Although complex approaches in haematopoietic stem cell transplantation (aHSCT) improved substantially in the last decades, considerable proportion of patients still suffer from life-threatening complications including graft versus host disease (GvHD). Great effort has therefore been dedicated to identification of biomarkers of the aHSCT outcome. Recently, prognostic scores for the prediction of GvHD and non-relapse mortality based on circulating molecules, such as tumour necrosis factor receptor-1, IL-33receptor (ST2) and regenerating islet-derived 3-alpha were proposed and evaluated in multicentre studies. Furthermore, several biomarkers, for example, ST2, represent promising targets for therapeutic intervention in severe GvHD. These results bring us closer to the clinical strategies to effectively control complications following aHSCT, and therefore to the tailored stem cell therapy with higher benefits for the patients.

A Euro-Lupus regimen of low-dose intravenous cyclophosphamide (CFA) is commonly used to treat severe organ manifestations of systemic lupus erythematosus (SLE), particularly lupus nephritis (LN). There are no data on the distributions and dynamics of immune cell populations in patients with various treatment outcomes. The circulating immune cells of 11 female SLE patients were assessed before and after Euro-Lupus regimen (cumulative dose of 3000 mg CFA) by flow cytometry together with those of 16 healthy women. A subanalysis was performed in LN patients who achieved complete remission (CR; n = 3), partial remission (PR; n = 4), and no response (NR; n = 2). In SLE, the Euro-Lupus regimen decreased the percentage and absolute count of B cells; increased the percentage of CD8+ T cells, T regulatory cells, neutrophils, and monocyte subsets; and activated T and NK cells compared to healthy controls (P < 0.050). Patients with LN achieving CR had significantly lower proportions of CD27+ B memory cells compared to poor responders (PR/NR, P = 0.035). The post-treatment percentages and absolute numbers of B cells, T cells, NK cells, monocytes, and neutrophils showed high inter-individual variability with no association with treatment outcome. Our pilot study revealed the dynamics of changes in immune cell populations in SLE patients during a Euro-Lupus regimen, mainly the lowering of B cells. In LN patients who achieved CR, a lower proportion of CD27+ B memory cells was evident compared to poor responders (PR/NR). Further studies on usefulness of monitoring immune cells for treatment response prediction on larger cohorts are needed.
