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: allergies: penicillins attending: chief complaint: end stage liver disease for orthotopic liver transplantation major surgical or invasive procedure: orthotopic liver transplant s/p hepatojej and hepatic artery to splenic a conduit for ha anastomosis history of present illness: is a 61-year-old man with hepatocellular carcinoma and liver cirrhosis who is being admitted for orthotopic liver transplant. he was well until about three or four years ago when an ultrasound demonstrated liver cirrhosis. this was presumably due to fatty liver disease in association with a markedly elevated triglycerdes of 25 years. patient was referred to in for work-up of bleeding esophageal varices which were banded in at an outside hospital. in , a ruq ultrasound was obtained which showed a 2-cm lesion in left lobe of liver. mri demonstrated two highly suspicious liver masses that could represent hepatocellular. on mr. radiofrequency ablation and biopsy of two left liver lobe lesions. he was added to the waiting list with a calculated meld score of 8; an additional 14 points were awarded due to the presence of hepatocellular carcinoma, for a total meld score of 22. subsequent, post-ablative ct scans have shown no recurrence of cancer. patient is hepatitis b negative. of note, several egds have been performed with the most recent on which demonstrated: three cords grade i varices at the lower third of the esophagus ulcerated polyps in the antrum (biopsy) thick gastric folds normal mucosa in the duodenum otherwise normal egd to third part of the duodenum past medical history: cirrhosis likely from fatty liver esophageal varices diverticulosis renal stones gastroesophageal reflux disease (gerd) type 2 diabetes perianal cyst hyperlipidemia hypertension skull fracture at age 6 anemia social history: radiochemist in a nuclear power station. lives with his family in , ma. history of 1 etoh drink/day until when he stopped. ex-smoker who quit x 25 years. no ivda. family history: his dad died of some sort of liver disease but no liver cancer. he is unsure of any details of this. his mom had a myocardial infarction and stroke at question of age 59, and otherwise his family is healthy. physical exam: vs: 98.7 91 148/82 20 98ra fs: 141 gen: aaox3, nad, pleasant, anicteric heent: eomi, ncat, perrl pulm: cta bilaterally, no wheezes or crackles cards: rrr, normal s1/s2, no m/r/g abd: soft/nontender/nondistended, liver was nonpalpable, spleen non palpalpable, no abnormal masses gu: no cva tenderness extremities: move extremities spontaneously, no le edema, warm, well perfused neuro: grossly intact pertinent results: 09:56am blood wbc-5.2 rbc-3.80* hgb-11.6* hct-33.8* mcv-89 mch-30.5 mchc-34.2 rdw-14.3 plt ct-108* 09:56am blood pt-14.3* ptt-29.5 inr(pt)-1.2* 09:56am blood glucose-145* urean-9 creat-0.7 na-144 k-3.5 cl-110* hco3-20* angap-18 09:56am blood alt-49* ast-57* alkphos-108 totbili-1.3 brief hospital course: mr. had an orthotopic livet transplant. first post operative day his duplex did not show good flow in the hepatic artery . it was repeated the following day and the duplex failed to demonstrate intrahepatic arterial flow in the left and right lobes, nor any flow in the porta with only a partial signal seen well away from the liver hilum, suggesting severe stenosis or oclusion. portal and hepatic venous flow was normal . he was taken back to the operating room procedure done: 1. exploratory laparotomy. 2. revision of hepatic artery anastomosis. 3. roux-en-y hepaticojejunostomy. 4. liver biopsy. 5. intraoperative ultrasound. post op he was on a heparin gtt. he did well. was extubated with problem and transferred to the floor. events on the floor were 1) heparin gtt was transitioned to coumadin 2) slowly drifting down of hct so he was transfused a couple of units prbc after much discussion it was decided to stop the anticoagulation as the hepatic artery anastomosis was revised 3) he had a hepatico jejunostomy so he was npo for 3-4 days after which his diet was slowly advanced 4) he received hbig vaccines in addition to monitoring hep b ab titers 5) his immunosuppresive medication was managed per protocol. 6) he had some loose bowel movement but cdiff was negative. medications on admission: meds: metformin, iron, glyburide, multivitamin, lactulose, rifaximin, propranolol, and omeprazole. discharge medications: 1. prednisone 5 mg tablet sig: four (4) tablet po daily (daily). 2. tamsulosin 0.4 mg capsule, sust. release 24 hr sig: one (1) capsule, sust. release 24 hr po hs (at bedtime). 3. trimethoprim-sulfamethoxazole 80-400 mg tablet sig: one (1) tablet po daily (daily). 4. lamivudine 100 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 5. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 6. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*30 tablet(s)* refills:*0* 7. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 8. mycophenolate mofetil 500 mg tablet sig: two (2) tablet po bid (2 times a day). 9. valganciclovir 450 mg tablet sig: two (2) tablet po daily (daily). 10. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 11. fluconazole 200 mg tablet sig: two (2) tablet po q24h (every 24 hours). 12. tacrolimus 1 mg capsule sig: four (4) capsule po q12h (every 12 hours) for 2 doses: dosage dtermined by levels. 13. insulin lispro 100 unit/ml solution sig: as directed subcutaneous every six (6) hours: humalog sliding scale. disp:*5 * refills:*2* discharge disposition: home with service facility: vna discharge diagnosis: 61m with hcc and cirrhosis s/p olt ;
