vasculitic disease activity, biochemical, immunological, and radiological features were compared, before and after anti-TNF treatment. A total of 31 patients with genetically confirmed DADA2 were included in the study. The median duration of active disease activity prior to anti-TNF treatment was 73 months (inter-quartile range [IQR] 27.5-133.5 months). Twenty seven/31 patients received anti-TNF treatment for a median of 32 months (IQR 12.0-71.5 months). The median event rate of central nervous system (CNS) and non-CNS ischemic events before anti-TNF treatment was 2.37 per 100 patient-months (IQR 1.25-3.63); compared with 0.00 per 100 patient-months (IQR 0.0-0.0) post-treatment (p< 0.0001). Paediatric vasculitis activity score (PVAS) was also significantly reduced: median score of 20/63 (IQR 13.0-25.8/63) pre-treatment vs. 2/63 (IQR 0.0-3.8/63) following anti-TNF treatment (p< 0.0001), with mild livedoid rash being the main persisting feature. Anti-TNF treatment was not effective for severe immunodeficiency or bone marrow failure, which required haematopoietic stem cell transplantation (HSCT). Anti-TNF treatment significantly reduced the incidence of ischaemic events and other vasculitic manifestations of DADA2, but was not effective for immunodeficiency or bone marrow failure.

Real-world clinical and endoscopic outcomes after one year tofacitinib treatment in ulcerative colitis.

Tofacitinib, an oral Janus kinase inhibitor, is approved for the treatment of moderate to severe ulcerative colitis (UC). We evaluated clinical and endoscopic efficacy, safety and drug survival of tofacitinib up to one year in a real-world cohort. In this retrospective cohort study, 36 UC patients were included who received tofacitinib. The primary outcome was combined with steroid-free clinical remission [Simple Clinical Colitis Activity Index (SCCAI) ≤2] and endoscopic improvement (Mayo score ≤1) at 52 weeks. Secondary outcomes included clinical (SCCAI drop ≥3) and endoscopic response (Mayo score drop ≥1), biochemical remission [fecal calprotectin (FC) ≤150 mg/kg and C-reactive protein ≤5 mg/L), safety and drug survival. Median disease duration was 7 (3-14) years and 89 and 42% of patients failed prior anti-tumor necrosis factor (anti-TNF) and vedolizumab treatment, respectively. Combined corticosteroid-free clinical remission and endoscopic improvement were observed in 8/36 patients (22%), 6/35 (17%) and 12/31 (39%), at 16, 36 and 52 weeks, respectively. Corresponding combined clinical and endoscopic response rates were 15/36 (42%), 12/35 (34%), 15/31 (48%) and biochemical remission rates were 11/33 (33%), 10/32 (31%) and 10/29 (34%). Nine infections (two herpes zoster) led to dose reduction or (temporary) drug withdrawal. Permanent withdrawal occurred in 14/36 patients (33%) after a median duration of 9 (5-30) weeks. Drug survival at 1 year was 60%. Patients that failed anti-TNF were less likely to discontinue tofacitinib treatment early compared to patients without prior anti-TNF use (hazard ratio 0.20, 95% confidence interval 0.06-0.65). In a refractory UC population, combined steroid-free clinical remission and endoscopic improvement were found in 39% of patients at 1 year.

Real-world experience with tofacitinib in ulcerative colitis: a systematic review and meta-analysis.

