Patient received the first Moderna Covid-19 vaccine and a few weeks later he noticed jaundice and hematuria. He was admitted to the Hospital, and was noted to have dramatically elevated eosinophils (26.29 k/uL), elevated creatinine (2.36 mg/dL) and elevated LFTs (AST/AST/Alk Phos/Tbili all up, mostly direct). His eosinophils improved with pulse dose steroids and the diagnostic work up continues. There is diagnostic uncertainty about what caused this dramatic increase in eosinophilia, but it appears temporally related to getting the vaccination. Our working diagnosis is autoimmune vasculitis, but he is also being treated for possible parasitic infection, and will require very close follow-up. 61M with PMHx HTN p/w generalized fatigue, L flank pain, and decreased UOP.   He was in his usual state of health until 5 days prior to admission with onset of general fatigue/sluggishness. This was followed by a few days of dull abdominal pain, watery bowel movements, and increased frequency which spontaneously resolved, though the fatigue persisted. Yesterday evening, he noticed new L flank pain, red urine, and decreased UOP associated with mild dysuria (he describes it as needle-like pain in his urethra) which prompted him to call EMS. Denies fevers/chills/night sweats, myalgias, respiratory symptoms, melena/hematochezia. He's never had pyelonephritis or kidney stones before, no recent urinary instrumentation, antibiotic use, or hospital stays.    He recently received the first COVID vaccine and is due for the second COVID shot on Monday. He lives with his sister and works as a mechanic. He is not on any other medications or supplements. Not currently sexually active.

Notably has been afebrile and fairly well appearing. Symptoms were preceded by several days of watery diarrhea, cough with sputum production and subjective weight loss. Recently received moderna vaccine, and he was concerned it causes his symptoms.  Underwent extensive workup as below with involvement of multiple services including Renal, Pulm, Rheum, Allergy, ENT, and Cardiology. Had one nasal lesion biopsied by ENT, which was non-diagnostic. Renal bx prelim without clear e/o vaculitis, although obtained after steroids. Negative testing for primary hypereosinophilic syndrome. Extensive w/u notable for ANCA positive at 1:80 with  MPO only slightly elevated (20, uln 19) and PR3 wnl.  cMRI with eosinophilic cardiomyopathy, for which cards was consulted as below. Additionally, toxacara ab positive and schistosoma ab indeterminate, although per ID both schistosomiasis and toxacara infection unlikely. Per rheum, overall felt presentation 2/2 hypereosinophilic syndrome, potentially the eosinophilic stage of EGPA (given low + ANCA, low + MPO) vs.  End organ effects of idiopathic eosinophilia. Briefly received CTX 2g IV qd (4/10 - 4/12) until diagnostics returned. Treated with solumedrol 1g qd x3d (4/11-4/13) transitioned to prednisone 60 mg qd (4/14-) to be continued until rheum f/u, with rapid decline in eosinophilia. Received pre-treatment with PO ivermectin 20 mg before steroids. Treated with flonase nasal spray, symbicort and albuterol for respiratory symptoms. Deferred cyclophosphamide, with consideration of IL-5 or IL-5R targeted biologics as an outpatient. Treated with atovaquone for PCP ppx. Per ID, treated with praziquantel (for schistosomiasis) and albendazole (for toxacara) out of an abundance of caution, although low c/f visceral larva migrans given lack of compatible imaging findings and no known exposure to dogs and cats or schistosomiasis given remove travel history.

Baseline Cr unknown but Cr was 1.5 (OSH BI) and urine alb:Cr was elevated to 36 in 6/2018, at which time CKD was thought to be 2/2 untreated HTN. Now presented with persistent hematuria, HTN and proteinuria with UCx without e/o infection, all favoring nephritic process. Renal and urology consulted MALB/CCR 994.5. CT scan with hydronephrosis, felt to be eosinophilic pyelonephritis. Pt underwent uncomplicated renal bx 4/14 (after steroids) which showed preliminary very mild focus of interstitial nephritis with scattered eosinophils and immunofluorescence evidence suggestive of a mild immune complex-mediated disease without current activity. EM pending. He was treated with sodium bicarb 1300 mg bid. Hematuria improved but did not resolved by time of discharge. Cr on discharge 1.6, close to baseline of 1.5 in 2018.    #Sclera Icterus #CBD Dilation on CT #Elevated LFT Sclera icteric and CBD dilation on RUQUS to 1.8cm with gallbladder sludge and small gallstones. MRCP with diffuse intrahepatic and extrahepatic biliary ductal dilatation to the level of ampulla, with associated ductal and gallbladder wall edema, complex material in the gallbladder lumen and CBD, and confluent periportal lymphadenopathy. No obstructing stone or discrete mass. Findings likely represent cholangitis such as eosinophilic cholangitis in light of severe eosinophilia.. No documented LFTs here, but OSH (BI) records indicate normal LFTs and viral hepatitis studies in 6/2018. Repeat Hep B non-reactive non immune, HCV non immune, HAV non-reactive.  BIli remained stable and ALT and AST continued to rise after initiation of steroids. GI was consulted. RUQUS 4/15 with dopplers with persistently dilated CBD to 1.4 cm with sludge in CBD but with patent portal vein and hepatic veins. Anti smooth muscle ab positive on day of discharge; antimitochondrial ab pending. LFT uptrending at time of discharge, although patient declined to stay inpatient for further workup. LFT at discharge ALT 194, AST 114, ALP 262, TBili 6.3, DBili 5.3. ERCP to be considered as an outpatient.     #HTN SBP on admission 160-180. History of HTN, not on any home anti-hypertensives. Per BI records, he was prescribed amlodipine 10/valsartan 160 in 6/2019, but pt reports self-discontinuation after ~2 doses. BP remains poorly controlled. Likely related to potential nephritic syndrome or renal infiltration by eosinophils, likely with contribution of high dose steroids. While inpatient, treated with hydralazine, labetalol, carvedilol, and amlodipine. BP regimen on discharge amlodipine 10 mg qd, carvedilol 25 mg qd. Avoiding ARBs and ACEI per Renal, although will likely need to add once AKI resolved.    #Microcytic Anemia Patient with drop in Hct from 14.1 on admission to 11.4 4/14. Continues with hematuria, but denies current hematochezia. Suspect combination of blood loss and hypopoliferation given RPI 0.29, likely anemia of inflammation/acute illness given ferritin 1.010. Vitamin B12 >2000, Folate 11. Iron 151, unable to calculate TIBC. Noted to have persistently low MCV in low 70. Hemoglobin electrophoresis ordered.    #Vitamin D deficiency #HyperPTH 25-OH Vitamin D 6. No e/o hypocalcemia. Phos slightly elevated on admission, but subsequently downtrending, likely iso renal dysfunction. Treated with ergocalciferol 50,000 U weekly x12 weeks   #Right mandible lesion Sclerotic changes of the right mandible near the condyle noted on CT scan. Surgeon recommends outpatient follow-up, although patient declined.    #Hematochezia #Hemorrhoids Patient with new bloody diarrhea 4/11. Some e/o hemorrhoids on exam. CBC stable. Treated with tucks pads, dibucaine ointment and hydrocortisone cream.   #Little Medical Follow-up Pt reports that he has not seen a doctor in ~3 years.Cholesterol 124l LDL 73, HDL 10. HgbA1c 5.2. Will join Dr's panel on discharge   #CHIP mutation  RHP with DNMT3A mutation at low VAF. Will follow in cancer precursor clinic
