RESUMEN

We present the case of a 58-year-old female patient who presented with an extramedullary B-ALL relapse after prior allogenic HSCT and blinatumomab therapy. The patient died from complications of a drug-induced acute liver failure after a salvage therapy combining inotuzumab ozogamicin (InO)-based induction followed by consolidation with high dose MTX and pegaspargase based on the GMALL protocol for older ALL patients. After a diagnosis of the extramedullary relapse in the form of a retro vesical chloroma, the patient received an individualized multi-agent chemotherapy based on induction chemotherapy for older patients in combination with InO. After four administrations of InO, in combination with vincristine, dexamethasone, cytarabine, and cyclophosphamide, CT-imaging showed a reduction in volume of the chloroma and response to therapy. Consolidation with high-dose methotrexate and pegaspargase was administered. The patient developed toxic liver damage manifested by hyperbilirubinemia and progressive hepatic encephalopathy. The diagnostic criteria for VOD were met, and therapy with defibrotide was initiated. Liver biopsy revealed no histological signs of VOD but instead steatohepatitis indicative of drug-induced toxicity. The patient ultimately died of hemorrhagic shock through postinterventional hemorrhage after liver biopsy. In conclusion, although InO shows promising results in the therapy of r/r ALL with and without additional chemotherapy, the combination with MTX and pegaspargase in an intensively pretreated patient with relapse after HCST may impart an increased risk for liver-related toxicity. Special caution is required when assessing fitness for further liver toxic regimens. A key takeaway is also the reminder that InO can cause liver damage not only in the form of VOD but also through direct hepatocellular toxicity.

RESUMEN

Acetaminophen is generally regarded as a safe antipyretic and analgetic agent and is widely used in cases of pregnancy. However, acetaminophen is also one of the most frequently reported medications in cases of drug overdose. On the other hand, in the few instances described in the literature, where normal doses of acetaminophen administered during pregnancy may have had a fatal outcome, evidence existed pointing to a history of liver disease. It is therefore of interest that the patient in this report who died of liver failure after ingesting standard doses of acetaminophen also suffered from intrahepatic cholestasis during pregnancy although there was no history of liver disease. Other than these instances, there have been no previous reports in the literature of a normal, therapeutic dose of acetaminophen having a fatal outcome in pregnancy. This case emphasizes the need for caution when prescribing acetaminophen during pregnancy to patients with a history of liver disease, regardless of whether the liver function has returned to normal.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Triazole antifungal-associated severe skin allergy has received little attention. Here we report a case of an acute-on-chronic liver failure (ACLF) patient with diffused skin allergy pervading from the chest, abdomen, back, knees to perineum, with red colour and partially desquamation as well as a neurological adverse (insomnia) event after voriconazole treatment. CASE SUMMARY: A 40-year-old man with liver failure in our hospital had received voriconazole for invasive fungal infection therapy, and while waiting for liver transplantation exhibited a severe diffuse rash and a neurological adverse event. WHAT IS NEW AND CONCLUSION: To the best of our knowledge, this is the first report of a liver failure patient who suffered a severe allergy accompanied with a neurological adverse event after voriconazole administration.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: We present a case of intravenous amiodarone-induced liver injury, pharmacy monitoring and its therapy. CASE SUMMARY: A 76-year-old male patient developed acute liver injury 24 h after starting intravenous amiodarone. His liver enzymes improved after discontinuing amiodarone and anti-inflammatory liver therapy, which used reduced glutathione, magnesium isoglycyrrhizinate and ademetionine1,4-butanedisulfonate for injection. WHAT IS NEW AND CONCLUSION: Amiodarone is a highly effective antiarrhythmic agent for the treatment and prevention of atrial and ventricular arrhythmias. Acute liver damage after intravenous amiodarone is rare but potentially harmful. Amiodarone loading should be adapted to the necessity of an immediate effect of the drug, and liver function should be monitored closely in critically ill patients. Timely stopped suspected drug and anti-inflammatory liver therapy may reduce the occurrence of drug-induced diseases.

