Tumor necrosis factor (TNF) inhibitor therapy for inflammatory bowel disease (IBD) has been associated with an increased risk of rheumatoid arthritis and other inflammatory conditions. Our retrospective study did not show an increased risk when compared with non-anti-TNF therapy for IBD.

UNASSIGNED: Safety recommendations for Janus kinase inhibitors (JAKi) issued by the European Medical Agency (EMA) in 2023 could potentially influence treatment patterns for rheumatoid arthritis (RA) drugs, but little is known about the impact of these recommendations in routine clinical care.
UNASSIGNED: We retrospectively analyzed the German RHADAR rheumatology database for adult patients with RA and documentation of a new therapy with a JAKi, tumor necrosis factor inhibitor (TNFi), or interleukin-6 receptor inhibitor (IL-6Ri). Data were grouped into half-yearly intervals from quarter (Q)2/2020 to Q3/2023. The period from Q4/2022 to Q1/2023 immediately followed the initial EMA endorsement of Pharmacovigilance Risk Assessment Committee (PRAC) recommendations and Q2/2023-Q3/2023 immediately followed the direct healthcare provider communication (DHPC) containing the new safety JAKi recommendations.
UNASSIGNED: Between April 1, 2020 and September 23, 2023, 3008 newly initiated therapies for TNFi (1499 [49.8%]), JAKi (1126 [37.4%]), and IL-6Ri (383 [12.7%]) were documented by the treating physicians. JAKi were increasingly used in the first two half-year periods (from 29.7% of these therapies in Q2/2020-Q3/2020 to 46.7% in Q2/2021-Q3/2021; odds ratio [OR] 2.08; p<0.001). The proportion of initiated JAKi therapies decreased significantly after the PRAC recommendations (32.9%; OR vs peak 0.56; p=0.001) and the DHPC letter (26.1%; OR vs peak 0.40; p<0.001). JAKi were more likely to be used as >3rd-line therapy in later time periods.
UNASSIGNED: This exploratory study suggests that EMA safety recommendations for JAKi influenced treatment patterns of RA patients who received JAKi in Germany. Additional studies will be needed to confirm these findings.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory rheumatic disease in children, and adalimumab is one of the primary treatment options. Although it is widely used for inflammatory diseases, there is limited research on its safety and efficacy in patients with psychiatric disorders or in those with inflammatory diseases who also have comorbid psychiatric conditions.
METHODS: We report a 12-year-old adolescent boy who presented with emotional instability for 1 year, exacerbated leading to hospital admission in the past month. Upon detailed evaluation after admission, it was found that the patient\'s emotional fluctuations may be related to the use of Adalimumab. Follow-up after psychiatric inpatient treatment revealed that the patient did not experience emotional excitement again after discontinuing Adalimumab.
CONCLUSIONS: Although tumor necrosis factor-α inhibitors have positive effects on the emotional, cognitive, and physical functions of patients with inflammatory diseases, their use may induce mood swings in patients with comorbid mood disorders. This is particularly important for adolescents with rapid mood changes, where greater caution is required. Further research is necessary to clarify the correlation between the adverse effects of these drugs and their impact on patients with bipolar disorder.

A previously healthy man developed pulmonary symptoms 2 weeks after starting treatment with a tumour necrosis factor (TNF) inhibitor. A negative interferon-gamma release assay (IGRA) test was obtained prior to TNF inhibitor exposure, without consideration of the fact that the patient was already immunosuppressed and had a previous positive IGRA test 17 months earlier. The patient was treated for pneumonia twice but did not achieve remission. His physical health progressively deteriorated over the following months. Malignancy was suspected but not found. Eight months after the onset of symptoms, Mycobacterium tuberculosis was found in samples from mediastinal lymph nodes, and the patient was diagnosed with multidrug-resistant tuberculosis (MDR-TB).This case illustrates the diagnostic challenge of TB, the need to raise awareness of the increased risk of TB in patients treated with TNF inhibitors and the need to increase knowledge regarding the effect of immunosuppressive agents on IGRA tests.

