Manipulation of Hydrocortisone Tablets Leads to Iatrogenic Cushing Syndrome in a 6-Year-Old Girl With CAH

Life With Classic Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency: Challenges and Burdens

CONTEXT

Congenital adrenal hyperplasia (CAH) is an autosomal recessive genetic condition requiring daily medication(s) and attention to details. In addition to daily medications and regular visits with healthcare providers, families may live with perpetual angst regarding unpredictable occurrences of acute adrenal insufficiency. Despite numerous barriers and challenges imposed by this chronic condition, caregivers and healthcare professionals can empower our patients to achieve a good quality of life.

EVIDENCE SYNTHESIS

CAH is a global condition for which access to health care widely varies depending on local resources. Major treatment aims include good health, good quality of life, and achievement of personal goals for affected persons. To achieve these aims, patients, caregivers, and healthcare professionals interact to promote health maintenance and encourage positive outcomes for individuals with CAH. This article describes aspects of daily living with CAH through the perspective of 1 family and their healthcare team living in the United States. A young adult patient, nurse educator, and physicians provide their perspectives regarding patient health care, general well-being, and safety emphasizing that patients with CAH can thrive. Nevertheless, remembering and recognizing that many individuals with CAH live in areas with limited resources and enduring sociocultural barriers is essential.

CONCLUSION

With access to knowledgeable healthcare providers, sufficient resources, and psychosocial support, "children with CAH can thrive and live normal lives." The future challenge is securing mechanisms to decrease the financial, sociocultural, and health access barriers in other communities throughout the world.

Future Directions in the Management of Classic Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency

CONTEXT

The traditional management of classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHD) is difficult and often suboptimal.

OBJECTIVE

To review improvements in the diagnosis and management of 21OHD.

DESIGN

Literature review, synthesis, and authors' experience.

SETTING

United States (2 centers).

PARTICIPANTS

Not applicable.

INTERVENTIONS

Not applicable.

MAIN OUTCOMES

Not applicable.

RESULTS

The 11-oxygenated androgens are abundant in 21OHD, and their measurement might improve diagnosis and medication titration. Several new treatments are under development.

CONCLUSION

Circadian delivery of hydrocortisone improves disease management of 21OHD compared to conventional glucocorticoids. Glucocorticoid-sparing therapies such as crinecerfont and atumelnant offer the potential for a block-and-replace strategy, with physiologic replacement dosing of hydrocortisone.

CLINICAL TRIAL REGISTRATION

None.

Utilization of the Drug-Polymer Solid Dispersion Obtained by Ball Milling as a Taste Masking Method in the Development of Orodispersible Minitablets with Hydrocortisone in Pediatric Doses

The objective of the conducted research was to design 2 mm orodispersible minitablets of pediatric doses of hydrocortisone (0.5 mg; 1.0 mg) with desirable pharmaceutical properties and eliminate the sensation of a bitter taste using preparation of solid dispersion by ball mill. Hydrocortisone was selected as the model substance, as it is widely utilized in the pediatric population. ODMTs were prepared by compression (preceded by granulation) in a traditional single-punch tablet machine and evaluated using pharmacopoeial tests, DSC, and FTIR analysis. The methods used to evaluate the effectiveness of the taste-masking effect included in vivo participation of healthy volunteers, in vitro drug dissolution and utilization of an analytical device-"electronic tongue". The research employed a preclinical animal model to preliminary investigate the bioequivalence of the designed drug dosage form in comparison to reference products. The study confirmed the possibility of manufacturing good-quality hydrocortisone ODMTs with a taste-masking effect owing to the incorporation of a solid dispersion in the tablet mass.

Practice Variation among Pediatric Endocrinologists in the Dosing of Glucocorticoids in Young Children with Congenital Adrenal Hyperplasia

A Pediatric Endocrine Society (PES) Drugs and Therapeutics Committee workgroup sought to determine the prescribing practices of pediatric endocrinologists when treating children <10 years of age with congenital adrenal hyperplasia (CAH). Our workgroup administered a 32-question online survey to PES members. There were 187 respondents (88.9% attending physicians), mostly from university-affiliated clinics (~80%). Ninety-eight percent of respondents prescribed the short-acting glucocorticoid hydrocortisone to treat young children, as per the Endocrine Society CAH Guidelines, although respondents also prescribed long-acting glucocorticoids such as prednisolone suspension (12%), prednisone tablets (9%), and prednisone suspension (6%). Ninety-seven percent of respondents indicated that they were likely/very likely to prescribe hydrocortisone in a thrice-daily regimen, as per CAH Guidelines, although 19% were also likely to follow a twice-daily regimen. To achieve smaller doses, using a pill-cutter was the most frequent method recommended by providers to manipulate tablets (87.2%), followed by dissolving tablets in water (25.7%) to create a daily batch (43.7%) and/or dissolving a tablet for each dose (64.6%). Thirty-one percent of providers use pharmacy-compounded hydrocortisone suspension to achieve doses of <2.5 mg. Our survey shows that practices among providers in the dosing of young children with CAH vary greatly and sometimes fall outside of the CAH Guidelines-specifically when attempting to deliver lower, age-appropriate hydrocortisone doses.

