Background and aims: Focal liver lesions (FLL) are one of the most common indications for hepatology and hepatobiliary surgery consultation. In this retrospective study, we aim to assess if contrast-enhanced ultrasound (CEUS) can address diagnostic dilemmas in the evaluation of indeterminate liver lesions by identifying characteristics of indeterminate FLL on CEUS and correlating these with cross-sectional imaging and pathology findings. Methods: We retrospectively reviewed all patients who underwent CEUS evaluation for liver lesions over a 28-month period (Oct 2020 to Jan 2023) at the University of Kentucky. To assess the relationship between CEUS results and the corresponding CT, MRI, and/or pathologic findings, the McNemar-Bowker tests were performed. Results: Twenty-nine patients were included (after two exclusions from a total n of 31). Mean age was 54 years, 62% were female, and 48% had underlying cirrhosis. Of the 29 patients with initial cross-sectional imaging, the initial results showed malignancy or likely malignant lesion in 6 patients and benign or likely benign lesion in 6 patients. The remaining 17 patients had inconclusive/indeterminate results. CEUS clarified an "indeterminate" CT/MRI result 15 times out of 17 (88.2%), moving the diagnosis to "benign" 11 times while suggesting "malignant" only four times. When aggregating indeterminate cross-sectional results with either benign or malignant categories suggested by CEUS, CEUS never reversed a benign CT/MRI diagnosis but often reversed a malignant CT/MRI diagnosis. Conclusion: CEUS provided a definitive diagnosis of indeterminate liver lesions in approximately 90% of patients and avoided the need for biopsy in most patients. In cases where the liver lesions were biopsied, CEUS accurately distinguished malignant versus benign lesions as confirmed by biopsy findings. CEUS, therefore, has the potential to provide a precise diagnosis for the majority of indeterminate lesions.

Background: The anatomy of the biliary tree is complex with anatomical variations which can be found in ~50% of the patients. Purpose: Existing research on these variations primarily stems from studies in developed countries, with uncertain applicability to the Ugandan population due to noted ethnic differences in incidence rates. Objective: The study was aimed at describing the anatomical variations of the gallbladder and bile ducts. Methods: This retrospective cross-sectional study conducted at Kampala MRI Centre from January 2017 to December 2022 analyzed MRCP images and reports from 231 patients to document gallbladder and bile duct variations. Results: 53.2% of patients exhibited typical cystic duct anatomy, and 51% had Type 1 variations in intrahepatic ducts. Importantly, the study identified a significant correlation between age and common bile duct diameter. Conclusion: The findings showed various anatomical variations that were slightly higher in the study population than those reported in the literature. This study emphasizes the critical need for comprehensive knowledge to enhance surgical safety, minimize iatrogenic trauma, and improve the accuracy of diagnostic imaging and hepatobiliary procedures.

One of the most common chronic liver diseases is nonalcoholic fatty liver disease (NAFLD), which affects many people around the world. Gut microbiota (GM) dysbiosis seems to be an influential factor in the pathophysiology of NAFLD because changes in GM lead to fundamental changes in host metabolism. Therefore, the study of the effect of dysbiosis on the pathogenicity of NAFLD is important. European clinical guidelines state that the best advice for people with NAFLD is to lose weight and improve their lifestyle, but only 40% of people can achieve this goal. Accordingly, it is necessary to provide new treatment approaches for prevention and treatment. In addition to dietary interventions and lifestyle modifications, GM modification-based therapies are of interest. These therapies include probiotics, synbiotics, fecal microbiota transplantation (FMT), and next-generation probiotics. All of these treatments have had promising results in animal studies, and it can be imagined that acceptable results will be obtained in human studies as well. However, further investigations are required to generalize the outcomes of animal studies to humans.

Despite the promising role of renal replacement therapy (RRT) in acute liver failure (ALF), high-risk patients need liver transplantation and remain at risk for death due to cerebral complications. The objective of this study was to report outcomes of living donor liver transplantation (LDLT) for ALF with perioperative RRT. This was a single-center retrospective cohort study. Out of 1167 LDLTs, 24 patients had ALF and met the King's College criteria for transplantation. They were categorized into no-RRT (n = 13) and RRT (n = 11) groups. We looked at 1-year posttransplant survival in these patients. The median serum ammonia level at the time of transplant in the no-RRT and RRT groups was 259.5 mcg/dL (222.7-398) and 70.6 mcg/dL (58.1-92.6) (p = 0.005). In the RRT group, serum ammonia level < 100 mcg/dL was achieved in all patients. Seven (53.8%) patients in the no-RRT group and 11/11 (100%) in the RRT group were extubated and regained full consciousness after LDLT (p = 0.013). The 90-day mortality was 6/13 (46.1%) and 2/11 (18.1%) (p = 0.211). There was no brainstem herniation-related mortality in the RRT group, that is, 5/13 (38.4%) and 0/11 (0%) (p = 0.030). The 1-year posttransplant survival was also significantly higher in the RRT group (p = 0.031). The use of RRT lowers serum ammonia levels and might reduce posttransplant mortality due to brainstem herniation.

