- BACKGROUND: Increased somatostatin plasma concentration has been found in patients with vascular dementia. However, it is unknown whether or not somatostatin levels may predict dementia development in the general population. To this end, we sought to assess the association of circulating N-terminal prosomatostatin (NT-proSST) with incident dementia among community-dwelling older adults.METHODS: In the prospective population-based Malmö Preventive Project, 5,347 study participants (mean age: 69 ± 6years; 70% men) provided plasma for the determination of NT-proSST concentration. Of these, 373 participants (7%) were diagnosed with dementia (120 Alzheimer's disease, 83 vascular, 102 mixed, and 68 other aetiology) during a follow-up period of 4.6 ± 1.3 years. The association of NT-proSST with the risk of dementia and its subtypes was studied using multivariable-adjusted Cox regression models controlling for age, gender, body mass index, systolic blood pressure, antihypertensive treatment, smoking, diabetes, lipid levels and prevalent stroke.RESULTS: Higher levels of NT-proSST were significantly associated with an increased risk of vascular dementia (hazard ratio [HR] per 1 SD: 1.29; 95% CI 1.05-1.59; p = 0.016), whereas no association was observed with Alzheimer's disease (HR per 1 SD: 0.99; 95% CI 0.81-1.20; p = 0.91), all-cause dementia (HR per 1 SD: 1.04; 95% CI 0.94-1.16; p = 0.44), and mixed dementia (HR per 1 SD: 0.98; 95% CI 0.79-1.21; p = 0.84). Levels of NT-proSST above 563 pmol/L (highest quartile) conferred distinctly increased risk of vascular dementia (HR 1.66; 95% CI 1.05-2.63; p = 0.029) compared with lower values.CONCLUSIONS: Higher levels of circulating N-terminal-prosomatostatin are associated with increased incidence of vascular dementia. Our findings might be of importance for the understanding of dementia development in older adults.

- Previous reports have shown ambiguous findings regarding the possible associations between ischaemic stroke (IS) and single nucleotide polymorphisms (SNPs) in the phosphodiesterase 4D (PDE4D) gene region. The SNP rs12188950 (or SNP45) has often been studied in this context. We performed a multi-centre study involving a large sample of 2599 IS patients and 2093 control subjects from the south and west regions of Sweden to replicate previous studies regarding IS risk and rs12188950. Subjects from Lund Stroke Register (LSR), Malmo Diet and Cancer Study (MDC) and Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS) were enroled. Subgroups of participants with hypertension and participants <55 years of age, as well as the TOAST subgroups large vessel disease, small vessel disease and cardioembolism, were also assessed. Univariate odds ratios (ORs) and ORs controlling for hypertension, diabetes and current smoking were calculated. We additionally performed a meta-analysis including 10 500 patients and 10 102 control subjects from 17 publications (including the present study). When assessing pooled data from LSR, MDC and SAHLSIS we obtained no association between IS and rs12188950 for all participants (OR=0.93; 95% confidence interval (CI): 0.83-1.05). Significant associations were not found for hypertensive participants or participants with age <55, or when separately evaluating patients from the three different TOAST subgroups. The meta-analysis showed no significant overall estimate (OR=0.96; 95% CI: 0.89-1.04) with significant heterogeneity for random effect (P=0.042). No effect from rs12188950 on IS was found from either our pooled multi-centre data or the performed meta-analysis. We did not find any association between the examined subgroups and rs12188950 either. European Journal of Human Genetics (2012) 20, 783-789; doi: 10.1038/ejhg.2012.4; published online 25 January 2012

