Acromegaly management in the Nordic countries: A Delphi consensus survey.

OBJECTIVE: Acromegaly is associated with increased morbidity and mortality if left untreated. The therapeutic options include surgery, medical treatment, and radiotherapy. Several guidelines and recommendations on treatment algorithms and follow-up exist. However, not all recommendations are strictly evidence-based. To evaluate consensus on the treatment and follow-up of patients with acromegaly in the Nordic countries. METHODS: A Delphi process was used to map the landscape of acromegaly management in Denmark, Sweden, Norway, Finland, and Iceland. An expert panel developed 37 statements on the treatment and follow-up of patients with acromegaly. Dedicated endocrinologists (n = 47) from the Nordic countries were invited to rate their extent of agreement with the statements, using a Likert-type scale (1-7). Consensus was defined as ≥80% of panelists rating their agreement as ≥5 or ≤3 on the Likert-type scale. RESULTS: Consensus was reached in 41% (15/37) of the statements. Panelists agreed that pituitary surgery remains first line treatment. There was general agreement to recommend first-generation somatostatin analog (SSA) treatment after failed surgery and to consider repeat surgery. In addition, there was agreement to recommend combination therapy with first-generation SSA and pegvisomant as second- or third-line treatment. In more than 50% of the statements, consensus was not achieved. Considerable disagreement existed regarding pegvisomant monotherapy, and treatment with pasireotide and dopamine agonists. CONCLUSION: This consensus exploration study on the management of patients with acromegaly in the Nordic countries revealed a relatively large degree of disagreement among experts, which mirrors the complexity of the disease and the shortage of evidence-based data.

Desmopressin Dose Requirements in Adults with Congenital and Acquired Central Diabetes Insipidus.

Central diabetes insipidus is a rare disorder characterized by a deficiency of vasopressin. The first line drug to treat this disorder is a synthetic analogue of vasopressin, desmopressin.The primary aim of this retrospective register study was to compare desmopressin dose requirements in patients with acquired and congenital DI, and secondly to assess the influence of BMI on dose requirement and risk of hyponatremia with different drug administrations. We included all patients with suspected DI attending the endocrine department at Rigshospitalet, Copenhagen, Denmark in 2022. We identified 222 patients who were included whereof 130/222 (58.6%) were females and median age was 53 years (IQR 35 to 63). The etiology included 7/222 (3.2%) congenital and 215/222 (96.8%) acquired. After converting nasal and sublingual doses to equivalent oral doses, the median daily dose requirement was 600 µg in patients with congenital etiology compared to 200 µg in patients with acquired etiology (p=0.005). We found no association between BMI and desmopressin dose requirements (p=0.6). During the past 12 months, 66/215 (30.7%) had sodium levels<136 mmol/l including 20/215 (9.3%) with sodium levels<131 mmol/l. No increased risk of hyponatremia was found, when nasal and oral were compared (p=0.9). Daily desmopressin dose requirements were higher in patients with congenital DI compared to patients with acquired DI. However, this result was associated with uncertainty due to the small congenital group. BMI did not influence daily dose requirements and nor did type of administration influence the risk of hyponatremia.

Prognostic value of contralateral suppression on kidney function after surgery in patients with primary aldosteronism.

BACKGROUND AND OBJECTIVE: Adrenalectomy for primary aldosteronism (PA) has been associated with decreased kidney function after surgery. It has been proposed that elimination of excess aldosterone unmasks an underlying failure of the kidney function. Contralateral suppression (CLS) is considered a marker of aldosterone excess and disease severity, and the purpose of this study was to assess the hypothesis that CLS would predict change in kidney function after adrenalectomy in patients with PA. DESIGN AND PATIENTS: Patients with PA referred for adrenal venous sampling (AVS) between May 2011 and August 2021 and who were subsequently offered surgical or medical treatment were eligible for the current study. RESULTS: A total of 138 patients were included and after AVS 85/138 (61.6%) underwent adrenalectomy while 53/138 (38.4%) were treated with MR-antagonists. In surgically treated patients the estimated glomerular filtration rate (eGFR) was reduced by 11.5 (SD: 18.5) compared to a reduction of 5.9 (SD: 11.5) in medically treated patients (p = .04). Among surgically treated patients, 59/85 (69.4%) were classified as having CLS. After adrenalectomy, patients with CLS had a mean reduction in eGFR of 17.5 (SD: 17.6) compared to an increase of 1.8 (SD: 12.8) in patients without CLS (p < .001). The association between CLS and change in kidney function remained unchanged in multivariate analysis. Post-surgery, 16/59 (27.1%) patients with CLS developed hyperkalemia compared to 2/26 (7.7%) in patients without CLS (p = .04). CONCLUSION: This retrospective study found that CLS was a strong and independent predictor of a marked reduction of eGFR and an increased risk of hyperkalemia after adrenalectomy in patients with PA.

