To compare the clinical effect of different doses of methylprednisolone in the treatment of severe hand foot mouth disease in children / 中国生化药物杂志

Objective To compare the clinical effect of different doses of methylprednisolone in the treatment of children with severe hand foot mouth disease research and analysis. Methods 100 patients in our hospital from January 2014 to August 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The control group were treated with small doses of methylprednisolone, 2 mg/ (kg?d), intravenous injection. The experimental group was treated with large dose of methylprednisolone, 10～15 mg/(kg?d) intravenous infusion. The therapeutic effects of the experimental group and the control group were compared and analyzed. Results after the corresponding treatment, the number of adverse reactions in the experimental group was 31, the adverse reaction rate was 62.0％, and the adverse reaction rate in the control group was 60.0％. There was no significant difference in the incidence of adverse reactions between the two groups. The upper respiratory rate and critical illness in the experimental group were 26.0％ and 32.0％, significantly lower than that of the control group (P<0.05). The average remission time of the patients in the experimental group was (2.19±1.01) days. The symptomatic remission time in the control group was (4.19±1.89) days. The remission time of the control group was significantly longer than that of the experimental group, with statistical difference (P<0.05). Conclusion The short term large dose of methylprednisolone in treatment of children with severe HFMD clinical effect is ideal, can be reduced to critical illness rate, less symptom remission time, with the further promotion of the clinical significance.

The study of clinical applying continuous hemofiltration in children severe hand-foot-and-mouth disease with cardiopulmonary failure / 中国小儿急救医学

Objective To analyze the clinical value of continuous veno-venous hemofiltration (CVVH) treatment in children with severe hand-foot-and-mouth disease(HFMD) complicated with cardiopulmonary failure,via the prognostic comparison of the general comprehensive treatment and CVVH add-on treatment.Methods Fifty-one cases of severe HFMD with cardiopulmonary failure were divided into a CVVH group (n =19) and a control group(n =32) based on whether CVVH add-on or not.Their physiological and biochemical indicators were recorded and pediatric critical illness score (PCIS) and pediatric risk of mortality score (PRISM Ⅲ) were calculated within 24 hours,when they were diagnosed with neurogenic pulmonary edema (NPE)/pulmonary hemorrhage.Both groups were treated with endotracheal intubation,mechanical ventilation with high PEEP,corticosteroids,ulinastatin,actively lowering the intracranial pressure,fluid resuscitation,milrinone,dopamine and other vasoactive drugs,high-dose intravenous gamma globulin,the CVVH group were added with CVVH treatment(duration ＞ 12 h).Prognosis difference of CVVH add-on treatment after diagnosed with NPE/pulmonary hemorrhage by tracking indicators of the third day.Survival analysis between two groups were compared by 3-day survival rates,7-day survival rates,28-day survival rates and the finally survival rates.Results (1) The overall conditions of two groups were comparable when diagnosed with NPE/pulmonary hemorrhage.PCIS,PRISM Ⅲ,WBC counting,lactic acid,micro-blood sugar,myocardial enzymes and liver enzymes showed no significant difference between two groups.Three days after treatment,WBC and lactic acid decreased,but there was no significant difference (P ＞ 0.05),the remaining indicators had significantly improved in the CVVH group than those in the control group (P ＜ 0.05).(2) The 3-day survival rate,7-day survival rate,28-day survival rate and the finally survival rates in control group and CVVH group were 40.63 ％ vs.84.21％,37.50％ vs.73.68％,25.00％ vs.63.16％,18.75％vs.52.63％,the survival rate in CVVH group were significantly higher(P ＜0.05).(3)The survival curve indicated that the survival time of CVVH group was significantly longer than that of the control group,the median survival time were 17 d and 2 d,respectively,and the difference was statistically significant (P ＜ 0.05).(4)In the CVVH group,15 cases received CVVH after diagnosed with NPE/pulmonary hemorrhage within 12 hours,of which 10 cases(66.67％) ultimately survived,while the other 4 cases received CVVH after 12 h were all end to death,the difference was statistically significant(P ＜ 0.05).Further analysis of the impact of the timing of blood purification on the prognosis of children showed that the mortality rates of children received CVVH within 6 hours,6 to 12 hours,after 12 hours of diagnosis of NPE/pulmonary hemorrhage,were 2/8,3/7,4/4,respectively.Conclusion Continuous hemofiltration can significantly improve the prognosis of children with severe HFMD,and may be preferable to perform in early stage.

