Analysis of Risk Factors for Developing Tuberculosis in Patients Who Received Prophylactic Latent Tuberculosis Infection Treatment with Experience of Biologic Medications.

Biologic medications have dramatically improved the treatment outcomes of immunological inflammatory diseases, but their immunosuppressive effects put patients at risk for tuberculosis (TB). We investigated the risk factors for developing TB in patients treated for latent tuberculosis infection (LTBI) who also had experience of using biologic medications. At Keio University Hospital, we retrospectively investigated patients treated with anti-mycobacterial drugs before or concurrently with biologic medications from January 2012 to August 2020. Patients in the 'follow-on cases group' who had a positive TB screening test after initiating biologic medications and subsequently started LTBI treatment were excluded. We researched and compared the patient characteristics for TB and non-TB patient groups. Of the 146 eligible patients, 5 (3.4%) developed TB. The incidence rate was 600/100000 person-years. There were no significant differences between TB and non-TB patient groups in the history of TB, interferon-gamma release assay (IGRA), duration of biologic medication therapy, LTBI treatment periods, concomitant use of calcineurin inhibitors or anti-rheumatic drugs. The percentage of patients who received prednisolone at a dose of ≥15 mg for more than 1 month was higher in those who developed TB than in those who did not (40.0 vs. 7.1%, p = 0.054); however, this difference was not statistically significant. Regular monitoring of TB is necessary for long-term concomitant use of high prednisolone doses during and after the administration of biologic medications.

OP119 Collectively Improving The Quality Use Of Highly Specialized Medicines: Starting With Biologics

IntroductionIn contrast to high-volume medicines prescribed by general practitioners, low-volume highly specialized medicines have not been supported by national quality use of medicine (QUM) programs in Australia. The first area addressed has focused on optimizing use of biological disease-modifying antirheumatic drugs (bDMARDs).MethodsThe program was designed, developed and implemented in partnership with nine consortium member organizations and four affiliate organizations representing consumer and clinical audiences, program development expertize and implementation capability. The common agenda for the collective impact approach was to achieve better health outcomes for people with inflammatory arthritis, inflammatory bowel disease and plaque psoriasis. Multidisciplinary expert working groups reviewed formative QUM research and agreed on objectives, audiences, messages and interventions. Interventions were selected based on identified barriers, enablers and behavioral drivers, informed by the Theoretical Domains Framework. Interventions were co-designed and tested with end-users. Marketing and promotion activity supported implementation of all interventions through consortium channels and networks. Evaluation includes process, impact and outcome measures, and a realist evaluation of the academic detailing.ResultsProgram objectives were to optimize: (i) first-line therapy before bDMARD use; (ii) first-choice bDMARDs; (iii) biosimilar prescribing and dispensing; (iv) bDMARD dosage; (v) glucocorticoid and analgesic use. Over 60 interventions supporting key messages for each objective were developed for audiences: consumers; rheumatologists, gastroenterologists, dermatologists; pharmacists; drug and therapeutic committees. Interventions implemented between September 2020 and September 2022 included: consumer decision aids, action plans, fact sheets, lived experience videos; living guidelines and evidence summaries; guidance/position statements for hospitals, podcasts, webinars, online learning; prescribing feedback reports; and academic detailing. Uptake of interventions has largely met targets and surveys have demonstrated shifts in specialist and consumer knowledge and behavior in line with key messages and objectives. Realist and outcome evaluation is ongoing.ConclusionsOur experience demonstrates the value of a consortium of stakeholder organizations, with different expertise and interests but agreed goals and roles, working together to progress the quality use of highly specialized drugs.

Cachexia Prevalence in a Population of Moroccan Women with Rheumatoid Arthritis.

