Pneumonia can be classified as: community-acquired pneumonia (CAP), hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), healthcare-associated pneumonia (HCAP), and pneumonia in immunosuppressed patients. Although the above are similar pathologically, they are very different from a clinical perspective. Chest radiography is often performed to support the diagnosis and to determine the extent of involvement prior to the onset of therapy. Radiography should not be performed in the short term in patients who are improving clinically as it can lead to the misdiagnosis of treatment failure. Chest radiography in patients treated for pneumonia should only be obtained before 4-6 weeks after the onset of therapy if there is a failure of clinical response or if complications of pneumonia are clinically suspected. The majority of pneumonias will resolve after 6 weeks of appropriate antibiotic therapy.

Abstract BackgroundLegionella pneumophila is responsible for hospital or community-acquired pneumonia in adults. Immunocompromised patients with Legionella pneumophila infection are associated with rapidly severe clinical course and high mortality rates. Legionella pneumophila infection is rare in children, especially combined with extrapulmonary manifestations. In this report, we describe 2 children of severe hospital-acquired pneumonia and septic shock resulting from Legionella pneumophila. Standardized metagenomics next-generation sequencing allowed early diagnosis. Appropriate antibiotic therapy and timely extracorporeal life support were effective in achieving complete recovery. This is the first report of children with septic shock related to Legionella pneumophila infections diagnosed by metagenomics next-generation sequencing and recovered successfully.Case presentationThere were 2 cases about septic shock resulting from Legionella pneumophila. One was a six-month girl with congenital biliary atresia who underwent liver transplantation. She was suspected for rejecting the liver and admitted to hospital. The other one was a five-year-old boy with Burkitt lymphoma who was in the end of early chemotherapy. They both presented with fever, cough or shortness of breath during hospitalization. And they were transferred to PICU because of worsening dyspnea and decreased blood pressure. Patients were diagnosed by severe sepsis with septic shock likely resulting from hospital-acquired pneumonia. Metagenomics next-generation sequencing indicated L. pneumophila in blood and sputum. Aggressive intravenous fluids resuscitation and vasopressors were initiated on arrival to PICU, and they were placed on mechanical ventilation and continuous renal replacement therapy. Intravenous antibiotic therapy followed by azithromycin. Finally, the patients recovered without any long-term sequelae.ConclusionsThough sepsis or sepsis shock caused by Legionella pneumophila is rare in children, it can occur at high-risk population. Metagenomics next-generation sequencing is useful for conforming hard-to-culture pathogens and severely ill patients. The report remind pediatric physicians that we should be aware that Legionella pneumophila can cause severe sepsis or sepsis shock, especially in immunocompromised children. It is significant to select appropriate samples and pathogen detection methods in the early stage of disease.

Introduction: Inadequate empirical antibiotic therapy for HAP is a common phenomena and one of the indicators of the poor stewardship. This study intended to analyze the efficacy of empirical antibiotics in the light of microbiological data in HAP cases. Methods: Suspected cases of HAP were followed for clinico-bacterial evidence, antimicrobial resistance and pre and post culture antibiotic use. The study was taken from February,2014 to July, 2014 in department of Microbiology and department of Respiratory medicine prospectively. Data was analyzed by Microsoft Office Excel 2007. Results: Out of 758 cases investigated, 77(10 %) cases were HAP, 65(84%) of them were culture positive and 48(74 %) were late in onset. In early onset cases, isolates were Acinetobacter 10(42%), Escherichia coli 5(21%), S.aureus 4(17%), Klebsiella 1(4%) and Pseudomonas 1(4%). From the late onset cases Acinetobacter 15(28%), Klebsiella 17(32%) and Pseudomonas 13(24%) were isolated. All Acinetobacter, 78% Klebsiella and 36% Pseudomonas isolates were multi drug resistant. Empirical therapies were inadequate in 12(70%) of early onset cases and 44(92%) of late onset type. Cephalosporins were used in 7(41%) of early onset infections but found to be adequate only in 2(12%) cases. Polymyxins were avoided empirically but after cultures were used in 9(19%) cases. Conclusions: Empirical antibiotics were vastly inadequate, more frequently so in late onset infections. Use of cephalosporins empirically in early onset infections and avoiding empirical use of polymyxin antibiotics in late onset infections contributed largely to the findings. Inadequate empirical regimen is a real time feedback for a practitioner to update his knowledge on the local microbiological trends. Keywords: empirical therapy; hospital acquired pneumonia.
