Abstract Introduction Intra-seasonal start of treatment with the SQ® grass sublingual immunotherapy(SLIT) tablet (GRAZAX®, ALK, Denmark) has been previously demonstrated to be well-tolerated. The objective of our study was to investigate the tolerability of intra-seasonal start of treatment comparing patients treated by allergists and general practitioners experienced in treatment of allergy (GPs). Methods In a non-interventional, open-label, observational study, data on intra-seasonal start with the SQ® grass SLIT tablet were recorded in patients treated by allergists and GPs in Germany. Adverse events (AEs) were recorded by the physicians at first administration and during the 1–3-month observation period. The tablets taken and any AEs were recorded by the patients in diaries for the first 14 days. Results Treatment with the SQ® grass SLIT tablet was started in 198 patients, and in 179 intra-seasonal (allergists: 140, GPs: 39) and 19 post-seasonal; average treatment period was 47 days. AEs related to intra-seasonal start were reported in 43.6% of patients; no relevant differences between allergists and GPs were observed. In the subgroup of GPs, patients were younger (p = 0.0191), had more frequently asthma (p = 0.0043), more patients used symptomatic medication in the previous pollen season (p = 0.0198) and were more frequently treated for other diseases (p = 0.0467). In the allergists subgroup, more diagnostic allergy tests were applied (p

Background Oral allergy syndrome (OAS) triggered by fruit and vegetables often occurs in patients with pollen-induced rhinoconjunctivitis because of cross-reactive epitopes in pollen and associated foods. This open observational study examined the effect of pollen-specific sublingual immunotherapy ([SLIT] B. U. Pangramin or SLITone involving birch/alder/hazel, grasses/rye, and/or mugwort) on OAS triggered by several foods in patients treated in standard practice. Very few studies have examined SLIT use in this situation.Methods Patients (n = 102) had pollen-induced rhinoconjunctivitis and OAS and were followed for up to 12 months. Baseline OAS (triggers, symptoms, and symptom severity) was assessed by questionnaire and patient history. Change in OAS was assessed using oral challenge test with 1 or 2 dominant food triggers (and compared with the sum score calculated from the OAS questionnaire at baseline) and clinician ratings of change. Pollen-induced rhinoconjunctivitis symptoms and medication use were also measured.Results In the oral challenge test, 77.0% of patients were considered responders (decrease in sum score of ≥ 50%; no difference in patients receiving B. U. Pangramin or SLITone). At baseline, investigators rated OAS severity as at least moderate in 94.9% of patients compared with 36.9% after 12 months of treatment. After 12 months, OAS was rated as much or very much improved in 72.9% of patients. Sublingual immunotherapy significantly reduced rhinoconjunctivitis symptoms and medication use. Only 10% of patients experienced adverse drug reactions.Conclusion This study supplements the sparse literature on this topic and suggests that pollen-specific SLIT can reduce OAS triggered by pollen-associated foods in patients with pollen-induced rhinoconjunctivitis.

Background: The unique extract of a mixture of Baptisiae tinctoriae radix, Echinaceae pallidae/purpureae radix and Thujae occidentalis herba alleviates the typical symptoms of the common cold and shortens the duration of the disease. Purpose: The risk-benefit ratio of a concentrated formulation of this herbal extract was investigated under everyday conditions. Study design: Pharmacy-based, non-interventional, multicenter, open, uncontrolled study registered at DRKS00011068. Methods: For 10 days, patients completed a diary questionnaire rating the severity of each common cold symptom on a 10-point scale. For evaluation, symptoms were combined into the scores "overall severity", "rhinitis", "bronchitis" and "general symptoms". Cox models were used to evaluate the influence of covariates on the time of stable improvement. Results: In total 955 patients (12 to 90 years) were analyzed; 85% assessed the efficacy as good or very good. Response (improvement of the overall severity by at least 50%) was reached at median day 5 (95% CI median 5-5). General symptoms abated faster than the other complaints. The percentage of predominantly moderate or severe symptoms to predominantly mild or absent symptoms reversed on day 3.9 (interpolation). Results of adolescents and adults did not differ ( p =  .6013; HR = 0.918). Concomitant medication did not boost the effect of the herbal remedy. Early start of treatment of the cold accelerated the recovery ( p =  .0486; HR = 0.814). Thirty-four cases of adverse events were self-recorded in the diaries; none of them were serious. The tolerability was assessed as "good or very good" by 98% of the patients. Conclusion: The benefit-risk assessment of this herbal extract clearly remains positive. This non-interventional study accords with and shows transferability of the results of previous placebo-controlled studies with this extract in a real-life setting.

