Chronic Toxoplasma gondii (T. gondii ) infection is known to trigger potentially adverse immuno-regulatory changes, but the long-term implication for heart transplant (HTx) recipients has not been assessed previously. Hence, we evaluated the risk of mortality, development of cardiac allograft vasculopathy (CAV) and acute cellular rejection amongst T. gondii seropositive HTx recipients and the four donor/recipient seropairing groups. Methods: Frozen pre-HTx serum samples of 288 recipients and 246 donors were evaluated for T. gondii serostatus using Platelia IgG immunoassay method. All patients had also undergone prospective serostatus evaluation using alternative assays and results determined by the two methods were compared. Follow-up data regarding mortality, CAV development and acute cellular rejection was available for all patients. Results: Overall, 211 (73%) recipients were seronegative and 77 (27%) were seropositive. In total, 82 recipients died, 76 developed CAV and 82 had significant cellular rejection. Recipient seropositivity was associated with a significantly higher risk of all-cause mortality (hazard ratio [HR], 1.9; 95% CI, 1.1–3.4; p= 0.02) and CAV mortality (HR=4.4; 95% CI, 1.3–15.6, p=0.02), but was not associated with earlier CAV development or higher rejection score. Donor/recipient seropairing status was not a risk factor for any endpoint. Conclusions: T. gondii seropositivity amongst HTx recipients is associated with a significantly increased risk of long-term total, and in particular CAV-related, mortality. This may be mediated via immunoregulatory changes triggered by chronic T. gondii infection and needs to be explored further.

Cellular Rejection

Despite the widespread use of potent immunosuppressive drugs, such as cyclosporin A and mycophenolate mofetil, ongoing and recurrent cellular rejection remain a common problem after heart transplantation. We aimed to describe the long-term effects of conversion from cyclosporine A to tacrolimus in patients with ongoing and recurrent cellular rejection. This was a single-centre retrospective analysis of 17 heart transplant recipients who were switched from cyclosporine A to tacrolimus due to ongoing (5 patients) or recurrent cellular rejection (12 patients). We studied long-term efficacy and safety of this approach. 167 endomyocardial biopsies were performed during a mean followup of 69.1±12.7 months. Thirteen biopsies (7.8 %) in eight patients (47 %) revealed higher grades of acute cellular rejection (Banff 2). However, they were not hemodynamically significant and did not require intravenous antirejection therapy. The mean rejection score was reduced significantly. Conversion to tacrolimus was tolerated in 82 % pts without any significant side effects during a long-term follow-up. In conclusion, the conversion to tacrolimus in heart transplant recipients with ongoing or recurrent acute cellular rejection was safe and effective also during a long-term follow-up.

Introduction: Higher levels of kidney-injury molecule-1 (KIM-1) measured in urine are associated with presence and progression of acute renal disease. A recent study reported similar results for KIM-1 measured in blood. Hypothesis: We hypothesized that KIM-1 measured in stored serum from middle-aged men who participated in the Multiple Risk Factor Intervention Trial (MRFIT) would differentiate very long-term risk of fatal CHD vs. survival to a mean age of 80 over approximately 30 year follow-up. Methods: We conducted a nested case-control study within MRFIT, which in 1973-76 randomized 12,866 high risk but CVD free men ages 35-57 to risk factor intervention vs. usual care. Serum samples were collected at baseline and stored for future use. The trial concluded in 1982 but long-term mortality follow-up was ascertained through 2005 using the National Death Index. From MRFIT participants with stored serum from baseline, we sampled 100 men who died of CHD (mean age 47.3 at baseline and 73.9 at death), and 100 men who survived to 2005 (mean age =48.4 at baseline and 80.1 in 2005.) KIM-1 was assayed from stored serum samples using high sensitivity single-molecule counting technology (Erenna ® Immunoassay System, Singulex), with limit of detection (LoD)=0.5 pg/ml, and lower limit of quantification (LLoQ)=2.0 pg/ml. Results were compared between cases and controls using Wilcoxon rank tests and logistic regression. Results: Inter-assay %CVs were 8%. Median KIM-1 was higher for smokers vs. non-smokers and for men with vs. without hypertension, but was not associated with high cholesterol. KIM-1 was significantly higher in cases (183 pg/ml (IQR: 137-239) versus controls, (161 pg/ml (IQR:109-212), p=0.03; OR (95%CI)for Q4 versus Q1 was 2.26 (1.02 - 5.02) Adjusted for age and smoking the OR(95%CI) of fatal CHD for Q4 vs. Q1 was 2.34 (1.02- 5.37), and further adjusted for diastolic BP and serum cholesterol at baseline, was 2.0 (95% CI: 0.8-4.7). Conclusions: Higher serum KIM-1 levels at midlife were associated with a ∼2-fold increased risk of fatal CHD vs. survival over ∼30 years of follow-up. This is the first report of a longitudinal association of circulating KIM-1 levels with fatal CHD in long-term follow-up.