Background: Early detection of progressive liver damage in chronic liver disease (CLD) patients is crucial for better treatment response. Several studies have shown the association of microRNA (miRNA) in the progression of CLD in regulating cell proliferation, fibrosis, and apoptosis as well as in carcinogenesis. Objectives: The study was aimed at determining the expression of miRNA-221 among different stages of fibrosis in CLD patients due to hepatitis B virus (HBV) and nonalcoholic fatty liver disease (NAFLD) and thus evaluate its role as an early biomarker in CLD. Methods: A total of 100 participants (75 CLD patients and 25 healthy control) were recruited in this cross-sectional study and divided into four groups, of which 25 as healthy control, 25 in CLD without fibrosis, 25 were CLD with fibrosis, and 25 were CLD with cirrhosis. Total RNA was extracted from plasma followed by cDNA synthesis, and finally, the expression of miRNA-221 was analyzed for its diagnostic potential as a single biomarker using the qRT-PCR method. Results: The plasma level of miRNA-221 was significantly upregulated in different fibrosis stages of CLD (p < 0.05), and this upregulation was positively correlated with the progression of fibrosis (p < 0.05). Significantly increased expression of miRNA-221 was found in NAFLD patients compared to HBV patients in the CLD without fibrosis patient group (p < 0.05), while expression of miRNA-221 was significantly upregulated among HBV patients in the CLD with the fibrosis group. miRNA-221 showed high diagnostic accuracy in discriminating different stages of fibrosis from healthy control (p < 0.05). Conclusion: miRNA-221 may be used as a potential plasma biomarker for early prediction of fibrosis progression in CLD patients.

Background: Cirrhosis incidence in older adult patients has been increasing with limited data on their survival. This study is aimed at investigating the survival and disease progression in older adult patients with cirrhosis compared to younger patients. Methods: This is a retrospective single-center study. Patients aged above 50 with a confirmed diagnosis of cirrhosis based on biopsy, FibroSure test, splenomegaly, and low platelets < 120 × 10⁹/L) or imaging findings including FibroScan were included. Patients with active substance abuse, transjugular intrahepatic portosystemic shunt (TIPS), prior spontaneous bacterial peritonitis (SBP), variceal hemorrhage, model for end-stage liver disease-Na (MELD - Na) ≥ 20, had liver transplantation, malignancy except for squamous cell carcinoma, and other comorbidities such as congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and end-stage kidney disease with glomerular filtration rate (GFR) < 30 were excluded. Patients' records from the liver clinic were reviewed and demographics, laboratory, and compensation and decompensation status were collated. Patients were separated into two groups based on age 50-64 years and age ≥ 65. The primary endpoint was death, and the secondary endpoint was disease progression measured by the baseline to 12-month increase in MELD-Na score. The Kaplan-Meier analysis was conducted to compare the survival between the two groups. Cox regression analysis was performed to identify independent risk factors for poor survival. Results: A total of 191 patients diagnosed with cirrhosis met the inclusion and exclusion criteria. There were 80 patients aged 50-64 years and 111 patients aged ≥ 65 years. Significantly shorter survival times were seen among patients aged ≥ 65 years compared to those aged 50-64 years (73.3 ± 4.8 vs. 151.5 ± 22.7; p < .001). Age of diagnosis ≥ 65 years (p < 0.001), male gender (p = .013), body mass index (BMI) < 30 (p = 0.005), and decompensation (p = 0.008) were found to be independent risk factors for poor survival. MELD-Na scores increased significantly in 12 months of follow-up from baseline, but only in patients with decompensated cirrhosis (p = 0.013). Conclusions: Cirrhotic patients aged ≥ 65 years have significantly poor survival compared to younger patients. A prospective study is needed to further investigate the effect of age and obesity on survival and disease progression in older adult patients with cirrhosis.

Background: Liver biopsy as the gold standard for assessing the degree and diagnosis of fibrosis still has significant drawbacks, which make the emergence of a much less invasive diagnostic marker possible. M2BPGi levels and the AGAP score, the two newest serological markers, are known to have good sensitivity for detecting liver fibrosis. This study is aimed at determining the validity of examining M2BPGi levels and AGAP scores on the Fibroscan examination as markers of noninvasive test for liver fibrosis in chronic hepatitis B patients.