Natural History of Non-Functioning Pituitary Adenomas: A Systematic Review and Meta-Analysis.

The management of non-functioning pituitary tumors (NFPTs) relies on the risk of tumor growth and new endocrinopathies. The objective of this systematic review was to assess the risk of growth, new pituitary endocrinopathies, and surgery in patients with conservatively treated NFPTs. We conducted a bibliographical search identifying studies assessing NFPTs followed conservatively. Estimates were pooled using random-effects meta-analysis reporting events per 100 person years (PYs), in case of high heterogeneity (I2>75%) only the range of observed effects was reported. We identified 30 cohort studies including 1957 patients with a mean follow-up time of 4.0 (SD 1.5) years. The overall risk of tumor growth ranged from 0.0 to 14.2/100 PYs (I2=90%), while the overall risk of new endocrinopathies was 0.9/100 PYs (95% CI. 0.5 to 1.2; I2=: 35%) and risk of surgery ranged from 0.0 to 7.7/100 PYs (I2=: 80%). Compared to microadenomas, macroadenomas had higher risk of growth (p=: 0.002), higher risk of surgery (p=: 0.006), and non-significant differences in risk of new endocrinopathies (p=: 0.15). An analysis of microadenomas found the risk of growth to be 1.8/100 PYs (95% CI. 0.9 to 2.8; I2=: 58%), the risk of new endocrinopathies 0.7/100 PYs (95% CI. 0.0 to 1.6; I2=: 37%) and the risk of surgery 0.5/100 PYs (0.1 to 0.9; I2=: 37%). These data support individualized follow-up strategies of patients with NFPTs and particularly a less rigorous follow-up of patients with microadenomas.

Prognostic value of contralateral suppression for remission after surgery in patients with primary aldosteronism.

OBJECTIVE: Primary aldosteronism (PA) is the most common cause of endocrine hypertension and adrenalectomy is the firstline treatment for unilateral PA. Suppression of aldosterone secretion of the nondominant adrenal gland at adrenal venous sampling (AVS), that is, contralateral suppression (CLS) has been suggested as a marker of disease severity. However, whether factors such as CLS, age, gender or comorbidities are associated with remission after surgery is controversial. The objective of this study is to investigate the prognostic value of CLS, age, gender, aldosterone-to-renin ratio, antihypertensives and comorbidities for clinical and biochemical remission following unilateral adrenalectomy in patients with PA. DESIGN AND PATIENTS: A retrospective study of patients with PA referred for AVS at Rigshospitalet from May 2011 to September 2020, who subsequently underwent adrenalectomy. Clinical remission was defined according to the PA surgical outcome criteria, whereas complete biochemical remission was defined as normalization of hypokalaemia without potassium substitution. RESULTS: Eighty-four patients were available for analysis of primary outcome. Among patients with CLS, 28/58 (48.3%) obtained complete clinical remission after surgery compared with 10/26 (38.5%) without CLS (p = .40). Complete biochemical remission was obtained in 55/58 (94.8%) of patients with CLS compared with 25/28 (89.3%) without CLS (p = .44). Female gender and lower number of antihypertensives at baseline were associated with higher odds for complete clinical remission, whereas none of the investigated variables were associated with biochemical remission. CONCLUSION: CLS was not significantly associated with complete clinical or biochemical remission in this cohort. Our results confirmed that female gender and lower number of antihypertensives were predictors of clinical remission.

