Purpose To model the American College of Rheumatology (ACR) outcomes, cost-effectiveness, and budget impact of certolizumab pegol (CZP) (with and without a hypothetical risk-sharing scheme at treatment initiation for biologic-naïve patients) versus the current mix of reimbursed biologics for treatment of moderate-to-severe rheumatoid arthritis (RA) in Finland. Methods A probabilistic model with 12-week cycles and a societal approach was developed for the years 2015–2019, accounting for differences in ACR responses (meta-analysis), mortality, and persistence. The risk-sharing scheme included a treatment switch and refund of the costs associated with CZP acquisition if patients failed to achieve ACR20 response at week 12. For the current treatment mix, ACR20 at week 24 determined treatment continuation. Quality-adjusted life years were derived on the basis of the Health Utilities Index. Results In the Finnish target population, CZP treatment with a risk-sharing scheme led to a estimated annual net expenditure decrease ranging from 1.7% in 2015 to 5.6% in 2019 compared with the current treatment mix. Per patient over the 5 years, CZP risk sharing was estimated to decrease the time without ACR response by 5%-units, decrease work absenteeism by 24 days, and increase the time with ACR20, ACR50, and ACR70 responses by 5%-, 6%-, and 1%-units, respectively, with a gain of 0.03 quality-adjusted life years. The modeled risk-sharing scheme showed reduced costs of €7866 per patient, with a more than 95% probability of cost-effectiveness when compared with the current treatment mix. Conclusion The present analysis estimated that CZP, with or without the risk-sharing scheme, is a cost-effective alternative treatment for RA patients in Finland. The surplus provided by the CZP risk-sharing scheme could fund treatment for 6% more Finnish RA patients. Funding UCB Pharma.

Biological therapy for ankylosing spondylitis (AS) has led to improved disease control beyond that of conventional treatments. International recommendations encourage clinicians prescribing biological treatments to register patients in national registers to collect information on outcome and toxicity. Patients with AS (n = 229) from the Register of Biological Treatment in Finland (ROB-FIN) with severe disease of long duration were followed-up for up to 24 months. Due to an active disease, one or more concomitant disease-modifying antirheumatic drugs (DMARDs) were used by 86% at commencement of biological therapy. This add-on strategy with infliximab led to a rapid pain relief and improvement of patient's and physician's global assessments, C-reactive protein/erythrocyte sedimentation rate, and swollen and tender joint counts within 6 weeks. Concomitant use of NSAID and oral corticosteroid was reduced. Corresponding results were documented at 3 months with etanercept, which was more recently approved for the treatment of spondyloarthropathies. Seventy-nine percent of the patients were ASAS 20 responders. A subgroup of AS patients with only axial involvement (n = 46) responded correspondingly. The first biological drug was discontinued in only 7% due to lack of efficacy and in 6% due to adverse events. Anti-TNF agents, often used in combination with DMARDs, appeared to have persistent effectiveness and limited toxicity in a real-life clinical setting in a cohort of Finnish AS patients with severe disease and long disease duration.

Rheumatic diseases do not usually cluster in time and space. It has been proposed that environmental exposures may initiate autoimmune responses. We describe a cluster of rheumatic diseases among a group of health center employees who began to complain of symptoms typically related to moldy houses, including mucocutaneous symptoms, nausea and fatigue, within a year of moving into a new building. Dampness was found in the insulation space of the concrete floor below ground level. Microbes indicating mold damage and actinobacteria were found in the flooring material and in the outer wall insulation. The case histories of the personnel involved were examined. All 34 subjects working at the health center had at least some rheumatic complaints. Two fell ill with a typical rheumatoid factor (RF)-positive rheumatoid arthritis (RA), and 10 had arthritis that did not conform to any definite arthritic syndrome (three met the classification criteria for RA). Prior to moving into the problem building one subject had suffered reactive arthritis, which had then recurred. Another employee had undiagnosed ankylosing spondylitis and later developed psoriatic arthritis, and another developed undifferentiated vasculitis. A total of 16 subjects developed joint pains, 11 of these after beginning work at the health center. Three subjects developed Raynaud's symptom. Fourteen cases had elevated levels of circulating immune complexes in 1998, 17 in 1999, but there were only three cases in 2001, when the health center had been closed for 18 months. The high incidence of joint problems among these employees suggests a common triggering factor for most of the cases. As some of the symptoms had tended to subside while the health center was closed, the underlying causes are probably related to the building itself and possibly to the abnormal microbial growth in its structures.
