What are autologous stem cell transplants?
Autologous stem cell transplants are typically used in people who need to undergo high doses of chemotherapy and radiation to cure their diseases. These treatments are likely to damage the bone marrow.
What are autologous serum eye drops?
Autologous serum eye drops are a popular treatment for severe dry eye syndrome. 1 Dry eye syndrome is a chronic lack of moisture in the eye. If left untreated, dry eye syndrome may weaken vision and lead to eye infections.
What is the difference between allogeneic and autologous treatments?
In the case of autologous treatments, the donor is oneself. Meaning, the cells are collected from the patient and then re-administered to the same person from which they were sourced. In short, allogeneic means “from another person” while autologous means “from oneself.”
What is the mechanism of action of autologous serum?
The mechanism of action of autologous serum drops is to mimic the biochemical properties of natural basal tears in order to heal the ocular surface epithelium. Barriers to using autologous serum include cost and chair time, but patients tend to have better and quicker improvement compared with use of traditional dry eye drops.
What is an autologous procedure?
A procedure in which a patient's healthy stem cells (blood-forming cells) are collected from the blood or bone marrow before treatment, stored, and then given back to the patient after treatment.
How does autologous cell therapy work?
Autologous treatments available involve taking skeletal muscle from the patient's back or abdomen to be enveloped over the weak heart, and subsequently using a device similar to a pacemaker, to electrically stimulate the transplant.
What is a autologous transplant and how does the treatment work?
In an autologous transplant, your own blood-forming stem cells are collected. You are then treated with high doses of chemotherapy. The high-dose treatment kills the cancer cells, but it also gets rid of the blood-producing cells that are left in your bone marrow.
What is autologous transplant?
An autologous stem cell transplant uses healthy blood stem cells from your own body to replace your diseased or damaged bone marrow. An autologous stem cell transplant is also called an autologous bone marrow transplant.
What is the life expectancy after a stem cell transplant?
The relative mortality rate was high early after transplant as expected (standardized mortality ratio [SMR], 34.3 in the first 2-5 years) but persisted beyond 30 years (SMR, 5.4). Factors estimating mortality included age, high-risk disease, chronic GVHD, and use of PBSC grafts.
Who qualifies for autologous stem cell transplant?
Which patients are candidates for autologous stem cell transplantation? Usually, ASCT is indicated for patients under 65 years of age with no severe comorbidities.
What is the difference between autologous and allogeneic?
Autologous: Auto means self. The stem cells in autologous transplants come from the same person who will get the transplant, so the patient is their own donor. Allogeneic: Allo means other. The stem cells in allogeneic transplants are from a person other than the patient, either a matched related or unrelated donor.
What are the advantages of autologous stem cell transplant?
Faster recovery of cell counts, lesser transplant morbidity, shorter hospital stay and reduced cost compared with marrow autografts have been the main advantages of autologous peripheral blood cell over marrow transplants.
Is autologous stem cell transplant painful?

How successful is autologous stem cell transplant?
The standard treatment for relapsed and primary refractory HL is salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT), which has shown a 5-year progression-free survival rate of ∼50%–60%.
Before the collection procedure
A few days before your collection, a doctor will give you a prescription to increase the number of stem cells your body makes. You’ll take the prescription every day in the days leading up to your autologous cell collection.
During the collection procedure
The actual collection is done by withdrawing blood from your body through a vein, just like you would for a blood draw or blood donation.
After the collection procedure
Typically, collections are done as outpatient procedures. You’ll be able to go home between collections if you need more than one. Most people are able to resume their daily activities after the autologous blood collection.
Before the transplant procedure
Your next step after collection is to receive the high-dose chemotherapy treatment needed to kill the cancer cells in your body. Radiation is sometimes given along with high-dose chemotherapy, but not always.
During the transplant procedure
You’ll receive your stem cells back into your bloodstream by intravenous (IV) infusion. This procedure is the same as a standard blood transfusion.
After the transplant procedure
You’ll likely stay in the hospital for 2 to 3 weeks following your transplant. Doctors will monitor you to:
Recovery period
It can take 2 to 4 weeks before you can return to work or school, and 1 to 3 months before you’re able to fully return to your previous level of activity after an autologous cell transplant.
What is autologous stem cell transplant?
