Background: Disease and treatment pattern of patients (pts.) differ between clinical trials and observational cohorts. We initiated a large regional, prospective observational cohort of pts. with inflammatory rheumatic musculoskeletal diseases (iRMD) in order to set up a database to facilitate several investigations on epidemiology, diagnosis, and prognosis in the field of rheumatology.

Objectives: The purpose of this study was to describe patients and disease characteristics in pts. with iRMD and to analyse prevalence and type of various comorbidities.

Methods: Adult pts with a clinical diagnosis of iRMD were included in the LORE cohort, an ongoing prospective longitudinal observational cohort with follow-up visits according to a fixed protocol. The only inclusion criteria was a documented clinical diagnosis of iRMD according to their rheumatologist, e.g. rheumatoid arthritis (RA), psoriatic arthritis (PsA), axial spondyloarthritis (axSpA)), connective tissue diseases, vasculitis or other iRMDs (e.g. Behcet disease). We collected the following variables: sociodemographic data, clinical data, patient-reported outcome, and treatment. Descriptive analysis was performed and factors that may be predictive of patient global assessment were investigated using uni- and multivariable regression analyses.

Results: A total of 3551 pts. (female 61.4%, mean age: 55.4 (15.6) years, 935 ≥65 years of age (26.3%)) were recruited. The most common diagnoses were RA (1618 (45.6%), axSpA (672 (18.9%) and PsA (491 (13.8%), followed by connective tissue diseases (351 (9.9%) and vasculitis (199 (5.6%). One third of pts had a symptom duration ≥10 years, moderate to severe depressive symptoms, moderate disease activity and impairments in health-related quality of life (Table 1). Patient global were lowest in vasculitis (34.8 (24.3) and highest in RA (43.3 (24.5)). Prednisolone dosage was highest in pts with vasculitis (8.3 (14.1)) and lowest in axSpA pts (5.1 (4.4)). Most pts with RA used csDMARDs (1119 (70.1%) compared to pts with axSpA (103 (15.9%). Proportion of pts. with bDMARDs ranged between axSpA (380 (56.5%) and myositis (2 (7.4%), whereas tsDMARDs use were highest in Behçet’s disease (3 (13.6%) and RA (101 (6.2%)). 2998 (84.4%)had at least one comorbidity. The prevalence of comorbidities were highest in the PMR population (79 (98,8%) and lowest in the axSpA group (493 (73,4%). Among all comorbidities, cardiovascular (1512 (42.6%) and musculoskeletal (1900 (53.5%) comorbidities were the most prevalent one. Results from multivariable regression analysis showed that higher CRP levels, longer symptom duration and higher number of comorbidities were associated with higher values of patient global, while male sex and use of bDMARDs were associated with lower values of patient global (Table 2).

Conclusion: This large regional observational cohort showed differences in treatment pattern between various types of iRMDs. Our findings illustrate the potential impact of comorbidities on patients well-being and indicate that a more holistic management approach is needed. This large cohort should facilitate the conduct of researches in different areas in order to improve our knowledge on impact of disease of pts with iRMD.
