Should all patients with adrenal insufficiency or a subgroup of patients with pre-diabetes be treated with dual-release hydrocortisone ?

Guarnotta et al. compare the effects of dual-release (DR) hydrocortisone 36 months' treatment in 13 patients with primary adrenal insufficiency and 36 with secondary adrenal insufficiency, compared to conventional glucocorticoid treatment. A retrospective evaluation was conducted on the effects of 36 months of DR hydrocortisone therapy on visceral adiposity, insulin secretion and insulin sensitivity. Forty-nine patients with adrenal insufficiency were recruited. This article is protected by copyright. All ...


Effects of different administration methods of hydrocortisone on blood glucose in patients with septic shock: a Meta-analysis.

To systematically evaluate the effect of different administration methods of hydrocortisone on blood glucose in patients with septic shock.

Improved salivary cortisol rhythm with dual-release hydrocortisone

The purpose of replacement therapy in adrenal insufficiency (AI) is mimicking endogenous cortisol levels as closely as possible: dual release hydrocortisone (DR-HC) has been introduced to replicate the circadian cortisol rhythm. Multiple daily saliva collections could be used to assess the cortisol rhythm during real life: our aim was to study the salivary cortisol profile in AI.


Dose response effects of postnatal hydrocortisone on growth and growth factors in the neonatal rat.

Hydrocortisone (HC), at different dosages, is used in critically ill newborns for lung stability, blood pressure support, and prevention of chronic lung disease (CLD). Its long-term effects on postnatal growth are not well studied. We hypothesized that early exposure to high doses of HC adversely affects growth, growth factors, metabolic hormones, and neurological outcomes, persisting in adulthood.

Effects of Glucocorticoid on the Eye Development in Guinea Pigs.

Glucocorticoid (GC) has been widely used in clinic. However, the effect of GC on normal and myopic development of eyes is still unknown. In this study, 3-week-old guinea pigs were randomly divided into four groups: No-Lens (control), GC+No-Lens, negative lens-induced myopia (LIM), and GC+LIM. To induce myopia, right eyes were covered with a -10 D lens in GC+LIM and LIM groups. GC+No-Lens and GC+LIM groups received intraperitoneal injections of hydrocortisone (10 mg/kg) once daily for 2 weeks, and then recei...

The effects of hydrocortisone on tight junction genes in an in vitro model of the human fallopian epithelial cells.

The tight junction between epithelial cells helps making connections in the fallopian tube and contributes to successful fertilization. Breaking the tight junction complex induces various diseases such as the EP. Previous studies have shown that glucocorticoids are effective in repairing and maintaining intercellular tight junctions in epithelial cells of the fallopian tube, although their mechanism is still unknown. This research is a genomic study of hydrocortisone's effect on epithelial cells of the fall...

Neural Correlates of Glucocorticoids Effects on Autobiographical Memory Retrieval in Healthy Women.

It is well known that elevated cortisol after stress or after exogenous administration impairs episodic memory retrieval including autobiographical memory (AM) retrieval. This impairment might be mediated by deactivation of a neural network associated with memory retrieval including the prefrontal cortex (PFC) and limbic structures. However, the neural underpinnings of these cortisol effects on AM retrieval have not been investigated yet. In this study, thirty-three healthy women received either placebo or ...

Hydrocortisone did not reduce mortality at 90 days in patients with septic shock.

Hydrocortisone plus fludrocortisone reduced mortality at 90 days in patients with septic shock.

Comparison between intra-articular platelet-rich plasma injection versus hydrocortisone with local anesthetic injections in temporomandibular disorders: A double-blind study.

Temperomandibular joint (TMJ) is subjected to many disorders commonly called Temperomandibular disorders (TMDs); such as TMJ hypermobility, ankylosis, internal derangement, degenerative joint disease. Internal derangement is characterized by abnormal relationship of articular disc to the condyle and disc to fossa. In past many non-invasive conservative treatment modalities were tried out for its treatment which are joint unloading, use of anti-inflammatory agents, physiotherapy etc. Now a days corticosteroi...

