RESUMEN

Objectives: Embolization of large portosystemic shunts effectively controls gastric variceal bleeding and prevents hepatic encephalopathy. The significance of dynamic changes in hepatic venous pressure gradient before and after embolization on clinical events and patient outcomes remains unknown. Methods: In this retrospective single-center series, 46 patients with gastric variceal bleeding, hepatic encephalopathy, or both undergoing embolization (January 2018 to October 2020) were included, and dynamic changes in portal pressures were analyzed against patient outcomes. Results: Males predominated. The most common portosystemic shunt syndrome was the lienorenal shunt. In all, 34 patients underwent embolization for hepatic encephalopathy and 11 for gastric variceal bleeding. The proportion of patients surviving at the end of 12 and 32 months was 86.96 and 54.35%, respectively. The hepatic venous pressure gradient before shunt embolization was 13.4 ± 3.2 and 16.9 ± 3.7 mm Hg after occlusion (p < 0.001). Bleeding from varices on overall follow-up was notable in five patients (10.9%), and overt hepatic encephalopathy in four (N = 42, 9.5%) patients at 6-12 months. The development of infections within 100 days and beyond the first year was associated with the risk of dying at the end of 12 and 32 months, respectively. Elevation of hepatic venous pressure gradient by >4 mm Hg from baseline and an absolute increase to >16 mm Hg immediately post-procedure significantly predicted the development of early- and late-onset ascites, respectively. Conclusion: Close monitoring for the development of infections and optimization of beta-blockers and diuretics after shunt embolization may improve clinical outcomes and help identify patients who will benefit from liver transplantation pending prospective validation.

RESUMEN

Alcohol-induced gut microbiota (GM) alterations are linked to alcohol use disorder (AUD) pathogenesis. Healthy donor stool transplant (fecal microbiota transplant [FMT]) reduced alcohol desire and improved clinical outcomes in small animal and human studies. Baseline and post-therapy-related GM changes in a real-world cohort with severe alcohol-related liver disease and AUD, patterns of drinking, and relapse have not been studied. We prospectively analyzed retrospective clinical data and stored samples to examine GM alterations in a cohort of severe alcohol-associated hepatitis (SAH) patients who underwent FMT or corticosteroid treatment followed for at least 12 months. The GM changes at baseline in the context of a pattern of drinking (binge vs. every day) and baseline and post-treatment alcohol relapse status (relapser vs. non-relapser). We identified 28 patients on FMT and 25 on corticosteroids who survived 1 year post-treatment. After necessary exclusions, the final cohort for various grouped GM analysis included 16 patients in the FMT arm and 14 on corticosteroids. Pedobacter and Streptophyta species at the commencement of treatment predicted alcohol relapse in steroid-ineligible patients receiving FMT and steroid-treated patients, respectively. At 6-12 months post-FMT, non-relapsers had elevated short-chain fatty acid-producing bacterial taxa linked with lower alcohol cravings. Alcohol relapse was significantly more in those on steroid therapy and was associated with the upregulation of the nucleotide metabolism pathway related to ethanol metabolism. We demonstrate pertinent baseline and post-treatment intestinal bacterial alterations that impact patterns of AUD patterns and relapse in SAH patients in the context of the therapy offered.

RESUMEN

During the coronavirus disease 2019 pandemic, Ayurvedic herbal supplements and homeopathic immune boosters (IBs) were promoted as disease-preventive agents. The present study examined the clinical outcomes among patients with chronic liver disease who presented with complications of portal hypertension or liver dysfunction temporally associated with the use of IBs in the absence of other competing causes. This single-center retrospective observational cohort study included patients with chronic liver disease admitted for the evaluation and management of jaundice, ascites, or hepatic encephalopathy temporally associated with the consumption of IBs and followed up for 180 days. Chemical analysis was performed on the retrieved IBs. From April 2020 to May 2021, 1022 patients with cirrhosis were screened, and 178 (19.8%) were found to have consumed complementary and alternative medicines. Nineteen patients with cirrhosis (10.7%), jaundice, ascites, hepatic encephalopathy, or their combination related to IBs use were included. The patients were predominantly male (89.5%). At admission, 14 (73.75%) patients had jaundice, 9 (47.4%) had ascites, 2 (10.5%) presented with acute kidney injury, and 1 (5.3%) had overt encephalopathy. Eight patients (42.1%) died at the end of the follow up period. Hepatic necrosis and portal-based neutrophilic inflammation were the predominant features of liver biopsies. IB analysis revealed detectable levels of (heavy metals) As (40%), Pb (60%), Hg (60%), and various hepatotoxic phytochemicals. Ayurvedic and Homeopathic supplements sold as IBs potentially cause the worsening of preexisting liver disease. Responsible dissemination of scientifically validated, evidence-based medical health information from regulatory bodies and media may help ameliorate this modifiable liver health burden.