- BACKGROUND: Copeptin is a reliable surrogate marker for the neurohypophyseal hormone vasopressin. Elevated plasma level of copeptin has been associated with cardiovascular and metabolic disease risk.OBJECTIVE: To investigate the association between copeptin and risk of dementia.METHODS: In all, 18,240 individuals from Malmö, Sweden, were examined between 2002 and 2006 (mean age 69.3 years, 69.8% men). Incident cases of dementia until 31 December 2009 were identified by linkage with the Swedish National Patient Register. To validate the dementia diagnoses, medical records as well as laboratory and neuroimaging data were carefully reviewed. Baseline level of copeptin was measured in frozen plasma in: (1) all participants who were diagnosed with dementia during follow-up, (2) a random sample of 5100 individuals of the cohort.RESULTS: During a median follow-up of 4.2 years, there were 374 incident dementia cases (age range 60-83 years at baseline): 120 were classified as Alzheimer's disease (AD), 84 as vascular dementia (VaD), and 102 as mixed dementia. In logistic regressions adjusted for cardiovascular risk factors, baseline level of copeptin predicted incident VaD (Odds ratio (OR) 1.30 per 1 SD increase in log copeptin, 95% CI 1.03-1.64). Copeptin did not predict incidence of all-cause dementia (OR 1.05, 95% CI 0.94-1.18), AD (OR 0.97, 95% CI 0.79-1.18), or mixed dementia (OR 0.85, 95% CI 0.68-1.05).CONCLUSION: Elevated plasma level of copeptin is a risk marker for incident VaD, but not for incident AD. This suggests that the vasopressin hormonal system might be involved in the development of VaD.

Tidskriftsartikel (refereegranskat)abstract
- Pathogenesis of abdominal aortic aneurysm (AAA) is unclear. The aim of this study was to evaluate inflammatory and hemodynamic plasma biomarkers as predictors for AAA in the prospective longitudinal cohort of middle-aged individuals from the cardiovascular cohort of the Malmö Diet and Cancer Study ( n=5551; 1991-94). C-reactive protein, cystatin C, copeptin, N-terminal pro-B-type natriuretic peptide (N-BNP), midregional pro-atrial natriuretic peptide (MR-proANP) and conventional risk factors at baseline were measured in patients with incident AAA during follow-up and compared to individuals without a diagnosis of AAA. Subjects were followed until 31 December 2013. Multivariable analyses were expressed in terms of hazard ratios (HR) per 1 standard deviation increment of each respective log-transformed plasma biomarker in the Cox proportional hazard models. Mean follow-up time was 20.7 years. Cumulative incidence of AAA was 1.5% (men 2.9%, women 0.5%). Mean age of individuals with incident AAA was 59.7 years at study entry and AAA was diagnosed on average 14 years later. Adjusting for age, sex, smoking, body mass index, hypertension and diabetes mellitus, N-BNP (HR 1.29; 95% CI 1.03-1.62), but not MR-proANP (HR 1.20; 95% CI 0.95-1.50), was independently associated with incident AAA. In conclusion, the plasma biomarker N-BNP was associated with future development of AAA, which implies that this marker is a sensitive indicator of early subclinical cardiovascular disease.

- Prospective clinical plasma biomarker studies in abdominal aortic aneurysm (AAA) pathogenesis have been hampered by the need for very large cohorts and long follow-up time. The main aim of the present study was to evaluate the association of adrenomedullin, a cardiovascular (CV) stress marker, and incident AAA risk. Prospective longitudinal cohort of middle-aged individuals from the CV cohort of the Malmö Diet and Cancer Study (n = 5551; 1991-1994) was assessed. Plasma concentrations of midregional proadrenomedullin (MR-proADM), C-reactive protein (CRP), and conventional risk factors were measured at baseline. Incidence of AAA was studied up to December 31, 2013. Cumulative incidence of AAA was 1.5% (men 2.9%, women 0.5%). Mean age of individuals with incident AAA was 59.7 years at study entry, and AAA was diagnosed on average 14 years later. Adjusting for age, gender, smoking, body mass index, hypertension, diabetes mellitus, and CRP, MR-proADM (hazard ratio: 1.28; 95% confidence interval: 1.01-1.62) was independently associated with incident AAA. The plasma biomarker MR-proADM seems to be a marker of AAA risk, implying that AAA development may be driven by long-standing CV stress on the aortic wall.

