- Patients with SLE have increased risk of myocardial infarction (MI). Few studies have investigated the characteristics of SLE-related MIs. We compared characteristics of and risk factors for MI between SLE patients with MI (MI-SLE), MI patients without SLE (MI-non-SLE) and SLE patients without MI (non-MI-SLE) to understand underlying mechanisms.MethodsWe identified patients with a first-time MI in the Karolinska SLE cohort. These patients were individually matched for age and gender with MI-non-SLE and non-MI-SLE controls in a ratio of 1:1:1. Retrospective medical file review was performed. Paired statistics were used as appropriate.ResultsThirty-four MI-SLE patients (88% females) with a median age of 61 years were included. These patients had increased number of coronary arteries involved (p=0.04), and ≥50% coronary atherosclerosis/occlusion was numerically more common compared with MI-non-SLE controls (88% vs 66%; p=0.07). The left anterior descending artery was most commonly involved (73% vs 59%; p=0.11) and decreased (<50%) left ventricular ejection fraction occurred with similar frequency in MI-SLE and MI-non-SLE patients (45% vs 36%; p=0.79). Cardiovascular disease (44%, 5.9%, 12%; p<0.001) and coronary artery disease (32%, 2.9%, 0%; p<0.001), excluding MI, preceded MI/inclusion more commonly in MI-SLE than in MI-non-SLE and non-MI-SLE patients, respectively. MI-SLE patients had lower plasma albumin levels than non-MI-SLE patients (35 (29–37) vs 40 (37–42) g/L; p=0.002).ConclusionIn the great majority of cases, MIs in SLE are associated with coronary atherosclerosis. Furthermore, MIs in SLE are commonly preceded by symptomatic vascular disease, calling for attentive surveillance of cardiovascular disease and its risk factors and early atheroprotective treatment.

- Myocardial infarction (MI) is estimated to be 2- to 3-fold elevated in systemic lupus erythematosus (SLE) as compared to gender- and age-matched controls (1-2). Even though some risk factors have been purposed, mechanisms of increased MI incidence remains to be determined.Objectives:To explore underlying mechanisms, we compared MI characteristics and risk factors between SLE patients with MI (MI-SLE), MI patients without SLE (MI-nonSLE) and SLE patients without MI (nonMI-SLE).Methods:We performed retrospective medical file review including angiography and echocardiography reports in 34 MI-SLE patients, 34 MI-nonSLE patients and 34 nonMI-SLE patients – all individually matched for gender and age in a ratio of 1:1:1.Results:Median age was 61 years and 88% were females. MI-SLE patients had more coronary arteries involved (table 1; p=0.038), and ≥50% coronary atherosclerosis/occlusion at MI was numerically more common compared to MI-nonSLE controls (88% versus 66%; p=0.065). The left anterior descending artery was most frequently involved in both MI groups (73% versus 59%; p=0.11). Decreased (<50%) left ventricular ejection fraction occurred with similar frequency (45% versus 36%; p=0.79) in MI-SLE patients compared to MI-nonSLE patients. Cardiovascular disease (CVD) (44%, 5.9%, 12%; p<0.001) and coronary artery disease excluding MI (CAD, 32%, 2.9%, 0%; p<0.001) preceded MI/inclusion more commonly in MI-SLE than in MI-nonSLE and nonMI-SLE patients, respectively. MI-SLE patients differed from nonMI-SLE patients through lower plasma albumin levels (35 (29-37) versus 40 (37-42) g/L; p=0.002) and longer disease duration (22 (14-32) versus 14 (6.3-24) years; p=0.038).Conclusion:We demonstrate that non-procedural MIs in SLE are in 88% of cases associated with significant coronary atherosclerosis. Increased prevalence of CAD prior MI and higher number of coronary arteries involved at MI, suggest accelerated coronary atherosclerosis in SLE patients. This calls for attentive surveillance of CVD and early atheroprotective treatment in this patients group.References:[1]Hak AE et al.

- OBJECTIVE: SLE is known to have an aggressive phenotype in black populations, but data from African cohorts are largely lacking. We therefore compared immunological and clinical profiles between Sudanese and Swedish patients using similar tools.METHODS: Consecutive SLE patients from Sudan (n = 115) and Sweden (n = 340) and from 106 Sudanese and 318 Swedish age- and sex-matched controls were included. All patients fulfilled the 1982 ACR classification criteria for SLE. Ten ANA-associated specificities and C1q-binding immune complexes (CICs) were measured. Cut-offs were established based on Sudanese and Swedish controls, respectively. Disease activity was measured with a modified SLEDAI and organ damage with the SLICC Damage Index. In a nested case-control design, Swedish and Sudanese patients were matched for age and disease duration.RESULTS: Females constituted 95.6% and 88.1% of Sudanese and Swedish patients, respectively (P = 0.02), with younger age at inclusion (33 vs 47.7 years; P < 0.0001) and shorter disease duration (5 vs 14 years; P < 0.0001) among Sudanese patients. Anti-Sm antibodies were more frequent in Sudanese patients, whereas anti-dsDNA, anti-histone and CICs were higher in Swedish patients. In the matched analyses, there was a trend for higher SLEDAI among Swedes. However, Sudanese patients had more damage, solely attributed to high frequencies of cranial/peripheral neuropathy and diabetes.CONCLUSION: While anti-Sm is more common in Sudan than in Sweden, the opposite is found for anti-dsDNA. Sudanese patients had higher damage scores, mainly because of neuropathy and diabetes. Sudanese patients were younger, with a shorter SLE duration, possibly indicating a more severe disease course with impact on survival rates.

- Patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) require immunosuppressive therapy for disease control and reduction of disease relapse and may be at risk for complications during Sars-CoV-2 (COVID-19) infection.Objectives:To analyze the consequences of COVID-19 in a large cohort of AAV patients regarding occurrence, need of hospitalization, treatment at the intensive care units (ICU), or death.Methods:Data were retrieved from March 2020 to mid-January 2021 from medical records from the AAV cohort (n=233). Patients diagnosed with granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) or eosinophilic granulomatosis with polyangiitis (EGPA) were included. Data included age, gender, diagnosis, ongoing immunosuppressive medication at onset of COVID-19 or at last follow-up in non-COVID individuals. Renal involvement (ever) and estimated glomerular filtration rate (eGFR) were included. COVID-19 was confirmed either by a positive PCR test in the upper airways or by serology. Severe COVID-19 was defined as need of non-invasive ventilation, ICU care, and/or death.Results:The cohort comprised of 172 patients with GPA, 50 with MPA and 11 with EGPA. There were 121 females (52%). During the study period, 20 patients (8.6%) were diagnosed with COVID-19. The median age at data retrieval in all patients was 68 years (21-93), in the COVID-19 group 63 (29-93) and 68.5 (21-90) years in the non-COVID patients.Fourty-three patients in all (18%) were hospitalized during the study period of which 11 (4.7%) due to COVID-19 infection. In all, 8 deaths occurred of which 3 were related to COVID-19.At data retrieval, 110 (47%) patients were on prednisolone treatment, 10/20 (50%) in the COVID-19 group and 100 (47%) in the non-COVID-19 group (p=0.5), with significantly higher doses in COVID-19 patients (p<0.001). In patients hospitalized with COVID-19, 6/11 (54.5%) were on prednisolone, median dose 5 mg/day (0-50). In the total group 112 (48%) were on disease modifying anti-rheumatic drugs (DMARD) and 64 (27.5%) on rituximab as maintenance therapy. Eight patients were on induction treatment with either cyclophosphamide or rituximab.Of the 20 COVID-19 cases, 8 had severe COVID-19. Of these, 2 were inactive without immunosuppressive treatment, 4 had stable disease with prednisolone (5-7.5 mg/day) in combination with DMARDs, and 2 were active treated with high dose prednisolone (25-50 mg/day) in combination with cyclophosphamide and rituximab (n=1) or rituximab (n=1).A higher proportion of patients had active AAV (p=0.03) in the severe COVID-19 then in the non-COVID group (10/213 patients).In the group with the severe COVID-19, 1/8 (12%) patient had rituximab as maintenance therapy, compared to 61/213 (28.6%) in the group of non-COVID-19 patients (p=0.5).Renal involvement (ever) was present in 144 patients (62%), in 6 patients (30%) with COVID- 19, from which 5 (62%) were in the group of severe COVID-19 patients. Median eGFR did not differ between severe COVID-19 and remaining patients with renal involvement independently of COVID-19 infection.Conclusion:We found a high rate of severe COVID-19 infection in our cohort of AAV patients which indicates risk for serious complications, especially in patients with active disease and intense immunosuppressive therapy. Maintenance therapy with rituximab did not seem to increase the risk for severe COVID-19. The findings stress the need for continued shielding and early vaccination in AAV patients.Disclosure of Interests:None declared

- Pregnant women with systematic lupus erythematosus (SLE) have an increased risk of obstetric complications, such as preeclampsia and premature births. Previous studies have suggested that renal involvement could further increase the risk for adverse obstetric outcomes. Aims: The aim of this study was to compare the obstetric outcomes in a Swedish cohort of patients with SLE with and without lupus nephritis (LN). Patients and methods The study was conducted as a retrospective observational study on 103 women with SLE, who gave birth at the Karolinska University Hospital between the years 2000-2017. Thirty-five women had previous or active LN and 68 women had non-renal lupus. Data was collected from digital medical records. The outcomes that were analysed included infants born small for gestational age (SGA), premature birth, preeclampsia, SLE- or nephritis flare and caesarean section. Results Women with LN, both with previous and with renal flare during pregnancy suffered from pre-eclampsia more often compared to women with non-renal lupus (25.7% vs 2.9%, p = 0.001) and this complication was associated with premature birth (p = 0.021) and caesarean section (p = 0.035). Conclusions Lupus nephritis is a significant risk factor for adverse obstetric outcomes in women with SLE, including preeclampsia. Those patients could benefit from more frequent antenatal controls and more vigorous follow-up.

