    Antinuclear and antiphospholipid antibodies versus disease manifestations and clinical outcomes in systemic lupus erythematosus

    No full text
    Systemic lupus erythematosus (SLE) has an exceptionally heterogeneous clinical spectrum, ranging from mild disease limited to skin and joints to severe manifestations with renal disorder, central nervous system disease, severe cytopenias and thromboembolic events. Important clinical challenges include the prediction of disease flares and the identification of individuals that are likely to evolve severe disease with accrual of organ damage and worse prognosis. Autoantibodies, i.e. antinuclear antibodies (ANA) and antiphospholipid antibodies (aPL), and interferon alpha (IFN-α) that contribute to formation of immune complexes with nuclear antigens, are hallmarks considered to drive the disease in a vicious circle of antigen exposure, autoantibody production, inflammation and organ damage. There are few good biomarkers to predict severe SLE and organ damage. The aim of this PhD project was thus to increase the knowledge regarding ANA as well as aPL, and other potential biomarkers in relation to clinical features and disease outcomes in SLE. As expected, we found that the homogeneous ANA staining pattern was most common, and that it was associated with the occurrence of the ‘immunological disorder’ criterion. Speckled ANA was the second most common staining pattern, and it was inversely associated with arthritis, the ‘immunological disorder’ criterion and organ damage (Paper I). We also demonstrated that a considerable proportion of the patients lost ANA-positivity over time, whereas consistent staining patterns were most frequent (Paper V). Survival of patients with SLE has improved. Yet, in comparison to the general population, irreversible organ damage and increased mortality remains a critical concern. In Paper II, our cross-sectional analysis showed that more than a quarter of the patients had any aPL isotype (IgG, IgM or IgA class), and 14% were classified with antiphospholipid antibody syndrome (APS). A positive lupus anticoagulant (LA) test and/or IgG aPL tests were associated with most APS-related events and organ damage. Lupus nephritis, tobacco smoking, LA-positivity and the use of statins and/or corticosteroids were strongly associated with damage accrual, while hydroxychloroquine seemed to be protective. IgA aPL was not uncommon (16%) in Swedish cases of SLE, and analysis of IgA aPL may add information among clinically suspected APS-patients testing negative for LA and other aPL isotypes. Despite modern management and tax-funded health care with universal access, almost two thirds of the patients accrued organ damage over time, and the main causes of death were identified as malignancy, infection, and cardiovascular disease. We could confirm well established risk factors for organ damage such as APS, hypertension, and/or the use of corticosteroids, but we also observed that other factors such as pericarditis, haemolytic anaemia, lymphopenia and myositis seems to be of importance in this view (Paper IV). We also demonstrated that levels of the extracellular matrix protein osteopontin (OPN) was correlated with disease activity in patients with recent-onset SLE. In addition, OPN levels reflected global organ damage and were associated with APS and could have potential as a valuable biomarker in SLE (Paper III). Additional studies are warranted to further establish the clinical and mechanistic relevance of ANA seroconversion, OPN, as well as the importance of IgA aPL. Vigilance for malignancies, a restricted use of corticosteroids and prevention of cardiovascular disease and APS events are among modifiable factors to prevent organ damage and premature mortality. This thesis emphasizes the importance of autoantibodies in the pathogenesis, and diagnosis, of SLE. The autoantibody profile can be of great importance for tailored therapy in order to minimize the risk of organ damage accrual, morbidity as well as mortality.Ytterligare forskingsfinansiärer: Ingegerd Johanssons donation, Selanders stiftelse, Ingrid Asps stiftelse, StiftelsenProfessor Nanna Svartz fond, Stiftelsen Konung Gustaf V:s 80-årsfond och Konung Gustaf V:s och Drottning Victorias Frimurarstiftelse.</p

    Longitudinal Analysis of Anti-cardiolipin and Anti-beta 2-glycoprotein-I Antibodies in Recent-Onset Systemic Lupus Erythematosus : A Prospective Study in Swedish Patients

