What are the key characteristics of guttate psoriasis. How does it differ from other types of psoriasis. What triggers guttate psoriasis outbreaks. How is guttate psoriasis diagnosed and treated. Can guttate psoriasis be prevented or managed long-term.

Understanding Guttate Psoriasis: A Unique Form of Autoimmune Skin Condition

Guttate psoriasis is a distinct variant of psoriasis characterized by small, teardrop-shaped, red, and scaly spots on the skin. This form of psoriasis typically affects children and young adults, making up less than 30% of all psoriasis cases. Unlike plaque psoriasis, guttate psoriasis rarely leaves scars and presents with thinner lesions.

As an autoimmune condition, guttate psoriasis occurs when the body’s immune system mistakenly attacks its own cells. This can result in a single outbreak or multiple flare-ups over time. In some instances, the condition may persist, requiring ongoing management and treatment.

Key Features of Guttate Psoriasis

• Small, teardrop-shaped lesions
• Red and scaly appearance
• Primarily affects arms, legs, and upper body
• Can spread to face, ears, and scalp
• Rarely affects palms, soles, or nails

Recognizing the Symptoms and Stages of Guttate Psoriasis

Identifying guttate psoriasis early can lead to more effective treatment and management. The condition often manifests differently from other forms of psoriasis, with distinct symptoms and stages of progression.

Common Symptoms

The primary symptom of guttate psoriasis is the appearance of small, red, scaly spots on the skin. These lesions are typically less thick than those seen in plaque psoriasis and can cover various parts of the body.

Areas Commonly Affected

• Arms
• Legs
• Upper body
• Face (less common)
• Ears (less common)
• Scalp (less common)

Seasonal variations can impact the severity of guttate psoriasis. Many individuals experience more frequent flare-ups during winter months when the air is drier, while symptoms may improve during summer.

Stages of Guttate Psoriasis

Guttate psoriasis is typically categorized into three stages based on the extent of skin coverage and impact on daily life:

1. Mild: Spots cover approximately 3% of the skin surface
2. Moderate: Lesions affect about 3-10% of the skin
3. Severe: 10% or more of the body is covered, potentially affecting the entire skin surface

It’s important to note that the stage classification can also depend on how the condition interferes with daily activities and quality of life. For instance, psoriasis on visible areas like the face or scalp might be considered severe even if it covers a small percentage of the body, due to its impact on appearance and social interactions.

Unraveling the Causes and Triggers of Guttate Psoriasis

Understanding the factors that contribute to guttate psoriasis outbreaks is crucial for effective management and prevention. While the exact cause remains unclear, several triggers have been identified.

Primary Trigger: Bacterial Infections

The most common trigger for guttate psoriasis is a bacterial infection, particularly streptococcus (strep throat). This infection can stimulate an immune system reaction that leads to the characteristic skin lesions.

Genetic Predisposition

In some cases, guttate psoriasis has a genetic component. Individuals with a family history of the condition may be at a higher risk of developing it themselves.

Other Potential Triggers

• Upper respiratory infections
• Sinus infections
• Influenza
• Tonsillitis
• Stress
• Skin injuries (cuts, burns, or bites)
• Certain medications (e.g., antimalarials and beta-blockers)

Identifying and managing these triggers can play a significant role in preventing or minimizing guttate psoriasis outbreaks.

Diagnosing Guttate Psoriasis: From Physical Examination to Advanced Testing

Accurate diagnosis of guttate psoriasis is essential for appropriate treatment and management. Healthcare providers employ various methods to confirm the condition and rule out other skin disorders.

Initial Assessment

The diagnostic process typically begins with a thorough medical history review and physical examination. Doctors will inquire about recent illnesses, medications, and family history of psoriasis or other autoimmune conditions.

Physical Examination

A careful inspection of the skin is usually sufficient for an experienced dermatologist to diagnose guttate psoriasis. The characteristic appearance of small, teardrop-shaped lesions is often a clear indicator.

Additional Diagnostic Tests

In some cases, further tests may be necessary to confirm the diagnosis or rule out other conditions:

• Blood tests: To check for signs of infection or inflammation
• Throat culture: To detect the presence of streptococcus bacteria
• Skin biopsy: A small sample of skin is examined under a microscope to confirm the diagnosis and rule out other skin conditions

These diagnostic tools help healthcare providers develop an accurate treatment plan tailored to each individual’s needs.

