- BackgroundCadmium is a toxic metal with multiple adverse health effects, including risk of cardiovascular disease (CVD). The mechanistic link between cadmium and CVD is unclear. Our aim was to examine the associations between blood cadmium (B-Cd) and 88 potential protein biomarkers of CVD.MethodsB-Cd and 88 plasma proteins were measured in a community-based prospective cohort, the Malmo Diet and Cancer study. The primary analysis was performed in never smokers (n=1725). Multiple linear regression was used with adjustments for age and sex, and correction for multiple comparisons using the false discovery rate method. Proteins significantly associated with B-Cd were replicated in long-term former smokers (n=782). Significant proteins were then studied in relation to incidence of CVD (i.e., coronary events or ischemic stroke) in never smokers.ResultsFifteen proteins were associated with B-Cd in never smokers. Eight of them were replicated in long-term former smokers. Kidney injury molecule-1, fibroblast growth factor-23 (FGF23), tumor necrosis factor receptor-2, matrix metalloproteinase-12, cathepsin L1, urokinase plasminogen activator receptor, C-C motif chemokine-3 (CCL3), and chemokine (C-X3-C motif) ligand-1 were associated with B-Cd both in never smokers and long-term former smokers. Except for CCL3 and FGF23, these proteins were also significantly associated with incidence of CVD.ConclusionsB-Cd in non-smokers was associated with eight potential plasma biomarkers of CVD and kidney injury. The results suggest pathways for the associations between B-Cd and CVD and kidney injury.

- As cardio metabolic disease manifestations tend to cluster in families there is a need to better understand the underlying mechanisms in order to further develop preventive strategies. In fact, genetic markers used in genetic risk scores, important as they are, will not be able alone to explain these family clusters. Therefore, the search goes on for the so called missing heritability to better explain these associations. Shared lifestyle and social conditions in families, but also early life influences may be of importance. Gene-environmental interactions should be explored. In recent years interest has grown for the role of diet-microbiota associations, as microbiota patterns may be shared by family members. In the Malmö Offspring Study that started in 2013, we have so far been able to examine about 4700 subjects (18-71 years) representing children and grandchildren of index subjects from the first generation, examined in the Malmö Diet Cancer Study during 1991 to 1996. This will provide rich data and opportunities to analyse family traits of chronic disease across three generations. We will provide extensive genotyping and phenotyping including cardiovascular and respiratory function, as well as markers of glucose metabolism. In addition, also cognitive function will be assessed. A 4-day online dietary recall will be conducted and gut as well as oral microbiota analysed. The ambition is to provide one of the first large-scale European family studies with individual data across three generations, which could deepen our knowledge about the role of family traits for chronic disease and its underlying mechanisms.

- Aim: The metabolite 3-carboxy-4-methyl-5-propyl-2-furanpropionic acid (CMPF) is a fatty fish–intake biomarker. We investigated the association between plasma levels of CMPF in relation to gingival inflammation and periodontitis case definition, as well as the extent and severity variables. Materials and Methods: The Malmö Offspring Study is a population-based study, and the Malmö Offspring Dental Study (MODS) is its dental arm, including periodontal charting. Plasma CMPF was measured using liquid chromatography–mass spectrometry and studied in relation to periodontal diagnosis and parameters using multivariable linear or logistic regression modelling adjusting for age, sex, education, body mass index, fasting glucose, and smoking. Results: Metabolite data were available for 922 MODS participants. Higher CMPF levels were associated with less gingival inflammation (β = −2.12, p =.002) and lower odds of severe periodontitis (odds ratio [OR] = 0.74, 95% confidence interval [CI]: 0.56 to 0.98). Higher CMPF levels were also associated with more teeth (β = 0.19, p =.001), lower number of periodontal pockets (≥4 mm) (β = −1.07, p =.007), and lower odds of having two or more periodontal pockets of ≥6 mm (OR = 0.80, 95% CI: 0.65 to 0.98) in fully adjusted models. Conclusions: CMPF, a validated biomarker of fatty fish consumption, is associated with less periodontal inflammation and periodontitis. Residual confounding cannot be ruled out, and future studies are warranted.

Soluble Urokinase-type Plasminogen Activator Receptor (suPAR) and Impaired Kidney Function in the Population-based Malmö Diet and Cancer Study
- 2017
-
In: Kidney International Reports. - : Elsevier BV. - 2468-0249. ; 2:2, s. 239-247
-
Journal article (peer-reviewed)abstract
- INTRODUCTION: The soluble urokinase-type plasminogen activator receptor (suPAR) has recently been associated with a decline in kidney function and incidence of chronic kidney disease in patients with cardiovascular disease undergoing cardiac catheterization, yet little is known whether suPAR is associated with deterioration of kidney function in the general population.METHODS: In the population-based Malmö Diet and Cancer Study cohort, plasma levels of suPAR were quantified in 5381 participants at baseline (1991-1994), and creatinine was measured and used to calculate estimated glomerulus filtration rate (eGFR) at baseline and follow-up (2007-2012). Incident chronic kidney disease was defined as eGFR < 60 ml/min per 1.73 m2 at follow-up.RESULTS: Participants within the highest quartile of suPAR had a significantly lower mean eGFR at follow-up than those within the lowest quartile (mean 68 vs. 74 ml/min per 1.73 m2; P-trend = 4.3 × 10-7). In multivariate regression analysis, suPAR (per 1 SD increment of log-transformed suPAR) was associated with a decline in eGFR (P = 3.3 × 10-9) and incident chronic kidney disease (561 events, odds ratio = 1.25; 95% confidence interval, 1.10-1.41). Furthermore, we identified 110 cases of hospitalization due to impaired kidney function via linkage to national registers of inpatient and outpatient hospital diagnoses. During a mean follow-up time of 19 years, suPAR was associated with risk for hospitalization due to impaired kidney function (hazard ratio = 1.49; 95% confidence interval, 1.27-1.74) in multivariate Cox proportional hazard analysis.DISCUSSION: The increased suPAR level at baseline was associated with a significantly higher longitudinal decline in eGFR, higher incidence of chronic kidney disease, and hospitalization due to impaired kidney function in a cohort of healthy middle-aged participants.

