Problem  The purpose of this study was to investigate whether treatment with TNF-α inhibitors and/or intravenous immunoglobulin (IVIG) increases in vitro fertilization (IVF) success rates among young (<38 years) women with infertility and T helper 1/T helper 2 cytokine elevation.

Method of study  Seventy-five sub-fertile women with Th1/Th2 cytokine elevation were divided into four groups: Group I: Forty-one patients using both IVIG and Adalimumab (Humira®), Group II: Twenty-three patients using IVIG, Group III: Six patients using Humira®, and Group IV: Five patients using no IVIG or Humira®.

Results  The implantation rate (number of gestational sacs per embryo transferred, with an average of two embryos transferred by cycle) was 59% (50/85), 47% (21/45), 31% (4/13) and 0% (0/9) for groups I, II, III and IV respectively. The clinical pregnancy rate (fetal heart activity per IVF cycle started) was 80% (33/41), 57% (13/23), 50% (3/6) and 0% (0/5) and the live birth rate was 73% (30/41), 52% (12/23), 50% (3/6) and 0% (0/5) respectively. There was a significant improvement in implantation, clinical pregnancy and live birth rates for group I versus group IV (P = 0.0007, 0.0009, and 0.003, respectively) and for group II versus group IV (P = 0.009, 0.04 and 0.05, respectively).

Conclusion  The use of a TNF-α inhibitor and IVIG significantly improves IVF outcome in young infertile women with Th1/Th2 cytokine elevation.
