Guttate psoriasis, also known as psoriasis vulgaris or type III, is a form of chronic inflammatory skin disease that belongs to the group of psoriatic dermatoses. The disease is characterized by the appearance of multiple small, teardrop-shaped, erythematous papules covered with silvery-white scales. Guttate psoriasis usually occurs suddenly, often in the context of a streptococcal infection such as strep throat, and may be associated with other forms of psoriasis. Unlike more common forms such as psoriasis vulgaris, guttate psoriasis is more common in young people and can affect large areas of the skin, making it difficult to treat.
History of the disease and interesting historical facts
Guttate psoriasis has been known to medicine for several centuries. The first mentions of skin diseases resembling psoriasis were made in ancient Egypt and Greece. However, the systematization and detailed study of the guttate variant occurred only in the 19th century. One of the first to describe this disease was the Swedish dermatologist Ricardus (Richard) Olsson, who distinguished it from other forms of psoriasis in 1860. Interestingly, this disease is most often observed in regions with a cold climate, which may indicate the influence of the external environment on its development. In recent decades, scientists have become increasingly interested in the genetic and immunological aspects of the disease, which opens up new horizons in understanding and treating this dermatosis.
Epidemiology
Epidemiological studies have shown that guttate psoriasis occurs in 2-8% of all psoriasis patients, varying depending on the region and ethnicity. The disease can occur at any age, but is most often diagnosed in people under 30 years of age. There is evidence that among patients with guttate psoriasis, about 70% are men. The existence of a genetic predisposition is also confirmed by statistics: the risk of developing this type of psoriasis in first-degree relatives increases by 3-4 times compared to the general population.
Genetic predisposition to this disease
There are many studies that highlight a genetic predisposition to guttate psoriasis. The main hypothesis is that certain alleles in genes play a major role in the development of this disease, especially in relation to the immune response. The main genes involved include:
- HDAC9 (histone acetyltransferase 9)
- TNF (tumor necrosis factor)
- IL-12 (interleukin 12)
- IL-23 (interleukin 23)
- HLA-Cw6 (human leukocyte antigen)
Mutations and polymorphisms in these genes are associated with the activity of inflammatory processes, which is confirmed by studies conducted on genetic models. However, how these factors interact with each other and the influence of the external environment on the development of the disease have not been fully studied.
Risk factors for the development of this disease
Risk factors that contribute to the development of guttate psoriasis are varied and range from physical to chemical. The main ones include:
- Streptococcal infections such as tonsillitis
- Stressful situations leading to an immune response
- Skin injuries (such as cuts or sunburn)
- Use of certain medications, including beta blockers and lithium
- Alcohol and smoking
An important aspect is that the listed factors can not only provoke the onset of the disease, but also contribute to its relapse in those already diagnosed.
Diagnosis of this disease
Diagnosis of guttate psoriasis begins with a thorough clinical examination and history taking. The main symptoms include:
- The appearance of teardrop-shaped papules with a diameter of 2-10 mm
- Erythema and swelling in the area of the rash
- Severe itching and discomfort
Laboratory tests may include a complete blood count, biochemistry panel, and serologic tests to confirm the presence of streptococcal infection. Radiation studies are usually not required, but in complex cases, a skin biopsy may be required to rule out other dermatoses.
Differential diagnosis is extremely important because guttate psoriasis symptoms can be similar to other skin conditions such as eczema, acne, or lichen. It is important to rule out these conditions to develop the correct treatment plan.
Treatment
Treatment of guttate psoriasis can be multifactorial and requires an individual approach. General recommendations include:
- Avoiding disease triggers (stress, infections)
- Systemic and local therapy
- Photo and laser therapy
Pharmacological treatment may include:
- Topical corticosteroids
- Immunomodulators such as methotrexate
- For high severity of psoriasis - biological drugs
Surgical treatment is used extremely rarely, only in cases of significant skin lesions requiring surgical correction. For patients with recurrent forms, physiotherapy and complex rehabilitation programs are also often recommended.
List of medications used to treat this disease
The main medications used to treat guttate psoriasis include:
- Budesonide
- Clobetasol
- Methotrexate
- Etretinate
- Ustekinumab (Stelara)
- Adalimumb (Humira)
In the presence of concomitant diseases, other treatment systems may be used.
Disease monitoring
Monitoring guttate psoriasis is important to increase the chances of successful treatment and minimize complications. Regular monitoring measures include:
- Regular dermatologist examinations according to the established schedule
- Monitoring of concomitant diseases
- Assessing the patient's overall health indicators
The prognosis depends on the removal of triggers, adequate therapy and self-monitoring of the patient. Complications may include secondary skin infections, as well as the development of stationary and exudative forms of psoriasis.
Age-related features of the disease
Guttate psoriasis can progress differently in different age groups:
- In children and adolescents, it occurs more often after streptococcal infections;
- In adults, it may have a more protracted course and recur more often;
- In elderly people, complex forms with concomitant skin diseases are possible.
These aspects need to be taken into account when planning treatment and monitoring.
Questions and Answers
- What is guttate psoriasis? Guttate psoriasis is a form of psoriasis that appears as multiple teardrop-shaped papules on the skin, most often occurring after infections.
- What are the main risk factors? Major risk factors include streptococcal infections, stress, and certain medications.
- How is the disease diagnosed? Diagnosis includes clinical examination, laboratory tests and, in rare cases, biopsy.
- How is guttate psoriasis treated? Treatment may include topical and systemic anti-inflammatory drugs, phototherapy and, in severe cases, biological agents.
- What are the prognostic features of the disease? The prognosis depends on the removal of triggers and adequate therapy, but relapses and complications may develop.
Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov believes that the key points in the fight against guttate psoriasis are:
- Seeking medical attention promptly at the first symptoms is an important step to minimize further complications.
- Maintain your immune system at optimal levels through a balanced diet and regular exercise.
- Avoid self-diagnosing and using unfounded treatment methods - this can make the situation worse.
- Pay attention to your psycho-emotional state - stress causes an exacerbation of the disease, so it is important to find time for relaxation and rest.