RESUMEN

Regional citrate anticoagulation (RCA) is an option but citrate accumulation is risk and it is a giving up cause for this situation. This retrospective study was conducted in the pediatric intensive care unit (PICU) between May 2019 and April 2021. We investigated 47 patients with liver failure (LF) in our PICU, and RCA during continuous renal replacement therapy (CRRT) was applied to 10 (21.3%) of them. Half of them were male (n: 5/10), their mean age was 104.7 ± 66.20 months. Nine of them needed vasoactive support during follow-up. The most common indication for CRRT was hepatorenal syndrome (40%). There was no significant difference between liver transaminases and liver function tests before and after CRRT (p > 0.05). In terms of citrate toxicity of the patients, there was no significant difference between total calcium/ionized calcium, lactate level, pH and bicarbonate values before and after CRRT (p > 0.05). The mean total CRRT time was 110.2 ± 118.2 h, and the mean circuit lifespan was 43.8 ± 48.7 h; the mean number of circuits was 2.7 ± 2.4. Total Ca/ionized Ca >2.5 was a clinically relevant endpoint, but no patient interrupted dialysis for this cause. There was no complication about RCA. This study did not observe any adverse effects on acid-base status, transaminases, an increase in bilirubin during RCA-CRRT treatment in pediatric patients with LF. Total calcium/ionized calcium ratio, serum lactate level and prothrombin time level should be closely monitored daily in terms of citrate accumulation in this patient group.

RESUMEN

The use of over-the-Counter (OTC) pharmaceuticals is a common phenomenon in today's society. We present a case of liver injury associated with long-term OTC use of vitamin A. The young patient took daily up to 15 capsules of a combined preparation for 2 years containing retinol palmitate 55 mg (100,000 IU) + Alpha-Tocopherol acetate 100 mg, the content of vitamin A in which significantly exceeded the recommended daily dose. Gradually, the patient noted the appearance of arthralgia, skin itching, hyperemia of the palms and feet, exfoliation of the skin on the soles, profuse hair loss, cracks in the corners of the mouth and in the area of the earlobes. Patient's condition worsened with the development of signs of liver cirrhosis in the form of portal hypertension (ascites, splenomegaly) and a decrease in the protein-synthetic function of the organ. Chronic viral hepatitis, autoimmune hepatitis, primary biliary cirrhosis, hemochromatosis, Wilson's disease, alcoholic liver disease were exclude. Liver biopsy showed characteristic signs of hypervitaminosis A without fibrosis. A complete regression of symptoms was observe within 8 months after discontinuation of the drug. A toxicity can lead to serious liver injury and should be considere in the differential diagnosis of chronic liver disease. Vitamin A should only be prescribe for medical reasons, for a limited period of time, and under close medical supervision.

RESUMEN

This study aimed to investigate the therapeutic potential of human umbilical cord mesenchymal stem cells derived exosomes (hUCMSC-Exo) in acute liver failure (ALF) in mice as well as its underlying mechanism. We found that a single tail vein administration of hucMSC-Exo effectively enhanced the survival rate, inhibited apoptosis in hepatocytes, and improved liver function in APAP-induced mouse model of ALF. Furthermore, the deletion of glutathione (GSH) and superoxide dismutase (SOD), generation of malondialdehyde (MDA), and the over production of cytochrome P450 E1 (CYP2E1) and 4-hydroxynonenal (4-HNE) caused by APAP were also inhibited by hucMSC-Exo, indicating that hucMSC-Exo inhibited APAP-induced apoptosis of hepatocytes by reducing oxidative stress. Moreover, hucMSC-Exo significantly down-regulated the levels of inflammatory cytokines IL-6, IL-1ß, and TNF-α in APAP-treated livers. Western blot showed that hucMSC-Exo significantly promoted the activation of ERK1/2 and IGF-1R/PI3K/AKT signaling pathways in APAP-injured LO2 cells, resulting in the inhibition of apoptosis of LO2 cells. Importantly, PI3K inhibitor LY294002 and ERK1/2 inhibitor PD98059 could reverse the function of hucMSC-Exo on APAP-injured LO2 cells in some extent. Our results suggest that hucMSC-Exo offer antioxidant hepatoprotection against APAP in vitro and in vivo by inhibitiing oxidative stress-induced apoptosis via upregulation of ERK1/2 and PI3K/AKT signaling pathways.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Anaplastic Lymphoma Kinase Tyrosine Kinase Inhibitors (ALK TKIs) are standard first-line therapy for non-small cell lung cancer patients with ALK rearrangement. Although some cases of hepatotoxicity related to these drugs have been reported, there is still a lack of investigation on severe hepatotoxicity, such as hepatic failure, with ALK TKIs. METHODS: We evaluated ALK TKI (crizotinib, alectinib, brigatinib, ceritinib and lorlatinib)-induced hepatic failure events (AIHFEs), by using the Reporting Odds Ratio (ROR) and Bayesian Confidence Propagation Neural Network method for mining the adverse event report signals in the FDA Adverse Event Reporting System (FAERS) database from Jan 2013 to Dec 2019. RESULTS AND DISCUSSION: The AIHFEs of "Hepatic failure," "hepatitis fulminant" and "hepatic necrosis" were defined as exposure event signals caused by ALK TKIs. The RORs of "Hepatic failure" were 4.95 (2.36-10.42) in alectinib, 3.77 (1.69-8.40) in ceritinib and 2.45 (1.60-3.76) in crizotinib, respectively. The ROR of "hepatitis fulminant" was 7.86 (3.52-17.54) in crizotinib. The Information Component value of "hepatic necrosis" was 1.97 (0.15) in alectinib. In reports of exposure-event signals, the clinical outcome of eventual death was common and could occur within 3 months. In the reports of "hepatic failure," there was no significant difference in the number of reports between men and women [OR=1.86 (0.94-3.67), p = 0.09]. WHAT IS NEW AND CONCLUSIONS: By mining the adverse event report signals in the FAERS database, we found the exposure event signals of AIHFEs in ALK TKIs were "hepatic failure," "hepatitis fulminant" and "hepatic necrosis". AIHFEs were more likely to appear in the reports of ceritinib, crizotinib and alectinib.

