- Objective: Both psoriatic arthritis (PsA) and rheumatoid arthritis (RA) have a significant impact on quality of life, but few reports have compared the two diseases. The current study assessed health-related quality of life (HRQoL) in PsA at diagnosis and after five years compared with early rheumatoid arthritis (RA) and a matched general population. Methods: Patients with early PsA and early RA included in two Swedish registries with HRQoL data measured by the Medical Outcomes Study Short Form 36 (SF-36) at baseline and at five years follow-up were included. Differences in SF-36 scores compared with the general population were calculated for each patient. Physical function, disease activity, the delay before diagnosis, pain, and general wellbeing were used as explanatory variables. Statistical tests included t-tests and univariate and multivariate linear regression. Results: PsA (n = 166) and RA (n = 133) patients of both sexes had significantly reduced HRQoL at disease onset. After five years, PsA patients still had impairments in several domains of SF-36, whereas RA patients had an almost normalized HRQoL. The time from symptom onset to diagnosis, disease activity, and disability independently contributed to the reduced improvement in PsA. Conclusion: Both early PsA and RA are characterized by severely reduced HRQoL. Despite more severe disease at inclusion, normalization of HRQoL is seen in patients with RA but not PsA. This may be due to delay in the diagnosis of PsA or more powerful interventions in RA. Earlier detection, lifestyle intervention, and more aggressive management strategies may be needed for PsA.

Early rheumatoid arthritis : biomarkers and hormonal factors in relation to disease progression
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Rheumatoid arthritis (RA) is a chronic inflammatory joint disease, affecting approximately 0.5 to 1% of the adult population. Although the aetiology is not fully known, a complex interaction between genetic, environmental and stochastic factors is thought to trigger the pathogenic mechanisms. A distinguishing feature of RA is the presence of disease associated autoantibodies, mainly rheumatoid factor (RF) and anti-cyclic citrullinated antibodies (ACPA), which are important in both diagnostic and prognostic purpose. The disease is systemic but primarily affects the joints, and can cause irreversible destructions of cartilage and bone, eventually leading to functional disabilities. Moreover, extra-articular features (i.e., symptoms outside the joints) can occur and the patients have an increased risk for comorbidities, predominantly cardiovascular disease. Since the disease is heterogenous, varying from mild to more severe forms, the prognosis can be difficult to predict. Improvements in early diagnosis and identification of patients at risk of a more severe disease course can lead to better outcomes for the patients. The overall aim of this thesis was to evaluate prognostic biomarkers, and to evaluate hormonal and reproductive factors in relation to cardiovascular events (CVE) in patients with newly diagnosed RA (symptoms <12 months).Methods: The patients were included in a prospective inception cohort from the years of 1996 to 2017 and followed-up regularly at the early RA clinics in the northern region of Sweden. Clinical and laboratory parameters, and treatment were regularly recorded in the Swedish Rheumatology Quality Register (SRQ). Enzyme-linked immunosorbent assays (ELISA) and a multiplex assay were used to analyse bone remodelling factors and ACPA reactivities, respectively. Questionnaires regarding hormonal and reproductive factors were sent out to female patients ≤80 years. Information of CVE was extracted from the Swedish National Health Register and Cause of Death Register. Potential markers for disease progression i.e., bone remodelling factors and autoantibodies were analysed in relation to disease progression. Hormonal and reproductive factors were analysed in relation to CVE. Results: In paper I we found associations between receptor activator of nuclear factor kappa-B (RANKL), a central molecule of bone metabolism, and radiological findings at baseline, 24 months, and radiological progression analysed in 407 RA patients. The combination of RANKL and anti-CCP positivity indicated a more severe disease course in terms of joint destruction. Sclerostin was not associated with radiological outcome. Polymorphisms of the genes for sclerostin (SOST) and RANKL (TNFSF11) did not show significant associations with radiological outcome or with the concentrations, respectively. In paper II, we found that even though antibody status is considered in clinical practice and modern treatment reduces disease activity, the radiographic joint damage remained increased among anti-CCP positive patients. In paper III, 22 different ACPA reactivities were analysed in relation to disease courses of RA. The presence of a higher number of different ACPA reactivities, and different ACPA subtypes could provide prognostic information of disease activity and radiological destruction. In paper IV, we found that hormonal and reproductive factors were associated with CVE in female patients. A higher number of childbirths increased the risk for CVE, whilst oral contraceptives decreased the risk. The majority of patients with later CVE had their RA disease onset after menopause and had a longer duration from menopause until RA onset.Conclusion: RANKL can function as a prognostic marker for the disease course of RA. Even though anti-CCP antibodies are taken into account in clinical practice and treatment reduce disease activity, the joint damage can progress, supporting the direct bone degrading effects by ACPA. The number of, and different subtypes of ACPA, can predict different disease progression. These markers can be valuable to identify patients at need for more aggressive treatment and careful radiographic monitoring, even if disease activity is under control. Finally, hormonal factors such as childbirths, oral contraceptives and the timing of RA onset in relation to hormonal status can add value for the evaluation of CVE risk in female RA patients.