Background and aims:Tofacitinib is a Janus kinase inhibitor (JAKi) recently approved for the treatment of moderate to severe ulcerative colitis (UC) based on robust efficacy and safety data derived from OCTAVE clinical trials. Evidence on the outcomes of tofacitinib therapy in real-world UC patients is needed, as a number of these patients would be deemed ineligible for clinical trials. We have therefore summarised data derived from observational, real-world evidence (RWE) studies on the effectiveness and safety of tofacitinib in moderate to severe UC patients.Methods:We searched the PubMed, EMBASE, Scopus, Web of Science and Cochrane databases for observational studies on the use of tofacitinib in UC patients, published between 30 May 2018 and 24 January 2021. Pooled induction (8–14 weeks) and maintenance (16–26 weeks) clinical response and remission rates were calculated, as well as the proportion of reported adverse events using random effects models.Results:Nine studies were included, comprising 830 patients, of which 81% were previously treated with anti-tumour necrosis factor (TNF) and 57% with vedolizumab. Induction of clinical response and remission were achieved in 51% (95% confidence interval, 41–60%) and 37% (26–45%) of patients, after a median follow-up of 8 weeks. At the end of a median follow-up of 24 weeks, maintenance of clinical response and remission were met in 40% (31–50%) and 29% (23–36%) of patients, respectively. Thirty-two percent of the patients had at least one adverse event, the most commonly reported being mild infection (13%) and worsening of UC, requiring colectomy (13%). A third of the patients (35%) discontinued tofacitinib, most frequently due to primary non-response (51%).Conclusion:Tofacitinib is a safe and effective therapy in real-world UC patients, as previously reported by clinical trials.

Early Changes in Serum Albumin Predict Clinical and Endoscopic Outcomes in Patients With Ulcerative Colitis Starting Anti-TNF Treatment.

Up to 60% of patients with ulcerative colitis (UC) ultimately fail anti-tumor necrosis factor (TNF) treatment. We aimed to investigate early predictive markers of clinical and endoscopic outcomes in patients with UC who were anti-TNF-naïve commencing anti-TNF treatment, with particular focus on changes in albumin and C-reactive protein levels in the first 2 weeks of treatment. We retrospectively investigated 210 patients with UC who started infliximab or adalimumab between 2009 and 2016 (male, 62.4%; median age at diagnosis, 37.9 years [interquartile range, 25.5-48.9 years]; median follow-up duration, 3.3 years [1.9-5.0 years]). Logistic and Cox proportional-hazards regressions were performed to identify variables associated with primary nonresponse (PNR), endoscopic outcomes, time-to-colectomy, and anti-TNF failure. Forty-one patients (19.5%) experienced PNR; week 0/week 2 ratio serum albumin was associated with PNR (adjusted odds ratio [aOR], 1.8; 95% confidence interval [CI], 1.1-2.9, per interquartile range increase). Week 0/week 2 ratio albumin was also associated with endoscopic response (aOR, 0.28; 95% CI, 0.31-0.82) and endoscopic remission (aOR, 0.61; 95% CI, 0.39-0.96) at weeks 8 to 14, time-to-colectomy (adjusted hazard ratio, 2.12; 95% CI, 1.29-3.49) and time-to-anti-TNF failure (adjusted hazard ratio, 1.54; 95% CI, 1.22-1.96), regardless of age, disease severity, or in-patient status. Association with time-to-colectomy and anti-TNF failure was externally validated in an independent cohort of inpatients with UC starting infliximab. Change in serum albumin within the first 2 weeks of anti-TNF treatment is predictive of PNR, endoscopic outcomes, time-to-colectomy, and anti-TNF failure in patients with UC. Timely access to this biomarker enables early identification of patients with UC at risk of anti-TNF failure and may guide early optimization of anti-TNF treatment to improve disease outcomes.

PGI10 Burden of Complex Perianal Fistulae in Patients with Crohn's Disease in Portugal

To estimate the burden of complex perianal fistulae (CPF) in adult patients with Crohn’s disease (CD) in Portugal mainland during 2017, using disability adjusted life years (DALY). The burden of disease follows a prevalence based approach. It was assumed that no deaths were due specifically to CPF in CD. Therefore only years lost due to disability (YLD) were estimated using a methodology in stages. First, a pharmacoepidemiological approach was used to estimate the prevalence of inflammatory bowel disease patients treated with biological agents, based on the latest national sales data. Second, the proportions of these with CD and, in this group, of those receiving anti-tumour necrosis factor treatment were used to estimate prevalent patients with CD. Finally, prevalence rates of CPF in CD were based on the literature. Next a cumulative incidence model of CPF in CD patients was used to estimate the prevalence in each disease state: active fistulae; fistulae closure; post successful surgery; post unsuccessful surgery. Disability weights per health state were based on utility values from cost-utility studies. In 2017, 3.080 CD patients had been previously diagnosed with CPF and 741 had an active CPF. With DALY solely based on YLD, the overall burden for 2017 was estimated at 996 DALY, of which 382 DALY were due to the active phase of the disease. The average burden per patient was estimated at 0.08 DALY per CD patient and at 0.52 DALY per patient with an active CPF in CD. In 2017, CPF-CD was responsible for a burden of 996 DALY, of which 382 are due to the active phase of the disease. Despite the low prevalence of CPF in CD, the burden of disease per patient is high. This reflects the importance of the disease and justifies further attention from healthcare decision makers.

