Komiya K, Yamatani I, Kadota JI. Treatment strategy for older patients with pneumonia independent of the risk of drug resistance in the world's top country for longevity. Respir Investig 2024; 62:710-716.

Abstract
The number of older people with impaired swallowing function increases with aging population. Aspiration pneumonia is one of the most cases of pneumonia developing among older people. As aspiration pneumonia may develop as a result of age-related deterioration, it is crucial to consider it as an unavoidable event with aging. While pneumonia is diagnosed based on respiratory symptoms and radiological features, the lung involvement of aspiration pneumonia may be undetectable via a frontal chest radiograph in some cases. Bacterial profiles show the predominance of drug-resistant bacteria, such as Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA), but isolated bacteria from respiratory samples do not necessarily indicate causative pathogens. Furthermore, there is no evidence regarding treatment superiority using broad-spectrum antibiotics compared with narrow-spectrum antibiotics. Even if isolated pathogens are a causative factor for pneumonia among older patients, the use of broad-spectrum antibiotics covering the bacteria may not improve their outcomes. Therefore, we propose a treatment strategy independent of the risk of drug resistance focusing on the discrimination of patients who are unlikely to respond to broad-spectrum antibiotics. An aspiration risk is associated with increased in-hospital mortality in patients with pneumonia, which could also lead to a greater risk of poor long-term outcomes with increased 1-year mortality. Advance care planning is now recognized as a process for communication and medical decision-making across the life course. This approach would be widely recommended for older people with aspiration risk.

Accuracy of the Infectious Diseases Society of America and British Thoracic Society Criteria for Acute Pneumonia in Differentiating Chemical and Bacterial Complications of Aspiration in Comatose Ventilated Patients Following Drug Poisoning. Antibiotics (Basel) 2024; 13:495. [PMID: 38927162 PMCID: PMC11200670 DOI: 10.3390/antibiotics13060495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 05/24/2024] [Accepted: 05/25/2024] [Indexed: 06/28/2024] Open
Abstract
Drug poisoning frequently leads to admission to intensive care units, often resulting in aspiration, a potentially life-threatening condition if not properly managed. Aspiration can manifest as either bacterial aspiration pneumonia (BAP) or aspiration pneumonitis (AP), which are challenging to distinguish potentially leading to overprescription of antibiotics and the emergence of multidrug-resistant bacteria. This study aims to assess the accuracy of the Infectious Diseases Society of America (IDSA) and British Thoracic Society (BTS) criteria in differentiating BAP from AP in comatose ventilated patients following drug poisoning. This cross-sectional study included 95 patients admitted for drug poisoning at the Lille University Hospital intensive care department, between 2013 and 2017, requiring mechanical ventilation and receiving antibiotics for aspiration. Patients were categorized as having bacterial complications if tracheal sampling yielded positive culture results, and if they were otherwise considered to have chemical complications. The sensitivity, specificity, positive predictive value, and negative predictive value of IDSA and BTS criteria in identifying patients with bacterial complications were evaluated. Among the patients, 34 (36%) experienced BAP. The IDSA criteria demonstrated a sensitivity of 62% and specificity of 33%, while the BTS criteria showed a sensitivity of 50% and specificity of 38%. Both the IDSA and BTS criteria exhibited poor sensitivity and specificity in identifying microbiologically confirmed pneumonia in comatose ventilated patients following drug poisoning.

Abstract
Aspiration pneumonia is a lower respiratory tract infection that results from inhalation of foreign material, often gastric and oropharyngeal contents. It is important to distinguish this from a similar entity, aspiration with chemical pneumonitis, as treatment approaches may differ. An evolving understanding of the human microbiome has shed light on the pathogenesis of aspiration pneumonia, suggesting that dysbiosis, repetitive injury, and inflammatory responses play a role in its development. Risk factors for aspiration events involve a complex interplay of anatomical and physiological dysfunctions in the nervous, gastrointestinal, and pulmonary systems. Current treatment strategies have shifted away from anaerobic organisms as leading pathogens. Prevention of aspiration pneumonia primarily involves addressing oropharyngeal dysphagia, a significant risk factor for aspiration pneumonia, particularly among elderly individuals and those with cognitive and neurodegenerative disorders.

