Pathogenesis, diagnosis, and treatment of recurrent spontaneous abortion with immune type

Qi-De LIN, Li-Hua QIU

摘要： Recurrent spontaneous abortion (RSA), defined as three or more consecutive pregnancy losses before 20 weeks of gestation, is difficult to treat in the clinical setting. It affects 1%–5% of women of reproductive age. In the investigations of immunopathogenesis, diagnosis, and treatment of RSA since the late 1980s, it was found that RSA was associated with abnormal maternal local or systemic immune response. The pathogenesis of autoimmune RSA was mainly associated with antiphospholipid antibody (APA), while that of alloimmune RSA was due to the disturbance of maternofetal immunological tolerance. Systemic etiological screening process and diagnosis systems of RSA with immune type were developed, and anticardiolipin (ACL or ACA) + anti-β2-GP1 antibody combining multiple assays for effective diagnosis of RSA with autoimmune type was first established. According to the dynamic monitoring of clinical parameters before and during gestation, low-dose, short-course, and individual immunosuppressive therapy and lymphocyte immunotherapy for RSA with immune type were carried out. The outcomes of the offsprings of patients with RSA were followed up, and the safety and validity of the therapies were confirmed. The research achievement leads to great progress in the diagnosis and treatment of RSA in China.

摘要： In recent years, studying the role of myeloid-derived suppressor cells (MDSCs) in many pathological inflammatory conditions has become a very active research area. Although the role of MDSCs in cancer is relatively well established, their role in non-cancerous pathological conditions remains in its infancy resulting in much confusion. Our objectives in this review are to address some recent advances in MDSC research in order to minimize such confusion and to provide an insight into their function in the context of other diseases. The following topics will be specifically focused upon: (1) definition and characterization of MDSCs; (2) whether all MDSC populations consist of immature cells; (3) technical issues in MDSC isolation, estimation and characterization; (4) the origin of MDSCs and their anatomical distribution in health and disease; (5) mediators of MDSC expansion and accumulation; (6) factors that determine the expansion of one MDSC population over the other; (7) the Yin and Yang roles of MDSCs. Moreover, the functions of MDSCs will be addressed throughout the text.
