Background: HCMV is a prevalent virus that affects a significant section of the human population, causes severe disease, and affects the fetus in pregnant women. hcmv-miRNAs are important regulatory molecules in miscarriages in women CMV-infected. Objective: To evaluate the association of hcmv-miR-UL36-5P gene expression with miscarriages in women with HCMV. Methods: A case-control study was designed to include 140 women who had miscarriages at random, and 50 of them who had miscarriages with a high CMV viral load were categorized as miscarriage groups. Additionally, 50 healthy pregnant women who had not previously experienced miscarriages were included as a control group. After diagnosis of HCMV IgM and IgG via the VIDAS assay and CMV viral load detected by qPCR, RNA was extracted from blood samples to measure the hcmv-miR-UL36-5P gene expression by qPCR technique. Results: The results revealed that out of 140 women with miscarriages, 50(35.7%) were seropositive for CMV, while 90(64.3%) were seronegative for CMV, and show that only 3(6.0%) samples were seropositive to CMV IgM, 8(16.0%) seropositive for both CMV IgM and IgG, and 39(78.0%) were seropositive for CMV IgG. The expression of hcmv-miR-UL36-5P in miscarriage women was 3.11-fold higher than the control group. Conclusions: Upregulated expression of the hcmv-miR-UL36-5P gene in women with miscarriage confirms its role in miscarriage. These miRNAs may contribute to the pathogenesis of HCMV infection and its involvement in pregnancy complications.
