What Injections Or Infusions Are Available For Psoriasis

Recently, a new group of drugs called biologics have become available to treat psoriasis and psoriatic arthritis. They are produced by living cells cultures in an industrial setting. They are all proteins and therefore must be administered through the skin because they would otherwise be degraded during digestion. All biologics work by suppressing certain specific portions of the immune inflammatory response that are overactive in psoriasis. A convenient method of categorizing these drugs is on the basis of their site of action:

Drug choice can be complicated, and your physician will help in selecting the best option. In some patients, it may be possible to predict drug efficacy on the basis of a prospective patient’s genetics. It appears that the presence of the HLA-Cw6 gene is correlated with a beneficial response to ustekinumab.

Vitamin D Analogues: How They Help

Vitamin D analogues are used to help control overactive skin cell production by binding to the vitamin D receptors on the skin cells.

Topical vitamin D analogues such as:

• calcitriol

are effective at slowing the growth of the skin cells and can be used with emollients and topical corticosteroids applied to the skin.

Calcipotriene with betamethasone is a vitamin D analogue that is already combined with an antiinflammatory corticosteroid. Brands include: Taclonex, Taclonex Scalp, Wynzora and Enstilar.

The most common side effect with these agents is mild skin irritation. Some topical vitamin D analogues may take up to 6 to 8 weeks for their full effect.

Oral calcitriol can also be used for psoriasis.

Reviewing Treatment With Topical Medications

If you are an adult, your healthcare professional should arrange a review appointment 4 weeks after you start a new topical treatment. Children should have a review appointment 2 weeks after starting a new topical treatment.

If there is little or no improvement at this review, your healthcare professional should discuss the next treatment option with you and check if there are any reasons why the treatment is not working.

If your psoriasis is responding to topical treatment your healthcare professional should discuss with you:

• the importance of continuing treatment until your psoriasis improves or for the length of time recommended

• that relapse occurs in most people after treatment is stopped

• that after the initial treatment period topical treatments can be used as and when you need them to control your psoriasis.

You should be offered a supply of your topical treatment to keep at home to use yourself as needed.

If you are an adult and have been using potent or very potent corticosteroids, your healthcare professional should offer you annual once-yearly review to check for problems. Children and young people who have been using corticosteroids of any strength should also have their treatment reviewed once a year.

The Goal Of Treatment: Satisfaction With Treatment And Outcome

Defining treatment goals determines adherence, manages expectations, and avoids treatment failures. Goals are important to provide patients with short- and long-term perspectives for their disease. The ultimate goal of psoriasis treatment is the complete clearance of all skin symptoms however, realistically, it is not possible to achieve this in all patients and/or cannot be permanently maintained because psoriasis is a chronic and recurring disease. Whereas a PASI 75/90/100 improvement and the more recently established absolute PASI 2 or Physician Global Assessment 0/1 are commonly used outcome parameters in clinical trials, those severity parameters are not regularly assessed by all physicians in daily practice for cases of mild-to-moderate psoriasis.

We are in consensus that patient satisfaction should be considered the primary criterion when assessing the goals and success of treatment.

In daily practice, the assessment of patient satisfaction can be done by asking a question that requires a simple answer Yes or No as to whether a patient is satisfied with the treatment or treatment outcome. If a patient is not satisfied, and before deciding on the next step, i.e., to continue or change the treatment, it is recommended that the cause of discontent be explored further by examining the following aspects:

Clinical Manifestation Of Psoriasis

Psoriasis is a chronic, inflammatory, multi-system disorder characterized by abnormal epidermal differentiation and hyperproliferation thought to be related to abnormal immune system activity. According to data from various resources, about 2-3% of the general population suffers from psoriasis. Accepting and extrapolating these rates globally, approximately 140 to 210 million people live with psoriasis Although psoriasis is usually benign, it is a lifelong illness with remissions and exacerbations and is sometimes refractory to treatment. Nonetheless, the majority of the cases are mild or moderate psoriasis . A recent study observed 75.8% of patients to have a psoriasis area severity index of < 20 . Moreover, 17-55% of patients experience remissions of varying lengths. Plaque-type psoriasis is the most common form, affecting 80 90% of patients. Inverse, erythrodermic, pustular and guttate forms of psoriasis have also been described. Patients present with sharply demarcated, erythematous plaques covered by silvery white scales, most commonly on the extensor surfaces and the scalp. The natural history is variable but is often chronic and relapsing, and patients may experience extracutaneous manifestations commonly including nail involvement and psoriatic arthritis in up to 20% of patients .

