Summary
Sepsis-induced adrenal insufficiency is a critical complication diagnosed via cortisol levels. Treatment with hydrocortisone and fludrocortisone is recommended for septic shock patients unresponsive to other therapies.
Area of Science:
- Endocrinology
- Infectious Disease
- Critical Care Medicine
Background:
- The hypothalamic-pituitary adrenal axis is vital for host defense during infection.
- Sepsis triggers cortisol release to modulate inflammatory responses, but factors like tissue damage or drug interactions can lead to adrenal insufficiency.
- Diagnosing sepsis-induced adrenal insufficiency in the ICU presents significant challenges.
Purpose of the Study:
- To review the role of the hypothalamic-pituitary adrenal axis in sepsis.
- To discuss diagnostic criteria for sepsis-induced adrenal insufficiency.
- To evaluate corticosteroid therapy for septic shock.
Main Methods:
- Review of current literature and clinical guidelines.
- Analysis of diagnostic criteria for adrenal insufficiency.
- Evaluation of evidence from randomized controlled trials on corticosteroid therapy.
Main Results:
- Sepsis-induced adrenal insufficiency is diagnosed by basal cortisol < 10 microg/dl or a < 9 microg/dl increment after corticotrophin stimulation.
- The diagnostic utility of salivary free cortisol requires further investigation.
- Corticosteroid therapy for septic shock remains debated, but evidence supports its use in specific cases.
Conclusions:
- Sepsis-induced adrenal insufficiency is linked to poor prognosis.
- Current guidelines recommend specific diagnostic thresholds for adrenal insufficiency in sepsis.
- A 7-day course of hydrocortisone (200 mg/day) and fludrocortisone (50 microg/day) is suggested for septic shock patients refractory to fluids and vasopressors.

01:27Adrenal Gland Disorders
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
01:29Acute Kidney Injury III: Clinical Manifestations
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
01:25Acute Inflammation III: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
01:29Acute Kidney Injury II: Pathophysiology
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