Objective: Studies suggest that parenteral MTX may be more efficacious than the oral form at equivalent doses for the treatment of rheumatoid arthritis. We carried out a meta-analysis to compare the efficacy of oral versus parenteral MTX in RA., Methods: PubMed, Web of Science and Embase were systematically searched from inception to June 8th 2017 and reviewed following PRISMA 2009 guidelines, by two independent reviewers. To be included, trials had to study adults with RA randomized to the same dose of either oral or parenteral MTX. The primary endpoint was ACR20 at 6 months. Intention-to-treat analysis results were used when possible. Data from direct comparisons between oral and parenteral methotrexate quantitatively analyzed using maximum likelihood random effects meta-analysis. Relative treatment effects were generated as an odds ratio [OR] (OR>1 indicated a benefit for parenteral therapy)., Results: The search yielded 357 papers or abstracts. After review of titles or abstracts and full text papers, we found 4 that met inclusion criteria with 703 patients randomized. Dose of MTX started at 15mg/week and increased up to 25mg/week. The summary OR for achieving ACR20 using parenteral vs. oral MTX was 3.02 (95% CI 1.41, 6.46), with no significant difference in the risk for all adverse events., Conclusion: Parenteral MTX therapy had significantly higher odds than oral MTX of achieving reduction in disease activity. We propose that parenteral MTX is more effective than weekly oral MTX; its widespread use may lead to better control of disease and a decrease in demand for biologic agents., Competing Interests: We have read the journal’s policy and the authors of the manuscript have the following competing interests: Dr. Jürgen’s original research was supported by funding from Medac GmbH.

Northern and mountainous ice sheets have expanded and contracted many times due to ice ages. Consequently, temperate species have been confined to refugia during the glacial periods wherefrom they have recolonized warming northern habitats between ice ages. In this study, we compare the gene CYP405A2 between different populations of the common burnet moth Zygaena filipendulae from across the Western Palearctic region to illuminate the colonization history of this species. These data show two major clusters of Z. filipendulae populations possibly reflecting two different refugial populations during the last ice age. The two types of Z. filipendulae only co-occur in Denmark, Sweden, and Scotland indicating that Northern Europe comprise the hybridization zone where individuals from two different refugia met after the last ice age. Bayesian phylogeographic and ecological clustering analyses show that one cluster probably derives from an Alpe Maritime refugium in Southern France with ancestral expansive tendencies to the British Isles in the west, touching Northern Europe up to Denmark and Sweden, and extending throughout Central Europe into the Balkans, the Peleponnes, and South East Europe. The second cluster encompasses East Anatolia as the source area, from where multiple independent dispersal events to Armenia, to the Alborz mountains in north-western Iran, and to the Zagros mountains in western Iran are suggested. Consequently, the classical theory of refugia for European temperate species in the Iberian, Italian, and Balkan peninsulas does not fit with the data from Z. filipendulae populations , which instead support more Northerly, mountainous refugia., Competing Interests: The authors have no conflict of interest to declare.

Background: For causal treatment by allergy immunotherapy (AIT) a single or few allergen products for the clinically most relevant allergens are applied to treat multiple allergies, but few data on the tolerability of multiple AIT applications are available., Objective: The aim of our study was to investigate safety and tolerability in patients treated by subcutaneous immunotherapy (SCIT) and concomitant SCIT or sublingual immunotherapy (SLIT) products., Methods: In a non-interventional, observational study in Germany treatment of patients with a primary SCIT and concomitant AIT (SCIT or SLIT) was documented during the first 4 months of treatment. Adverse events (AEs) were recorded by the physicians and by patients in diaries, and coded using the Medical Dictionary for Regulatory Activities (MedDRA)., Results: Three hundred and seven patients were treated with the primary SCIT by 79 allergists, and 271 received a concomitant AIT. AEs were reported in 92 (33.9%) patients and adverse drug reactions (ADRs) in 63 (23.2%) patients related to the primary SCIT and in 69 (25.5%) to the concomitant AIT; six (2.2%) patients discontinued due to ADRs. ADRs were mild or moderate in 40 (14.8%) patients, severe in 23 (8.5%), and serious in one patient. The most frequent reactions were local swelling and pruritus. Overall tolerability was assessed as 'good' or 'very good' by 95.6% of patients and 96.7% of physicians., Conclusions: Compared with data from a large previous study no increase in the frequency of ADRs in real life or change in the tolerability profile was observed for SCIT with concomitant SCIT or SLIT.

