Abstract

Despite its invasive character, bone biopsy followed by histomorphometry remains the gold standard for diagnosing and classifying many metabolic bone diseases. However, the interpretation of histomorphometric parameters requires comparison with average values obtained from a proper control group, which are only available for some populations, and reference standards still need to be published. Therefore, our objective was to estimate average values for bone histomorphometric parameters overall, by age, gender, and race (White and Black) categories of healthy adult individuals, based on a systematic review and meta-analysis of clinical studies. Relevant studies published in English with available results until December 2020 were identified by PubMed (Medline) search and consulting experts in the field. Out of 447 potentially relevant studies, 37 met the inclusion criteria. Meta-analysis using fixed-effects models was used to pool mean estimates and 95% confidence intervals (CI) for 16 bone histomorphometry parameters.

An age-by-gender trend was observed in most histomorphometry parameters. The mean estimates of bone volume/tissue volume (BV/TV), trabecular thickness (Tb.Th), and trabecular number (Tb.N) decreased. In contrast, trabecular separation (Tb.Sp) increased from the youngest to the oldest age categories in both genders. Osteoblast surface (Ob.S/BS) and osteoclast surface (Oc.S/BS) decreased across all age categories in males. Mineralizing surface (MS/BS) increased from the youngest to the oldest age categories in females, while mineralization lag time (Mlt) increased in both genders. Furthermore, gender and race had a significant effect on several histomorphometry parameters.

In conclusion, this meta-analysis provided mean estimates for normal values of histomorphometric parameters that clinicians may use when evaluating bone biopsies in patients. This enables the direct comparison of patients' histomorphometric values with the suitable reference group regarding age, gender, and race.

健康人髂骨的组织形态计量参数：系统回顾和荟萃分析。

尽管骨活检具有侵入性，但其后的组织形态测量仍是诊断和分类许多代谢性骨病的黄金标准。然而，组织形态测量参数的解释需要与适当的对照组获得的平均值进行比较，而对照组只适用于某些人群，参考标准仍有待公布。因此，我们的目标是在对临床研究进行系统回顾和荟萃分析的基础上，按照健康成年人的年龄、性别和种族（白人和黑人）类别，估算出骨组织形态测量参数的总体平均值。通过 PubMed（Medline）检索和咨询该领域的专家，确定了在 2020 年 12 月之前发表的相关英文研究。在 447 项可能相关的研究中，有 37 项符合纳入标准。采用固定效应模型进行元分析，汇集了16个骨骼组织形态测量参数的平均估计值和95%置信区间（CI）。在大多数组织形态测量参数中都观察到了按性别划分的年龄趋势。骨体积/组织容积（BV/TV）、骨小梁厚度（Tb.Th）和骨小梁数量（Tb.N）的平均估计值有所下降。相比之下，从最年轻到最年长的年龄组别中，男女两性的骨小梁分离度（Tb.Sp）都有所增加。男性的成骨细胞表面（Ob.S/BS）和破骨细胞表面（Oc.S/BS）在所有年龄段都有所下降。女性的矿化表面（MS/BS）从最小年龄段到最大年龄段都有所增加，而矿化滞后时间（Mlt）在男女两性中都有所增加。此外，性别和种族对几个组织形态测量参数也有显著影响。总之，这项荟萃分析提供了组织形态计量参数正常值的平均估计值，临床医生在评估患者的骨活检结果时可以使用这些参数。这样就可以将患者的组织形态测量值与年龄、性别和种族方面的合适参照组进行直接比较。

期刊介绍： BONE is an interdisciplinary forum for the rapid publication of original articles and reviews on basic, translational, and clinical aspects of bone and mineral metabolism. The Journal also encourages submissions related to interactions of bone with other organ systems, including cartilage, endocrine, muscle, fat, neural, vascular, gastrointestinal, hematopoietic, and immune systems. Particular attention is placed on the application of experimental studies to clinical practice.
