Claims (14)
1. Fremgangsmåde til evaluering af pneumoni og akut dekompenseret hjertesvigt (ADHF) hos et individ, hvilken fremgangsmåde omfatter udførelse af en assay-fremgangsmåde, der er konfigureret til at detektere et ghrelinsignalpeptidfragment ifølge SEQ ID NO: 3 eller SEQ ID NO: 4 i en kropsfluidprøve opnået fra individet for at tilvejebringe et assay-resultat; og korrelering af assay-resultatet med tilstedeværelsen eller status for pneumoni og akut dekompenseret hjertesvigt (ADHF) hos individet.
2. Fremgangsmåde ifølge krav 1, hvor (a) korreleringstrinnet omfatter korrelering af assay-resultatet med én eller flere af risikostratificering, stadieinddeling, klassificering og monitorering af eksistensen eller status af pneumoni og ADFIF hos individet; (b) korreleringstrinnet omfatter tildeling af et behandlingsregimen til individet baseret på assay-resultatet; (c) korreleringstrinnet omfatter evaluering af et klinisk resultat efter et behandlingsregimen for pneumoni og ADFIF hos individet; og/eller (d) assay-resultatet er en målt koncentration af et ghrelinsignalpeptidfragment, og korreleringstrinnet omfatter sammenligning af koncentrationen med en tærskelkoncentration.
3. Fremgangsmåde ifølge krav 1 eller krav 2, hvor (a) individet udvælges til evaluering af pneumoni baseret på ét eller flere symptomer på pneumoni, herunder hoste med spytproduktion, feber, pleuraexsudat, skarp brystsmerte ved inspiration og stakåndethed; og/eller (b) individet udvælges for evaluering af ADFIF baseret på ét eller flere symptomer på ADFIF, herunder åndenød (dyspnø), ødem og træthed.
4. Fremgangsmåde ifølge krav 1 eller krav 2, hvor korreleringstrinnet omfatter vurdering af, om pneumonien og ADFIF bedres eller forværres hos individet baseret på assay-resultatet.
5. Fremgangsmåde ifølge krav 2(d), hvor tærsklen er en koncentration af ghrelinsignalpeptidfragmentet: (a) opnået fra individet på et tidligere tidspunkt; (b) opnået fra en normal individpopulation; (c) opnået fra en population med pneumonia og ADFIF; og/eller (d) udvalgt til at skelne fra en population af individer en første subpopulation med pneumoni og ADHF i forhold til en anden subpopulation, der ikke har pneumoni og ADHF.
6. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 5, hvor assay-fremgangsmåden omfatter et ghrelinsignalpeptidfragment-bindingsmiddel, der binder: (a) GHRsp (1-9) (SEQ ID NO: 3) eller (b) GHRsp (1-10) (SEQ ID NO: 4).
7. Fremgangsmåde ifølge krav 6, hvor niveauet af ghrelinsignalpeptidfragment detekteres i prøven ved binding af et ghrelinsignalpeptidfragment til et bindingsmiddel, der selektivt binder GHRsp (1-9) (SEQ ID NO: 3).
8. Fremgangsmåde ifølge krav 6 eller 7, hvor ghrelinsignalpeptidfragment-bindingsmidlet er et polyklonalt, monoklonalt, bispecifikt, kimærisk eller humaniseret antistof eller antigenbindingsfragment deraf.
9. Fremgangsmåde ifølge krav 8, hvor ghrelinsignalpeptidfragment eller bindingsmidlet er mærket med en detekterbar markør.
10. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 9, hvor den biologiske prøve er fra en kredsløbskilde, såsom blod, plasma, serum, spyt, interstitiel fluid eller urin, eller fra en vævsprøve.
11. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 10, hvor niveauet af ghrelinsignalpeptidfragment måles ved anvendelse af massespektroskopi eller ved anvendelse af et assay udvalgt fra RIA, ELISA, immunfluorometrisk assay og immunradiometrisk assay.
12. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 11, der endvidere omfatter måling af niveauet af én eller flere non-GHRsp-markører af pneumoni, ADHF eller pneumoni og ADHF, eventuelt hvor non-GHRsp-markøren er udvalgt fra gruppen bestående af procalcitonin (PCT), udløsende receptor udtrykt på myeloide celler-1, kreativt protein (CRP), immunglobuliner og proinflammatoriske cytokiner, hjerne-natriuretisk protein (BNP), N-terminalproBNP (NT-BNP), blod-urea-nitrogen (BUN), pankreatisk stenprotein og troponin.
13. Assay-fremgangsmåde til detektering af pneumoni og akut dekompenseret hjertesvigt (ADHF) hos et individ, hvilket assay omfatter: (a) binding af et ghrelinsignalpeptidfragment ifølge SEQ ID NO: 3 eller SEQ ID NO: 4 opnået fra eller i en biologisk prøve; og (b) bestemmelse af tilstedeværelsen eller mængden af bundet ghrelinsignalpeptidfragment; og (c) korrelering af tilstedeværelsen eller mængden af det bundne ghrelinsignalpeptidfragment med en reference- eller kontrolværdi; hvor en afvigelse i tilstedeværelsen eller mængden af bundet ghrelinsignalpeptidfragment i prøven fra reference- eller kontrolværdien indikerer, at individet har pneumoni og ADHF.
14. Assay-fremgangsmåde ifølge krav 13, hvor: (a) mængden af ghrelinsignalpeptidfragment højere end kontrolmængden indikerer pneumoni og ADHF; (b) fremgangsmåden anvendes til at evaluere eller monitorere et respons på behandling af pneumoni og ADHF hos et individ, hvor en ændring i det målte niveau af ghrelinsignalpeptidfragment fra kontrolniveauet indikerer et respons på behandlingen; og/eller (c) assayet omfatter måling af niveauet af ghrelinsignalpeptidfragment i talrige biologiske prøver individet.
