BACKGROUND Pre-transplant nutrition is a key driver of outcomes following liver transplantation in children. Patients with biliary atresia (BA) may have difficulty achieving satisfactory weight gain with enteral nutrition alone, and parenteral nutrition (PN) may be indicated. While PN has been shown to improve anthropometric parameters of children with BA listed for liver transplantation, less is known about the risks, particularly infectious, associated with this therapy among this specific group of patients. AIM To describe the incidence, microbiology, and risk factors of central line-associated bloodstream infection (CLABSI) among children with BA listed for liver transplantation. METHODS Retrospective review of children aged ≤ 2-years of age with BA who were listed for primary liver transplantation at Texas Children’s Hospital from 2008 through 2015 ( n = 96). Patients with a central line for administration of PN ( n = 63) were identified and details of each CLABSI event were abstracted. We compared the group of patients who experienced CLABSI to the group who did not, to determine whether demographic, clinical, or laboratory factors correlated with development of CLABSI. RESULTS Nineteen of 63 patients (30%, 95%CI: 19, 43) experienced 29 episodes of CLABSI during 4800 line days (6.04 CLABSI per 1000 line days). CLABSI was predominantly associated with Gram-negative organisms (14/29 episodes, 48%) including Klebsiella spp., Enterobacter spp., and Escherichia coli . The sole polymicrobial infection grew Enterobacter cloacae and Klebsiella pneumoniae . Gram-positive organisms (all Staphylococcus spp.) and fungus (all Candida spp.) comprised 9/29 (31%) and 6/29 (21%) episodes, respectively. No demographic, clinical, or laboratory factors were significantly associated with an increased risk for the first CLABSI event in Cox proportional hazards regression analysis CONCLUSION There is substantial risk for CLABSI among children with BA listed for liver transplantation. No clinical, demographic, or laboratory factor we tested emerged as an independent predictor of CLABSI. While our data did not show an impact of CLABSI on the short-term clinical outcome, it would seem prudent to implement CLABSI reduction strategies in this population to the extent that each CLABSI event represents potentially preventable hospitalization, unnecessary healthcare dollar expenditures, and may exact an opportunity cost, in terms of missed allograft offers.
Lichen sclerosus in young females can present as traumatic injuries on the vulva which can mimic sexual abuse. The case of an unconscious 6-year-old girl presenting in a reported inflicted drug overdose and with a clinical picture of ecchymosis and abrasions of the anogenital area is presented and discussed. The following case underscores the need for clinicians evaluating children for suspected abuse, to consider alternate conditions and causes that may not be related to sexual abuse.
Objectives The significance of antinuclear antibody (ANA) positivity in pediatric Hispanic patients with nonalcoholic fatty liver disease (NAFLD) is unknown. Methods ANA status was correlated with clinical, laboratory, and histologic parameters in Hispanic patients with a histologic diagnosis of NAFLD. Results Thirty-eight Hispanic children (27 male and 11 female) underwent liver biopsy at a median age of 12.1 years. Twenty patients (53%) had positive ANAs. The ANA-positive patients had higher fasting insulin levels (median [interquartile range (IQR)], 32.4 [25.4] µU/mL) and higher insulin resistance (median [Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) IQR], 5.9 [3.1]) than the ANA-negative patients (fasting insulin: median [IQR], 17 [13.9] µU/mL and median [HOMA-IR IQR], 3.5 [2.6] µU/mL; P = .05 and .01, respectively). Serum high-density lipoprotein (HDL) cholesterol levels were higher in the ANA-negative patients (median [IQR], 47 [18] mg/dL) than the ANA-positive patients (38 [12] mg/dL) (P = .03). There were no statistical differences in a series of demographic, clinical, laboratory, and histologic parameters between the ANA-positive and the ANA-negative patients. At a median follow-up of 2.6 years, alanine aminotransferase was significantly lower than the baseline levels in both groups. In 1 patient undergoing ANA retesting, the titer had normalized from a baseline of 1:1,280 3.8 years earlier. Conclusions In pediatric Hispanic patients with NAFLD, a positive ANA result is associated with insulin resistance and lower HDL cholesterol levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