Abstract
BACKGROUNDS It remains unclear if antibiotics should be used for the treatment of acute aspiration bronchitis to prevent the development of pneumonia. This study aimed to assess the associations between the use of antibiotics and the development of pneumonia among patients with acute aspiration bronchitis. METHODS We retrospectively reviewed consecutive patients with acute aspiration bronchitis aged ≥75 years. Acute aspiration bronchitis was defined as a condition with aspiration risk, high fever (body temperature, ≥37.5 °C), respiratory symptoms, and the absence of evidence of pneumonia. RESULTS There was no significant difference in the incidence of pneumonia between patients treated with and without antibiotics for acute aspiration bronchitis (6/44, 14% vs. 31/143, 22%; p = 0.242). Lower estimated glomerular filtration rate (adjusted odds ratio, 0.956; 95% confidence interval, 0.920-0.993) was significantly associated with the development of pneumonia. CONCLUSIONS Antibiotic administration should not be routinely recommended to prevent pneumonia following acute aspiration bronchitis, and patients with decreased renal function should be closely monitored. A randomized controlled trial is necessary to validate these results.

Abstract
Nosocomial pneumonia, or hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP) are important health problems worldwide, with both being associated with substantial morbidity and mortality. HAP is currently the main cause of death from nosocomial infection in critically ill patients. Although guidelines for the approach to this infection model are widely implemented in international health systems and clinical teams, information continually emerges that generates debate or requires updating in its management. This scientific manuscript, written by a multidisciplinary team of specialists, reviews the most important issues in the approach to this important infectious respiratory syndrome, and it updates various topics, such as a renewed etiological perspective for updating the use of new molecular platforms or imaging techniques, including the microbiological diagnostic stewardship in different clinical settings and using appropriate rapid techniques on invasive respiratory specimens. It also reviews both Intensive Care Unit admission criteria and those of clinical stability to discharge, as well as those of therapeutic failure and rescue treatment options. An update on antibiotic therapy in the context of bacterial multiresistance, in aerosol inhaled treatment options, oxygen therapy, or ventilatory support, is presented. It also analyzes the out-of-hospital management of nosocomial pneumonia requiring complete antibiotic therapy externally on an outpatient basis, as well as the main factors for readmission and an approach to management in the emergency department. Finally, the main strategies for prevention and prophylactic measures, many of them still controversial, on fragile and vulnerable hosts are reviewed.

Abstract
Although the lungs were considered to be sterile until recently, the advent of molecular biology techniques, such as polymerase chain reaction, 16 S rRNA sequencing and metagenomics has led to our expanding knowledge of the lung microbiome. These methods may be particularly useful for the identification of the causative agent(s) in cases of aspiration pneumonia, in which there is usually prior administration of antibiotics. The most common empirical treatment of aspiration pneumonia is the administration of broad-spectrum antibiotics; however, this may result in negative cultures from specimens taken from the respiratory tract. Therefore, in such cases, polymerase chain reaction or metagenomic next-generation sequencing may be life-saving. Moreover, these modern molecular methods may assist with antimicrobial stewardship. Based upon factors such as age, altered mental consciousness and recent hospitalization, there is a shift towards the predominance of aerobes, especially Gram-negative bacteria, over anaerobes in aspiration pneumonia. Thus, the therapeutic choices should be expanded to cover multi-drug resistant Gram-negative bacteria in selected cases of aspiration pneumonia.

Abstract
Aspiration pneumonia is a common cause of morbidity and mortality in both adults and children that, however, is difficult to accurately diagnose. In current literature, there are no reports or clinical research study focused on the possible use of lung ultrasound (LUS) in the diagnosis and follow-up of aspiration pneumonia in children. In this case series, we describe clinical, laboratory, radiological results as well as detailed lung ultrasound findings of three children with severe disability and diagnosed with aspiration pneumonia. In these three cases, albeit at different times, LUS played an important role in both the initial diagnostic process and follow-up.

