The association between psoriatic arthritis and venous thromboembolism: a population-based cohort study

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.

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.

Cox Proportional Hazard Regression

The aim of the study is to evaluate the risk of heart disease in individuals who underwent cholecystectomy. This was a retrospective cohort study using the National Health Insurance Service database of South Korea. A total of 146,928 patients who underwent cholecystectomy and 268,502 age- and sex-matched controls were compared. Multivariate Cox proportional hazard regression analysis was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for heart disease after cholecystectomy. In results, a previous history of cholecystectomy increased the risk of heart disease (congestive heart failure [CHF], myocardial infarction [MI], atrial fibrillation [AF]) (adjusted HR [aHR]: 1.40, 95% CI: [1.36–1.44]). The increased risk was particularly seen for CHF (1.22 [1.16–1.29]) but not for MI and AF (p > 0.05). In the subgroup analyses, cholecystectomy was associated with an increased risk of MI in patients aged <65 years (1.49 [1.16–1.92] and 1.18 [1.05–1.35] in patients aged 40–49 and 50–64 years, respectively), but not in those aged ≥ 65 years (0.932 [0.838–1.037]). Moreover, the risk of MI was increased in patients without diabetes mellitus (DM) (1.16 [1.06–1.27]); however, it was decreased in patients with DM (0.83 [0.72–0.97]). In contrast, cholecystectomy did not modify the risk of AF in the subgroup analyses (all p > 0.05). In conclusion, a history of cholecystectomy is associated with an increased risk of CHF. Cholecystectomy may increase the risk of MI in the younger population without DM. These findings suggest that the alteration of bile metabolism and homeostasis might be potentially associated with the development of some heart diseases.

Abstract Background Bodyweight fluctuation is a risk factor for cardiovascular events and death. We investigated whether bodyweight variability is also a risk factor for atrial fibrillation (AF) development. Methods A nationwide population-based cohort of 8,091,401 adults from the Korean National Health Insurance Service database without previous history of AF and with at least 3 measurements of bodyweight over a 5-year period was followed up for incident AF. Intra-individual bodyweight variability was calculated using variability independent of mean, and high bodyweight variability was defined as the quartile with highest bodyweight variability (Q4) with Q1–3 as reference. Results During median 8.1 years of follow-up, AF was newly diagnosed in 158,347 (2.0%). Increasing bodyweight variability was associated with AF development after adjustment for baseline bodyweight, height, age, sex, lifestyle factors and comorbidities: each increase of 1-SD in bodyweight variability was associated with 5% increased risk of AF development (hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.04–1.05), and subjects with highest bodyweight variability (Q4) showed 14% increased risk of AF development compared to those in the quartile with lowest bodyweight variability (HR 1.14, 95% CI 1.12–1.15). When the cohort was grouped by body mass index (BMI) into underweight, normal weight, overweight, obese (Figure 1A), subjects with high bodyweight variability showed a shallow U-shaped relationship of BMI with AF incidence, with the highest incidence rate of AF in the underweight group. On the other hand, subjects with reference bodyweight variability showed a proportional increase of AF incidence with BMI, with the highest AF incidence in the obese group. High bodyweight variability was significantly associated with AF development in all BMI groups except in the very obese (BMI≥30) in multivariable analysis, and this association was stronger in subjects with lower bodyweight. In underweight subjects, high bodyweight variability was associated with 16% increased risk of AF development (HR 1.16, 95% CI 1.08–1.24). Obese subjects with high bodyweight variability compared to those with reference variability showed lower crude AF incidence rates, but after multivariable analysis, AF risk was increased (obese stage I) or comparable (obese stage II). When the cohort was grouped by total bodyweight change (Figure 1B), subjects with high bodyweight variability showed higher AF incidence and elevated AF risk on multivariable analysis in all weight change groups. Subjects with overall weight loss (≥-5%) and high bodyweight variability showed the highest AF incidence and AF risk (HR 1.12, 95% CI 1.09–1.15). Figure 1 Conclusions Fluctuation in bodyweight was independently associated with higher risk of AF development. The association of high bodyweight variability with AF development was especially stronger in subjects with lower bodyweight, and in subjects with overall weight loss (≥-5%)

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: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.

