Inflammatory Surrogate Parameters for Predicting Ifosfamide-Induced Neurotoxicity in Sarcoma Patients. J Clin Med 2022; 11:jcm11195798. [PMID: 36233666 PMCID: PMC9572151 DOI: 10.3390/jcm11195798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/24/2022] [Accepted: 09/27/2022] [Indexed: 11/25/2022] Open
Abstract
Sarcomas compromise a heterogenous group of tumors of a mesenchymal origin. Although treatment options in many solid tumors have evolved over the past decades, the treatment of advanced sarcoma is still based on conventional chemotherapeutic agents. Beside anthracyclines, alkylating agents such as ifosfamide are frequently used in sarcoma treatment. However, treatment with ifosfamide can cause severe dose- and treatment-limiting side effects, such as ifosfamide-induced neurotoxicity (IIN). Especially in sarcoma, consecutive risk assessment analyses investigating the individual factors associated with the increased incidence in IIN, remain insufficient so far. In this retrospective analysis, we investigated 172 sarcoma patients treated with ifosfamide. Out of 172 patients, 49 patients (28.5%) developed IIN. While gender, age, histologic origin, and tumor stage were not associated with the occurrence of IIN, infusion times, simultaneous radiotherapy, and concomitant use of opioids or anticonvulsants affected the risk of developing IIN. Sarcoma patients with IIN showed an alteration in several inflammatory markers, including a lower lymphocyte count, hemoglobin levels, and calcium levels, as well as elevated GGT, sodium, and CRP levels. Remarkably, the occurrence of IIN was associated with a worse prognosis regarding progression free and overall survival. In addition, high CTCAE grades were negatively associated with overall survival in sarcoma. The observation that an inflammatory state is associated with an increased risk of IIN in sarcoma patients can be used prospectively to further investigate the relationship of inflammation and IIN. In addition, the easily accessible blood markers used in our study to predict IIN can be incorporated into clinical decision making.

A novel case of prolonged Ifosfamide encephalopathy and long-term treatment with methylene blue: a case report and review of literature. BMC Pediatr 2022; 22:76. [PMID: 35109795 PMCID: PMC8807677 DOI: 10.1186/s12887-022-03144-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 01/27/2022] [Indexed: 11/22/2022] Open
Abstract
Background Encephalopathy following Ifosfamide treatment is a well-described phenomenon that is typically treated with Methylene Blue (MB). Chloroacetaldehyde, a potentially neurotoxic metabolite of Ifosfamide is hypothesized to cause this encephalopathy. Current guidelines for treatment is to stop Ifosfamide and provide supportive care. MB acts to inhibit Chloroacetaldehyde formation and has been described as a therapy and prophylaxis for Ifosfamide-encephalopathy. MB is effective within 30 min and lasts up to 3 days. Prolonged encephalopathy and MB therapy has not been described in the literature as lasting longer than 30 days following treatment. Case presentation We present the case of an 11-year-old female with autistic spectrum disorder and recurrent episodes of severe somnolence for 7 months following Ifosfamide therapy for her Non-Germinomatous Germ Cell Tumor (GCT). Periods of somnolence occurred prior to receiving cranial RT. Administration of MB gave immediate but limited response, with resolution of somnolence lasting 1-2 days between administrations. The somnolence could not be explained by neuroimaging or laboratory evaluation, but EEG indicated persistent encephalopathy. Conclusion A literature review determines that neurotoxicity is a side effect of Ifosfamide, but this effect has not been described persisting longer than 30 days. Our case continued to require treatment with MB for 7 months following cessation of therapy. We report these novel clinical findings, and hypothesize that there could be a genetic/metabolic component linking this reaction to Ifosfamide with the case patient’s pre-existing autism. This possible association may also correlate to the already-established link between autism and the development of GCTs. This hypothesis leads to further discussion on the suitable usage of Ifosfamide in children with co-morbidities and the necessity of screening prior to its usage.

