Factors influencing success of external cephalic version and their clinical significance / 中华围产医学杂志

Objective:To analyze the factors influencing the success rate of external cephalic version (ECV) and to create a preoperative scoring scale for stratified management of pregnant women who were preparing for ECV.Methods:This prospective study was conducted on singleton pregnant women who underwent ECV without anesthesia in Fujian Maternity and Child Health Hospital from January 1, 2017, to December 31, 2019. Univariate (two independent samples t-test, Mann-Whitney U test, and Chi-square test) and multivariate logistic regression were used to screen the clinical characteristics affecting the success of ECV, and receiver operating characteristic (ROC) curve was used to determine the cut-off value and convert quantitative variables into dichotomous variables. The independent variables were scored according to the regression coefficient in multivariate logistic regression analysis, and then a preoperative scoring scale was created. The ROC curve was used to calculate the cut-off value for the scoring scale. The subjects were divided into low and high score groups according to the cut-off value. The area under the ROC curve was used for evaluating the effectiveness of the scale in predicting the success of ECV. The success rate of ECV, difficulty of the operation and mode of delivery were compared between the two groups. Results:A total of 1 338 pregnant women met the inclusion criteria during the study period. After the exclusion of 885 women, 165 refused ECV in favor of direct cesarean section, 27 spontaneously converted to cephalic position before ECV, 261 who voluntarily accepted ECV were finally enrolled. ECV succeeded in 202 cases and failed in 59. (1) Favorable factors for ECV without anesthesia were the distance between the fetal breech and ischial spine <－3.5 cm ( OR=0.177, 95% CI: 0.071-0.438, P=0.009), the sum of the fundal height and the station of the fetal breech based on the ischial spine <30.25 cm ( OR=0.225, 95% CI: 0.094-0.537, P=0.001), amniotic fluid index ≥12 cm ( OR=0.399, 95% CI: 0.164-0.969, P=0.042), the surgeon's ability to hold the fetal head or breech with one hand ( OR=0.241, 95% CI: 0.098-0.589, P=0.002; OR=0.219, 95% CI: 0.087-0.546, P=0.001), and the fetal head located on the right or left upper abdomen of the mother ( OR=0.184, 95% CI: 0.059-0.568, P=0.003; OR=0.253, 95% CI: 0.084-0.760, P=0.014). (2) The area under the ROC curve of the preoperative score for predicting the success of ECV was 0.881 (95% CI: 0.821-0.941) and the cut-off value was 5.5. The subjects were divided into low (0-5 scores) and high (6-11 scores) score groups and the area under the ROC curve for predicting the success of ECV by grouping was 0.843 (95% CI: 0.774-0.912). Compared with the low score group, the high score group had a shorter ECV duration [2.0 min (0.5-10.0 min) vs 10.0 min (0.9-25.8 min), Z=－6.83, P<0.001], less attempts [1.0 times (1.0-4.0 times) vs 3.0 times (1.0-5.0 times), Z=－8.41, P<0.001], higher success rate [92.7% (190/205) vs 21.4% (12/56), χ2=127.64, P<0.001], higher rate of vaginal birth [75.4% (147/195) vs 18.5% (10/54)] and lower cesarean section rate [24.6% (48/195) vs 81.5% (44/54)] ( χ2=58.70, P<0.001). Conclusions:Preoperative scoring based on the factors influencing the success rate of ECV (the distance between the fetal breech and ischial spine, the sum of the fundal height and the station of the fetal breech based on the ischial spine <30.25 cm, amniotic fluid index ≥12 cm, the surgeon's ability to hold the fetal head or breech with one hand, and the fetal head locating on the right or left upper abdomen of the mother) is conducive to the individualized evaluation of the difficulty and the success rate of ECV as well as the success rate of vaginal delivery after ECV, which can provide a reference for clinical stratified management of ECV patients.

