Safety Profile of Upadacitinib up to 5 Years in Psoriatic Arthritis, Ankylosing Spondylitis, and Non-radiographic Axial Spondyloarthritis: An Integrated Analysis of Clinical Trials. Rheumatol Ther 2024; 11:737-753. [PMID: 38683479 PMCID: PMC11111431 DOI: 10.1007/s40744-024-00671-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 04/02/2024] [Indexed: 05/01/2024] Open
Abstract
INTRODUCTION This integrated analysis of the phase 2/3 and phase 3 SELECT trials describes the safety profile of upadacitinib, an oral Janus kinase inhibitor, for up to 5 years of exposure across psoriatic arthritis (PsA), ankylosing spondylitis (AS), and non-radiographic axial spondyloarthritis (nr-axSpA) (including pooled axial spondyloarthritis [axSpA]). METHODS Safety data from five trials of upadacitinib in PsA (2 trials), AS (2 trials), and nr-axSpA (1 trial) were analyzed up to a data cut-off of August 15, 2022. One PsA study included adalimumab as an active comparator. Treatment-emergent adverse events (TEAEs) were summarized for PsA (pooled upadacitinib 15 mg once daily and adalimumab 40 mg biweekly), AS (pooled upadacitinib 15 mg), nr-axSpA (upadacitinib 15 mg), and pooled axSpA (pooled upadacitinib 15 mg from axSpA trials). TEAEs were reported as exposure-adjusted event rates per 100 patient-years (E/100 PY). RESULTS A total of 1789 patients (PsA, n = 907; AS, n = 596; nr-axSpA, n = 286) received ≥ 1 dose of upadacitinib 15 mg for 3689 PY of exposure or adalimumab (n = 429) for 1147 PY of exposure. Overall TEAEs and serious TEAEs were highest in PsA and numerically higher with upadacitinib versus adalimumab; rates were similar between AS and nr-axSpA. In PsA, higher rates of serious infection, herpes zoster (HZ), lymphopenia, and nonmelanoma skin cancer (NMSC) were observed with upadacitinib versus adalimumab. Rates of malignancy excluding NMSC, adjudicated major adverse cardiovascular events, and adjudicated venous thromboembolic events were comparable between upadacitinib and adalimumab in PsA and were similar across diseases. CONCLUSION Higher rates of serious infection, HZ, lymphopenia, and NMSC were observed with upadacitinib versus adalimumab in PsA; slightly elevated rates for most of these TEAEs were seen with upadacitinib in PsA versus axSpA. Upadacitinib 15 mg demonstrated a generally consistent safety profile across disease states with no new safety signals identified. TRIAL REGISTRATION SELECT-AXIS 1: NCT03178487; SELECT-AXIS 2: NCT04169373; SELECT-PsA 1: NCT03104400; SELECT-PsA 2: NCT03104374.

Identifying and Quantifying the Role of Inflammation in Pain Reduction for Patients With Psoriatic Arthritis Treated With Tofacitinib: A Mediation Analysis. Rheumatol Ther 2022; 9:1451-1464. [PMID: 36076054 PMCID: PMC9510078 DOI: 10.1007/s40744-022-00482-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 08/01/2022] [Indexed: 11/26/2022] Open
Abstract
INTRODUCTION Pain is a multidimensional factor and core domain of psoriatic arthritis (PsA). This analysis aimed to quantify the role of potential inflammation-associated outcomes on pain reduction in patients with PsA receiving tofacitinib, using mediation modeling. METHODS Pooled data were from two phase 3 studies (OPAL Broaden and OPAL Beyond) of patients with active PsA treated with tofacitinib 5 mg twice daily or placebo. Mediation modeling was utilized to quantify the indirect effects (via Itch Severity Item [ISI], C-reactive protein [CRP] levels, swollen joint count [SJC], Psoriasis Area and Severity Index [PASI], and enthesitis [using Leeds Enthesitis Index]) and direct effects (representing all other factors) of tofacitinib treatment on pain improvement. RESULTS The initial model showed that tofacitinib treatment affects pain, primarily indirectly, via ISI, CRP, SJC, PASI, and enthesitis (overall 84.0%; P = 0.0009), with 16.0% (P = 0.5274) attributable to the direct effect. The model was respecified to exclude SJC and PASI. Analysis of the final model revealed that 29.5% (P = 0.0579) of tofacitinib treatment effect on pain was attributable to the direct effect, and 70.5% (P < 0.0001) was attributable to the indirect effect. ISI, CRP, and enthesitis mediated 37.4% (P = 0.0002), 15.3% (P = 0.0107), and 17.8% (P = 0.0157) of the tofacitinib treatment effect on pain, respectively. CONCLUSIONS The majority of the effect of tofacitinib on pain was collectively mediated by itch, CRP, and enthesitis, with itch being the primary mediator of treatment effect.