Tidskriftsartikel (refereegranskat)abstract
- Hormonal and reproductive factors affect the risk for cardiovascular events (CVE) in the general population. Although the risk of CVE is increased in rheumatoid arthritis (RA), the knowledge about the impact of hormonal factors for CVE in RA is sparse. Female postmenopausal patients ≤80 years with early RA were consecutively included in this observational study (n = 803) between 1 January 1996 until 31 December 2017. Questionnaires regarding hormonal factors were distributed from the index date. Data regarding CVE were obtained from the Swedish National Health Register and Cause of Death Register. Associations between CVE and hormonal factors were analyzed using Cox proportional hazard regression. Of the postmenopausal women, 64 women had a CVE after RA onset. The time period from menopause to RA onset was significantly longer for CVE cases with higher proportion of postmenopausal women. In Cox proportional hazard regression models, years from last childbirth and multiparity were associated with higher CVE risk. Adjustments for traditional risk factors did not affect the results except for hypertension. RA onset after menopause and a longer duration from menopause until onset increased the CVE risk. Multiparity was associated with higher CVE risk whilst oral contraceptives decreased the risk. These results can contribute to identification of high-risk patients for CVE beyond traditional risk factors.

- Objectives To compare risks for COVID-19-related outcomes in inflammatory joint diseases (IJDs) and across disease-modifying antirheumatic drugs (DMARDs) during the first two waves of the pandemic and to assess effects of the pandemic on rheumatology care provision. Methods Through nationwide multiregister linkages and cohort study design, we defined IJD and DMARD use annually in 2015-2020. We assessed absolute and relative risks of hospitalisation or death listing COVID-19. We also assessed the incidence of IJD and among individuals with IJD, rheumatologist visits, DMARD use and incidence of selected comorbidities. Results Based on 115 317 patients with IJD in 2020, crude risks of hospitalisation and death listing COVID-19 (0.94% and 0.33% across both waves, respectively) were similar during both waves (adjusted HR versus the general population 1.33, 95% CI 1.23 to 1.43, for hospitalisation listing COVID-19; 1.23, 95% CI 1.08 to 1.40 for death listing COVID-19). Overall, biological disease-modifying antirheumatic drugs (bDMARDs)/targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs) did not increase risks of COVID-19 related hospitalisation (with the exception of a potential signal for JAK inhibitors) or death. During the pandemic, decreases were observed for IJD incidence (-7%), visits to rheumatology units (-16%), DMARD dispensations (+6.5% for bDMARD/tsDMARDs and -8.5% for conventional synthetic DMARDs compared with previous years) and for new comorbid conditions, but several of these changes were part of underlying secular trends. Conclusions Patients with IJD are at increased risk of serious COVID-19 outcomes, which may partially be explained by medical conditions other than IJD per se. The SARS-CoV-2 pandemic has exerted measurable effects on aspects of rheumatology care provision demonstrated, the future impact of which will need to be assessed.

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.

