AbstractThe association between bullous pemphigoid (BP) and melanoma is yet to be investigated. We aimed to assess assess the bidirectional association between BP and melanoma and to delineate the epidemiological features of patients with both diagnoses. A population-based cohort study was performed comparing BP patients (n = 3924) with age-, sex- and ethnicity-matched control subjects (n = 19,280) with regard to incident cases of melanoma. A case–control design was additionally adopted to estimate the risk of BP in individuals with a preexisting diagnosis of melanoma. The prevalence of preexisting melanoma was higher in patients with BP than in control subjects (1.5% vs. 1.0%, respectively; P = 0.004). A history of melanoma confers a 50% increase in the risk of subsequent BP (OR 1.53; 95% CI 1.14–2.06). This risk was higher among males (OR 1.66; 95% CI 1.09–2.54) and individuals older than 80 years (OR 1.63; 95% CI 1.11–2.38), and persisted after adjustment for multiple putative confounders including PD-1/PDL-1 antagonists (adjusted OR 1.53; 95% CI 1.14–2.06). Conversely, the risk of melanoma among patients with BP was slightly elevated, but did not reach the level of statistical significance (adjusted HR 1.13; 95% CI 0.73–1.74). Patients with a dual diagnosis of BP and melanoma were older at the onset of BP and had lower body mass index. A history of melanoma is associated with a 50% increase in the incidence of subsequent BP. Physicians managing patients with both conditions should be aware of this association. Further research is warranted to reveal the underlying mechanism of these findings.

Background: Bullous pemphigoid (BP) and asthma both share a pathogenic role of eosinophils and immunoglobulin E (IgE) and favorable response for corticosteroids and omalizumab. However, the association between these conditions is yet to be investigated. We sought to estimate the risk of having BP among patients previously diagnosed with asthma and to characterize patients with coexistent BP and asthma. Methods: Utilizing the dataset of Clalit Health Services, a population-based case-control study was conducted comparing BP patients (n = 3,924) with age-, sex-, and ethnicity-matched control subjects (n = 19,280) regarding the presence of asthma. Logistic regression models were utilized for univariate and multivariate analyses. Results: The prevalence of preceding asthma was higher in patients with BP than in control subjects (11.1 vs. 7.9%, respectively; p < 0.001). A history of asthma was associated with a 50% increase in the risk of BP (OR 1.45; 95% CI 1.30–1.62). The association was not altered greatly after adjusting for demographics (adjusted OR 1.43; 95% CI 1.28–1.61) as well as for demographics and comorbidities (adjusted OR 1.40; 95% CI 1.25–1.57). The average (SD) latency between the diagnosis of asthma and the development of BP was 12.5 (14.7) years. When compared with other patients with BP, those with a dual diagnosis of BP and asthma were older, had higher BMI, and were more frequently managed by corticosteroids and immunosuppressive and immunomodulatory adjuvants. Conclusions: Asthma confers a predisposition to the development of BP. Awareness of this association may be of help for physicians managing patients with BP and asthma. Further research is required to elucidate the mechanism underlying this observation.

Purpose Patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) often present with infections, but there are little data to assess whether a personal history of selected infections may act as pathogenic triggers. To additionally expand our knowledge on the role of immune stimulation in the causation of AML and MDS, we have conducted a large, population-based study to evaluate the risk of AML and MDS associated with a prior history of a broad range of infections or autoimmune diseases. Patients and Methods By using population-based central registries in Sweden, we included 9,219 patients with AML, 1,662 patients with MDS, and 42,878 matched controls. We used logistic regression to calculate odds ratios (ORs) and 95% CIs for the association of AML or MDS with infectious and/or autoimmune diseases. Results Overall, a history of any infectious disease was associated with a significantly increased risk of both AML (OR, 1.3; 95% CI, 1.2 to 1.4) and MDS (OR, 1.3; 95% CI, 1.1 to 1.5). These associations were significant even when we limited infections to those occurring 3 or more years before AML/MDS. A previous history of any autoimmune disease was associated with a 1.7-fold (95% CI, 1.5 to 1.9) increased risk for AML and 2.1-fold (95% CI, 1.7 to 2.6) increased risk for MDS. A large range of conditions were each significantly associated with AML and MDS. Conclusion Our novel findings indicate that chronic immune stimulation acts as a trigger for AML/MDS development. The underlying mechanisms may also be due to a common genetic predisposition or an effect of treatment for infections/autoimmune conditions.

