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: rituxan attending: chief complaint: rituxan desensitization major surgical or invasive procedure: none history of present illness: 84m history of lymphoplasmacytic lymphoma/splenic lymphoma s/p 4 weekly doses of rituxan in , and recent bendamustine (c2d1 on ), who had recent admission for rituximab cycle 2 on complicated with rituximab reaction manifesting as dyspnea. pt now being admitted to icu for close monitoring during rituximab desensitization prior to receiving cycle #3 rituximab. . on arrival to the icu, pt is comfortable. he reports 1 episode of diarrhea today, no further episodes. feels well otherwise. no shortness of breath, no cough, does note mildly increased pedal edema. past medical history: past oncologic history: patient and his nephew report several years of low grade pancytopenia and progressive fatigue. in the last year fatigue has reached the point that the patient has difficulty with some activities of daily living such as shoveling snow and ambulating outside of his house. patient also reports a recent weight loss but denies fevers, chills, or night sweats. given the progression of symptoms and counts a bone marrow biopsy was performed which demonstrated a monoclonal b cell population consistent with a lymphoplasmacytic lymphoma. patient underwent 4 weekly doses of rituximab in , with improvement in splenomegaly, counts, and energy, but he had relative rapid recurrence of disease. he was started on r-bendamustine 80mg/m2 x 2days on . other past medical history: - hypertension - hyperlipidemia - dementia, patient reports trouble with memory - bph - anemia - gerd - back pain - peripheral neuropathy - inguinal hernia - ventral hernia - venous stasis past surgical history: - cholecystectomy - excision of scalp skin cancer social history: single, never married, no children. lives alone in . previously worked in communication. nephew is hcp; this nephew has severe psychiatric illness and patient reports he cares for him. denies tobacco, etoh, illicits. family history: mother d. age , father d. age 54 of presumed pe. twin brother with cancer. no other cancers in the family. physical exam: vitals: t 96.1, hr 68, rr 20, 98%ra, 119/55 general: alert, oriented, no acute distress heent: sclera anicteric, mmm, oropharynx clear neck: supple, jvp not elevated, no lad lungs: crackles bilaterally r>l cv: regular rate and rhythm, normal s1 + s2, no murmurs, rubs, gallops abdomen: soft, non-tender, non-distended, bowel sounds present, no rebound tenderness or guarding, no organomegaly gu: no foley ext: warm, well perfused, 2+ pulses, no clubbing, cyanosis or edema pertinent results: 04:30am blood wbc-1.4* rbc-3.40* hgb-9.5* hct-29.2* mcv-86 mch-28.1 mchc-32.7 rdw-16.4* plt ct-13*# 04:30am blood neuts-84.7* lymphs-10.8* monos-3.8 eos-0.5 baso-0.2 04:30am blood glucose-134* urean-26* creat-1.2 na-141 k-3.6 cl-101 hco3-27 angap-17 04:30am blood alt-12 ast-26 ld(ldh)-594* alkphos-117 totbili-0.8 04:30am blood albumin-3.5 calcium-8.4 phos-4.1 mg-1.9 echo overall left ventricular systolic function is mildly depressed (lvef= 45 %). the right ventricular cavity is dilated with focal hypokinesis of the apical free wall. the mitral valve leaflets are mildly thickened. there is no mitral valve prolapse. moderate (2+) mitral regurgitation is seen. moderate tricuspid regurgitation is seen. there is severe pulmonary artery systolic hypertension. there is a moderate sized pericardial effusion. there are no echocardiographic signs of tamponade. no right atrial or right ventricular diastolic collapse is seen. echocardiographic signs of tamponade may be absent in the presence of elevated right sided pressures. compared with the findings of the prior study (images reviewed) of , the pericardial effusion is slightly larger; still no evidence of frank tamponade, but careful serial clinical and echocardiographic followup is recommended. brief hospital course: 84 year old m with history of lymphoplasmacytic lymphoma/splenic lymphoma s/p 4 weekly doses of rituxan in , and recent -r x2 (c2d1 on ) who is admitted for rituximab desensitization. acute # rituxan desensitization: on recent admission , pt developed hypotension/dyspnea/hypoxemia/fever during infusion of rituximab. he was treated with tylenol, bendaryl, decadron, hydrocortisone. started infusion on the evening of , initially with low concentration then higher concentration. while infusing the 3rd bag, he became tachypneic, tachycardic, hypertensive (150/105)(had gotten benadryl 25mg at 10:30), mildly stridorous and with rigors, gave an additional 25mg benadryl and an albuterol