Metyrapone and osilodrostat are both steroidogenic inhibitors targeting the 11β-hydroxylase, however, their therapeutic effectiveness has not yet been directly compared. This study aimed to evaluate metyrapone and osilodrostat in the short-term therapy of CS. Methods Retrospective analysis of patients with endogenous CS treated with metyrapone or osilodrostat as monotherapy for at least 4 weeks. Main outcome measures were serum cortisol and 24h urinary free cortisol (UFC) at baseline (T0) and after 2 (T1), 4 (T2), and 12 weeks (T3) of therapy. Results 16 patients with endogenous CS were identified (pituitary n=7, adrenal n=4, ectopic CS n=5). Each 8 patients were treated with metyrapone and osilodrostat. Despite heterogeneity, both groups showed comparable mean UFC levels at T0 (metyrapone: 758 µg/24h vs osilodrostat: 817 µg/24h; p=0.93). From T0 to T1, the decrease of UFC was less pronounced under metyrapone than osilodrostat (-21.3\% vs -68.4\%; median daily drug dose: 1000 mg vs 4 mg). This tendency persisted at T2 (-37.3\% vs -50.1\%; median drug dose: 1250 mg vs 6 mg) while at T3 a decrease in UFC from T0 was more pronounced in the metyrapone group (-71.5\% vs -51.5\%; median dose 1250 mg vs 7 mg). Under osilodrostat, a QTc-interval prolongation was identified at T3 (mean 432 ms vs 455 ms). From T0 to T2, the number of antihypertensive drugs remained comparable under metyrapone and decreased under osilodrostat (n= -0.3 vs n= -1.0). Conclusion Although both drugs show comparable therapeutic efficacy, osilodrostat seems to reduce cortisol levels and to control blood pressure faster.}, language = {en} } @article{PerkovicAgarwalFiorettoetal.2016, author = {Perkovic, Vlado and Agarwal, Rajiv and Fioretto, Paola and Hemmelgarn, Brenda R. and Levin, Adeera and Thomas, Merlin C. and Wanner, Christoph and Kasiske, Bertram L. and Wheeler, David C. and Groop, Per-Henrik}, title = {Management of patients with diabetes and CKD: conclusions from a "Kidney Disease: Improving Global Outcomes" (KDIGO) controversies conference}, series = {Kidney International}, volume = {90}, journal = {Kidney International}, number = {6}, doi = {10.1016/j.kint.2016.09.010}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-186599}, pages = {1175-1183}, year = {2016}, abstract = {The prevalence of diabetes around the world has reached epidemic proportions and is projected to increase to 642 million people by 2040.

The presence of kidney disease is associated with a markedly elevated risk of cardiovascular disease and death in people with diabetes. Several new therapies and novel investigational agents targeting chronic kidney disease patients with diabetes are now under development.

In the 4/6 NX rats also the effect of the angiotensin receptor blocker, losartan, and the central sympatholyticum moxonidine was studied for two months. In serial brain sections Fos-immunoreactive neurons were localized and classified semiquantitatively. In 37 brain areas/nuclei several neurons with different functional properties were strongly affected in 4/6NX. It elicited a moderate to high Fos-activity in areas responsible for the monoaminergic innervation of the cerebral cortex, the limbic system, the thalamus and hypothalamus (e.g. noradrenergic neurons of the locus coeruleus, serotonergic neurons in dorsal raphe, histaminergic neurons in the tuberomamillary nucleus). Other monoaminergic cell groups (A5 noradrenaline, C1 adrenaline, medullary raphe serotonin neurons) and neurons in the hypothalamic paraventricular nucleus (innervating the sympathetic preganglionic neurons and affecting the peripheral sympathetic outflow) did not show Fos-activity. Stress- and pain-sensitive cortical/subcortical areas, neurons in the limbic system, the hypothalamus and the circumventricular organs were also affected by 4/6NX. Administration of losartan and more strongly moxonidine modulated most effects and particularly inhibited Fos-activity in locus coeruleus neurons. In conclusion, 4/6NX elicits high activity in central sympathetic, stress- and pain-related brain areas as well as in the limbic system, which can be ameliorated by losartan and particularly by moxonidine. These changes indicate a high sensitivity of CNS in initial stages of CKD which could be causative in clinical disturbances.}, language = {en} } @article{ZinmanInzucchiLachinetal.2014, author = {Zinman, Bernard and Inzucchi, Silvio E. and Lachin, John M. and Wanner, Christoph and Ferrari, Roberto and Fitchett, David and Bluhmki, Erich and Hantel, Stefan and Kempthorne-Rawson, Joan and Newman, Jennifer and Johansen, Odd Erik and Woerle, Hans-Juergen and Broedl, Uli C.