Clinical Relevance of Anti-TNF Antibody Trough Levels and Anti-Drug Antibodies in Treating Inflammatory Bowel Disease Patients

Background and Aims: The majority of patients treated with anti-tumor necrosis factor (TNF) therapy develop anti-drug antibodies (ADAs), which might result in loss of treatment efficacy. Strict guidelines on measuring trough levels (TLs) and ADA in clinical routine do not exist. To provide real-world data, we took advantage of our tertiary inflammatory bowel disease (IBD) center patient cohort and determined indicators for therapeutic drug monitoring (TDM) and actual consequences in patient care. Methods: We retrospectively collected clinical data of 104 IBD patients treated with infliximab or adalimumab in our IBD clinic. Patients with TL and ADA measurements between June 2015 and February 2018 were included. Results: The main reason for determining TL was increased clinical disease. Subtherapeutic TLs were found in 33 patients, therapeutic TLs in 33 patients, and supratherapeutic TLs in 38 patients. Adjustments in anti-TNF therapy occurred more frequently (p = 0.01) in patients with subtherapeutic TL (24 of 33 patients; 73%) as compared to patients with therapeutic and supratherapeutic TLs (26 of 71 patients; 37%). No correlation could be found between TL and disease activity (p = 0.16). Presence of ADA was found in 16 patients, correlated with the development of infusion reactions (OR: 10.6, RR: 5.4, CI: 2.9–38.6), and was associated with subtherapeutic TL in 15 patients (93.8%). Treatment adaptations were based on TL and/or ADA presence in 36 of 63 patients. Conclusions: TDM showed significant treatment adaptations in patients with subtherapeutic TL. Conversely, in patients with therapeutic and supratherapeutic TLs, reasons for adaptations were based on considerations other than TL, such as clinical disease activity. Further studies should focus on decision-making in patients presenting with supratherapeutic TL in remission.

Mucosal microbiota and gene expression are associated with long-term remission after discontinuation of adalimumab in ulcerative colitis

Given that sustained remission is the ultimate treatment goal in the management of patients with ulcerative colitis (UC), the decision to stop anti-tumor necrosis factor (anti-TNF) treatment in UC patients is difficult. The aim of this study was to evaluate mucosal microbiota and gene expression profiles associated with long-term remission after discontinuation of anti-TNF therapy. In nine UC patients who received anti-TNF therapy for 6 months, microbiota isolated from uninflamed mucosae and gene expression in inflamed and uninflamed mucosae were investigated at week 0 and at week 24. At treatment initiation, Fusobacterium sp. and Veillonella dispar were over-represented in the relapse group compared with the non-relapse group. After treatment, Dorea sp. and Lachnospira sp. were over-represented in the non-relapse group. In the relapse group only, a significant shift in gut bacterial community composition was found between week 0 and week 24. Gene expression of ALIX (PDCD6IP) and SLC9A3 was significantly higher in the non-relapse group than in the relapse group. Lastly, we used machine learning methods to identify relevant gene signatures associated with sustained remission. Statistical analyses of microbiota and expression profiles revealed differences between UC patients who did or did not keep remission after the discontinuation of TNF inhibitors.Trial registration: UMIN000020785: Evaluation of adalimumab therapy in mesalazine-resistant or -intolerant ulcerative colitis; an observational study (EARLY study).

Impact of Secukinumab on Patient-Reported Outcomes in the Treatment of Ankylosing Spondylitis: Current Perspectives.

