Background:
and Purpose Liver enzymes (aspartate aminotransferase [AST], alanine aminotransferase [ALT], and gamma-glutamyl transpeptidase [GGT]) are glutamate-regulatory enzymes, and higher glutamate levels correlated with worse prognosis of patients with neurotrauma. However, less is known about the association between liver enzymes and incidence of stroke. We evaluated the association between serum levels of AST, ALT, and GGT and incidence of stroke in the Atherosclerosis Risk in Communities (ARIC) study cohort from 1990 to 1992 through December 31, 2016.
Methods:
We included 12,588 ARIC participants without prevalent stroke and with data on liver enzymes ALT, AST, and GGT at baseline. We used multivariable Cox regression models to examine the associations between liver enzymes levels at baseline and stroke risk (overall, ischemic stroke, and intracerebral hemorrhage [ICH]) through December 31, 2016, adjusting for potential confounders.
Results:
During a median follow-up time of 24.2 years, we observed 1,012 incident strokes (922ischemic strokes and 90 ICH). In age, sex, and race-center adjusted models, the hazard ratios (HRs; 95% confidence intervals [CIs]) for the highest compared to lowest GGT quartile were 1.94 (95% CI, 1.64 to 2.30) for all incident stroke and 2.01 (95% CI, 1.68 to 2.41) for ischemic stroke, with the results supporting a dose-response association (P for linear trend <0.001). Levels of AST were associated with increased risk of ICH, but the association was significant only when comparing the third quartile with the lowest quartile (adjusted HR, 1.82; 95% CI, 1.06 to 3.13).
Conclusions
Elevated levels of GGT (within normal levels), independent of liver disease, are associated with higher risk of incident stroke overall and ischemic stroke, but not ICH.

Purpose:
Cholestatic complications remain a primary cause of post-liver transplantation (LTX) morbidity in pediatric patients. Standard biliary access by endoscopic retrograde cholangioscopy may not be feasible due to modified biliary drainage. Percutaneous transhepatic biliary drainage (PTCD) may be performed alternatively. However, systematic data concerning safety and efficacy of PTCD in these patients are scarce.
Methods:
In this retrospective study, procedural and safety characteristics of PTCD in pediatric patients following LTX were analyzed. We compared laboratory indicators of inflammation, cholestasis, and graft function before and at 6 and 12 months after the first PTCD insertion. Efficacy was analyzed by percentage of patients without cholangitis, need for surgical biliary re-intervention and re-transplantation during a follow-up period of 60 months.
Results:
Over a decade, PTCD was attempted in a total of 15 patients, with technical success (93.3%) in 14 patients. Periprocedural complications, including bleeding (7.1%) and cholangitis (21.4%) were observed in patients. During follow-up, both MELD-score (baseline:13 [8–15] vs. 12 months: 8 [7–8], p<0.001) and parameters of cholestasis (GGT: baseline: 286 [47–458] U/L vs. 12 months: 105 [26–147] U/L, p=0.024) decreased. Prior to PTCD, cholangitis (64.3%) and cholangiosepsis (21.4%) were common complications. In contrast, following PTCD, cholangitis occurred in only one patient (7.1%). Five patients (35.7%) needed surgical biliary re-intervention and two (14.3%) required re-transplantation.
Conclusion
PTCD in pediatric patients following LTX had an acceptable safety profile, demonstrating a biochemical improvement of both cholestasis and graft function and may prevent cholestatic complications, thus reducing the need for surgical re-intervention and re-transplantation.