Background and Objective: Allergy immunotherapy (AIT) with the SQ(®) grass sublingual immunotherapy (SLIT)-tablet has been shown to be efficacious, well-tolerated and to improve disease-specific health-related quality of life (HRQoL) in controlled clinical trials. The aim of our study was to investigate HRQoL in patients with allergic rhinoconjunctivitis routinely treated with the SLIT-tablet and taking symptomatic medication as needed compared with patients treated only with symptomatic medication., Methods: In a non-interventional, open-label study, patients treated with the SLIT-tablet were observed for about 12 months compared with patients only symptomatically treated. Patients assessed their HRQoL with the 12-Item Short Form Health Survey (SF-12) and the Rhinitis Quality of Life Questionnaire (RQLQ) in the grass pollen seasons (GPS) at baseline (GPS1, HRQoL1), after GPS1 (HRQoL2) and in the following GPS (GPS2, HRQoL3). Tolerability, compliance, symptoms and medication use were assessed in the SLIT-tablet group by the physician., Results: Overall, data were analysed in 576 patients. Mean differences (±SD) in overall scores for HRQoL3 versus HRQoL1 (186 patients) of SF-12 were +11.4 ± 16.8 (SLIT-tablet) and -3.4 ± 15.7 (symptomatic medication), (p < 0.0001), and of RQLQ -1.31 ± 1.07 and +0.10 ± 0.74 (p < 0.001), and for HRQoL3 versus HRQoL2 (238 patients) of SF-12 -1.6 ± 15.3 and -10.0 ± 14.1 (p = 0.0003), and of RQLQ +0.22 ± 1.29 and +1.24 ± 1.30 (p < 0.0001). Tolerability and adherence for the SLIT-tablet were comparable with data of other non-interventional studies., Conclusions: Routine treatment with the SQ(®) grass SLIT-tablet resulted in clear improvements in disease-specific and general quality of life, while no improvements were observed in patients treated only symptomatically.

Background: The majority of allergic patients are poly-sensitized. For causal treatment by allergy immunotherapy (AIT) a single or few allergen products containing the clinically most relevant allergens are applied, but few data on tolerability of multiple application of AIT is available. The aim of our study was to investigate safety and tolerability in patients who started treatment by sublingual immunotherapy (SLIT) with the standardised SQ(®) grass SLIT-tablet and were treated with concomitant AIT products., Methods: In a non-interventional, open-label, observational study in Germany treatment of patients with the SQ(®) grass SLIT-tablet and concomitant AIT (SCIT or SLIT) was documented between January 2012 and January 2014. Patients were followed at visits at first administration of the SQ(®) grass SLIT-tablet and after 1-3 months of treatment. Tolerability of the treatment with the SQ(®) grass SLIT-tablet and concomitant AIT were assessed by the physician and administration of AIT and adverse events (AEs) were recorded by the patients in diaries. AEs and adverse drug reactions (ADRs) were coded by using the Medical Dictionary for Regulatory Activities., Results: In total, 181 patients were documented by 48 allergists and 160 patients treated with a concomitant AIT (SCIT 130, SLIT 30). AEs were reported in 58 (36.3 %) patients with concomitant AIT, and AEs considered related with the SQ(®) grass SLIT-tablet in 49 (30.6 %) and with concomitant AIT in 18 (11.3 %) patients. Treatment was discontinued due to ADRs in 12 (7.5 %) patients and severity of ADRs was assessed mild or moderate in 29 (18.1 %), and severe in 20 (12.5 %) patients. Most common reactions were localised at the application site of the SQ(®) grass SLIT-tablet as oral pruritus, throat irritation, oedema mouth and paraesthesia oral; no serious ADRs were reported. Overall tolerability of the SQ(®) grass SLIT-tablet if given with concomitant AIT was assessed as "good" or "very good" by 91.0 % of patients and 91.6 % of physicians., Conclusions: In comparison to data from previous studies no increase in frequency of AEs or change in the tolerability profile was observed when SLIT with the SQ(®) grass SLIT-tablet was administered with concomitant SCIT or SLIT.