Comparison of the effects of pachymic acid, moronic acid and hydrocortisone on the polysome loading of RNAs in lipopolysaccharide-treated THP-1 macrophages.

We have proposed that analysis of ribosome-loaded mRNAs (i.e., the translatome) is useful for elucidation of pharmacological effects of phytocompounds in immune cells, regarding the involvement of post-transcriptional regulation mechanisms. In the present study, we compared the effects of pachymic acid from Poria cocos fungus and moronic acid from propolis with those of hydrocortisone on the translatomes of THP-1 macrophages exposed to bacterial lipopolysaccharide (LPS) to find clues to their biological eff...

A rare cause of neonatal hypoglycemia in two siblings: TBX19 gene mutation.

Congenital isolated adrenocorticotropic hormone (ACTH) deficiency (IAD) is a rarely seen disease characterized by low serum ACTH and cortisol levels accompanied by normal levels of the other anterior pituitary hormones. In these patients, severe hypoglycemia, convulsions, and prolonged cholestatic jaundice are expected findings in the neonatal period. In this paper, we present two siblings with TBX19 gene mutation. The first case was investigated at the age of 2 months for severe hypoglycemia, recurrent co...

Variations in the management of acute illness in children with congenital adrenal hyperplasia: An audit of three paediatric hospitals.

Episodes of acute adrenal insufficiency (AI)/adrenal crises (AC) are a serious consequence of congenital adrenal hyperplasia (CAH). This study aimed to assess morbidity from acute illness in CAH and identify factors associated with use of IV hydrocortisone, admission and diagnosis of an AC.

Smart gated magnetic silica mesoporous particles for targeted colon drug delivery: New approaches for inflammatory bowel diseases treatment.

Magnetic mesoporous silica microparticles were loaded with safranin O (S1) and with hydrocortisone (S2) and the outer surface functionalized with a bulky azo derivative bearing urea moieties. Aqueous suspensions of both solids at pH 7.4 showed negligible payload release whereas a marked delivery was observed in the presence of sodium dithionite due to the rupture of the azo bonds. Besides, a moderate cargo release was observed at acidic pH due to the hydrolysis of the urea bonds that linked the azo deriva...

Central adrenal insufficiency: open issues regarding diagnosis and glucocorticoid treatment.

Background Central adrenal insufficiency (CAI) is characterized by impaired adrenocorticotropin (ACTH) secretion because of a disease or injury to the hypothalamus or the pituitary, leading to a reduced cortisol production. CAI suspicion arises more frequently in patients with pituitary tumors, cranial irradiation/surgery/injury/infections, as well as after exogenous glucocorticoid withdrawal. Nevertheless, a late diagnosis is not uncommon because CAI may present with nonspecific signs or symptoms, as fatig...

Pharmacological stress impairs working memory performance and attenuates dorsolateral prefrontal cortex glutamate modulation.

Working memory processes are associated with the dorsolateral prefrontal cortex (dlPFC). Prior research using proton functional magnetic resonance spectroscopy (H fMRS) observed significant dlPFC glutamate modulation during letter 2-back performance, indicative of working memory-driven increase in excitatory neural activity. Acute stress has been shown to impair working memory performance. Herein, we quantified dlPFC glutamate modulation during working memory under placebo (oral lactose) and acute stress co...

An efficient biotransformation of progesterone into 11α-hydroxyprogesterone by Rhizopus microsporus var. oligosporus.

Rhizopus microsporus var. oligosporus is a fungus that belongs to the Mucoraceae family that is used for the preparation of some soy-fermented foods. Microbial biotransformation of progesterone by R. microsporus var. oligosporus afforded some monohydroxylated and dihydroxylated metabolites. The main product was purified using chromatographic methods and identified as 11α-hydroxyprogesterone on the basis of its spectroscopic features. Time course studies by high-performance thin-layer chromatography demonst...

Metabolic Syndrome in Hypopituitarism.

