Acute liver failure and aplastic crisis due to anorexia nervosa in an adolescent girl: a case report.

Anorexia nervosa (AN) has a high mortality rate due to the widespread organ dysfunction caused by the underlying severe malnutrition. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases, while acute liver failure and aplastic crisis related to coagulation disease and encephalopathy rarely occur in AN patients. The supervised increase of caloric intake can quickly improve the elevated aminotransferases caused by starvation and aplastic crisis. This current case report describes a 12-year-old adolescent girl who was admitted with a 3-month history of weight loss. Within 3 months, she had lost 10 kg of weight. The girl was diagnosed with AN, acute liver failure, severe malnutrition with emaciation, electrolyte disorder, bradycardia and aplastic crisis. She was gradually supplemented with vitamins and enteral nutrition to avoid refeeding syndrome. After treatment, her liver function and haematopoietic function returned to normal. In conclusion, acute liver failure and aplastic crisis are rare but potentially life-threatening complications of AN, which could be improved by supervised feeding and timely rehydration. AN should be considered as the potential aetiology of acute liver failure and aplastic crisis.

Acute Fulminant Hepatic Failure in 23-Year-Old Female Taking Homeopathic Remedy.

Homeopathic remedies made primarily from eggshells, and therefore calcium, can be marketed for treatment of back pain and vaginal discharge. We present a case of a 23-year-old otherwise healthy woman who presented with acute liver failure (ALF) ultimately requiring liver transplantation as a result of taking increased doses of a homeopathic product with the primary ingredient of eggshells. Although relatively uncommon compared with medications such as acetaminophen, herbal supplements have been reported to cause drug-induced liver injury (DILI), thought to be primarily due to contaminants. This is the first known report of DILI resulting from a homeopathic product with the primary ingredient of eggshells, and it demonstrates the importance of early ALF recognition and treatment, as well as the importance of practicing caution when using homeopathic supplements.

Liver Transplantation for Acute Liver Failure Due to Yellow Phosphorus Poisoning - A Comprehensive Review.

Yellow phosphorus or metal phosphide (YP-MP) rodenticide poisoning has been a known cause of acute liver failure (ALF) in many countries of Asia and North and South America over the last decade. It is a highly toxic compound and is a well-known cause of intentional or accidental poisoning in both adults and children. In lower doses, it causes gastrointestinal symptoms and mild hepatic injury, and patients may spontaneously recover. In higher doses, hepatic necrosis and fatty infiltration may cause significant injury and may even lead to ALF, characterized by hepatic encephalopathy, coagulopathy, and lactic acidosis. Cardiotoxicity, rhabdomyolysis, and neutropenia are other well-documented complications. If untreated, it may lead to multi-organ dysfunction and death. Plasmapheresis and continuous renal replacement therapy (CRRT) have been used with limited success in patients who do not recover spontaneously. However, patients who develop ALF often need liver transplantation (LT). Liver transplantation has been successfully performed in ALF due to YP-MP poisoning in several countries, with good results in both adult and pediatric patients. Separate criteria for LT are important to ensure early and rapid listing of critical patients on the waiting list. The success rates of LT for ALF due to YP-MP rodenticide poisoning are very promising, provided there are no contra-indications to transplant. Plasma exchange, CRRT, or cytosorb can be used as a bridge to transplant in selected patients. In the long term, only with an increase in public awareness and sale restrictions can we prevent the intentional and accidental poisoning caused by this easily available, highly toxic compound.

Acute liver failure secondary to the use of unmonitored drugs and herbal supplements: an underreported and serious issue.

