- BACKGROUND:Increased morbidity and mortality associated with conventional glucocorticoid replacement therapy for primary adrenal insufficiency (primary AI; estimated prevalence 93-140/million), secondary AI (estimated prevalence, 150-280/million, respectively) or congenital adrenal hyperplasia (estimated prevalence, approximately 65/million) may be due to the inability of typical glucocorticoid treatment regimens to reproduce the normal circadian profile of plasma cortisol. A once-daily modified-release formulation of hydrocortisone has been developed to provide a plasma cortisol profile that better mimics the daytime endogenous profile of cortisol. Here, we describe the protocol for the European Adrenal Insufficiency Registry (EU-AIR), an observational study to assess the long-term safety of modified-release hydrocortisone compared with conventional glucocorticoid replacement therapies in routine clinical practice (ClinicalTrials.gov identifier: NCT01661387).METHODS:Patients enrolled in EU-AIR have primary or secondary AI and are receiving either modified-release or conventional glucocorticoid replacement therapy. The primary endpoints of EU-AIR are the incidence of intercurrent illness, adrenal crisis and serious adverse events (SAEs), as well as the duration of SAEs and dose changes related to SAEs. Data relating to morbidity, mortality, adverse drug reactions, dosing and concomitant therapies will be collected. Patient diaries will record illness-related dose changes between visits. All decisions concerning medical care are made by the registry physician and patient. Enrolment is targeted at achieving 3600 patient-years of treatment (1800 patient-years per group) for the primary analysis, which is focused on determining the non-inferiority of once-daily modified-release replacement therapy compared with conventional glucocorticoid therapy.RESULTS:Recruitment began in August 2012 and, as of March 2014, 801 patients have been enrolled. Fifteen centres are participating in Germany, the UK and Sweden, with recruitment soon to be initiated in the Netherlands.CONCLUSIONS:EU-AIR will provide a unique opportunity not only to collect long-term safety data on a modified-release preparation of glucocorticoid but also to evaluate baseline data on conventional glucocorticoid replacement. Such data should help to improve the treatment of AI.

Journal article (peer-reviewed)abstract
- Objective: Oral once-daily dual-release hydrocortisone (DR-HC) replacement therapy was developed to provide a cortisol exposure-time profile that closely resembles the physiological cortisol profile. This study aimed to characterize single-dose pharmacokinetics (PK) of DR-HC 5-20 mg and assess intrasubject variability. Methods: Thirty-one healthy Japanese or non-Hispanic Caucasian volunteers aged 20-55 years participated in this randomized, open-label, PK study. Single doses of DR-HC 5, 15 (3 x 5), and 20 mg were administered orally after an overnight fast and suppression of endogenous cortisol secretion. After estimating the endogenous cortisol profile, PK of DR-HC over 24 h were evaluated to assess dose proportionality and impact of ethnicity. Plasma cortisol concentrations were analyzed using liquid chromatography-tandem mass spectrometry. PK parameters were calculated from individual cortisol concentration-time profiles. Results: DR-HC 20 mg provided higher than endogenous cortisol plasma concentrations 0-4 h post-dose but similar concentrations later in the profile. Cortisol concentrations and PK exposure parameters increased with increasing doses. Mean maximal serum concentration (C-max) was 82.0 and 178.1 ng/mL, while mean area under the concentration-time curve (AUC)(0-infinity) was 562.8 and 1180.8 h x ng/mL with DR-HC 5 and 20 mg respectively. Within-subject PK variability was low (<15%) for DR-HC 20 mg. All exposure PK parameters were less than dose proportional (slope < 1). PK differences between ethnicities were explained by body weight differences. Conclusions: DR-HC replacement resembles the daily normal cortisol profile. Within-subject day-to-day PK variability was low, underpinning the safety of DR-HC for replacement therapy. DR-HC PK were less than dose proportional - an important consideration when managing intercurrent illness in patients with adrenal insufficiency.

