Patients with palmoplantar psoriasis have more physical disability and discomfort than patients with other forms of psoriasis: implications for clinical practice.

BACKGROUND: Psoriasis is a chronic, unpredictable, and incurable disease that has a negative impact on patients' quality of life. Palm and sole psoriasis can add to this negative impact as it directly affects activities of daily living.

OBJECTIVE: We sought to estimate the prevalence of palmoplantar psoriasis in a patient population and to explore associations with patient outcomes.

METHODS: In all, 317 individuals with psoriasis completed a comprehensive assessment battery. Patients with palmoplantar psoriasis (n = 124, 39%) were compared with patients without palmoplantar involvement with respect to functional disability, psychiatric symptoms, physical and social discomfort, self-reported psoriasis severity, and health-related quality of life.

RESULTS: Patients with palmoplantar involvement reported significantly greater physical disability and physical discomfort than patients without palmoplantar involvement (both P <.01). There were no differences between the 2 groups with respect to psychosocial outcomes.

CONCLUSION: Patients with palmoplantar psoriasis are affected to a greater degree by the physical aspects of the disease than patients without palmoplantar involvement.