To assess body composition in women with rheumatoid arthritis (RA) compared to healthy controls, to calculate the prevalence of rheumatoid Cachexia (RC), and to identify the associated factors. We conducted a case-control study on 112 female patients with RA according to the 2010 American College of Rheumatology/European League Against Rheumatism classification criteria for RA; and 224 age-matched healthy women. Body composition (BC) and bone mineral density (BMD) scans were obtained using Dual-energy X-ray absorptiometry (DXA). RC was defined by a fat-free mass index (FFMI) below the 10th percentile and a fat mass index (FMI) above the 25th percentile compared with the control group. We conducted a comparison between RA patients and healthy controls then a multiple regression analysis was conducted where the dependant variable is the presence of RC. RC prevalence was 42.85% while the mean body mass index (BMI) was the same in both groups. RA patients had a higher FM and lower FFM comparing to healthy controls. In our population, 78.60% of patients were on methotrexate and 12.50% on anti TNF therapy. Comparison between patients with and without RC showed that patients with RC have a higher proportion of erosive arthritis and of active disease. Regression logistic analysis showed that RC was significantly associated to erosive arthritis and active disease (OR at 33.31 (8.42-131.70) and 8.98 (1.64-49.20) respectively), independently of age, erythrocyte sedimentation rate, C-reactive protein, disease duration, steroid cumulative dose and biologic Disease-Modifying Anti-Rheumatic Drugs(bDMARDs) use. Our study showed that almost half of our RA patients have RC, even with a high BMI.

Is Serum Uric Acid Level Associated with Disease Activity in Rheumatoid Arthritis Patients.

An association between serum uric acid (UA) and disease activity in rheumatoid arthritis (RA) patients has not been well studied. We describe RA patients with high and normal UA and study its association with RA activity. Adult RA patients from the Kuwait Registry for Rheumatic Diseases (KRRD) were studied from February 2012 through March 2022. Patients with documented UA levels were included. UA of >357 µmol/L (6mg/dL) was considered high. Statistical comparison and correlation were made using multivariate logistic regression. Overall, 1054 patients with documented UA. A total of 158 patients (15%) had high UA level with a mean of 409± 44.4µmol/L. The mean age for the high UA group and low UA group were 59.3 ± 10.7 years and 54.5 ± 12.4 years, respectively (p<0.001). 49.4% were female in high UA group, and 62.2% were female in low UA group, respectively (p<0.05). Logistic analysis showed an inverse relation between DAS28 and UA, as lower DAS28 score was associated with higher UA level (p=0.032) OR 1.39. There was a direct relation with HAQ, creatinine and UA. A higher HAQ is associated with a higher UA level (p=0.019) OR 0.78. High creatinine level is also associated with high UA level (p<0.001) OR 0.24. The use of antirheumatic drugs was similar among patients with high and normal UA. RA patients with a higher UA had a lower disease activity despite using similar antirheumatic drugs. The reasons behind this association need to be further studied.

Symposium 8

Psoriatic arthritis (PsA) is a chronic inflammatory autoimmune condition characterized by inflamed joints. PsA often, but not always, occurs along with psoriasis (PsO), an autoimmune skin condition that results in scaly, red itchy patches. Biologics therapy has been a standard of treatment for moderate to severe PsA after the use of disease-modifying antirheumatic drugs (DMARDs). Traditionally PsA biologics targeted on inhibiting the tumor necrosis factor (TNF) or interleukin-17 (IL-17) pathway to suppress the inflammatory triggering cascade. Recently biologics inhibiting the interleukin-23 (IL-23) pathway, such as guselkumab, is approved for the management of both PsA and PsO with promising efficacy in both skin and joint improvement. IL-23 inhibitors are included as recommended treatment option for peripheral and skin-involved PsA in the latest EULAR recommendations. With the availability of new mode of therapy, it is important to understand the characteristics and clinical evidence of different biologics modality and this lecture will demonstrate how to apply the various options to PsA patients presented with different disease profiles.

Efficacy, retention rate and safety of adalimumab treatment in patients with non-infectious uveitis and scleritis: a real-world, retrospective, single-centre study.

To evaluate the outcomes of adalimumab (ADA) treatment of patients with non-infectious uveitis and scleritis, focusing on efficacy, retention rate, and safety. This retrospective, clinical cohort study included 62 patients (104 eyes) with active ocular inflammation treated with ADA. Primary outcomes were efficacy and cumulative drug retention rate (DRR) of ADA. The secondary outcomes included changes in ocular inflammatory parameters, changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT), corticosteroid-sparing effect, impact of concomitant use of disease-modifying antirheumatic drug (DMARD) and ADA as first or ≥2nd biotherapy line on DRR, and adverse events. Forty-five patients (72.6%) achieved inactive disease at the end of follow-up. DRR at 6, 12, 24, and 48 months was 96.8%, 89.2%, 63.1%, and 63.1%, respectively. Of the 18 patients whose bi-weekly ADA treatment was escalated to weekly ADA due to primary or secondary inefficacy, 10 patients had inactive disease finally. BCVA improved (p < 0.001) and CMT decreased (p < 0.001) significantly at 6, 12, and 24 months after ADA therapy compared to baseline. Percentage of patients treated with ≥10 mg/day corticosteroid (61.3% vs. 6.4%) and DMARDs combined with ADA (46.8% vs. 37.1%) were lower at 6 months than at baseline. Concomitant DMARDs (p = 0.579) and use of ADA as first or ≥2nd biotherapy line (p = 0.527) had no significant effect on DRR. Most common adverse event was tuberculosis-related infections. ADA seems to be effective and safe with good DRR to control ocular inflammation. Escalation to weekly ADA treatment may be an effective option in patients with primary or secondary inefficacy.

