Systemic antibiotic use among children and adolescents in Germany: A population-based study
ABSTRACT The aim of the study was to comprehensively describe antibiotic use among children and young adolescents in Germany. Outpatient prescriptions of systemic antibiotics to children (<15 years) were analysed using data from four German statutory health insurances for the years 2004 to 2006. Annual prevalence of antibiotic prescriptions was determined using the average number of insured children during the respective year as reference population. Annual antibiotic prescription rates were calculated per 1,000 person years. Both figures were stratified by age (0-4, 5-9 and 10-14 years) and sex. Frequent indications for prescribing were analysed. Annual prevalence of antibiotic prescriptions rose from 35.68 % [95 % confidence intervals (CI), 35.62-35.75] in 2004 to 37.79 % [95 % CI, 37.72-37.86] in 2006. Prescription rates slightly increased by 6.01 % from 668.54 [95 % CI, 667.34-669.72] antibiotic prescriptions per 1,000 person years in 2004 to 708.71 [95 % CI, 707.47-709.95] in 2006. In 2006, prescriptions of broad-spectrum penicillins (25.09 %), second-generation cephalosporins (18.11 %) and narrow-spectrum penicillins (16.45 %) were most frequent. The most common indication for antibiotic prescribing was tonsillitis followed by bronchitis, otitis media, acute upper respiratory infections and scarlet fever. Conclusion: In contrast to other northern European countries, paediatric prescription rates are high in Germany. This and the frequent prescribing of broad spectrum agents for the treatment of mostly viral self-limiting conditions indicate limited adherence to evidence-based practice guidelines in antibiotic prescribing in the German outpatient setting.

- "Otitis media (OM) is one of the most common inflammatory diseases of children and therefore the third most common reason for antibiotic therapy in pediatrics (Holstiege et al., 2013). Although specific antibiotics are administered, the overall clinical effectiveness is limited due to low penetration of the drug to the middle ear mucosa (MEM) (Coates et al., 2008), inaccessibility of the bacteria within the grown biofilm (Post et al., 2004) as well as low symptomatic amendment within the first 24 h (Glasziou et al., 2004; Rovers et al., 2006). "
ABSTRACT: In the present study the glycosylation pattern of the middle ear mucosa (MEM) of guinea pigs, an approved model for middle ear research, was characterized with the purpose to identify bioadhesive ligands which might prolong the contact time of drug delivery systems with the middle ear mucosa (MEM). To assess the utility of five fluorescein labeled plant lectins with different carbohydrate specificities as bioadhesive ligands, viable MEM specimens were incubated at 4°C and the lectin binding capacities were calculated from the MEM-associated relative fluorescence intensities. Among all lectins under investigation, fluorescein-labeled wheat germ agglutinin (F-WGA) emerged as the highest bioadhesive lectin. In general, the accessibility of carbohydrate moieties of the MEM followed the order: sialic acid and N-acetyl-d-glucosamine (WGA)>mannose and galactosamine (Lensculinaris agglutinin)>N-acetyl-d-glucosamine (Solanumtuberosum agglutinin)>fucose (Ulexeuropaeus isoagglutinin I)>terminal mannose α-(1,3)-mannose (Galanthusnivalis agglutinin). Competitive inhibition studies with the corresponding carbohydrate revealed that F-WGA-binding was inhibited up to 90% confirming specificity of the F-WGA-MEM interaction. The cilia of the MEM were identified as F-WGA binding sites by fluorescence imaging as well as a z-stack of overlays of transmission, F-WGA- and nuclei-stained images of the MEM. Additionally, co-localisation experiments revealed that F-WGA bound to acidic mucopolysaccharides of the MEM. All in all, lectin-mediated bioadhesion to the MEM is proposed as a new concept for drug delivery to prolong the residence time of the drug in the tympanic cavity especially for successful therapy for difficult-to-treat diseases such as otitis media.

- "Our findings regarding paediatric cephalosporin use are in line with previous studies which reported strong variations of cephalosporin prescribing across Europe, with the lowest prescription rates in the Netherlands and Denmark [13,18-20,35]. Overall, the prescription rate of cefaclor (a second generation cephalosporin) in German children was the second highest after amoxicillin, and use of second generation cephalosporins was particularly common in very young children.

ABSTRACT: Background To describe the utilisation of antibiotics in children and adolescents across 5 European countries based on the same drug utilisation measures and age groups. Special attention was given to age-group-specific distributions of antibiotic subgroups, since comparison in this regard between countries is lacking so far. Methods Outpatient paediatric prescriptions of systemic antibiotics during the years 2005-2008 were analysed using health care databases from the UK, the Netherlands, Denmark, Italy and Germany. Annual antibiotic prescription rates per 1,000 person years were estimated for each database and stratified by age (≤4, 5-9, 10-14, 15-18 years). Age-group-specific distributions of antibiotic subgroups were calculated for 2008. Results With 957 prescriptions per 1000 person years, the highest annual prescription rate in the year 2008 was found in the Italian region Emilia Romagna followed by Germany (561), the UK (555), Denmark (481) and the Netherlands (294). Seasonal peaks during winter months were most pronounced in countries with high utilisation. Age-group-specific use varied substantially between countries with regard to total prescribing and distributions of antibiotic subgroups. However, prescription rates were highest among children in the age group ≤4 years in all countries, predominantly due to high use of broad spectrum penicillins. Conclusions Strong increases of antibiotic prescriptions in winter months in high utilising countries most likely result from frequent antibiotic treatment of mostly viral infections. This and strong variations of overall and age-group-specific distributions of antibiotic subgroups across countries, suggests that antibiotics are inappropriately used to a large extent.BMC Pediatrics 07/2014; 14(1):174.

ABSTRACT: Heavy antibiotic users are those individuals with the highest exposure to antibiotics. They play an important role as contributors to the increasing risk of antimicrobial resistance. We applied different methods to identify and characterise the group of heavy antibiotic users in Spain as well as their exposure to antibiotics. Data on outpatient prescribing of antimicrobials (ATC J01) in 2010 were obtained from a prescription database covering Aragón (northeastern Spain). The antimicrobial consumption at the individual level was analysed both according to the volume of DDD and the number of packages purchased per year. Heavy antibiotic users were identified according to Lorenz curves and characterised by age, gender and their antimicrobial prescription profile. Lorenz curves demonstrated substantial differences in the individual use of antimicrobials. Heavy antibiotic users (5% of individuals with highest consumption) were responsible for 21% of the total DDD consumed and received ≥6 packages per year. Elderly adults (≥60 years) and small children (0-9 years) were those exposed to the highest volume of antibiotics and with the most frequent exposure, respectively. Heavy users received a high proportion of antibiotics not recommended as first choice in primary health care. In conclusion, heavy antibiotic users consisted mainly of children and old adults. Inappropriate overuse of antibiotics (high quantity, high frequency and inappropriate antibiotic choice) lead to a substantial risk for the emergence and spread of resistant bacteria and interventions to reduce overuse of antibiotics should therefore primarily be targeted children and elderly people.
