Severe psoriasis can significantly increase a patient's risk of death, research in the Archives of Dermatology has revealed.
Psoriasis is a common inflammatory disorder that affects the skin and joints.
The study authors say their research suggests that patients with severe psoriasis should receive comprehensive health assessments to enhance preventive health practices, improve overall health and decrease the risk of mortality.
Experts at the University of Pennsylvania School of Medicine found that patients with severe psoriasis had a 50% increased risk of death compared with patients who did not have psoriasis.
Those with severe psoriasis died an average 3.5 years younger than men without the condition, while women with the same condition died 4.4 years earlier than those without.
Mild psoriasis, however, was not associated with an increased risk of death.
The authors said: "Further studies are necessary to determine the cause of excess mortality in patients with severe psoriasis, how the extent of skin disease affects morality risk and whether the risk of mortality in patients with severe psoriasis is altered by various systemic therapies."