Initiation of Disease-Modifying Antirheumatic Drugs in Older Medicare Beneficiaries With New Diagnosis of Late-Onset Rheumatoid Arthritis.

Older adults with rheumatoid arthritis (RA) account for up to one-third of the RA population and are less likely to receive optimal treatment. For the subgroup of older adults with late-onset RA (LORA), who experience more symptomatic and progressive disease, suboptimal treatment could be more consequential than the general population who age with RA. We evaluated use of disease-modifying antirheumatic drugs (DMARDs) in older adults with a new diagnosis of LORA. In this retrospective observational study, we identified adults 66 years of age or older with a new diagnosis of LORA using Medicare data from 2008 to 2017. Information on baseline patient characteristics and DMARD initiation during the first 12 months after LORA diagnosis were collected. We also assessed concomitant use of glucocorticoids (GCs). We identified 33,373 older adults with new diagnosis of LORA. Average age at LORA diagnosis was 76.7 (SD 7.6); 75.4% were female, 76.9% were White, and 35.6% had low-income subsidy (LIS). Less than one-third were initiated on a DMARD (28.9%). In multivariable analyses, DMARD initiation was associated with younger age, fewer comorbidities, and absence of LIS status. Concomitant long-term (>3 months) GC use was higher among those on any DMARD (44.3%) compared with those without (15.2%). DMARD initiation after new diagnosis of LORA is low despite current clinical practice guidelines recommending early aggressive initiation of treatment. Long-term GC use is common among those on any DMARDs, raising concern for suboptimal DMARD use. Further studies are needed to understand drivers of DMARD use in older adults.

Comparison of Hand-Wrist Findings of Rheumatoid Arthritis Patients According to the Use of Synthetic and Biological Disease-Modifying Antirheumatic Drugs (DMARDs): A Clinical, Radiographic, and Ultrasonographic Study.

The aim of this study is to evaluate the hand-wrist findings in patients with rheumatoid arthritis (RA) using synthetic and a combination of synthetic and biological disease-modifying antirheumatic drugs (DMARDs) in terms of ultrasonographic, clinical, and radiographic data. The study is designed as a cross-sectional study, and 31 RA patients followed up in the rheumatology outpatient clinic were enrolled. Nineteen patients were using only synthetic DMARDs, and 12 patients were using a combination of synthetic and biological DMARDs. The clinical data of each patient were recorded simultaneously. Disease Activity Score-28 (DAS-28) was used for the assessment of disease activation, and the Health Assessment Questionnaire (HAQ) score was used for the evaluation of general health status. Bilateral proximal interphalangeal (PIP), metacarpophalangeal (MCP) joints, and the radiocarpal, ulnocarpal, and midcarpal joints of the patients were examined by ultrasonography (US). The Sharp-van der Heijde modified score was used to determine the radiographic damage. There was no significant difference between the two groups in terms of demographic data, clinical findings, ESR, and CRP. When the groups were compared in terms of right and left PIP, MCP, and radiocarpal, ulnocarpal, and midcarpal synovitis grade total scores, no significant difference was found between the two groups. Radiographic total joint space scores were significantly lower in the group receiving only synthetic DMARD treatment (p=0.047) and 25-OH vitamin D levels were significantly higher (p=0.008). This study revealed that there was no significant difference between groups except radiographic total joint space scores.

