Reninom kao uzrok teške hipertenzije i lošeg ishoda trudnoće mlade žene
Sažetak
Uvod. Jukstaglomerularni ćelijski tumor (JGĆT) ili reninom је veoma redak uzrok hipertenzije kod mladih ljudi. Najvažnija je rana dijagnoza koja se postavlja na osnovu kliničke prezentacije, hormonskih i radioloških nalaza, pre svega kompjuterizovane tomografije (KT) i magnetne rezonance (MR). Finalna potvrda dijagnoze JGĆT je prisustvo lateralizacije plazma reninske aktivnosti (PRA) tokom selektivnog uzorkovanja krvi iz renalne vene. Prikaz slučaja. Prikazan je tipičan slučaj mlade žene sa JGĆT koji se prvi put manifestovao ozbiljnom hipertenzijom tokom trudnoće i bio uzrok smrti ploda. Nakon pobačaja dijagnoza JGĆT postavljena je na osnovu CT pregleda i potvrđena je selektivnim uzorkovanjem krvi iz renalne vene. Nakon parcijalne nefrektomije došlo je do normalizacije vrednosti krvnog pritiska i vrednosti kalijuma u serumu. Zaključak. Na JGĆT treba misliti u diferencijalnoj dijagnozi ozbiljne hipertenzije tokom trudnoće kao i kod mladih ljudi (naročito žena) sa hipokalijemijom i sekundarnim hiperaldosteronizmom nakon isključenja drugih uzroka kao što je renalna arterijska stenoza. Dinamski kontrastni KT, MR i selektivno uzorkovanje krvi iz renalne vene najvažnije su procedure u postavljanju dijagnoze JGĆT.
