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: patient recorded as having no known allergies to drugs attending: chief complaint: "feeling unwell" major surgical or invasive procedure: --central venous line placement history of present illness: mr. is a 58 year old man with history of end-stage liver disease status-post liver transplant, with recurrence of his hepatitis c, who presents today with nausea, vomiting, diarrhea, and overall feeling unwell. he reports that for the last 3-4 weeks, he has had on-going watery diarrhea. he was admitted to on the - service from until the 8th for work-up of the diarrhea. a discharge summary is not yet available, however he reports that a ct scan was completed that demonstrated "colitis," for which he was treated with ciprofloxacin and metronidazole, having finished a course yesterday. during that admission, stool o&p was negative, as was c. difficile assay. of note, around that time, he had been tapering off methadone and started on clonidine for his withdrawal symptoms. he followed up with his liver physician, . , on , at which time he reported his symptoms had improved. at that visit, the plan was to resume ribavirin and interferon for treatment of his recurrent hepatitis c after transplant; these had been stopped earlier this year due to concerns over suicide ideation. today he reports that his diarrhea got slightly better at some points over the last weeks, but has worsened over the last few days. he is unable to quantify, but states he has had "too many to count" when asked number of bowel movements. they have been watery without blood or melena. he has also had emesis (non-bloody and non-bilious) for the last two days. he reports poor po intake and that he vomitted after attempting to eat soup yesterday. he has been urinating less as well. he had some lightheadedness and dizziness today that prompted him to seek medical attention along with feeling overall very poorly. in the ed, initial vital signs were: temperature of 98.0, blood pressure of 71/40, heart rate of 88, respiratory rate of 18, and oxygen saturation of 99% on room air. during his time in the ed, he received three liters of normal saline, 1 gram of vancomycin, and 4.5 grams of zosyn. during his ed stay, his systolic blood pressure ranged from 74-109. levophed was written for, but never started given response of blood pressure to ivf. a chest x-ray was unremarkable, and an abdominal ultrasound did not demonstrate any ascites. upon arrival to the icu, he reported that he was very hungry and wanted to eat. he stated he fele the best he had felt in days. past medical history: - status-post olt liver transplant for hcv cirrhosis and hepatocellular carcinoma - hepatitis c: recurred after transplant - hypertension - diabetes mellitus - bph -

post liver transplant with patent hepatic vasculature. 2. no definite focal liver lesion seen; however, multi-phase mri/ct are more sensitive for focal liver lesions and can be obtained if clinically warranted. cxr (): status post right ij central venous line placement with tip in the upper svc. no pneumothorax. brief hospital course: 1.) hypotension/shock upon admission to the icu, the patient had received three liters of ivf, producing a sbp>100. given the patient's history and response to ivf, the cause was most likely hypovolemic shock given gi losses and poor po intake. also considered (given immunocompromised host) were infections, as well as adrenal insufficiency and cardiogenic) cuases. aggressive fluid resuscitation was continued in the icu with a goal map>65 and uop>50cc/hr. lisinopril, clonidine, terazosin were held. patient was continued on vancomycin and zosyn since the ed, with metronidazole added for empiric coverage of c. difficile and anaerobic organisms (seems unlikely to need coverage for msra given lack of indwelling lines, no pulmonary/skin symptoms). flagyl was removed due to redundant coverage. the patient remained hypotensive throughout the stay. on the patient was transferred to 10. he was observed over night and his blood pressure ranged from 107-115/69-87. at the time of discharge his bp was 131/86. he was asymptomatic overnight. his clonidine was restarted at his home dose. his lisnopril was held. 2.) diarrrhea, nausea, vomiting patient had long history of nausea, vomiting, and diarrhea (for about 3-4 weeks prior to admission). initially felt to possibly be viral gastroenteritis versus symptoms from methadone withdrawal. previous imaging showed evidence of jejunitis. patient was started on broad coverage with vanc and zosyn in ed. flagyl was added in icu. c. difficile was negative, so flagyl was stopped. he did resume interferon/ribavirin recent to admission, but the symptoms began previous to this. o&p, viral cultures, and microsporidium/crytposporidium were sent out and pending upon discharge. patient was beginning to advance diet towards a brat diet upon discharge. on morning of discharge patient reported improvement in diarrheal symptoms. while an infectious cause is possible, the fact that c diff and fecal culture were negative makes infectious diarrhea less likely. it is more likely that the syptoms were due to his recent cessation of methadone. he was discharged home with a script for loperamide. 3.) status-post liver transplant with recurrent hcv patient was continued on home regimen of immunosuppressives and prophylaxis. ribavirin and interferon continued. liver doppler was negative for focal lesions. afp was pending at time of dischage. patient is scheduled to follow up with transplant team in two weeks time. 4.) depression hcv therapy was stopped due to suicide ideation, though per last omr note, was cleared to resume therapy. patient continued on home dose of citalopram throughout stay. 5.) diabetes mellitus continued on home regimen of insulin. medications on admission: - aspirin 81 mg - bactrim 400 mg-80 mg daily - citalopram 40 mg - clonidine 0.1 mg - fish oil - gabapentin 600 mg qhs