    Background: Anti-phospholipid syndrome (APS) and systemic lupus erythematous (SLE) are autoimmune disorders that often co-occur. Anti-phospholipid antibodies (aPL) are typical of both conditions and may be associated with vascular events and pregnancy-related morbidities. Whereas, aPL-screening is mandatory for individuals with suspected SLE, the clinical value of longitudinal aPL analyses in established SLE is unclear. Methods: We investigated the occurrence and variation of IgG/IgA/IgM anti-cardiolipin (aCL) and anti-beta 2-glycoprotein-I (anti-beta 2GPI) antibodies, using both the manufacturers cut-off and a cut-off based on the 99th percentile of 400 apparently healthy donors, in recent-onset SLE. Furthermore, we evaluated the relationships between aPL levels and SLE/APS manifestations, as well as the pharmacotherapy. Patients with SLE who met validated classification criteria were included in this prospective study (N = 54). Samples were obtained at 0, 6, 12, 24, 36, 48, 60, 72, 84, and 96 months after SLE diagnosis. Results: Depending on the cut-off applied, 61.1 or 44.4% showed a positive result for at least one aPL isotype or the lupus anticoagulant test over time. Median values for all six aPL isotypes numerically decreased from inclusion to last follow-up, but none of the isotypes met statistical significance. Seroconversion (from positive to negative, or the opposite direction) was occasionally seen for both aCL and anti-beta 2GPI. IgA and IgM anti-beta 2GPI were the most common isotypes, followed by IgM aCL. Presence of IgG aCL associated significantly with myocardial infarction and miscarriage, and IgG/IgA anti-beta 2GPI with miscarriage. Conclusion: aPL were common during the first years of SLE. Even though the levels fluctuated over time, the patients tended to remain aPL positive or negative. Repeated aPL testing in the absence of new symptoms seems to be of uncertain value in patients with recent-onset SLE.Funding Agencies|Swedish Rheumatism Association; Region Ostergotland (ALF Grants); King Gustaf Vs 80-year Anniversary Foundation; King Gustaf V and Queen Victorias Freemasons Foundation</p

    Objective Antinuclear antibody (ANA) analysis by immunofluorescence (IF) microscopy remains a diagnostic hallmark of systemic lupus erythematosus (SLE). The clinical relevance of ANA fine-specificities in SLE has been addressed repeatedly, whereas studies on IF-ANA staining patterns in relation to disease manifestations are very scarce. This study was performed to elucidate whether different staining patterns associate with distinct SLE phenotypes. Design Observational cohort study. Setting One university hospital rheumatology unit in Sweden. Participants The study population consisted of 222 cases (89% women; 93% Caucasians), where of 178 met ≥4/11 of the 1982 American College of Rheumatology (ACR-82) criteria. The remaining 20% had an SLE diagnosis based on positive IF-ANA (HEp-2 cells) and ≥2 typical organ manifestations at the time of diagnosis (Fries’ criteria). Outcome measures The IF-ANA staining patterns homogenous (H-ANA), speckled (S-ANA), combined homogenous and speckled (HS-ANA), centromeric (C-ANA), nucleolar (N-ANA)±other patterns and other nuclear patterns (oANA) were related to disease manifestations and laboratory measures. Antigen-specificities were also considered regarding double-stranded DNA (Crithidia luciliae) and the following extractable nuclear antigens: Ro/SSA, La/SSB, Smith antigen (Sm), small nuclear RNP (snRNP), Scl-70 and Jo-1 (immunodiffusion and/or line-blot technique). Results 54% of the patients with SLE displayed H-ANA, 22% S-ANA, 11% HS-ANA, 9% N-ANA, 1% C-ANA, 2% oANA and 1% were never IF-ANA positive. Staining patterns among patients meeting Fries’ criteria alone did not differ from those fulfilling ACR-82. H-ANA was significantly associated with the 10th criterion according to ACR-82 (‘immunological disorder’). S-ANA was inversely associated with arthritis, ‘immunological disorder’ and signs of organ damage. Conclusions H-ANA is the dominant IF-ANA pattern among Swedish patients with SLE, and was found to associate with ‘immunological disorder’ according to ACR-82. The second most common pattern, S-ANA, associated negatively with arthritis and organ damage

