    Notes: Background  Acne is a common skin disorder with a significant psychological and social impact for some people. Little is known about how personality and emotional traits affect acne and its impact on quality of life and treatment. Trait anger (TA), which is related to heart disease and other morbidities, may also affect acne and patients' adjustment to it.Objectives  To evaluate the relationship between TA and acne severity, skin-related quality of life, satisfaction with treatment, and adherence to treatment.Participants and methods  A sample of 479 individuals with acne completed a survey instrument to assess acne severity, skin care practices, skin-related quality of life, satisfaction with treatment, adherence, TA and demographic variables. Respondents who reported high TA were compared with individuals with low TA on outcome variables. Regression analyses adjusted for covariates and identified the significant predictors of quality of life, satisfaction and adherence.Results  High TA was unrelated to acne severity (P = 0·2) or frequency of face washing (P = 0·9). Anger was significantly related to both global quality of life (P 〈 0·001) and skin-related quality of life (P = 0·002) as well as to satisfaction with treatment (P = 0·001) and adherence to treatment advice (P = 0·05) in bivariate analyses. Regression analyses revealed that high TA remained a significant predictor of global (P 〈 0·001) and skin-related quality of life (P = 0·003) and satisfaction with treatment (P = 0·04), but not adherence to treatment advice (P = 0·8) after controlling for covariates.Conclusions  Anger is associated with the quality of patients' lives and with their satisfaction with treatment. Care of acne patients should include attention to anger and other chronic emotional states, quality of life, as well as to clinical severity. Simple guidelines are suggested for how clinicians might approach this important aspect of care.

    Notes: Background  Patients are commonly nonadherent to medication regimens. In dermatology, there has been little study of the effect of nonadherence on outcomes.Objectives  To test the association between adherence behaviour and changes in severity of psoriasis.Methods  Twenty-four subjects with psoriasis were enrolled in an 8-week, left/right, controlled trial of salicylic acid plus topical tacrolimus ointment vs. salicylic acid plus placebo. Subjects were given salicylic acid to apply to all lesions. The salicylic acid was supplied in a bottle with a medication event monitoring system cap in order to assess adherence to the salicylic acid. The primary outcome for this study was the relationship between the change in the disease severity (change in sum score of erythema, scale and thickness scores for a target plaque) and medication adherence.Results  The mean initial disease severity was 5·8 on a nine-point sum score scale. For the topical tacrolimus-treated side, a decrease in adherence rate of 10% was associated with a 1-point increase in severity (P 〈 0·05). For the placebo-treated side, adherence was not significantly correlated with changes in severity.Conclusions  Nonadherence may have a significant role in altering clinical trial data, skewing it towards ineffectiveness. Improved outcomes in psoriasis may be achievable through interventions that improve patients' adherence to treatment.

    Notes: Background  Psoriasis has a negative impact on patients' quality of life. Treatment strategies should address both the cutaneous manifestations of the disease and their impact on quality of life.Objectives  To evaluate the effect of alefacept on quality of life in 553 patients with chronic plaque psoriasis.Methods  In this multicentre, double-blind, parallel-groups study, patients were randomized to receive alefacept for two courses, alefacept in course 1 and placebo in course 2, or placebo in course 1 and alefacept in course 2. In each course, alefacept 7·5 mg or placebo was administered once weekly by 30-s intravenous injection for 12 weeks followed by 12 weeks of observation. The Dermatology Life Quality Index (DLQI), Dermatology Quality of Life Scales (DQOLS) and Short Form-36™ Health Survey (SF-36) were administered at baseline, 2 weeks after the last dose in both courses, at the beginning of course 2, and at the end of the observation period in both courses.Results  In course 1, alefacept significantly reduced (improved) mean DLQI scores compared with placebo: 4·4 vs. 1·8 at 2 weeks after the last dose (P 〈 0·0001) and 3·4 vs. 1·4 at 12 weeks after the last dose (P 〈 0·001). Patients who received two courses of alefacept experienced additional enhancement of quality of life measures during the second course. Similar results were observed for the DQOLS. The SF-36 survey confirmed that alefacept had no negative impact on general quality of life.Conclusions  Alefacept improved quality of life in patients with chronic plaque psoriasis and maintained this benefit for at least 12 weeks following cessation of treatment. A second course of alefacept provided additional quality of life benefit.