Withdrawal of dopamine agonist treatment in patients with hyperprolactinaemia: A systematic review and meta-analysis.

OBJECTIVE: To estimate the proportion of patients with persistent normoprolactinaemia following dopamine agonist (DA) withdrawal and to identify predictors of successful withdrawal in patients with hyperprolactinaemia. DESIGN, PATIENTS, AND MEASUREMENTS: A systematic review of observational eligible studies were identified by searching PubMed and Embase. The primary outcome was the proportion of patients with normoprolactinaemia after cessation of DA treatment. Secondary outcome included the proportion of patients with normoprolactinaemia after DA withdrawal using individual patient data. Risk of bias was assessed by using Newcastle-Ottawa Scale. Pooled proportions were estimated using a random effects model in case I2 ≤ 75% or by reporting range of effects if I2 > 75%. RESULTS: Thirty-two observational studies enroling 1563 patients were included. The proportion of patients with persistent normoprolactinaemia ranged from 0% to 75% (I2 = 84%). Heterogeneity was partly explained by age with more successful withdrawal in patients of higher age. Individual patient data analyses suggested that the proportion of patients with persistent normoprolactinaemia 6 months after DA withdrawal with a low maintenance dose and full regression of the prolactinoma was 87.7% (95% confidence interval [CI] = 60.7-97.1; I2 = 0%) and 58.4% (95% CI = 23.8-86.3; I2 = 75%) for microadenomas and macroadenomas, respectively. CONCLUSIONS: The proportion of patients with persistent normoprolactinaemia following DA withdrawal treatment varied greatly, partly explained by the mean age of participants of the individual studies. Individual patient data analysis suggested that successful withdrawal was likely in patients with full regression of prolactinomas using a low maintenance dose before cessation.

Endocrine Function after Transsphenoidal Surgery in Patients with Non-Functioning Pituitary Adenomas: A Systematic Review and Meta-Analysis.

INTRODUCTION: Transsphenoidal surgery is the current treatment for mass reduction in patients with non-functional pituitary adenomas (NFPAs). The surgical procedure may deteriorate or recover pituitary endocrine function. The aim of this study was to systematically assess the benefits and harms of transsphenoidal surgery on pituitary endocrine function in patients with NFPAs. METHODS: This systematic review and meta-analysis was registered with PROSPERO (registration No. CRD42020210853). We searched Pubmed and EMBASE for studies reporting on pituitary function before and after transsphenoidal surgery in patients with NFPAs having a minimum follow-up of 1 month. The prespecified primary outcomes were the proportions of patients with improved or deteriorated pituitary function after surgery reported as weighted mean using random effects meta-analysis or in case of considerable heterogeneity, i.e., I2 ≥ 75%, as a range of reported proportions. Subgroup analyses were planned for the primary outcomes on study level. RESULTS: Of the 6,597 identified records, 24 studies enrolling 3,816 participants were eligible for assessment. Twenty-three studies were judged to have serious or critical risk of bias. The range of proportions of patients with recovery of at least one pituitary axis was between 10.2% and 97.7% (I2 = 93%), while the range of proportions of patients experiencing loss of at least one axis after pituitary surgery was between 0.0% and 36.6% (I2 = 91%). None of the a priori planned subgroup analyses explained the observed heterogeneity associated with deterioration of pituitary function after surgery, and the proportion of patients may be underestimated due to publication bias. CONCLUSIONS: The current systematic review finds that the endocrine effect of pituitary surgery is unclear both in terms of the chance of recovery and in terms of the risk of pituitary failure and hypopituitarism should be considered only a relative indication for surgery. However, the range of effects does include potentially clinically relevant rates of pituitary recovery calling for more systematic collection of data in future studies.

Metabolic and hormonal side effects of mitotane treatment for adrenocortical carcinoma: A retrospective study in 50 Danish patients.

