Pregnancy and leprosy: a comprehensive literature review

ABSTRACT

The interaction between pregnancy, leprosy and leprosy reactions was examined in a systematic literature review. Several retrospective case series and one retrospective cohort study but only one prospective cohort study were identified in the English literature. Type 1 (reversal) reactions were particularly likely to occur during the post partum. This temporal association was also present for both overt and silent neuritis. Type 2 (erythema nodosum leprosum) reactions occur throughout pregnancy and during lactation, and may be severe and recurrent. No prospective, controlled studies were found that documented the complications of pregnancy in women treated with multidrug therapy regimens. Our study highlights the need for such studies, with appropriate controls, on women throughout pregnancy and lactation so that risk factors for reaction and neuritis during pregnancy can be identified and quantified.