What Are Other Types Of Psoriasis

Plaque psoriasis is the most common type. About 80% to 90% of people with psoriasis have plaque psoriasis.

Other, less common types of psoriasis include:

• Inverse psoriasis appears in skin folds. It may look like thin pink plaques without scale.
• Guttate psoriasis may appear after a sore throat caused by a streptococcal infection. It looks like small, red, drop-shaped scaly spots in children and young adults.
• Pustular psoriasis has small, pus-filled bumps on top of the red patches or plaques.
• Sebopsoriasis typically appears on the face and scalp as red bumps and plaques with greasy yellow scale. This type is a cross between psoriasis and seborrheic dermatitis.

Topical Treatment For Trunk And Limb Psoriasis In Adults

If you have psoriasis of the trunk or limbs you should be offered a potent corticosteroid and a vitamin D preparation as initial treatment. Each treatment should be applied once a day and should be used for up to 4 weeks.

If this does not improve or control your psoriasis, you should be advised to stop using the potent corticosteroid and apply only the vitamin D preparation twice a day for up to 8 weeks.

If the vitamin D preparation does not improve or control your psoriasis after 8 to 12 weeks, you should be offered one of the following treatments:

• a potent corticosteroid to apply twice a day for up to 4 weeks or

• a coal tar preparation applied once or twice daily or

• a combined product containing a potent corticosteroid and vitamin D applied once a day for up to 4 weeks.

If these treatment options don’t control your psoriasis, you may be referred to a specialist who may offer you other topical treatments, or other treatment options depending on how extensive your psoriasis is and the impact the psoriasis is having on your life.

For some forms of localised psoriasis where other treatments have not been successful, your healthcare professional may offer you ‘short-contact’ dithranol ointment or cream. To ensure it is applied correctly, you should be given educational support to help you apply it yourself or treatment should be given in a specialist setting.

Is Psoriasis The Same As Eczema

Psoriasis and eczema are two different skin conditions. They differ in where the disease appears on the body, how much it itches and how it looks. Eczema tends to appear more often behind the knees and inside the elbows. Eczema also causes more intense itching than psoriasis. Many people, especially children, can get both eczema and psoriasis.

Immunomodulators Basic Concept Of Drugs Used To Treat Psoriasis

In a homeostatic situation, the immune system interacts with many antigens without notice in a healthy individual . However, the development of a hypersensitivity response induced by the chronic stimulation of the immune system results in the clinical manifestation of a specific group of illnesses . The lack of control of the immune response is the basis of the clinical manifestation of these diseases. In the majority of these cases, there is an increase in the immune response activity. Therefore, the manifestation of a hypersensitivity reaction induces the pathogenesis of autoimmune and other inflammatory diseases .

The basic approach for treatment of these illnesses is manipulating the immune system to reduce its activity. In these cases, the therapeutic goal is fine-tuning of the milieu to downgrade the pathological response and return the immune system to a state of controlled homeostasis . However, the modulation of the system has to bring the balance to its normal limits without reducing it beyond these boundaries. It can be compared to adjusting the volume and the tone of music in an orchestra. High volume and distortions reduce the beauty of the music and can cause discomfort. In adjusting the volume and correcting the distortions, the maestro modulates the music, creating a pleasant sensation while still ensuring that each component remains audible.

How To Use Corticosteroids Safely

Topical corticosteroids are used to reduce inflammation and are available in different strengths, for example they can be mild, moderate, potent and very potent. Very potent corticosteroids should not be used to treat psoriasis in children or young people. In adults very potent corticosteroids should only be used in specialist care. This treatment needs to be carefully supervised and should only be used for up to 4 weeks.

Potent and very potent corticosteroids should not be used on the face, flexures or genitals.

It is important that you follow the advice given to you about how to use each topical corticosteroid because they can sometimes cause side effects and could even make your psoriasis worse. Your healthcare professional should explain the possible side effects and how to avoid them. If you are using potent or very potent steroids you should have a 4-week break between courses of treatment to prevent you developing side effects. You may be given a different non-steroidal topical treatment to use during this break, such as vitamin D or coal tar.
