: The development of biosimilar drugs has revolutionized the management of patients with inflammatory bowel diseases (IBD), significantly reducing healthcare costs. However, the impact of biosimilar availability on patient care is unknown. We conducted a survey to investigate the benefits of using biosimilars in patients with IBD. : Physicians involved in the IBD care were invited to participate in an anonymous online survey. The questionnaire consisted of 42 questions addressing availability, cost, recommendations, and positioning regarding the use of biosimilars. : A total of 233 physicians (88.4% gastroenterologists) from 63 countries worldwide participated in the survey. Most respondents had >10 years of practice (202/233, 85.9%). Biosimilars were available in almost all cases (221, 94.8%), and over two-thirds of respondents had more than one biosimilar of adalimumab or infliximab on hospital formulary. In most cases, adalimumab and infliximab biosimilars had a reduced cost of at least 30% compared to the originators. The savings resulting from the use of biosimilars allowed physicians to improve patient care (3/233, 1.3%) or to improve research (2/233, 0.8%) in only a few cases. Interestingly, for about 50% of respondents, the cost of biologics was a limitation for patient access to therapy. For the majority of participants, the availability of biosimilars did not influence treatment decisions in Crohn's disease (70/165, 42.4%) and ulcerative colitis (83/165, 50.3%). : The reduced cost of biosimilars compared to reference products is the main driver of choice in IBD. The impact of biosimilars of ustekinumab and vedolizumab in improving access to therapies and changing the treatment algorithm remains to be defined.

Canadian Journal of Ophthalmology.... Jun 2024To study the clinical characteristics and long-term outcomes of patients with noninfectious uveitis (NIU) who are treated with systemic immunomodulatory therapy (IMT).
OBJECTIVE
To study the clinical characteristics and long-term outcomes of patients with noninfectious uveitis (NIU) who are treated with systemic immunomodulatory therapy (IMT).
DESIGN
Retrospective case series.
PARTICIPANTS
All consecutive cases of adults with NIU under the care of 5 uveitis subspecialty tertiary care clinics between 2010 to 2021 were included.
METHODS
Patient outcomes were assessed at initial presentation and at the latest available follow-up.
RESULTS
A total of 418 NIU patients receiving IMT therapy with a median age of 46.0 years and 59.3% female were identified. Each patient required an average of 1.4 agents until achieving an optimal response. Following initial treatment with prednisone, patients were most commonly initiated on methotrexate. The top 3 treatments with the highest proportion of optimal treatment response when taken alone or in combination with other agents were infliximab (79.3%), cyclosporine (75%), and adalimumab (70%). The strongest predictors for requiring a greater number of IMTs trialed were younger age, panuveitis, and a chronic or recurrent disease course. Multivariable linear regression analysis suggested that baseline visual acuity at diagnosis was the only significant predictor of final visual acuity (p < 0.001).
CONCLUSIONS
NIU patients on IMT are often trialed on multiple therapeutic agents before achieving an optimal treatment response. Visual acuity at diagnosis is a predictor of final visual outcomes, whereas chronic or recurrent disease course, younger age, and panuveitis are predictors of requiring multiagent treatment regimens.

The treatment landscape for psoriatic arthritis (PsA) has evolved significantly with the introduction of biologic therapies, such as adalimumab, which effectively inhibits tumor necrosis factor-alpha (TNF-α) activity. However, despite their efficacy in controlling inflammation, biologic therapies are associated with heightened risks of infectious complications and malignancies. We present a case of a 66-year-old female with PsA treated with adalimumab who presented with recurrent systemic bacterial infections. Despite attempts to adjust dosing intervals to minimize infection risks, the patient experienced severe complications, including urosepsis, endocarditis, and liver abscesses. The dilemma arises in balancing PsA control with anti-TNFα therapy while minimizing infection risks. Current evidence supporting prophylactic antibiotics in such cases is limited, and determining the next steps for treatment involves challenging decisions such as withholding TNF inhibitors or switching to alternative immunomodulators. This case underscores the need for further research into prophylactic treatment and monitoring protocols to manage recurrent infections during anti-TNF-α therapy effectively.

