RESUMEN
Background and Objective: Germany introduced routine varicella vaccination for all infants aged 11-14 months in 2004; since 2009, a second dose was recommended for toddlers aged 15-23 months. In Bavaria, vaccination with combined MMRV vaccine has been routinely reimbursed since the introduction of the 2-dose vaccination schedule. We investigated varicella vaccination coverage and factors associated with parental acceptance of varicella vaccination in the area of Munich from 2009 to 2011, within the frame of the 'Bavarian Varicella Surveillance Project' (2006-2011). Method: Annual cross-sectional parent survey of random samples of 600 children aged 18-36 months in Munich on the child's vaccination status for varicella and measles, socio-demographic data and parental attitude towards varicella vaccination. Results: During 2009-2011, the first dose varicella vaccination (VV) coverage increased from 53% (2009) to 68% (2011) while the second dose VV increased from 29% (2009) to 59% (2011). First-dose measles vaccination coverage was 88-91% (2009-2011). In 2009, 51% of all vaccinated children received the combined MMRV vaccine as first dose; in 2011, 94% (p<0.001). In 2009, 27% of all parents considered varicella vaccination as superfluous. This percentage had decreased to 15% by 2011. Recommendation of varicella vaccination by the physician was the most important explanatory factor and was significantly associated with parental acceptance of varicella vaccination in 2009 to 2011 (adjusted OR 11.5; 95%CI 3.6-36.3 (2009), 26.7; 95%CI 5.4-132.2 (2010) and 12.7; 95%CI 3.9-41.4 (2011)). Conclusions: From 2009 to 2011, first dose VV coverage further increased by approximately 15% up to 68%, corresponding with the increased use of MMRV. Although parental acceptance had increased, first dose coverage for varicella was still considerably lower than coverage for measles in 2011. Physician's recommendation of VV was the only independent factor significantly associated with parental acceptance in all study years. A further increase in varicella vaccination coverage is necessary in order to avoid potential negative effects such as an increase in the mean age of children getting infected with varicella. Therefore, information campaigns for both parents and physicians are urgently needed.

The prevalence of influenza A and B virus-specific IgG was determined in sera taken between 2008 and 2010 from 1,665 children aged 0-17 years and 400 blood donors in Germany. ELISA on the basis of whole virus antigens was applied. Nearly all children aged nine years and older had antibodies against influenza A. In contrast, 40% of children aged 0-4 years did not have any influenza A virus-specific IgG antibodies. Eightysix percent of 0-6 year-olds, 47% of 7-12 year-olds and 20% of 13-17 year-olds were serologically naïve to influenza B viruses. By the age of 18 years, influenza B seroprevalence reached approximately 90%. There were obvious regional differences in the seroprevalence of influenza B in Germany. In conclusion, seroprevalences of influenza A and influenza B increase gradually during childhood. The majority of children older than eight years have basal immunity to influenza A, while comparable immunity against influenza B is only acquired at the age of 18 years. Children aged 0-6 years, showing an overall seroprevalence of 67% for influenza A and of 14% for influenza B, are especially at risk for primary infections during influenza B seasons.

Since hepatitis A virus (HAV) infection during childhood is mostly asymptomatic, only seroprevalence studies can provide reliable information on incidence of HAV infection in children. The prevalence of anti-HAV antibodies was determined in sera taken in 2008 to 2010 from 1,645 children aged 0-17 years and in sera taken in 2010-2011 from 400 adult blood donors in Germany. For examination of trend over time, 715 sera collected between 1999 and 2006 from children at the age of 0-17 years within the federal state Thuringia were included. Antibody testing was carried out using the test kits ETI-AB-HAVK PLUS and ETI-HA-IGMK PLUS from DiaSorin. In children, the overall prevalence of antibodies was 10.8 %. After the seroprevalence declined from 8.8 % among the 0-2 year-olds to 2.4 % among the 3-4 year-olds, there was a significant increase to 20.5 % in the group of the 15-17 year-olds. Boys had with 12.7 % a significantly higher seroprevalence of anti-HAV antibodies compared to 8.8 % among girls. In adult blood donors, there was a HAV seroprevalence of 19.3 %. The likelihood of past infection or immunization within the age groups of children from 0 to 12 years differed significantly from that of adults. In conclusion, in Germany, only a small number of HAV infections occur in children, especially up to the age of 12 years. The proportion of susceptible children is greater than the proportion of susceptible adults. Thus, during outbreaks, the rate of infection among children would usually be higher than the rate among adults.

