RESUMEN
BACKGROUND: Therapeutic patient education (TPE) is recommended for children with atopic dermatitis (AD), but no consensus has been reached on the optimal tailoring of delivery. While repeated multidisciplinary group education sessions have shown effectiveness, the benefits of one-on-one educational interventions led by nurses for children with AD have not yet been assessed. OBJECTIVES: To assess the benefits of additional, well-structured, 1-h nurse-led individual TPE interventions in children with AD and their families compared with standard care alone. METHODS: Children with moderate-to-severe AD and their parents were randomized to receive a 1-h nurse-led education session in addition to standard care vs. standard care alone. The primary outcome was the area under the curve (AUC) of the SCORing of Atopic Dermatitis index (SCORAD) from baseline to week 24 (lower AUC values represent better long-term control of the disease). RESULTS: In our study, 176 patients were randomized across 11 centres, and 153 were included in the full analysis set. The mean (SD) age was 4.47 (4.57) years. By week 24, there were no significant differences in the AUCs of the SCORAD between the two groups (P = 0.3). Secondary outcomes including patient-reported severity and quality of life [AUCs of the patient-oriented SCORAD (PO-SCORAD) and Infants' Dermatitis Quality of Life Index (IDLQI), Children's Dermatitis Quality of Life Index (CDLQI) and Family Dermatitis Quality of Life Index (FDLQI)] were not significantly different between the two groups. The only significant change observed in the intervention group, when compared with the one receiving standard care, was a decrease in topical steroid phobia, as assessed by the topical corticosteroid phobia (TOPICOP) score. Prespecified subgroup analyses showed that disease severity in the intervention group was significantly lower throughout the study, compared with the standard-care group when participants had moderate AD at baseline (n = 47); while participants with severe AD at baseline (n = 106) did not show benefit from the intervention. Participants showed no additional benefit from the intervention regardless of age group. CONCLUSIONS: This study did not show any additional effectiveness, in long-term severity control, of a 1-h nurse-led TPE intervention in children with AD treated with standard care, compared with those treated with standard care alone. However, it should be noted that the intervention reduced the fear of using topical steroids and may be beneficial for patients in the subgroup with moderate AD.
Atopic dermatitis (AD), also known as atopic eczema, is a chronic relapsing disease that affects 715% of children worldwide. Therapeutic patient education (TPE) is recommended for children with AD, but no agreement has been reached on the best way to tailor delivery. While repeated multidisciplinary group education sessions in a hospital setting have been found effective, this type of intervention requires a lot of resources and is time-consuming. To assess the benefits of TPE in children with AD, researchers in France carried out this study with children with moderate-to-severe AD, to compare a 1-hour nurse-led education session in addition to standard care vs. standard care alone. The main aim of this research was to assess the effectiveness of a TPE intervention over a period of 6â months, using a measurement tool called the SCORAD (SCORing of Atopic Dermatitis index). We found no additional benefits in terms of long-term severity control and quality of life at 6â months of a 1-hour nurse-led education intervention in children with AD treated with standard care. However, it should be noted that the intervention reduced the fear of using topical steroids and may be beneficial for people in the moderate AD subgroup.

BACKGROUND: Limited and conflicting data have been reported on the impact of dupilumab (DUPI) on patch test (PT) results and its efficacy against allergic contact dermatitis (ACD). OBJECTIVE: This study was undertaken to analyze PT reactivities and relevance during treatment with DUPI to determine whether they could detect ACD in patients with uncontrolled or worsened atopic dermatitis (AD) who were receiving this agent. METHODS: This prospective, multicenter study examined 76 DUPI-treated patients who had undergone PTs. The relevant information was collected during 3 visits. RESULTS: Overall, 36 patients (47%) had ≥1 positive PT reaction, and 142 PT results were positive. Twenty-three patients (30%) had ≥1 positive and clinically relevant PT result. Five of them had clinical eczema improvement after allergen avoidance. We compared the PT results of 36 patients before and during DUPI therapy, representing 1230 paired PT allergens, of which 1022 were the same, 34 were positive, 44 were lost, and 130 were uninterpretable. LIMITATIONS: Because the number of patients included remains limited, our findings should be confirmed with a larger sample. CONCLUSION: Our results confirmed the usefulness of PTs for patients receiving DUPI, with good PT reproducibility. We suggest that all DUPI-treated patients with AD developing partial responses or experiencing symptom worsening should undergo PTs to look for contact sensitization.

The impact of chronic urticaria on work has been scarcely reported, whereas its peak incidence is between the ages of 20 and 40. The aim of this study was to assess the occupational impact of chronic urticaria and its treatment, by combining objective and patient-reported data. A monocentric observational study was performed using questionnaires over a 1-year period from 2021 to 2022 in chronic urticaria patients who were in a period of professional activity and agreed to participate. Of the 88 patients included, 55.7% assessed the occupational impact of their chronic urticaria as significant, and even more severe when chronic urticaria was poorly controlled. Some 86% of patients had symptoms at work, in a third of cases aggravated by work. However, occupational physical factors were not associated with an aggravation of inducible chronic urticaria. A total of 20% reported treatment-related adverse effects affecting their work. Despite low absenteeism, presenteeism and reduced productivity were important (> 20%). Six patients (6.8%) had difficulties keeping their work. For 72.7% of the patients, the occupational physician was not informed. The occupational impact of chronic urticaria should be discussed during consultations, particularly when it is insufficiently controlled. The occupational physician should be informed in order to support patients' professional project.

