Qhov no yog ib feem ntawm qhov tshwm sim ntawm cov cuab yeej txwv muaj uas yuav cia siab (xav tau) kev nce qib albuminuria.
Kev cuam tshuam cov tshuaj pharmacological yav dhau los nrog raum thiab cov tshuaj cardioprotective yuav ua rau muaj kev ncaj ncees nyob rau hauv cov ntsiab lus nyob rau theem pib ntawm kev pheej hmoo cardiorenal yog tias cov kev sim tshuaj ntsuam pom tau zoo dua. Txawm li cas los xij, kev ua tiav ntawm cov kev sim tshuaj no yuav nyob ntawm qhov kev txhawb nqa ntawm cov neeg koom nrog kev pheej hmoo siab dua thiab kev nkag siab zoo dua ntawm cov xwm txheej molecular uas piav qhia vim li cas albuminuria kev nce qib sib txawv ntawm cov kev kawm categorized hauv tib pab pawg kho mob raws li hauv paus hauv UACR, ntshav qab zib, ntshav siab lossis eGFR.

Qhov muaj nyob ntawm cov lus nug uas tsis tau daws teeb meem no tuaj yeem ua rau muaj kev nkag siab tsis txaus ntawm cov xwm txheej molecular
cuam tshuam nrog kev txhim kho albuminuria. Nyob rau hauv cov xwm txheej nyuaj no, tus cwj pwm ntawm cov xwm txheej molecular tuaj yeem pab ua kom muaj kev pheej hmoo ntawm kev mob plawv thaum ntxov thiab hauv kev txiav txim siab cov txheej txheem molecular uas ua rau kev nce qib albuminuria. Thaum cov kev tshawb fawb molecular hauv cov ntsiab lus normoalbuminuric nrog rau lub raum kev ua haujlwm tsis txaus, cov txheej txheem biology tsis ntev los no tau tso qee lub teeb hauv thaj chaw no.
In hypertensive subjects with normoalbuminuria under chronic renin-angiotensin system (RAS)blockade,>2500 urinary proteins tau txheeb xyuas los ntawm qhov tsis pom kev loj spectrometry. Cov qauv ntawm cov zis sib txawv hauv cov neeg mob uas muaj normoalbuminuria nyob rau hauv qhov siab-ib txwm (UACR 10-30} mg / g) los ntawm cov neeg uas muaj UACR<10 mg/g="" [7].="" alpha-1="" antitrypsin(a1at),="" kininogen-1="" (kng1),="" and="" vitamin="" d-binding="" protein="" (vtdb)="" were="" differentially="" present="" in="" urine="" and="" also="" differentially="" expressed="" in="" human="" kidneys="" and="" aorta="" samples,="" suggesting="" that="" early="" renal="" and="" vascular="" damage="" may="" be="" molecularly="" reflected="" in="" the="" urine="" of="" patients="" with="" normoalbuminuria.="" the="" unparalleled="" value="" of="" proteomics="" was="" also="" evidenced="" by="" the="" characterization="" and="" clinical="" development="" of="" ckd273,="" a="" ckd="" risk="" score="" based="" on="" the="" measurement="" of="" 273="" urinary="" peptides="" that="" independently="" predicted="" future="" development="" of="" microalbuminuria="" in="" type="" 2="" diabetic="" patients="" with="" normoalbuminuria="" as="" well="" as="" loss="" of="" gfr="" in="" patients="" with="" normoalbuminuria="" and="" egfr="" above="" 60="" ml/min/1.73="" m²,i.e.="" in="" patients="" not="" fulfilling="" current="" criteria="" to="" diagnose="" ckd="">10>

