HCV and Rheumatic Disease

Overview

Hepatitis C virus (HCV) infection keeps the immune system continuously switched on, and that ongoing activation can trigger a range of rheumatic problems, including joint pain and swelling, muscle aches, inflamed blood vessels, and cryoglobulinemia, a buildup of abnormal proteins that can clump together in cold temperatures and affect the kidneys. Some people have few or no symptoms from the virus itself and don't realize they're infected until joint or muscle symptoms bring them to a doctor, sometimes before HCV is ever diagnosed. Because a rheumatic complication can be the first clue to an HCV infection, and because some rheumatic medications can affect the liver, the two conditions are usually best managed together.

Questions to Ask Your Doctor

• Could my joint or muscle symptoms be connected to hepatitis C, and should I be tested for the virus?
• Now that hepatitis C is confirmed, will treating the virus with antiviral medication also improve my joint and muscle symptoms?
• Which of my symptoms are linked to cryoglobulinemia, and does that put my kidneys at risk?
• Are the medications you're considering for my joint pain safe for my liver, given the hepatitis C?
• Should my rheumatology care be coordinated with a liver specialist, and how often should we communicate?

Getting Care

A rheumatologist can evaluate joint, muscle, and blood vessel symptoms linked to HCV, usually alongside a hepatologist, or liver specialist, who manages the virus itself and screens for liver damage. Seek care sooner if you notice new swelling in your legs, blood in your urine, or numbness and pain in your hands or feet, since these can point to kidney or nerve involvement that needs prompt attention.
