ABSTRACT
@#Abstract: Objective To observe the expression of peripheral blood stimulating molecules CD80 and CD86 in children with severe hand, foot, and mouth disease (HFMD), and to analyze the relationship between them and the therapeutic effects of children. Methods The clinical data of 252 children with severe HFMD treated in Wuhan Hospital of Traditional Chinese Medicine from March 2017 to March 2021 were collected retrospectively. All children were treated with standardized treatment and the therapeutic effects was evaluated. The baseline data and laboratory test results of children were recorded, and the positive rates of CD80 and CD86 cells in peripheral blood were detected by flow cytometry. Logistic regression was used to analyze the relationship between the above indexes and the therapeutic effects of children. The receiver operating curve (ROC) was drawn to evaluate the value of the above indicators in predicting the therapeutic effects of children. Results After standardized treatment, 48 children were ineffective, and 204 children were effective; the levels of serum CD80 [(2.28±0.84)% vs (2.12±0.33 )%] and CD86 [(3.35±0.96)% vs (2.23±0.41)%] in children were significantly lower than those at admission (t=2.851, 16.991; P<0.05). The levels of blood lactic acid, serum C-reactive protein (CRP), matrix metalloproteinase-9 (MMP-9), CD80 and CD86 at admission in the ineffective group were significantly higher than those of the effective group (P<0.05). Logistic regression analysis showed that the overexpression of serum CRP (OR=10.929), MMP-9 (OR=1.926), CD80 (OR=3.943) and CD86 (OR=1.947) at admission might be the risk factors of ineffective (all P<0.05). The results of the goodness of fit test for the model showed that, the goodness of fit was high (χ2=6.245, P=0.620); the model collinearity results showed that the variance inflation factors (VIF) values of each variable were <2, and there was no collinearity among the main indicators; the results of the individual independence test for the model showed that Durbin-Watson statistics (D-W)=0.279 and there was poor mutual independence among main indicators. ROC curve analysis showed that the area under the curve(AUC) of serum CD80 at admission in predicting the therapeutic effects of children was 0.762, the cut-off value was 2.390%, and the specificity, sensitivity and Youden index were 0.598, 0792 and 0.390 respectively; the AUC predicted by CD86 was 0.739, the cut-off value was 3.280%, and the specificity, sensitivity and Youden index were 0.510, 0.896 and 0.406 respectively; the AUC by combined prediction was 0.823, and the specificity, sensitivity and Youden index were 0.696, 0.833 and 0.529 respectively. Conclusions Peripheral blood stimulating molecules CD80 and CD86 are involved in the progression of HFMD. Their overexpression may suggest a high risk of treatment ineffectiveness in children with severe HFMD. Early dynamic monitoring of the expression of serum CD80 and CD86 has a certain predictive value for the therapeutic effect of children.
ABSTRACT
Objective:To explore the clinical significance of serum Chromogranin A (CGA) level in predicting the prognosis of children with severe hand, foot, and mouth disease (HFMD) and complicating neurogenic pulmonary edema (NPE).Methods:A total of 162 patients with HFMD admitted in our hospital from January 2017 to December 2019 were enrolled in the study; and 40 age-matched healthy children were selected as controls. According to the disease severity and complication the patients were divided into three groups: mild group ( n=88), severe without NPE group ( n=46) and severe with NPE group ( n=28). In 72 severe HFMD patients 16 cases died (fatal group) and 56 cases survived (survival group) within 28 days of hospitalization. The serum CGA, LAC, GLU, WBC, PCT, IL-6, cTnT were measured in all subjects. SPSS 23.0 software was used for data analysis, and the receiver operating characteristic (ROC) curve was used to evaluate the various indicators for predicting the prognosis of severe HFMD combined with NPE. Results:The serum CGA, GLU, LAC, IL-6 and cTnT levels in severe HFMD group with NPE significantly higher than those in the other three group ( H=61.554, 79.031, 86.994, 36.477, 75.021, all P<0.05 ). The serum CGA, LAC, GLU and IL-6 levels in the fatal group were significantly higher than those in survival group ( Z=-6.094, -4.621, -4.283, -5.504, all P<0.05). There was no significant difference in the levels of WBC, PCT and cTnT between the survival group and the fatal group ( P>0.05). The area under the receiver operating curve (AUC) of serum CGA was 0.890 (95% CI: 0.833-0.947) for predicting the prognosis of patients and the best cut-off value was 120.59 μg/L. Conclusion:The detection of serum CGA levels may be beneficial for the early diagnosis of severe HFMD with NPE, and can be used as one of the predictors of death from severe HFMD.