Effective Treatment Strategies for Guttate Psoriasis

While guttate psoriasis outbreaks typically last 2 to 3 weeks, treatment can help manage symptoms, prevent complications, and reduce the likelihood of future flare-ups. Treatment approaches vary based on the severity of the condition and individual patient factors.

Topical Treatments

Over-the-counter and prescription topical medications are often the first line of treatment for mild to moderate cases:

• Cortisone creams: Reduce itching and inflammation
• Dandruff shampoos: Manage scalp symptoms
• Coal tar lotions: Soothe irritated skin
• Moisturizers: Hydrate and protect the skin
• Prescription vitamin A derivatives: Promote skin cell turnover

Systemic Medications

For more severe cases, oral or injectable medications may be prescribed:

• Corticosteroids: Reduce inflammation throughout the body
• Biologics (e.g., guselkumab, ixekizumab): Target specific components of the immune system
• Apremilast (Otezla): Inhibits an enzyme involved in inflammation
• Deucravacitinib (Sotyktu): A newer medication that modulates immune response
• Methotrexate: Suppresses the immune system and reduces skin cell turnover

Phototherapy

Light therapy, or phototherapy, can be an effective treatment option for guttate psoriasis:

• Controlled exposure to ultraviolet (UV) light
• May be combined with photosensitizing medications
• Natural sunlight exposure can also be beneficial for some patients

Long-Term Management and Prevention of Guttate Psoriasis

While guttate psoriasis cannot always be prevented, there are strategies to reduce the frequency and severity of outbreaks.

Lifestyle Modifications

• Stress management: Practice relaxation techniques and maintain a balanced lifestyle
• Skin care: Keep skin moisturized and avoid harsh soaps or irritants
• Diet: Some individuals may benefit from identifying and avoiding trigger foods
• Exercise: Regular physical activity can help manage stress and improve overall health

Infection Prevention

Since bacterial infections, particularly strep throat, are common triggers for guttate psoriasis, taking steps to prevent these infections is crucial:

• Practice good hygiene, including regular handwashing
• Avoid close contact with individuals who have active infections
• Seek prompt treatment for any suspected infections

Regular Medical Check-ups

Maintaining regular appointments with a dermatologist or healthcare provider can help monitor the condition and adjust treatment as needed. This proactive approach allows for early intervention and better long-term management of guttate psoriasis.

Emerging Research and Future Treatments for Guttate Psoriasis

The field of dermatology continues to evolve, with ongoing research into new treatments and management strategies for guttate psoriasis. These advancements offer hope for improved outcomes and quality of life for individuals living with this condition.

Targeted Therapies

Researchers are exploring more targeted therapies that can address the specific immune system dysfunctions associated with guttate psoriasis. These may include:

• New biologic medications that target specific inflammatory pathways
• Gene therapy approaches to correct underlying genetic factors
• Personalized medicine strategies based on individual genetic profiles

Microbiome Research

Growing evidence suggests that the skin microbiome may play a role in psoriasis development and progression. Studies are investigating:

• Probiotics and prebiotics to promote a healthy skin microbiome
• Topical treatments that target specific bacterial populations
• The relationship between gut health and skin inflammation

Combination Therapies

Researchers are exploring innovative combinations of existing treatments to enhance efficacy and reduce side effects. These may include:

• Combining phototherapy with targeted medications
• Sequential or rotational use of different treatment modalities
• Integrating conventional treatments with complementary therapies

As research progresses, individuals with guttate psoriasis can look forward to more effective, personalized treatment options that address both the symptoms and underlying causes of this challenging skin condition.

Guttate psoriasis is a type of psoriasis that shows up on your skin as red, scaly, small, teardrop-shaped spots. It doesn’t normally leave a scar. You usually get it as a child or young adult. Less than a third of people with psoriasis have this type. It’s not as common as plaque psoriasis.

It’s an autoimmune disease, meaning your body treats your own cells like invaders and attacks them. You might get it only once, or you could have several flare-ups. In some cases, this type of psoriasis doesn’t go away. With the help of your doctor, you can find a treatment to keep your symptoms under control.

The spots you get from guttate psoriasis aren’t as thick as the ones from plaque psoriasis. You can sometimes have both kinds of psoriasis at once. You probably would get them on your arms, legs, and upper body.