Performance of artificial intelligence chatbot as a source of patient information on anti-rheumatic drug use in pregnancy

Background/Aim: Women with rheumatic and musculoskeletal disorders often discontinue using their medications prior to conception or during the few early weeks of pregnancy because drug use during pregnancy frequently results in anxiety. Pregnant women have reported seeking out health-related information from a variety of sources, particularly the Internet, in an attempt to ease their concerns about the use of such medications during pregnancy. The objective of this study was to evaluate the accuracy and completeness of health-related information concerning the use of anti-rheumatic medications during pregnancy as provided by Open Artificial Intelligence (AI's) Chat Generative Pre-trained Transformer (ChatGPT) versions 3.5 and 4, which are widely known AI tools. Methods: In this prospective cross-sectional study, the performances of OpenAI's ChatGPT versions 3.5 and 4 were assessed regarding health information concerning anti-rheumatic drugs during pregnancy using the 2016 European Union of Associations for Rheumatology (EULAR) guidelines as a reference. Fourteen queries from the guidelines were entered into both AI models. Responses were evaluated independently and rated by two evaluators using a predefined 6-point Likert-like scale (1 – completely incorrect to 6 – completely correct) and for completeness using a 3-point Likert-like scale (1 – incomplete to 3 – complete). Inter-rater reliability was evaluated using Cohen’s kappa statistic, and the differences in scores across ChatGPT versions were compared using the Mann–Whitney U test. Results: No statistically significant difference between the mean accuracy scores of GPT versions 3.5 and 4 (5 [1.17] versus 5.07 [1.26]; P=0.769), indicating the resulting scores were between nearly all accurate and correct for both models. Additionally, no statistically significant difference in the mean completeness scores of GPT 3.5 and GPT 4 (2.5 [0.51] vs 2.64 [0.49], P=0.541) was found, indicating scores between adequate and comprehensive for both models. Both models had similar total mean accuracy and completeness scores (3.75 [1.55] versus 3.86 [1.57]; P=0.717). In the GPT 3.5 model, hydroxychloroquine and Leflunomide received the highest full scores for both accuracy and completeness, while methotrexate, Sulfasalazine, Cyclophosphamide, Mycophenolate mofetil, and Tofacitinib received the highest total scores in the GPT 4 model. Nevertheless, for both models, one of the 14 drugs was scored as more incorrect than correct. Conclusions: When considering the safety and compatibility of anti-rheumatic medications during pregnancy, both ChatGPT versions 3.5 and 4 demonstrated satisfactory accuracy and completeness. On the other hand, the research revealed that the responses generated by ChatGPT also contained inaccurate information. Despite its good performance, ChatGPT should not be used as a standalone tool to make decisions about taking medications during pregnancy due to this AI tool’s limitations.

Tofacitinib Efficacy and Safety in Patients With Ankylosing Spondylitis by Prior Biologic Disease-Modifying Antirheumatic Drug Use: A Post Hoc Analysis.

To evaluate the efficacy and safety of tofacitinib in patients with ankylosing spondylitis (AS) by prior biologic disease-modifying antirheumatic drug (bDMARD) use. Data from a placebo-controlled, double-blind study of patients with active AS were analyzed. Patients received tofacitinib 5 mg twice daily (BID) or placebo to week 16; all received open-label tofacitinib 5 mg BID to week 48 and were stratified by prior treatment (bDMARD-naive or tumor necrosis factor inhibitor [TNFi]-inadequate responder [IR], including bDMARD-experienced [non-IR]). Disease activity/safety were assessed throughout. Of 269 patients, 207 (77%) were bDMARD-naive; 62(23%) were in the TNFi-IR subgroup. TNFi-IR patients had higher baseline BMI (28.0 vs. 26.1 kg/m2 ), longer symptom duration (14.4 vs. 13.2 years), and lower concomitant conventional synthetic DMARD use (14.5% vs. 30.9%) than bDMARD-naive patients. At week 16, for most outcomes, tofacitinib efficacy exceeded placebo for both subgroups and was sustained to week 48. At week 16, tofacitinib versus placebo differences were similar between bDMARD-naive and TNFi-IR patients (Assessment in Spondyloarthritis international Society 40 treatment difference [95% confidence interval]: 30.8% [19.1%-42.6%] vs. 19.4% [1.7%-37.0%]). Adverse event (AE) proportions were similar between tofacitinib-treated bDMARD-naive/TNFi-IR patients (77.5%/77.4%) at week 48 with no deaths. A numerically higher proportion of tofacitinib-treated TNFi-IR versus bDMARD-naive patients discontinued study drug (12.9% vs. 3.9%) or dose reduced/temporarily discontinued due to AEs (19.4% vs. 11.8%). Tofacitinib efficacy exceeded placebo at week 16 for bDMARD-naive/TNFi-IR patients and was sustained to week 48. The absolute magnitude of responses was generally greater in bDMARD-naive patients versus TNFi-IR patients. More TNFi-IR versus bDMARD-naive patients discontinued or dose reduced/temporarily discontinued tofacitinib due to AEs. Small sample size and sample size differences between subgroups limited the interpretation.

