Real-World Treatment Patterns and Healthcare Resource Use for Ulcerative Colitis and Crohn's Disease in Italy.

INTRODUCTION: Real-world data are used to inform decision-makers and optimise therapeutic management for patients with ulcerative colitis (UC) and Crohn's disease (CD). We analysed data on the epidemiology (by using proxies of prevalence and incidence), patient characteristics, treatment patterns and associated healthcare direct costs for the management of patients with UC and patients with CD in Italy. METHODS: This retrospective observational study used administrative databases from eight Local Health Units geographically distributed across Italy. Adult patients with a hospitalisation and/or an exemption for UC or CD were included. Study outcomes were summarised descriptively, and limited statistical tests were performed. RESULTS: At baseline, 9255 adults with UC and 4747 adults with CD were included. Mean (standard deviation) age at inclusion was 54.0 (18.4)/48.6 (18.1) years, for UC/CD. The estimated average incidence of UC and CD for the period 2013-2020 was 36.5 and 18.7 per 100,000, respectively. The most frequently prescribed drug category for patients with UC/CD was conventional treatment [mesalazine and topical corticosteroids (67.4%/61.1%), immunomodulators and systemic corticosteroids (43.2%/47.7%)], followed by biologic treatments (2.1%/5.1%). The mean annual total direct cost per patient was 7678 euro (€), for UC and €6925 for CD. CONCLUSION: This analysis, carried-out in an Italian clinical setting, may help to optimise therapy for patients with UC and CD and provide relevant clinical practice data to inform decision-makers.

Data from clinical practice can be used to guide healthcare decisions and optimise treatment for patients with ulcerative colitis and Crohn's disease. This study used anonymised patient information from almost four million individuals across Italy to describe the epidemiology, patient characteristics, treatment patterns and healthcare costs of patients with ulcerative colitis and Crohn's disease. Adults with an Italian National Health System code in their records associated with the diagnosis of ulcerative colitis or Crohn's disease were included. Baseline characteristics were balanced between groups and rates of perceived incidence were numerically similar to the results reported in similar Italian studies. This study found that patients with ulcerative colitis and Crohn's disease were most often prescribed conventional treatments, and biological treatments were least-commonly prescribed. More than half of patients with ulcerative colitis and nearly half of those with Crohn's disease were persistent with first (index) treatment of mesalazine and topical corticosteroids and with biologic index treatment during the follow-up period. Switch occurred in up to approximately a quarter of patients with ulcerative colitis and Crohn's disease. The main factors that predicted switch were index biologic for ulcerative colitis and baseline comorbidities for Crohn's disease. The average direct cost per patient in 1 year was 7678 euro (€) for ulcerative colitis and €6925 for Crohn's disease. The results of this analysis may help to optimise therapy for patients with ulcerative colitis and Crohn's disease, and to inform decision-makers in healthcare systems on which treatment options provide value for money and benefit patients.

Efficacy and safety of baricitinib in 446 patients with rheumatoid arthritis: a real-life multicentre study.

OBJECTIVES: Baricitinib, an oral Janus kinase (JAK) 1-2 inhibitor, is currently used along biologic DMARDs (bDMARDs) after the failure of methotrexate (MTX) in rheumatoid arthritis (RA). We investigated the efficacy and safety of baricitinib in real life. METHODS: We prospectively enrolled 446 RA patients treated with baricitinib from 11 Italian centres. Patients were evaluated at baseline and after 3, 6, and 12 months. They were arrayed based on previous treatments as bDMARD-naïve and bDMARD-insufficient responders (IR) after the failure or intolerance to bDMARDs. A sub-analysis differentiated the effects of methotrexate (MTX) and the use of oral glucocorticoids (OGC). RESULTS: Our cohort included 150 (34%) bDMARD-naïve and 296 (66%) bDMARD-IR patients, with 217 (49%) using baricitinib as monotherapy. Considering DAS-28-CRP as the primary outcome, at 3 and 6 months, 114/314 (36%) and 149/289 (51.6%) patients achieved remission, while those in low disease activity (LDA) were 62/314 (20%) and 46/289 (15.9%), respectively; finally at 12 months 81/126 (64%) were in remission and 21/126 (17%) in LDA. At all-timepoints up to 12 months, bDMARDs-naïve patients demonstrated a better clinical response, independently of MTX. A significant reduction in the OGC dose was observed at 3 and 12 months in all groups. The serum positivity for both rheumatoid factors (RF) and anti-citrullinated protein antibodies (ACPA) conferred a lower risk of stopping baricitinib due to inefficacy. Fifty-eight (13%) patients discontinued baricitinib due to adverse events, including thrombotic events and herpes zoster reactivation. CONCLUSIONS: Real-life data confirm the efficacy and safety profiles of baricitinib in patients with RA and provide evidence that drug survival is higher in bDMARDs-naïve and seropositive patients.

