- low blood counts
- electrolyte imbalances
- organ function
- symptoms of cytokine release syndrome or ICANS
Complications can develop during this time that may be severe or even life-threatening. It may be necessary to admit you to the hospital to treat these problems.
- temporary memory problems
- coordination problems.
Your family caregiver will need to transport you to and from the clinic for check-ups.
Approximately four weeks after CAR T-cell therapy, tests will be done to assess how well the treatment is working. These tests may include
- a PET/CT scan
- a bone marrow biopsy
- additional lab tests, depending on your disease
If all is well, the clinic visits will end and you can return home.
Recovering from CAR T-cell therapy can take several weeks or months. While your body recovers:
- you will feel very tired and weak
- you may not have much of an appetite
In some cases, low blood counts can persist for many months. This can increase your risk of developing an infection. It is common for patients to be on antimicrobial medications for several months after CAR T-cell therapy.
Until your immune system recovers you should take precautions to reduce your risk of developing an infection. Your medical team will give you specific guidelines. The most important of these is frequent, thorough hand-washing with soap and water before:
- eating or preparing food
- taking medications
Be sure to wash your hands after:
- touching catheters and wounds
- changing diapers (if you are permitted to do so)
- touching plants or dirt (if you are permitted to do so)
- going to the restroom
- touching animals
- touching bodily fluids or items that might have come in contact with bodily fluids such as clothing, bedding or toilets
- going outdoors or to a public place
- removing gloves
- collecting or depositing garbage
To reduce your risk of developing an infection, your medical team may recommend that you avoid:
- people who have, or have been exposed to, an infection
- gardening or digging in dirt
- smoking or being around people who smoke cigarettes, cigars, e-cigarettes, a pipe or marijuana
- walking, wading, swimming or playing in ponds or lakes
- construction sites and remodeling projects
Cleaning kitchen counters and bathrooms daily with a solution of one part bleach to 10 parts water can help eliminate sources of infection.
Ask your care team about getting the flu, shingles and COVID vaccinations and whether your should take Evusheld™ to reduce the risk of getting COVID.
After CAR T-cell therapy, some patients experience neurological problems for several weeks or months. Problems may include:
- difficulty remembering things
- poor concentration
- difficulty finding the right word
- difficulty planning and staying organized
Often it’s the caregiver, rather than the patient, who first notices these behavioral changes in the patient. It helps if the caregiver writes down when the problems start and end, so that accurate information can be shared with the medical team.
Report Problems Promptly
If you develop new symptoms or have questions, be sure to reach out to your CAR T-cell therapy team right away for help. Problems are usually easier to treat when they are caught early.