Prevalence of metabolic syndrome (MetS) and mortality rates from cardiovascular causes are increased in patients with hypopituitarism. Features of obesity, visceral adiposity, dyslipidemia, insulin resistance, and hypertension are common in these patients. Unreplaced growth hormone (GH) deficiency and inadequate replacement of other hormone insufficiencies may be responsible for the adverse body composition and metabolic profile associated with hypopituitarism. Recently, fatty liver disease was added to thi...

Patterns of Death in Patients with Sepsis and the Use of Hydrocortisone, Ascorbic Acid, and Thiamine to Prevent these Deaths.

In general, patients with sepsis die from the host response to the infecting pathogen rather than from the infecting pathogen itself. Four patterns of death have been identified in sepsis, namely vasoplegic shock, single-organ respiratory failure (acute respiratory distress syndrome [ARDS]), multi-system organ failure (MSOF), and persistent MSOF with ongoing inflammation and immunosuppression with recurrent infections (persistent inflammation-immunosuppression and catabolism syndrome [PICS]). To improve the...

Bioactive monoterpene indole alkaloids from Nauclea officinalis.

Two new monoterpene indole alkaloids, naucleaoffines A (1) and B (2), together with six known alkaloids (3-8), were isolated from the stems and leaves of Nauclea officinalis. The structures of 1 and 2 were elucidated by extensive spectroscopic methods and the known compounds were identified by comparisons with the data reported in literature. All isolated compounds were evaluated for their anti-inflammatory activities and anti-HIV-1 activities. Compounds 1-8 exhibited significant inhibitory activities on ni...

The patient with bacterial infection sequelae in the form of damage to cranial nerves (CN) III, IV, and VI was followed-up. He had exhibited clinical and radiographic signs of paranasal sinusitis. Prior to his physiotherapy, the patient received standard treatment with natural and synthetic antibiotics and steroids. After acute signs of infection resolved without any functional improvement, the patient was referred to a rehabilitation unit to undergo neuromuscular re-education of the paralyzed extraocular m...

Synthesis of new ent-labdane diterpene derivatives from andrographolide and evaluation of their anti-inflammatory activities.

Two series of andrographolide derivatives with nitrogen-containing heterocycles, phenols and aromatic acids as bioisostere moiety of lactone ring were synthesized. 8 from 18 tested compounds showed stronger inhibitory effect on LPS-induced NO production in RAW264.7 macrophage than hydrocortisone. Among them, compound 8m exhibited the most potent inhibition with IC of 3.38 ± 1.03 μM. The structure-activity relationships (SARs) suggested that the replacement of lactone ring with small-molecule phenols...

Adenoma mimicking hyponatremia of SIAD.

Hyponatremia is a common electrolyte disorder, with prevalence as high as 20% in inpatient settings. It is classified based on volume status, urine sodium and osmolality results. While this approach might help narrow down the differential diagnoses, it can leave other diagnoses unentertained. In this case, we report recurrent and refractory hyponatremia secondary to hypocortisolism due to non-functioning pituitary macroadenoma. Interestingly, urine studies mimicked syndrome of inappropriate antidiuresis, bu...

Salvage therapy for acute severe ulcerative colitis during pregnancy.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with an age of onset that affects young people during the peak of their reproductive years. Management of flares of disease during pregnancy can be complex and there are few case reports of pregnant women with acute severe ulcerative colitis (ASUC). We present the case of a 31-year-old pregnant woman who at 16 weeks gestation developed ASUC in the context of primary non-response to infliximab therapy. She subsequently underwent an emergency lap...

Bacterial CYP154C8 catalyzes carbon-carbon bond cleavage in steroids.

Here, we report the first bacterial cytochrome P450, CYP154C8, that catalyzes the C-C bond cleavage reaction of steroids. A major change in product distribution is observed with CYP154C8, when the reactions are supported by NADPH and spinach redox partners ferredoxin and ferredoxin reductase, compared with previously reported reactions supported by NADH and redox partners containing putidaredoxin and putidaredoxin reductase. The NMR-based structural elucidation of reaction products reveals 21-hydroxyprednis...
