HLA Matching in Ethiopia – Find Cost, Best Hospitals, and Success

HLA Matching refers to human leukocyte antigen matching. It is a process that compares the HLA types of a donor and a patient to know if both are compatible for treatment like a transplant. HLAs are proteins present on the cell’s surface that help the immune system of the body to know its cells and foreign bodies. HLA matching is an important process for organ transplantation as this significantly increases the success of transplant and longevity. HLA matching is beneficial for adults and pediatric transplants. Recent advances have improved early graft outcomes. Most HLAs help to protect the body from harm, but HLA-B27 is a specific type of protein that may cause immune system dysfunction. The presence of HLA-B27 on the white blood cells can negatively affect the immune system and attack self-functions, organs, and healthy cells, which leads to autoimmune diseases like juvenile rheumatoid arthritis. HLA test is recommended to detect the presence of HLA B27 to detect autoimmune diseases like ankylosing spondylitis, reactive arthritis, Juvenile rheumatoid arthritis, and anterior uveitis.

Does HLA Matching get Insurance Coverage in Ethiopia?

Medical insurance in Ethiopia is not available for everyone; only 28% of the population gets insurance coverage. The general insurance coverage in Ethiopia varies by region. Rural residents are more likely to get more benefits than urban people. People with a high wealth index and large families are also entitled to be insured. However, HLA matching is a part of transplant treatments; it may come under transplant insurance policy. The patient is required to find out if their treatment is eligible for insurance during consultation.

What are the Categories of HLA Matching?

HLA matching has different categories based on the amount of HLA matching between donor and recipient for organ or stem cell transplantation. Every person has two unique sets of HLA genes which are inherited from each patient and the numbers indicate how many of those are identical between the recipient and donor. Here are the important HLA matching numbers:

10 10 HLA Match indicates perfect match

12 12 HLA Match are broader range of matching for desirable transplantation

5 10 HLA Match indicates donor and recipient have five matching HLA alleles out of ten tests. It is a moderate match.

6 6 HLA Match indicates 6 specific HLA loci and is especially required for bone marrow transplant. It is a good number but not as good as higher numbers.

7 10 HLA Match indicates that the recipient and donor have seven alleles out of 10 tested. It’s a favorable match but has chances of risk and complications.

Who Is a Suitable Candidate For HLA Matching

• A person needing an organ transplant like a kidney, liver, or heart to lower the risk of organ rejection
• A patient needs a bone marrow transplant due to blood disorders like lymphoma, leukemia, or aplastic anemia.
• Patients with genetic disorders
• Patients with autoimmune diseases

Who is not a Suitable Candidate for HLA Matching

• People with diseases and infections
• People who had recent cancer treatment
• People with poor health
• People with active autoimmune diseases

HLA Matching Success Rate in Ethiopia

Ethiopia’s best hospitals offer the latest HLA-matching procedures and treatments. The general HLA match rate for the Ethiopian population is 12% because it depends on the genetic diversity of the patient and donor. HLA matches can be obtained from family members like siblings, parents, twins, or unrelated donors. The success rate of HLA match with 10/10 from donors is 65% – 85%. The HLA match with siblings who share the same parent has 25% of the complete match.

Comprehensive Guide to HLA Matching Across Various Transplant Types

HLA Matching Kidney Transplant

HLA matching for kidney transplants is an essential factor to reduce the chances of rejection and graft loss. Getting a closer match can increase the longevity of quality of life. For example, a kidney with 12 12 HLA matches has a higher chance of lasting 20 years or more. However, it’s important to keep in mind there are more chances of rejection if the donor is an older, mismatched donor, highly sensitized patients who have longer waiting times.

HLA Bone Marrow Transplant

HLA matching is important for successful bone marrow transplants. Getting an exact match HLA from a family member increases the chances of a successful transplant and cells grow with less risk of complications. A fully HLA-matched sibling shown high-resolution typing of HLA-A, B, and -DRB1, is the best donor choice for allogeneic hematopoietic cell transplantation ensuring a 6/6 match for the successful outcome. For partially HLA mismatched related donors, including that patient with one antigen mismatch or haploidentical relatives can offer viable graft options with less requirement of a 7/8 match or a ≥ 4/8 match at HLA-A, -B, -C, and -DRB1, respectively, while careful screening for specific screening of antibodies is important to reduce graft failure risks.