BACKGROUND: Rotavirus (RV) vaccination with the first generation vaccine (Rotashield) has been associated with intussusception (IS). Reliable age specific baseline incidence data for children ≤6 months of age in particular is fundamental for further post marketing monitoring of potential effects of recently introduced new RV vaccines. METHODS: IS incidence was estimated by a 2-source capture-recapture calculation (CRC) based on ESPED (German Paediatric Surveillance Unit) reports and on hospital discharge records for 2006 and 2007. ESPED as well as hospital records were validated according to the Brighton Collaboration's Group definition for definite IS. PATIENTS: Children that have been treated for IS in a hospital in one of two states of Germany (North-Rhine Westphalia and Bavaria). RESULTS: The annual IS incidence for infants <1 year in Germany calculated with the CRC estimate in Germany was 61.7/100 000 (95% CI: 54.5-70.1). However, the incidence appeared to vary by month of age over a range of 19.2/100 000 cases (95% CI: 12.5-30.4) in the first 3 months of life to 98.5/100 000 cases (95% CI: 80.9-120.6) during the 6 (th) to 8 (th) month. The male to female ratio for infants was 1.7:1 (95%CI: 1.6-1.8). CONCLUSION: The average incidence estimate for IS in infants (< 1 year) confirms previous estimates in Germany and Switzerland. However, age specific baseline incidence estimates for IS substantially vary during the first year of life. This has to be taken into account when analysing episodes of IS potentially associated with RV vaccination.

BACKGROUND: The clinical knowledge about the course, complications and treatment of COVID-19 in children and adolescents is so far limited. AIM: This systematic review summarizes the current scientific evidence regarding the clinical presentation of COVID-19 in hospitalized children based on available case series from China. In addition, first data from a nationwide pediatric hospital survey conducted by the German Society for Pediatric Infectious Diseases (DGPI) are presented. METHODS: This study evaluated 12 case series from China with 6-2143 children infected with SARS-CoV2, which were identified by a literature search in PubMed up to 31 March 2020. The database of the German nationwide DGPI COVID-19 survey was accessed on 6 April 2020. RESULTS: The median patient age in the case series was between 2 and 7 years and 18-45% were infants <1 year of age. The duration of hospital stay was 5-20 days. Most commonly reported symptoms were fever and cough; in 40-100% of cases involvement of the lower respiratory tract was reported, usually confirmed by computed tomography (CT). Severe and critical courses of disease were reported in up to 8% of the children including 2 fatalities. So far the German DGPI COVID-19 survey reported 33 hospitalized children up to 6 April 2020, mostly with upper airway infections. Of these children, 45% were infants and 32% had an underlying medical condition. So far 3 children (9%) needed admission to an intensive care unit. CONCLUSION: COVID-19 in hospitalized children usually presented as an uncomplicated febrile upper airway infection or mild pneumonia. Severe cases or fatalities rarely occurred in children. Information on neonates and children with underlying chronic conditions as well as on therapeutic and preventive measures are urgently needed.
RESUMEN
INTRODUCTION: Pediatric pneumococcal pneumonia complicated by parapneumonic pleural effusion/empyema (PPE/PE) remains a major concern despite general immunization with pneumococcal conjugate vaccines (PCVs). METHODS: In a nationwide pediatric hospital surveillance study in Germany we identified 584 children <18â¯years of age with bacteriologically confirmed PPE/PE from October 2010 to June 2018. Streptococcus pneumoniae was identified by culture and/or PCR of blood samples and/or pleural fluid and serotyped. RESULTS: S. pneumoniae was identified in 256 of 584 (43.8%) children by culture (nâ¯=â¯122) and/or PCR (nâ¯=â¯207). The following pneumococcal serotypes were detected in 114 children: serotype 3 (42.1%), 1 (25.4%), 7F (12.3%), 19A (7.9%), other PCV13 serotypes (4.4%) and non-PCV13 serotypes (7.9%). Between October 2010 and June 2014 serotype 1 (38.1%) and serotype 3 (25.4%) were most prevalent, whereas between July 2014 and June 2018 serotype 3 (62.7%) and non-PCV13 serotypes (15.7%) were dominant. Compared to children with other pneumococcal serotypes, children with serotype 3 associated PPE/PE were younger (median 3.2â¯years [IQR 2.1-4.3â¯years] vs. median 5.6â¯years [IQR 3.8-8.2â¯years]; pâ¯<â¯0.001) and more frequently admitted to intensive care (43 [89.6%] vs. 48 [73.8%]; pâ¯=â¯0.04). Seventy-six of 114 (66.7%) children with pneumococcal PPE/PE had been vaccinated with pneumococcal vaccines. Thirty-nine of 76 (51.3%) had received a vaccine covering the serotype detected. Thirty of these 39 breakthrough cases were age-appropriately vaccinated with PCV13 and considered vaccine failures, including 26 children with serotype 3, three children with serotype 19A and one child with serotype 1. CONCLUSION: Following the introduction of PCV13 in general childhood vaccination we observed a strong emergence of serotype 3 associated PPE/PE in the German pediatric population, including a considerable number of younger children with serotype 3 vaccine breakthrough cases and failures. Future PCVs should not only cover newly emerging serotypes, but also include a more effective component against serotype 3.

