PUVA therapy combines the healing power of plants with the invigorating effect of sunlight. The essence of the method is a combination of substances of plant origin - psoralen (P) and ultraviolet radiation (UVA). Psoriatic plaques occur due to increased cell division of the epidermis. Young cells do not have time to go through the normal cycle of development and maturation, the result of which are scaly layers that leave when peeling. The goal of PUVA therapy is to inhibit excessive cell division, reduce plaque formation and cause their regression. Installations designed for PUVA therapy are a cabin or a screen, on the inner wall of which are mounted special fluorescent lamps that produce long-wavelength UVA radiation. PUVA devices have various modifications, allowing patients to perform procedures in a lying or standing position, to irradiate separately the head, legs, palms, soles.
There are several types of PUVA therapy:
Systemic PUVA. 1-2 hours before the intended procedure, a psoralen tablet is taken, the dose of which is selected in accordance with the weight of the patient. It is recommended to take the medicine at least an hour after a meal. About 30% of patients experience nausea, so the medicine can be taken with certain foods, such as cheese, milk. Psoralen begins to act after 1 hour, and reaches a peak of action after 2-3 hours, then its activity gradually decreases until it is finally eliminated from the body within a day. After passing the allotted time (usually after 1.5-2 hours), the patient enters the phototherapy booth and undergoes the necessary treatment. The duration of phototherapy (i.e., being in the cockpit) increases gradually. Procedures are carried out 2-4 times a week. It is recommended that there is a break of at least 48 hours between treatments. Treatment continues until a noticeable healing of the rash is observed, gradually reducing the frequency of procedures. Typically, the course of treatment consists of 15-20 procedures, but each case is individual and further treatment tactics are discussed with a dermatologist. Dark sunglasses must be worn all day after the procedure, as the medicine acts on the body for 24 hours.
PUVA baths. They are used both for the whole body and locally (for example, only for arms or legs), on the basis of this, a solution of the required concentration is prepared. Being in the bath lasts 15-20 minutes, immediately after which the procedure is performed. The advantage of PUVA baths is that there is no need to wear dark glasses, in addition, the medicine does not work systemically and there is less chance of harming the liver.
PUVA cream. Most often used for limited areas of skin lesions. It must be applied to the rash 1 hour before phototherapy.
Advantages of PUVA baths, PUVA cream - there is no systemic effect of the drug, so procedures can be performed for pregnant women. When conducting local PUVA therapy, psoralen is excreted within 2-3 hours, there is no need to wear dark sunglasses and apply additional measures of protection against solar UV rays.