- Background and aims The pathogenesis of abdominal aortic aneurysm (AAA) shares several common pathways with atherosclerosis. Prospective clinical plasma biomarker studies in AAA have been hampered by the need for very large cohorts and long follow-up time. Methods We analyzed a prospective longitudinal cohort of middle-aged individuals from the cardiovascular cohort of the Malmö Diet and Cancer study (n = 5551; 1991-94). The plasma biomarkers lipoprotein-associated phospholipase A2 (Lp-PLA2 activity and mass), proneurotensin and C-reactive protein, and conventional risk factors at baseline were measured in patients with incident AAA during follow-up, and compared to individuals without a diagnosis of AAA. Subjects were followed until December 31st, 2013. Multivariable analyses were expressed in terms of hazard ratios (HR) per 1 standard deviation increment of each respective log-transformed plasma biomarker in the Cox proportional hazard models. Results Cumulative incidence of AAA was 1.5% (men 2.9%, women 0.5%) during a median follow-up period of 20.7 years. Overall, 84 individuals had an incident AAA, of whom 22 (26.2%) were operated on and 16 (19.0%) had ruptured. Mean age of individuals with incident AAA was 59.7 years at study entry and AAA was diagnosed on average 14 years later. When adjusting for age, gender, smoking, body mass index, hypertension, and diabetes mellitus, Lp-PLA2 activity (HR 1.40; 95% CI 1.15–1.72) and Lp-PLA2 mass (HR 1.23; 95% CI 1.00–1.51) were independently associated with incident AAA. Conclusions The plasma biomarkers Lp-PLA2 activity and mass were markers of AAA risk and this implies that AAA is an athero-thrombotic related disease.

Tidskriftsartikel (refereegranskat)abstract
- Background: Traditional risk factors for atherosclerotic disease (AD) are well-known, of which some are relevant also for abdominal aortic aneurysms (AAA). The present study compares the importance of plasma biomarkers and traditional risk factor profiles for incident AD without concomitant AAA (isolated AD) and AAA without concomitant AD (isolated AAA) during long-term follow-up. Methods: In the Malmö Diet and Cancer Study-cardiovascular cohort, 5,381 participants were free from atrial fibrillation or flutter, AD (coronary artery disease, atherothrombotic ischemic stroke, carotid artery disease, or peripheral artery disease), and AAA underwent blood sampling under standardized fasting conditions between 1991 and 1994. Cox proportional hazards regression analysis was used to calculate hazard ratios (HR) with 95% CIs. Results: During a median follow-up of 23.1 years, 1,152 participants developed isolated AD, and 44 developed isolated AAA. Adjusted HR for lipoprotein-associated phospholipase A2 (mass) (HR 1.53, 95% CI 1.14-2.04 vs. HR 1.05, 95% CI.99-1.12) was higher for incident isolated AAA compared to incident isolated AD, respectively. Mid-regional pro-adrenomedullin (MR-proADM) was associated with incident isolated AD (HR 1.17, 95% CI 1.1-1.25) and incident isolated AAA (HR 1.47, 95% CI 1.15-1.88). MR-proADM was correlated (r = 0.32; p < 0.001) to body mass index (BMI), and BMI was associated with increased risk of incident isolated AAA (HR 1.43, 95% CI 1.02-2). No participant with diabetes mellitus (DM) at baseline developed isolated AAA (0/44), whereas DM was associated with an increased risk of isolated AD (HR 2.57, 95% CI 2.08-3.18). Adjusted HR for male sex (HR 4.8, 95% CI 2.42-9.48, vs. HR 1.76, 95% CI 1.56-1.98) and current smoking (HR 4.79, 95% CI 2.42-9.47 vs. HR 1.97, 95% CI 1.73-2.23) were higher in the incident isolated AAA group compared to the incident isolated AD group, respectively. Conclusions: The data supports the view that components of vascular inflammation and cardiovascular stress drives AAA development, whereas glycated cross-links in abdominal aortic wall tissue may have a plausible role in reducing AAA risk in individuals with DM.