Antidepressant Use

Introduction: SSRIs, the most commonly prescribed antidepressants (AD) in the US, are linked to an increased intracerebral hemorrhage (ICH) risk possibly related to impaired platelet function. In the Florida Stroke Registry (FSR), we studied the proportion of cases presenting with ICH amongst AD users and the rate of SSRI prescription amongst stroke patients discharged on AD. Methods: From Jan 2010 to Dec 2019 we included 127,915 cases from FSR in whom information on AD use was available. Multivariable logistic regression was used to evaluate ICH proportions amongst AD and non-AD users and rates of prescribed SSRIs at discharge. Results: The rate of ICH amongst prior AD users (n=17,009, median age 74, IQR=19) and non-AD users (n=110,906, median age 72, IQR=21) were 11% and 14% respectively. Prior AD users were more likely to be female (17% vs. 10% male), non-Hispanic White (16% vs. 8% non-Hispanic Black vs. 12% Florida Hispanic vs. 6% Puerto Rican Hispanic), have hypertension (HTN) (14.% vs. 10%), diabetes mellitus (DM) (16% vs.12%), use oral anticoagulants (OAC) (17 % vs. 13%), antiplatelets (AP; 17% vs. 11%), and statins (17% vs. 10%) prior to hospital presentation. In multivariable analysis adjusting for age, race, prior history of HTN, DM, prior OAC, AP and statin use, AD users just as likely to present with spontaneous ICH as compared to non-AD users (OR=0.92, 95% CI 0.85, 1.01). A total of 3.4% of all ICH patients and 9% of those in whom AD information was available were discharged home on an AD (74 % SSRI, 24% other AD). Conclusion: In this large population-based study, we did not find an association between prior AD use and an increased rate of ICH. Importantly AD (mostly SSRIs) are commonly prescribed to patients with ICH in routine clinical practice. The association between types, duration, and safety of antidepressant use in ICH patients deserves further studies.

Background: Previous studies showed conflicting results regarding the mortality risk in psoriasis patients with respect to disease severity and presence of psoriatic arthritis. This study aimed to determine the mortality risk in patients with mild and severe psoriasis and patients with psoriatic arthritis (PsA). Methods: A nationwide population-based cohort study was conducted based on data from the Taiwan National Health Insurance Research Database between 2002 and 2012. Incident psoriasis subjects were classified into two groups: psoriasis without arthritis and psoriasis with arthritis. Patients who had received systemic therapy and/or phototherapy were classified as having severe psoriasis; otherwise, patients were classified as having mild psoriasis. Control subjects without psoriasis were selected to match each psoriasis patient from the database within the same observational period. Cox proportional hazards analysis was used to compare the hazard ratio (HR) of time to death. Results: A total of 106,701 patients with psoriasis were included in this study. After controlling for demographics and comorbidities, psoriasis patients had a higher mortality risk compared with the control group (HR 1.41; 95% confidence interval (CI) 1.36 to 1.46). Compared with psoriasis alone, the mortality risk was not increased for PsA (HR = 1.01; 95% CI 0.93 to 1.10). Besides, severe psoriasis did not increase mortality risk compared with mild psoriasis (HR = 1.0; 95% CI 0.95 to 1.06). Conclusions: Patients with psoriasis had a higher mortality risk compared with control subjects, whereas psoriasis severity and presence of PsA had no impact on mortality risk in psoriasis patients.

Abstract Adults with sleep problems are at higher risk for onset of musculoskeletal pain, but the evidence is less clear for children. This prospective cohort study investigated whether children with sleep problems are at higher risk for onset of musculoskeletal pain and explored whether sex is a modifier of this association. In a prospective cohort study of Australian schoolchildren (n = 1239, mean age 9 years), the associations between sleep problems at baseline and new onset of both musculoskeletal pain and persistent musculoskeletal pain (pain lasting > 3 months) 1 year later were investigated using logistic regression. The potential modifying effect of sex was also assessed. One-year incidence proportion for musculoskeletal pain onset is 43% and 7% for persistent musculoskeletal pain. Sleep problems were associated with musculoskeletal pain onset and persistent musculoskeletal pain onset in boys, odds ratio 2.80 (95% CI 1.39, 5.62) and OR 3.70 (1.30, 10.54), respectively, but not girls OR 0.58 (0.28, 1.19) and OR 1.43 (0.41, 4.95), respectively. Conclusions: Rates of musculoskeletal pain are high in children. Boys with sleep problems are at greater risk of onset of musculoskeletal pain, but girls do not appear to have higher risk. Consideration of sleep health may help prevent persistent musculoskeletal pain in children. What is Known:• Sleep problems are associated with the onset of musculoskeletal pain in adults.• It is not clear if the association between sleep problems and the onset of musculoskeletal pain is present also in children and if sex plays a role in this association. What is New:• This is the first large population-based study that has prospectively investigated the relationship between sleep problems and onset of musculoskeletal pain in school-aged children.• Children, especially boys with sleep problems, were at increased risk for the development of persistent musculoskeletal pain.

