Abstract

A prospective study was undertaken to determine the effect on liver function tests of a combined oral contraceptive containing norethisterone 1 mg and mestranol 0.05 mg, in women with schistosomiasis japonica in Leyte, Philippines. Women who volunteered and met the standard criteria for oral contraception, with and without infection, were followed for six months of pill intake. Concurrently, non-pill users, both infected and uninfected, were similarly followed. Baseline and six-month liver function tests were compared. Of the 466 subjects admitted in the study, 383 completed six months, and 83 discontinued. At the start of the study, there were no significant differences among the four groups in liver function tests except that the infected women had a higher total protein and alkaline phosphatase, and lower alanine aminotransferase levels. After six months, the only statistically significant finding was a lesser decrease in total protein among the infected pill users compared to the uninfected pill users. This finding was not clinically significant since there was no associated clinical complications; there were fewer number of subjects with abnormal values at the sixth month; and the mean values of this variable remained within normal limits. Our findings show that the use of low dose progestin and estrogen oral contraceptive in the presence of mild schistosomiasis japonica infection does not appear to have adverse effect on liver function tests of young women after six months of contraceptive use.
