[Medical treatment of rheumatoid arthritis in 2014 : Current data from the German Collaborative Arthritis Centers]

Abstract (Expand)

BACKGROUND: Since the introduction of biologic treatment in rheumatoid arthritis (RA), disease activity and treatment modalities have changed substantially. The current provision and developments in … recent years are analyzed with annual data from the National Database of the Collaborative Arthritis Centers in Germany. METHODS: To analyze disease activity, diagnostics and treatment in RA patients in 2014 with regard to seropositivity and disease duration. Time trends from 2007-2014 are reported for disease activity (DAS28) distribution and biologic treatment. RESULTS: In 2014, a total of 8,084 RA patients were analyzed: 72 % were rheumatoid factor and/or ACPA positive, the mean age was 62 years and the mean disease duration 12 years. According to DAS28, 35.9 % were in remission, 19.2 % had low, 37.1 % moderate and 7.8 % high disease activity. An increase since 2007 was only observed in patients with a disease duration >2 years. Synthetic DMARDS were used for treatment in 78 %. Biologic treatment increased from 16 % (2007) to 27 % (2014). Especially those patients with a disease duration >5 years were treated more frequently with biologics. Seronegative patients had slightly less severe mean disease activity parameters. They were treated equally frequent with DMARDS but only half as often with biologics compared to seropositive patients. CONCLUSION: The use of biologics in RA patients has increased since 2007; however this was not observed in patients with short disease duration. Early intensive treatment adaption seems justified to improve disease activity in the large portion of patients who do not reach low disease activity under conventional DMARDs.

[How frequent are poor prognostic markers in rheumatoid arthritis? : An estimate based on three epidemiologic cohorts]

Abstract (Expand)

BACKGROUND: Unfavorable prognostic factors-high disease activity, early erosions, and autoantibodies-should be considered when making treatment decisions in rheumatoid arthritis (RA). There are little … data on the frequency of individual poor prognostic factors among RA patients in daily care. METHODS: Disease activity (Disease Activity Score, DAS28), erosions, antibodies against citrullinated peptides or rheumatoid factor (ACPA/RF+), previous treatment failure, inflammation markers, and functional disability (FFbH < 70) were defined as prognostic factors. Different treatment decision making situations were evaluated in disease-modifying antirheumatic drug (DMARD)-naive patients from the early RA CAPEA cohort (n = 1059), and in patients from the biologics register RABBIT after failure of one (n = 2217) or more (n = 3280) conventional synthetic (cs)DMARDs or one (n = 1134) or more (n = 795) biologic (b)DMARDs. With the national database of German arthritis centers (NDB), the frequency of these factors was analyzed according to treatment strata (no/1(st)/2(nd)/3(rd) DMARD; n = 5707). RESULTS: In DMARD-naive patients (CAPEA), 50% presented with DAS28 > 5.1, 64% were ACPA/RF+, 13% had erosions, and 37% functional disability (FFbH < 70). In RABBIT, 63 (1(st) csDMARD failure) to 81% (>/=2 bDMARD failures) were ACPA/RF+, 29 to 70% had erosions, 33 to 52% DAS28 > 5.1, and 41 to 66% had FFbH < 70, respectively. In the NDB, between 47 (DMARD-naive) and 82% (>/=2 previous DMARDs) were ACPA/RF+, 5 to 11%, had high disease activity under treatment (DAS28 > 5.1), and 26 to 50% had functional disability (FFbH < 70), respectively. CONCLUSION: With growing numbers of previous DMARD therapies, increasing proportions of patients have poor prognostic factors. This underlines the importance of these factors for a difficult-to-treat disease course.

Predictors of Reduced Health-Related Quality of Life in Adult Patients With Idiopathic Inflammatory Myopathies

Abstract (Expand)

OBJECTIVE: Extensive studies on health-related quality of life (HRQoL) in idiopathic inflammatory myopathies (IIMs) are lacking. Our objective was to document HRQoL and to identify factors associated … with a reduced HRQoL in patients with IIM. METHODS: A total of 1,715 patients (median age 49.9 years, 70% female, 87% white) who met probable or definite Bohan and Peter criteria or Griggs criteria for myositis were included from the Myovision registry. HRQoL was ascertained using the Short Form 12 (SF-12) health survey questionnaire. HRQoL physical component summary (PCS) and mental component summary (MCS) scores in relation to different patient and disease characteristics were compared to scores from matched normative data from the US general population and rheumatoid arthritis (RA) patients. Bivariate and multiple linear regression analyses were performed to assess the association between HRQoL and patient and disease parameters. RESULTS: The mean SF-12 summary scores were significantly lower in IIM patients than in the normative and RA populations. A diagnosis of inclusion body myositis, older age, patient-reported negative effect of disease on work, presence of another co-occurring autoimmune disease, polypharmacy, and IIM-associated lung disease and joint involvement were significantly associated with lower PCS scores. Lower MCS scores were associated with joint involvement and a negative effect of disease on work. CONCLUSION: In this large study of patient-reported outcomes in IIM, an association was found between multiple disease characteristics and reduced HRQoL, mostly in the physical domain. In the US, the HRQoL of IIM patients was found to be lower than that of the general population and RA patients.

