- Heart failure (HF) affects millions of older individuals in both developed and low/middle-income countries. Serum galectin-3 levels have been shown to have prognostic value. However, its use as a diagnostic biomarker has not been explored. The aim was to establish a saliva galectin-3 reference range and to demonstrate the potential diagnostic utility of salivary and serum galectin-3 levels in assessing HF.
- Blood and saliva samples were collected from age-matched healthy controls (n=51) and patients with HF (n=63). Customised immunoassays were developed to quantify salivary galectin-3 levels. The diagnostic performances of these assays were evaluated by receiver operator characteristic (ROC) curves analysis.
- The galectin-3 concentrations were significantly elevated in saliva and serum samples of patients with HF compared with controls (p<0.001 and p<0.0001, respectively). Using ROC curve analysis, both serum and salivary galectin-3 gave area under the curve (AUC)=0.86 and AUC=0.73, respectively. There was also a significant correlation (r=0.4, p<0.01) between serum and salivary galectin-3 levels.
- For the first time, we have quantified galectin-3 levels in human saliva and have demonstrated potential clinical utility in diagnosing HF. Further, larger multicentre clinical trials are needed before salivary galectin-3 levels can be implemented in a clinical setting.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
