Influence of body mass index, comorbidities and prior systemic therapies on the response of psoriasis to adalimumab: An exploratory analysis from the aphrodite data

Adalimumab is a fully human monoclonal antibody directed against tumor necrosis factor (TNF)-alpha, which is effective for the treatment of psoriasis and psoriatic arthritis (PsA). The aim of this study is to determine whether the response of psoriasis to adalimumab treatment might be influenced by certain particular factors, such as body mass index (BMI), history of biologic therapy, blood hypertension and metabolic comorbidities. For this reason, an exploratory analysis was conducted on 144 patients with psoriasis and concomitant PsA treated with adalimumab 40 mg every other week, evaluating the influence of such factors on the Psoriasis Area and Severity Index (PASI) response rate at week 12. Our preliminary results suggest that the response rate at week 12, in terms of both PASI-50 and PASI-75, appeared to be independent of the presence of hypertension and/or metabolic comorbidities. The PASI-50 response was observed more frequently in patients with BMI less than 30 as compared to obese patients (79% vs 58%, p = 0.02). Previous use of anti-TNF biologics did not appear to affect per se the rate of responders, although it was associated with a lower PASI-75 rate among responders. Copyright © by BIOLIFE, s.a.s

Distribution of congenital melanocytic naevi and congenital naevus-like naevi in a survey of 3406 Italian schoolchildren

Background: Scanty information is available on the prevalence of congenital melanocytic naevi (CMN) and congenital naevus-like naevi (CNLN), particularly the small ones. Objectives: To estimate the prevalence of CMN/CNLN in Italian schoolchildren, and to assess variations according to potential risk factors for melanoma. Methods: We conducted a survey in 13 Italian areas on 3406 schoolchildren aged 12-17 years. Children were examined by dermatologists who assessed pigmentary traits and made a count of small (6-15 mm in diameter) and medium/large (> 15 mm) CMN/CNLN on 19 anatomical areas. Results: Overall, 592 children (17.4%) had one or more CMN/CNLN. Prevalence of small CMN/CNLN was 16.1%, and that of medium/large CMN/CNLN was 1.8%. There was no difference between age groups and sexes. CMN/CNLN were more frequent in children with a higher number of common melanocytic naevi (multivariate odds ratio, OR = 7.1 for the highest vs. the lowest quartile), consistent in small (OR = 7.2) and medium/large CMN/CNLN (OR = 6.0). Family history of malignant melanoma (OR = 1.4) and personal history of diabetes (OR = 4.4) appeared to be directly, and sun exposure inversely associated with CMN/CNLN. No relation was evident between CMN/CNLN and pigmentary traits, anthropometric characteristics, dietary habits, freckles, sunburns, sunscreen use or history of selected diseases. Conclusions: The association with family history of melanoma, the strong association with acquired melanocytic naevi, and the lack of association with pigmentary traits and sunburns suggest that CMN/CNLN may act as an independent risk marker for subjects at increased risk for cutaneous melanoma later in life. © 2008 The Authors

Prevalence of atopic dermatitis in Italian schoolchildren: Factors affecting its variation

The frequency of atopic dermatitis in Italian children and its relationship with selected variables were analysed in a large survey of skin health conducted in Italy. In 1997 we conducted a survey on schoolchildren aged 12-17 years from 13 areas of northern, central and southern Italy. For the present analyses, 3179 Caucasian children (1618 males, 1561 females) were considered. A diagnosis of atopic dermatitis was reported in 224 cases (7.0%). The frequency of reported atopic dermatitis was significantly higher in children with asthma (rate ratio (RR) 4.5; 95% confidence interval (CI) 3.1-6.5). The lifetime prevalence of a diagnosis of atopic dermatitis was higher among schoolchildren reporting a diagnosis of psoriasis (RR 5.5, 95% CI 3.0-10.1) and vitiligo, (RR 16.1, 95% CI 6.5-39.5). This study gives estimates of the lifetime prevalence of atopic dermatitis in adolescents in Italy and emphasizes the direct association between the condition and other immune-related skin diseases. \ufffd\ufffd 2009 The Authors.

