Globally, only half of the Women get treatment for the Rh disease and may be linked to the deaths of more than 1,00,000 foetuses and newborns worldwide*

NAIROBI, Kenya, Dec. 11, 2024 /PRNewswire/ -- The Rh factor (Rhesus factor) is a red blood cell surface antigen also known as Rh disease, is a condition that occurs when a woman with Rh-negative blood type is exposed to Rh-positive blood cells, leading to the development of Rh antibodies. Rh incompatibility can occur in 2 ways. The most common type occurs when a Rh-negative pregnant mother is exposed to Rh-positive fetal red blood cells secondary to fetomaternal haemorrhage during pregnancy from spontaneous or induced abortion, trauma, invasive obstetric procedures, or normal delivery.

A treatment developed over 50 years ago to prevent Rh disease—an often-fatal condition in foetuses and newborns—only reaches half of the women in the world who need it, according to a study led by researchers at Vagelos College of Physicians and Surgeons (VP&S) at Columbia University Irving Medical Centre*. Leading doctors appreciated the impact and effectiveness of this treatment but are concerned about its access and reach.

"This treatment is the standard of care for preventing Rh disease, but we recognize that there remain significant obstacles to expanding access to this lifesaving therapy around the world," says Spitalnik, who has been working with an international team of physicians to increase access to therapy with Rh(D) immunoglobulin around the world. *

Improved access which currently is a challenge, could change the outcomes dramatically, saving lives. Hence there is an utmost need to highlight the role of antenatal care and its crucial role in prevention of Rh diseases across African region.

So, what is the problem and Role of Antenatal care and Collaborative strategies from KOGS and govt institution/insurance organisation for supporting Rh disease prevention in Kenya?

"According to our research in Kenya, the prevalence of Rhesus negativity among pregnant women is significantly higher than previously believed and varies by county. The range is between 6-10%, inconsistent with prior reports that claimed an average of 4%. This suggests that the need for treatment is likely to increase and the government must put policies in place to meet this demand" said Dr. Moses Obimbo, a Professor at the University of Nairobi and KOGS Hon Secretary.

According to KOGS, Rhesus isoimmunization : an underappreciated reproductive risk, article published in JOGECA 2023, there has been a contentious suggestion for the universal prophylactic use of anti-D immunoglobulin in all pregnancies, including those following termination or ectopic pregnancies. Despite being preventable, Rhesus disease was identified as one of the roadblocks to achieving maternal universal health coverage. The team recommended all stakeholders to facilitate access to anti-D immunoglobulin and screening tools for widespread screening and treatment.^

Such measures would go a long way in prevention of Rh disease. The first step in creating awareness though is also the simple knowledge of one's own blood groups and Rh testing.

Knowing your Rh status reduces these risks dramatically

Rh sensitization is evaluated by a blood test known as indirect Coombs' test. This test can assess presence of cell-destroying antibodies and alert the doctor to take appropriate treatment. Effects of Rh incompatibility can be prevented by getting an injection of RhIg (Rh immunoglobulin,) during the first course of pregnancy, abortion, miscarriage, while having any bleeding during pregnancy or within 72 hours of delivery.

Importance of Blood group testing in pregnant women

"Uganda has made significant strides in the reduction of maternal mortality from haemorrhage and hypertensive disorders of pregnancy. However, we should not forget the morbidity and suffering caused by Rhesus incompatibilities during all trimesters of pregnancy and after childbirth. Make Blood group/Rhesus testing an indicator of quality of care at all levels offering care to women" said Dr. Othiniel Musana, Member Senior Leader Team National Safe Motherhood Expert Committee (NASMEC), President of Association of Obstetricians and Gynaecologists of Uganda (AOGU) 2021-2023.

How is Rh incompatibility managed?

If a Rh-negative woman is pregnant and has given birth to a Rh-positive child in the past, the doctor can test for Rh positive antibodies in her blood, and even take a sample of amniotic fluid to check for bilirubin levels in the fetus (amniocentesis). It is possible to take a sample of fetal blood from the umbilical cord as well.

Once diagnosed, depending on the severity of the disease, the fetus may either require single or multiple intrauterine blood transfusions or it may have to be delivered early to manage complications.

Haemolytic disease of the newborn is a devastating disease for babies and their families and is a huge challenge to handle. But it does not have to be. Being forewarned is being forearmed and awareness of this condition can go a long way in saving lives

Collaborative strategies from AGOTA with govt institution/insurance organisation for supporting Rh disease prevention.

"The association of Gynaecologists and Obstetricians of Tanzania (AGOTA) has worked very closely with the Government and other health concerned stakeholders like BSV in preparing guidelines, mentoring and evaluating of all issues pertaining to maternal newborn and child health including Rh incompatibility. The awareness of antenatal care in Tanzania is of paramount with the aim of solving the existing challenges of provision of antenatal care services focusing on improving maternal and perinatal outcome. The Government of Tanzania priority is to insure universal, quality, comprehensive and equitable health services to all of its citizens, with much emphasis on improving health status of women and children" said Dr. Matilda Ngarina - AGOTA President.