Patch testing is the only clinically applicable diagnostic method for Type IV allergy. The availability of Type IV patch test (PT) allergens in Europe, however, is currently scarce. This severely compromises adequate diagnostics of contact allergy, leading to serious consequences for the affected patients. Against this background, the European Society of Contact Dermatitis (ESCD) has created a task force (TF) (i) to explore the current availability of PT substances in different member states, (ii) to highlight some of the unique characteristics of Type IV vs. other allergens and (iii) to suggest ways forward to promote and ensure availability of high-quality patch testing substances for the diagnosis of Type IV allergies throughout Europe. The suggestions of the TF on how to improve the availability of PT allergens are supported by the ESCD, the European Academy of Allergy and Clinical Immunology, and the European Academy of Dermatology and Venereology and intend to provide potential means to resolve the present medical crisis.

RESUMEN
BACKGROUND: Human immunoglobulins are used for treating diverse inflammatory and autoimmune disorders. Eczema is an adverse event reported but poorly described. OBJECTIVES: To describe the clinical presentation, severity, outcome, and therapeutic management of immunoglobulin-associated eczema. METHODS: This retrospective and descriptive study included a query of the French national pharmacovigilance database, together with a national call for cases among dermatologists. RESULTS: We included 322 patients. Eczema occurred preferentially in men (78.9%) and in patients treated for neurological pathologies (76%). The clinical presentation consisted mainly of dyshidrosis (32.7%) and dry palmoplantar eczema (32.6%); 5% of cases exhibited erythroderma. Sixty-two percent of the eczema flares occurred after the first immunoglobulin course. Eczema was observed with 13 intravenous or subcutaneous immunoglobulin types and recurred in 84% of patients who maintained the same treatment and in 68% who switched the immunoglobulin type. After immunoglobulin discontinuation, 30% of patients still had persistent eczema. LIMITATIONS: Retrospective study, with possible missing data or memory bias. CONCLUSION: Immunoglobulin-associated eczema occurred with all immunoglobulin types, preferentially in patients with neurologic diseases who required prolonged immunoglobulin treatment. Recurrence was frequent, even after switching the immunoglobulin type, which can lead to a challenging therapeutic situation when immunoglobulin maintenance is required.

OBJECTIVE: To analyse the clinical characteristics and sensitivity of an essential oil patch test series (EOS) in patients sensitized to their own essential oils (EOs). METHOD: We analysed the clinical data and patch test results obtained with the European baseline series (BSE) and an EOS, as well as the mode of use of EOs, through a questionnaire included in the patient file. RESULTS: The study included 42 patients (79% women, average age 50 years) with allergic contact dermatitis (ACD), 8 patients required hospitalization. All patients were sensitized to the EO they used, primarily lavender (Lavandula augustifolia, 8000-28-0), tea tree (Melaleuca alternifolia leaf oil, 68647-73-4), ravintsara (Cinnamomum camphora oil, 92201-50-8), and 2 cases were attributed to helichrysum (helichrysum italicum flower absolute, 90045-56-0). 71% had positive patch tests to fragrance mix I or II, 9 only to the EOS and 4 only with their personal EO. Interestingly, 40% of patients did not spontaneously mention the use of EOs, and only 33% received advice on their use at the time of purchase. CONCLUSION: Patch tests with the BSE, limonene and linalool HP, and oxidized tea tree oil is sufficient to detect most EO-sensitized patients. The most important is to test the patient's own used EOs.

BACKGROUND: Allergic contact dermatitis to gloves is mostly induced by rubber accelerators. The European baseline series (EBS) appears insufficient to detect glove allergy. Since 2017, it is recommended to use the European rubber series (ERS) and to test the patients' own gloves. OBJECTIVES: To investigate the clinical profile of glove-wearing patients with hand eczema (HE) and to evaluate their sensitisation profile to glove allergens and the value of testing the patients' own gloves. METHODS: We conducted a French multicentre study of patients evaluated for HE between 2018 and 2020 and tested with the EBS, the ERS and their own gloves in patch tests and semi-open (SO) tests. RESULTS: A total of 279 patients were included; 32.6% of patients had positive tests to their own gloves or to glove allergens. Almost 45% of the sensitisations to glove allergens were detected only by the ERS. Among the patients tested both in patch tests and SO tests with their own gloves with positive results, 28% had positive SO tests only. Polyvinylchloride (PVC) gloves were positive in four patients. CONCLUSION: Our series confirms the need to test the ERS. All the patients' gloves must also be tested including PVC gloves. SO tests with gloves are useful as a complement to patch tests.

