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: abdominal pain major surgical or invasive procedure: emergent subtotal colectomy, small bowel resection, tube thoracostomy history of present illness: 44m with h/o cll on rituxan tx presented to hospital in nh on with abdominal pain. free air was noted on upright cxr. patient went emergently to the or, where a perforated anterior gastric ulcer was discovered and contained with patch. on , he returned to the or for fascial dehiscence, and was found to be obstructed. he underwent loa with placement of retention sutures. on , his total bilirubin began to rise, reaching a max of 8.6 on . a ct thorax did not reveal any abdominal pathology. he was transferred to for suspicion of cholangitis and possible ercp. on admission, he was on tpn and zosyn (day 15). past medical history: -cll on rituxan -gerd -cholelithiasis s/p cholecystectomy -perforated anterior gastric ulcer s/p exploratory laparotomy & patch, s/p re-exploration & loa social history: married. occasional etoh. family history: unremarkable. physical exam: on admission: 101.7 137 121/64 29 92%2l gen: cachectic neuro: a&ox3, appropriate/attentive, motor tone/power wnl heent: perrl, icteric sclera, nasal mucosa wnl lymph: enlarged cervical, supraclavicular, axillary ln b/l cvs: sinus, clear s1s2, no m/g pulm: symmetry/expansion/effort/palpation wnl, dullness to percussion at l base, absent breath sounds at l base, no wheezes/crackles/pleural rubs/egophony abd: tense, distended, tender, no bowel sounds, +guarding, no rebound, incision with retention sutures ext: trace edema b/l, no clubbing/cyanosis skin: warm, jaundiced pertinent results: on admission: 03:23pm blood wbc-12.2* rbc-3.62* hgb-10.5* hct-31.7* mcv-88 mch-29.1 mchc-33.2 rdw-17.8* plt ct-108* 03:23pm blood neuts-63.5 bands-2.1 lymphs-31.3 monos-2.1 eos-0 baso-0 atyps-1.0* 03:23pm blood pt-12.7 ptt-23.0 inr(pt)-1.1 03:23pm blood glucose-124* urean-16 creat-0.6 na-133 k-4.1 cl-102 hco3-24 angap-11 03:23pm blood alt-50* ast-31 ld(ldh)-161 alkphos-132* amylase-32 totbili-7.8* dirbili-7.1* indbili-0.7 03:23pm blood lipase-13 03:23pm blood albumin-1.8* calcium-7.1* phos-2.9 mg-2.2 06:00pm blood lactate-1.3 ct abd/pelvis (): 1. distal small bowel obstruction. 2. large amount of ascites, some of which is loculated, and minimal free intraperitoneal air. these findings may be related to previous laparotomy. 3. cholelithiasis. 4. innumerable enlarged lymph nodes in the chest, abdomen and pelvis, compatible with known diagnosis of cll. 5. diffuse anasarca. ruq u/s (): limited evaluation of gallbladder due to multiple air containing stones as viewed on ct causing diffuse posterior shadowing. no definite evidence of air within the wall itself. gallbladder scan (): the above findings are consistent with severe liver dysfunction without evidence of common bile duct obstruction. please note the gallbladder and cystic duct cannot be adequately assessed in the setting of liver dysfunction. mrcp (): intra- and extra-hepatic bile ducts appear unremarkable. there is no evidence of choledocholithiasis. 2. gastric wall thickening and hyperenhancement likely representing post-operative changes and possible ongoing ulcer disease. 3. pleural effusion and moderate ascites. 02:15am blood lipase-10 03:44pm blood alt-35 ast-16 alkphos-90 totbili-12.6* ugi/sbft (): no evidence of extraluminal extravasation of contrast on this study limited by patient intolerance of prone positioning. 2. free passage of contrast through the stomach into the duodenum. 3. thickened folds of the gastric body and limited gastric distensibility. rue u/s (): 1. nonocclusive thrombus present within the right basilic vein. 2. right internal jugular vein not directly identified. followup study may be performed is there is clinical concern for venous occlusion. 3. cervical lymphadenopathy. pathology (): i. ileocolectomy (a-l): 1. pseudomembranous colitis, diffuse, extending to distal resection margins. 2. malignant lymphoma involving ileum and mesenteric lymph nodes. the case will be reviewed by hematopathology with their report in an addendum. 3. organizing peritoneal hemorrhage. ii. left colon (m-r): 1. diffuse pseudomembrane colitis, extending to both margins. 2. hemorrhage and fibrotic serosa and mesocolic fat. 3. no tumor. iii. sigmoid colon (s-u): 1. mild pseudomembranous colitis, extending to the margins. 2. fibrosis and hemorrhage of serosa and mesocolic fat. 3. no tumor. iv. small intestine, partial resection (v-y): 1. unremarkable small intestinal mucosa. 2. hemorrhage and fibrosis of peritoneum. 