hyperlipidemia. Medications are aspirin, lisinopril, hydrochlorothiazide, a glyburide, and lovastatin. She has no allergies.
Her physical examination is unremarkable. Laboratory studies including serum creatinine, blood urea nitrogen, electrolytes, liver function tests, and a fasting lipid panel are normal. Her hemoglobin A1c is 6.3%.
Urinalysis shows 15 leukocytes per high-power field and bacteria; no erythrocytes, protein, or glucose are noted. Urine culture grows Escherichia coli of at least 105 colony- forming units (cfu)/mL.
Repeat urinalysis and urine culture confirm these results.