Abstract The associations between immune-related conditions and multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) have previously been investigated with inconsistent results. In a large population-based study, we identified 19 112 patients with MM, 5403 patients with MGUS, 96 617 matched control subjects, and 262 931 first-degree relatives. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for the association of MM and MGUS with immune-related conditions by use of logistic regression. A personal history of all infections combined was associated with a significantly increased risk of MM (OR = 1.2; 95% CI, 1.1-1.3), and a personal history of all conditions in the categories infections (OR = 1.6; 95% CI, 1.5-1.7), inflammatory conditions (OR = 1.4; 95% CI, 1.2-1.5), and autoimmune diseases (OR = 2.1; 95% CI, 1.9-2.4) was associated with a significantly increased risk of MGUS. Several specific immune-related conditions elevated the risk of MM and/or MGUS. A family history of autoimmune disease was associated with a significantly increased risk of MGUS (OR = 1.1; 95% CI, 1.00-1.2), but not MM. Our findings suggest that immune-related conditions and/or their treatment are of importance in the etiology of MGUS and possibly MM. The association of both personal and family history of autoimmune disease with MGUS indicates the potential for shared susceptibility for these conditions.

Aim Migraine, in particular with aura, has been associated with an increased risk for ischemic stroke and coronary heart disease. The underlying mechanism is unknown. In a cross-sectional case control study we investigated whether an enhanced risk of atherosclerosis in migraineurs explains this increased cardiovascular risk. Methods Subjects were participants from the population-based Erasmus Rucphen Family study. Atherosclerosis was assessed in 360 migraineurs (209 without aura and 151 with aura) and 617 subjects without migraine or severe headache. Atherosclerosis was quantified by intima media thickness, pulse wave velocity and ankle-brachial index. Results Migraineurs, especially with aura, were found more likely to smoke, have diabetes or a modestly decreased HDL-cholesterol. No differences were found for the atherosclerosis parameters. Conclusion In this large population-based study, migraineurs have no increased risk of atherosclerosis. Therefore, enhanced atherosclerosis is an unlikely explanation for the increased cardiovascular risk seen in migraineurs.

Abstract Introduction: Certain autoimmune and infectious conditions are associated with increased risks of subtypes of non-Hodgkin lymphomas (NHL). A few prior studies suggest that chronic immune stimulation may particularly elevate risk for the NHL subtype lymphoplasmacytic lymphoma (LPL)/Waldenström’s macroglobulinemia (WM). To improve our understanding on the role of immune-related and inflammatory conditions in LPL/WM pathogenesis, we conducted a large population-based study including close to 2,500 LPL/WM patients diagnosed in Sweden and almost 10,000 matched controls. Methods: Using both the central Cancer registry and local hospital-based registries, we identified all LPL/WM patients diagnosed in Swedish hospitals 1958–2005. From the Swedish Population Registry we identified four matched controls per LPL/WM patient. Through data linkage with the central Inpatient registry, we gathered information on hospital inpatient discharges that listed autoimmune-, infectious-, and other inflammatory/allergic diseases present at least 1 year prior to LPL/WM. Using Poisson regression, we calculated rate ratios (RR) and 95% confidence intervals (CI) adjusted for categorical year of birth, date of diagnosis, gender, and county. Results: A total of 2,470 LPL/WM patients (647 LPL and 1,823 WM), and 9,698 population-based matched controls were included in the study. We found an increased risk of developing LPL/WM among individuals with a prior history of systemic sclerosis (RR=4.7; 1.4–15.3), Sjögren’s syndrome (RR=12.1; 3.3–45.0), autoimmune hemolytic anemia (AIHA) (RR=24.2; 5.4–108.2), polymyalgia rheumatica (RR=2.9; 1.6–5.2), and temporalis arteritis (RR=8.3; 2.1–33.1). We also found excess risk of LPL/WM among persons with a history of pneumonia (RR=1.4; 1.1–1.7), septicaemia (RR=2.4; 1.2–4.3), pyelonephritis (RR=1.7; 1.1–2.5), sinusitis (RR=2.7; 1.4–4.9), herpes zoster (RR=3.4; 2.0–5.6), and influenza (RR=2.9; 1.7–5.0). Importantly, when we assessed the associations by latency (time between immune-related or inflammatory conditions and LPL/WM), for most autoimmune- and infectious diseases the excess LPL/WM risk remained significant at >5 years latency. We found no significant increased risk for LPL/WM among individuals with prior chronic inflammatory or allergic conditions. Conclusions: In the largest investigation of risk factors for LPL/WM to date, we found a personal history of certain autoimmune and infectious diseases to be associated with excess LPL/WM risk. Immune-related conditions might act as potential LPL/WM triggers or they could represent premalignant immune disruptions preceding LPL/WM. Our results provide novel insights into the as yet unclear pathogenesis of LPL/WM.

