Medication Summary
The overall aim of therapy is treatment of any underlying condition and general suppression of the immune response. Mild anti-inflammatory medications (eg, NSAIDs) are effective in mild cases, and corticosteroid therapy is reserved for the more severe or refractory cases. Patients who require potent immunosuppression or other more aggressive therapies for severe disease should be treated by a specialist. Cyclophosphamide may be used as a steroid-sparing agent or administered concomitantly in severe cases of vasculitis, particularly in patients with renal disease. Azathioprine is commonly used as a steroid-sparing agent, and chlorambucil has also been used for severe vasculitis.
Nonsteroidal anti-inflammatory drugs
Class Summary
NSAIDs such as ibuprofen, naproxen, and indomethacin have analgesic, anti-inflammatory, and antipyretic activities. Their mechanism of action is not known, but they may inhibit cyclooxygenase activity and prostaglandin synthesis. NSAIDs may have additional mechanisms, such as inhibition of leukotriene synthesis, lysosomal enzyme release, lipoxygenase activity, neutrophil aggregation, and various cell membrane functions. NSAIDs are used to reduce the resultant inflammatory response of cryoglobulin precipitation.
Ibuprofen (Advil, Motrin, Excedrin IB, Ibuprin)
NSAIDs are the DOC in patients with mild symptoms of arthralgia or fatigue. Inhibits inflammatory reactions and pain by decreasing prostaglandin synthesis.
Corticosteroids
Class Summary
These medications are used to reduce the resultant immune response from cryoglobulin precipitation, particularly in patients with more severe symptoms or some evidence of organ damage.
Prednisone (Sterapred)
DOC in patients with evidence of acute vasculitis.
Immunosuppressive agents
Class Summary
These are commonly used as steroid-sparing agents.
Cyclophosphamide (Cytoxan, Neosar)
Chemically related to nitrogen mustards. As an alkylating agent, the mechanism of action of the active metabolites may involve cross-linking of DNA, interfering with growth of normal and neoplastic cells.
Azathioprine (Imuran)
Antagonizes purine metabolism and inhibits synthesis of DNA, RNA, and proteins. May decrease proliferation of immune cells, which results in lower autoimmune activity.
Chlorambucil (Leukeran)
Alkylates and cross-links strands of DNA, inhibiting DNA replication and RNA transcription.
Interferons
Class Summary
These agents are naturally produced proteins with antiviral, antitumor, and immunomodulatory actions. IFN-alfa is generally administered subcutaneously.
Interferon alfa-2b (Intron A)
Protein product manufactured by recombinant DNA technology. Mechanism of antitumor activity is not clearly understood; however, direct antiproliferative effects against malignant cells and modulation of host immune response may play important roles. Has antiviral activity in HCV infection.
Peginterferon alfa-2a (Pegasys)
Used in combination with ribavirin to treat patient with chronic HCV infection who have compensated liver disease and have not received IFN-alfa previously. Consists of interferon alfa-2a attached to a 40-kD branched PEG molecule. Predominantly metabolized by the liver.
Peginterferon alfa 2b (PEG-Intron)
Escherichia coli recombinant product. Used to treat chronic HCV infection in patients not previously treated with INF-alfa who have compensated liver disease. Exerts cellular activities by binding to specific membrane receptors on cell surface, which, in turn, may suppress cell proliferation and may enhance phagocytic activity of macrophages. May also increase cytotoxicity of lymphocytes for target cells and inhibit virus replication in virus-infected cells.
Antiviral agents
Class Summary
Nucleoside analogs are initially phosphorylated by viral thymidine kinase to eventually form a nucleoside triphosphate. These molecules inhibit herpes simplex virus (HSV) polymerase with 30-50 times the potency of human alpha-DNA polymerase.
Ribavirin (Virazole)
Antiviral nucleoside analogs. Chemical name is 1-beta-D-ribofuranosyl-1H-1,2,4-triazole-3-carboxamide. Given alone, has little effect on the course of HCV infection. When used with IFN, significantly augments rate of sustained virologic response.
Antiviral Agent, Oral
Class Summary
This agent inhibits the viral reverse transcriptase enzyme, which limits viral replication.
Entecavir (Baraclude)
Guanosine nucleoside analogue with activity against HBV polymerase. Competes with natural substrate deoxyguanosine triphosphate to inhibit HBV polymerase activity (ie, reverse transcriptase). Less effective for lamivudine-refractory HBV infection. Indicated for treatment of chronic hepatitis B infection. Available as tab and oral solution (0.05 mg/mL; 0.5 mg = 10 mL).
Antineoplastic agents
Class Summary
These agents inhibit cell growth and proliferation.
Rituximab (Rituxan)
Genetically engineered human monoclonal antibody directed against the CD20 antigen found on the surface of normal and malignant B lymphocytes.
Immunomodulates response against malignant cells.