Methods: This is an observational, descriptive study with a retrospective design. This study used secondary data taken from medical records and blood specimen research materials of outpatients at the Hepatology Gastroenterology Polyclinic at a tertiary general hospital in West Java, Indonesia, with a diagnosis of chronic hepatitis B.

Results: There were 109 research subjects included. There were 73 (66.9%) subjects with no- or low-grade fibrosis and 36 (33.1%) with advanced fibrosis. The sensitivity and specificity of the M2BPGi were 88.9% and 61.6% (PPV 55.3%; NPV 91.8%; AUC 0.753), while the AGAP score was 47.2% and 100% (PPV 100%; NPV 79.3%; AUC 0.736). The combined M2BPGi level and the AGAP score showed a sensitivity of 80.9% and a specificity of 100% (PPV 100%; NPV 91.8%; AUC 0.905).

Conclusion: The AGAP score and M2BPGi levels together are a better way to measure the degree of liver fibrosis in people with chronic hepatitis B than either M2BPGi or the AGAP score alone.

We aimed to analyze the different patient characteristics and treatment outcomes (such as sustained viral response, SVR) between incarcerated patients with chronic hepatitis C (CHC) and those with CHC from the outpatient department through an on-site integrated screening and microelimination program in a detection center. In this retrospective study, which ran from May 2021 to April 2022, we included 32 consenting male prisoners aged at least 20 years who were willing to participate in the study. Members of the control group (who received DAAs in an outpatient setting) were selected from the treated CHC patient databank of individuals who received DAA regimens at Chi Mei Hospital between January 2021 and December 2022. The patients in the two groups did not differ significantly in terms of age, FIB-4 score, HCV RNA, HBV coinfection, hemogram findings, coagulation profiles, and renal function tests. However, the patients in the incarcerated group had a significantly different genotype distribution compared to the control group, significantly lower liver enzyme levels, and higher albumin and bilirubin levels compared to those in the control group. The rate of SVR to DAA treatment obtained among incarcerated patients did not differ significantly from that obtained among patients in the control group. Loss to follow-up (for several reasons) is a major reason for treatment discontinuation among these patients.

Background: In spite of the scientific evidence supporting health advantages of mushrooms, some of them are seriously poisonous. The clinical picture of mushroom intoxication ranges from minor gastrointestinal symptoms to organ failure, such as liver failure and death.

Method: We provided demographics, clinicopathological characteristics, applied treatments, and outcomes of mushroom poisoning by Lepiota species in a series of 18 cases that were referred from Kermanshah and Lorestan provinces to Abu-Ali-Sina Hospital, Shiraz, Iran. Clinical and paraclinical data were collected by taking history and reviewing of medical documents. Pathologic findings were extracted through a review of hematoxylin and eosin pathologic slides.

Results: The patients were between the ages of 18 and 67 years, composed of ten females and eight males. The most frequent clinical manifestations were nausea and vomiting followed by abdominal pain. Four cases presented decreased consciousness on admission. One of them passed away. Three other cases underwent liver transplantation, two of them died after transplantation, and one fully recovered without any major issues. All instances had elevated ALT levels, which ranged from 44 to 9,140 IU/L (mean: 3259 ± 2476), with most of them also having concurrent AST elevations (mean: 1,361 ± 1,532). Only few patients had modest elevations in alkaline phosphatase. Total and direct bilirubin elevations up to 47.6 and 24 mg/dL, respectively, were found in most cases. Decreased total protein and albumin concentrations and increased BUN and creatinine levels were observed in some patients. In addition, some instances revealed increased LDH, increased WBC, decreased hemoglobin, and decreased platelet count. Most patients had increased prothrombin time; hematuria and positive stool occult blood were observed in few patients. Histopathologic examination of three explanted livers revealed massive necrosis with moderate to severe macrovesicular steatosis, significant ductular reaction, and parenchymal inflammation. Other patients followed a recovery process with a considerable drop in liver enzymes, especially ALT, during hospitalization utilizing conservative treatment. They had no liver problems or relevant issues after a two-year follow-up.

Conclusion: In our study, highly elevated liver enzymes with a significantly high ALT/AST ratio were observed in cases of mushroom poisoning by Lepiota species, leading to fulminant liver failure and death in some cases. These laboratory findings were correlated with liver necrosis and macrovesicular steatosis in explanted livers.
