Risk of subsequent ischemic and hemorrhagic stroke in patients hospitalized for immune-mediated diseases: a nationwide follow-up study from Sweden.

ABSTRACT:

Background

Certain immune-mediated diseases (IMDs) have been associated with increased risk for cardiovascular disorders. The aim of the present study was to examine whether there is an association between 32 different IMDs and first hospitalization for ischemic or hemorrhagic stroke.

Methods

All individuals in Sweden hospitalized with a main diagnosis of IMD (without previous or coexisting stroke), between January 1, 1987 and December 31, 2008 (n = 216,291), were followed for first hospitalization for ischemic or hemorrhagic stroke. The reference population was the total population of Sweden. Adjusted standardized incidence ratios (SIRs) for ischemic and hemorrhagic stroke were calculated.

Results

Totally 20 and 15 of the 32 IMDs studied, respectively, were associated with an increased risk of ischemic and hemorrhagic stroke during the follow-up. The overall risks of ischemic and hemorrhagic stroke during the first year after hospitalization for IMD were 2.02 (95% CI 1.90-2.14) and 2.65 (95% CI 2.27-3.08), respectively. The overall risk of ischemic or hemorrhagic stroke decreased over time, to 1.50 (95% CI 1.46-1.55) and 1.83 (95% CI 1.69-1.98), respectively, after 1-5 years, and 1.29 (95% CI 1.23-1.35) and 1.47 (95% CI 1.31-1.65), respectively, after 10+ years. The risk of hemorrhagic stroke was ?2 during the first year after hospitalization for seven IMDs: ankylosing spondylitis (SIR = 8.11), immune thrombocytopenic purpura (SIR = 8.60), polymyalgia rheumatica (SIR = 2.06), psoriasis (SIR = 2.88), rheumatoid arthritis (SIR = 3.27), systemic lupus erythematosus (SIR = 8.65), and Wegener's granulomatosis (SIR = 5.83). The risk of ischemic stroke was ?2 during the first year after hospitalization for twelve IMDs: Addison's disease (SIR = 2.71), Crohn's disease (SIR = 2.15), Grave's disease (SIR = 2.15), Hashimoto's thyroiditis (SIR = 2.99), immune thrombocytopenic purpura (SIR = 2.35), multiple sclerosis (SIR = 3.05), polymyositis/dermatomyositis (SIR = 3.46), rheumatic fever (SIR = 3.91), rheumatoid arthritis (SIR = 2.08), Sjögren's syndrome (SIR = 2.57), systemic lupus erythematosus (SIR = 2.21), and ulcerative colitis (SIR = 2.15).

Conclusions

Hospitalization for many IMDs is associated with increased risk of ischemic or hemorrhagic stroke. The findings suggest that several IMDs are linked to cerebrovascular disease.

Project description:BACKGROUND: Certain immune-mediated diseases (IMDs), such as rheumatoid arthritis and systemic lupus erythematosus, have been linked to cardiovascular disorders. We examined whether there is an association between 32 different IMDs and risk of subsequent hospitalization for coronary heart disease (CHD) related to coronary atherosclerosis in a nationwide follow up study in Sweden. METHODS AND FINDINGS: All individuals in Sweden hospitalized with a main diagnosis of an IMD (n = 336,479) without previous or coexisting CHD, between January 1, 1964 and December 31 2008, were followed for first hospitalization for CHD. The reference population was the total population of Sweden. Standardized incidence ratios (SIRs) for CHD were calculated. Overall risk of CHD during the first year after hospitalization for an IMD was 2.92 (95% CI 2.84-2.99). Twenty-seven of the 32 IMDs studied were associated with an increased risk of CHD during the first year after hospitalization. The overall risk of CHD decreased over time, from 1.75 after 1-5 years (95% CI 1.73-1.78), to 1.43 after 5-10 years (95% CI 1.41-1.46) and 1.28 after 10+ years (95% CI 1.26-1.30). Females generally had higher SIRs than males. The IMDs for which the SIRs of CDH were highest during the first year after hospitalization included chorea minor 6.98 (95% CI 1.32-20.65), systemic lupus erythematosus 4.94 (95% CI 4.15-5.83), rheumatic fever 4.65 (95% CI 3.53-6.01), Hashimoto's thyroiditis 4.30 (95% CI 3.87-4.75), polymyositis/dermatomyositis 3.81 (95% CI 2.62-5.35), polyarteritis nodosa 3.81 (95% CI 2.72-5.19), rheumatoid arthritis 3.72 (95% CI 3.56-3.88), systemic sclerosis 3.44 (95% CI 2.86-4.09), primary biliary cirrhosis 3.32 (95% CI 2.34-4.58), and autoimmune hemolytic anemia 3.17 (95% CI 2.16-4.47). CONCLUSIONS: Most IMDs are associated with increased risk of CHD in the first year after hospital admission. Our findings suggest that many hospitalized IMDs are tightly linked to coronary atherosclerosis.

Project description:Brain metastases can contribute to a decreased quality of life for patients with cancer, often leading to malaise, neurologic dysfunction, or death. Intracerebral hemorrhage (ICH) is an especially feared complication in patients with brain metastases given the potential for significant morbidity and mortality. We aim to characterize patients with cancer and brain metastases admitted to hospitals nationwide and identify factors associated with ICH. The 2016 Healthcare Cost and Utilization Project Nationwide Inpatient Sample (HCUP-NIS) was queried for all patients with cancer hospitalized with a diagnosis of brain metastases. Admissions with a primary or secondary diagnosis of ICH were further identified. Baseline differences in demographic, clinical, socioeconomic, and hospital-related characteristics between patients with and without ICH were assessed by chi-square, Mann-Whitney U, and ANOVA testing. Multivariable logistic regression was used to identify factors associated with ICH. Weighted frequencies were used to create national estimates for all data analysis. In 2016, a total 145,225 hospitalizations were associated with brain metastases, of which 4,145 (2.85%) had a concurrent diagnosis of ICH. Patients with ICH were more likely to have a longer length of stay (median 5 days vs 4 days, p?<?0.001) and a higher cost of stay (median $14,241.14 vs $10,472.54, p? <?0.001). ICH was found to be positively associated with having a diagnosis of melanoma (odds ratio [OR] 5.01; 95% Confidence Interval [CI] 3.50-7.61) and kidney cancer (OR 2.50; 95% CI 1.69-3.72). Patients on long-term anticoagulation had a higher risk of ICH (OR 1.49; CI 1.15-1.91). Approximately 3% of patients hospitalized with brain metastases also had a diagnosis of ICH, which was significantly associated with longer length of stay and cost. Patients with melanoma, kidney cancer, and on long-term anticoagulation had a higher risk of ICH. Physicians should consider the risks of anticoagulation carefully for patients with brain metastases, especially those with melanoma and kidney cancer.
