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: history of present illness: patient is a 57-year-old male with a past medical history significant for end-stage renal disease secondary to type 2 diabetes mellitus. he also has a history of peripheral vascular disease and had a left above the knee amputation done as a result of a gunshot wound suffered in the war in as well as an aortobifemoral bypass graft performed approximately 20 years ago. the patient does have a history of known carotid artery disease and coronary artery disease, and had a four vessel coronary artery bypass graft performed in . the patient presents to this institution today for elective living related renal transplantation from his brother, . at the time of admission, the patient denies fever, chills, nausea, vomiting, anorexia, diarrhea, and constipation. he does state that he does have mild peripheral edema in the right lower extremity at baseline. past medical history: 1. end-stage renal disease. 2. insulin dependent-diabetes mellitus. 3. hypertension. 4. coronary artery disease status post cabg. 5. peripheral vascular disease status post aortobifemoral bypass graft. 6. history of traumatic left above the knee amputation. 7. history of osteomyelitis. 8. history of nephrolithiasis. medications: 1. neurontin 200 mg p.o. t.i.d. 2. metoprolol 50 mg p.o. t.i.d. 3. clonidine 0.2 mg p.o. b.i.d. 4. hydrochlorothiazide 12.5 mg p.o. q.d. 5. tums 1000 mg p.o. q.i.d. 6. ativan 2 mg p.o. q.h.s. prn. 7. aranesp 25 mcg q week. 8. norvasc 5 mg p.o. b.i.d. 9. lasix 160 mg p.o. q.d. 10. lipitor 80 mg p.o. q.d. 11. aspirin 325 mg p.o. q.d. 12. vitamin e 400 units q.d. 13. humalog insulin-sliding scale. 14. insulin glargine 18 units subcutaneously q.h.s. physical exam: vital signs: temperature 98.3, blood pressure 138/70, pulse 76, respiratory rate 18, and oxygen saturation 100% on room air. in general, the patient is a healthy appearing white male, who is comfortable and in no apparent distress. his oropharynx is clear. his mucous membranes are moist. his sclerae are anicteric. the neck is supple without lymphadenopathy or jvd. his heart was regular rate and rhythm without murmurs. his lungs are clear to auscultation bilaterally. his abdomen is soft, nontender, and nondistended with no palpable masses. his left lower extremity reveals an above the knee amputation. his right lower extremity has 1+ pedal edema with a 2+ femoral pulse and capillary refill less than two seconds to all digits. hospital course: on the date of admission, patient was taken to the operating room, where he underwent a living related kidney transplant. the surgery was complicated by a 6 unit intraoperative blood loss along with thromboembolism of the right superficial femoral artery requiring groin exploration and embolectomy by the vascular surgery service. the postoperative hematocrit was 32.8 with a creatinine of 4.1 and a potassium of 5.3. the patient was monitored in the recovery room until postoperative day #2 at which time he was transferred to the regular hospital floor. the patient had adequate urine output postoperatively making 7 liters on postoperative day #1, 4 liters on postoperative day #2, and 3 liters on postoperative days #3 and four. a renal transplant ultrasound was performed postoperatively, which demonstrated normal arterial and venous flow without hydronephrosis or leak. the - drain did, however, put out a significant amount on postoperative day #2. the specimen was sent for a creatinine level, which returned at 2.7. on postoperative day #3, the drain output was 350 cc and #4 was 600 cc. at this time, a renal scan was performed in the nuclear medicine department, which did not demonstrate a leak. the patient was doing well at this time with stable hematocrits and urine output. he was ambulating with the assistance of physical therapy. his immunosuppressant regimen included three doses of antithymocyte globulin along with cellcept, prograf, and a prednisone taper. the patient's right lower extremity was warm throughout his stay with dopplerable pulses of the posterior tibial and anterior tibial arteries. his foley catheter was removed on postoperative day #6, and he was able to void without difficulty. on postoperative day #7, the - drain was removed, and on postoperative day #8, the patient was discharged to home with the visiting nurse with blood draws and physical therapy. the creatinine at the time of discharge was 1.2. discharge condition: good. discharge disposition: the patient was discharged to home with visiting nurse with wound care, blood draws, and physical therapy. discharge diagnoses: 1. end-stage renal disease. 2. status post living related renal transplantation. 3. status post right superficial femoral artery thrombectomy. 4. status post traumatic left above the knee amputation. 5. peripheral vascular disease. 6. status post aortobifemoral bypass graft. 7. insulin dependent-diabetes mellitus. 8. coronary artery disease status post coronary artery bypass graft. 9. hypertension. 10. history of osteomyelitis. 11. history of nephrolithiasis. discharge medications: 1. bactrim single strength one tablet p.o. q.d. 2. valganciclovir 450 mg p.o. q.d. 3. colace 100 mg p.o. b.i.d. 4. neurontin 200 mg p.o. t.i.d. 5. metoprolol 50 mg p.o. t.i.d. 6. clonidine 0.2 mg p.o. b.i.d. 7. lorazepam 1-2 mg p.o. q.h.s. prn. 8. nystatin 5 ml p.o. q.i.d. 9. percocet 5/325 1-2 tablets p.o. q4-6h prn pain. 10. protonix 40 mg p.o. b.i.d. 11. cellcept mg p.o. q.i.d. 12. lasix 20 mg p.o. b.i.d. 13. prednisone 20 mg p.o. q.d. 14. amlodipine 10 mg p.o. b.i.d. 15. tacrolimus 5 mg p.o. b.i.d. 16. insulin glargine 20 units subcutaneously q.h.s. 17. humalog insulin-sliding scale as directed. follow-up plans: the patient was instructed to followup with dr. in the transplant center in approximately 1-2 weeks for staple removal. he was also instructed to followup with dr. from the department of vascular surgery in two weeks. he will be having his blood drawn every monday and thursday with a cbc, chem-7, and tacrolimus levels to be checked and faxed to the transplant center for monitoring. discharge instructions: patient was instructed to followup sooner if he develops fevers greater than 101.5 f, vomiting, severe abdominal pain, or if he had any other questions or concerns. , m.d. dictated by: medquist36 procedure: other revision of vascular procedure incision of vessel, lower limb arteries other kidney transplantation open biopsy of kidney diagnoses: nephritis and nephropathy, not specified as acute or chronic, in diseases classified elsewhere coronary atherosclerosis of native coronary artery hemorrhage complicating a procedure peripheral vascular complications, not elsewhere classified other complications due to other vascular device, implant, and graft diabetes with renal manifestations, type ii or unspecified type, not stated as uncontrolled above knee amputation status