Abstract
Although lung involvement in aspiration pneumonia typically has a gravity-dependent distribution on chest images, which patient’s conditions contribute to its radiological pattern has not been fully elucidated. This study was designed to determine the factors associated with the gravity-dependent distribution of community-acquired pneumonia (CAP) on chest computed tomography (CT). This retrospective study included elderly patients aged ≥ 65 years with CAP who underwent chest CT within 1 week before or after admission. The factors associated with lower lobe- and posterior-predominant distributions of ground glass opacity or airspace consolidation were determined. Of the 369 patients with CAP, 348 (94%) underwent chest CT. Multivariate analyses showed that impaired consciousness, a low Barthel index of activities of daily living, and high hemoglobin levels were associated with lower lobe-predominant distribution, while male sex and impaired consciousness were associated with posterior-predominant distribution. Cerebrovascular diseases were unrelated to these distributions. While male sex, impaired consciousness, high hemoglobin levels, low albumin levels, and the number of involved lobes were associated with in-hospital mortality, gravity-dependent distributions were not. Impaired consciousness might be the most significant predictor of aspiration pneumonia; however, the gravity-dependent distribution of this disease is unlikely to affect disease prognosis.

Abstract
Introduction The objective of this study was to clarify the clinical differences between nursing and healthcare-associated pneumonia (NHCAP) and community-acquired pneumonia (CAP) due to COVID-19. We also investigated the clinical characteristics to determine whether there is a difference between the variant and non-variant strain in patients with NHCAP due to COVID-19. In addition, we analyzed the clinical outcomes in NHCAP patients with mental disorders who were hospitalized in a medical institution for treatment of mental illness. Methods This study was conducted at five institutions and assessed a total of 836 patients with COVID-19 pneumonia (154 cases were classified as NHCAP and 335 had lineage B.1.1.7.). Results No differences in patient background, clinical findings, disease severity, or outcomes were observed in patients with NHCAP between the non-B.1.1.7 group and B.1.1.7 group. The median age, frequency of comorbid illness, rates of intensive care unit stay, and mortality rate were significantly higher in patients with NHCAP than in those with CAP. Among the patients with NHCAP, the mortality rate was highest at 37.5% in patients with recent cancer treatment, followed by elderly or disabled patients receiving nursing care (24.3%), residents of care facilities (23.0%), patients receiving dialysis (13.6%), and patients in mental hospitals (9.4%). Conclusions Our results demonstrated that there were many differences in the clinical characteristics between NHCAP patients and CAP patients due to COVID-19. It is necessary to consider the prevention and treatment content depending on the presence or absence of applicable criteria for NHCAP.

Abstract
OBJECTIVES To investigate the efficacy of an artificial intelligence (AI) system for the identification of false negatives in chest radiographs that were interpreted as normal by radiologists. METHODS We consecutively collected chest radiographs that were read as normal during 1 month (March 2020) in a single institution. A commercialized AI system was retrospectively applied to these radiographs. Radiographs with abnormal AI results were then re-interpreted by the radiologist who initially read the radiograph ("AI as the advisor" scenario). The reference standards for the true presence of relevant abnormalities in radiographs were defined by majority voting of three thoracic radiologists. The efficacy of the AI system was evaluated by detection yield (proportion of true-positive identification among the entire examination) and false-referral rate (FRR, proportion of false-positive identification among all examinations). Decision curve analyses were performed to evaluate the net benefits of applying the AI system. RESULTS A total of 4208 radiographs from 3778 patients (M:F = 1542:2236; median age, 56 years) were included. The AI system identified initially overlooked relevant abnormalities with a detection yield and an FRR of 2.4% and 14.0%, respectively. In the "AI as the advisor" scenario, radiologists detected initially overlooked relevant abnormalities with a detection yield and FRR of 1.2% and 0.97%, respectively. In a decision curve analysis, AI as an advisor scenario exhibited a positive net benefit when the cost-to-benefit ratio was below 1:0.8. CONCLUSION An AI system could identify relevant abnormalities overlooked by radiologists and could enable radiologists to correct their false-negative interpretations by providing feedback to radiologists. KEY POINTS • In consecutive chest radiographs with normal interpretations, an artificial intelligence system could identify relevant abnormalities that were initially overlooked by radiologists. • The artificial intelligence system could enable radiologists to correct their initial false-negative interpretations by providing feedback to radiologists when overlooked abnormalities were present.

