Narrative review on the management of moderate-severe atopic dermatitis in pediatric age of the Italian Society of Pediatric Allergology and Immunology (SIAIP), of the Italian Society of Pediatric Dermatology (SIDerP) and of the Italian Society of Pediatrics (SIP).

Currently, there are a few detailed guidelines on the overall management of children and adolescents with moderate-severe atopic dermatitis. AD ​​is a complex disease presenting with different clinical phenotypes, which require an individualized and multidisciplinary approach. Therefore, appropriate interaction between primary care pediatricians, pediatric allergists, and pediatric dermatologists is crucial to finding the best management strategy. In this manuscript, members of the Italian Society of Pediatric Allergology and Immunology (SIAIP), the Italian Society of Pediatric Dermatology (SIDerP), and the Italian Society of Pediatrics (SIP) with expertise in the management of moderate-severe atopic dermatitis have reviewed the latest scientific evidence in the field. This narrative review aims to define a pathway to appropriately managing children and adolescents with moderate-severe atopic dermatitis.

Assessing patients' characteristics and treatment patterns among children with atopic dermatitis.

BACKGROUND: Atopic dermatitis (AD) is the most common immune-mediated skin disease in childhood. Several treatment options for pediatric AD, both topical and systemic, are currently available. We carried out a single-center observational study with the aim of describing characteristics and treatment patterns in pediatric AD patients. METHODS: The study included 867 patients aged ≤16 years (females 50.5%, mean patient's age 5.9 years, standard deviation ±3.6 years) with a previous doctor-confirmed diagnosis of AD who underwent balneotherapy at the Comano Thermal Spring Water Center (Comano, Trentino, Italy) from April to October 2014. RESULTS: Among the patients included in the study, 41.2% had mild (SCORing Atopic Dermatitis, SCORAD 0-15), 43.6% moderate (SCORAD 16-40) and 15.2% severe AD (SCORAD > 40). A higher occurrence of reported food allergy was observed among children with more severe AD (p < 0.0001), while no association was found between AD severity and reported inhalant allergy or passive smoking (p = 0.15 and 0.92, respectively). Emollients (55.1%) and topical corticosteroids (TCS; 45.7%) were the main treatment options used in the previous month. The use of oral steroids and topical calcineurin inhibitors (TCI) was considerably less common (6.3 and 4.5%, respectively), while no patients were on systemic agents other than steroids. Among patients with severe AD, 9.8% had not used TCS, TCI or any systemic treatments. Moreover, 20.0% of the patients in the study population had followed elimination diets, although only 27.2% of them had a reported food allergy. CONCLUSIONS: A significant difference in the prevalence of reported food allergy emerged across the different AD severity categories. Furthermore, although further data are necessary to confirm our findings, undertreatment in children with AD appeared to be very common, at least among those attending the Comano Thermal Spring Water Center. Moreover, many patients followed elimination diets in the absence of reported food allergy.

Characteristics associated with clinical response to Comano thermal spring water balneotherapy in pediatric patients with atopic dermatitis.

BACKGROUND: Several studies have investigated the efficacy of balneotherapy in atopic dermatitis (AD), including a pediatric open randomized clinical trial conducted at the Comano thermal spring water center, which showed a significant reduction in AD severity and an improvement of the quality of life. However, so far many studies on balneotherapy in pediatric AD have included relatively small populations without identifying patients' characteristics associated with their response. The aim of the present study was to identify any features associated with the clinical response to the Comano thermal spring water balneotherapy in a large cohort of pediatric AD patients. METHODS: An observational study was conducted on 867 children aged ≤16 years (females 50.5%, mean patient's age 5.9 years, standard deviation ±3.6 years) with mild to severe AD who underwent balneotherapy at the Comano thermal spring water center (Comano, Trentino, Italy) from April to October 2014. Patients were stratified according to their disease severity, which was evaluated using five SCORing Atopic Dermatitis (SCORAD) categories before and immediately after a thermal spring water balneotherapy course. Potential characteristics associated with the patients' clinical response to Comano thermal spring water balneotherapy were investigated. RESULTS: A statistically significant improvement in AD severity was observed after Comano thermal spring water balneotherapy (p < 0.0001). A significantly higher percentage of patients achieving improvement in AD severity was reported among children ≤4 years old (p < 0.0001) with early-onset AD (p < 0.0001), severe AD (p < 0.0001) or coexistent reported food allergies (p < 0.01). The therapy was well tolerated, and no relevant adverse effects were reported during the treatment course. CONCLUSIONS: Comano thermal spring water balneotherapy is a safe complementary treatment for pediatric patients with AD, as it was able to reduce the disease severity, especially in children ≤4 years old, with early onset AD, severe AD or concomitant food allergies.