HLA Epitope Matching

It is a method that helps to predict the compatibility of a donor and recipient based on the HLA antigens of the recipient and donor. If the donor and recipient have an HLA epitope, the recipient body will not detect it as a foreign body and will not trigger an immune response. HLA epitope matching helps to detect differences in amino acid sequence, physicochemical properties, and structural properties of HLA alleles. There are also chances of unexpected antibody reactivity.

HLA Matching For Stem Cell Transplant

HLA matching is required for a blood stem cell transplant with the matching donor. Different HLA genes are linked with immune conditions like ankylosing spondylitis and coeliac disease; therefore, HLA typing is used to help diagnose these conditions. Stem cell transplants with HLA have reduced GVHD (Graft-versus-host disease) and enhanced Engraftment of stem cells to produce new blood cells. HLA matching for stem cell transplants is used for sibling, unrelated, and cord blood donors.

HLA Matching With Parents

HLA matching with parents is considered when a child has at least one haplotype with both parents. It is a rare condition, and some families have close relative marriage. Parent and child have a 50% match in both parents making it a 100% match for a child to get successful treatment.

Hla Platelet Matching

HLA platelet matching allows the treatment of patients with stubborn to rare platelet transfusions, which means they do not respond well to transfusion from mismatched donors. It happens because of HLA alloimmunization when a patient develops HLA antibodies. The HLA platelet matching is also used for patients undergoing stem cell transplantation from half-matched donors. HLA platelets are graded in different degrees of match. For example, grade A has a 4/4 antigen, considered a perfect match.

Where to get HLA Tested?

You can get HLA testing at transplant centers or cancer clinics. HLA testing should be performed after diagnosis.

How to Prepare for the HLA Match?

• There is no special preparation for the HLA matching test. This test only requires a blood sample or cheek swab. However, follow the below steps:
• Get consultation and discuss the need for an HLA match.
• Know your HLA typing for transplants or medical decisions.
• Find out a testing facility or get a recommendation from doctors.
• Follow your doctor’s guidance for pre-test and after-test for food intake and prevention. Every patient may have different requirements.
• Know your family member as an HLA match.
• Emotionally prepare yourself for medical decisions.

Advanced Technology for HLA Matching

The growing world has introduced several advancements for HLA Matching to ensure patients can get standard practice with the best compatibility between recipients and donors to prevent rejection by the immune system. Here are the key advancements in HLA Matching:

Next-generation sequencing is the best DNA sequencing technology and a good option for high-resolution typing of HLA genes, finding polymorphisms that are not easily detectable in traditional methods. It also delivers a comprehensive analysis of multiple HLA loci and enhances matching accuracy. This is a cost-effective option for sequencing large gene sets. It is user-friendly and helpful for tracking infectious diseases.

Single-Nucleotide Polymorphism (SNP) Typing SNPs are a common type of genetic variation among people. Every SNP provides the difference in a single DNA building block called a nucleotide. SNP may change the nucleotide cytosine with the nucleotide in a stretch of DNA. Most SNP are present in DNA between genes and act as biological markers which helps scientists to detect the disease.

Bioinformatics Tools are available in various forms, such as HLAreporter, Easy-HLA, SOAPTyping, HLA analyzer, and Hapl-o-Mat. These tools work with software and algorithms to analyze genetic data for HLA matching to predict donor and recipient compatibility.

HapLogic is another advancement in HLA matching. It is a predictive human leukocyte antigen matching algorithm. It helps improve the rapid identification of the optimal unrelated hematopoietic stem cell sources for transplantation. This innovation was developed by the National Marrow Donor Program as a search algorithm. This algorithm provides high predictive accuracy to optimize nonrelated donor and umbilical cord blood selection and improve efficiency in the search process of stem cell transplantation.

Waiting Time for HLA Matching

Patients are required to wait for HLA matching before getting a transplant. The waiting time varies based on different factors, like the availability of donors and patient requirements. Different organs need different wait times, like kidney transplants and liver transplants, so the list of waiting patients may take time. The location of the patient and hospital also adds up to waiting time as the patient may need to travel to different places for a transplant due to limited medical facilities in their area. If the patient finds a match with a family member, the waiting time may be reduced, but the case of finding a donor out of the family may again increase the waiting period. There might be chances of getting a deceased or living donor, and then all tests required to be made impact waiting times.
