The role of calprotectin in obstetrics and gynecology.

The purpose of this article is to create the first complete review concerning the role of calprotectin, a calcium- and zinc-binding protein of the S100/calgranulins family, in obstetrics and gynecology. A Medline search was conducted between 6 and 8 June 2009 using the term calprotectin and its synonyms combined with the following ones: calprotectin, obstetrics and gynecology, breast cancer, ovarian cancer, endometrial cancer, cervical cancer, menstrual cycle, pregnancy, fetal implantation, labor, intra-amniotic inflammation, preeclampsia, HELLP syndrome, Rh(-) incompatibility. We found 46 studies which referred to obstetrics and gynecology. We excluded 11 studies which referred to obstetrics and gynecology but did not include enough information about calprotectin, and another two which referred to calprotectin but were not related to subjects of obstetrics and gynecology. Thus, we ended up with 33 studies which contained sufficient information to extract data for this review. All the articles were written in English. It was found that calprotectin is associated with many physiologic and pathologic processes in obstetrics and gynecology, such as: breast cancer, ovarian cancer, endometrial cancer, cervical cancer, cervical and vaginal physiology, menstrual cycle, pregnancy and labor. The role of calprotectin in these conditions is significant. In conclusion, the role of calprotectin seems to be important in several issues of obstetrics and gynecology. For example, calprotectin could be used as a diagnostic, prognostic or metastatic marker in several types of cancer, as a marker of inflammation and as a pharmaceutical target in many conditions. Further studies must be conducted to elucidate this role. Copyright (c) 2010 Elsevier Ireland Ltd. All rights reserved.
