Forms of congenital ichthyosis

- Deferred ichthyoses (the mutation is on non-sex chromosomes)
– the first symptoms of the disease begin to appear after 2-12 months.

Symptoms of congenital ichthyosis
What does ichthyosis in newborns look like?
At birth, a child with ichthyosis seems to be “packed” in dense

a few hours to a week) the film starts to go off, after which

With age, the severity of symptoms somewhat decreases
(exception – harlequin syndrome). The skin gets normal color,
but its tightness and excessive flaking remains. When laminar

with other forms. It is characterized by the following manifestations:
- Increased peeling of the skin over the entire surface of the body, except for the face,

manifested by a small number of symptoms: increased desquamation,
increased skin pattern of the palms and feet, the presence of cracks. Main
the method of treating this form is to eliminate the cause of the disease (destroy

prescribe the following groups of drugs:
- Hormones-glucocorticosteroids (GCS) – it’s not completely clear why
hormones have a positive effect on the course of ichthyosis. but
in clinical studies, their effect has been fully proven.
For treatment, most often, use prednisone, hydrocortisone.
The average duration of the course is 4-7 weeks, after which
the dose begins to be gradually reduced;
- Vitamin A – this drug improves the metabolism in the skin and
stimulates the formation of intercellular substance. Dose and form
doctors choose medications individually, but most often use
short courses (up to 2 weeks). Vitamin A preparations are available in
active form, called Retinol / Retinol acetate. With allergies
