The Different Kinds of Psoriasis
Psoriasis, which is considered to be an autoimmune disease, is a chronic skin disorder. What this means is that instead of protecting your body, your immune system attacks the body. In the United States, over 6.7 million people are affected by psoriasis.
What does it look like to have psoriasis?
This condition causes your skin to develop painful, itchy patches of skin that appear to be scaly, and even red or silvery. These patches sometimes disappear and reappear over time, whether it be a couple days or a month.
While this is a general definition, there are multiple kinds of psoriasis. It is even possible for one person to live with different kinds of psoriasis at the same time. Take a deeper look and read on to understand the difference between each type of psoriasis and how to treat it.
Psoriasis symptoms and how to spot them.
Common psoriasis symptoms are:
- Itchy skin
- Joint pain, swelling, or stiffness
- Red skin patches
- Scaly, or even silver, patches of skin
Other symptoms of psoriasis are low self-esteem, anxiety, and mental stress. Also, depression is very common for people living with psoriasis. Symptoms, however, vary based of the kind of psoriasis someone is diagnosed with. Officially, these are the five kinds of psoriasis:
- Psoriatic Arthritis
It is also notable to mention that there are subcategories for the different types of psoriasis. These subcategories present differently, though, based on its location. Regardless of the type of psoriasis, it is never contagious.
Plaque psoriasis, also known as psoriasis vulgaris, is the most commonly diagnosed form of psoriasis. Approximately 85% of people who have psoriasis are diagnosed with plaque psoriasis. It is categorized by red, thick skin patches, typically layered with white or silvery, scaly skin. These patches appear most commonly on the:
- Lower back
The size of these patches are anywhere from 1-10 cm in width, though they can sometimes be bigger and cover larger parts of the body. When the patches become irritated by scratching symptoms will worsen.
How to Treat:
First, a doctor will most likely suggest using moisturizers to prevent the skin from becoming dry and irritated. Types of moisturizers to use are over-the-counter cortisone creams or moisturizers with an ointment base. You and your doctor can even work to find triggers that spike your psoriasis, such as sleep loss or stress.
Other treatment options include:
- Medications, such as tazarotene (Avage, Tazorac)
- Topical retinoids that reduce inflammation
- Vitamin D creams like calcitriol (Rocaltrol) and calcipotriene (Dovonex) that help to reduce the rate of skin cell growth.
- Coal tar applications, either by shampoo, cream, or oil.
Some cases of plaque psoriasis may even require light therapy. This type of treatment requires skin to be exposed to UVA and UVB rays. Some treatment options can include combining light therapy, oral medications, and ointments prescribed to help reduce the inflammation.
2. Pustular psoriasis
Pustular psoriasis, a fast forming type of psoriasis is extremely severe, defined by the vast, white pustules ringed with red skin.
Pustular psoriasis can sometimes infect more isolated parts, such as hands or feet. Adversely, it could also affect larger skin portions and cover most surfaces. Pustules also are known to combine with one another, this is where scaling can occur.
Some may experience remissive and recurring periods of pustule occurrences. While pus from this form of psoriasis is not infectious, flu-like symptoms can arise, such as:
- Muscle weakness
- Loss of appetite
- Rapid pulse
There are also three subcategories of pustular psoriasis
- Palmoplantar Pustulosis (PPP)
- Von Zumbusch
These types of pustular psoriasis come with their own, different sets of symptoms and varying severity.
How to Treat:
The size of areas affected by pustular psoriasis affect the kind of treatments required. Patches that are smaller can be treated by over-the-counter or prescription corticosteroid creams, while large areas affected may need light therapy or oral medication. Establishing any underlying causes for pustular psoriasis can also be a major factor into reducing any recurrences.
3. Psoriatic Arthritis
A serious condition, Psoriatic Arthritis, is arduous and limiting to the body, and affects over one-third of people living with psoriasis. Five different types of psoriatic arthritis exist, each containing their own set of symptoms. Unfortunately, there is not a cure for this kind of psoriasis.
Psoriasis is an autoimmune disease which triggers the body, making it attack the skin and joints. This kind of psoriasis typically affects the hands very seriously and inflicts multiple joints. Commonly, symptoms appear on the skin before they do on the joints.
How to Treat:
Possible treatments for living with psoriatic arthritis are taking nonsteroidal anti-inflammatory drugs, typically referred to NSAIDs. Common NSAID options are ibuprofen, or Advil, and naproxen sodium. This type of medication can help to reduce swelling and pain often affiliated with psoriatic arthritis.
Other options that help reduce the inflammation one may experience are by being prescribed medication, including prednisone which is an oral corticosteroid. Topical medications to also be prescribed are salicylic acid, tazarotene, or calciopotriene. Another option may even be light therapy to reduce the symptoms of psoriatic arthritis.
Lastly, an uncommon group of medication is left to be discussed. These include disease-modifying antirheumatic drugs, known as DMARDs, which are also used to ease joint damage and inflammation. There is a subcategory of DMARDs, referred to as biologics, that are also prescribed to work on a cellular level.
4. Guttate Psoriasis
Guttate psoriasis presents as tiny, red spots on skin, and is the second most common type of psoriasis that affects approximately ten percent of people living with this condition. Typically, this type of psoriasis begins either in childhood or as a young adult.
The markings associated with guttate psoriasis are separated, small drop-like shapes. These spots typically show up on limbs and torso, but they may also affect the face and scalp. Generally, these spots aren’t as thick as those with plaque psoriasis, though over time they may develop and turn into plaque psoriasis.
Guttate psoriasis occurs after specific triggers, such as stress, a skin injury, strep throat, medication, or an infection.
How to Treat:
The first step to treating guttate psoriasis is by treating the underlying condition a person is experiencing. Antibiotics may be used if the cause is from a bacterial infection. Your doctor may also feel it necessary to prescribe oral medications, steroid creams, or even light therapy.
5. Erythrodermic Psoriasis
This rare type of psoriasis, also known as exfoliative psoriasis, appears like a severe burn, and is so serious, it can even be seen as a medical emergency. Hospitalization may become necessary as areas affected by this psoriasis may make you unable to control your body’s temperature.
This type of psoriasis is red, scaly, and often widespread, covering large areas of the body. As opposed to the small scales that exfoliate with more common types of psoriasis, in erythrodermic psoriasis this occurs in large portions of the skin.
Erythrodermic psoriasis develops from:
- Bad sunburn
- Uncontrolled plaque psoriasis
- Pustular psoriasis
- Extreme stress
- Sudden stop of using systemic psoriasis medication
How to Treat:
Someone living with this extreme psoriasis usually needs hospitalization. While in there, a combination of remedies most likely to be used until symptoms lessen are: prescription oral medications, topical steroid applicants, and medicated wet dressing.
If you believe you have erythrodermic psoriasis, please consult your doctor and make appointment, as this may be a serious medical emergency.
