Kačių kraujyje esančių kreatinino ir šlapalo koncentracijų vertinimas sergant lėtiniu inkstų nepakankamumu / Creatinine and urea, contained in feline blood concentration, evaluation in patients with chronic renal failture

Pranckutė, Ieva 05 March 2014 (has links)
Darbo apimtis: 50 p. Jame 9-ios lentelės, 28-i paveikslai. Literatūros šaltiniai: knygų – 6, mokslinių straipsnių – 21, Internetinių šaltinių – 1. Tikslas: Nustatyti kraujyje esančio kreatinino, šlapalo bei kitų medžiagų – alaninaminotransferazės, aspartataminotransferazės ir amilazės, koncentracijų kitimus katėms sergančioms lėtiniu inkstų nepakankamumu. Metodika: 2011 – 2013 m. „Kaivanos“ smulkių gyvūnų klinikoje buvo atliktas tyrimas, kuriame dalyvavo 50 lėtiniu inkstų nepakankamumu sergančių kačių. Joms buvo atlikta kraujo biocheminių rodiklių analizė (kreatinino, šlapalo, alaninaminotransferazės, aspartataminotransferazės ir amilazės) biocheminiu kraujo analizatoriumi Refloctron Plus Roche. WinExcel programa atlikta šių duomenų stasistinė analizė, vertinanat kačių kreatinino stadijų, amžiaus, lyties, kastracijos ir veislės įtaką sergant lėtiniu inkstų nepakankamumu. Atlikta požymių koreliacinė analizė ir vienfaktorinė dispersinė analizė. . Rezultatai, išvados:  Katės lėtiniu inkstų nepakankamumu serga gana retai – 5% iš visų 1183 (100%) klinikoje apsilankiusiųjų.  Sergamumui LIN gyvūno amžius, veislė, lytis pastebimos įtakos neturi. Tačiau imliausios yra 7 – 9 m. katės.  Kreatinino koncentracija tiksliai nusako ligos sunkumą ir priklauso tik nuo inkstų pažeidimo, kiti faktoriai jo kiekio svyravimams įtakos neturi.  Sergančių IV-a LIN stadija kačių buvo nustatyta daugiausia – 18 (36%).  Šlapalo kiekis kraujyje tiesiogiai korialiuoja su LIN stadija ir kreatinino...

Objective: To identify the variations in circulating creatinine, urea and other substances - alanine aminotransferase, aspartate aminotransferase, and amylase concentration in cats suffering from chronic kidney failure. Methodics: In 2011 – 2013 years on „Kaivana“ small animal clinic a study was conducted on 50 cats who had chronic renal insufficiency. For those cats were made a blood chemistry analysis (creatinine, urea, alanine aminotransferase, aspartate aminotransferase, and amylase) with blood chemistry analyzer Refloctron Plus Roche. WinExcel program performed the statistical analysis, the assessment of feline creatinine stage, age, sex, breed and castration effect on patients with chronic renal failure. We also conducted a correlation analysis features, and one factor analysis of variance. Results, Conclusions:  Cats with chronic renal failure suffer relatively rarely - 5%.  For the incidence of CRF, animal age, breed, sex has no significant influence. However, the most receptive cats are from 7 to 9 years of life.  Creatinine concentration accurately describes the severity of the disease and depends only on kidney damage and other factors it is not affected by fluctuations in volume.  Sick-IV stage of a CRF cat was found mainly - 18 (36%).  Urea levels directly correlated with the stage of CRF and creatinine. Also Urea is an informative setting... [to full text]

Biomarqueurs du risque cardiovasculaire en insuffisance rénale chronique / Biomarkers of cardiovascular risk in chronic kidney disease

Bargnoux, Anne-Sophie 14 December 2010 (has links)
Les maladies cardiovasculaires apparaissent précocement au cours de l'insuffisance rénale chronique (IRC) et représentent la première cause de mortalité. La 1ère étape pour apprécier la relation entre risque cardiovasculaire et progression de l'IRC consiste à améliorer l'estimation du débit de filtration glomérulaire (DFG). Nous avons donc évalué l'impact des conditions analytiques de mesure de la créatininémie et de la cystatinémie sur l'estimation du DFG. Les créatinines IDMS traçables (enzymatique et Jaffe compensé) améliorent l'estimation du DFG. Cependant, les méthodes enzymatiques non sensibles aux pseudochromogènes doivent être préférées. Concernant la cystatine C, nos résultats soulignent l'absence de standardisation du dosage. Chez des patients IRC non dialysés (stade I à V), nous avons identifié l'ostéoprotégérine (OPG) comme marqueur biologique de la présence de calcifications vasculaires. In vitro, nous avons démontré que le stress oxydant, majoré en présence de sérum urémique, jouait un rôle clé dans la transdifférenciation des cellules musculaires lisses vasculaires en ost oblastes. La mortalité en dialyse reste élevée et est largement dépendante des maladies cardiovasculaires. Il nous a donc paru nécessaire de rechercher les marqueurs pronostics et/ou d'en suivre l'évolution en transplantation. En dialyse, malgré une épuration significative par hémodiafiltration, les peptides natriurétiques sont des marqueurs du remodelage ventriculaire. La combinaison "NT-proBNP-CRP" est un puissant facteur pronostic de mortalité cardiovasculaire en hémodialyse. Après transplantation rénale, les calcifications vasculaires se stabilisent chez la majorité des patients et les taux d'OPG diminuent précocement. Les taux d'OPG sont significativement plus élevés chez les patients dont les calcifications progressent. Toutefois, seule l'intensité des calcifications avant transplantation permet de prédire la progression / Cardiovascular disease occurs in the early stage of chronic kidney disease (CKD) and is the leading cause of death. The first step, to appreciate the link between cardiovascular risk and CKD progression, is to improve glomerular filtration rate (GFR) estimation. We have therefore evaluated the impact of analytical conditions for creatinine and cystatin C measurement on estimated GFR. New creatinine ID-MS traceable methods (enzymatic and compensated Jaffe) improved estimation of GFR by predictive equations. However, enzymatic methods that are much less susceptible to interfere with non-creatinine chromogens may provide more reliable estimations of GFR. Regarding cystatin C, our results highlighted the lack of standardization. In non dialyzed CKD patients (stage I to V), we identified osteoprotegerin (OPG) as a biomarker for the presence of vascular calcification. In vitro, we demonstrated that oxidative stress, increased in the presence of uremi c serum, played a key role in the transdifferentiation of vascular smooth muscle cells into osteoblast-like cells. In dialysis, mortality is high and largely dependant on cardiovascular disease. We have therefore investigated prognostic markers and/or followed their evolution after transplantation. In dialysis, despite their removal by hemodiafiltration, natriuretic peptides could be potential markers of left ventricular remodelling. In addition, the combination of high CRP and circulating NT-proBNP dramatically impaired the hemodialysis survival rate. After renal transplantation, stabilization of vascular calcification was observed in the majority of patients and OPG levels are dramatically reduced. Despite a higher baseline OPG level in progressors vs. non-progressors patients, post transplant vascular calcification progression was only predicted by baseline score.
