Understanding Psoriasis in Infants: What Parents Should Know

Created by Doctor LeO in Skin Health, 1 months ago

The presence of congenital psoriasis in infants, if left undetected and untreated, can cause significant discomfort and pain. Parents often mistake psoriasis in infants for other skin conditions like eczema or heat rash. In this article, we aim to shed light on the crucial aspects of psoriasis in infants.

1. What is Psoriasis in Infants?

Psoriasis is a chronic inflammatory skin condition characterized by an accelerated production of new skin cells, resulting in the abnormal accumulation of dead skin cells. This buildup leads to the formation of red patches with white or silvery scales, often accompanied by itching.
While psoriasis can affect individuals of all ages, it most commonly develops between the ages of 15 and 30. Although relatively rare, psoriasis can also manifest in infants. Importantly, psoriasis is not contagious, so parents should not assume that their child contracted the condition from other babies or adults.

2. Causes of Psoriasis in Infants

The precise cause of psoriasis remains unknown. It is believed to be a complex interplay of genetics, susceptibility to autoimmune diseases, and environmental factors. Family medical history plays a significant role in the development of psoriasis in infants, with around 10% of children at risk if one parent has the condition and 40% at risk if both parents are affected.

Furthermore, a family history of autoimmune disorders like thyroid disease, multiple sclerosis, or Crohn's disease increases the likelihood of congenital psoriasis in infants since psoriasis itself is considered an autoimmune disorder. In older babies and adults, obesity is also a risk factor for psoriasis. Additionally, factors such as medication usage, cold weather, and skin injuries can trigger the condition in infants. For infants and young children, psoriasis often emerges following infections, often after a cold.

3. Types of Psoriasis in Infants

  • Diaper Psoriasis: This is a common type of psoriasis in infants, appearing in the diaper area. However, it can be challenging to diagnose due to the various types of rashes infants typically experience in this area.
  • Plaque Psoriasis: Plaque psoriasis, the most prevalent form, exhibits red, white, or silver-scaled plaques. In children, these plaques are typically smaller and softer.
  • Guttate Psoriasis: More common in infants and children than in adults, guttate psoriasis often begins after strep throat or a cold, manifesting as small, dot-like patches across the body.
  • Pustular Psoriasis: Characterized by red patches with pus in the center, this form is uncommon in newborns.
  • Scalp Psoriasis: Scalp psoriasis primarily affects the scalp, leading to red skin and flaky white patches.
  • Inverse Psoriasis: While rare in infants, this form appears as red patches in skin folds, such as under the arms and behind the knees, and can co-occur with psoriasis on other body parts.
  • Generalized Psoriasis: This rare form, if left untreated, can be life-threatening. It results in intense itching and painful skin shedding.
  • Nail Psoriasis: Although not common in infants, nail psoriasis can cause pitting, ridges, discoloration, or nail shedding, often in conjunction with skin lesions.

4. Diagnosis of Psoriasis in Infants

Diagnosing psoriasis in infants can be challenging since it closely resembles other common skin conditions. Parents must be aware of their family's medical history and carefully observe their child to assist healthcare providers in the diagnosis process. If a baby's rash persists despite using specialized creams and home remedies, it is crucial to consult a doctor for a thorough assessment. Diagnosing psoriasis in infants often requires careful and prolonged observation.

Most forms of psoriasis present as red patches with white scales on various body parts, potentially causing itching, pain, bleeding, or cracking. Common locations for psoriasis in infants include the face, neck, elbows, knees, diaper area, and scalp. Physicians rely on the appearance of skin lesions and family medical history to diagnose psoriasis in infants. Fortunately, psoriasis in infants can be treated effectively, and it does not typically recur as it does in adults.

5. Distinguishing Psoriasis in Infants from Eczema

Eczema is a prevalent skin condition in babies, characterized by dry and red patches, often found behind the knees, on the arms, and the face. Eczema rashes tend to be itchy and may crack or bleed. Unlike psoriasis, eczema does not exhibit white scales on red patches of skin and typically responds well to over-the-counter creams and moisturizers. Moreover, eczema rarely affects a baby's diaper area.

It is possible for children to have both eczema and psoriasis simultaneously. If your baby has an unexplained rash, consulting a doctor is advisable to determine the cause and develop an appropriate treatment plan to restore your baby's skin to health.

6. Treatment Approaches for Psoriasis in Infants

Moisturizers and emollients are essential for maintaining the softness and health of a baby's skin, which can support treatment with ointments. Various moisturizer types, including bath oils, creams, solutions, and ointments (such as coal tar, vitamin D, topical steroids, and dithranol), can be applied directly to the skin. For some children, moisturizers and emollients alone may be sufficient to manage psoriasis. Parents should also ensure that their child is not exposed to excessively hot or cold temperatures and should protect them from direct sunlight. Keeping affected areas clean and dry is essential. In most cases, oral medications are not recommended for infants with psoriasis.

In conclusion, psoriasis in infants is a rare but manageable dermatological condition. Parents play a crucial role in early detection and treatment. Consulting a healthcare professional is vital for an accurate diagnosis and the development of an appropriate treatment plan tailored to your child's needs. With proper care and medical guidance, psoriasis in infants can be effectively managed, allowing your baby to lead a healthy, happy life.
