Therapeutic Potential of Capsaicin against Cyclophosphamide-Induced Liver Damage. J Clin Med 2023; 12:jcm12030911. [PMID: 36769559 PMCID: PMC9917381 DOI: 10.3390/jcm12030911] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 01/06/2023] [Accepted: 01/19/2023] [Indexed: 01/25/2023] Open
Abstract
Cyclophosphamide (CPM) is a classical alkylating agent used in different cancer chemotherapy regimens and is restricted due to severe adverse effects, including hepatotoxicity. Natural or plant-derived antioxidants such as capsaicin were utilized in this study to examine the hepatoprotective benefits against cyclophosphamide-induced hepatotoxicity. The rats were divided into five groups: a normal control group, a toxic group (CPM), an intraperitoneal injection of a single dose of 200 mg/kg b.w. on the fourth day, a pretreated group with two doses of CPS (10 mg and 20 mg/kg b.w.) orally for six consecutive days, and an intraperitoneal administration of 200 mg/kg b.w. on the fourth day of treatment. The fifth group was administered with the highest dose of CPS (20 mg/kg b.w.) orally for six consecutive days. After 24 h of administration of CPS, the rats were anesthetized, blood was collected, and the serum enzyme toxicity was evaluated. After the blood sampling and euthanasia of all the animals, the liver was isolated for further toxicity and histopathological examination. The results revealed that serum liver markers (AST, ALT, ALP, BLI) significantly increased after CPM administration, but were subsequently restored after CPS treatment with both doses. In addition, lipid peroxidation (MDA), inflammatory cytokines (IL-1β, TNF-α), and apoptotic markers (Caspase-3) increased, and antioxidant enzymes (GSH, CAT, SOD) were significantly decreased after CPM administration, and it was re-established by CPS treatment. However, CPS effectively protected against the CPM-induced histopathological architects of liver tissues. In conclusion, CPS attenuates CPM-induced hepatotoxicity via modulating oxidative stress, apoptotic signals, and cytokine pathway. Therefore, CPS could play a significant role as a supplement during the chemotherapy of patients.

Toxicol Res (Camb) 2020; 9:561-568. [PMID: 32905193 DOI: 10.1093/toxres/tfaa059] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 06/22/2020] [Accepted: 07/15/2020] [Indexed: 12/16/2022] Open
Abstract
Cyclophosphamide (CP) is one of the most potent alkylating agents and is widely used in the treatment of numerous neoplastic conditions, autoimmune diseases and following organ transplantation. Due to its ability to induce oxidative stress and subsequent apoptosis, CP is affiliated with many adverse effects with special emphasis on the highly prevalent hepatotoxicity. Dipeptidyl peptidase 4 (DDP-IV) inhibitors are being rediscovered for new biological effects due to their ability to target multiple pathways, among which is the phosphoinositide 3-kinase (PI3K) and protein kinase B (Akt) axis. This could offer protection to multiple organs against reactive oxygen species (ROS) through modulating sirtuin 1 (SIRT1) expression and, in turn, inactivation of forkhead box transcription factor of the O class 1 (FoxO1), thus inhibiting apoptosis. Accordingly, the current study aimed to investigate the potential therapeutic benefit of alogliptin (Alo), a DPP-IV inhibitor, against CP-induced hepatotoxicity through enhancing PI3K/Akt/SIRT1 pathway. Forty male Wistar rats were randomly divided into four groups. The CP-treated group received a single dose of CP (200 mg/kg; i.p.). The Alo-treated group received Alo (20 mg/kg; p.o.) for 7 days with single CP injection on Day 2. Alo successfully reduced hepatic injury as witnessed through decreased liver function enzymes, increased phospho (p)-PI3K, p-Akt, superoxide dismutase (SOD) levels, SIRT1 expression, p-FoxO1 and anti-apoptotic B-cell lymphoma 2 (Bcl-2). This resulted in decreased apoptosis, as witnessed through decreased caspase-3 levels and improved histopathological picture. In conclusion, the current study succeeded to elaborate, for the first time, the promising impact of Alo in ameliorating chemotherapy-induced liver injury.

