Abstract
Erythrodermic psoriasis (EP) is a severe form of psoriasis that may be associated with serious and sometimes fatal complications. The treatment of EP is often a challenge, since several factors, including treatment failure or possible complications, may limit favorable outcomes with traditional drugs. Recent evidence suggests that biological drugs, including both anti-tumor necrosis factor alpha agents and ustekinumab, may be useful in improving the management of EP. Unfortunately, since subjects with EP are usually excluded from pivotal trials involving biological agents, this evidence is currently dispersed in small case series and single case reports. In this paper, we briefly analyze conventional therapies for EP, before going on to critically evaluate the existing clinical evidence for the role of current biological drugs, namely infliximab, etanercept, adalimumab, and ustekinumab. Finally, we discuss the potential benefits that newer/developmental biological agents could bring to the management of EP.
