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.
ObjectiveTo investigate the clinical characteristics and contribution factors in severe coronavirus disease 2019 (COVID-19).MethodsThe clinical symptoms, laboratory findings, radiologic data, treatment strategies, and outcomes of 110 COVID-19 patients were retrospectively analyzed in these hospitals from Jan 20, 2020 to Feb 28, 2020. All patients were confirmed by fluorescence reverse transcription polymerase chain reaction. They were classified into a non-severe group and a severe group based on their symptoms, laboratory and radiologic findings. All patients were given antivirus, oxygen therapy, and support treatments. The severe patients received high-flow oxygen therapy, non-invasive mechanical ventilation, invasive mechanical ventilation or extracorporeal membrane oxygenation. The outcomes of patients were followed up until March 15, 2020. Contribution factors of severe patients were summarized from these clinical data.ResultsThe median age was 50 years old, including 66 males (60.0%) and 44 females (40.0%). Among them, 45 cases (40.9%) had underlying diseases, and 108 cases (98.2%) had different degrees of fever. The common clinical manifestations were cough (80.0%, 88/110), expectoration (33.6%, 37/110), fatigue (50.0%, 55/110), and chest tightness (41.8%, 46/110). Based on classification criteria, 78 (70.9%) non-severe patients and 32 (29.1%) severe patients were identified. Significant difference of the following parameters was found between two groups (P<0.05): age was 47 (45, 50) years vs. 55 (50, 59) years (Z=–2.493); proportion of patients with underlying diseases was 27 (34.6%) vs. 18 (56.3%) (χ2=4.393); lymphocyte count was 1.2 (0.9, 1.5)×109/L vs. 0.6 (0.4, 0.7)×109/L (Z=–7.26); C reactive protein (CRP) was 16.2 (6.5, 24.0) mg/L vs. 45.3 (21.8, 69.4) mg/L (Z=–4.894); prothrombin time (PT) was 15 (12, 19) seconds vs. 18 (17, 19) seconds (Z=–2.532); D-dimer was 0.67 (0.51, 0.82) mg/L vs. 0.98 (0.80, 1.57) mg/L (Z=–5.06); erythrocyte sedimentation rate (ESR) was 38.0 (20.8, 59.3) mm/1 h vs. 75.5 (39.8, 96.8) mm/1 h (Z=–3.851); lactate dehydrogenase (LDH) was 218.0 (175.0, 252.3) U/L vs. 325.0 (276.5, 413.5) U/L (Z=–5.539); neutrophil count was 3.1 (2.1, 4.5)×109/L vs. 5.5 (3.7, 9.1)×109/L (Z=–4.077). Multivariable logistic analysis showed that there was positive correlation in elevated LDH, CRP, PT, and neutrophil count with the severity of the disease. Currently, 107 patients were discharged and 3 patients died. Total mortality was 2.7%.ConclusionsOld age, underlying diseases, low lymphocyte count, elevated CPR, high D-dimer and ESR are relevant to the severity of COVID-19. LDH, CPR, PT and neutrophil count are independent risk factors for the prognosis of COVID-19.
Objective To explore the value of CT guided percutaneous puncture, aspiration and drainage on diagnosis and treatment of local complications of severe acute pancreatitis (SAP). Methods Forty-three cases of SAP combined with pancreatic necrosis, peripancreatic hydrops, pseudocyst and abscess were analyzed, all of them underwent CT guided percutaneous puncture, aspiration and drainage. Results The punctures were performed on 43 SAP patients for sixty-four times, the success rate was 100%, and in 24 cases of them puncture were performed for diagnosis, the positive rate of fluid absorption by puncture was 100%. Forty-one of 43 cases (95%) received puncture and tube drainage, open operation was performed in one patient, one patient was automatically discharged. The remission rate of abdominal distension was 93% (40/43) and 16 of 43 cases (37%) were turned to open operation. The effective rate of drainage was 61% (25/41). Conclusion The puncture, aspiration and drainage guided by CT is an effective method in diagnosis and treatment of local complications in part of SAP cases.