Objective To investigate the distribution and drug resistance characteristics of pathogens in donors and recipients undergoing simultaneous pancreas-kidney transplantation (SPK). Methods Clinical data of 231 pairs of donors and recipients undergoing SPK were analyzed retrospectively. The pathogens of samples from donors and recipients were identified by VITEK-2 analyzer, and drug sensitivity test was performed by K-B method. The source distribution and composition ratio of pathogens in donor and recipient samples, distribution characteristics of multi-drug resistant organism, infection of recipients and drug resistance characteristics of pathogens were analyzed. Results A total of 395 strains of pathogens were cultured from 1 294 donor samples, and the detection rate was 30.53%. Gram-negative bacteria mainly consisted of klebsiella pneumoniae, Gram-positive bacteria mainly comprised staphylococcus aureus, and fungi primarily included candida albicans, respectively. In total, 2 690 strains of pathogens were cultured from 10 507 recipient samples, and the detection rate was 25.60%. Gram-negative bacteria mainly consisted of pseudomonas maltophilia, Gram-positive bacteria primarily comprised enterococcus faecalis, and fungi mainly included candida albicans, respectively. Among 395 pathogens of donors, 15 strains of methicillin-resistant staphylococcus aureus (MRSA), 16 strains of extended-spectrum β-lactamase (ESBL) positive drug-resistant bacteria, 8 strains of carbapenem-resistant pseudomonas aeruginosa (CR-PA), 21 strains of carbapenem-resistant acinetobacter baumannii (CR-AB), 2 strains of carbapenem-resistant enterobacteriaceae (CRE) and 1 strain of multiple-drug/pan-drug resistant pseudomonas aeruginosa (MDR/PDR-PA) were identified. Among 2 690 strains of recipient pathogens, 73 strains of ESBL positive drug-resistant bacteria, 44 strains of CR-PA, 31 strains of CR-AB and 3 strains of MDR/PDR-PA were detected. One recipient developed donor-derived infection, 69 cases of pneumonia, 52 cases of urinary tract infection, 35 cases of abdominal infection and 2 cases of hematogenous infection were reported within postoperative 1 year. Gram-negative bacteria were resistant to certain antibiotics. Gram-positive bacteria were sensitive to vancomycin. Fungi were sensitive to amphotericin B. Conclusions Gram-negative bacteria are the main pathogens of SPK recipients, which are resistant to certain antibiotics. Empirical use of antibiotics can be delivered before culture results are obtained. Subsequently, sensitive antibiotics should be chosen according to the culture results to improve the survival rate of SPK recipients.

Association between levels of thyroid-stimulating hormone and prognosis of patients admitted to intensive care units: an analysis using the MIMIC-Ⅲ / 中华危重病急救医学

Objective:To explore the association between levels of thyroid-stimulating hormone (TSH) on admission and prognosis of patients admitted to intensive care unit (ICU).Methods:The data were collected from patients who were admitted to the ICU of the Beth Israel Deaconess Medical Center in the United States from 2001 to 2012 with available TSH test records within 24 hours after the ICU admission via the Medical Information Mart for Intensive Care-Ⅲv1.4 (MIMIC-Ⅲv1.4). Information including gender, age, ethnicity, type of admission, mechanical ventilation (MV) or renal replacement therapy (RRT) received on admission, comorbidities, and TSH test records within 24 hours after the ICU admission were collected. The sequential organ failure assessment (SOFA) score, simplified acute physiology score Ⅱ (SAPS Ⅱ) and the comorbidities index Elixhauser (SID30) score were calculated according to the parameters. The primary outcome was hospital mortality. Differences in baseline characteristics and prognosis were examined between patients with normal TSH levels and abnormal TSH levels which was determined according to a dichotomous variable provided by the data. Multivariable Logistic regression was used to analyze the association between TSH levels and prognosis after adjusting for confounding factors. A sensitivity analysis was conducted which categorized the study population as three groups (i.e., decreased, normal, and elevated TSH levels) using the range of 0.30-3.00 mU/L as the normal range of TSH.Results:A total of 3 425 ICU patients were enrolled in the study, of which 2 692 (78.60%) were with normal TSH and 733 (21.40%) were with abnormal TSH. There was no statistically significant difference in gender, age, ethnicity, type of admission and the ratio of MV between the normal TSH and abnormal TSH groups. Compared with normal TSH group, the patients in abnormal TSH had a higher SOFA, SAPS Ⅱ and SID30 scores as well as the ratio of RRT [SOFA score: 4 (2, 7) vs. 4 (2, 6), SAPS Ⅱ score: 38.02±13.76 vs. 36.53±13.75, SID30 score: 11 (4, 22) vs. 11 (0, 20), RRT ratio: 5.32% (39/733) vs. 3.49% (94/2 692), all P < 0.05]. The hospital mortality of patients in normal TSH was significantly higher than that of those in abnormal TSH [9.82% (72/733) vs. 5.94% (160/2 692), P < 0.01]. After adjusting for confounding factors, abnormal TSH was significantly associated with hospital mortality [odds ratio ( OR) = 1.71, 95% confidence interval (95% CI) was 1.24-2.35, P = 0.001]. In the sensitivity analysis in which the range of 0.30-3.00 mU/L was used as the normal range of TSH, compared with normal TSH, decreased TSH ( OR = 2.36, 95% CI was 1.40-3.97, P = 0.001) and elevated TSH ( OR = 1.44, 95% CI was 1.05-1.98, P = 0.023) were both significantly associated with increased hospital mortality. Conclusion:An abnormal level of TSH within 24 hours after admitted to ICU is an independent risk factor for hospital mortality among ICU patients.