OBJECTIVE: Mitotane is used in the treatment of adrenocortical carcinoma (ACC). Metabolic and hormonal side effects of mitotane, the effect of subsequent treatment with statins and hormones and the effects of discontinuation of mitotane were assessed. PATIENTS AND METHODS: Fifty patients were included. Lipid profiles, thyroid hormones, sex hormones and adrenal function from first year of mitotane treatment and after cessation were evaluated. RESULTS: After 6 months of mitotane treatment total cholesterol increased from (median) 5.1 (IQR 4.3 to 5.8) to 7.4 (6.2-9.0) mmol/L, p < .001. LDL, HDL and triglyceride also increased, all p ≤ .03. Three months of treatment with statins decreased total and LDL-cholesterol, and cessation of mitotane led to further reduction in lipids. Plasma thyroxine decreased from 90 (78-111) to 57 (47-63) nmol/L and free thyroxine from 16.0 (13.0-18.3) to 11.7 (10.5-12.6) pmol/L on mitotane, both p < .001, while TSH remained unchanged. Treatment with thyroxin significantly increased plasma thyroxine and free thyroxine and decreased TSH. Cessation of mitotane increased total T4 (p < .001). Mitotane increased plasma SHBG from 36 (22-51) to 189 (85-259) nmol/L and LH from 4.6 (1.6-8.1) to 20.0 (10.0-34.9) IU/L, both p < .001. In males the changes were accompanied by an increase in testosterone from 9.8 (7.2-14.5) to 27.0 (15.3-34.8) nmol/L, p < .03. Fifteen of 24 tested patients regained normal adrenal function 6 (3-16) months after cessation of mitotane. CONCLUSIONS: Mitotane treatment exerts multiple severe side effects involving both the metabolic and endocrine systems that may require treatment, but the effect appears to be partially reversible.

The effect of sodium-glucose transport protein 2 inhibitors on mortality and heart failure in randomized trials versus observational studies.

AIM: Randomized clinical trials (RCTs) allocating type 2 diabetes patients to treatment with sodium-glucose transport protein 2 (SGLT-2) inhibitors or placebo have found significant effects on the risk of heart failure and modest effects on mortality. In the wake of the first trials, a number of observational studies have been conducted, some of these reporting a mortality reduction of 50% compared to active comparators. In this review, we systematically assess and compare the results on all-cause mortality, cardiovascular mortality and heart failure hospitalization observed in RCTs with the results obtained in observational studies. METHOD: We performed a systematic bibliographical search including cardiovascular outcome trials and observational studies assessing the effect of SGLT-2 inhibitors on mortality and heart failure. RESULTS: Seven RCTs and 23 observational studies were included in the current review. The observed heterogeneity between study results for all-cause mortality (p-interaction < 0.001) and cardiovascular mortality (p-interaction < 0.001) was explained by study type, whereas this was not the case for heart failure (p-interaction = 0.18). CONCLUSION: Methodological considerations such as the omission of important confounders, immortal-time bias and residual confounding such as unmeasured social economic inequality may be the cause of the inflated results observed in observational studies and that calls for caution when observational studies are used to guide treatment of patients with type 2 diabetes.

The effect of dopamine agonists on metabolic variables in adults with type 2 diabetes: A systematic review with meta analysis and trial sequential analysis of randomized clinical trials.

AIM: To assess the metabolic effects of dopamine agonists compared with placebo in randomized controlled trials (RCTs) including adults with type 2 diabetes. MATERIALS AND METHODS: Eligible trials were identified by searching PubMed, Embase and CENTRAL. The primary outcomes were HbA1c and serious adverse events (SAEs) assessed at longest available follow-up. Secondary outcomes were fasting plasma glucose, adverse events, body weight, hypoglycaemia and triglycerides. We assessed risk of bias and evaluated the certainty of the evidence with the Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Nine RCTs enrolling 3456 participants were included, six of which assessed the effect of bromocriptine, and the other three the effect of cabergoline. Dopamine agonists reduced HbA1c with 0.69 standardized mean difference (95% CI = 0.28 to 1.09; P = .0008; I2 = 80%; GRADE: low) compared with placebo. There was no difference in the effect between bromocriptine and cabergoline. Heterogeneity was partly explained by dosage and study duration, both of which were inversely associated with effect size. Only one large trial reported SAEs and no difference was reported for the risk of an SAE (RR = 0.89; 95% CI = 0.70 to 1.12; P = .32) between active intervention and placebo. Secondary outcomes suggested a decrease in fasting plasma glucose and triglycerides and no effect on the remaining outcomes. CONCLUSION: Dopamine agonists reduce HbA1c as well as fasting plasma glucose and triglycerides in patients with type 2 diabetes without causing SAEs. These data are based on moderate to low quality evidence thus our confidence in the effect estimates is limited.

