Prevalence of self-reported drug hypersensitivity reactions among Lithuanian children and adults.

INTRODUCTION AND OBJECTIVES: Drug hypersensitivity reactions (DHRs) are the adverse effects of drugs that, when taken at doses generally tolerated by normal subjects, clinically resemble allergy. We aimed to assess the prevalence of self-reported DHRs among Lithuanian children and adults and to identify possible risk factors. MATERIALS AND METHODS: A cross-sectional survey of a population visiting their general practitioners in Vilnius and Kaunas regions of Lithuania was performed. Thirty-five questions on drug allergy symptoms, in addition, food, pollen allergy and family history were included. RESULTS: 3222 (60.0%) children and 2148 (40.0%) adults were included in the study. 7.9% of children and 13.8% of adults reported a DHR for at least one drug (p<0.001). 69.8% of children and 47.3% of adults, who indicated DHRs, had skin symptoms. Rate of anaphylaxis was similar in both groups (about 10%). 4.5% of children and 7.3% of adults had DHRs induced by antibiotics and this was the most implicated group of drugs. Significant self-reported risk factors for DHRs were family history of DHRs (OR=6.007, 95%CI 4.756-7.587), pollen allergy (OR=2.0, 95%CI 1.573-2.544), food allergy (OR=1.92, 95%CI 1.505-2.448), female gender (OR=1.439, 95%CI 1.187-1.744) and age (OR=1.017 in favour of adults, 95%CI 1.013-1.021). CONCLUSIONS: The prevalence of self-reported DHRs in Lithuania is higher among adults than children. Drug-induced skin reactions were the predominant symptom in both groups. Besides female gender and age, a positive family history of DHR and presence of pollen or food allergy may be associated with DHR.

Repeat treatment with icatibant for multiple hereditary angioedema attacks: FAST-2 open-label study.

BACKGROUND: The For Angioedema Subcutaneous Treatment (FAST)-2, a phase III, double-blind, randomized, multicenter, placebo-controlled study (ClinicalTrials.gov identifier: NCT00500656), established the efficacy and safety of single injections of icatibant, a bradykinin B2 receptor antagonist, in the treatment of hereditary angioedema (HAE) attacks. Here, we evaluate the efficacy and safety of repeated treatment with icatibant in adult patients experiencing HAE attacks during the FAST-2 open-label extension (OLE) phase. METHODS: Patients completing the controlled phase were eligible to participate in the OLE phase and receive open-label icatibant (30 mg subcutaneously) for the treatment of cutaneous, abdominal, and/or laryngeal HAE attack(s) severe enough to warrant treatment. Time to onset of symptom relief was calculated for each attack. Descriptive analyses (median, 95% CIs) were performed for all attacks; post hoc analyses were conducted in patients with at least five icatibant-treated attacks throughout the FAST-2 OLE phase. Safety was also monitored. RESULTS: Fifty-four patients received icatibant for 374 attacks (176 cutaneous, 168 abdominal, and 30 laryngeal). For cutaneous and/or abdominal attacks (attacks 2-5), the median times to onset of symptom relief ranged between 2.0 and 2.5 h. For all laryngeal attacks, the median times to regression (start of improvement) of symptoms ranged between 0.3 and 4.0 h. Post hoc analyses showed that the overall median time to onset of symptom relief was 2.0 h. Overall, 89.8% of attacks resolved with a single icatibant injection. No drug-related serious adverse events were reported. CONCLUSIONS: These findings have demonstrated the efficacy and safety of repeated icatibant treatment for HAE attacks.

Self-reported drug allergy in health care workers in conservative and surgical medicine departments.

