- ObjectivePre-eclampsia and gestational diabetes mellitus (GDM) are two common pregnancy complications that affect birth outcomes and are associated with a long-term risk of cardiovascular disease (CVD). The aims of this study were to investigate if the pre-eclampsia association with CVD is independent of GDM and modified by body mass index (BMI) or GDM.DesignCase–control study.SettingSweden.PopulationCases were women with a first CVD event between 1991 and 2008 and a previous pregnancy who were matched with controls without CVD (1:5) by year of birth, age and region of birth.MethodsConditional logistic regression was used to evaluate the associations of GDM, pre-eclampsia and maternal BMI with CVD adjusted for potential confounders and effect modifications with interaction tests.Main outcome measuresCVD.ResultsThere were 2639 cases and 13 310 controls with complete data. Pre-eclampsia and GDM were independent risk factors for CVD (adjusted odds ratio [aOR] 2.59, 95% CI 2.12–3.17 and aOR 1.47, 95% CI 1.04–2.09, respectively). After stratifying by maternal BMI, the adjusted association of pre-eclampsia with CVD did not differ notably between BMI groups: normal weight (aOR 2.65, 95% CI 1.90–3.69), overweight (aOR 2.67, 95% CI 1.52–4.68) and obesity (aOR 3.03, 95% CI 0.74–12.4). Similar findings were seen when stratifying on GDM/non-GDM.ConclusionsPre-eclampsia and GDM are independent risk factors for later CVD and having both during pregnancy is a major risk factor for later CVD. The association between pre-eclampsia and CVD is not modified by BMI. Effective CVD preventive programs for high-risk women are urgently needed in order to improve women's long-term health.

- Aims/hypothesis Previous studies have shown that individuals with similar mean glucose levels (MG) or percentage of time in range (TIR) may have different HbA(1c) values. The aim of this study was to further elucidate how MG and TIR are associated with HbA(1c). Methods Data from the randomised clinical GOLD trial (n=144) and the follow-up SILVER trial (n=98) of adults with type 1 diabetes followed for 2.5 years were analysed. A total of 596 paired HbA(1c)/continuous glucose monitoring measurements were included. Linear mixed-effects models were used to account for intra-individual correlations in repeated-measures data. Results In the GOLD trial, the mean age of the participants (+/- SD) was 44 +/- 13 years, 63 (44%) were female, and the mean HbA(1c) (+/- SD) was 72 +/- 9.8 mmol/mol (8.7 +/- 0.9%). When correlating MG with HbA(1c), MG explained 63% of the variation in HbA(1c) (r=0.79, p<0.001). The variation in HbA(1c) explained by MG increased to 88% (r=0.94, p value for improvement of fit <0.001) when accounting for person-to-person variation in the MG-HbA(1c) relationship. Time below range (TBR; <3.9 mmol/l), time above range (TAR) level 2 (>13.9 mmol/l) and glycaemic variability had little or no effect on the association. For a given MG and TIR, the HbA(1c) of 10% of individuals deviated by >8 mmol/mol (0.8%) from their estimated HbA(1c) based on the overall association between MG and TIR with HbA(1c). TBR and TAR level 2 significantly influenced the association between TIR and HbA(1c). At a given TIR, each 1% increase in TBR was related to a 0.6 mmol/mol lower HbA(1c) (95% CI 0.4, 0.9; p<0.001), and each 2% increase in TAR level 2 was related to a 0.4 mmol/mol higher HbA(1c) (95% CI 0.1, 0.6; p=0.003). However, neither TIR, TBR nor TAR level 2 were significantly associated with HbA(1c) when accounting for MG. Conclusions/interpretation Inter-individual variations exist between MG and HbA(1c), as well as between TIR and HbA(1c), with clinically important deviations in relatively large groups of individuals with type 1 diabetes. These results may provide important information to both healthcare providers and individuals with diabetes in terms of prognosis and when making diabetes management decisions.

