ABSTRACT

Objective:To explore the incidence of secondary hemophagocytic lymphohistiocytosis (sHLH) in elderly patients with severe SARS-CoV-2 infection, and to analyze and summarize its clinical features and risk factors for early identification of high-risk groups.Methods:A retrospective cohort study was conducted. From January to May 2020, No. 960 Hospital of People's Liberation Army, the Second Hospital Affiliated to Cheeloo College of Medicine of Shandong Province, the First Rehabilitation Hospital of Shandong Province, the Public Health Clinical Center Affiliated to Shandong University, and Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine received 248 patients over 60 years old who were diagnosed with severe SARS-CoV-2 infection during their assistance to Hubei or support for diagnosis and treatment of SARS-CoV-2 infection in Shandong Province. The clinical data of patients were collected. According to the hemophagocytic lymphohistiocytosis diagnosis scoring (HScore) criteria, the patients were divided into sHLH group (HScore > 169) and non-sHLH group (HScore < 98). The demographic data, clinical features, laboratory results, the proportion of organ failure and 60-day mortality of patients were collected and compared between the two groups. The risk factors of sHLH and 60-day death were evaluated through binary multivariate Logistic regression analysis in elderly patients with severe SARS-CoV-2 infection. The receiver operator characteristic curve (ROC curve) was plotted to analyze the diagnostic value of indicators only or combined for sHLH.Results:Among 248 elderly patients with severe SARS-CoV-2 infection, 82 patients with incomplete data and untraceable clinical outcomes, and 35 patients with HScore of 98-169 were excluded. Finally, 131 patients were enrolled in the final follow-up and statistics, including 25 patients in the sHLH group and 106 patients in the non-sHLH group. Compared with the non-sHLH group, plasma albumin (ALB), hemoglobin (Hb), lymphocyte count (LYM), platelet count (PLT), fibrinogen (Fib) and prealbumin (PAB) in the sHLH group were significantly reduced, while alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), MB isoenzyme of creatine kinase (CK-MB), serum creatinine (SCr), C-reactive protein (CRP), D-dimer, ferritin (Fer), lactate dehydrogenase (LDH), procalcitonin (PCT), cardiac troponin I (cTnI), triglycerides (TG), interleukin-6 (IL-6), total bilirubin (TBil) were significantly higher. The fever and fatigue in the sHLH group were more severe than those in the non-sHLH group, and the patients in the sHLH group had higher rates of shock, acute kidney injury, liver dysfunction, and cardiac injury than the non-sHLH group. The 60-day mortality of patient in the sHLH group was significantly higher than that in the non-sHLH group [84.0% (21/25) vs. 40.6% (43/106), P < 0.01]. Binary multivariate Logistic regression analysis showed that high Fer [odds ratio ( OR) = 0.997, 95% confidence interval (95% CI) was 0.996-0.998], D-dimer ( OR = 0.960, 95% CI was 0.944-0.977), LDH ( OR = 0.998, 95% CI was 0.997-0.999) and TG ( OR = 0.706, 95% CI was 0.579-0.860) were independent risk factors for sHLH in elderly patients with severe SARS-CoV-2 infection (all P < 0.01), while elevated Fer ( OR = 1.001, 95% CI was 1.001-1.002), LDH ( OR = 1.004, 95% CI was 1.002-1.005) and D-dimer ( OR = 1.036, 95% CI was 1.018-1.055) were independent risk factors for 60-day death of patients (all P < 0.01). The death risk of the sHLH patients was 7.692 times higher than that of the non-sHLH patients ( OR = 7.692, 95% CI was 2.466-23.987, P = 0.000). ROC curve analysis showed that a three-composite-index composed of LDH, D-dimer and TG had good diagnostic value for sHLH in elderly patients with severe SARS-CoV-2 infection [area under the ROC curve (AUC) = 0.920, 95% CI was 0.866-0.973, P = 0.000]. Conclusions:Elderly patients with severe SARS-CoV-2 infection complicated by sHLH tend to be critically ill and have refractory status and worse prognosis. High Fer, LDH, D-dimer and TG are independent risk factors for sHLH, and are highly suggestive of poor outcome. The comprehensive index composed of LDH, D-dimer and TG has good diagnostic value, and can be used as an early screening tool for sHLH in elderly patients with severe SARS-CoV-2 infection.

