Carboplatin, a second-generation platinum compound, is a chemotherapeutic drug effective in many types of cancers. Its use is limited by the development of systemic allergic reactions in up to 30% of the cancer patients. Therefore, it is very important to make a correct diagnosis of true carboplatin allergy, for the crucial clinical implications. In this regard, no biological test is actually available to detect specific immunoglobulin E in the sera of patients allergic to carboplatin. We evaluated a new experimental biological test in patients with suspected immunoglobulin E-mediated reactions to carboplatin. Three patients with suspected hypersensitivity reactions to carboplatin underwent skin tests with an undiluted aliquot (10 mg/ml) of carboplatin preparation planned for infusion. Total serum immunoglobulin E and specific immunoglobulin E to the two platinum salts carboplatin and cisplatin were determined with the ImmunoCAP system (Phadia AB, Uppsala, Sweden). We detected specific immunoglobulin E to carboplatin in all three patients, whereas specific immunoglobulin E to cisplatin was observed in one patient. The positivity of specific immunoglobulin E against carboplatin in these three patients is a new and encouraging observation for the development of a new important instrument that can help clinicians in their therapeutic decisions, after a hypersensitivity reaction to a platinum salt.

Aim: Few studies have compared cluster immunotherapy and conventional administration regimens. The aim of this study was to establish the safety profile of these different regimens in patients with allergic respiratory diseases who received index-of-reactivity (IR)-standardized allergen extracts by the subcutaneous route. Materials & methods: The safety of subcutaneous immunotherapy (SCIT), administered by means of a 4-week cluster titration schedule (cluster-SCIT) or by an 8-week short conventional titration schedule (SC-SCIT), both with a target dose of 8 IR, was assessed in a retrospective, observational, multicenter study. Results: A total of 658 patients (339 cluster-SCIT and 319 SC-SCIT) were recruited from 92 sites in Spain. Injection site reactions occurred in 25.1 and 27.3% of patients treated with cluster-SCIT and SC-SCIT, respectively. Systemic reactions (European Academy of Allergy and Clinical Immunology criteria) were reported for 0.2% of doses and 1.5% of patients with cluster-SCIT, and 0.7% of doses and 4.4% of patients with SC-SCIT. Most reactions were mild and there were no grade 3 or 4 systemic reactions. No life-threatening systemic reactions, anaphylactic shock, or adverse events leading to therapy discontinuation were reported. Conclusion: The safety profile of the cluster regimen supports the use of accelerated SCIT schedules with IR-standardized allergen extracts compared with short conventional schedules, particularly if similar extracts and application methods are used. © 2013 Future Medicine Ltd.

Background: Little is known about the prevalence and clinical relevance of hypersensitivity to the plant panallergen profilin in children. Objectives: The present study aimed to investigate prevalence, risk factors and clinical relevance of profilin sensitization in a large cohort of Italian children of different ages living in different geographic areas. Methods: Children with pollen allergy enrolled by 16 pediatric outpatient clinics sited in three main geographic areas of Italy were studied. SPT were carried out with commercial pollen extracts and a commercial purified date palm pollen profilin. IgE specific for allergenic pollen molecules, Phl p 12 (grass profilin) and Pru p 3 (peach lipid transfer protein) were tested by ImmunoCAP FEIA. Results: IgE to Phl p 12 (0.35 kU/l) was observed in 296 of the 1,271 participants (23%), including 17 of the 108 (16%) preschool children. Profilin SPT was positive (3 mm) in 320/1,271 (25%) participants. The two diagnostic methods were concordant in 1,151 (91%, p < 0.0001) cases. Phl p 12 IgE prevalence declined from northern to southern Italy and was directly associated with IgE to Phl p 1 and/or Phl p 5 and Ole e 1. Among children with IgE to Phl p 12, OAS was provoked by kiwi, melon, watermelon, banana, apricot and cucumber. Conclusions: Profilin sensitization is very frequent among pollen-Allergic children, occurs at a very young age and contributes to the development of childhood OAS with a typical pattern of offending foods. Pediatricians should always consider IgE sensitization to profilin while examining pollen-Allergic children, even if they are at preschool age. © 2015 S. Karger AG, Basel.

Background: IgE-mediated sensitization to the Chenopodiaceae/Amaranthaceae families is a cause of allergic symptoms in arid areas. Salsola kali and Chenopodium album are considered the main species responsible; however, there is a discrepancy between the pollination period of these two plants and clinical symptoms. The objectives of this study were to identify new Chenopodiaceae/ Amaranthaceae members with sensitization capacity and to correlate symptoms, pollen counts and degree of flowering of different species. Methods: A total of 37 individuals monosensitized to S. kali and C. album were included in the study. All patients recorded daily symptom scores between May and October 2007. Extracts from Chenopodium (album, vulvaria and murale), Salsola (kali, vermiculata, and oppositifolia), Bassia scoparia, Atriplex (patula and halimus) and Amaranthus (deflexus and muricatus) were manufactured and used in skin prick tests (SPTs). Protein content and IgE binding were assessed for each extract. Pollen counts and degree of flowering (based on the Orshan specific semiquantitative method) were assessed weekly. Results: Symptom scores demonstrated a positive correlation with pollen counts even outside the pollination period of S. kali. Positive SPTs were obtained with all 11 species tested, which showed common proteins with IgE-binding capacity. Different species flowered at different times during the pollen season. Conclusion: Different taxonomically related species of Chenopodiaceae/Amaranthaceae can induce allergic sensitization and should be considered for use in diagnosis and treatment. Degree of flowering is a complementary method for assessing pollination that could be used for botanical families with indistinguishable pollen grains. Copyright © 2011 S. Karger AG, Basel.

Background: Burnout is a worrying problem in the medical profession and has proven to be highly prevalent in all the care settings and specialty areas in which it has been studied. We applied 2 widely used questionnaires to analyze the working conditions of Spanish allergists in terms of quality of professional life and degree of burnout perceived. Methods: Participants completed 2 questionnaires: the 22-item Maslach scale, a structured questionnaire covering different aspects of the feelings and attitudes of professionals toward their work and patients; and the Spanish Quality of Professional Life Questionnaire (CPV-35), a 35-item questionnaire evaluating job satisfaction and perceived quality of life at work. Results: We received 404 questionnaires from throughout Spain. The main sources of motivation were better pay (94.4%), more available resources/technology (85.1%), access to research activities (81%), and promotion in one's professional career (80.1%). Analysis of the scores from the Maslach scale revealed that two-thirds of the allergists interviewed experienced medium and high levels of negative burnout (67.9% and 66.2%, respectively, for emotional exhaustion and depersonalization). This situation was in part compensated for by the fact that a slightly lower proportion of the group (59.2%) obtained very high scores on personal accomplishment in their work. Analysis of the scores from the CPV-35 questionnaire revealed 3 complementary aspects of job satisfaction: perceptions of the workload borne (5.8), management support available to cope with daily patient workload (5.6), and levels of intrinsic motivation for work (7.7), which was the highest value. The score for the item summarizing self-perceived overall quality of working life was acceptable (6.4). Conclusion: Promoting intrinsic motivation of Spanish allergists using the motivating factors identifi ed in this study could protect against professional burnout. © 2011 Esmon Publicidad.
