Multicenter clinical epidemiologic study for treatment of severe hand-foot-and mouth disease / 中华实用儿科临床杂志

ABSTRACT

Objective To investigate the treatment,outcomes and disease burden of severe hand-foot-and mouth diseases(HFMD),and to evaluate the compliance to the 2011 guideline for treatment in regions with a high in-cidence of HFMD.Methods A collaborative study group was established including Children's Hospital of Fudan Uni-versity,Jiangxi Provincial Children's Hospital,Anhui Provincial Children's Hospital,Linyi People's Hospital and the Second People's Hospital of Fuyang City.Clinical manifestation,treatment,prognosis and other data of severe HFMD pa-tients were prospectively collected by filling out a survey form in real time from April 2014 to October 2016. Results Two hundred and twenty-six severe HFMD cases were collected during the research time,including 114 ca-ses in stage 2,75 cases in stage 3,and 37 cases in stage 4.Two hundred and twenty-one cases(97.8%)were given mannitol,with a mortality of 6.2%;91 cases(40.3%)were given mannitol and glycerol fructose,with a mortality of 3.3%;the combined use of mannitol and glycerol fructose might have a better result than the single use of mannitol. One hundred and ninety-eight cases(87.6%)were given intravenous immunoglobulin(IVIG).One hundred and ninety cases(84.1%)were given antiviral drugs.One hundred and forty-five cases(64.2%)were given hormone therapy,and the use of hormone could reduce temperature,but did not reduce the mortality.One hundred and fifty cases (66.4%)needed vasoactive agent,including milrinone,dobutamine,phentolamine and sodium nitroprusside. The vasoactive agent use in stage 3 and 4 were 88.0%(66/75 cases)and 91.9%(34/37 cases),respectively.Sixty-nine cases(30.5%)received continuous positive airway pressure(CPAP),91 cases(40.3%)with mechanical ventila-tion,peak inspiratory pressure(PIP)≥20 cmH2O(1 cmH2O=0.098 kPa)accounted for 61.6%(53/86 cases),po-sitive end-expiratory pressure(PEEP)≥10 cmH2O accounted for 36.3%(33/91 cases).The mean mechanical ven-tilation time was(125.9 ± 101.8)h.Eleven cases(4.86%)died or died after giving up treatment,in which the mortality in stage 3 was 6.7%(5/75 cases),and the mortality in stage 4 was 16.2%(6/37 cases).The death causes were respiratory failure,pulmonary hemorrhage,and circulatory failure. The average time from onset to death was (5.91 ± 5.26)(1-15)d.Length of stay in hospital was(9.18 ± 5.16)(1-37)d in which length of stay in hospi-tal in stage 3 and 4 were(11.3 ± 6.35)d,(11.4 ± 6.62)d,respectively,which were significantly longer than that in stage 2[(7.50 ± 3.04)d],and the difference was statistically significant(P <0.05). The cost was(19 136 ± 12 556)CNY,of which the cost in stage 3 and 4 was(23 121 ± 13 846)CNY,(29 849 ± 16 015)CNY,respectively, which were significantly higher than that in stage 2[(12 961 ± 4 272)CNY],and the difference was statistically sig-nificant(P<0.05). Multivariate analysis found that respiratory rhythm abnormality,capillary refill time more than 3 seconds were risk factors for the deaths in the severe HFMD.Conclusion The 2011 edition of guidelines for treat-ment of children with severe HFMD was well executed.Hormone,IVIG,antiviral drugs did not significantly reduce the mortality of severe HFMD in children.