BACKGROUND: Biologic disease-modifying antirheumatic drugs (bDMARD) are often discontinued when a patient with rheumatoid arthritis (RA) is diagnosed with cancer. Our aim was to determine trends in bDMARD utilization in patients with RA and recently diagnosed cancer.
METHODS: We examined two national claims databases to identify adults with RA and recently diagnosed colorectal, lung, or prostate cancer (Optum\'s de-identified Clinformatics® Data Mart Database 2008-2022, and Surveillance, Epidemiology, and End Results Program (SEER) Medicare-linked 2008-2017). We determined time trends in bDMARD and tumor necrosis factor inhibitor (TNFi) prescriptions during the first 3 years after cancer with Cochram-Armitage tests and multivariable logistic regression. Cancer cohorts were analyzed separately.
RESULTS: We included 3595 patients in all six cohorts (in Clinformatics® 503 with colorectal, 468 with lung, and 440 with prostate cancer; in SEER-Medicare 580 with colorectal, 1010 with lung, and 594 with prostate cancer). No significant increase was observed in bDMARD or TNFi utilization over time. Overall, use of bDMARD within the first 3 years of follow-up ranged from 16.7% (Clinformatics® lung cohort) to 29.7% (SEER-Medicare colorectal cohort). The major predictor of bDMARD utilization was prior use in the 3 months before cancer diagnosis (p < 0.001 for all cancers) and earlier cancer stage (p < 0.001 in colorectal and lung cancer and p = 0.05 in prostate cancer).
CONCLUSIONS: Use of bDMARD in patients with RA and recently diagnosed common cancers has not increased since 2008. Additional evidence on the safety of bDMARD in patients with early cancer is needed to ensure appropriate management of their RA. Key Points • Use of bDMARD and TNFi in patients with RA and early colorectal, lung, or prostate cancer has been stable since 2008, with no significant increases over time. • The major determinant of receiving bDMARD after cancer diagnosis was prior treatment with bDMARD in the prior 3 months before cancer. • Patients with advanced cancer stage and distant metastases were less likely to receive bDMARD and TNFi than those at early stages of disease.

OBJECTIVE: This study aimed to evaluate the long-term safety and efficacy profiles of ozoralizumab in patients with rheumatoid arthritis (RA) from the OHZORA, NATSUZORA and HOSHIZORA trials.
METHODS: This study conducted an integrated analysis of the three trials. Patients who completed the OHZORA trial with concomitant treatment of ozoralizumab and methotrexate (MTX) or the NATSUZORA trial without MTX were eligible to participate in the long-term extension HOSHIZORA trial. Safety assessment was performed in the safety analysis set, and the incidence rate per 100 person-year (PY) was calculated for a summary of adverse events (AEs) and AEs of special interests (AESIs). The efficacy was analysed in terms of disease activity index response rates and functional remission.
RESULTS: The OHZORA and NATSUZORA trials enrolled 521 patients, of whom 401 patients entered the HOSHIZORA trial and 279 completed the long-term extension treatment with a mean treatment duration of 200 weeks and total exposure of 1419.34 PY in all enrolled patients. Of the patients, 96.9% demonstrated ≥1 AEs, which is mostly mild to moderate. One death was observed, but no conspicuous AEs emerged and no specific concerns in AESIs were found through the long-term administration. The efficacy assessment revealed the maintained American College of Rheumatology response rates of 20%, 50%, and 70% during the trials.
CONCLUSIONS: This integrated analysis revealed no new safety concerns, and the efficacy was maintained in patients with RA under long-term ozoralizumab administration.