RESUMEN

BACKGROUND: High demand for HIV-services and extensive clinical guidelines force health systems in low-resource settings to dedicate resources to service delivery at the expense of other priorities. Simplifying services may reduce the burden on health systems and pre-antiretroviral therapy (ART) laboratory screening is among the services under consideration for simplification. METHODS: We assessed the frequencies of conditions linked to ART toxicities among 34,994 adult, ART-naïve patients with specimens referred to the RETRO-CI laboratory in Abidjan, Côte d'Ivoire between 1998 and 2017. Screening included tests for serum creatinine, alanine aminotransferase (ALT) and haemoglobin (Hb) to identify renal dysfunction (estimated glomerular filtration rate < 50 mL/min), hepatic abnormalities (ALT > 5× upper limit of normal) and severe anaemia (Hb < 6.5 g/dL), respectively. We considered screening results across four eras and identified factors associated with the conditions in question. RESULTS: The prevalence of renal dysfunction, hepatic abnormalities and severe anaemia were largely unchanged over time and just 8.4% of patients had any of the three conditions. Key factors associated with renal dysfunction and severe anaemia were age > 50 years (adjusted odds ratio (aOR): 2.53; 95% confidence interval (CI): 2.19-2.92; P < 0.001) and CD4 < 100 cells/µl (aOR: 2.57; 95% CI: 2.30-2.88; P < 0.001). CONCLUSION: The relative infrequency of conditions linked to toxicity in Côte d'Ivoire supports the notion that simplification of pre-ART laboratory screening may be undertaken with limited negative impact on identification of adverse events. Targeted screening may be a feasible strategy to balance detection of conditions associated with ART toxicities with simplification of services.