Abstract
BACKGROUND Ifosfamide-induced encephalopathy (IIE) is a rare and serious adverse reaction. Thus far, no standard medication has been documentedto be efficient in the reversal of IIE, and while ifosfamide infusion interruption and hydration are recommended, methylene blue (MB) administration remains controversial. METHODS We retrospectively reviewed medical records to assess cases with IIE after ifosfamide infusion. We included all patients having received an ifosfamide infusion during their hospitalization in the medical oncology unit of the National Institute of Oncology in Rabat, Morocco, between September 2016 and September 2017. We subsequently conducted a literature review to determine the role of MB in IIE by searching PubMed using the terms "Methylene Blue" and "Ifosfamide". RESULTS A total of 88 patients received ifosfamide, and four patients had IIE. Ifosfamide infusion was stopped immediately after the IIE occurrence, and patients underwent renal function correction with hydration. All patients received MB infusion, and three patients had an improvement of their neurological status. As regards the literature review, 34 articles were reviewed and 16 items were included in the review. Overall, 38 (65.5%) patients received MB infusion and 28 (75.6%) patients responded favorably to the treatment. CONCLUSIONS Methylene blue can be used as a treatment for IIE owing to the severity of the IIE as well as absence of standard medication. Nonetheless, side effects such as serotonergic syndrome should be investigated. More broadly, prospective studies and controlled trials are needed to explore the contribution of MB in IIE management and encourage its use.

Neurotoxicity of antineoplastic drugs: Mechanisms, susceptibility, and neuroprotective strategies. Adv Med Sci 2020; 65:265-285.

Abstract
This review summarizes the adverse effects on the central and/or peripheral nervous systems that may occur in response to antineoplastic drugs. In particular, we describe the neurotoxic side effects of the most commonly used drugs, such as platinum compounds, doxorubicin, ifosfamide, 5-fluorouracil, vinca alkaloids, taxanes, methotrexate, bortezomib and thalidomide. Neurotoxicity may result from direct action of compounds on the nervous system or from metabolic alterations produced indirectly by these drugs, and either the central nervous system or the peripheral nervous system, or both, may be affected. The incidence and severity of neurotoxicity are principally related to the dose, to the duration of treatment, and to the dose intensity, though other factors, such as age, concurrent pathologies, and genetic predisposition may enhance the occurrence of side effects. To avoid or reduce the onset and severity of these neurotoxic effects, the use of neuroprotective compounds and/or strategies may be helpful, thereby enhancing the therapeutic effectiveness of antineoplastic drug.

Abstract
Ifosfamide is an alkylating chemotherapeutic agent used in the treatment of many malignancies. Ifosfamide-induced encephalopathy is one potential side effect that represents a major drawback to ifosfamide therapy and often necessitates discontinuation of chemotherapy. Previous reports demonstrate moderate effectiveness of prophylactic methylene blue at thwarting ifosfamide-induced encephalopathy. This is a report of a 64-year-old female with relapsed double-hit diffuse large B-cell lymphoma who developed severe altered mental status and neurological symptoms after receiving a second dose of ifosfamide as part of her salvage standard dose R-IE (rituximab, ifosfamide, etoposide), in preparation for chimeric antigen receptor T-cell therapy. Ifosfamide was stopped and extensive metabolic and infectious workups, in addition to brain images, were all unremarkable. Her symptoms were attributed to ifosfamide. Prior to initiating cycle 2 of R-IE, she was started on prophylactic oral thiamine 100 mg, once a day, one week prior to her admission, methylene blue 50 mg intravenous every 6 h (for a total of four doses) and intravenous hydration with normal saline starting on day one of admission. Ifosfamide was administered in the standard dose 2000 mg/m2, days 1-3 as continuous intravenous infusion over 24 h. She tolerated the first two days of ifosfamide well and only developed mild encephalopathy during her last dose of ifosfamide. Her symptoms resolved completely without any intervention the following day and she completed all scheduled doses. She eventually received chimeric antigen receptor T-cell therapy. Our report demonstrates the use of hydration, methylene blue, and thiamine as a successful secondary prevention regimen for ifosfamide-induced encephalopathy.