- 2017
-
In: Stroke. - 1524-4628. ; 48:10, s. 2686-2692
-
Journal article (peer-reviewed)abstract
- BACKGROUND AND PURPOSE: ECP (eosinophil cationic protein) is a marker of eosinophil activity and degranulation, which has been linked to atherosclerosis and cardiovascular disease. We examined the relationship between ECP, carotid plaque, and incidence of stroke in a prospective population-based cohort.METHODS: The subjects participated in the Malmö Diet and Cancer Study between 1991 and 1994. A total of 4706 subjects with no history of stroke were included (40% men; mean age, 57.5 years). Carotid plaque was determined by B-mode ultrasound of the right carotid artery. Incidence of stroke was followed up during a mean period of 16.5 years in relation to plasma ECP levels.RESULTS: Subjects in the third tertile (versus first tertile) of ECP tended to have higher prevalence of carotid plaque (odds ratio: 1.18; 95% confidence interval: 1.003-1.39; P=0.044 after multivariate adjustments). A total of 258 subjects were diagnosed with ischemic stroke (IS) during follow-up. ECP was associated with increased incidence of IS after risk factor adjustment (hazard ratio, 1.57; 95% confidence interval: 1.13-2.18; for third versus first tertile; P=0.007). High ECP was associated with increased risk of IS in subjects with carotid plaque. The risk factor-adjusted hazard ratio for IS was 1.86 (95% confidence interval: 1.32-2.63) in subjects with carotid plaque and ECP in the top tertile, compared with those without plaque and ECP in the first or second tertiles.CONCLUSIONS: High ECP is associated with increased incidence of IS. The association between ECP and IS was also present in the subgroup with carotid plaque.

Lp-PLA2 activity and mass for prediction of incident abdominal aortic aneurysms : A prospective longitudinal cohort study
- 2017
-
In: Atherosclerosis. - : Elsevier BV. - 0021-9150. ; 262, s. 14-18
-
Journal article (peer-reviewed)abstract
- 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.

- RDW is a new and easily available risk marker for adverse cardiovascular outcomes and we agree that this may encourage a wider use in clinical practice. As pointed out by Balta et al [2], the underlying causal links are unclear. The causal links could hypothetically involve some of the factors mentioned by Balta et al [2], but also properties of the red cells per se. This article is protected by copyright.

Genome wide association study identifies two loci associated with cadmium in erythrocytes among never-smokers
- 2016
-
In: Hum Mol Genet. - : Oxford University Press (OUP). - 0964-6906 .- 1460-2083. ; 25:11, s. 2342-2348

Journal article (peer-reviewed)abstract
- Background: Cadmium is a non-essential toxic metal with multiple adverse health effects. Exposure in the general population occurs by smoking and diet. Cadmium in erythrocytes is a valid biomarker of exposure and body burden of cadmium. Objectives: We aimed to identify genetic variants related to concentrations of cadmium in erythrocytes. Methods: Erythrocyte cadmium was analyzed in 4432 individuals (1728 never smokers) from the Swedish population-based Malmo Diet and Cancer cohort. Genotyping was performed using the Illumina HumanOmniExpressExome Bead chip with genome-wide coverage. Genome wide analyses were performed in the whole sample and in never smokers. Results: No single nucleotide polymorphism (SNP) reached a genome-wide significant association with erythrocyte cadmium in the whole sample. However, in never smokers, 14 variants showed genome-wide significant relationships with erythrocyte cadmium after adjusting for age and sex. Thirteen variants were in linkage disequilibrium on chromosome 8q13.3 in the XKR9 and LACTB2 genes. The lead SNP on 8q13.3 was rs12681420 (minor allele G, minor allele frequency [MAF] = 0.46, beta: -0.11, P = 3.48 x 10(-11)), an intron variant within the XKR9 gene. The other significant locus, rs17574271 (minor allele C, MAF = 0.09, beta: 0.17, P = 6.18 x 10(-9)), was an intron variant within the DLGAP1 gene at chromosome 18p11.31. Conclusion: This genome-wide study of never smokers from the general population identified two independent regions related to erythrocyte cadmium. The strongest locus covers the XKR9 and LACTB2 genes, which both could have related functions in cadmium absorption and metabolism. Replication studies are needed to confirm the findings and mechanisms should be further investigated.
