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: codeine attending: chief complaint: brbpr major surgical or invasive procedure: colonoscopy history of present illness: 81 y.o. male with history of colonic adenomatous polyp and grade 2 esophagitis in who presents with a chief complaint of hematochezia x 1 day. patient reports up to 6 grossly bloody, loose bms with ? melena and diaphoresis, but no hematemesis, abdominal pain, fevers/chills, n/v, lightheadedness, cp, sob, palpitations. given the ongoing symptoms, patient presented to the ed for further evaluation. . in the ed, vitals were: t - 97.4, bp - 111/57, hr - 90, rr - 18, o2 - 99% ra. hct was 26.7, down from 36.3 in in . ngl was negative, however, there was no bilious return. though patient was hemodynamically stable, he was admitted to the icu for close observation and gi follow-up. past medical history: hypertension chronic renal insufficiency (baseline of 1.8 - 2) cml gout chronic low back pain carpal tunnel syndrome bph social history: patient denies tobacco or illicit drug use. he reports occasional alcohol consumption. he is a tax attorney, married. family history: nc physical exam: vitals: t - 97.2, bp - 124/65, hr - 78, rr - 18, o2 - 95% ra general: awake, alert, nad, resting comfortably in bed heent: nc/at; perrla, eomi; op clear, nonerythematous neck: supple, no lad chest/cv: s1, s2 nl, no m/r/g appreciated lungs: ctab abd: soft, nt, nd, + bs rectal: guaiac positive, maroon colored stool ext: no c/c/e neuro: grossly intact skin: no lesions pertinent results: 11:50pm blood wbc-15.7* rbc-2.52* hgb-9.1*# hct-26.7*# mcv-106* mch-36.3* mchc-34.2 rdw-18.1* plt ct-484* 11:50pm blood glucose-208* urean-39* creat-2.4* na-140 k-6.2* cl-107 hco3-21* angap-18 06:45am blood calcium-8.3* phos-3.0 mg-1.8 brief hospital course: 81 y.o. male with history of colonic polyps and esophagitis who presented with hematochezia. . # hematochezia: pt presented with hematochezia and hct of 26.7. had a h/o diverticulosis and polyps which could have been the source of the bleed. patient intially admitted to the micu. hct slowly trended down and pt initially reluctant to get transfusions, but eventually agreed. was prepped and had colonoscopy that showed diverticulosis of the entier colon, irregular site of previous polypectomy and otherwise nl colonoscopy to cecum. prep was noted to be poor. he was hemodynamically stable, with stable hct and called out to the floor. he then underwent an egd, which showed a single superficial non-bleeding 5mm ulcer was found on the posterior wall of the antrum. no blood was found in the upper tract, and the ulcer showed no stigmata of bleeding. this lesion is an unlikely cause of hematochezia. it seems probably that the event that precipitated this admission was a diverticular bleed. as his colonoscopy prep was poor, and he had a previous polyp, he should return for an elective colonoscopy sometime later this year. with his previous history of esophagitis and the current finding of an ulcer, it may be most prudent to continue acid reduction therapy indefinitely. . # chronic renal insufficiency: increased at admit at 2.4 from baseline of 1.8 - 2, possibly due to hypovolemia from gib. improved with fluids and transfusions to baseline. . # leukocytosis/thrombocytosis: no localizing symptoms or evidence of infection. ua was negative. patient does have myeloproliferative disease and wbc has been elevated in the past, though more recently was normal. he was monitored for fevers and remained afebrile. . # cml: no active issues> he was continued on hydrea . # gout: he was continued on renally dosed allopurinol. . # bph; alpha blockers held in the setting of gib . # chronic pain: he received tylenol prn andlow-dose narcotics prn for continued pain as bp tolerated . # code status: full medications on admission: allopurinol finasteride hydrea ambien discharge medications: 1. allopurinol 100 mg tablet sig: one (1) tablet po daily (daily). 2. hydroxyurea 500 mg capsule sig: one (1) capsule po daily (daily). 3. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 4. finasteride 5 mg tablet sig: one (1) tablet po once a day. 5. zolpidem 5 mg tablet sig: one (1) tablet po hs (at bedtime) as needed. discharge disposition: home discharge diagnosis: primary diagnosis: diverticular bleed secondary dx: acute renal failure chronic renal insufficiency myeloproliferative disease gout bph discharge condition: stable discharge instructions: you are being discharged from the hospital after admission for gastrointestinal bleed. you required blood transfusion, and rbc count has since held stable. colonoscopy yesterday was normal. today's upper endoscopy today found a single superficial non-bleeding 5mm ulcer. no blood was found in the upper tract, and the ulcer showed no stigmata of bleeding. this lesion is an unlikely cause of your bleeding. it seems probably that the event that precipitated this admission was a diverticular bleed. your colonoscopy prep was poor, and he as you had a previous polyp, you should return for an elective colonoscopy sometime later this year. with a previous history of esophagitis and the current finding of an ulcer, it may be most prudent to continue acid reduction therapy indefinitely. followup instructions: you should follow up with your pcp at 130pm you have a repeat colonoscopy set up for at 8am please call ( with questions. information will be mailed to you in the mail. procedure: other endoscopy of small intestine colonoscopy transfusion of packed cells diagnoses: obstructive sleep apnea (adult)(pediatric) acute posthemorrhagic anemia acute kidney failure, unspecified hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage i through stage iv, or unspecified gout, unspecified hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) chronic kidney disease, unspecified gastric ulcer, unspecified as acute or chronic, without mention of hemorrhage or perforation, without mention of obstruction hypovolemia diverticulosis of colon with hemorrhage chronic myeloid leukemia, without mention of having achieved remission personal history of colonic polyps essential thrombocythemia 

Answer: The patient is high likely exposed to