- In contrast to the increased mortality reported in other inflammatory diseases such as rheumatoid arthritis and psoriasis, prior mortality studies in psoriatic arthritis (PsA) have shown inconsistent results.Objectives:To compare all-cause mortality between PsA patients in Sweden and matched general population controls, and to describe cause of death distributions in the two groups.Methods:All individuals in Sweden with ≥1 main diagnosis of PsA (ICD-10: L40.5/M07.0-M07.3) from outpatient visits to rheumatology or internal medicine clinics at age ≥18 years (y) 2001-2017 were identified from the Swedish National Patient Register. Each case was matched to 5 general population controls based on sex, county and age in the year of the first registered arthritis diagnosis for the case. Cases and controls were followed from 1 Jan, 2007, or from first PsA diagnosis thereafter for index cases, until first occurrence of death (data from the Swedish Cause of Death Register), emigration or 31 Dec, 2018. Mortality was assessed overall, as well as stratified by sex (45% males) and disease duration (PsA diagnosis prior to 2007 [38% of cases] vs. 2007-2017), using matched Cox proportional hazard regression, or – in case the Cox assumption regarding proportionality did not hold – matched Breslow test. To account for potential PsA misclassification (in a previous validation study, 86% of 400 cases fulfilled PsA classification criteria), a sensitivity analysis was performed by randomly replacing 20% of cases with one of their own controls. Moreover, incidence rate ratios (IRR) of death were calculated overall and stratified by sex, disease duration and age. Finally, causes of death (from the Cause of Death Register) were described for PsA cases and controls.Results:Over the 12y follow-up, 3 121 deaths occurred among 33 036 PsA cases (268 402 person-years at risk) and 12 884 deaths among 161 144 controls (1 302 250 person-years), resulting in an increased mortality among the PsA cases (HR 1.11 [95%CI 1.07-1.16], p<0.001, Figure and Table; sensitivity analysis HR 1.09 [1.05-1.14]). The increased mortality was seen mainly among female PsA cases and among cases with longer disease duration (Figure; Table). IRR:s of death were significantly increased for all ages except <40y, with the numerically highest point-estimates for ages 40-49y and 50-59y (Table). Cause of death frequencies among the PsA cases/controls: cardiovascular disease 29/27%; diabetes mellitus 2.1/2.5%; chronic kidney disease 0.4/0.3%; infection 5.7/4.5%; chronic pulmonary disease 5.1/4.1%; malignancy 29/34%; suicide 2.3/2.0%; other 27/26%.Table 1.Mortality rates and incidence rate ratiosPsA casesPopulation controlsNumber of deathsPerson-yearsat riskMortality rate*Number of deathsPerson-yearsat riskMortality rate*Incidence rate ratio (95%CI)Overall3 121268 40211.612 8841 302 2509.91.18 (1.13-1.22)Males1 459120 51712.16 468580 28511.11.09 (1.03-1.15)Females1 662147 88611.26 416721 9668.91.27 (1.20-1.34)Longer disease duration1 943139 37913.97 459670 17411.11.25 (1.19-1.32)Shorter disease duration1 178129 0239.15 425632 0778.61.06 (1.00-1.13)Age intervals (years)<401833 5680.598163 2780.60.89 (0.54-1.48)40-499050 5521.8322246 9551.31.37 (1.08-1.73)50-5928065 8204.31 131321 7303.51.21 (1.06-1.38)60-6972370 22410.33 132341 5879.21.12 (1.04-1.22)70-7996037 23225.84 160178 90923.31.11 (1.03-1.19)≥801 05011 00795.44 04149 79181.21.18 (1.10-1.26)* Per 1000 person-years.Conclusion:In this nationwide 12y assessment, the mortality risk among PsA patients in Sweden was increased by around 10% as compared to the general population, mainly driven by increased risks among females and patients with longer disease duration.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The Swedish Rheumatology Quality Register has implemented an internet-based method (PER) for registering patient-recorded outcome measures. The aim of this study was to compare the agreement between visual analogue scales (VASs) reported via PER and clinic-based reporting using paper forms.Methods: In a cross-sectional study (70 patients), the results of 79 registrations of VASs for global health, pain, and fatigue from PER were compared with corresponding clinic-based paper registrations. For patients with polyarthritis, 28-joint count Disease Activity Scores (DAS28) were computed. Patients with axial disease also completed Bath Ankylosing Spondylitis Disease Activity Index and Functional Index (BASDAI and BASFI) questionnaires. Mean differences and intraclass correlation coefficients (ICCs) were calculated. Agreement was visualized using Bland-Altman plots.Results: No statistically significant differences in VASs were found comparing PER and paper forms for VAS Global, VAS Pain, and VAS Fatigue (p=0.295, 0.463, and 0.288, respectively). ICCs for VAS Global, Pain, and Fatigue ranged from 0.889 to 0.952, indicating excellent agreement. Bland-Altman plots for VAS did not show any proportional bias. The mean difference for DAS28 calculated by VASs from paper vs PER was -0.02 (n=65, p =0.660), and the mean difference for BASDAI was 0.04 (n=11, p =0.742). ICCs for DAS28 and BASDAI were 0.962 and 0.985, respectively. Of the participating patients, 60% preferred PER.Conclusion: Internet-based reporting for patient-reported outcomes in a clinical setting resulted in similar data for VASs and corresponding disease activity scores to clinic-based reporting on paper forms.