Complement Ther Med 2019; 46:95-102.

Abstract
BACKGROUND AND AIMS Cyclophosphamide (CPh) is a frequently used drug, in human and animals for its immunosuppressive and anticancer potential. However, it is metabolized by the liver yielding damaging toxicants (to the liver itself and other non-target vital organs) via oxidative stress, apoptosis induction and finally necrosis. Since there is no escaping of using such harmful medications, we focused on alleviating its side-effects. Panax ginseng Meyer is a potent candidate, and we still lack adequate information on its hepatoprotective role against cyclophosphamide-induced liver-damage. METHODS Here, we used P. ginseng (Korean Red Ginseng) compared to vitamin-E (natural antioxidant) in combating CPh-induced liver damage. Forty-eight albino rats were divided into 6 groups, Control, Ginseng, Vitamin E, Cyclophosphamide (CPh), CPh + Ginseng or CPh + Vitamin-E. Blood samples were taken for biochemical analyses and liver samples were collected for histopathology, oxidative stress evaluation, and gene expression analyses. RESULTS In CPh group, typical CPh-liver damage was evident (higher levels of AST, ALT, ALP; lower albumin and total proteins levels; lower liver tissue concentrations of SOD, GPX and CAT and higher MDA; injured liver histopathological picture; and finally increased TNF-α, IL-1β and Caspase3 and decreased BCL-2 genes expression). All these were abolished with either P. ginseng or vitamin-E administration. However, P. ginseng was overall superior to vitamin-E, especially in restoring blood biochemical findings and damaged histopathological picture. CONCLUSIONS Therefore, P. ginseng is a potent hepatoprotector (vitamin-E to a lesser extent) and should be considered where liver damage is expected secondary to damaging medications; as cyclophosphamide.

Abstract
OBJECTIVE: To report the safety and efficacy of long-term, low-dose cyclophosphamide therapy in a child with idiopathic pulmonary hemosiderosis (IPH). CASE SUMMARY: A 7-year-old boy diagnosed with IPH 4 years previously was initially prescribed prednisolone. Because he only had a transient response to prednisolone, oral cyclophosphamide 2 mg/kg/d was later added. A dramatic improvement was noted during the subsequent follow-up. One year after cyclophosphamide therapy, the patient suddenly developed thrombocytopenia (platelet count 75 times 103/mm3), with the platelet count decreasing to 10 times 103/mm3 over the following 10 months. Cyclophosphamide was tapered to an alternating daily dosage of 1 mg/kg. The tapering resulted in a subsequent increase in the platelet count, which was maintained between 20 and 50 times 103/mm3 without occurrence of petechiae or spontaneous bleeding. Under this reduced dosing regimen, the disease has remained in remission for >1 year. DISCUSSION: Due to the low prevalence of IPH, only limited data document the safety and efficacy of immunosuppressive therapy in treating this disease. Although our patient showed a good response to low-dose cyclophosphamide, he developed thrombocytopenia with its use. The mechanism is unclear, but it may be similar to that of high-dose cyclophosphamide-induced myelosuppression. Due to the development of thrombocytopenia, the use of cyclophosphamide was maintained under a reduced dosing regimen. The benefit of long-term immunosuppressive therapy is controversial, and more clinical evidence is required to support its continued usage. CONCLUSIONS: Long-term, low-dose cyclophosphamide is effective in treating childhood IPH, but caution should be exercised due to the possible development of thrombocytopenia. Periodic monitoring of the platelet count in long-term treatment is recommended.

Ginseng alleviates cyclophosphamide-induced hepatotoxicity via reversing disordered homeostasis of glutathione and bile acid. Sci Rep 2015; 5:17536.