Acute liver failure (ALF) is a potentially fatal illness marked by the abrupt development of jaundice, coagulopathy, and hepatic encephalopathy (HE) in persons having no previous history of hepatic disease. It is a relatively uncommon illness, having an incidence of 1 to 8 per million people. Hepatitis A, B, and E viruses have been documented as the most prevalent etiologies of acute liver failure in Pakistan and other developing nations. However, ALF may also occur secondary to toxicity caused by the unmonitored overdosing and toxicity of traditional medicines, herbal supplements, and alcohol. Similarly, in some instances, the etiology remains unknown. Herbal products, alternative, and complementary therapies are frequently practiced across the globe for treating various illnesses. In recent times, their use has gained much popularity. Indications and the use of these supplementary drugs vary significantly. The majority of these products have not gained approval from Food and Drug Administration (FDA). Unfortunately, the incidence of documented adverse effects linked to the usage of herbal products has increased recently, but still, these events are underreported, and the condition is known as drug-induced liver injury (DILI) and herb-induced liver injury (HILI). The estimated total herbal retail sales increased from $4230 million in 2000 to $6032 million in 2013, representing a total of 42 and 3.3% per annum increase. To reduce the occurrence of HILI and DILI, physicians in general practice settings should inquire about patients' understanding of potential toxicity with the consumption of hepatotoxic and herbal medicines.

Proceedings of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition Monothematic Conference, 2020: "Acute Liver Failure in Children": Treatment and Directions for Future Research.

OBJECTIVES: The Hepatology Committee of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) aims to educate pediatric gastroenterologists, members of ESPGHAN and professionals from other specialties promoting an exchange of clinical expertise in the field of pediatric hepatology. METHODS: The 2020 single topic ESPGHAN monothematic 3-day conference on pediatric liver disease, was organized in Athens, Greece and was entitled " Acute Liver Failure" (ALF). ALF is a devastating disease with high mortality and in a considerable fraction of patients, the cause remains unresolved. As knowledge in diagnosis and treatment of ALF in infants and children has increased in the past decades, the objective was to update physicians in the field with developments in medical therapy and indications for liver transplantation (LT) and to identify areas for future research in clinical and neurocognitive outcomes in ALF. RESULTS: We recently reported the epidemiology, diagnosis, and initial intensive care management issues in separate manuscript. Herewith we report on the medical treatment, clinical lessons arising from pediatric studies, nutritional and renal replacement therapy (RRT), indications and contraindications for LT, neurocognitive outcomes, new techniques used as bridging to LT, and areas for future research. Oral presentations by experts in various fields are summarized highlighting key learning points. CONCLUSIONS: The current report summarizes the current insights in medical treatment of pediatric ALF and the directions for future research.

Plasmapheresis in lethal yellow phosphorus poisoning: a scope for recovery.

A 16-year-old girl presented with grade 3 hepatic encephalopathy (HE) following suicide attempt after consuming a lethal dose of yellow phosphorus containing rodenticide. Although she was a candidate for liver transplantation, it could not be done. In the absence of a specific antidote for yellow phosphorus poisoning, the patient was managed conservatively. In addition, low volume-therapeutic plasma exchange (LV-TPE) was initiated, which resulted in a dramatic improvement in HE. Although liver transplantation is the definitive treatment, this case has shown that TPE has a promising role as a 'bridge to recovery' in situations where transplantation is not feasible. We describe our experience with the above-mentioned case, along with the sequence of clinical recovery and the trend in biochemical parameters during follow-up. The patient made a full recovery and is doing well.

Fulminant Wilson Disease in Children: Recovery After Plasma Exchange Without Transplantation.

OBJECTIVES: Since 2005, a New Wilson Index (NWI) ≥11 is used as a predictor of death without transplantation in fulminant Wilson disease (WD). Plasma exchange is advocated as a new treatment modality. METHODS: We present a patient with fulminant WD treated with plasma exchange. All published cases applying plasma exchange for fulminant WD were reviewed systematically. RESULTS: A 14-year-old girl presented with hemolysis and fulminant liver failure. She had no encephalopathy; NWI was 14. As a bridge to transplantation plasma exchange was started immediately. Complete remission was achieved with plasma exchange and later chelation therapy with D-penicillamine. She is now at 3-year transplant-free survival. Literature review identified 37 patients presenting with fulminant WD and NWI ≥11 who were treated with plasma exchange. Seventeen of these patients (ie, 46%) recovered without transplantation. CONCLUSIONS: Multiple case reports and case series demonstrate transplant free survival after plasma exchange and subsequent chelation therapy, despite a NWI ≥11. Plasma exchange affects the clinical course and is a therapeutic option in children and young adults presenting with fulminant WD.

Critical care management in patients with acute liver failure.

