Brain-Derived Neurotrophic Factor in Children and Adolescents with Cirrhosis Due to Biliary Atresia

BACKGROUND

The nutritional status in patients with cirrhosis is not so easy to assess properly. Considering the relationship between brain-derived neurotrophic factor (BDNF) and energy homeostasis, the main aim of this study was to evaluate the concentration of BDNF in children and adolescents with cirrhosis due to biliary atresia (BA) and correlate it with their nutritional status.

METHODS

Fifty-three children and adolescents with cirrhosis due to BA and 33 healthy controls were enrolled in this study. Nutritional status was evaluated using anthropometric parameters, and serum BDNF was measured by ELISA. Spearman coefficient was used to evaluate the correlation between variables.

RESULTS

In the cirrhosis group, 28.8% were undernourished and in the control group, 100% were well-nourished. BDNF median values for the control and cirrhosis group were 28.5 and 9.0 pg/ml respectively. BDNF and platelets were positively associated with both Standard Deviation Score (SDS) for height-for-age ratio and SDS for triceps skinfold thickness-for-age ratio.

CONCLUSIONS

Considering these associations, BDNF may be an indirect biomarker of nutritional status in children and adolescents with chronic liver disease. Further studies must be conducted to clarify the role of BDNF in this population.

Immunosuppressive Medication Adherence, Therapeutic Adherence, School Performance, Symptom Experience, and Depression Levels in Patients Having Undergone a Liver Transplant During Childhood

OBJECTIVES

This study sought to investigate immunosuppressive medication adherence, therapeutic adherence, school performance, symptom experiences, and depression levels of patients having undergone liver transplant during childhood.

MATERIALS AND METHODS

We performed a retrospective, cross-sectional, case-controlled study to compare the depression levels of subjects with those of their healthy peers. Data were collected between June 23, 2014, and July 10, 2014, from 0- to 18-year-old patients having undergone a liver transplant between 1996 and 2014 (n = 27; the participant's mean age, 17.59 y [SD = 4.29, min-max = 8-28 y]). The mean score for the immunosuppressant therapy adherence was 11.18. To collect the data, the Demographic and Clinical Characteristics Form, Immunosuppressant Therapy Adherence Scale, Therapeutic Regimen Adherence Assessment Questionnaire, School Performance Assessment Questionnaire, Modified Transplant Symptom Occurrence and Symptom Distress Scale-58, and Beck Depression Inventory were used. To analyze the data, descriptive statistics (frequencies, mean, and standard deviation), Mann-Whitney U test, and ridit scoring were used.

RESULTS

While the rate of adherence with clinical appointments was 55.5%, it was 33.3% with the diet (prescribed regimen) and 44.4% with exercise. While 33.3% of the participants repeated a grade or were held back, 44.4% of them missed more than 20 school days. Of the symptoms, the recipients mostly experienced anxiety, restlessness, nervousness, fatigue, and difficulty in concentrating. The patients' mean depression score was 7.77 when they were compared to their healthy peers, the difference was not statistically significant (P > .05).

CONCLUSIONS

In our study, the recipients' adherence with immunosuppressive therapy and clinical appointment was high. This study will provide data for the literature about pediatric liver transplant recipients' adherence with diet and exercise, and physiological and psychological symptoms such as fatigue and anxiety.