OBJECTIVES: Parapneumonic pleural effusions/empyema (PPE/PE) are severe complications of community-acquired pneumonia. We investigated the bacterial aetiology and incidence of paediatric PPE/PE in Germany after the introduction of universal pneumococcal conjugate vaccine (PCV) immunization for infants. METHODS: Children <18 years of age hospitalized with pneumonia-associated PPE/PE necessitating pleural drainage or persisting >7 days were reported to the German Surveillance Unit for Rare Diseases in Childhood between October 2010 and June 2017. All bacteria detected in blood or pleural fluid (by culture/PCR) were included, with serotyping for Streptococcus pneumoniae. RESULTS: The median age of all 1447 PPE/PE patients was 5 years (interquartile range 3-10). In 488 of the 1447 children with PPE/PE (34%), 541 bacteria (>40 species) were detected. Aerobic gram-positive cocci accounted for 469 of 541 bacteria detected (87%); these were most frequently Streptococcus pneumoniae (41%), Streptococcus pyogenes (19%) and Staphylococcus aureus (6%). Serotype 3 accounted for 45% of 78 serotyped S. pneumoniae strains. Annual PPE/PE incidence varied between 14 (95%CI 12-16) and 18 (95%CI 16-21) PPE/PE per million children. Incidence of S. pneumoniae PPE/PE decreased from 3.5 (95%CI 2.5-4.6) per million children in 2010/11 to 1.5 (95%CI 0.9-2.4) in 2013/14 (p 0.002), followed by a re-increase to 2.2 (95%CI 1.5-3.2) by 2016/17 (p 0.205). CONCLUSIONS: In the era of widespread PCV immunization, cases of paediatric PPE/PE were still caused mainly by S. pneumoniae and, increasingly, by S. pyogenes. The re-increase in the incidence of PPE/PE overall and in S. pneumoniae-associated PPE/PE indicates ongoing changes in the bacterial aetiology and requires further surveillance.

