Objectives Undifferentiated connective tissue diseases (UCTDs) are systemic autoimmune conditions that cannot be diagnosed nor classified as defined CTD; the majority maintains an undifferentiated profile (stable UCTD, sUCTD) over time. Data on long-term outcomes of sUCTD are lacking.Methods Retrospective longitudinal analysis of an inception cohort of 141 patients with sUCTD.Disease evolution and damage accrual were evaluated at 1, 5 and 10 years. Partial least square (PLS) regression was used to identify the basal variables contributing to damage accrual at 1, 5 and 10 years of follow-up. Trend of damage over time was compared with a cohort of age-matched and sex-matched patients with systemic lupus erythematosus (SLE) by means of Nelson-Aalen analysis.Results 11.3% of patients evolved to a definite CTD after a median 11 years (IQR 6–25) from the first symptom. At last visit, 10% were on glucocorticoids and 6% on immunosuppressive therapy. In 27.3%, at least one item of organ damage was recorded according to the SLICC/DI score (mean score 1.19±0.46). At PLS analysis, age at diagnosis and age at first symptoms were related to damage at 1 year, not taking antimalarials and taking immunosuppressants were associated with damage at 5 years.The mean survival without damage was 9.3 years in sUCTD and 8.4 years in SLE. The 10-year probability without damage was 62% and 23% in SLE and sUCTD, respectively (p=0.015).Conclusions Although less significantly impacted than in patients with SLE, in the long-term UCTDs can accumulate organ damage and evolve into defined connective tissue diseases.

Objectives To investigate pregnancy outcomes in women with autoimmune rheumatic diseases (ARD) in the Italian prospective cohort study P-RHEUM.it.Methods Pregnant women with different ARD were enrolled for up to 20 gestational weeks in 29 Rheumatology Centres for 5 years (2018–2023). Maternal and infant information were collected in a web-based database.Results We analysed 866 pregnancies in 851 patients (systemic lupus erythematosus was the most represented disease, 19.6%). Maternal disease flares were observed in 135 (15.6%) pregnancies. 53 (6.1%) pregnancies were induced by assisted reproduction techniques, 61 (7%) ended in miscarriage and 11 (1.3%) underwent elective termination. Obstetrical complications occurred in 261 (30.1%) pregnancies, including 2.3% pre-eclampsia. Two cases of congenital heart block were observed out of 157 pregnancies (1.3%) with anti-Ro/SSA. Regarding treatments, 244 (28.2%) pregnancies were treated with glucocorticoids, 388 (44.8%) with hydroxychloroquine, 85 (9.8%) with conventional synthetic disease-modifying anti-rheumatic drugs and 122 (14.1%) with biological disease-modifying anti-rheumatic drugs. Live births were 794 (91.7%), mostly at term (84.9%); four perinatal deaths (0.5%) occurred. Among 790 newborns, 31 (3.9%) were small-for-gestational-age and 169 (21.4%) had perinatal complications. Exclusive maternal breast feeding was received by 404 (46.7%) neonates. The Edinburgh Postnatal Depression Scale was compiled by 414 women (52.4%); 89 (21.5%) scored positive for emotional distress.Conclusions Multiple factors including preconception counselling and treat-to-target with pregnancy-compatible medications may have contributed to mitigate disease-related risk factors, yielding limited disease flares, good pregnancy outcomes and frequency of complications which were similar to the Italian general obstetric population. Disease-specific issues need to be further addressed to plan preventative measures.

Objective The objective is to evaluate perscriptions of belimumab (BEL), how these have changed over the years and their impact on clinical outcomes in patients with systemic lupus erythematosus (SLE).Methods This is a retrospective analysis of prospectively collected data. We retrieved demographic and clinical data and concomitant therapies at BEL starting (baseline). Disease activity was assessed at baseline and after 6 and 12 months and organ damage at baseline and at the last visit.Results From 422 patients followed in the Pisa SLE cohort, 102 patients received BEL and were included and 22 (21.6%) were immunosuppressant (IS)-naïve. Lupus Low Disease Activity State (LLDAS) with a glucocorticoid (GC) dosage ≤5 mg/day (LLDAS5) and remission were achieved by 47% and 38% of patients at 6 months, and by 75% and 66% at 12 months. Comparing IS-naïve patients with those who received BEL after at least one conventional IS, we did not find significant differences in baseline characteristics and in the achievement of LLDAS5 and remission. Despite at baseline we did not observe significant differences in mean GC daily dosage, IS-naïve patients were taking a significantly lower GC daily dose at 6 and 12 months. Interestingly, IS-naïve patients were more common in the most recent years.Conclusions Our data confirm that BEL is effective in controlling disease activity, and in recent years BEL has been considered as an earlier treatment option before other IS. Early introduction of BEL can be at least as effective as a step-up approach and can help to reduce the GC dosage.

