Acquired pneumonia

David P Serota, Mary Elizabeth Sexton, Colleen S Kraft, Federico Palacio
Acinetobacter baumannii is a rare but emerging cause of fulminant community-acquired pneumonia (CAP-AB). We describe a patient from a rural area who developed acute respiratory distress syndrome and septic shock. We describe risk factors and characteristics of this syndrome and review published cases of CAP-AB from North America.

Opportunistic infections (OIs) are the most significant complication of human immunodeficiency virus (HIV) infection. The prevalence of OIs differs among various countries in part due to different climates and socio-economic conditions. We, therefore, carried out the retrospective study at the Public Health Clinical Center of Chengdu, Sichuan to comprehensively investigate the prevalence of OIs, predictors of OIs, and risk factors for in-hospital death among HIV-infected patients. Sichuan in West China is characterized by the largest population living with HIV/Acquired immunodeficiency syndrome (AIDS) across China...

BACKGROUND: Withholding live-attenuated vaccines in patients using interleukin (IL)-1 or IL-6 blocking agents is recommended by guidelines for both pediatric and adult rheumatic diseases, since there is a risk of infection in an immune suppressed host. However, this has never been studied. This retrospective, multicenter survey aimed to evaluate the safety of live-attenuated vaccines in patients using IL-1 or IL-6 blockade. METHODS: We contacted physicians involved in the treatment of autoinflammatory diseases to investigate potential cases...

BACKGROUND: Disease severity scores such as CURB-65 are often used to guide the management of patients with community-acquired pneumonia. Early and adequate empirical antibiotic treatment reduces mortality. The aim of this study was to examine the severity assessment and management of patients presenting with community-acquired pneumonia at the European Gaza Hospital in the Gaza Strip and to compare this to the best available evidence. METHODS: Medical records of all patients admitted to the European Gaza Hospital with a diagnosis of community-acquired pneumonia between Dec 1, 2015, and March 31, 2016, were reviewed retrospectively...

We conducted a cohort study to identify characteristics associated with testing for, and testing positive for, coccidioidomycosis among patients with community-acquired pneumonia in southern California, USA. Limited and delayed testing probably leads to underdiagnosis among non-Hispanic black, Filipino, or Hispanic patients and among high-risk groups, including persons in whom antimicrobial drug therapy has failed.

Thrombotic microangiopathy (TMA) comprises a process of sequential endothelial damage, microvascular thrombosis, consumptive thrombocytopenia and microangiopathic haemolytic anaemia that can affect several organs, including the kidney. A 36-year-old woman was presented with a petechial rash 3 weeks after an upper respiratory tract infection. Laboratory results showed normocytic normochromic anaemia, thrombocytopenia and evidence of TMA with decreased haptoglobin, elevated serum lactate dehydrogenase and a peripheral blood smear with numerous schistocytes...

INTRODUCTION: Pneumonia is the leading cause of childhood morbidity and mortality globally. Introduction of the conjugate Haemophilus influenzae B and multivalent pneumococcal vaccines in developed countries including Australia has significantly reduced the overall burden of bacterial pneumonia. With the availability of molecular diagnostics, viruses are frequently detected in children with pneumonia either as primary pathogens or predispose to secondary bacterial infection. Many respiratory pathogens that are known to cause pneumonia are also identified in asymptomatic children, so the true contribution of these pathogens to childhood community-acquired pneumonia (CAP) remains unclear...

OBJECTIVES: Legionella pneumophila is the leading cause of Legionnaires' disease, a severe form of pneumonia acquired from environmental sources. Investigations of both sporadic cases and outbreaks mostly rely on analysis of a single to a few colony pick(s) isolated from each patient. However, due to the lack of data describing diversity within single patients, the optimal number of picks is unknown. Here, we investigated diversity within individual patients using sequence based typing (SBT) and whole genome sequencing (WGS)...

We report the case of a 47-year-old man with chronic obstructive pulmonary disease who was referred to our hospital for acute dyspnea. The radiologic findings revealed consolidation with a cavity in the left upper lobe of the lung. Blood/sputum cultures detected Pseudomonas aeruginosa. Despite intensive care, the patient died from respiratory failure. Autopsy revealed multiple small necrotizing cavities that had coalesced. Although P. aeruginosa is a known causative pathogen of community-acquired pneumonia in patients with structural lung disease, the radiologic findings were non-specific...

IMPORTANCE: The CURB-65 score is widely implemented as a prediction tool for identifying patients with community-acquired pneumonia (cap) at increased risk of 30-day mortality. However, since most ingredients of CURB-65 are used as general prediction tools, it is likely that other prediction tools, e.g. the British National Early Warning Score (NEWS), could be as good as CURB-65 at predicting the fate of CAP patients. OBJECTIVE: To determine whether NEWS is better than CURB-65 at predicting 30-day mortality of CAP patients...
