Cause-specific mortality in patients with psoriatic arthritis and rheumatoid arthritis.

ABSTRACT:

Objective

The objective of this study was to examine cause-specific mortality in patients with PsA compared with the general population and compared with patients with RA.

Methods

A cohort study was performed using The Health Improvement Network among patients aged 18-89 years with data from 1994 to 2010. PsA and RA were defined by medical codes, and up to 10 unexposed controls were matched on practice and start date within the practice. Cause of death was classified using categories from UK death statistics. Each death was manually reviewed to ensure appropriate classification. Age- and sex-adjusted hazard ratios (HRs) and multivariable adjusted HRs were calculated using competing risks survival regression.

Results

Among patients with PsA (8706), RA (41 752) and unexposed controls (81 573), 470, 7004 and 5269 deaths were observed, respectively. The most common causes of death among all patients were cardiovascular disease, followed by malignancy, respiratory deaths and infection. Cause of death was unknown in ?25%. Among PsA patients, cardiovascular (1.09, 0.91-1.32), respiratory (0.97, 0.79-1.20), malignancy (1.03, 0.86-1.25) and infection deaths (1.05, 0.79-1.39) were not elevated. Among patients with RA, cardiovascular (1.55, 1.44-1.66), respiratory (1.85, 1.72-2.01), malignancy (1.18, 1.08-1.28) and infection deaths (2.21, 2.00-2.44) were significantly elevated compared with population controls. Although less common, suicide deaths were elevated in PsA and RA (HR 3.03 and 2.47, respectively).

Conclusion

Overall mortality and cause-specific mortality risk were not elevated among patients with PsA except for suicide deaths. Patients with RA were at increased risk of deaths from cardiovascular, respiratory, cancer and infectious diseases.

Project description:IntroductionRisk of herpes zoster (HZ) is increased with Janus kinase inhibitor use. We evaluated clinical study data relating to HZ management in patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) receiving tofacitinib.MethodsThis post hoc analysis included data from 21 RA and 3 PsA clinical studies; data were pooled for tofacitinib doses. Outcomes of HZ events (serious and non-serious) and tofacitinib treatment changes were evaluated in response to first and second HZ events. Median time to resolution was stratified by dermatomal involvement, history of HZ prior to tofacitinib, changes to tofacitinib treatment, anti-viral and corticosteroid use, and tofacitinib dose.ResultsSeven hundred eighty-three (11.1%, N = 7061) patients with RA experienced ≥ 1 HZ event, 63 (8.0%) of whom had ≥ 2 HZ events. In patients with PsA, 36 (4.6%, N = 783) experienced ≥ 1 HZ event, 1 (2.8%) of whom had ≥ 2 HZ events. For most HZ events, tofacitinib treatment was unchanged or temporarily discontinued. The majority of patients received anti-viral treatment, most within 3 days of onset. Post-herpetic neuralgia developed in 6.9% and 3.2% of patients with RA with first and second events, respectively, and in 2.8% of patients with PsA with a first event. Most first and second events resolved (RA: 97.6% and 96.8%, respectively; PsA: 94.4% and 100%, respectively). Median time to resolution was 22.0 days for first and 15.0 days for second events for RA and 20.5 days for first and 11.0 days for second events (n = 1) for PsA. Time to resolution of first events for RA and PsA was generally numerically shorter for patients with single dermatomal HZ, history of HZ, or anti-viral use versus those without.ConclusionAmong patients receiving tofacitinib, recurrent events were more common in patients with RA versus PsA; HZ duration was shorter for repeat events.Trial registrationNCT01262118, NCT01484561, NCT00147498, NCT00413660, NCT00550446, NCT00603512, NCT00687193, NCT01164579, NCT00976599, NCT01059864, NCT01359150, NCT02147587, NCT00960440, NCT00847613, NCT00814307, NCT00856544, NCT00853385, NCT01039688, NCT02187055, NCT00413699, NCT00661661, NCT01877668, NCT01882439, NCT01976364.

Project description:Background and aimsGM-CSF-dependent macrophage polarization has been demonstrated in rheumatoid arthritis (RA). Our aim was to seek diagnostic/prognostic biomarkers for undifferentiated arthritis (UA) by analyzing GM-CSF expression and source, macrophage polarization and density in joints of patients with UA evolving to RA or PsA compared with established RA or PsA, respectively.MethodsSynovial tissue (ST) from patients with UA evolving to RA (UA>RA, n=8), PsA (UA>PsA, n=9), persistent UA (UA, n=16), established RA (n=12) and PsA (n=10), and healthy controls (n=6), were analyzed. Cell source and quantitative expression of GM-CSF and proteins associated with pro-inflammatory (GM-CSF-driven) and anti-inflammatory (M-CSF-driven) macrophage polarization (activin A, TNFα, MMP12, and CD209, respectively) were assessed in ST CD163+ macrophages by multicolor immunofluorescence. GM-CSF and activin A levels were also quantified in paired synovial fluid samples. CD163+ macrophage density was determined in all groups by immunofluorescence.ResultsSynovial stromal cells (FAP+ CD90+ fibroblast, CD90+ endothelial cells) and CD163+ sublining macrophages were the sources of GM-CSF. ST CD163+ macrophages from all groups expressed pro-inflammatory polarization markers (activin A, TNFα, and MMP12). Expression of the M-CSF-dependent anti-inflammatory marker CD209 identified two macrophage subsets (CD163+ CD209high and CD163+ CD209low/-). CD209+ macrophages were more abundant in ST from healthy controls and PsA patients, although both macrophage subtypes showed similar levels of pro-inflammatory markers in all groups. In paired synovial fluid samples, activin A was detected in all patients, with higher levels in UA>RA and RA, while GM-CSF was infrequently detected. ST CD163+ macrophage density was comparable between UA>RA and UA>PsA patients, but significantly higher than in persistent UA.ConclusionsGM-CSF is highly expressed by sublining CD90+ FAP+ synovial fibroblasts, CD90+ activated endothelium and CD163+ macrophages in different types of arthritis. The polarization state of ST macrophages was similar in all UA and established arthritis groups, with a predominance of pro-inflammatory GM-CSF-associated markers. CD163+ macrophage density was significantly higher in the UA phases of RA and PsA compared with persistent UA. Taken together, our findings support the idea that GM-CSF is a strong driver of macrophage polarization and a potential therapeutic target not only in RA but also in PsA and all types of UA.