Abstract
Ifosfamide is a cytotoxic drug usually used in malignant sarcomas. The nephrotoxicity of this agent has been described essentially among children, revealed by renal failure and proximal tubulopathy. We recently conducted a retrospective multicentre study, describing 34 adult patients admitted for ifosfamide nephrotoxicity. More than 80% of them presented with renal failure, diagnosed up to 48 months after ifosfamide administration. A Fanconi syndrome with hypophosphoremia, hypokaliemia, glucosuria and low-molecular weight proteinuria, was present in two third of all cases. Median estimated glomerular filtration rate was 31mL/min 1 month and 38mL/min 3 months after ifosfamide infusion, versus 67mL/min at baseline. Renal biopsy, performed in 14 of these patients, showed acute tubular necrosis with vacuolization of proximal tubular epithelial cells with marked nuclear modifications, whereas electron microscopy revealed major changes of mitochondrial structure inside those cells, suggesting a tenofovir-like mechanism of nephrotoxicity. After a median follow-up of 31 months, ten patients out of 34 reached stage 5 chronic kidney disease, requiring dialysis in five cases. Poor renal prognosis was associated with concomitant cisplatin use (P=0.02) and with older age at presentation (P=0.04). In conclusion, ifosfamide nephrotoxicity is often severe and irreversible, leading to proximal tubulopathy and sometimes-severe chronic kidney failure, that can be immediate or delayed, sometimes diagnosed months after chemotherapy completion.

Abstract
Neurotoxicity is a clinically relevant adverse event observed with the use of ifosfamide. It is usually mild, occasionally severe and seldom fatal. Ifosfamide-induced encephalopathy requires interruption of chemotherapy, intravenous hydration and administration of methylene blue. Less is known about the efficacy of methylene blue in avoiding a second episode of ifosfamide-induced encephalopathy while maintaining chemotherapy with ifosfamide. We report a case of a different clinical manifestation of ifosfamide-induced encephalopathy after continued ifosfamide use and despite methylene blue in a patient with retroperitoneal sarcoma.

Abstract
PURPOSE Ifosfamide-induced encephalopathy is a neurotoxic adverse effect of ifosfamide chemotherapy. The objective of this study was to determine the incidence of encephalopathy in patients with lymphoma and sarcoma receiving ifosfamide chemotherapy and assess for potential risk factors that influence the incidence of encephalopathy. METHODS A retrospective study of sarcoma and lymphoma patients receiving ifosfamide chemotherapy was performed at the participating institutions. Enrollment began 1 July 2011 and continued chronologically backwards until 100 sarcoma and 100 lymphoma patients were enrolled. Identification of ifosfamide-induced encephalopathy events was performed by reviewing provider documentation of ifosfamide infusions. Logistic regression was employed to determine associations between risk factors and ifosfamide-induced encephalopathy events. RESULTS Of the 200 patients enrolled, 29 (14.5%) patients experienced encephalopathy. Ifosfamide-induced encephalopathy occurred more frequently in the sarcoma population than the lymphoma population (24 vs. 5 patients, p < 0.001). In addition to cancer type, prior use of cisplatin, concomitant opioids, and use of CYP2B6 inhibitors remained as significant variables in the multivariate model conferring a 12.47, 2.81, and 5.17 increased odds of experiencing encephalopathy, respectively. The odds of experiencing encephalopathy were 9.0 and 1.37 times higher for a one-unit increase in serum creatinine and hemoglobin, respectively, and 0.15 times lower for a one-unit increase in albumin. CONCLUSIONS This is the first study to demonstrate that patients with sarcoma experienced ifosfamide-induced encephalopathy more often than those with lymphoma. For all patients, predisposing factors for ifosfamide-induced encephalopathy included previous cisplatin exposure, concomitant opioids and CYP2B6 inhibitors. Laboratory values that increased ifosfamide-induced encephalopathy risk included low serum albumin, increased serum creatinine, and increased hemoglobin.

Abstract
Mitochondrial dysfunction (primary or secondary) is detrimental to intermediary metabolism. Therapeutic strategies to treat/prevent mitochondrial dysfunction could be valuable for managing metabolic and age-related disorders. Here, we review strategies proposed to treat mitochondrial impairment. We then concentrate on redox-active agents, with mild-redox potential, who shuttle electrons among specific cytosolic or mitochondrial redox-centers. We propose that specific redox agents with mild redox potential (-0.1 V; 0.1 V) improve mitochondrial function because they can readily donate or accept electrons in biological systems, thus they enhance metabolic activity and prevent reactive oxygen species (ROS) production. These agents are likely to lack toxic effects because they lack the risk of inhibiting electron transfer in redox centers. This is different from redox agents with strong negative (-0.4 V; -0.2 V) or positive (0.2 V; 0.4 V) redox potentials who alter the redox status of redox-centers (i.e., become permanently reduced or oxidized). This view has been demonstrated by testing the effect of several redox active agents on cellular senescence. Methylene blue (MB, redox potential ≅10 mV) appears to readily cycle between the oxidized and reduced forms using specific mitochondrial and cytosolic redox centers. MB is most effective in delaying cell senescence and enhancing mitochondrial function in vivo and in vitro. Mild-redox agents can alter the biochemical activity of specific mitochondrial components, which then in response alters the expression of nuclear and mitochondrial genes. We present the concept of mitochondrial electron-carrier bypass as a potential result of mild-redox agents, a method to prevent ROS production, improve mitochondrial function, and delay cellular aging. Thus, mild-redox agents may prevent/delay mitochondria-driven disorders.

