Abstract:
Objective To investigate the prevalence of vitamin D deficiency and to examine its relationship with the severity and prognosis in the critically ill children. Methods A total of 83 critically ill children admitted from November 1,2010 to December 9,2010 to Pediatric Intensive Care Unit in Beijing Children's Hospital,Capital Medical University were enrolled in the study. Serum 1,25 - Dihydroxyvitamin D concentration was measured by using an en-zyme - linked immunosorbent assay(ELISA). Anthropometric parameters such as height/ length and weight of the chil-dren were measured. Data collection also included primary disease,Pediatric Critical Illness Score(PCIS),the Pediatric Risk of Mortality Ⅲ(PRISM Ⅲ)score,multiple organ dysfunction syndrome( MODS)rate,mechanical ventilation rate,time of hospital of stay and the 28 - day survival rate. Results There were 32 cases with vitamin D deficiency on admission,vitamin D deficiency rate on admission was 38. 6% ,and there was no statistically significant difference among different primary disease groups(P = 0. 815). Vitamin D deficiency rate of malnutrition group was lower than that of the normal group[60. 0%(12 / 20 cases)vs 40. 0%(8 / 20 cases),χ2 = 5. 989,P = 0. 014]. PCIS scores of those with a normal vitamin D status was higher than those of the vitamin D deficiency group,showing a significant difference [(80. 47 ± 6. 18)scores vs(77. 16 ± 7. 59)scores,P = 0. 022]. PCIS score was positively correlated with the vitamin D level(r = 0. 267,P = 0. 015). There was no statistically significant difference among the PRISM score,MODS rate, mechanical ventilation rate,hospital stay length and the 28th day survival rate between the normal vitamin D group and the vitamin D deficiency group(all P ﹥ 0. 05). Conclusions A high prevalence of vitamin D deficiency is found in the critically ill children. The prevalence of vitamin D deficiency in children with malnutrition is higher. Vitamin D status may be correlated to the severity of the critically ill children,but the association with the prognosis is not obvious.
