    Evaluation of Lymphocyte Subgroups in Children With Down Syndrome
    (SAGE PUBLICATIONS INC, 2015) Yilmaz, Cahide; Dogan, Murat; Basarslan, Fatmagul; Yilmaz, Nebi; Yuca, Sevil; Bulan, Keziban; Kaya, Avni
    In this study, lymphocyte subgroups including blood CD3, CD4, CD8, CD4/CD8, CD19, and CD16.56 values were analyzed in children with Down syndrome (DS). The study includes 85 children with DS, followed at Department of Pediatrics, Faculty of Medicine, Yuzuncu Yil University and 64 healthy age-matched control participants. Blood CD3, CD4, CD8, CD4/CD8, CD19, and CD16.56 values were examined in both the groups. Significantly decreased blood CD3, CD4, and CD19 values were found in the study group (P < .05) when compared with the control group. In conclusion, we would like to emphasize that blood CD3, CD4, and CD19 levels were found to be decreased in children with DS. Based on these finding, we think that these decreased lymphocyte subgroups might be responsible for increased susceptibility to infections in children with DS.

    Objective: Hypernatraemia has serious complications such as brain injury, brain oedema and seizure. In this study, the incidence among children hospitalized hypernatremia, causes, development time, clinical features, and morbidity, and aimed to reveal the effect on mortality. Method: In this retrospective study, clinical and laboratory data from patients with hypernatremic were recorded. The study period was 33 months. The groups were separated into two groups; group I: Hypernatremia was present at hospital admission, group II: Hypernatremia was acquared after the hospitalization. Results: Overall incidence of hypernatraemia was 1.3% of all hospitalised children. While 42% of patients were from group I, 58% of patients had acquired hypernatremia during hospital stay. In group I, 61% of patients had infections on hospital admission. The most common cause of hypernatraemia in group II was neurological disorders (53%). The mortality rate was 30.5% (11/36) in patients with hypernatraemia on admission, 67.3% (33/49) in those with hospital-acquired hypernatraemia (P<0.05; significantly greater than for those with hypernatraemia on admission), and 51.7% (44/85) overall. Mean serum sodium level was higher in non-survivors than in survivors (161.7 +/- 8.3 mg/dL vs. 160 +/- 7.4 mg/dL), but the difference was not statistically significant. Similarly, there was no significant difference in peak serum sodium levels in survivors versus non-survivors, P>0.05. Conclusion: Hypernatraemia in pediatric age is associated with mortality and morbidity, and should be closely monitored in pediatric patients hospitalized for any reason in order to prevent complication.
