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: mr. is a 45-year-old male with a past medical history remarkable for chronic relapsing pericarditis secondary to severe variant rheumatoid arthritis. the patient has been experiencing severe pleuritic chest pain which had been controlled on 10 mg of prednisone; however, this had recently increased to 20 mg to control these recurrent flares. since the symptoms stemming from the relapsing pericarditis has required the use of prednisone while other symptoms such as aching in the hands and feet have been well controlled on colchicine and methotrexate, the cardiothoracic surgery service was consulted to evaluate this patient for pericardiectomy. past medical history: 1. severe variant rheumatoid arthritis. 2. gastritis. 3. history of helicobacter pylori. 4. status post back surgery. medications on admission: (medications at home included) 1. prednisone 7.5 mg p.o. once per day. 2. methotrexate 15 mg p.o. every week. 3. colchicine 0.6 mg p.o. twice per day 4. duragesic patch 50 as needed. 5. oxycontin 40 mg p.o. four times per day as needed (for pain). 6. centrum. 7. nexium. 8. stool softeners. allergies: pertinent laboratory values on presentation: pertinent laboratories as of revealed white blood cell count was 10.5, hematocrit was 30.8, and platelets were 175. sodium was 143, potassium was 4.4, chloride was 107, bicarbonate was 27, blood urea nitrogen was 11, creatinine was 0.7, and blood glucose was 120. magnesium was 2.3. physical examination on presentation: physical examination revealed vital signs with a temperature of 99.2, heart rate was 80 (sinus), blood pressure was 140/72, respiratory rate was 18, and oxygen saturation was 96% on room air. the patient is a well-developed and well-nourished male in no apparent distress. sclerae were anicteric. mucous membranes were moist. no evidence of oral ulcers. no evidence of cervical lymphadenopathy. cranial nerves ii through xii were intact. the chest was clear to auscultation bilaterally. the sternal dressing was intact. no evidence of extending erythema. no serosanguineous drainage was noted. the sternum showed no signs of click to palpation. cardiovascular examination revealed a regular rate and rhythm. no murmurs, no rubs, and no click noted. the abdomen was soft, nontender, and nondistended. positive bowel sounds. no evidence of inguinal lymphadenopathy. no hepatosplenomegaly was noted. extremity examination revealed no evidence of edema. no rash was noted. hospital course: the patient is a 45-year-old male with a long history of severe variant rheumatoid arthritis who underwent a subtotal pericardiectomy for recurrent pericarditis. the patient's intraoperative course as well as postoperative course were uncomplicated. the patient was taken to the cardiothoracic surgery recovery unit immediately postoperatively for close monitoring. the patient was promptly extubated. the patient maintained good oxygen saturations status post extubation and remained in a normal sinus rhythm while maintaining good pressure without any pressors. by postoperative day two, the patient's condition continued to advance; demonstrating ambulation greater than five minutes without evidence of shortness of breath. by postoperative day three, the patient achieved proper physical therapy status criteria for discharge and the decision was made to discharge the patient in good condition from the hospital without services. condition at discharge: condition on discharge was good. discharge status: discharge status was to home. discharge diagnoses: status post subtotal pericardiectomy. medications on discharge: 1. prednisone 7.5 mg p.o. once per day. 2. aspirin 325 mg p.o. once per day. 3. metoprolol 25 mg p.o. twice per day. 4. fentanyl patch. 5. oxycodone 80 mg p.o. twice per day. discharge instructions/followup: 1. the patient was requested to follow up with dr. in four weeks after discharge. 2. the patient was to follow up with dr. in one to two weeks. , m.d. dictated by: medquist36 d: t: 15:45 job#: procedure: pericardiectomy diagnoses: esophageal reflux other specified diseases of pericardium polyarticular juvenile rheumatoid arthritis, chronic or unspecified