It can sometimes spread from there to your face, ears, and scalp. But it doesn’t show up on your palms, the soles of your feet, or nails like other forms of psoriasis can. You’re more likely to have a flare-up during the winter, when the air is dry. Your symptoms may clear up more quickly in summer.

There are three:

• Mild. Only a few spots cover about 3% of your skin.
• Moderate. Lesions cover about 3%-10% of your skin.
• Severe. Lesions cover 10% or more of your body and could cover your entire body.

The stage can also be based on how much they interfere with your daily life and activities. For example, psoriasis on your face or scalp can affect only 2%-3% of your total body surface area, but it could be classified as severe because it affects your appearance and livelihood. Psoriasis on your hands might only cover 2% total body surface area, but could affect your livelihood if you work with your hands. In that case it would be classified as moderate to severe.

An outbreak is usually triggered by a bacterial infection — typically streptococcus (strep throat). It sets off an immune system reaction that causes the spots on your skin.

In some cases, guttate psoriasis is genetic. If someone in your family has it, your chances of getting it go up.

Other triggers include:

• Upper respiratory infections
• Sinus infections
• Flu
• Tonsillitis
• Stress
• Cuts, burns, or bites on your skin
• Some drugs you take (antimalarials and beta-blockers)

Your doctor will want to know your medical history, especially what kinds of medications you may be taking. They’ll look at your skin. Usually, a physical exam gives your doctor enough information to diagnose or rule out guttate psoriasis.

If they need more information, your doctor may take a blood sample or a throat culture to check for strep. It’s also common for doctors to perform a skin biopsy when they want to know for sure what you have.

In most cases, an outbreak of guttate psoriasis lasts 2 to 3 weeks. But your doctor may want to treat your symptoms and help prevent other infections in your body.

• Medications. There are several over-the-counter or prescription options for the itchy, flaky skin, as well as the dryness and swelling. They include:
  • Cortisone cream for itching and swelling
  • Dandruff shampoo for your scalp
  • Lotions with coal tar to soothe your skin
  • Moisturizers
  • Prescription medicines with vitamin A
  • If your case is more serious, your doctor may give you a prescription to take by mouth. These include:
    • Corticosteroids
    • Biologics (guselkumab, ixekizumab)
    • Apremilast (Otezla)
    • Deucravacitib (Sotyktu)
    • Methotrexate
• Phototherapy. Also known as light therapy, this is another option. Your doctor will shine ultraviolet light onto your skin during this treatment. They may also give you medication to make your skin react more quickly to light. Sometimes, just going out into the sunshine can help.

What is guttate psoriasis?

IMPORTANT
The information in this section should not be used for self-diagnosis or self-treatment. In case of pain or other exacerbation of the disease, only the attending physician should prescribe diagnostic tests. For diagnosis and proper treatment, you should contact your doctor.

Guttate psoriasis is a type of psoriasis, the distinguishing features of which are the absence of damage to the nail plates and the spontaneous, unpredictable spread of skin rashes associated with the presence of an infection in the body. The primary element is a pink teardrop-shaped papule. The appearance of a papule is accompanied by itching. Initially, the rash is localized on the trunk and extremities, but subsequently spreads over the entire skin, with the exception of the palms and soles. The disease is diagnosed clinically when the psoriatic triad is detected, using histological data. The most effective methods of treatment are PUVA therapy and plasmapheresis.

General

Guttate psoriasis is a rather rare form of scaly lichen of autoimmune coloration with a chronic course. Dermatosis has no gender or racial differences, does not have a clear seasonality, and is not endemic. Most often, guttate psoriasis is diagnosed in school-age children, young men and women. In the world, more than 4% of the population suffer from psoriasis, teardrop-shaped accounts for about 2 million people. Guttate psoriasis is organ-specific, often combined with somatic pathology, acute or exacerbated chronic infections. It is assumed that such combinations are due to a violation of the protective properties of the skin and easy penetration into the body of infectious agents, which are one of the main triggers in the trigger mechanism for the development of the disease.

It is believed that disseminated guttate psoriasis shortens the life of a woman by 3 years, men – by 1.5 years. The reason for the shortening of life is autoimmune disorders. The development of guttate psoriasis is adversely affected by bad habits, especially smoking and a high atherogenic dietary profile. Smoking a pack of cigarettes a day increases the risk of guttate psoriasis by 2 times. Eating a large amount of fish (a natural source of polyunsaturated fatty acids) reduces the likelihood of the disease by 3 times. The urgency of the problem is associated with the severe course of the psoriatic process, which significantly worsens the quality of life of patients.

