Raiyan Kaldybaye, a 21-month-old from Kazakhstan whose parents are doctors, was born with a congenital enzyme deficiency.
This disease, called Mucopolysaccharidosis type 1, can cause stunted growth, heart failure, and even mental disorders by impeding bone development. It damages many organs, especially the brain, and reduces quality of life. Although a temporary solution was provided with expensive enzyme supplements, Raiyan needed to be saved from this disease with a 100% matching bone marrow transplant.
PARENTS ARE DOCTORS The parents, who are doctors, applied to the Ministry of Health of Kazakhstan. They contacted Yeni Yüzyıl University Gaziosmanpaşa Hospital in Istanbul and requested help for their child's treatment. The family was tested, and the bone marrow of the 7-year-old sister was found to be a 100% match with Raiyan. After an operation performed by Prof. Dr. Barış Malbora, the Head of the Pediatric Bone Marrow Transplant Center at Gaziosmanpaşa Hospital, Raiyan came back to life. In check-ups conducted 73 days later, it was understood that he was cured of the disease. Stating that they encounter such cases from all over the world, Dr. Malbora said, "If her sister hadn't been a match, we would have applied to TÜRKÖK."