An autologous stem cell transplant uses healthy blood stem cells from your own body to replace your diseased or damaged bone marrow. An autologous stem cell transplant is also called an autologous bone marrow transplant. Using cells from your own body during your stem cell transplant offers some advantages over stem cells from a donor.
Why do people need autologous stem cells?
Autologous stem cell transplants are typically used in people who need to undergo high doses of chemotherapy and radiation to cure their diseases. These treatments are likely to damage the bone marrow. An autologous stem cell transplant helps to replace the damaged bone marrow.
Where do stem cells go after autologous transplant?
Your stem cells will be infused into your bloodstream, where they will travel to your bone marrow and begin creating new blood cells. After your autologous stem cell transplant, you'll remain under close medical care. You'll meet with your care team frequently to watch for side effects and to monitor your body's response to the transplant.
What is the difference between autologous and allogeneic treatment?
What is the difference between an allogeneic and autologous treatment? Whether it is a stem cell treatment, a bone marrow transplant, or another type of cellular therapy, allogeneic means “from another person” while autologous means “from oneself.”
Why are autologous transplants not good?
They also reduce the probability of side effects. One situation in which autologous transplants aren’t a good idea is when the patient has cancer. In this case, the risk of re-transmitting it into the patient through significant.
What is an allogeneic transplant?
An allogeneic transplant is when donor cells are collected from another person who is not the patient. Hematopoietic Stem Cell Transplantation (HSCT) is the most common example of an allogeneic transplant procedure, because it involves the use of stem cells collected from another person’s: HSCT is a widely accepted type ...
Is it better to use donor cells or autologous stem cells?
In this case, donor cells are a better choice. Unless the treatment strategy is a gene therapy, in which a patient’s genes are modified prior to re-administering them, it is also inappropriate to use an autologous stem cell transplant is when the patient has a genetic condition.
How much does autologous serum cost?
Costs for compounding the serum for patients will most likely range from $175 to $300 for a two-month supply .
How long does it take for autologous serum to clot?
Autologous serum eye drops are prepared by drawing the patient’s blood into a sterile tube and allowing the blood to clot for at least 10 hours. The blood is then centrifuged or spun for 15 minutes so the serum is separated. The serum is then diluted in sterile saline and then frozen. 3 .
How to treat dry eye syndrome?
In more severe forms of dry eyes, gels and ointments are prescribed. Steroid eye drops are prescribed in some cases as well as cyclosporine eye drops. 2 Steroids and cyclosporine medications work on the body’s immune system and aim to decrease inflammation and increase tear production. Sometimes physical procedures are also recommended for dry eye treatment. Punctal occlusion, a painless procedure where small collagen or silicone implants are placed into the eye’s puncta or drainage canal, improve the available tears to the eyes and decrease tear drainage away from the eye. In more severe cases, sometimes the puncta are simply cauterized closed. 2 Other conventional treatments sometimes prescribed are vitamin and mineral supplements. Finally, night-sleeping masks and moisture goggles are prescribed to decrease exposure to the air and to decrease the evaporation of the tears.

What will happen before the transplant?
Depending on your disease or condition, you might have chemotherapy to prepare for the transplant weeks or months beforehand. If you have blood cancer, for example, the chemotherapy will get your condition into ‘remission’, which means there is no sign of cancer in your body.
Collecting your stem cells
You will go to hospital to have your own stem cells collected weeks or months before your transplant day. This timing can vary and will depend on your particular situation.
Conditioning therapy
Before your stem cell transplant, your bone marrow and immune system need to be treated and prepared for the new cells. This is done with chemotherapy. You’ll normally start your conditioning therapy the day you go into hospital. It can take one day, 10 days, or sometimes even longer depending on your treatment.
What will happen during the transplant?
Your transplant normally takes place the day after the conditioning therapy has finished. The transplant involves having your previously collected stem cells thawed out and given to you through your PICC line or into your bloodstream. This is a bit like having a blood transfusion. The transplant isn’t painful and you’ll be awake the whole time.
Recovering from an autologous stem cell transplant
You’ll probably be in hospital for about two to three weeks after your transplant and you’ll need to spend some time in protective isolation. You’ll usually be in a single hospital room with precautions taken to protect you from infection. For information about how to cope during this time see our webpage Your Stay in Protective Isolation.
