OBJECTIVETo study the expression of serum cytokines, interleukin-38 (IL-38) and interleukin-1β (IL-1β) in the acute phase of Kawasaki disease (KD) in children and the association of IL-38 and IL-1β with inflammatory response in the acute phase and the development of coronary artery lesion (CAL).

METHODSA total of 40 children with KD who were hospitalized in the hospital between July 2015 and June 2016 were enrolled, with 21 children in the CAL group and 19 in the non-CAL (NCAL) group. Thirty healthy children and 19 children with infection and pyrexia, who were matched for sex and age, were enrolled as healthy control group and pyrexia control group respectively. ELISA was used to measure the serum levels of IL-38 and IL-1β in the 40 children in the acute phase of KD. Spearman's rank correlation analysis was used to investigate the correlations of IL-1β and IL-38 with interleukin-6 (IL-6), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), N-terminal pro-brain natriuretic peptide (NT-proBNP), triglyceride (TG), and total cholesterol (TC).

RESULTSThe serum level of IL-38 in the children in the acute phase of KD was significantly lower than that in the healthy control group (P<0.05), but significantly higher than that in the pyrexia control group (P<0.05). There was no significant difference in the level of IL-38 between the CAL and NCAL groups (P>0.05). The children in the acute phase of KD had a significantly higher level of IL-1β than the healthy control group (P<0.05), while there was no significant difference between this group and the pyrexia control group (P>0.05). There was also no significant difference in the level of IL-1β between the CAL and NCAL groups (P>0.05). Serum IL-1β and IL-38 levels were not correlated with serum levels of CRP, ESR, PCT, IL-6, and NT-ProBNP or blood lipids (TG and TC) (P>0.05).

CONCLUSIONSIL-38 is involved in an inflammatory response in the acute phase of KD and may exert an anti-inflammatory effect, which is opposite to the effect of IL-1β to promote inflammatory response. However, there is no significant correlation between these two cytokines and the development of CAL in KD.

PURPOSE: Patients with gout are similar to those with bacterial infection in terms of the nature of inflammation. Herein we compared the differences in procalcitonin (PCT) levels between these two inflammatory conditions and evaluated the ability of serum PCT to function as a clinical marker for differential diagnosis between acute gouty attack and bacterial infection. MATERIALS AND METHODS: Serum samples were obtained from 67 patients with acute gouty arthritis and 90 age-matched patients with bacterial infection. Serum PCT levels were measured with an enzyme-linked fluorescent assay. RESULTS: Serum PCT levels in patients with acute gouty arthritis were significantly lower than those in patients with bacterial infection (0.096±0.105 ng/mL vs. 4.94±13.763 ng/mL, p=0.001). However, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels showed no significant differences between the two groups. To assess the ability of PCT to discriminate between acute gouty arthritis and bacterial infection, the areas under the curves (AUCs) of serum PCT, uric acid, and CRP were 0.857 [95% confidence interval (CI), 0.798-0.917, p<0.001], 0.808 (95% CI, 0.738-0.878, p<0.001), and 0.638 (95% CI, 0.544-0.731, p=0.005), respectively. There were no significant differences in ESR and white blood cell counts between these two conditions. With a cut-off value of 0.095 ng/mL, the sums of sensitivity and specificity of PCT were the highest (81.0% and 80.6%, respectively). CONCLUSION: Serum PCT levels were significantly lower in patients with acute gouty attack than in patients with bacterial infection. Thus, serum PCT can be used as a useful serologic marker to differentiate between acute gouty arthritis and bacterial infections.

OBJECTIVETo investigate the changes in plasma gelsolin (pGSN) levels in severe burn patients with sepsis, and to evaluate the prognosis of patients when combined with other related clinical indexes.

METHODSSixty-five severe burn patients with sepsis hospitalized from June 2013 to June 2015 conforming to the study criteria were divided into death group (n=24) and survival group (n=41) according to the clinical outcome on post sepsis diagnosis day (PSD) 28. The pGSN levels of patients were determined on PSD 1, 3, 7, and 14 with double antibody sandwich enzyme-linked immunosorbent assay. The serum level of C-reactive protein (CRP), serum level of procalcitonin, lactate level of arterial blood, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and Sequential Organ Failure Assessment (SOFA) score were determined or recorded on PSD 1. Data were processed with repeated measurement analysis of variance, t test, and chi-square test. On PSD 1, the pGSN level, serum level of CRP, serum level of procalcitonin, lactate level of arterial blood, APACHE II score, and SOFA score of 65 patients were collected to screen the independent risk factors related to death with single factor and multi-factor Logistic regression analysis. Receiver operating characteristic (ROC) curves of the independent risk factors related to death were plotted to evaluate the predictive power for death in 65 patients.

