BACKGROUND AND DESIGN: Patient preferences for health outcomes can be explicitly assessed and expressed in quantitative terms known as utilities. Three standard methods for utility assessment have been used to quantify patient preferences, but these methods have not previously been applied to skin disease. Eighty-seven patients with psoriasis from a tertiary medical center were interviewed, using an interactive, computer-based utility assessment questionnaire, U-Titer. Utilities for three categories of psoriasis severity and potential adverse outcomes of methotrexate therapy were assessed by the vertical rating scale, time trade-off, and standard gamble. RESULTS: Patients assigned a broad range of utilities for each of the health states. Utilities obtained by the vertical rating scale did not correlate well with utilities obtained by standard gamble or time trade-off methods. However, utilities assessed by standard gamble and time trade-off were not significantly different. Patient characteristics such as age, gender, and education were not correlated with utility and did not explain the variation. Indicators of the patients' disease severity were not predictive of utilities for the assessed health states. The relatively high utility for liver biopsy suggests that there is less patient aversion to the procedure than suspected. CONCLUSIONS: Utilities, or quantitative measures of patient preferences for health states, are measurable and vary widely for mild, moderate, and severe psoriasis and possible adverse outcomes of methotrexate treatment. The process of elucidating individual patient utilities for various health outcomes can be used to incorporate patient preferences into the process of clinical decision making. Guidelines that are based solely on severity of symptoms, without input from patients on how they value such symptoms, must be questioned.

Fibrosis of the liver developed to a degree that contraindicated further treatment with methotrexate in 11 of 43 patients who had been receiving maintenance therapy with methotrexate for psoriasis. Liver biopsy had been performed prior to initiation of methotrexate therapy and was repeated at 12- to 18-month intervals. In this retrospective study, age of the patient and duration of therapy have been found to be significant factors in those patients receiving only the weekly oral dosage schedule. Yearly biopsies of the liver are recommended for patients who receive methotrexate throughout their courses of therapy.

An unusual case of adenomatous hyperplasia of the liver arose spontaneously in an 82-year-old woman. Massive fatal ascites developed during an eight-week period in the absence of cirrhosis. No drug, chemical, or hormone could be identified as the causative agent. Estrogens may play a role as possible promoters in the growth of hepatic tumors. Identifying liver tumors in women that are not associated with oral contraceptive use is valuable.