- OBJECTIVE Continuous glucose monitoring (CGM) reduces HbA(1c) and time spent in hypoglycemia in people with type 1 diabetes (T1D) treated with multiple daily insulin injections (MDI) when evaluated over shorter time periods. It is unclear to what extent CGM improves and helps to maintain glucose control, treatment satisfaction, diabetes distress, hypoglycemic concerns, and overall well-being over longer periods of time. RESEARCH DESIGN AND METHODS The GOLD trial was a randomized crossover trial performed over 16 months of CGM treatment in people with T1D treated with MDI. People completing the trial (n = 141) were invited to participate in the current SILVER extension study in which 107 patients continued CGM treatment over 1 year along with the support of a diabetes nurse every 3 months. RESULTS The primary end point of the change in HbA(1c) over 1.0-1.5 years of CGM use compared with previous self-monitoring of blood glucose during GOLD showed a decrease in HbA(1c) of 0.35% (95% CI 0.19-0.50, P < 0.001). Time spent in hypoglycemia <3.0 mmol/L (54 mg/dL) and <4.0 mmol/L (72 mg/dL) decreased from 2.1% to 0.6% (P < 0.001) and from 5.4% to 2.9% (P < 0.001), respectively. Overall well-being (World Health Organization 5-item well-being index, P = 0.009), treatment satisfaction (Diabetes Treatment Satisfaction Questionnaire, P < 0.001), and hypoglycemic confidence (P < 0.001) increased, while hypoglycemic fear (Hypoglycemia Fear Survey-Worry, P = 0.016) decreased and diabetes distress tended to decrease (Problem Areas in Diabetes Scale, P = 0.06). From randomization and screening in GOLD, HbA(1c) was lowered by 0.45% (P < 0.001) and 0.68% (P < 0.001) after 2.3 and 2.5 years, respectively. CONCLUSIONS The SILVER study supports beneficial long-term effects from CGM on HbA(1c), hypoglycemia, treatment satisfaction, well-being, and hypoglycemic confidence in people with T1D managed with MDI.

- Context: Whether multisystem morbidity in Cushing's disease (CD) remains elevated during long-term remission is still undetermined.Objective: To investigate comorbidities in patients with CD.Design, setting, and patients: A retrospective, nationwide study of patients with CD identified in the Swedish National Patient Register between 1987 and 2013. Individual medical records were reviewed to verify diagnosis and remission status.Main outcomes: Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were calculated by using the Swedish general population as reference. Comorbidities were investigated during three different time periods: (i) during the 3 years before diagnosis, (ii) from diagnosis to 1 year after remission, and (iii) during long-term remission.Results: We included 502 patients with confirmed CD, of whom 419 were in remission for a median of 10 (interquartile range 4 to 21) years. SIRs (95% CI) for myocardial infarction (4.4; 1.2 to 11.4), fractures (4.9; 2.7 to 8.3), and deep vein thrombosis (13.8; 3.8 to 35.3) were increased during the 3-year period before diagnosis. From diagnosis until 1 year after remission, SIRs (95% CI were increased for thromboembolism (18.3; 7.9 to 36.0), stroke (4.9; 1.3 to 12.5), and sepsis (13.6; 3.7 to 34.8). SIRs for thromboembolism (4.9; 2.6 to 8.4), stroke (3.1; 1.8 to 4.9), and sepsis (6.0; 3.1 to 10.6) remained increased during long-term remission.Conclusion: Patients with CD have an increased incidence of stroke, thromboembolism, and sepsis even after remission, emphasizing the importance of early identification and management of risk factors for these comorbidities during long-term follow-up.

- Context: Whether patients with Cushing disease (CD) in remission have increased mortality is still debatable. Objective: To study overall and disease-specific mortality and predictive factors in an unselected nationwide cohort of patients with CD. Design, Patients, and Methods: A retrospective study of patients diagnosed with CD, identified in the Swedish National Patient Registry between 1987 and 2013. Medical records were systematically reviewed to verify the diagnosis. Standardized mortality ratios (SMRs) with 95% CIs were calculated and Cox regression models were used to identify predictors of mortality. Results: Of 502 identified patients with CD (n = 387 women; 77%), 419 (83%) were confirmed to be in remission. Mean age at diagnosis was 43 (SD, 16) years and median follow-up was 13 (interquartile range, 6 to 23) years. The observed number of deaths was 133 vs 54 expected, resulting in an overall SMR of 2.5 (95% CI, 2.1 to 2.9). The commonest cause of death was cardiovascular diseases (SMR, 3.3; 95% CI, 2.6 to 4.3). Excess mortality was also found associated with infections and suicide. For patients in remission, the SMR was 1.9 (95% CI, 1.5 to 2.3); bilateral adrenalectomy and glucocorticoid replacement therapy were independently associated with increased mortality, whereas GH replacement was associated with improved outcome. Conclusion: Findings from this large nationwide study indicate that patients with CD have excess mortality. The findings illustrate the importance of achieving remission and continued active surveillance, along with adequate hormone replacement and evaluation of cardiovascular risk and mental health.