UNASSIGNED: Immune-related epidermal necrolysis (irEN), including Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN), represents a potentially lethal reaction to immune checkpoint inhibitors. An optimal treatment strategy remains undefined. This study evaluates the effectiveness and safety of combination therapy with corticosteroids and tumor necrosis factor inhibitors (TNFi) in treating irEN patients.
UNASSIGNED: In this single-center, prospective, observational study, patients with irEN received either corticosteroid monotherapy or a combination therapy of corticosteroids and TNFi (etanercept for SJS, infliximab for TEN). The primary endpoint was re-epithelization time, with secondary endpoints including corticosteroid exposure, major adverse event incidence, acute mortality rates, and biomarkers indicating disease activity and prognosis. The study was registered at the Chinese Clinical Trial Registry (ChiCTR2100051052).
UNASSIGNED: Thirty-two patients were enrolled (21 SJS, 11 TEN); 14 received combination therapy and 18 received corticosteroid monotherapy. IrEN typically occurred after 1 cycle of ICI administration, with a median latency of 16 days. Despite higher SCORTEN scores in the combination group (3 vs. 2, p = 0.008), these patients experienced faster re-epithelization (14 vs. 21 days; p < 0.001), shorter corticosteroid treatment duration (22 vs. 32 days; p = 0.005), and lower prednisone cumulative dose (1177 mg vs. 1594 mg; p = 0.073). Major adverse event rates were similar between groups. Three deaths occurred due to lung infection or disseminated intravascular coagulation, with mortality rates for both groups lower than predicted. Potential risk factors for increased mortality included continuous reduction in lymphocyte subset counts (CD4+ T cells, CD8+ T cells, natural killer cells) and consistent rises in inflammatory markers (serum ferritin, interleukin-6, TNF-α). Re-epithelization time negatively correlated with body mass index and positively correlated with epidermal detachment area and serum levels of interleukin-6 and TNF-α.
UNASSIGNED: Corticosteroids combined with TNFi markedly promote re-epithelization, reduce corticosteroid use, and decrease acute mortality in irEN patients without increasing major adverse events, offering a superior alternative to corticosteroid monotherapy. Inflammatory markers and lymphocyte subsets are valuable for assessing disease activity and prognosis.

Rheumatoid arthritis is a chronic inflammatory disease, and interstitial lung disease is one of the important extra-articular manifestations. There is limited evidence comparing abatacept (ABA) and tumor necrosis factor inhibitors (TNFi) regarding the risk of mortality among patients with rheumatoid arthritis associated interstitial lung disease (RA-ILD). The aim of this study is to investigate the risk of mortality in patients with RA-ILD treated with ABA compared to TNFi. This retrospective cohort study utilized TriNetX electronic health record database. We enrolled patients who were diagnosed with RA-ILD and had received a new prescription for either ABA or TNFi. Patients were categorized into two cohorts based on their initial prescription. The primary outcome was all-cause mortality, and secondary outcomes were healthcare utilizations, including hospitalization, critical care services, and mechanical ventilation. Subgroup analyses were performed on age, presence of anti-citrullinated peptide antibodies (ACPA), and cardiovascular risk. Among 34,388 RA-ILD patients, 895 were selected for each group (ABA and TNFi) following propensity score matching. The ABA group exhibited a higher all-cause mortality risk. (HR 1.296, 95% CI 1.006-1.671). Subgroup analysis showed a heightened risk of receiving mechanical ventilation in ABA-treated patients aged 18-64 years old (HR 1.853, 95% CI 1.002-3.426), and those with cardiovascular risk factors (HR 2.015, 95% CI 1.118-3.630). Another subgroup analysis indicated a higher risk of mortality among ABA-treated patients with positive-ACPA. (HR 4.138 95% CI 1.343-12.75). This real-world data research demonstrated a higher risk of all-cause mortality in RA-ILD patients treated with ABA compared to TNFi, particularly those aged 18-64 years, lacking cardiovascular risk factors, and positive-ACPA. ABA was associated with an increased risk of mechanical ventilation in patients aged 18-64 years and those with cardiovascular risk factors.