Background Some myopathies can lead to dropped head or bent spine syndrome (DH/BS). The significance of this symptom has not been studied in inflammatory myopathies (IM).Objectives To assess the significance of DH/BS in patients with IM.Methods Practitioners from five IM networks were invited to report patients with IM suffering from DH/BS (without other known cause than IM). IM patients without DH/BS, randomly selected in each participating centre, were included as controls at a ratio of 2 to 1.Results 49 DH/BS-IM patients (DH: 57.1%, BS: 42.9%) were compared with 98 control-IM patients. DH/BS-IM patients were older (65 years vs 53 years, p

Objective The aim of this work is to explore patient’ unmet needs of rare and complex rheumatic tissue diseases (rCTDs) patients during pregnancy and its planning by means of the narrative-based medicine (NBM) approach.Methods A panel of nine rCTDs patients’ representatives was identified to codesign a survey aimed at collecting the stories of rCTD patients who had one or more pregnancies/miscarriages. The results of the survey and the stories collected were analysed and discussed with a panel of patients’ representatives to identify unmet needs, challenges and possible strategies to improve the care of rCTD patients.Results 129 replies were collected, and 112 stories were analysed. Several unmet needs in the management of pregnancy in rCTDs were identified, such as fragmentation of care among different centres, lack of education and awareness on rCTD pregnancies among midwifes, obstetricians and gynaecologists. The lack of receiving appropriate information and education on rCTDs pregnancy was also highlighted by patients and their families. The need for a holistic approach and the availability specialised pregnancy clinics with a multidisciplinary organisation as well as the provision of psychological support during all the phases around pregnancy was considered also a priority.Conclusion The adoption of the NBM approach enabled a direct identification of unmet needs, and a list of possible actions was elaborated to improve the care of rCTD patients and their families in future initiatives.

Objective A subanalysis of the multicentre Early Lupus inception cohort was performed to investigate the real-world Glucocorticoids (GCs) Use in newly diagnosed systemic lupus erythematosus (SLE) Patients (GULP).Methods Patients starting prednisone (PDN) ≥5 mg/day and concomitant hydroxychloroquine or immunosuppressant within 12 months of SLE classification were enrolled. Core set variables were recorded at baseline and every 6 months, including changes in PDN dose, European Consensus Lupus Activity Measurement (ECLAM) and Systemic Lupus International Collaborating Clinics damage index. Regression models analysed predictors of tapering PDN

Introduction The European Reference Network (ERN) ReCONNET is the ERN aimed at improving the management of rare and complex connective tissue and musculoskeletal diseases (rCTDs) across the European Union (EU). In the mission of ERN ReCONNET, clinical practice guidelines (CPGs) play a crucial role, representing a valid tool towards the harmonisation of the management of rCTDs while improving effectiveness and quality of care delivered to patients.Methods ERN ReCONNET developed two surveys to map the adherence to rCTDs CPGs among healthcare providers and to assess the knowledge and awareness of CPGs for their diseases among patients, family members and caregivers.Results The results of the surveys highlighted that healthcare professionals find it useful to apply CPGs in clinical practice (93%), while 62% of them experience difficulties and barriers in the application in their centres. Healthcare professionals also highlighted the need to develop CPGs for all rCTDs and to implement the use of the existing CPGs in clinical practice. On the other hand, patients, families and caregivers are relatively aware of the purpose of CPGs (51%) and 62% of them were aware of the existence of CPGs for their disease. Patient-friendly versions of CPGs and patients’ lifestyle guidelines should be systematically developed contributing to the empowerment of patients in the disease management.Conclusion ERN ReCONNET is addressing the main issues identified in the results of the survey, promoting practical actions for the local adaptation of CPGs across Europe, improving their routine clinical use and increasing the awareness on CPGs among rCTDs patients, family members and caregivers.

Background Fatigue is a very common and debilitating symptom in patients with systemic lupus erythematosus (SLE), even among those with a mild or inactive disease. The objective of this study is to define fatigue determinants and describe the impact of fatigue on health-related quality of life (HRQoL) and illness perception in a monocentric cohort of patients with SLE.Methods This is a cross-sectional study. Adult patients with SLE were included. For each patient, demographics, medications, comorbidities, organ damage (Systemic Lupus International Collaborating Clinics Damage Index), active disease manifestations and Systemic Lupus Disease Activity Index scores were collected. It was evaluated if each patient met the definitions of remission and low disease activity. At enrolment, each patient completed the Short Form-36 (SF-36), Functional Assessment Chronic Illness Therapy-Fatigue (FACIT-F), Lupus Impact Tracker (LIT), Systemic Lupus Activity Questionnaire (SLAQ) and Brief Index of Lupus Damage (BILD). The FACIT-F questionnaire was also administered to a group of healthy controls.Results 223 patients were included (mean age 44.9±13.2 years, median disease duration 13 years). 18.2% had an active disease, 43.5% met the definition of remission on treatment, and 11.8% had a concomitant fibromyalgia. The median FACIT-F score of our cohort was significantly lower compared with that of healthy controls (40 vs 47; p
