The relationship of pregnancy losses with frequently-used hematologic parameters

Abstract

Aim: Recurrent pregnancy loss (RPL) is a common and undesirable condition in hematology and obstetrics practice. Pathogenesis for most cases remains undetermined. Thrombophilia may be a potential factor for these patients. Here, we aimed to investigate hematological parameters that have the potential to contribute to or predict RPL and to present our data as a single-center experience. Materials and Methods: One hundred seventy female patients with at least one pregnancy loss between the years 2012 and 2024 were included retrospectively. The mean age of the patients was 34.48 ± 6.02. Patients with antiphospholipid antibodies and miscarriage due to an identifiable etiology (maternal anatomic and endocrine abnormalities, infectious causes, trauma, chromosomal abnormalities) were excluded from the study. Patients were divided into two groups, defined as patients with one or two miscarriages and more than two miscarriages, respectively. Thrombophilia screening tests (mutations and protein C/S/antithrombin levels), blood count and coagulation parameters were recorded and investigated whether there was a significant correlation in terms of miscarriage in the two groups. Results: Nine patients (5.3%), 71 patients (41.8%), 60 patients (35.3%), 21 patients (12.4%), four patients (2.4%), and five patients (2.9%) had a history of one, two, three, four, five, and six miscarriages, respectively. No significant difference was found between the genetic mutations investigated in terms of thrombophilia, protein C, S, and antithrombin levels, and the number of pregnancy losses in both groups. There was no significant difference between hemogram parameters and coagulation parameters except aPTT for both groups. The aPTT value of group B was found to be significantly lower than that of group A (p=0.04). Conclusion: Conflicting results in hematologic parameters in case of RPL are common and it is not easy to obtain homogeneous results. However, a low aPTT value, a parameter that can be easily and quickly measured, may be a parameter that can help predict RPL.
