Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: patient is a 60-year-old male status post orthotopic liver transplant on secondary to alcohol cirrhosis. past medical history significant for diabetes, esophageal varices, and portal hypertension. patient was discharged after that operation on . at that time, the patient's liver enzymes were within normal limits. ast 25, alt 53, alkaline phosphatase 243, total bilirubin 1.4. patient was readmitted on . patient was admitted from center for a hematocrit of 21. on hospital day three, the patient's total bilirubin was 3.7 and continued to rise up to 5.3 on hospital day #5. at that time, an ercp was done that revealed anastomotic stricture and a stent and a sphincterotomy was performed. the patient was also febrile to 100.4, and was started on zosyn on hospital day #6. on hospital day nine, the patient's lfts continued to rise with ast 177, alt 234, alkaline phosphatase 804, total bilirubin 7.6. duplex ultrasound was performed, which revealed normal blood flow. on hospital day #12, patient's bilirubin rose to 16.6, at which time an arteriogram was done which revealed good inflow and outflow. on hospital day 13, patient's bilirubin continued to rise to 18.3. liver biopsy was performed at that time, which revealed biliary damage. at that time, a ptc drain was placed. the patient continued to deteriorate developing a diffuse intrahepatic bile duct stricture and cholestasis complicated by cholangitis. the patient was on linezolid, vancomycin, zosyn, and meropenem for antibiotics. hepatic artery was patent and there was no etiology to date for destruction of his intrahepatic bile ducts with the exception of possibly a diffuse preservation injury. following several weeks were significant for recurrent bouts of cholangitis, jaundice, malnutrition, ascites, and renal insufficiency. patient was relisted at that time for liver transplantation, and an appropriate donor was identified. patient was taken to the or on for retransplantation. operative findings: liver was markedly enlarged and soft consistent with multiple intrahepatic fluid collections and bile lumens. no intraabdominal abscesses or fluid collection found. hepatic artery was widely patent and had excellent flow. the patient had moderate intraabdominal adhesions especially in the infrahepatic space. the patient received 21 units of fresh-frozen plasma, 11 units of packed red blood cells, 4 units of platelets, and 2 units of cryo, 4,000 cc of crystalloid and made 1320 cc of urine during the cause. for more detailed account, please see operative report. surgery was performed by dr. assisted by dr. . patient was taken to the or to the icu and remained there for 12 days. patient was extubated on postoperative day #3 at which time liver enzymes were greatly improved, ast 82, alt 186, alkaline phosphatase 191, and total bilirubin 6.8 down from 22.1 preoperative. patient was continued on meropenem, linezolid. liver ultrasound duplex was within normal limits. patient was discharged to the floor on postoperative day #11 with continued improvements of lfts: ast of 20, alt 34, and alkaline phosphatase 139, total bilirubin 3.0. at that time, patient was day #14 meropenem, day #41 linezolid. ultrasound duplexes continue to be negative. on postoperative day #16, patient's antibiotics were d/c'd, meropenem and linezolid. the patient was ambulating well. was getting nutrition by p.o. as well as a postpyloric dobbhoff tube, and reported no abdominal pain. on postoperative day #17, patient was deemed well enough to go home with visiting nurse assistance. patient's cholangitis was significant for vancomycin-resistant enterococcus. condition on discharge: stable. discharge status: to home with vna. patient was cleared to go home by pt as well as ot. discharge diagnoses: 1. status post orthotopic retransplantation of liver. 2. alcoholic cirrhosis. 3. portal hypertension. 4. diabetes. 5. cholangitis. 6. renal insufficiency. discharge medications: 1. bactrim single strength p.o. q.d. 2. diflucan 200 mg p.o. q.a.m. 3. valcyte 450 mg p.o. q.d. 4. hydralazine 40 mg q.i.d. 5. protonix 40 mg q.d. 6. prednisone 20 mg q.d. 7. percocet 1-2 tablets p.o. q.4-6h. prn for pain. 8. azathioprine 50 mg q.d. 9. cyclosporin 200 mg p.o. b.i.d. follow-up plans: follow up scheduled with dr. on at 3 p.m. at the transplant center and dr. on at 8:20 a.m. follow-up treatments and frequency: twice weekly laboratories. close followup with dr. and dr. at the transplant center and dry dressings to abdominal wound. patient was also sent out on tube feeding, nepro full strength 60 cc an hour cycled between seven and seven. the patient was also instructed to eat six small meals a day with nutritional supplements. , m.d. dictated by: medquist36 procedure: other endoscopy of small intestine closed (percutaneous) [needle] biopsy of liver endoscopic sphincterotomy and papillotomy
