Abstract
Background
Haemophilic arthropathy (HArt) is a serious complication in patients with hemophilia. Early diagnosis and treatment are essential to minimise the development of HArt. The use of biomarkers may improve early diagnosis of HArt. Circulating microRNAs (miRNAs) are small, non-coding RNAsthat regulate gene expression, and are being investigated as promising biomarkers due to their role in joint and bone metabolism.
Aims
To investigate differential expression of miRNAs and their relationship to arthropathy in patients with hemophilia A.
Methods
miRNA expression was examined in a pilot study followed by a validation study (100 hemophilia A patients with [n = 83] and without HArt [n = 17], 14 controls). Differential miRNA expression was investigated using real-time quantitative PCR.
Results
The pilot study identified 2 miRNAs differentially expressed in patients with Hart (Pettersson score ≥ 1), after adjusting for the false discovery rate (FDR). The validation study evaluated these 2 miRNAs. The results demonstrated that two miRNAs (miR- 208a-3p and 524-3p) were significantly underexpressed in plasma of patients with HArt compared to patients without arthropathy, with FDR <0.05 (Fig. 1). In addition, 3 miRNAs (130a-3p, miR- and 506-3p) were significantly underexpressed in patients with moderate HArt (Pettersson score 4 to 7).
Conclusions
In this proof of concept study we identified a signature of 5 circulating miRNAs associated with Hart with potential as diagnosis tools for HArt. These miRNAs are potential negative regulators of gene expression, suggesting their activity in HArt by interfering with osteoblastic (miR- 208a-3p) and osteoclastic (miR-506-3p) differentiation to impair bone mineralization and remodeling processes, or regulating chondrogenesis (miR-335-5p). miRNAs associated with earlier stages of HArt will be further investigated in a sub-study of the prospective clinical trial PROVE, which will investigate the effects of long-term prophylaxis with simoctocog alfa versus emicizumab in adults with hemophilia A.
