1. Understand It Is a Vicious Cycle
One of the more uncommon forms of psoriasis, pustular psoriasis is characterized mainly by pus-filled blisters over reddened skin. Neither infectious nor contagious, this abrupt skin condition can be localized (covering only one area of the body) or generalized (covering almost anywhere on the body, though mainly in the armpits, backs of knees, groin and insides of elbows). Pustular psoriasis develops in a cycle that repeats over a few weeks. First the skin reddens, followed by the formation of pustules and then scaling of the skin. This form of psoriasis is uncommon in children.
2. Location, Location, Location
There are three types of pustular psoriasis, dependent on where the pustules are found. Palmo-plantar psoriasis (found on hands and feet) and acropustulosis (pustules on ends of fingers or toes) are much less common than generalized pustular psoriasis, or von Zumbusch psoriasis, named after dermatologist Leo Ritter von Zumbusch. Along with itching, this form can be accompanied by chills, fever, dehydration and other severe symptoms. In older people, stress on the heart or kidneys from untreated pustular psoriasis can be life-threatening.
3. Stopping This May Start It All
In many cases, a direct cause of pustular psoriasis cannot be determined. However, as with most types of psoriasis, pustular psoriasis can at times be linked to particular factors that trigger this psoriasis. One leading cause of pustular psoriasis is stopping suddenly the taking of oral or injected steroid medications used in the treatment of another medical condition. So apparent is this link that it has been suggested to discuss the taking of steroid medications with a dermatologist should they be prescribed for any condition.
4. Other Roads Leading to Pustular Psoriasis
As psoriasis has been determined to be the result of white cells called T lymphocytes treating healthy skin cells as foreign bodies, some infections can trigger pustular psoriasis. Reactions to other types of medications including iodine, lithium and some blood pressure medications, beta-blockers and antidepressants can be risk factors. Certain medical conditions such as hypocalcemia (low calcium in the blood) and cholestatic jaundice have been known to trigger pustular psoriasis. Even pregnancy can be a factor in the development of this condition.
5. Soothing the Skin
As pustular psoriasis has the potential to be life-threatening, it is suggested that medical treatment always be sought. Hospitalization may often be required for treatment of possible dehydration and administration of antibiotics. Topical corticosteroids, ultraviolet (UV) light therapy (combined with oral psoralens to make skin more light-sensitive) and drugs used to suppress the immune system and reduce skin inflammation are all treatment choices. Steroids may be used to treat severe cases, but are not normally used due to the link between the stoppage of these drugs and the onset of this condition.
