Which condition is associated with Hepatitis C and cryoglobulinemia according to the sources?

• A. Cryoglobulinemic GN
• B. IgA nephropathy
• C. Minimal change disease
• D. FSGS

Answer: (A)

Hepatitis C frequently drives mixed cryoglobulinemia, where circulating cryoglobulins form immune complexes that deposit in the glomeruli and trigger inflammation. In the kidney this leads to cryoglobulinemic glomerulonephritis, often with a membranoproliferative GN pattern, low complements (especially C4), and immune deposits of IgM with rheumatoid factor activity along with IgG and C3. The other options don’t fit this link: IgA nephropathy involves IgA deposition in the mesangium; minimal change disease causes nephrotic syndrome with normal light microscopy; FSGS reflects podocyte injury and sclerosis. Thus the condition associated with Hepatitis C and cryoglobulinemia is cryoglobulinemic glomerulonephritis.
