Infection and acute respiratory distress syndrome during pregnancy: a case series of preventable maternal deaths from southern India

Case Report: Typhoid Fever Complicated by Acute Respiratory Distress Syndrome in a Pediatric Traveler

Acute respiratory distress syndrome (ARDS) is seldom described as a complication of typhoid fever (TF). Only 13 cases have hitherto been reported in the English and non-English literature since 1990. We report an 8-year-old boy with TF after return from India who developed pediatric ARDS (pARDS) despite adequate antibiotic treatment. Among patients with available information including this case, we noted that most not born or raised in a TF-endemic country (4/6) compared with none (0/6) of the domestic cases in a TF-endemic country developed ARDS within 48 hours of starting the antibiotic treatment. Our case raises important questions regarding the frequency, pathophysiology, and appropriate management of ARDS and pARDS in patients with TF.

Characteristics and pregnancy outcomes of patients with severe pneumonia complicating pregnancy: a retrospective study of 12 cases and a literature review

Background

Pneumonia during pregnancy has been proven to be associated with increased maternal and fetal morbidity and mortality. The management of severe pneumonia in gravid patients is even more challenging. Thus, we summarized the characteristics and pregnancy outcomes of these patients and explored the probable risk factors and predictive factors for pneumonia during pregnancy and the appropriate timing of delivery in severe pneumonia patients.

Methods

A retrospective cohort study was conducted with 12 patients who were diagnosed with severe pneumonia complicating pregnancy at Peking Union Medical College Hospital between January 2010 and June 2017. The clinical features, treatment strategies, and pregnancy outcomes were collected from medical records and telephone calls.

Results

All 12 patients were in their late second or third trimester. The patients had a higher prevalence of anemia (50%) and preeclampsia (25%) than ordinary pregnant women. Delayed diagnoses were not uncommon. Two mothers died in our series, resulting in a mortality rate of 17%. Two intrauterine deaths were observed. Elective delivery was not performed in any of the four patients in their second trimester. Six of the seven patients who presented after 28 weeks of gestation and had live fetuses underwent emergency deliveries. Preterm births (6/7) and cesarean sections (5/7) were the two leading adverse outcomes in newborns.

Conclusions

Anemia, advanced gestational age, and preeclampsia might be associated with the severity of pneumonia. Chest radiographs should be taken as soon as pneumonia is highly suspected to facilitate an early diagnosis. High incidences of adverse fetal outcomes were observed; thus, termination of the pregnancy is recommended for patients in their third trimester when respiratory function deteriorates progressively. However, it might be reasonable to continue pregnancy for those in their first or second trimester.