    Notes: Summary Background  The Eczema Area and Severity Index (EASI) is used by dermatological investigators world-wide to assess eczema disease severity. EASI measures are, however, time-consuming and require trained personnel, thereby limiting its application to large-scale epidemiological studies. Additionally, the use of self-assessed severity indices in dermatology is restricted to adult subjects and conditions, thereby not addressing the needs of paediatric patients. Objectives  To develop and validate an instrument for a caregiver's self-assessment of the severity of his/her child's atopic dermatitis (AD), the Self-Administered EASI (SA-EASI). Methods  Trained investigators performed a modified EASI assessment on the same day as an SA-EASI was obtained from 47 caregivers of children with AD. Results  The SA-EASI was found to be a valid measure of the severity of AD. Total, acute and chronic SA-EASI scores predicted total, acute and chronic modified EASI scores ( P  〈 0·0001). SA-EASI body surface area (BSA) scores predicted EASI BSA scores ( P  〈 0·0001). SA-EASI pruritus scores correlated with the acute, chronic and total EASI scores ( P =  0·0001). Conclusions  The SA-EASI may provide caregivers the means to report the severity of their child's skin disease objectively. The high correlation with the EASI score observed in this sample implies that statistical inferences with the SA-EASI will be valid for large populations. In future studies, this will permit analysis of the relationship of skin disease severity to such measures as quality of life, disability, patient satisfaction and the costs of various therapies. Moreover, this SA-EASI instrument may allow older children, over 12 years old, to assess the severity of their AD.

    Notes: Background  Psoriasis is a chronic disease that significantly diminishes the health-related quality of life (HRQOL). Infliximab is a chimeric, tumour necrosis factor α monoclonal antibody that has been shown to improve the signs and symptoms of plaque psoriasis.Objectives  The objective of this study was to evaluate the effect of infliximab induction therapy on the HRQOL of patients with severe plaque psoriasis.Methods  In this double-blind, placebo-controlled trial, 249 patients were randomly assigned to receive intravenous infusions of 3 or 5 mg kg−1 of infliximab or placebo and were treated at weeks 0, 2 and 6. Patients completed the Dermatology Life Quality Index (DLQI) at baseline and week 10.Results  Infliximab induction therapy resulted in a substantial improvement in HRQOL. At week 10, patients in the infliximab 3- and 5-mg kg−1 groups showed a median percentage improvement in DLQI scores of 84·0% and 91·0%, respectively, compared with 0% in the placebo group (P 〈 0·001). The median decrease from baseline in DLQI score at week 10 was 8·0 and 10·0 for the 3 and 5 mg kg−1 infliximab groups, respectively, compared with 0 in the placebo group (P 〈 0·001). Thirty-three per cent and 40% of patients in the 3 and 5 mg kg−1 infliximab groups, respectively, had a DLQI score of 0 at week 10, compared with 2% in the placebo group (P 〈 0·001). There was a strong correlation between the percentage change from baseline at week 10 in Psoriasis Area and Severity Index (PASI) scores and the percentage change in DLQI scores during the same period (Spearman's correlation, 0·61, P 〈 0·001). When the infliximab and placebo treatment groups were combined, patients with at least 75% improvement in PASI scores between baseline and week 10 had a greater mean improvement in DLQI scores (81%) than those with 50–75% improvement in PASI during the same period (60%).Conclusions  Infliximab induction therapy resulted in significant improvement in HRQOL in patients with severe psoriasis.

    Notes: Background  Melasma can have significant emotional and psychological effects on those affected with the condition. In the past, the impact of melasma on health-related quality of life (HRQoL) has been assessed using general measures of skin disease that equally weigh both the physical and psychosocial distress arising from the presence of a dermatological condition.Objectives  Our purpose was to develop and validate a disease-specific HRQoL instrument to identify the areas of the patient's life most impaired by melasma as well as the effects of the condition on their level of functioning in correlation with disease severity: the Melasma Quality of Life scale (MELASQOL).Patients and methods  A random sample of 102 women identified by an investigator as having melasma were evaluated by the investigator using the Melasma Area and Severity Index (MASI). The patients were then anonymously surveyed with the SKINDEX-16, the Fear of Negative Evaluation scale, the Dermatology Life Quality Index (DLQI), a skin discoloration evaluation questionnaire, and a measure of perceived life quality difference without melasma. The 10-item MELASQOL scale was devised from the comprehensive HRQoL assessment battery.Results  The psychometric properties of the MELASQOL were comparable with the properties of the DLQI and the SKINDEX-16. The MELASQOL scores were highly correlated with the other HRQoL measures. The discriminatory ability of the MELASQOL is superior to the SKINDEX-16 and the DLQI for melasma. The three life domains most adversely affected by melasma (social life, recreation/leisure and emotional well-being) were highlighted by this instrument. These were the same three areas of life that patients believed would improve the most if they no longer were affected by the disease.Conclusions  The MELASQOL can be used to evaluate objectively the effect of melasma on a patient's HRQoL. The high correlation with the DLQI, the SKINDEX-16 and the skin discoloration questionnaire suggests that the new scale is a valid instrument, which can be used to monitor the level of impairment individuals suffer due to their melasma. The MELASQOL scores can help guide treatment methods as well as track the improvement of patients' HRQoL.
