Monkeypox infection in pregnancy: a systematic review and metaanalysis.


ABSTRACT:

Objective

The World Health Organization has recently declared a monkeypox outbreak as a public health emergency of global concern. The main aim of this systematic review was to ascertain the maternal and perinatal outcomes of pregnancies complicated by monkeypox infection.

Data sources

The Medline, Embase, and Cochrane databases were searched on June 25, 2022 utilizing combinations of the relevant medical subject heading terms, key words, and word variants for "monkeypox" and "pregnancy."

Study eligibility criteria

The search and selection criteria were restricted to the English language.

Methods

The outcomes observed were miscarriage; intrauterine, neonatal, and perinatal death; preterm birth, vertical transmission, and maternal symptoms. A metaanalysis of proportions was used to analyze the data.

Results

Four studies were included. All the cases in the present systematic review presented with symptoms and signs of monkeypox infection. There was no case of maternal death. Miscarriage occurred in 39% of cases (95% confidence interval, 0-89.0), whereas intrauterine fetal death occurred in 23.0% (95% confidence interval, 0-74.0) of cases. The overall incidence of late fetal and perinatal loss was 77.0% (95% confidence interval, 26.0-100), whereas only 23% (95% confidence interval, 0-74.0) of the included fetuses survived to birth. The incidence of preterm birth before 37 weeks of gestation was 8.0% (95% confidence interval, 0-62.0). Vertical transmission occurred in 62.0% (95% confidence interval, 3.0-100) of cases. When stratifying the analysis according to gestational age at infection, fetal loss was found to occur in 67.0% (95% confidence interval, 9.0-99.0) of cases with first-trimester infection and in 82.0% (95% confidence interval, 17.0-100) of those with second-trimester infection.

Conclusion

Monkeypox infection in pregnancy is associated with a high risk of perinatal loss and vertical transmission. The preliminary results from this systematic review affected by a very small number of included cases highlight the need for thorough maternal and fetal surveillance in pregnancies complicated by monkeypox infection.
