Healthcare-Associated Pneumonia and Hospital-Acquired Pneumonia: Bacterial Aetiology, Antibiotic Resistance and Treatment Outcomes: A Study From North India

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 Background We aimed to compare the clinical characteristics of patients with community-acquired pneumonia (CAP), healthcare-associated pneumonia (HCAP), and hospital-acquired pneumonia (HAP) caused by Klebsiella pneumoniae and analyze the antimicrobial resistance and proportion of hypervirluent strains of the microbial isolates. Methods We conducted a retrospective study on patients with pneumonia caused by K. pneumoniae at the Taipei Veterans General Hospital in Taiwan between January 2014 and December 2016. To analyze the clinical characteristics of these patients, data was extracted from their medical records. K. pneumoniae strains were subjected to antimicrobial susceptibility testing, capsular genotyping and detection of the rmpA and rmpA2 genes to identify hypervirulent strains. Results We identified 276 patients with pneumonia caused by K. pneumoniae, of which 68 (24.6%), 74 (26.8%), and 134 (48.6%) presented with CAP, HCAP, and HAP, respectively. The 28-day mortality was highest in the HAP group (39.6%), followed by the HCAP (29.7%) and CAP (27.9%) groups. The HAP group also featured the highest proportion of multi-drug resistant strains (49.3%), followed by the HCAP (36.5%) and CAP groups (10.3%), while the CAP group had the highest proportion of hypervirulent strains (79.4%), followed by the HCAP (55.4%) and HAP groups (41.0%). Conclusion Pneumonia caused by K. pneumoniae was associated with a high mortality. Importantly, multi-drug resistant strains were also detected in patients with CAP. Hypervirulent strains were prevalent in all 3 groups of pneumonia patients, even in those with HAP.

Abstract Background In the present study we determined the prevalence of antibiotic resistance in the most common organisms causing healthcare-associated infections in tertiary-care hospitals in Belo Horizonte, a 3,000,000 inhabitants city from Brazil. Methods Microbiology data of hospital acquired infections (HAI) defined by the National Healthcare Safety Network (NHSN)/CDC protocols of seven general hospitals were analyzed: three public institutions, two philanthropic, and two private hospitals. Samples from different topographies were plate in an ideal culture medium and after growth, the microorganisms were identified by standard biochemical and microbiological methods, using the VITEK 2 compact system (Biomerieux), which allows the simultaneous identification of Gram-positive and Gram bacteria -negative and combine the identification and TSA results in a single report. Six hospitals used automated methods and one institution used manual method for antimicrobial susceptibility testing. Results Samples of seven Gram-negative and two Gram-positive bacteria collected between Dec/2019-Nov/2020 from HAI isolates were analyzed: 565 Klebsiella, 293 Escherichia coli, 153 Proteus, 403 Pseudomonas, 275 Acinetobacter, 174 Serratia, 153, 361 Staphylococcus aureus, and 176 Enterococcus. Antibiotic resistance profile of each strain is summarized in Figures 1, 2, and 3. Resistance profile: Klebsiella, E. coli, Proteus. ATB profile: Pseudomonas, Acinetobacter, Serratia. ATB profile: Enterobacter, S. aureus, Enterococcus . Conclusion Benchmarks for antibiotic resistance in the most common organisms causing healthcare-associated infections were defined, and can be used as indicators for healthcare assessment, specially in developing countries institutions.

Currently, the problem of prevention and treatment of healthcare-associated infections (HAI), only in hospitals from 5 to 20% of patients HAI get sick. In Chelyabinsk region, in comparison with the Russian Federation, the quantity of the infections connected with delivery of health care tends to growth. The greatest number of HAI is registered in hospitals of a surgical profile 70.3 ± 5.7% (in the Russian Federation - 31.4 ± 0.2%). In area hospital-acquired pneumonia steadily holds the first - second place in structure of HAI (38.2 ± 10.3%) in the country - the fourth - fifth (10.1 ± 5.1%). Detection of distinctions in structure of HAI in Chelyabinsk region and in the country in general demand further studying for the purpose of identification and introduction of the most effective preventive and antiepidemic actions.

Abstract Background Data in the literature about HSV reactivation in COVID-19 patients are scarce, and the association between HSV-1 reactivation and mortality remains to be determined. Our objectives were to evaluate the impact of Herpes simplex virus (HSV) reactivation in patients with severe SARS-CoV-2 infections primarily on mortality, and secondarily on hospital-acquired pneumonia/ventilator-associated pneumonia (HAP/VAP) and intensive care unit-bloodstream infection (ICU-BSI). Methods We conducted an observational study using prospectively collected data and HSV-1 blood and respiratory samples from all critically ill COVID-19 patients in a large reference center who underwent HSV tests. Using multivariable Cox and cause-specific (cs) models, we investigated the association between HSV reactivation and mortality or healthcare-associated infections. Results Of the 153 COVID-19 patients admitted for ≥ 48 h from Feb-2020 to Feb-2021, 40/153 (26.1%) patients had confirmed HSV-1 reactivation (19/61 (31.1%) with HSV-positive respiratory samples, and 36/146 (24.7%) with HSV-positive blood samples. Day-60 mortality was higher in patients with HSV-1 reactivation (57.5%) versus without (33.6%, p = 0.001). After adjustment for mortality risk factors, HSV-1 reactivation was associated with an increased mortality risk (hazard risk [HR] 2.05; 95% CI 1.16–3.62; p = 0.01). HAP/VAP occurred in 67/153 (43.8%) and ICU-BSI in 42/153 (27.5%) patients. In patients with HSV-1 reactivation, multivariable cause-specific models showed an increased risk of HAP/VAP (csHR 2.38, 95% CI 1.06–5.39, p = 0.037), but not of ICU-BSI. Conclusions HSV-1 reactivation in critically ill COVID-19 patients was associated with an increased risk of day-60 mortality and HAP/VAP.