Frequency and Duration of Early Non-serious Adverse Events in Patients with Rheumatoid Arthritis and Psoriatic Arthritis Treated with Tofacitinib. Rheumatol Ther 2022; 9:411-433. [PMID: 34921355 PMCID: PMC8964869 DOI: 10.1007/s40744-021-00405-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Accepted: 11/17/2021] [Indexed: 11/07/2022] Open
Abstract
INTRODUCTION Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA) and psoriatic arthritis (PsA). This post hoc analysis assessed frequency or duration of early select non-serious adverse events (AEs; excluding infections), and their impact on treatment discontinuation, in patients with RA or PsA treated with tofacitinib 5 or 10 mg twice daily, or placebo. METHODS Data were pooled from five phase 3 and one phase 3b/4 studies in patients with moderate-to-severe RA, and two phase 3 studies in patients with active PsA. Select all-causality, non-serious AEs, reported to month 3 (placebo-controlled period), were headache, diarrhea, nausea, vomiting, and gastric discomfort (including dyspepsia, gastritis, epigastric discomfort, and abdominal discomfort or pain); incidence rates (unique patients with events per 100 patient-years of follow-up), duration of, and discontinuations due to these non-serious AEs were reported. RESULTS We analyzed 3871 and 710 patients with RA and PsA, respectively. Incidence of non-serious AEs to month 3 was generally similar with tofacitinib and placebo. The most frequent non-serious AEs were headache and diarrhea with tofacitinib, and dyspepsia, nausea, and headache with placebo. Most events were mild or moderate in severity, lasting ≤ 4 weeks. Permanent discontinuations due to non-serious AEs were not observed in patients with PsA, and were < 1.0% in patients with RA across treatment groups. The most frequent cause of temporary discontinuation across all groups was gastric discomfort (0.3-0.8%). CONCLUSIONS Non-serious AE incidence was generally similar in patients with RA or PsA receiving tofacitinib or placebo. Most events were mild or moderate and generally resolved within 4 weeks.

Abstract
The pathogenesis of psoriasis, an immune-mediated chronic inflammatory skin disease, remains unclear. Studies have shown an association between psoriasis and intestinal inflammation; in this context, the influence of the gut microbiota on the immune response of psoriasis has become a focus of recent research. The present research evaluated the composition and diversity of the gut microbiota of 21 participants with psoriasis from a Brazilian referral dermatology service compared to 24 healthy controls. A stool sample was collected from each participant at the time of inclusion in the study, and the samples were analysed by sequencing the 16S rRNA gene. The recruitment of research participants involved matching between groups by sex, age, body mass index, comorbidities and smoking and the exclusion of several criteria that could potentially influence the gut microbiota and the interpretation of the data. There was an increase in the Dialister genus and Prevotella copri species in patients with psoriasis compared to the control group. A reduction in the Ruminococcus, Lachnospira and Blautia genera, as well as in the Akkermansia muciniphila species, was also verified in the psoriasis group compared to the control group. Furthermore, patients with psoriasis exhibited less gut microbiota diversity than controls.

