Evaluation of house dust mite allergy in real life: patients' characteristics and satisfaction with treatment.

BACKGROUND: HDMs are a ubiquitous allergen source, with a very well defined biology, but their role in clinical settings and in everyday clinical practice is not well characterized. Aim of this cross-sectional, questionnaire-based study was to assess the clinical characteristics of HDM-related respiratory allergy in a large population of Italian patients. METHODS: A structured questionnaire was sent to allergists randomly chosen among those of the Italian Federation of Immunology, Allergy and Clinical Immunology (IFIACI). They were asked to fill it with the clinical data of 10-12 consecutive patients referred for respiratory allergy, positive to HDM skin prick test. The questionnaire assessed type and severity of allergy, demographics, yearly distribution of symptoms, treatment, and satisfaction with the therapy. RESULTS: 45 allergists collected data from 499 patients. Within the evaluated population, 42% had rhinitis only, 45% asthma + rhinitis and 13% asthma alone. Rhinitis was moderate/severe in 51% of patients. Asthma was intermittent in 36% of patients, mild in 37% and moderate in 27%. Conjunctivitis was the most frequent comorbidity (36%), followed by rhinosinusitis (16%), adenoid hypertrophy (6%) and polyposis (5%). Out of the population, 56.2% of patients were not at all or partially not satisfied of their treatment for rhinitis, whereas the percentage of dissatisfied patients was about 53% for asthma therapy. 34% patients (n = 170) were monosensitized to HDM. It is confirmed that patients have more symptoms during the fall-winter periods. CONCLUSION: Patients with HDM allergy have frequently moderate-severe rhinitis, and about 50% of them are not satisfied with their treatment.

Phase II trial of single-agent oral vinorelbine in elderly (> or =70 years) patients with advanced non-small-cell lung cancer and poor performance status.

BACKGROUND: Elderly patients with advanced non-small-cell lung cancer (NSCLC) with poor performance status (PS) are a special population requiring particular attention. Single-agent oral vinorelbine could be an attractive option. PATIENTS AND METHODS: A total of 43 patients with stage IIIB-IV NSCLC and Eastern Cooperative Oncology Group (ECOG) PS of two or more with good functional status were prospectively recruited. Oral vinorelbine was administered at the dose of 60 mg/m(2) on days 1-8 every 3 weeks. Primary end points were response rate and safety. RESULTS: Overall response rate was 18.6% with 8 partial responses; 18 of 43 (41.8%) experienced stable disease lasting >12 weeks and 17 of 43 (39.6%) disease progression for an overall clinical benefit of 60.4%. Median time to progression was 4.0 (range 2-22) months and median overall survival 8.0 (range 3-35) months. Treatment was well tolerated. Of 187 cycles, we did not observe any grade 3/4 toxicity with the exception of a single not-febrile G3 neutropenia. Regardless of severity, main toxic effects observed were nausea in 48.1% and vomiting in 22.9% of patients, anemia in 43.2%, fatigue in 32.6% and leukopenia in 23.2%. CONCLUSION: Single-agent oral vinorelbine is extremely safe in elderly patients with advanced NSCLC and ECOG PS of two or more and may represent a valid option in this very special population.

Characteristics of patients with allergic polysensitization: the POLISMAIL study.

BACKGROUND: The natural history of respiratory allergy is commonly characterized by a worsening of symptom severity, frequent comorbidity of rhinitis and asthma, and polysensitization to aeroallergens. The polysensitization phenomenon starts since childhood and is rare to find monosensitized adult patients. However, there are few studies investigating the characteristics of polysensitized patients. METHODS: This study was performed on a large cohort of patients with allergic rhinitis (assessed by ARIA criteria) and/or mild to moderate asthma (assessed by GINA). The kind and the number of sensitizations, their patterns, and the relation with quality of life (QoL) measured by the Juniper's RQLQ guestionnaire, were evaluated. RESULTS: Globally 418 patients (50.2% males, 49.8% females, mean age 26.4 years, range 3.5-65 years, 64 smokers, 371 non-smokers) were enrolled: 220 had allergic rhinitis alone, and 198 allergic rhinitis and asthma. The mean number ofsensitizations was 2.6. Three hundred-five patients (73%) had persistent rhinitis (PER), 220 of them with moderate-severe form. There was no significant derence in rate of rhinitis and asthma in monosensitized or polysensitized patients. Most patients were sensitized to pollens, whereas only 24.2% of them were sensitized to perennial allergens. Polysensitization was significantly associated with some issues of QoL, confirming previous findings, but not with number ofsensitizations. CONCLUSIONS: This study provides data confirming for poly-sensitized patients the relevance of ARIA classification of AR. PER is the most common form of AR in this cohort, symptoms are frequently moderate-severe, and asthma is present in about the half of patients with AR.