Balneotherapy for atopic dermatitis in children at Comano spa in Trentino, Italy.

BACKGROUND: No controlled studies have investigated whether balneotherapy is effective in atopic dermatitis (AD). OBJECTIVES: To investigate the efficacy and safety of balneotherapy performed at Comano spa (Trentino, Italy) compared to topical corticosteroids (TCS) in the treatment of AD. METHODS: This was an open, randomized, clinical trial including 104 children (aged 1-14 years) with mild to moderate AD who were assigned either to balneotherapy (n = 54) or TCS (n = 50) once daily for 2 weeks. AD severity and quality of life were measured using the SCORAD, investigator global assessment (IGA), patients' self global assessment (PSGA), children's dermatology life quality index (CDLQI) and family dermatitis impact questionnaire (FDIQ). Subjective measures were re-evaluated 4 months after the end of therapy. RESULTS: Balneotherapy and TCS resulted in a significant reduction of all parameters at week 2. TCS were more effective than balneotherapy regarding SCORAD (46% ± 7.71 vs 26% ± 9.4, mean ± SD; p < 0.03). In contrast, IGA, PSGA, CDLQI and FDIQ improvement was similar. At month 4, the number and duration of relapses were less in patients treated with balneotherapy compared to those treated with TCS (p <0.0001). CONCLUSIONS: Balneotherapy at Comano spa appears to be beneficial in children with mild to moderate AD.

Risk of arrhythmias in myotonic dystrophy: trial design of the RAMYD study.

OBJECTIVE: Myotonic dystrophy type 1 (DM1) is the most frequent muscular dystrophy in adults. DM1 is a multisystem disorder also affecting the heart with an increased incidence of sudden death, which has been explained with the common impairment of the conduction system often requiring pacemaker implantation; however, the occurrence of sudden death despite pacemaker implantation and the observation of major ventricular arrhythmias generated the hypothesis that ventricular arrhythmias may play a causal role as well. The aim of the study was to assess the 2-year cumulative incidence and the value of noninvasive and invasive findings as predictive factors for sudden death, resuscitated cardiac arrest, ventricular fibrillation, sustained ventricular tachycardia and severe sinus dysfunction or high-degree atrioventricular block. METHODS/DESIGN: More than 500 DM1 patients will be evaluated at baseline with a clinical interview, 12-lead ECG, 24-h ECG and echocardiogram. Conventional and nonconventional indications to electrophysiological study, pacemaker, implantable cardioverter defibrillator or loop recorder implantation have been developed. In the case of an indication to electrophysiological study, pacemaker, implantable cardioverter defibrillator or loop recorder implant at baseline or at follow-up, the patient will be referred for the procedure. At the end of 2-year follow-up, all candidate prognostic factors will be tested for their association with the endpoints. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT00127582. CONCLUSION: The available evidence supports the hypothesis that both bradyarrhythmias and tachyarrhythmias may cause sudden death in DM1, but the course of cardiac disease in DM1 is still unclear. We expect that this large, prospective, multicenter study will provide evidence to improve diagnostic and therapeutic strategies in DM1.