CONTEXTE: La forte demande de services VIH et les directives cliniques détaillées obligent les systèmes de santé des pays à faibles ressources à consacrer des ressources à la prestation de services au détriment d'autres priorités. La simplification des services peut réduire la charge pesant sur les systèmes de santé et les analyses de laboratoire avant la thérapie antirétrovirale (ART) fait partie des services envisagés pour la simplification. MÉTHODES: Nous avons évalué la fréquence des conditions liées aux toxicités dues à l'ART chez 34.994 patients adultes naïfs pour l'ART avec des échantillons référés au laboratoire RETRO-CI à Abidjan, en Côte d'Ivoire entre 1998 et 2017. Les analyses comprenaient les tests de créatinine sérique, d'alanine aminotransférase (ALT) et d'hémoglobine (Hb) pour identifier respectivement la dysfonction rénale (débit de filtration glomérulaire estimé <50 mL/min), les anomalies hépatiques (ALT >5x la limite supérieure normale) et l'anémie sévère (Hb <6,5 g/dL). Nous avons examiné les résultats des analyses sur quatre époques et identifié les conditions associées aux conditions en question. RÉSULTATS: La prévalence de la dysfonction rénale, des anomalies hépatiques et de l'anémie sévère est restée largement inchangée au fil du temps et seulement 8,4% des patients présentaient l'une des trois conditions. Les facteurs clés associés à la dysfonction rénale et à l'anémie sévère étaient l'âge >50 ans (odds ratio ajusté (aOR): 2,53; intervalle de confiance (IC) à 95%: 2,19 à 2,92; p <0,001) et les CD4 <100 cellules/µl (aOR: 2,57; IC95%: 2,30 à 2,88; P < 0,001). CONCLUSION: La relativement faible fréquence des conditions liées à la toxicité en Côte d'Ivoire soutient la notion selon laquelle une simplification des analyses de laboratoire pré-ART peut être entreprise avec un impact négatif limité sur l'identification des événements adverses. Le ciblage des analyses peut être une stratégie réalisable pour aligner la détection des conditions associées aux toxicités ART à la simplification des services.

RESUMEN

Transaldolase (TAL) is an enzyme in the pentose phosphate pathway (PPP) that generates NADPH for protection against oxidative stress. While deficiency of other PPP enzymes, such as transketolase (TKT), are incompatible with mammalian cell survival, mice lacking TAL are viable and develop progressive liver disease attributed to oxidative stress. Mice with homozygous or heterozygous TAL deficiency are predisposed to cirrhosis, hepatocellular carcinoma (HCC) and acetaminophen (APAP)-induced liver failure. Both mice and humans with complete TAL deficiency accumulate sedoheptulose 7-phosphate (S7P). Previous human studies relied on screening patients with S7P accumulation, thus excluding potentially pathogenic haploinsufficiency. Of note, mice with TAL haploinsufficiency are also predisposed to HCC and APAP-induced liver failure which are preventable with oral N-acetylcysteine (NAC) administration. Based on TALDO1 DNA sequencing, we detected functional TAL deficiency due to novel, heterozygous variations in two of 94 healthy adults and four of 27 subjects with APAP-induced liver failure (P = .022). The functional consequences of these variations were individually validated by site-directed mutagenesis of normal cDNA and loss of activity by recombinant enzyme. All four patients with TAL haplo-insufficiency with APAP-induced liver failure were successfully treated with NAC. We also document two novel variations in two of 15 children with previously unexplained liver cirrhosis. Examination of the National Center for Biotechnology Information databases revealed 274 coding region variations have been documented in 1125 TALDO1 sequences relative to 25 variations in 2870 TKT sequences (P < .0001). These findings suggest an unexpected prevalence and variety of genetic changes in human TALDO1 with relevance for liver injury that may be preventable by treatment with NAC.

RESUMEN

This study aims to investigate how microRNA-375 (miR-375) improves immune function by regulating liver macrophages (Kupffer cells) in mice with liver failure. Forty mice were divided into ConA-1h, ConA-3h, ConA-6h, and control groups, with 10 mice in each group. Mice models of liver failure were established by injecting concanavalin A (ConA) solution via the tail veins of mice, and then primary Kupffer cells were isolated and cultured. Reverse transcription quantitative polymerase chain reaction, Western blot analysis, and enzyme-linked immunosorbent assay were conducted to examine the expressions of miR-375, astrocyte elevated gene-1 (AEG-1), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-1ß in Kupffer cells of mice with liver failure as well as after silencing of miR-375. Flow cytometry was used to determine cell apoptosis. During the liver failure process, miR-375, IL-6, TNF-α, and IL-1ß expressions were increased over time, while AEG-1 expression decreased over time in the control, ConA-1h, ConA-3h, and ConA-6h groups. Opposite alternations were observed after silencing of miR-375. Dual-luciferase reporter gene assay showed that AEG-1 was a target gene of miR-375. Flow cytometry determination showed that the ratio of apoptotic Kupffer cells decreased after silencing of miR-375. Overexpression of AEG-1 could rescue the suppression of IL-6, TNF-α, and IL-1ß expressions in Kupffer cells after the short-term induction of ConA and further inhibit cell apoptosis. Our study provides evidence that miR-375 could regulate Kupffer cells to improve immune function in mice with liver failure.