RESULTS(1) The pGSN levels of patients in death group on PSD 1, 3, 7, and 14 were respectively (146±44), (85±24), (28±7), and (19±4) mg/L, obviously lower than those in survival group [(287±82), (179±51), (196±56), and (249±67) mg/L, with t values from 1.735 to 4.304, P<0.05 or P<0.01]. (2) The serum level of CRP, serum level of procalcitonin, lactate level of arterial blood, APACHE II score, and SOFA score of patients in death group on PSD 1 were respectively (56±7) mg/L, (12.54±0.82) μg/L, (2.74±0.27) mmol/L, (24.3±2.4) points, and (11.43±0.57) points, significantly higher than those in survival group [(35±4) mg/L, (2.38±0.16) μg/L, (1.83±0.12) mmol/L, (15.0±1.5) points, and (7.22±0.23) points, with t values from 1.902 to 3.883, P<0.05 or P<0.01]. (3) Multi-factor Logistic regression analysis showed that the pGSN level (odds ratio: 6.83, 95% confidence interval: 4.33-10.25, P<0.01) and APACHE II score (odds ratio: 5.27, 95% confidence interval: 2.28-9.16, P<0.01) were the independent risk factors related to death in 65 patients on PSD 1. (4) The total areas under the ROC curves of pGSN level and APACHE II score for predicting death of 65 patients on PSD 1 were respectively 0.89 and 0.86, and 142 mg/L and 21 points were respectively chosen as the optimal threshold values, with sensitivity of 87% and 83% and specificity of 86% and 89%.

CONCLUSIONSFor severe burn patients with sepsis, lowering of pGSN level and elevation of APACHE II score are obviously correlated with increase in case fatality rates. Monitoring the dynamic changes in pGSN level and APACHE II score during the early stage may be useful to predict the prognosis of severe burn patients with sepsis.

OBJECTIVETo explore the effects of oral administration of mixed enteral nutritional agent on intestinal mucosal barrier of patients with severe burn injury at early stage.

METHODSTwenty-four patients with severe burn injury admitted to our burn ward from August 2013 to September 2014, conforming to the study criteria, were divided into conventional therapy group (n = 12) and early enteral feeding group (n = 12) according to the random number table. Patients in conventional therapy group received conventional treatment immediately after admission, while those in early enteral feeding group were orally given 100 mL of a mixture of glutamine, probiotics, and prebiotics once a day besides conventional treatment for 7 days. Serum levels of diamine oxidase (DAO) and procalcitonin (PCT) and plasma level of LPS were determined by ELISA before treatment and on treatment day (TD) 1, 3, 7, 14, and 21. Wound secretion and blood samples were collected for bacterial culture within the 21 TD. The incidence of MODS within the 21 TD was observed. Data were processed with Fisher's exact test, rank sum test, analysis of variance for repeated measurement, and LSD-t test.

RESULTS(1) Serum levels of DAO in patients of early enteral feeding group on TD 7, 14, and 21 were respectively (14.9 ± 3.7), (12.4 ± 3.1), and (9.5 ± 0.7) ng/mL, which were significantly lower than those of conventional therapy group [(17.5 ± 4.0), (16.3 ± 3.3), and (13.0 ± 1.1) ng/mL, with t values from 2.913 to 15.304, P values below 0.01]. Serum levels of DAO at the other time points were close between the two groups (with t values from -0.598 to 0.139, P values above 0.05). (2) Compared with serum levels of PCT in patients of conventional therapy group [(11.7 ± 20.9) and (12.9 ± 23.9) ng/mL], those of early enteral feeding group were significantly lower on TD 7 and 14 [(2.7 ± 8.1) and (2.0 ± 5.6) ng/mL, with Z values respectively -2.919 and -2.139, P < 0.05 or P < 0.01]. Serum levels of PCT at the other time points were close between the two groups (with Z values from -1.833 to -0.346, P values above 0.05). (3) Plasma level of LPS in patients of early enteral feeding group on TD 7 was (33 ± 56) pg/mL, which was significantly lower than that of conventional therapy group [(102 ± 108) pg/mL, Z = -2.046, P < 0.05]. Plasma levels of LPS at the other time points between the two groups showed no significant difference (with Z values from -2.003~-0.526, P values above 0.05). (4) Positive results in bacterial culture of wound secretion were approximately the same between the two groups (P > 0.05). Bacterial culture of blood was positive in 7 patients of conventional therapy group and 1 patient of early enteral feeding group, showing significantly statistical difference (P < 0.05). MODS was observed in 1 patient of conventional therapy group, showing no significantly statistical difference with that of early enteral feeding group (no patient, P > 0.05).

