Efficacy and Safety of Filgotinib in Rheumatoid Arthritis Patients Aged over and under 65 Years (ENANTIA-65)

BACKGROUND

According to recent data, the age of patients could represent an important risk factor for MACE (major cardiovascular events), cancer, and VTE (venous thromboembolism) during treatment with JAK inhibitors in rheumatoid arthritis. We decided to analyze the population involved in the ReLiFiRa study by identifying two groups of patients: 65 years or more and less than 65 years of age, evaluating the efficacy and tolerability of 200 mg of Filgotinib daily.

METHODS

Of the 120 ReLiFiRa patients, 54 were younger than 65 years old and 66 patients were 65 years old or older. The data of efficacy and tolerability of treatment with FIL 200 mg daily for 6 months were evaluated.

RESULTS

After six months of treatment, FIL was effective in both age groups. In both groups, the median values of steroid DAS28, CDAI, ERS, PCR, tender joints, swollen joints, VAS, HAQ, PGA patients, and PGA physicians were reduced with a statistically significant difference comparing these values with the baseline values. The difference in age did not impact the effectiveness of the drug. The lipid profile data also did not demonstrate significant differences between the two age groups; however, the comparison between younger vs. older patients' populations regarding the total cholesterol/HDL ratio and LDL/HDL ratio shows a statistically significant difference: total cholesterol/HDL 3.4 (2.12-3.66) vs. 3.64 (3.36-4.13) p = 0.0004, LDL/HDL 1.9 (0.98-2.25) vs. 2.41 (2.04-2.73) p = 0.0002. There are no differences regarding the atherogenic index (LDL-C/HDL-C) and coronary risk index (TC/HDL-C) compared to baseline.

CONCLUSIONS

After six months of treatment with FIL, the older population group showed a higher level of LDL and a lower level of HDL compared to younger patients. The atherogenic index and coronary risk index are higher in patients aged ≥ 65 years, but interestingly, there were no differences when comparing the 6-month data to baseline values. This condition highlights the impact of typical risk factors that act independently of treatment with Filgotinib.

ReLiFiRa (Real Life Filgotinib in Rheumatoid Arthritis): Retrospective Study of Efficacy and Safety in Common Clinical Practice

BACKGROUND

Filgotinib (FIL) is a selective JAK1 inhibitor with an affinity 30-fold higher than JAK2, approved to treat moderate to severe active rheumatoid arthritis (RA), in adults with inadequate response or intolerance to one or more disease-modifying antirheumatic drugs (DMARDs).

METHODS

We conducted a retrospective, multicentric study in order to evaluate efficacy and safety of FIL 200 mg daily therapy, after 3 and 6 months, in 120 patients affected by RA, managed in Tuscany and Umbria rheumatological centers. The following clinical records were analyzed: demographical data, smoking status, previous presence of comorbidities (Herpes zoster -HZ- infection, venous thromboembolism -VTE-, major adverse cardiovascular events -MACE-, cancer, diabetes, and hypertension), disease duration, presence of anti-citrullinated protein antibodies (ACPA), rheumatoid factor (RF), number of biological failures, and prior csDMARDs utilized. At baseline, and after 3 (T3) and 6 (T6) months of FIL therapy, we evaluated mean steroid dosage, csDMARDs intake, clinimetric indexes (DAS28, CDAI, HAQ, patient and doctor PGA, VAS), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and body mass index (BMI).

RESULTS

At baseline, the mean disease duration was 9.4 ± 7.5 years; the prevalence of previous HZ infection, VTE, MACE, and cancer was respectively 4.12%, 0%, 7.21%, and 0.83%, respectively. In total, 76.3% of patients failed one or more biologics (one biological failure, 20.6%; two biological failures, 27.8%; three biological failures, 16.5%; four biological failures, 10.3%; five biological failures, 1.1%). After 3 months of FIL therapy, all clinimetric index results significantly improved from baseline, as well as after 6 months. Also, ESR and CRP significatively decreased at T3 and T6. Two cases of HZ were recorded, while no new MACE, VTE, or cancer were recorded during the observation time.

CONCLUSION

Despite the limitations of the retrospective study and of the observational period of only 6 months, real-life data on the treatment of RA patients with FIL demonstrate that this Jak inhibitor therapy is safe in terms of CV, VTE events, and occurrence of cancer, and is also effective in a population identified as "difficult to treat" due to failure of previous b-DMARD therapy.

Persistence of remission after lengthening of golimumab in inflammatory joint diseases

OBJECTIVES

In refractory inflammatory joint diseases (IJDs) biological disease-modifying anti-rheumatic drugs (bDMARDs) may achieve remission. EULAR recommends bDMARD tapering when remission persists. However, guidelines on tapering modalities and criteria for patient selection are lacking. We aimed to evaluate remission persistency after lengthening the time between injections of golimumab in patients affected by IJD and to identify any patient or disease characteristics associated to flare after lengthening.

METHODS

Patients affected by rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and juvenile idiopathic arthritis (JIA) treated with golimumab were enrolled in a retrospective observational study. Demographic data, ESR, cRP, DAS28/ BASDAI, were collected at baseline and during the follow-up (T1- defined as a medical check-up after 1 year of treatment or, for patients with longerg exposure, the first medical check-up in 2016, when at our unit we began to experience drug tapering- and T2- 12 months after the lengthening was started). In 22/80 patients in remission at T1, injection time was lengthened.

RESULTS

Eighty patients were enrolled, 34 AS, 33 PsA, 9RA and 4 JIA. At baseline, all had an active disease. At T1, 60/80 patients reached remission and 22/60 patients started tapering. At T2, 20/22 pts (91%) were in remission. At T1 BASDAI was higher (2.2, SD 0.28 vs. 0.58, SD 0.47; p<0.001) in patients who lost remission at T2.Patients who flared recovered remission once taken back to a 28-day interval. 4/38 patients maintained at the standard dose flared up and switched/swapped bDMARD. The difference in retention rate toward patients on reduced dose was not significant.

CONCLUSIONS

Results show that golimumab lengthening is safe and successfully maintains remission. In patients who experienced a flare after lengthening, the standard regimen promptly restored remission.

