Ispitivanje nivoa leptina i grelina u serumu gojazne, normalno uhranjene i mršave dece
Sažetak
Uvod/Cilj. Homeostaza energije je balans između energetskog unosa i potrošnje energije. Leptin i grelin su dva oreksitropna hormona sa suprotnim efektom na homeostazu energije. Ispitivane su vrednosti leptina i grelina u serumu dece različititog tipa uhranjenosti. Metode. Kod 30 gojazne dece oba pola, uzrasta od 6 do 17,67 godina (srednja vrednost 13,04 ± 2,95 godine), određivane su vrednosti leptina i grelina u serumu, uz određivanje auksoloških parametara i pubertetskog statusa. Dobijeni rezultati su analizirani i upoređivani sa vrednostima istih parametara kod 33 normalno uhranjene i 25 mršave dece. Rezultati. Vrednosti odnosa grelin/telesna masa (TM) bile su najniže kod gojazne dece (21,75 ± 12,60 pg/mL/kg) što je statistički značajno različito u odnosu na vrednosti kod mršave i normalno ishranjene dece. Vrednost odnosa leptin/TM bila je statistički značajno veća kod gojazne dece (0.62 ± 0.86) u odnosu na normalno uhranjene (p < 0,01) i mršave (p < 0,001). Vrednosti leptina i grelina pokazale su različit profil kod gojazne, normalno uhranjene i mršave dece. U ispitivanim grupama dokazane su inverzne vrednosti odnosa grelin/leptin i leptin/grelin. Zaključak. Gojazna deca imaju značajno više vrednosti leptina, a mršava deca značajno više vrednosti grelina po kilogramu telesne mase u odnosu na ostalu decu. Rezultati ukazuju i na inverzni odnos grelina i leptina koji se pokazao kao klinički pouzdan pokazatelj prisustva gojaznosti ili neuhranjenosti kod dece, što je od velikog značaja, uzimajući u obzir velike varijacije u koncentraciji ovih hormona, ne samo prema telesnoj masi, već i prema uzrastu dece.
