Objective To explore the thromboembolic events and mortality in patients with different types of severe pneumonia, and to analyze the related high-risk factors. Methods A total of 161 severe pneumonia patients who admitted in intensive care unit from January 2018 to February 2023 were included in the study. The patients were divided into a COVID-19 group (n=88) and a community-acquired pneumonia (CAP) group (n=73) according to the type of pneumonia, and divided into a thrombosis group and a non-thrombosis group according to the occurrence of thrombosis. The patients were followed-up until discharge or in-hospital death, registering the occurrence of thrombotic events. Results During the in-hospital stay, 32.9% of CAP and 36.4% of COVID-19 patients experienced thrombotic events (P>0.05). In CAP group all the events (including 24 paitents) were venous thromboses, while in COVID-19 group 31 patients were venous and 3 were arterial thromboses (2 were cerebral infarction, and 1 with myocardial infarction). There were statistically significant difference in gender, age, venous thromboembolism score (VTE score), activated partial thromboplastin time (APTT), and procalcitonin (PCT) between the TE group and the Non-TE group. Logistic regression analysis showed that thrombotic events was associated with sex, age and APTT; gender (female: OR=2.47, 95%CI 1.13 - 5.39, P<0.05) and age (OR=1.04, 95%CI 1.01 - 1.07, P<0.05) were positively associated with thrombotic events. During the in-hospital follow-up, 44.3% of CAP patients and 42.5% of COVID-19 patients died (P>0.05). Receiver operator characteristic (ROC) curve analysis showed that APACHEⅡ score was more accurate in predicting mortality of severe pneumonia, and the area under the ROC curve (AUC) was 0.77 (95%CI 0.70 - 0.84, sensitivity 74.3%, specificity 68.1%), the AUC of the VTE score was 0.61 (95%CI 0.53 - 0.70, Sensitivity 31.4%, specificity 81.7%); the AUC of the creatinine was 0.64 (95%CI 0.56 - 0.73, sensitivity 72.9%, specificity 51.2%). While the Kappa value for kidney disease was 0.409 (P<0.05) presenting moderate consistency. Conclusions The incidence of thromboembolic events and mortality are high in patients with different types of severe pneumonia. Thrombophilia was associated with sex, age, and APTT. APACHEⅡ score, VTE score, and creatinine value were independent risk factors for predicting death from severe pneumonia.
Objective To investigate the clinical characteristics and risk factors associated with death in critically ill patients with severe community-acquired pneumonia( CAP) .Methods A retrospective analysis was carried out in 125 hospitalized patients with severe CAP admitted from July 2008 to February 2012. Earlier clinical features were compared between 109 survival patients and 16 dead patients, and logistic regression analysis was conducted. Results The death group had more underlying diseases than the survival group( P lt;0. 05) . The heart rate at admission in the death group was significantly higher than that in the survival group( P lt;0.05) . The ratio and number of complication, the highest temperature before admission, the platelet count, the arterial blood pH, PaO2 and PaO2 /FiO2 in the death group were significantly lower than those in the survival group( P lt; 0. 05) . Logistic regression analysis showed that the number of underlying diseases, heart rate and PaO2 were predictors of death in the patients with severe pneumonia. Conclusion The number of underlying diseases, heart rate and PaO2 has highly predictive value of death for severe CAP.
Objective To explore the effect of early rehabilitation treatment on complications and prognosis of elderly patients with sever pneumonia undergoing mechanical ventilation. Methods The patients who meeting the inclusion criteria were randomly divided into an early rehabilitation group and a control group, with 35 cases in each group. On basis of same routine treatment, the early rehabilitation group was treated with early rehabilitation. The early rehabilitation methods included exercise therapy, electrical stimulation therapy, swallowing therapy, cough training and wheelchair-bed transfer training, etc. The patients received individual training methods according to their conditions. The difference of two groups were observed in the rates of ICU-acquired weakness (ICU-AW), ventilator-associate pneumonia (VAP), the incidence of delirium, the mechanical ventilation time, ICU-hospital time, total hospital time, 30-day hospital mortality, extubation fail rate and tracheotomy rate. Results Compare with the control group, the incidence of ICU-AW (14.28% vs. 37.14%), VAP (8.57% vs. 28.57%), and delirium (40.00% vs. 65.71%) in the early rehabilitation group were significantly reduced (all P<0.05). The duration of delirium [(3.50±1.31) dvs. (6.40±1.47) d], the ventilation time [(6.32±2.19) d vs. (9.40±4.43) d], ICU hospitalization time [(10.80±3.64) d vs. (15.31±3.85) d] and total hospitalization time [(22.52±7.56) d vs. (30.22±11.54) d] of the early rehabilitation group were significantly lower than the control group (all P<0.001). The tracheotomy rate and 30-day hospital mortality of the early rehabilitation group were significantly lower than the control group (25.71%vs. 51.42% and 28.57% vs. 54.28%, both P<0.05). There was no significant difference in extubation fail rate (5.71%vs. 11.42%, P>0.05). In the early rehabilitation group, there were no complications such as pipe prolapse, limb injury or serious arrhythmia. Conclusion Early rehabilitation can reduce the incidence of ICU-AW, VAP, delirium in elderly patients with severe pneumonia, help to shorten the mechanical ventilation time, ICU hospitalization time and total hospitalization time, reduce extubation failure rate and tracheotomy rate, so it is safe and effective, and worthy of being popularized and applied.