CONCLUSIONSEarly intestinal feeding of mixed enteral nutritional agent in addition to conventional therapy can effectively promote repair of the impairment of intestinal mucosal barrier, protect integrity of intestinal mucosa, reduce damage to intestines, and alleviate inflammatory response in patients suffering from severe burn injury.

OBJECTIVETo evaluate the role of serum level of procalcitonin (PCT), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and white blood cell count (WBC) as predictors in postoperative early infectious complications with fever after posterior lumbar internal fixation (PLIF).

METHODSA retrospective study was conducted from January 2012 to January 2014. Fifty-two patients with fever in the early stage(within 10 days) after the PLIF were collected in the study. They were divided into infection group and non-infection group (group A and group B) according to the results of postoperative blood culture. There were 26 patients in group A and 32 patients in group B. The values of PCT, CRP, ESR, and WBC count were compared and analyzed between two groups.

RESULTSThe values of PCT, CRP, and ESR in group A were higher than those of group B. Meanwhile, CRP and ESR in group B were still higher than the normal range. Among the 26 patients with infections (group A), PCT was superior to CRP and ESR, had a good ability in discriminating different kinds of postoperative infections. The area under the ROC curve of serum PCT levels was the largest (CI 95% was 0.81 to 0.98) in the indexs; and ROC curve of WBC count was no statistically significant. When the cut off points of each predictors were evaluated, the higher sensitive was CRP and reached at 90.27% and the higher specific was ESR and reached at 88.50%.

CONCLUSIONFor the patients with fever at the early stage after the PLIF should be paid attention and reasonable choosing predictors are helpful to identify postoperative infection in the early stage. The CRP and ESR may be influenced by the surgery, and the PCT level is helpful to differentiate infection type.

BACKGROUND/AIMS: Serum procalcitonin (PCT) levels are low in healthy individuals but are elevated in patients with a serious bacterial infection or sepsis. In this study, we examined the ability of serum PCT concentration to diagnose infections in end-stage renal disease (ESRD) patients, and sought to determine an appropriate threshold level. METHODS: Serum PCT levels were measured in ESRD patients on antibiotic therapy for a suspected bacterial infection (ESRD infection [iESRD] group, n = 21), and compared with those of ESRD patients on hemodialysis with no sign of infection (ESRD control [cESRD] group, n = 20). RESULTS: The mean serum PCT concentration of the iESRD group was significantly higher than in the cESRD group (2.95 +/- 3.67 ng/mL vs. 0.50 +/- 0.49 ng/mL, p = 0.006), but serum PCT concentrations did not correlate with severity of infection. The optimized threshold level derived for serum PCT was 0.75 ng/mL, rather than the currently used 0.5 ng/mL; this threshold demonstrated a sensitivity and specificity of 76.2% and 80.0% for infection and 100% and 60.6% for systemic inflammatory response syndrome, respectively, compared with the cutoff of 0.5 ng/mL. CONCLUSIONS: This study suggests that serum PCT at a cutoff value of 0.75 ng/mL is an appropriate indicator of infection in ESRD patients.

OBJECTIVETo observe the protection of Qingyuan Shenghua Decoction (QSD) on multiple organs of sepsis patients after bone trauma, and to preliminarily explore its mechanism.