    Objective Definitions of remission in systemic lupus erythematosus (SLE; DORIS (1A/1B/2A/2B)), disease activity assessments and patient-reported outcome measures (PROMs) are useful in shared decision making between patients with SLE and physicians. We used longitudinal registry data from well-characterized Swedish patients with recent-onset SLE to explore potential correlations between DORIS status or disease activity, and PROMs. Methods Patients from the Clinical Lupus Register in North-Eastern Gothia, Sweden, who fulfilled the 1982 American College of Rheumatology and/or the 2012 Systemic Lupus International Collaborating Clinics classification criteria without prior organ damage, were enrolled at diagnosis. Data on treatments, serology, remission status (DORIS), disease activity (SLE Disease Activity Index-2000 (SLEDAI-2K)) and PROMs (quality of life: EuroQoL-5 Dimensions (EQ-5D); pain intensity, fatigue and well-being: visual analog scale (VAS) 0-100 mm) were collected during rheumatology clinic visits at months 0 (diagnosis), 6, 12, 24, 36, 48 and 60. Correlations were assessed using Pearson correlation and/or beta regression coefficients. Results A total of 41 patients were enrolled (median age = 39 years, 80% female, 85% white). Achievement of DORIS 1A and 2A (neither of which includes serology) significantly correlated with all PROMs (EQ-5D: p &amp;lt;= 0.02; pain: p = 0.0001; fatigue: p = 0.0051; well-being: p &amp;lt; 0.0001). Disease activity measures were correlated with VAS pain intensity (p &amp;lt; 0.03) and VAS well-being (p &amp;lt; 0.04). Conclusions Our findings illustrate the importance of the interplay between remission, disease activity assessments and PROMs. PROMs may be a useful tool in clinical practice, being administered prior to patient visits to streamline clinical care.Funding Agencies|Bristol-Myers SquibbBristol-Myers Squibb; Swedish Rheumatism Association; King Gustaf Vs 80-year Anniversary foundation; King Gustaf V and Queen Victorias Freemasons foundation; Region _Osterg_otland (ALF Grants)</p

    The majority of Swedish systemic lupus erythematosus patients are still affected by irreversible organ impairment: factors related to damage accrual in two regional cohorts

    No full text
    Background Although the survival of patients with systemic lupus erythematosus (SLE) has improved, irreversible organ damage remains a critical concern. We aimed to characterize damage accrual and its clinical associations and causes of death in Swedish patients. Methods Accumulation of damage was evaluated in 543 consecutively recruited and well-characterized cases during 1998-2017. The Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology damage index (SDI) was used to estimate damage. Results Organ damage (SDI amp;gt;= 1) was observed in 59%, and extensive damage (SDI amp;gt;= 3) in 25% of cases. SDI amp;gt;= 1 was significantly associated with higher age at onset, SLE duration, the number of fulfilled SLICC criteria, neurologic disorder, antiphospholipid antibody syndrome (APS), hypertension, hyperlipidemia, depression and secondary Sjogrens syndrome (SS). In addition, SDI amp;gt;= 3 was associated with serositis, renal and haematological disorders and interstitial lung disease. A multiple regression model identified not only well-known risk factors like APS, antihypertensives and corticosteroids, but pericarditis, haemolytic anaemia, lymphopenia and myositis as being linked to SDI. Malignancy, infection and cardiovascular disease were the leading causes of death. Conclusions After a mean SLE duration of 17 years, the majority of todays Swedish SLE patients have accrued damage. We confirm previous observations and report some novel findings regarding disease phenotypes and damage accrual.Funding Agencies|Swedish Rheumatism Association; County Council of Ostergotland; Swedish Society of Medicine; King Gustaf Vs 80-year Anniversary foundation; King Gustaf V and Queen Victorias Freemasons foundation; Ingegerd Johansson donation; Selander foundation; County Council of Uppsala</p

    Increase in stress contributes to impaired jaw function in juvenile idiopathic arthritis : a two-year prospective study

    No full text
    BackgroundStress in patients with Juvenile Idiopathic Arthritis (JIA) has been found to be associated with orofacial pain, psychological distress, jaw dysfunction and loss of daily activities in a cross-sectional study. The aim of this study was to investigate the relations between stress and change of stress over time versus changes in orofacial pain, psychosocial factors and jaw function over a two-year period in patients with JIA.MethodsThis is a two-year prospective follow-up study involving 40 JIA patients. At baseline (2015) the median age was 12 years and at two-year follow up (2018) 14 years. The JIA patients were examined clinically and with questionnaires at baseline and follow-up with the diagnostic criteria for temporomandibular disorders (DC/TMD) and completed the same set of DC/TMD questionnaires regarding orofacial pain symptoms and psychosocial factors.ResultsChange in stress was associated with change in catastrophizing, psychological distress as well as limitation in general function and jaw function.ConclusionsThis study emphasizes the importance of maintaining a low stress level in patients with JIA since an increase in stress level over a two-year period seems to impair jaw function as well as psychological distress and catastrophizing