ObjectiveTo analyze the clinical features of Legionella-associated cavitary pneumonia, and to explore the diagnosis, treatment planning, and clinical management of patients.MethodsThe data of a patient with severe Legionella-associated cavitary pneumonia were collected and analyzed. Databases including PubMed, Ovid, Wanfang, VIP and Chinese National Knowledge Infrastructure were searched for pertinent literatures, using the keyword "Legionella, lung abscess or cavitary pneumonia" in Chinese and English from Jan. 1990 to Jun. 2019. The related literature was reviewed.ResultsA 60-year-old male patient was admitted to hospital because of fever, cough, and expectoration for five days. On presentation, his temperature was 38.3 °C, and pulmonary auscultation revealed rales on the left side of the lungs. Culture of lower airway secretions obtained by bronchoscopy revealed Legionella pneumophila infection, and serotype 6. Chest computerized tomography showed a consolidation in the left lung and an abscess in the left upper lobe. The patient was discharged from the hospital after three months of anti-Legionella treatment (Mosfloxacin, Azithromycin, etc.). Fifteen manuscripts, including 18 cases, were retrieved from databases. With the addition of our case, a total of 19 cases were analyzed in detail. There were 15 males and four females, aged from 4 months to 73 years old. Most of them (14/19, 73.7%) were accompanied by multiple underlying diseases. Initial empiric antimicrobial therapy failed in 15 (78.9%) cases, and 7 (36.8%) patients required combination therapy. The courses of antimicrobial treatment were from 3 to 49 weeks. All except one patient were fully recovered and discharged from hospital.ConclusionsLegionella pneumonia with pulmonary abscess or cavity is rare and often presents with fever. Pulmonary imaging shows infiltration in the initial, but can be free of cavities or abscesses. Most patients have basic diseases. Severe patients often need to be treated in combination with antibiotics for long periods of time.
ObjectiveTo systematically review the effectiveness of Xuebijing injection combined with routine therapy versus routine therapy alone in treating severe pneumonia. MethodsDatabases including PubMed (1990-2013.4), EMbase (1990-2013.4), The Cochran Library (Issue 4, 2013), CNKI (1982-2013.4), WangFang Data (1990-2013.4), VIP (1989-2013.4) and CBM (1978-2013.4) were searched from inception to April, 2013, for randomized controlled trials (RCTs) on Xuebijing injection for severe pneumonia. Studies were screened according to the inclusion and exclusion criteria, data were extracted, and methodological quality was evaluated. Meta-analysis was then performed using RevMan 5.2 software. ResultsA total of 12 studies involving 860 patients were included. The results of meta-analysis showed that, routine therapy plus Xuebijing injection had higher total effective and excellent rates, and the combined therapy reduced the average hospitalization days, and they had better improvement in WBC, CRP, CPIS, IL-6, IL-8, TNF-α. ConclusionThis current evidence shows that Xuebijing injection has a better clinical efficacy in treating severe pneumonia. Traditional Chinese herbs with the function of "promoting blood circulation to remove blood stasis" may exert their pharmacological effects via a multi-target way in treating severe pneumonia, which have a great potential for both clinical work and scientific research. Due to the limited quality and quantity of the included studies, better designed RCTs are needed to support Xuebijing's clinical efficacy in the treatment of severe pneumonia.
