Necrotizing Sarcoid Granulomatosis With Hepatic Involvement and Reversible Noncirrhotic Portal Hypertension.

Necrotizing sarcoid granulomatosis falls within the spectrum of sarcoidosis and is characterized by features of necrosis and granulomatous vasculitis. Like classical sarcoidosis, it can affect numerous organ systems, and there is a wide range of disease activity. Few cases of necrotizing sarcoid granulomatosis have been reported in the liver. We present a case of necrotizing sarcoid granulomatosis associated with noncirrhotic portal hypertension.

Diagnosis of morbid obesity may not impact healthcare utilization for orthotopic liver transplantation: A propensity matched study.

AIM: To study mortality, length of stay, and total charges in morbidly obese adults during index hospitalization for orthotopic liver transplantation. METHODS: The Nationwide Inpatient Sample was queried to obtain demographics, healthcare utilization, post orthotopic liver transplantation (OLT) complications, and short term outcomes of OLT performed from 2003 to 2011 (n = 46509). We divided patients into those with [body mass index (BMI) ≥ 40] and without (BMI < 40) morbid obesity. Multivariable logistic regression analysis was performed to characterize differences in in-hospital mortality, length of stay (LOS), and charges for OLT between patients with and without morbid obesity after adjusting for significant confounders. Additionally, propensity matching was performed to further validate the results. RESULTS: Of the 46509 patients who underwent OLT during the study period, 818 (1.8%) were morbidly obese. Morbidly obese recipients were more likely to be female (46.8% vs 33.4%, P = 0.002), Caucasian (75.2% vs 67.8%, P = 0.002), in the low national income quartile (32.3% vs 22.5%, P = 0.04), and have ≥ 3 comorbidities (modified Elixhauser index; 83.9% vs 45.0%, P < 0.001). Morbidly obese patient also had an increase in procedure related hemorrhage (P = 0.028) and respiratory complications (P = 0.043). Multivariate and propensity matched analysis showed no difference in mortality (OR: 0.70; 95%CI: 0.27-1.84, P = 0.47), LOS (ß: -4.44; 95%CI: -9.93, 1.05, P = 0.11) and charges for transplantation (ß: $15693; 95%CI: -51622-83008, P = 0.64) between the two groups. Morbidly obese patients were more likely to have transplants on weekdays (81.7%) as compared to those without morbid obesity (75.4%, P = 0.029). CONCLUSION: Morbid obesity may not impact in-hospital mortality and health care utilization in OLT recipients. However, morbidly obese patients may be selected after careful assessment of co-morbidities.

Effectively Screening for Coronary Artery Disease in Patients Undergoing Orthotopic Liver Transplant Evaluation.

Coronary artery disease (CAD) is prevalent in patients with end-stage liver disease and associated with poor outcomes when undergoing orthotopic liver transplantation (OLT); however, noninvasive screening for CAD in this population is less sensitive. In an attempt to identify redundancy, we reviewed our experience among patients undergoing CAD screening as part of their OLT evaluation between May 2009 and February 2014. Demographic, clinical, and procedural characteristics were analyzed. Of the total number of screened patients (n = 132), initial screening was more common via stress testing (n = 100; 75.8%) than coronary angiography (n = 32; 24.2%). Most with initial stress testing underwent angiography (n = 52; 39.4%). Among those undergoing angiography, CAD was common (n = 31; 23.5%). Across the entire cohort the number of traditional risk factors was linearly associated with CAD, and those with two or more risk factors were found to have CAD by angiography 50% of the time (OR 1.92; CI 1.07-3.44, p = 0.026). Our data supports that CAD is prevalent among pre-OLT patients, especially among those with 2 or more risk factors. Moreover, we identified a lack of uniformity in practice and the need for evidence-based and standardized screening protocols.