3. no tumor. ct head (): 1. no intracranial hemorrhage, mass effect, or abnormal enhancement. 2. mucosal thickening in multiple paranasal sinuses with features as described above. ct chest/abd/pelvis (); 1. bilateral airspace consolidation with moderate pleural effusion and atelectasis, suggestive of ards. 2. massive mediastinal, hilar, axillary, mesenteric, and retroperitoneal lymphadenopathy due to chronic leukemia. 3. two loculated fluid collections versus abscesses, one at the left flank and one anterior to the rectum, which may be communicating. 4. marked wall thickening throughout the colon, suggestive of pancolitis. edema in the peritoneal fat and small amount of ascites. 5. gallstones. on day of expiration: 03:00am blood wbc-56.6* rbc-3.99* hgb-12.5* hct-37.0* mcv-93 mch-31.4 mchc-33.8 rdw-15.5 plt ct-57* 03:00am blood pt-15.6* ptt-37.3* inr(pt)-1.4* 03:00am blood fibrino-318 03:00am blood glucose-113* urean-26* creat-0.8 na-145 k-5.8* cl-119* hco3-23 angap-9 03:00am blood calcium-6.7* phos-5.5* mg-1.9 07:44am blood type-art po2-42* pco2-78* ph-7.06* caltco2-24 base xs--11 06:34am blood lactate-3.6* 06:34am blood o2 sat-74 brief hospital course: patient was admitted to the and started on vanc/. he was made npo with ivf. a fever (tmax 101.4) work-up was initiated. a cxr demonstrated a lll infiltrate. all urine and blood cultures drawn throughout this hospital stay were ultimately negative. surgery was consulted. an ngt was placed with immediate bilious output and symptomatic relief. patient was transferred to sicu on hd 2. he continued to be febrile (tmax 101.2) and tachycardic. a ct demonstrated distal sbo and cholelithiasis. he was not a candidate for ercp given his recently laparotomies x 2 and perforated ulcer repair. flagyl was added. on hd 3, he continued tachycardic, but his temperature decreased slightly; tmax was 100.4. hida and mrcp were performed without evidence for cbd obstruction. tpn was started. on hd 4, tmax was 101.7 and he remained tachycardic. diuresis was begun with iv lasix. on hd 5, tmax was 101.5. he was still tachycardic. all antibiotics were d/c'd and the patient was transferred to the floor. on hd 6, tmax decreased to 100, but he was still tachycardic. he was transferred back to the sicu for progressive dyspnea (rr in mid 30s) and labored breathing, abg 7.53/34/50/29/5. lasix gtt was started. he failed to improve clinically despite non-rebreather fm and bipap; he was later intubated. an ugi with sbft failed to demonstrate a leak. his ngt was d/c'd. on hd 7, he continued to be febrile and tachycardic. he required increasing amounts of pressors to maintain his bp. lasix was d/c'd. vanc/zosyn were started empirically. ngt was replaced. cvl was replaced. he underwent ct torso which demonstrated pancolitis, ards, and large l pleural effusion. as his wbc rose to 57 and he had new-onset diarrhea, it was felt to be indicative of fulminant c.diff colitis. he underwent subtotal colectomy emergently. a small bowel resection and tube thoracostomy were also performed. overnight, he became hypotensive, hypoxemic, and acidemic. he continued to require 3 pressors. the following day, he continued to be unstable, requiring massive fluid intake to maintain his pressures (despite multiple pressors). a family meeting was held in the afternoon. the patient was made cmo. all pressors were d/c'd. he expired at 13:35. medications on admission: zosyn, protonix, zofran, morphine pca discharge medications: patient expired. discharge disposition: expired discharge diagnosis: c. difficile pancolitis, septic shock, hyperbilirubinemia, partial sbo, ards discharge condition: expired. discharge instructions: expired. followup instructions: expired. procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours parenteral infusion of concentrated nutritional substances insertion of endotracheal tube non-invasive mechanical ventilation insertion of other (naso-)gastric tube other incision of pleura diagnoses: other postoperative infection unspecified pleural effusion congestive heart failure, unspecified severe sepsis other specified intestinal obstruction other malignant lymphomas, unspecified site, extranodal and solid organ sites hemorrhage complicating a procedure other specified procedures as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure acute respiratory failure intestinal infection due to clostridium difficile septicemia due to anaerobes other and unspecified coagulation defects chronic lymphoid leukemia, without mention of having achieved remission disruption of external operation (surgical) wound