ABSTRACT
OBJECTIVE@#To observe the effect of acupuncture combined with conventional symptomatic and supportive treatments on swallowing function and nutritional status in children with severe hand foot and mouth disease complicated with dysphagia.@*METHODS@#A total of 68 children with severe hand foot and mouth disease complicated with dysphagia were randomized into an observation group and a control group, 34 cases in each one. Symptomatic and supportive treatments such as lowering temperature, tranquilizing and mechanical ventilation were adopted in the control group. On the basis of the treatments in the control group, acupuncture was applied at Lianquan (CV 23), Jialianquan (Extra), cervical Jiaji (EX-B 2), Fengfu (GV 16), Fengchi (GB 20), Yamen (GV 15), scalp motor and sensory areas in the observation group, once a day, 6 times a week, one month as a course and totally 3 courses were required. Time spent on restoring swallowing function was observed in both groups. Besides, score of dysphagia disorder survey (DDS) and nutritional status were evaluated before and after treatment, and the clinical effects were compared.@*RESULTS@#The total effective rate was 91.2% (31/34) in the observation group, which was superior to 73.5% (25/34) in the control group (<0.05). The time of restoring swallowing function in the observation group was advanced than the control group (<0.05). Compared before treatment, the DDS scores after treatment were decreased in both groups, and the reduction in the observation group was larger than the control group (all <0.05). After the treatment, the normal rate of nutritional status was 61.8% (21/34) in the observation group, which was superior to 32.4% (11/34) in the control group (<0.05).@*CONCLUSION@#On the basis of conventional treatment, acupuncture can effectively treat the severe hand foot and mouth disease complicated with dysphagia, improve the swallowing function and nutritional status.

ABSTRACT
Hand,foot and mouth disease is a common acute fever and rash disease in pediatrics,which seriously affects children's health.It is still an important public health problem for children in China.Now,a comprehensive review of early identification and standardized diagnosis and treatment of severe cases,especially critical hand,foot and mouth disease is performed,in order to improve the success rate of severe hand,foot and mouth disease.
ABSTRACT
The severe hand,foot and mouth disease(HFMD) caused by Enterovirus 71 (EV71) has become a serious threat to children's health.It is an important issues which need to be faced and resolved by pediatrician and disease prevention and control system,especially pediatric critical care specialist.The pathogenesis of severe HFMD caused by EV71 has not been clearly defined so far,and the clinical treatmnent is controversial.So,to further explore the mechanism of EV71 infection in severe HFMD and explore new effective prevention and control methods,have important significance in reducing the mortality and improve the quality of life of patients with severe HFMD.
ABSTRACT
Objective To comment the severity of severe hand,foot and mouth disease(HFMD)by pediatric risk of mortality score(PRISM),and assess the performance of PRISM in predicting mortality or complication probability in HFMD.Methods Four hundred and twenty-four severe HFMD pediatric patients were recruited in the study from 1th Jan 2010 to 31th June 2013.Information on the outcome and the varia-bles required to calculate PRISM score were collected.The logistic regression model developed in the learning sample was evaluated in the test sample by calculating the area under the receiver operating characteristic (ROC)curve to assess discrimination pneumorrhagia and death.Calibration across deciles of risk was evalua-ted using the Hosmer-Lemeshow goodness-of-fit χ2 test.Results The area under the ROC curve were 0.87 (95%CI 0.80~0.94 )for PRISM in predicting pneumorrhagia probability.The area under the ROC curve were 0.87(95%CI 0.80~0.95)for PRISM in predicting mortality probability.The PRISM in observed and expected pneumorrhagia did not demonstrate good calibration at ten mortality risk intervals (χ2 =36.66, P<0.001 ).The PRISM in observed and expected mortality did not demonstrate good calibration at ten mortali-ty risk intervals(χ2 =41.11,P<0.001).Conclusion The PRISM score is demonstrated good discrimination of pneumorrhagia and death in HFMD pediatric patients,but the performance of calibration is not good.