SUMMARYWe evaluated magnitude of bacteraemia as a predictor of mortality, comprising all adult patients with a first-time mono-microbial bacteraemia. The number of positive bottles [1 (reference), 2, or 3] in the first positive blood culture (BC) was an index of magnitude of bacteraemia. We used Cox's regression analysis to determine age and comorbidity adjusted risk of mortality at days 0–7, 8–30, and 31–365. Of 6406 patients, 31·1% had BC index 1 (BCI 1), 18·3% BCI 2, and 50·6% BCI 3. BCI 3 patients had increased risk of mortality for days 0–7 (1·30, 95% CI 1·10–1·55) and days 8–30 (1·37, 95% CI 1·12–1·68), but not thereafter. However, in surgical patients mortality increased only beyond day 7 (8–30 days: 2·04, 95% CI 1·25–3·33; 31–365 days: 1·27, 95% CI 0·98–1·65). Thus, high magnitude of bacteraemia predicted mortality during the first month with a shift towards long-term mortality in surgical patients.

Osteoarthritis (OA) is associated with adverse cardio-metabolic features. N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity troponins T and I (hs-cTnT and hs-cTnI) are well-characterized cardiac markers and provide prognostic information. The objective was to assess the association of cardiac biomarker concentrations with long-term mortality in subjects with OA. In a cohort of 679 OA subjects, undergoing hip or knee replacement during 1995/1996, cardiac biomarkers were measured and subjects were followed over 20 years. During a median follow-up of 18.4 years, 332 (48.9%) subjects died. Median of hs-cTnT, hs-cTnI, and NT-proBNP at baseline was 3.2 ng/L, 3.9 ng/L, and 96.8 ng/L. The top quartile of NT-proBNP was associated with increased risk of mortality (Hazard Ratio (HR) 1.79, 95% confidence interval (CI) 1.17–2.73) after adjustment for covariates including troponins (hs-cTnT HR 1.30 (95% CI 0.90–1.89), hs-cTnI HR 1.32 (95% CI 0.87–2.00) for top category). When biomarker associations were evaluated as continuous variables, only NT-proBNP (HR per log-unit increment 1.34, 95% CI 1.16–1.54) and hs-cTnI (HR 1.38, 95% CI 1.11–1.72) showed robust results. Elevated cardiac biomarker concentrations predicted an increased risk of long-term mortality and strongest for NT-proBNP and hs-cTnI. These results might help to identify subjects at risk and target preventive efforts early.

Abstract BackgroundThe association between one-hour plasma glucose (1h-PG) and the incidence of type 2 diabetes has been investigated in previous studies. However, the predictive value of 1h-PG for the risk of cardiovascular disease (CVD) and all-cause mortality, especially in older Asians, has been investigated in only a few studies. Therefore, the influence of 1h-PG on the incidence of CVD and mortality was evaluated in the present study. MethodsThe participants were recruited from the Chinese People’s Liberation Army General Hospital, and were categorized into 1h-PG tertiles. The primary outcomes were all-cause mortality, myocardial infarction, unstable angina, and stroke. Multivariate adjusted Cox proportional hazard regression models were performed to examine the association between risk factors and outcomes and to estimate the risk of CVD and all-cause mortality based on 1h-PG.ResultsThe study included 862 male participants. Median age was 74.0 (25th–75th percentile: 68.0–79.0) years. There were 480 CVD events and 191 deaths during 15,527 person-years of follow-up. The adjusted hazard ratio (HR) of 1h-PG as a continuous variable was 1.097 (95% CI 1.027–1.172; P = 0.006) for CVD events and 1.196 (95% CI 1.115-1.281; P < 0.001) for higher risk of mortality. When compared with the lowest 1h-PG tertile, the other tertiles were associated with CVD events (HR 1.464, 95% CI 1.031–2.080; P = 0.033 and HR 1.538, 95% CI 1.092–2.166; P = 0.014, for tertile 2 and tertile 3 compared with tertile 1, respectively), and the highest 1h-PG tertile had a significantly higher risk of mortality (HR 2.384, 95% CI 1.631-3.485; P < 0.001) after full adjustment.ConclusionHigher 1h-PG is associated with an increased risk of all-cause mortality and CVD. 1h-PG might be a better predictor of CVD than 2h-PG in older adults.