Ankylosing spondylitis (AS) is a chronic rheumatic disease involving inflammation of the joints and spine, which carries a substantial, life-long burden for the patient. Secukinumab is a fully human anti-interleukin-17A monoclonal antibody, approved in the USA and EU for the treatment of AS. In this narrative review, we searched PubMed with the aim of consolidating the recent literature regarding the impact of secukinumab on patient-reported outcomes in patients with AS. A large clinical trial program has demonstrated the efficacy of secukinumab in relieving the signs and symptoms of AS. Most importantly from a patient perspective, secukinumab has produced improvements in a range of patient-reported outcomes (PROs), including pain, fatigue, quality of life and work productivity, as well as composite measures including patient-reported elements, such as the Bath indices and Assessment of SpondyloArthritis international Society (ASAS) response criteria. Benefits to patients were rapid, and sustained in the long term (up to 5 years). The positive effect of secukinumab was seen regardless of whether patients had previously been treated with anti-tumor necrosis factor (TNF) therapies. Greater improvements in PROs were associated with patients being anti-TNF-naïve, of a younger age, with shorter disease duration and higher objective measures of inflammation at baseline. The available real-world evidence suggests that the effects of secukinumab on PROs in clinical practice are consistent with those seen in clinical trials, and evidence in a real-world setting continues to be collected.

Changes in Patient Reported Pain Measures With the Citrate-free Adalimumab Formulation in Pediatric Inflammatory Bowel Disease Patients

Inflammatory bowel diseases (IBD) are characterized by chronic inflammation in the gastrointestinal tract. The perception of pain in children is very complex and involves psychological, physiological, behavioral, and developmental factors. For children with chronic diseases, the medical procedures and treatments are often painful, unexpected, and heightened by situational stress and anxiety leading to an overall unpleasant experience. Pain and injection-site reaction are major predictors of nonadherence to antitumor necrosis factor treatment. The most commonly reported adalimumab adverse event was injection-site reaction. This study compares reported pain in pediatric IBD patients between the 2 formulations using a visual analog scale (VAS). Our hypothesis is that the citrate-free formulation would have significantly less injection-site pain than the original formulation. We evaluated injection-site pain in 6- to 17-year olds with IBD between the original formulation and citrate-free using the Faces Pain Scale-Revised for pain from 0 (no pain) to 10 (worse pain possible). Ninety-five percent of patients reported that their pain score was greater than 3 with original formulation, while only 5% of them reported their pain score was greater than 3 with citrate free. The McNemar’s test showed significant difference in the pain score between the 2 types of injection (P &lt; 0.0001).

Anti-tumor necrosis factor drug responses and skin-blood DNA methylation age: Relationships in moderate-to-severe psoriasis.

Studies have examined the utility of DNA methylation as a biomarker of psoriasis treatment responses, but investigations of treatment responses with Skin-Blood DNA methylation age (SkinBloodAge)-a methylation-based measure of health designed using skin tissues-are lacking. Using a HumanMethylation450 BeadChip blood DNA methylation data set from 70 white patients who presented with moderate-to-severe plaque psoriasis and were treated with anti-tumor necrosis factor (TNF) agents in Madrid, Spain, we examined the cross-sectional relationships of SkinBloodAge with anti-TNF treatment responses. Partial responders had a 7.2-year higher mean SkinBloodAge than excellent responders (P=.03). In linear regression models adjusted for chronological age, sex and anti-TNF agents - on average - partial responders had a 2.65-year higher SkinBloodAge than excellent responders (95%CI: 0.44, 4.86, P=.02). This relationship was attenuated in a sensitivity analysis adjusting for white blood cells including known T-cell mediators of psoriasis pathophysiology (β=1.91-years, 95%CI: -0.50, 4.32, P=.12). Overall, our study suggests that partial responders to anti-TNF therapy have higher SkinBloodAges when compared to excellent responders. Although these findings still need to be confirmed more broadly, they further suggest that SkinBloodAge may be a useful treatment response biomarker that can be incorporated with other blood tests before anti-TNF therapy initiation in moderate-to-severe psoriasis patients.