Exploring the Quality of Communication Between Patients with Psoriatic Arthritis and Physicians: Results of a Global Online Survey. Rheumatol Ther 2021; 8:1741-1758. [PMID: 34570345 PMCID: PMC8572306 DOI: 10.1007/s40744-021-00367-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 08/26/2021] [Indexed: 11/28/2022] Open
Abstract
INTRODUCTION Effective communication between patients with psoriatic arthritis (PsA) and their physicians is important for optimizing treatment outcomes. We assessed the quality of patient-physician communication in terms of awareness and impact of PsA symptoms, their levels of satisfaction, and their perceptions of communications. METHODS A global online survey was conducted by The Harris Poll in adult patients with PsA and physicians managing patients with PsA in eight countries. Participating physicians were either rheumatologists or dermatologists seeing ≥ 10 and ≥ 5 patients with PsA per month, respectively. Patient and physician groups were unmatched. Patient-physician communication was assessed with 35-60 questions regarding discussion topics during consultations, levels of satisfaction with communication, and specific communication issues. RESULTS A total of 1286 patients with PsA (983 and 303 whose primary treating physician was a rheumatologist or dermatologist, respectively) and 1553 physicians (795 rheumatologists and 758 dermatologists) completed the survey. Regardless of whether they were primarily treated by a rheumatologist or dermatologist, most patients reported a social (84% and 81%, respectively) or work (81% and 80%, respectively) impact of PsA, and a major/moderate negative impact on their physical activity levels (79% and 74%, respectively) or emotional/mental wellbeing (69% and 68%, respectively). Physician responses were generally consistent with this; however, physicians often appeared to under-recognize the extent to which PsA affects patients. Most (≥ 85%) patients and physicians were very/somewhat satisfied with their patient-physician communication, and most (≥ 86%) patients were comfortable raising their concerns/fears with their physician. However, > 40% of patients were identified as being at risk of suboptimal communication. These patients were significantly less likely to report their PsA symptoms even when asked, were less comfortable discussing the impacts of PsA with their physician, and were more likely to experience major/moderate impacts of PsA on their health-related quality of life (HRQoL). CONCLUSIONS Physicians often underestimate the impacts of PsA, compared with patients, and some patients may be at risk of suboptimal communication with their attending physician, which may worsen the HRQoL impacts of PsA. These findings highlight a need for ways to improve communication between patients with PsA and their healthcare providers.

Efficacy and safety of tofacitinib by background methotrexate dose in psoriatic arthritis: post hoc exploratory analysis from two phase III trials. Clin Rheumatol 2021; 41:499-511. [PMID: 34510295 PMCID: PMC8782818 DOI: 10.1007/s10067-021-05894-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 08/23/2021] [Accepted: 08/24/2021] [Indexed: 11/05/2022]
Abstract
Objective Analyze tofacitinib efficacy and safety by background methotrexate (MTX) dose in patients with psoriatic arthritis (PsA). Methods This post hoc analysis pooled data from two phase III, double-blind trials (OPAL Broaden, NCT01877668; OPAL Beyond, NCT01882439) including patients receiving tofacitinib 5 or 10 mg twice daily (BID), or placebo, with stable MTX. Efficacy outcomes at month 3 stratified by MTX dose (≤ 15 month 3 stratified by MTX dose vs > 15 mg/week) were American College of Rheumatology (ACR)20/50/70, Health Assessment Questionnaire-Disability Index (HAQ-DI); Psoriasis Area and Severity Index (PASI)50/75; change from baseline in HAQ-DI; physician’s global assessment of PsA (PGA-PsA-visual analog scale [VAS]); patient’s global joint and skin assessment (PGJS-VAS), Leeds Enthesitis Index (LEI); and Dactylitis Severity Score (DSS). Safety assessments included adverse events and laboratory parameters. Results Five hundred fifty-six patients received tofacitinib 5 mg BID (n = 186), 10 mg BID (n = 178), or placebo (n = 192), plus MTX (≤ 15 mg/week, n = 371; > 15 mg/week, n = 185). At month 3, tofacitinib efficacy was generally greater than placebo. Patients receiving tofacitinib 5 mg BID demonstrated greater numerical improvements in efficacy outcomes at month 3 with MTX > 15 mg/week vs MTX ≤ 15 mg/week; patients receiving tofacitinib 10 mg BID displayed the opposite. The safety profile was generally consistent between groups; headache was associated with MTX > 15 mg/week; decreased hemoglobin levels were observed in patients receiving tofacitinib 10 mg BID and MTX ≤ 15 mg/week. Conclusion Efficacy of tofacitinib was generally numerically greater than placebo, regardless of MTX dose. Tofacitinib 5 mg BID was generally more efficacious with MTX > 15 mg/week vs ≤ 15 mg/week; the opposite was observed for tofacitinib 10 mg BID. Headache was more frequent with MTX > 15 mg/week. Trial registration ClinicalTrials.gov. Identifier: NCT01877668 (registration: June 14, 2013) and NCT01882439 (registration: June 20, 2013).Key Points • Methotrexate is widely used in the treatment of psoriatic arthritis; however, there are limited data on the impact of varying background methotrexate doses on the efficacy and safety of Janus kinase inhibitors in patients with psoriatic arthritis. • This post hoc analysis assessed the impact of background methotrexate dose (≤ 15 or > 15 mg/week) on tofacitinib efficacy and safety in patients with psoriatic arthritis. • Results indicated that tofacitinib efficacy was generally numerically greater than placebo, regardless of methotrexate dose. Tofacitinib 5 mg twice daily, in combination with a higher dose of background methotrexate, was more efficacious compared with a lower dose of background methotrexate; the opposite was observed for tofacitinib 10 mg twice daily. • Headache was more frequent with the higher methotrexate dose. Data should be interpreted with caution due to the small sample sizes. |