Abstract
Cyclophosphamide (CP), a chemotherapeutic agent, is restricted due to its side effects, especially hepatotoxicity. Ginseng has often been clinically used with CP in China, but whether and how ginseng reduces the hepatotoxicity is unknown. In this study, the hepatoprotective effects and mechanisms under the combined usage were investigated. It was found that ginseng could ameliorate CP-induced elevations of ALP, ALT, ALS, MDA and hepatic deterioration, enhance antioxidant enzymes’ activities and GSH’s level. Metabolomics study revealed that 33 endogenous metabolites were changed by CP, 19 of which were reversed when ginseng was co-administrated via two main pathways, i.e., GSH metabolism and primary bile acids synthesis. Furthermore, ginseng could induce expression of GCLC, GCLM, GS and GST, which associate with the disposition of GSH, and expression of FXR, CYP7A1, NTCP and MRP 3, which play important roles in the synthesis and transport of bile acids. In addition, NRF 2, one of regulatory elements on the expression of GCLC, GCLM, GS, GST, NTCP and MRP3, was up-regulated when ginseng was co-administrated. In conclusion, ginseng could alleviate CP-induced hepatotoxicity via modulating the disordered homeostasis of GSH and bile acid, which might be mediated by inducing the expression of NRF 2 in liver.

Abstract
PATIENT Male, 52 FINAL DIAGNOSIS: L-asparaginase associated steatohepatitis and pulmonary Pneumocystis Symptoms: Cholestasis • hepatomegaly MEDICATION Corticosteroids • atovaquone • antioxidant therapy Clinical Procedure: Liver biopsy Specialty: Hematology • Infectious Disease • Hepatology. OBJECTIVE Challenging differential diagnosis. BACKGROUND L-asparaginase (L-aspa) is an important component of chemotherapy in acute lymphoblastic leukemia (ALL). Main adverse effects of L-aspa include allergic reactions, pancreatitis, thrombosis, and liver disturbances. L-aspa-associated steatohepatitis may be a life-threatening disorder but has very rarely been reported in the literature. CASE REPORT ALL was diagnosed in a 52-year-old man with a history of cardiovascular disease and obesity. Chemotherapy combining daunorubicin, vincristine, cyclophosphamide, and L-aspa was initiated. At the time of neutrophil recovery, the patient developed hepatomegaly in the context of fever and cough. On day 25, after 6 injections of L-aspa, liver function tests showed elevated alkaline phosphatase and transaminases levels. Although pulmonary Pneumocystis was concomitantly diagnosed, biological hepatic disturbances were attributed to L-aspa-associated toxicity. A liver biopsy revealed severe diffuse micro- and macrovesicular steatosis affecting more than 50% of hepatocytes. Other causes of liver dysfunction were eliminated. L-aspa and other hepatotoxic treatments were stopped, and treatment with antioxidant therapy, atovaquone, and corticosteroids was initiated. The clinical outcome was rapidly favorable. CONCLUSIONS This case illustrates the necessity of carefully monitoring liver function test results in patients receiving L-aspa. In case of major increase of hepatic enzymes, a hepatic biopsy should rapidly be performed to exclude differential diagnosis in patients with prolonged neutropenia. L-aspa should be stopped and further administration definitively avoided. In the present case, the early administration of systemic corticosteroids as treatment of the concomitant Pneumocystis with hypoxemia could have participated to the favorable clinical evolution.

Abstract
Three months after diagnosis of Wegener granulomatosis, an 84-year-old woman who was treated with cyclophosphamide (CPY) and prednisone developed deranged liver function tests (LFTs). Treatment with CPY was held, which led to normalization of LFTs, but after reinitiating of CPY, LFTs started increasing. Liver biopsy showed noncaseating epithelioid granulomas within liver lobules consistent with granulomatous hepatitis. Patient died within 2 months secondary to liver failure. This elevation of transaminases was considered to be secondary to CPY-induced hepatotoxicity. Involvement of liver in patients with Wegener granulomatosis is seen but it presents with necrotizing granulomatous vasculitis. CPY-induced hepatitis is an extremely rare phenomenon with only 1 case reported in literature. Clinicians and hepatologists should be aware of this potentially serious complication when CPY therapy is initiated. Baseline LFTs and periodic assessment are recommended before and during treatment with CPY.