AbstractStudies evaluating the relationship between platelet indices and cardiovascular (CV) outcomes yielded conflicting results. We assessed the incidence of adverse events according to baseline quintiles of platelet indices in the prospective cohort of the Malmö Diet and Cancer Study. A total of 30,314 individuals (age 57 ± 8 years) were followed for a median of 16 years (468,490 person-years). Outcome measures included all-cause death, CV death, myocardial infarction (MI), and ischemic stroke. The fifth quintile of platelet count (> 274.6 × 109/L) was associated with higher incidence of all-cause death (hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.09–1.32, p < 0.001), CV death (HR 1.19, 95% CI 1.00–1.42; p = 0.044), MI (HR 1.32, 95% CI 1.12–1.54; p = 0.001), and ischemic stroke (HR 1.27, 95% CI 1.08–1.50, p = 0.004) compared with the first quintile (≤ 185 × 109/L), and also associated with a lower survival, regardless of previous history of MI (p for interaction = 0.58) or stroke (p for interaction = 0.42). In the highest quintile, history of stroke had a higher risk of CV death (HR 3.18, 95% CI 1.54–6.54) compared with no previous stroke (HR 1.12, 95% CI 0.96–1.31). The risk of MI and stroke was greatest in the fifth quintile, regardless of previous MI or previous stroke, respectively. The risk of all adverse events was similar across different quintiles of mean platelet volume. In conclusion, elevated platelet count is associated with higher mortality and risk of CV events, regardless of previous MI and stroke. Platelet count may thus be a useful marker for further stratification of CV risk, and especially of death.

Abstract STUDY QUESTION Is polycystic ovarian syndrome (PCOS) in women associated with the increasing incidence of depression in an East Asian population? SUMMARY ANSWER Younger PCOS patients (aged 15–29 years), but not middle-aged patients, have an increased risk of depression in Taiwan. WHAT IS KNOWN ALREADY During reproductive age, 6–10% of women have PCOS. Among them, ~40% experience depression, mostly at young ages. STUDY DESIGN, SIZE, DURATION This is a retrospective population-based cohort study analysing depression risk in Taiwanese women using data from a nationwide database containing 1998–2013 data of nearly 1 million people. PARTICIPANTS/MATERIALS, SETTING, METHODS We included 15- to 50-year-old women newly diagnosed with PCOS during 1998–2013 from the Taiwan National Health Insurance Research Database as the PCOS cohort (n = 7684) and then randomly matched them 4 : 1 by sex, age and index year with women without PCOS as the comparison cohort (n = 30 736). We used multivariable Cox proportional hazard regression analysis to determine the association between PCOS and depression risk [hazard ratio (HR) with 95% confidence interval (CI)]. MAIN RESULTS AND THE ROLE OF CHANCE The incidence of depression was higher in the PCOS group than in the comparison group (6.67 vs. 4.82 per 1000 person-years; adjusted HR = 1.28, 95% CI = 1.12–1.46). PCOS patients aged 15–29 years had a significantly higher depression risk (adjusted HR = 1.39, 95% CI = 1.18–1.65); no such significant association was noted among patients aged 30–39 years and 40–50 years. LIMITATIONS, REASONS FOR CAUTION A history of malignancy, which may increase depression, could not be obtained for our study patients. Moreover, we could not obtain a family history of depression, a relevant risk factor for depression. Finally, the database has no records of body mass index, which may influence depression outcome. WIDER IMPLICATIONS OF THE FINDINGS In Taiwan, younger PCOS patients (15–29 years), but not the middle-aged patients, have an increased risk of depression. Our findings provide vital information to patients, clinicians, the Taiwan Government and other developing Asian countries to improve the PCOS treatment strategies in the future. Routine screening for depression in PCOS patients may be implemented into the health practice.