Effect of Nintedanib in Patients with Progressive Pulmonary Fibrosis in Subgroups with Differing Baseline Characteristics.

In the INBUILD trial in patients with progressive pulmonary fibrosis other than idiopathic pulmonary fibrosis (IPF), nintedanib slowed the rate of decline in forced vital capacity (FVC; mL/year) over 52weeks compared with placebo. We assessed the efficacy of nintedanib across subgroups in the INBUILD trial by baseline characteristics. We assessed the rate of decline in FVC over 52weeks and time to progression of interstitial lung disease (ILD) (absolute decline from baseline in FVC % predicted>10%) or death over the whole trial in subgroups based on sex, age, race, body mass index (BMI), time since diagnosis of ILD, FVC % predicted, diffusing capacity of the lungs for carbon monoxide (DLco) % predicted, composite physiologic index (CPI), GAP (gender, age, lung physiology) stage, use of anti-acid therapy and use of disease-modifying antirheumatic drugs (DMARDs) at baseline. The effect of nintedanib versus placebo on reducing the rate of decline in FVC over 52weeks was consistent across the subgroups by baseline characteristics analysed. Interaction p values did not indicate heterogeneity in the treatment effect between these subgroups (p>0.05). Over the whole trial (median follow-up time ∼19months), progression of ILD or death occurred in similar or lower proportions of patients treated with nintedanib than placebo across the subgroups analysed, with no heterogeneity detected between the subgroups. In the INBUILD trial, no heterogeneity was detected in the effect of nintedanib on reducing the rate of ILD progression across subgroups based on demographics, ILD severity or use of anti-acid therapy or DMARDs. These data support the use of nintedanib as a treatment for progressive pulmonary fibrosis. ClinicalTrials.gov Identifier: NCT02999178.

Effect of JAK inhibitors on the three forms of bone damage in autoimmune arthritis: joint erosion, periarticular osteopenia, and systemic bone loss

BackgroundThe types of bone damage in rheumatoid arthritis (RA) include joint erosion, periarticular osteoporosis, and systemic osteoporosis. Janus kinase (JAK) inhibitors ameliorate inflammation and joint erosion in RA, but their effect on the three types of bone loss have not been reportedly explored in depth. We aimed to clarify how JAK inhibitors influence the various types of bone loss in arthritis by modulating osteoclastic bone resorption and/or osteoblastic bone formation.MethodsCollagen-induced arthritis (CIA) mice were treated with a JAK inhibitor after the onset of arthritis. Micro-computed tomography (μCT) and histological analyses (bone morphometric analyses) on the erosive calcaneocuboid joint, periarticular bone (distal femur or proximal tibia), and vertebrae were performed. The effect of four different JAK inhibitors on osteoclastogenesis under various conditions was examined in vitro.ResultsThe JAK inhibitor ameliorated joint erosion, periarticular osteopenia and systemic bone loss. It reduced the osteoclast number in all the three types of bone damage. The JAK inhibitor enhanced osteoblastic bone formation in the calcaneus distal to inflammatory synovium in the calcaneocuboid joints, periarticular region of the tibia and vertebrae, but not the inflamed calcaneocuboid joint. All the JAK inhibitors suppressed osteoclastogenesis in vitro to a similar extent in the presence of osteoblastic cells. Most of the JAK inhibitors abrogated the suppressive effect of Th1 cells on osteoclastogenesis by inhibiting IFN-γ signaling in osteoclast precursor cells, while a JAK inhibitor did not affect this effect due to less ability to inhibit IFN-γ signaling.ConclusionsThe JAK inhibitor suppressed joint erosion mainly by inhibiting osteoclastogenesis, while it ameliorated periarticular osteopenia and systemic bone loss by both inhibiting osteoclastogenesis and promoting osteoblastogenesis. These results indicate that the effect of JAK inhibitors on osteoclastogenesis and osteoblastogenesis depends on the bone damage type and the affected bone area. In vitro studies suggest that while JAK inhibitors inhibit osteoclastic bone resorption, their effects on osteoclastogenesis in inflammatory environments vary depending on the cytokine milieu, JAK selectivity and cytokine signaling specificity. The findings reported here should contribute to the strategic use of antirheumatic drugs against structural damages in RA.

