Given the lack of approved pharmacological agents for this indication and the frequently recalcitrant disease course, therapeutic options are limited.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and methods<\/jats:title><jats:p>Following unsatisfactory therapeutic attempts with other treatment modalities, nine patients (six women; three men) were treated with ustekinumab (45\u00a0mg in individuals &lt;\u00a0100\u00a0kg body weight, 90\u00a0mg in individuals &gt;\u00a0100\u00a0kg) at weeks 0, 4, 12, and 24. Latent tuberculosis was ruled out prior to treatment. Regular follow\u2010up was done at week 4 and 12, and every 12\u00a0weeks thereafter.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Average age at the beginning of treatment was 48\u00a0years. Four patients achieved 75\u00a0% improvement in the palmoplantar Psoriasis Area Severity Index (PASI). Overall, there was an average improvement in the palmoplantar PASI of 71.6\u00a0% after 24 weeks. Two patients exhibited complete resolution after 24 weeks.