Cerebrospinal fluid markers of inflammation and infections in schizophrenia and affective disorders: a systematic review and meta-analysis.

Infections and inflammatory processes have been associated with the development of schizophrenia and affective disorders; however, no study has yet systematically reviewed all available studies on cerebrospinal fluid (CSF) immune alterations. We aimed to systematically review the CSF immunological findings in schizophrenia spectrum and affective disorders. We identified all studies investigating CSF inflammatory markers in persons with schizophrenia or affective disorders published prior to March 23, 2017 searching PubMed, CENTRAL, EMBASE, Psychinfo, and LILACS. Literature search, data extraction and bias assessment were performed by two independent reviewers. Meta-analyses with standardized mean difference (SMD) including 95% confidence intervals (CI) were performed on case-healthy control studies. We identified 112 CSF studies published between 1942-2016, and 32 case-healthy control studies could be included in meta-analyses. Studies varied regarding gender distribution, age, disease duration, treatment, investigated biomarkers, and whether recruitment happened consecutively or based on clinical indication. The CSF/serum albumin ratio was increased in schizophrenia (1 study [54 patients]; SMD = 0.71; 95% CI 0.33-1.09) and affective disorders (4 studies [298 patients]; SMD = 0.41; 95% CI 0.23-0.60, I2 = 0%), compared to healthy controls. Total CSF protein was elevated in both schizophrenia (3 studies [97 patients]; SMD = 0.41; 95% CI 0.15-0.67, I2 = 0%) and affective disorders (2 studies [53 patients]; SMD = 0.80; 95% CI 0.39-1.21, I2 = 0%). The IgG ratio was increased in schizophrenia (1 study [54 patients]; SMD = 0.68; 95% CI 0.30-1.06), whereas the IgG Albumin ratio was decreased (1 study [32 patients]; SMD = -0.62; 95% CI -1.13 to -0.12). Interleukin-6 (IL-6) levels (7 studies [230 patients]; SMD = 0.55; 95% CI 0.35-0.76; I2 = 1%) and IL-8 levels (3 studies [95 patients]; SMD = 0.46; 95% CI 0.17-0.75, I2 = 0%) were increased in schizophrenia but not significantly increased in affective disorders. Most of the remaining inflammatory markers were not significantly different compared to healthy controls in the meta-analyses. However, in the studies which did not include healthy controls, CSF abnormalities were more common, and two studies found CSF dependent re-diagnosis in 3.2-6%. Current findings suggest that schizophrenia and affective disorders may have CSF abnormalities including signs of blood-brain barrier impairment and inflammation. However, the available evidence does not allow any firm conclusion since all studies showed at least some degree of bias and vastly lacked inclusion of confounding factors. Moreover, only few studies investigated the same parameters with healthy controls and high-quality longitudinal CSF studies are lacking, including impact of psychotropic medications, lifestyle factors and potential benefits of anti-inflammatory treatment in subgroups with CSF inflammation.

Lifestyle Interventions for Weight Management in People with Serious Mental Illness: A Systematic Review with Meta-Analysis, Trial Sequential Analysis, and Meta-Regression Analysis Exploring the Mediators and Moderators of Treatment Effects.