Frontiers in Pharmacology 2024To compare the effects of tofacitinib and adalimumab on the risk of adverse lipidaemia outcomes in patients with newly diagnosed rheumatoid arthritis (RA).
OBJECTIVE
To compare the effects of tofacitinib and adalimumab on the risk of adverse lipidaemia outcomes in patients with newly diagnosed rheumatoid arthritis (RA).
METHODS
Data of adult patients newly diagnosed with RA who were treated with tofacitinib or adalimumab at least twice during a 3-year period from 1 January 2018 to 31 December 2020, were enrolled in the TriNetX US Collaborative Network. Patient demographics, comorbidities, medications, and laboratory data were matched by propensity score at baseline. Outcome measurements include incidental risk of dyslipidemia, major adverse cardiac events (MACE) and all-cause mortality.
RESULTS
A total of 7,580 newly diagnosed patients with RA (1998 receiving tofacitinib, 5,582 receiving adalimumab) were screened. After propensity score matching, the risk of dyslipidaemia outcomes were higher in the tofacitinib cohort, compared with adalimumab cohort (hazard ratio [HR] with 95% confidence interval [CI], 1.250 [1.076-1.453]). However, there is no statistically significant differences between two cohorts on MACE (HR, 0.995 [0.760-1.303]) and all-cause mortality (HR, 1.402 [0.887-2.215]).
CONCLUSION
Tofacitinib use in patients with RA may increase the risk of dyslipidaemia to some extent compared to adalimumab. However, there is no differences on MACE and all-cause mortality.

Review
BACKGROUND
We present a rare case of NeuroBehcet's-related intracranial hypertension without cerebral venous thrombosis (NBrIHwCVT), occurring as the first presentation of NeuroBehcet's. In addition, we describe the novel use of subcutaneous tocilizumab for this indication. This is followed by a review of the literature on this topic.
CASE
The patient was a 28-year-old lady of Southern Chinese origin with a known history of Behcet's disease with oral ulcers and ocular findings for which she was on mycophenolate mofetil and adalimumab. She presented with a headache and bilateral disc swelling associated with an intracranial pressure (ICP) of > 40cmH20. There were no structural lesions or cerebral venous thrombosis (CVT) on imaging. Initial lumbar puncture had raised leucocytes and protein. We discuss diagnostic challenges given persistently elevated ICP despite subsequent non-inflammatory cerebrospinal fluid (CSF) profiles and non-response to acetazolamide. She eventually showed a response to immunosuppressant therapy in the form of pulsed methylprednisolone, cyclophosphamide and subsequently subcutaneous tocilizumab, supporting the diagnosis of NBrIHwCVT. Complete normalization of ICP remains challenging. Her disease course was severe, unusual for her ethnicity.
LITERATURE REVIEW
We identified 34 patients (including ours) from 14 publications. We found that the majority of NBrIHwCVT patients were young (average age of 34 years), with a slight female preponderance. Of the 17 cases in the literature with available data on CSF profile, none had raised leucocytes whilst one patient had elevated protein. Patients were generally treated with steroids and occasionally azathioprine, in line with the suspected autoimmune pathophysiology. Of 22 patients with data on outcome, six (27%) were noted to have recurrence of symptoms generally occurring a few months later.
CONCLUSION
As demonstrated by this case, NBrIHwCVT can present with BD with raised ICP even if there is no prior history of NB, central Asian ethnicity, cerebral venous thrombosis or features of inflammation on the CSF. We demonstrated how novel use of Tocilizumab may have a role in the management of NBrIHwCVT. Based on our literature review, patients were more likely to be young, female, display a non-inflammatory CSF picture, be treated with steroids and harbour a possibility of recurrence.