A Pan-European Review of Good Practices in Early Intervention Safeguarding Practice with Children, Young People and Families: Evidence Gathering to Inform a Multi-disciplinary Training Programme (the ERICA Project) in Preventing Child Abuse and Neglect in Seven European Countries

Child maltreatment has detrimental social and health effects for individuals, families and communities. The ERICA project is a pan-European training programme that equips non-specialist threshold practitioners with knowledge and skills to prevent and detect child maltreatment. This paper describes and presents the findings of a rapid review of good practice examples across seven participating countries including local services, programmes and risk assessment tools used in the detection and prevention of child maltreatment in the family. Learning was applied to the development of the generic training project. A template for mapping the good practice examples was collaboratively developed by the seven participating partner countries. A descriptive data analysis was undertaken organised by an a priori analysis framework. Examples were organised into three areas: programmes tackling child abuse and neglect, local practices in assessment and referral, risk assessment tools. Key findings were identified using a thematic approach. Seventy-two good practice examples were identified and categorised according to area, subcategory and number. A typology was developed as follows: legislative frameworks, child health promotion programmes, national guidance on child maltreatment, local practice guidance, risk assessment tools, local support services, early intervention programmes, telephone or internet-based support services, COVID-19 related good practices. Improved integration of guidance into practice and professional training in child development were highlighted as overarching needs. The impact of COVID-19 on safeguarding issues was apparent. The ERICA training programme formally responded to the learning identified in this international good practice review.

AB1540-HPR NURSING INTERVENTIONS FOR RHEUMATIC MUSCULOSKELETAL DISEASES (RMDS) PATIENTS ON BIOLOGIC THERAPY: A SYSTEMATIC LITERATURE REVIEW (SLR)

Background

The support of the Rheumatology nurse to the management of patients who are affected by RMDs, characterized by remission and recrudescence and chronicity, may be strengthened by the investigation of their unmet needs and the identification of the necessary interventions to the continuity and quality of care.

Objectives

The aim of the present SLR is to identify the main nursing interventions to assure quality care in RMDs patients on biologic therapy.

Methods

Study design: a systematic search was conducted from 1990 to 2020 (01/01/1990- 2020/05/07). Inclusion criteria consisted of 1) patients with RMDs in accordance with American College of Rheumatology classification criteria and the American College of Rheumatology/European League against Rheumatism (ACR/EULAR); 2) in therapy with bDMARDS; 3) adult population > 18 years; 4) primary research only; 6) English language; 7) abstract available; and 8) relative quantitative studies; 9) nursing interventions and/or outcomes. Data sources: Medline, CINAHL, PsycINFO and EMBASE databases were used to search for relevant studies. Review methods: using the predetermined inclusion/exclusion criteria, two independent reviewers (MRM, KEA) screened records selected for eligibility based on titles and abstracts. Records meeting the inclusion criteria were retrieved and full texts were further assessed. Critical Appraisal Skills Program (CASP) tools were used to evaluate the quality of the included studies. Data from 8 studies were extracted independently by the reviewers.

Results

1805 articles were retrieved: after the review process, 8 articles met the inclusion criteria resulting in 1 randomized trial, 1 quasi-experimental study and 6 observational studies. The RMDs patient needs emerged concerning the psychosocial domain, the relationship with healthcare facilities and disease follow up to monitor symptoms. Moreover, three major nursing interventions related to these areas were identified: education, patient-centered care and data assessment.

Conclusion

Rheumatology nurses are part of a multidisciplinary team caring for patients on biologic therapy. Starting with accurate initial and ongoing data collection, rheumatology nurses can plan their interventions focusing primarily on patient education and tailored care based on actual needs. Further studies are necessary for research on aspects of patient-centered nursing care, including tele-nursing and Nursing Sensitive Outcomes in RMDs.

Combination of denosumab and biologic DMARDs in inflammatory muscle-skeletal diseases and connective tissue diseases

OBJECTIVE

Osteoporosis (OP) can complicate the course of rheumatic musculoskeletal diseases (RMDs) and connective tissue diseases (CTDs). Denosumab, a monoclonal antibody against RANK-L, showed beneficial effect in rheumatoid arthritis in inhibiting radiographic progression and erosive burden. We tested the efficacy, safety, and persistence on the treatment of the combination of biologic disease-modifying antirheumatic drugs (bDMARDs)/denosumab versus bDMARD in patients with RMD and CTD.

METHODS

This is a retrospective evaluation of a single center, including patients with RMD/CTD (including rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, systemic sclerosis, and overlap syndromes) treatment with bDMARD/denosumab, compared to age, gender, disease, bDMARD, and conventional synthetic disease-modifying antirheumatic drugs-matched controls.

RESULTS

Twenty-eight bDMARD/denosumab patients and 49 bDMARD patients were eligible. Despite a statistically significant difference during the first-year efficacy (due to the different baseline timepoint), there was no difference in the efficacy profile in the second year of treatment and in the safety profile (including local, systemic, and serious adverse events). Moreover, no statistically significant difference in the persistence of bDMARD treatment over 2 years of evaluation was found. The combination of bDMARD and denosumab was not an independent predictor of disease flare or bDMARD treatment withdrawal.

CONCLUSION

The combination of bDMARD and denosumab does not alter the efficacy and the safety profile of the bDMARD in patients with RMD/CTD. Future studies verifying the radiological disease inhibition could support denosumab use in RMD/CTD other than rheumatoid arthritis, when complicated by OP.

Tumor induced osteomalacia: A single center experience on 17 patients

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome due to a phosphaturic tumor, which overproduces Fibroblast Growth Factor 23 (FGF-23), causing hyperphosphaturia, hypophosphatemia, low 1,25(OH)₂D and osteomalacia. Tumor localization is critical, diagnostic delay ranges from 2.5 to 28 years and to date surgical removal is considered effective treatment. We retrospectively evaluated patients with definite diagnosis of TIO referred to a tertiary Rheumatology Center between September 2000 and May 2020, investigating clinical management and disease outcome. We included 17 patients: 10 (58.8%) were females, mean age at diagnosis was 55.3 ± 13.9 years (mean ± standard deviation), with a diagnostic delay from symptoms onset to tumor detection of 6.6 ± 6.25 years. Biochemical data were: serum phosphorus 1.3 ± 0.4 mg/dL (Reference Range: 2.5-4.6), serum 1,25(OH)₂D 31.8 ± 22.9 ng/mL (RR: 25-86), intact FGF-23, 358.9 ± 677 pg/mL (RR: 25-45); 24 h-Urine Phosphorus was increased in only 2 patients, while tubular reabsorption of phosphate (TRP) was decreased in all patients confirming a renal phosphate wasting. In 2013 ⁶⁸Ga- DOTA-based PET/CT was introduced in routinely practice and diagnostic delay was consistently reduced (from 8.6 ± 7.9 to 4.3 ± 2.4 years). Thirteen patients underwent surgery, one patient underwent radiofrequency ablation; 3 patients, not eligible for surgery, were treated only with supplements of phosphorus and calcitriol. One was started on Burosumab after several unsuccessful surgical attempts. After surgery or ablation, 8 patients had complete remission, 3 TIO persistence, and 3 had overtime relapse. Relapses were observed only in patients who previously underwent closed biopsy. To our knowledge, this is the widest European cohort of TIO patients in the last two decades. We confirm a usual diagnostic delay and recommend a stepwise diagnostic approach. Tumor biopsy is not recommended due to the potential cell spilling. Surgery is generally considered a definitive treatment, even though other approaches have been successful in curing TIO. Active surveillance on possible recurrence is always needed. Burosumab appears a promising therapy.

