Moderate correlation between quality of life and disease activity in adult patients with atopic dermatitis.

BACKGROUND: Studies assessing the relationship between disease activity and quality of life (QoL) in adults with atopic dermatitis (AD), before and after therapy are lacking. The relation between disease activity and QoL in AD patients was evaluated before (t = 0) and after 6 weeks (t = 6) of treatment with cyclosporin 5 mg/kg. METHODS: In 54 patients with severe AD, disease activity was assessed using objective Scoring Atopic Dermatitis index (SCORAD), Six Area Six Sign Atopic Dermatitis (SASSAD), 'rule of nines' extent score and serum levels of thymus and activation-regulated chemokine (TARC). Patients filled out the Dermatology Life Quality Index (DLQI). To study the relation between disease activity and QoL, correlations were calculated and regression analysis was performed. RESULTS: At t = 0 there was a small, non-significant correlation between the DLQI and the objective SCORAD, 'rule of nines' or serum TARC levels. At t = 6 the objective SCORAD, serum TARC and the 'rule of nines' score showed moderate and significant correlations with the DLQI (r = 0.34, P = 0.02; r = 0.31, P = 0.03; r = 0.49, P < 0.001). An individual's improvement in disease activity (objective SCORAD, SASSAD and 'rule of nines') with 10 points was associated with an improvement of 1.3, 1.5 and 1.1 points respectively in DLQI. CONCLUSIONS: Disease activity correlated better with QoL when disease activity was less severe and disease extent ('rule of nines') correlated better with QoL than disease severity. An individual's improvement of 10 points in disease activity was accompanied by only a small improvement in QoL. Other factors than disease activity may influence QoL in patients with AD.

First experience with enteric-coated mycophenolate sodium (Myfortic) in severe recalcitrant adult atopic dermatitis: an open label study.

BACKGROUND: Severe atopic dermatitis (AD) is often treated successfully with oral immunosuppressive drugs such as cyclosporin (CsA) or oral corticosteroids. However, some patients develop adverse effects or are unresponsive to these first-choice oral immunosuppressive drugs. OBJECTIVES: To evaluate whether enteric-coated mycophenolate sodium (EC-MPS) is an effective treatment in patients with severe, recalcitrant AD. METHODS: Ten patients with severe, recalcitrant AD were treated with EC-MPS 720 mg twice daily for 6 months. All patients had to discontinue other oral immunosuppressive drugs due to adverse effects (n = 8) or nonresponsiveness (n = 2). Disease activity was monitored using the Severity Scoring of Atopic Dermatitis (modified SCORAD) index and the Leicester Sign Score (LSS). Additionally, the level of serum thymus and activation-regulated cytokine (TARC) was measured. During treatment, safety laboratory examination was performed. Total serum immunoglobulin E (IgE) was followed during treatment. Use of topical corticosteroids was recorded before and during treatment. RESULTS: Compared with baseline, the mean scores for disease activity significantly decreased during treatment with EC-MPS [modified SCORAD (P = 0.04), LSS severity (P = 0.01), LSS extent (P = 0.01)]. In addition, serum TARC levels and total serum IgE levels significantly decreased after treatment compared with before (P = 0.03; P = 0.05). Disease activity decreased after approximately 2 months of treatment and stabilized during the 6-month treatment period. No differences in the amount of topical corticosteroids used in the 6 months prior to treatment compared with the 6-month treatment period were found (P = 0.4). None of the patients discontinued use of EC-MPS and only mild adverse effects were seen. CONCLUSIONS: In this study EC-MPS at a dose of 720 mg twice daily for 6 months has proven to be an effective and well-tolerated treatment for patients with severe, recalcitrant AD.

Low bone mineral density in adult patients with moderate to severe atopic dermatitis.

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease commonly treated with topical corticosteroids. The inflammatory nature of this disorder and the use of topical corticosteroids represent potential risk factors for bone loss. OBJECTIVES: The aim was to assess the prevalence of osteoporosis and osteopenia in adult patients with moderate to severe AD. In addition, the associations between topical/oral corticosteroid use and bone mineral density (BMD) and between disease activity and BMD were studied. PATIENTS AND METHODS: We studied 125 adult patients with moderate to severe AD. Using dual-energy X-ray absorptiometry, BMD was measured at lumbar spine and hips. The cumulative dose of topical and oral corticosteroids was calculated from pharmacy prescription records. Lifestyle parameters were collected by a questionnaire. Biochemical parameters of bone metabolism and disease activity [serum concentration of thymus and activation-regulated chemokine (TARC) levels] were also measured. RESULTS: Osteoporosis was documented in six patients (4.8%) and osteopenia in 41 patients (32.8%); 30.4% of the patients had a Z-score

Low basal serum cortisol in patients with severe atopic dermatitis: potent topical corticosteroids wrongfully accused.

BACKGROUND: Topical corticosteroids are used extensively to treat inflammatory skin disorders including atopic dermatitis (AD). Several studies have described temporary reversible suppression of hypothalamic-pituitary-adrenal function. However, sound evidence of permanent disturbance of adrenal gland function is lacking. OBJECTIVES: To relate basal cortisol levels to prior use of topical corticosteroids and disease activity in patients with moderate to severe AD and to investigate the effect on basal serum cortisol levels of topical corticosteroid treatment during hospitalization. METHODS: Two groups of patients with AD were evaluated: 25 inpatients with severe AD who required hospitalization (group 1) and 28 outpatients with moderate to severe AD (group 2). In group 1, morning basal serum cortisol levels were measured twice, at admission and at discharge; in group 2, morning basal serum cortisol levels were measured once. Use of topical corticosteroids in the 3 months prior to the cortisol measurement was recorded and disease activity was monitored using the Six Area, Six Sign Atopic Dermatitis (SASSAD) score and serum thymus and activation-regulated chemokine (TARC) levels. RESULTS: On admission, basal cortisol levels in group 1 were significantly (P < 0.001) decreased in 80% of the patients. In group 2, the basal cortisol levels were normal in all but three patients. Comparing the two groups, group 1 on admission had a significantly lower cortisol level than that of group 2 (P < 0.001). Disease activity in group 1 on admission was significantly higher than that of group 2 (P < 0.001). There was no difference in use of topical corticosteroids in the 3 months before cortisol measurement. At discharge in group 1 there was a significant increase (P < 0.0001) of basal cortisol levels and a significant (P < 0.001) decrease in disease activity reflected by the decrease in serum TARC levels and SASSAD score. CONCLUSIONS: Disease activity, rather than the use of topical corticosteroids, is responsible for the low basal cortisol values in patients with severe AD.