Review
To explore the effectiveness and safety of upadacitinib for managing axial spondyloarthritis. Four databases (PubMed, EMBASE, Cochrane, and Web of Science) were applied to search randomized controlled trials (RCTs) for assessing upadacitinib treatment for axial spondyloarthritis published until January 2024. Five RCTs involving 1,246 participants were included. The upadacitinib group had significantly higher percentages of participants achieving Assessment of spondyloarthritis international society (ASAS) 20, ASAS40, ASAS partial remission, Bath ankylosing spondylitis disease activity index (BASDAI) 50, Ankylosing Spondylitis Disease Activity Score (ASDAS) low disease activity, ASDAS inactive disease, ASDAS clinically important improvement, and ASDAS major improvement, except for Work Productivity and Activity Impairment (WPAI) absenteeism. Obvious improvements were observed in the upadacitinib group for ASDAS (CRP), BASDAI, Modified BASDAI, Bath Ankylosing Spondylitis Functional Index (BASFI), Canadian Spondyloarthritis Research Consortium (SPARCC) MRI spine, SPARCC MRI sacroiliac joint, Ankylosing Spondylitis Quality of Life (ASQoLS), ASAS Health Index, Bath Ankylosing Spondylitis Metrology Index (BASMI), Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), Total Back Pain, Nocturnal Back Pain, WPAI overall work impairment, WPAI presenteeism, and WPAI activity impairment. Adverse events (AEs) and serious adverse events (SAEs) incidence rates showed no significant difference differ between upadacitinib and placebo groups. Subgroup analysis revealed that disease subtype and age did not significantly affect efficacy, and upadacitinib demonstrated comparable efficacy to adalimumab for axial spondyloarthritis. Upadacitinib exhibited satisfactory efficacy in treating axial spondyloarthritis, reducing disease activity and significantly enhancing patients' physical function, emotional well-being, and social engagement. This meta-analysis offers robust evidence supporting upadacitinib as a new treatment for axial spondyloarthritis patients.

Observational Study
Impact of a Patient Support Program on time to discontinuation of adalimumab in Australian adult patients with immune-mediated inflammatory diseases-an observational study.
This observational study evaluated the impact of a sponsor company-provided Patient Support Program (PSP) on discontinuation of adalimumab in adult Australian patients eligible for Pharmaceutical Benefit Scheme (PBS)-reimbursed adalimumab for Rheumatoid Arthritis (RA), Ankylosing Spondylitis (AS), Psoriatic Arthritis (PsA), Crohn's Disease (CD), Ulcerative Colitis (UC), or Hidradenitis Suppurativa (HS). Patients initiating adalimumab between May 2018 and September 2019 were enrolled into two prospective cohorts based on their decision to opt for or decline the PSP (PSP or non-PSP cohorts). In addition, a historical, retrospective Non-PSP cohort was established from the Services Australia 10% PBS dataset by extracting data of patients initiating adalimumab prior to the introduction of adalimumab PSPs and based on adalimumab PBS listing dates (AS: April 2007 to March 2009; PsA/RA: January 2007 to December 2008; CD: January 2009 to December 2010; HS and UC indications not included). Follow-up for all cohorts was 12 months. The primary endpoint was the time to discontinuation, compared between the prospective PSP cohort and the prospective or retrospective Non-PSP cohort. Inverse probability of treatment weighting was used to balance the cohorts. A Cox proportional hazards model indicated no difference in time to discontinuation between the prospective PSP (n = 162) and non-PSP (n = 65) cohorts (HR [95% CI] = 1.256 [0.616-2.563], p = 0.5304). The 12-month adalimumab persistence rates (95% CI) were 78% (69%, 84%) and 82% (67%, 90%), respectively. In contrast, discontinuation was less likely in the prospective PSP (n = 151) compared with the retrospective non-PSP (n = 297) cohort (HR [95% CI] = 0.44 [0.28-0.68], p<0.001). The 12-month persistence rates (95% CI) were 81% (76%, 90%) and 61% (56%, 67%), respectively. Overall, this study suggests that optimal adalimumab persistence can be achieved with either a structured PSP or healthcare support from other sources, but this was not the case more than a decade ago.