Intravenous immunoglobulins reduce skin thickness in systemic sclerosis: evidence from Systematic Literature Review and from real life experience

INTRODUCTION

Intravenous immunoglobulins (IVIG) are a new therapeutic approach in systemic sclerosis SSc. An immunomodulatory and antifibrotic activity has been postulated. IVIG are generally well tolerated and have only rare side effects. Our retrospective study focused its attention on SSc, an autoimmune connective tissue disease, characterized by several complications which has a significant impact on patient's quality of life. The pathophysiology comprises fibrotic, vascular and immunological aspects.

AIM

The aim of this study was to verify the effectiveness of IVIG on SSc skin involvement. Moreover, a systematic review of the literature (SLR) of the results obtained to date on the use of Intravenous immunoglobulin (IVIG) in SSc has been also performed.

PATIENTS AND METHODS

The data of 24 patients (21 women, 3 male) with refractory diffuse SSc skin involvement were evaluated (mean age was 52.13 years). IVIG infusion at a dosage of 2 g/Kg body weight for 4 consecutive days/month, was started between 2002 and 2019. Skin involvement was evaluated with the modified Rodnan Skin Score (mRSS) before therapy and then again after 6 and 12 months. To perform the SLR, the PubMed, Medline, Embase, and Web of Science database were searched from 1990 to 2020 (keywords: IVIG, systemic sclerosis). Three assessors (E.A., C.B. & M.M.C) identified the criteria to scan all papers.

RESULTS

From the total SLR (106 results), 17 papers were identified after the separation of the clinical cases from the studies (total number of treated patients 183). The studies were classified according to the organ involvement considered in each study, as well as the prescribed dose (high or low doses), and the therapeutic regimens. In the selected papers, the organs mainly involved were the skin, the gastrointestinal, the joint and the cardiovascular systems. Only in one case, plasmapheresis was associated to IVIG. All papers reported significant reduction of the skin involvement, although generally the strength of the works was limited the lack of control cases or by the low number of patients involved. From the real life experience, a statistically significant reduction of mRSS was obtained at 6 months follow-up (average value of -6.61 ± 5.2, p < 0.001), and it was further maintained with a significant stabilization after 12-months (-11.45 ± 9.63, p < 0.002).

DISCUSSION

This SLR and the data of the retrospective study suggest that IVIG may improve skin involvement reducing mRSS in particular in those patients that were refractory to other standard of care therapies and represents a therapeutic option in patients with concomitant myositis. The literature review revealed encouraging perspectives on the use of this therapy, given the effectiveness found in the selected works.

Management of intrathoracic phosphaturic mesenchymal tumor by nonintubated uniportal video-assisted thoracic surgery in a fragile patient

Background

Phosphaturic mesenchymal tumors are rare neoplasms, frequently presenting with osteomalacia. These neoplasms usually grow at a slow rate and are associated with unspecific symptoms.

Case

In this study, we present the case of a 70‐year‐old woman who had been suffering from musculoskeletal pain, hypophosphatemia, and spontaneous fractures. Positron emission tomography with Gallium showed increase uptake in a subpleural lesion.

Conclusion

The patient underwent surgical excision of the subpleural lesion with a non‐intubated uniportal video‐assisted thoracoscopic surgery approach.

Switching from originator adalimumab to biosimilar SB5 in a rheumatology cohort: persistence on treatment, predictors of drug interruption and safety analysis

Aims:

Medical and non-medical switching strategies have been adopted in Europe in the last few years. We aimed to investigate persistence on treatment with a SB5 Adalimumab (SB5) biosimilar after switching from Adalimumab (ADA) originator among patients with inflammatory rheumatic musculoskeletal diseases (iRMD), identifying possible predictors of drug interruption and describing adverse events.

Method:

iRMD patients previously switched to SB5 after at least 6 months of ADA were enrolled. Data on concomitant medications, disease flares, and persistence on SB5 up to the last available follow up were collected retrospectively. Kaplan–Meier and Cox regression models were used.

Result:

A total of 172 patients (106 females, ADA duration 5.8 ± 3.8 years) were enrolled, including 34 rheumatoid arthritis, 59 psoriatic arthritis, and 61 axial spondyloarthritis patients. In a 10 ± 3 months follow up, 65 (37.8%) patients presented with adverse events, with 46 (26.7%) showing a clinically defined disease flare (no disease activity and patient reported outcomes assessment were available); 24 patients interrupted SB5 permanently (among them, 11 back-switched to ADA and 8 were prescribed a different biological therapy). Probability of persistence on SB5 was 94.7% at 6 months and 85.1% at 12 months. Baseline corticosteroid [hazard ratio (HR) 3.209, 95% confidence interval (CI) 1.193–8.635, p = 0.021] and therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) (HR 2.876, 95% CI 1.229–6.727, p = 0.015), as well as the baseline corticosteroid dose (HR 1.200, 95%CI 1.026–1.403, p = 0.022) were predictors of drug interruption.

Conclusion:

Our data on persistence of treatment and adverse events are in line with previous reports. Further large cohort studies may confirm baseline corticosteroid and NSAIDs use as predictors of SB5 interruption, helping to identify patients at higher risk of failure after switching.

[18F]FDG hypermetabolisms of the spleen and/or bone marrow: indirect signs of bacteremia

Funding Acknowledgements

Type of funding sources: None.

Aim

Recently hypermetabolisms of the spleen and/or bone marrow has been proposed as an indirect sign of infective endocarditis (IE), useful to reinforce the suspicion of IE in the absence of any other infectious, inflammatory, or malignant disease. The purpose of this study is to determine whether hypermetabolisms of the spleen and/or bone marrow are indirect signs of bacteremia rather than of IE, specifically.

Materials and Method

In this work we retrospectively evaluated a series 240 patients who performed between January 2015 to December 2020 [18F]FDG PET/CT (Discovery 710 GE) for suspected infection. In particular, 80 pts had infections from different origin and a positive blood culture (PBC), 80 pts presented localized infection, but negative blood culture (IDBCN) and 80 pts were classified as definite IE (IED) according to the 2015 ESCcriteria. [18F]FDG SUVmax SUVmean in bone marrow, spleen and liver were measured drawind a 14 cm3 regions of interest (ROIs) positioned close to the centers of the spleen and of the right liver lobe, but excluding abscess and/or ischemic lesions., as previously described (Caroline Boursier et al. ; Jordy P.Pijl et al.). BM SUVmax and SUVmean was obtained from ROIs placed on the bodies of each of the five lumbar vertebrae, excluding any damaged vertebra. BM to liver SUV ratios (BLR) and spleen to liver SUV ratios (SLR) were calculated. Kruskal-Wallis tests and the Dunn’s test procedure for multiple comparison were performed using JMP Statistical Discoverytm.