Guttate psoriasis

Causes of guttate psoriasis

The vast majority of dermatologists consider the main cause of the development of guttate psoriasis to be an infection of any etiology: influenza, tonsillitis, pneumonia, acute respiratory diseases of the upper respiratory tract, mucosal candidiasis. In favor of the infectious theory, the presence of pathogenic pathogens in a scraping from a teardrop-shaped plaque testifies. An infectious disease either leads to the debut of the pathology, or exacerbates the course of other forms of psoriasis and stimulates their transformation into guttate psoriasis. The background of pathological changes is stress, overwork, decreased immunity, hereditary predisposition, or a combination of several of these factors. Despite the fact that a pathogenic pathogen is determined in scrapings from plaques, guttate psoriasis is not an infectious disease, it is not contagious.

In the pathogenesis of guttate psoriasis, the leading role belongs to autoimmune reactions. The presence of infection activates the genes responsible for the development of the disease, stress affects neuropeptides that can stimulate keratinocytes, which, in turn, release cytokines. Cytokines activate lymphocytes of the immune system and histiocytes of the connective tissue component of the skin, which attract eosinophils. There are three stages in the development of guttate psoriasis: sensitization, latent existence and effector. In the first phase, the mechanism of the antigen-antibody reaction is launched, where pathogenic microorganisms that penetrate the skin act as antigens, and cells of the immune and reticuloendothelial system act as antibodies. In the second phase, there is a latent accumulation of antibodies produced by dermal cells and lymphocytes of the immune system. Antibodies, due to an overabundance, bind not only foreign particles, but also endogenous skin structures.

Finally, in the third phase, a manifest rash of primary elements begins on the surface of the skin. The time of the onset of the final phase cannot be predicted, since the duration of the latent period depends on the virulence of the pathogen or the cytotoxicity of another pathogen, its quantity and the resistance of the organism. It should be noted that in the case of guttate psoriasis, genetic predisposition does not play a decisive role, since there are many genes responsible for the development of guttate psoriasis, and the genetic transmission of any form of psoriasis does not obey Mendel’s laws. It is impossible to consider guttate psoriasis as genodermatosis, one can only speak of a genetically determined heterogeneous disease.

Guttate psoriasis classification

In dermatology, it is customary to classify guttate psoriasis according to severity, taking into account the prevalence of skin lesions. Distinguish:

Severe guttate psoriasis is a common rash that covers more than 10% of the skin. They are localized everywhere, seriously disrupt the patient’s condition, require medical intervention in a specialized hospital and treatment according to an individual program until the primary psoriatic elements completely regress.

Symptoms of guttate psoriasis

The disease has an undulating course, remissions are replaced by relapses, especially frequent in the autumn-winter period. Clinical manifestations of guttate psoriasis occur spontaneously. The primary element is a bright red teardrop-shaped papule, 3 to 10 mm in diameter, covered with a silvery scale. Papules grow along the periphery, merge and turn into plaques. When injured, the elements are prone to ulceration and transformation into exudative psoriasis. The rash is accompanied by itching. The rash is located on the trunk and limbs – this is a typical localization of the primary elements of guttate psoriasis. The face almost always remains free, the nail plates are not affected. The rash may resolve on its own or transform into a more severe form of psoriasis. The disappearance of the rash is not a guarantee of recovery.

Diagnosis of guttate psoriasis

When making a diagnosis of guttate psoriasis, data on a recent infection, complaints, and the presence of a specific diagnostic triad: stearin stain, terminal film, and dewdrop bleeding are taken into account. In the KLA, an increased ESR and leukocytosis are determined, according to biochemistry, the presence of a rheumatoid factor is detected. Children who have had a streptococcal infection are given serological tests with the detection of an increased titer of antistreptolysin-O and antideoxyribonuclease, a swab is taken from the nasopharynx with bacteriological examination for hemolytic streptococcus.

Histology is typical for drip psoriasis, morphological changes indicate the immaturity of the epidermal cells, the presence of T-lymphocytes in the biopsy, and the phenomena of hyperkeratosis. The disease is differentiated with other varieties of psoriasis, pink lichen, secondary syphilis, drug toxicoderma, dermatitis and viral exanthema.