Systematic Literature Review of Real-World Evidence on Baricitinib for the Treatment of Rheumatoid Arthritis.

Baricitinib, an orally available small-molecule inhibitor of Janus kinase (JAK)1 and JAK2, is indicated to treat active moderate-to-severe rheumatoid arthritis (RA). This systematic review described the real-world clinical characteristics of baricitinib-treated patients with RA, prescription patterns, effectiveness, drug persistence, patient-reported outcomes (PROs; physical function, pain, health-related quality of life [HRQoL]), patient global assessment (PGA), and safety of baricitinib. A PRISMA systematic review of real-world studies was conducted to identify relevant literature published between January 2016 and September 2022 using MEDLINE®, EMBASE®, and evidence-based medicine review databases. Websites or online repositories of the American College of Rheumatology and the European Alliance of Associations for Rheumatology were searched manually to include relevant abstracts from conferences held between January 2016 and November 2022. A total of 11,472 records were identified by searching online databases. Seventy studies were included in the study, of which 40 were abstracts. Most patients were older (51-71 years), female, and with mean RA duration of 4-19 years. Baricitinib was mostly used after the failure of one or more bDMARDs, and 4 mg dosing was prevalent in patients with RA (range 22-100%). Clinical effectiveness of baricitinib was reported in real-world settings regardless of prior biologic/targeted synthetic disease-modifying antirheumatic drug (DMARD) use and concomitant conventional synthetic DMARD use. Achievement of Clinical Disease Activity Index (CDAI) remission was reported in 8.7-60% of patients at week 12 and CDAI low disease activity (LDA) in 20.2-81.6% at week 24. The proportion of patients attaining Simple Disease Activity Index (SDAI) remission was reported in 12% at week 4 to 45.4% at 24 weeks. Drug persistence was high, similar, or equal to anti-tumor necrosis factor drugs. No new safety signals were identified. Baricitinib demonstrated effectiveness in the real-world setting with a consistent safety profile observed in clinical studies. Better persistence rates for baricitinib compared to bDMARDs with improvement in PROs were reported, although baricitinib-treated patients had RA with poor prognostic characteristics.

Clinical characteristics of patients with rheumatic diseases and abnormal liver function

Objective: To investigate the clinical characteristics of patients with rheumatic diseases and abnormal liver function, as well as determine the proportion and severity of liver function abnormalities. Methods: Cross-sectional study. Data were collected from patients registered in the Chinese Rheumatism Date Center from 2011 to 2021. The rheumatic diseases analyzed in this study were rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren syndrome (SS), ankylosing spondylitis (AS), and gout. Patient data, including demographic characteristics [ such as age, sex, body mass index,(BMI), and smoking history], liver function test results [including alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase(ALP), and total bilirubin], and use of anti-rheumatic immune drugs and liver-protective drugs, were collected and compared between groups with normal and abnormal liver functions. In addition, the proportions of abnormal liver function were compared between sex and age groups. Results: A total of 116 308 patients were included in this study, including 49 659 with RA, 17 597 with SLE, 9 039 with SS, 11 321 with AS, and 28 692 with gout. The lowest proportion of liver function abnormalities was observed in patients with RA[11.02% (5 470/49 659)], followed by those with SS[17.97% (1 624/9 039)] and AS [18.22% (2 063/11 321) ], whereas patients with SLE [21.14% (3 720/17 597) ] and gout [28.73% (8 242/28 692)] exhibited the highest proportion of these abnormalities. Elevated ALT, mostly classified as grade 1, was the most commonly noted liver function abnormality, whereas elevated ALP was the least common. Some patients who took liver-protective drugs had normal liver function, with the lowest percentage observed in patients with gout [7.45% (36/483) ] and ranging from 21.7% to 30.34% in patients with RA, SLE, SS, and AS. The proportion of liver function abnormalities was higher in males than in females for all disease types [RA: 13.8%(1 368/9 906) vs. 10.3%(4 102/39 753); SLE: 33.6% (479/1 424) vs. 20.0% (3 241/16 173); SS: 25.4%(111/437) vs. 17.6%(1 513/8 602); AS: 20.1%(1 629/8 119) vs. 13.6% (434/3 202); and gout: 29.3% (8 033/27 394) vs. 16.1% (209/1 298)]. In RA, SLE, and AS, the proportions of liver function abnormalities were similar across all age groups. In SS, the proportion of liver function abnormalities increased with age [<40 years: 14.9%(294/1 979); 40-59 years: 18.1%(858/4 741); ≥60 years: 20.4%(472/2 319)], whereas a reversal of this trend was observed in gout [<40 years: 34.9%(4 294/12 320); 40-59 years: 25.5%(2 905/11 398);≥60 years: 21.0%(1 042/4 971)]. Conclusions: The proportions of combined liver function abnormalities in patients with rheumatologic diseases were high, and the utilization rates of liver-protective drugs were low. It is necessary to pay more attention to monitoring patients' liver function, timely administer liver-protective drugs, and optimize liver-protective regimens during the treatment of rheumatic diseases.