BACKGROUND: Serious mental illness (SMI) reduces life expectancy, primarily due to somatic comorbidity linked to obesity. Meta-analyses have found beneficial effects of lifestyle interventions in people with SMI and recommended their implementation to manage obesity. OBJECTIVE: The objective of this systematic review was to assess the benefits and harms of individualized lifestyle interventions for weight in people diagnosed with SMI and to explore potential mediators and moderators of the effect. METHODS: The protocol was registered at PROSPERO (CRD42016049093). Randomized clinical trials (RCTs) assessing the effect of individualized lifestyle interventions on weight management in people with SMI were included. Primary outcomes were differences in endpoint body mass index (BMI) and the proportion achieving clinically relevant weight loss (≥5%). Secondary outcomes included quality of life, cardiometabolic risk factors, and adverse effects. RESULTS: We included 41 RCTs (n = 4,267). All trials were at high risk of bias according to the Cochrane Handbook for Systematic Reviews of Interventions. The experimental interventions reduced the mean difference in BMI by -0.63 kg/m2 (95% confidence interval [CI] = -1.02 to -0.23; p = 0.002; I2 = 70.7%) compared to the control groups. At postintervention follow-up (17 RCTs), the effect size remained similar but was no longer significant (BMI = -0.63 kg/m2; 95% CI = -1.30 to 0.04; p = 0.07; I2 = 48.8%). The risk ratio for losing ≥5% of baseline weight was 1.51 (95% CI = 1.07-2.13; p = 0.02) compared to the control groups. GRADE showed very low or low quality of evidence. CONCLUSION: There is a statistically significant, but clinically insignificant, mean effect of individualized lifestyle interventions for weight reduction in people with SMI.

Hyperprolactinemia and the Association with All-Cause Mortality and Cardiovascular Mortality.

Hyperprolactinemia has been suspected to increase mortality risk, but the available data are conflicting. The objective of this study was to estimate the association between hyperprolactinemia and all-cause and cardiovascular mortality among patients referred for assessment of prolactin. For this study, adults with no prio pituitary disease who underwent prolactin assessment at 3 university Hospitals in Denmark between 2001 and 2011 were included in a retrospective cohort study. A total of 3 633 patients with a median follow-up time of 5.3 years (IQR 2.7-5.7) were included. Mean (SD) age 39.7 (15.5) years and 78% female. 373/3 633 (10.3%) had hyperprolactinemia and during follow-up 330/3 633 (9.1%) patients died of any cause, and 113/3 633 (3.1%) patients died of cardiovascular causes. In males, hyperprolactinemia was associated with age-adjusted incidence rate ratio (IRR) of 1.86 for all-cause mortality (95% CI 1.22-2.82) and 2.55 (95% CI 1.43-4.55) for cardiovascular mortality. The IRR for all-cause mortality was reduced to 1.37 (0.90-2.08) when adjusted for the use of antipsychotic medication. The association between hyperprolactinemia and cardiovascular mortality remained after adjusting for confounders, for example, chronic renal failure, diabetes, and antipsychotic medication. In females, hyperprolactinemia was not associated with all-cause mortality (IRR 1.45; CI 0.86-2.47) or cardiovascular mortality (IRR 0.58; CI 0.14-2.39). In conclusion, hyperprolactinemia was associated with increased cardiovascular mortality in male patients. This association was not found in female patients. Focus on increased cardiovascular risk in males with hyperprolactinemia is warranted.

Selective serotonin reuptake inhibitors versus placebo in patients with major depressive disorder. A systematic review with meta-analysis and Trial Sequential Analysis.

