Cushing’s Syndrome (CS) is associated with a severe myopathy mainly affecting type 2 muscle fibres, with a higher prevalence in male subjects. The excess of glucocorticoids (GC) levels represents the most common cause of myopathy due to an alteration of protein metabolism. The non-coding post-transcriptional gene regulators muscle-specific microRNAs (miRNA) control muscle development and differentiation but when dysregulated lead to skeletal muscle (SM) disorder. The aim ...

The treatment with dual release hydrocortisone in patients with adrenal insufficiency: correlation between change of the evening cortisol exposure time profile and change in metabolic profile, depression status and quality of life

Simeoli Chiara , Ferrigno Rosario , Pivonello Claudia , Auriemma Renata Simona , Negri Mariarosaria , Di Gennaro Gilda , Iacuaniello Davide , De Martino Maria Cristina , Colao Annamaria , Pivonello Rosario

Conventional glucocorticoids (CGCs) are unable to mimic physiological cortisol rhythm in adrenal insufficiency (AI), resulting in increased metabolic morbidity and impaired quality of life (QoL). Non-physiological cortisol pattern and elevated evening cortisol levels may be responsible for the increased risk of metabolic disorders observed in AI patients under CGCs. Once daily dual-release-hydrocortisone (DR-HC), which better reproduces physiological daily cortisol profile, si...

Potential role of vitamin D in restoring sensitivity to mTOR inhibitors in hepatocellular carcinoma (HCC): 1,25(OH)vitamin D (VitD) reverts everolimus (EVE) resistance in a hcc cell line

Pivonello Claudia , Provvisiero Donatella Paola , Negri Mariarosaria , Gennaro Gilda Di , de Angelis Cristina , Simeoli Chiara , Galdiero Giacomo , Martino Maria Cristina De , Colao Annamaria , Pivonello Rosario

HCC is a difficult-to-treat- cancer with poor prognosis. Despite EVOLVE-1 trial demonstrated that EVE did not improve overall survival in molecularly and clinically unselected patients with advanced sorafenib resistant HCC, in selected patients, the established antitumor effect of EVE could make this drug a potential adjuvant therapy. Unfortunately, the acquired EVE resistance due to the tumour adaptation to chronic drug use is a current challenge. VitD has been deemed as pote...

Improved evening and nocturnal cortisol exposure time profile in patients with adrenal insufficiency treated with dual release hydrocortisone: correlation with improvement in metabolic profile

Simeoli Chiara , Ferrigno Rosario , De Martino Maria Cristina , Auriemma Renata Simona , Pivonello Claudia , Negri Mariarosaria , Iacuaniello Davide , Di Gennaro Gilda , Colao Annamaria , Pivonello Rosario

Conventional glucocorticoids (GCs) are unable to mimic physiological cortisol rhythm in adrenal insufficiency (AI), with a significant impact on morbidity and mortality. Possible explanations are supra-physiological doses and impaired cortisol profile. In particular, elevated evening cortisol levels were related to glucose tolerance and insulin sensitivity alterations and visceral obesity. Once-daily-dual-release-hydrocortisone (OD-DR-HC), better reproducing the physiological ...

Potential role of the adrenolitic drug mitotane in the treatment of hepatocarcinoma (HCC): effect on cell proliferation in HCC cell lines

Pivonello Claudia , Provvisiero Donatella Paola , Negri Mariarosaria , Di Gennaro Gilda , De Angelis Cristina , Simeoli Chiara , Patalano Roberta , De Martino Maria Cristina , Colao Annamaria , Pivonello Rosario

HCC is one of the most common malignancies worldwide. Local approaches are generally preferred for patients whose disease is restricted to the liver. In patients with extrahepatic disease systemic therapy can be considered. Chemotherapy did not demonstrate convincing survival advantages in several trails for HCC patients. Presently, the kinase inhibitor sorafenib is the only approved systemic target therapy for the treatment of advanced HCC. Mitotane (dichlorodiphenildichloroe...

