- Objective. To identify a potential therapeutic target for type 2 diabetes by comparing the subcutaneous interstitial fluid from type 2 diabetes patients and healthy men. Methods. Proteomics was performed on the interstitial fluid of subcutaneous adipose tissue obtained by microdialysis from 7 type 2 diabetes patients and 8 healthy participants. 851 proteins were detected, of which 36 (including galectin-1) showed significantly altered expression in type 2 diabetes. We also measured galectin-1 expression in: (1) adipocytes isolated from adipose tissue biopsies from these participants; (2) subcutaneous adipose tissue of 24 obese participants before, during and after 16 weeks on a very low calorie diet (VLCD); and (3) adipocytes isolated from 6 healthy young participants after 4 weeks on a diet and lifestyle intervention to promote weight gain. We also determined the effect of galectin-1 on glucose uptake in human adipose tissue. Results. Galectin-1 protein levels were elevated in subcutaneous dialysates from type 2 diabetes compared with healthy controls (p < 0.05). In agreement, galectin-1 mRNA expression was increased in adipocytes from the type 2 diabetes patients (p < 0.05). Furthermore, galectin-1 mRNA expression was decreased in adipose tissue after VLCD (p < 0.05) and increased by overfeeding (p < 0.05). Co-incubation of isolated human adipocytes with galectin-1 reduced glucose uptake (p < 0.05) but this was independent of the insulin signal. Conclusion. Proteomics of the interstitial fluid in subcutaneous adipose tissue in vivo identified a novel adipokine, galectin-1, with a potential role in the pathophysiology of type 2 diabetes.

- Background and aimPoor dental health status has been linked to increased risk of cardiovascular events in type 2 diabetes (T2D). Less is known about self-perceived dental health and cardiovascular risk. Our aim with this study was to investigate this association.MethodsRecruitment of T2D patients took place between 2005 and 2008 in Swedish primary care. Teeth satisfaction was assessed by questionnaire at baseline. The major adverse cardiovascular events (MACE) in this study were hospitalization due to myocardial infarction, stroke or cardiovascular death. Cox regression models were used.ResultsOut of 761 participants 601 had complete data. Ninety-two MACEs occurred (median follow-up time: 11.6 years). Those satisfied with their teeth (n = 458) had 61 events (1.2 events per 100 person-years), while those dissatisfied with teeth (n = 143) had 31 events (2.2 events per 100 person-years). Dissatisfaction with teeth was associated with an increased risk of MACE independent of age, sex and levels of CRP (HR 1.85, 95% CI 1.20 – 2.86).ConclusionsIn patients with T2D, dissatisfaction with teeth was associated with increased risk of MACE and may be considered as a marker of risk.

- BackgroundLicorice, through the effects of glycyrrhizic acid (GA), raises blood pressure (BP). The World Health Organization has suggested that 100 mg GA/d would be unlikely to cause adverse effects, but of 13 previously published studies none have been randomized and controlled and independently quantified the GA content.ObjectiveOur aim was to analyze the effects on home BP of a daily licorice intake containing 100 mg GA.MethodsHealthy volunteers were randomly assigned to start with either licorice or a control product in a nonblinded, 2 × 2 crossover study. Home BP was measured daily, and blood samples were collected at the end of each 2-wk period.ResultsThere were 28 participants and no dropouts. The median age was 24.0 y (interquartile range 22.8–27.0 y). During the licorice compared with control intake period, the systolic home BP increased [mean difference: 3.1 mm Hg (95% confidence interval [CI]: 0.8, 5.4 mm Hg) compared with −0.3 mm Hg (95% CI: −1.8, 1.3 mm Hg); P = 0.018] and renin and aldosterone were suppressed [mean change: −30.0% (95% CI: −56.7%, −3.3%) compared with 15.8% (95% CI: −12.8%, 44.4%); P = 0.003; and −45.1% (95% CI: −61.5%, −28.7%) compared with 8.2% (95% CI: −14.7%, 31.1%); P <0.001, respectively]. In the quartile of participants with the most pronounced suppression of renin and aldosterone, N-terminal prohormone of brain natriuretic peptide concentration increased during the licorice compared with control period [mean change: 204.1% (95% CI: −11.6%, 419.7%) compared with 72.4% (95% CI: −52.2%, 197.1%); P = 0.016].ConclusionsWe found licorice to be more potent than previously known, with significant increases in BP, after a daily intake of only 100 mg GA. Thus, the safe limit of intake of this substance might need to be reconsidered.