BACKGROUND: The evidence on selective serotonin reuptake inhibitors (SSRIs) for major depressive disorder is unclear. METHODS: Our objective was to conduct a systematic review assessing the effects of SSRIs versus placebo, 'active' placebo, or no intervention in adult participants with major depressive disorder. We searched for eligible randomised clinical trials in The Cochrane Library's CENTRAL, PubMed, EMBASE, PsycLIT, PsycINFO, Science Citation Index Expanded, clinical trial registers of Europe and USA, websites of pharmaceutical companies, the U.S. Food and Drug Administration (FDA), and the European Medicines Agency until January 2016. All data were extracted by at least two independent investigators. We used Cochrane systematic review methodology, Trial Sequential Analysis, and calculation of Bayes factor. An eight-step procedure was followed to assess if thresholds for statistical and clinical significance were crossed. Primary outcomes were reduction of depressive symptoms, remission, and adverse events. Secondary outcomes were suicides, suicide attempts, suicide ideation, and quality of life. RESULTS: A total of 131 randomised placebo-controlled trials enrolling a total of 27,422 participants were included. None of the trials used 'active' placebo or no intervention as control intervention. All trials had high risk of bias. SSRIs significantly reduced the Hamilton Depression Rating Scale (HDRS) at end of treatment (mean difference -1.94 HDRS points; 95% CI -2.50 to -1.37; P < 0.00001; 49 trials; Trial Sequential Analysis-adjusted CI -2.70 to -1.18); Bayes factor below predefined threshold (2.01*10-23). The effect estimate, however, was below our predefined threshold for clinical significance of 3 HDRS points. SSRIs significantly decreased the risk of no remission (RR 0.88; 95% CI 0.84 to 0.91; P < 0.00001; 34 trials; Trial Sequential Analysis adjusted CI 0.83 to 0.92); Bayes factor (1426.81) did not confirm the effect). SSRIs significantly increased the risks of serious adverse events (OR 1.37; 95% CI 1.08 to 1.75; P = 0.009; 44 trials; Trial Sequential Analysis-adjusted CI 1.03 to 1.89). This corresponds to 31/1000 SSRI participants will experience a serious adverse event compared with 22/1000 control participants. SSRIs also significantly increased the number of non-serious adverse events. There were almost no data on suicidal behaviour, quality of life, and long-term effects. CONCLUSIONS: SSRIs might have statistically significant effects on depressive symptoms, but all trials were at high risk of bias and the clinical significance seems questionable. SSRIs significantly increase the risk of both serious and non-serious adverse events. The potential small beneficial effects seem to be outweighed by harmful effects.

Chronic psychological stress seems associated with elements of the metabolic syndrome in patients with ischaemic heart disease.

BACKGROUND AND OBJECTIVES: Chronic psychological stress, the metabolic syndrome (MS) and ischaemic heart disease (IHD) seem closely connected. In this study, we evaluate the association between chronic stress and elements of MS in patients with stable IHD. DESIGN: Cross-sectional cohort study. METHODS: Three hundred and fifty patients with stable IHD were included. Chronic stress was evaluated by the two questionnaires, Major Depression Inventory (MDI) and the psychological wellbeing index WHO-5, as well as by Pressure Pain Sensitivity (PPS), a physiological measure of hyperalgesia at the sternum known to be associated to elements of the chronic stress syndrome. Elements of MS were evaluated by dual-energy X-ray absorptiometry, body weight, HOMA-IR and blood lipids. RESULTS: Depressive symptoms were associated with a high percentage of body fat (ß = 0.179, p = .001), and high level of triglycerides (ß = 0.150, p = .007). Low psychological wellbeing was associated with a high percentage of body fat (ß = -0.165, p = .002) and low level of HDL cholesterol (ß = 0.128, p = .024). Chronic stress measured by PPS was associated with a high percentage body fat (ß = 0.327, p < .001), low body weight (ß = -0.218, p < .001) and low HDL-cholesterol (ß = -0.137, p = .013). Adjusting for several life style factors did not change these results. CONCLUSIONS: In patients with stable IHD, different measures of chronic psychological stress seem associated with a high percentage of body fat and adverse blood lipids independent of several lifestyle factors.

Association analyses of depression and genes in the hypothalamus-pituitary-adrenal axis.

OBJECTIVE: Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has been reported in depression. The aim was to investigate the potential association between depression and seven genes regulating or interfering with the HPA axis, including the gene encoding angiotensin converting enzyme (ACE). METHODS: In total, 78 single nucleotide polymorphisms (SNPs) and one insertion/deletion polymorphism were genotyped. The study included 408 individuals with depression and 289 controls. In a subset of cases, the interaction between genetic variants and stressful life events (SLEs) was investigated. RESULTS: After quality control, 68 genetic variants were left for analyses. Four of nine variants within ACE were nominally associated with depression and a gene-wise association was likewise observed. However, none of the SNPs located within AVP, CRH, CRHR1, CRHR2, FKBP5 or NC3C1 were associated with depression. One nominally significant interaction, most likely due to chance, was identified. CONCLUSION: The results indicate that ACE could be a potential candidate gene for depression.

