  • Increased healthcare utilization costs following initiation of insulin treatment in type 2 diabetes A long-term follow-up in clinical practice
  • 2017
  • Ingår i: Primary Care Diabetes. - Elsevier. - 1751-9918 .- 1878-0210. ; 11:2, s. 184-192
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To compare long-term changes in healthcare utilization and costs for type 2 diabetes patients before and after insulin initiation, as well as healthcare costs after insulin versus non-insulin anti-diabetic (NIAD) initiation. Methods: Patients newly initiated on insulin (n = 2823) were identified in primary health care records from 84 Swedish primary care centers, between 1999 to 2009. First, healthcare costs per patient were evaluated for primary care, hospitalizations and secondary outpatient care, before and up to seven years after insulin initiation. Second, patients prescribed insulin in second line were matched to patients prescribed NIAD in second line, and the healthcare costs of the matched groups were compared. Results: The total mean annual healthcare cost increased from 1656 per patient 2 years before insulin initiation to 3814 seven years after insulin initiation. The total cumulative mean healthcare cost per patient at year 5 after second-line treatment was 13,823 in the insulin group compared to 9989 in the NIAD group. Conclusions: Initiation of insulin in type 2 diabetes patients was followed by increased healthcare costs. The increases in costs were larger than those seen in a matched patient population initiated on NIAD treatment in second-line. (C) 2016 The Author(s).

  • Effects of smoking cessation on insulin and cardiovascular risk factors--a controlled study of 4 months' duration
  • 1996
  • Ingår i: Journal of Internal Medicine. - Wiley-Blackwell. - 1365-2796. ; 240:4, s. 189-194
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To investigate the effects on serum lipids, plasma fibrinogen, plasma insulin, plasma C-peptide and blood glucose, of smoking cessation after 4 months. To develop a group-based smoking intervention programme in primary health care. SETTING: Twenty health centres in primary health care in southern Sweden. SUBJECTS: Four hundred habitual smokers (> 10 cigarettes per day-1, > 10 years), recruited by advertisement in local papers. INTERVENTION: The smokers were randomized, after stratification for age and sex, to one intervention group (n = 200) and one control group (n = 200). The intervention group was offered supportive group sessions and free nicotine supplementation (patches, chewing gum). MAIN OUTCOME MEASURES: All participants were investigated at the start and after 4 months (medical history, physical examination, laboratory evaluation). Blood samples were drawn for determination of glucose, insulin and C-peptide, both in the fasting state and during an oral glucose tolerance test (OGTT), and for measurement of lipoproteins, fibrinogen, nicotine and cotinine. RESULTS: In the intervention group 98 of the subjects (48%) had quit smoking after 4 months. They were compared with the 156 subjects in the control group (91%) who were still daily smokers during the whole period. There were no significant differences in any variable between the two (total) experimental groups at baseline. Plasma nicotine and cotinine decreased (P < 0.001) in the intervention group following smoking cessation, and weight increased by 2.7 kg. In the intervention group HDL-cholesterol increased by 11% (P < 0.001), whereas HbA1c increased by 2% (P < 0.05) only in the control group. No changes occurred in levels of glucose, insulin, C-peptide and fibrinogen. CONCLUSION: The smoking cessation programme had a success rate of almost 50% over 4 months. Smoking cessation was associated with a marked increase in HDL-cholesterol levels but did not affect glucose tolerance. A concomitant weight increase may have blunted any independent beneficial effect of smoking cessation on glucose metabolism.

  • Circulating Midregional Proadrenomedullin and Risk of Incident Abdominal Aortic Aneurysm : A Prospective Longitudinal Cohort Study
  • 2017
  • Ingår i: Angiology. - SAGE Publications. - 0003-3197.
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Lp-PLA2 activity and mass for prediction of incident abdominal aortic aneurysms : A prospective longitudinal cohort study
  • 2017
  • Ingår i: Atherosclerosis. - Elsevier. - 0021-9150. ; 262, s. 14-18
  • Tidskriftsartikel (refereegranskat)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.

  • Ceruloplasmin and atrial fibrillation: evidence of causality from a population-based Mendelian randomization study.
  • 2014
  • Ingår i: Journal of Internal Medicine. - Wiley-Blackwell. - 1365-2796. ; 275:2, s. 164-171
  • Tidskriftsartikel (refereegranskat)abstract
    • Inflammatory diseases and inflammatory markers secreted by the liver, including C-reactive protein (CRP) and ceruloplasmin, have been associated with incident atrial fibrillation (AF). Genetic studies have not supported a causal relationship between CRP and AF, but the relationship between ceruloplasmin and AF has not been studied. The purpose of this Mendelian randomization study was to explore whether genetic polymorphisms in the gene encoding ceruloplasmin are associated with elevated ceruloplasmin levels, and whether such genetic polymorphisms are also associated with the incidence of AF.

