Study on the level of D-lactic acid and the intestinal barrier function of children with hand, foot and mouth disease of different intestinal virus infection / 中国医师进修杂志

ABSTRACT

Objective To explore the variation of serum D-lactic acid levels and the correlation between different intestinal viral and intestinal barrier function in children with hand, foot and mouth disease (HFMD). Methods The stools of 129 children with HFMD were collected and were detected by reverse transcription polymerase chain reaction. The children were divided into four groups according the fecal pathogens detection:enterovirus 71 (EV71) positive group, Coxsackie virus A16 (CoxA16) positive group, other intestinal virus positive group (EA positive group), and no intestinal virus group (EA negative group). Two ml venous blood and separation serum was collected in each group of children, and the level of serum D-lactic acid was detected further. Results There were 20 cases of other Coxsackie virus, and they were not grouped. Fifty-seven patients were in EV71 positive group, 26 patients were in CoxA16 positive group, 10 patients were in EA positive group, and 16 patients were in EA negative group. The level of D- lactic acid in four groups was 26.28 (17.02- 58.01), 14.43 (8.93- 20.66), 10.66 (6.64- 18.51) and 14.07 (11.83- 27.46) mg/L. The results of rank test showed the level of D-lactic in EV71 positive group was significantly higher than that in EA positive group (Z=-2.432, P=0.015) and EA negative group (Z=-3.092, P=0.002). Conclusions D-lactic acid level increases significantly in EV71 infection children and suggests that the illness is more serious and the intestinal barrier is damaged. Doctors should pay more attention to monitor and protect gastrointestinal function of children with HFMD.