EFFECTIVENESS OF DIALECTICAL BEHAVIOR THERAPY VERSUS COLLABORATIVE ASSESSMENT AND MANAGEMENT OF SUICIDALITY TREATMENT FOR REDUCTION OF SELF-HARM IN ADULTS WITH BORDERLINE PERSONALITY TRAITS AND DISORDER-A RANDOMIZED OBSERVER-BLINDED CLINICAL TRIAL.

BACKGROUND: Many psychological treatments have shown effect on reducing self-harm in adults with borderline personality disorder. There is a need of brief psychotherapeutical treatment alternative for suicide prevention in specialized outpatient clinics. METHODS/DESIGN: The DiaS trial was designed as a pragmatic single-center, two-armed, parallel-group observer-blinded, randomized clinical superiority trial. The participants had at least two criteria from the borderline personality disorder diagnosis and a recent suicide attempt (within a month). The participants were offered 16 weeks of dialectical behavior therapy (DBT) versus up to 16 weeks of collaborative assessment and management of suicidality (CAMS) treatment. The primary composite outcome was the number of participants with a new self-harm (nonsuicidal self-injury [NSSI] or suicide attempt) at week 28 from baseline. Other exploratory outcomes were: severity of borderline symptoms, depressive symptoms, hopelessness, suicide ideation, and self-esteem. RESULTS: At 28 weeks, the number of participants with new self-harm in the DBT group was 21 of 57 (36.8%) versus 12 of 51 (23.5%) in the CAMS treatment (OR: 1.90; 95% CI: 0.80-4.40; P = .14). When assessing the effect of DBT versus CAMS treatment on the individual components of the primary outcome, we observed no significant differences in the number of NSSI (OR: 1.60; 95% CI: 0.70-3.90; P = .31) or number of attempted suicides (OR: 2.24; 95% CI: 0.80-7.50; P = .12). CONCLUSION: In adults with borderline personality traits and disorder and a recent suicide attempt, DBT does not seem superior compared with CAMS for reduction of number of self-harm or suicide attempts. However, further randomized clinical trials may be needed.

Sodium-glucose cotransporter (SGLT) 2 inhibitors for prevention or delay of type 2 diabetes mellitus and its associated complications in people at risk for the development of type 2 diabetes mellitus.

BACKGROUND: Sodium-glucose cotransporter (SGLT) 2 inhibitors were recently approved as glucose-lowering interventions in people with type 2 diabetes mellitus (T2DM). Potential beneficial or harmful effects of SGLT 2 inhibitors in people at risk for the development of T2DM are unknown. OBJECTIVES: To assess the effects of SGLT 2 inhibitors focusing on the prevention or delay of T2DM and its associated complications in people with impaired glucose tolerance, impaired fasting blood glucose or moderately elevated glycosylated haemoglobin A1c (HbA1c) or any combination of these. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PubMed, EMBASE, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and reference lists of systematic reviews, articles and health technology assessment reports. We asked investigators of ongoing for information about additional trials. The date of the last search of all databases was January 2016. SELECTION CRITERIA: Randomised controlled trials (RCTs) of any duration comparing SGLT 2 inhibitors with any glucose-lowering intervention, behaviour-changing intervention, placebo or no intervention in people with impaired fasting glucose, impaired glucose tolerance, moderately elevated HbA1c or combinations of these. DATA COLLECTION AND ANALYSIS: Two review authors read all abstracts, assessed quality and extracted data independently. We resolved discrepancies by consensus or the involvement of a third author. MAIN RESULTS: We could not include any RCT in this systematic review. One trial was published in two abstracts, but did not provide separate information of the participants with impaired glucose tolerance, impaired fasting glucose or both. We identified two ongoing trials, both evaluating the effects of dapagliflozin (and metformin) in people at risk for the development of type 2 diabetes and a follow-up of 24 to 26 weeks. Both trials will mainly report on surrogate outcome measures with some data on adverse effects and health-related quality of life. AUTHORS' CONCLUSIONS: Due to lack of data it is not possible to conclude whether SGLT 2 inhibitors prevent or delay the diagnosis of T2DM and its associated complications.
