Background
- 95% of cases due to deficiency of 21-hydroxylase
- Leads to cortisol deficiency, aldosterone deficiency, virilization
- Patients present during 2nd-5th week of life in crisis
Clinical features/evaluation
- Patient presents in 2nd week of life in crisis
- Lethargy, irritability, poor feeding, vomiting, dehydration, shock
- Salt-wasting
- Virilization
Work-Up
- Bedside glucose
- Chemistry
- Hyponatremia
- Hyperkalemia - rarely causes cardiac dysfunction
Differential Diagnosis
- Adrenal salt-wasting crisis
Sick Neonate
THE MISFITS [1]
- Trauma
- Heart
- Congenital heart disease
- Hypovolemia
- Endocrine
- Metabolic
- Sodium
- Calcium
- Glucose
- Inborn errors of metabolism
- Seizure
- Formula / feeding problems
- Intestinal Disasters
- Toxin
- Sepsis
Management
- NS 10-20cc/kg bolus
- Steroid replacement
- Neonates: Hydrocortisone 25mg IV/IO
- Hyperkalemia
- Do NOT give insulin/glucose (may lead to profound hypoglycemia)
- NS and hydrocortisone are usually sufficient
- May add calcium gluconate if symptomatic
