Yenidoğanda Hipoglisemi, Konjenital Hipotiroidi ve Konjenital Adrenal Hiperplazinin Tanı ve Tedavisi
Özet
Hipoglisemi, yenidoğan döneminde en sık karşılaşılan metabolik sorunlardan olup, semptomsuz seyredebilmesi tanıda gecikme riskini artırmakta, erken tanı konup uygun tedavi edilmediğinde de kalıcı nörolojik hasara yol açabilmesi nedeniyle oldukça önemlidir. Tiroid hormonu intrauterine dönemden postnatal döneme uzanan ve yaşamın tüm aşamalarında vazgeçilmez metabolik rolüyle özellikle santral sinir sistemi gelişiminde, büyüme gelişmenin sağlanmasında hayati önemi vardır. Tiroid bezinin yapısal ya da işlevsel sorunları konjenital hipotiroidi (KH) tablosuyla karşımıza çıkmakta ve özellikle nöromotor gelişimin sağlıklı olabilmesi için mümkün olan en kısa sürede tanı konulup uygun tedavisinin başlanması gerekmektedir. Benzer şekilde konjenital adrenal hiperplazi (KAH) adrenal kortekste gerçekleşen, kolesterolden glukokortikoid ve mineralokortikoid sentezinde gerekli enzimlerden veya kofaktör proteinlerden herhangi birinin eksikliği ile oluşan klinik tablo olup en sık görülen şekli klasik tuz kaybı ile seyreden KAH’nin klinik bulguları yenidoğan döneminde gözlenmekte, tanı ve tedavideki gecikmeler hayatı tehdit eden klinik tablolara sebep olmaktadır.
Hypoglycemia is one of the most common metabolic disorders encountered during the neonatal period. Its frequently asymptomatic presentation increases the risk of delayed diagnosis, and when not recognized and treated promptly, it may result in permanent neurological sequelae. Therefore, early detection and appropriate management are of critical importance. Thyroid hormones play an indispensable metabolic role from the intrauterine period through postnatal life and across all stages of human development. They are particularly essential for central nervous system maturation as well as normal growth and development. Structural or functional abnormalities of the thyroid gland may lead to congenital hypothyroidism (CH), a condition that requires prompt diagnosis and timely initiation of treatment to ensure optimal neurodevelopmental outcomes. Similarly, congenital adrenal hyperplasia (CAH) comprises a group of disorders resulting from deficiencies in enzymes or cofactor proteins required for the synthesis of glucocorticoids and mineralocorticoids from cholesterol within the adrenal cortex. The most common form, classic salt-wasting CAH, typically manifests during the neonatal period. Delays in diagnosis and treatment may lead to life-threatening clinical complications.