Abstract
Atypical pneumonia is caused by atypical pathogens that are not detectable with Gram stain and cannot be cultured using standard methods. The most common causative organisms of atypical pneumonia are Mycoplasma pneumoniae, Chlamydia pneumoniae, and Legionella species. The therapeutic approach for atypical pneumonias is different than that for typical pneumonia. Typical bacterial pathogens classically respond to β-lactam antimicrobial therapy because they have a cell wall amenable to β-lactam disruption. On the contrary, most atypical pathogens do not have a bacterial cell wall, some are intracellular (e.g., Legionella), and some are paracellular (e.g., M. pneumoniae). To prevent an increase in the number of antimicrobial-resistant strains, the Japanese pneumonia guidelines have proposed a differential diagnosis for typical bacterial pneumonia and atypical pneumonia to select an appropriate antibiotic for the management of mild-to-moderate pneumonia. The guidelines have set up six parameters and criteria based on the clinical symptoms, physical signs, and laboratory data. However, in the elderly individuals and patients with underlying diseases, the differential diagnosis may be difficult or a mixed infection may be latent. Therefore, in these individuals, the administration of a β-lactam drug plus a macrolide or tetracycline, or only fluoroquinolone should be considered from the beginning to cover bacterial and atypical pneumonia.

Abstract
Aspiration pneumonia (AP) is a sub-type of community-acquired pneumonia (CAP) still poorly recognized especially in the absence of an aspiration event. A further difficulty is the differentiation between AP and aspiration pneumonitis. From a clinical perspective, AP is becoming increasingly relevant as a potential cause of severe and life-threatening respiratory infection among frail and very old patients, particularly among those with CAP requiring inpatient care. Moreover, AP is frequently underdiagnosed and a clear-cut definition of this pathological entity is lacking. There are different factors that increase the risk for aspiration, but other common factors influencing oral colonization such as malnutrition, smoking, poor oral hygiene or dry mouth, are also important in the pathogenesis of AP and should be considered. While there is no doubt in the diagnosis of AP in cases of a recent witnessed aspiration of oropharyngeal or gastric content, we here proposed a definition of AP that also includes silent unobserved aspirations. For this reason, the presence of one or more risk factors of oropharyngeal aspiration is required together with one or more risk factors for oral bacterial colonization. This proposed definition based on expert opinion not only unifies the diagnostic criteria of AP, but also provides the possibility to devise easily applicable strategies to prevent oral colonization.

Abstract
OBJECTIVES To compare the diagnostic accuracy of lung ultrasound (LUS) and standard chest X-ray (CXR) in older patients admitted to an acute-care geriatric ward for suspected acute pneumonia, and to develop an easy-to-use diagnostic tool, now called Pneumonia Lung Ultrasound Score (PLUS), for early risk stratification. DESIGN Prospective, single-center, cohort study. SETTING Acute-care geriatric ward of tertiary care center. PARTICIPANTS Individuals, aged 65 years and older, with suspected acute pneumonia. MEASUREMENTS Participants were stratified according to the Multidimensional Prognostic Index. All the patients underwent CXR and LUS, whereas chest computed tomography was performed in case of mismatch between LUS and CXR. Using logistic multivariate regression, we assessed the influence of age, sex, multimorbidity, cognitive impairment, and clinical biomarkers in the misdiagnosis of acute pneumonia. Finally, an easy-to-perform diagnostic tool based on the combination of biomarkers (brain natriuretic peptide, high-sensitivity C-reactive protein, and partial pressure arterial oxygen/fraction of inspired oxygen ratio) and LUS was realized. A receiver operating characteristic curve was used to verify the predictive accuracy of PLUS, CXR, and LUS in pneumonia diagnosis. RESULTS A total of 132 subjects (69% women; mean age = 85.3 ± 6.9 years) were enrolled in the study. Acute pneumonia was diagnosed in 94 of 132 cases. LUS showed higher diagnostic accuracy compared with CXR (0.91 (95% confidence interval (CI) = 0.85-0.93) vs 0.67 (95% CI = 0.58-0.75)) in detecting pneumonic consolidations. A higher degree of cognitive impairment was associated with both LUS and CXR pneumonia misdiagnosis (odds ratio = 1.30 (95% CI = 1.04-1.65)). PLUS showed higher predictive accuracy in the diagnosis of acute pneumonia compared with LUS (AUC = 0.92 (95% CI = 0.87-0.98) vs 0.86 (95% CI = 0.80-0.96); P = .029). CONCLUSIONS This study confirms the higher diagnostic accuracy of LUS compared with CXR for acute pneumonia in older adults. Nonetheless, the accuracy of PLUS, an easy-to-use, biomarker-derived diagnostic tool, was superior to LUS regardless of patients' degree of frailty.