Prevalence, demographics, and clinical characteristics of Latin American patients with spondyloarthritis. Adv Rheumatol 2021; 61:2. [PMID: 33419481 DOI: 10.1186/s42358-020-00161-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 12/30/2020] [Indexed: 01/19/2023] Open
Abstract
Large epidemiologic and clinical estimates of spondyloarthritis (SpA) in Latin America are not available. In this narrative review, our goal was to descriptively summarize the prevalence and features of SpA in Latin America, based on available small studies. A review of peer-reviewed literature identified 41 relevant publications. Of these, 11 (mostly based on Mexican data) estimated the prevalence of SpA and its subtypes, which varied from 0.28 to 0.9% (SpA), 0.02 to 0.8% (ankylosing spondylitis), 0.2 to 0.9% (axial SpA), and 0.004 to 0.08% (psoriatic arthritis). Demographic and/or clinical characteristics were reported in 31 of the 41 publications, deriving data from 3 multinational studies, as well as individual studies from Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, Peru, Uruguay, and Venezuela. Data relating to treatment, disease manifestations (articular and extra-articular), and comorbidities were summarized across the countries. Available data suggest that there is a variability in prevalence, manifestations, and comorbidities of SpA across Latin America. Basic epidemiologic and clinical data are required from several countries not currently represented. Data relating to current treatment approaches, patient outcomes, and socioeconomic impact within this large geographic region are also needed.

Results of a global, patient-based survey assessing the impact of psoriatic arthritis discussed in the context of the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire. Health Qual Life Outcomes 2020; 18:173. [PMID: 32513190 PMCID: PMC7282161 DOI: 10.1186/s12955-020-01422-z] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 05/26/2020] [Indexed: 12/14/2022] Open
Abstract
Background Psoriatic arthritis (PsA) is a chronic immune-mediated inflammatory musculoskeletal disease, manifesting as peripheral arthritis, enthesitis, dactylitis, spondylitis, and skin and nail psoriasis. A core set of domains for measuring the impact of PsA has been developed, including pain, patient global assessment, physical function, health-related quality of life (HRQoL), and fatigue. To understand the impact of PsA on health domains from a patient’s perspective, a global survey was developed and results reported in the context of the 12-item Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire. Methods An online patient-based global survey was conducted by The Harris Poll in Australia, Brazil, Canada, France, Spain, Taiwan, the UK, and the US between November 2, 2017 and March 12, 2018. Eligible patients were ≥ 18 years old with a diagnosis of PsA for > 1 year, had visited a rheumatologist/dermatologist in the past 12 months and reported using ≥ 1 synthetic/biologic disease-modifying antirheumatic drug for PsA. Patients reported on PsA severity and symptoms, and the impact of PsA on HRQoL. After survey completion, responses were aligned with PsAID health domains. Descriptive statistics and chi-square tests were conducted. Results This analysis included 1286 patients from eight countries. Most patients (97%) reported musculoskeletal symptoms relating to PsA in the past year. Common moderate/major impacts of PsA were on physical activity (78%), ability to perform certain activities (76%), work productivity (62%), and career path (57%). Skin/nail symptoms occurred in 80% of patients. Overall, 69% of patients reported that PsA had a moderate/major impact on emotional/mental wellbeing, 56% on romantic relationships/intimacy, and 44% on relationships with family and friends. Social impacts included emotional distress (58%), social shame or disapproval (32%), and ceased participation in social activities (45%). Over half of all patients experienced unusual fatigue over the past 12 months (52%). The health domains that patients reported as being impacted by PsA aligned with life impact domains of the patient-derived PsAID health domains. Conclusion These results highlight the impact of PsA on multiple health domains from a patient perspective that should be considered during shared decision-making processes between healthcare providers and patients.