The aim of the present study was to compare the reduction of subjective complaints by 3 treatment strategies in 90 "amalgam patients" whose complaints could not be explained by a medical or psychological disorder. The individuals were randomly assigned either to removal of dental amalgam only (removal group), or removal in combination with a "biological detoxification" therapy with high doses of vitamins and trace elements (removal-plus group), or participation in a health promotion program without removal of dental amalgam (no-removal group). Between baseline and month 12, the sum score of main complaints decreased by 3.5 (SD=2.2) points on average in the removal group as well as in the removal-plus group, and by 2.5 (SD=2.4) points in the no-removal group (p=0.152). Both removal groups showed a significant decrease in steady-state levels of inorganic mercury compared with the no-removal group. Thus, all 3 interventions were associated with clinically relevant improvements.

OBJECTIVES: To investigate which patients receive acupuncture in the framework of statutory health insurance in Germany, how treatment was carried out, and what results were achieved. DESIGN: Basic documentation (carried out by physician) within a prospective observational study. SETTING: 454,920 patients with at least one of the three chronic pain conditions including headache, low back pain and osteoarthritis treated by 8727 medical acupuncturists (panel doctors) within the scope of a reimbursement program. RESULTS: Fifty-three percent of the patients were treated by general practitioners, 19% by orthopaedists and 9% by internists. Eighty percent of patients were female, mean age was 53.6 (S.D.=15.7) years. Primary indication for acupuncture was low back pain (45%), headache (36%), and osteoarthritis (12%). Median time since the initial diagnosis was 3 years. 8.4 (S.D.=3.0) acupuncture sessions (body acupuncture) were administered on average. In 28% a concomitant treatment was reported. Effectiveness of acupuncture was rated by physicians in 22% of the patients as marked, in 54% as moderate, in 16% as minimal and in 4% as poor (unchanged). In 8% of the patients mild adverse reactions were reported, severe side effects occurred in 13 patients (0.003%). Orthopaedists rated the effectiveness of acupuncture lower, showing shortest time for face-to-face contact with the patient. More acupuncture training did not correspond to better therapeutic effect assessed by physicians. CONCLUSIONS: Acupuncture proved a highly demanded treatment option for chronic pain conditions within the German research program. Results indicate that acupuncture provided by qualified therapists is safe, and patients benefited from the treatment.

OBJECTIVE: The aim of this paper is to describe the treatment and physician characteristics in a randomised trial of acupuncture for osteoarthritis of the knee. DESIGN: Three-armed, randomised, controlled multicentre trial with 1-year follow-up. SETTING: Twenty-eight outpatient centres in Germany. INTERVENTIONS: A total of 294 patients with osteoarthritis of the knee were randomised to 12 sessions of semi-standardised acupuncture (at least 6 local and 2 distant points needled per affected knee from a selection of predefined points, but individual choice of additional body or ear acupuncture points possible), 12 sessions of minimal acupuncture (superficial needling of at least 8 of 10 predefined, bilateral, distant non-acupuncture points) or a waiting list control (2 months no acupuncture). OUTCOME: Participating trial physicians and interventions. RESULTS: Forty-seven physicians specialised in acupuncture (mean age 43+/-8 years, 26 females) provided study interventions in 28 outpatient centres in Germany. The median duration of acupuncture training completed by participating physicians was 350 h (range 140-2508). The total number of needles used was 17.4+/-4.8 in the acupuncture group compared to 12.9+/-3.3 in the minimal acupuncture group. In total, 39 physicians (83%) stated that they would have treated patients in either a similar or in exactly the same way outside of the trial, whereas 7 (15%) stated that they would have treated patients differently (1 missing). CONCLUSIONS: Our documentation of the trial interventions shows that semi-standardised acupuncture strategy represents an acceptable compromise for efficacy studies. However, a substantial minority of participating trial physicians stated that they would have treated patients differently outside of the trial.