Home Blood Pressure in Health and Disease

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Hypertension is the most common preventable cause of premature all-cause mortality, primarily from cardiovascular disease (CVD). Individuals with dysglycemia, including prediabetes and diabetes, are at increased risk. Licorice intake raises blood pressure (BP) through the effects of glycyrrhizic acid (GA), but the true limit of safe intake is uncertain. Home BP has several benefits over BP measured at a clinic, including a higher predictive value for CVD. By combining office and home BP, it is possible to diagnose masked hypertension (MH), in which home but not office BP is elevated, and white coat hypertension (WCH), in which office but not home BP is elevated. The aim of this thesis was to advance our knowledge on home BP in relation to dysglycemia, markers of CVD, and licorice intake. The first 3 papers used data from the Linköping cohort of the prospective Swedish CArdioPulmonary bioImage Study (SCAPIS). Study IV was a randomized controlled cross-over study. Data was obtained from questionnaires, blood samples and office and home BP measurements. In studies I-III, pulse wave velocity (PWV), coronary artery calcium score (CACS), and carotid artery plaques as markers of CVD were also included. In Study I, we examined 5025 men and women aged 50-64 years old for the relation between dysglycemia and home BP. Both the systolic office and home BP measurements were positively as-sociated with dysglycemia. Participants with dysglycemia vs normoglycemia more often had MH. The findings were in line with previous research and strengthened the association between dysglycemia and MH. In Study II, we examined the associations between MH and markers of CVD in 4122 individuals without BP-lowering treatment. Of participants, 4.2% had MH, and these were more often men and had higher BMI than those with normotension. Participants with MH also had higher odds for CACS ≥100, an as-sociation which has previously been suggested as a trend.In Study III, we examined the relation between soluble P-se-lectin (sP-selectin) as a measure of thrombotic activity, plasma high-sensitivity C-reactive protein (hsCRP) as a measure of inflammation, and home BP in 4548 participants. Both markers were higher in each hypertension phenotype compared with sustained normotension. The quartile of participants with the highest sP-se-lectin values had higher odds for CACS ≥100 and carotid artery plaques. The association between sP-selectin and sustained hyper-tension was novel and not affected by adjustments for hsCRP. In Study IV, 28 healthy participants aged 18-30 years old were evaluated for the effects of a daily intake of licorice containing 100 mg of GA compared with a control product for 2 weeks. During the licorice intake period, the systolic home BP increased with 3.1 mmHg, and the suppression of serum aldosterone and plasma renin levels indicated that this was due to the licorice intake. In conclusion, this thesis further strengthens the idea that both home and office BP measurements have values beyond that of the other, and that home BP may be most valuable in individuals with dysglycemia and obesity, and in men. Finally, licorice may be more potent than previously known, suggesting the need for increased awareness.