}, title = {Rationale, design, and baseline characteristics of a randomized, placebo-controlled cardiovascular outcome trial of empagliflozin (EMPA-REG OUTCOME (TM))}, series = {Cardiovascular Diabetology}, volume = {13}, journal = {Cardiovascular Diabetology}, number = {102}, issn = {1475-2840}, doi = {10.1186/1475-2840-13-102}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-116036}, year = {2014}, abstract = {Background: Evidence concerning the importance of glucose lowering in the prevention of cardiovascular (CV) outcomes remains controversial. Given the multi-faceted pathogenesis of atherosclerosis in diabetes, it is likely that any intervention to mitigate this risk must address CV risk factors beyond glycemia alone. The SGLT-2 inhibitor empagliflozin improves glucose control, body weight and blood pressure when used as monotherapy or add-on to other antihyperglycemic agents in patients with type 2 diabetes. The aim of the ongoing EMPA-REG OUTCOME (TM) trial is to determine the long-term CV safety of empagliflozin, as well as investigating potential benefits on macro-/microvascular outcomes. Methods: Patients who were drug naive (HbA(1c) >= 7.0\% and <= 9.0\%), or on background glucose-lowering therapy (HbA(1c) >= 7.0\% and <= 10.0\%), and were at high risk of CV events, were randomized (1:1:1) and treated with empagliflozin 10 mg, empagliflozin 25 mg, or placebo (double blind, double dummy) superimposed upon the standard of care. The primary outcome is time to first occurrence of CV death, non-fatal myocardial infarction, or non-fatal stroke. CV events will be prospectively adjudicated by an independent Clinical Events Committee. The trial will continue until >= 691 confirmed primary outcome events have occurred, providing a power of 90\% to yield an upper limit of the adjusted 95\% CI for a hazard ratio of <1.3 with a one-sided a of 0.025, assuming equal risks between placebo and empagliflozin (both doses pooled). Hierarchical testing for superiority will follow for the primary outcome and key secondary outcomes (time to first occurrence of CV death, non-fatal myocardial infarction, non-fatal stroke or hospitalization for unstable angina pectoris) where non-inferiority is achieved. Results: Between Sept 2010 and April 2013, 592 clinical sites randomized and treated 7034 patients (41\% from Europe, 20\% from North America, and 19\% from Asia). At baseline, the mean age was 63 +/- 9 years, BMI 30.6 +/- 5.3 kg/m(2), HbA1c 8.1 +/- 0.8\%, and eGFR 74 +/- 21 ml/min/1.73 m(2). The study is expected to report in 2015. Discussion: EMPA REG OUTCOME (TM) will determine the CV safety of empagliflozin in a cohort of patients with type 2 diabetes and high CV risk, with the potential to show cardioprotection.}, language = {en} } @article{HaringGronroosNettletonetal.2014, author = {Haring, Bernhard and Gronroos, Noelle and Nettleton, Jennifer A. and Wyler von Ballmoos, Moritz C. and Selvin, Elizabeth and Alsonso, Alvaro}, title = {Dietary Protein Intake and Coronary Heart Disease in a Large Community Based Cohort: Results from the Atherosclerosis Risk in Communities (ARIC) Study}, doi = {10.1371/journal.pone.0109552}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-113570}, year = {2014}, abstract = {Background Prospective data examining the relationship between dietary protein intake and incident coronary heart disease (CHD) are inconclusive. Most evidence is derived from homogenous populations such as health professionals. Large community-based analyses in more diverse samples are lacking. Methods We studied the association of protein type and major dietary protein sources and risk for incident CHD in 12,066 middle-aged adults (aged 45-64 at baseline, 1987-1989) from four U.S. communities enrolled in the Atherosclerosis Risk in Communities (ARIC) Study who were free of diabetes mellitus and cardiovascular disease at baseline. Dietary protein intake was assessed at baseline and after 6 years of follow-up by food frequency questionnaire. Our primary outcome was adjudicated coronary heart disease events or deaths with following up through December 31, 2010. Cox proportional hazard models with multivariable adjustment were used for statistical analyses. Results During a median follow-up of 22 years, there were 1,147 CHD events. In multivariable analyses total, animal and vegetable protein were not associated with an increased risk for CHD before or after adjustment. In food group analyses of major dietary protein sources, protein intake from red and processed meat, dairy products, fish, nuts, eggs, and legumes were not significantly associated with CHD risk. The hazard ratios [with 95\% confidence intervals] for risk of CHD across quintiles of protein from poultry were 1.00 [ref], 0.83 [0.70-0.99], 0.93 [0.75-1.15], 0.88 [0.73-1.06], 0.79 [0.64-0.98], P for trend = 0.16). Replacement analyses evaluating the association of substituting one source of dietary protein for another or of decreasing protein intake at the expense of carbohydrates or total fats did not show any statistically significant association with CHD risk. Conclusion Based on a large community cohort we found no overall relationship between protein type and major dietary protein sources and risk for CHD.}, language = {en} }
