Background: The objective of the study was to assess clinical and imaging features of rheumatoid arthritis (RA) associated with interstitial lung disease (ILD), (RA-ILD) group, in comparison to RA without ILD (RA-C) and to identify the associated factors to ILD.Methods: This was a retrospective comparative study (June 2015 to March 2022) including RA patients aged ≥18 years. The RA-C control group was matched according to age (±2 years), gender, and RA duration (±2 years). General data, RA characteristics, ILD features, and treatment modalities were recorded. Statistical analysis was performed to determine the predictive factors of ILD.Results: A total of 104 patients were included (52 RA-ILD and 52 RA-C); sex ratio was 0.36. Mean age was 66.3±11 years (RA-ILD) versus 65.6±10.8 years (RA-C) (p=0.72). In comparison to RA-C, RA-ILD patients were significantly higher smokers (p=0.01) and physically inactive (p=0.01). Regarding RA features, RA-ILD patients have significantly increased positive anti-citrullinated peptide antibody (ACPA) (p=0.01), ACPA rate (p<0.001), erosive disease (p<0.001), and disease activity score (p<0.001). Mean time to ILD diagnosis was 5.85±7.16 years. Chest high-resolution computed tomography (HRCT) patterns of disease were identified: nonspecific interstitial pneumonia (NSIP) (28.8%), usual interstitial pneumonia (UIP) (17.3%), organizing pneumonia (OP) (25%), acute interstitial pneumonia (13.5%), and respiratory bronchiolitis (3.8%). Multivariate analysis identified smoking, high baseline DAS28 (disease activity score 28) and ACPA positivity as predictive factors of ILD.Conclusion: Our results confirmed the reported associated factors of ILD in RA (smoking, higher disease activity, ACPA positivity). Thus, we need to target the modifiable factors by supporting and educating RA patients to quit smoking and intensify disease modifying anti-rheumatoid drugs (DMARD) to reach remission.

Introduction: Spondyloarthritis (SpA) is a common rheumatic inflammatory disease and can impact patients’ work productivity. We aimed to evaluate the impact of pain catastrophizing and central sensitization on work outcomes in young SpA patients and determine the predictive factors of work productivity loss.Material and methods: We performed a cross-sectional study over 6 months. We included patients aged between 18 and 50 years old, diagnosed with axial or peripheral SpA. Pain catastrophizing and central sensitization were assessed using the Pain Catastrophizing Scale (PCS) and Central Sensitization Inventory (CSI) questionnaire, respectively. Impact of SpA on work productivity and activity impairment during and out-side of work was measured with the Work Productivity and Activity Impairment Questionnaire (WPAI: Spondyloarthritis).Results: A total of 72 patients were enrolled, with a median age of 39 years (28.3–46), 65.3% men, and 54.4% working patients. Median scores of activity impairment outside of work, and work productivity loss were 50% (40–70), and 50% (40–60), respectively. Median absenteeism and presenteeism scores were 0% (IQR 0–7), and 100% (IQR 86.5–100), respectively. Regarding work-related outcomes: activity impairment was positively correlated with CSI and PCS; presenteeism was significantly associated with male sex (p = 0.009); and work productivity loss was positively associated with anxiety, depression, and poor quality of life. Multivariate regression analysis identified predictive factors of work productivity loss: male sex, poor quality of life, and prolonged morning stiffness.Conclusions: Assessment of the impact of pain catastrophizing and central sensitization on work-related outcomes in patients with SpA is important to understand the burden of illness and to identify early those in need of interventions in clinical practice.

Background: Calcium-pyrophosphate-dihydrate-disease (CPPD) is a crystal-induced arthropathy. The lumbar-spinal involvement is rare and often under-diagnosed. This study aimed to report the case of a lumbar spine CPPD involvement and to perform a systematic review of clinical, imaging features of lumbar involvement in CPPD patients, and treatments that have been implemented. Methods: This systematic review was conducted in accordance with the Preferred-Reporting-Items-for-Systematic-Reviews and Meta-Analyses (PRISMA) guidelines. Results: One hundred and sixty-seven articles met the search criteria using electronic databases searches. We retained 28 articles (20 case reports, 2 case series, 1 family survey, 4 retrospective studies, and 1 prospective study) involving a total of 62 patients. The age ranged between 39 and 89 years old. Among patients with lumbar spine CPPD, 32 were women. The duration of symptoms varied between one day and 8 years. The affection has been discovered during back pain in most cases. In 5 studies, the diagnosis was made on histological specimens of patients operated on for another pathology. X-ray showed calcifications in 2 cases. CT-scan detected calcium deposit in 7 cases. MRI showed lesions going from the increased signal of the disk, to calcified or not-cystic lesion of the facet joints, an intramedullary mass mimicking a schwannoma. Histological examination established the diagnosis of CPPD in 21 patients in all studies. Medical treatment included NSAIDs, Colchicine, Interleukin-1-receptor-antagonist, and antibiotics. Surgery was performed on 13 patients and allowed to establish the histological diagnosis. Conclusion: In the case of inflammatory back pain in elderly subjects, without an infectious gateway, diagnosis of CPPD should be considered, especially for patients with a history of spinal surgery or degenerative radiography changes. CT scan is more sensitive than conventional radiographs. The discovertebral biopsy is the Gold-Standard and should be performed whenever the diagnosis was uncertain. Treatment includes the medical and surgical components.

