Objective To explore risk factors of stroke-associated pneumonia (SAP) for elderly stroke patients in ICU, and analyze the predictive value of human leukocyte antigen-DR (HLA-DR) on monocytes for SAP. Methods During January 2015 to August 2016, 155 elderly patients with stroke were recruited. The level of monocyte HLA-DR expression was measured after admission and the incidence of SAP was recorded. The risk factors for SAP were analyzed by univariate and multivariate analysis. ROC curve was drawn to analyze prognostic value of HLA-DR. Results SAP occurred in 75 cases with occurrence rate of 48.4%, including 42 early-onset cases and 33 later-onset cases. Age (OR=11.532), Glasgow Coma Scale (OR=7.124), dysphagia (OR=8.846), mechanical ventilation (OR=15.184), atrial fibrillation (OR=7.869), smoking history (OR=11.784), diabetes (OR=7.185) were independent risk factors (all P<0.05). The expression rate of monocyte HLA-DR in the SAP patients was significantly lower than those in the patients without SAP (allP<0.05). Through the ROC curve analysis, the expression rate of HLA-DR that below 78.65% was the optimum cut-off value for prediction of SAP with the area under ROC curve of 0.922, the sensitivity of 80.0% and the specificity of 85.0%. The sensitivity to predict early-onset SAP was 90.5% (38/42), and to predict later-onset SAP was 66.7% (22/33). Conclusions Age, severe coma, dysphagia, mechanical ventilation, atrial fibrillation, smoking history and diabetes are risk factors for SAP in elderly stroke patients in ICU. The detection of monocyte HLA-DR has reference value for early prediction of SAP especially for early-onset SAP with higher sensitivity.
ObjectiveTo systematically evaluate the efficacy of fiberoptic bronchoscopy for patients with stroke-associated pneumonia (SAP).MethodsAll randomized controlled trials on fiberoptic bronchoscopy in treating SAP were collected from Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure, Chinese Biology Medicine database, Wanfang database, and Chongqing VIP database. Two reviewers screened the literature, extracted data, and assessed the methodological quality of included studies. And then meta-analysis was conducted using RevMan 5.3 software.ResultsTwelve studies with 1 107 patients were included. Compared with the routine therapy, the fiberoptic bronchoscopy combined with routine therapy showed a better efficacy [relative risk (RR)=1.26, 95% confidence interval (CI) (1.17, 1.36), P<0.000 01], and indicated a shorter hospital-stay [mean difference (MD)=–4.29 days, 95%CI (–5.06, –3.52) days, P<0.000 01] and lower Clinical Pulmonary Infection Score values [MD=–1.13, 95%CI (–1.77, –0.49), P=0.000 5]. Meanwhile, a downward trend in the level of procalcitonin [standardized mean difference (SMD)=–3.86, 95%CI (–4.22, –3.50), P<0.000 01], tumor necrosis factor α [SMD=–2.75, 95%CI (–3.84, –1.66), P<0.000 01], and C-reactive protein [SMD=–2.55, 95%CI (–3.83, –1.26), P=0.000 1], as well as a higher level of partial pressure of oxygen in arterial blood [MD=15.34 mm Hg (1 mm Hg=0.133 kPa), 95%CI (6.38, 24.31) mm Hg, P=0.000 8] appeared after the combined treatment.ConclusionBased on the conventional therapy, the treatment of fiberoptic bronchoscopy can improve the efficacy, shorten the hospital stay, relieve the systemic inflammatory responses, and improve the oxygenation of SAP patients.
ObjectiveTo explore the risk factors of stroke-associated pneumonia in stroke inpatients at rehabilitation stage.MethodsA retrospective survey was conducted to collect the general clinical data of 271 patients with stroke who were hospitalized for the first time between January 2017 and December 2018. They were divided into two groups according to the presence or absence of pneumonia. The general clinical data of the two groups were observed and analyzed, including sex, age, length of stay, course of disease, Brunnstrom Stage, Barthel Index, scores of Kubota’s Water Drinking Test, indwelling gastric tube, cognitive impairment, aphasia, hypertension history, diabetes history, history of smoking and drinking, albumin content, and hemoglobin content. Statistically significant factors were screened out from single factor analysis, and then multivariate logistic regression analysis was conducted.ResultsThere were significant differences in age, length of stay, Barthel Index, Brunnstrom Stage (upper limb, hand and lower limb), scores of Kubota’s Water Drinking Test, indwelling gastric tube, albumin content, hemoglobin content, cognitive impairment, and aphasia between the two groups (P<0.05). Multivariate logistic regression analysis showed that indwelling gastric tube [odds ratio=52.463, 95% confidence interval (4.154, 662.658), P=0.002] was an independent risk factor for pneumonia.ConclusionsIndwelling gastric tube is an independent risk factor for pneumonia. In view of the risk factor, taking active and effective preventive measures can help prevent pneumonia.
ObjectiveTo explore the risk factors of stroke-associated pneumonia (SAP) in the patients with acute ischemic stroke, in order to provide effective guidance for clinical prevention and treatment.MethodsFrom November 2016 to November 2019, 330 patients with acute ischemic stroke admitted to the Department of Neurology of West China Hospital of Sichuan University and the Department of Neurology of the Sixth People’s Hospital of Chengdu were selected as the research object. The clinical data of the patients were analyzed retrospectively. According to whether SAP occurred, they were divided into infected group and non-infected group. Multivariate logistic regression model was used to analyze the risk factors of SAP.ResultsA total of 71 cases of SAP occurred in patients with acute ischemic stroke, accounting for 21.52%. Logistic regression analysis showed that age≥70 years old [odds ratio (OR)=3.677, 95% confidence interval (CI) (1.452, 9.311), P=0.006], chronic lung disease [OR=4.985, 95%CI (1.558, 15.952), P=0.007], disturbance of consciousness [OR=7.147, 95%CI (1.617, 31.587), P=0.009], bulbar palsy [OR=5.909, 95%CI (2.668, 13.089), P<0.001], the use of nasal feeding tube [OR=7.427, 95%CI (1.681, 32.812), P=0.008] were independent risk factors for SAP in patients with acute ischemic stroke.ConclusionsAge≥70 years old, chronic lung disease, disturbance of consciousness, bulbar paralysis and use of nasal feeding tube are independent risk factors for SAP. It is necessary to strengthen the management of these risk factors in order to identify high-risk patients with SAP early, and develop intervention strategies for risk factors, so as to improve the prognosis.
ObjectiveTo systematically analyse the application of pulmonary rehabilitation in patients with stroke-associated pneumonia (SAP), in order to provide reference for clinical healthcare professionals to carry out relevant interventions. Methods PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang, Chongqing VIP, and SinoMed were systematically searched, with a search period from database establishment until December 31, 2023. The scoping review method was used to analyze the included studies. Results A total of 16 studies were included, mainly randomized controlled trials and quasi-experimental studies. The research mainly focuses on China and South Korea. The sample size was generally 40-80 cases. The duration of intervention is mostly 2-4 weeks. Six different lung rehabilitation interventions were involved. The main outcome measures included lung function, incidence of SAP, mortality rate, cognitive function, severity of stroke, length of intensive care unit stay, duration of antibiotic use, and daily living activity. Most studies had shown that lung rehabilitation has a significant impact on SAP patients.Conclusions The effectiveness of pulmonary rehabilitation in SAP patients has been preliminarily validated. Future research needs to cover a wider range of regions and larger samples, and conduct long-term tracking studies and multidimensional evaluations to enhance the universality and reliability of the results.
