BACKGROUND & AIMS Liver stiffness measurement (LSM), using elastography, can independently predict outcomes of patients with chronic liver diseases (CLDs). However, there is much variation in reporting and consistency of findings. We performed a systematic review and meta-analysis to evaluate the association between LSM and outcomes of patients with CLDs. METHODS We performed a systematic review of the literature, through February 2013, for studies that followed up patients with CLDs prospectively for at least 6 months and reported the association between baseline LSM and subsequent development of decompensated cirrhosis or hepatocellular carcinoma (HCC), as well as mortality. Summary relative risk (RR) estimates per unit of LSM and 95% confidence intervals (CIs) were estimated using the random effects model. RESULTS Our final analysis included 17 studies, reporting on 7058 patients with CLDs. Baseline LSM was associated significantly with risk of hepatic decompensation (6 studies; RR, 1.07; 95% CI, 1.03–1.11), HCC (9 studies; RR, 1.11; 95% CI, 1.05–1.18), death (5 studies; RR, 1.22; 95% CI, 1.05–1.43), or a composite of these outcomes (7 studies; RR, 1.32; 95% CI, 1.16–1.51). We observed considerable heterogeneity among studies—primarily in the magnitude of effect, rather than the direction of effect. This heterogeneity could not be explained by variations in study locations, etiologies and stages of CLD, techniques to measure liver stiffness, adjustment for covariates, or method of imputing relationship in the meta-analysis. CONCLUSIONS Based on a meta-analysis of cohort studies, the degree of liver stiffness is associated with risk of decompensated cirrhosis, HCC, and death in patients with CLDs. LSM therefore might be used in risk stratification.

A 62-year-old man with chemotherapy-naive, castration-resistant metastatic prostate cancer presented with refractory diarrhea despite prolonged high-dose corticosteroid treatment after receiving 3 doses of ipilimumab as part of a phase 3 clinical trial. The investigative work-up and response to a gluten-free diet essentially confirm celiac disease. Although ipilimumab-induced enterocolitis is a well-reported complication, there have been no reported cases of celiac disease with ipilimumab therapy, to our knowledge. We suspect that ipilimumab may have amplified the symptomatic presentation of previously unrecognized celiac disease or perhaps even triggered the disease itself. With ipilimumab being used more commonly in the treatment of melanoma and prostate cancer, we believe that physicians should be aware of this potential adverse outcome when evaluating a patient who experiences persistent diarrhea during or after ipilimumab treatment.

LGI EUS FNA is associated with a high rate of serious grades 3-4 AEs. This may reflect the total number of associated interventions and the frequency of underlying pathology and symptoms.
