Study Notes
Immune Stimulants
- Interferons are used to treat Hepatitis B and C.
- Interferons modulate the immune response and stimulate interferon receptor sites on non-infected cells.
- Interferons stimulate the production of antiviral proteins that prevent viruses from entering cells.
- Side effects include flu-like symptoms, bone marrow suppression, cardiotoxicity, dyspnea, alopecia, and gastrointestinal upset.
- Monitor complete blood count (CBC) levels, cardiac function, and liver function throughout therapy.
Antiviral Agents
- Antiretroviral protease inhibitors are used to treat Hepatitis C.
- These protease inhibitors block protease activity, rendering the HIV particle incapable of fusing with a cell and injecting itself into a cell.
- Side effects: gastrointestinal effects, changes in liver function, elevated cholesterol and triglyceride levels, fat redistribution, Stevens-Johnson syndrome.
Antiviral Drugs
- Antiviral drugs are used to treat Hepatitis C.
- These drugs inhibit viral DNA replication by competing with viral substrates to form shorter, non-effective DNA chains.
- Side effects include nausea, vomiting, headache, depression, paresthesia, neuropathy, rash, hair loss, and renal dysfunction.
Supplements
- Thiamine is a vitamin used to treat deficiencies.
- Thiamine is required for carbohydrate metabolism.
- Replaces thiamine if dietary deficiencies exist.
- Side effects and reactions are extremely rare.
Immune Stimulants
- Interferons are proteins that modify the immune response by stimulating interferon receptor sites on cells, leading to the production of antiviral proteins that prevent viruses from entering cells.
- Interferons are used to treat Hepatitis B and C.
- Common adverse effects include flu-like symptoms, bone marrow suppression, cardiotoxicity, dyspnea, alopecia, and gastrointestinal upset.
- Monitoring complete blood count (CBC) levels, cardiac function, and liver function throughout therapy is crucial.
Antiviral Agents
-
Antiretroviral protease inhibitors are used to treat Hepatitis C.
-
These drugs block protease activity, preventing HIV particles from fusing with and injecting themselves into cells.
-
Protease inhibitors can cause gastrointestinal effects, liver function changes, elevated cholesterol and triglyceride levels, fat redistribution, and Stevens-Johnson syndrome.
-
Antiviral drugs like Ribavirin (Copegus) are also used to treat Hepatitis C.
-
Ribavirin inhibits viral DNA replication by competing with viral substrates to form shorter, noneffective DNA chains.
-
Common side effects include nausea, vomiting, headache, depression, paresthesia, neuropathy, rash, hair loss, and renal dysfunction.
Supplements
- Thiamine is a vitamin used to treat deficiencies.
- It's essential for carbohydrate metabolism and is given to patients with deficiencies.
- Thiamine has minimal adverse effects.
