Towards the tailoring of glucocorticoid replacement in adrenal insufficiency: the Italian Society of Endocrinology Expert Opinion.

2020

Context: Glucocorticoid (GC) replacement therapy in patients with adrenal insufficiency (AI) is life saving. After over 50 years of conventional GC treatment, novel formulations are now entering routine clinical practice. Methods: Given the spectrum of medications currently available and new insights into the understanding of AI, the authors reviewed relevant medical literature with emphasis on original studies, prospective observational data and randomized controlled trials performed in the past 35 years. The Expert Opinion of a panel of selected endocrinologists was sought to answer specific clinical questions. The objective was to provide an evidence-supported guide, for the use of GC in…

Use of corticosteroids and immunosuppressive drugs in inflammatory bowel disease: Clinical practice guidelines of the Italian Group for the Study of …

2017

Abstract The two main forms of intestinal bowel disease, namely ulcerative colitis and Crohn’s disease, are not curable but can be controlled by various medical therapies. The Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) has prepared clinical practice guidelines to help physicians prescribe corticosteroids and immunosuppressive drugs for these patients. The guidelines consider therapies that induce remission in patients with active disease as well as treatment regimens that maintain remission. These guidelines complement already existing guidelines from IG-IBD on the use of biological drugs in patients with inflammatory bowel diseases.

Phosphodiesterase-4 inhibition improves corticosteroid insensitivity in pulmonary endothelial cells under oxidative stress.

2012

Several clinical studies have shown that smoking in asthmatics and chronic obstructive pulmonary disease patients is closely associated with corticosteroid refractoriness. In this work, we have analyzed glucocorticoid insensitivity in human pulmonary artery endothelial cells (HPAECs) under cigarette smoke extract (CSE) exposure as well as the possible additive effects of the combination therapy with a phosphodiesterase (PDE)-4 inhibitor. Interleukin (IL)-8 was measured in cell supernatants by ELISA. Histone deacetylase (HDAC), histone acetylase (HAT), and intracellular cAMP levels were measured by colorimetric assays and enzyme immunoassay, respectively. PDE4 isotypes and glucocorticoid rec…

Multifocal disseminated lipoatrophy secondary to intravenous corticosteroid administration in a patient with adrenal insufficiency.

2002

Multifocal disseminated lesions of circumscribed lipoatrophy have not been described as an adverse reaction of intravenously applied drugs. A unique patient with adrenal insufficiency is reported who received corticosteroids intravenously and then had multiple lesions develop that were similar to focal lipoatrophy as known to occur secondary to faulty intradermal injections of corticosteroids.

Differential effects of MDMA and cocaine on inhibitory avoidance and object recognition tests in rodents.

2017

Introduction Drug addiction continues being a major public problem faced by modern societies with different social, health and legal consequences for the consumers. Consumption of psychostimulants, like cocaine or MDMA (known as ecstasy) are highly prevalent and cognitive and memory impairments have been related with the abuse of these drugs. Aim The aim of this work was to review the most important data of the literature in the last 10 years about the effects of cocaine and MDMA on inhibitory avoidance and object recognition tests in rodents. Development: The object recognition and the inhibitory avoidance tests are popular procedures used to assess different types of memory. We compare th…

Impact of increased mean arterial pressure on skin microcirculatory oxygenation in vasopressor-requiring septic patients: an interventional study

2019

Abstract Background Heterogeneity of microvascular blood flow leading to tissue hypoxia is a common finding in patients with septic shock. It may be related to suboptimal systemic perfusion pressure and lead to organ failure. Mapping of skin microcirculatory oxygen saturation and relative hemoglobin concentration using hyperspectral imaging allows to identify heterogeneity of perfusion and perform targeted measurement of oxygenation. We hypothesized that increasing mean arterial pressure would result in improved oxygenation in areas of the skin with most microvascular blood pooling. Methods We included adult patients admitted to the intensive care unit within the previous 24 h with sepsis a…

Hiperaldosteronismo primario por hiperplasia suprarrenal unilateral con resolución quirúrgica

2016

Unilateral adrenal hyperplasia is a rare cause of primary hyperaldosteronism (around a 3%) that has surgical treatment. A case of a patient with hypertension resistant to conventional therapy in treatment with 7 drugs who presented with primary hyperaldosteronism due to unilateral adrenal hyperplasia is presented. A left adrenalectomy was performed, and the patient had a good clinical response, with no need of any drug after 2 years of surgery. Unilateral adrenal hyperplasia is a different entity and it is not an asymmetric variant of the bilateral adrenal hyperplasia. In the study of patients with primary hyperaldosteronism and imaging tests with absence of adenoma is a diagnosis that must…

The neuronal efflux of noradrenaline: Dependency on sodium and facilitation by ouabain

1974

Rabbit hearts were isolated after pretreatment with the MAO inhibitor pargyline and with reserpine and were perfused with 200 ng/ml noradrenaline for 1 h. During the subsequent wash-out with an amine-free solution for 2 h, the neuronal efflux of noradrenaline declined mono-exponentially with a mean halftime of 42 min. Both Na+-free solution and ouabain caused facilitation of the efflux which thereafter declined in a multi-exponential fashion. The maximum facilitation was reached after 3 min of Na+-free perfusion and 25 min after introduction of ouabain. The amount of exogenous noradrenaline accumulated in the heart was only partially released when the extracellular Na+-concentration was nor…