RESUMEN

INTRODUCTION: Homeopathic remedies are highly diluted formulations without proven clinical benefits, traditionally believed not to cause adverse events. Nonetheless, published literature reveals severe local and non-liver-related systemic side effects. We present the first series on homeopathy-related severe drug-induced liver injury (DILI) from a single center. METHODS: A retrospective review of records from January 2019 to February 2022 identified 9 patients with liver injury attributed to homeopathic formulations. Competing causes were comprehensively excluded. Chemical analysis was performed on retrieved formulations using triple quadrupole gas chromatography-mass spectrometry and inductively coupled plasma atomic emission spectroscopy. RESULTS: Males predominated with a median age of 54 years. The most typical clinical presentation was acute hepatitis, followed by acute on chronic liver failure. All patients developed jaundice, and ascites were notable in one-third of the patients. Five patients had underlying chronic liver disease. COVID-19 prevention was the most common indication for homeopathic use. Probable DILI was seen in 77.8%, and hepatocellular injury predominated (66.7%). Four (44.4%) patients died (3 with chronic liver disease) at a median follow-up of 194 days. Liver histopathology showed necrosis, portal and lobular neutrophilic inflammation, and eosinophilic infiltration with cholestasis. A total of 29 remedies were consumed between 9 patients, and 15 formulations were analyzed. Toxicology revealed industrial solvents, corticosteroids, antibiotics, sedatives, synthetic opioids, heavy metals, and toxic phyto-compounds, even in 'supposed' ultra-dilute formulations. CONCLUSION: Homeopathic remedies potentially result in severe liver injury, leading to death in those with underlying liver disease. The use of mother tinctures, insufficient dilution, poor manufacturing practices, adulteration and contamination, and the presence of direct hepatotoxic herbals were the reasons for toxicity. Physicians, the public, and patients must realize that Homeopathic drugs are not 'gentle placebos.'

RESUMEN

Background: Severe alcohol-associated hepatitis (SAH) patients with infections have a high short-term mortality rate. Gut microbiota dysbiosis plays an important role in the pathogenesis of SAH. Preliminary studies have demonstrated long-term benefits with healthy donor fecal microbiota transplantation (FMT). Data on FMT compared with pentoxifylline for SAH and relevant gut microbial changes are lacking in literature. Methods: From January 2019 to February 2021, retrospective analysis of a single hospital's records revealed 47 SAH patients undergoing FMT (100 mL/day via nasoduodenal tube for 7 days) and 25 matched patients receiving pentoxifylline (400 mg/8 h for 28 days). The primary end point was a 6-month survival rate. Secondary end points included incidence of ascites, hepatic encephalopathy, infections, acute kidney injury, and gut microbiota changes between post-therapy groups. Biomarker discovery and network analysis were also performed to identify significant taxa of gut microbiota in post-treatment groups in retrospectively stored stool samples. Results: All were males. The 6-month survival rate was higher in the patients undergoing FMT than in patients receiving pentoxifylline (83.0% vs 56.0%, P = 0.012). At the end of 6-month follow-up, the incidences of clinically significant ascites (56.0% vs 25.5%, P = 0.011), hepatic encephalopathy (40.0% vs 10.6%, P = 0.003), and critical infections (52.0% vs 14.9%, P < 0.001) in patients administered pentoxifylline were significantly higher than those in patients treated with FMT. At 3 months, biomarker analysis revealed a significant abundance of Bifidobacterium and Eggerthella in the FMT group and the pentoxifylline group, respectively. At 6 months, Bifidobacterium in the FMT group and pathogenic Aerococcaceae in the pentoxifylline group were notable. Network analysis showed beneficial taxa (Bifidobacterium) as a central influencer in those undergoing FMT at 6 months. Conclusions: Healthy donor FMT improved survival rate and reduced liver-related complications compared with pentoxifylline. These clinical benefits were associated with favorable modulation of intestinal bacterial communities. Difficult-to-treat SAH patients may be safely bridged to transplantation using FMT. Controlled trials evaluating long-term outcomes are an unmet need.

RESUMEN

The immunomodulatory effect of Withania somnifera (WS) extract was tested in healthy adults. In this randomized placebo-controlled double-blinded study, subjects were allocated either 60 mg WS extract or placebo. It consists of a blinded 30-day period and an open-label extension study of another 30 days with crossover of only placebo to test. After the 30-day blinded study period, the WS test group reported significant increase (p < 0.05) in Ig's (IgA, IgM, IgG, IgG2, IgG3 and IgG4), Cytokines (IFN-γ, IL4), TBNK (CD45+, CD3+, CD4+, CD8+, CD19+, NK cells) whereas in the placebo group TBNK cells showed significant decrease (p < 0.05) and Ig's and cytokines showed no change (p > 0.05). In the extension period on day 60, the subjects on placebo who were crossed over to the WS test group showed significant increase (p < 0.05) in Ig's, cytokines and TBNK cells and the subjects who continued on the WS group showed a further significant improvement (p < 0.05) in Ig's, cytokines and TBNK cells. There were no adverse events reported in the study. WS extract significantly improved the immune profile of healthy subjects by modulating the innate and adaptive immune systems. Boosting the immune system of people at risk of infection and during widespread infections can be targeted with WS extract.

RESUMEN

During coronary artery bypass graft surgery, various arterial and venous conduits have been used to carry blood flow from the aorta to the coronary vasculature. Arterial conduits provide certain advantages over the saphenous vein, including superior long-term patency, relative resistance to the development of atherosclerosis, and greater endothelium-dependent relaxation. However, the perioperative release of catecholamines and thromboxane A, mechanical manipulation, and underlying endothelial cell dysfunction may result in vasoconstriction or vasospasm of the arterial conduit and a compromise of myocardial perfusion. Given these issues, pharmacologic therapy is frequently initiated intraoperatively to prevent vasospasm. Clevidipine is a rapidly acting calcium channel antagonist. Like nicardipine, it is a member of the dihydropyridine subgroup. Its rapid metabolism by tissue and plasma esterases results in an effective half-life of 1 to 3 minutes. We report, for the first time, the perioperative use of clevidipine to prevent vasospasm after coronary artery bypass graft surgery with the use of internal mammary artery and bilateral radial artery conduits. Its potential application in this scenario and advantages when compared with other commonly used agents is discussed.

RESUMEN

Perforation of the gallbladder occurs in 1.6%-2.8% of cases of gallbladder disease. Transhepatic rupture of the gall bladder is rare, with fewer than 20 cases reported in literature. We report a case of transhepatic rupture of the gall bladder with massive hemoperitoneum, which required emergency laparotomy and control of hemorrhage.
