RESUMO
BACKGROUND: Cytomegalovirus (CMV) infection among pregnant females could induce CMV hepatitis with possible changes in liver stiffness measurement (LSM) which could be reversibly increased during normal pregnancies, particularly in the third trimester. This study aimed to detect the prevalence of CMV infection among pregnant females with and without chronic liver disease and to evaluate the effects of CMV infection on LSM and pregnancy outcomes in comparison to non-CMV-infected pregnant females. METHODS: This is an observational prospective study that included 201 pregnant ladies presented to the liver disease with pregnancy clinic, Cairo University from March 2018 to April 2019. We assessed the laboratory results, abdominal ultrasonography, LSM using ARFI elastography, and pregnancy outcomes. RESULTS: Two hundred and one pregnant ladies were divided into ; group 1: pregnant ladies with normal pregnancy (n = 128), group 2: pregnant ladies with chronic liver diseases not related to pregnancy (n = 35), and group 3: pregnant ladies with pregnancy-related liver diseases (n = 38). Positive CMV serology (either/or, +ve CMV-IgM, IgG) was detected in 106/201 patients (52.74%), and fifteen of them had an active infection (IgG +, IgM+, PCR+). Pregnant females with chronic liver diseases not related to pregnancy had significantly higher serum levels of CMV IgM, IgG, and PCR. Moreover, LSM had a significant correlation with CMV IgG and CM_PCR in normal pregnant ladies. Maternal mortality occurred only in pregnant females with chronic liver diseases in 5.7% (2/35). CONCLUSION: Maternal CMV infection carries a significant risk to pregnant females with chronic liver disease. Routine CMV screening for women planning to be pregnant, especially those with chronic liver disease could help to avoid bad maternal and fetal outcomes.
