Down Sendromu ve Trombositopeni

Öz

Down sendromu, birçok doğumsal anomalilerle birlikte hematolojik bozuklukların eşlik edebildiği genetik bir has- talıktır. Lösemi benzeri geçici proliferatif bozukluk, lösemi insidansında artış, izole trombositopeni ve trombositoz gibi değişik hematolojik bozukluklar Down sendromunda sıklık- la gözlenmektedir. Down sendromunda görülen trombosi- topeninin etiyolojisi tam olarak bilinmemekte ve bu konu ile ilgili sınırlı sayıda veri bulunmaktadır. Bu makalede Down sendromu kliniğinin trombositopeni ve diğer hema- tolojik parametreler üzerine etkisinin değerlendirilerek, Down sendromu ve trombositopeni yaklaşımında gerekli bilgilerin vurgulanması amaçlanmıştır

Down Syndrome and Thrombocytopenia

Öz

Down syndrome is a genetic disorder associated with vari- ous congenital anomalies and hematologic abnormalities. Various hematologic disorders such as transient leukemia- like proliferative disorders, increased incidence of leuke- mia, isolated thrombocytopenia and thrombocytosis were observed in Down syndrome. The etiology of thrombocyto- penia in Down syndrome is not exactly kwnown and there are limited data about this subject. In this review, we aimed to to evaluate the impact of the clinics of Down syndrome on thrombocytopenia and other hematologic parameters so as to emphasize necessary information related to the app- roach to Down syndrome and thrombocytopenia
