We report two pemphigus patients who became during treatment; in both cases, the pregnancy and delivery proceeded without worsening of symptoms. Because pemphigus is a disease that usually affects women in their 4th to 6th decades, there have been few reports of pregnancy and childbirth. We investigated the effects of treatment and childbirth in 8 Japanese pemphigus patients, including our own cases. All the patients received prednisolone 6 to 20 mg/day. In 4 cases, neonatal pemphigus occurred but did not correlated with maternal antibody titer or treatment. We also present a draft of criteria for acceptance of pregnancy in patients with pemphigus; it is based on the acceptance, management, and treatment of pregnancies complicated by SLE.
The package insert for tacrolimus ointment (Protopic® 0.1% ointment, 0.03% ointment) has been reviewed and revised based on the collected high-evidence safety data from both Japanese and foreign epidemiological studies. The risk of carcinogenicity has been removed from the warning, and the contraindication for its use in pregnant women has also been removed. Therefore, tacrolimus ointment can now be used for pregnant and lactating women under the physician's careful supervision. Epidemiological data indicate that the long-term use of tacrolimus ointment is unlikely to increase the risk of skin infections, and a 10 year follow-up study has confirmed the safety of its use in pediatric patients. Consequently, it is important to provide adequate treatment options after fully explaining the new safety profile of this drug to patients and ensuring their thorough understanding.