Efficacy and safety of treatment with anti‐tumor necrosis factor‐α drugs for severe impetigo herpetiformis

Impetigo herpetiformis (IH) is a rare pustular dermatosis. It can be life-threatening for both the mother and fetus and often causes therapeutic problems. However, there is no specific guideline for the treatment of IH and the evidence regarding the efficacy of treatments for IH has not been established. Herein, we report two cases of IH, which were successfully treated with anti-tumor necrosis factor (TNF)-α drugs. The serum levels of the drugs in the infants and mothers were examined using enzyme-linked immunosorbent assay (ELISA). Case 1 was a 35-year-old, gravida 2, para 1, female patient in week 20 of pregnancy; she was treated with adalimumab (ADA) until delivery. Case 2 was a 26-year-old, gravida 1, para 0, female patient in week 30 of pregnancy; she was treated with certolizumab pegol (CZP) until delivery. In both cases, the skin lesions started regressing considerably after administration of the biologic agents. We examined the serum levels of the biologic agents in the mothers and infants using ELISA. In case 1, the ADA serum level in the infant was as high as that in the mother at birth; it then decreased below the lower limit of quantification at week 12 post-delivery. In case 2, the CZP serum level in the infant was below the lower limit of quantification at birth. In this report, we revealed that biologic agents could be an effective treatment for severe IH and that CZP treatment can be considered safe for the mothers and fetuses.

Factors Associated with the Immunogenicity of Anti-Tumor Necrosis Factor Agents in Pediatric Patients with Inflammatory Bowel Disease.

Background/AimsAnti-drug antibodies (ADAs) can develop during treatment with anti-tumor necrosis factor (TNF) agents. We aimed to investigate the factors associated with immunogenicity of anti-TNF agents in pediatric patients with inflammatory bowel disease (IBD) and observe the clinical course of ADA-positive patients.MethodsPediatric IBD patients receiving maintenance treatment with anti-TNF agents who had been tested for ADAs against infliximab (IFX) or adalimumab (ADL) were included in this cross-sectional study. Factors associated with ADA positivity were investigated by analyzing clinicodemographic, laboratory, and treatment-related factors.ResultsA total of 76 patients (Crohn’s disease, 65; ulcerative colitis, 11) were included. Among these, 59 and 17 patients were receiving IFX and ADL, respectively. ADAs were found in 10 patients (13.2%), all of whom were receiving IFX. According to multivariable logistic regression analysis, the IFX trough level (TL) was associated with ADA positivity (odds ratio, 0.25; 95% confidence interval [CI], 0.08 to 0.51; p=0.002). According to the receiver operating characteristic analysis, the optimal cutoff of the IFX TLs for stratifying patients based on the presence of ADAs against IFX was 1.88 μg/mL (area under curve, 0.941; 95% CI, 0.873 to 1.000; sensitivity, 80.0%; specificity, 95.9%; p<0.001). Among the 10 patients with ADAs against IFX, five patients (50%) switched to ADL within 1 year, while five patients (50%) kept receiving IFX. Transient ADAs were observed in three patients (30%).ConclusionsIFX TL was the only factor associated with ADA formation in pediatric IBD patients receiving IFX. Future studies based on serial and proactive therapeutic drug monitoring are required in the future.

Dissecting Common and Unique Effects of Anti-α4β7 and Anti-Tumor Necrosis Factor Treatment in Ulcerative Colitis.

