[Conception and course of eight pregnancies in five women on TNF blocker etanercept treatment].
The introduction of tumor necrosis factor (TNF)-α inhibitors s in the late 1990s considerably broadened the treatment options for, and essentially contributed to the successful management of, rheumatoid arthritis (RA) and other immune-mediated inflammatory diseases. Nevertheless, their use during pregnancy is still controversially discussed since it remains unclear whether the benefits of treatment might be outweighed by potential teratogenicity or adverse effects on the course of pregnancy. In this case series report we describe the course and outcome of eight pregnancies in five women (four with RA and one with ankylosing spondylitis) at our private clinical practice treated with the TNF-α inhibitor etanercept at the time of conception and during pregnancy. The course was inconspicuous in six of the eight pregnancies; in one case a megacolon congenitum was diagnosed 2 weeks after birth, while one spontaneous abortion occurred in the 10th week of pregnancy after a disease flare following treatment discontinuation with etanercept in the 5th week of pregnancy. Based on our experience to date and the currently available literature data, we believe that continuation of treatment with TNF-α blockers is justified in pregnant patients with otherwise high disease activity and disease progression.