Clinical application of anticoagulation therapy after simultaneous pancreas and kidney transplantation: a single-center observational cohort study / 中华器官移植杂志

Objective:To explore the clinical efficacy of aspirin plus low molecule heparin for pancreatic thrombosis during simultaneous pancreas and kidney transplantation (SPK).Methods:A total of 129 patients aged 18 years or higher underwent SPK between September 2016 and March 2020.They were divided retrospectively into two groups of aspirin ( n=60) and heparin ( n=69) according to different anticoagulant regimens.The aspirin group received only aspirin 100 mg/d at Day 1 post-operation.The heparin group received subcutaneous injection of enoxaparin 2 000 AxaIU daily for 7 days and followed by aspirin and clopidogrel.Outcomes and complication rates were compared between two groups. Results:All operations were successful without any mortality.In aspirin group, there were 5 cases of pancreatic thrombosis and one patient underwent pancreatectomy.There was no pancreatic thrombosis in heparin group ( P=0.014). There were 8 cases of intestinal anastomotic bleeding in aspirin group and 19 cases in heparin group.Statistically significant inter-group difference existed ( P=0.048). However, no significant inter-group difference existed in delayed recovery or rejection. Conclusions:Heparin anticoagulation can significantly lower the incidence of pancreatic thrombosis after SPK.Despite a higher incidence of intestinal anastomotic bleeding, no serious complication occurs after conservative meaures.

Objective To analyze the risk factors for the occurrence of post transplantation diabetes mellitus (PTDM) in renal transplant recipients, establish a prediction model for PTDM and evaluate its prediction value. Methods Clinical data of 915 renal transplant recipients were retrospectively analyzed. According to the occurrence of PTDM, all recipients were divided into the PTDM group (n=78) and non-PTDM group (n=837). The main indexes of recipients were collected. The risk factors for the occurrence of PTDM in renal transplant recipients were analyzed by univariate and multivariate analysis. The prediction model for PTDM was established and its prediction value was evaluated. Results Family history of diabetes mellitus, body mass index (BMI), preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin were the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM was logit (P)=2.199×family history of diabetes (yes=1, no=0)+0.109×BMI+0.151×2 h postprandial blood glucose (mmol/L)+0.508×glycosylated hemoglobin (%)-9.123. The results of receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of these 4 predictors combined for predicting PTDM in renal transplant recipients was 0.830 [95% confidence interval (CI) 0.786-0.873], the cut-off value was 0.0608, the sensitivity was 0.821, the specificity was 0.700, and the Youden index was 0.521 (P < 0.05). Conclusions Family history of diabetes mellitus, BMI, preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin are the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM combined with4 predictors yield relatively high prediction value for PTDM.