COVID 19: a clue from innate immunity.

The recent COVID-19 pandemic has had a significant impact on our lives and has rapidly expanded to reach more than 4 million cases worldwide by May 2020. These cases are characterized by extreme variability, from a mild or asymptomatic form lasting for a few days up to severe forms of interstitial pneumonia that may require ventilatory therapy and can lead to patient death.Several hypotheses have been drawn up to understand the role of the interaction between the infectious agent and the immune system in the development of the disease and the most severe forms; the role of the cytokine storm seems important.Innate immunity, as one of the first elements of guest interaction with different infectious agents, could play an important role in the development of the cytokine storm and be responsible for boosting more severe forms. Therefore, it seems important to study also this important arm of the immune system to adequately understand the pathogenesis of the disease. Research on this topic is also needed to develop therapeutic strategies for treatment of this disease.

One-year effectiveness, retention rate, and safety of secukinumab in ankylosing spondylitis and psoriatic arthritis: a real-life multicenter study.

BACKGROUND: Secukinumab (SEC) is effective for ankylosing spondylitis (AS) and psoriatic arthritis (PsA) in randomized trials, but real-life data are lacking. RESEARCH DESIGN AND METHODS: Real-life, prospective observational study on 169 consecutive outpatients at baseline (T0) and at 6 (T6) and 12 months (T12) after starting SEC (39 AS, 23%; 130 PsA, 77%). RESULTS: Significant improvement was seen at T6 and T12 for all clinical variables, including TJC, SJC, ESR, CRP, DAPSA, ASDAS-CRP, and BASDAI, as well as in patient-reported outcomes like VAS-pain. By multivariable regression analysis, in AS patients high BASDAI at T0 correlated with diagnostic delay (R2 = 0.4; p = 0.009) and peripheral joint involvement (R2 = 0.4; p = 0.04). During follow-up, reduction of BASDAI positively correlated with high ESR (R2 = 0.65; p = 0.04). ASDAS-CRP at T0 positively correlated with high ESR (R2 = 0.34; p = 0.004). Reduction of ASDAS-CRP from T0 to T6 correlated with current smoking status (R2 = 0.42; p = 0.003). In PsA patients, reduction of DAPSA score from T0 to T12 is negatively correlated with the presence of metabolic syndrome (R2 = 0.41; p = 0.0025). SEC was well tolerated; 10 patients discontinued treatment for non-severe adverse events. CONCLUSIONS: Secukinumab is effective and safe in patients with AS and PsA in a real-life setting.

Demographic and clinical differences between ankylosing spondylitis and non-radiographic axial spondyloarthritis: results from a multicentre retrospective study in the Lazio region of Italy.

OBJECTIVES: Axial spondyloarthritides (axSpA) are a group of disorders that share similar pathogenetic mechanisms and clinical picture. The aim of this retrospective multicentric study was to evaluate demographic and clinical differences between ankylosing spondylitis (AS) and non-radiographic axSpA (nr-axSpA) patients. METHODS: Patients from 7 rheumatological centres in the Lazio region of Italy were included from January 1st, 2010 to April 1st, 2018, if they had undergone pelvic and/or spine radiographs or magnetic resonance imaging (MRI). Images were evaluated by one experienced radiologist in each centre who already had the clinical suspicion of axSpA. Clinical and therapeutic data were collected at the last observation visit. Categorical variables were presented with percentages and analysed by Chi squared test. Continuous variables were expressed as mean ± standard deviation and compared using the parametric unpaired t-test or the non-parametric Mann-Whitney U-test, when appropriate. p-values <0.05 were considered significant. RESULTS: 210 axSpA patients were included: 65.2% with AS and 34.7% with nr-axSpA. When comparing the two groups, AS patients had longer disease duration, were older, were more frequently males, had a greater diagnostic delay and a higher body mass index than the nr-axSpA patients (p<0.0001, p<0.0001, p=0.003 p=0.007, and p=0.04, respectively). The peripheral joints of the nr-axSpA patients were more frequently involved, had higher frequency of inflammatory bowel disease, higher C-reactive protein levels and lower frequency of HLA-B27 positivity (p=0.005, p=0.007, p=0.01, and p=0.01, respectively). TNF inhibitors were used in 87.8% patients with AS and 78.3% with nr-axSpA (p=0.04). More fat metaplasia was observed on MRI in the nr-axSpA group than in the AS group at sacroiliac joints (p=0.003), and more backfills were detected in the AS group on spine-MRI (p=0.003). Spine-bone marrow oedema was more prevalent in AS than in nr-axSpA (p=0.04), and more sclerosis and backfill were found in AS (p=0.003 and p=0.01, respectively). CONCLUSIONS: In clinical practice, distinctive features in AS and nr-axSpA patients emerged. Imaging is crucial in guiding the choice of treatment in order to control disease activity and inflammation.

