Problem In chronic hepatitis B ( CHB ) carriers, alanine transaminase ( ALT ) flares are common in the peripartum period. There are limited data on immunological changes of pregnancy in CHB . We hypothesize that in pregnant CHB carriers, the Th1/Th2 cytokine ratio is altered resulting in changes in biochemical/virological and liver fibrosis markers. Study methods Serum from 38 pregnant/post‐partum CHB carriers (median age 32 years, 53% Asian, 8 HB eAg + ) was tested for HBV DNA , quantitative HBV surface antigen, ALT and liver fibrosis by transient elastography ( TE ). Serum cytokines were analyzed using a Luminex assay. Results Untreated CHB cases had mild ALT flares post‐partum, but showed normal TE , and no change in viral markers despite increased Th1 cytokines compared to healthy controls ( P <.05). Conclusion CHB carriers show increased Th1 cytokines in the peripartum period albeit with no effect on viral load or liver disease suggesting an aborted antiviral immune response.