RESUMEN

BACKGROUND & AIMS: Polygonum Multiflorum Thumb (PMT), an ancient anti-aging Chinese herb known traditionally as He Shou Wu, has side effects of liver toxicity. To determine the main clinical and pathological characteristics of liver toxicity induced by PMT and the clinical course after its cessation. METHODS: Data of patients, diagnosed as drug-induced liver injury and hospitalised in Beijing Friendship Hospital from August 2005 to August 2017, were retrospectively reviewed. Clinical, pathological data and outcome after cessation of He Shou Wu were obtained and analysed. Kruskal-Wallis and Chi-square (χ2 ) tests were performed. RESULTS: Twenty-nine patients with He Shou Wu-induced liver injury were enrolled. The median age was 53 years (range 15-74) and 75.9% (22/29) were women. The most common symptom was jaundice (79.3%, 23/29). Of nine patients with liver biopsies, six showed acute cholestatic hepatitis, two acute, and one chronic hepatocellular injury pattern. The latency, liver chemistries and outcomes were comparable between pure He Shou Wu (5 patients) and its compounds (24 patients). Twenty-five of 29 patients (86.2%) had normal serum alanine aminotransferase levels after 45 days (range: 10-138 days) and total bilirubin of 46 days (range: 0-551 days). One patient was rechallenged with He Shou Wu and two developed autoimmune features. One patient died of liver failure and three had chronic persistent liver injury. CONCLUSIONS: The main clinicopathological injury pattern of He Shou Wu-induced liver injury is moderate to severe hepatitis with or without cholestasis. Most patients recover completely; however, chronic disease and death do occur.

RESUMEN

A clinical case in Belgium demonstrated that feeding a feed concentrate containing considerable levels of deoxynivalenol (DON, 1.13 mg/kg feed) induced severe liver failure in 2- to 3-month-old beef calves. Symptoms disappeared by replacing the highly contaminated corn and by stimulating ruminal development via roughage administration. A multi-mycotoxin contamination was demonstrated in feed samples collected at 15 different veal farms in Belgium. DON was most prevalent, contaminating 80% of the roughage samples (mixed straw and maize silage; average concentration in positives: 637 ± 621 µg/kg, max. 1818 µg/kg), and all feed concentrate samples (411 ± 156 µg/kg, max. 693 µg/kg). In order to evaluate the impact of roughage provision and its associated ruminal development on the gastro-intestinal absorption and biodegradation of DON and its acetylated derivatives (3- and 15-ADON) in calves, a toxicokinetic study was performed with two ruminating and two non-ruminating male calves. Animals received in succession a bolus of DON (120 µg/kg bodyweight (BW)), 15-ADON (50 µg/kg BW), and 3-ADON (25 µg/kg) by intravenous (IV) injection or per os (PO) in a cross-over design. The absolute oral bioavailability of DON was much higher in non-ruminating calves (50.7 ± 33.0%) compared to ruminating calves (4.1 ± 4.5%). Immediately following exposure, 3- and 15-ADON were hydrolysed to DON in ruminating calves. DON and its acetylated metabolites were mainly metabolized to DON-3-glucuronide, however, also small amounts of DON-15-glucuronide were detected in urine. DON degradation to deepoxy-DON (DOM-1) was only observed to a relevant extent in ruminating calves. Consequently, toxicity of DON in calves is closely related to roughage provision and the associated stage of ruminal development.

RESUMEN

Cudratricusxanthone A (CTXA), a natural bioactive compound extracted from the roots of Cudraniatricuspidata Bureau, is known to possess antithrombotic, antiproliferative, and antiinflammatory activities. It remains unclear that CTXA can improve hepatoprotective activity in vivo. The objective of this study was to investigate the effect of CTXA on lipopolysaccharide (LPS)-induced liver failure in mice, and to elucidate its underlying molecular mechanisms. Liver failure was induced by LPS (15 mg/kg, i.p.) in mice, and 12 hr later, they were treated intravenously with CTXA. Administration of LPS significantly increased mortality, serum levels of alanine transaminase (ALT), aspartate transaminase (AST), and serum inflammatory cytokines. CTXA treatment effectively countered these effects of LPS. Further, LPS treatment markedly increased the expression of myeloperoxidase, phosphorylation of p38, extracellular signal-regulated kinase (ERK), and c-Jun N-terminal kinase (JNK), and expressions of nuclear proteins, such as nuclear factor (NF)-κB and phosphorylated c-Jun. Additionally, LPS increased the serum levels of tumor necrosis factor (TNF)-α and interleukin (IL)-6. All these effects of LPS were attenuated by CTXA. Moreover, CTXA increased the expression of sirtuin-1 (SIRT1) and reduced the expression of acetylated forkhead box O1 box O1 (Ac-FoxO1), acetylated Ac-p53, and acetylated nuclear factor-kappa beta (Ac-NF-κB). In conclusion, CTXA alleviates LPS-induced liver injury by reducing inflammatory responses and the potential mechanism is associated with SIRT1 signaling activation and finally could be used to treat liver diseases.