Distribution of monocyte subtypes in peripheral blood of patients with thyroid-associated ophthalmopathy / 中华实验眼科杂志

Objective:To explore the distribution of different subsets of monocyte in peripheral blood of patients with thyroid-associated ophthalmopathy (TAO).Methods:A cross-sectional study was performed.Fifty-nine TAO patients and 30 healthy subjects were recruited continuously in Zhongshan Ophthalmic Center from January 2017 to December 2019.Clinical data of subjects were recorded, and the severity and activity of TAO were graded based on the criteria of NOSPECS and CAS.TAO patients were grouped according to clinical activity of TAO, and the patients were treated by triamcinolone acetonide (TA) injection or methylprednisolone pulse therapy (MPT) accordingly.Peripheral blood of the subjects was collected and monocytes were isolated.The proportion of different monocyte subsets was assayed by a flow cytometry.The differences in distribution of monocyte subsets between TAO group and normal control group, stable TAO group and active TAO group, TA injected group and MPT treated group were compared and analyzed.The study protocol was approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-Sen University (No.2014MEKY005), and the written informed consent was obtained from each subject before any medical intervention.Results:The proportion of classical monocyte (CMo) subset in TAO group was (81.77%±5.53)%, which was significantly lower than (84.35±5.83)% in the normal control group ( P=0.034); the proportion of intermediate monocyte (IMo) subset in the TAO group was (10.17±4.19)%, which was significantly higher than (7.69±4.09)% in the normal control group ( P=0.006); no significant difference was found in the proportion of non-classical monocyte (NMo) subset between the two groups ( P=0.892). The proportion of CMo subset in the active TAO group was (77.29±5.80)%, which was significantly lower than (82.64±5.03)% in the stable TAO group ( P<0.01), and the proportion of IMo subset in the active TAO group was (13.79±4.82)%, which was significantly higher than (9.20±3.56)% in the stable TAO group ( P<0.01); no significant change was found in the proportion of NMo subset between the two groups ( P=0.283). There was no difference in the proportion of different TAO subsets before and after TA injection ( P>0.05). In MPT treated group, the proportion of CMo subset in TAO patients was significantly increased and the proportion of IMo subset was significantly decreased (both at P<0.05); there was no significant difference in proportion of NMo subset before and after MPT treatment ( P=0.187). Conclusions:IMo subset is enriched in patients with TAO, and the IMo subset content varies over the disease activity.MPT may inhibit the shift of CMo subset towards IMo subset.

Objective To investigate the features and incidence of severe anti-N-methyl-D-aspartate receptor ( NMDAR) encephalitis in pediatric intensive care unit ( PICU) treated with therapeutic plasma exchange(TPE). Methods A retrospective study was conducted of children with severe anti NMDAR encephalitis admitted to PICU of Shanghai Children′s Hospital from July 2015 to June 2018. Demographic data,therapeutic regimens,clinical and laboratory data were analyzed. The one dose of replacement plasma was 50-70 ml/kg. The laboratory biomarkers, anti-NMDAR in serum and cerebrospinal fluid ( CSF) were measured before and after TPE treatment. Results Thirteen cases with anti-NMDAR encephalitis were analyzed. The main clinical features were seizures, unconsciousness, motor dysfunctions organ dysfunction included respiratory failure in 3 (23. 1%) patients and shock in 4 (30. 8%) cases. The average levels of PICU stays were[11. 0(5. 5,19. 0)] days. The conventional therapy included methylprednisolone,intrave-nous immunoglobulin (IVIG),antiepileptic,and immune-suppressants. Seven patients received conventional treatment,and 6 (46. 2%) cases combined TPE after unsatisfactory effect on 3 to 7 days conventional treat-ment. TPE dosage was 50-70 ml/kg body weight per times for 3-5 dosages. The Glasgow coma score(GCS) and pediatric risk of mortality Ⅲ( PRISM Ⅲ) of children after TPE treatment were signifcantly improved compared with those before TPE treatment[ GCS:7. 5(6. 0,9. 3) vs. 12. 5 (11. 5,13. 5),PRISM Ⅲ:15. 5 (9. 5,17. 5) vs. 11. 0(4. 5,12. 3),all P<0. 05]. The levels of anti-NMDAR antibody in both serum and CSF decreased significantly after TPE(all P<0. 05). Three cases (50. 0%) had anaphylaxis during TPE. Conclusion TPE could decease the levels of anti-NMDAR antibody in CSF and serum,improve psychiatric and neurologic symptoms. TPE may be a potential therapy in pediatric severe NMDAR encephalitis.