2017 European League Against Rheumatism/American College of Rheumatology Classification Criteria for Adult and Juvenile Idiopathic Inflammatory Myopathies and Their Major Subgroups

Abstract (Expand)

OBJECTIVE: To develop and validate new classification criteria for adult and juvenile idiopathic inflammatory myopathies (IIM) and their major subgroups. METHODS: Candidate variables were assembled … from published criteria and expert opinion using consensus methodology. Data were collected from 47 rheumatology, dermatology, neurology, and pediatric clinics worldwide. Several statistical methods were utilized to derive the classification criteria. RESULTS: Based on data from 976 IIM patients (74% adults; 26% children) and 624 non-IIM patients with mimicking conditions (82% adults; 18% children), new criteria were derived. Each item is assigned a weighted score. The total score corresponds to a probability of having IIM. Subclassification is performed using a classification tree. A probability cutoff of 55%, corresponding to a score of 5.5 (6.7 with muscle biopsy) "probable IIM," had best sensitivity/specificity (87%/82% without biopsies, 93%/88% with biopsies) and is recommended as a minimum to classify a patient as having IIM. A probability of >/=90%, corresponding to a score of >/=7.5 (>/=8.7 with muscle biopsy), corresponds to "definite IIM." A probability of <50%, corresponding to a score of <5.3 (<6.5 with muscle biopsy), rules out IIM, leaving a probability of >/=50-<55% as "possible IIM." CONCLUSION: The European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria for IIM have been endorsed by international rheumatology, dermatology, neurology, and pediatric groups. They employ easily accessible and operationally defined elements, and have been partially validated. They allow classification of "definite," "probable," and "possible" IIM, in addition to the major subgroups of IIM, including juvenile IIM. They generally perform better than existing criteria.

Incidence and Mortality of Physician-Diagnosed Primary Sjogren Syndrome: Time Trends Over a 40-Year Period in a Population-Based US Cohort

Abstract (Expand)

OBJECTIVE: To estimate the incidence and mortality rates, and their evolution over time, of physician-diagnosed primary Sjogren syndrome (pSS) in residents of Olmsted County, Minnesota. PATIENTS AND … METHODS: Medical records of patients with a diagnosis or suspicion of SS in Olmsted County from January 1, 2006, through December 31, 2015, were reviewed to identify incident cases of pSS (defined by physician diagnosis). These cases were combined with those from a 1976 through 2005 incident cohort (n=111) from the same population. Incidence rates were age and sex adjusted to the 2010 US white population. Survival rates were compared with the expected rates in the population of Minnesota. RESULTS: With 61 incident cases of pSS diagnosed in Olmsted County from 2006 through 2015, the total cohort included 172 patients with incident pSS from 1976 through 2015. Of the 172 patients, 151 (88%) were women and 161 (94%) were white, with a mean +/- SD age at diagnosis of 58.3+/-16.7 years. The average age- and sex-adjusted annual incidence for 2006 through 2015 was 5.9 per 100,000 population (95% CI, 4.4-7.4 per 100,000 population), and the overall incidence for the entire period was 5.8 per 100,000 (95% CI, 4.9-6.6 per 100,000). The incidence increased with calendar time over the 40-year period (P=.005). There was no difference in mortality in the pSS cohort compared with expected (standardized mortality ratio, 1.15; 95% CI, 0.86-1.50). CONCLUSION: The average annual incidence of pSS in this population-based cohort was 5.8 per 100,000, with a progressive increase over the 40 years of the study. Overall survival of patients with pSS was not different from that of the general population.

Prevalence of Primary Sjogren’s Syndrome in a US Population-Based Cohort

Abstract (Expand)

OBJECTIVE: To report the point prevalence of primary Sjogren’s syndrome (SS) in the first US population-based study. METHODS: Cases of all potential primary SS patients living in Olmsted County, … Minnesota, on January 1, 2015, were retrieved using Rochester Epidemiology Project resources, and ascertained by manual medical records review. Primary SS cases were defined according to physician diagnosis. The use of diagnostic tests was assessed and the performance of classification criteria was evaluated. The number of prevalent cases in 2015 was also projected based on 1976-2005 incidence data from the same source population. RESULTS: A total of 106 patients with primary SS were included in the study: 86% were female, with a mean +/- SD age of 64.6 +/- 15.2 years, and a mean +/- SD disease duration of 10.5 +/- 8.4 years. A majority were anti-SSA positive (75%) and/or anti-SSB positive (58%), but only 22% met American-European Consensus Group or American College of Rheumatology criteria, because the other tests required for disease classification (ocular dryness objective assessment, salivary gland functional or morphologic tests, or salivary gland biopsy) were rarely performed in clinical practice. According to the physician diagnosis, the age- and sex-adjusted prevalence of primary SS was 10.3 per 10,000 inhabitants, but according to classification criteria, this prevalence was only 2.2 per 10,000. The analysis based on previous incidence data projected a similar 2015 prevalence rate of 11.0 per 10,000. CONCLUSION: The prevalence of primary SS in this geographically well-defined population was estimated to be between 2 and 10 per 10,000 inhabitants. Physicians rarely used tests included in the classification criteria to diagnose the disease in this community setting.