Abstract Background Although the risk of cardiovascular disease has been discussed extensively in both psoriasis (PsO) and psoriatic arthritis (PsA), very few studies have addressed the occurrence of venous thromboembolic (VTE) events among PsO patients, and even fewer in PsA. Thus, our goal was to assess the association between PsA and VTE events using a large population-based database. Methods This retrospective cohort study includes all 5,275 patients with newly diagnosed PsA from the largest health care provider in Israel between January 2003 and December 2018. Identified PsA patients were matched by age, sex, ethnicity, and index date with 21,011 controls without PsA from the same database. Both groups were followed through June 30, 2019 for the occurrence of VTE event. Cox proportional hazard regression models were used to assess the association between PsA and VTE. Results PsA cohort consisted of 53.2% females with mean age of 51.7±15.4 Sixty-two patients (1.2%) were diagnosed with VTE in the PsA group and 176 patients (0.8%) in the control group (p=0.023, HR=1.40, 95% CI 1.05-1.87). However, there was no increased risk of VTE among PsA patients on multivariable analysis (p=0.16, HR=1.27, 95% CI 0.91-1.80). Within the PsA group, patients with VTE were more often of older age and with history of VTE. Conclusions This study suggests that the increased risk of VTE in PsA patients appears to be related to the underlying comorbidities and not independently associated with PsA. Age and previous history of VTE were the only risk factors associated with increased risk of VTE in patients with PsA. Addressing VTE risk is recommended especially in the era of Janus kinase inhibitors.

Abstract Abstract 3987 Background: Patients with multiple myeloma are at an increased risk of venous thromboembolism (VTE), especially when treated with thalidomide and lenalidomide. The etiology of this is largely unknown, but probably involves both genetic and environmental factors. Family history of VTE is a known risk factor for VTE in the general population, including known inherited thrombophilic abnormalities. The influence of a family history of VTE as a potential risk factor for VTE in multiple myeloma patients is unknown. To expand our knowledge on this topic, we conducted a large population-based study based on all multiple myeloma patients diagnosed in Sweden 1958–2004. Patients and Methods: We assessed the impact of family history of VTE as a risk factor for VTE among 21,067 multiple myeloma patients and 83,094 matched controls. Data on multiple myeloma patients was gathered from the Swedish Cancer Registry, information on first-degree relatives from the national Multigenerational Registry, and occurrence of VTE from the nationwide Patient Registry. We calculated odds ratios (OR) and 95% confidence intervals (CI) using chi-square. Results: Of the 21,067 multiple myeloma patients included in the study (54% males, median age at diagnosis 71 years), 66% had an identifiable first-degree relative. VTE was diagnosed in 1,429 multiple myeloma patients, and 921 had a family history of VTE. Compared to multiple myeloma patients without a family history of VTE, multiple myeloma patients with a family history of VTE had a 2.2-fold (95% CI 1.8–2.7; p<0.001) higher risk of VTE. Among 4,986 controls that were diagnosed with VTE, 316 had a family history of VTE. Controls with a family history of VTE had a 1.5-fold (95% CI 1.3–1.7; p<0.001) increased risk of VTE compared to controls without a family history of VTE. The difference of the impact of family history of VTE on the risk of VTE in multiple myeloma patients versus controls was significant. Summary and Conclusions: In this large population-based study including more than 20,000 multiple myeloma patients, we found family history of VTE to have a larger impact on VTE risk in multiple myeloma than in matched controls. Our findings confirm that genetic factors contribute to thrombophilia in multiple myeloma and may have therapeutic implications regarding thromboprophylaxis and treatment.

