    Abstract Unlabelled: Nonalcoholic steatohepatitis (NASH) is an independent predictor of coronary artery disease (CAD). Our aim was to compare the incidence of cardiovascular (CV) events between patients transplanted for NASH and alcohol (ETOH)-induced cirrhosis. This is a retrospective cohort study (August 1993 to March 2010) of 242 patients (115 NASH and 127 ETOH) with ≥12 months follow-up after liver transplantation (LT). Those with hepatocellular carcinoma or coexisting liver diseases were excluded. Kaplan-Meier's and Cox's proportional hazard analyses were conducted to compare survival. Logistic regression was used to calculate the likelihood of CV events, defined as death from any cardiac cause, myocardial infarction, acute heart failure, cardiac arrest, arrhythmia, complete heart block, and/or stroke requiring hospitalization <1 year after LT. Patients in the NASH group were older (58.4 versus 53.3 years) and were more likely to be female (45% versus 18%; P < 0.001). They were more likely to be morbidly obese (32% versus 9%), have dyslipidemia (25% versus 6%), or have hypertension (53% versus 38%; P < 0.01). On multivariate analysis, NASH patients were more likely to have a CV event <1 year after LT, compared to ETOH patients, even after controlling for recipient age, sex, smoking status, pretransplant diabetes, CV disease, and the presence of metabolic syndrome (26% versus 8%; odds ratio = 4.12; 95% confidence interval = 1.91-8.90). The majority (70%) of events occurred in the perioperative period, and the occurrence of a CV event was associated with a 50% overall mortality. However, there were no differences in patient, graft, or CV mortality between groups.
    Conclusions: CV complications are common after LT, and NASH patients are at increased risk independent of traditional cardiac risk factors, though this did not affect overall mortality.

    Abstract Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) have poor efficacy in head and neck squamous carcinoma cells (HNSCC). Because the IGF-1 receptor (IGF1R) generates potent prosurvival signals and has been implicated in therapeutic resistance, its ability to induce resistance to EGFR-TKIs was studied in vitro. Five HNSCC cell lines showed reduced sensitivity to the EGFR-TKI gefitinib when the IGF1R was activated. In SCC-25 and Cal27 cells, gefitinib inhibited basal and EGF-stimulated EGFR, extracellular signal-regulated kinase (Erk), and Akt phosphorylation and reduced cell number. This correlated with initiation of apoptosis based on a 4-fold increase in PARP cleavage and a 2.5-fold increase in Annexin V positivity. The apoptotic response and reduction in cell number were blocked by IGF1R activation, which resulted in phosphorylation of both Erk and Akt. In both the cell lines, IGF1R-induced Erk, but not Akt, activation was eliminated by gefitinib. IGF1R-induced gefitinib resistance was unaffected by MAP/Erk kinase inhibition with U0126 but was partially impaired by inhibition of phosphoinositide-3-kinase with LY294002. The IGF1R-TKI PQ401 inhibited growth of SCC-25 and Cal27 cells alone and also acted synergistically with gefitinib. Thus, the IGF1R can make HNSCC cells resistant to EGFR-TKI treatment via a prosurvival mechanism. Of the 8 HNSCC tumor samples studied, all samples expressed the IGF1R and 5 showed detectable IGF1R phosphorylation, suggesting that this receptor may be relevant in vivo, and thus, combined EGFR/IGF1R inhibition may be necessary in some patients for effective targeted molecular therapy.
