Include quality of life measures in evaluating treatment success of psoriasis

 

No matter what the disease, physician judgment of disease severity correlates poorly with the patient’s quality of life, Dr. Joel Gelfand said during a presentation at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.

“Patients with similar objective findings have varying health-related quality of life,” said Dr. Gelfand, professor of dermatology at the University of Pennsylvania, Philadelphia.

Quality of life research was underway in the 1970s, but studies on quality of life for psoriasis patients didn’t start to take off until the mid- to late 1990s, Dr. Gelfand pointed out. The research has shown that even patients with mild psoriasis can suffer significant impairments in quality of life, and quality of life should be an important consideration in treatment decisions, he said.

Dermatologists have several tools to measure quality of life and treatment, with varying levels of validation. For example, the Psoriasis Symptom Inventory measures symptoms including redness, itching, scaling, burning, stinging, cracking, flaking, and pain (J Dermatolog Treat. 2013 Oct;24[5]:356-60).

The Dermatology Life Quality Index (DLQI) is commonly used in clinical trials of psoriasis therapeutics and is frequently used in clinical practice in Europe, Dr. Gelfand said. The DLQI asks about symptoms, feelings, daily activities, leisure time, work/school functioning, and relationships, as well as the treatment itself.

He and his associates used this tool in a study of psoriasis patients seen in routine clinical follow-up in dermatology practices across the United States. The study found that approximately 19% of those who were almost clear (compared with 2% of those who were clear) met DLQI criteria for a treatment change (J Am Acad Dermatol. 2014 Oct;71[4]:633-41). European guidelines, he added, suggest that patients achieving a Psoriasis Area and Severity Index (PASI) score between 50 and 75 and a DLQI greater than 5 should modify their treatment regimens (Arch Dermatol Res. 2011 Jan; 303[1]: 1-10).

Dr. Gelfand described his clinical approach to psoriasis and evaluating quality of life in patients, which involves a global assessment (conducted by a medical assistant) with both a physical and emotional component.

First, patients are asked to think about how severe their physical symptoms of psoriasis have been over the past week on a scale of 0-10, with 0 being no symptoms and 10 being the worst. Next, patients are asked to think about how severe their psoriasis-related emotional symptoms (such as embarrassment, frustration, depression) have been over the past week on a scale of 0-10, with 0 being no symptoms and 10 being the worst. The patient’s responses help direct treatment plans.

Another reason to attend to quality of life in psoriasis patients: suicide risk. Suicide risk in psoriasis patients has not been well studied, said Dr. Gelfand, whose PubMed search of “psoriasis and suicide” in September yielded only 48 hits. However, one study of 217 patients who completed the Carroll Rating Scale for Depression showed that almost 10% reported a wish to be dead, and almost 6% reported active thoughts of suicide (Int J Dermatol. 1993 Mar;32[3]:188-90).

Another large study that used data from the National Health Service in England included 119,304 patients with psoriasis and found a high risk for suicide attempts and/or suicide in these patients (J R Soc Med. 2014 Feb 13;107[5]:194-204). High risk also was noted for patients with eczema, diabetes, epilepsy, asthma, and inflammatory joint disease, he said. In addition, the Centers for Disease Control and Prevention’s research on suicide risk factors includes medical conditions such as psoriasis, as well as demographic factors with rates being higher in middle-aged white males.