BACKGROUND: Acupuncture is widely used by patients with chronic pain although there is little evidence of its effectiveness. We investigated the efficacy of acupuncture compared with minimal acupuncture and with no acupuncture in patients with osteoarthritis of the knee. METHODS: Patients with chronic osteoarthritis of the knee (Kellgren grade < or =2) were randomly assigned to acupuncture (n=150), minimal acupuncture (superficial needling at non-acupuncture points; n=76), or a waiting list control (n=74). Specialised physicians, in 28 outpatient centres, administered acupuncture and minimal acupuncture in 12 sessions over 8 weeks. Patients completed standard questionnaires at baseline and after 8 weeks, 26 weeks, and 52 weeks. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index at the end of week 8 (adjusted for baseline score). All main analyses were by intention to treat. RESULTS: 294 patients were enrolled from March 6, 2002, to January 17, 2003; eight patients were lost to follow-up after randomisation, but were included in the final analysis. The mean baseline-adjusted WOMAC index at week 8 was 26.9 (SE 1.4) in the acupuncture group, 35.8 (1.9) in the minimal acupuncture group, and 49.6 (2.0) in the waiting list group (treatment difference acupuncture vs minimal acupuncture -8.8, [95% CI -13.5 to -4.2], p=0.0002; acupuncture vs waiting list -22.7 [-27.5 to -17.9], p<0.0001). After 52 weeks the difference between the acupuncture and minimal acupuncture groups was no longer significant (p=0.08). INTERPRETATION: After 8 weeks of treatment, pain and joint function are improved more with acupuncture than with minimal acupuncture or no acupuncture in patients with osteoarthritis of the knee. However, this benefit decreases over time.

BACKGROUND: We report on the study design and protocols of two randomized controlled trials (Acupuncture Randomized Trials = ART) that investigate the efficacy of acupuncture in the treatment of chronic low back pain and osteoarthritis of the knee, respectively. OBJECTIVE: To investigate whether acupuncture is more efficacious than (a) no treatment or (b) minimal acupuncture in the treatment of low back pain and osteoarthritis. DESIGN: Two randomized, controlled, multicenter trials with three treatment arms and a total follow-up time of 52 weeks. SETTING: 30 practitioners and outpatient units in Germany specialized in acupuncture treatment. PATIENTS: 300 patients will be included in each study. In the low back pain trial, patients will be included according to clinical diagnosis. In the osteoarthritis pain trial, patients will be included according to the American College of Rheumatology criteria. INTERVENTIONS: Patients are randomly assigned to receive either (1) semi-standardized acupuncture (150 patients), (2) minimal acupuncture at non-acupuncture points (75 patients), or (3) no treatment for two months followed by semi-standardized acupuncture (75 patients, waiting list control). Acupuncture treatment consists of 12 sessions per patient over a period of 8 weeks. MAIN OUTCOME MEASURE: The main outcome measure is the difference between baseline and the end of the 8-week treatment period in the following parameters: pain intensity as measured by a visual analogue scale (VAS; 0-100 mm) in the low back pain trial and by the Western Ontario and McMaster Universities Osteoarthritis Score (WOMAC) in the osteoarthritis trial. OUTLOOK: The results of these two studies (available in 2004) will provide health care providers and policy makers with the information needed to make scientifically sound assessments of acupuncture therapy.

BACKGROUND AND OBJECTIVE: We report the design and essentials of the protocols of two Acupuncture Randomized Trials (ART) investigating whether acupuncture is more efficacious than no treatment and minimal acupuncture in the interval treatment of migraine and tension-type headache. DESIGN: Randomized controlled multicenter trials with three treatment arms and a total observation period of 28 weeks. SETTING: 30 practitioners and outpatient units in Germany specialized in acupuncture treatment. PATIENTS: Per study 300 patients with migraine and episodic or chronic tension-type headache, respectively (diagnosis according to the criteria of the International Headache Society). INTERVENTIONS: Patients are randomly assigned to receive either (1) semi-standardized acupuncture (150 patients), (2) standardized minimal acupuncture (75 patients), or (3) no interval treatment for 12 weeks followed by semi-standardized acupuncture (75 patients, waiting list control). Acupuncture treatment consists of 12 sessions per patient over a period of 8 weeks. MAIN OUTCOME MEASURE: Main outcome measure in the migraine trial is the difference between the number of days with headache of moderate or severe intensity during the 4 weeks before randomization and weeks 9 to 12 after randomization. In the study on tension-type headache the main outcome measure is similar to that described above, but for the number of headache days regardless of intensity. OUTLOOK: The results of these two studies (available in 2004) will provide health care providers and policy makers with the information needed to make scientifically sound assessments of acupuncture therapy.