Results

No significant difference among the three groups of SUVmax/mean or in SLR were found. Nevertheless, by grouping patients for the presence of positive blood culture (142 pts) or negative blood culture (98 pts), irrespectively from the final diagnosis a significant associations of SLR was found (p = 0.0070). No significant associations were found with BLR.

Conclusions

Based on our data SLR in seems to represent an indirect signs of bacteremia, rather than IE.

Reporting items for capillaroscopy in clinical research on musculoskeletal diseases: a systematic review and international Delphi consensus

OBJECTIVES

The level of detail included when describing nailfold videocapillaroscopy (NVC) methods varies among research studies, making interpretation and comparison of results challenging. The overarching objective of the present study was to seek consensus on the reporting standards in NVC methodology for clinical research in rheumatic diseases and to propose a pragmatic reporting checklist.

METHODS

Based on the items derived from a systematic review focused on this topic, a three-step web-based Delphi consensus on minimum reporting standards in NVC was performed among members of the European League against Rheumatism (EULAR) Study Group on Microcirculation in Rheumatic Diseases and the Scleroderma Clinical Trials Consortium.

RESULTS

A total of 319 articles were selected by the systematic review, and 46 items were proposed in the Delphi process. This Delphi exercise was completed by 80 participants from 31 countries, including Australia and countries within Asia, Europe, North America and South America. Agreement was reached on items covering three main areas: patient preparation before NVC (15 items), device description (5 items) and examination details (13 items).

CONCLUSION

Based on the available evidence, the description of NVC methods was highly heterogeneous in the identified studies and differed markedly on several items. A reporting checklist of 33 items, based on practical suggestions made (using a Delphi process) by international participants, has been developed to provide guidance to improve and standardize the NVC methodology to be applied in future clinical research studies.

EUREKA algorithm predicts obstetric risk and response to treatment in women with different subsets of anti-phospholipid antibodies

OBJECTIVES

aPL, the serum biomarkers of APS, are the most common acquired causes of pregnancy morbidity (PM). This study investigates the impact of aPL positivity fulfilling classification criteria ('criteria aPL') and at titres lower than thresholds considered by classification criteria ('low-titre aPL') on PM and assesses the effectiveness of low-dose aspirin (LDASA), low molecular weight heparin (LMWH) and HCQ in reducing the probability of PM (PPM).

METHODS

Longitudinal data on 847 pregnancies in 155 women with persistent aPL at any titre and 226 women with autoimmune diseases and negative aPL were retrospectively collected. A generalized estimating equations model for repeated measures was applied to quantify PPM under different clinical situations.

RESULTS

EUREKA is a novel algorithm that accurately predicts the risk of aPL-associated PM by considering aPL titres and profiles. aPL significantly impact PPM when at low titres and when fulfilling classification criteria. PPM was further stratified upon the aPL tests: aCL IgG/IgM and anti-β2-glycoprotein I (β2GPI) IgM, alone or combined, do not affect the basal risks of PPM, an increase occurs in case of positive LA or anti-β2GPI IgG. LDASA significantly affects PPM exclusively in women with low-titre aPL without anti-β2GPI IgG. The LDASA + LMWH combination significantly reduces PPM in all women with low-titre aPL and women with criteria aPL, except those carrying LA and anti-β2GPI IgG. In this group, the addition of HCQ further reduces PPM, although not significantly.

CONCLUSION

EUREKA allows a tailored therapeutic approach, impacting everyday clinical management of aPL-positive pregnant women.

AB0256 BARICITINIB (BARI) VERSUS BIOLOGICS IMPACT ON STEROID TAPERING IN RHEUMATOID ARTHRITIS (RA)

Background:

Biologic and target synthetic disease modifying anti-rheumatic drugs (bDMARDs and tcDMARDs) are recommended to control RA disease activity, pain and steroid use. Following randomized clinical trials (RCTs) and their post-hoc analyses, the Janus Kinase Inhibitor tsDMARDs BARI was superior to reference bDMARD Adalimumab in reducing disease activity, pain and functional disability. In addition, BARI monotherapy also determined more significant pain reduction and functional improvement when compared to Tocilizumab monotherapy (3).

Objectives:

to confirm RCT results in a real-life clinical setting, with focus on disease activity, pain, functional disability and steroid tapering, when comparing BARI to bDMARDs for the treatment of active RA.

Methods:

RA patients starting BARI or a bDMARD for active RA were retrospectively evaluated from June 2019 to June 2020. Disease activity (DAS28CRP, SDAI, CDAI), pain visual analogic scale (pain_VAS), functional disability (HAQ) assessments and mean prednisone dosage (pred_dose) were collected at baseline (BL), 3 months (3M) and 6 months (6M) after BARI/bDMARD initiation. The changes of the outcome measures were evaluated between BL-3M, 3M-6M and BL-6M, as well as between BARI and bDMARDs groups. Finally, we assessed the variables associated with prednisone tapering in the whole population.

Results:

90 out of 100 RA patients evaluated (baseline: age 57±12 years, disease duration 131±100 months, DAS28PCR 4.8±1.0, pain_VAS 61±23 mm, prednisone dose 5.5±5.3 mg) were eligible for the study; 49 received BARI and 41 bDMARDs (17 abatacept, 12 TNF inhibitors, 11 tocilizumab, 1 rituximab). At BL, the two groups did not differ statistically in terms of age, sex, disease duration, disease activity, pain_VAS, previous bDMARD failure or ts/bDMARD naive, concomitant conventional synthetic DMARDs treatment, pred_dose. Both BARI and bDMARDs determined a significant reduction in activity scales and HAQ when comparing BL-3M and BL-6M, with only pain_VAS and pred_dose showing a significant decrease in the 3M-6M interval. When comparing the two groups, BARI showed a significantly higher reduction of pred_dose (-3.2±5.1 vs -1.7±3.7 mg at BL-3M, and -4.1±5.3 vs -1.9±4.6 mg at BL-6M), which was not significant after adjusting for BL pred_dose. No other difference was seen when the two groups, including the numerically higher reduction of pain_VAS in the BARI group (-29±28 vs -20±27 mm at BL-3M and -35±25 vs -30±28 mm at BL-6M comparison). The analysis of the predictors for steroid tapering (Δmean_pred) in the two intervals, showed that BL DAS28PCR, DAS28PCR BL-3M change and BL pred_dose were associated with BL-3M Δmean_pred, while 3M pain_VAS and 3M pred_dose were associated with 3M-6M Δmean_pred.

