Plasmapheresis in toxic epidermal necrolysis.
BACKGROUND
The treatment of toxic epidermal necrolysis (TEN) is usually based on the removal of the offending drug(s), fluid replacement, nutritional support, and local management. The mortality and morbidity, however, remain high and the death rate may be reduced to 10% only in special centers that use biologic dressings. Plasma exchange (PE) was proven efficacious in small series of patients and of no particular value in others.


METHODS
Seven patients suffering from severe TEN covering 30%-80% of body surface area and having two or four mucous membranes involved, were included in this open study. Malignancy (Hodgkin's disease, brain tumor) and a variety of medicaments (carbamazepine, allopurinol, diphenylhydantoin, cefaclor, amoxicyllin with clavullanic acid) were considered as causally implicated. One to four PEs of 2.5 L were given on alternate days in six patients and on a daily basis in the seventh.


RESULTS
All patients recovered successfully from their disease. No new lesions appeared after the first PE in four patients. Neither adverse reactions from this therapy nor sequelae from TEN were observed after a long follow-up lasting up to 8 years.


CONCLUSIONS
Although PE is expensive and requires easy venous access to be performed, it could be listed in the first line of TEN therapy. The method is safe and efficacious, providing prompt relief from pain and rapid cessation of necrolysis. The alternate day PEs are considered preferable to the everyday regimen.
