The objective of this study was to evaluate glucocorticoid (GC) use in patients with polymyalgia rheumatica (PMR), giant cell arteritis (GCA) or both diseases (PMR + GCA) under rheumatological care. Data from patients with PMR (n = 1420), GCA (n = 177) or PMR + GCA (n = 261) from the National Database of the German Collaborative Arthritis Centers were analyzed regarding GCs and related comorbidities (osteoporosis, diabetes and cardiovascular disease), stratified by disease duration (DD). Longitudinal data were analyzed for all patients with a DD ≤ 2 years at database entry (n = 1397). Three-year data were available for 256 patients. Predictors of GC use ≥ 3 years were examined by logistic regression analyses. A total of 76% received GCs, and 19% (PMR) to 40% (GCA) received methotrexate. Median GC doses were 12.5 mg (PMR), 11.3 mg (GCA), and 20.0 mg/day (PMR + GCA) in a 0-6-month DD. Median GC doses ≤ 5 mg/day were reached at a 13-18-month DD in PMR patients and at a 19-24-month DD in GCA or PMR + GCA patients. In the multivariate analysis, baseline methotrexate (OR 2.03, [95% CI 1.27-3.24]), GCs > 10 mg/day (OR 1.65, [1.07-2.55]), higher disease activity (OR 1.12, [1.02-1.23]) (median 0.6 years DD), and female sex (OR 1.63 [1.09-2.43]) were predictive for GC therapy at ≥ 3 years. Of the examined comorbidities, only osteoporosis prevalence increased within 3 years. GC use for ≥ 3 years was reported in one-fourth of all the patients. A difficult-to-control disease activity within the first year was a good predictor of long-term GC need. [ABSTRACT FROM AUTHOR]

Objective To estimate the changes in direct and indirect costs induced by patients with rheumatoid arthritis (RA) in German rheumatology, between 2002 and 2011. To examine the impact of functional status on various cost domains. To compare the direct costs incurred by patients at working age (18-64 years) to patients at an age of retirement (≥65 years). Methods We analysed data from the National Database of the German Collaborative Arthritis Centres with about 3400 patients each year. Costs were calculated using fixed prices as well as annually updated cost factors. Indirect costs were calculated using the human capital as well as the friction cost approaches. Results There was a considerable increase in direct costs: from €4914 to €8206 in patients aged 18-64, and from €4100 to €6221 in those aged ≥65, attributable to increasing prescription of biologic agents (18-64 years from 5.6% to 31.2%, ≥65 years from 2.8% to 19.2%). This was accompanied by decreasing inpatient treatment expenses and indirect costs due to sick leave and work disability. The total growth of cost, on average, was €2437-2981 for patients at working age, and €2121 for patients at retirement age. Conclusions The increase in treatment costs for RA over the last decade was associated with lower hospitalisation rates, better functional status and a lower incidence of work disability, offsetting a large proportion of risen drug costs. Since the rise in drug costs has manifested a plateau from 2009 onwards, no relevant further increase in total costs for patients with RA treated in German rheumatology is expected.