Objective To verify the association between admission serum phosphate level and short-term (<30 days) mortality of severe pneumonia patients admitted to intensive care unit (ICU) / respiratory intensive care unit (RICU). Methods Severe pneumonia patients admitted to the ICU/RICU of Quanzhou First Hospital Affiliated to Fujian Medical University from November 2019 to September 2021 were included in the study. Serum phosphate was demonstrated as an independent risk factor for short-term mortality of severe pneumonia patients admitted to ICU/RICU by logical analysis and receiver operator characteristic (ROC) curve. The patients were further categorized by serum phosphate concentration to explore the relationship between serum phosphate level and short-term mortality. Results Comparison of baseline indicators at admission between the survival group (n=54) and the non survival group (n=46) revealed that there was significant difference in serum phosphate level [0.9 (0.8, 1.2) mmol/L vs. 1.2 (0.9, 1.5) mmol/L, P<0.05]. Logical analysis showed serum phosphate was an independent risk factor for short-term mortality. ROC curve showed that the prediction ability of serum phosphate was close to pneumonia severity index (PSI). After combining serum phosphate with PSI score, CURB65 score, and sequential organ failure score, the predictive ability of these scores for short-term mortality was improved. Compared with the normophosphatemia group, hyperphosphatemia was found be with significantly higher short-term mortality (85.7% vs. 47.3%, P<0.05), which is absent in hypophosphatemia (25.8%). Conclusions Serum phosphate at admission has a good predictive value on short-term mortality in severe pneumonia patients admitted to the ICU/RICU. Hyperphosphatemia at admission is associated with a higher risk of short-term death.
ObjectiveTo discuss the risk factors of acute respiratory distress syndrome (ARDS) in patients with severe pneumonia.MethodsData of 80 patients with severe pneumonia admitted in our ICU were analyzed retrospectively, and they were divided into two groups according to development of ARDS, which was defined according to the Berlin new definition. The age, gender, weight, Acute Physiology and Chronic Health EvaluationⅡscore, lactate, PSI score and LIPS score, etc. were collected. Statistical significance results were evaluated by multivariate logistic regression analysis after univariate analysis. Receiver operating characteristic (ROC) curve was plotted to analyze the predictive value of the parameter for ARDS after severe pneumonia.ResultsForty patients with severe pneumonia progressed to ARDS, there were 4 moderate cases and 36 severe cases according to diagnostic criteria. Univariate analysis showed that procalcitonin (t=4.08, P<0.001), PSI score (t=10.67, P<0.001), LIPS score (t=5.14, P<0.001), shock (χ2=11.11, P<0.001), albumin level (t=3.34, P=0.001) were related to ARDS. Multivariate logistic regression analysis showed that LIPS ［odds ratio (OR) 0.226, 95%CI=4.62-5.53, P=0.013］ and PSI (OR=0.854, 95%CI=132.2-145.5, P=0.014) were independent risk factors for ARDS. The predictive value of LIPS and PSI in ARDS occurrence was significant. The area under ROC curve (AUC) of LIPS was 0.901, the cut-off value was 7.2, when LIPS ≥7.2, the sensitivity and specificity were both 85.0%. AUC of PSI was 0.947, the cut-off value was 150.5, when PSI score ≥150.5, the sensitivity and specificity were 87.5% and 90.0% respectively.ConclusionsPSI and LIPS are independent risk factors of ARDS in patients with severe pneumonia, which may be references for guiding clinicians to make an early diagnosis and treatment plan.
Objective To explore the effects of Metabolic Syndrome (MS) and its components on the condition and prognosis of patients with Severe Pneumonia. Methods 306 patients with severe pneumonia admitted to the intensive care unit of Guangdong Provincial Hospital of Traditional Chinese Medicine from January 2020 to July 2023 were included as study subjects.The patients were divided into MS and non-MS groups according to whether they were combined with MS,and into survival and death groups according to 28-day prognosis,and the general data, laboratory indexes, condition and prognostic indexes of the two groups were compared; multifactorial logistic regression was used to analyze the independent risk factors for the prognosis of patients with severe pneumonia. ResultsThe levels of test indicators such as body mass index (BMI), fasting blood glucose (FBG), triglyceride (TG), blood lactate,white blood cell count(WBC),urea phosphate (Urea), creatinine (SCr),as well as the incidence of acute respiratory distress syndrome (ARDS), shock,multiple organ dysfunction syndrome (MODS), rate of endotracheal intubation and mortality, ICU treatment cost,and total treatment cost of the MS group were significantly higher than those of the non-MS group; the levels of high-density lipoprotein cholesterol (HDL-C) and oxygenation index (OI) of the MS group were significantly lower than those of the non-MS group (P<0.05).Multifactorial logistic regression analysis showed that the risk of death from severe pneumonia was 1.276 times higher in combined MS than in no combined MS (95%CI: 1.013, 5.114, P=0.047). Subgroup analyses also showed that the risk of death from non-viral severe pneumonia was 2.147 times higher in those with MS than those without (95%CI: 1.175, 8.428, P=0.023). ConclusionSevere pneumonia with MS may be more severe and may have a worse prognosis.