ABSTRACT
Objective To explore clinical therapeutic effect of cattle encephalon glycoside and ignotin (EGI)on adjunc-tive therapy of severe hand-foot-and-mouth disease (HFMD).Methods 94 children with severe HFMD in a hospital were selected and divided into two groups according to the parity of patients’admission numbers,46 children in control group were given conventional therapy;48 children in trial group were given EGI adjunctive therapy based on conventional thera-py,therapeutic effect of two groups was compared.Results The total therapeutic effective rate in trial group was signifi-cantly higher than that of control group (95.83% vs 76.09%,χ2 =16.81,P 0.05);after therapy,neurological function score in trial group was significantly lower than control group ([4.07±0.13]vs [5.59±0.18],χ2 =18.19,P <0.05).The recovery time of temperature,heart rate,blood pressure,and breathing,as well as length of stay in hospital in trial group were all significantly shorter than control group(P <0.05);incidence of complications in trial group was lower than control group (4.17%[n=2]vs 21.74%[n=10],χ2 =10.08,P <0.001 ).The proportion of turning into critically ill cases in trial group was significantly lower than control group (2.08% [n = 1 ]vs 13.04% [n = 6 ],χ2 = 8.94,P < 0.001 ). Conclusion EGI has remarkable efficacy in adjunctive therapy of severe HFMD,which can effectively improve clinical symptoms,and is worthy to be popularized and applied.
ABSTRACT
ObjectiveTo explore the clinical feature of severe hand, foot and mouth disease (HFMD) in pediatric patients, and to observe the hemodynamic changes in those with acute pulmonary edema.Methods A prospective observation study was conducted. Thirty-five severe HFMD pediatric patients with acute pulmonary edema admitted to the intensive care unit (ICU) and Department of Pediatric of First People's Hospital of Foshan from May 2008 to September 2014 were enrolled. The clinical features were thoroughly investigated. Hemodynamic data were monitored by pulse-indicated continuous cardiac output (PiCCO) in 5 cases, and the changes in PiCCO parameters were observed at ICU admission (0 hour), and 24, 48, 96 hours after treatment.Results Thirty-five patients who met the diagnostic standard of severe HFMD were enrolled, including 22 male and 13 female, aged from 7 months to 4 years. Six patients were younger than 1 year, 13 1-2 years, 12 2-3 years, and 4 patients 3-4 years old. The most common time of occurrence of pulmonary edema was 3-4 days after the onset of the disease. Fever and central nervous system symptoms were found in all the patients, and examination of the cerebral spinal fluid (CSF) revealed non-bacterial inflammatory changes. PiCCO results showed a tendency of lowering of heart rate (HR), systemic vascular resistance index (SVRI), and extravascular lung water index (EVLWI) after the treatment, and the values obtained at 96 hours were significantly lower than those at 0 hour [HR (bpm): 119.0±14.7 vs. 200.8±19.7, SVRI (kPa·s·L-1·m-2):148.9±14.6 vs. 209.6±58.7, EVLWI (mL/kg): 10.5±1.9 vs. 34.8±10.8,P< 0.05 orP< 0.01], global end-diastolic volume index (GEDVI) was also gradually decreased without significant differences among all the time points, together with a tendency of increase in stroke volume index (SI) and cardiac index (CI). The values of the parameters at 96 hours were significantly higher than those at 0 hour [SI (mL/m2): 38.5±6.5 vs. 17.4±2.8, CI (mL·s-1·m-2): 75.0±8.0 vs. 55.5±8.5, bothP< 0.01]. Left atrium was found to be enlarged, and left ventricular systolic function decreased in two patients by cardiac ultrasonic. Four out of 35 patients died, and functional disability of extremities was found in 1 patient. Other patients were cured and discharged without any sequelae.Conclusions Severe HFMD complicated by acute pulmonary edema is a perilous condition in children, accompanied commonly by pathologic changes in central nervous system and systolic dysfunction of left ventricle. According to the results with PiCCO monitoring, HFMD patients suffering from acute pulmonary edema may be of cardiac origin in addition to neurogenic origin.