- Background: Studies on the incidence of Cushing’s disease (CD) are few and usually limited by a small number of patients. The aim of this study was to assess the annual incidence in a nationwide cohort of patients with presumed CD in Sweden.Methods: Patients registered with a diagnostic code for Cushing’s syndrome (CS) or CD, between 1987 and 2013 were identified in the Swedish National Patient Registry. The CD diagnosis was validated by reviewing clinical, biochemical, imaging, and histopathological data.Results: Of 1317 patients identified, 534 (41%) had confirmed CD. One-hundred-and-fifty-six (12%) patients had other forms of CS, 41 (3%) had probable but unconfirmed CD, and 334 (25%) had diagnoses unrelated to CS. The mean (95% confidence interval) annual incidence between 1987 and 2013 of confirmed CD was 1.6 (1.4–1.8) cases per million. 1987–1995, 1996–2004, and 2005–2013, the mean annual incidence was 1.5 (1.1–1.8), 1.4 (1.0–1.7) and 2.0 (1.7–2.3) cases per million, respectively. During the last time period the incidence was higher than during the first and second time periods (P < 0.05).Conclusion: The incidence of CD in Sweden (1.6 cases per million) is in agreement with most previous reports. A higher incidence between 2005 and 2013 compared to 1987–2004 was noticed. Whether this reflects a truly increased incidence of the disease, or simply an increased awareness, earlier recognition, and earlier diagnosis can, however, not be answered. This study also illustrates the importance of validation of the diagnosis of CD in epidemiological research.

Tidskriftsartikel (refereegranskat)abstract
- In Sweden, diet-treated gestational diabetes mellitus (GDM) pregnancies have been managed as low risk. The aim was to evaluate the risk of adverse perinatal outcomes among women with diet-treated GDM compared with the background population and with insulin-treated GDM. This is a population-based cohort study using national register data between 1998 and 2012, before new GDM management guidelines and diagnostic criteria in Sweden were introduced. Singleton pregnancies (n = 1,455,580) without pregestational diabetes were included. Among 14,242 (1.0%) women diagnosed with GDM, 8851 (62.1%) were treated with diet and 5391 (37.9%) with insulin. In logistic regression analysis, the risk was significantly increased in both diet- and insulin-treated groups (vs. background) for large-for-gestational-age newborns, preeclampsia, cesarean section, birth trauma and preterm delivery. The risk was higher in the insulin-treated group (vs. diet) for most outcomes, but perinatal mortality rates neither differed between treatment groups nor compared to the background population. Diet as a treatment for GDM did not normalize pregnancy outcomes. Pregnancies with diet-treated GDM should therefore not be considered as low risk. Whether changes in surveillance and treatment improve outcomes needs to be evaluated.

Metformin as treatment of GDM
- 2023

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: Whether metformin should be used as treatment for gestational diabetes mellitus (GDM) is a matter of controversy. Concerns about the effects on neonatal birth weight (mainly small for gestational age, SGA) have been raised in one randomized controlled trial in type 2 diabetes in pregnancy. [1] The aim of this study was to evaluate pregnancy outcomes based on different GDM treatment modalities with focus on metformin.Methods: A cohort study, based on data from the stepped wedge cluster randomized trial; CDC4G (Changing diagnostic criteria for GDM in Sweden - www.cdc4g.se). Screening for GDM involved repeated random plasma glucose measurements and/or clinical risk factors. [2] Data were collected from electronic case record forms, and national health and quality registers. Singleton pregnancies during 2018 (last birth in August 2019) from eight clusters were included. Women with pregestational diabetes and/or previous gastric bypass surgery were excluded. Pregnancy outcomes for different treatment regimens were analyzed for women with GDM compared to the background population without GDM. Logistic regression analyzes with adjustments for confounders (body mass index, age, smoking, country of birth, chronic hypertensive disease and cluster) was performed (adjusted odds ratio (aOR) with 95% confidence interval (CI)) for all outcomes. Results: Of the 54 678 pregnancies included, 2 169 (4.0%) were diagnosed with GDM; of whom 1 076 (49.6%) were treated with diet only (dGDM), 668 (30.8%) with metformin only (mGDM), 116 (5.3%) with insulin only (iGDM), and 309 (14.2%) with both metformin and insulin (miGDM). Pregnancy outcomes were as follows: SGA (10th percentile) was significantly decreased in the mGDM group [aOR 0.57 (95% CI 0.41-0.79)] compared to the background population and no significant difference was found in the miGDM group [aOR 0.78 (95% CI 0.51-1.18)] compared to the background population. No significant difference in SGA (10th percentile) was found in the dGDM group [aOR 1.02 (CI 0.83-1.25)] compared to the background population. There was significant difference in neonates born large for gestational age (LGA, 90th percentile) in both mGDM and miGDM groups compared to the background population [aOR 2.29 (95% CI 1.88-2.78) and aOR 2.32 (95% CI 1.76-3.07), respectively]. There was not significant difference in LGA (90th percentile) in dGDM compared to the background population [aOR 0.90 (95% CI 0.73-1.12].Conclusions: These preliminary unpublished results show no increase in SGA for metformin treated GDM compared to the background population. Outcomes in the diet treated GDM group were similar to the background population. Further analyzes are needed to compare outcomes between pharmacologic treatment groups and assess whether specific treatment regimens lead to similar outcomes in different subgroups (eg ethnicity, obesity and glucose values on diagnostic oral glucose tolerance test).References:1.Feig DS, Donovan LE, Zinman B, Sanchez JJ, Asztalos E, Ryan EA, et al.
