The major risk factor of perinatal transmission of Hepatitis B virus (HBV) infection is the level of maternal HBV-deoxyribonucleic acid (DNA) during the third trimester of pregnancy. The primary aim of this study was to evaluate the hematological and biochemical status in Hepatitis B e-antigen (HBeAg)-negative chronic HBV-infected pregnant women and to correlate the findings with the presence or absence of viremia. Ninety-five consecutive chronic HBV-infected pregnant women were evaluated between the 28th and 32nd week of gestation. Viral load was determined by using the COBAS TaqMan HBV test. Sixty-nine women were evaluated and 14 of them exhibited HBV-DNA levels higher than 2000 IU[middle dot]ml. In this study, viremic women exhibited significantly higher alanine aminotransferase (ALT), creatinine, and uric acid values as well as significantly lower white blood cell count compared with nonviremic women. There was also a significant statistical difference concerning ALT/sodium ratio between viremic and nonviremic women (0.20 +/- 0.22 vs. 0.10 +/- 0.09, respectively, p= .024). The optimal cutoff points discriminating those women with a high probability to have detectable serum HBV-DNA were 0.092 for ALT/sodium ratio (sensitivity = 73.0%, specificity = 61.5%, area under the receiver operating characteristic curve [AUC] = 71.05%) and 12.8 IU/L for ALT (sensitivity = 73.0%, specificity = 63.0%, AUC = 72.2%). Chronic HBV-infected pregnant women with ALT/sodium ratio >= 0.11 had the higher probability of having serum HBV-DNA levels higher than 2000 IU/ml (sensitivity = 76.92%, specificity = 58%, AUC = 62.38%). Presence of HBV-DNA in maternal blood during the third trimester of pregnancy is significantly associated with maternal serum ALT levels in HBeAg-negative chronic HBV-infected pregnant women. Women with an ALT/sodium ratio greater than 0.092 have the higher probability of HBV-DNA presence in maternal blood whereas an ALT/sodium ratio greater than 0.11 could discriminate those women with HBV-DNA levels higher than 2000 IU/ml.