Potential role of vitamin D in restoring sensitivity to mTOR inhibitors in hepatocellular carcinoma (HCC): 1,25(OH)vitamin D (VITD) reverts everolimus (EVE) resistance in a HCC cell line

Pivonello Claudia , Provvisiero Donatella Paola , Negri Mariarosaria , Di Gennaro Gilda , De Angelis Cristina , Galdiero Giacomo , Simeoli Chiara , De Martino Maria Cristina , Colao Annamaria , Pivonello Rosario

HCC is a difficult-to-treat- cancer with poor prognosis. The recent EVOLVE-1 trial demonstrated that EVE did not improve overall survival in molecularly and clinically unselected patients with advanced HCC resistant to sorafenib treatment. In selected patients, the well-established antitumor effect of EVE could make this drug a potential adjuvant therapy. Unfortunately, the acquired resistance to this molecule due to the tumor adaptation to chronic drug use is a current challe...

Effect of the switch from conventional glucocorticoids to ‘dual release hydrocortisone' in adult patients with primary and secondary adrenal insufficiency: a 6-month multicentre study

Pivonello Rosario , Simeoli Chiara , Isidori Andrea M , Ciresi Alessandro , Savastano Silvia , Auriemma Renata S , Graziadio Chiara , Di Somma Carolina , Giordano Carla , Lenzi Andrea , Colao Annamaria

Adrenal insufficiency (AI) requires life-long glucocorticoid (GC) treatment, which is associated with an increased risk of metabolic syndrome (MS), probably due to cortisol overexposure for multiple drug daily doses, together with an impairment of quality of life (QoL). Moreover treatment compliance (TC) is reported to be suboptimal in AI patients. The current study aimed at investigating the impact of the switch from twice/thrice daily conventional GCs to once daily dual-rele...

The treatment with ‘dual release' hydrocortisone (DR-HC) in congenital adrenal hyperplasia: short-term (6 months) and long-term (12 months) follow-up after the switch from conventional glucocorticoids to DR-HC

Simeoli Chiara , De Martino Maria Cristina , Iacuaniello Davide , Mannarino Teresa , Cozzolino Alessia , De Leo Monica , Pivonello Claudia , Negri Mariarosaria , De Angelis Cristina , Colao Annamaria , Pivonello Rosario

In patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, life-long glucocorticoid (GC) treatment is often required to replace cortisol deficiency and to avoid the ACTH-dependent androgen levels increase. However, in these patients, the multiple daily doses required with conventional GCs can cause cortisol overexposure, leading to an increased risk of metabolic syndrome (MS), an impaired quality of life (QoL), and poor treatment compliance (TC). T...

The treatment with glucocorticoids in congenital adrenal hyperplasia: short- and long-term effects of the switch from conventional glucocorticoids to ‘dual release' hydrocortisone on metabolic and hormonal profile

Simeoli Chiara , Mannarino Teresa , De Martino Maria Cristina , Cozzolino Alessia , Iacuaniello Davide , De Leo Monica , Auriemma Renata S , Di Somma Carolina , Colao Annamaria , Pivonello Rosario

Life-long glucocorticoid (GC) treatment is needed in patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency in order to replace cortisol deficiency and to control ACTH and consequently androgen levels. Therefore, patients with CAH tend to have an increased risk of metabolic syndrome (MS), probably due to cortisol overexposure, caused by multiple daily doses of conventional GCs, unable to mimic cortisol circadian rhythm. The current study aimed at i...

Cortisol rhythm in patients with adrenal insufficiency switched from conventional glucocorticoids to dual release hydrocortisone: Impact on metabolic profile

Simeoli Chiara , Iacono Marina , Ferrigno Rosario , Negri Mariarosaria , Pivonello Claudia , Simona Auriemma Renata , De Martino Maria Cristina , Colao Annamaria , Pivonello Rosario

Background: Several evidences suggested that conventional glucocorticoids (CGCs) used as replacement treatment in adrenal insufficiency (AI) are inadequate to mimic physiological cortisol circadian rhythm (CCR), and that CCR disruption, represented by non-physiological pattern of peaks and troughs and elevated evening GC levels, might be responsible for the increased metabolic and, consequently, cardiovascular risk. It has been demonstrated that once daily dual-release-hydroco...
