Abstract

Objective: To compare the clinical courses and outcomes of pregnant severe acute respiratory syndrome (SARS) patients and non-pregnant SARS patients.

Design: A case-control study.

Setting: Tertiary Hospital for Infectious Disease. Sample Ten pregnant and 40 non-pregnant female patients infected with SARS.

Methods: Clinical course and outcomes of pregnant SARS patients were compared with a group of non-pregnant SARS patient. Cases and controls were matched with respect to sex, age, timing of contracting SARS, health care workers status and underlying illness.

Main outcome measures: The incidence of intensive care unit admission, intubation, medical complications and death rate.

Results: Pregnancy had no discernible impact on clinical symptoms and presentation delay. Four out of the 10 pregnant patients, nevertheless, required endotracheal intubation and six were admitted to the intensive care unit (ICU), as compared with 12.5% intubation rate (P= 0.065) and 17.5% ICU admission rate (P= 0.012) in the non-pregnant group. More pregnant SARS patients developed renal failure (P= 0.006) and disseminated intravascular coagulopathy (P= 0.006), as compared with non-pregnant SARS group. There were three deaths in the pregnant group, whereas there was no death in the non-pregnant control group (P= 0.006).

Conclusion: Pregnant women with SARS experience a worse clinical course and poorer outcomes compared with non-pregnant women.
