AIM OF THE WORK: This study aims to assess Growth differentiation factor-15 (GDF-15) level in Scleroderma patients and its relation to disease manifestations.
PATIENTS AND METHODS: This study included 55 scleroderma patients and 40 age and sex matched healthy volunteers. All patients were subjected to full history taking, thorough clinical examination, and laboratory investigations. GDF-15 serum levels were analyzed in patients and controls using human GDF-15 immunoassay Quantikine ELISA kit.
RESULTS: The GDF-15 serum level was significantly higher in Systemic sclerosis (SSc) patients in comparison to healthy control individuals, p-value = 0.004. In addition, the GDF-15 serum levels increased in a significant way in patients with diffuse SSc than those with limited SSc, p = 0.026. Also, we had discovered a significant positive correlation between serum GDF-15 levels and the modified Rodnan score of the SSc patients, r = 0.442, p = 0.001 and a significant association was found between high GDF-15 level and SSc patients with interstitial pulmonary fibrosis (IPF) as compared to healthy controls (p = 0.002). However, no significant difference was found between SSc patients without IPF and healthy subjects regarding GDF-15 level (p = 0.106).
CONCLUSION: GDF-15 serum levels were elevated in patients with SSc and correlated with the extent of skin fibrosis, and it was found to be higher in SSc patients with IPF. Such results may suggest a pivotal role of GDF-15 in fibrotic changes in SSc, and GDF-15 could be a treatment target in SSc patients in future.