    Osteopontin is associated with disease severity and antiphospholipid syndrome in well characterised Swedish cases of SLE

    No full text
    Objective The variety of disease phenotypes among patients with SLE challenges the identification of new biomarkers reflecting disease activity and/or organ damage. Osteopontin (OPN) is an extracellular matrix protein with immunomodulating properties. Although raised levels have been reported, the pathogenic implications and clinical utility of OPN as a biomarker in SLE are far from clear. Thus, the aim of this study was to characterise OPN in SLE. Methods Sera from 240 well-characterised adult SLE cases classified according to the American College of Rheumatology (ACR) and/or the Systemic Lupus International Collaborating Clinics (SLICC) criteria, and 240 population-based controls were immunoassayed for OPN. The SLE Disease Activity Index 2000 (SLEDAI-2K) was used to evaluate disease activity and the SLICC/ACR Damage Index (SDI) to detect damage accrual. Results Serum OPN levels were in average raised fourfold in SLE cases compared with the controls (p&lt;0.0001). OPN correlated with SLEDAI-2K, especially in patients with a disease duration of &lt;12 months (r=0.666, p=0.028). OPN was highly associated with SDI (p&lt;0.0001), especially in the renal (p&lt;0.0001), cardiovascular (p&lt;0.0001) and malignancy (p=0.012) domains. Finally, OPN associated with coherent antiphospholipid syndrome (APS; p=0.009), and both clinical and laboratory criteria of APS had significant positive impact on OPN levels. Conclusions In this cross-sectional study, circulating OPN correlates with disease activity in recent-onset SLE, reflects global organ damage and associates with APS. Longitudinal studies to dissect whether serum OPN also precedes and predicts future organ damage are most warranted

    NET Formation in Systemic Lupus Erythematosus : Changes during the COVID-19 Pandemic

    No full text
    The severity of the coronavirus disease in 2019 (COVID-19) is strongly linked to a dysregulated immune response. This fuels the fear of severe disease in patients with autoimmune disorders continuously using immunosuppressive/immunomodulating medications. One complication of COVID-19 is thromboembolism caused by intravascular aggregates of neutrophil extracellular traps (NETs) occluding the affected vessels. Like COVID-19, systemic lupus erythematosus (SLE) is characterized by, amongst others, an increased risk of thromboembolism. An imbalance between NET formation and clearance is suggested to play a prominent role in exacerbating autoimmunity and disease severity. Serologic evidence of exposure to SARS-CoV-2 has a minor impact on the SLE course in a Swedish cohort reportedly. Herein, we assessed NET formation in patients from this cohort by neutrophil elastase (NE) activity and the presence of cell-free DNA, MPO-DNA, and NE-DNA complexes and correlated the findings to the clinical parameters. The presence of NE-DNA complexes and NE activity differed significantly in pre-pandemic versus pandemic serum samples. The latter correlated significantly with the hemoglobin concentration, blood cell counts, and complement protein 3 and 4 levels in the pre-pandemic but only with the leukocyte count and neutrophil levels in the pandemic serum samples. Taken together, our data suggest a change, especially in the NE activity independent of exposure to SARS-CoV-2.Funding Agencies|German Research Foundation (DFG) 2886 PANDORA [B3, CRC1181-261193037 (C03), TRR241 (B04)]; H2020-FETOPEN-2018-2019-2020-01 [861878]; Volkswagen-Stiftung [97744]; MIIC (Medical Infection and Inflammation Center, Linkoping University); MIIC (Region Ostergotland) (MIIC-2021); Swedish Rheumatism Association [R-939149]; Region Ostergotland (ALF Grants) [RO-960604]; Swedish Society of Medicine [SLS-590231]; Gustafsson Foundation; King Gustaf Vs 80-year Anniversary foundation [FAI-2020-0663]; King Gustaf V and Queen Victorias Freemasons foundation</p
