Contemporary Outcomes and Predictors of Inpatient Mortality for Infective Endocarditis Occurring in Renal Transplant Recipients in the United States

Outcomes and Predictors of Inpatient Mortality for Marantic Endocarditis Complicating Systemic Lupus Erythematosus: Contemporary Nationwide Study From the United States

Systemic lupus erythematosus (SLE) patients are susceptible to marantic endocarditis (ME) due to a hypercoagulable state. The literature regarding the epidemiology and outcomes of ME in SLE patients is limited. All patients ≥18 years who had SLE with and without ME between 2007 and 2019 were identified from the National Inpatient Sample in the United States (US). Predictors of inpatient mortality for SLE patients with ME were analyzed. Between 2007 and 2019, there were 508,818 hospitalizations for SLE, of which 785 (0.2%) had ME. Of SLE patients with ME, 33 (4.2%) died while hospitalized over the study period. On multivariate analysis, female sex (adjusted odds ratio (aOR), 95% confidence intervals: 24.72 (3.21, 190.27)), age <34 years (aOR: 6.81 (1.80, 25.79)), anemia (aOR: 3.41 (1.12, 10.40)), antiphospholipid syndrome (aOR: 13.50 (3.83, 47.64)), stroke complicating ME (aOR: 9.64 (3.24, 28.71)), and acute kidney injury (aOR: 3.74 (1.06, 13.20)) were all associated with increased inpatient mortality among SLE patients with ME (P < .05 for all). Between 2007 to 2019, ME occurred in 0.2% of SLE hospitalizations, with a 4.2% average inpatient mortality over the study period. Female sex, antiphospholipid syndrome, and stroke were most strongly associated with increased inpatient mortality.

Prevalence, Characteristics, and Outcomes of Infective Endocarditis Readmissions in Patients With Variables Associated With Liver Disease in the United States

Infective endocarditis (IE) is common in patients with liver disease. Outcomes of IE in patients with liver disease are limited. We aimed to investigate IE outcomes in patients with variables associated with liver disease in the USA. We used the 2017 National Readmission Database to identify index admission of adults with IE, based on the International Classification of Disease, 10th revision codes. The primary outcome was 30-day readmission. Secondary outcomes were mortality and predictors of hospital readmission. We identified 40,413 IE admissions. Patients who were readmitted were more likely to have a history of HCV (19.4 vs 12.3%, P < .001), hyponatremia (25 vs 21%, P < .001), and thrombocytopenia (20.3 vs 16.3%, P < .001). After adjusting for age, hypertension, heart failure, diabetes mellitus, and end stage renal disease, hyponatremia (odds ratio (OR) 1.25; 95% confidence intervals [CI]: 1.17-1.35; P < .001) and thrombocytopenia (OR 1.16; 95% CI: 1.08-1.24; P < .001) correlated with higher odds of 30-day readmission. Mortality was higher among patients with hyponatremia (29 vs 22%, P < .001), thrombocytopenia (29 vs 17%, P < .001), coagulopathy (12 vs 5%, P < .001), cirrhosis (6 vs 4%, P < .001), ascites (7 vs 3%, P < .001), liver failure (18 vs 3%, P < .001), and portal hypertension (3 vs 1.5%, P < .001).