Interpretation of Steroid Biomarkers in 21-Hydroxylase Deficiency and Their Use in Disease Management

The most common form of congenital adrenal hyperplasia is 21-hydroxylase deficiency (21OHD), which in the classic (severe) form occurs in roughly 1:16 000 newborns worldwide. Lifelong treatment consists of replacing cortisol and aldosterone deficiencies, and supraphysiological dosing schedules are typically employed to simultaneously attenuate production of adrenal-derived androgens. Glucocorticoid titration in 21OHD is challenging as it must balance the consequences of androgen excess vs those from chronic high glucocorticoid exposure, which are further complicated by interindividual variability in cortisol kinetics and glucocorticoid sensitivity. Clinical assessment and biochemical parameters are both used to guide therapy, but the specific purpose and goals of each biomarker vary with age and clinical context. Here we review the approach to medication titration for children and adults with classic 21OHD, with an emphasis on how to interpret adrenal biomarker values in guiding this process. In parallel, we illustrate how an understanding of the pathophysiologic and pharmacologic principles can be used to avoid and to correct complications of this disease and consequences of its management using existing treatment options.

Depressive and anxiety disorders and antidepressant prescriptions among insured children and young adults with congenital adrenal hyperplasia in the United States

Background

Dysfunction in the hypothalamic-pituitary-adrenal axis has been associated with depressive and anxiety disorders. Little is known about the risk for these disorders among individuals with congenital adrenal hyperplasia (CAH), a form of primary adrenal insufficiency.

Objective

We investigated the prevalence of depressive and anxiety disorders and antidepressant prescriptions in two large healthcare databases of insured children, adolescents, and young adults with CAH in the United States.

Methods

We conducted a retrospective cohort study using administrative data from October 2015 through December 2019 for individuals aged 4-25 years enrolled in employer-sponsored or Medicaid health plans.

Results

Adjusting for age, the prevalence of depressive disorders [adjusted prevalence ratio (aPR) = 1.7, 95% confidence interval (CI): 1.4-2.0, p<0.001], anxiety disorders [aPR = 1.7, 95% CI: 1.4-1.9, p<0.001], and filled antidepressant prescriptions [aPR = 1.7, 95% CI: 1.4-2.0, p<0.001] was higher among privately insured youth with CAH as compared to their non-CAH peers. Prevalence estimates were also higher among publicly insured youth with CAH for depressive disorders [aPR = 2.3, 95% CI: 1.9-2.9, p<0.001], anxiety disorders [aPR = 2.0, 95% CI: 1.6-2.5, p<0.001], and filled antidepressant prescriptions [aPR = 2.5, 95% CI: 1.9-3.1, p<0.001] as compared to their non-CAH peers.

Conclusions

The elevated prevalence of depressive and anxiety disorders and antidepressant prescriptions among youth with CAH suggests that screening for symptoms of depression and anxiety among this population might be warranted.

Study on the Preparation Method of Quality-Assured In-Hospital Drug Formulation for Children-A Multi-Institutional Collaborative Study

The quality-assured preparation of crushed and diluted preparations for children is a challenge. In this study, a multicenter study was conducted to validate the preparation method for the quality assurance of baclofen powder, clonidine powder, and hydrocortisone powder prepared from tablets according to a previously established method. In-hospital preparations were prepared at five medical facilities under different crushing and mixing conditions. After storage in closed bottles, in-use bottles, and laminated paper for 120 days, ingredients stability, drug elution, and content uniformity after packaging were evaluated. All three ingredients were maintained at between 90% and 110% of their initial content for 120 days under packaging conditions of 25 ± 2 °C and 60 ± 5% relative humidity, with no change in dissolution in all formulations made at all five facilities. The content uniformity was also acceptable. The established method may contribute to quality-assured pediatric dosage form modification.

The Use of Special-Order Products in England between 2012-2020: An Insight into The Need for Point-of-Care Manufacturing

