Glomerular Hyperfiltration and Renal Progression in Children with Autosomal Dominant Polycystic Kidney Disease

Abstract: SummaryBackground and objectives The purpose of this study was to determine whether glomerular hyperfiltration (GH) occurring early in autosomal dominant polycystic kidney disease (ADPKD) is indicative of more rapid disease progression in children.Design, setting, participants, & measurements One hundred eighty children with ADPKD (ages 4 to 18 years) with normal renal function were examined by renal ultrasound. Renal volume was calculated using a standard formula for a modified ellipsoid. Creatinine clearance… Show more

“…was evaluated in a cohort of 140 children with ADPKD followed longitudinally for a median of 5.8 years. 32 The subset of 32 children with glomerular hyperfiltration showed a higher rate of growth in TKV (corrected for body surface area) over 5 years and a faster decline in renal function than children without glomerular hyperfiltration. Because the final CrCl measures were similar in the two groups of children, it is unclear whether hyperfiltration translates into an earlier onset of ESRD.…”

“…Optymalnym postępowaniem w tej chorobie jest działanie mające na celu spowolnienie jej postępu jeszcze przed wzrostem stężenia kreatyniny w surowicy. Wskazane jest wprowadzenie interwencji terapeutycznych mają-cych na celu spowolnienie choroby, zanim dojdzie do całkowitego zniszczenia czynnego miąższu nerek przez powiększające się torbiele [12]. Trwają prace nad określeniem bardziej czułych markerów progresji tej choroby, tak aby łatwiej było wychwycić pacjentów ze zwiększonym ryzykiem szybkiego postępu niewydolności nerek lub innych powikłań [13,17,18,19].…”

“…Podobne wyniki uzyskali naukowcy amerykańscy, którzy zbadali 108 dzieci z ADPKD w wieku 4-18 lat. Udowodnili oni zależność pomiędzy obecnością hiperfiltracji a tempem progresji choroby, definiowanej jako powiększanie się nerek i zmniejszanie się filtracji kłę-buszkowej w trakcie pięcioletniej obserwacji [12]. Fick-Brosnahan i wsp., badając grupę 312 dzieci ze 131 rodzin z ADPKD, stwierdzili przyrost całkowitej objętości nerek już w 2-letnim okresie obserwacji [13], podobnie jak Chen D. i wsp., którzy poddali analizie 541 chińskich pacjentów z ADPKD w wieku 4-77 lat, udowadniając wzrost całkowitej objętości nerek po średnio 14 miesiącach obserwacji [28].…”

“…But this is very likely due to the non-GFR determinants of cystatin C being predictive of morbidity and mortality rather than just improved estimation of GFR by cystatin C. First, an elevated cystatin C level is just as predictive of mortality in persons without CKD (in whom GFR variation is physiologic) as it is in persons with CKD (in whom GFR variation is pathologic) (6). Second, hyperfiltration by mGFR or urinary creatinine clearance is associated with CKD risk factors and complications (obesity, diabetes, hypertension, left ventricular hypertrophy) (20)(21)(22)(23)(24), with developing albuminuria (25)(26)(27)(28), with structural abnormalities in the kidney (cysts, enlarged kidneys, and decreased glomerular density) (29)(30)(31)(32)(33), and with subsequent GFR decline and ESRD (29,34,35). Although eGFR Cr also identifies hyperfiltration as an increasedrisk state (16,24,28,35,36), eGFR Cys identifies hyperfiltration as a low-risk state (Figure 3) (16,23,24,35).…”
