Clinical outcomes of immunocompromised children with acute respiratory distress syndrome / 中华急诊医学杂志

Objective To investigate the clinical outcomes of immunocompromised (IC) children with pediatric acute respiratory distress syndrome (PARDS) in pediatric intensive care unit (PICU).Methods Fifty-six PADRS children were enrolled and the data of clinical characteristics,immunological status,complications,treatments and outcomes were collected and analyzed by using univariate and multivariate regression models.Results There were 20 children in the immunocompromised group and 36 in the control group.Immunocompromised children were older and weighted greater than the control ones (P=0.003 and P＜0.01,respectively).Peripheral blood leukocyte,neutrophil and platelet counts were significantly lower in IC group compared with control group (P=0.060,P=0.006 and P=0.023,respectively).In addition,high-frequency oscillatory ventilation (HFOV) was used less frequently in the IC group (P=0.015).The PICU mortality of the IC group was significantly higher than that of control group (P=0.003).The proportion of IC patients and the incidence of ventilator-associated lung injury differed significantly between survivors and non-survivors (P=0.003 and P=0.046,respectively).After adjusting for other confounding factors by using multivariate logistic regression analysis,IC was associated with a higher mortality (OR=6.986,95％ CI:1.812-26.930,P=0.005).Survival analysis also indicated that IC children with ARDS had lower 28-day survival rate than the non-IC children (P=0.022).Conclusions IC children with PARDS have a higher PICU mortality than children with normal immune function.Immunocompromise is an important predictor of poor outcomes in children with PARDS.

New insights into pediatric acute respiratory distress syndrome / 中华实用儿科临床杂志

Pediatric acute respiratory distress syndrome (PARDS) is one of the most severe disease in pediatric critical care medicine with high mortality.Pediatric practitioners have recognized that ARDS in children is different from ARDS in adults.In the absence of identification of these differences,however,children have been characterized as having ARDS based on the adult definitions.Therefore,the managements for PARDS were conducted without specific considerations of children,and have limitations when applied to patients.With the purpose to highlight the gaps of ARDS between children and adults,the new insights into PARDS on the epidemiology,pathophysiology,diagnosis,treatment and prognosis in the recent years were summarized.
