[Prevention and factors associated with anti-HCV carriage in pregnant women living in Cotonou].

INTRODUCTION

hepatitis C is an infection which can be passed from mother to child. The purpose of this study was to investigate the prevalence of colonization by anti-HCV antibodies in pregnant women living in Cotonou and to identify factors associated with it.

METHODS

we conducted a cross-sectional study of 253 pregnant women admitted for prenatal care in four major maternity hospitals in Cotonou (Benin) from 01/06/2018 to 01/09/2018. Anti-HCV antibodies were detected using rapid diagnostic tests. A venous blood sample was collected from pregnant women tested positive for anti-HCV before confirmatory serological tests and screening tests for gestational diabetes.

RESULTS

the prevalence of anti-HCV antibodies was 1.2% (3/253 pregnant women). Factors associated with HCV carriage couldn't be identified given the low number of positive cases. However, pregnant women who were carriers of hepatitis C antibodies had higher mean age (32 ± 3) compared to the remainder of the population (29.58 ± 5.5). Potential risk factors for HCV infection were scarifications, piercing, tattooing, sharing of manicure equipment, a history of surgery and blood transfusions. The prevalence of gestational diabetes in our study population was 7.9% (20/253). No association was found between gestational diabetes and hepatitis C.

CONCLUSION

the prevalence of anti-HCV antibodies in pregnant women living in Cotonou was low. A national-level study is needed to identify factors associated with this infection.