Improving sun protection behaviour in children: Study design and baseline results of a randomized trial in Italian elementary schools - The 'Sole Si Sole No GISED' project

Abstract: Objective: To evaluate, in the context of a randomized study, the 'Sole Si Sole No GISED' project, the effectiveness of an educational intervention to improve sun protection behaviour in schoolchildren. Methods: A large number of primary schools (classes II and III) in Italy were randomized to an educational intervention or control group: The intervention was conducted by trained teachers using ad hoc developed materials. Attitudes toward sun exposure and behaviour while in the sun were assessed at baseline and 1 year after concluding the educational intervention. In a subgroup of children, melanocytic naevi were counted on the upper limbs at the same intervals. The pilot phase of the study was started in 2001. Results: During the pilot phase, a total of 4,233 children was recruited. Of these, 2,116 were randomized to the active intervention and 2,117 to the control group. No difference for any of the study variables was documented between the 2 groups at baseline. About 20% of the children reported intense sun exposure during the year preceding the study. About 88% of the children reported adequate modalities of sun protection. Sunscreens were commonly used. A total of 508 children (12%) reported a history of sunburns in the year preceding the start of the study. Melanocytic naevi were counted in a total of 1,503 children (852 in the experimental and 651 in the control group). No differences in terms of skin, hair and eye colours were documented between the experimental and the control groups. The mean naevus count at baseline was 9.6 (median 7) in the experimental group and 10.1 (median 8) in the control group. Conclusion: About 50% of the total expected number of children was recruited during the pilot phase of the study. Randomization proved to be an excellent modality to select 2 samples similar for all the important study variables examined. A history of sunburns was reported less frequently than expected. The 'Sole Si Sole No GISED programme' is one of the few examples of a controlled evaluation of the effectiveness of an educational intervention in Ital

Nevus count on specific anatomic sites as a predictor of total body count: A survey of 3,406 children from Italy

Scanty information is available on the relation between nevus count on specific anatomic areas and the total body surface, particularly in children. The authors analyzed this issue by using data from a uniquely large study conducted in 1997 on 3,406 schoolchildren (1,746 boys and 1,660 girls) aged 13-14 years in 13 cities from northern, central, and southern Italy. Children were examined by trained dermatologists who counted melanocytic nevi (≥2 mm in diameter) on 19 different anatomic sites. Overall, the mean number of nevi was 17.3 (18.6 in boys and 15.8 in girls). The adjusted correlation coefficients (r) with number of nevi on the whole body were 0.74 for head and neck, 0.83 for anterior and 0.84 for posterior trunk, and 0.88 for upper and 0.80 for lower limbs. With reference to single anatomic sites, the best predictor of total nevus count was the lateral arms (r = 0.80), overall and in strata of sex and pigmentary characteristics. This large study provides definite evidence that examining the upper limbs only, particularly the lateral arms, is a practical and suitable tool for predicting total nevus count in children. © The Author 2007.

Improving sun-protection behavior among children: Results of a cluster-randomized trial in Italian elementary schools. The "SoleSi SoleNo-GISED" project

A history of sunburns in early life nearly doubles the risk of developing malignant melanoma in adulthood. From 2001 to 2004, we conducted a cluster-randomized trial of an educational intervention to reduce sunburn rates (primary outcome) and improve sun-protection behavior (secondary outcome) in schoolchildren. A total of 122 Italian primary schools (grades 2 and 3) were randomized to receive, or not, an intervention consisting of an educational curriculum at school, conducted by trained teachers, which included the projection of a short video and the distribution of booklets to children and their parents. Behavior while in the sun was assessed at baseline and 14-16 months after baseline. In a subgroup (44% of the total sample), melanocytic nevi were also counted. Of the 11,230 children enrolled, 8,611 completed the study. A total of 1,547 children (14%) reported a history of sunburns at baseline. At follow-up, no difference in sunburn episodes was documented between the study groups (odds ratio 0.97, 95% confidence interval 0.84-1.13) and similar sun-protection habits were reported. No significant impact of the proposed educational program was documented at 1-year follow-up. Innovative strategies need to be developed to increase the effectiveness of future educational interventions in this area. © 2007 The Society for Investigative Dermatology

Cutaneous reactions to analgesic-antipyretics and nonsteroidal anti-inflammatory drugs. Analysis of reports to the spontaneous reporting system of the Gruppo Italiano Studi Epidemiologici in Dermatologia

We analyzed the cutaneous reactions to systemic analgesic-antipyretics and non-steroidal anti-inflammatory drugs reported to the spontaneous reporting system of the Gruppo Italiano Studi Epidemiologici in Dermatologia (GISED). The system has been active since 1988, with periodic intensive surveillance exercises, and 202 dermatologists have collaborated. Up to December 1991, 2,137 reactions had been collected, of which 713 were reactions to systemic analgesic-antipyretics and nonsteroidal anti-inflammatory drugs. A general profile of the reactions was identifiable. It included, in order of frequency, urticaria/angioedema, fixed eruptions, exanthemas, erythema multiforme and Stevens Johnson syndrome. Fixed eruptions and Stevens Johnson syndrome were reported with exceedingly high frequency in association with feprazone. Our system also revealed previously unreported reactions, including fixed eruption to nimesulide, fixed eruption to piroxicam and fixed eruption to flurbiprofen