The duration of CVVHDF treatment was 46.0 (24.5, 48.0) h. The levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), blood lactic acid were significantly decreased after the CVVHDF treatment (0.4 (0.1, 28.8) vs. 142.0 (123.1, 1 454.6) ng/L, Z=-2.023, P=0.043; 0.1 (0.1, 9.3) vs. 1.7(1.1, 30.0) ng/L, Z=-2.023, P=0.043; 1.2(1.1,1.4) vs. 2.5(2.4, 2.7) mmol/L, Z=-2.041, P=0.041 respectively). Moreover, the lung, liver and kidney function were significantly improved as indicated by the ratio of PaO2 to FiO2 (380.0 (182.5, 397.5) vs. 160.0 (52.5, 185.0)mmHg (1 mmHg=0.133 kPa), Z=2.041, P=0.041), the level of total bilirubin ((14.9±1.3) vs. (86.4±9.9) μmol/L), and the levels of creatinine (2 cases: 24.0vs. 103.0 μmol/L, 38.0 vs. 142.0 μmol/L).@*Conclusion@#CVVHDF as an adjuvant therapy can rapidly reduce the levels of IL-6 and TNF-α,and improve the organ functions in children with KD complicated with MODS.

Efficacy of continuous blood purification in treatment of severe acute pancreatitis in children / 中华儿科杂志

Objective@#To explore the therapeutic role of bedside continuous blood purification(CBP) in children with severe acute pancreatitis(SAP).@*Method@#The clinical and laboratory data of 11 children with SAP who were admitted to Pediatric Intensive Care Unit (PICU) of Shanghai Children′s Hospital from June 2013 to May 2016 were analyzed, including using pediatric critical illness score (PCIS) and pediatric risk of score mortality (PRISM)-Ⅲ score to assessing the severity of the disease.For those patients with severe organ dysfunction, CBP treatment was used when conventional therapy was not efficient.The evolution and prognosis of the disease were observed and analyzed.The measurement data were analyzed by Wilcoxon signed rank test.@*Result@#From June 2013 to May 2016, 11 cases with SAP were treated in PICU, of whom 7 cases had combined multiple organ dysfunction syndrome(MODS). After conservative treatment for 12-24 h, 6 cases with SAP deteriorated aggressively and were treated with CBP.PRISMA and PRISMA flex machines were used with Gambro PRISMA filter, and continuous venovenous hemodiafiltration(CVVHDF) or high volume hemofiltration (HVHF) were chosen as the therapy model.All 6 SAP patients survived after bedside CBP treatment(the median time spent on CBP were 48.5(48.0, 55.5) h). The serum concentration of amylase before and after the CBP treatment were respectively 675(495, 1 334)vs.176(136, 246) U/L, lipase 551(385, 1 075)vs.143(117, 185) U/L, CRP 168(125, 192) vs. 67(28, 87) mg/L, and inflammatory cytokines(TNF alpha 67.2(51.0, 72.9)vs. 22.6(19.3, 31.0) ng/L, IL-6 47.8(35.2, 88.4)vs. 23.6(20.3, 42.9) ng/L, IL-10 21.3(16.8, 23.9)vs. 35.6(26.5, 38.6) ng/L), which were obviously improved after CBP treatment(all P<0.05). And after CBP treatment, partial pressure of oxygen(PaO2)/fraction of inspiration O2(FiO2) (192(101, 208)and 240(207, 267) mmHg, 1 mmHg=0.133 kPa), MAP (58.3(56.3, 62.5) and 83.3(74.0, 87.4) mmHg) and PCIS scores (66(62.5, 72)and 92(89, 94) scores) were higher (all P<0.05).@*Conclusion@#CBP in critically ill with SAP can rapidly reduce blood amylase and lipase, help to keep the stable internal environment, block the systemic inflammatory response, improve the organ functions and maintain the fluid balance.CBP treatment may be a potential therapy in children with SAP.