neb. infusion was held overnight. on the following day it was restarted at a slower rate and was well-tolerated. discharged home with family. . #dyspnea: cxr showed a large right sided pleural effusion of unknown etiology. after his initial reaction to the rituxan, he was given lasix for diuresis which improved his saturation and his dyspnea. chronic # lymphoplasmacytic lymphoma: s/p four doses of rituxan , s/p c2 r-bendamustine c/b infusion reaction to rituxan. received a unit of prbcs for anemia. . #seizure prophylaxis -continue home keppra for seizure prophylaxis. # hypertension/chf: has mild shf, recent echo ef 40-45%. in setting of rituximab desensitization, held home lisinopril, metoprolol and resumed on discharge. # bph: -continue home oxybutynin # anemia: continued home iron supplementation. received one unit prbcs. transitional issues # chest xray shows large right pleural effusion of unknown etiology. # echocardiogram shows an increasing pericardial effusion that should be followed regularly. medications on admission: fluoxetine 20 mg capsule sig: two (2) capsule po daily (daily). levetiracetam 500 mg tablet sig: one (1) tablet po bid (2 times a day). omeprazole 20 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po daily (daily). oxybutynin chloride 5 mg tablet sig: one (1) tablet po bid (2 times a day). ferrous sulfate 300 mg (60 mg iron) tablet sig: one (1) tablet po twice a day. metoprolol succinate 50 mg tablet extended release 24 hr sig: one (1) tablet extended release 24 hr po once a day. lisinopril 40 mg tablet sig: one (1) tablet po once a day. furosemide 40 mg tablet (recently increased from 20-> 40mg daily) stopped: allopurinol 100 mg tablet sig: one (1) tablet po once a day. lorazepam 0.5 mg tablet sig: one (1) tablet po hs (at bedtime) as needed for insomnia. potassium chloride 10 meq tablet extended release sig: two (2) tablet extended release po once a day. disp:*60 tablet extended release(s)* refills:*2* discharge medications: 1. fluoxetine 20 mg capsule sig: two (2) capsule po daily (daily). 2. levetiracetam 500 mg tablet sig: one (1) tablet po twice a day. 3. omeprazole 20 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po daily (daily). 4. oxybutynin chloride 5 mg tablet sig: one (1) tablet po bid (2 times a day). 5. ferrous sulfate 325 mg (65 mg iron) tablet sig: one (1) tablet po twice a day. 6. metoprolol succinate 50 mg tablet extended release 24 hr sig: one (1) tablet extended release 24 hr po once a day. 7. lisinopril 40 mg tablet sig: one (1) tablet po once a day. 8. furosemide 40 mg tablet sig: one (1) tablet po once a day. 9. lorazepam 0.5 mg tablet sig: one (1) tablet po at bedtime as needed for insomnia. 10. potassium chloride 10 meq tablet extended release sig: two (2) tablet extended release po once a day. discharge disposition: home with service facility: visiting nurses discharge diagnosis: lymphoplasmacytic lymphoma rituxan sensitivity discharge condition: level of consciousness: alert and interactive. activity status: ambulatory - independent. mental status: confused - sometimes. discharge instructions: mr. , it was a pleasure caring for you at . you were admitted to the hospital for monitoring while receiving rituxan. you initially had a reaction, but then your infusion was slowed and you successfully received the dose of rituxan. weigh yourself every morning, md if weight goes up more than 3 lbs. no medication changes followup instructions: please have your blood counts checked at dr. clinic on monday. please contact his office for followup . procedure: injection or infusion of cancer chemotherapeutic substance immunization for allergy diagnoses: anemia, unspecified congestive heart failure, unspecified hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) hypopotassemia need for desensitization to allergens other and unspecified hyperlipidemia long-term (current) use of other medications antineoplastic and immunosuppressive drugs causing adverse effects in therapeutic use chronic systolic heart failure dementia in conditions classified elsewhere without behavioral disturbance unspecified hereditary and idiopathic peripheral neuropathy tachycardia, unspecified stridor venous (peripheral) insufficiency, unspecified other acquired deformities of ankle and foot unspecified hypertensive heart disease with heart failure tachypnea other named variants of lymphosarcoma and reticulosarcoma, unspecified site, extranodal and solid organ sites other secondary thrombocytopenia personal history of allergy to other specified medicinal agents encounter for antineoplastic chemotherapy other pancytopenia chills (without fever)
