Psoriasis bliver i stigende grad omtalt som en "autonom" sygdom, hvor kroppen reagerer imod sig selv. Dette betyder, at immunsystemet fejlagtigt angriber og ødelægger sunde celler og væv, hvilket sætter gang i sygdomsprocessen i kroppen.
Det første udbrud opstår normalt når man er 15-30 år, og det starter ofte ud med en halsbetændelse. Et par dage efter infektionen vil man opleve mindre røde og dråbeformede knuder i huden, som benævnes guttat psoriasis.
Det udslæt man opleverer første gang er som regel meget karakteristisk for sygdommen og de fleste læger vil være i stand til at diagnoticere sygdommen ved første øjekast.
Der er flere ting, der kan påvirke udbrud af psoriasis. Klimaet er en faktor, der både kan lindre eller udløse tilstanden. Koldt vejr vil ofte forværre sygdommen, mens sol og varme kan lindre og reducere symptomerne, hvorfor mange personer med psoriasis foretrækker at leve under varmere himmelstrøg.
En anden faktor, der kan udløse psoriasis er hudskader. Alle skader på huden eller negle, såsom sår- eller slagskader kan føre til at der dannes psoriasis omkring det beskadigede område. Udslættet opstår normalt, når området omkring skaden hæves. Noget man også kalder Koebners-fænomenet.
Alkohol, stress og psykisk stress er andre faktorer, der kan udløse et udbrud, og dette bør så vidt muligt undgås.
Visse lægemidler såsom beta-blokkere og lithium kan også fremkalde eller forværre et psoriasisudbrud.
Udbrud af psoriasis kan afhjælpes ved medicin, sol og lysbehandling. Nedenfor er en beskrivelse af disse forskellige behandlinger:
Sol og saltvand kan ofte hjælpe mod sygdommen. En 3-ugers årlig rejse til et varmt land, hvor man kan sole sig og bade vil i de fleste tilfælde have positiv effekt på sygdommen.
For de personer, der har psoriasis i en moderat form vil det ofte være tilstrækkelig at bruge cremer og salver til at holde sygdommen på afstand. Cremerne reducerer inflammation, rødme og smerter, og skal indeholde kortikosteroider eller vitamin D-lignende stoffer eller en kombination af disse.
En vigtig del af behandlingen for mennesker med psoriasis er lysbehandling fra specialbyggede solarier, der udsender UVB-lys. Disse solarier adskiller sig fra almindelige solarier ved, at de kun udsender kortbølget ultraviolet lys, som har en meget gavnlig effekt på udslæt. De normale UVA-solarier, som folk benytter for at få lidt kulør, producerer generelt langbølget ultraviolet lys, som har ringe effekt på psoriasis og udslæt.
Psoriasis can be worrying, especially when you see your child struggle with itching or discomfort.
For most kids, psoriasis is limited to just a few patches that usually respond well to treatment. More serious cases might need more aggressive treatment. But the good news is that there are many options. If one treatment doesn't work, another probably will.
Psoriasis (suh-RYE-uh-sus) is a non-contagious disease that causes skin cells to build up on the surface of the skin, forming itchy red raised areas (plaques) and thick scales. It can appear anywhere on the body but is most commonly found on the scalp, knees, elbows, and torso.
Psoriasis is a long-lasting (chronic) condition that can get better or worse, seemingly at random. It may go away completely before suddenly reappearing.
For many kids, psoriasis is just a minor inconvenience; for others, though, it can be quite serious. Psoriasis can lead kids to feel self-conscious about their appearance. Sometimes that affects their emotions, and some kids may develop low self-esteem and even depression as a result.
Right now, there's no cure for psoriasis, but a number of good options are available to treat the symptoms. Lifestyle changes, such as maintaining a healthy diet and weight, also can help ease the symptoms.
Doctors aren't sure why people get psoriasis, but they do know how the disease works. White blood cells known as T lymphocytes or T cells are part of the immune system. They travel through the bloodstream fighting off bacteria, viruses, and other things that cause illnesses. When someone has psoriasis, however, T cells attack healthy skin as if they were trying to fight an infection or heal a wound.
Skin cells, which are made deep in the skin, normally take about a month to rise to the surface, where they die and are sloughed off. When psoriasis triggers T cells to attack healthy skin, the immune system responds by sending more blood to the area and making more skin cells and more white blood cells. This forces skin cells to rise to the surface in a few days instead of a month. The dead skin and white blood cells can't be shed quickly enough, and they build up on the surface of the skin as thick, red patches. As the skin cells die, they form silvery scales that eventually flake off.