CD19-targeted chimeric antigen receptor T-cell therapy in patients with concurrent B-cell Non-Hodgkin lymphoma and rheumatic autoimmune diseases: a propensity score matching study.

Rheumatic autoimmune diseases not only involve the production of autoantibodies but also demonstrate T-cell dysfunction. In patients with concurrent B-cell non-Hodgkin lymphoma (NHL) and rheumatic autoimmune diseases, the safety and efficacy of CD19-targeted chimeric antigen receptor (CAR) T-cell therapy are unknown. Using an aggregated electronic health record database, patients with rheumatic autoimmune diseases (auto group) were compared to propensity score-matched patients without rheumatic autoimmune diseases (non-auto group). From 1/2019 to 1/2023, 58 (4.3%) of 1,363 patients who received CD19-targeted CAR T-cell therapy had concurrent rheumatic autoimmune diseases. Both groups had similar incidence, severity, and management of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Moreover, the two groups had similar time-to-next treatment or death (hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.60 to 1.59, log-rank p = 0.91) and overall survival (HR 0.90, 95%CI 0.46 to 1.78, p = 0.76). Following CAR T-cell infusion, patients with rheumatic autoimmune diseases achieved decreased inflammatory markers, seronegative conversion of autoantibodies, as well as reduced use of steroids and disease-modifying anti-rheumatic drugs. In conclusion, the safety and efficacy of CAR T-cell therapy were not affected in patients with rheumatic autoimmune diseases. Moreover, they achieved better biochemical control of underlying rheumatic diseases.

Knowledge, attitudes, practices, and compliance of rheumatic disease patients toward COVID-19 during the late pandemic

BackgroundRheumatic disease (RD) patients are liable for severe coronavirus disease 2019 (COVID-19). It is noticeable that RD patients’ practices have changed during the late COVID-19 pandemic. This study aimed to assess the knowledge, attitudes, practices, and compliance of RD patients during the late pandemic.ResultsThis study included 188 patients with various RDs. The majority were female (61.7%) and were rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) patients (40.4% and 30.9%, respectively). We found knowledge deficiencies regarding some symptoms, contact isolation, and transmission. Negative attitudes toward COVID-19 final control were detected in a large proportion (50%). Furthermore, the majority did not think they were at risk of COVID-19 due to either RD (61.7%) or their drugs (66%). Their practices were also negative; the majority stopped wearing masks (56.4%) and went to crowded places recently (83%). Moreover, most did not stop or reduce their drugs for fear of COVID-19 but for availability issues (5.3% and 9.6% vs. 37.2%). Male gender and higher education and socioeconomic levels were significantly associated with better knowledge. In addition, RDs such as reactive arthritis, steroid use, lower steroid doses, COVID-19 vaccination, high education and socioeconomic levels, and Internet use as main knowledge sources had a significant association with better attitudes. Conventional disease-modifying anti-rheumatic drugs (DMARDs) use, biologics non-use, high education, severe functional impact, and compliance before the pandemic were significantly associated with higher practice scores. Knowledge was positively correlated with attitudes and practice (P = 0.0001 and 0.003, respectively). Moreover, attitudes were negatively correlated with age (P = 0.016). In multiple linear regression analysis, education, socioeconomic status, and practice were significant positive predictors of knowledge (P = 0.002, 0.001, and 0.046, respectively). Good knowledge, COVID-19 vaccination, younger age, and lower steroid doses were significant predictors of better attitudes (P = 0.02, 0.001, 0.02, and 0.002, respectively). Furthermore, non-use of biologics and functional disability were significant predictors of good practice (P = 0.002 and 0.015, respectively).ConclusionImproving knowledge and educating RD patients about the importance of protective measures is essentially needed to decrease the pandemic fatigue consequences and prevent serious COVID-19 complications in those patients.