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Psoriatic arthritis (PsA) is a heterogeneous inflammatory disease associated with psoriasis. Underlying genetic factors are considered important for disease expression and prognosis of PsA. Interleukin-1β-regulating protein complexes called inflammasomes are associated with several inflammatory diseases, e.g. rheumatoid arthritis and psoriasis. The aim was to determine whether inflammasome-related genetic variation is associated with PsA susceptibility or different disease phenotypes.Method: DNA from 724 patients with PsA and 587 population-based controls from northern Sweden was analysed for single-nucleotide polymorphisms in NLRP3-Q750K (rs35829419), NLRP3 (rs10733113), CARD8-C10X (rs2043211), NLRP1 (rs8079034), and NLRP1 (rs878329).Results: Significant associations were found with the genotype AA (vs AT+TT) of rs2043211 for PsA patients compared with controls [odds ratio (OR), 95% confidence interval (CI) 1.32 (1.05–1.65), p = 0.016]; and between the C-allele of rs878329 and axial involvement of PsA [OR (95% CI) 1.37 (1.02–1.84), p = 0.035], the T-allele of rs8079034 with prescription of conventional synthetic disease-modifying anti-rheumatic drugs [OR (95% CI) 1.76 (1.23–2.53), p = 0.0020], the G-allele of rs10733113 and patients with a skin disease with early onset [OR (95% CI) 1.58 (1.13–2.21), p = 0.007], and the C-allele of rs35829419 and a destructive/deforming disease [OR (95% CI) 1.63 (1.04–2.55), p = 0.030].Conclusions: This study is the first to show an association with a genetic polymorphism in an inflammasome-related gene, CARD8-C10X (rs2043211), in patients with PsA. Associations between different phenotypes of PsA and different polymorphisms of the inflammasome genes were also found. Our results indicate the involvement of inflammasome genes in the pathogenesis and disease expression of PsA.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: The bile salt-stimulated lipase (BSSL) is a hitherto unrecognized player in inflammation. Animals devoid of BSSL (knockout mice) are protected from developing collagen induced arthritis (CIA) and collagen antibody induced arthritis (CAIA), and antibodies directed towards BSSL has been proven to prevent or mitigate arthritis in mouse and rat arthritis models1. In humans, BSSL is present in blood2 and accumulate at sites of inflammation. Patients with acute pancreatitis have significantly increased plasma BSSL levels compared to healthy controls. Whether BSSL in blood originates from pancreas, inflammatory cells, or both remains to be elucidated.Objectives: To determine BSSL concentration in blood samples from patients with inflammatory joint disorders and to evaluate possible relationships between circulating BSSL levels and disease-activity variables.Methods: BSSL concentrations in plasma or serum were determined in patients with rheumatoid arthritis (RA), psoriasis arthritis (PsA), and juvenile idiopathic arthritis (JIA) by a sandwich enzyme-linked immunosorbent assay (ELISA). Correlations between BSSL concentrations and disease activity score, erythrocyte sedimentation rate (ESR), blood levels of C-reactive protein (CRP), S100A8/9, leukocyte- and neutrophil counts, proinflammatory cytokines and chemokines were analyzed using Spearman rank-order correlation.Results: Significant correlations between BSSL concentration in plasma and disease activity score (DAS28, rS=0.31, p=0.007), ESR (rS=0.58, p<0.000), CRP (rS=0.42, p=0.012), leukocytes (rS=0.66, p<0.000), and neutrophils (rS=0.71, p<0.000) were found in RA. The BSSL plasma concentration decreased with duration of treatment with the TNFα inhibitor infliximab, in parallel with decreasing DAS28 score.BSSL concentration was significantly higher in sera from PsA patients with both oligo- and polyarthritis compared with healthy controls. Moreover, BSSL concentration in serum correlated significantly with S100A8/A9 and CRP concentrations (rS=0.54, p<0.001 and rS=0.49, p<0.001, respectively). No correlation between levels of BSSL and cytokines or chemokines were found in RA or PsA plasma or serum, respectively.In JIA, levels of BSSL in serum correlated significantly with JIA disease activity score (JADAS27) (rS=0.26, p=0.007), ESR (rS=0.47, p<0.000), and leukocytes (rS=0.32, p<0.000).Conclusion: BSSL concentration in serum and plasma correlated with disease activity in patients with inflammatory joint disorders, i.e. RA, PsA and JIA. These data in humans support the relevance of our previous studies in rodents and therefore also our hypothesis 1 that BSSL is a novel target for treatment of inflammatory diseases.

