Disease activity outcome measures are only available in half of the electronic medical files of patients with axial spondyloarthritis followed in an outpatient clinic: the results of an audit of a tertiary-care rheumatology department.

Current recommendations for management of patients with axial spondyloarthritis (axSpA) include regular collection of validated disease activity outcomes. This study aimed at evaluating the proportion of patients for whom validated outcome measures were available on their electronic medical reports (EMR), and the factors associated with the presence of such information on the EMR. We performed a cross-sectional monocentric observational study, including patients with an axSpA diagnosis who attended an outpatient visit between February, 2018 and February, 2019. Patients (demographics, disease characteristics, treatment) and physician characteristics (age, gender) and the disease activity outcome measures (BASDAI, CRP and ASDAS, and the items allowing to calculate them) were retrieved from the EMR. The proportion of patients in which disease activity outcome measures were available in the EMR was calculated, and the association between the presence of such outcomes and patients and physician's characteristics was evaluated. 320 EMR of axSpA patients seen in the outpatient clinic were examined. Among them, 131 (41%) and 123 (38.4%) had a BASDAI + CRP and an ASDAS reported, respectively, but at least one was available in 178 (55.6%) of the EMR. The most frequently reported disease activity items were duration of morning stiffness (n = 230, 72%) and CRP (n = 224, 70%). Only previous participation on a systematic holistic review was independently associated with a reported disease activity outcome. Thus, implementation of recommendations with regard to regularly collecting disease activity outcome measures is not optimal. The participation in educational programs including self-assessment educational programs might be a key to improve such implementation.

Evaluation of the impact of a nurse-led program of systematic screening of comorbidities in patients with axial spondyloarthritis: The results of the COMEDSPA prospective, controlled, one year randomized trial.

OBJECTIVE: To evaluate the impact of a nurse-led program of systematic screening for the management (detection/prevention) of comorbidities. METHODS: Prospective, randomized, controlled, open, 12-month trial (NCT02374749). PARTICIPANTS: consecutive patients with axial Spondyloarthritis (axSpA) (according to the rheumatologist) THE PROGRAM: A nurse collected data on comorbidities during a specific outpatient visit. In the event of non-agreement with recommendations, the patient was informed and a specific recommendation was given to the patient (orally and in a with a detailed written report). Patients were seen after one year in a nurse-led visit. TREATMENT ALLOCATION: random allocation (i.e. either this program or an educational program not presented here and considered here as the control group). MAIN OUTCOME: change after one year of a weighted comorbidity management score (0 to 100 where 0= optimal management). RESULTS: 502 patients were included (252 and 250 in the active and control groups, respectively): age: 47±12 years, male gender: 63%, disease duration: 14±11y. After one year, no differences were observed in a weighted comorbidity management score. However, the number of patients in agreement with recommendations was significantly higher in the active group for vaccinations (flu vaccination: 28.6% vs. 9.9%, p<0.01; pneumococcal vaccination:40.0% vs. 21.1%,p=0.04), for cancer screening (skin cancer screening: 36.3% vs. 17.2%, p=0.04) and for osteoporosis (bone densitometry performed: 22.6% vs. 8.7%, p<0.01; Vitamin D supplementation initiation: 51.9% vs. 9.4%, p<0.01). CONCLUSIONS AND RELEVANCE: This study suggests the short-term benefit of a single-visit nurse-led program for systematic screening of comorbidities for its management in agreement with recommendations, even in this young population of patients with axSpA.

Vitamin D status in spondyloarthritis: results of the ASAS-COMOSPA international study.

