RESUMEN
BACKGROUND: In order to evaluate the efficacy of intranasal mometasone furoate in patients with non-allergic rhinitis (NAR), a real-life, observational, prospective study is performed. METHODS: Thirty-one patients (age 18-64 years) receive intranasal (mometasone furoate, 200 µg b.i.d. for 15 consecutive days per month for 6 consecutive months), plus isotonic nasal saline. The cytologic pattern of local inflammation, nasal airflow, through peak nasal inspiratory flow (PNIF), quality of life (QoL), through the rhinitis quality of life questionnaire (RQLQ), the sinonasal outcome test (SNOT-22), the short-form 36-item health survey (SF-36v2), and the combined symptom medication score (CSMS), and, finally, olfactory function, through Sniffin' sticks-16 identification test (SSIT-16), are evaluated at baseline and after treatment. RESULTS: NARNE is the most frequent cytological pattern (48% of the total sample). The therapeutic response shows improvement in olfactory function and QoL. CONCLUSIONS: The results of this study confirm that intranasal mometasone furoate is an effective treatment for patients with NAR.
RESUMEN
Introduction: During COVID-19 pandemic, the massive use of Personal Protective Equipment could provoke severe adverse reactions in latex allergy patients and could negatively affect their quality of life. Methods: Trough a survey the study aimed: (a) to evaluate the incidence of allergic reactions in patients with latex allergy during the SARS-CoV-2 pandemic; (b) to evaluate the protective role of continuous latex sublingual immunotherapy (SLIT) during this period; and (c) to evaluate quality of life of natural rubber latex allergy (NRLA) patients during the pandemic. Results: 67 patients (9 males and 58 females, mean age of 45.9 ± 11.4 years) suffering from latex allergy were included in the present study. We recorded among our patients 13 cases (34.2%) of urticarial/angioedema (U/A), 9 cases (23.6%) of respiratory symptoms (dyspnoea, shortness of breath and wheezing) and 7 cases (18.4%) of anaphylaxis. In patients who underwent continuous SLIT, we observed less cases of U/A (p < 0.001), respiratory symptoms (p < 0.001), anaphylaxis (p = 0.003), hospitalizations (p = 0.014) and a lower therapy administration. We compared the results of SF-36 questionnaire in patients who underwent continuous and not-continuous SLIT with a significance differences score between these two groups. Conclusions: Our study is the first that investigated the clinical and quality of life effects of COVID-19 pandemic in NRLA patients.

Nickel (Ni) oral hyposensitization treatment (NiOHT) is an effective management approach for Ni allergy. No health-related quality of life (HRQoL) data exist for the pre- and post-treatment with NiOHT in systemic nickel allergy syndrome (SNAS). The aims of this study were (a) to explore HRQoL in SNAS patients, (b) to assess changes of HRQoL after 1 year of NiOHT; (c) to evaluate psychological status of patients. SNAS patients completed the Short-Form 36-Item Health Survey and Psychological General Well-Being Index before and 1 week after the end of NiOHT. Moreover, psychological state was assessed with the Minnesota Multiphasic Personality Inventory (MMPI-2). A total of 52 patients self-reported pre- and post-treatment questionnaires. HRQoL was poor at baseline. After 1 year of NiOHT, all outcome measure scores improved by about 20% with respect to baseline data (P < 0.01 for all indices, except depressed mood). Finally, 33 patients performed the MMPI-2. High rates for hypochondriasis and depression were noted. Furthermore, most of the patients had high scores for anxiety, depression, and health concerns. This is the first study showing that NiOHT improves HRQoL of SNAS patients, which can be considered a "personalized medicine" approach.

OBJECTIVE: The quantification of basophil activation by flow cytometry is a useful tool for the assessment of immediate-type responses to food allergens and the prediction of clinical tolerance in food allergy patients. The aim of this study is to investigate how the analysis of allergen-induced CD63 up-regulation by flow cytometry can be effective in monitoring the acquisition of clinical tolerance by specific oral desensitization in food allergy. To our knowledge, this is the first study to examine this topic. MATERIALS AND METHODS: Three male patients affected by cow's milk allergy underwent successful oral desensitization to cow's milk. In order to monitor the acquired clinical tolerance that occurred after treatment, we performed laboratory tests for total and specific IgE, specific IgG4 and the Basophil Activation Test (BAT) both at baseline and at the end of the desensitization protocol. RESULTS: Using a fluorescent enzyme immunoassay, the comparison of specific cow's milk antibodies before and after treatment showed a decrease of specific IgE levels, without reaching normal values, and an increase of specific IgG4 levels. A complete suppression of cow's milk proteins (α-lactoalbumin, ß-lactoglobulin and casein) induced CD63 regulation was observed in all three reported cases. CONCLUSIONS: Using flow cytometry, food allergen-specific basophil responses could be monitored in order to identify an acquired tolerance induced by desensitization treatment. Although further studies are needed to develop this important new topic, it was interesting to note that the BAT seemed to be more sensitive and characterized by a close correlation with clinical tolerance.
RESUMEN
OBJECTIVE: Allergic rhinitis (AR) is a disease with high and increasing prevalence. The management of AR includes allergen avoidance, anti-allergic drugs, and allergen specific immunotherapy (AIT), but only the latter works on the causes of allergy and, due to its mechanisms of action, modifies the natural history of the disease. Sublingual immunotherapy (SLIT) was proposed in the 1990s as an option to traditional, subcutaneous immunotherapy. MATERIAL AND METHODS: We reviewed all the available controlled trials on the efficacy and safety of SLIT. RESULTS AND CONCLUSION: Thus far, more than 60 trials, globally evaluated in 6 meta-analyses, showed that SLIT is an effective and safe treatment for AR. However, it must be noted that to expect clinical efficacy in the current practice SLIT has to be performed following the indications from controlled trials, that is, sufficiently high doses to be regularly administered for at least 3 consecutive years.

The house dust mite is a major cause of respiratory allergy worldwide. The management of mite allergy is based on avoidance measures, drug treatment, and allergen immunotherapy, but only allergen immunotherapy is able to modify the natural history of the disease. Injectable subcutaneous immunotherapy was introduced a century ago, while sublingual immunotherapy was proposed in the 1980s and emerged in the ensuing years as an effective and safe option to subcutaneous immunotherapy. However, the quality of the extracts to be used in allergen immunotherapy is crucial for the success of treatment. The mite extract for sublingual immunotherapy known as Staloral 300 was developed to offer optimal characteristics concerning the mite culture medium, standardization, and allergen dose. Double-blind, placebo-controlled trials with Staloral 300 have provided a substantial part of the clinical evidence analyzed in a meta-analysis of the efficacy of allergen immunotherapy in mite-induced rhinitis and asthma. Safety and tolerability are very good, mild local reactions in the mouth being the most common side effect. This makes it feasible to carry out sublingual immunotherapy for the 3-5-year duration needed to achieve long-lasting tolerance to the specific allergen. The performance of Staloral 300 may provide optimal conditions for an effective and safe sublingual immunotherapy in patients with mite-induced respiratory allergy.