Tidskriftsartikel (refereegranskat)abstract
- The bile salt-stimulated lipase (BSSL) was originally recognized as a lipolytic enzyme expressed by the exocrine pancreas and in some species, notably humans, the lactating mammary gland, being secreted into the duodenum and with the mother’s milk, respectively. However, BSSL is also present in the blood and has been assigned additional functions, even beyond the gastrointestinal tract. Conventional BSSL knockout mice are protected from developing disease in animal models of arthritis, and antibodies directed towards BSSL prevent or mitigate disease in similar models. The aim of this study was to investigate the role of BSSL as a newly discovered player in inflammation and specifically in inflammatory joint disorders. As part of mechanism of action, we here show that BSSL is secreted by neutrophils, interacts with monocytes and stimulates their migration in vitro. An anti-BSSL antibody that blocks the human BSSL-monocyte interaction was shown to simultaneously prevent the signaling pathway by which BSSL induce cell migration. Moreover, in this cohort study we show that BSSL levels are significantly higher in blood samples from patients with rheumatoid arthritis and psoriatic arthritis compared to healthy controls. The BSSL levels in patients’ blood also correlated with disease activity scores and established inflammatory markers. Hence, although the mode of action is not yet fully clarified, we conclude that BSSL could be considered a proinflammatory component in the innate immune system and thus a possible novel target for treatment of chronic inflammation.

Tidskriftsartikel (refereegranskat)abstract
- IntroductionWe aimed to compare the proportions of patients with newly diagnosed psoriatic arthritis (PsA) and rheumatoid arthritis (RA) remaining on methotrexate (regardless of other disease-modifying antirheumatic drug (DMARD)-changes), and proportions not having started another DMARD (regardless of methotrexate discontinuation), within 2 years of starting methotrexate, as well as methotrexate effectiveness. MethodsPatients with DMARD-naive, newly diagnosed PsA, starting methotrexate 2011-2019, were identified from high-quality national Swedish registers and matched 1:1 to comparable patients with RA. Proportions remaining on methotrexate and not starting another DMARD were calculated. For patients with disease activity data at baseline and 6 months, response to methotrexate monotherapy was compared through logistic regression, applying non-responder imputation. ResultsIn total, 3642/3642 patients with PsA/RA were included. Baseline patient-reported pain and global health were similar, whereas patients with RA had higher 28-joint scores and evaluator-assessed disease activity. Two years after methotrexate start, 71% of PsA vs 76% of patients with RA remained on methotrexate, 66% vs 60% had not started any other DMARD, and 77% vs 74% had not started specifically a biological or targeted synthetic DMARD. At 6 months, the proportions of patients with PsA versus RA achieving pain-scores <= 15 mm were 26% vs 36%; global health <= 20 mm: 32% vs 42%; evaluator-assessed 'remission': 20% vs 27%, with corresponding adjusted ORs (PsA vs RA) of 0.63 (95% CI 0.47 to 0.85); 0.57 (95% CI 0.42 to 0.76) and 0.54 (95% CI 0.39 to 0.75). DiscussionIn Swedish clinical practice, methotrexate use is similar in PsA and RA, both regarding initiation of other DMARDs and methotrexate retention. On a group level, disease activity improved during methotrexate monotherapy in both diseases, although more so in RA.

