From "blockbusters" to "biosimilars": An opportunity for patients, medical specialists and health care providers
Advances in basic research and research and development plans of pharmaceutical companies are radically changing the kind of available drugs and therapeutic targets. We are switching from predominantly chemical molecules, aimed at treating large populations of patients (blockbuster drugs), to a new generation of products, mostly biotech, aimed at modifying a specific pathogenetic mechanism. In other word we are moving fast to targeted therapy, which represents the first step toward personalized therapy, where the right drug at the right dose is administered to the right person, at the right time. Like the patent expiration of chemical products has corresponded to the development of generic drugs, the expiration of new biotech products will witness the appearance of biosimilars. The latter are biologic products that are highly similar but not identical to the reference medical products in terms of quality, safety and efficacy. This implies specific research, clinical monitoring, physicians updating of knowledge for a safe and appropriate use of these products. We are the beginning of a devolution in patient's care and physicians' practice. © 2012 Elsevier Ltd
360 degree perspective on allergic rhinitis management in Italy: A survey of GPs, pharmacists and patients
Background: General practitioners (GPs), community pharmacists and allergic rhinitis (AR) patients in Italy were surveyed in order to gain insight from all three perspectives into the diagnosis, management and burden of AR in Italy. Methods: General practitioners and pharmacists (n = 100 for each) were surveyed by telephone questions related to overall practice and to last AR patient seen. Patients (n = 552) completed a questionnaire after visiting specialist allergy centres. Questions related to diagnosis and treatment, degree of everyday limitation from AR, and satisfaction with treatment. The data were analysed descriptively. Results: Allergic rhinitis was managed mainly by GPs, who reported making the diagnosis themselves in 68 % of cases; rhinorrhea (64 %), sneezing (57 %) and congestion (49 %) were the symptoms most frequently taken into account. Limitation from AR on everyday life was rated 6.2 out of 10 by GPs. Pharmacists most often considered eye tearing (54 %) in their diagnosis. Almost half of GPs (49 %) and 87 % of pharmacists were unaware of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines. The most commonly reported prescribed treatments by GPs were branded mometasone furoate, desloratadine, ebastine and generic mometasone 21 % prescribed homeopathic products occasionally. On average, GPs remembered that their last patient case had moderate/severe disease, was prescribed anti-histamine monotherapy (37 % of cases), and did not change prescription (78 %). Pharmacists recommended an antihistamine for 56 % of clients who asked for advice, and a nasal decongestant for 21 %. Patients rated limitation from AR on everyday life as 5.7/10. 55 % reported using multiple therapies, and 43 % were not satisfied or weakly satisfied with their current treatment. Patients' main expectation for the future was to succeed in managing their AR symptoms (45 %), while 22 % hoped for a definitive cure. Many patients (61 %) were concerned their health would deteriorate. Conclusions: Allergic rhinitis is largely managed by GPs in Italy, with pharmacists also playing a role, yet awareness of the ARIA guidelines among these groups is low. Patient satisfaction with treatment is moderate or low. New more effective treatments are needed to improve AR management in Italy. Allergy education programs need to be better targeted to GPs and pharmacists, and communication with patients regarding symptom control must be improved
AIT (allergen immunotherapy): a model for the “precision medicine”
The interpretation of medical approaches, especially therapy, evolved rapidly in the last century. Starting from the simple description of symptoms, we moved to the pathophysiological descriptions, to the evidence-based medicine, until the so-called "precision medicine". This latter can be defined as a structural model aimed at customizing healthcare, with medical decisions/products tailored on an individual patient at a highly detailed level. In this sense, allergen immunotherapy represents an optimal model of "precision medicine", since we know and describe symptoms, function, aetiological agents at molecular level, and we have the possibility to intervene on the natural history of the disease. If considered under the point of view of pharmaco-economy, that is prescribing the optimal treatment to the right patient, allergen immunotherapy represents an almost-ideal model of precision medicine
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Clinically significant differences in patient-reported outcomes evaluations in chronic spontaneous urticaria
Purpose of review The aim of this review is to highlight the conceptual and practical knowledge for interpreting score changes in patient-reported outcomes (PROs) that have been validated for chronic spontaneous urticaria (CSU). Recent findings The urticaria guidelines recommends to assess PROs as Health-Related Quality of Life, disease activity and disease control, to detect the CSU impact and the overall treatment effect. To this aim it is crucial to determine the minimal important difference (MID) to assess if changes in questionnaire scores represent either perceived improvement or deterioration for patients. Methods for establishing the MID are well defined and are clustered into two broad categories: distribution-based and anchor-based. Summary For the majority of the available questionnaires for CSU, an MID has been defined, according to the results of various approaches. In most of the studies in our review, anchor-based methods, either alone or in combination with distribution ones, were used. The available information regarding MIDs across validated tools for CSU patients helps to interpret measurement scores and allows the implementation of PROs in routine practices
Type 2 immunity in asthma
Type 2-immunity represents the typical adaptive response to allergen exposure in atopic individuals. It mainly involves Th2 cells and immunoglobulin E, as the main orchestrators of type 2-inflammation. Recently, it has been highlighted that allergens may be responsible for a Th2 response beside specific IgE activation and that a number of other environmental stimuli, such as viruses and pollutants, can trigger the same pattern of inflammation beyond atopy. Emerging data sustain a substantial role of the so-called epithelial dysfunction in asthma pathogenesis, both from anatomic and functional point of view. Furthermore an increasing amount of evidence demonstrates the relevance of innate immunity in polarizing a Th2 impaired response in asthmatic patients. Under this perspective, the complex cross-talking between airway epithelium, innate and adaptive immunity is emerging as a major determinant of type 2-inflammation beyond allergens. This review will include an update on the relevance of dysregulation of innate and adaptive type 2-immunity in asthma pathogenesis, particularly severe asthma, and on the role of the allergens that are associated with severe asthma. Type 2-immunity also will be reviewed in the light of the current and upcoming targeted treatments for severe asthma