Acute liver failure (ALF) is defined as severe hepatic dysfunction (marked transaminases elevation, detoxification disorder (jaundice and coagulopathy with international normal ratio (INR) > 1.5), the presence of hepatic encephalopathy, and exclusion of underlying chronic liver disease, and a secondary cause like sepsis or cardiogenic shock. Reasons for ALF include paracetamol and warfarin toxicity, autoimmune and viral (mainly hepatitis B and E) hepatitis, and herbal and dietary supplements. Even in terms of meticulous and careful review of the patient, around 20-30% of the reasons remains unknown. In order of its rarity, a randomized controlled trial could hardly be done. However, because of improved ICU treatment, the mortality, even in the advanced stage of ALF decreased. However, in 5-10% of the cases an emergency transplantation is required. This justifies the treatment of this patient cohort in institutions that can provide this kind of treatment.

Acute Hepatic Failure and Nutrition.

Malnutrition is prevalent in patients with hepatic failure and remains an independent risk factor for morbidity and mortality in these patients. Factors that contribute to malnutrition in this patient population include altered metabolic rate, fat malabsorption, and impaired gastric emptying, all in the setting of an acute and potentially prolonged hospitalization. Acute liver failure (ALF), different from cirrhosis or chronic liver disease, is an uncommon but dramatic clinical syndrome that demonstrates severe and rapid decline in hepatic metabolic function. ALF has a significant risk of mortality. There are >10 cases per million persons per year in developed countries, but ALF presents with unique challenges in clinical management related to heterogeneity in severity and etiology. Patients with ALF by definition should not have a prior history of liver disease, and liver disease is subsequently defined by the onset of liver injury, the presence of hepatic encephalopathy (HE), and coagulopathy as defined by an international normalized ratio > 1.5. HE usually develops within 1-4 weeks of the onset of liver injury but may occur within 26 weeks of the initial presentation. Rates of survival from ALF have improved over recent years, but the rarity and severity of presentation have resulted in traditionally limited evidence to guide basic supportive care. Over time, advances in critical care management and the use of emergency liver transplantation have improved. In this article, we will review current nutrition considerations for patients with ALF.

A knack for "NAC": Treatment for heat stroke induced acute liver injury.

INTRODUCTION: Heat stroke occurs when the body's core temperature becomes elevated above 40 °C, which may impact multiple organ systems. We present a case of heat stroke resulting in acute liver injury (ALI) successfully treated with intravenous N-acetylcysteine (NAC). CASE PRESENTATION: A 24-year-old unresponsive male without significant past medical history presented to the emergency department with heat stroke; his initial temperature was 107.4 °F. During his hospital course, he developed ALI with significant elevation in aspartate aminotransferase, alanine aminotransferase, and total bilirubin. These laboratory findings peaked by hospital day two, but improved prior to discharge on hospital day five and throughout his follow up clinic visits. His treatment course included cooling measures, supportive care, supplemental oxygen and airway management, seizure control, and intravenous NAC therapy. CONCLUSION: Hepatocellular injury is one of the most serious complications of heat stroke. We discuss the incidence and outcomes for patients who develop acute liver injury secondary to heat stroke and the use of NAC as an early potential therapeutic option.

Role of therapeutic plasma exchange in acute liver failure due to yellow phosphorus poisoning.

BACKGROUND: Therapeutic plasma exchange (TPE) has been utilized in various liver disorders. There is limited data on the efficacy of TPE in patients with acute liver failure (ALF). METHODS: Study group consisted of patients who underwent TPE for ALF due to yellow phosphorous poisoning (YPP) between 2015 and 2019. Demographic data and biochemical parameters were recorded before and after TPE. Overall survival and transplant-free survival (based on King's College Hospital Criteria [KCHC]) were analyzed. RESULTS: Forty-three patients underwent TPE for ALF due to YPP. Most of them were young males. Overall survival was 34 (79.06%). In our study population, 20 patients fulfilled KCHC (Group A) and 23 did not fulfill KCHC (Group B). Both the groups showed significant improvement in alanine aminotransferase, aspartate aminotransferase, and international normalized ratio (INR) after TPE (p < 0.05). In Group B, there was significant improvement in ammonia after TPE (p < 0.05) and all 23 patients (100%) survived after TPE. In Group A, 4 underwent liver transplantation (LT), 7 survived without LT, and the remaining 9 died without LT. Mean survival after completing TPE was 41.2 ± 44.5 days in Group A and 90 days in Group B. This difference was statistically significant (p = 0.001). There was statistically significant difference in post-TPE values of INR (p = 0.012) and ammonia (p = 0.011) between non-survivors and survivors. Adverse events such as hypotension (11.62%) and minor allergic reaction (4.65%) were managed conservatively. CONCLUSION: TPE is an effective procedure in ALF due to YPP, not fulfilling KCHC for LT. In KCHC fulfilled group, though it shows LT-free survival benefit, there is requirement of prospective, large volume, multi-center study to assess its efficacy.

