Postpartum purulent-inflammatory diseases are currently a serious problem. Purpose - to develop and implement of a new modern method of the diagnosis, monitoring and assessment of health of women during pregnancy, before childbirth and in the postpartum period - the method of fluorescence spectroscopy - to ensure the provision of highly qualified medical care, including the effective treatment. Materials and methods. The research material consisted of blood serum samples of 265 patients. There were 40 pregnant women (the Group 1), 40 women with an uncomplicated postpartum period (the Group 2), 170 - with postpartum purulent-inflammatory diseases (the Group 3), 15 patients with sepsis (the Group 4). Diagnostic methods: clinical, laboratory, instrumental, method of fluorescence spectroscopy, statistical (logistic regression and ROC analysis methods). Results. In the Group 1 there is an increase in the intensity of fluorescence to 1.3 r.u. For the Group 2 the intensity of fluorescence was within 0.86-1.0 r.u. For the Group 3, the decrease in fluorescence intensity from 1 to 0.35 r.u. was recorded. For the Group 4 in addition to decreasing the fluorescence intensity, a noticeable shift of the fluorescence spectra of blood serum into the long-wave range was recorded. Conclusions. A reliable prognostic model of the development of postpartum purulent-inflammatory diseases was created. The modern approach for the diagnosis and effective control of treatment within the framework of the method of fluorescent spectroscopy and biomarkers using infusions of donor albumin solutions is proposed. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors.
