A 78-year-old male patient is transferred from the nursing home to the hospital for treatment of pneumonia. The patient has a past medical history that is significant for hypertension, congestive heart failure, type 2 diabetes mellitus, and gastroesophageal reflux disease (GERD) for which the patient takes amlodipine besylate, hydrochlorothiazide, metformin, and omeprazole, respectively. The patient has been treated in the past for pneumonia with intravenous (IV) antibiotics. The current sputum culture is positive for Streptococcus pneumoniae, and the patient is started on IV ceftriaxone. In addition, acetaminophen is given to control the patient’s fever (temperature 101.2°F on admission). On the fifth hospital day, the patient is noted to have worsening anemia (drop of hemoglobin [Hgb] level from 10.5 to 7.2 g/dL) with elevation of total bilirubin (6.2 mg/L), lactate dehydrogenase (LDH, 2100 U/L), and reticulocytes (10.3%). In addition, the haptoglobin is noted to be less than 7 mg/dL. A type and screen sample (ethylenediaminetetraacetic acid [EDTA] anticoagulant) is submitted to the blood bank along with a request for two units of RBCs and a direct antiglobulin test (DAT) profile for workup of hemolytic anemia.