Extracorporeal membrane oxygenation rescue for critically ill children with cardiopulmonary failure / 中华急诊医学杂志

Objective To summarize the therapeutic effects of extracorporeal membrane oxygenation (ECMO) on critically ill children with severe cardiopulmonary failure.Methods The pediatric patients supported with ECMO admitted to pediatric intensive care unit (PICU) from December 2015 to August 2017 were enrolled in this study.The data of demographics of patients,diagnosis,indication for ECMO,the procedure of ECMO support,complications,and survival status were analyzed.Results A total of 17 pediatric patients including 9 male and 8 female with severe cardiopulmonary failure treated with ECMO were studied.The median of age was 24 (2,117) months,and the median of body weight was 12 (5,33) kg.The indications for initiation of ECMO were cardiovascular failure with poor response to conventional therapy and severe acute respiratory distress syndrome (ARDS) without any beneficial effect obtained from mechanical ventilation.The percutaneous cannulation was done under ultrasound guidance by a team of trained intensivists through right cervical vein and internal carotid artery resulting in veno-arterial extracorporeal membrane oxygenation support.The mean duration of ECMO support was 212.5 h with median 188.5 (3-924) h.All patients were treated with mechanical ventilation for prevention from pulmonary atelectasis.Of 17 patients,10 were coupled with continuous renal replacement therapy (CRRT) to keep fluid balance.As a result,11 children (64.7％) were successfully weaned from ECMO defined as survival for 24 h after ECMO,and 10 children (58.8％) were alive to discharge from hospital.One of 2 cardiac arrest cases treated with extracorporeal cardiopulmonary resuscitation (ECPR) was alive.During ECMO support,there were 41 adverse events happened including pressure ulcers (64.7％),thrombocytopenia (52.9％),bleeding (35.3％).Conclusions The survival rate at discharge was 58.8％ in pediatric patients with severe cardiopulmonary failure with poor response to conventional therapy.Our data suggest that ECMO support is an important rescue technique for pediatric critical illness.

Lung injury associated with severe Epstein-Barr virus (EBV) infection / 中华儿科杂志

<p><b>OBJECTIVE</b>Severe Epstein-Barr (EB) virus infection is potentially a devastating process that often leads to death encountered in pediatrics recently. Inappropriate control of EB virus replication may cause severe infection resulting in multiple organ dysfunction. However, little information is available on pulmonary complications associated with EB virus infection. The aim of the present study was to investigate severe EB virus (EBV) infection complicated with lung injury in pediatric intensive care unit (PICU), including clinical characteristics, laboratory or imaging feature and outcomes.</p><p><b>METHOD</b>A total of 45 children with severe EBV infection seen in PICU of Shanghai Children's Hospital between January 2011 and December 2014 were retrospectively reviewed. According to clinical characteristics and imaging feature, 45 children were divided into non-lung injury group (n =27), lung injury without pulmonary fibrosis group(n = 12) and pulmonary fibrosis group (n = 6).</p><p><b>RESULT</b>In totally 45 cases of severe EBV infection, 21 (46.7%) were male and 24 (53. 3%) were female, mean age was 2. 4 years; 18 cases were complicated with lung injury, including 8 male and 10 female, median age was 31. 2 months. All of 18 cases presented with fever and cough, 15 of them exhibited dyspnea,12 cases were complicated with gasping, and 6 cases with ARDS. Eight cases accepted mechanical ventilation for acute respiratory distress; 6 cases who developed pulmonary fibrosis had tachypnea, refractory hypoxemia and hypercapnia, severe pulmonary air leak. The average EBV-DNA level in peripheral blood was 4. 42 x 10(6) copies/ml (range: 3. 25 x 10(3) - 6.59 x 10(7) copies/ml). Anti-EBV antibodies were positive in 41 cases, 18 cases were positive (+) for VCA-IgM, 15 cases were VCA-IgG and EA-IgG (+), 8 cases VCA-IgM and VCA-IgG (+). The radiographic findings revealed pulmonary interstitial infiltrates in all 18 cases with lung injury, 4 cases with segmental consolidation and 2 cases showed pleural effusions. HRCT scanning found EBV associated fibrosis including multifocal patches and diffuse ground-glass attenuation in both lungs, reticular opacities and honeycombing changes were observed 4 weeks after illness onset. There were significant differences in respiratory failure, PICU stay (days), Pediatric risk of mortality III (PRISM III) and pediatric clinical illness score(PCIS), serum TNF-α, EBV-DNA levels, percentage of NK cells and CD4+/CD8+ T cell ratio among non-lung injury group, lung injury without pulmonary fibrosis group and pulmonary fibrosis group (X2 =27. 12, F = 85. 23, 78. 23, 88. 68, 323. 80, 7. 35, χ2 = 6. 71, 12. 15; all P < 0. 05). COX regression analysis revealed that EBV-DNA and serum TNF-α levels were correlated with pulmonary fibrosis significantly (OR = 3. 92, P = 0. 04; OR = 5. 95, P = 0. 01). The patients with EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) had higher incidence of pulmonary fibrosis compared with non-EB-HLH (70% vs. 13%, χ2 = 4. 82, P = 0. 03). Of 18 cases, 8 cases died, including 3 cases with pulmonary fibrosis. The surviving cases with pulmonary fibrosis needed longer additional oxygen. Chest HRCT imaging of 3 cases with pulmonary fibrosis was improved at 6 months and oxygen therapy was discontinued at 18 months after discharge.</p><p><b>CONCLUSION</b>EB virus infection complicated with lung injury had higher incidence of respiratory failure, pulmonary fibrosis with a fatal outcome. EBV-DNA and serum TNF-α level were found to be statistically significant indicators of pulmonary fibrosis. Pulmonary fibrosis associated with severe EB virus infection may be reversible.</p>

