Multidisciplinary Decision-Making-ITAlian Consensus After Two Years of Real Practice on the Management of Severe Uncontrolled CRSwNP by Biologics (ITACA Study).

PURPOSE OF REVIEW: We aimed to reach an Italian multidisciplinary consensus on some crucial aspects of treatment decision making in CRSwNP, following 2 years of clinical experience in order to support specialists in the management of CRSwNP in clinical practice. We addressed issues relating to therapeutic decision-making and shared criteria for the treatment choice, as well as appropriate timing and criteria for evaluating treatment response, and highlighted the need for repeated multidisciplinary assessments. RECENT FINDINGS: A national survey has been conducted recently to understand how rhinology practice has changed in Italy with the advent of biologics and how this affects patients with uncontrolled, severe CRSwNP. Despite the many published consensus documents, practical recommendations, and protocols on the use of biologics in CRSwNP, heterogenous behaviors in practice are still observed mainly conditioned by the novelty of the topic. The consensus procedure followed a modified Delphi approach. The scientific board included 18 otorhinolaryngologists and 8 allergists, who selected the 4 main topics to be addressed and developed overall 20 statements. Consensus on these statements was sought by a larger group of 48 additional experts, through two rounds of voting, the first web-based, the second in presence with discussion and possible refinement of the statements. The statements reaching an average score ≥ 7 at the second voting round were approved. Five statements were proposed for each of the following topics: baseline evaluation of patients eligible for biologic therapy; choice between different therapeutic options; assessment of the response to biologic treatment; multidisciplinary management. At the first voting round, 19 out of the 20 statements reached a mean score ≥ 7. Following the discussion and a few consequent amendments, at the second round of voting all the 20 statements were approved.

Effectiveness and Safety of Long-Term Dupilumab Treatment in Elderly Patients with Atopic Dermatitis: A Multicenter Real-Life Observational Study.

OBJECTIVE: The objective of this study was to assess the effectiveness and safety of dupilumab in treating elderly patients with atopic dermatitis from baseline to 52 weeks. METHODS: A retrospective observational real-life study was conducted in a group of elderly patients with severe atopic dermatitis treated with dupilumab for 52 weeks. Inclusion criteria were: age ≥ 65 years; diagnosis of atopic dermatitis made by an expert dermatologist; Eczema Area and Severity Index ≥ 24; and a contraindication, side effects, or failure to respond to cyclosporine. The primary outcome was the mean percentage reduction in the Eczema Area and Severity Index score from baseline to week 52. Secondary measures included the mean percentage reduction in the Pruritus and Sleep Numerical Rating Scales and the Dermatology Life Quality Index, and the types and rates of adverse events from baseline to week 52. RESULTS: One hundred and five patients were eligible for the study. Flexural dermatitis was the most frequent clinical phenotype (63.8%). The coexistence of more than one clinical phenotype was found in 70/105 (66.6%) patients. We observed a reduction in all disease severity scores from baseline to week 52 (p < 0.001). Adverse events were recorded in 30/105 (28.6%) patients, with conjunctivitis and injection-site reaction the most frequent. CONCLUSIONS: In this study, dupilumab is an effective and safe treatment for the long-term management of atopic dermatitis in patients aged over 65 years.

Hypersensitivity to Vitamins with a Focus on Immediate-Type Reactions: Food or Drug Allergy?

Vitamins are essential substances for normal cell functions, growth, and development. However, they cannot be produced by the human organism, so intake must be through the diet. Vitamin deficiency causes the onset of different diseases, ranging from pellagra to pernicious anemia, which can be corrected by reintroducing the missing vitamin form. To supply the right amount of vitamins to the body, every vitamin naturally occurring in foodstuff has been identified, extracted and synthetically produced, thus allowing either food fortification with these compounds or their pharmaceutical production. Furthermore, the increased importance attributed nowadays to body wellness and the pursuit of a permanent status of health at all costs has greatly encouraged a high consumption of vitamin supplements in modern society, since vitamin megadoses may be responsible for adverse or toxic effects. However, excessive vitamins can induce hypervitaminosis. In the USA, a national survey confirmed that 52% of adult Americans take at least one or more supplement products, vitamins and minerals being the most popular supplements in that country. Although vitamins are widespread natural substances, they may induce immediate or delayed type hypersensitivity reactions. Such adverse events are still underestimated and poorly recognized because only single cases have been reported in the literature, and no general review has yet investigated the mechanisms underlying sensitization to each vitamin, the diagnosis, and the management strategies adopted for vitamin hypersensitivity. Although delayed-type reactions to different vitamins are described in the literature, in our review, attention has been focused mainly on immediate- type reactions. Due to the importance of vitamins, further information regarding the above aspects (pathomechanisms, diagnosis and management) would be highly desirable to focus the state of the art on this particular, underestimated form of allergy, thus increasing allergists' awareness on these elusive hypersensitivity reactions.

Safety and treatment compliance of subcutaneous immunotherapy: A 30-year retrospective study.

BACKGROUND: Safety and treatment compliance are still considered important shortcomings of subcutaneous immunotherapy (SCIT). OBJECTIVE: To assess the rate of side effects (SE) to SCIT and treatment compliance at a hospital medically supervised facility. METHODS: A retrospective review of patients with allergic rhino-conjunctivitis (ARC) with or without asthma, who received SCIT to mites and pollens from 1988 to 2018, was performed. The information was collected from patient's allergen immunotherapy forms that had been prospectically filled in by expert physicians. RESULTS: Two thousand two hundred patients (50.2% males; mean age 29.4 ±â€¯11.7 years) received 3037 SCIT courses. A total of 91,187 injections were given, with a mean SCIT duration of 2.5 ±â€¯1.9 years. Nine hundred fifty-seven patients (43.5%) were compliant as they completed the minimally required treatment duration of 3 years. A total of 1087 SE (1.2% of all injections; 76.8% local reactions) were reported in 513 patients (23.3%). There were 42 anaphylactic reactions (in 29 patients) during the study period; two of these were severe. Adrenalin was administered only once. No anaphylactic shock was reported. Only 39 patients (1.8%) discontinued SCIT because of SE, the majority of whom (24; 61.5%) because of systemic reactions (urticaria, asthma, anaphylaxis). Parietaria vaccines were the most frequently associated to SE. Female gender, number of vaccines administered (2 vaccine vs. 1 vaccine) and year of SCIT inception (1996-2018 vs. 1988-1995) were independently associated to SE. CONCLUSION: SCIT, although not absolutely free of risk, is safe and well tolerated. There is still room for improvement of treatment compliance.
