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:

Cefotetan-induced immune hemolytic anemia. Immune hemolytic anemia due to a drug-adsorption mechanism has been described primarily in patients receiving penicillins and first-generation cephalosporins. We describe a patient who developed anemia while receiving intravenous cefotetan. Cefotetan-dependent antibodies were detected in the patient's serum and in an eluate prepared from his red blood cells. The eluate also reacted weakly with red blood cells in the absence of cefotetan, suggesting the concomitant formation of warm-reactive autoantibodies. These observations, in conjunction with clinical and laboratory evidence of extravascular hemolysis, are consistent with drug-induced hemolytic anemia, possibly involving both drug-adsorption and autoantibody formation mechanisms. This case emphasizes the need for increased awareness of hemolytic reactions to all cephalosporins.