- Context and objectiveTreatment for adrenal insufficiency (AI) remains suboptimal. Despite glucocorticoid replacement, patients with AI have reduced life expectancy and quality of life. This study aimed to describe the spectrum of management of glucocorticoid replacement in patients with AI enrolled in the European Adrenal Insufficiency Registry (EU-AIR). Design, setting and patientsEU-AIR is a prospective, multinational, multicentre, observational study initiated in August 2012 to monitor the long-term safety of glucocorticoid replacement in routine clinical practice in Germany, the Netherlands, Sweden and the UK (ClinicalTrials.gov identifier: NCT01661387). This analysis included 1166 patients with primary and secondary AI (mean disease duration 16amp;lt;boldamp;gt;amp;lt;/boldamp;gt;1 11amp;lt;boldamp;gt;amp;lt;/boldamp;gt;6 years) receiving long-term glucocorticoid replacement therapy. Main outcome measureGlucocorticoid type, dose, frequency and treatment regimen were examined. ResultsMost patients (87amp;lt;boldamp;gt;amp;lt;/boldamp;gt;4%) were receiving hydrocortisone. The most common dose range, taken by 42amp;lt;boldamp;gt;amp;lt;/boldamp;gt;2% of patients, was 20 to amp;lt;25 mg/day; however, 12amp;lt;boldamp;gt;amp;lt;/boldamp;gt;6% were receiving doses of 30 mg/day. Hydrocortisone was being taken once daily by 5amp;lt;boldamp;gt;amp;lt;/boldamp;gt;5%, twice daily by 48amp;lt;boldamp;gt;amp;lt;/boldamp;gt;7%, three times daily by 43amp;lt;boldamp;gt;amp;lt;/boldamp;gt;6% and four times daily by 2amp;lt;boldamp;gt;amp;lt;/boldamp;gt;1%. Patients with primary AI received higher replacement doses than those with secondary AI (23amp;lt;boldamp;gt;amp;lt;/boldamp;gt;4 +/- 8amp;lt;boldamp;gt;amp;lt;/boldamp;gt;9 and 19amp;lt;boldamp;gt;amp;lt;/boldamp;gt;6 +/- 5amp;lt;boldamp;gt;amp;lt;/boldamp;gt;9 mg/day, respectively). Twenty-five different regimens were being used to deliver a daily hydrocortisone dose of 20 mg. ConclusionsWe have shown significant heterogeneity in the type, dose, frequency and timing of glucocorticoid replacement in real-world clinical practice. This reflects dose individualization based on patient symptoms and lifestyle in the absence of data supporting the optimal regimen.

- Objective: To investigate the long-term safety and tolerability of a once-daily, dual-release hydrocortisone (DR-HC) tablet as oral glucocorticoid replacement therapy in patients with primary adrenal insufficiency (AI).Design: Prospective, open-label, multicenter, 5-year extension study of DR-HC conducted at five university clinics in Sweden.Methods: Seventy-one adult patients diagnosed with primary AI who were receiving stable glucocorticoid replacement therapy were recruited. Safety and tolerability outcomes included adverse events (AEs), intercurrent illness episodes, laboratory parameters and vital signs. Quality of life (QoL) was evaluated using generic questionnaires.Results: Total DR-HC exposure was 328 patient-treatment years. Seventy patients reported 1060 AEs (323 per 100 patient-years); 85% were considered unrelated to DR-HC by the investigator. The most common AEs were nasopharyngitis (70%), fatigue (52%) and gastroenteritis (48%). Of 65 serious AEs reported by 32 patients (20 per 100 patient-years), four were considered to be possibly related to DR-HC: acute AI (n = 2), gastritis (n = 1) and syncope (n = 1). Two deaths were reported (fall from height and subarachnoid hemorrhage), both considered to be unrelated to DR-HC. From baseline to 5 years, intercurrent illness episodes remained relatively stable (mean 2.6-5.4 episodes per patient per year), fasting plasma glucose (0.7 mmol/L; P < 0.0001) and HDL cholesterol (0.2 mmol/L; P < 0.0001) increased and patient-/investigator-assessed tolerability improved. QoL total scores were unchanged but worsening physical functioning was recorded (P = 0.008).Conclusions: In the first prospective study evaluating the long-term safety of glucocorticoid replacement therapy in patients with primary AI, DR-HC was well tolerated with no safety concerns observed during 5-year treatment.

Journal article (peer-reviewed)abstract
- Objective: This study aimed to characterize the clinical and biochemical features of patients with primary (PAI) and secondary (SAI) adrenal insufficiency who developed adrenal crises (ACs) and estimate the incidence of ACs in these patients. Design: Retrospective case-control analysis of the European Adrenal Insufficiency Registry (EU-AIR; NCT01661387). Methods: Two thousand six hundred and ninety-four patients with AI (1054 PAI; 1640 SAI) enrolled in EU-AIR. Patients who developed >= 1 AC were matchd 1:3 with patients without ACs for age, sex and AI type. Data were collected at baseline and follow-up (mean +/- s.D.: PAI 3.2 +/- 1.7 years; SAI 2.9 +/- 1.7 years). Results: One hundred and forty-eight out of 2694 patients (5.5%; n = 84 PAI; n = 64 SAI) had an AC during the study: 6.53 (PAI) and 3.17 (SAI) ACs/100 patient-years. Of patients who experienced an AC, 16% (PAI) and 9.4% (SAI) experienced > 1 AC/year. The incidence of adverse events, infectious intercurrent illnesses and infectious serious adverse events were higher in patients with ACs than without ACs. No differences were observed in BMI, HbA1c, blood pressure and frequencies of diabetes mellitus or hypertension between subgroups (PAI and SAI, with and without ACs). At baseline, PAI patients with AC had higher serum potassium (4.3 +/- 0.5 vs 4.2 +/- 0.4 mmol/L; P = 0.03) and lower sodium (138.5 +/- 3.4 vs 139.7 +/- 2.9 mmol/L; P = 0.004) than patients without AC. At last observation, SAI patients with AC had higher hydrocortisone doses than patients without AC (11.9 +/- 5.1 vs 10.1 +/- 2.9 mg/m(2); P < 0.001). Conclusions: These results demonstrate that concomitant diseases and cardiovascular risk factors do not feature in the risk profile of AC; however, patients with AC had a higher incidence of infectious events.