BACKGROUND: Drug allergy comprises 10% to 30% of all adverse drug reactions, and according to data from the literature, sensitivity to drug allergens is 2 to 3 times more common in health care workers than in the general population. OBJECTIVE: The aims of this study were to estimate the prevalence of self-reported drug allergy in health care workers and compare the data obtained between doctors and nurses from conservative medicine (CM) and surgical medicine (SM) departments. METHODS: This was an analytic questionnaire-based survey conducted using the European Network of Drug Allergy questionnaire adapted to the Lithuanian population. The questionnaires were completed by 346 individuals. RESULTS: Nurses from SM departments reported allergy symptoms more frequently than doctors from the same departments (38.1% vs. 16.7%, P = .01) and nurses from the CM departments (38.1% vs. 18%; P = .02). The most common drugs reported to cause hypersensitivity symptoms were similar in the CM and SM departments: antibiotics (8.8% and 12.7%), local anesthetics (2.9% and 6.9%), and group B vitamins (1.2% and 2.1%). Skin damage was indicated as the most common clinical manifestation. CONCLUSIONS: Based on the data reported by the questionnaire respondents, drug allergy was most prevalent among nurses from the SM departments, and antibiotics and local anesthetics were the most common substances that induced the symptoms.

Primary immunodeficiencies in Central and Eastern Europe-the power of networking Report on the activity of the Jeffrey Modell Foundation Centers Network in Central and Eastern Europe.

Jeffrey Modell Foundation centers' network activities in Central and Eastern Europe (JMF CEE) have contributed to the development of care for patients with primary immunodeficiencies. On the data continuously collected from individual centers in participating countries since 2011, we demonstrate a steady improvement in a number of aspects concerning complex care for patients with primary immunodeficiencies. The presented data show an improvement of awareness about these rare diseases across the whole Central and Eastern European region, an increase in newly diagnosed patients as well as genetically confirmed cases, earlier establishment of diagnosis, and improved access to clinical treatment. We also present an active patient involvement that is reflected in the expansion of patient organization centers and their activities. The cooperation within the JMF CEE network has also contributed to greater international exposure of participating centers and further to the gradual development of research activities in the rapidly evolving field of primary immunodeficiencies. The improvement of all important aspects of the complex field of primary immunodeficiencies within the JMF CEE network documents the strength and advantages of the joint and coordinated networking.

Vilnius Declaration on chronic respiratory diseases: multisectoral care pathways embedding guided self-management, mHealth and air pollution in chronic respiratory diseases.

BACKGROUND: Over 1 billion people suffer from chronic respiratory diseases such as asthma, COPD, rhinitis and rhinosinusitis. They cause an enormous burden and are considered as major non-communicable diseases. Many patients are still uncontrolled and the cost of inaction is unacceptable. A meeting was held in Vilnius, Lithuania (March 23, 2018) under the patronage of the Ministry of Health and several scientific societies to propose multisectoral care pathways embedding guided self-management, mHealth and air pollution in selected chronic respiratory diseases (rhinitis, chronic rhinosinusitis, asthma and COPD). The meeting resulted in the Vilnius Declaration that was developed by the participants of the EU Summit on chronic respiratory diseases under the leadership of Euforea. CONCLUSION: The Vilnius Declaration represents an important step for the fight against air pollution in chronic respiratory diseases globally and has a clear strategic relevance with regard to the EU Health Strategy as it will bring added value to the existing public health knowledge.

Reversibility to a beta2-agonist in COPD: relationship to atopy and neutrophil activation.

