Abstract

Detailed knowledge of biological variation can facilitate accurate interpretation of clinical pathology parameters. A recent biological variation study in Asian elephants (Elephas maximus) found that hematology parameters had high individuality, which suggests that population-derived reference intervals may be an insensitive diagnostic tool. In elephant medicine, sensitive hematology-related diagnostics are crucial for clinical decision-making, particularly in elephants at risk for elephant endotheliotropic herpesvirus hemorrhagic disease (EEHV-HD). The objective of this study was to assess biological variation of hematology parameters in African elephants to determine whether population-derived reference intervals are a sensitive diagnostic tool for interpreting results and to provide a useful alternative. Eight healthy African elephants had blood collected under behavioral training every other week for 8 wk. Complete blood cell count (CBC) analysis was performed in duplicate to assess analytical variation. Previous methods were used to determine between-individual variation, within-individual variation, index of individuality, and reference change values (RCV). This study found that most hematology parameters displayed intermediate-to-high individuality, which suggests that alternatives to population-derived reference intervals are necessary to detect pathologic changes. To test the results of our biological variation data, a case of EEHV-HD was retrospectively evaluated. Individual normal values and calculated RCV detected a clinically significant monocytopenia, leukopenia, and thrombocytopenia associated with EEHV2 viremia. However, none of these parameters fell outside a population-derived reference interval. This study highlights the utility of biological variation in clinical decision-making and demonstrates that individual normal values and RCV may be important diagnostic tools for CBC interpretation in African elephants.

非洲象(loxodonta africana)血液学参数的生物变异及临床应用。
详细了解生物变异有助于准确解释临床病理参数。最近对亚洲象(Elephas maximus)的生物变异研究发现,血液学参数具有高度个体性,这表明源自种群的参考区间可能是一种不敏感的诊断工具。在大象医学中,敏感的血液学相关诊断对临床决策至关重要,尤其是对有大象内皮细胞疱疹病毒出血性疾病(EEHV-HD)风险的大象。本研究的目的是评估非洲象血液学参数的生物变异,以确定源自种群的参考区间是否是解释结果的灵敏诊断工具,并提供一种有用的替代方法。8 头健康的非洲象在行为训练下每隔一周采集一次血液,共持续 8 周。全血细胞计数(CBC)分析重复进行,以评估分析差异。以前的方法用于确定个体间差异、个体内差异、个体指数和参考变化值(RCV)。本研究发现,大多数血液学参数显示出中等至较高的个体差异,这表明有必要采用替代人群参考区间的方法来检测病理变化。为了检验我们的生物变异数据结果,我们对一例 EEHV-HD 病例进行了回顾性评估。个体正常值和计算的 RCV 检测出与 EEHV2 病毒血症相关的临床显著的单核细胞减少、白细胞减少和血小板减少。但是,这些参数都没有超出人群参考区间。这项研究强调了生物变异在临床决策中的实用性,并证明了个体正常值和 RCV 可能是解释非洲象 CBC 的重要诊断工具。

期刊介绍: The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers. The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution. Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