Prednisolone is associated with a worse lipid profile than hydrocortisone in patients with adrenal insufficiency
- 2017

In: Endocrine Connections. - : BIOSCIENTIFICA LTD. - 2049-3614. ; 6:1
-
Journal article (peer-reviewed)abstract
- Objective: Prednisolone is used as glucocorticoid replacement therapy for adrenal insufficiency (AI). Recent data indicate that its use in AI is associated with low bone mineral density. Data on risk factors for cardiovascular disease in patients with AI treated with prednisolone are scarce, despite this condition being the predominant cause of excess mortality. We aimed to address this question using real-world data from the European Adrenal Insufficiency Registry (EU-AIR). Design/methods: EU-AIR, comprising of 19 centres across Germany, the Netherlands, Sweden and the UK, commenced enrolling patients with AI in August 2012. Patients receiving prednisolone (3-6 mg/day, n = 50) or hydrocortisone (15-30 mg/day, n = 909) were identified and grouped at a ratio of 1: 3 (prednisolone: hydrocortisone) by matching for gender, age, duration and type of disease. Data from baseline and follow-up visits were analysed. Data from patients with congenital adrenal hyperplasia were excluded. Results: Significantly higher mean +/- s. d. total (6.3 +/- 1.6 vs 5.4 +/- 1.1 mmol/L; P = 0.003) and low-density lipoprotein (LDL) cholesterol levels (3.9 +/- 1.4 vs 3.2 +/- 1.0 mmol/L; P = 0.013) were identified in 47 patients on prednisolone vs 141 receiving hydrocortisone at baseline and at follow-up (P = 0.005 and P = 0.006, respectively). HbA1c, high-density lipoprotein and triglyceride levels, body mass index, systolic and diastolic blood pressure and waist circumference were not significantly different. Conclusions: This is the first matched analysis of its kind. Significantly higher LDL levels in patients receiving prednisolone relative to hydrocortisone could predict a higher relative risk of cardiovascular disease in the former group.

- Patients with adrenal insufficiency (AI) (primary AI [PAI], secondary AI due to a pituitary disorder [PIT] and congenital adrenal hyperplasia [CAH]) have reduced life expectancy; however, the underlying explanation remains unknown.To evaluate characteristics, comorbidities, and hospitalizations in AI patients.Retrospective observational.Using a United States-based national payer database comprising of more than 108 million members, strict inclusion criteria including diagnostic codes and steroid prescription records were used to identify 10 383 adults with AI; 1014 with PAI, 8818 with PIT, and 551 with CAH. Patients were matched 1:1 to controls, based on age (±5 y), gender, insurance, and region and followed for more than 12 months.None.Demographic variables, comorbidities (diabetes mellitus [DM] types 1 and 2, depression, anxiety, hyperlipidemia, hypertension) and hospitalization incidence.Compared with controls, patients with AI had higher odds of DM, hypertension, hyperlipidaemia, depression, and anxiety, ranging from an odds ratio (OR) of 1.51 for hyperlipidaemia in PAI to 3.85 for DM in CAH. Odds of having DM (OR, 3.85; 95% confidence interval, 2.52-5.90) or anxiety (OR, 2.99; 95% confidence interval, 2.02-4.42) compared with controls were highest in CAH, whereas depression was highest in PAI and PIT (OR, 2.40 and 2.55). ORs of hyperlipidaemia and hypertension (OR, 1.98 and 2.24) were highest in the PIT cohort. Inpatient admissions were more frequent in PAI (4.64:1; P < .0001) and PIT (4.00:1; P < .0001) than controls; infection was the most common cause for admission.Patients with AI carry a significant metabolic and psychiatric burden, with higher risk of comorbidities and hospital admissions than matched controls.