Effect of mouse nerve growth factor on humoral immunity in children with severe hand foot mouth disease / 中国生化药物杂志

Objective To investigate the effect of mouse nerve growth factor on humoral immunity in children with severe hand foot mouth disease. Methods 92 patients with severe hand foot mouth disease were selected from June 2010 to September 2012 in the hospital, and randomly divided into two groups.The indexes of blood cell analysis, humoral immunity, cytokines and T lymphocyte subsets were compared after treatment.Results After treatment, compared with control group, the numeration white blood cell, neutrophil and lymphocyte of observation group were lower (P<0.05), IgM, IgG and IgA were higher (P<0.05), IL-1, IL-6 and IL-10 were lower (P<0.05), CD4 +and CD8 +were higher (P<0.05).Conclusion Mouse nerve growth factor can significantly improve the each index of humoral immunity cytokines and T lymphocyte subsets level in children with hand foot mouth disease, which has the great significance in clinical.

Use of glucocorticoid in severe hand-foot-mouth disease and the therapeutic effects of different dose of glucocorticoid in Henan and Sichuan Province / 中华实用儿科临床杂志

Objective To investigate the use of glucocorticoid in severe hand-foot-mouth disease in Henan and Sichuan Province and to compare the therapeutic effects of different dose of glucocorticoid.Methods In this multicenter retrospective study,320 cases of severe hand-foot-mouth disease,which were randomly sampled from Jan.to May 2011 in Henan and Sichuan Province were collected.The use of intravenous glucocorticoid was calculated.Accor-ding to the dose of corticosteroids which had been used,these cases were divided into 3 groups:the non-corticosteroids group,the low-dose group and the high-dose group.The cure rate,febrile duration,nervous system involvement duration,time of staying in hospital,vital signs and serum glucose in 3 groups were compared.Results Patients who used intravenous glucocorticoid accounted for 90.9％ (291/320 cases),and only 29 patients had not used (9.1％).The cure rate among 3 groups were not significantly different(P ＞0.05).In the low-dose group and the high-dose group,the nervous system involvement duration,the febrile duration and time of staying in hospital were longer than those in the non-corticosteroids group (all P ＜ 0.05).Comparing the blood pressure among 3 groups on the first day and the third day of hospitalization,the diastolic blood pressure in the high-dose group was much higher than that in other 2 groups on the third day of hospitalization(all P ＜ 0.05).Conclusions Glucocorticoid is generally used in severe hand-foot-mouth disease in Henan and Sichuan Province.The high-dose glucocorticoid is more often used in the situation that fever,nervous system involvement are not relieved.Glucocorticoid can never improve the cure rate in patients with severe hand-foot-mouth disease or shorten the course,relieve clinical symptoms.The therapeutic effects of glucocorticoid in severe hand-footmouth disease are not confirmed.The therapy of high-dose glucocorticoid may increase medicinal side effects.