Sixth-month remission as a predictor for twelve-month remission in polymyalgia rheumatica.

OBJECTIVES: To investigate clinical and laboratory prognostic factors of remission after one year of follow-up in patients with polymyalgia rheumatica (PMR) treated with low-dose prednisone. METHODS: In this observational study, in a monocentric Italian Rheumatology Unit, we enrolled eighty-one consecutive PMR patients. Clinical and laboratory tests were performed every 3 months. Clinical remission was defined as the lack of symptoms, while laboratory remission was defined as erythrocyte sedimentation rate ≤40 mm/h and C-reactive protein (CRP) ≤0.5 mg/dl. RESULTS: Thirty-eight patients reached complete (clinical and laboratory) remission after 12 months of follow-up. A significant lower percentage of complete remission was seen in female gender compared to male (33.9 % vs. 78.2%, p=0.0001) at univariate analysis. No significant differences were found at baseline according to response to therapy during follow-up, while CRP values at the sixth month were significantly lower in patients who reached complete remission after one year (median: 0.4 mg/dl vs. 1 mg/dl, p=0.017). CRP<0.5 mg/dl at 6 months was independently associated with complete remission at 12 months in the multivariate analysis. CONCLUSIONS: The sixth month of therapy is a target for the management of PMR because it can help to identify patients at greater risk of exacerbations, who may benefit from a tighter follow-up and more aggressive therapeutic strategy. Higher CRP values at 6 months appear to be associated with a higher risk of longer steroid therapy.

PsA-Disk, a novel visual instrument to evaluate psoriatic arthritis in psoriatic patients: an Italian derma-rheuma multicentre study.

BACKGROUND: Consensus among dermatologists and rheumatologists in the diagnosis and assessment of musculoskeletal diseases in psoriasis (PsO) patients is needed. This study assesses characteristics of musculoskeletal pain in patients with PsO for the presence of psoriatic arthritis (PsA) and evaluation of a novel 16-item visual instrument (PsA-Disk). METHODS: Data were collected from eight dermatological/rheumatological centres across Italy. Patients with PsO completed PEST (Psoriasis Epidemiology Screening Tool) and PsA-Disk questionnaires during the first visit. A rheumatological visit was performed to confirm the presence of PsA. Both validity and reliability of PsA-Disk were assessed. RESULTS: A total of 573 patients with PsO were examined at the first visit, and 120 (21%) were diagnosed with PsA. Patients with PsA compared with patients with PsO (n = 119) presented statistically significant differences for: nail involvement, PEST score ⩾3, higher erythrocyte sedimentation rate (ESR), Nail Psoriasis Severity Index (NAPSI)-feet, NAPSI-(hands + feet) and PsA-Disk scores (73.9 ± 32.1 versus 58.1 ± 39.8, p < 0.001). Patients with PsA with knee arthritis had higher PsA-Disk scores (98.4 ± 26 versus 71.5 ± 31.9, p = 0.006) that were also correlated with number of swollen (r = 0.2, p < 0.05) and tender joints (r = 0.24, p = 0.021), patient (r = 0.4, p < 0.001) and physician-pain-visual analogue scale (VAS; r = 0.33, p < 0.001), patient global assessment (PGA)-VAS (r = 0.23, p = 0.025), physician-health assessment questionnaire (HAQ; r = 0.38, p = 0.011), Disease Activity Score (DAS)-44 (r = 0.25, p = 0.023) and Disease Activity in Psoriatic Arthritis (DAPSA; r = 0.31, p = 0.005). The instrument had excellent reliability in terms of internal consistency (Cronbach's alpha = 0.90) and stability (intraclass correlation = 0.98). Moderate agreement between PsA-Disk and PEST (Cohen's kappa = 0.46) was observed, while construct validity appeared appropriate [PsA + patients: PsA-Disk score (interquartile range; IQR) =71 (50-96); PsA-patients: PsA-Disk score (IQR)=50 (20-90); p < 0.001]. CONCLUSION: PsA-Disk may be considered a valid novel instrument aiding both dermatologists and rheumatologists in the rapid detection and assessment of musculoskeletal disease characteristics.

Differential synovial tissue biomarkers among psoriatic arthritis and rheumatoid factor/anti-citrulline antibody-negative rheumatoid arthritis.

BACKGROUND: Differential 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. METHODS: Thirty-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. RESULTS: At 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). CONCLUSIONS: CD117+ 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.