Characteristic Factors of Aspiration Pneumonia to Distinguish from Community-Acquired Pneumonia among Oldest-Old Patients in Primary-Care Settings of Japan. Geriatrics (Basel) 2020; 5:E42. [PMID: 32645839 PMCID: PMC7555817 DOI: 10.3390/geriatrics5030042] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 06/29/2020] [Accepted: 07/03/2020] [Indexed: 01/08/2023] Open
Abstract
Background: Aspiration pneumonia (AsP), a phenotype of community-acquired pneumonia (CAP), is a common and problematic disease with symptomless recurrence and fatality in old adults. Characteristic factors for distinguishing AsP from CAP need to be determined to manage AsP. No such factorial markers in oldest-old adults, who are often seen in the primary-care settings, have yet been established. Methods: From the database of our Primary Care and General Practice Study, including the general backgrounds, clinical conditions and laboratory findings collected by primary care physicians and general practitioners, the records of 130 patients diagnosed with either AsP (n = 72) or CAP (n = 58) were extracted. Characteristic factors associated with the diagnosis of AsP were statistically compared between AsP and CAP. Results: The patients were older in the AsP group (median 90 years old) than in the CAP group (86 years old). The body temperature, heart rate, and diastolic blood pressure were lower in the patients with AsP than in those with CAP. Witnessed meal dysphagia by families and caregivers was reported only in AsP. Living in a nursing home, comorbidities of cerebral infarction and dementia (as positive factors) and hypertension (as a negative factor) were considered predictive to diagnose AsP in a stepwise logistic regression analysis. Conclusions: Among oldest-old adults in primary-care settings, living in a nursing home and the dysphagia risks are suggested to be characteristic factors for diagnosing AsP. Age and some relevant clinical information may help manage AsP and also be useful for families and caregivers.

Abstract
The number of aspiration pneumonia cases has increased in recent times. A definitive diagnosis of aspiration pneumonia is difficult in resource-limited settings where radiological equipment is unavailable. We report the initial diagnosis and subsequent monitoring of aspiration pneumonia in a home medical care setting. An 88-year-old Japanese male presented an acute onset of dyspnea, fever, and productive cough. At home, lung ultrasound displayed pleural effusion along with B-lines and subpleural consolidations. Upon admission, tests revealed increased total leucocyte counts with left-shifted neutrophils, elevated C-reactive protein levels, and positive sputum Gram stain. Chest X-ray imaging and computed tomography (CT) showed bibasilar infiltrates and wall thickening in the left S10 bronchi. The patient was diagnosed with aspiration pneumonia and treated with an antibiotic. After a 10-day hospitalization, lung ultrasound showed some remaining B-lines and disappearance of pleural effusion and subpleural consolidation. Chest X-ray image was normal, and CT revealed pleural abnormality and disappearance of bibasilar infiltrates, consistent with the ultrasound findings. Aspiration pneumonia develops with various clinical signs. However, diagnosis using chest X-ray imaging or CT in resource-limited settings is difficult. Ultrasound might allow physicians to make more accurate judgments, particularly while monitoring aspiration pneumonia following initial diagnosis in resource-limited settings.

Abstract
BACKGROUND There is an ongoing controversy on the role of the healthcare-associated pneumonia (HCAP) label in the treatment of patients with pneumonia. OBJECTIVE To provide an update of the literature on patients meeting criteria for HCAP between 2014 and 2018. SOURCES The review is based on a systematic literature search using PubMed-Central full-text archive of biomedical and life sciences literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM). CONTENT Studies compared clinical characteristics of patients with HCAP and community-acquired pneumonia (CAP). HCAP patients were older and had a higher comorbidity. Mortality rates in HCAP varied from 5% to 33%, but seemed lower than those cited in the initial reports. Criteria behind the HCAP classification differed considerably within populations. Microbial patterns differed in that there was a higher incidence of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa, and, to a lesser extent, enterobacteriaceae. Definitions and rates of multidrug-resistant (MDR) pneumonia also varied considerably. Broad-spectrum guideline-concordant treatment did not reduce mortality in four observational studies. The HCAP criteria performed poorly as a predictive tool to identify MDR pneumonia or pathogens not covered by treatment for CAP. A new score (Drug Resistance in Pneumonia, DRIP) outperformed HCAP in the prediction of MDR pathogens. Comorbidity and functional status, but not different microbial patterns, seem to account for increased mortality. IMPLICATIONS HCAP should no longer be used to identify patients at risk of MDR pathogens. The use of validated predictive scores along with implementation of de-escalation strategies and careful individual assessment of comorbidity and functional status seem superior strategies for clinical management.