ABSTRACT

Coronaviruses are single-stranded RNA viruses that are common in animals. In the past 20 years, there have been three large-scale epidemics of coronaviruses, including severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and coronavirus disease (COVID). Heart disease is an independent risk factor for severe COVID. At the same time, SARS-CoV-2 infection is often complicated with myocardial injury, which is closely related to poor prognosis. The receptors of SARS coronavirus are angiotensin-converting enzyme 2 (ACE2) and CD209L, among which ACE2 is the main receptor, and ACE2 is abundant in the heart. The receptor of MERS-coronavirus is dipeptide peptidase 4 (DPP4), which is not expressed in myocardial cells, but existed in vascular endothelial cells and blood. These receptors are important factors for the myocardial injury caused by coronavirus infection.

ABSTRACT

BACKGROUND@#Vancomycin treatment failure against vancomycin-susceptible gram-positive cocci is not rare in the intensive care unit (ICU). One of the reasons for this is the substandard drug trough concentration. We aimed to examine the hypothesis that the target serum concentration could be reached earlier with a loading dose of vancomycin.@*METHODS@#This retrospective cohort study was conducted at our ICU between June 2018 and June 2020 and involved patients who were suspected of having, or confirmed to have, gram-positive cocci infection and treated with vancomycin. One group of the patients was administered a loading dose of vancomycin (loading group) and compared with the group that did not receive a loading dose (control group). The baseline characteristics, vancomycin serum concentrations, and clinical outcomes were collected and analyzed.@*RESULTS@#Fifty-five patients were finally included, of which 29 received a loading dose of vancomycin. The serum concentration of vancomycin before the second dose was significantly higher for the loading group than for the control group (10.3 ± 6.1 mg/L vs. 5.7 ± 4.4 mg/L, P = 0.002). The results for both groups were similar before the fifth dose (12.4 ± 7.3 mg/L vs. 10.3 ± 6.3 mg/L in the loading and the control groups, respectively; P = 0.251). The 28-day mortality was lower for the loading group than for the control group (6.7% vs. 34.6% in the loading and control groups, respectively; P = 0.026). No significant differences were observed in serum creatinine (Cr) concentrations of the two groups.@*CONCLUSION@#With the loading dose of vancomycin, the target serum concentration of vancomycin may be reached earlier without increasing the risk of acute kidney injury.@*TRIAL REGISTRATION@#https://www.chictr.org.cn; ChiCTR2000035369.

ABSTRACT

Prone position ventilation has become an important part of lung protective ventilation in acute respiratory distress syndrome (ARDS) patients. Timely and appropriate implementation can improve the mortality of such patients. The same is true for patients with critical coronavirus disease 2019 (COVID-19) patients, but safety assessment, control of implementation details and prevention of complications still need to be further standardized during the practical procedure of prone position ventilation. The purpose of this paper is to explain the specific requirements and key points of prone position ventilation in critical COVID-19 patients, in order to promote the application of prone position ventilation in the treatment of patients with critical COVID-19 and reduce the occurrence of related complications.

ABSTRACT

OBJECTIVE@#To determine the characteristics of postprandial proximal gastric acid pockets (PPGAPs) and their association with gastroesophageal acid reflux in patients with Barrett's esophagus (BE).@*METHODS@#Fifteen patients with BE (defined by columnar lined esophagus of ≥1 cm) and 15 healthy individuals that were matched for age, gender, and body mass index, were recruited. The fasting intragastric pH and the appearance time, length, lowest pH, and mean pH of the PPGAP were determined using a single pH electrode pull-through experiment. For BE patients, a gastroesophageal reflux disease questionnaire (GerdQ) was completed and esophageal 24-h pH monitoring was carried out.@*RESULTS@#The PPGAP was significantly longer (5 (3, 5) cm vs. 2 (1, 2) cm) and the lowest pH (1.1 (0.8, 1.5) vs. 1.6 (1.4, 1.9)) was significantly lower in patients with short-segment BE than in healthy individuals. The PPGAP started to appear proximally from the gastroesophageal pH step-up point to the esophageal lumen. The acidity of the PPGAP was higher in the distal segment than in the proximal segment. In short-segment BE patients, there were significant correlations between the acidity and the appearance time and length of the PPGAP. The length and acidity of the PPGAP were positively associated with gastroesophageal acid reflux episodes. The acidity of the PPGAP was associated with the DeMeester scores, the GerdQ scores, and the fasting intragastric pH.@*CONCLUSIONS@#In patients with short-segment BE, a PPGAP is commonly seen. Its length and acidity of PPGAP are associated with gastroesophageal acid reflux, the DeMeester score, and the GerdQ score in patients with short-segment BE.

