You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Disease", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Naloxone", ...], "Disease" : ["Hypotensive", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Lethal anuria complicating high dose ifosfamide chemotherapy in a breast cancer patient with an impaired renal function. A sixty-year-old woman with advanced breast cancer, previously treated with cisplatin, developed an irreversible lethal renal failure with anuria, the day after 5 g/m2 bolus ifosfamide. Postrenal failure was excluded by echography. A prerenal component could have contributed to renal failure because of a transient hypotension, due to an increasing ascitis, occurring just before anuria. However, correction of the hemodynamic parameters did not improve renal function. Ifosfamide is a known nephrotoxic drug with demonstrated tubulopathies. We strongly suspect that this lethal anuria was mainly due to ifosfamide, occurring in a patient having received previous cisplatin chemotherapy and with poor kidney perfusion due to transient hypotension. We recommend careful use of ifosfamide in patients pretreated with nephrotoxic chemotherapy and inadequate renal perfusion.
