Abstract
Background: Chihuahua represents an increasingly widespread breed predisposed to cardiac disease. N-terminal pro-B-type natriuretic peptide (NT-proBNP) might be a useful point-of-care biomarker for dogs suspected of having heart disease, but breed differences have been reported. The urinary aldosterone-to-creatinine ratio (UAldo: C) appears to be a good indicator of renin-angiotensin-aldosterone system activity in dogs, but Chihuahuas showed significantly higher UAldo: C than other breeds. The objective of this study was to assess preliminary breed-specific reference intervals for NT-proBNP and UAldo: C in healthy Chihuahuas and evaluate sex differences in these parameters.
Results: Forty-three healthy Chihuahuas dogs were enrolled. The median NT-proBNP was 347 (125-515) pmol/L, and the median UAldo: C was 2.59 (1.57-4.61) µg/g. The NT-proBNP reference interval was 125 (90% CI 125-125) - 2121.4 (90% CI 941.6-2248) pmol/L. 91% of the Chihuahuas were below the nonbreed-specific cut-off (900 pmol/L). The UAldo: C reference interval was 0.6 (90% CI 0.5-0.9) - 16.8 (90% CI 10.9-27.4) µg/g. No significant sex differences in NT-proBNP or UAldo: C were found.
Conclusions: The median value, interindividual coefficient of variation and reference interval of NT-proBNP were in line with those reported for other small breeds. In contrast to previous studies, no sex differences in NT-proBNP were detected. As previously suggested, Chihuahuas seem to be characterized by higher values of UAldo: C than other breeds.
背景:吉娃娃犬是越来越普遍的易患心脏病的犬种。N 端前 B 型钠尿肽(NT-proBNP)可能是疑似患有心脏病的狗的一种有用的护理点生物标志物,但有报道称犬种之间存在差异。尿醛固酮与肌酐的比率(UAldo: C)似乎是狗体内肾素-血管紧张素-醛固酮系统活性的良好指标,但吉娃娃的 UAldo: C 明显高于其他品种。本研究的目的是评估健康吉娃娃犬 NT-proBNP 和 UAldo: C 的初步品种特异性参考区间,并评估这些参数的性别差异:结果:43 只健康的吉娃娃犬参加了研究。NT-proBNP 的中位数为 347 (125-515) pmol/L,UAldo: C 的中位数为 2.59 (1.57-4.61) µg/g。NT-proBNP 参考区间为 125(90% CI 125-125)-2121.4(90% CI 941.6-2248)pmol/L。91%的吉娃娃犬低于非品种特异性临界值(900 pmol/L)。UAldo:C 参考区间为 0.6(90% CI 0.5-0.9)-16.8(90% CI 10.9-27.4)微克/克。NT-proBNP和UAldo: C没有发现明显的性别差异:结论:NT-proBNP的中值、个体间变异系数和参考区间与其他小型犬种的报告一致。与之前的研究相比,NT-proBNP 没有发现性别差异。正如之前所说,吉娃娃犬的 UAldo: C 值似乎高于其他犬种。
