RESUMEN
INTRODUCTION: Hepatic artery occlusion (HAO) is a significant complication post-liver transplantation. Doppler ultrasound (DUS) has been widely used as an initial screening test for detecting HAO; however, its performance is often not sufficient. Although other diagnostic tests such as computed tomography angiography (CTA), magnetic resonance angiography (MRA), and angiogram are more accurate, they are invasive and have several limitations. Contrast-enhanced ultrasound (CEUS) is an emerging tool for detecting HAO; however, the results from previous studies were limited due to a small number of patients. Therefore, we aimed to evaluate its performance by performing a meta-analysis. METHOD: We performed a systemic review and meta-analysis of studies evaluating the performance of CEUS for the detection of HAO in an adult population. A literature search of EMBASE, Scopus, CINAHL, and Medline was conducted through March 2022. Pooled sensitivity, specificity, log diagnostic odd ratio (LDOR), and area under summary receiver operating curve (AUC) were calculated. Publication bias was assessed by Deeks' funnel plot. RESULT: Eight studies were included, with 434 CEUS performed. Using a combination of CTA, MRA, angiography, clinical follow-up, and surgery as the gold standard, the sensitivity, specificity, and LDOR of CEUS for detection of HAO were .969 (.938, .996), .991 (.981, 1.001), and 5.732 (4.539, 6.926), respectively. AUC was .959. The heterogeneity between studies appeared universally low, and no significant publication bias was found (p = .44). CONCLUSION: CEUS appeared to have an excellent performance for the detection of HAO and could be considered as an alternative when DUS is non-diagnostic or when CTA, MRA, and angiogram are not feasible.

BACKGROUND: The Coronavirus disease 2019 (COVID-19) pandemic disrupted patient care and worsened the morbidity and mortality of some chronic diseases. The impact of the COVID-19 pandemic on hospitalizations and outcomes in patients with cirrhosis both before and during different time periods of the pandemic has not been evaluated. AIMS: Describe characteristics of hospitalized patients with cirrhosis and evaluate inpatient mortality and 30-day readmission before and after the start of the COVID-19 pandemic. METHODS: Retrospective single-center cohort study of all hospitalized patients with cirrhosis from 2018 to 2022. Time periods within the COVID-19 pandemic were defined using reference data from the World Health Organization and Centers for Disease Control. Adjusted odds ratios from logistic regression were used to assess differences between periods. RESULTS: 33,926 unique hospitalizations were identified. Most patients were over age 60 years across all time periods of the pandemic. More Hispanic patients were hospitalized during COVID-19 than before COVID-19. Medicare and Medicaid are utilized less frequently during COVID-19 than before COVID-19. After controlling for age and gender, inpatient mortality was significantly higher during all COVID-19 periods except Omicron compared to before COVID-19. The odds of experiencing a 30-day readmission were 1.2 times higher in the pre-vaccination period compared to the pre-COVID-19 period. CONCLUSION: Inpatient mortality among patients with cirrhosis has increased during the COVID-19 pandemic compared to before COVID-19. Although COVID-19 infection may have had a small direct pathologic effect on the natural history of cirrhotic liver disease, it is more likely that other factors are impacting this population.

Syndromes characterized by congenital diarrhea, hearing loss, and intrahepatic cholestasis are uncommon and often misdiagnosed as progressive familial intrahepatic cholestasis (PFIC). Recent genetic studies have widened the array of genes linked with cholestatic disorders. Among these, UNC45A has recently been implicated in microvillous inclusion disease (MVID), although only a few cases exist. This case highlights a 20-year-old woman initially diagnosed clinically with PFIC type 1 during childhood. After ileal bypass at age 4 years, she had a resolution of intractable pruritus and cholestasis. Despite remaining symptom-free for over a decade, she returned in adulthood with recurrent cholestatic pruritus. Odevixibat was initiated for presumed PFIC while awaiting additional testing with symptomatic improvement and laboratory normalization. Whole genome sequencing identified novel compound heterozygous mutations in UNC45A and small bowel biopsies confirmed villous atrophy. Odevixibat, currently approved for cholestatic pruritus in PFIC and Alagille syndrome, demonstrates efficacy in managing cholestatic pruritus in MVID.
RESUMEN
Idiopathic granulomatous hepatitis is a rare condition characterized by hepatic granulomas with constitutional symptoms such as recurrent fevers, myalgias, and hepatosplenomegaly in the absence of infection or inflammatory disorder. Typical treatment and course of this disease consist of a course of steroids with rapid symptom resolution. However, symptoms may recur when steroids are tapered. In these circumstances, azathioprine, methotrexate, infliximab, and adalimumab have demonstrated good response. In this case, we present a patient who developed antidrug antibodies to infliximab and adalimumab and was the first documented case of this disease to be treated with certolizumab pegol. Our case highlights the novel efficacy of certolizumab pegol for idiopathic granulomatous hepatitis and its role in treating idiopathic granulomatous hepatitis with antidrug antibodies.
RESUMEN
BACKGROUND: Serum phosphatidylethanol (PEth) testing has emerged as a promising biomarker for assessing recent alcohol consumption, surpassing the limitations of self-reported data. Limited clinical data exists comparing PEth levels and patients' reported alcohol intake. AIMS: Compare PEth testing results with self-reported alcohol intake and assesses variables associated with underreporting. METHODS: Single-center retrospective cohort of patients with a diagnosis of chronic liver disease and serum PEth. A patient's first positive PEth (>/=10 ng/mL) and self-reported alcohol consumption was used. PEth results were categorized as mild (10-20), moderate (20-200), or heavy (>200). Severity measures between self-report and PEth were assessed using Bhapkar's test and Bonferroni-adjusted McNemar's tests. Demographic data was analyzed using Chi-Square tests. RESULTS: 279 patients were included. 94 (33.7%) patients had consistency with self-report, and 185 patients had inconsistencies in their report (66.3%, p < 0.001). Of 279 patients, 161 (57.7%) underreported their alcohol consumption, and 55 (19.7%) heavy PEth patients underreported alcohol consumption as light. 58% of alcohol-related and 56.4% of non-alcohol-related cirrhotic patients underreported their alcohol use. CONCLUSION: In our cohort, only one third of self-reported alcohol consumption was consistent with the PEth level. Notably, 57.7% underreported alcohol intake. Our study reinforces the clinical importance of PEth testing as an objective clinical measure.

According to the World Health Organization, approximately 20 million people worldwide are infected annually with the hepatitis E virus (HEV). There are four main genotypes of HEV. Genotype 1 and genotype 2 are common in developing countries and are transmitted by contaminated water from a fecal-oral route. Genotype 3 and genotype 4 are common in developed countries and can lead to occasional transmission to humans via undercooked meat. Hepatitis E virus 1 and HEV3 can lead to fulminant hepatitis, and HEV3 can lead to chronic hepatitis and cirrhosis in immunocompromised patients. The majority of patients with HEV infection are asymptomatic and usually have spontaneous viral clearance without treatment. However, infection in immunocompromised individuals can lead to chronic HEV infection. Both acute and chronic HEV infections can have extrahepatic manifestations. No specific treatment is required for acute HEV infection, no treatment has been approved in chronic infection, and no HEV vaccine has been approved by the (United States) Food and Drug Administration. This review focuses on the molecular virology (HEV life cycle, genotypes, model systems, zoonosis), pathogenesis, clinical manifestation, and treatment of chronic HEV infection, especially in immunocompromised patients, to provide clinicians a better understanding of the global distribution of these infections and the significant effect they can have on immunocompromised patients.