Objective To investigate the role of tracheotomy in children with severe hand foot and mouth disease.Methods Eight children with severe hand foot and mouth disease collected from July 2009 to August 2011 in PICU were retrospectively reviewed.Clinical manifestation and laboratory data were analyzed and followed up.Results Eight patients were enterovirus 71 (EV71) positive.Hormones,intravenous immune globulin,mechanical ventilation and vasodilators had been administered in patients with cardiopulmonary failure.They had severe neurologic sequelae,requiring prolonged intubation.MRI imaging of 7 cases showed abnormal brainstem,pons and medulla oblongata,1 case showed swelling of brain tissue.A total of 8 patients underwent a tracheotomy in mean (25.63 ± 8.86) d.The older was 22 months,the younger was 8 months and the mean age was (13.13 ±4.22) months.Four cases died,the other survived.Two cases were successfully decannulation,the other two were still in the tracheotomy.Conclusion Tracheostomy play an active role in reducing airway resistance,clearing airway secretions,providing the opportunity for subsequent rehabilitation.Eight patients were followed up for three years,neurological sequelae could not be restored.Four cases repeatedly suffer from pneumonia,atelectasis,leading to a serious decline in quality of life.
ABSTRACT
Objective To investigate the value of brainstem auditory evoked potential (BAEP) in early diagnosis of severe hand,foot and mouth disease (HFMD) with the nervous system damage.Methods BAEP was performed in 297 cases with HFMD.The patients were divided into 4 groups by the HFMD clinical classification and their ages.Group A included the general cases who were younger than three years (n =80).Group B included the severe cases who were younger than three years(n =94).Group C included the general cases who were three years or older(n =38).Group D included the severe cases who were three years or older(n =85).The electroencephalogram (EEG) and MRI results of patients in the groups were retrospectively studied and the results were compared with that of BAEP.Results (1) The BAEP abnormal rate of group B (18/94,19.15％)was higher than that of group A (3/80,3.75％),and the BAEP abnormal rate of group D (13/85,15.29％) was higher than that of group C (1/38,2.63％) (P ＜ 0.05).(2) The EEG abnormal rate in group B was low(2/94,2.13％) and there was no case with abnormal EEG in group A.(3) The EEG abnormal rate of group D (49/85,57.65％) was higher than that of group C (6/38,15.79％) (P ＜0.05),and higher than the BAEP abnormal rate of group D.(4) The MRI abnormal rate of group B (9/94,9.57％) was higher than that of group A (1/80,1.25％) (P ＜ 0.05),and the MRI abnormal rate of group D (9/85,10.59％)was higher than that of group C (0).(5) The BAEP abnormal rate of the children with severe HFMD (31/179,17.32％) was higher than the MRI abnormal rate (18/179,10.06％) (P ＜0.05).Conclusion BAEP has clinical significance for early diagnosis of severe HFMD with nervous system damage,and can provide objective basis for the diagnosis.
ABSTRACT
Severe hand foot and mouth disease can lead to death when accompanied by neurogenic pulmonary edema. Early identifying involvement of central nervous system, focusing on the evidences of excited sympathetic nerve tension and high risks of neurogenic pulmonary edema, monitoring respiratory rate,dyspnea, cyanosis, fine and medium rales in lungs are critical to prognosis. Managing fluid loading strictly, decreasing intracranial hypertension, supporting actively respiratory function and strengthening airway management are key points for the treatment of neurogenic pulmonary edema.
