Anxiety and depression in adolescents with asthma and in their parents: A study in clinical practice

Emotional disorders, namely anxiety and depression, frequently affect adolescents with asthma. In addition, their parents also may present emotional problems. The objective of this study was to investigate anxiety and depression in asthmatic adolescents and in their parents in a real-life setting. A series of adolescents with allergic asthma were consecutively enrolled. Asthma was diagnosed according to the GINA document and consistently the symptom control grade was assessed. We used the HADS questionnaire for the adolescents, and HADS, STAY, and BDI questionnaires for their parents. Globally, 121 adolescents (71 males, 50 females, mean age 13.4±0.8 years, age ranging between 12 and 15 years) with allergic asthma and their parents were evaluated. Only 29% of adolescents had controlled asthma. Adolescents with controlled asthma had lower HADS-A and HADS-D scores than other patients, whereas there was no difference among parents. Severe maternal anxiety was more frequent in poorly controlled subjects than in partially controlled ones; absence of maternal anxiety was more common in controlled subjects. The preliminary results of the current study suggest that anxiety and depression are common in adolescents suffering from asthma as well as in their parents, mainly in mothers. Emotional disorders might affect also the asthma control. Thus, in clinical practice, the psychological assessment could be included in the asthma work-up

Storia naturale dell’infiammazione allergica

Allergic pathologies are the most common immunologic diseases and their prevalence and severity show a constantly increasing trend in industrialized countries. The present article presents some recent epidemiological data, the natural development of the allergic inflammation and its pathophysiology, focusing on the recent concept of a “minimal persistent inflammation”, with particular regard to its long term treatment with antiallergic drugs. In fact, according to the most recent interpretations, allergy has to be considered as a complex phenomenon, characterized by a inflammatory response to allergenic stimuli. The complicated interrelation between cells, cytokines and affected structures is described. Very often allergic diseases of the upper airways are associated with and complicate asthma, and data that support the benefits of treating these diseases as a whole are presented. Long-term treatment of allergies with antiflogistic/antiallergic molecules is capable of reducing tissutal damage, besides improving the quality of life of the patient and lowering the frequency of acute episodes. The chronic treatment with antiallergic drugs appears to be favorable also from a pharmacoeconomical point of view, as it is associated with a reduction of overall pharmaceutical expenses and of lost working/school days, as well as determining an improved quality of life for the patient and its relatives, particularly in pediatric age. The management of the allergic patient has always to be approached with an integrated multidisciplinary attitude, in which the efforts tend to the identification of all concurrent diseases, because the optimal treatment may be achieved only with the recognition and the resolution of all underlying diseases

Allergen-driven HLA-G expression and secretion in peripheral blood mononuclear cells from allergic rhinitis patients

It has been reported that soluble HLA-G serum levels are increased in patients with pollen-induced allergic rhinitis and decrease after immunotherapy. However, no functional study has been conducted so far. The aim of this study was to evaluate the membrane expression and secretion of HLA-G molecules in peripheral blood mononuclear cells from allergic rhinitis patients after in vitro incubation with the causal allergen

The Clinical Relevance of Gastroesophageal Reflux Disease and Laryngopharyngeal Reflux in Clinical Practice