METHODSTotally 60 sepsis patients after bone trauma were randomly assigned to the treatment group and the control group according to random digit table, 30 in each group. All patients received routine Western medical treatment. Patients in the treatment group additionally took QSD or were nasally fed with QSD, one dose per day for 1 week. Changes of WBC, oxygenation index (PaO2/FiO2), serum creatinine (SCr), total bilirubin (TBIL), aspartate aminotransferase (AST), fibrinogen (FIB), D-dimer (DD), activated partial thromboplastin time (APTT), pro-calcitonin (PCT), C-reactive protein (CRP), heart rate (HR), mean arterial pressure (MAP), intra-abdominal pressure, scores for Acute Physiology and Chronic Health Evaluation II (APACHE II), sequential organ failure assessment (SOFA) scores were observed before treatment and on day 1, 3 and 7 after treatment.

RESULTSCompared with the control group at the same time point, MAP increased at post-treatment day 1 and 3; CRP, APTT, HR, SCr, TBIL, AST, intra-abdominal pressure at post-treatment day 3 obviously decreased in the treatment group (P < 0.05, P < 0.01). WBC, SOFA scores, PCT, CRP, APACHE II, APTT, D-D, HR, SCr, TBIL, AST and intra-abdominal pressure significantly decreased; FIB, MAP and PaO2/FiO2 obviously increased at post-treatment day 7 (P < 0.05, P < 0.01).

CONCLUSIONQSD had good protective effect on multiple organ function in sepsis patients after bone trauma, and its mechanism might be related with effectively clearing endotoxin, alleviating inflammatory reactions, and fighting against coagulation dysfunction.

OBJECTIVETo study the value of Pentraxin 3 (PTX3) in diagnosing the severity and cardiovascular function of the critically ill children. Method A total of 178 patients who were older than 28 days, with acute infection of respiratory or neurological system, excluding chronic or special disease, and admitted to the pediatric intensive care unit (PICU) of Hunan Children's Hospital from October 1, 2013 to April 30, 2014 were enrolled, including 102 male cases and 76 female cases. The ages ranged from 1 month to 13 years and 1 month, 78 of them were less than 1 year old ; 58 cases were between 1 to 3 years old; 42 cases were above 3 years old; 101 cases were diagnosed as respiratory system diseases, 77 cases had nervous system diseases. PTX3 was detected with enzyme-linked immunosorbent assay (ELISA) within 1 d after enrollment, at 3 days and 7 days, meanwhile, troponin, myocardial enzyme, brain-type natriuretic peptide (BNP), C-reactive protein (CRP), plasma calcitonin (PCT) and WBC etc. Were measured. According to the plasma PTX3 value which were measured within 24 h after enrollment the patients were divided into three groups: mildly elevated group (< 44 µg/L) 41 cases; moderately elevated group (44 - < 132 µg/L) in 66 cases; severely elevated group 71 cases (132 µg/L or higher). Those 178 patients were divided into 3 groups according to the degree of infection: non-sepsis group (78 cases), sepsis group (70 cases), severe sepsis group (30 cases), and in each group, those with heart failure were respectively 19 cases, 28 cases, 17 cases. Analysis of the plasma PTX3 expression changes in different clinical manifestations, different condition, different degrees of organ damages and prognosis for the patient. The continuous variables were analyzed with t-test, F-test, H-test, the categorical variables were analyzed with Chi-square test, and the correlation analysis was performed to calculate Pearson coefficients.

