Methodology/Principal Findings: Eight pediatric hospitals distributed over Germany prospectively provided sera from in-or outpatients aged 1 to 17 years from April 1(st) to July 31(st) 2010. Vaccination history, recall of infections and sociodemographic factors were ascertained. Antibody titers were measured with a sensitive and specific in-house hemagglutination inhibition test (HIT) and compared to age-matched sera collected during 6 months before the onset of the pandemic in Germany. We analyzed 1420 post-pandemic and 300 pre-pandemic sera. Among unvaccinated children aged 1-4 and 5-17 years the prevalence of HI titers (>= 1:10) was 27.1\% (95\% CI: 23.5-31.3) and 53.5\% (95\% CI: 50.9-56.2) compared to 1.7\% and 5.5\%, respectively, for pre-pandemic sera, accounting for a serologically determined incidence of influenza A (H1N1) 2009 during the season 2009/2010 of 25,4\% (95\% CI : 19.3-30.5) in children aged 1-4 years and 48.0\% (95\% CI: 42.6-52.0) in 5-17 year old children. Of children with HI titers >= 1: 10, 25.5\% (95\% CI: 22.5-28.8) reported no history of any infectious disease since June 2009. Among vaccinated children, 92\% (95\%-CI: 87.0-96.6) of the 5-17 year old but only 47.8\% (95\%-CI: 33.5-66.5) of the 1-4 year old children exhibited HI titers against influenza A virus (H1N1) 2009. Conclusion: Serologically determined incidence of influenza A (H1N1) 2009 infections in children indicates high infection rates with older children (5-17 years) infected twice as often as younger children. In about a quarter of the children with HI titers after the season 2009/2010 subclinical infections must be assumed. Low HI titers in young children after vaccination with the AS03(B)-adjuvanted split virion vaccine need further scrutiny.}, language = {en} } @article{WalitzaMelfsenJansetal.2011, author = {Walitza, Susanne and Melfsen, Siebke and Jans, Thomas and Zellmann, Henrike and Wewetzer, Christoph and Warnke, Andreas}, title = {Obsessive-Compulsive Disorder in Children and Adolescents}, series = {Deutsches {\"A}rzteblatt International}, volume = {108}, journal = {Deutsches {\"A}rzteblatt International}, number = {11}, doi = {10.3238/arztebl.2011.0173}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-141214}, pages = {173-I}, year = {2011}, abstract = {Background: Early-onset obsessive-compulsive disorder (OCD) is one of the more common mental illnesses of children and adolescents, with prevalence of 1\% to 3\%. Its manifestations often lead to severe impairment and to conflict in the family. In this review, we summarize the manifestations, comorbidity, pathophysiology, and course of this disease as well as current modes of diagnosis and treatment. Methods: We selectively review the relevant literature and the German-language guidelines for the diagnosis and treatment of mental illnesses in children and adolescents. Results: Obsessive-compulsive manifestations are of many types and cause severe impairment. Comorbid mental disturbances are present in as many as 70\% of patients. The disease takes a chronic course in more than 40\% of patients. Cognitive behavioral therapy is the treatment of first choice, followed by combination pharmacotherapy including selective serotonin reuptake inhibitors (SSRI) and then by SSRI alone. Conclusion: OCD often begins in childhood or adolescence. There are empirically based neurobiological and cognitive-behavioral models of its pathophysiology. Multiaxial diagnostic evaluation permits early diagnosis. Behavioral therapy and medications are highly effective treatments, but the disorder nonetheless takes a chronic course in a large percentage of patients.}, language = {en} } @article{KistlerSiwyFranketal.2011, author = {Kistler, Andreas D. and Siwy, Justyna and Frank, Breunig and Jeevaratnam, Praveen and Scherl, Alexander and Mullen, William and Warnock, David G. and Wanner, Christoph and Hughes, Derralynn A. and Mischak, Harald and W{\"u}thrich, Rudolf P. and Serra, Andreas L.}, title = {A Distinct Urinary Biomarker Pattern Characteristic of Female Fabry Patients That Mirrors Response to Enzyme Replacement Therapy}, series = {PLoS ONE}, volume = {6}, journal = {PLoS ONE}, number = {6}, doi = {10.1371/journal.pone.0020534}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-133526}, pages = {e20534}, year = {2011}, abstract = {Female patients affected by Fabry disease, an X-linked lysosomal storage disorder, exhibit a wide spectrum of symptoms, which renders diagnosis, and treatment decisions challenging. No diagnostic test, other than sequencing of the alpha-galactosidase A gene, is available and no biomarker has been proven useful to screen for the disease, predict disease course and monitor response to enzyme replacement therapy. Here, we used urine proteomic analysis based on capillary electrophoresis coupled to mass spectrometry and identified a biomarker profile in adult female Fabry patients. Urine samples were taken from 35 treatment-naive female Fabry patients and were compared to 89 age-matched healthy controls. We found a diagnostic biomarker pattern that exhibited 88.2\% sensitivity and 97.8\% specificity when tested in an independent validation cohort consisting of 17 treatment-naive Fabry patients and 45 controls. The model remained highly specific when applied to additional control patients with a variety of other renal, metabolic and cardiovascular diseases. Several of the 64 identified diagnostic biomarkers showed correlations with measures of disease severity. Notably, most biomarkers responded to enzyme replacement therapy, and 8 of 11 treated patients scored negative for Fabry disease in the diagnostic model. In conclusion, we defined a urinary biomarker model that seems to be of diagnostic use for Fabry disease in female patients and may be used to monitor response to enzyme replacement therapy.}, language = {en} }
