Hypochromic Red Cells Identified as Potential Biomarker for Mortality Risk Among Systemic Sclerosis Patients
Germany: A new study has found that hypochromic red cells (HRC) may be used as a biomarker for predicting mortality risk among systemic sclerosis (SSc) patients according to a study published in BMC: Arthritis Research and Therapy.
The study, conducted by a team of researchers in Germany, aimed to investigate the prognostic value of % HRC in SSc patients who were screened for pulmonary hypertension (PH).
The retrospective study included 171 SSc patients, out of the 280 screened for PH, with available data on iron metabolism. The study analyzed clinical characteristics, as well as laboratory and pulmonary functional parameters, to determine their association with the prognosis of SSc using uni- and multivariable analysis. The patients were followed for an average of 2.4 ± 1.8 years.
The study concluded with the following clinical takeaways:
- 1.77% of the patients had limited cutaneous SSc, 65 had manifest PH, and 73 had pulmonary fibrosis.
- 2.HRC > 2% at baseline was significantly associated with worse survival in both uni- and multivariable analyses, independent from the presence of PH or pulmonary parenchymal manifestations.
- 3.The combination of HRC > 2% and low diffusion capacity for carbon monoxide (DLCO) ≤ 65% predicted was significantly associated with survival.
Patients with SSc are frequently affected by iron deficiency, particularly those with PH, and the first data indicate the prognostic importance of HRC > 2% among patients with PH. Although this is the first study to report on the potential use of HRC as a biomarker for SSc patients, the researchers emphasize that larger studies are required to confirm these findings.
The study’s lead author, Dr. Panagiota Xanthouli, emphasized the importance of these findings for the management of SSc patients, stating that “the combination of HRC > 2% and DLCO ≤ 65% predicted is a simple and easily obtainable marker, which could be easily implemented into clinical practice and help identify patients at higher risk of mortality.”