Chronic obstructive pulmonary disease (COPD) is characterised by limited bronchial reversibility and chronic neutrophilic inflammation. However, in some cases of COPD, eosinophilic inflammation is present. We investigated the relationship between reversibility to beta2-agonist with atopy and neutrophil activation in patients with stable COPD. For this purpose, 38 outpatients with COPD (mean age: 64 years) 12 with asthma (mean age: 51 years) and 13 healthy controls (mean age: 49 years) were tested using increasing doses of inhaled salbutamol (up to 3100 microg). According to their reversibility, COPD patients were divided into two groups: reversible COPD (deltaFEV1 > or = 12% pred, n = 16) and non-reversible COPD (deltaFEV1 < 12% pred, n = 22). Atopy, assessed by skin prick, was found at similar frequencies in both COPD groups. Total serum IgE was higher in COPD patients vs. controls, but did not differ significantly between the COPD groups. The blood eosinophil count was significantly higher in the reversible COPD group than in the non-reversible COPD, and correlated with deltaFEV % pred (Rs = 0.54, P < 0.05), as well as in asthmatics. The non-reversible COPD group had a higher level of spontaneous neutrophil activation (by reduction of nitroblue tetrazolium) versus controls. We conclude that airway reversibility in COPD patients is associated with the degree of blood eosinophilia, but not with the degree of blood neutrophil activation.

Conclusions: The prevalence of self-reported DHRs in Lithuania is higher among adults than children. Drug-induced skin reactions were the predominant symptom in both groups. Besides female gender and age, a positive family history of DHR and presence of pollen or food allergy may be associated with DHR

Once daily fluticasone furoate nasal spray is effective in seasonal allergic rhinitis caused by grass pollen.

BACKGROUND: Fluticasone furoate is a new enhanced-affinity glucocorticoid with a unique combination of pharmacodynamic and physicochemical properties suitable for topical activity. METHODS: In this multicentre, randomized, double-blind, placebo-controlled, parallel-group study, patients [adults and adolescents >or=12 years of age with seasonal allergic rhinitis (SAR)] received once-daily (od) treatment for 2 weeks with either fluticasone furoate nasal spray 110 microg (n = 141) or placebo nasal spray (n = 144) administered in a unique, side-actuated device. Efficacy measures included total nasal symptom score (TNSS) and total ocular symptom score (TOSS). Patients also reported their overall response to therapy and rated their quality of life using the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). RESULTS: Fluticasone furoate significantly improved the mean change from baseline in daily reflective TNSS compared with placebo (treatment difference of -1.757; P < 0.001). Fluticasone furoate was also significantly more effective in improving the morning predose instantaneous TNSS (treatment difference of -1.898; P < 0.001) and daily reflective TOSS (treatment difference of -0.741; P = 0.001). A significant treatment effect was observed as early as day 1. Compared with placebo-treated patients, fluticasone furoate-treated patients showed significantly greater improvements in overall evaluation of response to therapy (P < 0.001), as well as in overall RQLQ score (P < 0.001). Fluticasone furoate was well tolerated. CONCLUSION: Fluticasone furoate nasal spray 110 mug od was effective in improving the nasal symptoms of SAR. It also produced significant improvements in ocular symptoms.

Effect of smoking cessation on cough reflex sensitivity.

Recent studies have shown that cigarette smokers have diminished cough reflex sensitivity compared with nonsmokers. The current authors proposed a mechanism of chronic cigarette smoke-induced desensitisation of airway cough receptors. To investigate this hypothesis, cough sensitivity to inhaled capsaicin (C5) in chronic smokers was measured both while they were actively smoking and 2, 6, 12 and 24 weeks after smoking cessation. In total, 29 subjects underwent baseline capsaicin challenge while smoking and 2 weeks after smoking cessation. Mean+/-sem log C5 fell from 1.86+/-0.12 to 1.60+/-0.12, demonstrating significant enhancement of cough reflex sensitivity. Of the total, 20, 18 and 14 subjects successfully abstained from smoking for 6, 12 and 24 weeks, respectively. Mean log C5 values after 12 and 24 weeks of smoking cessation were significantly diminished from baseline. In a control group of smokers, mean log C5 did not decrease from baseline after 6, 12 and 24 weeks. Overall, the log C5 profile of the smoking cessation group showed a clear, linearly decreasing trend over time compared with the control group. Even after many years of smoking, cough sensitivity is enhanced as early as 2 weeks after smoking cessation. Given the importance of an intact cough reflex, these changes may provide clinical benefit.
