Found an article from the New England Journal of medicine NEJM first hit in my google search
“Membranoproliferative Glomerulonephritis Associated with Hepatitis C Virus Infection“
Apparently this condition is on the spectrum of known extrahepatic conditions that are associated with hep c infection in some patients.
There is an article titled “Extrahepatic manifestations of chronic hepatitis C virus infection” on ncbi.nlm.nih.gov you can read on the subject of extrahepatic conditions associated with hep c.
Again first hit on google when I searched extrahepatic and hep c
I trust you are discussing your condition with your gastroenterologist, hepatologist or nephrologist.
