Myth: Systemic steroids cause pustular psoriasis
The advent of biologic therapy for psoriasis has changed the landscape of treatments offered to patients. Nevertheless, systemic therapies still play an important role, according to the American Academy of Dermatology psoriasis treatment guidelines, due to their oral route of administration and low cost compared to biologics. They are options for patients with moderate to severe psoriasis that is unresponsive to topical therapies or phototherapy. However, many dermatologists feel that it is inappropriate to prescribe oral steroids to psoriasis patients due to the risk for steroid-induced conversion to pustular psoriasis, the long-term side effects of steroids, and deterioration of psoriasis after withdrawal of steroids.
Pustular psoriasis appears clinically as white pustules (blisters of noninfectious pus) surrounded by red skin. The pus consists of white blood cells. There are a number of triggers in addition to systemic steroids, such as internal medications, irritating topical agents, overexposure to UV light, and pregnancy. Stopping an oral steroid abruptly can cause serious disease flares, fatigue, and joint pain.
Westphal et al described the case of a 70-year-old woman with palmoplantar psoriasis who was diagnosed with acute generalized exanthematous pustulosis that was treated with corticotherapy by injection and then oral prednisone. She experienced improvement, but her symptoms worsened when she was in the process of reducing the prednisone dose. The dose was increased again, and the same worsening of symptoms was experienced when the dose was reduced. After completely abandoning oral steroid therapy, she developed a severe case of generalized pustular psoriasis that was treated with acitretin. This case illustrates the dangerous consequences of abruptly discontinuing oral steroids.
However, dermatologists may be using oral steroids for psoriasis more often than treatment guidelines suggest. In 2014, Al-Dabagh et al evaluated how frequently systemic corticosteroids are prescribed for psoriasis in the United States. The researchers reported, "Despite the absence or discouragement of systemic corticosteroids in psoriasis management guidelines, systemic corticosteroids are among the most common systemic treatments used for psoriasis." They found that systemic corticosteroids were prescribed at 650,000 of 21,020,000 psoriasis visits, of which 93% were visits to dermatologists. Prednisone was the most commonly prescribed systemic corticosteroid, followed by methylprednisolone and dexamethasone. To prevent rebound flares, systemic corticosteroids were prescribed with a topical corticosteroid in 45% of the visits in patients with psoriasis as the sole diagnosis. They concluded, "The striking contrast between the guidelines for psoriasis management and actual practice suggests that there is an acute need to better understand the use of systemic corticosteroids for psoriasis."
The benefits of systemic corticosteroids versus the frequency of adverse reactions should be weighed by dermatologists and patients to make evidence-based decisions about treatment. Patients should take oral steroids exactly as prescribed by physicians.

When I was a resident, I was trained not to use systemic steroids in psoriasis patients for the reasons noted above, and I have faithfully followed these instructions 9 years into practice. However, I see many patients with severe psoriasis who are given systemic steroids by other physicians (ie, rheumatologists for psoriatic arthritis, pulmonologists for asthma). I often tell patients afterwards of the dangers of systemic steroids and to have them tell their other doctors to be cautious when giving another course of systemic steroids. However, I have yet to see a generalized pustular psoriasis outbreak or flare in psoriasis vulgaris after a course of systemic steroids. While I do not recommend systemic steroids for psoriasis patients since we have so many other systemic agents, I wonder if the risks that we were all trained about are really that high.

How bad is it to give patients with psoriasis systemic steroids? Are psoriasis patients treated with systemic steroids likely to get a pustular flare? Are patients with psoriasis who suddenly stop their corticosteroids more likely to get a pustular flare than psoriasis patients who suddenly stop other systemic psoriasis treatments? I don't have the answers to these questions. My sense is that we have a lot of dogma and strong opinions but very little hard evidence to answer these questions.
I don't typically prescribe systemic steroids to psoriasis patients, but systemic steroids are widely used. Sometimes there are problems. I have seen patients who received systemic steroids for psoriasis and who went on to have a pustular flare, but it's possible the systemic steroid was given because those patients were headed toward the pustular flare already.
I once had a psoriasis patient who came to see me with a suddenly inflamed tender joint. Not knowing what to do, I called a rheumatologist to see the patient. The rheumatologist, too busy to work the patient in, told me to give the patient a 2-week prednisone taper. I did, and nothing untoward happened with the psoriasis. This one anecdote doesn't give me much confidence that systemic steroids are safe for psoriasis patients.
Clearly, long-term steroids cause a host of problems (eg, osteoporosis, diabetes). But I'm not sure that the dogma that systemic steroids should be avoided in patients with psoriasis is well supported. Systemic steroids are being widely used, and I don't see an epidemic of pustular flares.
Is it a mistake to give systemic steroids to psoriasis patients? I just don't know.