Point-of-care manufacturing such as 3D printing has recently received significant attention from regulatory bodies and the pharmaceutical industry. However, little information is available on the quantity of the most prescribed patient-specific items, their dosage form, and why they were required to be dispensed. In England, 'Specials' are unlicensed medicines formulated to meet the requirements of a specific prescription, prescribed if no suitable licensed alternative exists. This work aims to quantify and examine trends in the prescribing of 'Specials' in England during 2012-2020, using the NHS Business Services Authority (NHSBSA) database. Quarterly prescription data from NHSBSA for the top 500 'Specials' by quantity from 2012-2020 were compiled yearly. The changes in net ingredient cost, the number of items, British National Formulary (BNF) drug category, dosage form, and a potential reason for requiring a 'Special' were identified. In addition, the cost-per-unit was calculated for each category. The total spending on 'Specials' decreased by 62% from £109.2M in 2012 to £41.4M in 2020, primarily due to a 55.1% reduction in the number of 'Specials' items issued. The most frequently prescribed dosage form type of 'Special' was oral dosage forms (59.6% of all items in 2020) particularly oral liquids. The most common reason for prescribing a 'Special' was an inappropriate dosage form (74% of all 'Specials' in 2020). The total number of items dropped over the 8 years as commonly prescribed 'Specials' such as melatonin and cholecalciferol became licensed. In conclusion, the total spending on 'Specials' dropped from 2012-2020 primarily due to a reduction in the number of 'Specials' items issued and pricing change in the Drug tariff. Based on the current demand for 'special order' products, these findings are instrumental for formulation scientists to identify 'Special' formulations to design the next generation of extemporaneous medicine to be produced at the point of care.

Bone Age Maturation and Growth Outcomes in Young Children with CAH Treated with Hydrocortisone Suspension

Background

Young children with congenital adrenal hyperplasia (CAH) require small doses (0.1-1.25 mg) of hydrocortisone (HC) to control excess androgen production and avoid the negative effects of overtreatment. The smallest commercially available HC formulation, before the recent US Food and Drug Administration approval of HC granules, was a scored 5-mg tablet. The options to achieve small doses were limited to using a pharmacy-compounded suspension, which the CAH Clinical Practice Guidelines recommended against, or splitting tablets into quarters or eighths, or dissolving tablets into water.

Methods

Cross-sectional chart review of 130 children with classic CAH treated with tablets vs a pharmacy-compounded alcohol-free hydrocortisone suspension to compare growth, weight, skeletal maturation, total daily HC dose, and exposure over the first 4 years of life.

Results

No significant differences were found in height, weight, or body mass index z-scores at 4 years, and in predicted adult height, before or after adjusting for age at diagnosis and sex. Bone age z-scores averaged 2.8 SDs lower for patients on HC suspension compared with HC tablets (P < 0.001) after adjusting for age at diagnosis and sex. The suspension group received 30.4% lower (P > 0.001) average cumulative HC doses by their fourth birthday.

Conclusions

Our data indicate that treatment with alcohol-free HC suspension decreased androgen exposure as shown by lower bone age z-scores, allowed lower average and cumulative daily HC dose compared to HC tablets, and generated no significant differences in SDS in growth parameters in children with CAH at 4 years of age. Longitudinal studies of treating with smaller HC doses during childhood are needed.

Stability of Hydrocortisone in Oral Powder Form Compounded for Pediatric Patients in Japan

Hydrocortisone has been utilized in the management of adrenal insufficiency. For pediatric patients, the commercially available enteral form of hydrocortisone tablets (Cortoril^®) is administered in powder form after being compounded by a pharmacist. However, the stability and quality of compounded hydrocortisone powder have not been verified. In this study, we formulated a 20 mg/g oral hydrocortisone powder by adding lactose monohydrate to crushed and filtered hydrocortisone tablets and assessed the stability and physical properties of this compounded product in polycarbonate amber bottles or coated paper packages laminated with cellophane and polyethylene. Stability was examined over 120 days in three storage conditions: closed bottle, in-use bottle, and laminated paper. Drug dissolution and powder X-ray diffraction analysis were conducted to assess its physicochemical stabilities. Validated liquid chromatography-diode array detection was used to detect and quantify hydrocortisone and its degradation products. Although impurity B (cortisone) and G (hydrocortisone-21-aldehyde) were found after 120 days of storage, no crystallographic and dissolution changes were noted. Hydrocortisone content was maintained between 90% and 110% of initial contents for 120 days at 25 ± 2 °C and 60 ± 5% relative humidity in all packaging conditions.

Adrenal insufficiency updates in children

PURPOSE OF REVIEW

The current article will review the newest diagnostic tools, genetic causes, and treatment of adrenal insufficiency in children.

RECENT FINDINGS

It is common practice to perform an adrenocorticotropin hormone (ACTH) stimulation test when adrenal insufficiency is suspected. The indications for use of a high-dose or low-dose of synthetic ACTH in children have been refined. In addition, newer studies propose adding 15 and 30-min serum or salivary cortisol levels to the low-dose ACTH stimulation test to correctly identify adrenal insufficiency. Recent identification of genetic mutations in children with non-classic steroidogenic acute regulatory protein and other mutations associated with primary and secondary adrenal insufficiency have expanded the cause and pathophysiology of monogenic adrenal insufficiency. In addition, newer hydrocortisone formulations and delivery methods and medications to use in combination with hydrocortisone are being explored to improve treatment for children with adrenal insufficiency.

SUMMARY

Improved diagnostic aids, detection of newer genetic mutations, and better treatment options and delivery systems will help correctly identify and manage children with adrenal insufficiency to improve health outcomes and quality of life.
