The Effect of Combined Estrogen and Progesterone Hormone Replacement Therapy on Disease Activity in Systemic Lupus Erythematosus: A Randomized Trial

Abstract

Adding a short course of HRT is associated with a small risk for increasing the natural flare rate of lupus. Most of these flares are mild to moderate. The benefits of HRT can be balanced against the risk for flare because HRT did not significantly increase the risk for severe flare compared with placebo.
