The role of noninvasive liver disease assessment by two-dimensional shear wave elastography (2D-SWE) to diagnose fibrosis is well described in patients with chronic liver disease. However, its role in prognosis, especially after liver transplantation (LT) has not been adequately examined. We hypothesized that elevated liver stiffness measurement (LSM) as measured by 2D-SWE after LT predicts future morbidity and mortality independent of fibrosis by liver biopsy.In a prospective cohort study, consecutive LT recipients underwent concomitant protocol 2D-SWE and protocol liver biopsy (2012)(2013)(2014), with the assessor blinded to biopsy findings. We examined the baseline correlation of LSM with fibrosis stage and the association between elevated LSM and the development of subsequent clinical outcomes and all-cause mortality. A total of 187 LT recipients (median age 58 years, 38.5% women, median body mass index 26.5 kg/m 2 , 55.1% hepatitis C virus, 17.6% nonalcoholic steatohepatitis/cryptogenic) were examined. Median time between LT and biopsy/2D-SWE assessment was 4.0 years, and the median follow-up time after LSM determination was 3.5 years. Median LSM was 9 kPa (8 kPa [F0/F1], 11.5 kPa [F2], 12 kPa [F3/ F4]). There was a positive correlation between LSM and fibrosis stage (r s = 0.41; p < 0.001). LSM ≥11 kPa was associated with lower survival within 3 years (84.8 vs. 93.7%; p = 0.04). After adjusting for age, sex, and fibrosis stage, LSM ≥11 kPa was independently associated with mortality (hazard ratio, 2.45; 95% confidence interval, 1.08-5.60). Elevated LSM by 2D-SWE is associated with increased mortality after LT independent of hepatic fibrosis. Given the overall decrease in the use of liver biopsy in the current era, 2D-SWE may serve as a novel noninvasive prognostic tool to predict relevant outcomes late after LT.
A 55-year-old woman taking over-the-counter (OTC) glucosamine developed symptomatic hepatotoxicity. Several of her liver enzymes were elevated to 10 times the upper limit of normal. One week after discontinuing glucosamine, serum transaminases fell dramatically, with some returning to normal limits. Four weeks after glucosamine was discontinued, all her liver tests were normal. Rechallenge was not attempted. The potential causes of hepatocellular injury were evaluated. Glucosamine is a dietary supplement available in a wide variety of commercial preparations, primarily used for joint relief in osteoarthritis. Despite the extensive use of glucosamine supplements, significant elevations of transaminases are rare. The mechanism of hepatotoxicity in many OTC herbal preparations is unknown. It is vital for physicians to elicit a careful history of OTC medications and educate their patients on their potential adverse effects.
Spindle cell carcinoma of the breast is a rare subtype of metaplastic carcinoma with likelihood of aggressive behavior and lack of specific treatment options. Spindle cell carcinomas of the breast are typically "Triple Negative" and have distinct clinical, radiographic and pathological characteristics. We present, in this report, the case of a woman diagnosed with spindle cell carcinoma of the breast, and review the literature on this rare but intriguing disease.
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.
