Secukinumab during pregnancy: a case report and review of literature

Exposure to biologic therapy before and during pregnancy in patients with psoriasis: Systematic review and meta-analysis

Biologicals have transformed the management of severe disease phenotypes in psoriasis and are often prescribed in women of childbearing age. However, information on safety of biologicals in pregnancy are lacking. We conducted a systematic review and meta-analysis aimed to describe the characteristics and pregnancy outcomes in women with psoriasis exposed to biologics within 3 months before or during pregnancy, and to estimate the pooled prevalence of spontaneous, elective and total abortions, and congenital malformations in their newborns. Bibliographic searches were performed in the PubMed, Embase, Scopus and Web of Science databases up to 14 April 2022. No restrictions on sample size or publication date were applied. Review performance complied with PRISMA guidelines, and two reviewers assessed randomized controlled trials and nonrandomized studies reporting pregnancy outcomes in women exposed to biologics indicated for psoriasis during the pre-gestational and/or gestational period. Studies focusing on rheumatologic or gastroenterological immune-mediated inflammatory diseases were excluded. Regardless of data heterogeneity, a random-effects model was used to pool prevalence estimates. We included 51 observational studies, involving 739 pregnancies exposed to approved biologics for psoriasis. Administration was mostly (70.4%) limited to the first trimester, and the most common drug was ustekinumab (36.0%). The estimated prevalence of miscarriage was 15.3% (95% confidence interval [CI] 12.7-18.0) and elective abortions, 10.8% (95% CI 7.7-14.3). Congenital malformations occurred in about 3.0% (95% CI 1.6-4.8) of live births exposed to biologics during pregnancy. Altogether, exposure to biologics for psoriasis during pregnancy and/or conception does not seem to be associated with an increased risk of miscarriage/abortion or congenital malformations, showing similar rates to the general population. These results suggest that biologic drugs are safe and pose an acceptable risk to the foetuses/neonates.

Therapy of psoriasis during pregnancy and breast-feeding

There have been multiple systemic drugs approved for the therapy of psoriasis vulgaris and psoriasis arthritis (PsA) in the last decade. However, treatment decisions are difficult to make in women planning a pregnancy and in pregnant and lactating women due to the paucity of data for such cases. The strongest evidence for psoriasis therapy during pregnancy exists for topical corticosteroids. Medically controlled use of UVB-therapy is also considered safe. The best evidence regarding systemic therapy during pregnancy and lactation is available for the group of TNF-alpha inhibitors, which is also reflected in the respective medical product information. This is especially important in cases of psoriatic arthritis. Among traditional systemic therapeutics, the largest clinical experience exists for ciclosporin, which, if medically necessary, may be continued during gestation. However, TNF-alpha inhibitors, especially the pegylated form, should be preferred in case of pregnancy. Furthermore, an elective pregnancy termination is not necessary due to systemic therapy of psoriasis with many further substances during the first pregnancy weeks. The current work provides a comprehensive review of the scientific literature on treatment of psoriasis during pregnancy and lactation. Based on the available scientific information, severity of psoriasis and patient's comorbidities, the best possible therapeutic approach can be found in consensus with the patient.

A case of impetigo herpetiformis in which termination of pregnancy was required

Impetigo herpetiformis is a rare variant of generalized pustular psoriasis that occurs during pregnancy or is triggered by pregnancy, often in association with hypocalcemia. This condition is associated with increased maternal and fetal morbidity and mortality. We report a 29-year-old pregnant woman who presented to hospital at the gestational age of 20 weeks with widespread erythema covered with pustules that coalesced to form lakes of pus. She did not respond to corticosteroids, immunosuppressants, or phototherapy. Finally, intra-amniotic injection of ethacridine lactate was administered to terminate the pregnancy, and the patient showed complete recovery in 3 months. Insight from this case report may facilitate optimal management of this relatively rare entity.
