ABSTRACT
Mineralocorticoid receptor antagonists not only are used as a diuretics to treat essential hypertension, but also protect the heart and kidney by inhibiting inflammation and fibrosis. Since the discovery of spironolactone, the first generation of mineralocorticoid receptor antagonist, two types of non-steroid mineralocorticoid receptor antagonists (finerenone and esaxerenone) approved for clinical use have been developed, which have the advantages of high affinity, high selectivity and balanced distribution in heart and kidney, and can be used in clinic as a cardiorenal protective drug. In this paper, the development history of mineralocorticoid receptor antagonists was reviewed, and the pathophysiological mechanism of inflammation and fibrosis caused by mineralocorticoid receptors and the similarities and differences of different generations of mineralocorticoid receptor antagonists were analyzed. In particular, the phase III clinical research evidence of finerenone and esaxerenone was discussed. This paper also reviews the research progress of cardiorenal protection of non-steroid mineralocorticoid receptor antagonists in patients with chronic kidney disease.

<p><b>BACKGROUND</b>Autologous stem cell transplantation (ASCT) is a part of the standard induction therapy of multiple myeloma (MM). This case-controlled clinical trial aimed to further evaluate the therapeutic effects of ASCT as a consolidation therapy for MM and discuss factors influencing the prognosis.</p><p><b>METHODS</b>Clinical data of 70 patients diagnosed as MM who received ASCT as a consolidation therapy in our hospital between October 1998 and August 2010 were analyzed retrospectively (ASCT group). Other 70 MM patients receiving routine chemotherapy without ASCT (non-ASCT group) during the same period were used as controls. Differences in the degree and duration of remission, progression-free survival (PFS) and overall survival (OS) were compared to explore factors that may influence the prognosis.</p><p><b>RESULTS</b>The median follow-up period was 38 months (range 1 - 128 months). The complete response (CR) rate of ASCT group increased from 27.1% (19/70) before ASCT to 51.4% (36/70) after ASCT. The median PFS of ASCT group was significantly higher than non-ASCT group (45 months vs. 25 months, P < 0.001). The median OS of ASCT group was also significantly higher (55 months vs. 30 months, P = 0.016). Single-factor analysis showed that International Staging System (ISS) stage, very good partial response (VGPR) or better outcome were significantly correlated with PFS and OS (P < 0.001). Multi-factor analysis showed that whether or not VGPR or better outcome was achieved were independent factors influencing the disease prognosis.</p><p><b>CONCLUSION</b>Used as a consolidation therapy, ASCT can achieve better responses and higher OS and PFS of MM patients.</p>