Cov zis concentration ntawm metabolites 3-ureidopropionate, oxaloacetate, thiab guanidinoacetate poob qis, thaum malate nce hauv cov neeg mob nrog microalbuminuria: thiab hauv cov neeg mob uas muaj normoalbuminuria nyob rau hauv qhov siab-ib txwm albuminuria ntau piv nrog cov neeg uas muaj qis albuminuria (UACR).<10 mg/g)[10].="" nine="" metabolites="" previously="" associated="" with="" cardiorenal="" risk="" were="" also="" altered="" in="" the="" high-normal="" albuminuria="" range:="" 2-hydroxyphenyl="" acetic="" acid,="" glutamic="" acid,="" n-acetylneuraminic="" acid,="" pipecolic="" acid,="" pyruvic="" acid,="" and="" scylloinositol="" increased,="" and="" α-ketoglutaric="" acid,="" y-aminobutyric="" acid,="" and="" n-phenylalanine="" decreased="" [11].="" the="" presence="" of="" these="" metabolites="" in="" the="" urine="" together="" with="" increased="" levels="" of="" fatty="" acids="" and="" fatty="" acid-binding="" protein-1="" (fabp1),="" and="" alterations="" in="" clathrin-mediated="" endocytosis="" signaling,="" is="" consistent="" with="" defective="" tubular="" reabsorption="" and="" tubular="" damage="" caused="" by="" fatty="" acid="" overload,="" impaired="" mitochondrial="" β-oxidation,="" peroxisome="" proliferator-activated="" receptor="" (ppar)activation="" or="" tricarboxylic="" acid="" cycle="" dysregulation="" (figure="" 1).="" these="" findings="" fit="" well="" with="" evidence="" that="" proximal="" tubular="" injury="" induced="" by="" glucose="" overload,="" albumin,="" and="" its="" ligands,="" or="" other="" stressors,="" leads="" to="" ckd="" progression[12,13].="" in="" proteinuric="" conditions,="" albumin-bound="" fatty="" acids="" may="" contribute="" to="" proximal="" tubule="" fatty="" acid="" overload,="" favoring="" lipotoxicity,="" oxidative="" stress,="" and="" impaired="" proximal="" tubule="" function="" [14].="" in="" this="" line,="" increased="" urinary="" fatty="" acids="" were="" strongly="" correlated="" with="" tubulointerstitial="" injury="" and="" proteinuria="">10>
Albuminuria yog ob qho tib si ib qho cim ntawm glomerular tsis ua haujlwm thiab ua rau muaj kev raug mob ntawm cov tubular ze ze [16]. Txawm li cas los xij, cov cim kev raug mob tshwj xeeb (mob raum raug mob molecule-1(KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), (FABP), thiab N-acetyl- -D-glucosaminidase ( NAG)) tsis tau ntxiv rau qhov kev pheej hmoo stratification rau CKD kev nce qib ntawm cov ntaub ntawv muab los ntawm UACR thiab eGFR hauv cov neeg mob laus nrog eGFR 20-70 mL/min/1.73 m2² thiab UACR 53.0 mg/g 【 interquartile range (IQR)5.6-503.1] [17]. Qhov no yuav qhia tias UACR nws tus kheej twb tau muab cov ntaub ntawv hais txog tubular kev raug mob ntawm tes pab txhawb rau CKD kev loj hlob uas tsis tau txhim kho ntxiv los ntawm kev ntsuam xyuas lwm yam biomarkers ntawm tubular raug mob.Txawm li cas los xij, hauv cov menyuam yaus uas muaj eGFR 30-90 mL/min/1.73 m² thiab UACR 57.8 mg/g (IQR 8.8-312), zis EGF, KIM-1, monocyte chemoattractant protein-1 (MCP-1) thiab -1 microglobulin tau txuam nrog nrog CKD kev loj hlob tom qab kev hloov pauv ntau yam [18].Qhov no qhia tias cov cim tso zis ntawm tubular cell raug mob yuav ntxiv cov ntaub ntawv rau qhov muab los ntawm albuminuria nyob rau hauv lub qhov rais twv ua ntej (hnub nyoog yau thiab siab dua eGFR).

Hauv kev xaus, nyob rau hauv kev kho mob ntawm normoalbuminuria, ntxiv stratification ntawm kev pheej hmoo tuaj yeem ua tau los ntawm kev siv cov biomarkers tshiab txheeb xyuas los ntawm cov txheej txheem biology. Cov cim no zoo ib yam nrogcev cevkev raug mob, o, hloov lub cev tiv thaiv kab mob, thiab oxidative kev nyuaj siab. Multicentric loj soj ntsuam cohorts yuav tsum validate cov biomarkers, thiab qhov no yuav tsum tau ua raws li los ntawm kev soj ntsuam kev sim uas cuv npe kawm normoalbuminuric cov neeg mob uas khaws cia raum tab sis muaj kev pheej hmoo ntawm cardiorenal kev pheej hmoo raws li tshiab biomarkers thiab randomize lawv mus rau thaum ntxov kev cuam tshuam los yog placebo. Tsuas yog cov ncauj lus kom ntxaws txog kev txhim kho kev kho mob yuav tso cai rau kev txheeb xyuas ntxov thiab kev cuam tshuam tsim nyog los ua kom muaj kev cuam tshuam los ntawm kev nce thoob ntiaj teb lub nra ntawm CKD thiab nws cov txiaj ntsig tsis zoo ntawm cov hlab plawv.