OBJECTIVE: To investigate characteristics and outcomes of patients undergoing acupuncture treatment for osteoarthritic pain under conditions of routine care in the framework of statutory health insurance in Germany. METHODS: Patients with chronic pain due to osteoarthritis (ICD-10 diagnoses M15 to M19) treated with acupuncture as the leading form of therapy were included in an observational study. Detailed questionnaires including instruments to measure pain intensity (numerical rating scales from 0 to 10), disability (Pain Disability Index) and quality of life (SF-36) were filled in before treatment, after treatment and at 6 months. Patients suffering from osteoarthritis of the knee and hip also filled in the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index questionnaire. RESULTS: A total of 736 patients were included in the main analysis. Seventy (10%) patients and 278 (38%) patients, respectively, suffered exclusively from primary osteoarthritis of the hip or knee, 239 (33%) from another type of osteoarthritis and 149 (20%) had more than one affected joint. On average, patients received 8.7 +/- 3.1 acupuncture treatments. Statistically significant and clinically relevant improvements were seen in all subgroups both after treatment and at 6 months in all major outcome measures. In patients with osteoarthritis of the hip, the WOMAC sum score was 47.9 +/- 20.7 at baseline, 34.8 +/- 20.0 after treatment and 33.1 +/- 22.2 at 6 months. The respective values in patients with osteoarthritis of the knee were 51.7 +/- 20.9, 34.1 +/- 23.3 and 34.6 +/- 25.1. CONCLUSIONS: In this study, patients with chronic pain due to osteoarthritis reported clinically relevant improvements after acupuncture treatment. Due to the uncontrolled design and the high proportion of patients lost to follow-up, the study findings must be interpreted cautiously.

These results are relevant to the choice of appropriate criteria for quality assessment of acupuncture and emphasize the role of patient satisfaction within quality assurance. Pre- and post-treatment differences in a set of pain related measurements were determined using a combination of data from an observational study and a survey of physicians. The following features of the physicians' study were investigated: specialisation, qualification in acupuncture, rate at which patients received acupuncture, use of further, complementary methods in the practice. The results were statistically adjusted according to different basic conditions (case-mix). A total of 4,084 patients with chronic headache, lower back pain or arthritic pain were treated by 1,838 acupuncturists. There were no differences in success for patients treated by physicians passing through shorter (A diploma) or longer (B diploma) training courses in acupuncture. Patients treated by orthopedists showed less improvement than those treated by physicians with other specialisations. However, these differences had disappeared 6 months after the onset of acupuncture.These longer term effects were more pronounced for physicians offering additional complementary methods in their practice. Improvement after acupuncture and patient satisfaction were positively correlated.

This paper describes the concept and realization of a nation-wide observational study which is part of the patient care evaluation programme on acupuncture as part of a model project of German statutory insurance bodies. The study aimed describing medical care with acupuncture to estimate the incidence of adverse reactions as well as the treatment effects of acupuncture in chronically ill patients with headache, low back pain or osteoarthritic pain. It was also intended to analyse relations between treatment effects and specialties of the treating acupuncturists. During the two-year period of report 9,918 acupuncturists took part in the study documenting 503,397 cases. A more comprehensive documentation is available for a sample of 10,366 patients with complete longitudinal data of 6,140 patients. The difficulties with data management and sampling technique are presented with reference to restricted capacities for monitoring. Furthermore the question of generalising of the results is discussed. There were differences in some respects (for example, frequencies of different indications) between the patient sample and the population of all patients included in the project. Patients also differed slightly with respect to the completeness of the longitudinal documentation. The results indicated that we cannot claim global representativeness for the sample-based findings, but there is no reason to assume a "positive" selection.