Gastric reflux may be considered a para-physiological event that may occur up to 50 times a day. It usually happens when gas (less commonly liquids) flow back from stomach into esophagus. However, when defense mechanisms leave, disease may progress. If the esophagus is the trigger, gastroesophageal reflux disease (GERD) emerges. The prevalence of GERD in the primary care setting seems to be even more evident when one considers that, in the United States, 4.6 million office encounters annually are primarily for GERD, whereas 9.1 million encounters include GERD in the top 3 diagnoses for the encounter. GERD constitutes also the most frequently first-listed gastrointestinal diagnosis in ambulatory care visits. In addition, the extraesophageal manifestations of reflux, including LPR, asthma, and chronic cough, have been estimated to cost $5438 per patient in direct medical expenses in the first year after presentation and$13,700 for 5 years. Presently, the newest alginate compounds renowned the interest in this attracting and stimulating area. In this regard, a new medical device (Marial®), unique still now possessing the indication for both GERD and LPR, has been recently launched in the Italian market, two large surveys were conducted in Italy: RELIEF, involving 86 otolaryngologists, and EMERGE, involving 56 gastroenterologists. The aims of these surveys were: (1) to define clinical characteristics, including previous treatment, of the patients referred to consultation; (2) to evaluate the reliability of RFS, GIS, and RSI questionnaires in real-world settings, such as specialist office; and (3) to investigate the patients’ perception of efficacy of the prescribed therapy, based on the best practice and considering also the new medical device Comparing the patients’ perception of treatment efficacy, reduction in RSI values for each single symptom before and after a 4 week-treatment with Marial® alone or with PPI in add-on in EMERGE and RELIEF patients are reported. Marial® alone treatment induced a statistically significant higher reduction in each single symptom in RELIEF patients than in EMERGE patients, with the exception of heartburn, chest pain, indigestion, or stomach acid coming up. Similar results were obtained evaluating the reduction in RSI values in patients treated with PPI in add-on that was able to determine a higher statistically significant decrease in RELIEF than in EMERGE patients in each single symptom, with the exception of heartburn, chest pain, indigestion, or stomach acid coming up

Immunoglobulin Production Pattern in Allergic and Non-Allergic Subjects:

Allergic rhinitis (AR) is characterized by Th2 polarized immune response, such as increased IL-4 and reduced IFN-γ production, and by a functional defect of T regulatory cells. This impaired immune response profile influences the pattern of immunoglobulin (Ig) production in allergic patients. However, no studies have compared the pattern of inhalant allergen-specific Ig classes between allergic patients and normal subjects. The aim of this study is to therefore investigate the allergen-specific IgE, IgG, IgG4, and IgA serum level pattern in a group of patients with pollen allergy and in non-allergic healthy subjects. One hundred and two allergic patients (evaluated both out of and in the pollen season) were enrolled. In addition, 50 healthy non-allergic subjects were recruited during the whole year. Serum allergen-specific IgE, IgG, IgG4, and IgA for Parietaria, grasses, and birch were quantitatively determined by the ImmunoCAP System method. Allergen-specific IgE, IgG, IgG4, and IgA serum levels were significantly different for each tested allergen (p=0.0001 for each class) among groups. Allergic patients, mainly during pollen season, showed the highest IgG, IgG4, and IgA levels. The present study therefore provides the preliminary evidence that Ig production pattern toward inhalant allergens may depend on the specificity of the allergenic response both in non-allergic subjects and allergic patients Allergic patients do not show a defect of IgG and IgA classes. In addition, this study is the first that quantitatively evaluates the Ig classes. However, further studies should include non-allergic subjects evaluated both during and out of the pollen season

Immunoregulatory Role of HLA-G in Allergic Diseases

Allergic diseases are sustained by a T-helper 2 polarization leading to interleukin-4 secretion, IgE-dependent inflammation, and mast cell and eosinophil activation. HLA-G molecules, both in membrane-bound and in soluble forms, play a central role in modulation of immune responses. Elevated levels of soluble HLA-G (sHLA-G) molecules are detected in serum of patients with allergic rhinitis to seasonal and perennial allergens and correlate with allergen-specific IgE levels, clinical severity, drug consumption, and response to allergen-specific immunotherapy. sHLA-G molecules are also found in airway epithelium of patients with allergic asthma and high levels of sHLA-G molecules are detectable in plasma and bronchoalveolar lavage of asthmatic patients correlating with allergen-specific IgE levels. Finally, HLA-G molecules are expressed by T cells, monocytes-macrophages, and Langerhans cells infiltrating the dermis of atopic dermatitis patients. Collectively, although at present it is difficult to completely define the role of HLA-G molecules in allergic diseases, it may be suggested that they are expressed and secreted by immune cells during the allergic reaction in an attempt to suppress allergic inflammation