ABSTRACT

Objective:To observe the morphological changes of carotid artery, thoracic aorta and superior mesenteric artery in spontaneously hypertensive rats(SHR), in order to further study the effect of Mangiferin on the expressions of inflammatory factors and monocyte chemoattract protein-1 (MCP-1)/c-chemokine receptor type 2 (CCR-2) pathway in SHR. Method:Forty spontaneously hypertensive rats were randomly divided into model group, benazepril group (10 mg·kg-1·d-1) and low, medium and high-dose mangiferin groups (25, 50, 100 mg·kg-1·d-1). Eight male WKY rats of the same age were selected as normal control group. Systolic blood pressure was observed every two weeks after eight weeks of administration. Morphology of carotid artery, thoracic aorta and superior mesenteric artery was observed by hematoxylin-eosin (HE) staining. Immunohistochemical assay (IHC) and Western blot were used to detect MCP-1 and CCR-2 protein expressions in thoracic aorta. MCP-1 and CCR-2 mRNA expression levels in thoracic aorta were detected by Real-time quantitative fluorescence PCR (Real-time PCR). Result:Compared with the normal group, the inflammatory cells in the model group increased significantly, the systolic blood pressure was significantly higher than that in the WKY group (PPPPConclusion:There are inflammation damages in carotid artery, thoracic aorta and superior mesenteric artery of spontaneously hypertensive rats. Mangiferin has an anti-inflammatory effect by possibly inhibiting the expressions of MCP-1/CCR-2 pathway in SHR vessels.

ABSTRACT

Objective To study the effect of light sedation and traditional sedation (moderate sedation with daily sedation interruption) on hemodynamic indexes and prognosis in critically ill patients after cardiac surgery. Methods A total of 134 patients who were ventilated delay after heart surgery in our hospital from January to June 2017 were enrolled in this study. The patients were randomly divided into light sedation group (RASS score-1-1, n=65) and traditional sedation group (RASS score -3--2, n=69). All patients received sufentanil for postoperative analgesia. The light sedation group received propofol and/or dexmedetomidine as sedative drugs after operation, and the conventional sedation group used midazolam for postoperative sedation. The hemodynamic indexes, the first time of weaning off the ventilator, the duration of mechanical ventilation and ICU stay were compared between the two groups. Patients with low cardiac output syndrome after surgery were analyzed in subgroups. Results (1) There were no significant differences in heart function, operative complications and other indicators between the two groups after surgery (all P>0.05). The low cardiac output syndrome was found in 12 patients in the light sedation group and 10 cases in the traditional sedation group. (2) Hemodynamic monitoring results displayed that the sedation/central venous oxygen saturation (SvO2/ScvO2) and cardiac index (CI) were higher after sedation than before sedation in both groups (all P<0.05), but there was no significant difference between the two groups (all P>0.05). Subgroup analysis showed that the SvO2/ScvO2index was higher in patients with low cardiac output syndrome in the traditional sedative group than that in the light sedation group (P<0.05). There was no difference in the SvO2/ScvO2 index in patients with non-low cardiac output syndrome between two groups. (3) Compared with the traditional sedation group, the first off-line time, the total mechanical ventilation after surgery and the ICU stay time were significantly shortened, and the incidence of postoperative delirium was decreased in the light sedation group (all P<0.05). Subgroup analysis showed that in patients with non-low cardiac output syndrome, the first off-line time, total postoperative mechanical ventilation time and total ICU stay were significantly shorter in the light sedation group than those in the traditional sedation group (all P<0.05). There was no significant difference in patients with low cardiac output syndrome between the two groups (P>0.05). Conclusion Patients with non-low cardiac output syndrome after cardiac surgery benefit significantly from the superficial sedative strategy, and the postoperative mechanical ventilation time and ICU residence time are reduced. The moderate sedation may contribute to the early cardiac function recovery in patients with low cardiac output syndrome.

