Potential Side Effects from Immunotherapy for Kaposi Sarcoma
The immunotherapy drug interferon can cause any of these side effects:
Flulike symptoms, such as tiredness, muscle aches, runny nose, or low-grade fever
Abnormal liver enzymes
Mood changes or depression
Low blood cell counts
Immunotherapy drugs can be highly toxic in people with CD4 counts (measurement of CD4 lymphocytes) less than 200. Therefore, highly active antiretroviral therapy that decreases HIV viral load and increases CD4 cell counts is an essential companion of immunotherapy for Kaposi sarcoma.