THE NEED FOR INFORMATION AMONG PATIENTS WITH ANCA ASSOCIATED VASCULITIS DIFFERS BETWEEN GROUPS
- 2021
-
Ingår i: Annals of the Rheumatic Diseases. - : BMJ Publishing Group Ltd. - 0003-4967 .- 1468-2060. ; 80:Suppl. 1, s. 1023-1023

- Being diagnosed with ANCA associated vasculitis (AAV) can be a frightening experience and means facing changes that involves adapting to new situations1. Patients that are provided adequate information are better equipped to make well informed decisions regarding their care and stay compliant to the treatment plan. In order to provide adequate patient-centered information at the appropriate time and to identify those who may need extra support, the information needs must be explored2. There have been several studies on the information needs of rheumatological patients, although very few studies for patients with AAV.Objectives:The aim of this study was to explore what information patients with AAV need from their rheumatological team and how it differs between groups (gender, disease duration).Methods:Men and women over 18 years were included through a consecutive sample from a Rheumatology or Nephrology Clinic at Karolinska University Hospital in Sweden during 2008-2019. Patients with all forms of AAV (GPA, MPA and EGPA), that had the Rheumatology clinic as primary contact, were included.The participants were given Educational Needs Assessment Tool (ENAT) that measures the patient’s information needs3. The initial question, ‘Do you need information right now about something that can help you with your rheumatic disease?’ is answered yes/no. ENAT then includes 7 domains (Managing pain, Movement, Feelings, Disease process, Treatments, Self-help measures and Support systems) each containing 4-7 items (4-point Likert scale, ’not at all important = 0’ to ‘extremely important = 3’). The total sum is divided by the maximum score and gives the percentage response of maximum score (0-100%), 0% meaning no information need and 100% highest information need. The responses are presented as “mean % of the domain score”. Independent-sample t-test was used to compare the mean between groups. One way ANOVA was used to compare the mean domain score between the different diagnoses and age groups.Results:178 individuals completed the questionnaire, equally divided by gender. Age ranged from 18-85, median 61. 33,7% had been diagnosed within 2 years.The mean total score was 56,8 % of the highest possible score (0-100%). The highest information need was found in the domains ‘Disease process’ (78,1%), ‘Self-help measures’ (68,5%) and ‘Treatments’ (63,6%) whereas lesser need for information was found in the domains ‘Managing pain’ (47,5%), ‘Support systems’ (46,5%) and ‘Movement’ (41,1%). The domain ‘Feelings’ was scored as moderate (55,5%).Those who acknowledge a present information need also scored significantly higher overall in all the domains. Disease duration and gender showed significantly affect the information need. Highest scores were found among women with a disease duration < 2 years with significant difference in 3/7 domains. Age, disease activity, diagnosis and social status did not affect the ENAT scores.Conclusion:Even though only 38% of participants stated a current need for information, the results indicate that there are certain areas that patients with AAV consider important to receive more information about. Special consideration needs to be taken to women with short disease duration since they were shown to have a significantly higher need for information.References:[1]Mooney, J., et al.

- Immunotherapy has revolutionized cancer treatment during the last years. Several monoclonal antibodies that are specific for regulatory checkpoint molecules, that is, immune checkpoint inhibitors (ICIs), have been approved and are currently in use for various types of cancer in different lines of treatment. Cancer immunotherapy aims for enhancing the immune response against cancer cells. Despite their high efficacy, ICIs are associated to a new spectrum of adverse events of autoimmune origin, often referred to as immune-related adverse events (irAEs), which limit the utility of these drugs. These irAEs are quite common and can affect almost every organ. The grade of toxicity varies from very mild to life-threatening. The pathophysiological mechanisms behind these events are not fully understood. In this review, we will summarize current evidence specifically regarding the rheumatic irAEs and we will focus on current and future treatment strategies. Treatment guidelines largely support the use of glucocorticoids as first-line therapy, when symptomatic therapy is not efficient, and for more persistent and/or moderate/severe degree of inflammation. Targeted therapies are higher up in the treatment pyramid, after inadequate response to glucocorticoids and conventional, broad immunosuppressive agents, and for severe forms of irAEs. However, preclinical data provide evidence that raise concerns regarding the potential risk of impaired antitumoral effect. This potential risk of glucocorticoids, together with the high efficacy and potential synergistic effect of newer, targeted immunomodulation, such as tumor necrosis factor and interleukin-6 blockade, could support a paradigm shift, where more targeted treatments are considered earlier in the treatment sequence.