Background and AimsVedolizumab is an anti-α4β7 antibody approved for the treatment of ulcerative colitis [UC]. Although it is assumed that vedolizumab blocks intestinal homing of lymphocytes, its effects on different intestinal cell populations are not fully stablished. In order to establish the unique mechanisms of action of vedolizumab in UC patients, we compared its effects to those induced by anti-tumour necrosis factor [TNF].MethodsPatients with active UC [endoscopic Mayo score >1] starting vedolizumab [n = 33] or anti-TNF [n = 45] and controls [n = 22] were included. Colon biopsies [at weeks 0, 14 and 46] and blood samples [at weeks 0, 2, 6, 14, 30 and 46] were used for cell phenotyping, transcriptional analysis [qPCR], and to measure receptor occupancy.ResultsVedolizumab, in contrast to anti-TNF, significantly reduced the proportion of α4β7+ cells within intestinal T subsets while preserving the percentage of α4β7+ plasma cells. The marked decrease in α4β7 did not change the percentage of colonic αEβ7+ cells [at 46 weeks]. Both vedolizumab and anti-TNF significantly downregulated inflammation-related genes in the colon of responders [Mayo score < 2]. Moreover, both treatments significantly decreased the percentage of intestinal, but not blood, total lymphocytes [T and plasma cells], as well as the proportion of α4β1+ cells within intestinal T lymphocytes.ConclusionsOur data show that while vedolizumab and anti-TNF block two unrelated targets, they induce remarkably similar effects. On the other hand, vedolizumab’s unique mechanism of action relies on blocking intestinal trafficking of α4β7 T cells, despite effectively binding to B and plasma cells that express α4β7.

Ulcerative colitis.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease of unknown aetiology affecting the colon and rectum. Multiple factors, such as genetic background, environmental and luminal factors, and mucosal immune dysregulation, have been suggested to contribute to UC pathogenesis. UC has evolved into a global burden given its high incidence in developed countries and the substantial increase in incidence in developing countries. An improved understanding of the mechanisms underlying UC has led to the emergence of new treatments. Since the early 2000s, anti-tumour necrosis factor (TNF) treatment has significantly improved treatment outcomes. Advances in medical treatments have enabled a paradigm shift in treatment goals from symptomatic relief to endoscopic and histological healing to achieve better long-term outcomes and, consequently, diagnostic modalities have also been improved to monitor disease activity more tightly. Despite these improvements in patient care, a substantial proportion of patients, for example, those who are refractory to medical treatment or those who develop colitis-associated colorectal dysplasia or cancer, still require restorative proctocolectomy. The development of novel drugs and improvement of the treatment strategy by implementing personalized medicine are warranted to achieve optimal disease control. However, delineating the aetiology of UC is necessary to ultimately achieve disease cure.

Optimizing biologic therapy in IBD: how essential is therapeutic drug monitoring?

Proposed treatment targets for the management of inflammatory bowel disease (IBD) have moved beyond symptomatic improvement towards more objective end points, such as healing of the intestinal mucosa. This treat-to-target approach has been associated with improved disease outcomes such as diminished bowel damage, surgery and hospitalizations. Many patients with IBD require biologic therapy to achieve and maintain clinical and endoscopic remission, and antitumour necrosis factor antibodies remain the first-line biologic therapy in most areas of the world. Unfortunately, up to one-third of patients receiving this treatment are primary non-responders, and some patients that show an initial response can also lose response over time. Therapeutic drug monitoring (TDM) has been suggested as a useful tool to manage patients on antitumour necrosis factor treatment, including monitoring for dose escalation, de-escalation or to switch treatment. In this Perspective, we aim to summarize evidence and guidelines related to TDM in IBD management and also discuss potential strategies to optimize biologic treatment where TDM is not available.

Type I and II Interferon Signatures Can Predict the Response to Anti-TNF Agents in Inflammatory Bowel Disease Patients: Involvement of the Microbiota.

Anti-TNF agents have been a cornerstone of IBD therapy; however, response to treatment has been variable, and clinically applicable biomarkers are urgently needed. We hypothesized that the type I and type II interferon (IFN) signatures may be a confounding factor for response to antitumor necrosis factor (TNF) treatment via interactions with the host and its gut microbiota. Peripheral blood from 30 IBD patients and 10 healthy controls was subjected to real-time quantitative real-time polymerase chain reaction for type I and type II IFN genes (IFNGs), both at baseline and after treatment with anti-TNF. Correlation between IFN signatures and microbiota composition was also determined for a subgroup of patients and controls. At baseline, type I IFN score was significantly higher in IBD patients (P = 0.04 vs controls). Responders to subsequent anti-TNF treatment had significantly lower baseline scores for both type I and II IFN signatures (P < 0.005 vs nonresponders for both comparisons). During treatment with anti-TNF, the expression of type I and II IFNGs was significantly elevated in responders and decreased in nonresponders. In addition, changes in IFN signatures correlated to specific alterations in the abundance of several microbial taxa of the gut microbiome. Baseline expression of type I and II IFN signatures and their kinetics during anti-TNF administration significantly correlate to treatment responses in IBD patients. Peripheral blood IFN signatures may serve as clinically meaningful biomarkers for the identification of subgroups of patients with favorable response to anti-TNF treatment. Additionally, the distinct synergies between different IFN types and microbiota might help drive therapeutic intervention.