Use of video capsule endoscopy in a patient with an implantable cardiac defibrillator.

Video capsule endoscopy (VCE) is a useful diagnostic tool in patients with unknown blood loss, particularly when there is a high suspicion of small bowel disease, but because of its use of radio frequency, it is relatively contraindicated in patients with a cardiac device. We report the case of a patient with an implantable cardiac defibrillator (ICD) who underwent VCE because of anaemia and previous surgery for colorectal cancer. Device interrogations were performed before and after the procedure. No interference between VCE and ICD was found. VCE is feasible and relatively safe in patients with ICDs.

Heart rate turbulence as a noninvasive risk predictor of ventricular tachyarrhythmias in myotonic dystrophy type 1.

INTRODUCTION: Myotonic dystrophy type 1 (MD1) is the most common muscular dystrophy of adult life. Cardiac involvement is characterized by disorders of atrioventricular conduction, ventricular arrhythmias, and sudden death. Heart rate turbulence (HRT) is a noninvasive risk predictor in patients affected by ischemic heart disease. The aim of our study is to assess the prognostic value of HRT in MD1 patients. METHODS AND RESULTS: We performed HRT analysis by 24-hour Holter recording to calculate turbulence onset (TO) and turbulence slope (TS) in 29 MD1 patients (mean age 52 +/- 10 years), and in 30 patients (mean age 52 +/- 13 years) with frequent ventricular arrhythmias and structurally normal heart (VANH). An electrophysiological study (EPS) tested ventricular arrhythmias inducibility in 22 MD1 patients. TO was significantly different between MD1 and VANH patients (-1.66 +/- 2.04 and -2.98 +/- 1.79%, respectively, P 0.01), while no difference was observed in TS between MD1 and VANH patients (11.12 +/- 6.46 and 9.12 +/- 6 msec/beat, respectively). On EPS, sustained ventricular arrhythmias (SVA) were induced in six MD1 patients. TO was significantly different in inducible MD1 patients (0.88 +/- 1.95%), as compared with both noninducible (-2.49 +/- 1.43%, P < 0.001) or no eligible to EPS (-1.93 +/- 1.63%, P < 0.005) MD1 patients and to VANH patients (-2.98 +/- 1.79%, P < 0.001). CONCLUSIONS: An impairment of TO, a measure of HRT, suggesting impaired cardiac parasympathetic activity, may be a useful, noninvasive predictor of arrhythmic risk in MD1 patients.

Widespread electroanatomic alterations of right cardiac chambers in patients with myotonic dystrophy type 1.

INTRODUCTION: Conduction disturbances and arrhythmias characterize the cardiac feature of myotonic dystrophy type 1 (MD1); a myocardial involvement has been suggested as part of the cardiac disease. The aim of our study was to investigate the underlying myocardial alterations using electroanatomic mapping (CARTO) and their possible correlation with genetic and neurological findings. METHODS AND RESULTS: Right atrial and ventricular CARTO maps were obtained in 13 MD1 patients. Thirteen age-matched patients with paroxysmal supraventricular tachycardia and normal heart served as controls. Unipolar voltage (UNI-v), bipolar voltage (BI-v) amplitudes, bipolar potential duration (Bi-dur), and atrial propagation time (A-pt) were measured. UNI-v and BI-v in interatrial septum, anterolateral atrial wall, and right ventricle outflow tract were lower in MD1 patients than controls (P < 0.001). Bi-dur and A-pt were longer in MD1 patients than controls (P < 0.001, P = 0.046, respectively). A significant relationship was documented between CTG triplets and the percentage of Bi-v <0.5 mV in the atrial anteroseptal region (r = 0.6, P = 0.02). CONCLUSIONS: Altered electroanatomic patterns are present in the right cardiac chambers in MD1 patients. Widespread myocardial alterations, not necessarily limited to the conduction system, may support the presence of a cardiac myopathy as part of the disease.
