Summary

• Stress Dose Hydrocortisone is the extra dose of corticoids.
• There is controversy about its use in various conditions.
• The common recommendation is mostly for adrenal insufficiency and septic shock.
• The use of stress dose is proven by clinical data, however, results are controversial.
• The dose and timing of dosages may vary from patient to patient.

Introduction:

Stress dose hydrocortisone is a life-saving intervention for patients with adrenal insufficiency who are undergoing physiological stress. It is essential for healthcare providers to stay updated on the latest guidelines and recommendations for stress dose hydrocortisone, especially in 2023, when the COVID-19 pandemic and its variants pose new challenges and uncertainties.

In this article, we will cover the basics of stress dose hydrocortisone, the latest guidelines for 2023, the rationale behind the current recommendations, the challenges and controversies surrounding stress dose hydrocortisone, the practical implications for healthcare providers, and the future directions for research and innovation.

What is Stress Dose Hydrocortisone?

Stress dose hydrocortisone is a concept/term used to describe the administration of extra hydrocortisone to patients with adrenal insufficiency who are facing situations of physical or emotional stress, such as illness, injury, surgery, or pregnancy. The purpose of stress dose hydrocortisone is to imitate the normal response of the adrenal glands.

Our adrenal glands produce more cortisol in times of stress to help the body cope. Adrenal insufficiency is a condition where the adrenal glands do not produce enough cortisol required for normal functioning of the body. Therefore, Patients with adrenal insufficiency require daily replacement therapy with glucocorticoids to maintain normal homeostasis.

However, during periods of physiological stress, such as surgery, trauma, infection, or fever, the normal replacement dose of glucocorticoids may not be sufficient to prevent an adrenal crisis, which is a life-threatening condition characterized by hypotension, shock, and multi-organ failure. Therefore, patients with adrenal insufficiency need to receive even high dose of hydrocortisone than usual to prevent or treat an adrenal crisis. The extra dose is known as Stress dose hydrocortisone, and it compensates the need of additional cortisol in those people.

History of Stress Dose Hydrocortisone

The idea of stress dose hydrocortisone dates back to the 1950s. Since its first use, various protocols and regimens have been proposed based on different assumptions and evidence. However, there is still no consensus on the optimal dose, duration, and mode of administration of stress dose hydrocortisone, and the practice varies widely among different settings and specialties.

The Latest Guidelines About Stress Dose Hydrocortisone for 2023

The latest guidelines for stress dose hydrocortisone were published by the Endocrine Society, the American Association of Clinical Endocrinologists, and the European Society of Endocrinology. These guidelines are based on a systematic review and meta-analysis of the available literature, as well as expert consensus and clinical experience.

The guidelines recommend different dosages of stress dose hydrocortisone for patients with adrenal insufficiency. You can find dosing details here.

How Does Stress Dose Hydrocortisone Work?

The rationale is based on the physiological role of cortisol in the human body. Cortisol is a steroid hormone that regulates various metabolic, immune, and cardiovascular functions. Cortisol also modulates the stress response, by enhancing the relevant part of nervous system nervous system. During stress conditions, it increases blood pressure, heart rate, and blood glucose and suppresses inflammation and immunity.

Under normal circumstances, the secretion of cortisol is regulated by a negative feedback loop involving the hypothalamus, the pituitary gland, and the adrenal glands. The hypothalamus releases a chemical CRH, which stimulates the pituitary gland to release another hormone, ACTH, which in turn stimulates the adrenal glands to produce cortisol. Cortisol then inhibits the release of CRH and ACTH, maintaining a balanced level of cortisol in the blood.

However, during periods of physiological stress, the hypothalamic-pituitary-adrenal (HPA) axis is activated, resulting in a surge of cortisol secretion. This is an adaptive response that helps the body cope with the stressor by mobilizing energy, increasing blood flow, and suppressing inflammation and infection. The HPA axis then returns to its baseline state once the stress is resolved.

Patients with adrenal insufficiency, however, are unable to mount a sufficient cortisol response to stress, due to the impaired function of the adrenal glands or the pituitary gland. This puts them at risk of developing an adrenal crisis, which is a medical emergency that can lead to death if not treated promptly. Therefore, patients with adrenal insufficiency need to receive stress dose to compensate for the lack of endogenous cortisol production and to prevent or treat an adrenal crisis.

A Review of Clinical Studies

The current guidelines for stress dose hydrocortisone are supported by several studies that have demonstrated the benefits and safety of stress dose hydrocortisone in patients with adrenal insufficiency. The evidence comes from various sources, including observational studies, randomized controlled trials, meta-analyses, and systematic reviews. However, the quality and quantity of the evidence are limited and heterogeneous, and the results are often conflicting or inconclusive.

Some studies suggest that it can improve stable blood flow in the body and lower mortality rates in patients with adrenal insufficiency and septic shock. Other studies suggest that stress dose hydrocortisone can reduce the incidence and severity of postoperative nausea and vomiting and improve wound healing and recovery in patients undergoing surgery. However, some studies also suggest that stress dose hydrocortisone may have no benefit or even harm in certain situations, such as traumatic brain injury, acute respiratory distress syndrome, or cushing disease.

Challenges and Controversies

Despite the evidence and consensus for stress dose hydrocortisone, there are still some challenges and controversies that need to be addressed and clarified. Some of the potential issues with stress dose hydrocortisone administration include

• The difficulty of defining and identifying stress in patients with adrenal insufficiency, as different stressors may have different effects on the HPA axis, and different patients may have different thresholds and perceptions of stress. There is no clear consensus on what constitutes a minor, moderate, or major stress and how to adjust the dose and duration accordingly.
• The variability of the dose and duration of stress dose hydrocortisone, as there is no one-size-fits-all approach, and the optimal dose and duration may depend on the individual patient’s condition, response, and preference.
• The risk of over-treatment or under-treatment with stress dose hydrocortisone, as both can have adverse consequences, such as increased morbidity, mortality, infection, or osteoporosis.
• The lack of awareness and education among patients and healthcare providers about stress dose hydrocortisone, as many patients and healthcare providers may not be familiar with the indications, dosage, and administration of stress dose hydrocortisone, or may have misconceptions or doubts about its efficacy and safety. Some patients may not carry an emergency injection kit or a medical alert bracelet or card, or may not know when and how to use them.

Conclusion

Stress dose hydrocortisone is a vital intervention for patients with adrenal insufficiency who are undergoing physiological stress. It is essential for healthcare providers to stay updated on the latest guidelines and recommendations for stress dose hydrocortisone, especially in 2023, when the COVID-19 pandemic and its variants pose new challenges and uncertainties.
