Abstract

Objective: Preimpklntation genetic diagnosis (PGD) in combination with preimplantation human leucocyte antigen (HLA) matching lias recently emer¬ged as an effective therapeutic tool for the existing affected sibling: This article summarizes and discusses the clinical outcome of 15 patients undergoing a total of 17 PGD cycles combined with HLA typing (PGD+HLA) for p-Thallasemia (n=14), Acute Lymphoblastic Leukemia, (n=2) and Wiscott Aldrich Syndrome (n=1). Institution: Istanbul Memorial Hospital, ART, Reproductive Endocrinology &Genetics Centre, Istanbul. Material and Methods: In seventeen controlled ovarian hyperstimulation cycles (COH), a total of 149 cleavage stage embryos were biopsied and screened by multiplex amplification followed by computer-assisted analysis. According to results, embryo transfers were performed with the disease-free and/or HLA compatible embryos. Results were evaluated and the effect of clinical parameters on the outcome is discussed. Results: Transfer of 16 suitable (disease-free and/or HLA-compatible) embryos led to 3 viable ongoing pregnancies in 11 embryo transfer cycles (PR/ET,27.3%). However, six cycles (35.2%) were cancelled due to the lack of unaffected, and/or HLA matched embryos. Conclusions: Preliminary data implies that the probability of finding both disease free and HLA compatible embryo is negatively correlated by the number of embryos available for the analysis. Since in most cases these couples are fertile, this variable is primarily determined by a patient's ovarian reserve as well as the selection of an optimum hyperstimulation protocol. on the other hand , although they are only limited number of cases, once suitable blastocyst-stage embryos are available for transfer, they may result in acceptable clinical pregnancies. Therefore, couples seeking this treatment option should be informed in detail about such limitations before a PGD and preimplantation HLA typing procedure is sought.

Özet

Amaç: Preimplantasyon Genetik Tanı (PGT) yöntemi ile kombine HLA doku tiplemesi yöntemi yaşamı tehtid eden genetik hastalığa sahip çocuklar için etkin bir tedavi yöntemidir. Bu şekilde yaşamı tehtid eden talasemi major gibi önemli hematolojik bozukluklarda kordon kanı ve/veya kemik iliği transplantasyonu ile tam olarak kür sağlanabilmektedir. Bu makalede 17 PGT siklusu uygulanan 15 hastanın b talesemi (n=14), Akut Lenfoblastik Lösemi (n=2) ve Wiskott Aldrich Sendromu (n=1) nedeni ile uygulanan PGT ve HLA (PGT-HLA) doku tiplemesi sonuçları tartışılmıştır. Çalışmanın Yapıldığı Yer: İstanbul Memorial Hastanesi, ART, Reprodüktif Endokrinoloji ve Genetik Merkezi, İstanbulMateryal ve Metod: 17 kontrollü over hiperstimülasyonu siklusunda (KOH) toplam 149 embriyoda biopsi işlemi uygulanmış ve multipleks PCR amplifikasyonunu takiben dizi analizi incelemesi yapılmıştır. Sonuçlar doğrultusunda hastalık taşımayan ve/veya HLA uyumlu embriyolar transfer edilmiş, klinik parametrelerin sonuçlara etkisi tartışılmıştır. Bulgular: 16 adet mutasyon taşımayan ve/veya HLA genotiplemesi uyumlu embriyo ile gerçekleştirilen 11 embriyo transferi siklusunda 3 klinik gebelik elde edilmiştir (%27,3). Altı (%35,2) siklus hastalıksız ve/veya HLA uyumlu embriyoların olmaması nedeni ile iptal edilmiştir. Sonuçlar:Ön çalışmalar elde edilen oosit sayısı ile hastalık taşımayan/HLA uyumlu embriyo sayısı arasında negatif korelasyon bulunduğunu göstermektedir. Birçok vakada çiftler fertil olduğundan bu değişken hastanın over rezervi ile seçilecek en uygun over stimülasyonuna bağlıdır. Diğer yandan, her ne kadar vaka sayısı kısıtlı olsa da, transfere uygun blastosist aşamasındaki embriyolar kullanılarak gerçekleştirilen embriyo transferi sonrası kabul edilebilir düzeyde klinik gebelik oranları elde edilebilmektedir. Bu nedenle PGT ve preimplantasyon HLA tipleme protokolüne alınacak hastalar detaylı olarak yöntemin kısıtlamaları ile ilgili bilgilendirilmelidir.