RESUMEN

OBJECTIVE: To explore the prognostic factors for patients with drug-induced liver failure (DILF) and construct a logistic regression model (LRM).
 Methods: A retrospective analysis of clinical data was performed in 183 hospitalized patients, who were diagnosed with DILF in Xiangya Hospital, the Second Xiangya Hospital and the Third Xiangya Hospital, Central South University from January 2009 to January 2018. The patients were divided into an improved group (n=67) and an ineffective group (n=116) according to their prognosis. Univariate analysis was performed to screen for possible prognostic factors such as age, Tbil, SCr, PT and complications. According to the results of univariate analysis, the multivariate analysis was performed to determine the independent prognostic factors and construct a LRM. The LRM was compared with the model for end-stage liver disease (MELD), the predictive value of LRM and MELD was evaluated by receiver operating characteristic curve (ROC), the parameters such as area under the ROC (AUC) and total accuracy were compared between the 2 models and verified by another independent sample.
 Results: According to univariate analysis, there was significant differences in age, clinical type, hepatic encephalopathy, hepatorenal syndrome, WBC count, the ratio of aspartic acid transaminase (AST) to glutamine transaminase (ALT) (AST/ALT), Tbil, SCr, PT and alpha-fetoprotein (AFP) between the 2 groups (all P<0.05). Multivariate analysis revealed that: AFP, PT, AST/ALT, hepatic encephalopathy and hepatorenal syndrome were independent prognostic factors for DILF, which could be applied to constructing a LRM. The AUC of LRM and MELD was 0.917 (95% CI 0.876 to 0.959) and 0.709 (95% CI 0.633 to 0.786) respectively, the total accuracy rate of prediction for the LRM and the MELD was 86.7% and 68.3% respectively, there was significant difference in AUC and total accuracy rate between the LRM and the MELD (P<0.05). LRM was superior to MELD.
 Conclusion: AFP, PT, AST/ALT, hepatic encephalopathy and hepatorenal syndrome were independent prognostic factors for DILF; the LRM can well predict the prognosis in the DILF patients, which is superior to the MELD.

RESUMEN

BACKGROUND: One of the major adverse events of caspofungin and micafungin is hepatotoxicity, however, there are few reports compared the incidence of hepatotoxicity between caspofungin and micafungin. Herein, the primary objective of this study was to compare the incidence of hepatotoxicity between caspofungin and micafungin treatments for patients with fungal or suspected fungal infection. METHODS: In total, 201 patients [caspofungin group: 66 patients; micafungin group: 135 patients] treated with echinocandins from April 2014 to November 2015 at Aichi Medical University Hospital. Investigation item were as follows; sex, age, weight, height, duration of treatment, total dose, disease type, clinical isolates, liver enzyme levels, concomitant medications. Liver function was assessed in accordance with Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0. We divided into two groups depend on their liver enzyme levels before treated with echinocandins; normal group (liver enzyme levels ≤ CTCAE Grade 1), abnormal group (liver enzyme levels ≥ CTCAE Grade 2). RESULTS: The overall incidence of serious hepatotoxicity (Grade 3 or higher) was 6.1% (4/66) in the caspofungin group and 7.4% (10/135) in the micafungin group. The proportion of patients used caspofungin and micafungin showed serious hepatotoxicity were 0% (0/47) and 6.5% (7/108) in normal group (p = 0.17), and 21.1% (4/19) and 10.7% (3/28) in abnormal group (p = 0.42). CONCLUSION: There was no notable difference in serious hepatotoxicity between the caspofungin group and the micafungin group, even though in patients with abnormal liver enzyme levels (CTCAE grade 2 or higher).