RESULTThe PTX3 value measured within 24 h after enrollment increased with the degree of infection (50. 4(35. 2,70. 4) µg/L; 175. 8 (99. 6, 309. 9) µg/L;419. 9 (168. 3, 468. 6) µg/L; H = 88. 345, P = 0. 000). PTX3 level gradually declined, while in severe sepsis group decreased slowly (P <0. 05); the area under the ROC curve of Plasma PTX3 was larger than that of other inflammatory markers such as CRP and PCT, white blood cells and neutrophils in the diagnosis of sepsis; while the former three are PTX3, PCT and CRP (the sensitivity and specificity respectively were 0. 77, 0. 68; 0. 66, 0. 6; 0. 47, 0. 55); the PTX3 value of the severely elevated group was significantly higher than those of the mildly and moderately elevated groups (P <0. 05). The proportion of having 3 or more organs failure increased as the PTX3 rising among the groups of mildly elevated group, moderately elevated group and severely elevated group (1(2. 4%), 4(6. 1%), 14(19. 7%) χ2 =16. 16,P = 0. 000); and in each group, the proportion of having good and poor prognosis for these three groups were different (33 (80.5%) and 8 (19. 5%), 35 (53%) and 31 (47%), 28 (39.4%) and 43 (60.6%), χ = 17. 663, P = 0. 000). The K-M curve for these three groups had statistically significant difference (χ2 = 7. 086, P = 0. 029). Those with heart failure had higher PTX3 value than those in non-heart failure at the same degree of infection. PTX3 value increased with myocardial enzyme (troponin, creatine kinase isoenzyme, BNP) levels. In the diagnosis of heart failure, the area under the ROC curve were respectively PTX3 0. 824; BNP 0. 772; CM-KB 0. 643; CNTIO. 671, the sensitivity and specificity were PTX3 0. 8, 0. 58; CK-MB 0. 56,0. 79; CTNI 0. 60,0. 69; BNP 0. 73, 0. 58. In terms of predicting the prognosis of sepsis with heart failure complications, the PTX3 value's area under ROC curve was larger than that of BNP (respectively 0. 844, 0. 472).

CONCLUSIONThe PTX3 is an objective biochemical marker in diagnosis of sepsis; it is helpful in assessment of severity and prognosis of sepsis; it also has a certain clinical value in the assessment of sepsis cardiovascular function damage.

OBJECTIVETo explore the risk factors for coronary artery lesions (CAL) secondary to Kawasaki disease (KD) in children.

METHODSThe medical data of 895 children with KD were retrospectively reviewed. The patients were classified into two groups according to the presence of CAL: CAL (n=284) and control (n=611). The clinical and laboratory indices were compared between the two groups. The risk factors for the development of CAL in children with KD were identified by multiple logistic regression analysis.

RESULTSMale gender (OR=1.712), occurrence of non-CAL complications (OR=2.028), atypical KD (OR=3.655), intravenous immunoglobulin (IVIG) resistance (OR=2.912), more than 5 days of fever duration before IVIG treatment (OR=1.350), and increased serum procalcitonin (PCT) level (OR=1.068) were the independent risk factors for the development of CAL in children with KD (P<0.05), whereas increased serum albumin (Alb) level was a protective factor (OR=0.931, P<0.05). The areas under the receiver operating characteristic curve of serum PCT and ALB for prediction of the development of CAL in children with KD were 0.631 and 0.558, respectively.

CONCLUSIONSMale gender, atypical KD, occurrence of other non-CAL complications, long duration of fever and IVIG resistance are associated with an increased risk for CAL in children with KD. Serum PCT and ALB have little value in the prediction of CAL in children with KD.

OBJECTIVETo study the correlation between serum procalcitonin (PCT) level and severity of infant muggy syndrome (IMS) and the predictive value of PCT in the development of multiple organ dysfunction syndrome (MODS) in children with IMS.

METHODSFifty children with IMS were classified into two groups according to the presence of MODS: MODS (n=29) and non-MODS (n=21). According to a 30-day follow-up result, they were classified into survival (n=36) and deceased groups (n=14). Vital signs, routine biological measurements (arterial blood gas, blood routine, CRP, liver and kidney functions, myocardial enzyme and so on) and the disease severity evaluated by the Pediatric Critical Illness Score (PCIS) within 24 hours of admission were recorded. Serum levels were measured using the semi-quantitative PCT-Q test within 24 hours of admission.

RESULTSForty-seven children (94%) had elevated serum PCT levels (≥ 0.5 ng/mL) at admission. There were lower PCIS scores, higher rates of MODS and higher levels of serum PCT in deceased patients than survivors (P<0.05). There was a significant negative correlation between serum PCT levels and PCIS scores (r=-0.84, P<0.05). Serum PCT levels in the MODS group were significantly higher than in the non-MODS group (P<0.01). Receiver operating characteristic curve showed that, if the cut-off point of serum PCT level was 10.6 ng/mL, the sensitivity and specificity of PCT were 79.3% and 90.5% respectively, in predicting MODS, with the area under the curve of 0.924 ( P<0.01).

CONCLUSIONSSerum PCT level at admission is correlated with the severity of IMS and it may be an early predictive marker of MODS.