Project description:BackgroundDifferential diagnosis among psoriatic arthritis (PsA) and seronegative rheumatoid arthritis (Abneg RA) can be challenging particularly in the clinical setting of peripheral phenotype and autoantibodies seronegativity. The aim of the study was to identify synovial tissue (ST) biomarkers differentially expressed in PsA and Abneg RA and test their predictive value of therapeutic response.MethodsThirty-four PsA patients [12 DMARD naive and 22 non-responder to methotrexate (MTX-IR)] with peripheral joint involvement and 55 Abneg RA (27 DMARD naive and 28 MTX-IR) underwent US-guided ST biopsy and immunohistochemistry (IHC) for CD68+, CD3+, CD20+, CD21+, CD117+, and CD138+ cells. After study entry, each DMARD-naive patient started MTX therapy and was followed in an outpatient setting for at least 6 months to define the achievement of Minimal Disease Activity (PsA) and DAS remission (Abneg RA) status respectively. Each IR-MTX patient was treated according to EULAR recommendations.ResultsAt study entry, IHC analysis revealed that PsA patients had comparable levels of lining and sublining CD68+ and sublining CD21+, CD20+, and CD3+ cells than Abneg RA, despite the therapeutic regimen. Moreover, regardless of the therapeutic scheme, PsA patients showed higher IHC score of CD117+ cells (p = 0.0004 and p = 0.0005 for naive and MTX-IR patients respectively) compared to Abneg RA patients. Conversely, Abneg RA patients showed higher IHC score of CD138+ cells, irrespective to the therapeutic scheme (p = 0.04 and p = 0.002 for naive and MTX-IR patients respectively). Analyzing the response rate to the therapeutic scheme, naive PsA patients reaching MDA status at 6 months follow-up, showed, at the study entry, lower IHC score of CD3+ cells compared to PsA patients not reaching this outcome (p = 0.02); conversely, naive Abneg RA patients reaching DAS remission status at 6 months follow-up, showed, at the study entry, lower IHC score of sublining CD68+ cells compared to Abneg RA patients not reaching this outcome (p < 0.001).ConclusionsCD117+ and CD138+ cells are differentially distributed among PsA and Abneg RA. Histological analysis of ST may help to solve the clinical overlap between the two diseases and provides prognostic data about the therapy success.

Project description:IntroductionThe safety of tofacitinib in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) has been demonstrated in clinical studies of ≤ 4 and 9.5 years, respectively. Post-marketing surveillance (PMS) data for tofacitinib from spontaneous and voluntary adverse event (AE) reports have been published for RA, but not PsA. To inform the real-world safety profile of tofacitinib in PsA, we evaluated AE reports submitted to the Pfizer safety database (including RA data for context).MethodsEndpoints included AEs, serious AEs (SAEs), AEs of special interest (AESIs; serious infections, herpes zoster, cardiovascular events, malignancies, venous thromboembolism), and fatal cases. Exposure was estimated using IQVIA global commercial sales data. Number, frequency, and reporting rates (RRs; number of events/100 patient-years' [PY] exposure) were summarized by indication and formulation (immediate release [IR] 5 or 10 mg twice daily], modified release [MR] 11 mg once daily, or all tofacitinib). The data-collection period differed by indication (PsA: 14 December 2017 [US approval, IR/MR] to 6 November 2021; RA: 6 November 2012 [US approval, IR] to 6 November 2021; MR approval, 24 February 2016).ResultsA total of 73,525 case reports were reviewed (PsA = 5394/RA = 68,131), with 20,706/439,370 PY (PsA/RA) of exposure. More AEs were reported for IR versus MR (IR/MR: PsA = 8349/7602; RA = 137,476/82,153). RRs for AEs (IR/MR: PsA = 59.6/113.4; RA = 44.0/64.8) and SAEs (PsA = 8.1/13.6; RA = 8.0/9.5) were higher with MR versus IR. AE RRs (RA) in the first 4 years after IR approval were 95.9 (IR; 49,439 PY) and 147.0 (MR; 2000 PY). Frequency of SAEs, AESIs, and fatal cases was mostly similar across formulations and indications. The most frequently-reported AE Preferred Terms (PsA/RA) included drug ineffective (20.0%/17.8%), pain (9.7%/10.6%), condition aggravated (9.9%/10.5%), headache (8.8%/7.9%) and, for PsA, off-label use (10.5%/3.4%).ConclusionsTofacitinib PMS safety data from submitted AE reports were consistent between PsA and RA, and aligned with its known safety profile. Exposure data (lower MR versus IR; estimation from commercial sales data), reporting bias, reporter identity, and regional differences in formulation use limit interpretation.