Clinical features of severe hand-foot-mouth disease combined with encephalitis / 中国小儿急救医学

Objective To analyze the clinical features of severe hand-foot-mouth disease (HFMD)combined with encephalitis.Methods The cases with HFMD in our hospital from September 2009 to September 2010 were divided into two groups including the ordinary case group(n =235) and the encephalitis group (n =88).Clinical manifestations were analysed between the two groups.Results There were significant differences in number of oral ulcers,degree and duration of fever between two groups (P ＜ 0.05).Eighty percent cases of the ordinary group had multiple or dense herpes or ulcers,which was more than that of the encephalitis group.But there were no significant differences in WBC and its classification in peripheral blood between two groups (P ＞ 0.05).There were obvious differences in CK,CK-MB,AST,GLU of blood between two groups (P ＜ 0.05).The contents of protein,glucose and chloride in cerebrospinal fluid have no differences between two groups (P ＞ 0.05),besides the cell count.The cell count in cerebrospinal fluid of cases with enterovirus infected encephalitis was significantly higher than those with CoxA16 infection(P ＜ 0.05).Conclusion The patients with few rash,less oral herpes,ulcers or high levels of CK,CK-MB,GLU should be closely observed to vigilant merger encephalitis.The cases with severe H-FMD have middle or high fever and duration of fever are more than 4 days.The increased cell count in cerebrospinal fluid may imply encephalitis with enterovirus 71 infection.

Risk factors of neurogenic pulmonary edema in the patients with severe hand, foot and mouth disease / 中国小儿急救医学

Objective To understand the risk factors of neurogenic pulmonary edema in the patients with severe hand foot and mouth disease(HFMD). Methods According to neurogenic pulmonary edema or not ,79 patients with severe HFMD were divided into two groups. The difference was analyzed on the clinical symptoms, signs,the outcomes of laboratory and electroencephalogram (EEG) examination between the two groups. Then the risk factors of neurogenic pulmonary edema was analyzed by logistic regression analysis.Results There were significant differences of the EV71 infection rate,high body temperature,myoclonia,limb weakness,the disability of eyeball regulation,tachycardia, hypertension or hypotension, the extension of capillary filling time, leucocytosist, creatine kinase isoenzyme, hyperglycaemia between two groups. However, there were no significant differences of fever, fever time, vomiting, somnolence, convulsion, limb tremor, c-reactive protein and EEG between two groups. Tachycardia, hypertension or hypotension, hyperglycaemia were significant risk factors for neurogenic pulmonary edema by logistic regression analysis. And hyperglycaemia was the most significant prognostic factor(odd ratio 27. 075, P = 0. 000 2). Conclusion Tachycardia, hypertension or hypotension,hyperglycaemia are the significant risk factors for neurogenic pulmonary edema. It is especially important for hyperglycaemia to predict neurogenic pulmonary edema.

Clinical features and treatment of 147 cases with severe hand, foot and mouth disease receiving mechanical ventilation / 中国小儿急救医学

Objective To summarize the clinical features,diagnostic and treatment experience of severe hand,foot and mouth disease(HFMD) cases receiving mechanical ventilation from Jan 1 to Sep 6,2009 in our hospital and provide reference for reducing the occurrence of neurogenic pulmonary edema(NPE) and mortality. Methods 147 severe HFMD who received mechanical ventilation were analyzed by a retrospective investigation. Results 85.0% children were less than 3 years old and 100% patients had a fever. The mechanical ventilation occurred within 1 to 4 days after fever (3.06 ± 1. 02) d. Neurological complications presented as bad spirit,easy surprised, involuntary movement of the extremities and lethargy. Respiratory system complication presented as polypnea, hypepnea and irregular rhythm. Circulatory system complication presented as heart rate increase or decrease, hypertension or hypotension, piebald skin and low limb temperature.Some of the children had high white blood cell counting,glucose and lactic acid of the blood. The EV71-PCR positive rate was 34. 7% for throat swabs,and 42. 2% for anal swabs. Chest X-ray presented as increased broncho vascular shadows, exudation or nonapparent abnormality. Only three children were dead, fatality rate was 2. 0%. Conclusion The HFMD cases in this outbreak are relatively more serious,and change rapidly. It's difficult to treat as soon as NPE appeared,and it has high fatality rate. Early recognition of critical patients,timely giving mechanical ventilation,and the comprehensive treatment can reduce NPE incidence and the mortality.
