Hypothesis

Does the presence of ampicillin-resistant uropathogens in acute antepartum pyelonephritis affect clinical outcomes in pregnant women?

Conclusion

Most uropathogens were ampicillin resistant, but there were no differences in clinical outcomes for patients with resistant organisms.

Supporting Evidence

  • 51% of uropathogens were ampicillin resistant.
  • Patients with ampicillin-resistant organisms did not have higher complication rates.
  • 72% of cases had urine cultures with identification of organism and antibiotic sensitivities.

Takeaway

This study looked at pregnant women with a kidney infection and found that even though many germs were resistant to a common antibiotic, the patients did just as well as those with germs that weren't resistant.

Methodology

This was a secondary analysis of a prospective cohort study involving 440 pregnant women diagnosed with acute pyelonephritis.

Limitations

The study only included inpatients, and the findings may not apply to outpatients; also, antibiotic sensitivities were only performed on Gram-negative organisms.

Participant Demographics

The patients with ampicillin-resistant organisms were more likely to be older and multiparous.