Role of inflammatory burden and treatment on joint space width in psoriatic arthritis—a high-resolution peripheral quantitative computed tomography study

BackgroundTo investigate the relationship between disease-related parameters and joint space width (JSW) on high-resolution peripheral quantitative computed tomography (HR-pQCT) in psoriatic arthritis (PsA) patients.MethodsPsA patients who underwent HR-pQCT examination of the second to fourth metacarpophalangeal joint (MCPJ 2–4) were recruited in this cross-sectional study. The joint space metrics included joint space volume (JSV), mean, minimum, and maximum JSW, JSW asymmetry, and distribution. Correlation analysis and multivariable linear regression models were used to determine the association between disease-related variables and JSW.ResultsSixty-seven patients [37 (55.2%) males; median (IQR) age: 57.0 (53.0, 63.0); median disease duration: 21 (16, 28) years] were included in this analysis. Multivariable linear regression analysis demonstrated that males had larger JSV (MCPJ 2–4), mean (MCPJ 4), and maximum JSW (MCPJ 3). Longer disease duration (MCPJ 2–3) and higher ESR values (MCPJ 3) were negatively associated with mean and maximum JSW, while higher damage joint count was negatively associated with mean and minimum JSW (MCPJ 2). Use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) was negatively associated with minimum JSW (MCPJ 3) while use of biologic DMARDs (bDMARDs) was positively associated with minimum JSW (MCPJ 2).ConclusionHigher inflammatory burden as reflected by longer disease duration, higher ESR levels, and damage joint count was negatively associated with mean, maximum, and minimum JSW, while suppression of inflammation using bDMARDs seems to limit the decline in JSW.

Treatment Patterns and Healthcare Resource Utilization Among Newly Diagnosed Psoriasis, Psoriatic Arthritis, Axial Spondyloarthritis, and Hidradenitis Suppurativa Patients with Past Diagnosis of an Inflammatory Condition: A Retrospective Cohort Analysis of Claims Data in the United States.

Psoriasis (PSO), psoriatic arthritis (PsA), axial spondyloarthritis (axSpA), and hidradenitis suppurativa (HS) are chronic inflammatory diseases (CIDs) often diagnosed and treated individually. However, genetic overlaps exist among CIDs, and patients with one are at risk of developing others within the same spectrum. This analysis characterized treatment patterns along with clinical and economic burdens of newly diagnosed CIDs among patients with an additional past diagnosis of PSO, PsA, axSpA, or HS. This study used MarketScan® databases to examine demographics, treatment patterns, and healthcare resource utilization for patients with ≥ 1claim for PSO or HS or ≥ 2claims for PsA or axSpA, and continuous enrollment in the year before (baseline period) and following (follow-up period) the date of first diagnosis (incident diagnosis). Comorbidities and new CID diagnoses with a past diagnosis of PSO, PsA, axSpA, or HS, were examined. The analysis included 298,794 patients (maximum of 1202 patients with ≥ 1 incident diagnoses): 134,233 had incident PSO; 9914 had incident PsA; 115,194 had incident axSpA; and 40,655 had incident HS. Prevalence of ≥ 1 CID diagnosis among patients with past diagnosis of PSO, PsA, axSpA, or HS was 4959/134,233 (3.7%), 5256/9914 (53.0%), 3205/115,194 (2.8%), and 1180/40,655 (2.9%), respectively. In patients with incident axSpA and past PsA diagnosis, incident axSpA and past HS diagnosis, and incident HS and past PSO diagnosis, steroid and opioid use were high across baseline and follow-up periods and use of biologic disease-modifying antirheumatic drugs increased from baseline to follow-up. Disease-related costs increased absolutely and increased or remained high as a proportion of all-cause costs. Patients with newly diagnosed CIDs and additional past diagnosis of PSO, PsA, axSpA, or HS experienced high treatment utilization and healthcare costs. These findings highlight the need for payers, health technology assessment agencies, clinicians, and other stakeholders to explore the co-management of CIDs, rather than treating them separately.