Abstract
INTRODUCTION Tofacitinib is an oral Janus kinase inhibitor for the treatment of psoriatic arthritis (PsA). OBJECTIVE Our objective was to compare the incidence rates (IRs) of adverse events in tofacitinib clinical trials and real-world observational data for alternative treatments. METHODS The tofacitinib "dose-comparison cohort" included months 0-12 of two phase III studies (tofacitinib 5 [n = 238] and 10 [n = 236] mg twice daily [BID]); the "all-tofacitinib comparison cohort" (n = 783) included two phase III and one ongoing long-term extension study (data cutoff May 2016). An "observational comparison cohort" (n = 5799) comprised patients initiating a conventional synthetic disease-modifying antirheumatic drug (DMARD), biologic DMARD, or apremilast in the US Truven MarketScan database from 2010 to 2015. IRs for serious infections (SIEs; requiring hospitalization), herpes zoster (HZ), malignancies (excluding non-melanoma skin cancer [NMSC]), NMSC, and major adverse cardiovascular events (MACE) across cohorts were qualitatively compared. RESULTS IRs (patients with events/100 patient-years) for SIEs were similar between the tofacitinib dose-comparison cohort (5 mg BID: 1.3; 10 mg BID: 2.0) and the observational comparison cohort (1.1-7.9; treatment dependent). The tofacitinib dose-comparison cohort had a higher rate of HZ (5 mg BID: 2.0; 10 mg BID: 2.7) than did the observational comparison cohort (0.8-2.0). IRs for NMSC were generally lower in the all-tofacitinib comparison cohort (0.5) than in the observational comparison cohort (0.4-6.0). IRs for MACE, malignancies excluding NMSC, and NMSC were similar between cohorts. CONCLUSION In patients with PsA, tofacitinib had a safety profile similar to that of other systemic therapies in real-world settings, except for the risk of HZ, a known risk of tofacitinib.

TNF-α-induced protein 3 (TNFAIP3)/A20 acts as a master switch in TNF-α blockade-driven IL-17A expression. J Allergy Clin Immunol 2017; 142:517-529. [PMID: 29248493 DOI: 10.1016/j.jaci.2017.11.024] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Revised: 10/21/2017] [Accepted: 11/06/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND Anti-TNF inhibitors successfully improve the quality of life of patients with inflammatory disease. Unfortunately, not all patients respond to anti-TNF therapy, and some patients show paradoxical immune side effects, which are poorly understood. Surprisingly, anti-TNF agents were shown to promote IL-17A production with as yet unknown clinical implications. OBJECTIVE We sought to investigate the molecular mechanism underlying anti-TNF-driven IL-17A expression and the clinical implications of this phenomenon. METHODS Fluorescence-activated cell sorting, RNA sequencing, quantitative real-time PCR, Western blotting, small interfering RNA interference, and kinase inhibitors were used to study the molecular mechanisms in isolated human CD4+ T cells from healthy donors. The clinical implication was studied in blood samples of patients with inflammatory bowel disease (IBD) receiving anti-TNF therapy. RESULTS Here we show that anti-TNF treatment results in inhibition of the anti-inflammatory molecule TNF-α-induced protein 3 (TNFAIP3)/A20 in memory CD4+ T cells. We found an inverse relationship between TNFAIP3/A20 expression levels and IL-17A production. Inhibition of TNFAIP3/A20 promotes kinase activity of p38 mitogen-activated protein kinase and protein kinase C, which drives IL-17A expression. Regulation of TNFAIP3/A20 expression and cognate IL-17A production in T cells are specifically mediated through TNF receptor 2 signaling. Ex vivo, in patients with IBD treated with anti-TNF, we found further evidence for an inverse relationship between TNFAIP3/A20 expression levels and IL-17A-producing T cells. CONCLUSION Anti-TNF treatment interferes in the TNFAIP3/A20-mediated anti-inflammatory feedback loop in CD4+ T cells and promotes kinase activity. This puts TNFAIP3/A20, combined with IL-17A expression, on the map as a potential tool for predicting therapy responsiveness or side effects of anti-TNF therapy. Moreover, it provides novel targets related to TNFAIP3/A20 activity for superior therapeutic regimens in patients with IBD.