Treatment of guttate psoriasis

Dermatosis is resistant to ongoing therapy, requires patience from both the patient and the dermatologist. The treatment is complex, depending on the severity of the process, it is carried out on an outpatient or inpatient basis. First of all, sanation of foci of chronic infection is carried out, residual effects of acute forms of acute respiratory infections and acute respiratory viral infections are treated, and concomitant somatic pathology is corrected. The dermatologist selects an individual program of anti-atherogenic nutrition profile with the use of polyunsaturated fatty acids. Simultaneously carry out symptomatic therapy. For guttate psoriasis, PUVA therapy is most effective when given in small doses under medical supervision. The use of plasmapheresis can reduce the frequency of relapses.

Medications for guttate psoriasis are used for different purposes and according to different therapeutic regimens. For example, hormonal ointments, taking into account the area of ​​\u200b\u200bdamage to the skin, are used only in short courses; Antibacterial therapy against the inoculated hemolytic streptococcus is carried out by prescribing long cycles of antibiotic therapy using cephalosporins. The longest time is the intake of immunomodulators.

Vitamin therapy (A, D, C, E, group B) and preparations containing monoclonal antibodies are shown. If the growths of the primary elements are significant and continue to progress, retinoids are used internally and ointments with calcitriol externally. Assign sedative, antipruritic and antihistamine therapy. Baths with bran give a good effect. The prognosis is relatively favorable, taking into account the undulating course of guttate psoriasis and a decrease in the quality of life of patients.

You can share your medical history, what helped you in the treatment of guttate psoriasis.

   Treatment of acute guttate psoriasis in addition to drugs directed against streptococcal infection

   Survey question

   The purpose of this review is to find out how well different non-streptococcal agents (i.e. drugs that do not target streptococcal infection) work for acute guttate psoriasis or guttate flare-ups of chronic psoriasis in adults and children, and how safe they are compared with placebo (identical but inactive agent) or other treatment. This topic is important because there is a lack of information and evidence regarding the best way to treat guttate psoriasis. We collected and analyzed all relevant studies to answer this question and found one study.

   Relevance

   Psoriasis is a chronic skin disease characterized by red, scaly patches (known as plaques). About 2% of people suffer from psoriasis. Guttate psoriasis is characterized by smaller lesions and is more common in children and young adults. Treatment for guttate psoriasis aims to clear the skin of lesions for as long as possible and includes topical (applied to the skin) or oral (taken by mouth) drugs, phototherapy (i.e., ultraviolet light therapy), and biologics (through which a living the body produces the active substance). It is not known which of these options is better at eliminating lesions in guttate psoriasis, and whether they are safe.

   Study profile

   We found one relevant study comparing the effects of intravenous injections of two different lipid (fat) emulsions twice a day for 10 days: one emulsion (two or more liquids that often do not mix) was derived from fish oil, and the other is from soybean oil. The follow-up period for participants was 40 days. The study was conducted in Germany among 21 adults (18 men and 3 women) aged 21 to 65 years. The average area of ​​skin lesions was 25%. Participants were hospitalized for acute guttate psoriasis. The study was funded by an oil emulsion company.

   Main results

   Treatment options for which we did not find evidence include phototherapy and topical, oral, and biologic agents. The only study found did not assess two main outcomes: the percentage of treated people whose skin cleared (or nearly cleared) of lesions, and side effects or harm from treatment.

   Most secondary outcomes were also not assessed, including worsening of guttate psoriasis or recurrence within six months of completing treatment, and the percentage of participants who achieved a Psoriasis Area and Severity Index of 75 or a Physician’s Overall Score of 1 or 2. The included study did not report about the assessment of harm from treatment; however, the study authors reported rare skin irritation at the injection site, but did not state the number of participants who experienced it.

   Study participants self-assessed several outcomes, including skin lesions, impact on daily life, itching, burning and pain. After 10 days of treatment, study participants who received the fish oil lipid emulsion (75% of people in this group) experienced greater improvement than those who received the soy oil lipid emulsion (18% of people in this group). However, these results are mixed because they are based on very low quality evidence.

   Evidence is current to June 2018.

   Quality of evidence

   We rated the quality of the available evidence as very low.

   We considered that the study may be at risk of bias due to design limitations and the participation of only a small number of people. In addition, only adults were included in the study, although guttate psoriasis is more common in children.