Psoriasis isn't contagious. Some people inherit the genes that make them susceptible to having it. Many with psoriasis have an immediate family member who also has the disease.
Risk factors that can increase the chances of psoriasis outbreaks include:
- Infections.Strep throat, colds, and other infectious diseases trigger the body's immune system to respond, making a psoriasis outbreak more likely.
- Obesity. The plaques that are produced by many kinds of psoriasis often develop in folds of skin.
- Certain medicines. Lithium, beta-blockers for high blood pressure, and drugs used to prevent malaria have been shown to increase the risk of psoriasis.
- Stress. High stress levels can have an effect on the body's immune system and can make psoriasis symptoms worse.
- Skin irritations. Cuts, scratches, sunburns, rashes, and other irritations that affect the skin can make a psoriasis outbreak more likely.
- Cold weather. In the winter, kids generally spend more time indoors and get less sun. A moderate amount of direct sunlight can help to improve psoriasis.
People with psoriasis will most likely have one or more of these symptoms:
- raised red patches of skin that can have silvery scales on them
- dry, cracked skin that may bleed at times
- itching, soreness, or a burning sensation in the affected area
- thick, pitted fingernails
There are many different types of psoriasis that all have their own symptoms. Common types include:
- Plaque psoriasis. By far the most common type of psoriasis, this causes dry red patches (plaques) and silvery scales. Plaques can appear anywhere on the skin but most often are on the knees, elbows, lower back, and scalp. They can be itchy and painful and may crack and bleed.
- Guttate psoriasis. This most often affects people younger than 30 and often shows up after an illness, especially strep throat. It causes small red spots, usually on the trunk, arms, and legs. Spots also can appear on the face, scalp, and ears or where someone had plaque psoriasis.
- Pustular psoriasis. This type of psoriasis causes the skin to become red, swollen, and covered with pus-filled bumps. Usually, this is on the soles of the feet or the palms and fingertips. Sometimes, though, it covers large areas of the body. This is known as generalized pustular psoriasis, and can sometimes be accompanied by fever, chills, severe itching, and fatigue.
- Inverse psoriasis. This causes smooth, raw-looking patches of red skin that feel sore. The patches develop in places where skin is touching skin, such as the armpits, buttocks, upper eyelids, groin and genitals, or under a woman's breasts.
- Erythrodermic psoriasis. This type of psoriasis is rare. It can cause a bright red rash that covers the entire body, making the skin look as if it has been burned. It's often accompanied by intense itching and pain, a fast heartbeat, and an inability to maintain a proper body temperature.
Usually, diagnosis of psoriasis is fairly straightforward. The doctor will physically examine your child's skin, scalp, and nails and ask you and your child some questions. The doctor may ask if anyone in your family has psoriasis and if your child recently had an illness or started a new medication.
On rare occasions, the doctor may remove a skin sample (do a biopsy) to examine it more closely. A biopsy can tell the doctor whether it's psoriasis or another condition with similar symptoms.
There are lots of ways to treat psoriasis, and different things work for different people. Be sure to talk with a doctor to figure out what treatments work best for your child.
Psoriasis treatments fall into three categories:
- Topical treatments are creams, lotions, and ointments applied directly to the skin. These include moisturizers, prescription corticosteroids and vitamin D creams, and shampoos made with salicylic acid or coal tar. Topical treatments can effectively treat many types of mild to moderate psoriasis, but can be a little messy.
- Light therapy(phototherapy) involves using natural or artificial ultraviolet (UV) light to treat the psoriasis symptoms. A doctor may recommend brief daily exposure to the sun, but too much sunlight can make psoriasis worse. More aggressive forms of light therapy include using controlled doses of UV light on the affected skin, laser therapy, and therapies that combine UV light with medicines and topical treatments.
- Oral or injected medications are used to treat severe psoriasis or psoriasis that resists other treatments. They include pills, shots, and medicines given intravenously (through an IV into a vein). Some of these can have serious side effects and might be prescribed for short periods of time only.
A doctor might try one therapy and then switch to another, or recommend a combination of therapies. It's not always easy to find a therapy that works, and sometimes what works for a time will stop being effective. It's important to work closely with the doctor to stay on top of your child's treatment.
