Atypical pathogens as etiologic agents in hospitalized patients with community-acquired pneumonia in Korea: a prospective multi-center study. Although the CURB-65 or the IDSA/ATS definition of severe pneumonia (2007) may be used, these standards do not have perfect predictive power, and their clinical usefulness has not been verified.

PIRO score for community-acquired pneumonia: a new prediction rule for assessment of severity in intensive care unit patients with community-acquired pneumonia. American Lung Association. Continuity of antibiotic therapy in patients admitted from the emergency department. Ultimately a total of four clinical practice guidelines including a domestic guideline published in 2009 and a consensus guideline on the management of community-acquired pneumonia in adults published by the Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) in 2007, which were the adaptation targets for domestic guidelines, were selected as adaptation targets. Patients who are severely ill and those with signs of respiratory failure, sepsis, and/or neutropenia must be stabilized before transfer. Weiss K, Low DE, Cortes L, Beaupre A, Gauthier R, Gregoire P, Legare M, Nepveu F, Thibert D, Tremblay C, Tremblay J. The 2011 ERS/ESCMID guideline has also mentioned a study that reported an association between increased mortality rates and cefuroxime use in patients with S. pneumoniae pneumonia accompanied by bacteremia [134]. Rhinovirus is the most commonly detected, and other respiratory viruses such as influenza, metapneumovirus, RSV, parainfluenza virus, and coronavirus are also relatively commonly detected [38,39]. Lee S, Bae S, Lee KJ, Yu JY, Kang Y. Anand N, Kollef MH. The following combination therapies may be performed. Daptomycin: another novel agent for treating infections due to drug-resistant gram-positive pathogens. The committee included as many associated medical institutions as possible. Whereas the Legionella urinary antigen test can only diagnose the L. pneumophila serogroup 1, PCR can diagnose all serogroups, and thus has higher sensitivity for Legionella diagnosis. Lee SJ, Lee MG, Jeon MJ, Jung KS, Lee HK, Kishimoto T. Atypical pathogens in adult patients admitted with community-acquired pneumonia in Korea. Early ambulation is recommended (level of recommendation: strong, level of evidence: high). For adults who may have contracted community-acquired pneumonia, does making a hospitalization decision according to hospitalization criteria produce good prognoses? Kollef MH, Sherman G, Ward S, Fraser VJ. Am J Respir Crit Care Med. 47(3):375-84. Surveillance for Legionnaires' disease: risk factors for morbidity and mortality. In addition, patients whose CRP levels did not decrease by over 50% at four days of treatment had a higher 30-day mortality rate, higher risk of ventilator and vasopressor use, and higher risk of complications of pneumonia such as pyothorax [204]. If tuberculosis is suspected based on clinical or radiographic findings, a sputum stain and tuberculosis test are performed. Chest radiograph findings indicating nonresolution of the infiltrate should raise the consideration of an endobronchial obstruction as a cause of postobstructive pneumonia or a pleural effusion. Septation is indicative of birous strands between the parietal and visceral pleura, as well as inefficient drainage through the drainage tube [56]. Antibiotic use or cessation of antibiotic use based on procalcitonin levels helps reduce the doses and duration of antibiotic use without increasing the risk of treatment failure and complications.

Steroid therapy may be considered for patients with severe community-acquired pneumonia accompanied by shock (level of recommendation: weak, level of evidence: low). An alternative to intubation for refractory hypoxemia may be use of continuous positive airway pressure (CPAP). Pleuropulmonary complications of Panton-Valentine leukocidin-positive community-acquired methicillin-resistant. In addition, to eliminate the possibility of pneumonia and underlying diseases in patients who do not show sufficient clinical improvements at 4-5 weeks after treatment, chest X-rays may be repeatedly obtained [202].