[Treatment of Fulminant Hepatic Failure - Myth and Facts]. / Die Therapie des akuten Leberversagens ­ alte Mythen und neue Trends.

Acute liver failure (ALF) refers to primary damage to a previously healthy liver. It is a rare disease with an incidence of about 200-500 cases/year in Germany. The liver can recover to restitutio ad integrum or lead to death in no time despite best medical treatment. Due to the rarity and potentially dramatic clinical course, patients with acute liver failure should be promptly referred to a special liver unit that can provide a liver transplantation as rescue treatment.The ALF should be strictly distinguished from "acute-on-chronic" liver failure (ACLF), which may show a similar clinical course but does not qualify for a high-urgency listing and transplantation.The reason for an ALF remains unknown in up to 20 % of cases. Hepatotropic virus (HAV, HBV and HEV) are the most common causative agents in Africa and Asia, while in North America and Northern and Central Europe, more drug-related liver failure is more frequent. Among drugs paracetamol and phenprocoumone are the leading cause for ALF. However, there are a couple of dietary supplements, herbs and mushroom poisoning that cause ALF.Other reasons are ischemic hepatitis and autoimmune hepatitis.

Neonatal Acute Liver Failure Associated with Angioinvasive Hepatic Zygomycosis.

BACKGROUND: Neonatal acute liver failure (NALF) is often a fatal condition. Zygomycosis is a fungal infection that is often fatal in both adults and infants. Only a few cases of hepatic zygomycosis are reported in the literature and they are invariably associated with immunosuppression. MATERIALS AND METHODS: Post-mortem liver biopsy from a 14-day old neonate demonstrated confluent panacinar necrosis with angioinvasive zygomycosis. The limited work-up could not rule out an underlying immunodeficiency. CONCLUSION: Angioinvasive hepatic zygomycosis can present in the neonatal period as NALF.

Liver transplantation and the use of KAVA: Case report.

BACKGROUND: Self-medication and the belief that herbal products are free of health risks are common in Brazil. The kava (Piper methysticum), known for its anxiolytic action, has a widespread popular use. Hepatotoxicity of kava is reported, including cases of liver transplantation and death. The kava had its use prohibited or restricted in countries like Germany, France, among others. Toxicity may be related to overdosage; however, factors such as botanical characteristics of the plant, the harvesting, storage, and production process may be associated with the development of hepatotoxic substances, such as triggering idiosyncratic reactions. HYPOTHESIS: In this case, there is a suspicion that the toxicide is intrinsic to the drug; however, the possibility of adulterants and contaminants must be ruled out. STUDY DESIGN: This study reports the case of a patient who, after using the herbal kava for 52 days, evolved into acute liver failure and liver transplantation. METHODS: The data were collected directly with the patient and compared with their clinical records. Causality was determined through the RUCAM algorithm. In addition, a phytochemical analysis of the drug used was performed. RESULTS: According to the patient's report, there is no evidence of overdosage. Results from RUCAM algorithm infer causality between liver damage and the use of kava. The analysis chemical constituents did not find any possible contaminants and major changes in the active compounds. Seven months after transplantation, the patient is well and continues to be followed up by a medical team. CONCLUSION: Our investigation indicates that there was kava-induced hepatotoxicity at standard dosages. In Brazil, self-medication by herbal medicines is frequent and many patients and health professionals do not know the risks associated with their use. Diagnosing and notifying cases in which plants and herbal medicine induce liver damage is of paramount importance to increase the knowledge about DILI and to prevent or treat similar cases quickly.

