| Abstract | UVOD: Republika Hrvatska sa 17,7% stanovnika u dobi ≥65 g. spada u skupinu starih populacija. Sa starenjem se smanjuje funkcionalni kapacitet bubrega. Podataka o učestalosti KBB u starijoj populaciji za našu zemlju nema.
CILJ ISTRAŽIVANJA: Cilj rada bio je po prvi puta u Republici Hrvatskoj odrediti učestalost KBB i čimbenika rizika za njezin razvoj, te usporediti Cockroft-Gaultovu, MDRD i CKD-EPI formulu u osoba starije dobi.
ISPITANICI I METODE: Rad je dizajniran kao epidemiološka studija. Istraživanjem je obuhvaćeno 250 ispitanika iz Domova umirovljenika i 250 iz Domova zdravlja Grada Zagreba u dobi ≥65 g. Svakom ispitaniku uzeta je anemneza i izvršen je pregled. Iz uzoraka krvi i urina određeni su kreatinin, ukupni kolesterol, trigliceridi, krvna slika i proteinurija. Izračunata je GF pomoću Cockcroft-Gaultove, MDRD i CKD-EPI formule.
REZULTATI: U skupini je bilo 80% žena i 20% muškaraca, prosječne dobi 78,2 g. Dobna struktura razlikovala se s obzirom na mjesto regrutacije. Ističe se veliki udio ispitanika u dobi ≥80.g. GF<60 ml/min/1,73 m2 imalo je >75% ispitanika, a GF<45 ml/min/1,73 m2 22-42% ispitanika. Povišen serumski kreatinin imalo je 26%, proteinuriju 18%, a anemiju 10% ispitanika. Nađen je značajan udio ispitanika s neprepoznatom i/ili nereguliranom šećernom bolesti, arterijskom hipertenzijom i hiperlipidemijom. ITM ≥25 kg/m2 imalo je 69,8%.
ZAKLJUČAK: Učestalost smanjene bubrežne funkcije u ispitivanoj populaciji znatno je veća nego što se navodi u literaturi za stariju populaciju. Serumski kreatinin nije dobar pokazatelj bubrežne funkcije u starijih. Značajan je udio ispitanika s neprepoznatom i loše reguliranom šećernom bolesti, hipertenzijom i hiperlipidemijom. |
| Abstract (english) | INTRODUCTION: With 17.7% inhabitants aged ≥65 y population of Croatia is old.
Decrease of kidney function is a part of ageing process.
AIM: The aim of this study was to examine the prevalence of chronic kidney disease
and its risk factors in elderly Croatian population for the first time, and also to compare Cockcroft-Gault, MDRD and CKD-EPI formula in elderly.
PATIENTS AND METHODS: Study was designed as epidemiological study. 250 patients were recruited in Nursing homes, and 250 in General practice offices in the City of Zagreb, all of them aged ≥65 y. Medical history and short examination were performed. Blood and urine samples were analyzed for serum creatinine, cholesterol, tryglicerids, proteinuria and red blod count. Glomerular filtration rate was calculated using Cockcroft-Gault, MDRD i CKD-EPI formula.
RESULTS: There were 80% females and 20% males, average age was 78.2 y. Age structure differed depending on recruitment place, and significant number of participants were aged ≥80. GFR<60 ml/min/1,73 m2 was found in >75%, and GF<45 ml/min/1,73 m2 in 22-42% participants. Only 26% participants were found to have increased serum creatinine level, 18% had proteinuria and 10% anemia. Significant number of participants had unrecognized and/or poorly regulated diabetes, hypertension and hyperlipidemia. BMI ≥25 kg/m2 was found in 69.8%.
CONCLUSION: Prevalence of decreased renal function in our population was significantly greater when compared to other published studies performed in elderly. Serum creatinine is not adequate marker to assess renal function in elderly. There is significant number of participants with unrecognized and poorly regulated diabetes, hypertension and hyperlipidemia. |