- The clinical diagnosis of psoriatic arthritis (PsA) may be challenging. In Sweden, the vast majority of PsA cases are diagnosed within rheumatology or internal medicine (IM). Knowledge of the correspondence between clinical ICD diagnoses and classification criteria fulfillment is crucial to interpret studies identifying cases based on ICD codes.Objectives:To assess the degree to which patients with clinical PsA diagnoses in Sweden fulfill established PsA classification criteria.Methods:Four hundred patients with ≥1 outpatient physician visit to one of five rheumatology or IM departments (3 university/2 county departments, spread across Sweden) 2013-2015 with a main ICD-10 diagnosis of PsA (L40.5/M07.0-M07.3), were randomly selected from the Swedish National Patient Register (80 cases/site). Based on a structured medical record review, positive predictive values (PPV) of a clinical PsA diagnosis (i.e. ≥1 visit with a PsA ICD-10 code) for fulfillment of the following classification criteria were assessed: CASPAR,[1] Moll & Wright,[2] Vasey & Espinoza,[3] and Modified ESSG criteria for PsA,[4] respectively (as well as for any of these); ASAS criteria for peripheral or axial spondyloarthritis (SpA) [5]; and the 1987 ACR criteria for rheumatoid arthritis (RA).[6] Subanalyses regarding CASPAR fulfillment were also performed restricted to patients with available rheumatoid factor and peripheral X-ray status (central CASPAR items; n=227), and among patients with ≥2 ICD codes for PsA, of which ≥1 from a rheumatology/IM department (n=353).Results:Out of 400 clinically diagnosed PsA patients, 343 (86%) fulfilled any of the 4 PsA classification criteria, with a PPV for CASPAR fulfillment of 69% (rising to 73-82% in the subanalyses;Figure 1). Substantial overlap was seen regarding fulfillment of the 4 PsA criteria (Figure 2A). Moreover, 86% fulfilled the ASAS peripheral or axial SpA criteria, while the 1987 ACR definition of RA was met by 27% – in both cases with the great majority also classifiable as PsA (Figure 2B). Most patients not fulfilling any PsA criteria had either no verified arthritis or polyarticular disease (Table). Overall, only 6.5% of the clinical PsA diagnoses were judged as clearly wrong by the rheumatologists performing the medical record assessments.Conclusion:The validity of clinical ICD-10 diagnoses for PsA in the Swedish National Patient Register is good, with a PPV of 86% for the fulfillment of established PsA classification criteria.References:[1]Arthritis Rheum2006;54:2665-73[2]Semin Arthritis Rheum 1973;3:55-78[3]In: Calin A, editor.

- Objectives : Knowledge of the correspondence between clinical ICD diagnoses and classification criteria fulfilment is crucial to interpret studies identifying cases via ICD codes. We assessed the degree to which patients registered with ICD-10 diagnoses of psoriatic arthritis (PsA) in the Swedish National Patient Register (NPR) fulfil established PsA classification criteria. Method Four hundred patients with at least one outpatient visit to one of five rheumatology or internal medicine departments (three university/two county departments across Sweden) in 2013-2015, with a main ICD-10 diagnosis of PsA (L40.5-M07.3), were randomly selected (80 cases/site). Through a structured medical record review, positive predictive values (PPVs) for fulfilment of the following classification criteria were assessed: CASPAR, Moll and Wright, Vasey and Espinoza, and modified ESSG criteria for PsA. A subset analysis regarding CASPAR fulfilment was also performed among cases with available rheumatoid factor and peripheral X-ray status (central CASPAR items; n = 227). Results Of the 400 patients with a main ICD-10 diagnosis of PsA, 343 (86%) fulfilled at least one of the four PsA classification criteria. PPVs for the different criteria were: CASPAR 69% (82% in the subset analysis), Moll and Wright 51%, Vasey and Espinoza 76%, and modified ESSG 64%. Overall, only 6.5% of the 400 PsA diagnoses were judged as clearly incorrect by the medical record reviewers. Conclusion The validity of rheumatologist-made, clinical ICD-10 diagnoses for PsA in the Swedish NPR is good, with PPVs of 69-82% for CASPAR fulfilment and 86% for meeting any established PsA classification criteria.