Background: This study aimed to assess the benefits of associating rehabilitation with therapeutic patient education (TPE) to decrease fear-avoidance belief and pain and improve function in adults with chronic low back pain (CLBP).Methods: This randomized controlled study included 100 patients with CLBP according to the CONSORT (Consolidated Standards of Reporting Trials) guidelines. The patients were divided into two teams: group A that participated in the TPE in association with rehabilitation and group B that received rehabilitation only. Pain and functional amelioration were assessed initially (T0) and at the end of the program (T1) using a visual analog scale at rest, work, and activity, and the Echelle d’Incapacité Fonctionnelle pour l’Évaluation des Lombalgies scale. Psychological and apprehension and avoidance assessments were also conducted, including the evaluation of depression, anxiety, fear-avoidance belief, and kinesiophobia using the Hospital Anxiety and Depression Scale, Fear-Avoidance Beliefs Questionnaire, and Tampa scale of kinesiophobia scale.Results: The evaluation of progression initially (T0) and then at the end of the program (T1) revealed a significant reduction in pain at rest (P=0.00) and while working (P=0.00) and doing physical activity (P=0.03); a decrease in anxiety (P=0.03), fear-avoidance belief (P=0.03), and kinesiophobia (P=0.02); and an improvement in function (P=0.00) for patients in group A without amelioration of depression (P=0.15). Concerning group B, we identified a significant regression in pain at rest (P=0.001) and while working (P=0.03) and doing physical activity (P=0.00); depression (P=0.01); fear-avoidance beliefs (P=0.00); and kinesiophobia (P=0.002). Comparison between the groups revealed that associating TPE with rehabilitation resulted in a more significant improvement in function (P=0.00), anxiety (P=0.00), fear-avoidance belief (P=0.00), and kinesiophobia (P=0.00).Conclusion: Associating TPE with rehabilitation improved function and reduced fear, false beliefs, and kinesiophobia of movement in patients with CLBP.

Background The aim of our study was to assess subclinical atherosclerosis in spondyloarthritis (SpA) by combining three ultrasound methods (flow-mediated dilation (FMD), carotid intima–media thickness (cIMT) and Ankle Brachial Index (ABI)) and to determine the predictive factors of theses parameters. Methods This was a case control study conducted over 12 months including 47 patients with SpA-free-cardiovascular (CV) disease in comparison with age and sex matched 47 healthy controls. Sociodemographic, clinical and biological features as well as therapeutic modalities were recorded in our patients. All subjects had Doppler ultrasound with measurement of cIMT, FMD and ABI. Ultrasound measurements were compared between patients and controls. Linear regression was performed and assessed by machine learning to determine the predictive models of markers of subclinical atherosclerosis. Results We found higher cIMT (p<0.0001), lower FMD (p=0.008) and higher left ABI (0.048) in patients with SpA compared with controls. cIMT was positively correlated to patient-related parameters (age, systolic blood pressure) and disease parameters (age at onset of SpA, disease duration and renal involvement). Biologically, cIMT was positively correlated with creatinine, blood-glocose, total cholesterol (CT) and CT/cholesterol-high density lipoprotein ratio. FMD was negatively correlated with male gender, age, systolic blood pressure, creatinine, blood glucose and Left Lequesne Index. ABI was significantly associated with diastolic blood pressure. Multiple regression analysis identified age, CT and creatinine as independents predictive factors for increased cIMT. Regarding endothelial dysfunction, blood glucose and Left Lequesne Index were the independents predictive factors of decreased FMD. Conclusion Our study supported the accelerated subclinical atherosclerosis in patients with SpA. This subclinical atherosclerosis was mainly mediated by traditional CV risk factors.