Abstract Background and Aims An increasing number of patients are returning to dialysis after kidney allograft failure (KAF). These patients are at higher risk of complications and mortality compared with incident ESKD patients.. In the pediatric population these data are missing and outcomes have never been investigated before in a nationally representative sample. The aim of this study was to describe the characteristics and hard outcomes of children entering dialysis after KAF in a large population of pediatric dialysis patients. Method We retrospectively reviewed the files of patients receiving chronic dialysis at &lt;18 years, recorded from January 1990 to June 2019 by the Italian Registry of Pediatric Chronic Dialysis (IRPCD), a nationwide population-based chronic dialysis network involving all 12 Italian pediatric dialysis centers. We identified 126 patients who had returned to dialysis after KAF. All patients were followed from (re)initiation of dialysis until death, re-transplantation or loss to follow-up. Multivariable regression and survival analysis were used to evaluate factors involved in the choice of dialysis modality and patient outcomes. Results After KAF, 45 (35.7 %) patients were treated with PD and 81 (64,3%) with HD. Prior to kidney transplantation (Ktx), 74 (58.7%) were on PD, 45 (35.7%) on HD, and 7 on conservative care (5.5%). Compared with PD patients, those on HD were older (median age of 14.8 years [IQR 11.4-17.5] vs. 10.8 [IQR 2-6.5] vs.; p=0.002), had a longer transplant vintage ([55.2 months [13.2-100.3]) vs. 33 [5.1-82.2], and reentered dialysis in more recent calendar years (2013 [2007-2017] vs. 2004 [2001-2009]). Significant predictors for being treated with PD after KAF were a younger age at dialysis start (OR 0.83 per year increase [95%CI 0.72-0.94]) and a history of PD use before Ktx (OR 12.74 [2.2-74.6]). Patients returning to dialysis in more recent eras (OR 0.87 per year increase [0.81-0.94]) and those who were treated with more than one dialysis modality before Ktx (OR 0.15 for being treated with PD [0.04-0.63]) were more likely to be initiated on HD. Over the observation period, 6 PD (13.6%) and 3 HD (4.2%) patients died. After adjustment for several covariates, patients on PD exhibited an increased risk for mortality compared with HD (HR 4.65 [1.12-19.30], while the difference for modality failure and access to renal transplantation did not reach statistical significance (Fig.1) Conclusion Patients returning to dialysis after KAF in more recent years are more likely to be initiated on HD rather than PD. According to our registry data, the use of PD is associated with a lower survival among patients initiating dialysis after KAF.

Abstract Aims Pulse pressure (PP) is a well-known risk factor for cardiovascular disease. However, the association between the PP and dementia is not well identified. This study aimed to determine the effect of PP on the risk of dementia development in different age subgroups using a longitudinal, population-based, and stroke-free cohort from the general population. Methods The association of PP with the development of incident dementia was assessed from January 1, 2005, to December 31, 2013, in 433,154 participants without a history of dementia or stroke from the Korea National Health Insurance Service-Health Screening cohort. The diagnosis of dementia was defined using the 10th revision of the International Classification of Disease codes. Results The mean age of the cohort was 55.7±9.2 years, 45.7% were women. Hypertension was 23.6%. The mean systolic and diastolic blood pressure of the entire cohort were 125.9±16.6 and 78.4±10.7 mmHg, respectively. Mean PP was 47.5±10.9 mmHg. In the middle-age group (40 to 50 year-old), increasing of 10 mmHg of PP was associated with incident dementia after adjusting mean blood pressure and clinical variables with a hazard ratio (HR) of 1.21 (95% confidence interval [CI]: 1.19–1.23, p&lt;0.001). The association was still significant even after censoring for stroke (HR: 1.16, 95% CI: 1.08–1.22, p&lt;0.001). In the older population, elevation of PP was not associated with dementia development (HR: 0.98, 95% CI: 0.95–1.01, p=0.247) Conclusion PP was associated with increased risk of dementia only in middle-aged population beyond that of mean arterial pressure.

Background:Cohort studies using nationwide health registers have shown an increased risk for affective and anxiety disorders in people with ankylosing spondylitis (AS) and rheumatoid arthritis (RA) (1-3). Moreover, a nationwide cohort study demonstrated an increased risk for mental disorders in people with rheumatic diseases (4).Objectives:We aimed to investigate the risk for psychiatric hospitalization following a hospitalization for rheumatic disease.Methods:Using data from the Czech nationwide register of all-cause hospitalizations, we obtained 4 971 individuals hospitalized (index hospitalization) between 2004 and 2012 for rheumatic diseases - RA, spondyloarthritis (including AS, psoriatic arthritis and undifferentiated spondyloarthritis), systemic lupus erythematosus and systemic sclerodermia, with no history of psychiatric and rheuma-related hospitalization in the previous 10 years from the index hospitalization. On these individuals, we randomly matched (on age, gender and year of index hospitalization) controls that were hospitalized in the same time period for a non-rheumatic disease and have no history of psychiatric and rheumatic hospitalization in the last 10 years from their index hospitalization, in the ratio of 1:5. We employed conditional logistic regression for assessing the risk for psychiatric hospitalization in the subsequent 3 years from the index hospitalization. To strengthen our results, we repeated the matching step 100 times and run the analysis on each resulting dataset separately, and pooled the results. The findings are expressed as odds ratios (OR) with 95% confidence intervals (95% CI).Results:We identified an elevated risk for psychiatric (OR = 1.34, 95% CI = 1; 1.78) and for affective disorders (OR = 2.19, 95% CI = 1.17; 4.1) in people hospitalized for rheumatic diseases. We did not find a statistically significant association with organic, psychotic and anxiety disorders.Conclusion:There is an increased risk for experiencing a psychiatric disorder in the period of 3 years after a rheuma-related hospitalization.References:[1]Shen C-C, Hu L-Y, Yang AC, Kuo BI-T, Chiang Y-Y, Tsai S-J.
