- Background: Ankylosing spondylitis (AS) is characterized by pathologic new bone formation and bone loss. Vertebral fracture (VF) is a known complication of AS, whereas the risk of other major osteoporotic fractures (MOFs) is less studied.Objectives: To estimate incidence rates (IRs) of incident fractures (any, VF and other MOF (humerus, forearm and hip)) in patients with AS compared to controls from general population.Methods: This is a nationwide, register-based and observational cohort study including patients diagnosed with AS (n=11611, 65% men, mean age 48 years) identified in the National patient register (NPR) 2001 through 2015, and age- and sex-matched controls (n=58050) from the Swedish Population Register. The study period started 1 January 2007 or 3 months after the first AS diagnosis, whichever came later, and ended at the first occurrence of each fracture outcome (identified in the NPR), death, emigration or 31 December 2016. Patients and controls with any prior fracture in NPR within a 6-year period before start of the study period were not included. Any fracture (except skull and phalangeal fractures), VF and other MOF were identified in NPR according to pre-specified ICD codes. Each fracture outcome was analysed separately. Poisson regression was used to calculate IRs and incidence rate ratios (IRRs), overall and stratified by sex. Kaplan-Meier curves were plotted.Results: In total 807 (7.0%) of patients with AS and 3201 (5.5%) of matched controls had a history of prior fracture within a 6-year period, and were excluded from further analyses. We noted higher IRs for any fracture, VF and other MOF in AS vs controls, see Figure for Kaplan-Meier curves and Table for IRs and IRRs. In sex-stratified analyses, men with AS (vs. male controls) had a higher relative risk for all fracture outcomes, whereas among women with AS (vs. female controls), a higher relative risk was demonstrated for any fracture and VF. 5-year cumulative incidence for any fracture, VF and other MOF was 6.2%, 1.6% and 1.7%, respectively in AS and 4.3%, 0.3% and 1.2%, respectively in controls.

- Objectives To describe the incidence of atrioventricular (AV) block II-III, atrial fibrillation (AF), pacemaker implantation (PM) and aortic regurgitation in patients with ankylosing spondylitis (AS), undifferentiated spondyloarthritis (uSpA) and psoriatic arthritis (PsA) compared with the general population (GP) and with each other. Methods A prospective nationwide study with cohorts of patients with AS (n=6448), PsA (n=16 063) and uSpA (n=5190) and a GP (n=2 66 435) cohort, identified in 2001-2009 in the Swedish National Patient and Population registers. Follow-up began on 1 January 2006 and ended at event, death, emigration or 31 December 2012. Age-standardised and sex-standardised incidence rates and hazard ratios (HRs) were calculated. Results The highest incidence rates were noted for AF (5.5-7.4 events per 1000 person-years), followed by PM (1.0-2.0 events per 1000 person-years). HRs for AV block, AF, PM and aortic regurgitation were significantly increased in AS (HRs 2.3, 1.3, 2.1 and 1.9), uSpA (HRs 2.9, 1.3, 1.9 and 2.0) and PsA (HRs 1.5, 1.5, 1.6 and 1.8) compared with the GP cohort. The highest HRs were seen for AV block in male uSpA (HR 4.2) and AS (HR 2.5) compared with GP. Compared with PsA, significantly increased HRs were noted for PM (HR 1.5) in AS and for AV block (HR 1.8) in uSpA. Conclusions Patients with SpA are at increased risk of aortic regurgitation, cardiac rhythm disturbances and, as a probable consequence, also PM. Particularly for AF, the most common arrhythmia, increased caution is warranted, whereas AV block should be looked for especially in men with AS or uSpA.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To estimate absolute and relative risks for all-cause mortality and for severe COVID-19 in inflammatory joint diseases (IJDs) and with antirheumatic therapies.Methods: Through Swedish nationwide multiregister linkages, we selected all adult patients with rheumatoid arthritis (RA, n=53 455 in March 2020), other IJDs (here: spondyloarthropathies, psoriatic arthritis and juvenile idiopathic arthritis, n=57 112), their antirheumatic drug use, and individually matched population referents. We compared annual all-cause mortality March-September 2015 through 2020 within and across cohorts, and assessed absolute and relative risks for hospitalisation, admission to intensive care and death due to COVID-19 March-September 2020, using Cox regression.Results: During March-September 2020, the absolute all-cause mortality in RA and in other IJDs was higher than 2015-2019, but relative risks versus the general population (around 2 and 1.5) remained similar during 2020 compared with 2015-2019. Among patients with IJD, the risks of hospitalisation (0.5% vs 0.3% in their population referents), admission to intensive care (0.04% vs 0.03%) and death (0.10% vs 0.07%) due to COVID-19 were low. Antirheumatic drugs were not associated with increased risk of serious COVID-19 outcomes, although for certain drugs, precision was limited.Conclusions: Risks of severe COVID-19-related outcomes were increased among patients with IJDs, but risk increases were also seen for non-COVID-19 morbidity. Overall absolute and excess risks are low and the level of risk increases are largely proportionate to those in the general population, and explained by comorbidities. With possible exceptions, antirheumatic drugs do not have a major impact on these risks.

- Background: Patients with ankylosing spondylitis (AS) have an increased risk of spinal new bone formation characterized by the development of syndesmophytes. Knowledge of predictors for development of syndesmophytes is limited. Hepatocyte growth factor (HGF) has regulatory effects on a variety of cells in many different organs. HGF signaling can affect both osteoclast and osteoblast lineages and has been shown to promote osteogenesis. Cross-sectional association between increased HGF and increased modified Stoke Ankylosing Spine Score (mSASSS) has previously been shown [1], whereas knowledge of HGF as a predictor for new bone formation is lacking.Objectives: To study serum HGF as a predictor for development of new syndesmophytes in patients with AS followed for five years.Methods: Serum levels of HGF was analyzed using ELISA in patients with AS (modified NY-criteria) and in healthy controls (HC) at baseline. Spinal lateral radiographs were obtained at baseline and at the 5-year follow-up and assessed for development of new syndesmophytes using mSASSS. Univariate and multivariable logistic regression analyses were used to assess predictors for development of ≥ 1 new syndesmophyte.Results: Serum HGF and radiographs at baseline and follow-up were available for 163 patients, 88 men and 75 women, baseline mean age 50±12 years. AS patients had higher serum HGF than HC (n=80), p=0.050. In the AS group, 36 patients (22%) developed ≥ 1 syndesmophyte, 27 men and 9 women. In the total AS group, neither did baseline serum HGF differ between those who developed ≥ 1 new syndesmophyte and those who did not progress, nor did it predict development of ≥ 1 new syndesmophyte in the univariate analysis, p=0.25. Interestingly, men who developed ≥1 new syndesmophyte had higher serum HGF than the non-progressors (1706±454 vs 1420±338 pg/mL, p=0.001) and increased serum HGF at baseline predicted development of ≥ 1 syndesmophyte (OR per 1 SD HGF 2.39, 95% CI 1.31 to 4.36) in the univariate analysis. Serum HGF did not predict new syndesmophytes in women, p=0.13. Multivariable analysis for men including age, smoking, baseline syndesmophyte and serum HGF showed high HGF (OR per 1SD 1.90, 95% CI 1.01 to 3.59) and ≥1 baseline syndesmophyte (OR 3.48, 95% CI 1.09 to 11.07) to independently predict development of ≥ 1 new syndesmophyte. If baseline CRP was included in the multivariable model, serum HGF and baseline syndesmophytes remained the significant predictors.Conclusion: High baseline serum HGF was shown to independently predict the development of at least one new syndesmophyte over five years in men with AS.