Abstract
Pneumonia is a common cause of morbidity and mortality in adults in the United States. While pneumonia classically presents with a fever, cough, and shortness of breath, the presentation can vary widely in adults. This review evaluates history and physical examination findings of pneumonia and several conditions that mimic pneumonia. Pneumonia is a potentially deadly disease. History and examination findings are variable in pneumonia, and many conditions mimic pneumonia. These conditions include pulmonary embolism, diffuse interstitial lung disease, endocarditis, vasculitis, diffuse alveolar hemorrhage, acute decompensated heart failure, tuberculosis, lung cancer, and acute respiratory distress syndrome. Emergency clinicians should assess the patient while resuscitation occurs. Early antibiotics and the diagnosis of pneumonia can improve outcomes. Key historical and physical examination findings may lead the clinician to consider other conditions that require immediate management. Using clinical evaluation and adjunctive imaging, these conditions can be diagnosed and treated. Knowledge of pneumonia mimics is vital for the care of patients with respiratory complaints. Pneumonia is common and may be deadly, and emergency clinicians must differentiate conditions that mimic pneumonia. Rapid evaluation and management may alleviate morbidity and mortality for each of these conditions. The history and physical examination, in addition to utilizing imaging modalities such as ultrasound and computed tomography, are vital in diagnosis of pneumonia mimics.

Abstract
BACKGROUND Clinical practice guidelines for nursing- and healthcare-associated pneumonia (NHCAP) were developed for pneumonia caused by drug-resistant bacteria and pneumonia in elderly patients, particularly aspiration pneumonia. The identification of pathogenic bacteria and implementation of efforts to prevent the recurrence of aspiration pneumonia are very important in clinical practice. This study examined the extent to which clinicians have established bacteriological testing and recurrence prevention efforts for NHCAP and aspiration pneumonia. METHODS Questionnaire surveys were mailed to the heads of internal medicine and respiratory medicine departments at 2490 Japanese hospitals. The questionnaire evaluated bacteriological testing for NHCAP or aspiration pneumonia and prevention of the recurrence of aspiration pneumonia. RESULTS A total of 350 hospitals responded. These hospitals were grouped on the basis of whether a pulmonologist provided medical care for aspiration pneumonia and whether the hospital employed an infectious disease specialist. For hospitals in which pulmonologists treated aspiration pneumonia, the response rates for "is done in nearly all cases" were 70.0%, 84.7%, 31.6%, and 48.9% for sputum gram staining, sputum culture tests, blood culture tests, and pneumococcal vaccination, respectively. In hospitals that employed an infectious disease specialist, the response rates for "is done in nearly all cases" were 72.8% and 41.3% for sputum gram staining and blood culture tests, respectively. Recurrence prevention for aspiration pneumonia (other than pneumococcal vaccination) was not actively implemented. CONCLUSIONS Sputum gram staining, sputum culture tests, and other bacteriological tests were implemented quite actively. However, physicians who treat aspiration pneumonia should implement efforts to prevent pneumonia recurrence more actively.

Abstract
Waning immunity and declining anatomic and physiologic defenses render the elder vulnerable to a wide range of infectious diseases. Clinical presentations are often atypical and muted, favoring global changes in mental status and function over febrile responses or localizing symptoms. This review encompasses early recognition, evaluation, and appropriate management of these common infections specifically in the context of elders presenting to the emergency department. With enhanced understanding and appreciation of the unique aspects of infections in the elderly, emergency physicians can play an integral part in reducing the morbidity and mortality associated with these often debilitating and life-threatening diseases.