BACKGROUND: Allergic contact dermatitis (ACD) and photoallergic contact dermatitis (PACD) to benzophenone present in printing ink have been reported. However, precise chemical analyses and extended photo-patch tests have not been performed in these cases. OBJECTIVES: To determine which components present in a magazine cover are responsible for a patient's skin reaction, to determine the primary sensitizer, and precisely diagnose ACD and PACD. METHODS: After initial photo-patch tests were performed on a patient with a history of reaction to magazine covers after sun exposure, gas chromatography-mass spectrometry and high-performance liquid chromatography analyses of the magazine covers, and additional photo-patch tests were performed. RESULTS: The first photo-patch test results confirmed PACD to ketoprofen and fenofibrate and evoked PACD to the magazine covers. 4-methyl benzophenone (4-MBP) and 1-hydroxy-cyclohexyl-phenyl-ketone (1-HCPK) were found in the magazine cover. Additional photo-patch tests confirmed PACD to 1-HCPK and to benzophenone, and photo-aggravated ACD to 4-MBP. The primary sensitizer was ketoprofen. CONCLUSIONS: Benzophenones are present in a wide variety of products, without always being listed on the packaging. Patients previously sensitized to other ketones, such as ketoprofen, may react to benzophenones without being able to avoid contact with these molecules. New regulations may be needed for more efficient eviction advice.

BACKGROUND AND OBJECTIVES: The repeated open application test (ROAT) is an adjuvant investigation measure to patch testing in the diagnosis of allergic contact dermatitis. ESCD recommends a 15 days duration but its overall duration varies according to publications and patients hardly adhere to prolonged ROAT duration beyond 1 week. MATERIALS AND METHODS: The Dermatology and Allergy Group of the French Society of Dermatology performed a prospective study with the aim of determining the best duration for the ROAT. RESULTS: A total of 328 ROAT results were collected for topical products, including cosmetics (60%) and topical medications (31.1%). Fifty-nine (18%) ROATs were positive, and 16 (5%) were doubtful. All the positive ROATs occurred within 10 days, with a median time to positivity of 3 days. CONCLUSION: According to our results, a minimum duration of 10 days is necessary to achieve a positive ROAT to a topical product.

BACKGROUND: An aqueous antiseptic containing "chlorhexidine digluconate/benzalkonium chloride/benzyl alcohol" (CBB) is widely used in France. The only previous documented study dealing with allergic contact dermatitis (ACD) to this antiseptic is one small case series in children. The French Vigilance Network for Dermatology and Allergy (REVIDAL-GERDA) has collected many cases in the last few years. OBJECTIVES: To evaluate the clinical and sensitization profiles of patients diagnosed with ACD to CBB. METHODS: We performed a retrospective study of patients with contact dermatitis to CBB and positive tests to CBB and/or at least one of its components. All patients had to be tested with all components of CBB. RESULTS: A total of 102 patients (71 adults and 31 children) were included. The lesions were extensive in 63% of patients and 55% had delayed time to diagnosis. CBB patch tests were positive in 93.8% of cases. The allergen was identified in 97% of patients, mainly benzyl alcohol in adults (81.7%) and chlorhexidine digluconate in children (54.8%). About 32.4% of the patients were sensitized to several components. CONCLUSION: CBB is a cause of ACD at all ages. The components of the antiseptic should be tested. The sensitization profile seems to be different between adults and children.

BACKGROUND: Dupilumab is the first biologic available to treat atopic dermatitis (AD). Its effectiveness and safety were demonstrated in clinical trials. OBJECTIVE: We sought to assess the effectiveness and safety of dupilumab in adults with AD in a real-life French multicenter retrospective cohort. METHODS: We included patients treated during March 2017-April 2018. Efficacy outcomes, including Scoring Atopic Dermatitis (SCORAD) and Eczema Area and Severity Index (EASI) scores, were collected at baseline and 3 months when available. Adverse events (AEs) were recorded at follow-up. RESULTS: We included 241 patients. The median ± interquartile range (IQR) follow-up time was 3.8 ± 3.7 months. A ≥75% improvement in SCORAD was achieved in 27 of 163 (16.6%) patients, and a ≥75% improvement in EASI was achieved in 40 of 82 (48.8%) patients. The median SCORAD and EASI scores at 3 months were significantly lower than those at baseline (SCORAD ± IQR, 25 ± 21 vs 56 ± 27.4, P < 10-9 and EASI ± IQR, 4.1 ± 6.8 vs 17.9 ± 15.4, P < 10-9, respectively). Conjunctivitis was reported in 84 of 241 (38.2%) patients. The proportion with eosinophilia (>500 cells/mm3) during follow-up (57%) was higher than that at baseline (33.7%) (n = 172, P < 10-6). Dupilumab was stopped in 42 cases; 27 patients stopped because of AEs. LIMITATIONS: No control group, missing data. CONCLUSION: This real-life study demonstrated a similar dupilumab effectiveness as that seen in clinical trials, but it also revealed a higher frequency of conjunctivitis and eosinophilia.
