Abstract

The association between estrogen-containing oral contraceptives and history of pregnancies with disease severity in women with polycystic liver disease (PLD) is unclear. We performed a cross-sectional cohort study to assess this association by selecting female patients with PLD of which imaging was available prior to any liver volume-reducing therapy. Patients received a questionnaire to collect detailed information on estrogen use and pregnancies. Preplanned subgroup analyses were performed on premenopausal and postmenopausal patients. The questionnaire was returned by 287 of 360 selected patients (80%). There was no significant association between estrogen-containing oral contraceptives and height-adjusted total liver volume (hTLV) in the total group (P = 0.06) and postmenopausal subgroup (P = 0.7). By contrast, each year of exposure corresponds with a 1.45% higher hTLV (P = 0.02) in the premenopausal subgroup, equivalent to a 15.5% higher hTLV for every 10 years of use. Pregnancy duration was not associated with hTLV. In conclusion, patients with PLD should avoid exogenous estrogens.

Categorical analysis. Categorical analysis for premenopausal (a) and postmenopausal subgroups (b). Estrogen‐containing oral contraceptives use (years) on the y‐axis and disease severity: mild (height‐adjusted total liver volume (hTLV) < 1,600 mL/m), moderate (hTLV 1,600–3,200 mL/m), and severe (>3,200 mL/m) on the x‐axis. All data points represent individual patients. Mean and 95% confidence interval are superimposed.