Conclusion:

Although limited by the small samples and the retrospective nature, our real-life comparison shows similar efficacy of BARI and bDMARDs in terms of disease activity control, functional disability and pain. In addition, the treatment with BARI or bDMARD did not influence the steroid tapering, which was driven mostly by its initial dose, disease activity and pain. Larger real-life multi-center studies are warranted to confirm our results.

POS1495-HPR THE EXPERIENCE OF A RHEUMATOLOGY UNIT DURING THE COVID19 LOCKDOWN: TELEMEDICINE ALLOWS A SAFE FOLLOW UP OF PATIENTS WITH RHEUMATIC DISEASES

Background:

In March this year, most of the routine activities were cancelled during the streaming of the pandemic in Italy. This prompted a pragmatic reorganization of the traditional care model of nursing and medicine, to quickly give an efficient clinical response. During the first phase of the pandemic, outpatient visits dropped by more than 60%, forcefully shifting to telemedicine to assure continuity of care despite the lockdown.

Objectives:

The aim of the present work was to describe the strategy adopted during and immediately after the lockdown to assure the follow up of patients and the maintenance of their treatment in an outpatient “virtual” telemedicine clinic dedicated to RDs.

Methods:

the patient flow to a rheumatology division during the lockdown was evaluated retrospectively from March to September 2020 in accordance with local restrictions, and three periods are described.

Results:

653/913 (71.5%), 542/542 (100%) and 1.048/1.048 (100%) infusion activities scheduled were performed at the centre for daily infusion and pre-infusion assessment, respectively during the 1st, 2nd and 3rd period. In the outpatient clinic during the 1st period, 96.96% of the cases was shifted to Telemedicine, which decreased to 52.45% in the 2nd period; while in the 3rd period, 97.6% of the performances were carried out at the clinic. Diagnostic procedures, such as ultrasound, capillaroscopy, and joint injection were generally postponed during the 1st period, reduced drastically during the 2nd and performed regularly during 3rd period. Ulcer treatment and the Clinical Trial Unit never stopped their activity. The flow of the activity of the outpatient clinic and the day hospital is represented as monthly trends in graph 1 (See Graph 1).

Conclusion:

Our data show the feasibility of Telemedicine in a lockdown condition. Shifting stable patients to Telemedicine has the potentiality to minimize the risk of contagion and allow continuity of care. In the future, the use of Telemedicine for specific clinical uses might assure patient assistance also in non-pandemic conditions.

POS0618 PERSISTENCE OF REMISSION AFTER TAPERING OF GOLIMUMAB IN INFLAMMATORY JOINT DISEASE (IJD)

Background:

In refractory IJD, remission may be obtained with antiTNFa drugs and other biological disease modifying anti-rheumatic drugs (bDMARDs). The last EULAR recommendations suggest tapering of bDMARD when remission persists1. However, best timing and modality of tapering are uncertain and specific knowledge on patients’ characteristics associated to a better outcome is still lacking.

Objectives:

To evaluate the persistency of remission after increasing the interval between injections of Golimumab in a group of patients affected by rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and juvenile idiopathic arthritis (JIA) and to identify any variables associated to disease flare after tapering.

Methods:

Between 2011 and July 2020, 80 patients affected by RA, PsA, AS and JIA treated with Golimumab were enrolled. Their demographic and clinical data, including inflammation (ESR and cRP) and clinimetric indices (DAS28 or BASDAI), were collected at baseline and during the follow up visit (T1). In 22/80 patients that reached clinical remission at T1, the time between Golimumab injections has been prolonged (mean time between injection: 43.7 days); ESR and cRP, DAS28/BASDAI, and time since the start of the tapering (weeks) were evaluated in the next control visit (T2).

Results:

80 patients were enrolled (32 male, mean age 50.6 years +/- 13.91), 34 AS, 33 PsA, 9 RA and 4 JIA. At baseline they have an active disease with a DAS 28 of 4.74+/-0.85 and a BASDAI of 5.23+/- 1.31. At T1, 60/80 patients were in remission (75%), with a mean DAS 28 of 1.84+/- 0.6 and an average BASDAI of 1.32+/-0.6, and 22/60 patients started drug tapering. At T2, 20/22 patients (91%) were in remission, (DAS 28 1.9+/-0.49, BASDAI of 0.8+/- 0, 67). A significantly higher BASDAI was observed at T1, even though in the range of absence of disease activity (2.2, +/- 0.28 vs 0.58, +/- 0.47; p <0.001) in patients who, after extending the therapeutic interval (T1) were no longer in remission at T2. Patients with a flare of disease activity (2/22) were taken back to the 28 days window of Golimumab with a prompt recovery of disease remission. Out of the 38 patients maintained at the standard dose, 4 experienced a disease flare with necessity to switch or swope bDMARD, with a retention rate in this group of 90%. Difference of retention rate between patients on standard vs reduced dose was not statistically significative.

Conclusion:

Tapering of Golimumab was successful in 91% of the cases without flare. Moreover, the prolongation of the increase of the treatment window provided the same result as that obtained in patients that continued in the standard time window. This evidence suggests that the extension of the gap between Golimumab administrations may be feasible and safely applied in practice.

Baricitinib in the treatment of rheumatoid arthritis: clinical and ultrasound evaluation of a real-life single-centre experience

Background:

Ultrasound (US) is useful in monitoring RA patients, with the US7 score allowing grey-scale and power-Doppler (PD) semi-quantitative evaluation of synovitis and teno-synovitis. We evaluated real-life efficacy and safety of Baricitinib, an oral selective JAK1-2 inhibitor, in RA patients using clinical, clinimetric, and US assessments.

Methods:

Disease activity score in 28 joints calculated with C-reactive protein (DAS28-CRP), disease activity score in 28 joints calculated with erythrocyte sedimentation rate (DAS28-ESR), clinical disease activity index (CDAI), simplified disease activity index (SDAI), visual analogue scale (VAS)-pain, health assessment questionnaire (HAQ), COCHIN scale, adverse events (AE), concomitant medications, laboratory parameters, and US7 were performed/recorded at baseline, 1, 3, and 6 months in RA patients starting Baricitinib. Responder/non-responder status was determined according to the EULAR Response Criteria at 3 months. SDAI clinical remission or low disease activity (LDA) were calculated at 3 and 6 months.

