Treatment
Medical Care
- Glucocorticoid deficiency
- Careful replacement of glucocorticoids in patients with known adrenal insufficiency is critical to avoid an adrenal crisis and to allow for normal growth in children.
- Growth must be closely monitored because overtreatment with glucocorticoids impairs linear growth.
- Providing stress doses of hydrocortisone during illness or injury is also important.
- Every patient should always wear a medical alert bracelet or necklace and carry the emergency medical information card supplied with it.
- In adult patients, as well as those who have difficulty with compliance, replacing hydrocortisone with an equipotent dose of prednisone or dexamethasone is appropriate.
- Achalasia
- Achalasia is best managed with surgical correction.
- Monitoring patients for pulmonary complications (due to reflux and aspiration) and providing gastric acid reduction therapy in patients with symptomatic reflux after surgical intervention is important.
- Alacrima
- Alacrima is managed with regular application of topical lubricants and with punctal occlusion.
- Children may need to be frequently reminded to use artificial tears.
- Children must have an annual ophthalmologic evaluation.
Surgical Care
- The symptoms of alacrima improve with punctal occlusion. This procedure is only necessary when therapy with topical lubricants is unsuccessful because of poor compliance.
- The symptoms of lower esophageal sphincter spasm in patients with achalasia can be ameliorated partially with pneumatic dilatation. In patients who remain symptomatic after pneumatic dilatation, an anterior cardiomyotomy (modified Heller operation) may be performed. This surgical procedure involves directly cutting the muscles of the spastic sphincter. Both procedures have a risk of esophageal perforation and a high rate of postsurgical reflux.
- Patients with Allgrove syndrome who undergo surgery must be treated with stress doses of glucocorticoids in the perioperative period.
Consultations
- Ophthalmologist: A Schirmer test provides a semiquantitative measure of tearing. Other ophthalmologic testing, including slit lamp examination and fluorescein staining, is helpful in identifying patients with corneal pathology secondary to poor lacrimation.
- Neurologist: Neurologic tests highlight a myriad of neurologic and developmental issues. Palatopharyngeal incompetence, sensory impairment, ataxia, and muscle weakness are among the documented findings.
Diet
- Other than the diet changes mandated by the mechanical issues related to achalasia, no specific diet is indicated.
Activity
- In a subset of patients with autonomic disturbance, some activities may need to be limited because of problems with recurring orthostatic hypotension and diminished heart rate variability. Otherwise, no specific limitations on activity are necessary.
Medication
Corticosteroids
Careful replacement of glucocorticoids in patients with known adrenal insufficiency is critical to avoid adrenal crisis and to allow for normal growth in children. Growth must be monitored closely, as overtreatment with glucocorticoids impairs linear growth.
Providing stress doses of hydrocortisone during illness or injury is another important feature of medical management. Typically, a doubling or tripling of the oral dose is sufficient for routine illnesses. A larger increase in dose (provided IV if necessary) is required for severe illness and major trauma (see Adrenal Insufficiency).
Hydrocortisone (Hydrocortone, Cortef)
Has mineralocorticoid and glucocorticoid effects. Useful in management of inflammation caused by immune response.
Adult
10-15 mg PO on awakening and 5-10 mg PO in early afternoon; a third dose may be required in some patients, especially during stress
Pediatric
Maintenance: 10-15 mg/m2/d PO divided tid; morning dose may be increased relative to evening doses to more closely mimic the endogenous circadian rhythm of glucocorticoid secretion
Mild illness: Double PO maintenance dose for routine illness, triple the PO maintenance dose in high fever or more severe illness
Severe illness, surgery, or trauma: Up to 10-fold increase above PO dose, given IV, or approximately 100 mg/m2/d
Corticosteroid clearance may decrease with estrogens; may increase digitalis toxicity secondary to hypokalemia
Documented hypersensitivity; viral, fungal, or tubercular skin infections
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Avoid overtreatment, which leads to iatrogenic Cushing syndrome and poor linear growth; administer with meals to decrease GI upset; early-onset adverse effects include glucose intolerance, hypertension, agitation, and indigestion (less likely at physiologic doses); late-onset adverse effects include immune suppression and increased susceptibility to sepsis, adrenal suppression, hypertension, urinary calcium loss and osteopenia, gastric irritation, and bleeding (less likely at physiologic doses)
Prednisone (Deltasone)
Immunosuppressant for treatment of autoimmune disorders; may decrease inflammation by reversing increased capillary permeability and suppressing PMN activity.
Stabilizes lysosomal membranes and suppresses lymphocytes and antibody production.
In patients who have difficulty complying, it is acceptable to replace hydrocortisone with an equipotent dose of prednisone (prednisone is 4-5 times as potent as hydrocortisone).
Doses can be adjusted based on symptoms and monitoring linear growth and weight gain.
Adult
2.5-7.5 mg/d PO; titrate up or down depending on clinical response
Pediatric
4-5 mg/m2/d PO; titrate up or down depending on clinical response
Coadministration with estrogens may decrease prednisone clearance; concurrent use with digoxin, may cause digitalis toxicity secondary to hypokalemia; phenobarbital, phenytoin, and rifampin may increase metabolism of glucocorticoids (consider increasing maintenance dose); monitor for hypokalemia with coadministration of diuretics
Documented hypersensitivity; viral infection, peptic ulcer disease, hepatic dysfunction, connective tissue infections, and fungal or tubercular skin infections; GI disease
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Administer with meals to decrease GI upset
Early-onset adverse effects include glucose intolerance, hypertension, agitation, and indigestion (less likely at physiologic doses)
Late-onset adverse effects include immune suppression and increased susceptibility to sepsis, adrenal suppression, hypertension, urinary calcium loss and osteopenia, gastric irritation, and bleeding (less likely at physiologic doses)
Fludrocortisone (Florinef)
Provides physiologic replacement of mineralocorticoid deficiency.
Dose must be sufficient to lower plasma renin activity to normal without inducing hypertension.
Adult
0.05-0.2 mg/d PO
Pediatric
0.05-0.1 mg/d PO; higher doses may be necessary in adolescents
Antagonizes effects of anticholinergics; rifampin, hydantoins, and barbiturates decrease effects of fludrocortisone; decreases salicylate levels
Documented hypersensitivity; systemic fungal infections
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Excessive dosing can lead to hypertension;
monitor for dizziness, severe or continuing headaches, swelling of feet or lower legs, or unusual weight gain; administer with food to minimize adverse GI effects
Dexamethasone (Decadron)
For various allergic and inflammatory diseases. Decreases inflammation by suppressing migration of PMN leukocytes and reducing capillary permeability.
Adult
0.5 mg/d PO; titrate up or down depending on clinical response
Pediatric
0.03-0.15 mg/kg/d PO/IV/IM; titrate up or down depending on clinical response
Effects decrease with coadministration of barbiturates, phenytoin and rifampin; dexamethasone decreases effect of salicylates and vaccines used for immunization
Documented hypersensitivity; active bacterial or fungal infection
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Increases risk of multiple complications, including severe infections; monitor adrenal insufficiency when tapering drug; abrupt discontinuation of glucocorticoids may cause adrenal crisis; hyperglycemia, edema, osteonecrosis, myopathy, peptic ulcer disease, hypokalemia, osteoporosis, euphoria, psychosis, myasthenia gravis, growth suppression, and infections are possible complications of glucocorticoid use
