Passive Immunotherapy

Health Care Term

Passive immunotherapy is a treatment approach that involves the administration of pre-formed antibodies or specific immune cells to a patient with an existing illness or infection. This approach is designed to enhance the immune response and provide immediate protection against a pathogen while the patient*s own immune system mounts a response.

Passive immunotherapy is used extensively in the health care industry for the treatment of a variety of infectious diseases, including viral infections such as hepatitis B, HIV, influenza, and respiratory syncytial virus (RSV), as well as bacterial infections such as tetanus, diphtheria, and anthrax. The approach is also used in the treatment of certain types of cancer, such as lymphoma and leukemia.

One of the most common types of passive immunotherapy involves the use of monoclonal antibodies (mAbs). These are laboratory-generated antibodies that are designed to target specific antigens or proteins found on the surface of cancer cells or infectious agents. Once administered, the mAbs bind to these targets and trigger an immune response that leads to the destruction of the pathogen or cancer cell.

Passive immunotherapy is generally well-tolerated, with few side effects. However, as with any medical treatment, there may be some risks associated with its use, such as allergic reactions, the development of resistance, and the potential for the transmission of infectious agents.

Overall, passive immunotherapy represents an important treatment option for patients with infectious diseases and certain types of cancer. By providing immediate protection and enhancing the immune response, this approach can help to improve outcomes and save lives in a wide range of clinical settings.