Abstract
BACKGROUND Tofacitinib is an oral Janus kinase inhibitor that is under investigation for the treatment of psoriatic arthritis. We evaluated tofacitinib in patients with active psoriatic arthritis who had previously had an inadequate response to tumor necrosis factor (TNF) inhibitors. METHODS In this 6-month randomized, placebo-controlled, double-blind, phase 3 trial, we randomly assigned 395 patients, in a 2:2:1:1 ratio, to four regimens: 5 mg of tofacitinib administered orally twice daily (132 patients); 10 mg of tofacitinib twice daily (132 patients); placebo, with a switch to 5 mg of tofacitinib twice daily at 3 months (66 patients); or placebo, with a switch to 10 mg of tofacitinib twice daily at 3 months (65 patients). Data from the patients who received placebo during the first 3 months of the trial were pooled. The primary end points were the percentage of patients who had at least 20% improvement according to the criteria of the American College of Rheumatology (ACR20 response) and the change from baseline score on the Health Assessment Questionnaire-Disability Index (HAQ-DI; scores range from 0 to 3, with higher scores indicating greater disability) at the month 3 analysis. RESULTS At 3 months, the rates of ACR20 response were 50% with the 5-mg dose of tofacitinib and 47% with the 10-mg dose, as compared with 24% with placebo (P<0.001 for both comparisons); the corresponding mean changes from baseline in HAQ-DI score were -0.39 and -0.35, as compared with -0.14 (P<0.001 for both comparisons). Serious adverse events occurred in 4% of the patients who received the 5-mg dose of tofacitinib continuously and in 6% who received the 10-mg dose continuously. Over the course of 6 months, there were four serious infections, three herpes zoster infections, one myocardial infarction, and one ischemic stroke among the patients who received tofacitinib continuously. Elevations of aspartate and alanine aminotransferase concentrations of three or more times the upper limit of the normal range occurred in more patients who received tofacitinib continuously than in patients who received placebo followed by tofacitinib. CONCLUSIONS In this trial involving patients with active psoriatic arthritis who had had an inadequate response to TNF inhibitors, tofacitinib was more effective than placebo over 3 months in reducing disease activity. Adverse events were more frequent with tofacitinib than with placebo. (Funded by Pfizer; OPAL Beyond ClinicalTrials.gov number, NCT01882439 .).

Effect of pegylated phosphatidylserine-containing liposomes in experimental chronic arthritis. BMC Pharmacol Toxicol 2015; 16:24. [PMID: 26392267 PMCID: PMC4578330 DOI: 10.1186/s40360-015-0022-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2015] [Accepted: 08/21/2015] [Indexed: 11/29/2022] Open
Abstract
Background Phosphatidylserine-containing liposomes (PSL) have been shown to reduce inflammation in experimental models of acute arthritis, by mimicking the apoptotic process. The aim of this study was to evaluate the effect of pegylated PSL (PEG-PSL) on chronic inflammation of collagen induced arthritis (CIA) in DBA/1J mice. Methods CIA was induced in 24 DBA/1J mice (n = 6/group), which were divided into control (0.9 % saline) or treated with PEG-PSL (5, 10 and 15 mg/kg/day, subcutaneously for 20 days). Clinical score, limb histology and measurement of cytokines in knee joints of animals by ELISA and cytometric bead array (CBA) were evaluated. The in vitro study employed macrophage cultures stimulated with 100 ng/ml of LPS plus 10 ng/ml of PMA and treated with 100 μM PEG-PSL. Results Resolution of the disease in vivo and the inflammatory process in vitro were not observed. PEG-PSL, in doses of 10 and 15 mg/kg, were not shown to reduce the score of the disease in animals, whereas with the dose of 5 mg/kg, the animals did not show the advanced stage of the disease when compared to the controls. The PEG- PSL 5, 10 and 15 mg/kg treatment groups did not show significant reduction of TNF-α, IL-1β, IL-6, IL-2 and IFN-γ when compared to the controls. Disease incidence and animal weights were not affected by treatment. Regarding the paw histology, PEG-PSL did not yield any reductions in the infiltrating mononuclear, synovial hyperplasia, extension of pannus formation, synovial fibrosis, erosion of cartilage, bone erosion or cartilage degradation. The concentration of 100 μM of PEG-PSL has not been shown to reduce inflammation induced by LPS/PMA in the in vitro study. Treated groups did not show any reduction in inflammatory cytokines in the knee joints of animals affected by the disease compared to the control, although there were higher concentrations of TGF-β1 in all experimental groups. Conclusion The experimental model showed an expression of severe arthritis after the booster. TGF-β1 as well other pro inflammatory cytokines were presented in high concentrations in all groups. PEG-PSL had no impact on the clinical score, the histopathology from tibial-tarsal joints or the production of cytokines in the knee joints. Other alternatives such as dosage, route of administration, and as an adjunct to a drug already on the market, should be evaluated to support the use of PEG-PSL as a new therapeutic tool in inflammatory diseases.

