The best answer is 3) Membranoproliferative glomerulonephritis (MPGN).
Why:
- The stem gives a nephritic-nephrotic mix: hypertension, edema, microscopic hematuria, and proteinuria.
- It also gives low complement, which strongly supports MPGN pattern disease.
- Hepatitis C positivity is classically linked to cryoglobulinemic GN with an MPGN pattern.
From Harrison’s: HCV-related renal disease often presents with cryoglobulinemia, microscopic hematuria, depressed complement, and commonly includes MPGN lesions (Harrison’s, p. 8620).
Also, MPGN commonly presents with proteinuria, hypertension, hematuria, and hypocomplementemia (Management of Glomerular Diseases, p. 187).
Also, MPGN commonly presents with proteinuria, hypertension, hematuria, and hypocomplementemia (Management of Glomerular Diseases, p. 187).
Exam-wise, when the option is a pathology diagnosis, this constellation points most directly to MPGN.
(If they asked for the associated systemic condition, then mixed cryoglobulinemia would be the linked entity.)