Boussekey N, Leroy O, Alfandari S, Devos P, Georges H, Guery B. Procalcitonin kinetics in the prognosis of severe community-acquired pneumonia. For patients with moderate community-acquired pneumonia, a blood culture, Legionella, S. pneumoniae urinary antigen test, and sputum gram smear and culture must be performed [77,78,79]. Table 4 summarizes the current antibiotic resistance of S. pneumoniae strains isolated in Korea. [QxMD MEDLINE Link]. However, patients who have bronchospasm with infection benefit from inhaled bronchodilators, administered by means of a. Korean J Intern Med.

It is associated with considerable morbidity and mortality, particularly in older adult patients and those with significant comorbidities. 345(19):1368-77. This standard is reported to have higher predictive power than the PSI 4 or CURB-65 3 [124]. For all inpatients with pneumonia, it is recommended to perform blood culture, and sputum gram smear and culture tests before antibiotic treatment as long as they are clinically indicated. Siempos II, Vardakas KZ, Kopterides P, Falagas ME. [QxMD MEDLINE Link]. Direct admission to an intensive care unit (ICU) is mandated for any patient with septic shock requiring intravenous infusion of vasopressors to support the blood pressure or with acute respiratory failure requiring intubation and mechanical ventilation. The test gives positive results starting on the first day a disease occurs, and the positivity continues for several weeks [84,85,86,87,88,89,90,91,92]. In vitro activity of cefditoren: antimicrobial efficacy against major respiratory pathogens from Asian countries. Prina E, Ranzani OT, Torres A. Community-acquired pneumonia. Radiol Clin North Am. Since tsutsugamushi disease and leptospirosis, which are febrile illnesses that usually occur in the fall, are sometimes accompanied by atypical pneumonia, when a patient has a febrile illness accompanied by pneumonia in the fall, pneumonia must be differentiated with the possibility of febrile illnesses in mind. 1985 Oct. 13(10):818-29.

