A 35-year-old Hispanic female presents to the clinic with fever, fatigue, nausea, and vomiting. Her physical exam is pertinent for both hypertension and edema, and her urinalysis reveals hematuria with red cell casts as well as proteinuria. She confirms that two weeks ago she had an influenza-like illness, but indicates that she took no medications, prescribed or over the counter. You order additional labs, including a test for anti-GBM, which is positive. You tell the patient that the best treatment for her disease is plasmapheresis: the removal of plasma, treatment of it to remove antibodies, and return of it to her circulation. Which of the below is the most likely diagnosis?

A. Acute proliferative GN

B. IgA nephropathy

C. Tubulointerstitial disease

D. RPGN