Review
PURPOSE
Tuberculous meningitis (TBM) causes significant morbidity and mortality in young children. Early treatment can be initiated with magnetic resonance (MR) imaging diagnosis. We present MR-detectable miliary meningeal TB in two patients. CASE 1: A 9-year-old girl developed fevers, cough, lethargy, and seizures. Brain MRI demonstrated multiple, small, T2-dark, rim-enhancing lesions, associated with cranial nerve and leptomeningeal enhancement. CSF showed pleocytosis, low glucose, and high protein. Chest CT showed mediastinal lymphadenopathy, multiple small interstitial lung nodules, and a splenic hypo enhancing lesion. Serial bronchoalveolar lavage studies were Xpert MTB/RIF and acid-fast negative. Endobronchial US-guided biopsy of a subcarinal lymph node was positive for Xpert MTB PCR. She was started on a 4-drug treatment for TBM and dexamethasone. Contact tracing revealed a remote positive contact with pulmonary tuberculosis. CASE 2: A 17-year-old female with Crohn's disease on adalimumab developed refractory ear infections despite multiple courses of antibiotics. She underwent myringotomy, with negative aerobic ear fluid culture. Brain MRI, obtained due to persistent otorrhea, showed multiple, small, round, T2-dark lesions. CSF studies were normal. CT chest, abdomen, and pelvis to assess for disseminated disease showed left upper lobe tree-in-bud nodules, hypoattenuating splenic lesions and a left obturator internus abscess with adjacent osteomyelitis. She underwent CT-guided aspiration of the obturator muscle collection, bronchoscopy with bronchoalveolar lavage, biopsy of two preexisting chronic skin lesions, and ear fluid aspiration. QuantiFERON Gold was positive. Ear fluid was Xpert MTB/RIF assay and acid-fast stain positive. Cultures from the ear fluid, skin tissue, muscle tissue, and alveolar lavage showed growth of acid-fast bacilli. She was started on 4-drug therapy and prednisone.
CONCLUSION
Our cases highlight that TBM in many cases remains a diagnostic dilemma - both our patients presented in a prolonged atypical manner. The term miliary TB not only refers to a pattern of interstitial nodules on chest radiographs but also indicates the hematogenous spread of the disease and concurrent pulmonary and extrapulmonary involvement with high risk of TB meningitis. We promote the use of the term miliary meningeal TB - in both cases, the neuroimaging diagnosis of TB preceded both chest imaging and laboratory confirmation of the disease. Miliary meningeal nodules on MRI may have characteristic T2 low signal and may be more conspicuous in children and immunocompromised individuals where background basal meningeal enhancement is less prominent.

Journal of Atherosclerosis and... Jun 2024Evidence regarding the association between various tumor necrosis factor-α (TNF-α) inhibitors and cardiovascular adverse events (AEs) is both limited and contradictory.
AIM
Evidence regarding the association between various tumor necrosis factor-α (TNF-α) inhibitors and cardiovascular adverse events (AEs) is both limited and contradictory.
METHODS
A retrospective pharmacovigilance study was conducted using the FDA Adverse Event Reporting System (FAERS) database. Cardiovascular AEs associated with TNF-α inhibitors (adalimumab, infliximab, etanercept, golimumab, and certolizumab) were evaluated using a disproportionality analysis. To reduce potential confounders, adjusted ROR and subgroup analyses were performed.
RESULTS
After excluding duplicates, 9,817 cardiovascular reports were associated with the five TNF-α inhibitors. Only adalimumab had positive signals for myocardial infarction (ROR=1.58, 95%CI=1.51-1.64) and arterial thrombosis (ROR=1.54, 95%CI=1.49-1.58). The remaining four TNF-α inhibitors did not show a risk association with any type of cardiovascular event. Further analyses of specific indication subgroups and after adjusting for any confounding factors demonstrated that adalimumab was still significantly associated with cardiovascular events, especially in patients with psoriasis (adjusted ROR=2.16, 95%CI=1.95-2.39).
CONCLUSIONS
This study revealed that adalimumab was the only TNF-α inhibitor associated with an elevated risk of thrombotic cardiovascular AEs, whereas the other four TNF-α inhibitors did not show any risk effect. However, given the limitations of such pharmacovigilance studies, it is necessary to validate these findings in prospective studies in the future.