[Epidemiologic profile of juvenile-onset compared to adult-onset spondyloarthritis in a large Brazilian cohort]. REVISTA BRASILEIRA DE REUMATOLOGIA 2014; 54:424-30. [PMID: 25458023 DOI: 10.1016/j.rbr.2014.06.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2013] [Revised: 05/07/2014] [Accepted: 06/02/2014] [Indexed: 01/30/2023] Open
Abstract
OBJECTIVE To analyze the clinical and epidemiologic characteristics of juvenile-onset spondyloarthritis (SpA) (< 16 years) and compare them with a group of adult-onset (≥ 16 years) SpA patients. PATIENTS AND METHODS Prospective, observational and multicentric cohort with 1,424 patients with the diagnosis of SpA according to the European Spondyloarthropathy Study Group (ESSG) submitted to a common protocol of investigation and recruited in 29 reference centers participants of the Brazilian Registry of Spondyloarthritis (RBE - Registro Brasileiro de Espondiloartrites). Patients were divided in two groups: age at onset<16 years (JOSpA group) and age at onset ≥ 16 years (AOSpA group). RESULTS Among the 1,424 patients, 235 presented disease onset before 16 years (16.5%). The clinical and epidemiologic variables associated with JOSpA were male gender (p<0.001), lower limb arthritis (p=0.001), enthesitis (p=0.008), anterior uveitis (p=0.041) and positive HLA-B27 (p=0.017), associated with lower scores of disease activity (Bath Ankylosing Spondylitis Disease Activity Index - BASDAI; p=0.007) and functionality (Bath Ankylosing Spondylitis Functional Index - BASFI; p=0.036). Cutaneous psoriasis (p<0.001), inflammatory bowel disease (p=0.023), dactylitis (p=0.024) and nail involvement (p=0.004) were more frequent in patients with adult-onset SpA. CONCLUSIONS Patients with JOSpA in this large Brazilian cohort were characterized predominantly by male gender, peripheral involvement (arthritis and enthesitis), positive HLA-B27 and lower disease scores.

Abstract
Etanercept was the first tumour necrosis factor alpha antagonist approved in the USA for the treatment of rheumatoid arthritis, in 1998, and then for other diseases. With the etanercept patent set to expire in the EU in 2015, a number of etanercept copies have reached the production phase and are undergoing clinical trials, with the promise of being cheaper alternatives to the reference product. In a global scenario that is favourable to the entry of biosimilars, this article discusses the stage of development, manufacture, clinical trials and the regulatory process involved in the approval of etanercept biosimilars, compiling the literature data. Reducing treatment cost is the principal attraction for biosimilars to emerge in the global market. It is essential for the doctors’ decision on the prescription of these medications, as well as for payers, to have clearly defined studies of clinical equivalence, quality, and safety in order to better evaluate the various copies of etanercept. The authors discuss the need to harmonize different national regulations and the introduction of effective pharmacosurveillance systems for prompt recognition of adverse effects in copies of biopharmaceuticals that differ from those found in the reference products.

Abstract
OBJECTIVES This study analysed the frequency of anterior uveitis (AU) and its correlations in a large cohort of patients with spondyloarthritis (SpA). METHODS A common protocol of investigation was prospectively applied to 2012 SpA patients in 85 centres from 10 Ibero-American countries. Clinical and demographic variables and disease indexes were investigated. Categorical variables were compared by χ2 and Fisher's exact test, and continuous variables were compared by ANOVA or Kruskal-Wallis test. A value of p<0.05 was considered significant. RESULTS AU was referred by 372 SpA patients (18.5%). AU was statistically associated with inflammatory low back pain (p<0.001), radiographic sacroiliitis (p<0.001), enthesopathies (p=0.004), urethritis/acute diarrhoea (p<0.001), balanitis (p=0.002), hip involvement (p=0.002), HLA-B27 (p=0.003), and higher C-reactive protein (p=0.001), whilst it was negatively associated with the number of painful (p=0.03) and swollen (p=0.005) peripheral joints, psoriatic arthritis (p<0.001), psoriasis (p<0.001), nail involvement (p<0.001), and dactilitis (p=0.062; trend). No association with gender, race, and indices (disease activity, functionality and quality of life) was observed. Logistic regression showed that ankylosing spondylitis (p=0.001) and HLA-B27 (p=0.083; trend) was significantly associated with AU, while extra-articular manifestations (predominantly psoriasis) were negatively associated (p=0.016). CONCLUSIONS Anterior uveitis is a frequent extra-articular manifestation in SpA patients, positively associated with axial involvement and HLA-B27 and negatively associated with peripheral involvement and psoriatic arthritis.

