Derivatives of Dehydroepiandrosterone in Obese and Their Changes During One-Day Starvation Test
DERIVÁTY DEHYDROEPIANDROSTERONU A JEJICH ZMĚNY BĚHEM TESTU JEDNODENNÍHO HLADOVĚNÍ
Východisko.
Vztahy dehydroepiandrosteronu (DHEA) a jeho metabolitu dehydroepiandrosteronsulfátu (DHEAS) k různým složkám metabolického syndromu X jsou poměrně velmi často diskutované v mnoha pracech. V poslední době se však zdá, že alespoň v některých případech (např. v imunitní odpovědi) jsou za některé účinky, původně připisované samotnému DHEA či DHEAS, zodpovědné hydroxyderiváty DHEA, a to především jejich 7-hydroxy formy. V této práci jsme nejprve v pilotní epidemiologické studii sledovali vztah 7-alfa a 7-beta-(OH)-DHEA k jednotlivým parametrům metabolického syndromu a obezitě.Metody a výsledky. Celkem jsme vyšetřili 68 pacientů (z toho 28 mužů) s prům. BMI 35,7±11,6 kg/m2 a věkem 42,6±11,1 let. Z hlediska metabolického syndromu stojí za zmínku především negativní korelace hladiny 7-beta-OH-derivátu a hladiny inzulinu (r=-0,28; p=0,03) a glykémií (r=-0,48; p

Overview
Background.
Relationship between dehydroepiandrosterone (DHEA), its sulphate (DHEAS) and various components of metabolic syndrome X have been recently discussed in several papers. Original only DHEA or DHEAS have been considered to be responsible for all of the effects. At present mainly DHEA hydroxyderivatives (particularly 7-hydroxyisometers) are assumed to be responsible for those effects.Methods and Results. 68 obese subjects (28 males) aged 42.6±11.1 years, with average BMI 35.7±11.6 kg/m2 were examined. Relationship between 7-alpha and 7-beta-(OH)-DHEA and various components of metabolic syndrome X have been followed in a pilot epidemiological study. Fluctuations of the hydroxyderivates level during one-day starvation test were investigated in a group of 11 obese females and compared with that of the control group (12 lean subjects with BMI 23.1±2.4 kg/m2). From the view of the metabolic syndrome X, the negative correlation between the serum levels of 7-beta-(OH)-DHEA and insulinemia (R=-0.28; p=0.23), glycemia (r=-0,48; p
