Повний текст джерелаSpecific Aims: To determine the cost of treatment of oral and intravenous n-acetylcysteine (IV NAC) in acute acetaminophen (APAP) toxicity using the length of treatment and length of hospital stay. Methods: A retrospective chart review of Arizona Poison and Drug Information Center electronic records from 2009-2012 and January-June 2013 were evaluated. The following information was collected: age, sex, use oral or intravenous NAC, length of treatment, length of hospital stay (intensive care unit (ICU) and non-ICU) and use of antiemetic. The mean length of stay (MLOS) was calculated for each group as well as the cost of IV and oral NAC. These means were then compared using t-test for independent groups to test for significance. The average total cost of IV and oral NAC treatment was calculated by using monetary values from primary literature. A sensitivity analysis was performed to test the possible effects of an increase or decrease of the final costs by 5 to 10%. Main Results: Patients (≥18 yrs) being treated with IV or oral NAC for acute APAP toxicity (≤8 hours prior to ingestion) were included in this study. A total of 47 patients met the inclusion criteria. Length of hospital stay was shorter in patients receiving IV NAC (42.5% 24-24hr; 37.5% 48-72hr) compared to patients receiving oral NAC (28.6% 48-72hr, 71.4% >72hrs; p<0.001). Total cost of ICU/non-ICU stay in patients receiving IV NAC ($8,720/$3010) was less than patients receiving oral NAC ($12,321/$4703); however, cost of IV NAC-extended (37hrs) in ICU/non-ICU ($13,153/$5535) was greater than oral NAC. The sensitivity analysis performed demonstrated that an increase or a decrease by 5 to 10% in change of cost does not affect our final conclusion. Conclusion: The cost of treatment of IV NAC is lower due to shorter LOS of patients treated with IV NAC (p<0.001). However, when an extended course of treatment is medically necessary for patients on IV NAC then the cost of treatment with IV NAC exceeds the cost of treatment with oral NAC.

Повний текст джерелаObesity and nonalcoholic fatty liver disease (NAFLD) are able to increase the risk and the severity of hepatotoxicity induced by some xenobiotics including drugs, but the involved mechanisms are still poorly understood. For toxic compounds such as ethanol and acetaminophen (APAP), a role of hepatic cytochrome P450 2E1 (CYP2E1) is suspected since the activity of this enzyme is consistently enhanced during obesity and NAFLD. The first aim of our experimental study was to set up a cellular model of NAFLD characterized not only by triglyceride accumulation but also by higher CYP2E1 activity. To this end, differentiated human HepaRG cells were incubated during one week with stearic acid, or oleic acid, in the presence of 3 different concentrations of insulin. Cellular triglycerides and the expression of lipid-responsive genes were similar with both fatty acids. However, CYP2E1 activity was significantly increased only by stearate and this was associated with lower CYP3A4 activity, another metabolic feature reported in NAFLD. CYP2E1 activity in HepaRG cells was reduced by insulin in a concentration-dependent manner and this effect was reproduced in cultured primary human hepatocytes. Hence, the highest CYP2E1 activity was observed in HepaRG cells with stearate and without insulin. Next, the second aim of our study was to assess APAP cytotoxicity in HepaRG cells presenting or not lipid accretion and CYP2E1 induction. Experiments with a large range of APAP concentrations (1 to 20 mM) showed that the cellular loss of ATP and glutathione (GSH) was almost always stronger in the presence of stearic acid. In cells pretreated with the CYP2E1 inhibitor chlormethiazole (CMZ), recovery of cellular ATP was significantly higher in the presence of stearic acid with both low (2.5 mM) and high (20 mM) concentrations of APAP. However, in the absence of insulin, CMZ-induced ATP recovery was significantly greater only for 20 mM of APAP. Surprisingly, there was no recovery of cellular GSH and no reduction of APAP-protein adducts following CMZ pretreatment. Finally, levels of APAP-glucuronide were significantly enhanced in the presence of insulin. Hence, when studied in specific conditions of culture, the HepaRG cell line can be a valuable model of human NAFLD, especially regarding CYP2E1 and CYP3A4 activity. Our data also suggest that higher CYP2E1 activity in NAFLD could be secondary to the hepatic accumulation of some fatty acids and to the presence of low insulin signaling. This cellular model can be thus used to unveil the main metabolic and hormonal factors favoring APAP hepatotoxicity in obese individuals. This thesis also includes a review on APAP hepatotoxicity in the context of obesity and NAFLD (Michaut et al., Liver Int 2014)

Obesity is associated with increased tissue and systemic inflammation and oxidative stress. Obesity induced by high-fat diets enhances oxidative stress and glutathione disulfide content, and reduces the level of glutathione and activities of glutathione peroxidase, glutathione reductase, and glutathione S-transferase. Several experimental and epidemiological studies have demonstrated that acetaminophen has been associated with elevated levels of oxidative stress, which also causes impaired liver functions. Acetaminophen is the most widely used pharmaceutical analgesic and antipyretic agent in the world. However, the literature regarding the effect of acetaminophen-induced changes of cytokines and oxidative stress in obese rats remains unclear. Therefore, the aim of this study is to evaluation of the effect of acetaminophen-induced changes of cytokines and oxidative stress in normal and high fat diet (HFD)-induced obese rats. The data indicated that body weight, perirenal adipose tissue, and epididymal adipose tissue in high fat diet-low dose-acetaminophen (HLA) and high fat diet-high dose-acetaminophen (HHA) groups were significantly decreased as compared to the HFD group. Serum parameter levels of total cholesterol, LDL-cholesterol, aspartate aminotransferase, alanine aminotransferase, interleukin-6, and interleukin-1β in HHA group was significantly increased as compared to the HFD group. The serum parameter levels of alanine aminotransferase and aspartate aminotransferase in HHA group was significantly increased as compared to the normal diet-high dose-acetaminophen (NHA) group. In the trolox equivalent antioxidant capacity (TEAC) and malondialdehyde (MDA), hepatic TEAC in HLA and HHA groups were significantly decreased as compared to the HFD group. Moreover, hepatic and serum levels of MDA in HHA group was significantly increased as compared to the HFD group. In the hepatic antioxidant enzymatic activities, the levels of glutathione, glutathione reductase, and catalase in HHA group was significantly decreased as compared to the HFD group. The pathological results show that the scores of portal inflammation and intralobular degeneration and inflammation in HLA and HHA groups were significantly increased as compared to normal diet-low dose-acetaminophen (NLA) and NHA groups. In the molecular mechanism, hepatic gene expressions of CYP2E1, MCP-1, IL-6, Stat1, Stat3, Jak2, and SOCS3 in HHA group were significantly increased as compared to the HFD group. Hepatic antioxidant related genes of HO-1, catalase, γ-GCS, GPx1, GPx4, SOD1, SOD2, and Nrf2 in HHA group was significantly decreased as compared to the NHA group. Hepatic pro-oxidant related genes of p47phox and Nox1 in HHA group was significantly increased as compared to the NHA group. These results demonstrated that the intake of acetaminophen can enhance oxidative stress and cause impaired liver functions in rats fed a high-fat diet.