Abstract
SUMMARY A serious adverse effect that can limit the utility of ifosfamide is neurotoxicity, known as ifosfamide-induced encephalopathy (IIE). Information regarding the usefulness of prophylactic administration of methylene blue, thiamine, and albumin to reduce the incidence of IIE is scarce. We present the results of a retrospective chart review evaluating the incidence of IIE in adult patients who received ifosfamide to treat sarcoma at the University of Washington within a 2-year period. Patients who received methylene blue, thiamine, and/or albumin were compared to patients who did not receive these prophylactic agents concurrently with ifosfamide. The primary objective was to evaluate if prophylaxis is associated with a reduced incidence of IIE. Identifying risk factors associated with IIE was a secondary objective. The cost of using prophylaxis with ifosfamide administration was reviewed. RESULTS A total of 166 cycles were included. For the primary endpoint, more cycles in the prophylaxis group had patients with symptoms of IIE (21.1% in the prophylaxis group vs. 8.4% in the nonprophylaxis group); p =0.026. The average number of risk factors per cycle was the same in each group; however, the type of risk factors differed. CONCLUSIONS Prophylaxis was not associated with a reduced incidence of IIE, and it does not appear to delay time to onset of symptoms at our institution. RESULT of this study provide no support for using methylene blue, thiamine, and/or albumin as routine prophylaxis when administering ifosfamide to adults with sarcoma.

Abstract
Ifosfamide is a widely used chemotherapeutic agent for the treatment of a broad spectrum of solid tumors. CNS toxicity is a well-described side effect of ifosfamide, but the mechanism of ifosfamide-induced neurotoxicity remains poorly defined. We present two pediatric cases of hemiballismic limb movements in the setting of ifosfamide-associated encephalopathy. To our knowledge, there have been no prior reports of ifosfamide-induced hemiballism in pediatric patients. One of our patient's encephalopathy and abnormal movements may have improved after the administration of methylene blue and thiamine.

Abstract
Central and peripheral nervous system toxicity are frequent complications of most chemotherapy regimens, often leading to reduction of dosages or cessation of the responsible drugs. However, sometimes the afflicted toxicity may not be reversible, especially if it is not recognized early, further compromising the quality of life of the cancer patients. The most common chemotherapeutic agents that might cause CNS toxicity manifested as encephalopathy of various severities include methotrexate, vincristine, ifosfamide, cyclosporine, fludarabine, cytarabine, 5-fluorouracil, cisplatin and the interferons (alpha > beta). Involvement of the peripheral nervous system manifested as distal peripheral neuropathy results after therapy with cisplatin, vincristine, taxanes, suramin and thalidomide. Although several compounds have been proposed as neuroprotective agents, few have been shown to be active against the chemotherapy induced neurotoxicity.

Abstract
Neurologic dysfunction is a well-recognized adverse effect of cancer therapeutics. The most common manifestations include peripheral neuropathy and encephalopathy. Often, symptoms resolve or improve upon removal of the offending agent; therefore, it is essential that clinicians recognize the symptoms and signs of injury. Occasionally, symptoms persist or develop after discontinuation of medication and may culminate in disability and diminished quality of life. As our understanding of neurotoxicity improves, medications with less potential for injury may be developed. In addition, potential antidotes to prevent or reverse injury may emerge. This review focuses on the clinical features, mechanisms, and possible therapeutics of the neurotoxicity of chemotherapy. In particular, oxaliplatin, thalidomide, methotrexate, ifosfamide, cytarabine, amifostine, acetyl-L-carnitine, methylene blue, cytokines, and neurotrophins are discussed.