BACKGROUND: There have been concerns about the use of tumor necrosis factor inhibitors (TNFi) for autoimmune disease in patients with recently diagnosed cancer. We assessed the survival of patients with rheumatoid arthritis (RA) and newly diagnosed early breast cancer (BC) treated with TNFi in the first two years after BC diagnosis.
METHODS: We identified patients in two datasets: (1) Optum\'s de-identified Clinformatics® Data Mart Database (CDM), (2) Surveillance, Epidemiology, and End Results program (SEER) and Texas Cancer Registry (TCR) Medicare-linked cohort. We grouped patients according to whether they received TNFi, conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) only, or no DMARDs within 2 years after BC. Outcomes were overall survival (OS) and BC-specific survival (BCSS). We conducted landmark analyses at years 1 and 2, with multivariable Cox regressions using propensity scores for adjustment.
RESULTS: In the first year after BC, 165/970 (17.0%) and 201/1246 (16.1%) patients received TNFi in CDM and SEER/TCR-Medicare respectively. In the 1 year landmark, no significant differences in OS were observed between patients treated with TNFi and patients treated with csDMARDs only in CDM (hazard ratio [HR] = 0.77, 95% confidence interval [CI] 0.42-1.40) or SEER/TCR-Medicare (HR = 0.84, 95% CI 0.54-1.31). BCSS (SEER/TCR-Medicare) was better in patients receiving TNFi than in those receiving csDMARDs only (HR = 0.28, 95% CI 0.08-0.98). In CDM, glucocorticoid therapy had worse OS than those without glucocorticoids (HR = 2.18, 95% CI 1.13-4.18). This was also observed in SEER/TCR-Medicare (not statistically significant). Similar results were observed for the 2 year landmark.
CONCLUSIONS: TNFi treatment during the first two years after early BC was not associated with worse survival.

BACKGROUND: This study compared the clinical effectiveness of switching from tumor necrosis factor inhibitor (TNFi) to upadacitinib (TNFi-UPA), another TNFi (TNFi-TNFi), or an advanced therapy with another mechanism of action (TNFi-other MOA) in patients with rheumatoid arthritis (RA).
METHODS: Data were drawn from the Adelphi RA Disease Specific Programme™, a cross-sectional survey administered to rheumatologists and their consulting patients in Germany, France, Italy, Spain, the UK, Japan, Canada, and the USA from May 2021 to January 2022. Patients who switched treatment from an initial TNFi were stratified by subsequent therapy of interest: TNFi-UPA, TNFi-TNFi, or TNFi-other MOA. Physician-reported clinical outcomes including disease activity (with formal DAS28 scoring available for 29% of patients) categorized as remission, low/moderate/high disease activity, as well as pain were recorded at initiation of current treatment and ≥ 6 months from treatment switch. Fatigue and treatment adherence were measured ≥ 6 months from treatment switch. Inverse-probability-weighted regression adjustment compared outcomes by subsequent class of therapy: TNFi-UPA versus TNFi-TNFi, or TNFi-UPA versus TNFi-other MOA.
RESULTS: Of 503 patients who switched from their first TNFi, 261 were in TNFi-UPA, 128 in TNFi-TNFi, and 114 in TNFi-other MOA groups. At the time of switch, most patients had moderate/high disease activity (TNFi-UPA: 73%; TNFi-TNFi: 52%; TNFi-other MOA: 60%). After adjustment for differences in characteristics at point of switch, patients in TNFi-UPA group (n = 261) were significantly more likely to achieve physician-reported remission (67.7% vs. 40.3%; p = 0.0015), no pain (55.7% vs. 25.4%; p = 0.0007), and complete adherence (60.0% vs. 34.2%; p = 0.0049) compared with patients in TNFi-TNFi group (n = 121). Similar findings were observed for TNFi-UPA versus TNFi-other MOA groups (n = 111).
CONCLUSIONS: Patients who switched from TNFi to UPA had significantly better clinical outcomes of remission, no pain, and complete adherence than those who cycled TNFi or switched to another MOA.