- Background: Soluble P-selectin (sP-selectin) and high-sensitivity C-reactive protein (hsCRP) have previously been associated with hypertension, but the relation with out-of-office blood pressure (BP) and coronary artery calcification score is unknown. We aimed to examine the relationship between sP-selectin, hsCRP and home BP, as well as coronary artery calcification score and carotid artery plaques.Methods: In the Swedish CArdioPulmonary bioImage Study (SCAPIS), 5057 randomly selected participants were evaluated with office and home BP using the semi-automatic Omron M10-IT device. For this cross-sectional study, participants with sP-selectin <4 standard deviations above mean and hsCRP <5 mg/l, representing low-grade inflammation, were included. Using generalized linear models, these inflammatory markers were evaluated in relation to BP classifications, as well as coronary artery calcification score and carotid artery plaques.Results: Of participants, 4548 were included in the analyses. The median age was 57.2 (53.4–61.2) years, and 775 (17.0%) reported taking medication for hypertension. Participants in the highest quartile of sP-selectin [odds ratio (OR) 1.67, 95% confidence interval (CI) 1.40–1.98, P < 0.001] and hsCRP [OR 2.25, (95% CI 1.89–2.60), P < 0.001] were more likely to have sustained hypertension. Participants in the highest quartile of hsCRP were also more likely to have masked hypertension, OR (95% CI) 2.31 (1.72–3.10), P < 0.001 and carotid artery plaques, OR (95% CI) 1.21 (1.05–1.38), P = 0.007.Conclusion: Increased sP-selectin and hsCRP were independently associated with sustained hypertension. These findings indicate an association between hypertension and platelet activity, as expressed by sP-selectin.

- BackgroundInformation on alcohol consumption in patients undergoing radiofrequency ablation (RFA) of atrial fibrillation (AF) is often limited by the reliance on self-reports. The aim of this study was to describe the long-term alcohol consumption, measured as ethyl glucuronide in hair (hEtG), in patients undergoing RFA due to AF, and to examine potential associations with cardiac biomarkers, left atrial size and re-ablation within one year after the initial RFA.MethodsThe amount of hEtG was measured in patients referred for RFA, and a cut-off of 7 pg/mg was used. N-terminal pro B-type natriuretic peptide (NT-proBNP) and the mid-regional fragment of pro atrial natriuretic peptide (MR-proANP) were examined and maximum left atrium volume index (LAVI) was measured. The number of re-ablations was examined up to one year after the initial RFA. Analyses were stratified by gender, and adjusted for age, systolic blood pressure, body mass index, presence of heart failure and heart rhythm for analyses regarding NT-proBNP, MR-proANP and LAVI and heart rhythm being replaced by type of AF for analyses regarding re-ablation.ResultsIn total, 192 patients were included in the study. Median (25th– 75th percentile) NT-proBNP in men with hEtG ≥ 7 vs. < 7 pg/mg was 250 (96–695) vs. 130 (49–346) pg/ml (p = 0.010), and in women it was 230 (125–480) vs. 230 (125–910) pg/ml (p = 0.810). Median MR-proANP in men with hEtG ≥ 7 vs. < 7 pg/mg was 142 (100–224) vs. 117 (83–179) pmol/l (p = 0.120) and in women it was 139 (112–206) vs. 153 (93–249) pmol/l (p = 0.965). The median of maximum LAVI was 30.1 (26.7–33.9) vs. 25.8 (21.4–32.0) ml/m2 (p = 0.017) in men, and 25.0 (18.9–29.6) vs. 25.7 (21.7–34.6) ml/m2 (p = 0.438) in women, with hEtG ≥ 7 vs. < 7 pg/ml, respectively. Adjusted analyses showed similar results, except for MR-proANP turning out significant in men with hEtG ≥ 7 vs. < 7 pg/mg (p = 0.047). The odds ratio of having a re-ablation was 3.5 (95% CI 1.3–9.6, p = 0.017) in men with hEtG ≥ 7 vs. < 7 pg/mg, while there was no significant difference in women.ConclusionsIn male patients with AF and hEtG ≥ 7 pg/mg, NT-proBNP and MR-proANP were higher, LA volumes larger, and there was a higher rate of re-ablations, as compared to men with hEtG < 7 pg/mg. This implies that men with an alcohol consumption corresponding to an hEtG-value ≥ 7, have a higher risk for LA remodelling that could potentially lead to a deterioration of the AF situation.