Abstract
OBJECTIVES To analyse demographic and clinical variables in patients with disease onset before and after 40, 45 and 50 years in a large series of Brazilian SpA patients. METHODS A common protocol of investigation was prospectively applied to 1424 SpA patients in 29 centres distributed through the main geographical regions in Brazil. The mean age at disease onset was 28.56 ± 12.34 years, with 259 patients (18.2%) referring disease onset after 40 years, 151 (10.6%) after 45 years and 81 (5.8%) after 50 years. Clinical and demographic variables and disease indices (BASDAI, BASFI, BASRI, MASES, ASQoL) were investigated. Ankylosing spondylitis was the most frequent disease (66.3%), followed by psoriatic arthritis (18%), undifferentiated SpA (6.7%), reactive arthritis (5.5%), and enteropathic arthritis (3.5%). RESULTS Comparing the groups according to age of disease onset, those patients with later onset presented statistical association with female gender, peripheral arthritis, dactylitis, nail involvement and psoriasis, as well as negative statistical association with inflammatory low back pain, alternating buttock pain, radiographic sacroiliitis, hip involvement, positive familial history, HLA-B27 and uveitis. BASDAI, BASFI and quality of life, as well as physicians and patient's global assessment, were similar in all the groups. Radiographic indices showed worse results in the younger age groups. CONCLUSIONS There are two different clinical patterns in SpA defined by age at disease onset: one with predominance of axial symptoms in the group with disease onset ≤ 40 years and another favouring the peripheral manifestations in those with later disease onset.

Abstract
SAPHO syndrome is an uncommon clinical entity, recently described in literature, which usually affects children, young adults and middle-aged people. It is defined by the association of skin lesions (severe acne, palmo-plantar pustulosis, supurative hidradenitis), synovitis, hiperosthosis and osteitis; however, not all manifestations are required for correct diagnosis. We report a currently forty-two year-old man who initiated follow-up in 1992 for severe acne. His diagnosis changed along the years and has been treated with antibiotics many times to control pustule formation and hidrosadenitis, which evolved to keloidal scars, requiring neck zethaplasty due to limitation of mobility. In 1996 isotretinoin was started, with good response to treatment but recurrence after its completion. Ten years later, isotretinoin was being used again due to worsening clinical picture when the patient developed polyarthritis, lost 11kg in 3 months and was found to have an elevated erythrocyte sedimentation rate. SAPHO syndrome was then diagnosed by the Rheumatology clinic, which started methotrexate at 10mg per week to a good clinical response. Several cutaneous and articular flares have occurred since, however he is now clinically stable with methotrexate 20mg per week and finasteride 5mg per day. SAPHO syndrome is a rare disease and its diagnosis is often late and difficult. In this case, skin lesions preceded arthritis in several years and have been resistant to other common treatments. The patient had a better improve after initiation of methotrexate. Although the skin disease has evolved to keloids, the patient has had excellent treatment response.

Abstract
There are several artists that have suffered rheumatic diseases. Even then, they continued their creative activity. Paul Klee suffered from systemic sclerosis, Dufy and Renoir suffered from rheumatoid arthritis and Gaudí and Boticelli had systemic-onset juvenile idiopathic arthritis. The famous noucentism sculptor, Manolo Hugué, presented chronic polyarthritis that suggested rheumatoid arthritis. Although he underwent several treatments, such as hydrotherapy or diathermic therapy, he had to stop sculpting. Using the chisel was too painful for his hands. He began, then, painting and composing poetry.

Abstract
Stiff skin syndrome is a rare cutaneous disease, scleroderma-like disorder that presents in infancy or early childhood with rock-hard skin, limited joint mobility, and mild hypertrichosis. Normally, it occurs in the absence of visceral or muscle involvement. Patients do not present immunologic abnormalities or vascular hyperactivity. We describe two adults who initially were diagnosed suffering from scleroderma but fit criteria for stiff skin syndrome. A review of the clinical range of this disorder and discussion of the differential diagnosis with scleroderma is presented.