Investigation of genetically regulated gene expression and response to treatment in rheumatoid arthritis highlights an association between IL18RAP expression and treatment response

ObjectivesIn this study, we sought to investigate whether there was any association between genetically regulated gene expression (as predicted using various reference panels) and anti-tumour necrosis factor (anti-TNF) treatment response...

Hip and Shoulder Involvement and Their Management in Axial Spondyloarthritis: a Current Review

Hip and shoulder disease can occur in patients with spondyloarthritis (SpA). While hip involvement has been widely assessed in axial SpA patients, studies in the overall SpA population as well as studies focused on shoulder involvement are scarce. Here, we review the most recent studies on the epidemiology, evaluation, and treatment of root joint involvement in SpA patients. Radiological hip involvement can affect up to 25% of patients with SpA, reflecting more severe disease and associated with functional impairment. Shoulder involvement in SpA patients is characterized by cuff tendinitis and enthesitis, while primary glenohumeral joint involvement is rare. Anti-tumor necrosis factor (anti-TNF) treatment in SpA patients seems to have an effect on hip arthritis, showing a change in trend in the frequency of hip replacement in this population. The majority of studies evaluating hip involvement have focused on axial SpA patients, but further studies evaluating root joint involvement in the overall SpA population are needed. Anti-TNF therapy should be considered in patients with hip involvement, and root joint involvement should be assessed routinely in clinical practice.

Correlation of patient preferences to treatment outcomes in patients with rheumatoid arthritis treated with tumour necrosis factor inhibitors in Greece.

To investigate possible associations between rheumatoid arthritis (RA) patient-expressed preferences over anti-tumour necrosis factor (anti-TNF) treatment and clinical and patient-reported outcomes. PANORAMA was a non-interventional, prospective, multicentre, cohort study of 12months duration, in patients with moderate-to-severe RA who initiated or switched to anti-TNF treatment. After initiation of anti-TNF, patients completed a preferences questionnaire on attributes related to anti-TNF treatment. Satisfaction with treatment was assessed with the Treatment Satisfaction Questionnaire for Medication (TSQM); compliance and persistence to treatment were recorded via a patient diary. Univariate and multivariate analyses were applied to assess correlations between patients' preferences over treatment with clinical and patient-reported outcomes. A total of 254 patients were enrolled; 66.1% (168/254) had highly active disease (DAS28-ESR > 5.1), while 65.4% (166/254) were biological-naïve. The 12-month drug-survival rate was 72.3%, while the respective rates of good EULAR response and remission (DAS28-ESR < 2.6) were 56.5% and 40.8%, respectively. By univariate analysis, fulfilment of patient preferences over treatment was associated with increased probability of remaining on therapy (p = 0.019), good EULAR response (p < 0.001) and satisfaction with treatment (p < 0.001). By multivariate analysis, fulfilment of patient preferences was the most important predictor for good EULAR response (OR 5.56, p < 0.001; finding confirmed and after propensity scoring matching), while seropositivity (HR 1.18, p = 0.047) and a high ESR (> 35mm/h, HR 1.16, p = 0.071) predicted drug survival. In anti-TNF-treated RA patients, fulfilment of treatment preferences was independently associated with a good EULAR response and correlated with drug persistence at 12months, emphasising the importance of patient preferences in treatment outcomes. Key Points • In anti-TNF treated RA patients, fulfilment of patients' treatment preferences is associated with a good clinical response at 12months. • A shared decision-making process can maximise treatment's outcome in anti-TNF treated patients.
