Project description:Few studies have addressed the pragmatic management of ambulatory patients with suspected community-acquired pneumonia (CAP) using a precise description of the disease with or without chest X-ray (X-ray) evidence.To describe the characteristics, clinical findings, additional investigations and disease progression in patients with suspected CAP managed by French General Practitioners (GPs).The patients included were older than 18 years, with signs or symptoms suggestive of CAP associated with recent-onset unilateral crackles on auscultation or a new opacity on X-ray. They were followed for up to 6 weeks. Descriptive analyses of all patients and according to their management with X-rays were carried out.From September 2011 to July 2012, 886 patients have been consulted by 267 GPs. Among them, 278 (31%) were older than 65 years and 337 (38%) were at increased risk for invasive pneumococcal disease. At presentation, the three most common symptoms, cough (94%), fever (93%), and weakness or myalgia (81%), were all observed in 70% of patients. Unilateral crackles were observed in 77% of patients. Among patients with positive radiography (64%), 36% had no unilateral crackles. A null CRB-65 score was obtained in 62% of patients. Most patients (94%) initially received antibiotics and experienced uncomplicated disease progression regardless of their management with X-rays. Finally, 7% of patients were hospitalised and 0.3% died.Most patients consulting GPs for suspected CAP had the three following most common symptoms: cough, fever, and weakness or myalgia. More than a third of them were at increased risk for invasive pneumococcal disease. With or without X-rays, most patients received antibiotics and experienced uncomplicated disease progression.
Project description:PurposeFor most guidelines, diagnosis of community-acquired pneumonia (CAP) is based on a combination of clinical signs and focal consolidation visible on chest radiographs (CRs). Our objective was to analyze antibiotic initiation by general practitioners for patients with suspected CAP according to CR.MethodsWe conducted a prospective cross-sectional study in general practice in France. From November 2017 to December 2019, adult patients with clinically suspected CAP after CR were included. Radiographs were categorized as CAP positive or CAP negative. We analyzed patient characteristics and antibiotic initiation according to CR results.ResultsA total of 259 patients were included in the study. Median age was 58.0 years (interquartile range, 41.0-71.0 years); 249 (96.1%) patients had not received antibiotics before inclusion, and 144 (55.6%) had a positive CR. Patients with positive CR were clinically more severe than those with negative CR, with longer-lasting symptoms. Antibiotics were initiated for 142/143 (99.3% [95% CI, 97.9%-100.0%]) patients with positive CR and 79/115 (68.7% [95% CI, 60.2%-77.2%]) with negative CR (P < .001). Among the 115 CR-negative patients, clinical characteristics that were significantly different between patients for whom antibiotics were initiated or not did not appear to be clinically relevant.ConclusionsFor patients with suspected CAP, general practitioners systematically took into account results of positive CRs to initiate antibiotics and took much less account of negative CRs. These results justify clarification of what should be done in cases of clinical suspicion of CAP without radiologic confirmation.
Project description:Community-acquired pneumonia (CAP) is the leading cause of infectious death in the world. Immune dysregulation during acute lung infection plays a role in lung injury and the systemic inflammatory response. Cytokines seem to be major players in severe lung infection cases. Here, we present a review of published papers in the last 3 years regarding this topic. The cytokine response during pneumonia is different in bacterial vs viral infections; some of these cytokines correlate with clinical severity scales such as CURB65 or SOFA. Treatment focused in the cytokine environment is an interesting area that could impact the prognosis of CAP. Some of the agents that have been studied as co-adjuvant therapy are corticosteroids, macrolides, and linezolid, but anyone of those have shown a clear or proven efficacy or have been recommended as a part of the standard of care for CAP. More studies designed to define the role of immunomodulatory agents, such as co-adjuvant therapy in pneumonia, are needed.
Project description:Community-acquired pneumonia causes great mortality and morbidity and high costs worldwide. Empirical selection of antibiotic treatment is the cornerstone of management of patients with pneumonia. To reduce the misuse of antibiotics, antibiotic resistance, and side-effects, an empirical, effective, and individualised antibiotic treatment is needed. Follow-up after the start of antibiotic treatment is also important, and management should include early shifts to oral antibiotics, stewardship according to the microbiological results, and short-duration antibiotic treatment that accounts for the clinical stability criteria. New approaches for fast clinical (lung ultrasound) and microbiological (molecular biology) diagnoses are promising. Community-acquired pneumonia is associated with early and late mortality and increased rates of cardiovascular events. Studies are needed that focus on the long-term management of pneumonia.
Project description:In this study, we sought to broaden our understanding of circulatory monocyte functions captured during the acute (on hospital admission; day0) and recovery (one month follow-up) stages of patients diagnosed with community-acquired pneumonia (CAP).
Project description:BackgroundAccording to guidelines, the diagnosis of pneumonia should be confirmed by chest x-ray, ensuring appropriate management and wise use of antibiotics. Our study aimed to describe use of x-rays by family doctors and patients following diagnosis of pneumonia in primary care practices in the north of Israel.MethodsThis was a retrospective database study including adults diagnosed with pneumonia, assessing rates of referral and actual use of chest x-rays. We examined rates of referral for chest x-rays and rates of adherence to the referral, according to age, gender, smoking status, comorbidities and distance of residence from the radiology facility.ResultsDuring one year there were 4,230 diagnosed cases of pneumonia in the practice, of which 2,503 were referred for chest x-rays, and 1,920 adhered to the referral (45% of those diagnosed with pneumonia). The rate of referral was higher when the radiology facility was located in the same city as the family doctor compared to outside the city (69.7% and 53.2%, p < 0.001). Patients aged 40-64 were referred more than patients aged 18-39 or 65+ (61.5% vs. 56.5% and 58.3%, p = 0.03). Actual use of chest x-rays (considering both referral and adherence) was more likely when the radiology facility was in the same health centre or city than when it was outside the city [OR = 2.4; 95% CI: 2.1-2.8]; patients aged 65 + or 40-64 were more likely to adhere to the referral for x-ray than those aged 18-39 [OR = 1.3; 95% CI: 1.1-1.6, OR = 1.2; 95% CI: 1.0-1.4, respectively].ConclusionAccessibility of radiology facilities seems to be an important factor associated with both doctors' decisions and patients' adherence to the referral for chest x-rays.

Project description:Community acquired pneumonia (CAP) is a leading cause of hospitalistion and is associated with high mortality and morbidity. Neutrophils from CAP donors display altered functions, and these altered functions are associated with adverse outcomes. We undertook an oberservational study of CAP in frail older adults and age matched controls to determine drivers of neutrophil dysfunction.
