Post-Transplant Hepatic Graft Fibrosis In Pediatric Liver-Inclusive Transplant Recipients, Hanh D. Vo

Theses & Dissertations

Hepatic graft fibrosis is a common histologic finding following pediatric liver transplant (LT) that may affect the long-term graft outcome. Hence, it is essential to identify hepatic graft fibrosis at a stage where fibrosis is not yet clinically apparent but has the potential for progression to initiate appropriate intervention and prevent its progression. Liver biopsy is the gold standard for fibrosis staging, but it is invasive, requires general anesthesia in children, and has potential complications. Our long-term goal is to implement non-invasive tests to assess and monitor the progression of hepatic graft fibrosis in liver-inclusive transplant children. The work presented …

Background: Intestinal inflammation and malabsorption in environmental enteric dysfunction (EED) are associated with early childhood growth faltering in impoverished settings worldwide.
Objectives: The goal of this study was to identify candidate biomarkers associated with inflammation, EED histology, and as predictors of later growth outcomes by focusing on the liver-gut axis by investigating the bile acid metabolome.
Methods: Undernourished rural Pakistani infants (n = 365) with weight-for-height Z score (WHZ) < -2 were followed up to the age of 24 mo and monitored for growth, infections, and EED. Well-nourished local children (n = 51) were controls, based on consistent WHZ > 0 and height-for-age Z score (HAZ) > -1 on 2 consecutive visits at 3 and 6 mo. Serum bile acid (sBA) profiles were measured by tandem MS at the ages of 3-6 …

Background: Growing evidence suggests that exposure to environmental chemicals, such as pesticides, impacts renal function and chronic kidney disease (CKD). However, it is not clear if pesticides may affect CKD progression and no studies exist in children.

Objectives: The objective of this study was to examine associations between serially measured urinary OP pesticide metabolites and clinical and laboratory measures of kidney function over time among children with CKD.

Methods: This study used data on 618 participants enrolled in the CKD in Children study (CKiD), a cohort study of pediatric CKD patients from the US and Canada. Children were followed over …

Background: Human adenosine deaminases (ADAs) modulate the immune response: ADA1

Methods: In a subgroup of the EPIC002-study, clinical data and plasma samples were collected from 540 Gambian infants at four time-points: day of birth; first week of life; one month of age; and four months of age. Concentrations of total extracellular ADA, ADA1, and ADA2 were measured by chromogenic assay and evaluated in relation to clinical data. Plasma cytokines/chemokine were measured across the first week of life and correlated to ADA concentrations.

Results: ADA2 demonstrated a steady rise across the first months of life, while ADA1 concentration significantly decreased 0.79-fold …
