Expert advises
Although it is most often associated with skin symptoms, modern medicine defines it as a systemic disease that can also affect the joints and affect the cardiovascular and metabolic systems. The condition is less common in children than in adults, and its incidence increases with age, typically peaking during adolescence. The etiology of psoriasis in children is complex and multifactorial, resulting from the interaction of genetic predisposition, immune system disorders, and environmental influences.
Genetic and immunological basis of psoriasis in children
Genetics plays a key role, especially in the case of early-onset psoriasis (so-called type I), which is most common in children. If both parents are sick, the risk of developing psoriasis in a child is from 50% to even 75%In the case of one affected parent, this probability is estimated at approximately 15–20%. The most important genetic factor associated with early onset of the disease is the presence of a histocompatibility antigen HLA-Cw6.
The immunological mechanism involves an erroneous immune system response, in which T lymphocytes and proinflammatory cytokines attack the skin's own cells. This leads to a rapid acceleration of the epidermal cell growth cycle, resulting in excessive growth and desquamation.
Environmental factors (triggers) of psoriasis in children
Genetic background alone is usually not enough to cause symptoms to appear. - is needed trigger factorIn children, the most common triggers for psoriasis are:
- Infections: In particular, respiratory infections caused by streptococci (e.g., strep throat), which often precede the sudden onset of guttate psoriasis in children, are a common trigger. Viral infections, such as chickenpox or influenza, are also triggers.
- Stress: Emotional stress is one of the most important factors exacerbating the course of psoriasis in children, affecting the activity of the immune system.
- Skin injuries (Koebner phenomenon): Even minor damage to the epidermis, such as scratches, burns or injections, may, after a few days, become the site of a new psoriatic lesion.
- Lifestyle: Overweight, obesity and an incorrectly composed diet are strongly correlated with a more severe course of the disease and constitute a significant risk factor for the exacerbation of psoriasis in children.

The clinical picture of psoriasis in children shows significant differences compared to adults, including both the appearance of lesions and their typical location. the beginnings of psoriasis in children it should be mentioned, to early symptoms in infants, the so-called psoriatic diaper dermatitis, which manifests as bright red, shiny and clearly demarcated lesions in the perineal area, usually devoid of characteristic scales. Often the first sign of the disease, which may precede other symptoms by many years, are changes in the scalpAnother typical onset of psoriasis in children is the form droplet-like (seedling), which manifests itself by the sudden appearance of numerous, small lumps with a diameter of less than 1 cm, located mainly on the trunk, often, as already mentioned, after a streptococcal throat infection.

The silvery scales, a hallmark of this disease in adults, may be much more delicate, softer, or even absent in younger patients. Furthermore, psoriasis symptoms in children are much more likely to include bothersome itching and burning sensations in the affected areas. A greater tendency for spontaneous remission (clearing) of the lesions is also observed in the pediatric population.

Nail psoriasis in children – what are the symptoms?
It's good to know that Nail psoriasis in children is not a separate disease, but only one of the forms of psoriasis in children, which may involve different areas of the body.

Expert advises
Nail psoriasis in children often causes onycholysis, which is the separation of the nail from its bed, as well as subungual hyperkeratosis, delamination, and pronounced nail plate thickening. These changes can involve the nail matrix and folds, leading to onychodystrophy, which is particularly important from a medical perspective, as nail involvement in children is considered a risk factor for the development of psoriatic arthritis. Although it occurs less frequently than in adults, psoriatic arthritis manifests itself with pain, swelling, and morning stiffness, and in many young patients, joint pain may precede skin lesions.

- Care and removal of scales: An essential element is emollientswhich moisturize the skin, soothe itching and help regenerate the protective barrier. In the initial phase, keratolytic agents (urea, lactic acid, salicylic acid) to remove excess scales and facilitate the penetration of anti-inflammatory drugs. However, it should be remembered that preparations with salicylic acid must not be used in children under 2 years of age due to the risk of toxic absorption.
- Cygnoline (Anthralin): Considered to be "gold standard" in the treatment of psoriasis in children due to its high systemic safety profile. Although very effective, its use can be bothersome due to its characteristic odor and the risk of permanent staining of clothing and irritation of healthy skin.
- Glucocorticosteroids (steroids): They act quickly and effectively as anti-inflammatory drugs, but in the treatment of psoriasis in children they should be used under the supervision of a doctor, short-term and for limited spaces.
- Vitamin D3 analogues and calcineurin inhibitors: They are a safer alternative to steroids for long-term use. Calcineurin inhibitors (tacrolimus, pimecrolimus) are particularly recommended for the treatment of psoriasis in children in sensitive areas such as the face, joint flexures or genitals.

- Systemic (general) medications: Used for moderate to severe forms of psoriasis in children. Classic medications include methotrexate, acitretin (especially in pustular psoriasis, requires monitoring of bone growth) and cyclosporine A (used for a short period of time to quickly control severe conditions).
- Biological drugs: This is a cutting-edge form of treatment for pediatric psoriasis, targeting specific proteins in the immune system. Drugs such as etanercept, adalimumab, and ustekinumab are approved for the treatment of the most severe cases of psoriasis in children who do not respond to other treatments.
Lifestyle and avoidance of exacerbating factors are important elements of psoriasis treatment in children.
Effective treatment of psoriasis in children also involves taking care of their overall health. eliminating infections (NP. caries teeth, tonsillitis), which are the most common trigger for relapses in children. It is also important diet rich in fresh vegetables and fruits and avoiding stress, which can provoke changes in a significant number of patients.
