Trends in the Utilization of Herbal and Dietary Supplements in Patients with Chronic Liver Disease During the SARS-CoV2 Pandemic.

Background: We studied the pattern of herbal and dietary supplement (HDS) use in patients with chronic liver disease (CLD) during the first year of the COVID-19 pandemic. Methods: A questionnaire/survey was sent to hepatology patients with CLD under the care of hepatologists at Johns Hopkins University School of Medicine. Results: The 5 most taken dietary supplements during the pandemic included vitamin B12 (27.7%), vitamin C (32.4%), vitamin D (54.6%), zinc (25.4%) and green tea extract (20.8%). Most participants (82.3%) did not discuss their HDS use with their hepatology providers. Conclusions: Healthcare providers should be mindful of potential HDS use in patients with CLD.

Preoperative Liver Stiffness is Associated With Hospital Length of Stay After Cardiac Surgery.

OBJECTIVES: Risk assessment models for cardiac surgery do not account for the degrees of liver dysfunction. Ultrasound shear-wave elastography measures liver stiffness (LSM), a quantitative measurement related to fibrosis, congestion, and inflammation. The authors hypothesized that preoperative liver stiffness would be associated with hospital length of stay after cardiac surgery. DESIGN: Prospective observational study. SETTING: University hospital, single center. PARTICIPANTS: One hundred five adult patients undergoing nonemergent cardiac surgery. INTERVENTIONS: Preoperative liver stiffness measured by ultrasound elastography. MEASUREMENTS AND MAIN RESULTS: The associations were analyzed using linear mixed models, with adjustments for preoperative variables, duration of cardiopulmonary bypass, and type of surgery. Median liver stiffness was 6.4 kPa (range, 4.1-18.6 kPa). The median length of hospital stay was 6 days (range, 3-18 d). Each unit increase in liver stiffness, treated as a continuous variable, was associated with an increase of 0.32 ± 0.10 days in the hospital (p = 0.002). When treated as a categorical variable (<6 kPa, 6-9.4 kPa, and ≥9.5 kPa), LSM ≥9.5 kPa v LSM <6 kPa was associated strongly with an increase in hospital length of stay of 3.25 ± 0.87 days (p = 0.0003). CONCLUSIONS: A preoperative LSM ≥9.5 kPa was associated with a significantly longer postoperative hospital length of stay. This association appeared independent of preoperative comorbidities commonly associated with coronary disease. Preoperative liver stiffness is a novel risk metric that is associated with the postoperative hospital length of stay after cardiac surgery.

Hepatitis C-positive donor liver transplantation for hepatitis C seronegative recipients.

BACKGROUND: The opioid crisis has led to an increase in hepatitis C virus-positive donors in the past decade. Whereas historically hepatitis C seropositive organs were routinely discarded, the advent of direct-acting antiviral agents has notably expanded the utilization of organs from donors with hepatitis C. There has been growing experience with liver transplantation (LT) from hepatitis C seropositive donors to hepatitis C seropositive recipients. However, data remain limited on LT from hepatitis C seropositive or hepatitis C ribonucleic acid positive donors to hepatitis C seronegative recipients. METHODS: We performed a retrospective study of 26 hepatitis C seronegative recipients who received hepatitis C seropositive donor livers followed by preemptive antiviral therapy with direct-acting antiviral treatment at the Johns Hopkins Hospital Comprehensive Transplant Center from January 1, 2017, to August 31, 2019. RESULTS: Twenty-five of the 26 recipients are alive with proper graft function; 20 of them received livers from hepatitis C nucleic acid testing positive donors. All 12 recipients who completed their direct-acting antiviral courses and have reached sufficient follow-up for sustained virologic response have achieved sustained virologic response. Nine of our recipients have either completed direct-acting antiviral treatment without sufficient follow-up time for sustained virologic response or are undergoing direct-acting antiviral treatment. One patient is awaiting antiviral treatment initiation pending insurance approval. Of note, 11 of 12 patients with sustained virologic response received a hepatitis C nucleic acid testing positive donor liver. CONCLUSION: Hepatitis C seronegative patients who receive a hepatitis C seropositive or hepatitis C nucleic acid testing positive liver allograft can enjoy good short-term outcomes with hepatitis C cure following direct-acting antiviral treatment.

Abdominal venous thrombosis presenting in myeloproliferative neoplasm with JAK2 V617F mutation: a case report.

INTRODUCTION: An unprovoked thombotic event in a patient is cause for further evaluation of an underlying hypercoaguable state. The investigation should include a thorough search, including checking for a variety of known inherited and acquired hypercoaguble states (protein C or S deficiency, anti-phospholipid antibodies, and anti-thrombin III deficiency) and gene mutations that predispose patients to an increased risk of clotting (for example, prothrombin gene 20210 mutation, factor V Leiden, and the JAK2 V617F mutation). CASE PRESENTATION: We report the case of a 38-year-old Caucasian woman with spontaneous, unprovoked abdominal venous thrombosis and demonstrate how testing for the JAK2 V617F mutation was useful in unmasking an underlying hypercoaguable state. CONCLUSIONS: JAK2 V617F-positive myeloproliferative neoplasm was diagnosed. This case illustrates the importance of testing for JAK2 V617F in patients presenting with Budd-Chiari syndrome, even in the absence of overt hematologic abnormalities, in order to establish a diagnosis of underlying myeloproliferative neoplasm.