Objective To investigate the pleural effusion lymphocyte subsets in patients with pneumonia complicated with pleural effusion and its relationship with the occurrence of critical illness. MethodsPatients with pneumonia complicated with pleural effusion (246 cases) admitted to our hospital from January 2020 to June 2022 were selected as the research subjects. According to the severity of pneumonia, they were divided into a critical group (n=150) and a non-critical group (n=96). After 1:1 matching by propensity score matching method, there were 60 cases in each group. The general data of the two groups were compared. CD3+, CD4+, CD8+, CD4+/CD8+ ratio were detected by flow cytometry. Multivariate logistic regression was used to analyze the risk factors of critical pneumonia, and a nomogram prediction model was constructed and evaluated. The relationship between PSI score and lymphocyte subsets in pleural effusion was analyzed by local weighted regression scatter smoothing (LOWESS). Results After matching, the differences between the two groups of patients in the course of disease, heat peak, heat course, atelectasis, peripheral white blood cell count (WBC), C-reactive protein (CRP), D-dimer (D-D), procalcitonin (PCT) and hemoglobin were statistically significant (P<0.05). Compared with the non-critical group, the proportion of CD3+, CD4+, CD4+/CD8+ cells in critical group was lower (P<0.05), and the proportion of CD8+ cells was higher (P<0.05). Combined atelectasis, increased course of disease, fever peak and fever course, increased WBC, CRP, D-D, CD8+ and PCT levels, and decreased CD3+, CD4+, CD4+/CD8+ and Hb levels were independent risk factors for the occurrence of critical pneumonia (P<0.05). The nomogram prediction model based on independent influencing factors had high discrimination, accuracy and clinical applicability. There was a certain nonlinear relationship between pneomonia severity index and CD3+, CD4+, CD8+ and CD4+/CD8+. Conclusions Lymphocyte subsets in pleural effusion are closely related to the severity of pneumonia complicated with pleural effusion. If CD3+, CD4+, CD8+ and CD4+/CD8+ are abnormal, attention should be paid to the occurrence of severe pneumonia.
Objective To study the epidemic and clinical characteristics of three clusters of early cases of severe acute respiratery syndrome (SARS) in Shenzhen. Methods To retrospectively investigate three clusters of patients. To extract data on clinical presentation and laboratory studies. Results In the first cluster, one patient with SARS in Shenzhen had visited Hong Kong twice in one week. He had felt initial cold and fever in Hong Kong on January 14, while the second case had been onset of SARS when he had been back from Hong Kong. There were 5 people infected in the second cluster at the same time 1 week after they visited their father in a hospital in GuangZhou. Among the three clusters, two clusters had not been infected in ShenZhen, they are inputted, and another cluster is not clear, but it maybe inputted. Three clusters are distributed, they all had high fever. Among them, five had total body muscular soreness and unproductive cough, four with headache, three chill, and two dizziness and pharyngalgia. Three cases had asthma and diarrhea 1 week after the onset of SARS, and progressed to ARDS. The six patients with SARS in Shenzhen People’s Hospital tested positive for coronavirus-related anti-body (IgG) in their plasma 10-15 d after the onset. This IgG titres in one patient remained high (1∶640) 120 days after the onset. Neutrophilia and lymphopenia occurred in patients who died. The more severe the patients’condition was, the higher was the level of LDH increased. Conclusion In three clusters, most patients had not infected in Shenzhen, they are inputted and distributed. That patients with SARS tested positive for coronavirus-related IgG in their plasma.
Objective To investigate the CT manifestation and clinical significance of the gastrointestinal tract involvement in acute pancreatitis (AP). Methods Two hundreds CT scans in 131 patients with acute pancreatitis between Jan. 1, 2009 and Jun. 30, 2009 were included into the study. Two radiologists analyzed the images retrospectively, paying attention to the CT features of the gastrointestinal tract involvement, such as the style, distribution, and so on. The correlation between gastrointestinal tract involvement and CT severity index, clinical severity grading, and turnover of acute pancreatitis were studied using a SPSS 14.0 for windows statistics software. Results The CT images in 109 (83.2%) patients showed gastrointestinal tract involvement, which distributing mainly stomach, duodenum, jejunum, and transverse colon, and showing mainly the gastrointestinal tract wall thickening and distension. The gastrointestinal tract involvement had positive correlation with CT severity index, clinical severity grading, and turnover of acute pancreatitis (r=0.689， P=0.000; r=0.584， P=0.000; r=0.346， P=0.000). Conclusions The gastrointestinal tract involvement is common complication in acute pancreatitis and concerns with severity and prognosis of the disease. As other extrapancreatic organs involvement, the gastrointestinal tract involvement has important value for severity assessment, prognosis evaluation, and therapeutic effect monitoring of acute pancreatitis.