Results:

In 43 enrolled patients, a significant improvement in disease activity and US7 components (except tendon PD) and a reduction of steroid dosage were observed. Responders at 3 months showed a significantly higher reduction of CDAI, SDAI, COCHIN scale, VAS-pain, and US7 synovialPD, compared with non-responders. At 3 and 6 months, remission/LDA was achieved by 12.8/53.8% and 21.6/51.3% patients, respectively. The csDMARD co-treatment was independently associated with remission/LDA at 3 months. Safety-related drop-outs were in line with literature data. The steroid dosage was associated with AE development at 6 months.

Conclusion:

The real-life data, also obtained with US evaluation, confirmed the Baricitinib efficacy in RA disease control, as well as the utility of assessment during the follow up of disease activity.

Risk of Malignancy and Biologic Therapy in Rheumatic Inflammatory Diseases: A Single-center Experience

OBJECTIVES

Biologic disease modifying anti-rheumatic drugs (bDMARDs) have significantly improved the care of patients with rheumatic muscle-skeletal disorders (RMDs). Considering their immunosuppressive action, a theoretical increase of malignancy risk has been a major concern in the last few decades. The objective of this study is to analyze the incidence of malignancies in a cohort of patients affected by rheumatoid arthritis (RA), psoriathic arthritis (PsA), and ankylosing spondylitis (AS) treated with bDMARDs.

METHODS

The charts of bDMARD-treated RMD patients were reviewed, and data about bDMARD exposure and malignant cancers (excluding non-melanoma skin cancer) were collected.

RESULTS

921 patients were included (median age: 50.59 years, 66.67% females); 1374 bDMARD treatments were administered, 87.12% were tumor necrosis factor inhibitors. A total of 21 malignant neoplasms were detected in 21 patients (61.90% females, median age at cancer diagnosis: 64.99 years), 66.67% in RA patients, 19.05% in PsA, and 14.28% in AS. Among them, 10 patients (47.62%) were treated with etanercept, 6 patients (28.57%) with adalimumab, and 1 case each with tocilizumab, certolizumab, golimumab, infliximab, and abatacept. The most common malignancies that we found were lung cancers, ductal mammary carcinomas, melanomas, and lymphomas. The incidence rate (IR) of malignancies in our cohort was 3.47 per 1000 person-years (p-y); the higher IRs were in RA patients (5.13 per 1000 p-y), in males (4.21 per 1000 p-y), and in patients aged >70 years (10.14 per 1000 p-y).

CONCLUSIONS

The results of our study showed IR of malignancies in RMD patients treated with bDMARDs that is in agreement with literature data.

The switch from etanercept originator to SB4: data from a real-life experience on tolerability and persistence on treatment in joint inflammatory diseases

Aims:

Switching from originator to biosimilar is part of current practice in inflammatory rheumatic musculoskeletal diseases (iRMDs) such as rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondylarthritis (axSpA), with evidences derived from both etanercept (ETN) to SB4-switching randomized controlled trials and real-life registries. We investigated the safety and treatment persistence of ETN/SB4 in a multi-iRMD cohort derived from two rheumatology departments in our region.

Methods:

Adult patients with iRMDs, treated with ETN for at least 6 months and switched to SB4 in stable clinical condition, were eligible for this retrospective evaluation. Retrospective data on adverse events, loss of efficacy and persistence on treatment were collected until latest available follow-up.

Results:

A total of 220 patients (85 RA, 81 PsA, 33 axSpA, 14 juvenile idiopathic arthritis and seven other conditions; 142 females, mean age 58 ± 7 years, disease duration 12 ± 4 years, ETN duration 7 ± 4 years) were enrolled, with median follow-up of 12.1 (9.7–15.8) months. A total of 50 patients (22.7%) presented with at least one adverse event, with 36 (16.4%) disease flares and 30 (13.6%: 11 for safety and 19 loss of efficacy) SB4 withdrawals. Cumulative SB4 treatment persistence was 99.1%, 88.6% and 64.6% at 6, 12 and 18 months respectively. Back-switch to ETN was performed in 17/30 cases, the remaining cases were managed with change of biologic disease modifying or conventional synthetic anti-rheumatic drug. Age was the only significant predictor of SB4 interruption at 6 months.

Conclusion:

Our real-life data confirm the safety profile of switching from ETN to SB4, with slightly higher treatment persistence rates compared with other real-life registries.

AB0281 SAFETY AND RETENTION RATE AFTER SWITCHING FROM ETANERCEPT ORIGINATOR (ETN) TO ETANERCEPT BIOSIMILAR (SB4) IN INFLAMMATORY JOINT DISEASES: DATA FROM REAL LIFE

Background:

SB4 in now commonly used in the treatment of inflammatory joint diseases, with evidence of efficacy and persistence up to 12 months from switching in both randomized controlled trials in Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) and Ankylosing Spondylitis (AS).

Objectives:

we investigated the safety and retention rate of SB4 at 6, 12 and 18 months after switching from ETN in two rheumatology departments in our region.

Methods:

adult patients with RA, PsA, AS, Juvenile Idiopathic Arthritis (JIA) and other rheumatic diseases treated with ETN for at least 6 months, switched to SB4 in stable clinical conditions, were eligible for this retrospective evaluation. Data on adverse events (in particular infectious events), loss of efficacy (articular, cutaneous, ocular or intestinal disease re-activation) and persistence on treatment were collected since latest available follow-up. Retention rate, reason for discontinuation and subsequent management data were collected at 6, 12, 18 months.

Results:

220 patients (142 females, mean age 58+-7 years, disease duration 12+-4 years, ETN duration 7+-4 years) were enrolled, with median follow up of 12.1 (9.7-15.8) months duration; ETN was used in different biologic DMARDs treatment lines (first 76.8%, second 17.7%, third 3.2 %, fourth 2.3%). Study population was composed of 85 RA, 81 PsA, 33 AS, 14 JIA and 7 other conditions (mostly scleroderma). In the follow-up, 50 patients (22.7%) presented with at least one non-serious adverse event, with 36 (16,4%) disease re-activation (mostly articular) and 30 (13,6% - 11 for safety and 19 loss of efficacy) SB4 interruptions. Retention rates were 99.1 (210/212) at 6, 90.9% (150/165) at 12 and 81.5% (53/65) at 18 months respectively. Back-switch to ETN was performed in 17/30 cases, the remaining cases were managed with change of bDMARD or csDMARD). Age was the only significant predictor of SB4 interruption at 6 months (OR 1.058, 95%CI 1.007-1.112, p=0.026), while disease, bDMARD line, csDMARD combination, gender, disease duration or ETN duration did not influence retention rates at 6, 12 or 18 months.

