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: no drug allergy information on file attending: chief complaint: melena and brbpr major surgical or invasive procedure: egd history of present illness: 46m h/o non-bleeding gastric ulcers 2 years ago, awoke at 3am on the day of presentation and had a large jet-black loose stool. on rising from the toilet, he felt lightheaded, and fell to the floor. no head trauma, no

his bp was 109/71, hr 105, and was found to have a hct of 35 (unknown baseline), plt 439, inr 1.0. ecg with incomplete rbbb but no ischemic changes. ng lavage was done, which demonstrated coffee-grounds, no active bleeding. he was given protonix 40mg iv, 2l ns, and transferred to since no icu beds were available at nwh. in the ed at , initial vs were t 98.0f, bp 117/68, hr 98, rr 10, sao2 99% ra. his ngt was in place and drained yellow fluid with no blood. his hct was found to be 32.3, 31.4 on recheck. he had a total of 10 episodes of brbpr, none between 12pm and 7pm. two large bore pivs were placed, ns was started wide open, and 2u prbc were t&c'ed. an additional 40mg iv protonix was given, and a protonix drip was started at 8mg/hr. gi was consulted, who agreed with icu admission for monitoring, and plan to perform egd in the morning unless becomes unstable. . past medical history: non-bleeding gastric ulcers, diagnosed by egd. was on protonix for 1 month, after which he felt better, and this was d/c'ed. he does not now his h. pylori status, and has had no epigastric pain since social history: married, works as production manager. non-smoker, drinks 3-4 drinks each night on the weekends. family history: nc physical exam: vitals: 37.1 91 122/65 99%ra general: well appearing in nad heent: ncat neck: no jvp, strong carotid pulse lungs: cta b/l cardiac:

hgb-11.1* hct-31.4* findings: esophagus: normal esophagus. stomach: mucosa: localized erosion of the mucosa was noted in the antrum. these findings are compatible with non-steroidal induced gastritis. cold forceps biopsies were performed to assess for h. pylori at the stomach antrum. duodenum: excavated lesions two non-bleeding ulcers was found in the first part of the duodenum. the larger, more distal ulcer, measured approximately 1.5 cm and had a central dark spot indicative of prior bleeding. there was extensive duodenitis. brief hospital course: gi bleeding: patient was initally admitted to the intensive care unit for close monitoring in the setting of active gi bleed. patient received 2 units of blood transfusions, ivf, and serial hct monitoring. the patient remained hemodyamically stable, and his hct held steady. he was placed on a protonix gtt while in the icu. due to the patients stability, he was transfered to the floor. he remained npo, and the protonix gtt was changed to iv bid protonix. on the third day of hospitalization, the patient underwent an egd, which showed two non-bleeding ulcers in the first part of the duodenum. the larger, more distal ulcer, measured approximately 1.5 cm and had a central dark spot indicative of prior bleeding. there was extensive duodenitis. cold forceps biopsies were performed to assess for h. pylori at the stomach antrum. the patient tolerated procedure well. he was discharged on protonix po bid x one month, then daily. he was instructed to avoid nsaids. he will be contact by gi in regard to the biopsy results. medications on admission: none discharge medications: 1. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po twice a day for 1 months: after one month switch to once a day. disp:*60 tablet, delayed release (e.c.)(s)* refills:*2* discharge disposition: home discharge diagnosis: upper gi bleed w/ duodenal ulcers and gastritis discharge condition: stable discharge instructions: you are being discharged from the hospital after admission for a gastrointestinal bleed. you underwent a egd, which showed two non-bleeding ulcers was found in the first part of the duodenum. the larger, more distal ulcer, measured approximately 1.5 cm and had a central dark spot indicative of prior bleeding. avoid all nsaids and -2 inhibitors. take tylenol for pain. take a