Noninvasive pulmonary arterial pressure monitoring in the children with severe pneumonia and respiratory failures and its significance / 中华实用儿科临床杂志

Objective To evaluate the value of noninvasive monitoring of pulmonary arterial pressure in the children with severe pneumonia and respiratory failure.Methods A prospective study was adopted to investigate 69 patients who suffered from severe pneumonia and respiratory failure in Pediatric Intensive Care Unit in Shanghai Children's Hospital from June 2013 to December 2013 were involved in this study,except for heart disease.The pulmonary arterial pressure (PAP) and cardiac function were monitored by using bedside color doppler ultrasound cardiogram,such as PAP,cardiac index (CI),left ventricle ejection fraction(LEFT),and heart early diastolic filling velocity maximum/heart late diastolic filling velocity maximum (E/A ratio).They were divided into 2 groups according to PAP,one group as pulmonary arterial pressure normal group,the other group as pulmonary arterial hypertension(PAH) group,and the impact of the PAP on the prognosis and mechanical ventilation was assessed.Milrinone[0.5 μg/(kg · min)] were given the patients who were combined with pulmonary hypertension,and the PAP and cardiac function before using Milrinone and 24 h,48 h and 72 h after giving medicine was observed.Results Among 69 cases,40 cases were male and 29 cases were female,age ranging from 2 months to 12 years old,and the weight range was (14.3 ± 8.9) kg.The pediatric critical illness score(PICS) was 70.5 ± 9.6,and the pediatric risk of score m ortality Ⅲ was 13.5 ± 5.0.Among 69 cases,46 cases had pulmonary arterial hypertension,38 cases of them experienced mechanical ventilation,and 9 cases died.Among 23 cases who had no pulmonary arterial hypertension,only 8 cases experienced mechanical ventilation.There was a significant difference in the mechanical ventilation rate and mortality between two groups(x2 =15.78,P ＜0.0l ; x2 =5.18,P ＜ 0.05).The mechanical ventilation time was longer in pulmonary arterial hypertension group (t =3.89,P ＜0.01).PAP was (58.23 ±5.44) mmHg(1 mmHg =0.133 kPa),(49.10 ±4.69) mmHg,(42.53 ±4.54)mmHg and(35.63 ±4.78) mmHg respectively before and after using Milrinone 24 h,48 h and 72 h in 46 cases with pulmonary arterial hypertension,and the pressure decreased significantly after using medicine (F =67.11,P ＜ 0.01).There was no significant difference in CI,LVEF and E/A(all P ＞0.05).However,9 cases of them did not show any response to Milrinone,and in the end they couldn't live without mechanical ventilation,they died.Conclusions Noninvasive pulmonary arterial pressure monitoring could be beneficial in judging patient's condition and assessing prognosis of children with severe pneumonia and respiratory failure,and milrinone could decrease PAP.