Conclusion:

our real-life data confirm the safety profile of switching from ETN to SB4. In our patients, the data show a higher retention rate, when compared to other-real life registries data (1,2)

THU0528 NAILFOLD VIDEOCAPILLAROSCOPY REPORTING IN CLINICAL RESEARCH: INTERNATIONAL DELPHI BASED CONSENSUS

Background:

Nailfold capillaroscopy (NVC), a non-invasive technique to assess microcirculation, is increasingly being incorporated into rheumatology routine clinical practice. Currently, the degree of description of NVC methods varies amongst research studies, making interpretation and comparison between studies challenging. In this field, an unmet need is the standardization of items to be reported in research studies using NVC.

Objectives:

To perform a Delphi consensus on minimum reporting standards in methodology for clinical research, based on the items derived from a systematic review focused on this topic.

Methods:

The systematic review of the literature on NVC methodology relating to rheumatic diseases was performed according to PRISMA guidelines (PROSPERO CRD42018104660) to July 22nd2018 using MEDLINE, Embase, Scopus. Then, a three-step web-based Delphi consensus was performed in between members of the EULAR study group on microcirculation in rheumatic diseases and the Scleroderma Clinical Trials Consortium. Participants were asked to rate each item from 1 (not appropriate) to 9 (completely appropriate).

Results:

In total, 3491 references were retrieved in the initial search strategy, 2862 were excluded as duplicates or after title/abstract screening. 632 articles were retrieved for full paper review of which 319 fulfilled the inclusion criteria. Regarding patient preparation before the exam, data were scarce: 38% reported acclimatization, 5% to avoid caffeine and smoking, 3% to wash hands and 2% to avoid manicure. Concerning the device description: 90% reported type of instrument, 77% brand/model, 72% magnification, 46% oil use, 40% room temperature and 35% software for image analysis. As regards to examination details: 76% which fingers examined, 75% number of fingers examined, 15% operator experience, 13% reason for finger exclusion, 9% number of images, 8% quality check of the images and 3% time spent for the exam. Then, a three-round Delphi consensus on the selected items was completed by 80 participants internationally, from 31 countries located in Australia, Asia, Europe, North and South America. Some items reached the agreement at the second round (85 participants), and other items were suggested as important to consider in a future research agenda (e.g. temperature for acclimatization, the impact of smoking, allergies at the application of the oil to the nailbed, significance of pericapillary edema, methods of reporting hemorrhages, ramified and giant capillaries). The final agreement results are reported below:

Conclusion:

On the basis of the available literature the description of NVC methods was highly heterogeneous and individual published studies differed markedly. These practical suggestions developed using a Delphi process among international participants provide a guidance to improve and to standardize the NVC methodology in future clinical research studies.

THU0421 TUMOR-INDUCED OSTEOMALACIA: DATA FROM A MONOCENTRIC EXPERIENCE ON 16 PATIENTS

Background:

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome due to a phosphaturic tumor, which overproduces fibroblast growth factor-23 (FGF-23), causing hyperphosphaturia, hypophosphoremia, low 1,25(OH)2VitD3and osteomalacia. Locating the tumor is critical, because lesions are typically small, benign mesenchymal tumors, anywhere in the body; the delay between onset of symptoms and diagnosis ranges from 2.5–28 years. Surgical removal is the only effective therapeutic approach.

Objectives:

To retrospectively evaluate patients affected by TIO, investigating clinical management and disease outcome.

Methods:

We retrospectively collected data of patients affected by TIO referred to a tertiary Rheumatology Center between Sep 2000 and Jan 2020.

Results:

We included 16 patients with a definite diagnosis of TIO, mean age±standard deviation 62.4±14.6 yrs, 56.2% females, mean age at symptoms onset 48.0±14.3 yrs (53.8±13.1 at diagnosis). Mean diagnostic delay between symptoms onset and tumor detection was 6.8±6.4 yrs. All patients complained bone pain, muscle weakness, and fractures before diagnosis of TIO. Biochemical findings were: mean serum Phosphorus (PS) 1.4±0.4 mg/dL (reference range (RR) 2.5-4.6), mean serum Calcium 9.4±0.7 mg/dL (RR 8.4-10.2), mean serum 1,25(OH)2VitD330.5±23.4 ng/L (RR 25-86). Intact-FGF-23 was dosed in 9 patients, always resulting elevated: mean 396.6±707.3 pg/mL (RR 25-45). PTH was increased in 30% of cases, while serum alkaline phosphatase was increased in 87.5%. 24h-Urine Phosphorus (PU) was increased in only 13% of patients, but, when renal phosphate wasting by tubular reabsorption of phosphate (TRP) was calculated, PU resulted increased in all.

Tumor was localized in all cases (Fig.1) and were localized in bone and soft tissue, by using functional imaging, followed by anatomical techniques. Before the introduction in routinely practice of68Ga-DOTATATE-PET-CT in 2013, Octreoscan-SPECT/CT and18F FDG-PET were used as imaging modalities. Since 2013, diagnostic delay consistently reduced, from 8.6±8.3 yrs (7 patients) to 4.5±2.6 yrs (9 patients), confirming higher diagnostic accuracy of68Ga-DOTATATE-PET-CT.

Figure 1.

13 patients underwent surgery; in two cases surgery was not possible due to tumor location, so pharmacological support with phosphate supplements and calcitriol was started; a patient underwent to TC-guided radiofrequency ablation. After surgery, 7 patients experienced a complete remission, 3 had a persistence of the disease, and 3 an overtime relapse, even after a longstanding normalization of PS (6 years). After surgical tumor removal, PS significantly increased in few days (from 1.36±0.39 to 2.9±1.1, p=0.0001), while iFGF-23 levels tended to rapidly decreased (from 396.6±707.3 to 62.8±78.4). Before the introduction of68Ga-DOTATATE-PET-CT, 6 patients underwent to imaging-guided closed biopsy to confirm tumor localization; by using68Ga-DOTATATE-PET-CT only 2 subjects had closed biopsy. Furthermore, in our population only patients who had biopsy to detect the lesion (7 patients) had relapses compared to patients who did not.

Conclusion:

To our knowledge, this is the widest European cohort of patients affected by TIO reported in the last two decades. We confirm an important delay between symptoms onset and diagnosis. To locate tumor, a stepwise approach is recommended, starting with a thorough medical history and physical examination, followed by functional imaging, preferring68Ga-DOTATATE-PET-CT. Tumor biopsy is not recommended due to the potential cell spilling. Surgery is considered the only definitive treatment, aiming to a wider excision. Active surveillance is always needed, due to the possible relapses, even after a long period of complete clinical and biochemical remission.

THU0360 EFFICACY OF A SELF-TREATMENT PROTOCOL FOR FACE AND TEMPOROMANDIBULAR JOINTS REHABILITATION IN SYSTEMIC SCLEROSIS (SSC)

Background:

In SSc, skin involvement of the face is frequent and extremely disabling, resulting in limited mouth opening, an altered dentition, difficulty in teeth care, as well as having a strong impact on the emotional and psychological well-being, thus impairing quality of life.

