[Guidelines for the Management of Community Acquired Pneumonia in Children and Adolescents (Pediatric Community Acquired Pneumonia, pCAP) - Issued under the Responsibility of the German Society for Pediatric Infectious Diseases (DGPI) and the German Society for Pediatric Pulmonology (GPP)]

The present guideline aims to improve the evidence-based management of children and adolescents with pediatric community-acquired pneumonia (pCAP). Despite a prevalence of approx. 300 cases per 100 000 children per year in Central Europe, mortality is very low. Prevention includes infection control measures and comprehensive immunization. The diagnosis can and should be established clinically by history, physical examination and pulse oximetry, with fever and tachypnea as cardinal features. Additional signs or symptoms such as severely compromised general condition, poor feeding, dehydration, altered consciousness or seizures discriminate subjects with severe pCAP from those with non-severe pCAP. Within an age-dependent spectrum of infectious agents, bacterial etiology cannot be reliably differentiated from viral or mixed infections by currently available biomarkers. Most children and adolescents with non-severe pCAP and oxygen saturation 92 % can be managed as outpatients without laboratory/microbiology workup or imaging. Anti-infective agents are not generally indicated and can be safely withheld especially in children of young age, with wheeze or other indices suggesting a viral origin. For calculated antibiotic therapy, aminopenicillins are the preferred drug class with comparable efficacy of oral (amoxicillin) and intravenous administration (ampicillin). Follow-up evaluation after 48 - 72 hours is mandatory for the assessment of clinical course, treatment success and potential complications such as parapneumonic pleural effusion or empyema, which may necessitate alternative or add-on therapy.Die vorliegende Fassung der deutschsprachigen AWMF-Leitlinie soll unter Berücksichtigung der vorliegenden Evidenz die medizinische Versorgung von Kindern und Jugendlichen mit ambulant erworbener Pneumonie (pediatric community acquired pneumonia, pCAP) verbessern. In Mitteleuropa steht einer Prävalenz von ca. 300 Fällen pro 100 000 Kinder/Jahr eine sehr geringe Mortalität gegenüber, die Prävention umfasst Hygiene-Maßnahmen und Impfung z. B. gegen Pneumokokken, Hämophilus, Masern und Influenza. Hauptsymptome der pCAP sind Fieber und Tachypnoe, die Diagnosestellung erfolgt primär klinisch durch Anamnese, körperliche Untersuchung und Pulsoxymetrie. Das zusätzliche Vorliegen von Warnsymptomen wie stark reduzierter Allgemeinzustand, Nahrungsverweigerung, Dehydratation, Bewusstseinsstörung oder Krampfanfälle definiert die schwere pCAP in Abgrenzung zur nicht-schweren pCAP. Das Erregerspektrum ist altersabhängig, zur Differenzierung zwischen viraler, bakterieller oder gemischt viral-bakterieller Infektion stehen jedoch keine zuverlässigen Biomarker zur Verfügung. Die meisten Kinder und Jugendlichen mit nicht-schwerer pCAP und O