Plasmapheresis Combined with Continuous Plasma Filtration Adsorption Rescues Severe Acute Liver Failure in Wilson's Disease before Liver Transplantation.

Wilsonian crisis (hemolytic crisis and acute liver failure [ALF] in Wilson's disease) is fatal and almost all patients ultimately need a timely liver transplantation to save their lives. How to safely pass the critical period to liver transplantation is still a big challenge to doctors especially to pediatricians facing more difficult situations in blood purification. Here, we report about a 7-year-old child (weight 21 kg) presenting with severe hemolysis and impending ALF that made a rapid recovery with prompt initiation of plasmapheresis combined with continuous plasma filtration adsorption (CPFA) and chelation therapy. Rapidly efficient removal of copper, bilirubin, and albumin-binding toxins by hybrid blood purification alleviated hemolysis and liver injury and successfully bridged the patient over the critical period to late liver transplantation. Moreover, a review of the literature was performed examining the use of plasmapheresis, molecular adsorbent recirculation system, single-pass albumin dialysis, and continuous veno-venous hemodiafiltration in Wilson disease. The experience of our case points to that plasmapheresis combined with CPFA treatment can improve clinical symptoms and bridge children over through Wilsonian crisis to late live transplantation, and CPFA treatment is feasible and safe in children weighing more than 20 kg.

Liver Injury Associated with Sporting Activities.

Exertional heat stroke most commonly develops following prolonged levels of aerobic activity in a warm or humid environment. Hypoperfusion of the vital organs along with activation of the inflammasome can lead to progressive and potentially fatal multiorgan failure including acute liver failure. In the United States, herbal and dietary supplements that are marketed to improve performance, strength, and weight loss are increasingly being used by both amateur and professional athletes. Consumption of bodybuilding supplements that contain androgenic anabolic steroids can lead to adverse hepatic effects ranging from asymptomatic serum aminotransferase elevations to severe cholestatic hepatitis with prolonged jaundice. Various non-bodybuilding nutritional supplements that contain a mixture of botanicals, caffeine, and chemicals have also been associated with idiosyncratic hepatotoxicity. In particular, green tea extract derivatives that contain epigallocatechin gallate are hepatotoxic in animal models and have been associated with severe acute hepatocellular injury in humans.

Aerobic training and L-arginine supplement attenuates myocardial infarction-induced kidney and liver injury in rats via reduced oxidative stress.

INTRODUCTION: The aim of the present study was to determine the effect of exercise training and l-arginine supplementation on kidney and liver injury in rats with myocardial infarction (MI). MATERIAL AND METHODS: Four weeks after MI, 50 male wistar rats randomly divided into five followed groups: sham surgery without MI (Sham, n=10), Sedentary-MI (Sed-MI, n=10) 3: L-Arginine-MI (La-MI, n=10) 4: Exercise training-MI (Ex-MI, n=10) and 5: Exercise and L-arginine-MI (Ex+La-MI). Ex-MI and Ex+La-MI groups running on a treadmill for 10 weeks with moderate intensity. Rats in the L-arginine-treated groups drank water containing 4% L-arginine. Tissues oxidative stress and kidney and liver functional indices were measured after treatments. RESULT: Urea as a kidney function indexes, increased in Sed-MI group in compared to sham group and decreased significantly in Ex-MI and Ex+La-MI groups. The level of catalase (CAT) and glutathione stimulating hormone (GSH) of kidney were significantly lower in the MI-groups compared with the Sham group and kidney Malondialdehyde (MDA) levels increased after MI and significantly decreased in response to aerobic training and L-arginine. As well as, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) as liver injury indices, increased in MI-groups and decreased by training and L-arginine. In this regards, liver MDA and CAT respectively increased and decreased in MI-groups, but aerobic training and L-arginine increased liver glutathione per-oxidase (GPx) and decreased liver MDA. CONCLUSION: These results demonstrated that kidney and liver function impaired 14 weeks after MI and aerobic training and L-arginine supplementation synergistically ameliorated kidneys and liver injury in myocardial infarction rats through oxidative stress reduction.