- AimsObesity is associated with type 2 diabetes mellitus, left ventricular diastolic dysfunction and heart failure but it is unclear to which extent it is related to left ventricular systolic dysfunction. The aim of the study was to explore the effects of overweight and obesity on left ventricular systolic function in patients with type 2 diabetes mellitus and a control group of non-diabetic persons.MethodsWe prospectively investigated 384 patients with type 2 diabetes mellitus, and 184 controls who participated in the CARDIPP and CAREFUL studies. The participants were grouped according to body mass index (normal weight < 25 kg/m2, overweight 25–29 kg/m2, and obesity ≥ 30 kg/m2). Echocardiography was performed at the beginning of the study and after 4-years in the patient group.ResultsUnivariable and multivariable regression analysis revealed that variations in left ventricular ejection fraction, global longitudinal strain, left ventricular mass and diastolic function expressed as E/é (the ratio between early diastolic mitral flow and annular motion velocities) all are related to body mass index. The mean and standard deviation of left ventricular ejection fraction and global longitudinal strain values were 57% (8%) vs. − 18.6% (2.3%) for normal weight patients, 53% (8%) vs. − 17.5% (2.3%) for overweight, and 49% (9%) vs. − 16.2% (3.0%) for obese (p < 0.05 vs. p < 0.05). Corresponding results in the control group were 58% (6%) vs. − 22.3% (3.0%), 55% (7%) vs. − 20.8% (3.1%) and 54% (8%) − 19.6% (4.0%) (p < 0.05 vs. p < 0.05). Patients who gained weight from baseline to follow-up changed left ventricular ejection fraction (median and interquartile range) by − 1.0 (9.0) % (n = 187) and patients who lost weight changed left ventricular ejection fraction by 1.0 (10.0) % (n = 179) (p < 0.05).ConclusionOverweight and obesity impair left ventricular ejection fraction and global longitudinal strain in both patients with type 2 diabetes mellitus and non-diabetic persons.

- Background: Predicting the risk of readmission or death in patients at the emergency department (ED) is essential in identifying patients who would benefit the most from interventions. We aimed to explore the prognostic value of mid-regional proadrenomedullin (MR-proADM), mid-regional pro-atrial natriuretic peptide (MR-proANP), copeptin, and high-sensitivity troponin T (hs-TnT) to identify patients with a higher risk of readmission and death among patients presenting with chest pain (CP) and/or shortness of breath (SOB) in the ED.Methods: This single-center prospective observational study included non-critically ill adult patients with a chief complaint of CP and/or SOB who visited the ED at Linköping University Hospital. Baseline data and blood samples were collected, and patients were followed up for 90 days after inclusion. The primary outcome was a composite of readmission and/or death from non-traumatic causes within 90 days of inclusion. Binary logistic regression was used and receiver operating characteristics (ROC) curves were constructed to determine the prognostic performance for predicting readmission and/or death within 90 days.Results: A total of 313 patients were included and 64 (20.4%) met the primary endpoint. MR-proADM > 0.75 pmol/L (odds ratio [OR]: 2.361 [95% confidence interval [CI]: 1.031 – 5.407], P = 0.042) and multimorbidity (OR: 2.647 [95% CI: 1.282 – 5.469], P = 0.009) were significantly associated with readmission and/or death within 90 days. MR-proADM increased predictive value in the ROC analysis to age, sex, and multimorbidity (P = 0.006).Conclusions: In non-critically ill patients with CP and/or SOB in the ED, MR-proADM and multimorbidity may be helpful for the prediction of the risk of readmission and/or death within 90 days.

- Cryoablation, which induces cellular death without extensive tissue damage, has been extensively used to denervate the myocardium. However, periadventitial external circumferential application of cryotherapy to denervate the renal artery sympathetic nerves has, to our knowledge, never been tested in humans. The main aim of this study was to examine the safety and potential effects of cryotherapy on ambulatory blood pressure levels and other outcomes that are indirectly related to sympathetic tone, including pulse-wave velocity, central pulse pressure, and glucose levels.