  • Self-rated health in relation to age and gender: influence on mortality risk in the Malmö Preventive Project.
  • 2005
  • Ingår i: Scandinavian Journal of Public Health. - Taylor & Francis. - 1651-1905. ; 33:3, s. 9-183
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: A study was undertaken to examine whether poor self-rated health (SRH) can independently predict all-cause mortality during 22-year follow-up in middle-aged men and women. Subjects and methods: Data are derived from a population-based study in Malmo¨ , Sweden. This included baseline laboratory testing and a self-administered questionnaire. The question on global SRH was answered by 15,590 men (mean age 46.4 years) and 10,089 women (49.4 years). Social background characteristics (occupation, marital status) were based on data from national censuses. Mortality was retrieved from national registers. Results: At screening 4,261 (27.3%) men and 3,085 (30.6%) women reported poor SRH. Among subjects rating their SRH as low, 1,022 (24.0%) men and 228 (7.4%) women died during follow-up. Corresponding figures for subjects rating their SRH as high were 1801 (15.9%) men and 376 (5.4%) women. An analysis of survival in subjects reporting poor SRH revealed an age-adjusted hazard risk ratio (HR, 95%CI) for men HR 1.5 (1.4–1.7), and for women HR 1.4 (1.2–1.6). The corresponding HR after adjusting for possible social confounders was for men HR 1.3 (1.1–1.4), and women HR 1.1 (0.9–1.4). When additional adjustment was made for biological risk factors the association for men was still significant, HR 1.2 (1.1–1.3). Conclusion: Poor SRH predicts increased long-term mortality in healthy, middle-aged subjects. For men the association is independent of both social background and selected biological variables. The adjustment for biological variables can be questioned as they might represent mediating mechanisms in a possible causal chain of events.

  • Improvement of the plasma lipoprotein pattern after institution of insulin treatment in diabetes mellitus
  • 1982
  • Ingår i: Diabetes Care. - American Diabetes Association. - 1935-5548. ; 5:3, s. 322-325
  • Tidskriftsartikel (refereegranskat)abstract
    • Plasma lipids and lipoproteins were studied in 26 nonobese diabetic patients, either newly diagnosed or unsatisfactorily controlled by oral antidiabetic treatment. Measurements were performed before and 3-4 mo after the institution of insulin treatment. In a subgroup of seven patients, the activities of lipoprotein lipase (LPL) and hepatic lipase (HL) in postheparin plasma and the elimination rate of exogenous triglyceride were also monitored. After beginning insulin treatment, diabetic control was improved as demonstrated by decreasing levels of HbA1. Mean plasma cholesterol and triglyceride levels decreased by about 10% (P less than 0.01) and 40% (P less than 0.05), respectively. The decrease in plasma cholesterol was largely accounted for by a fall in LDL cholesterol levels (-8%, P less than 0.05), while plasma HDL cholesterol concentrations increased by about 12% (P less than 0.01). The elimination rate of exogenous triglycerides increased significantly. There was a suggestive, but not significant, increase in LPL activity while the HL activity remained unchanged. It is concluded that the improved diabetic control after institution of insulin treatment results in a significant improvement of the plasma lipoprotein profile. Since the improvement of the lipoprotein pattern is not strictly correlated to the amelioration of indices reflecting glucose transport, we suggest that the plasma lipoprotein pattern may provide an additional tool for monitoring the degree of control in diabetes mellitus.

  • Influence of treatment with diethylstilbestrol for carcinoma of prostate on platelet aggregation and plasma lipoproteins
  • 1986
  • Ingår i: Urology. - Elsevier. - 1527-9995. ; 28:6, s. 469-471
  • Tidskriftsartikel (refereegranskat)abstract
    • Treatment of prostatic carcinoma with estrogens is accompanied by an increased risk for thromboembolic and cardiovascular complications. The underlying mechanisms are still unknown. Patients treated with diethylstilbestrol (DES) were compared with patients given no estrogen treatment regarding factors (platelet aggregation in vitro and plasma lipoproteins) that have been suggested to contribute to increased thrombogenesis and cardiovascular risk. The results do not show any increase in in vitro platelet aggregation in patients treated with DES compared with those given no treatment. This indicates that hyperaggregability does not contribute to the increased incidence in thromboembolic events seen in DES-treated patients. This is in contrast to the increased platelet aggregation previously described in patients treated with polyestradiolphosphate + etinylestradiol. The changes in plasma lipoproteins observed during DES-treatment are generally considered beneficial from an atherogenic point of view and do not appear to cause the elevated incidence of cardiovascular disease in these patients.

  • Plasma high density lipoproteins and lipolytic enzyme activities in diabetic patients
  • 1983
  • Ingår i: Acta Medica Scandinavica. - Norstedts. - 0001-6101. ; 213:2, s. 123-128
  • Tidskriftsartikel (refereegranskat)abstract
    • Eighty diabetic patients, consecutively selected from an out-patient clinic, were studied with regard to plasma lipoprotein levels, especially HDL. Patients treated with sulphonylureas had 24% lower HDL cholesterol concentrations (p less than 0.01) but only about 7% lower apo AI levels (n.s.) than those on insulin treatment. This difference could at least partly be explained by differences in age and type of diabetes. There was no relationship between the degree of diabetic control, as measured by fasting blood glucose levels, and HDL levels. In two subgroups of insulin-treated diabetics, selected to represent extremely low and high HDL levels (range 0.5-0.8 and 1.8-2.0 mmol/l, respectively) but matched with regard to age, duration of diabetes, insulin dosage and diabetic control, the activities of lipoprotein lipase and hepatic lipase in postheparin plasma were also recorded. The high HDL group had significantly higher lipoprotein lipase activities (p less than 0.01) and significantly lower hepatic lipase activities (p less than 0.05) than the low HDL group, supporting the hypothetical roles of these enzymes in HDL metabolism, and offering a tentative mechanism behind the large variability of HDL levels in diabetics.
