RÉSUMÉ

Objective To assess the performance of pediatric clinical illness score (PCIS), pediatric risk of mortality scoreⅢ(PRISMⅢ), pediatric logistic organ dysfunction score 2 (PELOD-2), and pediatric multiple organ dysfunction score (P-MODS) in predicting mortality in critically ill pediatric patients. Methods The data of critically ill pediatric patients admitted to Pediatric Intensive Care Unit (PICU) of First Affiliated Hospital of Sun Yat-Sen University from August 2012 to May 2017 were retrospectively analyzed. The gender, age, basic diseases, the length of PICU stay were collected. The children were divided into survival group and non-survival group according to the clinical outcome during hospitalization. The variables of PCIS, PRISMⅢ, PELOD-2, and P-MODS were collected and scored. Receiver operating characteristic (ROC) curve was plotted, the efficiency of PCIS, PRISMⅢ, PELOD-2, and P-MODS for predicting death were evaluated by the area under ROC curve (AUC). Hosmer-Lemeshow goodness of fit test was used to evaluate the fitting degree of each scoring system to predict the mortality and the actual mortality. Results Of 461 critically ill children, 35 children were excluded because of serious data loss, hospital stay not exceeding 24 hours, and death within 8 hours after admission. Finally, a total of 426 pediatric patients were enrolled in this study. 355 pediatric patients were survived, while 71 were not survived during hospitalization, with the mortality of 16.7%. There was no significant difference in gender, age, underlying diseases or length of PICU stay between the two groups. PCIS score in non-survival group was significantly lower than that of survival group [80 (76, 88) vs. 86 (80, 92)], and PRISMⅢ, PELOD-2 and P-MODS scores were significantly increased [PRISMⅢ: 16 (13, 22) vs. 12 (10, 15), PELOD-2: 6 (5, 9) vs. 4 (2, 5), P-MODS: 6 (4, 9) vs. 3 (2, 6), all P < 0.01]. ROC curve analysis showed that the AUCs of PCIS, PRISMⅢ, PELOD-2, and P-MODS for predicting death of critical ill children were 0.649, 0.731, 0.773, and 0.747, respectively. Hosmer-Lemeshow test showed that PCIS predicted the mortality and the actual mortality in the best fitting effect (χ2= 7.573, P = 0.476), followed by PELOD-2 and P-MODS (χ12 = 9.551, P1= 0.145; χ22 = 10.343, P2= 0.111), while PRISMⅢ had poor fitting effect (χ2= 43.549, P < 0.001). Conclusions PRISMⅢ, PELOD-2 and P-MODS can discriminate between survivors and moribund patients well, and assessing the condition of critically ill pediatric patients with relatively accuracy. PCIS was the best fitting effect in predicting mortality and actual mortality, followed by PELOD-2 and P-MODS, while PRISMⅢ had poor fitting effect.

RÉSUMÉ

Objective To identify a novel pathogenicity mutation of acid alpha‐glucosidase(GAA) gene in a Chinese family with two siblings affected with juvenile onset form glycogen storage disease Ⅱ(GSD Ⅱ) .Methods The clinical and family data of two siblings presenting recurrent respiratory tract infections ,respiratory failure associated with systemic muscle weakness ,were an‐alyzed and diagnosed with GSD Ⅱ by detecting alpha‐1 ,4‐glucosidase activity .DNA was extracted from peripheral blood of the proband ,younger brother and his parents .All 20 exons and the intron‐exon splice sites of GAA gene were amplified by polymerase chain reaction (PCR) .Mutations were detected by direct sequencing the PCR products .Results The younger brother was found to be compound heterozygous for two mutations in the GAA gene :c .1216G>A (p .Asp406Asn) missense mutation in the exon 8 from his father and c .1935C>A (p .Asp645Glu) missense mutation in the exon 14 from his mother .Conclusion The compound hetero‐zygous c .1216G>A and c .1935C>A mutations caused the juvenile onset form GSD Ⅱ characterized by dyspnea and cardiac hyper‐trophy .The novel c .1216G>A mutation may be related to the juvenile onset form GSD Ⅱ .