Objectives:

to evaluate the efficacy of a self-treatment protocol (created by AMURR A Multidisciplinary Association of Rheumatological Rehabilitation) for face and tempomandibular joints (TMJs) rehabilitation with two devices used in the dental field.

Methods:

40 SSc patients (37 female and 3 male) with a mouth opening ≤ 40 mm, were recruited and randomized in two groups of treatment: Group 1 (20 patients: mean age 50,650 yrs ± 13,937 SD, mean disease duraton 10,45 yrs ± 7,877 SD, opening mouth 32,250 mm ± 5,590 SD) treated with a home self-treatment protocol consisting of 23 exercises carried out at home in front of a mirror, 22/23 exercises were performed once a day, one of these using a device to obtain uniform stretching of the buccal rhyme, another one usingused three times a day to reduce tension of muscles of the TMJs, facilitating the mouth opening; group 2 (20 patients: mean age 58,05 yrs ± 18,103 SD, mean disease duration 17,4 yrs ± 15,017 SD, opening mouth 34,950 mm ± 5,753) without physical rehabilitation, only drugs as treatments of SSc and its complications. All patients underwent a baseline (T0) and 45 days (T1) clinimetric assessment by self-assessment of quality of life with SF-36 (Short-Form 36 Health Survey), of the degree of disability of the mouth with MHISS (of the Mouth Handicap in Systemic Sclerosis scale), Muscle pain evaluated by numerical rating scale (NRS) of the temporomandibular joint with TMD (Temporo mandibular Disorders), evaluation of mouth opening and ROM of the cervical spine. Statistical analysis was performed using the t-test or the Mann-Whitney test for assessing changes in all measurement scales between treatment groups.

Results:

The protocol of home physiotherapy exercises resulted in a statistically significant improvement in the treated group compared to group 2 both for mouth opening (T0: 32,250 ± 5,590, T1: 35,650 ± 6,046) vs (T0: 34,950 ± 5,753 T1: 34,300 ± 6,001) (p<0.001), cervical flexion (T0: 2,950 ± 1,939 T1: 1.700 ± 1,525) vs (T0: 4,450 ± 2,282 T1:4,075 ± 2,238) (p<0.01), cervical extension (T0: 17,025 ± 1,895 T1: 17,625 ± 1,605) vs (T0: 17,050 ± 2,089 T1: 16,525 ± 3,110) (p<0.05), cervical right lateral flexion (T0: 14,075 ± 2,386 T1:13,400 ± 2,431) vs (T0: 14,200 ± 1,765 T1: 14,425 ± 1,742) (p<0.01), cervical right rotation (T0: 14,200 ± 3,416 T1:13,750 ± 3,206) vs (T0: 14,900 ± 1,683 T1: 15,550 ± 2,188) (p<0.01), cervical left rotation (T0: 14,725 ±3,640 T1:14,450 ± 3,710) vs (T0: 15,900 ± 2,614 T1: 16,450 ± 2,964) (p<0.05), mouth disability at MHISS (T0: 19,100 ± 10,356 T1: 16,000 ± 9,989) vs (T0: 20,950 ± 9,950, T1: 21,100 ± 10,775) (p<0.01).

Conclusion:

The use of the home exercises protocol associated with the two devices has shown a significant improvement of the disability linked to skin involvement of the face. This highlights the fundamental role that home rehabilitation self therapy has in practice. These data will need to be confirmed in a larger cohort of patients

AB0239 EFFECTS OF DYSMETABOLISMS AND COMORBIDITIES ON THE EFFICACY, SAFETY AND RETENTION RATE OF BIOLOGICAL DMARDS (bDMARD) IN INFLAMMATORY JOINT DISEASES

Background:

bDMARDs have an effect on glucose homeostasis (1), lipoproteins profile (2; 3) and blood pressure (4). However, with the exception of obesity (5; 6), there are no clear data on how bDMARDs work in patients who already have or develop metabolic comorbidities and whether these conditions can impact on their efficacy and safety profile.

Objectives:

to evaluate, in chronic inflammatory joint diseases, the effect of arterial hypertension (AH), dyslipidemia (DYS) and diabetes mellitus (DM) on efficacy, safety and retention rate of first-line bDMARDs therapy.

Methods:

a retrospective observational study on the clinical charts of Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) or Ankylosing Spondylitis (AS), treated with first on-label bDMARD was performed. Data on adverse events, efficacy and comorbidities at the baseline visit in which the bDMARD was prescribed (BL), the visit performed after 6 months of therapy (6M), and the last visit on treatment (LoT) were collected.

Results:

383 patients (41,8% RA, 33,4% PsA and 24,8% AS) were included in the study, with the predominance of females (F: 67,36%, M: 32,64%; mean age 51,67 ± 15,11 years). Our data show that the presence of comorbidities had no influence on efficacy of bDMARD, while patients who had DYS at BL manifested a higher rate of systemic adverse events either in the first 6 months of therapy (58,9% vs 43,7%, p=0,040) and also later on (80,36% vs. 66,67%, p=0,046). In addition, patients who developed DYS and AH after the 6M visit reported a higher rate of systemic adverse events at LoT visit, compared to others (DYS: 97,8% vs 66,7%, p<0,001; AH: 86,9% vs 65,2%, p=0,031). For what concerns the retention rate, patients who developed DYS or AH during bDMARD treatment continued the drug for a longer period of time (DYS 95,5 vs 19,6 months, p<0,001; AH 72,1 vs 23,4 months, p<0,001). In particular, patients with AH who concomitantly carried out therapy with ACE-inhibitors (ACEi) and/or angiotensin II receptor blockers (ARB) continued bDMARDs for nearly 20 more months than patients who were not exposed to these drugs (40,5 vs 23,4 months, p=0,001) and more frequently maintained the bDMARDS at LoT (59,42% vs. 47,53%). In case of withdrawal in the ACEi/ARB exposed cohort, this was due to well-being and disease remission rather than inefficacy or adverse reaction (p=0,025). In dyslipidemic patients treated with statins, data showed that bDMARDs were continued for a longer time than in DYS patients treated with other anti dyslipidemic therapies (41,09 vs. 26,50 months, p=0,042).

Conclusion:

our data suggest that AH and DYS may be associated with higher frequency of adverse events but a better drug retention. The combination of bDMARD and ACEi/ARB may determine a better control of the inflammatory process by inhibition of angiotensin II, favouring the achievement of remission. In AH patients on bDMARDs, ACEi and ARB could therefore represent an useful anti-hypertensive drug choice. Similarly, statins could be the treatment of choice in DYS patients.
