Background/objectives Factors associated with chronic heart failure (CHF) in patients with systemic lupus erythematosus (SLE) have received little attention. Recent data on the use of hydroxychloroquine in the treatment of SARS-CoV-2 infection have cast doubt on its cardiac safety. The factors associated with CHF, including therapy with antimalarials, were analyzed in a large multicenter SLE cohort. Methods Cross-sectional study including all patients with SLE (ACR-1997 criteria) included in the Spanish Society of Rheumatology Lupus Register (RELESSER), based on historically gathered data. Patients with CHF prior to diagnosis of SLE were excluded. A multivariable analysis exploring factors associated with CHF was conducted. Results The study population comprised 117 patients with SLE (ACR-97 criteria) and CHF and 3,506 SLE controls. Ninety percent were women. Patients with CHF were older and presented greater SLE severity, organ damage, and mortality than those without CHF. The multivariable model revealed the factors associated with CHF to be ischemic heart disease (7.96 [4.01-15.48], p<0.0001), cardiac arrhythmia (7.38 [4.00-13.42], p<0.0001), pulmonary hypertension (3.71 [1.84-7.25], p<0.0002), valvulopathy (6.33 [3.41-11.62], p<0.0001), non-cardiovascular damage (1.29 [1.16-1.44], p<0.000) and calcium/vitamin D treatment (5.29 [2.07-16.86], p=0.0015). Female sex (0.46 [0.25-0.88], p=0.0147) and antimalarials (0.28 [0.17-0.45], p<0.000) proved to be protective factors. Conclusions Patients with SLE and CHF experience more severe SLE. Treatment with antimalarials appears to confer a cardioprotective effect.

Background:Inflammatory bowel disease (IBD) is an extra-articular manifestation that can appear in spondyloarthritis (SpA), as well as uveitis and psoriasis. Its prevalence is 5-10%, although subclinical intestinal inflammation has been found in up to 60%. Biological therapy (BT) can be the treatment for IBD or produce it paradoxically. Fecal calprotectin (FC) is an intestinal inflammation marker, useful for early diagnosis and monitoring disease activity.Objectives:To describe the frequency and characteristics of IBD in SpA with BT.Methods:Descriptive and retrospective study (January 2003-January 2019) of patients with SpA that develop IBD in a single center. Epidemiological variables, type of SpA, presence of IBD and its characteristics, levels of FC, presence of BT at IBD onset and treatment received were registered.For the analysis, frequencies and percentages were used in qualitative variables and mean±standard deviation (SD) in quantitative. Statistical analysis was performed with IBM SPSS v.23.Results:We studied 270 patients with SpA, 70.4% male with a mean age of 39.9±12 years. The subtypes of SpA were: ankylosing spondylitis (AS) (n=133; 49.3%), psoriatic arthritis (PsA) (n=116; 43%), undifferentiated SpA (n=16; 5.9%), SpA non-Rx axial (n=3; 1.1%) and reactive arthritis (n=2; 0.7%).IBD was observed in 25 patients (9.26%), 80% male. At the time of IBD onset, they had a mean age of 39.12±9.8 years, the mean ESR was 31.15±24mm1ªh, CRP 2.7±2mg/dL and BASDAI 4.6. 16 patients had AS, 6 PsA and 3 undifferentiated SpA. TABLE 1.Regarding Spa diagnosis, IBD appeared after in 15 patients with an average time of development of 8.39±8 years, before in 7 and was simultaneous in 3. The subtypes of IBD were: Crohn’s disease (CD) in 13 patients, ulcerative colitis (UC) in 9 and indeterminate colitis (IC) in 3. The FC was > 200μg/g in 17 patients (68%), normal (<50μg/g) in 1 and between 50-200μg/g in 7. The incidence rate adjusted for follow-up of the 25 cases was 7.7 cases/1000 patients-year.At the time of the IBD onset, 6 patients were with BT: Etanercept (ETN) (n=2), Infliximab (IFX) (n=1), Adalimumab (ADA) (n=1), Secukinumab (SCK) (n=1) and Ustekinumab (UST) (n=1). The BT had been initiated the previous 12 months in 5 of them. The incidence rate adjusted for follow-up of the 6 cases of IBD after BT was 1.83 cases/1000 patient-years. TABLE 2.The treatment of the 25 patients with IBD was mesalazine (n=15), oral corticoid (n=5), methotrexate (n=7) and BT in all cases. The BT was: ADA (n=11; 44%), IFX (n=6; 24%), UST (n=3; 12%), golimumab (n=3; 12%), SCK (n=1; 4%) and vedolizumab (n=1; 4%). The indication was intestinal in 4 patients, joint in 8 and both in 13.The clinical and analytical evolution in all patients was satisfactory, with a mean ESR of 11.6±9mm1ªh, CRP 0.6±0.3mg/dL and BASDAI 2 in the last control, after an average time of evolution of 12.5±9.3 years.Conclusion:In this series, IBD was observed in 9.26% of patients with SpA of which 64% were AS. The most frequent form was CD and it was diagnosed after SpA in 6...