BackgroundUnemployment has been reported to be associated with an increased risk of mortality. While most available studies focused on the effects of temporary unemployment on mortality, it remains unclear whether similar trends can be found in subjects who were never employed or are retirement. Therefore, this study examined the associations between temporary unemployment, never employed and retirement, integrating the risk of all-cause and cause-specific mortality in US adults.MethodsData from the National Health Interview Survey from 2001 to 2013 Linked Mortality files through 31 December 2015 were used. A total of 282 364 participants aged 18 to 65 years were included. Their employment status was categorised into four groups: employed, never employed, temporary unemployed and retired.ResultsDuring the mean follow-up time of 8.2 years, 12 645 subjects died from a variety of causes. Compared with employed participants, temporary unemployed, never employed or retired participants faced an increased risk of mortality for all-cause (temporary unemployed HR 1.76, 95% CI 1.67 to 1.86; never employed HR 1.63, 95% CI 1.47 to 1.81; retired HR 1.27, 95% CI 1.17 to 1.37). Cause-specific mortality analysis showed that compared with employed participants, temporary unemployed or never employed participants faced a significantly increased risk of mortality from cancer, cardiovascular disease, chronic lower respiratory disease, diabetes and kidney disease.ConclusionThis study showed that retired, temporary unemployed and never employed participants aged 18 to 65 years were strongly associated with higher mortality, indicating that both temporary and long-term unemployment are associated with a higher risk of mortality and adversely affect longevity.

Abstract Background Lower systolic blood pressure (SBP) at admission or discharge was associated with poor outcomes in patients with heart failure and preserved ejection fraction (HFpEF). However, the optimal long-term SBP for HFpEF was less clear. Purpose To examine the association of long-term SBP and all-cause mortality among patients with HFpEF. Methods We analyzed participants from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) study. Participants had at least two SBP measurements of different times during the follow-up were included. Long-term SBP was defined as the average of all SBP measurements during the follow-up. We stratified participants into four groups according to long-term SBP: &lt;120mmHg, ≥120mmHg and &lt;130mmHg, ≥130mmHg and &lt;140mmHg, ≥140mmHg. Multivariable adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) for all-cause mortality associated with SBP level. To assess for nonlinearity, we fitted restricted cubic spline models of long-term SBP. Sensitivity analyses were conducted by confining participants with history of hypertension or those with left ventricular ejection fraction≥50%. Results The 3338 participants had a mean (SD) age of 68.5 (9.6) years; 51.4% were women, and 89.3% were White. The median long-term SBP was 127.3 mmHg (IQR 121–134.2, range 77–180.7). Patients in the SBP of &lt;120mmHg group were older age, less often female, less often current smoker, had higher estimated glomerular filtration rate, less often had history of hypertension, and more often had chronic obstructive pulmonary disease and atrial fibrillation. After multivariable adjustment, long-term SBP of 120–130mmHg and 130–140mmHg was associated with a lower risk of mortality during a mean follow-up of 3.3 years (HR 0.65, 95% CI: 0.49–0.85, P=0.001; HR 0.66, 95% CI 0.50–0.88, P=0.004, respectively); long-term SBP of &lt;120mmHg had similar risk of mortality (HR 1.03, 95% CI: 0.78–1.36, P=0.836), compared with long-term SBP of ≥140mmHg. Findings from restricted cubic spline analysis demonstrate that there was J-shaped association between long-term SBP and all-cause mortality (P=0.02). These association was essentially unchanged in sensitivity analysis. Conclusions Among patients with HFpEF, long-term SBP showed a J-shaped pattern with all-cause mortality and a range of 120–140 mmHg was significantly associated with better outcomes. Future randomized controlled trials need to evaluate optimal long-term SBP goal in patients with HFpEF. Funding Acknowledgement Type of funding source: Foundation.