Abstract
The pharmacokinetics of cyclophosphamide (CY) and its metabolites hydroxycyclophosphamide and carboxyethylphosphoramide mustard were determined in 75 patients receiving targeted oral busulfan followed by i.v. CY ((T)BU/CY) and in 147 patients receiving i.v. CY followed by total body irradiation (CY/TBI) in preparation for hematopoietic cell transplantation (HCT). In the (T)BU/CY patients only, the association of the pharmacokinetic data with liver toxicity, relapse, and survival was evaluated. CY was infused at 60 mg/kg/day over 1 or 2 hours on 2 consecutive days; the majority of patients had BU levels targeted to a steady state plasma concentration (Css) of 800-900 ng/mL. Systemic exposure (i.e., area under the concentration-time curve [AUC]) of CY, hydroxycyclophosphamide, and carboxyethylphosphoramide mustard was measured. Liver toxicity was assessed as the development of hepatic sinusoidal obstruction syndrome (SOS). CY metabolism was highly variable and age dependent. (T)BU/CY-treated patients had lower AUC(CY) (P < .0001), higher AUC(HCY) (P < .0001), and higher AUC(CEPM) (P = .15) than CY/TBI-conditioned patients. Among patients receiving (T)BU/CY, 17 (23%) developed SOS, and there were no statistically significant associations between the AUC of CY or its metabolites and SOS, nonrelapse mortality, relapse, or survival (all P >.15). In conclusion, CY exhibits conditioning-regimen dependent pharmacokinetics and pharmacodynamics, suggesting that lowering CY doses is unlikely to improve outcomes to (T)BU/CY. Alternative strategies, such as administering i.v. busulfan or CY before BU, should be explored.

Abstract
Although chemotherapy generally is accompanied by regular testing for liver enzyme abnormalities, atypical reactions may occur that escape ordinary detection, because hepatocyte injury is not the primary event. The presence of fatty liver, mitochondrial changes, and even biliary abnormalities can be associated with normal or nearly normal liver enzyme levels. This article discusses unique aspects of liver damage associated with cancer chemotherapy. These unique reactions merit special attention and a special vigilance from clinicians.

Abstract
Dose adaptation for liver disease is important in patients treated with antineoplastic drugs because of the high prevalence of impaired liver function in this population and the dose-dependent, frequently serious adverse effects of these drugs. We classified the antineoplastic drugs marketed in Switzerland at the end of 2004 according to their bioavailability and/or hepatic extraction to predict their kinetic behaviour in patients with decreased liver function. This prediction was compared with kinetic studies carried out with these drugs in patients with liver disease. The studies were identified by a structured, computer-based literature search. Of the 69 drugs identified, 52 had a predominant extrarenal (in most cases hepatic) metabolism and/or excretion. For 49 drugs, hepatic extraction could be calculated and/or bioavailability data were available, allowing classification according to hepatic extraction. For 18 drugs, kinetic studies have been reported in patients with impaired liver function, with the findings generally resulting in quantitative recommendations for adaptation of the dosage. In particular, recommendations are precise for 16 drugs excreted by the bile (e.g. doxorubicin and derivatives and vinca alkaloids). Validation studies comparing such recommendations with kinetics and/or dynamics of antineoplastic drugs in patients with decreased liver function have not been published. We conclude that there are currently not enough data for safe use of cyctostatics in patients with liver disease. Pharmaceutical companies should be urged to provide kinetic data (especially hepatic extraction data) for the classification of such drugs and to conduct kinetic studies for drugs with primarily hepatic metabolism in patients with impaired liver function to allow quantitative advice to be given for dose adaptation.