ABSTRACT
Objective To analyse the etiology and clinical characteristics of 26 critically ill children with severe hand foot and mouth disease (HFMD) of Shanxi province in 2010.Methods We retrospectively analysed the clinical data of 26 children with severe HFMD from Mar to Sep 2010.Nucleic acid of enterovirus 71 ( EV71 ) and Coxsackie virus A 16 ( CoxA16) were detected in 20 out of 26 children with HFMD by reversed real time polymerase chain reaction (rRT-PCR),and the whole VP1 gene of EV71 deriving from 6 different areas of Shanxi province was amplified,sequenced,and compared with strains from other areas in china.Results EV71 nucleic acid were positive in 18 out of 20 children,while the other two were negative for EV71 and CoxAl6.Among all the critical cases,20 cases (76.9％) occurred in Weinan area,four in Xianyang area,and two in Xi'an urban area.Compared with those of Fuyang Anhui,Hong Kong China,Guangzhou,Shenzhen,Shandong,Beijing,the homology of the whole VP1 gene sequence from 6 strains of Shanxi area was 96％ ～ 100％.Most of the critical children were under 3-year-old,and the incidence rate of male children was higher than that of female children.All affected children had persisted fever,poor energy,hyperarousal,hypersomnia,and limb shaking.Meanwhile their peripheral blood leukocytes,C-reactive protein and blood glucose were markedly increased,but renal injuries were rare.Eighteen children clinically recovered on discharge,among which 2 cases had sequelae of limb activity obstacle,and 8 cases died.Conclusion Weinan is the area with the highest incidence rate of critical HFMD cases in Shanxi Province,and the major etiological organism is EV71,which is highly homologous to EV71 found in other regions of mainland China.As many cases are in dangerous condition,thus early identification and intervention could inhibit the disease progression,and play a key role in reducing the mortality.
ABSTRACT
Objective To explore the clinical features and risk factors of children with severe hand foot and mouth disease (HFMD).Methods The clinical data of 68 children with HFMD associated with brainstem encephalitis were analysed retrospectively from Apr to Sep 2010.Results Among the 68 cases,63cases(92.6％ ) were younger than 3 years.The major symptoms and physical signs of 68 cases included rash (68 cases,100％ ),fever (68 cases,100％ ),fatigue (68 cases,100％ ),irritability (65 cases,95.6％ ),somnolence (42 cases,61.8％ ),vomiting (28 cases,41.2％ ),limb tremor (23 cases,33.8％ ),tendon reflexe hyperactivity (60 cases,88.2％ ),tachypnea or respiratory rhythm abnormality (63 cases,92.6％ ),tachycardia (65 cases,95.6％ ),and hypertension (54 cases,79.4％ ).Twenty-five cases (36.8％,25/68 ) had leucocytosis ( ＞ 12 × 109/L ),and 19 cases ( 27.9％,19/68 ) had hyperglycaemia.X-ray appearances:patchy and pathy shadows in single or bilateral pulmonary were seen in 46 cases( 67.6％,46/68 ).Forty-eight cases were examined by MRI,eight cases displayed ischemic lesions or demyelination.Spinal cord MRI was performed in 3 cases with flaccid paralysis,which showed demyelination.The etiology indicated that 38 cases ( 55.9％,38/68 ) were infected by enterovirus 71,25 cases( 36.8％,25/68 ) were infected by other enterovirus,5 cases (7.3％,5/68) were negative.All the cases were treated by mechanical ventilation with tracheal intubation,in whom 63 cases recovered well,4 cases improved,and 1 case gave up to die.Conclusion Ages ＜ 3 years,enterovirus 71 infection,continual fever,fatigue,somnolence,irdtability,vomiting,limb tremor,tendon reflexes hyperactivity,tachypnea or respiratory rhythm abnormality,tachycardia and hypertension are the high risks of critically ill children associated with severe HFMD.To reduce the fatality rate of HFMD,it is crucial to early judge the high risk factors,and take mechanical ventilations earlier.
ABSTRACT
The virus of hand, foot and mouth disease(HFMD) damages nerve system.Brainstem is the main site and has some specific receptors.Severe HFMD has a high mortality.The main causes of death are cardiopulmonary and brain failure, so it is very important that risk factors of severe HFMD are timely judged and treated. Pulmonary edema of severe HFMD is mainly caused by neurological damage. At present, although it has still no standardized treatment scheme, the diagnosis and treatment for different stages have a significant effect.
