Several reports show that the safest treatment for psoriasis may be a combination of a vitamin D ointment (1) and oral antibiotics (2). Psoriasis means that you make too much skin because your immunity is overactive. We do not know if an infection is the trigger of the overactive immunity. New skin cell is laid down at its innermost part. Then another cell is laid down underneath that. As each successive new cell is laid down underneath it, the cell over it moves outward, until it is shed as dander or dandruff 28 days later. Psoriasis means that the skin turns over seven times as fast as normal so cells are shed after only four days, instead of the usual 28. This causes thick plaques to form on top of the skin, particularly at the elbows and knees and the face and scalp develop thick scales, and the nails thicken and grow very fast. So, all treatments for psoriasis are aimed at slowing skin turnover rate to normal.

The most common treatment includes cortisone-type ointments, but continued use can cause irreversible thinning. Doctors prescribe light treatments and drugs that sensitize the skin to sunlight (3), but they can cause skin cancer, even the deadly melanoma (4), many years later. Surprisingly, inexpensive commercial tanning parlors may be as effective in treating psoriasis as the highly expensive PUVA treatment administered by dermatologists (5). For severe psoriasis, doctors use poisons, such as methotrexate, but sulfasalazine is far safer, even though it is not as effective (6).

Psoriatic arthritis is very difficult to treat. I often prescribe sulfasalazine 1000 mg T.I.D. plus cephalexin 500 mg twice a day plus Cordran tape on the lesions. For severe cases, the treatment of choice is probably cyclosporine 250 mg per day, but it is loaded with potential side effects (7). Vitamin D ointment slows skin turnover and is not a poison. It is applied to the thick psoriatic plaques at bedtime and covered with special plastic wrap. Rapid spread of psoriasis is usually caused by infection, so doctors often prescribe antibiotics, such as cephalosporins, to kill staph and strep two germs that commonly cause psoriasis to worsen. There is no effective treatment for nails deformed by psoriasis. The most effective is 5% 5-fluorouracil cream applied nightly for several months.