Similar to 1918, the vast majority of deaths occurred in individuals younger than 65 years. Vaccination and other prevention guidelines are briefly discussed below. Miller WT, Jr, Mickus TJ, Barbosa E, Jr, Mullin C, Van Deerlin VM, Shiley KT. Bacterial complications of respiratory tract viral illness: a comprehensive evaluation. Skerrett SJ. However, in a randomized controlled study involving patients with septic shock, seven-day use of low-dose hydrocortisone reduced mortality rates in patients who had hypoadrenalism [196], and reduced mortality rates and the number of days on mechanical ventilation in patients with acute respiratory failure in addition to hypoadrenalism [197]. In fact, influenza vaccination for elderly individuals results in a 48-57% reduction of the rate of hospitalization for pneumonia and influenza. Advice from the designated infectious diseases and/or clinical microbiology services may be required Yes It has therefore become necessary to revise the current guideline on community-acquired pneumonia in Korea. Note the increased anteroposterior chest diameter, which is suggestive of chronic obstructive pulmonary disease (COPD). Therefore, in cases where tuberculosis cannot be eliminated, it is recommended to avoid the empirical use of fluoroquinolones. Most patients who are admitted to an ICU experience shock, or require mechanical ventilation. OVID-MEDLINE and OVID-EMBASE were used to search for foreign studies, and KMBase and KoreaMed were used to search domestic studies. For outpatients who are suspected of having antibiotic-resistant bacteria or bacteria that are difficult to treat empirically using common antibiotics, perform sputum gram smear and culture. A comparison of Maine and Michigan. [69], The influenza pandemic of 1918 was responsible for the deaths of approximately 40-50 million people worldwide (>600,000 deaths in the United States). Don't try to do everything you normally do and rest when you feel tired. For patients who do not require hospitalization, the use of -lactam alone, the combined use of -lactam and macrolide, or the use of respiratory fluoroquinolones as empirical antibiotics is recommended. the severity of their condition does not require intravenous antibiotics. 107(1A):34S-43S. Antibiotics . 2014 Dec;99(6):221-30. doi: 10.1136/archdischild-2013-304193. 346 (25):1971-7. Patterns of resolution of chest radiograph abnormalities in adults hospitalized with severe community-acquired pneumonia. Objective markers that can be used by clinicians to predict the death of patients with community-acquired pneumonia, or the severity of pneumonia in outpatient clinics, outpatient departments of medical institutions at the level of a hospital, and emergency departments may be useful for deciding whether to request hospitalization in a medical institution or to hospitalize a patient or not. Microbial aetiology of community-acquired pneumonia and its relation to severity. Musher DM, Thorner AR. A Legionella urinary antigen test is performed for patients with moderate or severe community-acquired pneumonia (level of recommendation: strong, level of evidence: moderate). What are the first choices of antibiotics in the outpatient treatment of patients who may have contracted community-acquired pneumonia? In a retrospective study secondarily conducted using the Community-Acquired Pneumonia Organization (CAPO) database registered at the multi-institutional phase-three clinical trial conducted in various countries, antibiotics that were effective against the causative bacteria of atypical pneumonia showed more excellent outcomes in terms of mortality rate and clinical progress [129]. Light RW. According to a prospective study that monitored 680 inpatients with pneumonia, the rate of mortality or readmission was 10.5% when a patient satisfied all conditions of clinical stability shown in Table 9 in the last 24 hours before discharge, but it increased to 13.7% with the odds ratio at 1.6 when the patient did not meet one of the conditions, and to 46.2% with the odds ratio at 5.4 if the patient did not satisfy two or more conditions [162]. Ramirez JA, Bordon J. Fluoroquinolones are associated with delayed treatment and resistance in tuberculosis: a systematic review and meta-analysis. Bruns AH, Oosterheert JJ, Prokop M, Lammers JW, Hak E, Hoepelman AI. Discussion of empiric antibiotic therapy should be based on hospitalization status. 2002 Dec. 122(6):2115-21. Legionella were especially more common for cases of moderate to severe pneumonia requiring ICU admission compared with other atypical pneumococcal bacteria. Accessed: January 14, 2011. Moderate: Future studies will have an important influence on the level of certainty about the estimated value of an effect, and the value may change. Influenza virus was the most common (n = 23, 38%), followed by RSV (n = 9, 15%), rhinovirus (n = 7, 12%), coronavirus (n = 6, 10%), adenovirus (n = 6, 10%), metapneumovirus (n = 5, 8%), parainfluenza virus (n = 3, 5%) [6]. Therefore, for the empirical antibiotic treatment of patients with severe community-acquired pneumonia requiring ICU admission, combination therapy is recommended over monotherapy. The community-acquired pneumonia guideline developed by the ATS/IDSA in 2007 proposes the new definition of severe pneumonia that requires ICU admission modified from the earlier definition proposed by the ATS in 2001 [15,123] (Table 8). KQ 18. When procalcitonin, CRP, mild regional pro-atrial natriuretic peptide (MR pro-ANP) levels were continuously measured in 75 patients with pneumonia, high levels of MR pro-ANP and procalcitonin levels were consistently observed in patients who developed complications or died [209]. It is recommended to use CRB-65 in clinics or outpatient clinics at the level of a hospital, and to use CURB-65 for patients who are in emergency departments or whose blood tests results are available (level of recommendation: strong, level of evidence: low). If intravenous antibiotics are given, review by 48 hours and consider switching to oral antibiotics if possible. In elderly patients and in patients with underlying cardiac disease, care must be employed to avoid aggressive fluid administration, which may cause volume overload. Bronchoscopy helps evaluate for airway obstruction due to a foreign body or neoplasm. Predicting mortality among older adults hospitalized for community-acquired pneumonia: an enhanced confusion, urea, respiratory rate and blood pressure score compared with pneumonia severity index. This is because whereas resistant bacteria that cannot be removed with existing antibiotics are increasing in number, less and less novel antibiotics are being developed.
