Dual-release hydrocortisone improves hepatic steatosis in patients with secondary adrenal insufficiency: A real-life study

2019

Background:Conventional glucocorticoid treatment has a significant impact on liver in patients with adrenal insufficiency. Dual-release hydrocortisone (DR-HC) provides physiological cortisol exposure, leading to an improvement in anthropometric and metabolic parameters. We aimed to evaluate the effects of 12-month DR-HC treatment on the hepatic steatosis index (HSI), a validated surrogate index of hepatic steatosis, in patients with secondary adrenal insufficiency (SAI).Methods:A total of 45 patients with hypopituitarism, 22 with hypogonadism, hypothyroidism, ACTH, and GH deficiencies, and 23 with hypogonadism, hypothyroidism, and ACTH deficiency, on replacement therapy for all the pituitar…

Biochemical Aspects of Chick Embryo Retina Development: The Effects of Glucocorticoids

1989

In chick embryo retina during development, DNA synthesis and the activities of DNA polymerase, thymidine kinase, thymidylate synthetase, and ornithine decarboxylase (ODC) declined in parallel from day 7 to 12. The administration in ovo of hydrocortisone reduced significantly, particularly at 8-10 days of incubation, both DNA synthesis and the four enzyme activities tested. The effect was dose dependent, reaching the maximum with 50-100 nmol of hydrocortisone, 8-16 h after treatment. The highest inhibition was found for ODC activity (70%), followed by thymidine kinase activity (62%) and DNA synthesis (45%), whereas activities of DNA polymerase and thymidylate synthetase were reduced only by …

Risk Factors for Rate of Relapse and Effects of Steroid Maintenance Therapy in Patients With Autoimmune Pancreatitis: Systematic Review and Meta-anal…

2019

Background & Aims: Risk for relapse after induction of remission with steroid therapy has been studied extensively in patients with autoimmune pancreatitis (AIP), but findings have been equivocal. We performed a systematic review and meta-analysis to estimate the relapse rate of AIP after initial remission after steroid treatment and to identify factors associated with relapse. Methods: Three reviewers searched MEDLINE, SCOPUS, and EMBASE until July 2018 to identify studies on rate of relapse of AIP after induction of remission with steroid therapy. A pooled estimate was calculated using the DerSimonian and Laird method for a random-effects model. This study was conducted in accordance …

The use of topical corticosteroides in the treatment of oral lichen planus in Spain: A national survey

2017

Background Explore the treatment of oral lichen planus with topical corticosteroids by the healthcare professionals in Spain. Material and Methods A questionnaire targeted health professionals who treat OLP, in particular maxillofacial surgeons, dermatologist and dentist. The dissemination of the questionnaires was conducted through professional associations and dental and medical societies. The questionnaire was previously evaluated by means of a cognitive pre-test procedure to ensure that the questions were opportune and appropriate, understandable and acceptable among the professionals. Results Of the 890 questionnaires sent a total of 190 questionnaires were answered by 90 dentists, 60 …

Intravitreal dexamethasone implant for cystoid macular edema and inflammation after scleral buckling

2015

Purpose Cystoid macular edema may occur following scleral buckling and therefore deteriorate the visual outcome. Inflammation may be the major causative factor in the development of postoperative cystoid macular edema. This case demonstrates the effectiveness of a dexamethasone implant as a treatment after the onset of choroidal inflammation and cystoid macular edema 6 months following scleral buckling and having visual acuity restored. Methods A 59-year-old phakic woman treated with scleral buckling for macula-off retinal detachment presented 2 months after surgery with cystoid macular edema with choroidal inflammation. Optical coherence tomography and fluorescein angiography were performe…

Darstellung und Reaktionen von 2-Methylen-canrenon

1995

Ausgehend vom Mannich-Salz 1 des Aldosteronantagonisten Canrenon oder von 2-Methylen-canrenon (2) wurden die am A-Ring anellierten Hetero- und Carbocyclen 5, 6, 8–13 dargestellt. Mit den Verbindungen 2, 3, 4b, 5, 6b, 8 und 12 wurden Bindungsstudien am Estradiol-, Progesteron-, Androgen-, Glucocorticoid- und Mineralocorticoid-Rezeptor sowie an den Serumproteinen Sexualhormonbindendes Globulin (SHBG) und Corticosteroidbindendes Globulin (CBG) durchgefuhrt. Die relativen Bindungsaffinitaten lagen bei CBG unter 1%, in allen anderen Fallen niedriger als 0.01%. Synthesis and Reactions of 2-Methylene-canrenone Starting from the Mannich salt 1 of the aldosterone antagonist canrenone or from 2-methy…

PEST-domain-enriched tyrosine phosphatase and glucocorticoids as regulators of anaphylaxis in mice

2011

To cite this article: Obiri DD, Flink N, Maier JV, Neeb A, Maddalo D, Thiele W, Menon A, Stassen M, Kulkarni RA, Garabedian MJ, Barrios AM, Cato ACB. PEST-domain-enriched tyrosine phosphatase and glucocorticoids as regulators of anaphylaxis in mice. Allergy 2012; 67: 175–182. Abstract Background:  PEST-domain-enriched tyrosine phosphatase (PEP) is a protein tyrosine phosphatase exclusively expressed in hematopoietic cells. It is a potent negative regulator of T-cell receptor signalling that acts on receptor-coupled protein tyrosine kinases. PEST-domain-enriched tyrosine phosphatase is also expressed in mast cell and is positively regulated by glucocorticoids, but its function is unknown. In…

Cortisol suppression and hearing thresholds in tinnitus after low-dose dexamethasone challenge

2012

Abstract Background Tinnitus is a frequent, debilitating hearing disorder associated with severe emotional and psychological suffering. Although a link between stress and tinnitus has been widely recognized, the empirical evidence is scant. Our aims were to test for dysregulation of the stress-related hypothalamus-pituitary adrenal (HPA) axis in tinnitus and to examine ear sensitivity variations with cortisol manipulation. Methods Twenty-one tinnitus participants and 21 controls comparable in age, education, and overall health status but without tinnitus underwent basal cortisol assessments on three non-consecutive days and took 0.5 mg of dexamethasone (DEX) at 23:00 on the first day. Corti…

Prognostic Factors of Death in 151 Adults With Hemophagocytic Syndrome: Etiopathogenically Driven Analysis.

2018

Objective: To characterize the etiologies and clinical features at diagnosis of patients with hemophagocytic lymphohistiocytosis (HLH) and correlate these baseline features with survival using an etiopathogenically guided multivariable model. Patients and Methods: The Spanish Group of Autoimmune Diseases HLH Study Group, formed in 2013, is aimed at collecting adult patients with HLH diagnosed in internal medicine departments between January 3, 2013, and October 28, 2017. Results: The cohort consisted of 151 patients (91 men; mean age, 51.4 years). After a mean follow-up of 17 months (range, 1-142 months), 80 patients died. Time-to-event analyses for death identified a worse survival curve f…
