Treatment

Medical Care

  • Ichthyosis and acanthosis nigricans can be treated with alpha hydroxy acids (eg, ammonium lactate, glycolic acid) and urea to improve cosmetic appearance.
  • Epileptic seizure treatment is the most difficult aspect of therapy.

Surgical Care

Surgical therapy of associated ophthalmologic problems may be indicated.

Consultations

  • Consultation with a neurologist is needed for seizure management.
  • Consultation with a developmental specialist is needed for mental retardation.
  • Consultation with an endocrinologist is needed for possible pituitary hypogonadism.
  • Consultation with an ophthalmologist is needed for possible retinitis pigmentosa, strabismus, ptosis, blepharospasm, cataract, and nystagmus.
  • Consultation with a genetic counselor may be obtained as appropriate.

Medication

The goals of pharmacotherapy are to reduce morbidity and to prevent complications.

Keratolytics

These agents promote shedding of hyperkeratotic skin. They are modifiers of keratinocyte adhesion, differentiation, and proliferation.


Ammonium lactate lotion (AmLactin, Lac-Hydrin)

Contains lactic acid, an alpha hydroxy acid with keratolytic action. Comes in 12% and 5% strengths. The 12% concentration may cause irritation on the face. Causes disadhesion of corneocytes.

Adult

Apply topically to lesion or liberally to all affected areas bid for xerosis or other dry skin conditions

Pediatric

Apply as in adults

Pregnancy

B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals

Precautions

May sting or cause pain if applied on broken skin; the 12% concentration may cause irritation with erythema, burning, and peeling if applied to the face


Glycolic acid

Alpha hydroxy acid with keratolytic action.

Adult

Apply to affected areas prn

Pediatric

Apply as in adults

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

May sting or cause pain if applied on broken skin; for external use only


Urea (Ureaphil, Ureacin-40, Aquacare)

Promotes hydration and removal of excess keratin in conditions of hyperkeratosis. Available in 10-40% concentrations.

Adult

Apply to affected areas prn

Pediatric

Apply as in adults

May decrease effects of lithium

Documented hypersensitivity; severely impaired renal function; active intracranial bleeding; marked dehydration; frank liver failure; infusion into lower extremity veins in elderly patients may cause phlebitis and thrombosis

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

Do not use if intracranial bleeding is present, unless prior to surgical intervention to control hemorrhage (reduction of brain edema by urea may result in reactivation of intracranial bleeding); may increase risk of venous thrombosis and hemoglobinuria in patients with hypothermia; caution in renal impairment