OBJECTIVES: Spondyloarthritis (SpA) encompasses both bone production and bone loss, and the latter is particularly linked to inflammation. Vitamin D deficiency has been associated with several inflammatory conditions (i.e. cardiovascular disease, rheumatoid arthritis), but it has been poorly evaluated in SpA patients. We aimed to a) describe the prevalence of vitamin D deficiency in SpA patients worldwide; b) compare SpA patients with and without vitamin D deficiency in terms of disease phenotype, activity severity and comorbidities. METHODS: This is an ancillary study of the ASAS-COMOSPA study initiative, an international cross-sectional study of patients with SpA. Demographics, patients' phenotype, disease activity/severity measures and comorbidities were assessed. Serum 25-hydroxyvitamin D (25OHD) deficiency was defined as <20 ng/mL (<50 nmol/L). STATISTICAL ANALYSIS: a) prevalence of vitamin D deficiency; b) comparison of the disease presentation/activity/severity and comorbidities in the group of patients with and without vitamin D deficiency by bi-variable and multivariable analysis. RESULTS: Vitamin D deficiency was observed in 527(51.2%) of the 1030 patients with available data who were not receiving any supplementation. Vitamin D deficiency was independently associated with the presence of radiographic sacroiliitis (OR=2.1 [95%CI1.3; 3.3]) and a 25OHD measured in winter and spring (OR=1.88 [95%CI 1.2; 2.9]). No independent association between vitamin D deficiency and comorbidities was found. CONCLUSIONS: This study suggests that vitamin D deficiency is common in SpA worldwide and is associated with season but also with more severe forms of SpA.

Vitamin D, disease activity and comorbidities in early spondyloarthritis.

OBJECTIVES: To assess the vitamin D status in patients presenting inflammatory back pain suggestive of axial spondyloarthritis and to assess the relationship between vitamin D status and disease activity/severity; comorbidities at baseline and during the first two years of follow-up. METHODS: DESIR is a prospective, multicentre, observational study. Vitamin D deficiency was defined as <50 nmol/L and severe deficiency less than 25 nmol/L. Clinical variables were collected at each six month interval visits during the two-year follow-up. RESULTS: A total of 700 patients were analysed. The mean vitamin D was 54.2±28.7 nmol/L. Severe deficiency were observed in 11.7% versus 5% in the DESIR cohort versus the French population respectively. In the DESIR cohort, after adjusting for season and ethnicity, vitamin D deficiency remained significantly associated with presence of radiological sacroiliitis, higher ASDAS score and elevated BASDAI. Such association was also found between vitamin D deficiency and the mean value of disease activity/severity parameters during the two-year follow-up. Otherwise, vitamin D deficiency was significantly associated with the presence of baseline abdominal obesity (OR=1.65 [1.05-2.61], p=0.03), low HDL (OR=1.71 [1.14-2.55], p=0.01) and presence of metabolic syndrome (OR=2.20 [1.04-4.64], p=0.03) at baseline. CONCLUSIONS: We found a higher percentage of patients with severe vitamin D deficiency in early axial spondyloarthritis. Vitamin D deficiency was associated with higher disease activity and severity and presence of metabolic syndrome. Further longitudinal studies are required to evaluate the interest of vitamin D supplementation on the long-term outcome of the disease.

Efficacy of anakinra for refractory acute calcium pyrophosphate crystal arthritis.

Acute synovitis induced by deposition of calcium pyrophosphate (CPP) and monosodium urate crystals involves interleukin-1ß production and activation. The efficacy of blocking interleukin-1ß activity (with an interleukin-1 receptor antagonist [anakinra] or interleukin-1ß antibody) is well documented for gout attacks but has only been reported in two single-case reports of CPP crystal-induced acute arthritis. Here we report on five cases (four males, mean age 71±27) of CPP crystal-induced inflammatory arthritis refractory and/or intolerant to usual drug therapy and efficiently treated with anakinra. Diagnosis of CPP crystal-induced arthritis was confirmed by identification of crystals in synovial fluid. CPP crystal-induced oligo-arthritis (n=4) and polyarthritis (n=1) were refractory to conventional treatments, including non-steroidal anti-inflammatory drugs, colchicine and steroids (systemic administration or intra-articular injection). After latent infection was ruled out, anakinra, 100mg/day, was administered subcutaneously for 3 days. Four patients showed rapid clinical and biological responses at a mean of 3 days after treatment. Anakinra provided good joint pain relief (baseline 0-100mm visual analog scale score 60±17mm, outcome 10±10mm) and decreased serum C-reactive protein level (58±43 to 5±2mg/L). Anakinra was well tolerated. One injection-site skin reaction was observed but no infection. Anakinra was effective and safe in this small series of patients with refractory arthritis due to acute CPP crystal deposition.