BackgroundUveitis is the most frequent extra-articular manifestation (EAM) of spondyloarthritis (SpA). Its prevalence is approximately 30% and increases with the duration of the SpA. The characteristic pattern is anterior, acute, recurrent and unilateral uveitis. However, the frequency and characteristics of uveitis in SpA treated with biological therapy (BT) are unknown.ObjectivesThe main target is to describe the frequency and characteristics of uveitis in SpA with BT in a single centre.MethodsDescriptive and retrospective study (January 2003-December 2017) of SpA that develops uveitis in a reference hospital. The epidemiological variables, type of SpA, presence of uveitis and its characteristics, presence of BT at the time of onset and treatment received are collected. For the analysis, frequencies and percentages were used in qualitative variables, and mean and standard deviation (SD) for quantitative variables. Statistical analysis was performed with IBM SPSS v.23.ResultsWe studied 246 patients with SpA. The subtypes of SpA were: ankylosing spondylitis (AS) (n=125, 50.8%), psoriatic arthritis (PsA) (n=101, 41.1%), undifferentiated SpA (n=13, 5.3%), non-radiographic axial Spa (n=3, 1.2%), enteropathic arthropathy (n=3, 1.2%) and reactive arthritis (n=1, 0.4%).Uveitis was observed in 41 patients (16.7%) after an average time of development of 109.47 (73.9) months of the SpA. The incidence rate was 5.5 cases of uveitis/100 patients-year of follow-up. 70.7% were men and the mean age(SD) was 47.4 (12.06) years. 87.8% of the cases were HLAB27 positive and had a family history of SpA 41.5%.Uveitis was observed in 33 patients (80.5%) with AS, in 6 (14.6%) with PsA, in 1 (2.4%) with non-Rx axial SpA and in 1 (2.4%) with undifferentiated SpA. (table 1)The uveitis pattern was anterior (100%), acute (92.7%), unilateral (87.8%) and in 12.2% bilateral (80% in PsA). At the time of onset of uveitis, the mean ESR was 30.11 mm1ªh, CRP 3.56 mg/dL, DAS28 3.66 and BASDAI 3.21.Regarding the diagnosis of SpA, uveitis was after (85.4%), before (12.2%) and simultaneous (2.4%).At the time of the onset of uveitis, 14 patients (34.1%) were with BT (35.7% etanercept, 28.6% infliximab, 21.4% adalimumab, 7.1% golimumab and 7.1% certolizumab). BT was modified in 3 of the cases.The treatment of uveitis was topical (78%), corticoids in oral regimen (57.5%), conventional DMARDs (12.5%), with methotrexate predominating in 60% of cases and BT (15%). The most used biologics were adalimumab (50%), infliximab (33.3%) and sekukinumab (16.7%).Abstract THU0259 – Table 1Characteristics of the UVEITIS in SpA subtypesConclusionsIn our series, uveitis was observed in 16.7% of patients with SpA of which 80.5% were AS and 14.6% PsA. The most frequent uveitis was anterior, unilateral, acute and recurrent. In PsA, the association with HLA B27 was less frequent and was more bilateral. In most cases, the diagnosis was later than the SpA.Disclosure of InterestNone declared

Background:In our population the prevalence of hypovitaminosis D is high. A recent cross-sectional observational study conducted in Spain shows that 63% of postmenopausal women who receive osteoporosis (OP) therapy and 76% who do not receive treatment had 25 (OH) D levels below 30 ng / mL1.The latest studies show a relationship between hypovitaminosis D and the development of systemic inflammatory and tumor diseases, determined by the presence of receptors in various tissues, including breast.Objectives:To determine which levels of serum 25 (OH) D, and secondarily calcium, phosphorus, PTH and CTX, present 200 patients diagnosed with breast cancer and taking hormonal treatment, referred to a monographic OP consultation of a tertiary hospital for the assessment of their bone metabolism, and if these values differ from what is expected for the general population.Methods:Retrospective cross-sectional study of 200 women diagnosed with breast cancer receiving treatment with aromatase inhibitors (AI), performed in a tertiary hospital. Blood levels of vitamin D, calcium, phosphorus, PTH and CTX have been collected, as well as other variables and risk factors.Results:200 patients with a mean age of 64.8 years and an ED of 9.5 were collected. The median is 64.5 (Q1 58 and Q3 72).The vitamin D levels presented by the study patients were <10 ng/mL in 13 patients (6.67%), 11-20 ng/mL in 50 (25.64%), 21-30 ng/mL in 68 (34.87%), 31-70 ng/mL in 62 (31.79%), and> 70 ng/mL in 2 (1.03%). This implies that in 67.18% of the patients they had values below the optimal range.92.31% of patients (180) presented PTH values within the normal range and only 7.69% presented values above normal.The serum calcium and phosphorus levels of the patients selected for the study had ranges within normal (99.49%) except 1 case that presented high values (0.51%) for both.The values of CTX (carboxyterminal telopeptide used as a marker of bone resorption) were in the normal range in 81.96% of patients (159), low values in 0.52% (1) and values above the normal range by 17.53% (34).Conclusion:The prevalence of insufficient levels of vitamin D in our study (Breast cancer + AI) is not greater than that estimated for the general population according to various studies.Our study found that 67.18% of patients (2/3 of the selected population) had values below those considered optimal (<30 ng / mL) and 32% had values <20.Only 7.69% of the patients presented PTH values above the normal range.In 82% of patients, CTX used as a marker of bone resorption had normal values.References:[1]Quesada Gomez JM, Díaz Curiel M, Sosa Henríquez M, Malouf-Sierra J, Nogués-Solan X, Gómez-Alonso C, et al.