ABSTRACT

Objective To evaluate the status of microcirculation and to compare the short-term prognosis after elective PCI for AMI between patients with poorly controlled type2 diabetes and patients without type 2 diabetes. Methods According to the clinical history and HbA1c values,all patients were divided into 2 groups:diabetic group (group A,n=24) and non-diabetic group (group B,n=32).Basic clinical data, left ventricular end diastolic diameter (LVEDD) and left ventricular shot ejection fraction (LVEF)immediately and 3 months after operation measured by echocardiography and the result of coronary angiography were compared between the two groups. The rate of MACE 3 months after PCI was also compared. A pressure-temperature sensor wire was used to measure the index of microcirculation resistance(IMR)immediately after PCI. Results 1.The mean IMR value in group A was higher than group B(29.12±7.45)vs.(22.74±6.87);P=0.011.The HbA1c levels has positive correlation with the IMR value(r=0.324;P=0.048). 2. The mean LVEDD and the mean LVEF Rad no signifi cant diff erence between two groups before PCI. The mean LVEDD of group A at 3 months after PCI was significantly larger than group B(52.3±4.8)mm vs.(48.6±5.1)mm,P=0.019,the mean LVEF of group A 3 months post PCI was lower than that of group B(48.6±7.3)% vs.(56.1±4.7)%,P=0.003.The mean increase in LVEDD at 3 months after PCI in group A was higher than group B(4.1±6.3)mm vs.(0.8±4.4)mm, p=0.005 and the mean increase in LVEF in group A was significantly lower than in group B(–1.9±6.8)% vs. (4.3±5.4)%,P=0.007. 3. HbA1chad positive correlation with LVEDD(r=0.324,p=0.048)and its increase at 3 months postoperatively(r=–0.422,P=0.005).4. Risk estimation found type 2 diabetes was an independent risk factor for poor recovery of LVEF. The MACE rate was signifi cantly higher in Group A than in Group B(35.7% vs.9.4%,P=0.018).Conclusions Patients with type2 diabetes were more prone to suffer from coronary microcirculatory dysfunction and had poor recovery of cardiac function. Poorly controlled type 2 diabetes was an independent risk factor for poor recovery of cardiac function and short-term prognosis was worse in diabetic patients who had elective PCI.

ABSTRACT

OBJECTIVE:To study the anti-inflammatory effect of Xinfeng capsule on adjuvant arthritis (AA) in rats. METH-ODS:70 SD rats were randomized into a normal control group(isovolumetric normal saline),a model control group(isovolumet-ric normal saline),a positive control TCM group [Qufeng zhitong capsule 0.4 g(crude drug)/kg],a positive control chemical medi-cine group(Leflunomide tablet 2.1 mg/kg)and groups of low,middle and high doses of Xinfeng capsule,which were respectively marked as groups A,B,C,D,E,F and G. All groups of rats except for Group A were given freund’s complete adjuvant intracu-taneous injection to establishe AA models,and from the 12th day after the inflammation was induced,were given the correspond-ing drug,ig,for 28 consecutive days. The degree of toe swelling and arthritis index were determined and calculated for all groups of rats before and after the administration. The contents of interleukin 1β(IL-1β) and tumor necrosis factor α(TNF-α) in serum and synovial membrane of all groups of rats were determined 24 h after the last administration,and pathomorphological changes of their ankles were observed by light microscope. RESULTS:Compared to group A,group B demonstrated higher degree of toe swelling,arthritis index and contents of IL-1β and TNF-α in serum and synovial membrane,with statistical significance(P<0.01). After the administration,the degree of toe swelling and arthritis index of groups C,D,E,F and G reduced,with statistical signifi-cance(P<0.05). Compared to group B,groups C,D,E,F and G showed lower degree of toe swelling,arthritis index and con-tents of IL-1β and TNF-α in serum and synovial membrane,with statistical significance(P<0.01 or P<0.05). Synovial membrane hyperplasia and inflammatory cell infiltration were noted in the ankle tissue of the rats in group B,and such symptoms were not so serious in groups C,D,F and G. CONCLUSIONS:Xinfeng capsule has anti-inflammatory effect for AA rats by a mechanism which may be related to accelerating synoviocyte apoptosis and inhibiting synovial membrane hyperplasia.
