Psoriasis affects around 1.8 million people across the UK. If you live with this condition, you know how it can impact your daily life. The good news is that new treatments are being developed all the time through clinical research.
This guide explains the common symptoms of psoriasis, what causes them, and how you could help advance treatment by joining a psoriasis clinical trial UK study with 4MCS.
What is Psoriasis?
Psoriasis is a long-term skin condition that happens when your immune system becomes overactive. Normally, your body makes new skin cells and replaces old ones every three to four weeks. With psoriasis, this process speeds up to just three to seven days.
This rapid turnover means skin cells build up on the surface before they are ready. The result is raised, scaly patches that can appear anywhere on your body.
Psoriasis is not contagious. You cannot catch it from someone else or pass it on through touch.
Common Psoriasis Symptoms
The symptoms of psoriasis can range from mild to severe. Most people experience periods when their symptoms improve (remission) followed by times when they get worse (flare-ups).
| Symptom | Description |
|---|---|
| Patches of skin | Red, pink or purple raised areas covered in silvery-white or grey scales |
| Itching | Mild to severe itching around affected areas |
| Burning or soreness | Uncomfortable sensations on and around patches |
| Dry, cracked skin | Skin that may crack and sometimes bleed |
| Nail changes | Thick, ridged or pitted nails |
| Joint stiffness | Swollen, stiff joints (may indicate psoriatic arthritis) |
These patches most commonly appear on the elbows, knees, scalp and lower back, but they can develop anywhere on your body.
Types of Psoriasis
Plaque psoriasis is the most common type, affecting around 80% of people with the condition. However, there are several other forms.
Plaque psoriasis causes thick, scaly patches that can cover large areas of skin. This is the type most often studied in clinical trials for psoriasis in UK research centres.
Guttate psoriasis appears as small, drop-shaped patches, often triggered by a throat infection. It commonly affects children and young adults.
Scalp psoriasis affects the scalp, hairline and sometimes extends to the forehead and behind the ears. It can cause fine flaking or thick, crusted plaques.
Inverse psoriasis develops in skin folds such as the armpits, groin and under the breasts. The patches tend to be smooth rather than scaly.
Nail psoriasis causes changes to fingernails and toenails, including pitting, discolouration and separation from the nail bed.
What Triggers Psoriasis Flare-Ups?
While the exact cause of psoriasis is not fully understood, certain triggers can make symptoms worse. Understanding your personal triggers can help you manage the condition more effectively.
Common triggers include:
- Stress and anxiety
- Skin injuries such as cuts, scrapes or sunburn
- Certain medications
- Throat infections
- Cold, dry weather
- Smoking and alcohol
For more detailed information about psoriasis causes and management, the NHS provides helpful guidance on living with this condition.
Current Treatment Options
There is currently no cure for psoriasis, but treatments can help control symptoms and improve quality of life. Treatment usually starts with creams and ointments applied directly to the skin.
If these do not work well enough, doctors may recommend light therapy (phototherapy) or medicines that work throughout your whole body.
The challenge is that what works for one person may not work for another. Many people try several treatments before finding one that helps them. This is one reason why clinical research is so important.
How Psoriasis Clinical Trials Help
Clinical trials test new treatments to see if they are safe and effective. By taking part in psoriasis clinical trials, participants help researchers understand the condition better and develop treatments that could help millions of people.
4MCS is currently running plaque psoriasis clinical trials at our research facilities in Ilford (London) and Swinton (Manchester). These studies look at new ways to treat moderate-to-severe psoriasis.