RESUMEN

Cerebral oxidative stress (OS) contributes to the pathogenesis of hepatic encephalopathy (HE). Existing evidence suggests that systemic administration of L-histidine (His) attenuates OS in brain of HE animal models, but the underlying mechanism is complex and not sufficiently understood. Here we tested the hypothesis that dipeptide carnosine (ß-alanyl-L-histidine, Car) may be neuroprotective in thioacetamide (TAA)-induced liver failure in rats and that, being His metabolite, may mediate the well documented anti-OS activity of His. Amino acids [His or Car (100 mg/kg)] were administrated 2 h before TAA (i.p., 300 mg/kg 3× in 24 h intervals) injection into Sprague-Dawley rats. The animals were thus tested for: (i) brain prefrontal cortex and blood contents of Car and His, (ii) amount of reactive oxygen species (ROS), total antioxidant capacity (TAC), GSSG/GSH ratio and thioredoxin reductase (TRx) activity, and (iii) behavioral changes (several models were used, i.e. tests for reflexes, open field, grip test, Rotarod). Brain level of Car was reduced in TAA rats, and His administration significantly elevated Car levels in control and TAA rats. Car partly attenuated TAA-induced ROS production and reduced GSH/GSSG ratio, whereas the increase of TRx activity in TAA brain was not significantly modulated by Car. Further, Car improved TAA-affected behavioral functions in rats, as was shown by the tests of righting and postural reflexes. Collectively, the results support the hypothesis that (i) Car may be added to the list of neuroprotective compounds of therapeutic potential on HE and that (ii) Car mediates at least a portion of the OS-attenuating activity of His in the setting of TAA-induced liver failure.

RESUMEN

BACKGROUND: "Bath salts" or synthetic cathinone toxicity remains a potentially deadly clinical condition. We report a delayed leukoencephalopathy with persistent minimally conscious state. METHODS: Case report. RESULTS: A 36-year-old man presents with delayed encephalopathy, dysautonomia, fulminant hepatic failure, and renal failure from severe rhabdomyolysis after consuming bath salts. MRI showed diffusion restriction in the splenium of the corpus callosum and subcortical white matter. CONCLUSIONS: The combination of acute leukoencephalopathy, rhabdomyolysis and fulminant hepatic failure may point to bath salt inhalation and should be known to neurointensivists.

RESUMEN

Compensatory tissue repair (CTR) in thioacetamide (TA)-primed rats protects them against acetaminophen (APAP)-induced lethality. This study was aimed at investigating the mechanisms of CTR-mediated heteroprotection in mice. Male Swiss Webster mice received a priming dose of TA (40 mg/kg body weight [BW] in 10 mL distilled water [DW]/kg BW, intraperitoneally [IP]). Thioacetamide-induced liver injury, CTR, and expression of annexin A1 and A2 (ANX1 and ANX2), the endogenous inhibitors of the death protein secretory phospholipase A2 (sPLA2), were measured over a time course of 84 hours after TA priming. Both centrilobular necrosis and CTR peaked at 36 hours after TA priming as indicated by significantly increased plasma alanine transaminase (ALT) and aspartate transaminase (AST) activities, liver histology, and proliferating cell nuclear antigen immunostaining. Thioacetamide priming resulted in the overexpression of ANX1 and ANX2 at 36 to 84 hours and 12 to 60 hours, respectively. A lethal dose of APAP (600 mg/kg BW in 10 mL 0.45% NaCl/kg BW, IP) was given at 12, 24, or 36 hours after TA-priming. Thioacetamide priming did not affect the rise in plasma ALT, AST, sPLA2, and arachidonic acid levels seen at 2 hours after the APAP overdose. Neither these biochemical parameters nor histology suggested any escalation of hepatic injury at later time points (12 and 24 hours after APAP overdose), consistent with 100% survival of the TA + APAP-treated mice compared to DW + APAP-treated mice, which had 100% mortality. Inhibition of ANX1 and ANX2 biosynthesis using cycloheximide (40 mg/kg BW in 5 mL DW/kg BW, IP) abolished this heteroprotection. Our data indicate that hepatic overexpression of ANX1 and ANX2 inhibits APAP-induced expansion of liver injury.
